Outpatient Pain Management in Children With Chronic Pancreatitis: A Scoping Systematic Review.

OBJECTIVES: Although pain management is central to pediatric chronic pancreatitis (CP) care, no evidence-based guidelines exist. In this scoping systematic review, we sought promising strategies for CP pain treatment in children. METHODS: We systematically reviewed literature on pain management in children and adults with CP, and 2 conditions with similar pain courses: juvenile idiopathic arthritis and sickle cell disease. RESULTS: Of 8997 studies identified, 287 met inclusion criteria. There are no published studies of analgesic medications, antioxidants, dietary modification, integrative medicine, or regional nerve blocks in children with CP. In adults with CP, studies of nonopioid analgesics, pancreatic enzymes, and dietary interventions have mixed results. Retrospective studies suggest that endoscopic retrograde cholangiopancreatography and surgical procedures, most durably total pancreatectomy with islet autotransplant, improve pain for children with CP. Follow-up was short relative to a child's life. Large studies in adults also suggest benefit from endoscopic therapy and surgery, but lack conclusive evidence about optimal procedure or timing. Studies on other painful pediatric chronic illnesses revealed little generalizable to children with CP. CONCLUSIONS: No therapy had sufficient high-quality studies to warrant untempered, evidence-based support for use in children with CP. Multicenter studies are needed to identify pain management "best practices."

Vitamin D deficiency in pediatric patients with cystic fibrosis: associated risk factors in the northern United States.

OBJECTIVES: Cystic fibrosis (CF) is associated with vitamin D deficiency, which can lead to adverse effects including recurrent pulmonary infections and osteoporosis. We longitudinally investigated calcifediol or 25-hydroxyvitamin D (25(OH)D) levels for our pediatric patients with CF based on the time of year as well as vitamin D supplementation dosing ranges for these patients at our CF center. METHODS: We retrospectively evaluated vitamin D deficiency in our pediatric CF center for 2 years (baseline and annually) while evaluating 25(OH)D serum changes based on vitamin D supplementation, seasonality, patient age, and other factors associated with CF. RESULTS: Vitamin D supplementation was noted to be higher than current Cystic Fibrosis Foundation dosing recommendations, and no patient experienced vitamin D toxicity. Seasonality was a strong indicator of 25(OH)D levels, especially during summer or fall. Significantly fewer patients with initially low 25(OH)D levels maintained low levels at the conclusion of the study, suggesting benefit. Older patient age and higher supplemental dosing correlated with significantly lower 25(OH)D levels. CONCLUSIONS: This study suggests that targeted intervention among pediatric patients with CF living in northern latitudes of the United States, especially older children, is needed to prevent vitamin D deficiency.
