Background. The outbreak of COVID-19 - COronaVIrus Disease 2019 - has become a significant threat to public health worldwide, with high contagious capacity and varied mortality in different countries. Diabetes mellitus (DM/ diabetes) is among the most frequently reported comorbidities in patients with COVID-19. In the field of physical and rehabilitation medicine and balneotherapy, specific rehabilitation procedures, natural therapeutic factors, and physical activity are known to be contributive to mitigating some of the DM clinical-patho-biological consequences. Objective. This systematic review aims to rigorously select related articles and identify within their content, the main possible interferences between DM and COVID-19’s pathological mechanisms, and to discuss the value of physical and rehabilitation medicine and balneotherapy in the post-acute COVID-19 recovery of the surviving patients. Methods. This systematic review, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, searched for open-access articles published in English, between January and May 2020, from the following databases: Cochrane, Elsevier, PubMed and Web of Science. The contextually searched syntax used was ”DIABETES AND COVID-19”. The selected articles were analyzed in detail regarding both pathologies: COVID-19 and DM. The meta-analysis proceeded was designated to estimate the prevalence of DM among COVID-19 patients. Results. Our search has been conducted on five stages, described by a PRISMA adapted flow diagram. Within the first stage, using the syntax mentioned above resulted in 1,133 articles. After eliminating, in the second stage, all the inevitable redundancies remained 1,058 articles. In the third stage, we performed a PEDro qualitative analysis score weighted selection of all the papers and were kept 91 articles. In the fourth stage, were selected relevant issues for a meta-analysis regarding the prevalence of DM diabetes among COVID-19 cases, resulting 32 papers. The fifth stage of the PRISMA adapted flow diagram was dedicated to the analysis of the data regarding the use of natural therapeutic factors, physical exercises within the ensemble of case-specific indicated procedures used for DM, and COVID-19 patients in rehabilitation wards. For enhancing the bibliographical sources pool, we added from external, free found sources, another 15 articles. Discussion/ Limitation. COVID-19 is an acute illness condition and DM is a chronic one. Therefore, it is difficult for now, to have enough data enabling us to see all the repercussions of COVID-19 and to completely understand the significance of physical and rehabilitation medicine and balneotherapy, which applies in COVID-19 post-acute DM patients. Conclusions. This paper overviews the current state-of-the-art knowledge in the approach of DM /diabetes as COVID-19 comorbidity, with a focal point on the roles of natural therapeutic factors, physical exercises within the ensemble of case-specific indicated procedures used for DM and COVID-19 patients in rehabilitation wards, for possible actual and future connexions with the comprehensive management/ rehabilitation of such both chronic and post-acute survivors.
