Genomic revolution: Transforming tuberculosis diagnosis and treatment with the use of Whole Genome Sequencing - A consensus statement.

Tuberculosis (TB) is a preventable, treatable, and curable disease. However, in 2020, 9∙9 million people were estimated to have developed tuberculosis, and 1.5 million people were estimated to have died from it. Whereas in India, 2.6 million were diagnosed with TB and 436,000 succumbed to TB in 2019. India (26%) is the major contributor to the global drop in TB cases. The COVID-19 pandemic has substantially reduced access to services for the diagnosis and treatment of TB, resulting in an increase in deaths and a reversal in global progress. [1] Presently, TB incidence is falling at a rate of 2% per year, obstructed mainly by the rearing pandemic of drug-resistant tuberculosis (DRTB). Particularly concerning is multi-drug resistant TB (MDRTB), defined as resistance towards isoniazid (INH) and rifampicin (RIF). [2] The World Health Organization (WHO) targeted to reduce worldwide TB incidence by 90% until 2035. (1) Early initiation of effective treatment based on susceptibility patterns of the Mycobacterium tuberculosis complex (MTBC) is considered key to successful TB control in countries with high DRTB incidence. Worldwide MDRTB treatment outcomes are poor, with cure rates less than 60% (2) due to the lack of comprehensive Drug Susceptibility Testing (DST) in most high MDRTB burden countries. This is leading to the inadequate anti-TB activity of the provided regimens (3-5), unlike regimens advised for DST assure optimal results. (6) In addition to resistances to the established regimens, the resistance to the newer DRTB drugs is increasing. On World TB Day 2022, Academy of Advanced Medical Education, Thyrocare Technologies Limited and HyastackAnalytics - IITB along with expert pulmonologist and renowned physicians from India convened for an advisory board meeting in Delhi on 20th March 2022 to discuss the role of Whole Genome Sequencing (WGS) in the diagnosis and management of TB. Objectives and specific topics relating to WGS in MDRTB were discussed, each expert shared their views, which led to a group discussion with a commitment to putting the patient first, and increasing their collective efforts, the organizations recognized that it is possible to make this goal a reality. The organizations involved in the discussion have declared their commitment to engaging in collaborative efforts to tackle DRTB detection efficiently. They advocate for strengthening access to WGS TB services, controlling and preventing TB, improving surveillance and drug resistance management, and investing in research and development. This Round Table serves as a framework to build on and ensure that the goal of ending TB is achievable with WGS services wherever needed. Post discussion, a uniform consensus was said to be arrived if more than 80% board members agreed to the statement. The present paper is the outcome of aspects presented and discussed in the advisory board meeting.

Does inspiratory muscle training provide additional benefits during pulmonary rehabilitation in people with interstitial lung disease? A randomized control trial.

BACKGROUND: Interstitial lung disease (ILD) encompasses a diverse group of chronic lung conditions which is often characterized by inspiratory muscle weakness (IMW). Despite the potential importance of inspiratory muscle dysfunction in ILD, the effect of inspiratory muscle training (IMT) added to pulmonary rehabilitation (PR) in ILD largely remains unknown. OBJECTIVE: The primary objective of the present study was to evaluate the benefits of IMT added to PR on inspiratory muscle strength and secondary objectives were to assess its effects on functional capacity, health-related quality of life (HRQoL), pulmonary function test (PFT) and dyspnea in ILD along with IMW. METHODS: Fifty-one participants were randomly allocated into two groups; PR + IMT (n = 26) or PR alone (n = 25). The primary outcome [maximal inspiratory pressure (PImax)] and secondary outcomes [6-min walk distance (6MWD), St. George's Respiratory Questionnaire (SGRQ), PFT and modified Medical Research Council dyspnea scale (mMRC)] were evaluated before and after the 8-weeks intervention. Independent t-test or Mann Whitney-U test was applied for between-group comparisons while for within-group comparison Wilcoxon's Sign Rank test or paired t test was performed. RESULTS: At the end of 8 weeks exercise intervention inspiratory muscle strength (PImax + 11.10 cm H2O, p< .001), functional capacity (6MWD, + 47.90 m, p= .001), HRQoL (SGRQ-total - 4 points, p= .038) and dyspnea (mMRC dyspnea scale, -1.27, p< .001) improved significantly in PR+IMT group alone. CONCLUSION: Inclusion of IMT to PR may have superior benefits as compared to PR alone in ILD accompanied with IMW.

Use of single-inhaler triple therapy in the management of obstructive airway disease: Indian medical experts' review.

Obstructive airway disease (OAD), which includes COPD and asthma, is the leading cause of morbidity and mortality in India. Long-acting bronchodilators (long-acting ß2 agonists (LABAs) and/or long-acting muscarinic antagonists (LAMAs)) and inhaled corticosteroids (ICS) have a vital role in the management of patients with OAD. While symptom burden and exacerbations are common amongst treated patients, poor adherence to inhaler therapy is a frequent challenge. Better treatment options that optimise symptom control, improve quality of life, reduce exacerbation risk and improve adherence are desired. Triple therapy (ICS/LABA/LAMA) is recommended in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2021 guidelines for symptomatic COPD patients on ICS/LABA or LABA/LAMA, and who are at increased risk for frequent or severe exacerbations. Similarly, add-on LAMA is recommended in uncontrolled asthma patients on medium- to high-dose ICS/LABA by the Global Initiative for Asthma (GINA) 2021 guideline. In the real world, high-risk and overlapping phenotypes exist, which necessitate early initiation of triple therapy. We aim to provide an expert review on the use of single-inhaler triple therapy (SITT) for OAD management in global and Indian settings, knowledge from which can be extrapolated for appropriate treatment of Indian patients. The OAD population in India may benefit from early optimisation to SITT characterised by a high burden of exacerbating OAD, nonsmoker COPD and asthma-COPD overlap.
