Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) whose pandemic was declared on March 11 2021 (1). Spectrum of COVID-19 clinical manifestations is very wide. Most patients report to ambulance with mild or moderate symptoms, but some of them rapidly develops acute respiratory distress syndrome (ARDS), respiratory failure, acute cardiac injury, multiple organ failure and death (2). Older age, diabetes mellitus and cardiovascular disease are reported as high predictors of morbidity and mortality. Aim: To determine correlation between diabetes mellitus and severity of clinical picture in patients with COVID-19. Methods: Current study involve retrospective analysis of 1513 patients with Real Time PCR confirmed COVID-19 hospitalized in Clinic for infectious disease, University Clinical Center, Sarajevo, Bosnia and Herzegovina, in a period of June 2020 to December 2020. Results: Among them 417 had previously diagnosed of diabetes mellitus. Results show that patients with diabetes mellitus are likely to require treatment in Intensive care unit, and oxygenic support with invasive ventilation. There was no statistically significant difference in outcome of the disease. Conclusion: Even this study didn’t find increased mortality in patients with COVID-19 and diabetes mellitus, further studies should be done to determine risk for patients with DM to develop severe form of disease.                   Peer Review History: Received 23 March 2021; Revised 17 April; Accepted  5 May, Available online 15 May 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.  Received file:      Reviewer's Comments: Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10 Reviewer(s) detail: Dr. Branislav Rankovic, University of Kragujevac, Serbia, rankovic@kg.ac.rs Dr. Poualeu  Kamani  Sylviane  Laure, University of Dschang, Cameroon, poualeusylviane@yahoo.fr Similar Articles: THE RISKS AND ADVANTAGES OF ANTI-DIABETES THERAPY IN THE POSITIVE COVID-19 PATIENT

Abstract Introduction. Present study was performed to verify red blood cell distribution width-to-platelet ratio (RPR) level in rheumatoid arthritis (RA) patients and to examine its correlation with clinical and biochemical indicators of disease activity status. Methods. In this cross-sectional analytical study, 67 patients with RA and 34 age- and gender-matched healthy control subjects were enrolled. Based on the disease activity score 28-ESR (DAS28-ESR), RA patients were divided into subgroups: low disease activity (n = 20), moderate disease activity (n = 22) and high disease activity (n = 25). Laboratory tests included erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, platelet count (PLT), red blood cells count (RBC), red blood cells distribution width (RDW) and fibrinogen concentration. Statistical analyses were carried out using SPSS 13 software. Statistical significance was set at a p-value less than 0.05. Results. There was statistically significant difference (p = 0.006) between RPR in RA patients with different stages of disease activity, with higher values in patients with low disease activity. The RPR showed statistically significant negative correlations with ESR (rho = –0.309; p = 0.012), CRP (rho = –0.421; p = 0.001), swollen joint count – SJC (rho = –0.368; p = 0.002) and tender joint count – TJC (rho = –0.355; p = 0.003), DAS28-ESR (rho = –0.409; p = 0.001), DAS28-CRP (rho = –0.422; p < 0.0005) and Visual analogue scale – VAS (rho = –0.260; p = 0.033) in RA patients. Conclusion. The present study provided evidence that the lower RPR values in RA patients are significantly associated with the disease activity indicators.
