Asymptomatic pyuria in diabetic women

Area of Science:

• Urology
• Endocrinology
• Diabetology

Background:

• Asymptomatic pyuria (ASP) is a condition characterized by the presence of white blood cells in urine without urinary tract infection symptoms.
• Type 2 diabetes is associated with various complications, including microvascular damage, which may influence urinary tract health.
• Understanding the prevalence and risk factors for ASP in diabetic populations is crucial for managing potential urinary tract issues.

Purpose of the Study:

• To determine the prevalence of asymptomatic pyuria (ASP) in women with type 2 diabetes compared to non-diabetic women.
• To identify host factors associated with ASP in women with type 2 diabetes, including diabetes duration and microvascular complications.

Main Methods:

• A cross-sectional study involving 179 women with type 2 diabetes and 455 non-diabetic women.
• Exclusion of patients with symptomatic urinary tract infections.
• Definition of ASP as >10 leukocytes/high-power field in a random urine sample.

Main Results:

• Women with type 2 diabetes had a significantly higher prevalence of ASP (27.9%) than non-diabetic women (15.8%).
• ASP prevalence increased with longer diabetes duration, particularly over 15 years (46.3%).
• ASP was associated with increased severity of diabetic retinopathy, neuropathy, and nephropathy, but not with glycemic control (HbA1c).

Conclusions:

• Asymptomatic pyuria is more prevalent in women with type 2 diabetes and is linked to longer disease duration.
• The severity of diabetic microvascular complications, including retinopathy and nephropathy, correlates with a higher incidence of ASP.
• These findings highlight the importance of monitoring for urinary tract abnormalities in diabetic women, especially those with advanced complications.
