RESUMEN
OBJECTIVES: The primary objective was to investigate the mediating effects of patient-perceived medication adherence barriers in the relationship between gastrointestinal symptoms and generic health-related quality of life (HRQOL) in adolescents with inflammatory bowel disease (IBD). The secondary objective explored patient health communication and gastrointestinal worry as additional mediators with medication adherence barriers in a serial multiple mediator model. METHODS: The Pediatric Quality of Life Inventory™ Gastrointestinal Symptoms, Medicines, Communication, Gastrointestinal Worry, and Generic Core Scales were completed in a 9-site study by 172 adolescents with IBD. Gastrointestinal Symptoms Scales measuring stomach pain, constipation, or diarrhea and perceived medication adherence barriers were tested for bivariate and multivariate linear associations with HRQOL. Mediational analyses were conducted to test the hypothesized mediating effects of perceived medication adherence barriers as an intervening variable between gastrointestinal symptoms and HRQOL. RESULTS: The predictive effects of gastrointestinal symptoms on HRQOL were mediated in part by perceived medication adherence barriers. Patient health communication was a significant additional mediator. In predictive analytics models utilizing multiple regression analyses, demographic variables, gastrointestinal symptoms (stomach pain, constipation, or diarrhea), and perceived medication adherence barriers significantly accounted for 45, 38, and 29 percent of the variance in HRQOL (all Ps < 0.001), respectively, demonstrating large effect sizes. CONCLUSIONS: Perceived medication adherence barriers explain in part the effects of gastrointestinal symptoms on HRQOL in adolescents with IBD. Patient health communication to healthcare providers and significant others further explain the mechanism in the relationship between gastrointestinal symptoms, perceived medication adherence barriers, and HRQOL.

OBJECTIVES: The aim of the study was to investigate the multidimensional gastrointestinal symptoms predictors of generic health-related quality of life (HRQOL) in pediatric patients with inflammatory bowel disease from the perspectives of pediatric patients and parents. METHODS: The Pediatric Quality of Life Inventory Gastrointestinal Symptoms Scales and Pediatric Quality of Life Inventory 4.0 Generic Core Scales were completed in a 9-site study by 260 families of patients with inflammatory bowel disease. Gastrointestinal Symptoms Scales measuring stomach pain, food and drink limits, gas and bloating, constipation, blood in stool, and diarrhea were identified as clinically important symptom differentiators from healthy controls based on prior findings, and subsequently tested for bivariate and multivariate linear associations with overall HRQOL (Generic Core Scales). RESULTS: Stomach pain, food and drink limits, gas and bloating, constipation, blood in stool, and diarrhea were significantly associated with decreased HRQOL in bivariate analyses (Pâ<â0.001). In predictive models utilizing hierarchical multiple regression analyses controlling for age, sex, and race/ethnicity, gastrointestinal symptoms accounted for an additional 40% of the variance in patient self-reported HRQOL (Pâ<â0.001) and 37% of the variance in parent proxy-reported HRQOL (Pâ<â0.001), reflecting large effect sizes. Stomach pain, food and drink limits, and constipation were significant individual patient-reported predictors after controlling for the other gastrointestinal symptoms in the predictive models. CONCLUSIONS: Patient-reported gastrointestinal symptoms differentially predicted HRQOL. Identifying the specific gastrointestinal symptoms from a standardized multidimensional gastrointestinal symptoms profile that are the most important predictors from the patient perspective facilitates a patient-centered approach for interventions designed to ameliorate impaired HRQOL.

The differential diagnosis of abdominal pain is broad in any child, and further complicated in children with sickle cell disease (SCD). Acute causes of abdominal pain may require emergent surgery, such as for appendicitis or obstruction caused by a bezoar. Rapid intervention is necessary and life-saving in children with SCD and acute splenic or hepatic sequestration. The majority of children with SCD presenting to the physician's office or emergency department will have subacute reasons for their abdominal pain, including but not limited to constipation, urinary tract infection, peptic ulcer disease, and cholecystitis. Vaso-occlusive pain often presents in children as abdominal pain, but is a diagnosis of exclusion. The case of a 10-year-old girl with intermittent abdominal pain is used as a starting point to review the pathophysiology, diagnosis, and treatment of the most acute and common causes of abdominal pain in children with SCD.

Celiac disease (CD) is an autoimmune condition affecting the small intestine, triggered by the ingestion of gluten, the protein fraction of wheat, barley, and rye. There is a strong linkage between CD and HLA-DQ2 and HLA-DQ8 haplotypes. Multiple case reports and small series suggest concordance between CD and other autoimmune disorders. This paper provides a brief overview of the pathogenesis of CD and reviews the literature regarding associations between CD and other autoimmune diseases, including the potential effects of gluten-free diet therapy on the prevention or amelioration of associated diseases.

OBJECTIVE: Eosinophilic esophagitis (EoE) is a chronic esophageal inflammatory condition with a paucity of information on health-related quality of life (HRQOL). The objective of the study was to report on the measurement properties of the PedsQL EoE Module. METHODS: The PedsQL EoE Module was completed in a multisite study by 196 pediatric patients with EoE and 262 parents of patients with EoE. RESULTS: The PedsQL EoE Module scales evidenced excellent feasibility (0.6%-3.1% missing), excellent group comparison reliability across total scale scores (patient α 0.93; parent proxy α 0.94), good reliability for the 7 individual scales (patient α 0.75-0.87; parent proxy α 0.81-0.92), excellent test-retest reliability (patient intraclass correlation coefficient 0.88; parent intraclass correlation coefficient 0.82), demonstrated no floor effects and low ceiling effects, and demonstrated a high percentage of scaling success for most scales. Intercorrelations with the PedsQL Generic Core Scales were in the medium (0.30) to large (0.50) range. PedsQL EoE Module scores were worse among patients with active histologic disease (≥ 5 eos/hpf) compared with those in remission (patient self-report: 63.3 vs 69.9 [P < 0.05]; parent proxy report: 65.1 vs 72.3 [P < 0.01]), and those treated with dietary restrictions compared with those with no restrictions (patient self-report: 61.6 vs 74.3 [P < 0.01]; parent proxy report: 65.5 vs 74.7 [P < 0.01]). CONCLUSIONS: The results demonstrate excellent measurement properties of the PedsQL EoE Module. Patients with active histologic disease and those treated with dietary restrictions demonstrated worse PedsQL scores. The PedsQL EoE Module may be used in the evaluation of pediatric EoE disease-specific HRQOL in clinical research and practice.

Kaposi sarcoma (KS) of the gastrointestinal (GI) tract in a patient with acquired immunodeficiency syndrome (AIDS) has not been reported in an adolescent outside of Africa. We present a 16-year homosexual old male with AIDS, cutaneous KS, pulmonary KS, and gastrointestinal KS (GI-KS) lesions. Eighty percent of patients with GI-KS are asymptomatic, but our patient presented with a month-long history of dysphagia, abdominal pain, and hematochezia. Endoscopy with biopsies revealed multiple KS lesions within the stomach and lower GI tract. This novel case demonstrates the importance of considering early endoscopic screening in immunocompromised adolescents with cutaneous KS to improve morbidity and mortality.
