High rate of rifampicin resistance of Mycobacterium tuberculosis in the Taif region of Saudi Arabia.
This retrospective study was undertaken to determine the prevalence and pattern of resistance to antituberculosis drugs among patients with sputum-proven pulmonary tuberculosis who were seen in Taif Chest Hospital over 24 months (between June 1986 and May 1988). The overall prevalence was 22.6% and the majority (53%) were resistant to two drugs. Resistance to streptomycin was most frequent (16%) followed by rifampicin (15%). Resistance to isoniazid was surprisingly low (6.5%). 23.3% of the resistant group had previously received antituberculosis drugs as against 15.4% in the sensitive group. There was a significant association between previous therapy and resistance to antituberculosis drugs. Recommendations to reduce the problem of resistance and to improve compliance are discussed.
