Objectives: This study was conducted to investigate the effect of rituximab on reducing the panel in transplant dialysis patients. Patients and Methods: This is an interventional study that was conducted on 20 dialysis patients who were candidates for kidney transplantation. Patients first had a panel-reactive antibody test and patients with a panel-reactive antibody above the age of 30 were included in the study. First, rituximab was administered at a dose of one gram and then after two weeks, another dose of one gram was administered. Panel-reactive antibody was measured baseline, one and six months later. Results: One and six months after stopping the drug, we found a significant decrease in the mean amount of reactive antibodies. Additionally, six months after stopping the drug, a significant decrease in the level of patients’ reactive antibodies in comparison to one month before taking the drug was detected (P<0.05). Conclusion: The findings showed that treatment with rituximab is useful for reducing panel-reactive antibody in kidney transplant patients. However, more studies are needed to optimize rituximab injection protocols.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44273696","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: In this study, we investigated the histopathological effects of atorvastatin against gentamicin-induced renal injury. Materials and Methods: Twenty male Wistar rats were randomly assigned into five groups and treated as the following; group 1 (normal group, no drug), group 2 [gentamicin group, daily 80 mg/kg, intra-peritoneal (i.p.) for 7 days], groups 3 to 5 (gentamicin 80 mg/kg + atorvastatin at doses of 5, 25 and 75 mg/kg, respectively). Kidney sections were examined for histopathological parameters including vacuolization of the kidney tubular cells, degeneration, necrosis, flattening of the tubular cells and debris in the tubular lumen. Results: Compared to the normal group, gentamicin significantly exacerbated the histopathological parameters. Treatment with atorvastatin significantly decreased vacuolization, degeneration, necrosis and debris in the nephrotoxic rats. Conclusion: The findings of this research indicated that atorvastatin therapy can ameliorate histopathological renal injury following gentamicin injection.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45466258","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}

Diagnosing LTBI in dialysis patients is helpful in preventing disease evolution. Objectives: The aim of this study was to estimate the frequency of LTBI in a group of hemodialysis patients. Patients and Methods: We studied all patients undergoing hemodialysis in Khorramabad teaching hospitals. Data were collected by completing a questionnaire through observation and interview. The Mantoux tuberculin skin test (TST) was performed, then 48 to 72 hours later, the induration was measured in millimeters. Results equal to or greater than 10 mm were considered positive. Results: One hundred and nineteen patients undergoing hemodialysis participated in the study. The mean age of patients in this study was 58.55 ± 16.04 years. The induration size at the TST site was equal to or greater than 10 mm for 97 patients (81.5%) and less than 10 mm for 22 patients (18.5%). More than 81% of participants had LTBI. Until about two years later, none developed active tuberculosis without preventive treatment. Conclusion: Several studies indicate the uncertainty of TST results in hemodialysis patients. Eighty-two percent positive is too much, and makes it difficult to consider all of them to be true positives. Therefore, it will be challenging to decide on starting preventive treatment. We recommend World Health Organization (WHO) to focus on a new affordable accessible efficient test for LTBI screening which does not require to be repeated or be confirmed by another diagnostic method, especially, for the expanded screening of the general population in the future.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45388100","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 was designed to evaluate the effect of potassium citrate and hydrochlorothiazide on ureteral stent encrustation as a single-blinded clinical trial. Patients and Methods: After embedding ureteral stent in 130 patients, the individuals were randomly divided into two groups using random allocation software. Convenience sampling method was used in this study. One group was given hydrochlorothiazide and potassium citrate, and the other group did not receive any medication. All stents were the same brand and the maximum time of stents being in situ was six weeks. Four to six weeks after stent implantation, patients were referred for stent removal. Then, ureteral stent encrustation was recorded in the two groups according to the visual appearance and the difficulty in stent removing due to stent encrustation. Results: The mean age of the patients was 42.62±14.86 years. Regarding gender, 78 patients (67.8%) were male and 37 patients (32.2%) were female. In this study, 15 patients (13%) had ureteral stent encrustation, of which 13 patients (20%) were in the group without medication and two patients (4%) were in the group who received hydrochlorothiazide and potassium citrate (P = 0.012). Conclusion: The rate of ureteral stent encrustation in the patients who received hydrochlorothiazide and potassium citrate was significantly lower than the patients in the control group. This can be justified by the diuretic properties of hydrochlorothiazide and the reduction of urinary calcium levels. Additionally, high urinary citrate level and induction of urinary alkalization after the administration of potassium citrate. Are the ameliorating factors.

Prevention plays an important role in reducing the complications of acute renal failure (ARF), while changes in fluid therapy management and infection control can reduce the incidence and severity of renal failure. Objectives: The aim of this study was to investigate the prevalence and causes of ARF in children. Patients and Methods: A prospective descriptive-analytical study was conducted in Ali-Ibn-Abitaleb hospital in Zahedan during a period of one year from April to March 2017 in patients aged one month to 15 years who were admitted to the pediatric emergency department. Results: Among 201 patients with acute kidney injury (AKI), the highest number was 112 patients (28.3%) between one month and one year, followed by 80 patients (7.9%), one year to five years, and 9 patients (3.1%) above 5 years. Gender did not play a significant role in the development of acute kidney disease. The most common causes of AKI were sepsis (87.2%), underlying renal disease (64.9%), heart disease (37.5%), and gastrointestinal disease (19.5%), respectively. The most common laboratory findings in patients with AKI were hypokalemia (56.7%) and hypernatremia (57.1%).
