Vaginal infections in pregnancy are associated with considerable discomfort and adverse pregnancy outcomes including preterm delivery, low birth weight and increased infant mortality and also predisposition to HIV/AIDS. This study evaluated the prevalence and factors associated with vulvovaginal candidiasis, trichomoniasis and bacterial vaginosis among women attending antenatal clinic at a hospital in Nigeria. A semi-structured questionnaire was administered and high vaginal swab samples were obtained from consenting pregnant women. The samples were processed following standard protocols. The prevalence of vulvovaginal candidiasis was 36%, while those of trichomoniasis and bacterial vaginosis were 2% and 38%, respectively. Infections were higher in the third trimester and many women admitted to practices that increase risk of these infections. Significant association was found between recent intake of antibiotics and vaginal candidiasis, same association was also found with bacterial vaginosis. Adequate investigation and prompt treatment will reduce the morbidity and attendant effects of these prevalent infections on mother and fetus.
Human immunodeficiency virus-positive individuals are at increased risk of both asymptomatic and symptomatic urinary tract infections. The aim of this study was to determine the prevalence of asymptomatic bacteriuria (ASB) in HIV-positive individuals, its associated factors including any correlation with the CD4 count of the patient, and the antibiotic susceptibility pattern of the isolated organisms. Midstream urine and blood samples were collected from 242 consenting HIV-positive patients who were attending routine follow-up clinic during the six-month period of the study. Microscopy, culture, and antibiotic susceptibility testing of the samples were carried out following standard protocols, and CD4 counts were also determined. Fifty one (21.1%) of the 242 individuals had significant bacteriuria. The predominant organism was Klebsiella spp. (35%) followed by Escherichia coli (31%). Prevalence of bacteriuria was higher in the women. Low CD4 counts and young age were significantly associated with the presence of bacteriuria. ASB prevalence is high in this population and related to the CD4 count level.
The association of the HIV p24 antigen with blood donation was highly significant (p = 0.000) and pose a great risk to recipients if screening of blood donor is only carried out by HIV antibody detection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
