Abstract

Background: Numerous studies on the effectiveness of vitamin C against the COVID-19 infection have been widely carried out recently. However, the differences in dosage ranges and therapeutic efficacy in previous studies have prompted a systematic literature review on the effectiveness of vitamin C on outcomes in COVID-19 patients. In addition, this study aimed to determine the appropriate therapeutic dose of vitamin C for COVID-19 patients, either alone or in combination with other supplements, and to determine the side effects.Methods: Gleaned from the search on Pubmed, Science Direct, and Google Scholar databases up to April 25, 2022, fourteen studies were relevant, namely five studies using vitamin C orally and nine studies administered intravenously. We assessed multiple outcomes, including mortality, hospitalization, and symptoms. The quality and risk of bias analyses were performed using JBI critical appraisal tools.Results: The oral administration of vitamin C resulted in a significant difference in the mortality of COVID-19 patients (OR=0.66; 95% CI=0.45–0.97; P=0.04; I2=0%) and a non-significant difference in the outcome. Duration of hospitalization (OR = -0.21; 95% CI = -2.70-2.28; P=0.87; I2=94%). Regarding the cost-effectiveness and side effects manifested in digestive disorders such as nausea, diarrhea, stomach cramps, and vomiting, vitamin C with a dose of 500-1000 mg could be given orally.Conclusion: Oral administration of vitamin C showed a reduction in the mortality of asymptomatic COVID-19 patients with moderate symptoms.

Abstract

Thalassemia β major is a hereditary disorder caused by mutations in the β-globin gene, which regulates the formation of one of the components that make up hemoglobin. This disorder results in the production of β-globin chains being reduced or not formed. The prevalence of thalassemia carriers in Indonesia reached 3.8% of the entire population based on data from the Ministry of Health in 2019. Therapy for thalassemia β major patients is lifelong transfusion, which results in iron overload and triggers hypocalcemia and osteoporosis. The aim of this study was to determine the relationship between ferritin levels and calcium levels in thalassemia β major patients. This study uses an observational analytic research type and a cross-sectional research design. This research was conducted at the RSD dr. Soebandi Jember, Jember Clinic Plantation Hospital, and in December 2019-January 2020. The total sample was 13 patients suffering from thalassemia β major aged 1-18 years. The results of the Pearson analysis showed that p=0.858 showed that there was no ignificant correlation between ferritin levels and calcium levels in Thalassemia β major in Jember. Keywords: Thalassemia β major, ferritin levels, calcium levels, hypocalcemia
