Renal Dysfunction in Patients With Inflammatory Bowel Disease and the General Population (NEPHRO-IBD)

The NEPHRO-IBD study is a multicenter prospective observational study designed to evaluate the prevalence of renal dysfunction and renal complications in adult patients with inflammatory bowel disease (IBD) compared with individuals from the general population. Although extraintestinal manifestations are common in IBD, renal involvement remains relatively underrecognized and insufficiently studied. The study will recruit approximately 6,000 participants, including 3,000 patients with confirmed IBD (Crohn's disease or ulcerative colitis) and 3,000 individuals without IBD serving as a control group. Participants will undergo routine clinical assessment, including laboratory tests, urinalysis with measurement of the albumin-to-creatinine ratio (ACR), and imaging evaluation of the kidneys and urinary tract. Disease activity in patients with IBD will be assessed using validated clinical indices. The study will also evaluate the relationship between renal dysfunction and disease activity, medications used in IBD treatment, and comorbidities. The results of this study are expected to improve the understanding of renal complications in patients with IBD and support earlier identification and management of kidney disease in this population.

Renal Involvement in Adult Patients With Inflammatory Bowel Disease and Its Relation to Duration and Disease Activity

To Assess the pattern of renal injury in patients with inflammatory bowel disease and its relation to the duration and disease activity by Identification and characterization of early renal manifestations (e.g., proteinuria, hematuria, electrolyte imbalances) in IBD patients. and know Correlation between kidney involvement and IBD severity, including flare-ups and complications. and know Impact of early renal manifestations on long-term renal outcomes, such as progression to CKD or development of AKI.
