Background Levamisole has shown clinical benefits in the management of COVID-19 via its immunomodulatory effect. However, the exact role of Levamisole effect in clinical status of COVID-19 patients is unknown. We aimed to evaluate the efficacy of Levamisole on clinical status of patients with COVID-19 during their course of the disease. Methods This prospective, double-blind, randomized controlled clinical trial was performed in adult patients with mild to moderate COVID-19 (room-air oxygen saturation > 94%) from late April 2020 to mid-August 2020. Patients were randomly assigned to receive a 3-day course of Levamisole or placebo in combination with routine standard of care. Results With 25 patients in each arm, 50 patients with COVID-19 were enrolled in the study. Most of the study participants were men (60%). On days 3 and 14, patients in Levamisole group had significantly better cough status distribution when compared to the placebo group (P-value = 0.034 and 0.005, respectively). Moreover, there was significant differences between the two groups in dyspnea at follow-up intervals of 7 (P-value = 0.015) and 14 (P-value = 0.010) days after receiving the interventions. However, no significant difference in fever status was observed on days 1, 3, 7, and 14 in both groups (P-value > 0.05). Conclusion The results of the current study suggest that Levamisole may improve most of clinical status of patients with COVID-19. The patients receiving Levamisole had significantly better chance of clinical status including cough and dyspnea on day 14 when compared to the placebo. However, the effect-size of this finding has uncertain clinical importance. Trial registration The trial was registered as IRCT20190810044500N7 (19/09/2020).
Colchicine has shown clinical benefits in the management of COVID‐19 via its anti‐inflammatory effect. However, the exact role of colchicine in COVID‐19 patients is unknown. The current clinical trial was performed on 202 patients with moderate to severe COVID‐19. Patients were randomly assigned in a 1:1 ratio to receive up to a 3‐day course of 0.5 mg colchicine followed by a 12‐day course of 1 mg colchicine in combination with standard care or a 15‐day course of standard care. Among 202 randomized patients, 153 completed the study and received colchicine/standard care or continued standard care (M age, 54.72 [SD, 15.03] years; 93 [63.1%] men). On day 14, patients in the colchicine/standard care group had significantly higher odds of a better clinical status distribution on chest CT evaluation (p = .048). Based on NYHA classification, the percentage change of dyspnea on day 14 between groups was statistically significant (p = .026), indicating a mean of 31.94% change in the intervention group when compared with 19.95% in the control group. According to this study, colchicine can improve clinical outcomes and reduce pulmonary infiltration in COVID‐19 patients if contraindications and precautions are considered and it is prescribed at the right time and in appropriate cases.
Objectives Basic and clinical studies have shown that magnesium sulphate ameliorates lung injury and controls asthma attacks by anti-inflammatory and bronchodilatory effects. Both intravenous and inhaled magnesium sulphate have a clinical impact on acute severe asthma by inhibition of airway smooth muscle contraction. Besides, magnesium sulphate can dilate constricted pulmonary arteries and reduce pulmonary artery resistance. However, it may affect systemic arteries when administered intravenously. A large number of patients with covid-19 admitted to the hospital suffer from pulmonary involvement. COVID-19 can cause hypoxia due to the involvement of the respiratory airways and parenchyma along with circulatory impairment, which induce ventilation-perfusion mismatch. This condition may result in hypoxemia and low arterial blood oxygen pressure and saturation presented with some degree of dyspnoea and shortness of breath. Inhaled magnesium sulphate as a smooth muscle relaxant (natural calcium antagonist) can cause both bronchodilator and consequently vasodilator effects (via a direct effect on alveolar arterioles in well-ventilated areas) in the respiratory tract. We aim to investigate if inhaled magnesium sulphate as adjuvant therapy to standard treatment can reduce ventilation-perfusion mismatch in the respiratory tract and subsequently improve arterial oxygen saturation in hospitalized patients with COVID-19. Trial design A multi-centre, open-label, randomised controlled trial (RCT) with two parallel arms design (1:1 ratio) Participants Patients aged 18-80 years hospitalized at Masih Daneshvari Hospital and Shahid Dr. Labbafinejad hospital in Tehran and Shahid Sadoughi Hospital in Yazd will be included if they meet the inclusion criteria of the study. Inclusion criteria are defined as 1. Confirmed diagnosis of SARS-CoV-2 infection based on polymerase chain reaction (PCR) of nasopharyngeal secretions or clinical manifestations along with chest computed tomography (chest CT) scan 2. Presenting with moderate or severe COVID-19 lung involvement confirmed with chest CT scan and arterial oxygen saturation below 93% 3. Length of hospital stay ≤48 hours. Patients with underlying cardiovascular diseases including congestive heart failure, bradyarrhythmia, heart block, the myocardial injury will be excluded from the study. Intervention and comparator Participants will be randomly divided into two arms. Patients in the intervention arm will be given both standard treatment for COVID-19 (according to the national guideline) and magnesium sulphate (5 cc of a 20% injectable vial or 2 cc of a 50% injectable vial will be diluted by 50 cc distilled water and nebulized via a mask) every eight hours for five days. Patients in the control (comparator) arm will only receive standard treatment for COVID-19. Main outcomes Improvement of respiratory function and symptoms including arterial blood oxygen saturation, dyspnoea (according to NYHA functional classification), and cough within the first five days of randomization. Randomisation Block randomisation will be used to allocate eligible patients to the study arms (in a 1:1 ratio). Computer software will be applied to randomly select the blocks. Blinding (masking) The study is an open-label RCT without blinding.

Background: One of the complications of critical ill patients admitted to intensive care unit (ICU) are stress-related mucosal damage. Stress ulcer prophylaxis (SUP) should be administered to all critically ill patients with at least one major risk factor and two or more minor criteria. Methods: This study was performed during 6 months from October 2013 to December 2013 in Namazi Hospital intensive care units to assess the appropriate administration of SUP, according to American Society of Health-System Pharmacists (ASHP) protocol. Candidate for SUP according the ASHP guideline is considered if there is a at least one major risk factor or two or more minor risk factors. Results: Ninety-four patients were enrolled (46 men and 48 women). The mean age of study subjects was 51.5 years. The most major risk factor to stress ulcer found to be mechanical ventilation more than 48 hours (53%). The most minor risk factor for stress ulcer was ICU admission for less than one week (23.5%). Most prescribed medication for stress ulcer prophylaxis was intravenous Pantoprazole (44.7%). Our results have shown that about 74% patients were candidate for SUP according the ASHP guideline. 13(13.8%) of patients had only major risk factors. 5 (5.3%) of patients received SUP while they did not have at least one major risk factor or two or more minor risk factors. Conclusion: Our results have shown that 76.2% of the total SUP administrations were compliant with the ASHP guideline. Among the prescribed medication for SUP, intravenous pantoprazole had the highest percentage of administration (44.7%) and oral omeprazole had the lowest percentage of administration (7.4%). According to the results of our study, 72% of the route administrations are compliant with the ASHP guideline.
Chronic conditions are a major global concern. Chronic rheumatic diseases, diabetes mellitus, hypertension, depression, psychosis, inflammatory bowel diseases, multiple sclerosis, coronary vascular disease, dyslipidemia and also chronic rheumatic disorders are among the most common chronic conditions requiring chronic drug therapy. Looking for an optimum strategy in managing patients with chronic disorders is very important. Patient convenience, drug safety, and maximum efficacy form the rationale for finding the best treatment in caring for patients with chronic disorders. Throughout the history of rheumatology, great achievements have been made in improving the management of chronic rheumatic disorders using more specific drugs, especially targeted agents and signaling inhibitors, to overcome disabling diseases more precisely. Apart from non-pharmacological management of rheumatic disorders, drug therapy is the cornerstone for treatment in most instances. Therefore, the safety profile of management is crucial. Strategies for reducing adverse drug reactions and maximizing the benefits and compliance with drug therapy should be our major concerns. Most researchers and pharmaceutical companies endeavor to develop new drugs with more specific measures based on the pathophysiology of the disease. However, clinical rheumatologists should consistently search for the optimum management strategy with the available medications. Ongoing modifications to ideas and understanding previous pitfalls make medicine an everchanging science and practice. However, considering the over-emphasis on new medicine and occasional gap between clinical practice and pharmacy disciplines to improve treatment guidelines may impose some burdens for patients in cases of classic medications. For a long period of time, systemic corticosteroids were the standard EditorialOpen Access
Background. Myopathy is one of the side effects of lipid-lowering drugs, especially statins and particularly when combined with a fibrate. To diagnose myopathy and determine its severity, the plasma levels of three enzymes, creatine kinase (CK), aldolase, and lactate dehydrogenase (LDH), are routinely measured. Physical exercise can aggravate the statin-associated muscular disease. The question is whether antioxidants like ascorbic acid (Vit. C) can prevent such myopathy. Methods. In this experiment, a combination of atorvastatin (ATV, 80 mg/kg/day) and gemfibrozil (GMF, 1000 mg/kg/day) orally for 10 days as well as exercise as forced swimming on days 8, 9, and 10 were used to induce myopathy. Ascorbic acid (50 mg/kg/day, orally) was added to ATV/GMF plus exercise regimen throughout the 10 days in the treatment group. Mean blood levels of CK, aldolase, and LDH were measured in addition to swimming tolerance times. Results. There was a significantly higher swimming tolerance time P < 0.05 and lower CK levels P < 0.01 in rats receiving ATV/GMF/Vit. C plus exercise compared with rats not taking Vit. C. LDH and aldolase did not decrease significantly. Conclusion. The results of this study showed that Vit. C can be effective in preventing myopathy caused by fat-lowering drugs.
