Chlorine gas is one of the highly produced chemicals in the USA and around the world. Chlorine gas has several uses in water purification, sanitation, and industrial applications; however, it is a toxic inhalation hazard agent. Inhalation of chlorine gas, based on the concentration and duration of the exposure, causes a spectrum of symptoms, including but not limited to lacrimation, rhinorrhea, bronchospasm, cough, dyspnea, acute lung injury, death, and survivors develop signs of pulmonary fibrosis and reactive airway disease. Despite the use of chlorine gas as a chemical warfare agent since World War I and its known potential as an industrial hazard, there is no specific antidote. The resurgence of the use of chlorine gas as a chemical warfare agent in recent years has brought speculation of its use as weapons of mass destruction. Therefore, developing antidotes for chlorine gas-induced lung injuries remains the need of the hour. While some of the pre-clinical studies have made substantial progress in the understanding of chlorine gas-induced pulmonary pathophysiology and identifying potential medical countermeasure(s), yet none of the drug candidates are approved by the U.S. Food and Drug Administration (FDA). In this review, we summarized pathophysiology of chlorine gas-induced pulmonary injuries, pre-clinical animal models, development of a pipeline of potential medical countermeasures under FDA animal rule, and future directions for the development of antidotes for chlorine gas-induced lung injuries.

Trace elements and minerals are essential for cellular physiology and components of biological structures. Previous studies demonstrated that proper serum concentration of trace elements/minerals such as copper maintains optimum function of the immune system, and trace elements/mineral imbalance was associated with various autoimmune disorders. The current study aimed to measure the serum concentrations of trace elements/minerals potassium (K), sodium (Na), chlorine (Cl), calcium (Ca), phosphorus (P), iron (Fe), copper (Cu), and magnesium (Mg) in patients with diffuse systemic sclerosis (dSSc). Fifty-one patients with dSSc were enrolled in this study. Healthy 106 participants with similar age and gender to the patients were used as healthy control. Roche Cobas 8000 was used to measure the serum concentrations of K, Na, Cl, Ca, P, Fe, Cu, and Mg. The results demonstrated that the serum concentrations of K, Ca, P, and Mg were significantly increased in patients with dSSc, while the serum concentration of Cu was decreased. We next examined the serum concentration of trace elements/minerals in dSSc patients with or without pulmonary fibrosis. The result revealed that the serum concentration of Cu in dSSc patients with pulmonary fibrosis was significantly lower than that in patents without pulmonary fibrosis. Our study provided evidence that serum concentrations of K, Ca, P, Cu, and Mg were changed significantly in dSSc patients, and lower serum concentration of Cu was associated with pulmonary fibrosis.
