In the present study the most common pattern observed is MDR with predominant resistance to INH. There is a rise in the number of drug resistant tuberculosis cases, especially MDR. Hence close monitoring of drug resistant pattern is required to formulate designs of different regimens in the treatment of drug resistant tuberculosis; especially MDR-TB based on accredited laboratory reports, in a specialized center which is very much essential for the betterment of the patients and the community.
Objectives:To study the ongoing inflammatory process of lung in healthy individuals with risk factors and comparing with that of a known diseased condition. To study the inflammatory response to treatment.Background:Morbidity and mortality of respiratory diseases are raising in trend due to increased smokers, urbanization and air pollution, the diagnosis of these conditions during early stage and management can improve patient's lifestyle and morbidity.Materials and Methods:One hundred subjects were studied from July 2010 to September 2010; the level of hydrogen peroxide concentration in exhaled breath condensate was measured using Ecocheck.Results:Of the 100 subjects studied, 23 were healthy individuals with risk factors (smoking, exposure to air pollution, and urbanization); the values of hydrogen peroxide in smokers were 200-2220 nmol/l and in non-smokers 340-760 nmol/l. In people residing in rural areas values were 20-140 nmol/l in non-smokers and 180 nmol/l in smokers. In chronic obstructive pulmonary disease cases, during acute exacerbations values were 540-3040 nmol/l and 240-480 nmol/l following treatment. In acute exacerbations of bronchial asthma, values were 400-1140 nmol/l and 100-320 nmol/l following treatment. In cases of bronchiectasis, values were 300-340 nmol/l and 200-280 nmol/l following treatment. In diagnosed pneumonia cases values were 1060-11800 nmol/l and 540-700 nmol/l following treatment. In interstitial lung diseases, values ranged from 220-720 nmol/l and 210-510 nmol/l following treatment.Conclusion:Exhaled breath condensate provides a non-invasive means of sampling the lower respiratory tract. Collection of exhaled breath condensate might be useful to detect the oxidative destruction of the lung as well as early inflammation of the airways in a healthy individual with risk factors and comparing the inflammatory response to treatment.
Aims and Objectives. To study the pattern of drug-resistance and treatment outcomes among patients with confirmed multidrug-resistant pulmonary tuberculosis (MDR-PTB). Methods. A prospective study was conducted at
Background: Diffuse parenchymal lung diseases (DPLDs) have gone through various changes in nomenclature and classification since they were first described in 1868. Increasing knowledge about their etiopathogenesis has since led to several reclassifications and changes in the nomenclature. This has had a major impact on the prevalence of each interstitial lung disease (ILD) reported by the different registries worldwide. In this study, we attempted to describe the distribution of the different DPLDs in our population and reported changes in prevalence due to changing diagnostic criteria for the disease. Materials and methods:We analyzed retrospective data of 434 patients. For the initial 75 patients, ATS/ERS guidelines published in 2002 were followed in the diagnosis of the ILD (group I). In the later part of the study (359 patients), the diagnosis was based on the computed tomography (CT) patterns defined by ATS/ERS/JPS/ALAT statement on diagnosis of idiopathic pulmonary fibrosis (IPF) and updated 2013 ATS/ ERS guidelines (group II). Results: Of the 75 patients in group I, IPF was the most common diagnosis (52%) made at that time, followed by sarcoidosis and connective tissue-related ILD (CTD-ILD) with 12% each. Group II had 359 patients, with IPF again being the most commonly diagnosed ILD with 21.3%. This was followed by CTD-ILD (18.6%), sarcoid (14.7%), and idiopathic nonspecific interstitial pneumonitis (iNSIP; 13.3%). The changing guidelines have an impact on reporting of different DPLD by our multidisciplinary teamover a period of time. Though IPF was the most commonest DPLD reported among both the groups, the diagnosis of IPF had fallen by more than half in the second group. It was paralleled by an increase in the diagnosis of iNSIP and chronic hypersensitivity pneumonitis. These reported changes in the prevalence of DPLDs may reflect the better-defined criteria in the latest guidelines and a better understanding of the fibrotic ILDs other than IPF by the multidisciplinary team. Conclusions: The frequency of diagnosis of the different DPLDs has changed, following the publication of several guidelines in the last decade. It has recognized newer entities with greater clarity, such as idiopathic NSIP and interstitial pneumonia with autoimmune features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
