Abstract:

Background: Urinary tract infections (UTIs) are among the most encountered bacterial infections of humans and affect both male and female of all age groups, resulting in high mortality, without proper management. This study aimed to assess the prevalence, aetiological agents, and factors associated with symptomatic significant bacteriuria/UTI among patients attending selected hospitals in Calabar metropolis, Nigeria.

Methodology: This was a cross-sectional study of 240 patients with suspected UTI, from whom mid-stream voided urine samples were collected for culture on Cystine Lactose Electrolyte Deficient (CLED) agar. Uropathogens growth on the culture media were characterized using conventional microbiological and biochemical tests, and confirmed with API® 20E and 20NE (BioMérieux) identification system. Data on socio-demographic, clinical symptoms and potential risk factors were obtained using structured questionnaire. Pearson Chi-square was employed to determine association between categorical variables with p<0.05 considered statistically significant.

Abstract

Differences are known to occur in prevalence rates in urinary tract infections (UTI) between men and women due to the difference between the urinary tracts of the sexes. Moreover, different organisms are known to infect and cause bacteriuria in men. When urine samples from 55 apparently healthy male students of Redeemer’s University were examined, nine bacteria species including Micrococcus luteus, Viellonella parvula, Micrococcus varians, Streptococcus downei, Streptococcus pneumonia, Bacillus subtilis, Streptococcus pyrogenes, Staphylococcus saprophyticus,and Enterococcus aquimarinus were isolated from the samples. The two most prevalent organisms reported in this study were Micrococcus luteus (40%) and Micrococcus varians (27.3%). The implication of the high prevalence rates (54.5%) of asymptomatic bacteriuria obtained in this population is discussed.

Abstract

Urinary tract infection (UTI) is a significant cause of morbidity and mortality in children, especially in those with sickle cell disease, who are at higher risk of infections. It will be useful to have a simple test which can be used in resource limited health facilities as a means of screening such children for UTI with the view to instituting prompt treatment. This study is carried out to determine the usefulness of significant pyuria in detecting UTI in febrile children with sickle cell anaemia (SCA). Two hundred and fifty febrile children with sickle cell anaemia that attended State Specialist Hospital and University of Maiduguri Teaching Hospital (UMTH) were prospectively studied with their consent. Urine sample was collected using standard procedure, examined for pus cells and was cultured at the Microbiology laboratory of UMTH. The study showed UTI prevalence of 26%. Significant pyuria was found to have sensitivity of 55.4%, specificity of 77.8%, the efficacy of the test was 72.0% and the test has low positive predictive value of 46.8% in detecting bacteriuria in SCA patients. The significant pyuria observed in this study support its usefulness in the diagnosis of UTI among children with SCA especially in communities having limited facilities or personnel for carrying out urine culture.
