The present study was undertaken to determine the drug resistance pattern of M. tuberculosis isolated from 225 pulmonary and 45 extrapulmonary tuberculosis cases. The samples were cultured on Lowenstein Jensen (L-J) media for isolation of M. tuberculosis. Drug resistance to first line anti tubercular drugsnamely isoniazid (INH), rifampicin (RIF), Ethambutol (ETH) and streptomycin (SM) were determined by indirect proportion method. The overall drug resistance of M. tuberculosis was 53.6% to any of the first line anti tubercular drugs. Rate of multi drug resistant tuberculosis (MDR-TB) among the untreated cases was 4.2%, while it was 36.0% in previously treated cases. It was found that 83.3% rifampicin resistant M. tuberculosis was cross resistant to one or more of other first line anti-tubercular drugs, while cross resistance of INH, ETH and SM resistant isolates was much low. The present study revealed that high level of drug resistance exists to individual anti tubercular drugs and MDR-TB is an emerging problem, particularly in treated cases. Rifampicin resistance could be used as a surrogate marker for drug resistance to other first line anti tubercular drugs.Ibrahim Med. Coll. J. 2014; 8(2): 41-46

Background: Anti-Tuberculosis (TB) drug resistance is emerging as a new global health problem. No national data on drug resistance is available in Bangladesh. The absolute number of multidrug resistant TB (MDR-TB) is expected to be high considering high TB burden. This study was aimed to determine the resistance pattern of mycobacterium tuberculosis (MTB) isolates among different category of patient. Method: A total 1123 randomly selected patients having clinical and or radiological features of tuberculosis attending out patients department of NIDCH were enrolled in this study during January to December, 2008. Sputum were collected and processed for culture by digestion, decontamination and concentration following modified Petroff's method and were inoculated on to two slopes of Lowenstein- Jensen (L-J) media for six weeks. The identity of the isolates was made by growth rate, colony morphology, P-nitrobenzoic acid (PNB) susceptibility, catalase and nitrate reduction tests. Ultimately drug susceptibility testing (DST) were performed. Result: Drug susceptibility testing for Isoniazid (INH), Rifampicin (RIF), Ethambutol (EMB) and Streptomycin (SM) was done among 363 cases. Resistance rates for INH, RIF, EMB and SM were 76.03%, 71.63%, 27.55% and 55.65% respectively. According to DST report, total 221 cases were detected as multi drug resistant TB (MDR-TB). Among them, 87% cases were MDR-TB in category II (CAT - II) failure and 13% were MDR-TB in category I (CAT - I) failure and it was 0% in new cases. Conclusion: Pattern of anti TB drug resistance was identified in this study. More surveillance and immediate therapeutic interventions should be performed in order to combat the threat of MDR-TB to the general population.

Background: Tuberculosis (TB) is a disease which has long been known and is still a cause of death in the world. The emergece of the drug resistance in TB treatment, particularly Multi drug-Resistance Tuberculosis (MDR TB) become a significant public health problem in many countries. The diagnosis of MDR TB based on culture results. In some cases radiographic feature with severe abnormalities consideres as MDR TB. From this phenomenon, there is no research that connects the resistance pattern of first line ATD with chest x-ray feature in patients with MDR TB. Methods: The research design are analytical observational with cross-sectional study conducted in outpatient clinic of MDR TB in Dr. Soetomo hospital. Subjects were patients who are following a theraphy program in outpatient clinic of MDR TB in Dr. Soetomo hospital from 2012 to 2014 who meet the inclusion and exclusion criteria. A total of 65 patients. Result: the result of this study showed that of all patterns of resistance, most of the MDR TB patients were classified as having severe chest radiograph. 27 patients with RH resistance patterns, there were 14(51.9%) who had a chest radiograph are classified as severe. 5 patients with RHS resistance patterns, 2(60%) vwho had a chest radiograph are classified as severe. 13 patients RHES resistance patterns, 8(61.5%) who had a chest radiograph are classified as severe. 20 patients with RHE resistance patterns, 14(70%) who had a chest radiograph are classified as severe. Conclusion: There were no significant association between resistance pattern of first line ATD and chest x-ray feature in patient with MDR TB.

Abstract Background A correlation between the CD4 counts and viral loads of HIV-1 infected North Indian patients with first line ART was reported. The follow up of fifty-seven patients were conducted after a confirmation genotypic test. The secondary data analysis was done on the data available to observe the correlation between the CD4 counts and viral loads (markers of clinical outcome) of HIV-1 Subtype C infected North Indian patients. Methods After analysis of the drug resistance mutations in individual patients through the drug resistance database, Stanford University, the data of resistance associated drugs, CD4 counts, viral load of individuals were compiled and analysed using Microsoft Excel 2016 and SPSS Version 22. Normality of data was checked by Shapiro-Wilk test (p < 0.05). Results Starting and study end point data on CD4 count, viral load and drug resistance pattern associated with multiple first line ART was available for 24 North Indian patients. Starting and study end point data on CD4 count and drug resistance pattern associated with multiple first line ART was available for 33 North Indian patients. Conclusion Our findings are categorically indicative that policy recommendation to provide tailor-made individualized regimen based on molecular drug resistance testing to HIV patients under AIDS control program requires robust evidence before implementation.

This study was designed to determine the extent of drug resistance of M. tuberculosis (MTB) isolated from category II treatment failure pulmonary tuberculosis (PTB) patients. A total of 100 Ziehl-Neelsen (Z-N) smear positive category II failure PTB patients were included in this study. Sputum culture was done in Lowenstein-Jensen (L-J) media. Conventional proportion method on Lowenstein-Jensen (L-J) media was used to determine the drug susceptibility of M. tuberculosis to isoniazid (INH), rifampicin (RMP), ofloxacin (OFX) and kanamycin (KA). Out of 100 sputum  samples, a total of 87 samples were positive by culture. Drug susceptibility test (DST) revealed that 82 (94.25%) isolates were resistant to one or more anti -TB drugs. Resistance to isoniazide (INH), rifampicin (RMP), ofloxacin (OFX) and kanamycin (KA) was 94.25%, 82.75%, 29.90% and 3.45% respectively. Among these isolates, 79.31% and 3.45% isolates were multi-drug resistant (MDR) and extended drug resistant (XDR) M. tuberculosis respectively. High rate of anti-tubercular drug resistance was observed among the category II treatment failure TB patients.DOI: http://dx.doi.org/10.3329/imcj.v7i1.17741 Ibrahim Med. Coll. J. 2013; 7(1): 9-11

Golestan Province

Purpose: The incidence of tuberculosis (TB) in Golestan province of Iran has been ranked 10th among countries of World Health Organization (WHO) Eastern Mediterranean Region. The province is residence of ethnically heterogeneous groups. However, there are limited data on Mycobacterium tuberculosis drug resistance in this province. The main aim of this study was to determine the resistance profile of M. tuberculosis complex (MTBC) isolates to first-line anti-TB drugs. Methods: The clinical specimens were collected from 11807 cases diagnosed during this study. MTBC isolates were tested for susceptibility to first-line anti-TB drugs. Results: A total of 176 new cases were diagnosed as culture positive for MTBC. There was one case that had multidrug-resistant (MDR) isolate and 18 (10.2%) had isolates that were resistant to at least one drug (any drug resistant). Resistance to streptomycin and isoniazid was noted in 15 (8.5%) and 5 isolates (2.8%), respectively. Also, a statistically significant association was observed between age groups and any drug resistance pattern (p = 0.022): 1-24 years vs. 25-45 years (p = 0.033), 25-45 years vs. >65 years (p = 0.010), 46-65 years vs. >65 years (p = 0.050). One third of any drug resistant isolates were obtained from TB patients of Persian ethnic group. Conclusion: Despite the high incidence of TB, the rate of MDR-TB in Golestan province was similar to those reported by WHO for Iranian new cases from other regions. One-tenth of the studied isolates showed any drug resistance pattern. This rate of any drug resistance implies the possibility of initial resistance of MTBC isolates circulating in this region.
