Association Between Central Obesity and Membranous Nephropathy.

Area of Science:

• Nephrology
• Metabolic Syndrome
• Public Health

Background:

• Global central obesity prevalence is rising.
• The association between central obesity and membranous nephropathy (MN) is not well understood.
• MN is a leading cause of nephrotic syndrome in adults.

Purpose of the Study:

• To investigate the impact of central obesity on the clinical and pathological features of membranous nephropathy.
• To determine if central obesity is a risk factor for severe outcomes in MN patients.

Main Methods:

• Retrospective cross-sectional study of 255 biopsy-proven MN patients.
• Central obesity assessed using waist-to-hip ratio (WHR).
• Clinical and pathological phenotypes evaluated through biochemical tests and renal pathology.

Main Results:

• Central obesity linked to more severe nephrotic syndrome and podocyte injury.
• Elevated 24-hour urine protein, cholesterol, triglycerides, and LDL in obese patients.
• Poorer renal function, increased glomerular damage, and worse lipid profiles observed with central obesity.

Conclusions:

• Central obesity is associated with adverse clinical and pathological outcomes in membranous nephropathy.
• Central obesity is a risk factor for massive proteinuria and severe podocyte injury.
• Managing central obesity may be crucial for improving MN prognosis.
