We found that the TB burden was lower than previously thought, which may indicate better programme performance. However, a high proportion of TB among young persons suggests that TB is circulating in the community and that there is a need for more efforts to limit the spread of TB disease.
Abstract. Tuberculosis (TB) is a major public health problem in Ethiopia and the Amhara region. Assessment of knowledge, attitude, and health-seeking practice in this region is essential to plan, implement, and evaluate advocacy, communication, and social mobilization work. This may improve the case detection rate. The aim of this study was to assess the knowledge, attitude, and practice of patients toward TB in the Eastern Amhara region of Ethiopia. A crosssectional survey was conducted among suspected and confirmed TB patients who were 18 years of age and older. For this purpose, 422 participants were enrolled. A structured and pre-validated questionnaire was used to collect data. In addition χ 2 and multivariate logistic regression analysis was used to see an association with different variables. The mean and median knowledge score of respondents about pulmonary TB was 6.81 and 7, respectively. The majority of respondents had several misconceptions in all aspects of the most infectious form of TB. About half of the respondents did not know the current free cost of TB diagnosis and treatment. The 69.9% of respondents claimed that cost is the main reason for not getting care. The majority of respondents had several misconceptions about TB. The TB control program needs to consider advocacy, communication, and social mobilization for addressing the gap in the study sites. BACKGROUND
BackgroundThe prevalence of drug resistant tuberculosis (TB) in Ethiopia in general, and Jimma area in particular, is not well documented. We conducted a study at Jimma University specialized hospital in southwest Ethiopia among new cases of smear positive TB patients to determine the pattern of resistance to first-line drugs.MethodsA health institution based cross sectional study was conducted from November 2010 to September 2011. Any newly diagnosed smear positive TB patient 18 years and above was included in the study. Demographic and related data were collected by trained personnel using a pretested structured questionnaire. Mycobacterial drug susceptibility testing (DST) to the first line drugs isoniazid (INH), rifampicin (RIF), ethambutol (EMB) and streptomycin (STM) was performed on cultures using the indirect proportion method. M. tuberculosis complex (MTBC) was identified with the Capilia TB-Neo test.Results136 patients were enrolled in the study. Resistance to at least one drug was identified in 18.4%. The highest prevalence of resistance to any drug was identified against INH (13.2%) followed by STM (8.1%). There was no statistically significant difference in the proportion of any resistance by sex, age, HIV status and history of being imprisoned. The highest mono resistance was observed against INH (7.4%). Mono resistance to streptomycin was associated with HIV infection (crude OR 15.63, 95%CI: 1.31, 187). Multidrug-resistance TB (MDR-TB) was observed in two patients (1.5%).ConclusionResistance to at least one drug was 18.4% (INH-13.2% and STM-8.1%). STM resistance was associated with HIV positivity. There was relatively low prevalence of MDR-TB yet INH resistance was common around Jimma. The capacity of laboratories for TB culture and DST should be strengthened, in order to correctly manage TB patients and avoid amplification of drug resistance.
Drug resistance is a major obstacle to effective TB control program performance. In this study, we assessed the prevalence of primary drug resistance in Mycobacterium tuberculosis (Mtb) isolates in Amhara Region, Ethiopia. A total of 112 Mtb isolates from cases with newly diagnosed pulmonary TB were subjected to drug susceptibility testing (DST) in a cross-sectional study. Isolates were tested for sensitivity to isoniazid, rifampicin, ethambutol, and streptomycin using the MGIT 960 protocol. A total of 93 Mtb isolates yielded valid DST results and 28 (30.1%) were resistant to one or more of first line anti-TB drugs. One isolate (1.0%) was multi-drug resistant (MDR), five (5.4%) were classified as poly-resistant and 22 showed single drug resistance to either streptomycin (n = 19) or isoniazid (n = 3). Isolates from HIV-positive patients were more likely to be resistant to at least one of the four anti-TB drugs compared with HIV-negative individuals (odds ratio 2.76, 95% confidence interval 1.06-7.22; p = 0.03). The study showed a high prevalence of primary drug resistance. Even though the prevalence of MDR was low, conditions that can contribute to the development of MDR are increasing. Therefore, regular monitoring of drug resistance and enhanced implementation of TB/HIV collaborative activities in the study region are imperative.
BackgroundThe identification of circulating TB strains in the community and drug sensitivity patterns is essential for the tuberculosis control program. This study was undertaken to identify M. tuberculosis strains circulating in selected communities in Ethiopia as well as to evaluate the drug sensitivity pattern of these strains.MethodThis study was a continuation of the Ethiopian National TB Prevalence Survey that was conducted between 2010 and 2011. Culture-positive isolates of M. tuberculosis from previous study were typed using region of difference (RD) 9-based polymerase chain reaction (PCR) and spoligotyping. Drug sensitivity testing was conducted using the indirect proportion method on Lowenstein-Jensen media.ResultAll 92 isolates were confirmed as M. tuberculosis by RD9-based PCR and spoligotyping of 91 of these isolates leds to the identification of 41 spoligotype patterns. Spoligotype revealed higher diversity (45 %) and among this 65.8 % (27/41) were not previously reported. The strains were grouped into 14 clusters consisting of 2–15 isolates. The dominant strains were SIT53, SIT149 and SIT37 consisting of 15, 11, and 9 isolates, respectively. Our study reveals 70 % (64/91) clustered strains and only 39.1 % (25/64) occurred within the same Kebele. Further assignment of the strains to the lineages showed that 74.7 % (68/91) belonged to Euro-American lineage, 18.6 % (17/91) to East Africa Indian lineage and the remaining 6.5 % (6/91) belonged to Indo-oceanic lineage. Valid drug susceptibility test results were available for 90 of the 92 isolates. Mono-resistance was observed in 27.7 % (25/90) and poly-resistance in 5.5 % (5/90) of the isolates. Moreover, multi-drug resistance (MDR-TB) was detected in 4.4 % of the isolates whilst the rest (60/90) were susceptible to all drugs. The highest level of mono-resistance, 26.6 % (24/90), was observed for streptomycin with majority (91.1 %) of streptomycin mono-resistant strains belonging to the Euro-American lineage.ConclusionIn this study, the strains of M. tuberculosis circulating in selected sites of Ethiopia were identified along with the drug sensitivity patterns. Thus, these findings are useful for the TB Control Program of the country.
