Background
Tuberculosis is a chronic disease with associated high morbidity and mortality. In recent decades, there has been an increase in resistance to drugs used in the treatment of tuberculosis. This is a major stumbling block in the global fight against tuberculosis. This study was to demonstrate the current prevalence of rifampicin-resistant tuberculosis and its associated predisposing factors in a Teaching Hospital in Nigeria.
Methods
This was a cross-sectional retrospective study involving 359 consecutive patients with bacteriologically confirmed tuberculosis seen between January 2015 and December 2019. Drug susceptibility testing was performed for rifampicin using GeneXpert MTB/RIF assay. Relevant information was obtained from the clinical records of the patients with the use of a well-structured proforma. The data obtained were analysed using the Statistical Package for Social Sciences (SPSS) version 23.0.
Results
There were a total of 359 patients out of which the majority, 235 (65.5%) were males. The mean age was 39.78+16.31 (range 1 - 90 years). A larger percentage of the subjects were new cases of tuberculosis (n=312, 86.9%), 49(13.6%) were HIV positive. The overall prevalence of rifampicin resistance found was 2.5% (n=9/359). There was a significant association between gender (p=0.005) and re-treatment (p=0.003). There was no significant association between rifampicin resistance and other factors including age and HIV.
Conclusion
Male gender and patients on re-treatment for tuberculosis are more at risk of developing resistance to rifampicin in our environment. There is a need to ensure compliance with all guidelines in the management of tuberculosis to prevent an increase in drug resistance.
