Clinical Significance of Aspergillus Sensitisation in Chronic Pulmonary Aspergillosis.

Objective: Aspergillus sensitisation (AS) is seen in many patients with chronic pulmonary aspergillosis (CPA). However, the clinical relevance of AS in CPA remains unclear. In this study, we assess the clinical significance of AS in CPA.

Five principles and protocols for the clinician based on the 2021 ERS and BTS statements for treating sarcoidosis.

The European Respiratory Society (ERS) and the British Thoracic Society (BTS) have recently published their statements on the treatment of sarcoidosis. There are five key questions in sarcoidosis treatment that need to be addressed: when to treat, how to initiate treatment, how long to treat, when and how to change treatment, and how to treat relapses. Herein, we describe the principles and protocols to answer these questions based on the ERS and BTS statements and other expert reviews.

Indian Rheumatology Association guidelines for the management of ANCA associated vasculitis.

Background: The ACR in 2021 and the EULAR in 2022 published recommendations for management of ANCA-associated vasculitis. Given the differences in the demographic, clinical profiles, and the socio-economic realities between various countries, there is a need for development of guidelines for the management of AAV for less economically developed regions of the world.

Methods: These guidelines were made following the GRADE methodology.

Common single nucleotide polymorphisms associated with idiopathic pulmonary fibrosis: a systematic review.

Background: Several genetic variants are associated with the risk of idiopathic pulmonary fibrosis (IPF). These have not been systematically reviewed.

Methods: We searched the PubMed, Embase and GWAS Catalog databases for studies indexed between inception and 15 January 2024 describing genetic variants associated with IPF susceptibility.

Evaluating Lung Changes in Long COVID: Ultra-Low-Dose vs. Standard-Dose CT Chest.

Background: Frequent chest CTs within a short period during follow-up of long COVID patients may increase the risk of radiation-related health effects in the exposed individuals. We aimed to assess the image quality and diagnostic accuracy of ultra-low-dose CT (ULDCT) chest compared to standard-dose CT (SDCT) in detecting lung abnormalities associated with long COVID.

Methods: In this prospective study, 100 long COVID patients with respiratory dysfunction underwent SDCT and ULDCT chest that were compared in terms of objective (signal-to-noise ratio, SNR) and subjective image quality (image graininess, sharpness, artifacts, and diagnostic accuracy along with the European guidelines on image quality criteria for CT chest), detection of imaging patterns of long COVID, CT severity score, and effective radiation dose.

Chemokine receptor CXCR4 based positron emission tomography imaging in systemic sclerosis-related interstitial lung disease.

Objective: To assess chemokine receptor CXCR4 expression in lung parenchyma and on peripheral immune cells in systemic sclerosis-related interstitial lung disease (SSc-ILD) patients.

Methods: SSc-ILD patients underwent 68Ga- CPCR4 Trifluoroacetate positron emission tomography (PET) scan, SUVmean in different lung regions and architecturally abnormal areas, and receiver operating characteristic (ROC) curves were analyzed. CXCR4 expression on peripheral immune cells using flow cytometer was studied and correlated with the different lung regions.

The minimal important difference of one-minute-sit-to-stand test in subjects with chronic pulmonary aspergillosis.

Background And Objective: There is a need for simple functional test to assess treatment response in chronic pulmonary aspergillosis (CPA) in resource-constrained settings. The one-minute-sit-to-stand test (1-min-STS) is one such test. However, the minimal important difference (MID) for 1-min-STS in subjects with CPA remains unknown.

Role of serial fluorodeoxyglucose positron emission tomography-computed tomography (18FDG-PET-CT) in assessing treatment response in treatment naïve chronic pulmonary aspergillosis subjects.

Background: The role of 2-deoxy-2-18(F) fluoro-D-glucose (FDG) positron emission tomography (PET)-computed tomography (CT) in assessing treatment response in chronic pulmonary aspergillosis (CPA) remains to be determined.

Objective: To compare changes in FDG-PET/CT parameters in CPA subjects with treatment success or failure.

Methods: We treated consecutive treatment-naïve CPA subjects with six months of oral itraconazole.

Population prevalence of aspergillus sensitization and allergic bronchopulmonary aspergillosis in COPD subjects in North India.

Background: Sensitization to Aspergillus fumigatus (AS) has been recently described in chronic obstructive pulmonary disease (COPD) patients. However, there is no data on the community prevalence of AS in COPD.

Objectives: To assess the prevalence of AS among COPD subjects.

A Randomized Control Trial Comparing the Yield of Bronchoalveolar Lavage Using Three Different Techniques in Patients Undergoing Flexible Bronchoscopy (BAL-3T).

Background: Three techniques have been described for aspirating the bronchoalveolar lavage (BAL) fluid, namely the wall mount suction (WMS), manual suction (MS), and manual suction with tubing (MST). However, there is no direct comparison among the 3 methods.

Methods: We randomized patients undergoing flexible bronchoscopy and BAL in a 1:1:1 ratio to one of the 3 arms.

Chest CT Findings at Six Months Following COVID-19 ARDS - Correlation With the mMRC Dyspnea Scale and Pulmonary Function Tests.

Many survivors of severe COVID-19 pneumonia experience lingering respiratory issues. There is limited research on follow-up chest imaging findings in patients with COVID-19 ARDS, particularly in relation to their mMRC dyspnea scores and pulmonary function tests (PFTs). This study addresses this gap by investigating the clinical characteristics, mMRC dyspnea scores, PFTs, and chest CT findings of COVID-19 ARDS patients at the 6 months post-recovery.

Pulmonary Langerhans Cell Histiocytosis: Diagnosis in Bronchoalveolar Lavage Liquid-Based Cytology Samples.

Introduction: Pulmonary Langerhans cell histiocytosis (PLCH) is a rare interstitial lung disease characterized by the accumulation of Langerhans cells within the lung tissue. The diagnosis of PLCH traditionally involves clinical, radiological, and lung biopsy histopathological evaluations.

Case Presentation: We present 2 cases where the diagnosis of PLCH was confirmed through the analysis of bronchoalveolar lavage (BAL) fluid cytology using immunoperoxidase technique, highlighting the significance of this minimally invasive technique in the diagnostic process.

Innate and adaptive immune responses in subjects with CPA secondary to post-pulmonary tuberculosis lung abnormalities.

Background: Post-tuberculosis lung abnormality (PTLA) is the most common risk factor for chronic pulmonary aspergillosis (CPA), and 14%-25% of the subjects with PTLA develop CPA. The pathogenesis and the host immune response in subjects with PTLA who develop CPA need to be better understood.

Methods: We prospectively compared the innate and adaptive immune responses mounted by patients of PTLA with or without CPA (controls).

Bronchial Valves for Persistent Air Leak: A Systematic Review and Meta-analysis.

Background: Patients with persistent air leak (PAL) pose a therapeutic challenge to physicians, with prolonged hospital stays and high morbidity. There is little evidence on the efficacy and safety of bronchial valves (BV) for PAL.

Methods: We systematically searched the PubMed and Embase databases to identify studies evaluating the efficacy and safety of BV for PAL.

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.
