This pathological condition results in the formation of circulatory IgA immune complexes, which are essential for the development of glomerular inflammation, especially IgA nephropathy. The serum galactosylated IgA1, IgG, and IgA autoantibodies are suggested as the biomarkers of IgA nephropathy since IgA antibodies are early markers for disease activity too. Serum IgA antibodies emerged as the early COVID-19-specific antibody response about two days after initial symptoms of COVID-19 in comparison with IgG and IgM antibody concentrations, which appeared after five days. IgA nephropathy is frequently presented as microscopic or macroscopic hematuria and proteinuria with a male predominance. COVID-19 infection can include several organs aside from the lungs, such as kidneys through different mechanisms. It is demonstrated in most cases that short-lasting symptoms such as gross hematuria resolve either spontaneously or following a short course of steroids.

Considering the current COVID-19 pandemic, there is a need for studies investigating the various aspects of COVID-19 in patients with MHD. Objectives: The present study aimed to identify the risk factors associated with higher COVID-19- related mortality in patients under MHD. Patients and Methods: The present retrospective study included 90 patients under MHD who were hospitalized with COVID-19 and diagnosed using the reverse transcription polymerase chain reaction (RT-PCR) from March 20, 2020, to December 20, 2020. Results: The participants’ mean age was 57.5±18.61 years, and 49 patients (54.4%) were men. Moreover, 35 patients (38.9%) were expired due to COVID-19. The most common underlying diseases included diabetes mellitus, hypertension and cardiovascular diseases. The patients expired due to COVID-19 had a significantly higher chance of needing oxygen therapy, mechanical ventilation, and intensive care unit admission compared to survived patients. Moreover, a significant negative relationship between mineral-multivitamin supplementation and COVID-19-related mortality was detected. The prevalence of dyspnea was significantly higher in the expired patients compared to survived patients. Conclusion: The COVID-19 patients under MHD are high-risk for severe disease and mortality. Therefore, hemodialysis centers should establish strict preventive measures.","PeriodicalId":16515,"journal":{"name":"Journal of Nephropathology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43564215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The working hypothesis was that in patients on chronic hemodialysis the prevalence of left ventricular diastolic dysfunction is correlated with the inflammatory, oxidative, metabolic, nutritional, and atherosclerotic status. Patients and Methods: An observational study was performed on 51 patients (age 59.76 ± 13.24 years) on hemodialysis treatment. Transthoracic cardiac ultrasound was conducted to evaluate LVDD. The burden of cardiac and arterial atherosclerosis was evaluated by cardiac ultrasound (aortic and mitral valve calcifications), vascular ultrasound (carotid and femoral atheroma plaques, common carotid intima-media thickness), and by abdominal radiography (aortic calcification score). Demographic and anthropometric parameters were determined. Blood samples were used to determine laboratory parameters reflecting the inflammatory, oxidative, and metabolic/nutrition status. Results: LVDD is positively correlated with the serum level of C-reactive protein (CRP) (P=0.04), the total antioxidant capacity of the serum (P=0.04), the presence (P=0.022) and number (P=0.04) of femoral plaques, the aortic calcification score (P=0.02), aortic valve stenosis (P=0.037), aortic annulus calcifications (P=0.02) and mitral valve calcifications (P=0.041). After the removal of the main confounder, degenerative aortic stenosis, only the associations with serum total antioxidant capacity (P=0.04) and aortic calcification score (P= 0.02) maintain their statistical significance. Conclusion: LVDD is positively correlated with inflammation and oxidative stress markers and with the severity of aortic calcification.","PeriodicalId":16515,"journal":{"name":"Journal of Nephropathology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44256404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are little data on the relationship between renal dysfunction and COVID-19 prognosis. Objectives: The aim of this research was to investigate the effects of AKI in COVID-19 patients hospitalized to the Golestan and Razi hospitals in Ahvaz, Iran. Patients and Methods: In this retrospective cohort study, a total of 194 COVID-19 patients were included, consisting of 79 patients with AKI and 115 patients without AKI. Primary and secondary outcomes were compared between the two groups. Results: According to the findings, mortality was significantly different between the two groups, and mortality was higher in the AKI group (P< 0.001). The mean length of hospital stay was statistically significantly higher in the AKI group (P=0.024). Moreover, there was a significant correlation between intensive care unit (ICU) admission and the study group (P<0.001). Staging of AKI group were seen as; stage I (49.37%), stage II (36.71%), and stage III (13.92%). No significant correlation was observed between outcome and the stages of AKI (P=0.496). Furthermore, 14 patients (17.72%) needed renal replacement therapy (RRT) in the AKI group. Conclusion: Although AKI is a common finding in COVID-19 patients, most patients were in stage I disease, which returned to normal after COVID-19 treatment. According to our research, COVID-19 rarely leads to serious and persistent kidney injury. However, the risk of death is increased in COVID-19 patients with AKI. Therefore, it is necessary to evaluate the renal function tests during the course of disease.","PeriodicalId":16515,"journal":{"name":"Journal of Nephropathology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41419193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and Methods: We retrospectively reviewed hospital databases of all patients who underwent a percutaneous renal biopsy over an 18 years’ period at Santa Marta and Santa Venera hospital in Acireale. Results: The procedure led to a definitive diagnosis in the majority of cases (98.48%), being uninformative only in 5 out of 328 cases (1.52%). Comparing these results against a Proforma, resulting from analysis of best literature reports for the items studied, adverse event rates were similar. Conclusion: Freehand renal biopsy resulted a good option to obtain renal tissue, without serious side effects. We argue about safety and we prefer to reserve this invasive procedure to selected cases, avoiding renal biopsy if biochemical and instrumental data allow a definitive diagnosis as well as in high risk patients.
