DR is the leading cause of preventable blindness in T2DM. Retinal ischemia, detectable by fluorescein angiography (FA), is an early indicator, and its timely detection is crucial. Endothelial dysfunction affects vessels in organs such as the retina and kidneys. Microalbuminuria (MA) is an early sign of diabetic nephropathy (DN). Early detection, along with adequate metabolic control, can delay progression to end-stage renal disease.Objective: To investigate the relationship between retinal ischemia, detected by FA, and MA in patients with T2DM and non-proliferative DR at the No. 1 Specialty Hospital of Bajío.Material and methods: Cross-sectional study, with ethical approval. Diabetic patients without previous renal disease or proliferative DR were included. The sample of 66 patients was evaluated by FA and MA analysis (>30 mg/24 h). Chi-square and Student's t-tests were applied.Results: Patients with retinal ischemia were older (62.73 ± 8.93 vs. 57.50 ± 14.14 years; p = 0.05) and had a higher prevalence of MA (45% vs. 0%; p = 0.01). No significant differences were found in gender, DR severity, HbA1c, or creatinine levels.Conclusions: Retinal ischemia is associated with a higher prevalence of microalbuminuria in T2DM patients, supporting the study hypothesis.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"63 2","pages":"e6434"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12043348/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144040330","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}

Interferon plays important roles in restricting viruses and is crucial because it participates in both innate and adaptive immunity. Gamma interferon (IFN-γ) is a cytokine that plays a fundamental role in maintaining homeostasis in the body, both in vitro and in vivo.Objective: An immunological study was conducted to measure the concentrations of IFN-γ in severe SARS-CoV-2-positive patients.Material and methods: Around 500 sera from patients with similar respiratory comorbidities at the onset of the disease were analyzed, using healthy patients as controls. The sera from SARS-CoV-2-positive individuals were processed using the ELISA technique, and the statistical treatment of the data involved creating a database with the absorbance readings, which were then converted into concentrations in pg/ml.Results: We can infer that the amount of IFN-γ expression depends on the patient's condition; the more severe the patient's condition, the higher the expression of this cytokine compared to their baseline levels, ranging from 0 to 0.5 μg/ml.Conclusion: It is suggested that the IFN-γ response plays an important role in controlling the disease, and effective therapies are recommended for the treatment of Covid-19, which will lead to the implementation of therapeutic approaches aimed at counteracting the immune system, especially in the more severe forms of the disease.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"63 2","pages":"e6353"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12165371/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015546","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}
