Renal Behçet's disease: an update.

Area of Science:

• Nephrology
• Rheumatology
• Internal Medicine

Background:

• Behçet's disease (BD) is a multisystemic inflammatory disorder.
• Renal manifestations are a significant complication of BD, impacting patient prognosis.
• Understanding the spectrum of renal involvement in BD is essential for effective management.

Purpose of the Study:

• To document renal manifestations in 33 patients with Behçet's disease.
• To update the literature on renal involvement in BD by synthesizing data from current patients and published studies.

Main Methods:

• A comprehensive literature search was conducted on PubMed using terms related to BD and renal diseases.
• Data from 94 patients, including the study cohort, with BD and specific renal conditions were analyzed.
• Renal conditions included amyloidosis, glomerulonephritis (GN), renal vascular disease, and interstitial nephritis.

Main Results:

• Renal disease presentation varied, with edema/nephrotic syndrome in 36% of patients.
• In 61% of cases, renal disease was incidentally diagnosed via routine urine analysis and serum creatinine levels.
• Renal failure occurred in 70% of patients, with 5 receiving cyclosporine treatment.

Conclusions:

• Renal Behçet's disease exhibits a broad clinical spectrum, primarily involving AA amyloidosis, glomerulonephritis, and vascular disease.
• Vascular involvement in BD increases the risk of amyloidosis, a leading cause of renal failure.
• Early detection of renal BD through routine urinalysis and serum creatinine monitoring is recommended; treatment strategies require further evidence-based research.
