Covert bacteriuria in nephrotic syndrome.

Area of Science:

• Nephrology
• Infectious Diseases
• Urology

Background:

• Nephrotic syndrome is a kidney disorder characterized by heavy proteinuria, edema, and low serum albumin.
• Covert bacteriuria, the presence of bacteria in urine without symptoms, can complicate various medical conditions.
• Kidney biopsy is a crucial diagnostic tool for nephrotic syndrome, offering insights into underlying pathology.

Purpose of the Study:

• To determine the prevalence of covert bacteriuria in patients with nephrotic syndrome admitted for 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 undergoing kidney biopsy for nephrotic syndrome.
• Urine cultures were performed to detect bacteriuria.
• Serum albumin levels and 24-hour urinary protein excretion were measured.
• Histopathological findings from kidney biopsies were analyzed.

Main Results:

• Covert bacteriuria was detected in 18.53% (38/205) of patients.
• Escherichia coli was the most frequent pathogen, identified in 78.9% of bacteriuric cases.
• Bacteriuric patients exhibited significantly lower serum albumin and higher 24-hour urinary protein excretion compared to abacteriuric individuals.
• 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 poorer biochemical markers and specific kidney pathologies.
• Further investigation into screening and management strategies for covert bacteriuria in this population is warranted.
