This retrospective study encompassed all adult patients with laboratory-confirmed COVID-19 and pre-existing CKD admitted between May 2020 and May 2023. Their demographic data, relevant clinical parameters, and laboratory values were collected. Kaplan-Meier curve analysis and Log Rank test were employed to compare survival times between CKD patients and those developing acute kidney injury (AKI), while Cox regression analyses were conducted to pinpoint factors influencing the hazard of a fatal outcome. The study, involving 150 COVID-19 patient records with pre-existing CKD, revealed that male gender, advanced age, requirement for invasive ventilation, and elevated levels of inflammatory markers such as total leukocyte count, lactate dehydrogenase, C-reactive protein, D-dimer, and IL-6 significantly increased the risk of death.

Having a concrete idea of the effects of therapeutic interventions on the size and metabolism of the PRAT could prove highly beneficial. This review summarizes what is known about the PRAT and provides a collection of studies on the effects of therapeutic interventions on PRAT and its related diseases. We used papers written on a variety of subjects, mainly concerning adipose tissue and the effects of therapeutic procedures on it. Our main challenge was to excerpt the information specifically related to the PRAT in these papers. These effects vary greatly, from an increase or decrease in mass or size of the PRAT to changes in metabolism and drug residue accumulation. The current studies often fail to consider PRAT as an individual subject of research and only examine the adipose tissue of the entire body as a whole. This leads us to believe this field could benefit greatly from further research.</p>","PeriodicalId":13359,"journal":{"name":"Indian Journal of Nephrology","volume":"34 6","pages":"573-582"},"PeriodicalIF":0.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11619052/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142794690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
