Covert bacteriuria in nephrotic syndrome.

Area of Science:

• Nephrology
• Infectious Diseases
• Urology

Background:

• Nephrotic syndrome is a kidney disorder characterized by proteinuria, edema, and hypoalbuminemia.
• Covert bacteriuria, the presence of bacteria in urine without symptoms, is a potential complication in various patient groups.
• Kidney biopsy is a diagnostic procedure for evaluating kidney diseases, including nephrotic syndrome.

Purpose of the Study:

• To determine the prevalence of covert bacteriuria in patients with nephrotic syndrome undergoing kidney biopsy.
• To identify common uropathogens and associated clinical and histopathological findings in bacteriuric patients.

Main Methods:

• A cross-sectional study was conducted on 205 patients with nephrotic syndrome admitted for kidney biopsy.
• Urine samples were analyzed for bacterial growth to detect bacteriuria.
• Clinical parameters (serum albumin, 24-hour urinary protein) and histopathological findings were assessed.

Main Results:

• Covert bacteriuria was detected in 18.53% (38/205) of patients.
• Escherichia coli was the most frequent organism (78.9%), predominantly in male patients.
• Bacteriuric patients exhibited lower serum albumin and higher 24-hour urinary protein excretion compared to abacteriuric patients.
• Membranous nephropathy was the most common histopathological finding (39.47%) among bacteriuric patients.

Conclusions:

• Covert bacteriuria is a significant finding in nephrotic syndrome patients undergoing kidney biopsy.
• The presence of bacteriuria correlates with specific clinical markers and kidney pathology.
• Further investigation into the management and implications of covert bacteriuria in this population is warranted.
