After admission to hospital, COVID-19 progresses in a substantial proportion of patients to critical disease that requires intensive care unit (ICU) admission. In a pragmatic, non-blinded trial, 387 patients aged 40-90 years were randomised to receive treatment with SoC plus doxycycline (n = 192) or SoC only (n = 195). The primary outcome was the need for ICU admission as judged by the attending physicians. Three types of analyses were carried out for the primary outcome: \"Intention to treat\" (ITT) based on randomisation; \"Per protocol\" (PP), excluding patients not treated according to randomisation; and \"As treated\" (AT), based on actual treatment received. The trial was undertaken in six hospitals in India with high-quality ICU facilities. An online application serving as the electronic case report form was developed to enable screening, randomisation and collection of outcomes data. Adherence to treatment per protocol was 95.1%. Among all 387 participants, 77 (19.9%) developed critical disease needing ICU admission. In all three primary outcome analyses, doxycycline was associated with a relative risk reduction (RRR) and absolute risk reduction (ARR): ITT 31.6% RRR, 7.4% ARR (P = 0.063); PP 40.7% RRR, 9.6% ARR (P = 0.017); AT 43.2% RRR, 10.8% ARR (P = 0.007), with numbers needed to treat (NTT) of 13.4 (ITT), 10.4 (PP), and 9.3 (AT), respectively. Doxycycline was well tolerated with not a single patient stopping treatment due to adverse events. In hospitalized COVID-19 patients, doxycycline, a safe, inexpensive, and widely available antibiotic with anti-inflammatory properties, reduces the need for ICU admission when added to SoC.

Background Mediastinal lymphadenopathy is seen in a variety of diseases, like tuberculosis, sarcoidosis, and metastasis. The diagnosis can be confirmed by tissue sampling with endobronchial ultrasound and transbronchial needle aspirate. A middle-aged male presented to us with a history similar to tuberculosis, and was on empirical anti-tuberculosis treatment was evaluated again by EBUS-TBNA and proved to be Rosai-Dorfman’s disease. This case report emphasizes on confirming the cases of mediastinal lymphadenopathy with tissue sampling. Conclusion All mediastinal lymphadenopathy should be evaluated in detail as the symptoms of the possible diseases, like tuberculosis, sarcoidosis, Kikuchi’s disease, Rosai-Dorfman’s disease, and malignancy can be similar. Hence, tissue sampling will confirm the diagnosis and help in appropriate management.

Background Spirofy™ is India’s first portable, pneumotach flow-sensor-based digital spirometer developed to diagnose asthma and chronic obstructive pulmonary disease (COPD). In this study, we compared the performance of the Spirofy™ device with that of the Vitalograph Alpha Touch™ spirometer in measuring the lung capacities of healthy individuals, asthmatics, and COPD patients. We also assessed the inter-device variability between two Spirofy™ devices. Methods In a randomized, three-way crossover, open-label study, we measured the differences in forced expiratory volume in the first second (FEV 1 ) and forced vital capacity (FVC) between the Spirofy™ and Vitalograph Alpha Touch™ spirometers. A proportion of the FEV 1 /FVC ratio distribution of < 0.7 was used to compare the diagnostic accuracies of the Spirofy™ with Vitalograph™ Alpha Touch™ spirometers. Results Ninety subjects participated in this study. The mean ± SD FVC values obtained from the Spirofy™ 1, Spirofy™ 2, and Vitalograph Alpha Touch™ devices were 2.60 ± 1.05 L, 2.64 ± 1.04 L, and 2.67 ± 1.04 L, respectively. The mean ± SD FEV 1 values obtained from the Spirofy™ 1, Spirofy™ 2, and Vitalograph Alpha Touch™ devices were 1.87 ± 0.92 (L), 1.88 ± 0.92 (L), and 1.93 ± 0.93 (L), respectively. A significant positive correlation was found between the FVC and FEV 1 values recorded by Vitalograph Alpha Touch™, Spirofy™ 1, and Spirofy™ 2. As compared to Vitalograph Alpha Touch™, the Spirofy™ device showed good sensitivity (97%), specificity (90%), and overall accuracy (93.3%) at an FEV 1 /FVC ratio < 0.7. No inter-device variability was observed between the two Spirofy™ devices. Conclusion Spirofy™ is a portable and easy-to-use device and is as accurate as the standard Vitalograph Alpha Touch™ spirometer for the diagnosis of COPD and asthma.

Blood eosinophils have become an invaluable tool in the assessment, management, and prognostication of patients with asthma and chronic obstructive pulmonary disease (COPD). Historically, the understanding and application of blood eosinophil counts (BEC) have been primarily based on data from high-income countries, with limited information available from developing regions, including the Indian subcontinent. This study aims to assess the distribution and clinical relevance of BEC among patients with asthma and COPD as well as healthy volunteers across India, to determine if patterns observed in Western studies hold true in an Indian setting. A multi-centre cross-sectional study was conducted at 16 clinics across India. Participants included patients diagnosed with asthma or COPD and healthy volunteers who were identified from referrals to these clinics. Comprehensive data collection involved demographics, medication use, smoking status, and pre- and post-bronchodilator spirometry. All participants underwent a laboratory full blood count. The study comprised 4782 adults, including 1,332 patients with asthma (571 males, 761 females), 1,001 patients with COPD (691 males, 310 females), and 2,449 healthy volunteers (1,399 males, 1,050 females). Among patients with asthma, the mean BEC was higher at geometric mean 173.9 [156.2, 193.6]; patients with COPD had a mean BEC of 198.4 [178.6, 220.4] which was significantly higher than that of healthy volunteers (144.7 [134.5, 155.5]). The range of eosinophils in the contemporary Indian population aligns with data from Europe, affirming the validity of using BEC as a biomarker in obstructive lung disease within the Indian demographic. This insight challenges the prevailing assumption of distinct eosinophil count profiles in different geographical regions and underscores the global applicability of eosinophil-based management strategies for asthma and COPD.

Background:Chronic respiratory diseases (CRDs) contribute significantly to morbidity and mortality worldwide and in India. Access to nonpharmacological options, such as pulmonary rehabilitation (PR), are, however, limited. Given the difference between need and availability, exploring PR, specifically remotely delivered PR, in a resource-poor setting, will help inform future work.Objective:This study explored the perceptions, experiences, needs, and challenges of patients with CRDs and the potential of and the need for PR from the perspective of patients as well as medical professionals involved in the referral (doctors) and delivery (physiotherapists) of PR.Methods:In-depth qualitative semistructured interviews were conducted among 20 individuals diagnosed with CRDs and 9 medical professionals. An inductive thematic analysis approach was used as we sought to identify the meanings shared both within and across the 2 participant groups.Results:The 20 patients considered lifestyle choices (smoking and drinking), a lack of physical activity, mental stress, and heredity as the triggering factors for their CRDs. All of them equated the disease with breathlessness and a lack of physical strength, consulting multiple doctors about their physical symptoms. The most commonly cited treatment choice was an inhaler. Most of them believed that yoga and exercise are good self-management strategies, and some were performing yoga postures and breathing exercises, as advised by friends or family members or learned from a televised program or YouTube videos. None of them identified with the term “pulmonary rehabilitation,” but many were aware of the exercise component and its benefits. Despite being naive to smartphone technology or having difficulty in reading, most of them were enthusiastic about enrolling in an application-based remotely delivered digital PR program. The 9 medical professionals were, however, reluctant to depend on a PR program delivered entirely online. They recommended that patients with CRDs be supported by their family to use technology, with some time spent with a medical professional during the program.Conclusions:Patients with CRDs in India currently manage their disease with nonguided strategies but are eager to improve and would benefit from a guided PR program to feel better. A home-based PR program, with delivery facilitated by digital solutions, would be welcomed by patients and health care professionals involved in their care, as it would reduce the need for travel, specialist equipment, and setup. However, low digital literacy, low resource availability, and a lack of expertise are of concern to health care professionals. For India, including yoga could be a way of making PR “culturally congruent” and more successful. The digital PR intervention should be flexible to individual patient needs and should be complemented with physical sessions and a feedback mechanism for both practitioners as well as patients for better uptake and adherence.

Considering a huge burden of chronic respiratory diseases (CRDs) in India, there is a need for locally relevant Pulmonary rehabilitation (PR) services. This cross-sectional survey was aimed to explore the interest, needs and challenges among various stakeholders for PR in Pune city, India. At the outpatient respiratory medicine department of a multi-speciality hospital in Pune, India, 403 eligible people with CRDs were invited to participate in the survey, of which 370 (92%) responded and agreed to participate. (220 males, mean ± SD age 56 ± 15 years). Out of the 370, 323 (87%) people with CRDs were keen to attend PR. In a multiple selection question, there was inclination towards paper-based manuals home-based (70%) and web-based (84%) programs. 207 healthcare providers (HCPs), including physicians, pulmonologists and physiotherapists involved in the care of people living with CRDs across Pune city were invited to participate in the survey. Out of the 207, (80%) of the HCPs believed that PR was an effective management strategy and highlighted the lack of information on PR and need for better understanding of PR (48%) and its referral process. The surveyed stakeholders are ready to take up PR, identifying specific needs around further knowledge of PR, modes of delivery, and referral processes, that could potentially feed the development of relevant PR programs in the Indian healthcare settings.
