Molecular Diagnosis of Urinary Mycobacterium Tuberculosis Among Patients Attending Urology Clinic in Aminu Kano Teaching Hospital, Kano, Nigeria

Abstract

Background: Tuberculosis, a communicable disease with significant morbidity and mortality. It is still among the top killers of infectious diseases; Mycobacterium tuberculosis is a successful pathogen that has evolved several mechanisms to manipulate the host immune response. Objective of the study: The objective of this study was to determinethe prevalence of urinary tuberculosis among patients attending urology clinic in Aminu Kano Teaching Hospital, Kano, Nigeria. Materials and Methods: A prospective cross-sectional laboratory based study thatinvolved the use of questionnaire and consent/assent form prior to sample collection. Xpert MTB/Rif assay was used to analyze the urine samples. Results: The results of this study shows that, out of 71 samples analyzed along with positive control (H37RV) and molecular grade water was used as negative control. The results showed that, 2 (2.8 %) were from urine samples. Data generated were analyzed using descriptive statistics and results were presented in tables and charts. Conclusion: The study confirmed the presence of urinary tuberculosis in the study area, with prevalence of 2.8%. The pattern of tuberculosis was susceptible Mycobacterium tuberculosis. Therefore, there is need to introduce a routine screening of urinary tuberculosis among patients presenting sign and symptoms of urinary tract infection using Gene Xpert. This will be achieved through the engagement and enlightenment of the clinicians, strengthening the laboratory capacity for diagnosis and make the services available and accessible to the patients who need them.
