Nat2 Gene

Drug resistant TB is currently a global challenge causing high risk of death and expanding the disease. This study explores the prevalence of drug resistance in newly diagnosed and recurrent TB patients and identifies the association between NAT2 gene polymorphism distribution and acetylator phenotype of NAT2 gene and the two study groups. The study results show that the newly diagnosed TB had l lower male ratio and younger age in comparison to the recurrent TB. Newly diagnosed group was more sensitive to first line TB drugs. However, both groups had significant resistance ratio in relation to INH and SM. Finally, the allele and acetylator phenotype frequency of NAT2 showed the significant association with TB status. The study concludes that the newly diagnosed and recurrent TB patients expressed differently in their profiles concerning patient’s background, drug resistance and NAT2 allele distribution.

The aim of the study was to determine compliance in 260 newly diagnosed patients with infiltrative pulmonary tuberculosis using a screening test questionnaire developed by the authors. Low efficiency of treatment in patients with low compliance, the transition of the tuberculous process into a chronic form, the formation of drug resistance in them was established. The conclusion is made about the effectiveness of the developed technique for determining compliance in tuberculosis patients.

The aim of the study was to estimate spread of primary and secondary multiple drug resistant Mycobacterium tuberculosis (MBT) and to characterize rpoB, katG, inhA, and ahpC gene mutations of rifampicin (RIF) and isoniazid (INH) resistant MBT strains isolated from tuberculosis patients in Kyrgyz. We obtained 493 specimens from patients with pulmonary tuberculosis which were diagnosed based on clinical, X-ray, and bacteriological examination. Among them, newly diagnosed pulmonary tuberculosis was in 445 patients (90.2 %), and 48 of the patients (9.8 %) have already been treated for tuberculosis. Mutations of rpoB, KatG, inhA, and ahpC genes associated with RIF and INH resistance were detected by biological chip test. Sensitive MBT strains were detected in 47 % and resistant strains were in 53 % of the newly diagnosed patients. Single-drug resistance to RIF only was detected in 3 % of cases; resistance to INH was found in 20 %, resistance to both the drugs was detected in 30 % of the patients. In pre-treated patients single-drug resistance to RIF was defined in 4 % of cases, resistance to INH was in 8 %, resistance to both the drugs was estimated in 75 % of the patients. Therefore, we suppose that there is a high prevalence of multi-drug resistant MBT in Kyrgyz Republic: 30 % among newly diagnosed patients and 75 % among pre-treated patients. The main cause of RIF-resistance of MBT is Ser531→Leu mutation of rpoB gene, and the main cause of INHresistance is Ser315→Thr mutation of katG gene.

Background: Oxidative stress may play an important role in the pathogenesis of pulmonary tuberculosis (PTB). To our knowledge there is paucity of data on the status of oxidative stress biomarkers among PTB patients in Gombe, North-eastern Nigeria. Our study was designed to evaluate the oxidative stress biomarkers in pulmonary tuberculosis patients in Gombe, North-eastern Nigeria. Aims and Objectives: To determine the serum levels of oxidative stress biomarkers among patients with pulmonary tuberculosis in Gombe metropolis, North-eastern Nigeria and to assess the correlation between the oxidative stress biomarkers in pulmonary tuberculosis patients. Materials and Methods: A cross sectional comparative study was conducted in a tertiary health care facility with 40 pulmonary tuberculosis (PTB) patients on anti-TB drugs treatment (ATT), 40 newly diagnosed PTB patients not yet on anti-TB drugs treatment (ATT-naïve) and 40 age- and sex-marched apparently healthy subjects (controls). Serum total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), nitric oxide (NO) and oxidative stress index (OSI) determined using standard techniques. Data was analysed using INSTAT® (Graph Pad Software Inc., La Jolla, CA, USA). Results: Serum levels of TOS, OSI, MDA and NO were significantly (p ˂ 0.001) increased in PTB patients (ATT and ATT-naïve) when compared with healthy individuals. Serum TAS and body mass index (BMI) were significantly (p ˂ 0.001) decreased in PTB patients when compared with healthy individuals. Serum TOS significantly correlated with serum OSI, MDA and NO in ATT-naïve PTB patients. Conclusion: This study observed an increased oxidative stress biomarkers and decreased total antioxidant status in newly diagnosed pulmonary tuberculosis patients and those on treatment. Our findings suggest that antioxidants supplementation and improved nutrition in the management of pulmonary tuberculosis patients may go a long way in preventing the oxidative onslaught and further complications in PTB patients.
