Introduction: Diabetes is a known risk factor for asymptomatic bacteriuria (ASB). However, the influence of diabetes on antenatal ASB was previously not addressed.
Aim: The prevalence of ASB, effect of risk factors and type of isolates and susceptibility patterns were studied in diabetic pregnancy. M aterials and Methods: A total of 311 pregnant women were recruited for this study of which 103 were diabetic and 208 non-diabetic. A clean catch midstream urine samples were collected and cultured. The isolates were identified and antibiotic sensitivity was studied. The data was analysed by Chi-square test.
Results: The prevalence of ASB in diabetic pregnancy was 38.83% (40/103; 95% CI: 23.73 - 53.94) and in non-diabetic pregnancy was 37.98% (79/208; CI: 27.28- 48.68). The odds ratio was not significant 1.0225 (95% CU: 0.65 – 1.599; p=0.922) and associated factors such as age and gestational period had no effect. The major isolates were Escherichia coli (25.0%), Staphylococcus aureus (22.5%), Coagulase negative staphylococci (CONS) (20.00%), and Klebsiella pneumonia (20.00%) in diabetic pregnancy and CONS (31.7%), E.coli (24.0%) and K.pneumonia (16.5%) in non-diabetic pregnancy. The isolates of diabetic pregnancy showed highest susceptibility to nitrofurantoin (56.4%), gentamicin (38.5%) and cotrimoxazole (38.5%) whereas that of non-diabetic pregnancy to gentamicin (43.0%), azithromycin (32.9%) and norfloxacin (30.4). There was no significant (p<0.05) difference in the type and susceptibly of the isolates between diabetic and non-diabetic pregnancy.
Conclusion: Diabetes has no significant influence on the prevalence of ASB in diabetic pregnancy both in terms of isolates and antibiotic susceptibility pattern.
