High-titer rheumatologic markers in serum of veterans with severe pulmonary complications 25-30 years after sulfur mustard exposure.

Sulfur mustard (SM), known as the "king of toxic agents," continues to pose a potential danger due to its ability to cause widespread damage, including ongoing corrosive effects. We aimed to determine the rheumatologic markers in SM veterans suffering from severe pulmonary manifestations. The serologic markers, including ANA, anti-DNA, rheumatoid factor (RF), and CRP, between SM-exposed veterans (n = 229) with severe problems and not-SM-exposed residents with no pulmonary disease history (n = 63), 25-30 years after SM exposure were compared.

Chemical exposure and alveolar macrophages responses: 'the role of pulmonary defense mechanism in inhalation injuries'.

Epidemiological and clinical studies have indicated an association between particulate matter (PM) exposure and acute and chronic pulmonary inflammation, which may be registered as increased mortality and morbidity. Despite the increasing evidence, the pathophysiology mechanism of these PMs is still not fully characterised. Pulmonary alveolar macrophages (PAMs), as a predominant cell in the lung, play a critically important role in these pathological mechanisms.

Impact of the MCP-1-2518A>G polymorphism on COVID-19 severity in the Iranian population: A case-control study.

As a result of SARS-CoV-2 infection, the host's immune system is disrupted, and chemokines and cytokines are intensified to eliminate the virus, resulting in cytokine storm syndrome and acute respiratory distress syndrome (ARDS). Patients with COVID-19 have been observed to have elevated levels of MCP-1, a chemokine associated with the severity of the disease. In some diseases, polymorphisms in the regulatory region of the MCP-1 gene correspond to serum levels and disease severity.
