Shafiee, M. Momenzadeh","doi":"10.34172/jnp.2023.18409","DOIUrl":"https://doi.org/10.34172/jnp.2023.18409","url":null,"abstract":"Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of coronavirus disease 2019 (COVID-19) which is associated with nonspecific respiratory syndromes, varying from mild symptoms of upper airway to required mechanical ventilation hypoxemia. A unique feature of this disease is COVID-19-associated coagulopathy (CAC) that linked with disease severity and hospital mortality. These patients have a profound hypercoagulable state and in patients with severe type arterial and venous thrombotic events are frequent. Abnormal coagulation parameters such as activated partial thromboplastin time (aPTT) were observed in patients with COVID-19. Regarding the above finding it could be considered as a reason to avoid anticoagulation at the both doses of therapeutic and prophylactic. A prolonged aPTT may indicate a coagulation factor deficiency or inhibitor of coagulation, which can be specific (antibody to factor VIII) or nonspecific (lupus anticoagulant, LA). LA can affect laboratory tests of blood coagulation, but is not usually associated with bleeding; however, it can be associated with thrombotic risk as a part of the antiphospholipid syndrome. In a phospholipid concentration-dependent manner LA recognizes a type of antiphospholipid antibodies (aPLs) that prolong clotting tests. In patients with antiphospholipid syndrome (APS) LA is considered as one of the laboratory criteria representing a significant risk factor of both thrombosis and pregnancy morbidity. Similarities between some of the pathophysiological features of COVID-19 and APS has been focused in several reports particularly in the most severe form, catastrophic APS. This study aimed to evaluate the effect of LA on the incidence of thrombophilia in patients with COVID-19, as well as its impact on the inflammation and finally the mortality final rate.","PeriodicalId":16515,"journal":{"name":"Journal of Nephropathology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48433171","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}

Reactivation or first onset of IgA vasculitis nephritis is uncommon; however, there have been increasing reports of this disease, as a complication of COVID-19 vaccination. It is possible that COVID-19 mRNA vaccination may trigger several auto-inflammatory and autoimmune cascades. Previous research has shown that Toll-like receptors play a role in the development of IgA vasculitis nephritis. Following injection of a COVID-19 mRNA vaccine, the uptake of double-stranded RNA by-products will trigger Toll-like receptors, leading to a series of intracellular cascades starting an innate immunity-driven process of cell-mediated and humoral- mediated immunity.","PeriodicalId":16515,"journal":{"name":"Journal of Nephropathology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49209371","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}

Pioglitazone is among the conventional antidiabetic drugs. The present study thus seeks to investigate the association between the administration of pioglitazone and the incidence of bladder cancer in type II diabetic patients through a meta-analysis and systematic analysis. Materials and Methods: International databases including Web of Science, Medline/PubMed, Scopus, and Google Scholar search engine were explored. To integrate the results of studies odds ratio (OR), risk ratio (RR) or hazard ratio (HR) logarithm was extracted from each study, and the I2 index or the Cochran’s Q test were conducted to examine the heterogeneities across studies. Data analysis was carried out in STATA version14 considering a significance level of p<0.05. Results: The 15 examined studies had investigated a total of 5,353,528 patients (1,536,723 patients in case groups and 3,816,805 patients in control groups). The relative risk of bladder cancer was [RR: 1.20 (95% CI: 1.09-1.32)] in pioglitazone users. Bladder cancer risk in pioglitazone users was higher by [RR: 1.14 (95% CI: 1.03-1.25)] compared to those who had never taken pioglitazone, [RR: 1.32 (95% CI: 1.02-1.70] compared to sulfonylurea users, and [RR: 1.57 (95% CI: 1.23-2)] compared to dipeptidyl peptidase-4 (DPP-4) users. Moreover, the relative risk between pioglitazone consumption and bladder cancer was reported to be [RR: 1.27 (95% CI: 0.96-1.68)] in patients with a follow-up shorter than five years and [RR: 1.24 (95% CI: 1.09-1.41)] is patients with a follow-up of five years or longer. On the other hand, the relative risk between pioglitazone consumption and bladder cancer was [RR: 1 (95% CI: 0.69-1.45)] in 50-59 age group, [RR: 1.20 (95% CI: 1.04-1.38)] in the 60-69 age group, and [RR: 1.33 (95% CI: 1.14-1.56)] in the 70-79 age group. Conclusion: Patients who receive pioglitazone had a 20% higher risk of bladder cancer compared to those who had not taken pioglitazone or prescribed other medication such as sulfonylurea and DPP-4s.

Knowledge of its epidemiology is crucial for its prevention and the optimal care. Objectives: The objective was to study the epidemiological characteristics of patients on chronic hemodialysis, their outcomes and explore their perceptions of therapeutic modalities, through a prospective cohort. Patients and Methods: A prospective study conducted between February 2019 and January 2020, at two public hemodialysis centers in Oujda, Morocco. Results: Around 183 patients were enrolled. The mean age was 53±17 years. The initial nephropathy was undetermined in 37% of cases and dominated by diabetes in 25.7%. About 43% of patients had pre-dialytic nephrology follow-up. Only 32% patients initiated their hemodialysis by an arterial-venous fistula (AVF). The mean hemoglobin rate was 10.3±1.8 g/dL. Moreover, 74 % of patients were under erythropoietin. Serum calcium, phosphorus, vitamin D, and parathormone were within target ranges in 67%, 52%, 61%, and 51% of cases, respectively. Since, 80% of patients were not clearly informed about therapeutic modalities. The majority of patients opted for kidney transplantation (KT), with two major constraints preventing its realization, consisting the lack of related living donors and financial resources. Besides, 29% of patients were hospitalized for cardiovascular and infectious causes during the study year. Death was observed in 7.1% of cases. Conclusion: Early detection of chronic kidney diseases in high-risk people, their rigorous follow-up and early referral to the nephrologist would improve the quality of care. The promotion of KT and PD would better meet the hemodialysis patients’ needs with better outcomes and lower costs.","PeriodicalId":16515,"journal":{"name":"Journal of Nephropathology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41917521","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: This study aimed to determine the possible gender-related differences in IgAN at a single center in Iran. Patients and Methods: All renal biopsy-proven cases of IgAN during the last 11 years (2009-2020) were studied. All kidney biopsies had two samples for immunofluorescence and light microscopy. Renal biopsies were reviewed using the recently revised Oxford classification of IgAN. In addition to Oxford-MEST morphologic variables, other data consisting of age, gender, serum creatinine and level of proteinuria within 24 hours at the time of biopsy were collected. The data were analyzed in SPSS version 21.0. Results: This study included 246 biopsy-proven cases of IgAN patients with a mean age of 38.23±13.71 years and a male prevalence of 67.1% (n=161). The mean ± SD values of serum creatinine and 24-hour proteinuria were 1.47±1.06 mg/dL and 1753.63±1049.418 mg/d, respectively. Analysis regarding age, serum creatinine, the quantity of 24-hour proteinuria, the number of sclerotic glomeruli, and the percent of interstitial fibrosis showed only serum creatinine to be significantly higher in males than females (P=0.017). Moreover, 24-hour proteinuria was higher in males than females (P=0.047). Our study showed that males have more segmental sclerosis (P=0.023) and more significant IgM deposits than females (P=0.003). The mean scores of IgA, IgG, and C3 deposited immunological reactants were not substantially different between males and females (P>0.05).
