NCCP-ICS joint consensus-based clinical practice guidelines on medical thoracoscopy.

ABSTRACT: Medical Thoracoscopy (MT) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. The aim of the study was to provide evidence-based information regarding all aspects of MT, both as a diagnostic tool and therapeutic aid for pulmonologists across India. The consensus-based guidelines were formulated based on a multistep process using a set of 31 questions. A systematic search of published randomized controlled clinical trials, open labelled studies, case reports and guidelines from electronic databases, like PubMed, EmBase and Cochrane, was performed. The modified grade system was used (1, 2, 3 or usual practice point) to classify the quality of available evidence. Then, a multitude of factors were taken into account, such as volume of evidence, applicability and practicality for implementation to the target population and then strength of recommendation was finalized. MT helps to improve diagnosis and patient management, with reduced risk of post procedure complications. Trainees should perform at least 20 medical thoracoscopy procedures. The diagnostic yield of both rigid and semirigid techniques is comparable. Sterile-graded talc is the ideal agent for chemical pleurodesis. The consensus statement will help pulmonologists to adopt best evidence-based practices during MT for diagnostic and therapeutic purposes.

Pleural effusion guidelines from ICS and NCCP Section 1: Basic principles, laboratory tests and pleural procedures.

Pleural effusion is a common problem in our country, and most of these patients need invasive tests as they can't be evaluated by blood tests alone. The simplest of them is diagnostic pleural aspiration, and diagnostic techniques such as medical thoracoscopy are being performed more frequently than ever before. However, most physicians in India treat pleural effusion empirically, leading to delays in diagnosis, misdiagnosis and complications from wrong treatments. This situation must change, and the adoption of evidence-based protocols is urgently needed. Furthermore, the spectrum of pleural disease in India is different from that in the West, and yet Western guidelines and algorithms are used by Indian physicians. Therefore, India-specific consensus guidelines are needed. To fulfil this need, the Indian Chest Society and the National College of Chest Physicians; the premier societies for pulmonary physicians came together to create this National guideline. This document aims to provide evidence based recommendations on basic principles, initial assessment, diagnostic modalities and management of pleural effusions.

Guidelines for endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA): Joint Indian Chest Society (ICS)/Indian Association for Bronchology (IAB) recommendations.

Over the past decade, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an indispensable tool in the diagnostic armamentarium of the pulmonologist. As the expertise with EBUS-TBNA has evolved and several innovations have occurred, the indications for its use have expanded. However, several aspects of EBUS-TBNA are still not standardized. Hence, evidence-based guidelines are needed to optimize the diagnostic yield and safety of EBUS-TBNA. For this purpose, a working group of experts from India was constituted. A detailed and systematic search was performed to extract relevant literature pertaining to various aspects of EBUS-TBNA. The modified GRADE system was used for evaluating the level of evidence and assigning the strength of recommendations. The final recommendations were framed with the consensus of the working group after several rounds of online discussions and a two-day in-person meeting. These guidelines provide evidence-based recommendations encompassing indications of EBUS-TBNA, pre-procedure evaluation, sedation and anesthesia, technical and procedural aspects, sample processing, EBUS-TBNA in special situations, and training for EBUS-TBNA.

Conventional flexible bronchoscopy during the COVID pandemic: A consensus statement from the Indian Association for Bronchology.

During the times of the ongoing COVID pandemic, aerosol-generating procedures such as bronchoscopy have the potential of transmission of severe acute respiratory syndrome coronavirus 2 to the healthcare workers. The decision to perform bronchoscopy during the COVID pandemic should be taken judiciously. Over the years, the indications for bronchoscopy in the clinical practice have expanded. Experts at the Indian Association for Bronchology perceived the need to develop a concise statement that would assist a bronchoscopist in performing bronchoscopy during the COVID pandemic safely. The current Indian Association for Bronchology Consensus Statement provides specific guidelines including triaging, indications, bronchoscopy area, use of personal protective equipment, patient preparation, sedation and anesthesia, patient monitoring, bronchoscopy technique, sample collection and handling, bronchoscope disinfection, and environmental disinfection concerning the coronavirus disease-2019 situation. The suggestions provided herewith should be adopted in addition to the national bronchoscopy guidelines that were published recently. This statement summarizes the essential aspects to be considered for the performance of bronchoscopy in COVID pandemic, to ensure safety for both for patients and healthcare personnel.

Clinical practice guidelines 2019: Indian consensus-based recommendations on influenza vaccination in adults.

Influenza, a common cause of acute respiratory infections, is an important health problem worldwide, including in India. Influenza is associated with several complications; people with comorbidities and the elderly are at a higher risk for such complications. Moreover, the influenza virus constantly changes genetically, thereby worsening therapeutic outcomes. Vaccination is an effective measure for the prevention of influenza. Despite the availability of global guidelines on influenza vaccination in adults, country-specific guidelines based on regional variation in disease burden are required for better disease management in India. With this aim, the Indian Chest Society and National College of Chest Physicians of India jointly conducted an expert meeting in January 2019. The discussion was aimed at delineating evidence-based recommendations on adult influenza vaccination in India. The present article discusses expert recommendations on clinical practice guidelines to be followed in India for adult influenza vaccination, for better management of the disease burden.

Clinical practice guidelines 2019: Indian consensus-based recommendations on pneumococcal vaccination for adults.

Similar to the global scenario, pneumococcal diseases are a significant health concern in India. Pneumococcal diseases occur frequently among adults and are largely preventable through vaccines. Globally, several guidelines and recommendations are available for pneumococcal vaccination in adults. However, owing to wide variations in the disease burden, regulatory landscape, and health-care system in India, such global guidelines cannot be unconditionally implemented throughout the country. To address these gaps, the Indian Chest Society and National College of Chest Physicians of India jointly conducted an expert meeting in January 2019. The aim of the discussion was to lay down specific evidence-based recommendations on adult pneumococcal vaccination for the country, with a view to further ameliorate the disease burden in the country. This article presents an overview of the closed-door discussion by the expert members on clinical practice guidelines to be followed for adult pneumococcal vaccination in India.

Management of interstitial lung diseases: A consensus statement of the Indian Chest Society (ICS) and National College of Chest Physicians (NCCP).

BACKGROUND: Interstitial lung disease (ILD) is a complex and heterogeneous group of acute and chronic lung diseases of several known and unknown causes. While clinical practice guidelines (CPG) for idiopathic pulmonary fibrosis (IPF) have been recently updated, CPG for ILD other than IPF are needed. METHODS: A working group of multidisciplinary clinicians familiar with clinical management of ILD (pulmonologists, radiologist, pathologist, and rheumatologist) and three epidemiologists selected by the leaderships of Indian Chest Society and National College of Chest Physicians, India, posed questions to address the clinically relevant situation. A systematic search was performed on PubMed, Embase, and Cochrane databases. A modified GRADE approach was used to grade the evidence. The working group discussed the evidence and reached a consensus of opinions for each question following face-to-face discussions. RESULTS: Statements have been made for each specific question and the grade of evidence has been provided after performing a systematic review of literature. For most of the questions addressed, the available evidence was insufficient and of low to very low quality. The consensus of the opinions of the working group has been presented as statements for the questions and not as an evidence-based CPG for the management of ILD. CONCLUSION: This document provides the guidelines made by consensus of opinions among experts following discussion of systematic review of evidence pertaining to the specific questions for management of ILD other than IPF. It is hoped that this document will help the clinician understand the accumulated evidence and help better management of idiopathic and nonidiopathic interstitial pneumonias.

Pneumococcal disease burden from an Indian perspective: Need for its prevention in pulmonology practice.

Globally, pneumococcal diseases are a significant public health concern. They are preventable and frequently occur among older adults. Major risk factors for the disease are extremes of age, alcohol intake, smoking, air pollution, and comorbid conditions (diabetes, chronic obstructive pulmonary disease, chronic kidney disease, liver disease, and heart disease). Risk factors, coupled with limited disease-burden data and the emergence of antibiotics resistance, are hindering the effective management of the disease in older adults. Various global guidelines recommend pneumococcal vaccines for the prevention of pneumococcal diseases, as they reduce disease burden, hospitalization, and mortality rates among patients with comorbid conditions. Besides being an integral part of childhood immunization, these vaccines are advocated by various Indian healthcare bodies/groups for older and younger adults with certain medical conditions. The article presents an overview of the closed-door discussion by the Indian pulmonary experts on the scientific evidence and clinical practice followed for the prevention of pneumococcal disease in India.

Six versus 12 Months of Anti Tubercular Therapy in Patients With Biopsy Proven Spinal Tuberculosis: A Single Center, Open Labeled, Prospective Randomized Clinical Trial-A Pilot study.

STUDY DESIGN: A single center pilot study, open labeled, prospective randomized clinical trial. OBJECTIVE: To compare six versus 12 months of anti TB therapy in patients with biopsy proven spinal TB. SUMMARY OF BACKGROUND DATA: There is no clear consensus or evidence based guidelines for the duration of treatment of spinal tuberculosis. We studied if 6 and 12 months of anti tubercular therapy (ATT) had equivalent outcomes at 24 months from completion of therapy. METHODS: A prospective randomized open labeled clinical trial of 6 versus 12 months ATT in patients with biopsy proven spinal-vertebral tuberculosis. The primary end point was absence of recurrence 24 months after completing therapy. Secondary end points were clinical cure at the end of therapy, significant adverse effect of ATT, need for delayed surgery, and residual neurological dysfunction. RESULTS: Hundred patients, randomized to 6 or 12 months ATT, were followed up for a minimum of 24 months from completion of therapy. All patients completed scheduled duration of ATT, with one crossover from 6 months ATT group to 12 months. There were no recurrences of disease on the 24 months follow up following completion of ATT. All 100 patients met criteria for cure at time of stopping medicines. One patient (12 months group) had residual neurological dysfunction at the time of stopping treatment, which completely resolved over the next 12 months.There were no patients with major drug induced hepatitis. One patient (12 months group) needed percutaneous drainage of an abscess. None needed surgical re-exploration for persistent infection of implant removal. CONCLUSION: This pilot study concludes that, in patients with biopsy proven spinal-vertebral, TB, 6 and 12 months of ATT give similar clinical outcomes at 24 months of completion of therapy. LEVEL OF EVIDENCE: 2.

Hemoptysis due to Tracheal Diverticulum.

Tracheal diverticulum is a rare entity with only 79 symptomatic cases reported till date. We herein describe the case of a 38 year old male who presented with recurrent dry cough and hemoptysis and was diagnosed to have tracheal diverticulum on High Resolution Computed Tomography (HRCT) of chest. This was further confirmed on fibre optic bronchoscopy.

Drug resistance patterns in 111 cases of drug-resistant tuberculosis spine.

PURPOSE: We report the largest study conducted till date of drug resistant tuberculosis in spine analyzing the drug susceptibility patterns in 111 cases of proven drug resistance. METHODS: An observed cross-sectional study was conducted. Six-hundred and eighty-six patients with positive cultures underwent sensitivity testing to 13 commonly used anti-tubercular drugs using BACTEC MGIT-960 system. RESULTS: Females (60.3%) outnumbered males (39.6%). Only three patients (2.7%) were found HIV positive, and none of these had AIDS. Forty-four (39.6%) patients had taken AKT in the past for some form of tuberculosis. Eight (7.2%) patients had history of treatment default. The drug sensitivity testing revealed 87 (78.3%) cases of multi drug resistance (resistance to both isoniazid and rifampicin) and 3 (2.7%) cases of XDR-TB spine. Of the individual drugs, widespread resistance was present to both isoniazid (92.7%) and rifampicin (81.9%), followed by streptomycin (69.3%). Least resistance was found to kanamycin, amikacin and capreomycin. CONCLUSION: It is recommended to do routine biopsy, culture and drug sensitivity testing in all patients of tuberculosis spine to guide selection of appropriate second-line drugs when required. In cases of non availability of drug susceptibility testing despite repeated attempts, it is suggested to use data from large series such as this to plan best empirical chemotherapy protocol.

Multidrug-resistant tuberculosis of the spine--is it the beginning of the end? A study of twenty-five culture proven multidrug-resistant tuberculosis spine patients.

STUDY DESIGN: Prospective cohort study. OBJECTIVE: We report the first study of multidrug-resistant tuberculosis (MDR-TB) in the spine. The aim was to determine the clinical, radiologic, and drug resistance profile as well as the factors associated with treatment outcome of MDR-TB in the spine. SUMMARY OF BACKGROUND DATA: Tuberculosis of the spine is the most common extrapulmonary form of tuberculosis in the Asian subcontinent. The disease in few cases is resistant to the primary anti-Koch's medications and the number of cases detected is on the rise. Multidrug resistant form of tuberculosis of the spine is ill reported in the literature. The diagnosis, management thus remains a challenge to the treating surgeon. This study tries to assess these critical issues of this "new" disease. METHODS: Described here are the clinical characteristics of 25 MDR-TB spine patients identified in the study and their drug susceptibility patterns. They were followed up clinically, radiologically after a biopsy, culture, and Drug Susceptibility Testing. According to their Drug Susceptibility Testing pattern and previous history of Anti-Tubercular Treatment (ATT), individualized treatment regimens were tailored for each patient by an expert physician. RESULTS: Majority of the patients seen in the present study were in the productive years of their life. (Males (9) mean age: 38.5 years and females (16) mean age: 34.3 years. Four patients were defaulters of the ATT. The average number of drugs used was 6, including 4 second line drugs. Average treatment duration was 24 months. Almost 50% of the patients had adverse drug effects. Of the 25 patients, 19 achieved healed status and 6 are still on treatment. Four patients required surgery for mechanical instability of the spine. Radiologic improvement was observed in all the cases after a mean treatment of 6 months. Five predictors were identified for successful outcome of MDR-TB. They include progressive clinical improvement at 6 months, radiologic improvement during treatment and disease with Mycobacterium tuberculosis strains exhibiting resistance to less than or up to 3 antitubercular drugs, use of less than or up to 4 second-line drugs in treatment, and no change of regimen during treatment. CONCLUSION: MDR-TB of the spine is a different disease and is here to stay. There is an urgent need to include culture and drug susceptibility testing in the protocol for the treatment of tuberculosis of the spine.
