Brief summary
This multicenter observational cross-sectional study aims to evaluate the prevalence of chronic kidney disease (CKD) in pediatric patients with inflammatory bowel disease (IBD) and to compare it with a control group without IBD. Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, are chronic conditions that can also affect organs outside the intestine. Among these, kidney involvement has been reported, but data in pediatric populations are limited. The study will collect clinical, laboratory, and demographic data from pediatric patients with IBD and matched controls without IBD. The main objective is to estimate the prevalence of CKD in children with IBD and compare it with that observed in the control group. Secondary objectives include describing patient characteristics and exploring potential associations between CKD, disease activity, and medical therapies. The results of this study may improve the understanding of kidney complications in pediatric IBD and support earlier diagnosis and better clinical management.
Detailed description
Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, are chronic relapsing conditions that frequently begin during childhood or adolescence. In pediatric patients, IBD often presents with more severe disease phenotypes and may be associated with extraintestinal manifestations involving multiple organ systems. Renal involvement is among the reported extraintestinal manifestations of IBD and includes a wide spectrum of conditions, such as nephrolithiasis, tubulointerstitial nephritis, glomerulonephritis, and chronic kidney disease (CKD). While these complications are relatively well described in adult populations, epidemiological data in pediatric patients remain limited, particularly in the Italian setting. Understanding the prevalence of CKD and its potential associations with disease activity and medical therapy is essential to improve early detection and long-term outcomes in pediatric patients with IBD.
Interventions
OTHERClinical and Laboratory Data Collection
Collection of anonymized clinical, demographic, laboratory, and therapeutic data from pediatric patients with inflammatory bowel disease (IBD) and matched controls. Data are collected through review of medical records and routine clinical assessments, including renal function evaluation (eGFR, creatinine, albuminuria), disease activity indices, and treatment history. No experimental intervention or modification of standard clinical practice is performed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Prevalence of Chronic Kidney Disease in Pediatric IBD Patients | At study enrollment (cross-sectional assessment) | Prevalence of patient with chronic kidney disease, compared with a matched control group without inflammatory bowel disease. Chronic kidney disease will be defined using estimated glomerular filtration rate (eGFR) calculated with the Schwartz formula and/or presence of albuminuria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Association Between Disease Activity and Chronic Kidney Disease | At study enrollment (cross-sectional assessment) | Assessment of the association between disease activity indices (e.g., PUCAI, PCDAI), laboratory parameters, and the presence of chronic kidney disease in pediatric patients with inflammatory bowel disease. |
