Psychological characteristics of caregivers of pediatric patients with chronic rheumatic disease in relation to treatment adherence

The evaluation of depression and anxiety levels of mothers of patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome and familial Mediterranean fever

OBJECTIVE

Periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome and familial Mediterranean fever (FMF) are autoinflammatory disorders typically characterized by recurrent fever attacks. These recurrent fever attacks can lead to depression and anxiety in mothers of these patients. This study aimed to compare the depression and anxiety levels in mothers of PFAPA and FMF patients.

METHODS

This study is a cross-sectional observational study. 48 mothers of children with FMF and 70 mothers of children with PFAPA participated in the study. Mothers in these two groups were compared in terms of anxiety and depression by using the validated Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI).

RESULTS

Depression and anxiety scores of mothers were found to be similar in FMF and PFAPA groups. Moderate or high level of anxiety was seen in 32% of mothers of patients with PFAPA and 27% of mothers of patients with FMF. 23% of mothers of patients with PFAPA were evaluated as having moderate or severe depression, and 18% of mothers of patients with FMF were evaluated as having moderate depression. There was no statistically significant difference between the duration, frequency of attacks, recurrent hospitalizations, sociodemographic characteristics, and inventory scores.

CONCLUSION

Depression and anxiety scores of mothers with children diagnosed with FMF and PFAPA are similar. These two diseases affect families psychosocially at similar levels. It is important to provide psychosocial support to families.

Factors associated with medication adherence among children with rheumatic diseases

Introduction: Failure to take medications regularly leads to poorer health outcomes. The Pediatric Rheumatology Adherence Questionnaire (PRAQ) is an effective tool for assessing medication adherence in rheumatic patients. Therefore, we aimed to determine the factors associated with poor medication adherence among children with rheumatic diseases. Methods: This was a cross-sectional study. Patients with rheumatic diseases who had taken at least one medication and had been followed up at our pediatric rheumatology clinic were included in the study, together with their caregivers. Patients with poor medication adherence were characterized as those who had taken less than 80% of their prescribed drugs, as determined using the pill count method. The original PRAQ was translated and validated in Thai language and was completed by caregivers and literate patients over age 13 years. Interviewing for additional problems with taking medications was conducted. We performed descriptive and logistic regression analyses. Results: From 210 patients, 52.86% had juvenile idiopathic arthritis (JIA), and 46.19% had connective tissue diseases. The mean patient age was 14.10 ± 4.74 years, with a median (interquartile range) disease duration of 4.33 (2.08-6.98) years. PRAQ scores in the group with poor adherence were significantly higher than scores in the group with good adherence (11.00 ± 3.47 vs. 9.51 ± 3.16, p = 0.004). Enthesitis-related arthritis (ERA) (odds ratio [OR] 9.09, 95% confidence interval [CI] 1.25-66.18; p = 0.029) and polyarticular JIA (OR 6.43, 95% CI 1.30-31.75; p = 0.022) were associated with poor treatment adherence. Disease duration ≥5 years (OR 3.88, 95% CI 1.17-12.87; p = 0.027), active disease (OR 6.49, 95% CI 1.76-23.99; p = 0.005), PRAQ scores ≥12 (OR 6.48, 95% CI 1.76-23.82; p = 0.005), forgetting to take medications (OR 14.18, 95% CI 4.21-47.73; p < 0.001), and unawareness about the importance of the medicines (OR 44.18, 95% CI 11.30-172.73; p < 0.001) were predictors of poor drug adherence. Conclusion: In the present study, poor medication adherence was found in one-fourth of children with rheumatic illnesses, particularly those with ERA, polyarticular JIA, longer disease duration, active disease, and high PRAQ scores. The most frequent reasons for inadequate medication adherence were forgetfulness and unawareness about the importance of disease control and consistency with treatment.

Hydroxychloroquine and immunosuppressant adherence patterns and their association with subsequent hospitalization rates among children with systemic lupus erythematosus

OBJECTIVES

Using a representative sample of children with systemic lupus erythematosus (SLE) in the United States, we characterized prescription claim-based hydroxychloroquine and immunosuppressant adherence estimates and evaluated their concurrent and predictive validity.

METHODS

We identified children ages 5-18 with SLE in the Truven Health MarketScan® Commercial and Medicaid claims databases (2013-2018). Among new users of hydroxychloroquine and immunosuppressant medications, we calculated proportion of days covered (PDC) over 365 days to estimate adherence by user group (mycophenolate, azathioprine, methotrexate, and any immunosuppressant use). Agreement between adherence estimates was evaluated with intraclass correlation coefficients (ICC) and kappa statistics. Separate negative binomial regression models were used to estimate associations between (a) hydroxychloroquine, (b) immunosuppressant, or (c) concurrent immunosuppressant/hydroxychloroquine non-adherence and subsequent hospitalizations, adjusted for baseline demographics, disease severity, and healthcare utilization.

RESULTS

Among 423 new hydroxychloroquine/immunosuppressant users, 63% were Medicaid recipients. Sufficient adherence (PDC≥80%) ranged from 33 to 45% for immunosuppressants vs. 51-52% for hydroxychloroquine. Agreement between hydroxychloroquine and immunosuppressant adherence was modest overall, but better for mycophenolate (ICC 0.55) than methotrexate (0.27). Hydroxychloroquine non-adherence was associated with a 2.9-fold higher incidence of subsequent hospitalizations (95% CI [1.2-7.1]), whereas immunosuppressant and concurrent non-adherence were associated with 5.9 [2.4-14.6] and 5.6-fold [2.0-15.5] increased incidence, respectively. Use of concurrent adherence improved upon estimation of hospitalization risk compared to hydroxychloroquine adherence, but not immunosuppressant adherence alone.

CONCLUSIONS

Hydroxychloroquine adherence is an imperfect proxy for adherence to other lupus medications among children with SLE, and therefore assessing immunosuppressant adherence concurrently adds value to hydroxychloroquine adherence assessments. Prescription claims-based immunosuppressant adherence measures are predictive of acute care utilization and may inform population management strategies.

Predictors of adherence to positive airway pressure therapy in children: a systematic review and meta-analysis

BACKGROUND

While positive airway pressure (PAP) is effective for treating sleep-disordered breathing (SDB) in children, adherence is poor. Studies evaluating predictors of PAP adherence have inconsistent findings, and no rigorous reviews have been conducted. This systematic review aims to summarize the literature on predictors of PAP therapy adherence in children.

METHODS

Studies evaluating baseline predictors of PAP therapy adherence in children (≤20 years) with SDB were included. We searched MEDLINE, Embase, CENTRAL, CINAHL, Clinicaltrials.gov, and the last four years of conference abstracts. Results were described narratively, with random-effects meta-analyses performed where feasible. Risk of bias and confidence in the evidence were assessed.

RESULTS

We identified 50 factors evaluated across 28 studies (21 full text articles, seven abstracts). The highest rates of PAP therapy adherence were most consistently found with female sex, younger age, Caucasian race, higher maternal education, greater baseline apnea-hypopnea index (AHI), and presence of developmental delay. Pooled estimates included odds ratios of 1.48 (95%CI: 0.75-2.93) favoring female sex, 1.26 (95%CI: 0.68-2.36) favoring Caucasian race, and a mean difference in AHI of 4.32 (95%CI: -0.61-9.26) events/hour between adherent and non-adherent groups. There was low quality evidence to suggest that psychosocial factors like health cognitions and family environment may predict adherence.

CONCLUSION

In this novel systematic review, we identified several factors associated with increased odds of PAP therapy adherence in children. These findings may help guide clinicians to identify and support children less likely to adhere to PAP therapy and should be considered when developing interventions to improve adherence.
