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

Aim To describe characteristics and outcome of mechanically ventilated patients admitted to three newly established intensive care units (ICU) in Bosnia-Herzegovina and Serbia for 2009 H1N1 influenza infection. Methods The retrospective observational study included all mechanically ventilated adult patients of three university-affiliated hospitals between November 1, 2009 and March 1 2010 who had 2009 H1N1 influenza infection confirmed by real-time reverse transcriptase-polymerase-chain-reaction (RT-PCR) from nasopharyngeal swab specimens and respiratory secretions. Results The study included 50 patients, 31 male (62%), aged 43 ± 13 years. Median time from hospital to ICU admission was 1 day (range 1-2). Sixteen patients (30%) presented with one or more chronic medical condition: 8 (16%) with chronic lung disease, 5 (10%) with chronic heart failure, and 3 (6%) with diabetes mellitus. Thirty-two (64%) were obese. Forty-eight patients (96%) experienced acute respiratory distress syndrome (ARDS), 28 (56%) septic shock, and 27 (54%) multiorgan failure. Forty-five patients (90%) were intubated and mechanically ventilated, 5 received non-invasive mechanical ventilation, 7 (14%) high-frequency oscillatory ventilation, and 7 (14%) renal replacement therapy. The median duration of mechanical ventilation was 7 (4-14) days. Hospital mortality was 52%.
