RESUMO

Cigarette smoking is a major public health issue in India and leads to significant morbidity and mortality. Addressing the issue of smoking is a major challenge to public health, as the addiction is hard to break. Counseling smokers regarding smoking cessation is the first step to achieving cessation, but the quit rates remain low. Several pharmacological interventions have been developed over the years. Nicotine replacement therapy is available in a variety of formulations, each with different advantages, drawbacks, acceptability among smokers and quit rates. In addition, a range of novel nicotine and tobacco products, including Heated Tobacco Products (HTPs), have been developed which leverage nicotine to aid in smoking cessation. A group of medical experts convened to review the evidence on the burden of smoking, the concept of Tobacco Harm Reduction (THR), novel nicotine and tobacco products for THR, and the potential of HTPs to aid in smoking cessation. This paper outlines the findings and recommendations regarding THR in the Indian context. The panel opined that tobacco cessation centers and counseling remain the foundation of tobacco cessation in India. At the same time, there appears to be potential for the application of THR products in India. The relevant authorities must review the potential of THR products, and make these available, to provide the best possible cessation strategy for the Indian population that is currently at risk of mortality and severe morbidity.

RESUMO

Background: Tuberculosis is global health problem known since ancient times. Drug-resistant TB has been known from the time of anti-TB drugs were first introduced for the treatment of TB. The emergence of drug resistant tuberculosis particularly MDR TB has become significant health problem worldwide and an obstacle to effective tuberculosis control. Line Probe Assay (LPA) is a Nucleic Acid Amplification Test (NAAT) which provides rapid diagnosis of R and H resistance and yield results in 72 hours.Literature on drug resistant pattern in patients who are previously treated for tuberculosis and/or suspected MDR cases with Line Probe Assay method are not studied hence this study was carried out. Aims and objectives: To know the drug resistance pattern of Rifampicin and Isoniazid in previously treated pulmonary tuberculosis cases and correlating with the demographic characteristics of patients. Methods: This study was carried out in department of Respiratory Medicine, Mahatma Gandhi Medical College and Hospital, Jaipur in AFB smear positive patients of pulmonary tuberculosis who have previously taken treatment, before reporting at OPD/IPD. The exclusion criterion was new cases of pulmonary tuberculosis. Detailed history, examination and investigations were carried out. The diagnosis of active pulmonary TB was based sputum smear examination by Ziehl - Nelson staining method. Sputum smear positive cases were subjected to line probe assay to detect resistant pattern at RNTCP accredited laboratory (SMS Medical College and Hospital, Jaipur). Results: A total of 175 previously treated sputum smear AFB positive patients of pulmonary tuberculosis were taken in this study. Out of which 141(80%) were males and 34(20%) cases were females with male : female ratio 4:1 and maximum cases (43.4%) belonged to 31-45 age group with mean age 38 years. Majority of cases belonged to rural area and lower middle class group. More than 2/3rd cases were smokers (72%) among male. Out of 175 cases, 100(57.1%) cases were drug resistant, 75(42.8%) cases were drug sensitive. Line probe assay with regard to resistant pattern was highest in grade +3 sputum (100%) followed by grade +2(98%) and grade +1(96%), while least in scanty sputum positive cases (3%). Resistance to Isoniazid (H), Rifampicin(R) and Both (H+R) were seen in 27%, 14% and 59% respectively. Half of patients (56%) out of total resistance belonged to default category of previously treated pulmonary tuberculosis cases. Resistance to H (27 cases) were 62.5% in relapse, 33.3% in default and 11% in failure cases. Out of R resistance (14 cases), 63% and 37% were in relapse and default cases. Out of 59 cases of H+R resistance 65% belonged to failure category and 20% default and 15% relapse category. Conclusion: Line Probe Assay (LPA) provides accurate and rapid diagnosis of R and H resistance and is recommended for diagnosis of DR-TB in previously treated pulmonary tuberculosis patients.

RESUMO

Beta-2-agonists continue to find a dominant role in all the current guidelines on the management of chronic persistent bronchial asthma. However, the safety of the drugs remains doubtful. Thus, there is a case for review of the “Step up-Step down” approach in the management of chronic persistent bronchial asthma. Based on the currently available experimental and clinical data on bronchial asthma, the authors are of the opinion that chronic persistent bronchial asthma is best managed by a modified “Step I-Step II” approach.
