Asymptomatic Bacteriuria in Pregnant Women in the Antenatal Booking Clinic at Aminu Kano Teaching Hospital, Kano, Nigeria

Abstract

Asymptomatic bacteriuria is common in pregnant women and if untreated could lead to serious complications. Despite this, its prevalence and microbiological characteristics have not been well studied in Kano and they vary among different populations. The objective of the study was to determine the prevalence, microbiological characteristics and pregnancy outcome of asymptomatic bacteriuria in pregnancy among women who came for antenatal booking clinic at the Aminu Kano Teaching Hospital (AKTH) Kano. A cross sectional descriptive study was conducted among randomly selected 200 consenting pregnant women who came for antenatal booking from November 2010 to January 2011. Samples of 10-15 mls urine were examined for pus cells and bacteria and then cultured on cysteine lactose electrolyte deficient agar. Colony counts yielding bacterial growth of 105/ml or more of pure isolates were deemed significant. Isolates were identified to specie level. Antibiotic sensitivity test was done, treatment was given and pregnancy outcome was determined. Urinalysis and Full Blood Count were done. The prevalence of asymptomatic bacteriuria in pregnancy was 9%. Parity and Pyuria had statistically significant association with asymptomatic bacteriuria (P < 0.05). The commonest organisms isolated were Klebsiella spp. and Staphylococcus saprophyticus. Following treatment of asymptomatic bacteriuria, there was no statistically significant difference in pregnancy outcome compared to patients who did not have the condition. The incidence of asymptomatic bacteriuria in pregnancy in AKTH is low. Screening of pregnant women using urine microscopy culture and sensitivity should be reserved for pregnant women with higher risk of developing asymptomatic bacteriuria.

Prevalence, antimicrobial susceptibility profile and predictors of asymptomatic bacteriuria among pregnant women in Adigrat General Hospital, Northern Ethiopia

“…We noticed that the prevalence rate of ASB is varied in different studies. Our finding was found higher than other studies conducted in different parts of Ethiopia (10.6–11.5%) [ 27 , 32 , 33 ], and elsewhere in other African countries at (7.3–14.7%) [ 3 , 4 , 34 – 36 ], Chandanaish, Bangladesh at (13%) [ 5 ], and Sanandaj, Iran at (8.9%) [ 7 ]. However, our report was found almost comparable with other reports in Ethiopia that reported ASB between 16% and 18.9% [ 29 , 37 , 38 ] and abroad in Sagamu, Nigeria (23.9%) [ 39 ].…”

Prevalence of undiagnosed asymptomatic bacteriuria and associated risk factors during pregnancy: a cross-sectional study at two tertiary centres in Cairo, Egypt

“…The prevalence in this study is comparable to that reported in Nigeria, 14 but lower than studies from Ethiopia. [28][29][30][31] These discrepancies between and within countries may be due to differences in the study participants' socioeconomic levels, and cultural 7 and religious behaviours related to personal hygiene and sexual contact.…”

“…4 In contrast, a high proportion of S. saprophyticus was reported from Bahir Dar, Ethiopia (48.2%) 29 and Nigeria (44.5%). 3 In the current study, participants with the previous history of UTI had about 3 times chance of developing ASB (p=0.004). A similar finding was reported from Gondar, Ethiopia 30 and Egypt.…”

“…Urinary tract infection (UTI) is an infection of the urinary tract system; it can occur both in the community and hospital environment. 1,2 Even though all age groups are affected by UTI, pregnant women, [3][4][5] and immuno-compromised individuals 6 are more susceptible. Generally, women are at greater risk of UTI as compared to males because of anatomical position and short urethra.…”
