The effects of high dose vitamin D supplementation as a nutritional intervention strategy on biochemical and inflammatory factors in adults with COVID-19: Study protocol for a randomized controlled trial.

Introduction: Low serum vitamin D has been shown to be a risk factor for Coronavirus 2019 (COVID-19). The aim of this study was to assess the effects of high dose vitamin D supplementation on hs-CRP, ESR and clinical outcomes, including duration of hospitalization, quality of life and New York Heart Association (NYHA) Functional Classification, in adults with COVID-19. Methods: This double-blind, randomized control trial will be conducted on patients with RT-PCR and/or chest CT scan diagnosis of COVID-19 admitted in Imam Reza Hospital, Mashhad, Iran. Participants will be randomized into control and intervention groups based on randomization sampling. The intervention group will receive soft gel containing 50,000 IU vitamin D on the first day followed by 10,000 IU/day through a supplement drop daily for 29 days. The control group will receive 1000 IU vitamin D daily through supplement drop and a placebo soft gel. All participants will undergo laboratory assessment including inflammatory markers, serum 25)OH)D, complete blood count (CBC), liver and renal profile, lipid profile and erythrocyte sedimentation rate (ESR) at baseline and at day 30. The mortality rate will be recorded in both groups. Results: Data will be presented using descriptive statistics. Comparison of changes in study parameters over the study period will be performed using analysis of covariance adjusting for possible confounders. Conclusions: The findings of this will provide evidence on the effects of high dose vitamin D supplementation on inflammatory markers in hospitalized COVID-19 patients.

Case series: Rare cases of thyroid storm in COVID-19 patients.

Thyroid storm is an uncommon life-threatening thyroid dysfunction which was observed for the first time among patients infected with Coronavirus 2019 (COVID-19). The diagnosis and treatment of the rare thyroid distinctions such as thyroid storm in COVID-19-infected patients should be critically considered alongside common treatments of COVID-19 infection.

Covid-19 Presented Only with Gastrointestinal Symptoms: A Case Report of a 14-Year-Old Patient

Coronavirus disease 2019 (Covid-19) is expanding worldwide. Although it seems to be a purely respiratory disease, occasional reports of lesions in other organs have been published. We report here an asymptomatic child with Covid-19 and with the main symptom of abdominal pain distension and without any respiratory symptoms. A 14-year-old male patient with main complaints of fever, malaise, anorexia, and severe abdominal pain was admitted to a hospital in Mashhad, Iran. Laparotomy revealed distension of the small intestine and an adhesive ileocaecal band that had produced ileum herniation without free fluid in the abdomen. Chest radiography and high-resolution computed tomography of the lungs showed bilateral and diffuse, peripheral dense areas of ground-glass appearance. A nasopharyngeal swab for diagnosis of Covid-19, was ordered due to lymphopenia together with these diffuse lung infiltrations, which showed a positive result. This led to drug treatment with lopinavir/ ritonavir, hydroxychloroquine, ribavirin/oseltamivir, and meropenem. The patient was febrile and developed tachycardia on the third day, accompanied by a respiratory rate of 44/min. At this point, tracheal intubation was done, but the patient died after 3 hours due to cardiac arrest. The case report brings forth the hypothesis that the gastrointestinal manifestation may be an atypical symptom of Covid-19 infection and highlights the importance of the diagnosis based on combined laboratory-based data and scanning imagery.

An effective drug against COVID-19: reality or dream?

Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is well known as a novel member of the coronavirus family which caused a sudden outbreak of Coronavirus disease-2019 (COVID-19) in China that quickly developed into a global pandemic. No effective approaches are found as yet for the therapy and epidemiological control of this new virus. We searched the literature in PubMed, Scopus, Web of Knowledge, Google Scholar, and MeSH, for articles and abstracts describing SARS-CoV-2, COVID-19, pneumonia, clinical trials, drug, treatment, and medicine.Areas covered: The present study aimed to comprehensively overview the current literature on effective anti-SARS-CoV-2 drugs.Expert opinion: Since the beginning of this pandemic disease, many studies have been conducted to find effective drugs to prevent COVID-19, because there are no specific drugs for the treatment of this disease. Most of these drugs with the antiviral potential effect toward COVID-19 are already used as the treatment of other infectious diseases. Some drugs that show the promising therapeutic potential in the initial clinical studies include remdesivir as an inhibitor of RNA-dependent RNA polymerase and favipiravir as an inhibitor of virus replication. Currently, remdesivir received the FDA authorizes to use as an experimental drug for emergency use in COVID-19 patients.
