Background Iran was one of the first countries to be affected by COVID-19. Identifying factors associated with the severity of COVID-19 is effective in disease management. This study investigated the epidemiological and clinical features and factors related to the severity of COVID-19 in one of the less privileged areas in Iran. Methods In a multi-center study, all patients admitted to Zahedan University of Medical Sciences hospitals in southeastern Iran were investigated from February 29 to April 31, 2020. Demographic, epidemiological, and clinical data of patients were extracted from medical records. Bivariate and multivariate logistic regression models were used to explore the risk factors associated with the severity of COVID-19. Results Among the 413 patients, 55.5% were male, and 145 (35.10%) were in a severe condition at admission time. Multivariate analysis showed that the adjusted odds of the disease severity increased in patients with older age (OR 2.27; 95% CI 1.41–3.65), substance abuse (OR 2.49; 95% CI 1.14–5.43), having one underlying disease (OR 1.52; 95% CI 0.90–2.55), having two underlying disease (OR 2.31; 95% CI 1.19–4.50), and having three or more underlying disease (OR 2.60; 95% CI 1.19–5.66). Conclusions COVID-19 was more severe in older patients, patients with a history of substance abuse, and patients with the underlying disease. Understanding the factors affecting the disease severity can help the clinical management of COVID-19, especially in less privileged areas where fewer resources are available.

Background and Objectives:In this study, we investigated the T helper (Th) to T cytotoxic (Tc) ratio in children suffered from hemophilia disease. 80 diagnostic subjects referred to Ali Asghar hospital of Zahedan city, Zahedan-Iran, were selected and the ratio of these cells were analyzed by analytic descriptive methods.Method of study:Two mls of EDTA anti coagulated whole blood was collected. Immunophenotyping of lymphocytes count was carried out by FACS analysis using a double CD4 and CD8 kit. The mean ± SD of absolute numbers of CD4 and CD8 lymphocytes/ml was calculated and the ratio of CD4/CD8 was evaluated by statistical method.Results:We found 100% of patients were type A hemophilia. Among of them 66 (82.5%) were male. The mean age was 15±3.51 years. 12 (15%) of them had mild disease intensity and 68 (85%) had sever disease intensity. The ratio of CD4 and CD8 was obtained between 0.45 and 1.44 with mean1.79 ±0.78 and correlation with the gender and disease intesivity was 0.095 and 0.019 respectively.Conclusions:The results showed that the ratio of T helper (Th) to T cytotoxic (Tc) has significant correlation with

Background: Beta-thalassemia major (TM) is one of the most common genetic diseases in Iran. Despite some efforts to reduce the incidence of TM, its incidence is still relatively high in some areas of the country. Methods: This cross-sectional study was performed on 635 families who had children with TM. The families that had more than one child with TM were enrolled. A demographic data questionnaire and a checklist containing queries about the reasons for the birth of the second or subsequent TM children were completed by each family. Finally, the data were analyzed using SPSS version 16. Results: Among the families that had more than one child with TM, 90, 23, and three families had two, three, and four children with the disease, respectively. Of the 261 patients studied, 125 (47.9%) and 136 (52.1%) had been born prior and after the implementation of the pre-marital screening program for beta-thalassemia in Iran, respectively. Also, in 29.4% of these families, parents were unaware of having thalassemia minor. In other cases, factors such as lack of knowledge about screening tests (14.0%), lack of financial compliance (13.2%), late referral for genetic tests (11.8%), and not undergoing screening tests despite recommendations (9.6%) were among the reasons declared by the families. In addition to these, religious and cultural reasons should also be mentioned as effective factors. Conclusions: This study showed that in only about 30% of the studied families, the parents were unaware of having thalassemia minor, and in other families, miscellaneous reasons were involved in the birth of the second or subsequent child with TM. In some cases, despite sufficient parental knowledge about the possibility of giving birth to a child with TM, no action was taken to prevent this event.
