Psychosocial interventions for recurrent abdominal pain (RAP) and irritable bowel syndrome (IBS) in childhood

The psychosocial needs of adolescent and young adult kidney transplant recipients, and associated interventions: a scoping review

BACKGROUND

Renal transplantation is considered the gold standard treatment for end-stage kidney disease. Adolescent and young adult kidney transplant recipients have the highest rate of graft loss amongst transplanted patients. It is largely accepted this is due to psychosocial and behavioural difficulties, which impact adherence to prescribed therapies. This phenomenon is not isolated to a particular healthcare system having been observed in multiple countries across different continents. It is a global issue of concern. We sought to review the psychosocial needs of these patients, and the interventions designed to meet these needs.

METHODS

A scoping review was conducted based on Arksey and O'Malley's six-stage framework. Eligibility criteria included primary studies of any type that investigated the psychosocial needs of adolescent and/or young adult renal transplant recipients or studies which examined interventions designed to address these needs. Search strategies were developed and conducted on PsycINFO, PubMed, Embase, and CINAHL. Articles meeting the inclusion criteria were critically reviewed using a descriptive-analytical narrative method.

RESULTS

Thirty-nine studies met our inclusion criteria, 30 of which related to psychosocial needs, and the remainder examined psychosocial interventions. Four main themes were derived from our analysis of psychosocial needs literature, as follows: the need for (1) emotional support, (2) acceptance, (3) direction, (4) equality in healthcare. 2 main themes emerged from analysis of psychosocial intervention literature, namely: psychosocial (1) capability, (2) assessment. Despite the evidence that graft health is strongly associated with psychosocial wellbeing, findings revealed a significant lack of literature investigating how best to meet psychosocial needs. Trends were observed amongst intervention studies, namely interventions of novel and non-evidenced based design, with the aim of improving medication adherence through organisational strategies and education. However, literature regarding psychosocial needs showed non-adherence to therapies was not simply a result of disorganisation or lack of understanding, but rather, was founded on a recipient's idiosyncratic relationship with their prescribed therapies e.g., psychological, social or financial reasons for non-adherence.

CONCLUSIONS

Future research should be directed at investigating the efficacy of evidence-based interventions that empower the individual patient to overcome their specific barrier to an optimal relationship with their therapies.

Scientific Evidence for the Treatment of Children with Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is one of the most common functional gastro-intestinal disorders which significantly impacts the quality of life of affected children. Abdominal pain improved by defecation, associated with a change in stool form and frequency, represents its specific clinical marker. Even if a number of potential patho-physiological mechanisms have been described, the exact underlying etiology of IBS is so far unclear. Likewise, no optimal treatment has ever been found neither for adult nor for pediatric patients. Current therapeutic options include drugs, dietary interventions and biopsychosocial therapies. The present review aims at evaluating the scientific evidence supporting the efficacy of these treatments for children with IBS.

An Intervention With Dance and Yoga for Girls With Functional Abdominal Pain Disorders (Just in TIME): Protocol for a Randomized Controlled Trial

BACKGROUND

Functional abdominal pain disorders (FAPDs) affect many children worldwide, predominantly girls, and cause considerable long-term negative consequences for individuals and society. Evidence-based and cost-effective treatments are therefore strongly needed. Physical activity has shown promising effects in the practical management of FAPDs. Dance and yoga are both popular activities that have been shown to provide significant psychological and pain-related benefits with minimal risk. The activities complement each other, in that dance involves dynamic, rhythmic physical activity, while yoga enhances relaxation and focus.

OBJECTIVE

This study aims to evaluate the effects of a dance and yoga intervention among girls aged 9 to 13 years with FAPDs.

METHODS

The study is a prospective randomized controlled trial among girls aged 9 to 13 years with functional abdominal pain, irritable bowel syndrome, or both. The target sample size was 150 girls randomized into 2 arms: an intervention arm that receives dance and yoga sessions twice weekly for 8 months and a control arm that receives standard care. Outcomes will be measured at baseline and after 4, 8, 12, and 24 months, and long-term follow-up will be conducted 5 years from baseline. Questionnaires, interviews, and biomarker measures, such as cortisol in saliva and fecal microbiota, will be used. The primary outcome is the proportion of girls in each group with reduced pain, as measured by the faces pain scale-revised in a pain diary, immediately after the intervention. Secondary outcomes are gastrointestinal symptoms, general health, mental health, stress, and physical activity. The study also includes qualitative evaluations and health economic analyses. This study was approved by the Regional Ethical Review Board in Uppsala (No. 2016/082 1-2).

RESULTS

Data collection began in October 2016. The intervention has been performed in 3 periods from 2016 through 2019. The final 5-year follow-up is anticipated to be completed by fall 2023.

CONCLUSIONS

Cost-effective and easily accessible interventions are warranted to reduce the negative consequences arising from FAPDs in young girls. Physical activity is an effective strategy, but intervention studies are needed to better understand what types of activities facilitate regular participation in this target group. The Just in TIME (Try, Identify, Move, and Enjoy) study will provide insights regarding the effectiveness of dance and yoga and is anticipated to contribute to the challenging work of reducing the burden of FAPDs for young girls.

Recurrent abdominal pain among adolescents: trends and social inequality 1991-2018

OBJECTIVES

The association between socioeconomic status and recurrent abdominal pain (RAP) among adolescents is an understudied issue. No study has examined whether such an association changes over time. The aim was to examine trends in RAP among adolescents in Denmark from 1991 to 2018, to examine whether there was social inequality in RAP and whether this inequality varied over time.

METHODS

The study used data from the Danish part of the international Health Behaviour in School-aged Children (HBSC) study of nationally representative samples of 11-, 13- and 15-year-olds. This study pooled data from eight comparable surveys from 1991 to 2018, overall participation rate 88.0%, n=30,048. The definition of RAP was self-reported stomach-ache daily or several days per week during the past six months. We reported absolute inequality as prevalence difference in RAP between low and high socioeconomic status and relative inequality as odds ratio for RAP by socioeconomic status.

RESULTS

In the entire study population, 5.6% reported RAP, 3.1% among boys and 7.8% among girls. There was a significant increase in RAP from 1991 to 2018 among boys and girls, test for trend, p<0.0001. The prevalence of RAP was significantly higher in low than high socioeconomic status, OR=1.63 (95% CI: 1.42-1.87). The absolute social inequality in RAP fluctuated with no consistent increasing or decreasing pattern.

CONCLUSIONS

The prevalence of RAP increased from 1991 to 2018. The prevalence was significantly higher among girls than among boys, and significantly higher in low socioeconomic status families. Professionals should be aware of RAP as common and potentially serious health problems among children and adolescents. In addition to clinical examination it is important to focus on improving the child's quality of life, reduce parents' and children's concerns about the seriousness of the condition, and consider supplements to medicine use.

Mapping the evidence and gaps of interventions for pediatric chronic pain to inform policy, research, and practice: A systematic review and quality assessment of systematic reviews

Background: Reviews in pediatric chronic pain often focus on only one intervention or population, making it difficult for policymakers and decision makers to quickly synthesize knowledge to inform larger-scale policy and funding priorities. Aims: The aims of this study were to (1) create an evidence and gap map of interventions for pediatric chronic pain and (2) identify gaps between existing evidence and recently identified patient-oriented research priorities. Methods: We performed a systematic review of English-language peer-reviewed systematic reviews or clinical practice guidelines of pediatric chronic pain intervention published in the past 20 years. Database searches of Medline, Embase, PsycINFO, Web of Science, CINAHL, and SCOPUS were conducted inclusive to June 3, 2019. Review quality was assessed using the AMSTAR-2. Results: Of 4168 unique abstracts, 50 systematic reviews (including 2 clinical practice guidelines) crossing diverse pediatric chronic pain populations and intervention settings were included. One third were rated high quality, with half rated low to critically low quality. The largest proportion of reviews addressed psychological and pharmacological interventions, followed by interdisciplinary, other (e.g., dietary), and physical interventions. Most common outcomes included pain, physical, emotional, and role functioning and quality of life. Treatment satisfaction and adverse events were less common, with minimal report of sleep or economic factors. Most patient-oriented research priorities had not been investigated. Conclusions: Sufficient quality evidence is available to guide evidence-informed policies in pediatric chronic pain, most notably regarding psychological and pharmacological interventions. Numerous evidence gaps in patient-oriented research priorities and treatment outcomes should guide prioritization of research funds, as well as study aims and design.

The correlation of functional pain and psychological distress: a study in Italian school students

Background

Functional Pain (not detectable organic cause) is often associated with psychological problems and, according to literature, it can lead to severe manifestations.

The purpose of the study was to investigate the correlation between functional pain and psychological disagreement, in a series of school students.

Methods

An observational questionnaire-based study was performed.

A questionnaire was given to a group of students of primary school; the following data were collected in the questionnaire: a) sex and age; b) functional pain; c) relation with relatives, teachers and schoolfellows: d) school failure.

Statistical methods: P-value of concordance test and P-value of correlation have been performed with MINITAB 15.1 software.

Results

Eight hundred nine students, 354 females, 455 males, median age 14 years, participated to the study.

Functional Pain was referred from 537/809 students (66%): 265 Females, 272 males: p = 0.155. The difference between the number of pain episodes in females vs. males was statistically significant (p = 0,511), as pain intensity vs. the number of episodes in females (p = 0.001).

The most frequent location of pain was abdomen in females, limbs in males.

Psychological disagreement was referred from 513/809 students (63%) (260 females; 253 males: p = 0,150).

Psychological disagreement was reported with parents (19); siblings (22); other relatives (18); teachers: 42, schoolfellows: 366, relatives as well as school fellows: 46.

The correlation between disagreement and functional pain in all the students included in the study was statistically significant (p < 0.001).

Conclusions

most students reported psychological disagreement and pain. The most frequent cause of disagreement was schoolfellows’ behaviour. The study shows a student’s lack of discussing of their problems with parents, teachers, peer. According to literature, confiance would be a useful treatment for avoiding psychological disagreements and functional pain.

Psychological therapies for the management of chronic and recurrent pain in children and adolescents

BACKGROUND

This is an update of the original Cochrane review first published in Issue 1, 2003, and previously updated in 2009, 2012 and 2014. Chronic pain, defined as pain that recurs or persists for more than three months, is common in childhood. Chronic pain can affect nearly every aspect of daily life and is associated with disability, anxiety, and depressive symptoms.

OBJECTIVES

The aim of this review was to update the published evidence on the efficacy of psychological treatments for chronic and recurrent pain in children and adolescents.The primary objective of this updated review was to determine any effect of psychological therapy on the clinical outcomes of pain intensity and disability for chronic and recurrent pain in children and adolescents compared with active treatment, waiting-list, or treatment-as-usual care.The secondary objective was to examine the impact of psychological therapies on children's depressive symptoms and anxiety symptoms, and determine adverse events.

SEARCH METHODS

Searches were undertaken of CENTRAL, MEDLINE, MEDLINE in Process, Embase, and PsycINFO databases. We searched for further RCTs in the references of all identified studies, meta-analyses, and reviews, and trial registry databases. The most recent search was conducted in May 2018.

SELECTION CRITERIA

RCTs with at least 10 participants in each arm post-treatment comparing psychological therapies with active treatment, treatment-as-usual, or waiting-list control for children or adolescents with recurrent or chronic pain were eligible for inclusion. We excluded trials conducted remotely via the Internet.

DATA COLLECTION AND ANALYSIS

We analysed included studies and we assessed quality of outcomes. We combined all treatments into one class named 'psychological treatments'. We separated the trials by the number of participants that were included in each arm; trials with > 20 participants per arm versus trials with < 20 participants per arm. We split pain conditions into headache and mixed chronic pain conditions. We assessed the impact of both conditions on four outcomes: pain, disability, depression, and anxiety. We extracted data at two time points; post-treatment (immediately or the earliest data available following end of treatment) and at follow-up (between three and 12 months post-treatment).

MAIN RESULTS

We identified 10 new studies (an additional 869 participants) in the updated search. The review thus included a total of 47 studies, with 2884 children and adolescents completing treatment (mean age 12.65 years, SD 2.21 years). Twenty-three studies addressed treatments for headache (including migraine); 10 for abdominal pain; two studies treated participants with either a primary diagnosis of abdominal pain or irritable bowel syndrome, two studies treated adolescents with fibromyalgia, two studies included adolescents with temporomandibular disorders, three were for the treatment of pain associated with sickle cell disease, and two studies treated adolescents with inflammatory bowel disease. Finally, three studies included adolescents with mixed pain conditions. Overall, we judged the included studies to be at unclear or high risk of bias.Children with headache painWe found that psychological therapies reduced pain frequency post-treatment for children and adolescents with headaches (risk ratio (RR) 2.35, 95% confidence interval (CI) 1.67 to 3.30, P < 0.01, number needed to treat for an additional beneficial outcome (NNTB) = 2.86), but these effects were not maintained at follow-up. We did not find a beneficial effect of psychological therapies on reducing disability in young people post-treatment (SMD -0.26, 95% CI -0.56 to 0.03), but we did find a beneficial effect in a small number of studies at follow-up (SMD -0.34, 95% CI -0.54 to -0.15). We found no beneficial effect of psychological interventions on depression or anxiety symptoms.Children with mixed pain conditionsWe found that psychological therapies reduced pain intensity post-treatment for children and adolescents with mixed pain conditions (SMD -0.43, 95% CI -0.67 to -0.19, P < 0.01), but these effects were not maintained at follow-up. We did find beneficial effects of psychological therapies on reducing disability for young people with mixed pain conditions post-treatment (SMD -0.34, 95% CI -0.54 to -0.15) and at follow-up (SMD -0.27, 95% CI -0.49 to -0.06). We found no beneficial effect of psychological interventions on depression symptoms. In contrast, we found a beneficial effect on anxiety at post-treatment in children with mixed pain conditions (SMD -0.16, 95% CI -0.29 to -0.03), but this was not maintained at follow-up.Across all pain conditions, we found that adverse events were reported in seven trials, of which two studies reported adverse events that were study-related.Quality of evidenceWe found the quality of evidence for all outcomes to be low or very low, mostly downgraded for unexplained heterogeneity, limitations in study design, imprecise and sparse data, or suspicion of publication bias. This means our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect, or we have very little confidence in the effect estimate; or the true effect is likely to be substantially different from the estimate of effect.

AUTHORS' CONCLUSIONS

Psychological treatments delivered predominantly face-to-face might be effective for reducing pain outcomes for children and adolescents with headache or other chronic pain conditions post-treatment. However, there were no effects at follow-up. Psychological therapies were also beneficial for reducing disability in children with mixed chronic pain conditions at post-treatment and follow-up, and for children with headache at follow-up. We found no beneficial effect of therapies for improving depression or anxiety. The conclusions of this update replicate and add to those of a previous version of the review which found that psychological therapies were effective in reducing pain frequency/intensity for children with headache and mixed chronic pain conditions post-treatment.

Focus on the use of antidepressants to treat pediatric functional abdominal pain: current perspectives

Chronic abdominal pain is frequently encountered in pediatric practice. A large proportion of cases meet Rome criteria for abdominal pain-functional gastrointestinal disorders (AP-FGIDs). These disorders are costly and, in some cases, lead to impairment of daily functioning and overall quality of life. Pathophysiologic mechanisms include early stressful events, visceral hypersensitivity, dysmotility, changes in intestinal microbiota, and altered central nervous system processing. They are considered disorders of the brain-gut interaction. The diagnosis is made on clinical grounds using symptom-based criteria (Rome criteria). Anxiety and depressive symptoms are more prevalent in patients with AP-FGIDs. Therefore, attention has been directed to the use of neuromodulators as potential interventions for AP-FGIDs. Antidepressants are one type of neuromodulators, and one of the most studied drugs for the management of AP-FGIDs in adult and pediatric population. Data available in pediatric population have significant limitations including nonuniform methodology with different study designs and primary endpoints. Evidence of the efficacy of antidepressants in the management of pediatric AP-FGIDs is not consistent. There is an urgent need for well-designed randomized clinical trials using age-appropriate validated outcome measures. Careful consideration must be given to adverse effects, particularly increased suicidal ideation.

The Management of Paediatric Functional Abdominal Pain Disorders: Latest Evidence

Recurrent abdominal pain (RAP) is one of the most common health complaints in both children and adults. Although RAP is considered a functional disorder rather than an organic disease, affected children and their families can still experience anxiety and concerns that can interfere with school, sports, and regular daily activities and lead to frequent attendances at pediatric emergency departments or pediatric gastroenterology clinics. Our review shows experts do not agree on a universally proven management that will work on every child presenting with functional abdominal pain (FAP). Treatment strategies include both non-pharmacological and pharmacological options. Non-pharmacological treatments are usually very well accepted by both children and their parents and are free from medication side effects. Nevertheless, they may be as effective as the pharmacological interventions; therefore, according to many experts and based on the majority of current evidence, a non-pharmacological approach should be the first intervention attempt in children with RAP. In particular, the importance of the bio-psychosocial approach is highlighted, as a majority of children will improve with counselling and reassurance that no serious organic pathologies are suspected, especially when the physician establishes a trustful relationship with both the child and their family. Placebo and pharmacological interventions could be attempted when the bio-psychosocial approach is not applicable or not efficacious. In some difficult cases, finding an effective treatment for FAP can be a challenge, and a number of strategies may need to be tried before symptoms are controlled. In these cases, a multidisciplinary team, comprising a pediatric gastroenterologist, dietician, psychologist, and psychotherapist, is likely to be successful.

Dietary interventions for recurrent abdominal pain in childhood

BACKGROUND

This is an update of the original Cochrane review, last published in 2009 (Huertas-Ceballos 2009). Recurrent abdominal pain (RAP), including children with irritable bowel syndrome, is a common problem affecting between 4% and 25% of school-aged children. For the majority of such children, no organic cause for their pain can be found on physical examination or investigation. Many dietary inventions have been suggested to improve the symptoms of RAP. These may involve either excluding ingredients from the diet or adding supplements such as fibre or probiotics.

OBJECTIVES

To examine the effectiveness of dietary interventions in improving pain in children of school age with RAP.

SEARCH METHODS

We searched CENTRAL, Ovid MEDLINE, Embase, eight other databases, and two trials registers, together with reference checking, citation searching and contact with study authors, in June 2016.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing dietary interventions with placebo or no treatment in children aged five to 18 years with RAP or an abdominal pain-related, functional gastrointestinal disorder, as defined by the Rome III criteria (Rasquin 2006).

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We grouped dietary interventions together by category for analysis. We contacted study authors to ask for missing information and clarification, when needed. We assessed the quality of the evidence for each outcome using the GRADE approach.

MAIN RESULTS

We included 19 RCTs, reported in 27 papers with a total of 1453 participants. Fifteen of these studies were not included in the previous review. All 19 RCTs had follow-up ranging from one to five months. Participants were aged between four and 18 years from eight different countries and were recruited largely from paediatric gastroenterology clinics. The mean age at recruitment ranged from 6.3 years to 13.1 years. Girls outnumbered boys in most trials. Fourteen trials recruited children with a diagnosis under the broad umbrella of RAP or functional gastrointestinal disorders; five trials specifically recruited only children with irritable bowel syndrome. The studies fell into four categories: trials of probiotic-based interventions (13 studies), trials of fibre-based interventions (four studies), trials of low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diets (one study), and trials of fructose-restricted diets (one study).We found that children treated with probiotics reported a greater reduction in pain frequency at zero to three months postintervention than those given placebo (standardised mean difference (SMD) -0.55, 95% confidence interval (CI) -0.98 to -0.12; 6 trials; 523 children). There was also a decrease in pain intensity in the intervention group at the same time point (SMD -0.50, 95% CI -0.85 to -0.15; 7 studies; 575 children). However, we judged the evidence for these outcomes to be of low quality using GRADE due to an unclear risk of bias from incomplete outcome data and significant heterogeneity.We found that children treated with probiotics were more likely to experience improvement in pain at zero to three months postintervention than those given placebo (odds ratio (OR) 1.63, 95% CI 1.07 to 2.47; 7 studies; 722 children). The estimated number needed to treat for an additional beneficial outcome (NNTB) was eight, meaning that eight children would need to receive probiotics for one to experience improvement in pain in this timescale. We judged the evidence for this outcome to be of moderate quality due to significant heterogeneity.Children with a symptom profile defined as irritable bowel syndrome treated with probiotics were more likely to experience improvement in pain at zero to three months postintervention than those given placebo (OR 3.01, 95% CI 1.77 to 5.13; 4 studies; 344 children). Children treated with probiotics were more likely to experience improvement in pain at three to six months postintervention compared to those receiving placebo (OR 1.94, 95% CI 1.10 to 3.43; 2 studies; 224 children). We judged the evidence for these two outcomes to be of moderate quality due to small numbers of participants included in the studies.We found that children treated with fibre-based interventions were not more likely to experience an improvement in pain at zero to three months postintervention than children given placebo (OR 1.83, 95% CI 0.92 to 3.65; 2 studies; 136 children). There was also no reduction in pain intensity compared to placebo at the same time point (SMD -1.24, 95% CI -3.41 to 0.94; 2 studies; 135 children). We judged the evidence for these outcomes to be of low quality due to an unclear risk of bias, imprecision, and significant heterogeneity.We found only one study of low FODMAP diets and only one trial of fructose-restricted diets, meaning no pooled analyses were possible.We were unable to perform any meta-analyses for the secondary outcomes of school performance, social or psychological functioning, or quality of daily life, as not enough studies included these outcomes or used comparable measures to assess them.With the exception of one study, all studies reported monitoring children for adverse events; no major adverse events were reported.

AUTHORS' CONCLUSIONS

Overall, we found moderate- to low-quality evidence suggesting that probiotics may be effective in improving pain in children with RAP. Clinicians may therefore consider probiotic interventions as part of a holistic management strategy. However, further trials are needed to examine longer-term outcomes and to improve confidence in estimating the size of the effect, as well as to determine the optimal strain and dosage. Future research should also explore the effectiveness of probiotics in children with different symptom profiles, such as those with irritable bowel syndrome.We found only a small number of trials of fibre-based interventions, with overall low-quality evidence for the outcomes. There was therefore no convincing evidence that fibre-based interventions improve pain in children with RAP. Further high-quality RCTs of fibre supplements involving larger numbers of participants are required. Future trials of low FODMAP diets and other dietary interventions are also required to facilitate evidence-based recommendations.

Pharmacological interventions for recurrent abdominal pain in childhood

BACKGROUND

Between 4% and 25% of school-aged children at some stage complain of recurrent abdominal pain (RAP) of sufficient severity to interfere with their daily lives. When no clear organic cause is found, the children are managed with reassurance and simple measures; a large range of pharmacological interventions have been recommended for use in these children.

OBJECTIVES

To determine the effectiveness of pharmacological interventions for RAP in children of school age.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Embase, and eight other electronic databases up to June 2016. We also searched two trials registers and contacted researchers of published studies.

SELECTION CRITERIA

Randomised controlled trials involving children aged five to 18 years old with RAP or an abdominal pain-related functional gastrointestinal disorder, as defined by the Rome III criteria (Rasquin 2006). The interventions were any pharmacological intervention compared to placebo, no treatment, waiting list, or standard care. The primary outcome measures were pain intensity, pain duration or pain frequency, and improvement in pain. The secondary outcome measures were school performance, social or psychological functioning, and quality of daily life.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles, abstracts, and potentially relevant full-text reports for eligible studies. Two review authors extracted data and performed a 'Risk of bias' assessment. We used the GRADE approach to rate the overall quality of the evidence. We deemed a meta-analysis to be not appropriate as the studies were significantly heterogeneous. We have consequently provided a narrative summary of the results.

MAIN RESULTS

This review included 16 studies with a total of 1024 participants aged between five and 18 years, all of whom were recruited from paediatric outpatient clinics. Studies were conducted in seven countries: seven in the USA, four in Iran, and one each in the UK, Switzerland, Turkey, Sri Lanka, and India. Follow-up ranged from two weeks to four months. The studies examined the following interventions to treat RAP: tricyclic antidepressants, antibiotics, 5-HT4 receptor agonists, antispasmodics, antihistamines, H2 receptor antagonists, serotonin antagonists, selective serotonin re-uptake inhibitors, a dopamine receptor antagonist, and a hormone. Although some single studies reported that treatments were effective, all of these studies were either small or had key methodological weaknesses with a substantial risk of bias. None of these 'positive' results have been reproduced in subsequent studies. We judged the evidence of effectiveness to be of low quality. No adverse effects were reported in these studies.

AUTHORS' CONCLUSIONS

There is currently no convincing evidence to support the use of drugs to treat RAP in children. Well-conducted clinical trials are needed to evaluate any possible benefits and risks of pharmacological interventions. In practice, if a clinician chooses to use a drug as a 'therapeutic trial', they and the patient need to be aware that RAP is a fluctuating condition and any 'response' may reflect the natural history of the condition or a placebo effect, rather than drug efficacy.

Do Mothers Benefit from a Child-Focused Cognitive Behavioral Treatment (CBT) for Childhood Functional Abdominal Pain? A Randomized Controlled Pilot Trial

While the efficacy of cognitive-behavioral treatment (CBT) approaches for childhood functional abdominal pain (FAP) is well-established for child outcomes, only a few studies have reported on parent-specific outcomes. This randomized controlled pilot trial analyzed effects of a group CBT on maternal variables (i.e., pain-related behavior, worries and self-efficacy, as well as general psychosocial strain). Methods: The sample constituted of 15 mothers in the intervention group (IG) and 14 mothers in the waitlist control group (WLC). Outcome measures were assessed pre-treatment, post-treatment and at three months follow-up. Results: Analyses revealed significant, large changes in maladaptive maternal reactions related to the child's abdominal pain in the IG compared to the WLC-i.e., reduced attention (d = 0.95), medical help-seeking (d = 0.92), worries (d = 1.03), as well as a significant increase in behaviors that encourage the child's self-management (d = 1.03). In addition, maternal self-efficacy in dealing with a child's pain significantly increased in the IG as well (d = 0.92). Treatment effects emerged post-treatment and could be maintained until three months follow-up. There were no effects on general self-efficacy and maternal quality of life. Conclusion: While these results are promising, and underline the efficacy of the CBT approach for both the child and mothers, further studies, including long-term follow-ups, are warranted.

Psychosocial interventions for recurrent abdominal pain in childhood

BACKGROUND

This review supersedes the original Cochrane review first published in 2008 (Huertas-Ceballos 2008).Between 4% and 25% of school-aged children complain of recurrent abdominal pain (RAP) severe enough to interfere with their daily activities. No organic cause for this pain can be found on physical examination or investigation for the majority of such children. Although many children are managed by reassurance and simple measures, a large range of psychosocial interventions involving cognitive and behavioural components have been recommended.

OBJECTIVES

To determine the effectiveness of psychosocial interventions for reducing pain in school-aged children with RAP.

SEARCH METHODS

In June 2016 we searched CENTRAL, MEDLINE, Embase, eight other databases, and two trials registers. We also searched the references of identified studies and relevant reviews.

SELECTION CRITERIA

Randomised controlled trials comparing psychosocial therapies with usual care, active control, or wait-list control for children and adolescents (aged 5 to 18 years) with RAP or an abdominal pain-related functional gastrointestinal disorder defined by the Rome III criteria were eligible for inclusion.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Five review authors independently selected studies, assessed them for risk of bias, and extracted relevant data. We also assessed the quality of the evidence using the GRADE approach.

MAIN RESULTS

This review includes 18 randomised controlled trials (14 new to this version), reported in 26 papers, involving 928 children and adolescents with RAP between the ages of 6 and 18 years. The interventions were classified into four types of psychosocial therapy: cognitive behavioural therapy (CBT), hypnotherapy (including guided imagery), yoga, and written self-disclosure. The studies were carried out in the USA, Australia, Canada, the Netherlands, Germany, and Brazil. The majority of the studies were small and short term; only two studies included more than 100 participants, and only five studies had follow-up assessments beyond six months. Small sample sizes and the degree of assessed risk of performance and detection bias in many studies led to the overall quality of the evidence being rated as low to very low for all outcomes.For CBT compared to control, we found evidence of treatment success postintervention (odds ratio (OR) 5.67, 95% confidence interval (CI) 1.18 to 27.32; Z = 2.16; P = 0.03; 4 studies; 175 children; very low-quality evidence), but no evidence of treatment success at medium-term follow-up (OR 3.08, 95% CI 0.93 to 10.16; Z = 1.85; P = 0.06; 3 studies; 139 children; low-quality evidence) or long-term follow-up (OR 1.29, 95% CI 0.50 to 3.33; Z = 0.53; P = 0.60; 2 studies; 120 children; low-quality evidence). We found no evidence of effects of intervention on pain intensity scores measured postintervention (standardised mean difference (SMD) -0.33, 95% CI -0.74 to 0.08; 7 studies; 405 children; low-quality evidence), or at medium-term follow-up (SMD -0.32, 95% CI -0.85 to 0.20; 4 studies; 301 children; low-quality evidence).For hypnotherapy (including studies of guided imagery) compared to control, we found evidence of greater treatment success postintervention (OR 6.78, 95% CI 2.41 to 19.07; Z = 3.63; P = 0.0003; 4 studies; 146 children; low-quality evidence) as well as reductions in pain intensity (SMD -1.01, 95% CI -1.41 to -0.61; Z = 4.97; P < 0.00001; 4 studies; 146 children; low-quality evidence) and pain frequency (SMD -1.28, 95% CI -1.84 to -0.72; Z = 4.48; P < 0.00001; 4 studies; 146 children; low-quality evidence). The only study of long-term effect reported continued benefit of hypnotherapy compared to usual care after five years, with 68% reporting treatment success compared to 20% of controls (P = 0.005).For yoga therapy compared to control, we found no evidence of effectiveness on pain intensity reduction postintervention (SMD -0.31, 95% CI -0.67 to 0.05; Z = 1.69; P = 0.09; 3 studies; 122 children; low-quality evidence).The single study of written self-disclosure therapy reported no benefit for pain.There was no evidence of effect from the pooled analyses for any type of intervention on the secondary outcomes of school performance, social or psychological functioning, and quality of daily life.There were no adverse effects for any of the interventions reported.

AUTHORS' CONCLUSIONS

The data from trials to date provide some evidence for beneficial effects of CBT and hypnotherapy in reducing pain in the short term in children and adolescents presenting with RAP. There was no evidence for the effectiveness of yoga therapy or written self-disclosure therapy. There were insufficient data to explore effects of treatment by RAP subtype.Higher-quality, longer-duration trials are needed to fully investigate the effectiveness of psychosocial interventions. Identifying the active components of the interventions and establishing whether benefits are sustained in the long term are areas of priority. Future research studies would benefit from employing active control groups to help minimise potential bias from wait-list control designs and to help account for therapist and intervention time.

Non-pharmacological management of abdominal pain-related functional gastrointestinal disorders in children

BACKGROUND

Abdominal pain-related functional gastrointestinal disorder (AP-FGID) comprises of 4 main conditions: functional dyspepsia, irritable bowel syndrome, abdominal migraine and functional abdominal pain. AP-FGIDs are diagnosed clinically based on the Rome IV criteria for FGIDs of childhood. There is limited evidence for pharmacological therapies.

DATA SOURCES

This review article discusses nonpharmacological management of AP-FGID based on the current literature including systematic reviews, randomized controlled trials, cohort and case control studies. We aim to provide a comprehensive overview on the available evidence for the pediatricians and pediatric gastroenterologists involved in managing children with AP-FGID.

RESULTS

Managing AP-FGIDs can be challenging. This should follow a stepwise approach with focused history, identification of "red flag" signs and symptoms, physical examination and investigations done following initial consultation. Family needs explaining that there is nothing seriously wrong with the child's abdomen. This explanation and reassurance can achieve symptom control in large number of cases. Non-pharmacological interventions are delivered through lifestyle and dietary changes and bio-psychosocial therapies. Dietary interventions vary depending on the type of AP-FGID. Bio-psychosocial therapies such as hypnotherapy, cognitive behavioral therapy and yoga aim at stress reduction.

CONCLUSION

There is increasing evidence for use of non-pharmacological interventions in children with APFGID.

Recurrent abdominal pain in children: a clinical approach

The term 'recurrent abdominal pain', or RAP, refers mainly to the duration of painful period and frequency of pain. The commonly accepted duration is at least three months in the preceding period, and over this three-month period, there are at least three episodes of pain that are severe enough to affect the daily activities of the affected patients. Over the years, with advances in medical technology and better understanding of the pathophysiology of abdominal pain, more and more organic causes have been identified. However, the most common cause of RAP in children is still functional in origin.

Psychological interventions for parents of children and adolescents with chronic illness

BACKGROUND

Psychological therapies have been developed for parents of children and adolescents with a chronic illness. Such therapies include interventions directed at the parent only or at parent and child/adolescent, and are designed to improve parent, child, and family outcomes. This is an updated version of the original Cochrane review published in Issue 8, 2012, (Psychological interventions for parents of children and adolescents with chronic illness).

OBJECTIVES

To evaluate the efficacy of psychological therapies that include parents of children and adolescents with chronic illnesses including painful conditions, cancer, diabetes mellitus, asthma, traumatic brain injury (TBI), inflammatory bowel diseases (IBD), skin diseases, or gynaecological disorders. We also aimed to evaluate the adverse events related to implementation of psychological therapies for this population. Secondly, we aimed to evaluate the risk of bias of included studies and the quality of outcomes using the GRADE assessment.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and PsycINFO for randomised controlled trials (RCTs) of psychological interventions that included parents of children and adolescents with a chronic illness. Databases were searched to July 2014.

SELECTION CRITERIA

Included studies were RCTs of psychological interventions that delivered treatment to parents of children and adolescents with a chronic illness compared to an active control, waiting list, or treatment as usual control group.

DATA COLLECTION AND ANALYSIS

Study characteristics and outcomes were extracted from included studies. We analysed data using two categories. First, we analysed data by each individual medical condition collapsing across all treatment classes at two time points. Second, we analysed data by each individual treatment class; cognitive behavioural therapy (CBT), family therapy (FT), problem solving therapy (PST) and multisystemic therapy (MST) collapsing across all medical conditions. For both sets of analyses we looked immediately post-treatment and at the first available follow-up. We assessed treatment effectiveness for two primary outcomes: parent behaviour and parent mental health. Five secondary outcomes were extracted; child behaviour/disability, child mental health, child symptoms, family functioning, and adverse events. Risk of bias and quality of evidence were assessed.

MAIN RESULTS

Thirteen studies were added in this update, giving a total of 47 RCTs. The total number of participants included in the data analyses was 2985, 804 of whom were added to the analyses in the update. The mean age of the children was 14.6 years. Of the 47 RCTs, the studies focused on the following paediatric conditions: n = 14 painful conditions, n = 13 diabetes, n =10 cancer, n = 5 asthma, n = 4 TBI, and n = 1 atopic eczema. We did not identify any studies treating parents of children with gynaecological disorders or IBD. Risk of bias assessments of included studies were predominantly unclear. Evidence quality, assessed using the GRADE criteria, was judged to be of low or very low quality.Analyses of separate medical conditions, across all treatment types, revealed two beneficial effects of psychological therapies for our primary outcomes. First, psychological therapies led to improved adaptive parenting behaviour in parents of children with cancer post-treatment (standardised mean difference (SMD) -0.20, 95% confidence interval (CI) -0.36 to -0.04, Z = 2.44, p = 0.01). In addition, therapies also improved parent mental health at follow-up in this group (SMD = -0.18, 95% CI -0.32 to -0.04, Z = 2.58, p = 0.01). We did not find any effect of therapies for parent behaviour for parents of children with a painful condition post-treatment or at follow-up, or for parent mental health for parents of children with cancer, diabetes, asthma, or TBI post-treatment. For all other primary outcomes, no analysis could be conducted due to lack of data.Across all medical conditions, three effects were found for the primary outcomes of psychological therapies. PST had a beneficial effect on parent adaptive behaviour (SMD = -0.25, 95% CI -0.39 to -0.11, Z = 3.59, p < 0.01) and parent mental health (SMD= -0.24, 95% CI -0.42 to -0.05, Z = 2.50, p = 0.01) immediately post-treatment and this effect was maintained at follow-up for parent mental health (SMD= -0.19, 95% CI -0.34 to -0.04, Z = 2.55, p = 0.01). The remaining analysis for PST on parent behaviour found no effect. No effects were found for CBT post-treatment or at follow-up for either parent outcome. For FT, only one analysis could be run on parent mental health and no effect was found. Due to lack of data, the remaining analyses of primary outcomes could not be run. For MST, no parent outcomes could be analysed due to lack of data.Secondary outcome analyses are presented in the Results section. Five studies reported that there were no adverse events during the trial. The remaining 42 studies did not report adverse events.

AUTHORS' CONCLUSIONS

This update includes 13 additional studies, although our conclusions have not changed from the original version. There is little evidence for the efficacy of psychological therapies that include parents on most outcome domains of functioning, for a large number of common chronic illnesses in children. However, psychological therapies are efficacious for some outcomes. CBT that includes parents is beneficial for reducing children's primary symptoms, and PST that includes parents improved parent adaptive behaviour and parent mental health. There is evidence that the beneficial effects can be maintained at follow-up for diabetes-related symptoms in children, and for the mental health of parents of children with cancer and parents who received PST.

Stop the pain: study protocol for a randomized-controlled trial

BACKGROUND

Functional abdominal pain (FAP) is not only a highly prevalent disease but also poses a considerable burden on children and their families. Untreated, FAP is highly persistent until adulthood, also leading to an increased risk of psychiatric disorders. Intervention studies underscore the efficacy of cognitive behavioral treatment approaches but are limited in terms of sample size, long-term follow-up data, controls and inclusion of psychosocial outcome data.

METHODS/DESIGN

In a multicenter randomized controlled trial, 112 children aged 7 to 12 years who fulfill the Rome III criteria for FAP will be allocated to an established cognitive behavioral training program for children with FAP (n = 56) or to an active control group (focusing on age-appropriate information delivery; n = 56). Randomization occurs centrally, blockwise and is stratified by center. This study is performed in five pediatric gastroenterology outpatient departments. Observer-blind assessments of outcome variables take place four times: pre-, post-, 3- and 12-months post-treatment. Primary outcome is the course of pain intensity and frequency. Secondary endpoints are health-related quality of life, pain-related coping and cognitions, as well as self-efficacy.

DISCUSSION

This confirmatory randomized controlled clinical trial evaluates the efficacy of a cognitive behavioral intervention for children with FAP. By applying an active control group, time and attention processes can be controlled, and long-term follow-up data over the course of one year can be explored.

TRIAL REGISTRATION

Paediatricians' perceptions of a potential online psychosocial intervention for children with recurrent abdominal pain

AIMS

To evaluate paediatricians' perceived effectiveness of an online psychosocial intervention for children with recurrent abdominal pain (RAP). Also, to explore which elements of this intervention they would consider necessary when applied in the clinical context.

METHODS

A total of 131 paediatricians affiliated to Catalan and Balearic paediatric societies completed an online survey about how effective they would perceive an online psychosocial intervention for RAP (for reducing pain intensity, reducing disability and preventing chronicity) and how this intervention should be carried out. They were asked about the perceived effectiveness of the standard medical treatments they routinely applied for RAP and also their opinion of face-to-face psychosocial interventions.

RESULTS

A face-to face psychosocial intervention was considered better (to reduce pain intensity, reduce disability and prevent chronic pain) than an online psychological intervention and the standard medical treatment. Online and face-to-face psychosocial interventions are considered equally useful for children with mild disability, but a face-to-face psychosocial intervention is considered better for those with moderate and severe levels of disability. Paediatricians considered that an online psychosocial intervention for children with RAP should be simple and consistent; it should provide easy access for users; and its interface should be easy to use and attractive.

CONCLUSIONS

Paediatricians show a positive attitude towards a potential online psychosocial intervention for children and adolescents with RAP. However, they do not use the Internet for offering health care, and they would prefer a face-to-face psychosocial intervention.

Irritable bowel syndrome in children: pathogenesis, diagnosis and evidence-based treatment

Irritable bowel syndrome (IBS) is the commonest cause of recurrent abdominal pain (RAP) in children in both more developed and developing parts of the world. It is defined by the Rome III criteria for functional gastrointestinal disorders. It is characterized by abdominal pain that is improved by defecation and whose onset is associated with a change in stool form and or frequency and is not explained by structural or biochemical abnormalities. It is estimated that 10%-15% of older children and adolescents suffer from IBS. IBS can be considered to be a brain-gut disorder possibly due to complex interaction between environmental and hereditary factors. The diagnosis of IBS is made based on the Rome III criteria together with ruling out organic causes of RAP in children such as inflammatory bowel disease and celiac disease. Once the diagnosis of IBS is made, it is important to explain to the parents (and children) that there is no serious underlying disease. This reassurance may be effective treatment in a large number of cases. Lifestyle modifications, stress management, dietary interventions and probiotics may be beneficial in some cases. Although there is limited evidence for efficacy of pharmacological therapies such as antispasmodics and antidiarrheals; these have a role in severe cases. Biopsychosocial therapies have shown encouraging results in initial trials but are beset by limited availability. Further research is necessary to understand the pathophysiology and provide specific focused therapies.

Psychological therapies for the management of chronic and recurrent pain in children and adolescents

BACKGROUND

This is an update of the original Cochrane review first published in Issue 1, 2003, and previously updated in 2009 and 2012. Chronic pain affects many children, who report severe pain, disability, and distressed mood. Psychological therapies are emerging as effective interventions to treat children with chronic or recurrent pain. This update focuses specifically on psychological therapies delivered face-to-face, adds new randomised controlled trials (RCTs), and additional data from previously included trials.

OBJECTIVES

There were three objectives to this review. First, to determine the effectiveness on clinical outcomes of pain severity, disability, depression, and anxiety of psychological therapy delivered face-to-face for chronic and recurrent pain in children and adolescents compared with active treatment, waiting-list, or standard medical care. Second, to evaluate the impact of psychological therapies on depression and anxiety, which were previously combined as 'mood'. Third, we assessed the risk of bias of the included studies and the quality of outcomes using the GRADE criteria.

SEARCH METHODS

Searches were undertaken of CENTRAL, MEDLINE, EMBASE, and PsycINFO. We searched for further RCTs in the references of all identified studies, meta-analyses, and reviews. Trial registry databases were also searched. The date of most recent search was January 2014.

SELECTION CRITERIA

RCTs with at least 10 participants in each arm post-treatment comparing psychological therapies with active treatment, standard medical care, or waiting-list control for children or adolescents with episodic, recurrent or persistent pain were eligible for inclusion. Only trials conducted in person (face-to-face) were considered. Studies that delivered treatment remotely were excluded from this update.

DATA COLLECTION AND ANALYSIS

All included studies were analysed and the quality of outcomes were assessed. All treatments were combined into one class, psychological treatments. Pain conditions were split into headache and non-headache. Both conditions were assessed on four outcomes: pain, disability, depression, and anxiety. Data were extracted at two time points; post-treatment (immediately or the earliest data available following end of treatment) and at follow-up (between three and 12 months post-treatment).

MAIN RESULTS

Seven papers were identified in the updated search. Of these papers, five presented new trials and two presented follow-up data for previously included trials. Five studies that were previously included in this review were excluded as therapy was delivered remotely. The review thus included a total of 37 studies. The total number of participants completing treatments was 2111. Twenty studies addressed treatments for headache (including migraine); nine for abdominal pain; two for mixed pain conditions including headache pain, two for fibromyalgia, two for recurrent abdominal pain or irritable bowel syndrome, and two for pain associated with sickle cell disease.Analyses revealed psychological therapies to be beneficial for children with chronic pain on seven outcomes. For headache pain, psychological therapies reduced pain post-treatment and at follow-up respectively (risk ratio (RR) 2.47, 95% confidence interval (CI) 1.97 to 3.09, z = 7.87, p < 0.01, number needed to treat to benefit (NNTB) = 2.94; RR 2.89, 95% CI 1.03 to 8.07, z = 2.02, p < 0.05, NNTB = 3.67). Psychological therapies also had a small beneficial effect at reducing disability in headache conditions post-treatment and at follow-up respectively (standardised mean difference (SMD) -0.49, 95% CI -0.74 to -0.24, z = 3.90, p < 0.01; SMD -0.46, 95% CI -0.78 to -0.13, z = 2.72, p < 0.01). No beneficial effect was found on depression post-treatment (SMD -0.18, 95% CI -0.49 to 0.14, z = 1.11, p > 0.05). At follow-up, only one study was eligible, therefore no analysis was possible and no conclusions can be drawn. Analyses revealed a small beneficial effect for anxiety post-treatment (SMD -0.33, 95% CI -0.61 to -0.04, z = 2.25, p < 0.05). However, this was not maintained at follow-up (SMD -0.28, 95% CI -1.00 to 0.45; z = 0.75, p > 0.05).Analyses revealed two beneficial effects of psychological treatment for children with non-headache pain. Pain was found to improve post-treatment (SMD -0.57, 95% CI -0.86 to -0.27, z = 3.74, p < 0.01), but not at follow-up (SMD -0.11, 95% CI -0.41 to 0.19, z = 0.73, p > 0.05). Psychological therapies also had a beneficial effect for disability post-treatment (SMD -0.45, 95% CI -0.71 to -0.19, z = 3.40, p < 0.01), but this was not maintained at follow-up (SMD -0.35, 95% CI -0.71 to 0.02, z = 1.87, p > 0.05). No effect was found for depression or anxiety post-treatment (SMD -0.07, 95% CI -0.30 to 0.17, z = 0.54, p > 0.05; SMD -0.15, 95% CI -0.36 to 0.07, z = 1.33, p > 0.05) or at follow-up (SMD 0.06, 95% CI -0.16 to 0.28, z = 0.53, p > 0.05; SMD 0.05, 95% CI -0.24 to 0.33, z = 0.32, p > 0.05).

AUTHORS' CONCLUSIONS

Psychological treatments delivered face-to-face are effective in reducing pain intensity and disability for children and adolescents (<18 years) with headache, and therapeutic gains appear to be maintained, although this should be treated with caution for the disability outcome as only two studies could be included in the follow-up analysis. Psychological therapies are also beneficial at reducing anxiety post-treatment for headache. For non-headache conditions, psychological treatments were found to be beneficial for pain and disability post-treatment but these effects were not maintained at follow-up. There is limited evidence available to estimate the effects of psychological therapies on depression and anxiety for children and adolescents with headache and non-headache pain. The conclusions of this update replicate and add to those of the previous review which found that psychological therapies were effective in reducing pain intensity for children with headache and non-headache pain conditions, and these effects were maintained at follow-up for children with headache conditions.

Brief hypnotherapeutic-behavioral intervention for functional abdominal pain and irritable bowel syndrome in childhood: a randomized controlled trial

Functional abdominal pain and irritable bowel syndrome are two prevalent disorders in childhood which are associated with recurrent or chronic abdominal pain, disabilities in daily functioning, and reduced quality of life. This study aimed to evaluate a brief hypnotherapeutic-behavioral intervention program in a prospective randomized controlled design. Thirty-eight children, 6 to 12 years of age, and their parents were randomly assigned to a standardized hypnotherapeutic-behavioral treatment (n = 20) or to a waiting list condition (n = 18). Both groups were reassessed 3 months after beginning. Primary outcome variables were child-completed pain measures and pain-related disability. Secondary outcome variables were parent-completed measures of their children's pain and pain-related disability. Health-related quality of life from both perspectives also served as a secondary outcome. In the treatment group, 11 of 20 children (55.0%) showed clinical remission (>80% improvement), whereas only one child (5.6%) in the waiting list condition was classified as responder. Children in the treatment group reported a significantly greater reduction of pain scores and pain-related disability than children of the waiting list condition. Parental ratings also showed a greater reduction of children's abdominal pain and pain-related disability. Health-related quality of life did not increase significantly.

CONCLUSIONS

Hypnotherapeutic and behavioral interventions are effective in treating children with long-standing AP. Treatment success of this brief program should be further evaluated against active interventions with a longer follow-up.

Prognosis of abdominal pain in children in primary care--a prospective cohort study

PURPOSE

Abdominal pain is a common complaint in children. Because few data exist on its natural history, we wanted to investigate the prognosis of abdominal pain in children in general practice.

METHODS

In a prospective cohort study of children (aged 4 to 17 years) complaining of abdominal pain, follow-up was at 3, 6, 9, and 12 months using standardized questionnaires. The primary outcome measure was chronic abdominal pain: abdominal pain at least 1 time a month during at least 3 consecutive months that had an impact on daily activities. Prevalence, incidence, and duration of chronic abdominal pain were assessed.

RESULTS

Three hundred five children (116 boys, 189 girls), with a median age of 7.8 years (interquartile range [IQR] = 5.7-10.5 years) were included. Chronic abdominal pain was present in 142 (46.6%) children at an initial visit to the primary care physician for this complaint. During follow-up, 78.7% fulfilled the criteria for chronic abdominal pain at 1 or more follow-up points. Among 163 children at risk for developing chronic abdominal pain, the cumulative incidence of chronic abdominal pain was 60.1% (95% CI, 52.1%-67.7%) and was higher in girls than in boys (RR = 1.23; 95% CI, 0.94-1.61). Median duration of abdominal pain was 7.5 months (IQR = 4.5-12.0 months). Children aged 10 to 17 years had the longest duration of abdominal pain (median = 9.0 months; IQR = 7.5-12.4 months). Children with symptoms of irritable bowel syndrome seemed to have a less favorable prognosis compared with children with symptoms of functional dyspepsia or functional abdominal pain.

CONCLUSIONS

The presence and development of chronic abdominal pain is common and of long duration among children consulting in primary care for abdominal pain. These poor outcome data warrant follow-up.

[Therapy of functional abdominal pain in childhood. Concept, acceptance and preliminary results of a short hypnotherapeutic-behavioural intervention]

OBJECTIVE

Recurrent abdominal pain is one of the most frequent pain syndromes in childhood and is accompanied by notable functional impairment and unfavourable long-term outcome. Psychotherapeutic approaches are promising, but not widely used in Germany. The concept of a multimodal short-term intervention and its acceptance are described and preliminary results are reported.

METHOD

A total of 21 children aged 6-12 years and their parents participated in a hypnotherapeutic-behavioural short intervention program. Preliminary results on efficacy up to 3 months are reported.

RESULTS

Participating children showed a decrease in pain frequency and daily impairment. Health-related quality of life also increased and associated mental problems could be reduced. Content and conditions of the intervention were rated as helpful by children and parents.

CONCLUSION

Preliminary results indicate that even short psychotherapeutic interventions might help affected children effectively and lower the burden felt by parents. Further investigations using a randomized controlled trial design and focussing on children suffering more severely should follow to allow major conclusions.

Psychological therapies for the management of chronic and recurrent pain in children and adolescents

BACKGROUND

Chronic pain affects many children, who report severe pain, distressed mood, and disability. Psychological therapies are emerging as effective interventions to treat children with chronic or recurrent pain. This update adds recently published randomised controlled trials (RCTs) to the review published in 2009.

OBJECTIVES

To assess the effectiveness of psychological therapies, principally cognitive behavioural therapy and behavioural therapy, for reducing pain, disability, and improving mood in children and adolescents with recurrent, episodic, or persistent pain. We also assessed the risk of bias and methodological quality of the included studies.

SEARCH METHODS

Searches were undertaken of MEDLINE, EMBASE, and PsycLIT. We searched for RCTs in references of all identified studies, meta-analyses and reviews. Date of most recent search: March 2012.

SELECTION CRITERIA

RCTs with at least 10 participants in each arm post-treatment comparing psychological therapies with active treatment were eligible for inclusion (waiting list or standard medical care) for children or adolescents with episodic, recurrent or persistent pain.

DATA COLLECTION AND ANALYSIS

All included studies were analysed and the quality of the studies recorded. All treatments were combined into one class: psychological treatments; headache and non-headache outcomes were separately analysed on three outcomes: pain, disability, and mood. Data were extracted at two time points; post-treatment (immediately or the earliest data available following end of treatment) and at follow-up (at least three months after the post-treatment assessment point, but not more than 12 months).

MAIN RESULTS

Eight studies were added in this update of the review, giving a total of 37 studies. The total number of participants completing treatments was 1938. Twenty-one studies addressed treatments for headache (including migraine); seven for abdominal pain; four included mixed pain conditions including headache pain, two for fibromyalgia, two for pain associated with sickle cell disease, and one for juvenile idiopathic arthritis. Analyses revealed five significant effects. Pain was found to improve for headache and non-headache groups at post-treatment, and for the headache group at follow-up. Mood significantly improved for the headache group at follow-up, although, this should be interpreted with caution as there were only two small studies entered into the analysis. Finally, disability significantly improved in the non-headache group at post-treatment. There were no other significant effects.

AUTHORS' CONCLUSIONS

Psychological treatments are effective in reducing pain intensity for children and adolescents (<18 years) with headache and benefits from therapy appear to be maintained. Psychological treatments also improve pain and disability for children with non-headache pain. There is limited evidence available to estimate the effects of psychological therapies on mood for children and adolescents with headache and non-headache pain. There is also limited evidence to estimate the effects on disability in children with headache. These conclusions replicate and add to those of the previous review which found psychological therapies were effective in reducing pain intensity for children with headache and non-headache pain conditions, and these effects were maintained at follow-up.

Psychological interventions for parents of children and adolescents with chronic illness

BACKGROUND

Psychological therapies have been developed for parents of children and adolescents with a chronic illness. Such therapies include parent only or parent and child/adolescent, and are designed to treat parent behaviour, parent mental health, child behaviour/disability, child mental health, child symptoms and/or family functioning. No comprehensive, meta-analytic reviews have been published in this area.

OBJECTIVES

To evaluate the effectiveness of psychological therapies that include coping strategies for parents of children/adolescents with chronic illnesses (painful conditions, cancer, diabetes mellitus, asthma, traumatic brain injury, inflammatory bowel diseases, skin diseases or gynaecological disorders). The therapy will aim to improve parent behaviour, parent mental health, child behaviour/disability, child mental health, child symptoms and family functioning.

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE and PsycINFO for randomised controlled trials (RCTs) of psychological interventions that included parents of children and adolescents with a chronic illness. The initial search was from inception of these databases to June 2011 and we conducted a follow-up search from June 2011 to March 2012. We identified additional studies from the reference list of retrieved papers and from discussion with investigators.

SELECTION CRITERIA

Included studies were RCTs of psychological interventions that delivered treatment to parents of children and adolescents (under 19 years of age) with a chronic illness compared to active control, wait list control or treatment as usual. We excluded studies if the parent component was a coaching intervention, the aim of the intervention was health prevention/promotion, the comparator was a pharmacological treatment, the child/adolescent had an illness not listed above or the study included children with more than one type of chronic illness. Further to this, we excluded studies when the sample size of either comparator group was fewer than 10 at post-treatment.

DATA COLLECTION AND ANALYSIS

We included 35 RCTs involving a total of 2723 primary trial participants. Two review authors extracted data from 26 studies. We analysed data using two categories. First, we analysed data by each medical condition across all treatment classes at two time points (immediately post-treatment and the first available follow-up). Second, we analysed data by each treatment class (cognitive behavioural therapy (CBT), family therapy (FT), problem solving therapy (PST) and multisystemic therapy (MST)) across all medical conditions at two time points (immediately post-treatment and the first available follow-up). We assessed treatment effectiveness on six possible outcomes: parent behaviour, parent mental health, child behaviour/disability, child mental health, child symptoms and family functioning.

MAIN RESULTS

Across all treatment types, psychological therapies that included parents significantly improved child symptoms for painful conditions immediately post-treatment. Across all medical conditions, cognitive behavioural therapy (CBT) significantly improved child symptoms and problem solving therapy significantly improved parent behaviour and parent mental health immediately post-treatment. There were no other effects at post-treatment or follow-up. The risk of bias of included studies is described.

AUTHORS' CONCLUSIONS

There is no evidence on the effectiveness of psychological therapies that include parents in most outcome domains of functioning, for a large number of common chronic illnesses in children. There is good evidence for the effectiveness of including parents in psychological therapies that reduce pain in children with painful conditions. There is also good evidence for the effectiveness of CBT that includes parents for improving the primary symptom complaints when available data were included from chronic illness conditions. Finally, there is good evidence for the effectiveness of problem solving therapy delivered to parents on improving parent problem solving skills and parent mental health. All effects are immediately post-treatment. There are no significant findings for any treatment effects in any condition at follow-up.

Cognitive Behavioral Therapy for Pediatric Chronic Pain: The Problem, Research, and Practice

The purpose of this article is to outline the rationale and use of cognitive behavioral therapy (CBT) for the treatment of pediatric chronic pain. The article begins by demonstrating the scope and impact of the problem of pediatric chronic pain.

Antidepressants for the treatment of abdominal pain-related functional gastrointestinal disorders in children and adolescents

BACKGROUND

Abdominal pain-related functional gastrointestinal disorders (FGIDs) are among the most common medical problems in paediatric medicine. Frequently, physicians prescribe antidepressants as a second-line treatment for children and adolescents with FGIDs. To date, the evidence on the benefits and harms of antidepressants for the treatment of abdominal pain-related FGIDs has not been assessed systematically.

OBJECTIVES

The primary objectives were to conduct a systematic review to evaluate the efficacy and safety of antidepressants for the treatment of abdominal pain-related FGIDs in children and adolescents.

SEARCH STRATEGY

We searched The Cochrane Library, PubMed, EMBASE, IPA, CINAHL, PsycINFO, ISI Web of Science, Biosis Previews and the International Clinical Trials Registry Platform of the World Health Organization with appropriate filters (from inception to January 31, 2011).

SELECTION CRITERIA

For efficacy we included double-blind, randomised controlled trials (RCTs) of antidepressants for treatment of abdominal pain-related FGIDs in children and adolescents 18 years or younger. Open-label and uncontrolled experimental studies, as well as observational studies were eligible for the assessment of harms. The minimum study duration was 4 weeks. The minimum study size was 30 participants.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed all abstracts and full text articles, and rated the risk of bias for included studies. Data were extracted independently by one author and checked for accuracy by another author. Data were analysed using RevMan 5.

MAIN RESULTS

Two RCTs (123 participants), both using amitriptyline, met the pre-specified inclusion criteria. These studies provided mixed findings on the efficacy of amitriptyline for the treatment of abdominal pain-related FGIDs. The larger, publicly-funded study reported no statistically significant difference in efficacy between amitriptyline and placebo in 90 children and adolescents with FGIDs after 4 weeks of treatment. On intention-to-treat (ITT)- analysis, 59% of the children reported feeling better in the amitriptyline group compared with 53% in the placebo group (RR 1.12; 95% CI: 0.77 to 1.63; P = 0.54). The risk of bias for this study was rated as low.The second RCT enrolled 33 adolescents with irritable bowel syndrome. Patients receiving amitriptyline experienced greater improvements in the primary outcome, overall quality of life, at weeks 6, 10, and 13 compared with those on placebo (P= 0.019, 0.004, and 0.013, respectively). No effect estimates were calculated for the quality of life outcome because mean quality of life scores and standard deviations were not reported. For most secondary outcomes no statistically significant differences between amitriptyline and placebo could be detected. The risk of bias for this study was rated as unclear for most items. However, it was rated as high for other bias due to multiple testing. The results of this study should be interpreted with caution due to the small number of patients and multiple testing.The larger study reported mild adverse events including fatigue, rash and headache and dizziness. On ITT analysis, 4% of the amitriptyline group experienced at least one adverse event compared to 2% of the placebo group. There was no statistically significant difference in the proportion of patients who experienced at least one adverse event (RR 1.91; 95% CI 0.18 to 20.35; P = 0.59). The smaller study reported no adverse events. The methods of adverse effects assessment was poorly reported in both studies and no clear conclusions on the risks of harms of amitriptyline can be drawn.

AUTHORS' CONCLUSIONS

Clinicians must be aware that for the majority of antidepressant medications no evidence exists that supports their use for the treatment of abdominal pain-related FGIDs in children and adolescents. The existing randomised controlled evidence is limited to studies on amitriptyline and revealed no statistically significant differences between amitriptyline and placebo for most efficacy outcomes. Amitriptyline does not appear to provide any benefit for the treatment of FGIDs in children and adolescents. Studies in children with depressive disorders have shown that antidepressants can lead to substantial, sometimes life-threatening adverse effects. Until better evidence evolves, clinicians should weigh the potential benefits of antidepressant treatment against known risks of antidepressants in paediatric patients.

Childhood nonspecific abdominal pain in family practice: incidence, associated factors, and management

PURPOSE

Nonspecific abdominal pain (NSAP) is a common complaint in childhood. In specialist care, childhood NSAP is considered to be a complex and time-consuming problem, and parents are hard to reassure. Little is known about NSAP in family practice, but the impression is that family physicians consider it to be a benign syndrome needing little more than reassurance. This discrepancy calls for a better understanding of NSAP in family practice.

METHODS

Data were obtained from the Second Dutch National Survey of General Practice (2001). Using registration data of 91 family practices, we identified children aged 4 to 17 years with NSAP. We calculated the incidence, and we studied factors associated with childhood NSAP, referrals, and prescriptions.

RESULTS

The incidence of NSAP was 25.0 (95% confidence interval [CI], 23.7-26.3) per 1,000 person years. Most children (92.7%) with newly diagnosed NSAP (N = 1,480) consulted their doctor for this condition once or twice. Factors independently associated with NSAP were female sex (odds ratio [OR] = 1.4; 95% CI, 1.3-1.5), nongastrointestinal-nonspecific somatic symptoms (OR = 1.3; 95% CI, 1.1-1.5), and health care use (OR = 1.04; 95% CI, 1.03-1.05). When NSAP was diagnosed at the first visit, 3% of the patients were referred to specialist care, and 1% received additional testing. Family physicians prescribed medication in 21.3% of the visits for NSAP.

CONCLUSIONS

Childhood NSAP is a common problem in family practice. Most patients visit their doctor once or twice for this problem. Family physicians use little additional testing and make few referrals in their management of childhood NSAP. Despite the lack of evidence for effectiveness, family physicians commonly prescribe medication for NSAP.

Cognitive-behavioral treatment of persistent functional somatic complaints and pediatric anxiety: an initial controlled trial

BACKGROUND

Children and adolescents who seek medical treatment for persistent physical distress often suffer from co-occurring anxiety disorders. Treatment options for this impaired population are limited. This study tests the feasibility and potential efficacy of a cognitive-behavioral intervention targeting pain and anxiety for youth with impairing functional physical symptoms and anxiety disorders presenting to pediatricians for medical care.

METHODS

Children and adolescents (aged 8-16) experiencing somatic complaints, without an explanatory medical disorder (i.e., functional), were recruited from primary care and specialty (gastroenterologists and cardiologists) pediatricians. Forty children, primarily with gastrointestinal symptoms, who met criteria for a co-occurring anxiety disorder, were randomly assigned to a cognitive-behavioral treatment addressing pain and anxiety, Treatment of Anxiety and Physical Symptoms (TAPS), or to a waiting list control.

RESULTS

TAPS was found to be an acceptable treatment for this population and was superior to the waiting list condition. Eighty percent of children in TAPS were rated as treatment responders by independent evaluators compared with none of the controls. Overall, self- and parent ratings indicated reductions in children's somatic discomfort and anxiety following intervention. TAPS participants maintained clinical gains 3 months following treatment.

CONCLUSIONS

The study supports the feasibility and preliminary efficacy of a cognitive-behavioral intervention targeting co-occurring physical distress and anxiety in youth presenting for medical treatment. Such an approach has the potential to exert broad impact on children's dysfunction and to minimize exposure to invasive, ineffective, and costly medical procedures and treatments.

Recurrent abdominal pain in childhood

BACKGROUND

Chronic, recurrent abdominal pain is common among children and adolescents. It interferes with everyday life, causes absence from school, and leads to frequent medical consultations, often involving burdensome diagnostic testing and protracted attempts at treatment.

METHOD

Selective review of the literature.

RESULTS

Organic causes should be ruled out with a thorough medical history and physical examination and a small number of laboratory tests. The pediatric Rome III criteria include valid diagnostic criteria for functional abdominal pain in childhood. The available data imply that this condition is best treated with cognitive behavioral therapy, rather than with medications or dietary measures.

CONCLUSION

A systematic approach to chronic recurrent abdominal pain in children and adolescents is key to ruling out organic diseases while avoiding unnecessary tests and treatments.

Recurrent abdominal pain in children and adolescents - a survey among paediatricians

Objective: Little is known about prevalence and usual treatment of childhood and adolescent recurrent abdominal pain (RAP) in outpatient paediatricians’ practice. This study’s primary objective was to acquire insights into the usual paediatricians’ treatment and their estimation of prevalence, age and gender of RAP patients. Further objectives were to assess to which extent family members of patients report similar symptoms, how paediatricians rate the strain of parents of affected children and adolescents and how paediatricians estimate the demand for psychological support.

Methods: Provided by a medical register, 437 outpatient paediatricians received a questionnaire to assess their perception of several psychosomatic problems and disorders including recurrent abdominal pain.

Results: According to paediatricians’ estimation, 15% of all visits are caused by patients with RAP. In 22% of these cases of RAP, at least one family member has similar problems. In about 15% of all RAP cases, parents ask for professional psychological support concerning their children’s issues, whereas 40% of paediatricians wish for psychological support considering this group of patients.

Conclusions: Estimated frequencies and paediatricians’ demands show the need for evidence-based psychological interventions in RAP to support usual medical treatment.

Restoration of vagal tone: a possible mechanism for functional abdominal pain

Functional abdominal pain (FAP) causes disruption of daily activities/missed school days, over utilization of healthcare, unnecessary surgeries, and anxiety in 10-15% of children. Its etiology is not clearly understood, however the success of several clinical protocols suggests that autonomic dysregulation is a factor. In this study autonomic activity, including heart rate variability (HRV), was compared between children with FAP and a comparison group. Twenty children with FAP and 10 children without FAP between the ages of 5 and 17 years old were compared on autonomic regulation using an ambulatory system at baseline and 8 weeks later. Children with FAP participated in 6 sessions of HRV biofeedback aimed at normalizing autonomic balance. At baseline, children with FAP appear to have more autonomic dysregulation than children without FAP. After completing HRV biofeedback, the FAP group was able to significantly reduce their symptoms in relation to significantly increasing their autonomic balance. In a sample of children with FAP, it appears that HRV biofeedback treatment improved their symptoms and that a change in vagal tone was a potential mediator for this improvement. The present study appears to point to excessive vagal withdrawal as an underlying mechanism of FAP.

Management of functional abdominal pain and irritable bowel syndrome in children and adolescents

Functional abdominal pain (FAP) and irritable bowel syndrome (IBS) are among the most commonly diagnosed medical problems in pediatrics. Symptom-based Rome III criteria for FAP and IBS have been validated and help the clinician in making a positive diagnosis. The majority of patients with mild complaints improve with reassurance and time. For a distinct subset of patients with more severe and disabling illness, finding effective treatment for these disorders remains a challenge. Over the years, a wide range of therapies have been proposed and studied. The lack of a single, proven intervention highlights the complex interplay of biopsychosocial factors probably involved in the development of childhood FAP and IBS, and the need for a multidisciplinary, integrated approach. This article reviews the current literature on the efficacy of pharmacologic, dietary and psychosocial interventions for FAP and IBS in children and adolescents.

Audio-recorded guided imagery treatment reduces functional abdominal pain in children: a pilot study

OBJECTIVE

This study was designed to develop and to test a home-based, guided imagery treatment protocol, using audio and video recordings, that is easy for health care professionals and patients to use, is inexpensive, and is applicable to a wide range of health care settings.

METHODS

Thirty-four children, 6 to 15 years of age, with a physician diagnosis of functional abdominal pain were assigned randomly to receive 2 months of standard medical care with or without home-based, guided imagery treatment. Children who received only standard medical care initially received guided imagery treatment after 2 months. Children were monitored for 6 months after completion of guided imagery treatment.

RESULTS

All treatment materials were reported to be self-explanatory, enjoyable, and easy to understand and to use. The compliance rate was 98.5%. In an intention-to-treat analysis, 63.1% of children in the guided imagery treatment group were treatment responders, compared with 26.7% in the standard medical care-only group (P = .03; number needed to treat: 3). Per-protocol analysis showed similar results (73.3% vs 28.6% responders). When the children in the standard medical care group also received guided imagery treatment, 61.5% became treatment responders. Treatment effects were maintained for 6 months (62.5% responders).

CONCLUSION

Guided imagery treatment plus medical care was superior to standard medical care only for the treatment of abdominal pain, and treatment effects were sustained over a long period.

Functional gastrointestinal disorders: past and present

BACKGROUND

Chronic abdominal pain is a common complaint in childhood and adolescence. Despite decades of clinical observations and research, it still poses a challenge to pediatric health care professionals. The aim of this review is to highlight the epidemiology of pediatric chronic abdominal pain and to describe the pathogenesis of this disorder, its clinical manifestations, evaluation and therapeutic options.

DATA SOURCES

Articles on chronic abdominal pain in the recent years from PubMed, MEDLINE, and reference textbooks were reviewed.

RESULTS

Chronic abdominal pain, a functional gastrointestinal disorder (FGID), is a multifactorial condition that results from a complex interaction between psychosocial and physiologic factors via the brain-gut axis. A thorough history coupled with a complete physical examination and normal screening studies rule out an organic cause in 95% of the cases. It is highly important for the physician to establish a trusting relationship with the child and parents because successful treatment including modification of physical and psychological stress factors, dietary changes, and drug therapy depends greatly on education, reassurance and active psychological support.

CONCLUSIONS

FGIDs are a cause of great anxiety, distress and morbidity in children as well as adults. As our understanding of these conditions improves, our therapeutic interventions will progress not only to overcome them but also to intervene early in the disease course so as to limit long-term impact.

[Functional abdominal pain in childhood]

Functional abdominal pain is one of the most common types of recurrent pediatric pain. This paper gives an overview of the etiopathogenesis, diagnostic criteria, and cognitive-behavioral intervention strategies for functional abdominal pain. It addresses the issues of organic causes, psychosocial stressors, and family and social conditions, as well as operant processes.
