ABSTRACT
Background and purpose: COVID-19 is a viral respiratory disease that results in high mortality. Evidence suggests that micronutrients affect viral and bacterial infections. This study was performed to evaluate the effectiveness of micronutrients (vitamin D, vitamin C, and selenium) on the disease severity in patients hospitalized with COVID-19. Materials and methods: This retrospective cross-sectional study was carried out in patients with diagnosis of COVID-19 in Qaemshahr Razi Hospital, 2020. Medical records were reviewed and 42 were selected. Data of patients that received micronutrients including vitamin D, vitamin C, and selenium and those that did not receive these supplements were compared. Duration of hospitalization, respiratory support, oxygen therapy, requiring invasive/non-invasive mechanical ventilation, and incident of death were investigated. Statistical analysis was done in SPSS V25.
ABSTRACT
Background and purpose: COVID-19 is a viral respiratory disease that results in high mortality. Evidence suggests that micronutrients affect viral and bacterial infections. This study was performed to evaluate the effectiveness of micronutrients (vitamin D, vitamin C, and selenium) on the disease severity in patients hospitalized with COVID-19. Material(s) and Method(s): This retrospective cross-sectional study was carried out in patients with diagnosis of COVID-19 in Qaemshahr Razi Hospital, 2020. Medical records were reviewed and 42 were selected. Data of patients that received micronutrients including vitamin D, vitamin C, and selenium and those that did not receive these supplements were compared. Duration of hospitalization, respiratory support, oxygen therapy, requiring invasive/non-invasive mechanical ventilation, and incident of death were investigated. Statistical analysis was done in SPSS V25. Result(s): Survival rates in the groups receiving vitamin C, D, and selenium were not significantly different from the groups that did not receive these supplements (P= 0.42, 0.63, 0.084, respectively). The study showed no significant relationship between vitamin D, C, and selenium intake and the need for ventilation due to respiratory distress (P= 0.139, 0.2, and 0.8, respectively). Conclusion(s): No remarkable difference was seen between the recipients of vitamin C, D, and selenium and those who did not receive supplements in terms of survival and the need for mechanical ventilation. So, these supplements did not affect the clinical outcomes of patients with COVID-19. Copyright © 2022, Mazandaran University of Medical Sciences. All rights reserved.
ABSTRACT
Background: Lymphopenia is an important but nonspecific laboratory indicator of COVID-19. Objectives: To describe epidemiologic and clinical characteristics of the first cases of the COVID-19 referred to a center dedicated to COVID-19 patients in Iran. Methods: This research is a retrospective cross-sectional study on 100 confirmed cases with COVID-19, hospitalized from February 25 to March 10, 2020, in Qaemshahr Razi Hospital in Mazandaran Province, Iran. The main demographic data, clinical features, including outcomes, laboratory findings, and therapeutic protocols, were collected in a structured form and analyzed. Results: The Mean±SD age of the patients was 56.7±15.6 years. Fifty-nine percent (n=59) of the patients were male. Nineteen percent (n=19) were admitted to the ICU. The median (IQR) time from disease onset to hospital admission was 5 (3-7) days. The most common symptoms were fever (73%), dyspnea (67%), dry cough (61%), and myalgia (61%). The severity of the disease was moderate in most patients (n=54). The average hospital stay for patients was 7 days. The non-survivor cases in comparison to survived ones were from a higher age group (65 vs 52 years;P=0.001), had a higher frequency of underlying diseases (68.4% vs 39.5%;P=0.039), had a lower peripheral capillary O2 saturation at the time of admission (79% vs 94%;P<0.001), and were more likely to have lymphopenia (63.2% vs 37%;P=0.034). Conclusion: Lymphopenia, increased neutrophil to lymphocyte ratio and decreased peripheral capillary O2 saturation are commonly seen in COVID-19 patients, especially among severe cases, and can be used in developing clinical prediction rules.
