Prevalence of Gastroesophageal Reflux in Interstitial Lung Diseases Clinic.
Cureus
December 2024
Pulmonology, Jinnah Postgraduate Medical Centre, Karachi, PAK.
Background Interstitial lung diseases (ILDs) are a group of non-infectious diseases characterized by interstitial inflammation and fibrosis on histological examination. Gastroesophageal reflux disease (GERD) is common in this patient population, but whether there is a causal or coincidental relationship is not yet clear. It still remains unsettled how to diagnose GERD, and the role of different treatment modalities for GERD, in these lung disorders.

Background: The underlying pathophysiology of some occupational diseases such as silicosis involves autoantibodies. An autoantibody, antineutrophil cytoplasmic antibody (ANCA), has been recently reported and is known to be elevated in diseases such as vasculitis; therefore, the disease is currently known as ANCA-associated vasculitis. The risk of ANCA-associated vasculitis is known to be 25 times higher in patients with silicosis than in those without any occupational disease.

Background: Silicosis is a lung disease caused by the inhalation of free crystalline silica and is characterized mainly by lung inflammation and progressive pulmonary fibrosis. Shikonin, a biologically active compound isolated from the traditional Chinese medicine Comfrey, has been shown to have significant antifibrotic effects. However, the molecular mechanisms underlying the antifibrotic effects of SHK in silicosis remain unclear.

Indian Council of Medical Research-National Institute of Occupational Health, Ahmedabad, Gujarat 380016, India.
Background: Earlier studies conducted by Indian researchers have demonstrated that the elimination of tuberculosis (TB) requires proactive control of silicosis, given India's significant burden of silicosis and its common comorbidity, pulmonary TB, also known as silicotuberculosis. The TB Control Indian Health Authority saw human immunodeficiency virus infection, diabetes, and malnutrition, among others, as important risk factors for case findings, but overlooked the significance of silicosis. Silicotuberculosis control is often confronted with challenges of detecting microorganisms, uncertain treatment outcomes, a higher likelihood of mono-drug and multi-drug resistance, and increased mortality due to treatment failure.

bioRxiv
January 2025
Department of Immunology and Microbiology, Scripps Research, La Jolla, San Diego, USA.
Objective: The mucosal origin hypothesis in rheumatoid arthritis (RA) posits that inhalant exposures, such as cigarette smoke and crystalline silica (c-silica), trigger immune responses contributing to disease onset. Despite the established risk posed by these exposures, the mechanistic link between inhalants, lung inflammation, and inflammatory arthritis remains poorly understood, partly from the lack of a suitable experimental model. As c-silica accelerates autoimmune phenotypes in lupus models and is a recognized risk factor for several autoimmune diseases, we investigated whether c-silica exposure could induce RA-like inflammatory arthritis in mice.
