RESUMO
INTRODUCTION: The increased use of biologic drugs (BDs) may lead to an increase in immediate hypersensitivity reactions (I-HSRs) in pediatric patients with inflammatory bowel disease (IBD). Our aim was to assess I-HSRs to BDs in pediatric IBD, examining frequency, clinical features, management, and associated risk factors. METHODS: All children diagnosed with IBD at our institution between January 1, 2006, and August 1, 2023, and who developed I-HSRs related to any BD were included in the study. RESULTS: In a study of 197 pediatric IBD patients, 61 used BD. Among these, 52.4% were male, with a median diagnosis age of 145 months (13-215). Out of a total of 1,679 administrations, 6 patients developed I-HSRs (5 with infliximab, 1 with adalimumab), resulting in a frequency of 9.8% per patient and 0.36% per administration. Of these, 66.7% were cases of Type 1 HSRs (skin test positivity n = 1), while the rest were infusion-related reactions (anti-drug antibody positivity n = 4), all of which were mild to moderate in severity. In the age and gender-adjusted logistic regression model, the presence of any comorbid allergic disease was significantly associated with the occurrence of I-HSR (aOR = 8.35; 95% CI = 1.24-56.38; p = 0.029). CONCLUSION: The frequency of I-HSRs to BDs in children with IBD is not rare but not severe in the long term. The presence of any comorbid allergic disease is a risk factor for the development of I-HSRs to BDs.
RESUMO
Progressive familial intrahepatic cholestasis is a heterogeneous group of autosomal recessive disorders, and liver transplant is the only curative treatment. A biliary diversion operation for disruption of enterohepatic circulation in patients with progressive familial intrahepatic cholestasis type 1 without cirrhosis is another option. We present a pediatric patient with progressive familial intrahepatic cholestasis type 1 who underwent liver transplant due to end-stage liver disease. After transplant, diarrhea and growth retardation complications resolved after partial external biliary diversion surgery.

Ciliopathies are a heterogeneous group of diseases that are observed after deterioration of the ciliary structures on the cell surface that facilitate communication with the environment. Both liver and kidney involvement are frequently observed in this disease. Recently, a doublecortin domain containing protein 2 (DCDC2) mutation in a ciliopathy disease group was identified. Here, we present 2 patients with this mutation and with neonatal cholestasis and renal involvement.
