Mustard gas (sulfur mustard [SM], bis-[2-chloroethyl] sulfide) is a vesicating chemical warfare agent and a potential chemical terrorism agent. Exposure of SM causes debilitating skin blisters (vesication) and injury to the eyes and the respiratory tract; of these, the respiratory injury, if severe, may even be fatal. Therefore, developing an effective therapeutic strategy to protect against SM-induced respiratory injury is an urgent priority of not only the US military but also the civilian antiterrorism agencies, for example, the Homeland Security. Toward developing a respiratory medical countermeasure for SM, four different classes of therapeutic compounds have been evaluated in the past: anti-inflammatory compounds, antioxidants, protease inhibitors and antiapoptotic compounds. This review examines all of these different options; however, it suggests that preventing cell death by inhibiting apoptosis seems to be a compelling strategy but possibly dependent on adjunct therapies using the other drugs, that is, anti-inflammatory, antioxidant, and protease inhibitor compounds.

Abstract Background: This study was conducted to evaluate the anti-inflammatory effect of atorvastatin in patients with chronic bronchitis due to sulfur mustard gas inhalation. Methods: In this randomized double-blinded clinical trial we enrolled patients with chronic bronchitis due to sulfur mustard gas inhalation. Ninety man aged between 45 to 75 years with diagnosed of chronic bronchitis due to exposure to mustard gas during the Iran-Iraq war, were randomly assigned to receive either atorvastatin (40 mg) or placebo, given orally once a day for 3 months. The interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), procalcitonin, highly sensitive CRP, and COPD assessment test (CAT) score in both groups compared with each other and baseline data. Results: After 12 weeks of using atorvastatin (n=40), the level IL-6 decreased significantly (p=0.03) without any significant differences in the level of TNF-α, high sensitive CRP, and procalcitonin (P=0.31, p=0.78, and p=0.08). In placebo group (n=38), both procalcitonin and IL-6 significantly decreased after 12 weeks (P=0.002 and p<0.001), but levels of high sensitive CRP did not differ significantly and the level of TNF-α increased (p=0.006). The mean differences in levels of TNF- α, IL-6, high sensitive CRP, and procalcitonin did not differ statistically significant between the study groups after 12 weeks. Although after 12 weeks of study in both groups the CAT score have had appreciably high magnitude decrease (P<0.001), but its mean differences change wasn't significant between group (P=0.71). Conclusions: Administration of 40 mg atorvastatin for 3 months although could not significantly change systemic inflammatory markers or quality of life in mustard gas induced chronic bronchitis.Trial registration: IRCT, IRCT138904144312N1.

ABSTRACT Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that emerged as a health problem worldwide. It seems that COVID-19 is more lethal for Iranian veterans with a history of exposure to mustard gas. There are some similarities in the pathogenesis of SARS-CoV-2 and mustard gas in immune system disruption and pulmonary infection. SARS-CoV-2 and mustard gas inducing oxidative stress, immune system dysregulation, cytokine storm, and overexpression of angiotensin-converting enzyme II (ACE2) receptor in lungs that act as functional entry receptors for SARS-CoV-2. Moreover, Iranian survivors of mustard gas exposure are more susceptible and vulnerable to COVID-19. It is suggested that the principles of COVID-19 infection prevention and control be adhered to more stringently in Iranian survivors of mustard gas exposure than others who have not been exposed to mustard gas. Therefore, in this review, we discuss the different pathologic aspects of lung injury caused by mustard gas and also the relationship between this damage and the increased susceptibility of Iranian mustard gas exposed survivors to COVID-19.

We demonstrate a microporous metal–organic framework NU-400 based on a 2,7-disubstituted pyrene linker as a highly efficient photosensitizer for generating singlet oxygen and subsequent oxidative degradation of chemical warfare agents (CWAs). The high activity of NU-400 permits photocatalytic conversion of the 2-chloroethyl ethyl sulfide (CEES) mustard gas simulant into a benign sulfoxide derivative, in air, with less than 15 minutes’ half-life. This is a considerable improvement to NU-1000, based on a 1,3,6,8-tetrasubstituted pyrene unit, demonstrating how variation of the substitution pattern of a metal–organic framework linker permits modification of its photoactive behavior.
