The patient was on peritoneal dialysis from 2008 to 2016, when he underwent renal transplantation. Transplant duration was less than a month due to acute vascular rejection. Since then, he is on hemodialysis. A few months after transplantation, it was incidentally identified confluent bilateral opacities, more prominent on the left lung in a routine X-ray (Figure 1). The patient had made a chest radiography in 2015 without any changes at that time. The CT scan showed parenchymatous densification areas, partially calcified, in both lungs (Figure 2). The patient also developed secondary hyperparathyroidism refractory to medical therapy but refused surgery. Nevertheless, the lesions had a slow progression until the present time.","PeriodicalId":91451,"journal":{"name":"Austin journal of nephrology and hypertension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44549513","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}

Methods: The chronic stress model was established in male Sprague Dawley (SD) rats by foot shock for two weeks. Rats were randomly divided into control group, chronic stress group, renal denervation group, renal denervation plus chronic stress group, captopril (an angiotensin I converting enzyme inhibitor, ACEI) plus chronic stress group and tempol (a superoxide dismutase mimetic) plus chronic stress group. Body weight, food intake, water intake, blood pressure and heart rate were monitored. Real-time PCR was used to detect the mRNA level of AQP1 in the renal tissue. Immunohistochemistry stain was used to observe the expression and location of AQP1 in rat kidneys. Results: Chronic stress reduced body weight gain and food intake, while it significantly increased systolic blood pressure and renal expressions of mRNA and protein of AQP1 (P<0.05) as compared with control group. Renal denervation and tempol treatments did not affect stress-induced decreases of body weight gain and food intake. Renal denervation, captopril and tempol treatments decreased systolic blood pressure. Compared with the chronic stress group, mRNA and protein expression of AQP1 was decreased (P<0.05) in renal denervation plus chronic stress group, captopril plus chronic stress group and tempol plus chronic stress group. Conclusion: Chronic stress induces increase of the AQP1 expression in kidney, which is regulated by renal nerve system, renin-angiotensin system and oxidative stress.","PeriodicalId":91451,"journal":{"name":"Austin journal of nephrology and hypertension","volume":"24 31","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41256291","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}

The quality of care these patients receive remains uncertain. Methods: This is a descriptive, single-center and cross-sectional cohort study. The KDOQI performance measures, hemoglobin level >11 g/dL, blood pressure <140/90 mmHg, serum albumin >4 g/dL and use of arteriovenous fistula of patients with ESRD on hemodialysis were analyzed in a period of a year. The association between mortality and the KDOQI objectives was evaluated with a logistic regression model. A linear regression model was also performed with the number of readmissions. Results: A total of 124 participants were included. Participants were categorized by the number of measures completed. Fourteen (11.3%) of the participants did not meet any of the goals, 51 (41.1%) met one, 43 (34.7%) met two, 11 (8.9%) met three, and 5 (4%) met the four clinical goals analyzed. A mortality of 11.2% was registered. In the logistic regression model, the number of goals met had an OR for mortality of 1.1 (95% CI 0.5-2.8). In the linear regression model, for the number of readmissions, a beta correlation with the number of KDOQI goals met was 0.246 (95% CI -0.872-1.365). Conclusion: The attainment of clinical goals and the mortality rate in our center is similar to that reported in the world literature. Our study did not find a significant association between compliance with clinical guidelines and mortality or the number of hospital admissions in CKD patients on hemodialysis.","PeriodicalId":91451,"journal":{"name":"Austin journal of nephrology and hypertension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48083679","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}

Therefore, kidney biopsy is essential to make this diagnosis. We made a retrospective study, which aimed to: 1. Identify dysproteinemiaassociated kidney lesions; 2. Establish clinicopathological correlations of patients with those lesions and 3. Identify kidney and patient survival predictors. Methods: A retrospective, observational chart review of kidney biopsies performed, between January 2015 and February 2020, in three Portuguese Hospitals, to a total of 39 patients, with kidney lesions associated with monoclonal gammopathy, was undertaken. Results: The three main dysproteinemic kidney diseases identified were cast nephropathy, AL amyloidosis and Monoclonal Immunoglobulin Deposition Disease (MIDD), with different features among them. Only three patients fulfilled the criteria to Monoclonal Gammopathy of Renal Significance (MGRS). In regard to treatment, we verified that most of our patients were treated with chemotherapy. Unfortunately, only four recovered, either partially or completely. The mean kidney survival since kidney biopsy was 29,23 months and the mean patient survival since diagnosis was 24,46 months. Some clinical and pathologic features correlated to lowerkidney survival: acute tubular necrosis, cast nephropathy, Thrombotic Microangiopathy (TMA), haemoglobin and estimated Glomerular Filtration Rate (eGFR). Previous Nephrology follow-up correlated with higher kidney survival. Only eGFR was associated with lowerpatient survival.","PeriodicalId":91451,"journal":{"name":"Austin journal of nephrology and hypertension","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45801235","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}

HD complications occur during HD, post-HD session, and at long term. Aim of the Study: To assess frequency of common complications that occur during HD-session. Method and Patients: Study planned to assess the complications happened during HD-session for 335 patients. All patients had been informed about study aim. All patients included had not any evidence of HBV, HCV or HIV infection. Patient had their weight, blood pressure, pulse, Random Blood Sugar (RBS) and body temperature before they sat on HD-bed. Regular checkup of vital signs every 30 minutes. Any change of these parameters were recorded. Other parameters as hypoglycemic feature, hypotension, rigor, hotness and others were noted. Statistical Analysis: After data collection and arrangement in Excel sheet of Microsoft Office version 16, frequency and average of the parameters are calculated by IBM-SPSS version 25 (SPSS, Chicago, IL, USA) statistical package. Results: Three hundred thirty-five patients enrolled. They were 132 females and 203 male patients, aged 31- 56 years (48 ± 5.2), and weight range was 51-76 Kg (66 ± 3.4). There were 156 patients; 46 hypertensive, 62 diabetics, and 48 diabetics and hypertensive. The rest were not hypertensive or diabetic. Vomiting reported in (61.8%) of patients; during 1 st hour, vomiting occurred in (40.9%) of patients. During 2 nd and at 3 rd hour of HD-session, patients had vomiting almost the same number during this time of HD session. Epigastric mostly three sessions per week.
