Asymptomatic Bacteriuria in Pregnant Women

Abstract

Introduction: Asymptomatic bacteriuria is the significant presence of bacteria in urine of an individual without symptoms. The aim of the study is to determine the prevalence of asymptomaticbacteriuria in pregnant women.
 Methods: This study was a prospective study conducted in the department of Obstetrics and Gynaecology at B. P. Koirala Institute of Health Sciences. The duration of the study was six monthsfrom January to June 2012. A total of 600 pregnant women were enrolled. All women were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collectedfrom each patient into a sterile vial. The urine samples were examined for microscopic and culture sensitivity test.
 Results: Out of 600 pregnant women, 52 were positive for significant bacteriuria with a prevalence rate of 8.7%. There was a significant difference in prevalence of asymptomatic bacteriuria withrespect to trimester (p=0.005). Age did not show any significant difference in the prevalence of asymptomatic bacteriuria (p=0.807). There was not any significant difference in the prevalence ofasymptomatic bacteriuria with respect to parity (p=0.864) and booking status (p=0.397). Escherichia coli (35%), Acinetobacter species (15%), Enterococcus species (12%) and Klebsiella pneumoniae (10%)were the common isolates. Most of the isolates were sensitive either to Nitrofurantoin, Norfloxacin or Amikacin.
 Conclusions: Asymptomatic bacteriuria is common in pregnancy. Urine culture sensitivity should be carried out routinely on all pregnant patients in order to prevent the dangerous complicationsassociated with it.
 Keywords: asymptomatic bacteriuria in pregnancy; urine culture and sensitivity.

Prevalence of Asymptomatic Bacteriuria among Pregnant Women At Damietta Governorate, Egypt

“…Our results are consistent with most previous studies, in which Escherichia coli was the most commonly identified etiological factor of asymptomatic bacteriuria during gestation [8,13,19,29,32] . However, some studies found that is the commonest causative pathogen of asymptomatic bacteriuria in pregnant women is Klebsiella [12,24,37,38] .…”

“…These results are in accordance with some studies, which showed no significant difference in the incidence of asymptomatic bacteriuria with parity [13-15, 20, 30, 32, 33, 35, 40, 41] . However, other studies reported a significant association between the incidence of asymptomatic bacteriuria and increasing parity [12,21,26,29,42] .…”

“…Labi et al [33] and Izuchukwu et al [24] studies showed a higher incidence of asymptomatic bacteriuria among pregnant women aged 30-34 years. In Kehindo et al [25] and Rohini et al [29] studies, asymptomatic bacteriuria was most common among pregnant women of 25-30 year's age group.…”

“…In Rohini et al [29] study on 200 Indian pregnant women, 30.5% of them had asymptomatic bacteriuria. On the other side, some studies reported a lower incidence of asymptomatic bacteriuria among pregnant women than that in our work.…”

Infección Urinaria en Gestantes: Prevalencia y Factores Asociados en el Eje Cafetero, Colombia, 2018-2019

“…Respecto al tipo de infección urinaria más frecuente en los resultados del presente estudio, la prevalencia de bacteriuria asintomática es del 7,69%, resultado cercano al 8,7% encontrado en Dharan (Nepal) por Thakur y col., 31 ; aunque levemente mayor al 6,1% descrito por Ahmad y col., 32 en un grupo de 392 embarazadas en Srinagar, Kashmir (India); no obstante, en un reciente estudio publicado por Sandhya y col. 33 en el mismo país, se encontró una prevalencia ligeramente mayor (9,2%) en 250 gestantes. Con relación a la cistitis aguda, los hallazgos de este estudio, difieren del 1,3% reportado por Harris y col., 7 en el Centro médico Wilford Hall, San Antonio, Texas (EEUU), en una muestra de 9734 mujeres; así como al 54% descrito por Sanín-Ramírez y col., 34 en Medellín (Colombia), diferencia explicable porque las pacientes tenían síntomas de infección del tracto urinario.…”
