High prevalence of DR-TB (drug-resistant tuberculosis): An Indicator of public health negligence

Abstract

Tuberculosis (TB) is among the 10 most common worldwide causes of mortality. In Pakistan, estimated 510,000 tuberculosis patients had been diagnosed with an occurrence of 276/100,000. As per most recent global TB report 2018, Pakistan is amongst the 30 countries high TB with drug-resistant Mycobacterium tuberculosis particularly MDR (multi-drug resistant strains). A retrospective study had been designed using DR-TB patients’ records from January 2013 to the December 2017 year from a public sector hospital in Karachi. Overall 315 drug-resistant tuberculosis patient’s data had been incorporated in the study. All data had been analyzed using SPSS version 16 software. Chi-square test had been used to analyze the data with CI (confidence interval) 95% and level of significance 5%. The study result showed that 64.1% MDR patients, 27.9% MTB rifampicin resistance, 4.8% mono-drug resistant , XDR(1.6%), 1% poly-drug resistant and only 0.6% are MDR suspects showing no association of DR-TB with gender (pvalue 0.787), age group (p-value 0.757), treatment outcomes (p-value 0.549), year of registration( p-value 0.206), first line treatment history(p-value 0.643) with a 95% confidence interval. The drug resistance TB cases have been periodically rising every year. Early identification is required to reduce the percent mortality and inhibit the disease transmission.
