PurposeStatins are known as cholesterol-lowering agents, but have been suggested for the treatment of asthma because of their anti-inflammatory effects. In this study, the potential therapeutic effects of atorvastatin were investigated in asthmatic patients.MethodsA total of 62 patients with persistent mild to moderate asthma who presented at asthma clinics of Arak University of Medical Sciences were recruited in a double-blind randomized clinical trial. The asthma clinical control score was assessed based on the standardized Asthma Control Test. Lung volume, i.e., percentage of forced expiratory volume in one second (FEV1%) and percentage of forced vital capacity (FVC%), and peripheral blood eosinophils were also measured. The intervention group was treated with atorvastatin 40 mg per day for 8 weeks, while the control group received a placebo. Asthma controller treatments were not changed. At the beginning and end of the study, serum cholesterol and triglyceride levels were measured to evaluate adherence of the patients to the treatment.ResultsThe asthma control score did not significantly differ between the intervention and control groups (P=0.06). Difference in FEV1%, FVC%, and blood eosinophil count between the intervention and control groups were not statistically significant (P>0.05). The differences in post-treatment cholesterol and low-density lipoprotein cholesterol levels were significant (P<0.05).ConclusionsOur study shows that atorvastatin is not effective in the treatment of persistent mild to moderate asthma.

Ocular involvements in a number of patients progress toward a severe, rapid onset form of keratitis. Progressive deterioration of respiratory tract leads to "mustard lung". Skin problems continue as chronic frustrating pruritus on old scars with susceptibility to skin cancers. Due to the multiple acute and chronic morbidities created by SM exposure, uses of multiple drugs by several routes of administrations are warranted.

The need of intubation and mechanical ventilation is associated with poor prognosis in COVID‐19 patients. Herein, we present two cases of patients with COVID‐19 where intubation and mechanical ventilation failed, and therefore, percutaneous dilatational tracheotomy was performed. The usage of PDT was associated with faster and better recovery in these patients.
