Clinical features and risk factors for upper gastrointestinal bleeding in children: a case-crossover study

Gastrointestinal bleeding in children: diagnostic approach

Different conditions may underlie gastrointestinal bleeding (GIB) in children. The estimated prevalence of GIB in children is 6.4%, with spontaneous resolution in approximately 80% of cases. Nonetheless, the initial approach plays a pivotal role in determining the prognosis. The priority is the stabilization of hemodynamic status, followed by a systematic diagnostic approach. GIB can originate from either upper or lower gastrointestinal tract, leading to a broad differential diagnosis in infants and children. This includes benign and self-limiting disorders, alongside serious conditions necessitating immediate treatment. We performed a nonsystematic review of the literature, in order to describe the variety of conditions responsible for GIB in pediatric patients and to outline diagnostic pathways according to patients' age, suspected site of bleeding and type of bleeding which can help pediatricians in clinical practice. Diagnostic modalities may include esophagogastroduodenoscopy and colonoscopy, abdominal ultrasonography or computed tomography and, when necessary, magnetic resonance imaging. In this review, we critically assess these procedures, emphasizing their respective advantages and limitations concerning specific clinical scenarios.

Upper gastrointestinal bleeding in Bangladeshi children: Analysis of 100 cases

BACKGROUND

Upper gastrointestinal bleeding (UGIB) is defined as bleeding that occurs proximal to the ligament of Treitz and can sometimes lead to potentially serious and life-threatening clinical situations in children. Globally, the cause of UGIB differs significantly depending on the geographic location, patient population and presence of comorbid conditions.

AIM

To observe endoscopic findings of UGIB in children at a tertiary care center of Bangladesh.

METHODS

This retrospective study was carried out in the department of Pediatric Gastroenterology and Nutrition of Bangabandhu Shiekh Mujib Medical University, a tertiary care hospital of Bangladesh, between January 2017 and January 2019. Data collected from hospital records of 100 children who were 16 years of age or younger, came with hematemesis, melena or both hematemesis and melena. All patients underwent upper gastrointestinal endoscopy (Olympus CV 1000 upper gastrointestinal video endoscope) after initial stabilization. Necessary investigations to diagnose portal hypertension and chronic liver disease with underlying causes for management purposes were also done.

RESULTS

A total of 100 patients were studied. UGIB was common in the age group 5-10 years (42%), followed by above 10 years (37%). Hematemesis was the most common presenting symptom (75%) followed by both hematemesis and melena (25%). UGIB from ruptured esophageal varices was the most common cause (65%) on UGI endoscopy followed by gastric erosion (5%) and prolapsed gastropathy (2%). We observed that 23% of children were normal after endoscopic examination.

CONCLUSION

Ruptured esophageal varices were the most common cause of UGIB in children in Bangladesh. Other causes included gastric erosions and prolapsed gastropathy syndrome.

Age-specific causes of upper gastrointestinal bleeding in children

The etiology of upper gastrointestinal bleeding (UGIB) varies by age, from newborns to adolescents, with some of the causes overlapping between age groups. While particular causes such as vitamin K deficiency and cow's milk protein allergy are limited to specific age groups, occurring only in neonates and infants, others such as erosive esophagitis and gastritis may be identified at all ages. Furthermore, the incidence of UGIB is variable throughout the world and in different hospital settings. In North America and Europe, most UGIBs are non-variceal, associated with erosive esophagitis, gastritis, and gastric and duodenal ulcers. In recent years, the most common causes in some Middle Eastern and Far Eastern countries are becoming similar to those in Western countries. However, variceal bleeding still predominates in certain parts of the world, especially in South Asia. The most severe hemorrhage arises from variceal bleeding, peptic ulceration, and disseminated intravascular coagulation. Hematemesis is a credible indicator of a UGI source of bleeding in the majority of patients. Being familiar with the most likely UGIB causes in specific ages and geographic areas is especially important for adequate orientation in clinical settings, the use of proper diagnostic tests, and rapid initiation of the therapy. The fundamental approach to the management of UGIB includes an immediate assessment of severity, detecting possible causes, and providing hemodynamic stability, followed by early endoscopy. Unusual UGIB causes must always be considered when establishing a diagnosis in the pediatric population because some of them are unique to children. Endoscopic techniques are of significant diagnostic value, and combined with medicaments, may be used for the management of acute bleeding. Finally, surgical treatment is reserved for the most severe bleeding.

Gastrointestinal Bleeding in Children: The Role of Endoscopy and the Sheffield Scoring System in a Resource-Limited Setting

Objective

To document the clinical presentation, endoscopic diagnosis, and Sheffield scores of children with gastrointestinal (GI) bleeding who were referred for endoscopy at the Lagos University Teaching Hospital. The participants who needed endoscopy based on clinical criteria and according to the Sheffield scores were also documented.

Methods

This study analyzed the records of 111 children with GI bleeding retrospectively from January 2013 to January 2021, while 9 children were recruited prospectively from February 2021 to March 2022. Receiver operating curves and area under the curve were generated to test the ability of the Sheffield scores to predict rebleeds, mortality, and the need for endoscopic intervention for upper GI bleeds.

Results

One hundred and twenty participants were recruited. Ninety-one (75.8%) presented with upper GI bleeding (UGIB), while 29 (24.2%) had lower GI bleeding (LGIB). Only 70 (58.3%) (53 UGIB and 17 LGIB) had endoscopy performed. For UGIB, 5 (9.4%) had no source of the bleeding identified at endoscopy, 12 (22.6%) had variceal bleeding, and 36 (67.9%) had nonvariceal bleeding. Colonoscopy revealed juvenile polyps in 5 (29.4%), indeterminate colitis in 5 (29.4%), ulcerative colitis in 4 (23.5%), Crohn's disease in 1 (5.9%), and hemorrhoids in 2 (11.8%) participants, respectively. The Sheffield score was ≥8 in 42 (46.1%) of the participants who presented only with UGIB (hematemesis and melena). The scores were significantly related to the type of bleeds, rebleeds, and deaths (P = 0.00).

Conclusion

The clinical and endoscopic findings in this study are similar to those reported previously. The Sheffield scoring was useful in assessing Nigerian children. However, due to limited access and other restraints, endoscopy was not performed on all the study participants even when the scoring system was suggestive. The availability, and therefore, utility of GI endoscopy in this setting are still suboptimal. The need for the provision of adequate equipment and resources and the training of personnel is thus recommended.

Sulindac selectively induces autophagic apoptosis of GABAergic neurons and alters motor behaviour in zebrafish

Nonsteroidal anti-inflammatory drugs compose one of the most widely used classes of medications, but the risks for early development remain controversial, especially in the nervous system. Here, we utilized zebrafish larvae to assess the potentially toxic effects of nonsteroidal anti-inflammatory drugs and found that sulindac can selectively induce apoptosis of GABAergic neurons in the brains of zebrafish larvae brains. Zebrafish larvae exhibit hyperactive behaviour after sulindac exposure. We also found that akt1 is selectively expressed in GABAergic neurons and that SC97 (an Akt1 activator) and exogenous akt1 mRNA can reverse the apoptosis caused by sulindac. Further studies showed that sulindac binds to retinoid X receptor alpha (RXRα) and induces autophagy in GABAergic neurons, leading to activation of the mitochondrial apoptotic pathway. Finally, we verified that sulindac can lead to hyperactivity and selectively induce GABAergic neuron apoptosis in mice. These findings suggest that excessive use of sulindac may lead to early neurodevelopmental toxicity and increase the risk of hyperactivity, which could be associated with damage to GABAergic neurons.

Practical Aspects of Upper Gastrointestinal Bleeding in Children

Upper gastrointestinal bleeding (UGB) in children is a potentially life-threatening condition that represents a challenge for pediatricians and pediatric surgeons. It is defined as bleeding from any location within the upper esophagus to the ligament of Treitz. UGB can have many causes that vary with age. The impact on the child is often proportional to the amount of blood lost. This can range from mild bleeding that is unlikely to cause hemodynamic instability, to massive bleeding that requires admission to the intensive care unit. Proper and prompt management are very important factors in reducing morbidity and mortality. This article aims to summarize current research regarding the diagnosis and treatment of UGB. Most of the data used in the literature published on this subject is extrapolated from adulthood.

Gastrointestinal bleeding in children with familial dysautonomia: a case-control study

OBJECTIVE

Familial dysautonomia (FD) is a rare inherited autosomal recessive disorder with abnormal somatosensory, enteric, and afferent autonomic neurons. We aimed to define the incidence of gastrointestinal bleeding and its associated risk factors in patients with FD.

METHODS

In this retrospective case-control study, we identified all episodes of gastrointestinal bleeding in patients with FD, occurring over four decades (January 1980-December 2017), using the New York University FD registry.

RESULTS

We identified 104 episodes of gastrointestinal bleeding occurring in 60 patients with FD. The estimated incidence rate of gastrointestinal bleeds in the FD population rate was 4.20 episodes per 1000 person-years. We compared the 60 cases with 94 age-matched controls. Bleeding in the upper gastrointestinal tract from gastric and duodenal ulcers occurred most frequently (64 bleeds, 75.6%). Patients were more likely to have a gastrostomy (G)-tube and a Nissen fundoplication [odds ratio (OR) 3.73, 95% confidence interval (CI) 1.303-13.565] than controls. The mean time from G-tube placement to first gastrointestinal bleed was 7.01 years. The mean time from Nissen fundoplication to bleed was 7.01 years. Cases and controls had similar frequency of intake of nonsteroidal antiinflammatory drugs (NSAID) and selective serotonin reuptake inhibitors (SSRI).

CONCLUSION

The incidence of gastrointestinal bleeding in the pediatric FD population was estimated to be 4.20 per 1000 person-years, 21 times higher than in the general pediatric population (0.2 per 1000 person-years). Patients with FD with a G-tube and a Nissen fundoplication had a higher risk of a subsequent gastrointestinal bleeding.

Hematemesis in Infants: The First Evidence-Based Score to Predict the Need for Timely Endoscopy

OBJECTIVES

Infantile acute upper gastrointestinal bleeding involves a decision for therapeutic intervention that most pediatricians first coming into contact with the patient are, not unreasonably, unable to objectively provide. Therefore, some objective tools of individual risk assessment would seem to be crucial. The principal aim of the present study was to investigate the anamnestic and clinical parameters of infants with hematemesis, together with laboratory and instrumental findings, to create a scoring system that may help identify those infants requiring an appropriate and timely application of upper gastrointestinal (GI) endoscopy.

METHODS

Clinical data of infants admitted for hematemesis to the participating centers over the study period were systematically collected. According to the outcome dealing with rebleeding, need for blood transfusion, mortality, finding of GI bleeding lesions, or need for surgical intervention, patients were blindly divided into a group with major clinical severity and a group with minor clinical severity. Univariate and multivariate logistic regressions were conducted to investigate significant prognostic factors for clinical severity.

RESULTS

According to our findings, we drafted a practical diagnostic algorithm and a clinical score able to predict the need for timely upper GI endoscopy (BLOVO infant score). Our clinical scoring system was created by incorporating anamnestic factors, clinical parameters, and laboratory findings that emerged as predictors of a worst outcome.

CONCLUSIONS

We provided the first objective tool of individual risk assessment for infants with hematemesis, which could be very useful for pediatricians first coming into contact with the patient in the emergency department.

Long-term kidney and liver outcome in 50 children with autosomal recessive polycystic kidney disease

BACKGROUND

Autosomal recessive polycystic kidney disease (ARPKD) is a rare ciliopathy characterized by congenital hepatic fibrosis and cystic kidney disease. Lack of data about long-term follow-up makes it difficult to discuss timing and type of organ transplantation. Our objectives were to evaluate long-term evolution and indications for transplantation, from birth to adulthood.

METHODS

Neonatal survivors and patients diagnosed in postnatal period with ARPKD between 1985 January and 2017 December from 3 French pediatric centers were retrospectively enrolled in the study.

RESULTS

Fifty patients with mean follow-up 12.5 ± 1 years were enrolled. ARPKD was diagnosed before birth in 24%, and at mean age 1.8 years in others. Thirty-three patients were < 1 year of age at first symptoms, which were mostly kidney-related. These most often presented high blood pressure during follow-up. Portal hypertension was diagnosed in 29 patients (58%), 4 of them with bleeding from esophageal varices. Eight patients presented cholangitis (> 3 episodes in three children). Liver function was normal in all patients. Nine children received a kidney transplant without liver complications. A 20-year-old patient received a combined liver-kidney transplant (CLKT) for recurrent cholangitis, and a 15-year-old boy an isolated liver transplant for uncontrollable variceal bleeding despite portosystemic shunt.

CONCLUSIONS

Long-term outcome in patients with ARPKD is heterogeneous, and in this cohort did not depend on age at diagnosis except for blood pressure. Few patients required liver transplantation. Indications for liver or combined liver-kidney transplantation were limited to recurrent cholangitis or uncontrollable portal hypertension. Liver complications after kidney transplantation were not significant.

Prescribing patterns, indications and adverse events of ibuprofen in children: results from a national survey among Italian pediatricians

Background

Despite ibuprofen widely recognized safety profile, an increase of suspected adverse events has been reported in the last decade in parallel with its growing over-the-counter use. The aims of this study were to assess the therapeutic approach to the feverish child and to evaluate the main indications and the most frequent adverse events related to ibuprofen administration in children.

Methods

A specific questionnaire-form regarding the management of ibuprofen therapy in children was distributed among a sample of pediatricians all over the Italian territory between September and October 2020. An electronic data collection through a specifically designed web-based platform was performed among the participating pediatricians.

Results

One-hundred-eighty-one pediatricians completed the survey. In case of fever, 177 (98%) participants prescribe paracetamol, while only 4 (2%) preferred ibuprofen as first choice. One-hundred-twenty-eight pediatricians (71%) administer paracetamol alone, while 53 (29.2%) use the combined/alternating treatment with ibuprofen. Ibuprofen is mostly administered for musculoskeletal pain (30%), upper respiratory tract infection (20%), headache (15%) and post-surgical pain (9%). Sixty-three (35%) out of 181 participating pediatricians reported 191 adverse events during ibuprofen administration. The most common were gastrointestinal (GI), with GI bleeding being reported in 30/191 cases (15.7%), epigastric pain in 29/191 (15.1%), non-specified abdominal pain in 22/191 (11.1%) and nausea/vomiting in 21/191 (11%). Severe adverse events including kidney damage (3.1%), complicated infections (0.5%), pneumonia associated empyema (0.5%), soft tissue infection (0.5%) and disseminated intravascular coagulation (0.5%) were also reported. The adverse events led to a hospitalization in 12% of children. In 53/191 cases (28%) the adverse events were related to a wrong dosage or prolonged therapy or errors in frequency of administration.

Conclusions

This survey demonstrate a sufficient awareness of Italian pediatricians regarding ibuprofen-prescribing patterns with the only possible concern related to the relatively high percentage of pediatricians performing a combining/alternating use of paracetamol and ibuprofen. The reported adverse events were mild in most of the cases and often related to errors in dosage, frequency and treatment duration, emphasizing the need for a major caution of both practitioners and patients in their use.

Serious infectious events and ibuprofen administration in pediatrics: a narrative review in the era of COVID-19 pandemic

Purpose of review

Despite its recognized efficacy and tolerability profile, during the last decade a rise of adverse events following ibuprofen administration in children has been reported, including a possible role in worsening the clinical course of infections. Our aim was to critically evaluate the safety of ibuprofen during the course of pediatric infectious disease in order to promote its appropriate use in children.

Recent findings

Ibuprofen is associated with severe necrotizing soft tissue infections (NSTI) during chickenpox course. Pre-hospital use of ibuprofen seems to increase the risk of complicated pneumonia in children. Conflicting data have been published in septic children, while ibuprofen in the setting of Cystic Fibrosis (CF) exacerbations is safe and efficacious. No data is yet available for ibuprofen use during COVID-19 course.

Summary

Ibuprofen should not be recommended for chickenpox management. Due to possible higher risks of complicated pneumonia, we suggest caution on its use in children with respiratory symptoms. While it remains unclear whether ibuprofen may have harmful effects during systemic bacterial infection, its administration is recommended in CF course. Despite the lack of data, it is seems cautious to prefer the use of paracetamol during COVID-19 acute respiratory distress syndrome in children.

Comparison of anticoagulation and antiplatelet therapy for treatment of blunt cerebrovascular injury in children <10 years of age: a multicenter retrospective cohort study

PURPOSE

Blunt cerebrovascular injury (BCVI) is uncommon in the pediatric population. Among the management options is medical management consisting of antithrombotic therapy with either antiplatelets or anticoagulation. There is no consensus on whether administration of antiplatelets or anticoagulation is more appropriate for BCVI in children < 10 years of age. Our goal was to compare radiographic and clinical outcomes based on medical treatment modality for BCVI in children < 10 years.

METHODS

Clinical and radiographic data were collected retrospectively for children screened for BCVI with computed tomography angiography at 5 academic pediatric trauma centers.

RESULTS

Among 651 patients evaluated with computed tomography angiography to screen for BCVI, 17 patients aged less than 10 years were diagnosed with BCVI (7 grade I, 5 grade II, 1 grade III, 4 grade IV) and received anticoagulation or antiplatelet therapy for 18 total injuries: 11 intracranial carotid artery, 4 extracranial carotid artery, and 3 extracranial vertebral artery injuries. Eleven patients were treated with antiplatelets (10 aspirin, 1 clopidogrel) and 6 with anticoagulation (4 unfractionated heparin, 2 low-molecular-weight heparin, 1 transitioned from the former to the latter). There were no complications secondary to treatment. One patient who received anticoagulation died as a result of the traumatic injuries. In aggregate, children treated with antiplatelet therapy demonstrated healing on 52% of follow-up imaging studies versus 25% in the anticoagulation cohort.

CONCLUSION

There were no observed differences in the rate of hemorrhagic complications between anticoagulation and antiplatelet therapy for BCVI in children < 10 years, with a nonsignificantly better rate of healing on follow-up imaging in children who underwent antiplatelet therapy; however, the study cohort was small despite including patients from 5 hospitals.

Current status and future challenges in the endoscopic management of non-variceal upper gastrointestinal bleeding in children

PURPOSE

This study aimed to elucidate the characteristics of non-variceal upper gastrointestinal bleeding (NVUGIB) in children and the outcomes of endoscopic hemostasis (EH) performed by pediatric surgeons.

METHODS

We retrospectively reviewed the medical records of pediatric patients with NVUGIB who had undergone esophagogastroduodenoscopy (EGD) at our hospital, between December 2006 and March 2020.

RESULTS

Thirty-six patients were included. The most common endoscopic diagnosis was gastritis (28%), followed by gastric ulcer (25%) and duodenal ulcer (25%). Thirty patients (83%) had underlying diseases, including a recent viral infection (39%), followed by Helicobacter pylori infection (14%). Fourteen patients (39%) underwent EH, exhibiting a high initial rate of hemostasis (100%). This was achieved in 12/14 patients by clipping. One patient was treated using a combination of a hypersaline and epinephrine (HSE) injection and coagulation therapy, as the ulcer exceeded the width of the hemoclips. Rebleeding occurred in one patient (7.1%) initially treated with pure ethanol injections. The partial view of the pediatric duodenum prevented the placement of hemoclips; hence, the patient was treated using a combination of HSE and coagulation therapy.

CONCLUSION

Clipping, injection, and/or coagulation therapy can lead to high success rates for hemostasis, considering the anatomical characteristics in a pediatric population.

Adverse effects of non-steroidal anti-inflammatory drugs in patients with viral respiratory infections: rapid systematic review

OBJECTIVES

To assess the effects of non-steroidal anti-inflammatory drugs (NSAIDs) in patients with viral respiratory infections on acute severe adverse outcomes, healthcare utilisation, quality of life and long-term survival.

DESIGN

Rapid systematic review.

PARTICIPANTS

Humans with viral respiratory infections, exposed to systemic NSAIDs.

PRIMARY OUTCOMES

Acute severe adverse outcomes, healthcare utilisation, quality of life and long-term survival.

RESULTS

We screened 10 999 titles and abstracts and 738 full texts, including 87 studies. No studies addressed COVID-19, Severe Acute Respiratory Syndrome or Middle East Respiratory Syndrome; none examined inpatient healthcare utilisation, quality of life or long-term survival. Effects of NSAIDs on mortality and cardiovascular events in adults with viral respiratory infections are unclear (three observational studies; very low certainty). Children with empyema and gastrointestinal bleeding may be more likely to have taken NSAIDs than children without these conditions (two observational studies; very low certainty). In patients aged 3 years and older with acute respiratory infections, ibuprofen is associated with a higher rate of reconsultations with general practitioners than paracetamol (one randomised controlled trial (RCT); low certainty). The difference in death from all causes and hospitalisation for renal failure and anaphylaxis between children with fever receiving ibuprofen versus paracetamol is likely to be less than 1 per 10 000 (1 RCT; moderate/high certainty). Twenty-eight studies in adults and 42 studies in children report adverse event counts. Most report that no severe adverse events occurred. Due to methodological limitations of adverse event counts, this evidence should be interpreted with caution.

CONCLUSIONS

It is unclear whether the use of NSAIDs increases the risk of severe adverse outcomes in patients with viral respiratory infections. This absence of evidence should not be interpreted as evidence for the absence of such risk. This is a rapid review with a number of limitations.

[Benefits and risks of ibuprofen in children with fever: Overview of the literature with a view to producing a written information tool for parents]

Drug information, as it appears in package leaflet, lacks relevant encrypted data for the patient. The aim of our research was to propose a written model of drug information inspired from the concept of the "Drug Facts Box", about ibuprofen in children with fever. To this end, we carried out a systematic review of systematic literature reviews ("overview") to look for data on the benefits and risks of ibuprofen compared to placebo, paracetamol or a treatment alternating or combining paracetamol and ibuprofen in children with fever aged 0-18 years. 9 systematic reviews were included from the Pubmed/Medline, Embase and Cochrane databases. 1 clinical practice guideline and 2 documents published by the French Haute Autorité de santé (HAS) and the French Agence nationale de sécurité du médicament et des produits de santé (ANSM) were also included. Paracetamol and ibuprofen have a comparable efficacy and safety profile in children with fever. A low increased risk of adverse reactions to ibuprofen is to be feared in specifics clinical situations (chicken pox, pneumonia, angina). Treatments alternating or combining paracetamol and ibuprofen can further lower the temperature compared to paracetamol or ibuprofen alone, but there is no evidence of improved child comfort. The limited data available on the adverse effects of these treatment regimens suggests that they should not be routinely recommended. There is little evidence of the comfort of the febrile child even though it is the primary objective of antipyretic treatment.

Parental Experience of Potential Adverse Drug Reactions Related to Their Oral Administration of Antipyretic Analgesic Medicines in Children in Saudi Arabia

BACKGROUND

Oral antipyretic analgesic medicines are commonly used in children and have the potential for adverse drug reactions (ADRs).

OBJECTIVE

The aim of this study was to explore parental experiences of potential ADRs related to their oral administration of antipyretic analgesics in children in the Kingdom of Saudi Arabia.

METHODS

For this cross-sectional survey, a paper-based questionnaire, consent form and information sheet were handed out to 1000 parents who had administered an oral antipyretic analgesic medicine to their children during the previous 3 months. Data were entered and analyzed using SPSS version 21.0 (IBM-SPSS Inc, Armonk, NY). Simple descriptive and inferential statistics were used. Management and ethical approvals were attained.

RESULTS

During March to April 2017, 661 parents agreed to participate, giving a response rate of 66.1%. Of the surveyed sample, 208 parents had observed 1 or more potential ADRs (31.5%, n = 208 out of 661). Parents' (n = 208) most commonly reported potential ADRs (n = 523) were loss of appetite (23%, n = 120 out of 523), stomachache (20.3%, n = 106 out of 523), abdominal colic (13%, n = 68 out of 523), and diarrhea (10.3%, n = 54 out of 523). Parents described severity of the ADRs as slight (71.8%, n = 342 out of 476), annoying to the child (7.9%, n = 85 to of 476), significant and affecting daily tasks (3.6%, n = 17 out of 476) and significant and led to the hospital (6.7%, n = 32 out of 476). Fever was the top-ranked reason for using antipyretic analgesic medicines (41.0%, n = 271 out of 661), followed by toothache (25.0%, n = 165 out of 661) and tonsillitis/laryngitis (24.7%, n = 163 out of 661). Among parents, 34.7% (n = 165 out of 476) did not seek medical attention when a potential ADR occurred, whereas 26.3% (n = 125 out of 476) of parents took their children to hospital clinics.

CONCLUSIONS

Although the majority of parentally reported (but not proven) ADRs were mild, a number of significant ADRs were reported. Future research should consider whether there is a role for physicians and pharmacists in educating parents in Saudi Arabia, and perhaps more widely, about the optimal use of oral antipyretic and analgesic medicines in children.

Acute pain management in children: a survey of Italian pediatricians

BACKGROUND

Current guidelines recommend assessing and relieving pain in all children and in all instances; yet, in clinical practice, management is frequently suboptimal. We investigated the attitude of Italian family pediatricians towards the evaluation and treatment of different types of acute pain in children aged 7-12 years.

METHODS

This is a cross-sectional study based on a 17-question survey accessible online from October 2017 to October 2018. Responders had to describe cases of children suffering from any type of acute pain among headache, sore throat, musculoskeletal/post-traumatic pain, and earache. Children's characteristics, pain assessment modalities and therapeutic approaches were queried. The following tests were used: Z-proportion to evaluate the distribution of categorical data; chi-squared and Kruskall-Wallis to explore data heterogeneity across groups; Mann-Whitney for head-to-head comparisons.

RESULTS

Overall, 929 pediatricians presented 6335 cases uniformly distributed across the types examined. Pain was more frequently of moderate intensity (42.2%, P < 0.001) and short duration (within some days: 98.4%, P < 0.001). Only 50.1% of responders used an algometric scale to measure pain and 60.5% always prescribed a treatment. In children with mild-moderate pain (N = 4438), the most commonly used first-line non-opioids were ibuprofen (53.3%) and acetaminophen (44.4%). Importantly, a non-recommended dosage was prescribed in only 5.3% of acetaminophen-treated cases (overdosing). Among the misconceptions emerged, there were the following: i) ibuprofen and acetaminophen have different efficacy and safety profiles (when choosing the non-opioid, effectiveness weighted more for ibuprofen [79.7% vs 74.3%, P < 0.001] and tolerability for acetaminophen [74.0% vs 55.4%, P < 0.001]); ii) ibuprofen must be taken after meals to prevent gastric toxicities (52.5%); ibuprofen and acetaminophen can be used combined/alternated for persisting mild-moderate pain (16.1%). In case of moderate-severe pain not completely controlled by opioids, ibuprofen and acetaminophen were the most used add-on medications, with ibuprofen being much more prescribed than acetaminophen (65.2% vs 23.7%, respectively) overall and in all pain types.

CONCLUSIONS

Several gaps exist between the current practice of pain assessment and treatment and recommendations. Further efforts are needed to raise awareness and improve education on the possible exposure of the child to short- and long-term consequences in case of suboptimal pain management.

Analysis of risk factors and development of scoring system to predict severity of upper gastrointestinal bleeding in children

BACKGROUND AND AIM

Upper gastrointestinal bleeding is a rare and potentially life-threatening condition in children. Herein, clinical features and risk factors in children with upper gastrointestinal bleeding were analyzed, and a clinical scoring system was constructed to assess severity.

METHODS

This retrospective cohort study involved 224 children hospitalized with upper gastrointestinal bleeding between January 2012 and April 2018. Demographic data, clinical information, and laboratory test results on admission were statistically examined.

RESULTS

Out of 224 upper gastrointestinal bleeding cases, 76 were diagnosed as severe and 148 as mild cases according to the rate of blood loss and severity. Severe group was significantly different from mild group in 23 items including age, number of patients aged more than 7 years, and so forth (P < 0.01 or P < 0.05). Positive detection rate of bleeding etiology was gradually decreased (P < 0.01) in relation to delay in timing of endoscopy. Analysis of logistic regression evinced five independent risk factors for severe cases to be associated with poor consciousness, hemoglobin < 80 g/L, hemoglobin drop of > 20 g/L, hematochezia, and anemic appearance (P < 0.01 or P < 0.05). Using these five parameters, a number of scoring models were tested. The most predictive resulted in a scoring system constructed with a total of 16 and a cutoff for intervention of 8.

CONCLUSIONS

Amalgamation of risk factors with the scoring system plays an important role in assessing upper gastrointestinal bleeding severity in children.

Aspirin in childhood acute ischemic stroke: The evidence for treatment and efficacy testing

Aspirin is the most commonly prescribed antiplatelet agent worldwide, but evidence supporting its use varies by age and disease process. Despite its frequent use in childhood acute ischemic stroke prevention and management, major knowledge gaps exist about optimal pediatric aspirin use, particularly in this setting, where high-quality clinical trials are urgently needed. This review focuses upon the evidence for aspirin use in childhood acute ischemic stroke, includes a summary of aspirin pharmacology to highlight misconceptions and common clinical situations which may limit its efficacy, and discusses the techniques and potential role of laboratory monitoring of aspirin efficacy in children.

Ibuprofen in the treatment of children's inflammatory pain: a clinical and pharmacological overview

Unlike fever, which is often over-treated especially in children, pain is underestimated and under-treated in pediatric age. The pharmacological agents approved for treating pain in these patients are few, also considering the recent limitation for codeine in children younger than 12 years. Paracetamol and the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen are the most used at this purpose. The aim of this overview was to analyze the therapeutic appropriateness of ibuprofen in children based on its pharmacological properties. This work is a critical review of the pediatric literature over the last 20 years on efficacy and adverse events associated with the use of ibuprofen as analgesic in the pediatric population. Ibuprofen resulted effective in several pain conditions in children such as musculoskeletal pain, ear pain and acute otitis media, toothache and the inflammatory disease of the oral cavity and pharynx. The drug is a reasonable and efficacious alternative in postoperative pain, including tonsillectomy and adenoidectomy. It remains the treatment of choice for pain in chronic inflammatory diseases such as arthritis. Side effects and adverse events associated with ibuprofen are mild. It has the lowest gastrointestinal (GI) toxicity among NSAIDs, although some cases of GI toxicity may occur. Its renal effects are minimal, but dehydration plays an important role in triggering renal damage, so ibuprofen should not be given to patients with vomiting and diarrhea. Ibuprofen showed a good safety profile and provided evidence of effectiveness for mild-moderate pain of different origin in children. In case of fever or pain, the choice about the drug to be used should fall on ibuprofen in a clinical context where there is an inflammatory pathogenesis.

Diagnostic and therapeutic approach to upper gastrointestinal bleeding

BACKGROUND

There is a lack of clarity about the approach to and management of upper gastrointestinal (UGI) bleeding in children.

AIM

To examine the recent literature on UGI bleeding in children in order to outline the diagnostic approach and management.

METHODS

The English language literature was searched for articles on UGI bleeding in children. Special attention was paid to its prevalence, risk factors, clinical approach and management.

RESULTS

Although UGI bleeding is a common complication (10%) in paediatric intensive care units (PICU), clinically significant UGI bleeding (haemodynamic instability, fall in haemoglobin by 2 g/dL and/or a requirement for blood transfusion) is less common (1.6%). In low- and middle-income countries, clinically significant UGI bleeding is commonly owing to variceal bleeding whereas non-variceal aetiologies (e.g. peptic ulcer disease) are common in high-income countries. The fundamental clinical principles of managing UGI bleeding are immediate assessment of severity, detecting possible causes and stabilising the haemodynamic status. In suspected cases of variceal bleeding, intravenous octreotide and, in non-variceal bleeding, administration of a proton pump inhibitor (PPI) should be commenced immediately. UGI endoscopy plays a vital role in diagnosis and management. Over-transfusion should be avoided (target haemoglobin 7-9 g/dL). Stress ulcer prophylaxis is recommended in a select group of patients in PICUs (e.g. respiratory failure, coagulopathy and paediatric risk of mortality score ≥10).

CONCLUSIONS

In clinically significant UGI bleeding, the primary goal is to restore the haemodynamic status, followed by early endoscopy. Intravenous octreotide in suspected variceal and PPI in non-variceal bleeding should be administered early. Stress ulcer prophylaxis should be restricted to high-risk children only.

Working Towards an Appropriate Use of Ibuprofen in Children: An Evidence-Based Appraisal

Ibuprofen is the most widely used non-steroidal anti-inflammatory drug (NSAID) for the treatment of inflammation, mild-to-moderate pain and fever in children, and is the only NSAID approved for use in children aged ≥3 months. Its efficacy and safety profile have led to its increasing use in paediatric care, even without medical prescription. However, an increase of suspected adverse reactions to ibuprofen has been noted in concomitance with the raised, often medically unsupervised, consumption of the drug. The purpose of this work was a critical review of the paediatric literature over the last 15 years on side effects and adverse events associated with ibuprofen, in order to highlight circumstances associated with higher risks and to promote safe and appropriate use of this drug. The literature from 2000 to date demonstrates that gastrointestinal events are rare, but (when they occur) include both upper and lower digestive tract lesions. Dehydration plays an important role in triggering renal damage, so ibuprofen should not be given to patients with diarrhoea and vomiting, with or without fever. Likewise, ibuprofen should never be administered to patients who are sensitive to it or to other NSAIDs. It is contraindicated in neonates and in children with wheezing and persistent asthma and/or during varicella. Most of the analysed studies reported adverse events when ibuprofen was being used for fever symptoms or flu-like syndrome. Ibuprofen should not be used as an antipyretic, except in rare cases. Ibuprofen remains the drug of first choice in the treatment of inflammatory pain in children.

Risk factors associated with clinically significant gastrointestinal bleeding in pediatric ED

INTRODUCTION

Gastrointestinal bleeding is a common problem in pediatric emergency department (PED). Some of these patients can lose significant amount of blood which may lead to shock. The aim of this study is to determine the risk factors predicting clinically significant gastrointestinal (GIS) bleeding in patients presenting to PED.

METHODS

This study was performed prospectively from January 1st 2013 to December 31th 2013 in patients with upper or lower GIS bleeding. Clinically significant GIS bleeding was defined as >2g/dL hemoglobin decrease at any time during observation in PED, need for erythrocyte transfusion or need for rapid endoscopic evaluation.

RESULTS

105 patients were enrolled, 81 of which were eligible for the study. Twenty two patients (26,8%) had clinically significant GIS bleeding. These patients have significantly more commonly have upper GI bleeding and symptoms of melena, pallor and tachycardia. Initial laboratory findings revealed lower hemoglobin, RBC and albumin levels with higher WBC and BUN levels. They need significantly more nasogastric tube placement and PPI and H2 blocker treatment. Final diagnosis included more gastritis and peptic ulcers. These patients have less hematochezia, less lower gastrointestinal bleeding and less commonly diagnosed as acute gastroenteritis or Mallory Weiss tear as a final diagnosis.

CONCLUSIONS

Pediatric emergency physicians should be aware of clinical and laboratory parameters of patients with clinically significant GIS bleeding to predict which patients are under risk of life threatening blood loss. Patients who have melena, pallor, tachycardia, anemia and uremia at presentation are more prone to have significant GIS bleeding.

Upper Gastrointestinal Bleeding in Children: A Tertiary United Kingdom Children's Hospital Experience

The aim of this study was to review the aetiology, presentation and management of these patients with upper gastrointestinal bleeding (UGIB) at a tertiary children’s unit in the United Kingdom. This was a retrospective single-institution study on children (<16 years) who presented with acute UGIB over a period of 5 years using known International Classification of Diseases (ICD) codes. A total of 32 children (17 males, 15 females) were identified with a total median age at presentation of 5.5 years. The majority (24/32) of patients presented as an emergency. A total of 19/32 presented with isolated haematemesis, 8/32 with isolated melaena and 5/32 with a combination of melaena and haematemesis. On admission, the mean haemoglobin of patients who presented with isolated haematemesis was 11 g/dL, those with isolated melaena 9.3 g/dL and those with a combination 7.8 g/dL. Blood transfusion was required in 3/19 with haematemesis and 3/5 with haematemesis and melaena. A total of 19/32 underwent upper gastrointestinal endoscopy. Endoscopic findings were oesophageal varices (5/19) of which 4 required banding; bleeding gastric ulcer (1/19) requiring clips, haemospray and adrenaline; gastric vascular malformation (1/19) treated with Argon plasma coagulation therapy; duodenal ulcer (3/19) which required surgery in two cases; oesophagitis (5/19); and gastritis +/− duodenitis (3/19). A total of 13/32 patients did not undergo endoscopy and the presumed aetiology was a Mallory–Weiss tear (4/13); ingestion of foreign body (2/13); gastritis (3/13); viral illness (1/13); unknown (2/13). While UGIB is uncommon in children, the morbidity associated with it is very significant. Melaena, dropping haemoglobin, and requirement for a blood transfusion appear to be significant markers of an underlying cause of UGIB that requires therapeutic intervention. A multi-disciplinary team comprising gastroenterologists and surgeons is essential.

Etiology and outcome in patients with upper gastrointestinal bleeding: Study on 4747 patients in the central region of Iran

BACKGROUND AND AIM

Upper gastrointestinal bleeding (UGIB) is a threatening condition leading to urgent hospitalization. This study aims to investigate etiology and outcome in UGIB patients in Iran.

METHODS

Medical records of GIB patients admitted to Alzahra referral hospital (in Isfahan) during 2010-2015 were retrospectively reviewed for demographic data, comorbidities, history of smoking and taking non-steroidal anti-inflammatory drugs (NSAIDs), presenting symptoms, endoscopic findings, therapeutic endoscopy, blood products' infusion, surgical intervention, rebleeding, and mortality.

RESULTS

A total of 4747 patients were enrolled in the study (69.2% men, mean age = 55.46 ± 21.98 years). Hematemesis was the most frequent presenting symptom (63.5%). Peptic ulcer (duodenal ulcer in most cases) was seen as the main reason for UGIB (42.4%). Rebleeding (present in 16.5% of patients) was found to be more frequent in patients with older age, presenting sign of hematochezia and hypotension, history of taking NSAIDs and smoking, presence of comorbidities, history of bleeding because of UGI tract neoplasm and esophageal varices, history of needing blood products' infusion, and history of therapeutic endoscopy or surgical intervention (P < 0.005). We found that mortality (5.5% in total) was also higher in the same group of patients that were seen to have a higher tendency for rebleeding (P < 0.005).

CONCLUSION

Peptic ulcers are the most common cause of UGIB. Comorbidities, hemodynamic instability, high-risk endoscopic stigmata, history of smoking and taking NSAIDs, gastric and esophageal malignancies, may be important predisposing factors for rebleeding and mortality in patients with UGIB.

A clinical and safety review of paracetamol and ibuprofen in children

The antipyretic analgesics, paracetamol, and non-steroidal anti-inflammatory agents NSAIDs are one of the most widely used classes of medications in children. The aim of this review is to determine if there are any clinically relevant differences in safety between ibuprofen and paracetamol that may recommend one agent over the other in the management of fever and discomfort in children older than 3 months of age.

Indications for gastrointestinal endoscopy in childhood

Endoscopic examination of the gastrointestinal tract (GIT) for diagnostics and therapy in children has evolved markedly over the last 20 or so years and is now usually undertaken by paediatric endoscopists. Updated diagnostic and management guidelines for common disorders including coeliac disease, gastro-oesophageal reflux disease, eosinophilic oesophagitis and inflammatory bowel disease highlight the central role of endoscopy. Therapeutic endoscopic approaches are also now widely available and further broaden the referral spectrum to include treatment of GIT bleeding, gastrostomy insertion, dilation of strictures and polypectomy. Lastly, the advent of newer technologies allows the examination of hitherto inaccessible areas of the GIT such as the mid-small bowel by wireless capsule video-endoscopy and enteroscopy. We summarise recent current practice and clinical guidelines, focussing on the key indications for referrals that are likely to require endoscopic assessment.

National cross-sectional study of nonsteroidal anti-inflammatory drugs use highlights differences between parents and professionals and prompts safety concerns

AIM

Controversy surrounding the safety of nonsteroidal anti-inflammatory drugs (NSAIDs) provides an opportunity to study parents' and healthcare professionals' differential use of over-the-counter drugs.

METHODS

In this national cross-sectional study, general practitioners, paediatricians and pharmacists were asked to include up to five consecutive febrile paediatric patients aged 1 month to 12 years. Parents and healthcare professionals completed questionnaires about the current fever episode. We studied the differential use of NSAIDs by parents and healthcare professionals notably in three clinical conditions with various estimated risk of NSAIDs complications: varicella, gastroenteritis and pharyngitis.

RESULTS

The 1534 healthcare professionals prescribed 15% of the 6596 children with an NSAID, but 32% of the parents gave their child an NSAID. Generally, NSAID use was associated with older children, higher temperatures, pain due to otitis and the absence of a rash or gastroenteritis. The differential use of NSAIDs by parents and professionals was greater in conditions with high than low estimated risks of NSAID complications, with odds ratios ranging from to 9.0 to 2.9, respectively.

CONCLUSION

The differential use of NSAIDs by healthcare professionals and parents for clinical conditions with potential risks should prompt discussions about the safety of their over-the-counter status.

Upper Gastrointestinal Bleeding in Chinese Children: A Multicenter 10-Year Retrospective Study

Objective This study aims to analyze the clinical and endoscopic presentations of upper gastrointestinal bleeding (UGIB) in the Chinese children. Methods A 10-year retrospective study was made on children with UGIB and undertaken esophagogastroduodenoscopy (EGD) from 4 tertiary referral centers in China. Results Of the 1218 children studied, the bleeding source was found in 76.4%. Erosive gastritis was the most common endoscopic finding (33.5%), followed by duodenal ulcer (23.2%). The proportion of erosive gastritis decreased with age (correlation coefficient = -0.787), and duodenal ulcer increased with age (correlation coefficient = 0.958). The bleeding source was more likely to be determined in children having EGDs within 48 hours (80.6% vs 67.9%). Conclusions In Chinese children with UGIB, erosive gastritis and duodenal ulcer were the leading causes, and their proportions varied with age. EGDs performed within 48 hours may improve the possibility of finding the source of bleeding.

Nonsteroidal Anti-Inflammatory Drug Toxicity in Children: A Clinical Review

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most widely used classes of medications in children. Despite a reported positive safety profile, NSAIDs have been associated with toxicities in both overdose and routine use. Most children with NSAID overdoses are asymptomatic and should be managed conservatively, whereas a small number may present with severe symptoms. We review NSAID exposures in children and strategies for their clinical evaluation and management.

Italian survey on non-steroidal anti-inflammatory drugs and gastrointestinal bleeding in children

AIM: To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug (NSAIDs) use in children.

METHODS: A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber (physician or self-medication) were examined.

RESULTS: Fifty-one patients, including 34 males, were enrolled (median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients (68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients (56.9%)]. Seven patients had positive family history of Helicobacter pylori (H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four (47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom (33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51 (62%) patients, duodenal lesions in 17 (33%) and esophageal lesions in 8 (15%). In 10/51 (19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight (94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51 (6%) patients, an endoscopic hemostasis was needed.

CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in children

Symptomatic Management of Fever in Children: A National Survey of Healthcare Professionals' Practices in France

Despite the production and dissemination of recommendations related to managing fever in children, this symptom saturates the practices of primary healthcare professionals (HPs). Data on parent practices related to fever are available, but data on HPs’ practices are limited. We studied HPs’ practices, determinants of practices and concordance with recommendations in France. We conducted a national cross-sectional observational study between 2007 and 2008 among French general practitioners, primary care pediatricians and pharmacists. HPs were asked to include 5 consecutive patients aged 1 month to 12 years with acute fever. HPs completed a questionnaire about their practices for the current fever episode. We used a multilevel logistic regression model to assess the joint effects of patient- and HP-level variables associated with this behavior. In all, 1,534 HPs (participation rate 13%) included 6,596 children (mean age 3.7 ± 2.7 years). Physicians measured the temperature of 40% of children. Primary HPs recommended drug treatment for 84% of children (including monotherapy for 92%) and physical treatment for 62% (including all recommended physical treatments for 7%). HPs gave written advice or a pamphlet for 13% of children. Significant practice variations were associated with characteristics of the child (age, fever level and diagnosis) and HP (profession and experience). In France, despite the production and dissemination of national recommendations for managing fever in children, primary HPs’ observed practices differed greatly from current recommendations, which suggests potential targets for continuing medical education.

A practical approach to the treatment of low-risk childhood fever

Fever is a common symptom of childhood infections that in itself does not require treatment. The UK’s National Institute for Health and Care Excellence (NICE) advises home-based antipyretic treatment for low-risk feverish children only if the child appears distressed. The recommended antipyretics are ibuprofen or paracetamol (acetaminophen). They are equally recommended for the distressed, feverish child; therefore, healthcare professionals, parents and caregivers need to decide which of these agents to administer if the child is distressed. This narrative literature review examines recent data on ibuprofen and paracetamol in feverish children to determine any clinically relevant differences between these agents. The data suggest that these agents have similar safety profiles in this setting and in the absence of underlying health issues, ibuprofen seems to be more effective than paracetamol at reducing NICE’s treatment criterion, ‘distress’ (as assessed by discomfort levels, symptom relief, and general behavior).

Defining a reference set to support methodological research in drug safety

BACKGROUND

Methodological research to evaluate the performance of methods requires a benchmark to serve as a referent comparison. In drug safety, the performance of analyses of spontaneous adverse event reporting databases and observational healthcare data, such as administrative claims and electronic health records, has been limited by the lack of such standards.

OBJECTIVES

To establish a reference set of test cases that contain both positive and negative controls, which can serve the basis for methodological research in evaluating methods performance in identifying drug safety issues.

RESEARCH DESIGN

Systematic literature review and natural language processing of structured product labeling was performed to identify evidence to support the classification of drugs as either positive controls or negative controls for four outcomes: acute liver injury, acute kidney injury, acute myocardial infarction, and upper gastrointestinal bleeding.

RESULTS

Three-hundred and ninety-nine test cases comprised of 165 positive controls and 234 negative controls were identified across the four outcomes. The majority of positive controls for acute kidney injury and upper gastrointestinal bleeding were supported by randomized clinical trial evidence, while the majority of positive controls for acute liver injury and acute myocardial infarction were only supported based on published case reports. Literature estimates for the positive controls shows substantial variability that limits the ability to establish a reference set with known effect sizes.

CONCLUSIONS

A reference set of test cases can be established to facilitate methodological research in drug safety. Creating a sufficient sample of drug-outcome pairs with binary classification of having no effect (negative controls) or having an increased effect (positive controls) is possible and can enable estimation of predictive accuracy through discrimination. Since the magnitude of the positive effects cannot be reliably obtained and the quality of evidence may vary across outcomes, assumptions are required to use the test cases in real data for purposes of measuring bias, mean squared error, or coverage probability.

Diagnostic endoscopy and clinical characteristics of gastrointestinal bleeding in children: a 10-year retrospective study

Background

Upper gastrointestinal (UGI) endoscopy is a tool used frequently in the evaluation of patients presented with hematemesis.

Objectives

The purpose of this study was to evaluate clinical presentations and features of UGI bleeding (UGIB) in children.

Methods/Patients and Materials

A descriptive retrospective analysis was carried out on the medical records of the patients. Children and adolescents aging 0 – 18 years who were presented with UGIB were recruited in the survey over a period of 10 years (2000 to 2010) in Children's Hospital, Tabriz, Iran.

Results

There were 447 patients included in this study and they were all evaluated by upper endoscopy. Clinical manifestations included hematemesis (120 cases, 26.85%), melena (60 cases, 13.42%), and hematochezia (11 cases, 2.46%). Age-related analysis showed that erosive esophagities was a more common cause of hematemesis in the younger age group (under 1 year of age) with a prevalence of 37% when compared with elder children and adolescents (40%). Peptic ulcer disease was seen in only 7.4% of infants under the age of one. Overall, Esophagitis and erosive esophagitis was the most common endoscopic finding (179, 40%) .

Conclusions

There were 80 (17.90%) patients receiving endoscopic hemostatic therapy. In children with UGIB, upper endoscopy is a diagnostic procedure for the categorization of underlying causes of upper gastrointestinal bleeding in children and various endoscopic lesions may be found in a patient with the impression of UGIB.

Drug use and upper gastrointestinal complications in children: a case-control study

OBJECTIVE

To evaluate the risk of upper gastrointestinal complications (UGIC) associated with drug use in the paediatric population.

METHODS

This study is part of a large Italian prospective multicentre study. The study population included children hospitalised for acute conditions through the emergency departments of eight clinical centres. Patients admitted for UGIC (defined as endoscopically confirmed gastroduodenal lesions or clinically defined haematemesis or melena) comprised the case series; children hospitalised for neurological disorders formed the control group. Information on drug and vaccine exposure was collected through parental interview during the children's hospitalisation. Logistic regression was used to estimate ORs for the occurrence of UGIC associated with drug use adjusted for age, clinical centre and concomitant use of any drug.

RESULTS

486 children hospitalised for UGIC and 1930 for neurological disorders were enrolled between November 1999 and November 2010. Drug use was higher in cases than in controls (73% vs 54%; p<0.001). UGICs were associated with the use of non-steroidal anti-inflammatory drugs (NSAIDs) (adjusted OR 2.9, 95% CI 2.1 to 4.0), oral steroids (adjusted OR 2.9, 95% CI 1.7 to 4.8) and antibiotics (adjusted OR 2.3, 95% CI 1.8 to 3.1). The duration of use of these drug categories was short (range 1-8 days). Paracetamol showed a lower risk (adjusted OR 2.0, 95% CI 1.5 to 2.6) compared to ibuprofen (adjusted OR 3.7, 95% CI 2.3 to 5.9), although with partially overlapping CIs.

CONCLUSIONS

NSAIDs, oral steroids and antibiotics, even when administered for a short period, were associated with an increased risk of UGIC.

Rheumatologische und immunologische Krankheitsbilder

Eine Beeinträchtigung der gastrointestinalen Motilität findet sich im Rahmen rheumatologischer Erkrankungen insbesondere bei den chronisch-entzündlichen Bindegewebeerkrankungen und den systemischen Vaskulitiden. Je nach Krankheitsbild und verwandter Untersuchungsmethode variiert der Anteil der Patienten, bei denen eine gastrointestinale Symptomatik dokumentiert wird. Pädiatrische Daten sind bei diesen insgesamt seltenen Erkrankungen rar und umfassen in der Regel nur kleinere Fallserien. Eine gastrointestinale Beteiligung findet sich etwa bei 80–100 % der Patienten mit systemischer Sklerodermie, bei 60 % der Patienten mit einer „Mixed connective tissue disease“ oder einem CREST-Syndrom, etwa bei 50 % der Patienten mit einem Raynaud-Syndrom oder einer lokalen Sklerodermie und ungefähr bei 30 % der Patienten mit systemischem Lupus erythematodes oder juveniler Dermatomyositis.

Predictors of clinically significant upper gastrointestinal hemorrhage among children with hematemesis

OBJECTIVES

The aim of the study was to determine the proportion of children with hematemesis who experience a clinically significant upper gastrointestinal hemorrhage (UGIH) and to identify variables predicting their occurrence.

METHODS

A retrospective cohort study was conducted. All of the emergency department visits by children ages 0 to 18 years who presented with hematemesis between 2000 and 2007 were reviewed. The primary aim of the study was to determine the proportion of children who developed a clinically significant UGIH; the secondary aim was to identify risk factors predictive of a clinically significant UGIH. A significant UGIH was defined by any of the following: hemoglobin drop >20 g/L, blood transfusion, or emergent endoscopy or surgical procedure.

RESULTS

Twenty-seven of 613 eligible children (4%; 95% confidence interval 3%-6%) had a clinically significant UGIH. Clinically significant hemorrhages were associated with older age (9.7 vs 2.9 years; P<0.001), vomiting moderate to large amounts of fresh blood (58% vs 20%; P<0.001), melena (37% vs 5%; P<0.001), significant medical history (63% vs 24%; P<0.001), unwell appearance (44% vs 6%; P<0.001), and tachycardia (41% vs 10%; P<0.001). The frequency of laboratory investigations increased with age (P<0.001). The hemoglobin level was the only laboratory investigation whose results differed between those with and without significant bleeds. The presence of any one of the following characteristics identified all of the children with a clinically significant hemorrhage: melena, hematochezia, unwell appearance, or a moderate to large volume of fresh blood in the vomitus, sensitivity 100% (95% confidence interval 85%-100%).

CONCLUSIONS

The occurrence of a clinically significant UGIH was uncommon among children with hematemesis, especially in well-appearing children without melena, hematochezia, or who had not vomited a moderate to large amount of fresh blood.
