Asymptomatic bacteriuria (ASB) is common in pregnancy due to hormonal and physiological changes causing urinary stasis. ASB may cause maternal complications like Acute Pyelonephritis, PET, PROM, PPROM, PTL and foetal complications like LBW, IUGR and perinatal death.
This study was conducted to know the prevalence and outcome of ASB among antenatal women attending OPD in a tertiary care hospital. A total of 100 women with no clinical history of UTIs were included in the study for six months, followed up till delivery and discharge. Clean catch mid- stream urine was collected aseptically and processed by standard conventional bacteriological techniques. Out of 100 samples processed, 47 (47%) showed Significant bacteriuria (>105 CFU/ml) with infection rate of 47%. Organisms isolated were Staphylococcus aureus 15 (31.9%), Staphylococcus saprophyticus 8 (17.02%), Staphylococcus epidermidis 6 (12.76%), Enterococcus faecalis 5 (10.6%), Escherichia coli 9 (19.14%), Klebsiella sps 4 (8.5%), Micrococci 3 (6.38%). Maximum cases were in second trimester 25 (53.19%) followed by 3rd trimester 15 (31.9%) and 1st trimester 7 (14.89%). Women with positive cultures were administered antibiotics for 1 week and pregnancy was uneventful. In women with ASB in the last trimester, 10 (58.82%) developed maternal complications, 5 (29.41%) premature rupture of membranes, 2 (11.76%) puerperal pyrexia, 3 (17.64%) Threatened preterm labour, 1 case of PTL (1.85%) and foetal complication of Low birth weight. 53 (53%) women who are culture negative were without any maternal and foetal complications.
The present study concludes that undetected ASB leads to various maternal and foetal complications. Hence, it is mandatory to screen all antenatal women for ASB to initiate appropriate treatment so as to minimise maternal and foetal complications.
