Objectives: The objectives of the study were to assess the effects of GLP1-RA (glucagon-like peptide-1 receptor agonists) and SGLT2i inhibitors therapy on estimated GFR, albuminuria, and weight in patients with DKD stage 3 and 4. Patients and Methods: This was a prospective cohort study of patients with stage 3 and 4 DKD over 6 months at Basra teaching hospital from November 1, 2020, to May 1, 2020. Baseline weight, UACR (urine albumin creatinine ratio), and eGFR were measured, and 6-months values were assessed between and within the group. Results: The baseline characteristics for the GLP-1 RA (GLP-1 receptor agonists) versus SGLT2i (sodium-glucose co-transporter-2 inhibitors) groups were mean ages 65 years versus 62.5 years, male (54.5% versus 50%), median weight (75 versus 80 kg), median eGFR (23.5 versus 39 ml/min/1.73 m2 ) and median UACR (925 mg/g versus 327 mg/g). In the GLP-1 RA group, after 6-months of therapy, there was 32% increase in eGFR (P<0.001), 29% decrease in UACR (P<0.001) and 4.5% decrease in weight while in the SGLT2i group, there was 4.5% decrease in eGFR (P=0.345), 34% decrease in UACR (P<0.001) and 2.8% decrease in weight (P=0.005). With cox-regression analysis, the HR for eGFR decline with SGLT2i therapy was 3.25 (95% CI: 1.1-9.97; P=0.039). Conclusion: GLP-1 RA, compared to SGLT2i therapy, caused an increase in eGFR in stages 3 and 4 CKD and caused more weight reduction but slightly less albuminuria reduction.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135236339","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}

Creatinine and neutrophil gelatinase-associated lipocalin (NGAL) are the most commonly conducted biomarkers of AKI. Objectives: The aim of current study was to assess NGAL as an early biomarker for AKI diagnosis following contrast agents. Patients and Methods: To follow the aim of the present case-control research, 165 individuals were entered the study; 80 patients were selected from Valiasr hospital of Zanjan city, and 85 healthy individuals were enrolled voluntarily. There were not any significant differences in sex distribution among healthy subjects. Plasma NGAL and creatinine were measured immediately before and at 12 and 72 hours post-contrast agents’ exposure. Results: There were 89 males and 76 females in the study groups. The mean age was 61.3 ± 18.2 years and 62.1 ± 17.2 years in the intervention and healthy groups, respectively. The mean of serum creatinine and NGAL level were 1.0± 0.2 mg/dL and 63.6 ±23.6 ng/mL in the control and 0.92 ± 0.23 mg/dL and 110 ± 82.3 ng/mL in the case group, respectively. There were remarkable different between serum NGAL and creatinine in the both groups. The NGAL level in the healthy and the patient group were 63.6 ± 23.6 ng/mL and 100.1 ± 121.7 ng/mL, respectively, which was considerably different between the case and control groups (P=0.01). The highest level of specificity and sensitivity were 86 and 55.5; they could be the main appropriate options for defining cut off. Conclusion: The findings showed, that NGAL level is an extremely specific and sensitive indicator for AKI diagnosis after 72 hours. Hence, this approach can open a novel insight into the AKI therapies.","PeriodicalId":16950,"journal":{"name":"Journal of Renal Injury Prevention","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47858840","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: We aimed to compare the efficacy of tadalafil in three groups: hemodialysis (HD) patients, first KT recipients (KT1) and second KT recipients (KT2) with bilaterally ligated internal iliac arteries (IIAs). Patients and Methods: Age-matched men with ED were included in the study. Patients divided into three groups; HD, KT1 and KT2. The international index of erectile function 15 (IIEF-15) questionnaire was used to assess the baseline erectile function. Tadalafil was administered in a dose-escalation method for three months. Patients were reevaluated by the questionnaire at three months. The mean score evolution was compared between the study groups by Kruskal-Wallis H test. Results: Total number of 106 patients in three groups was included in the final analysis. There was no significant difference between the study groups in terms of age, body mass index (BMI), blood pressure and frequency of smoking, opium, or alcohol use. Tadalafil was safe and effective in all three groups. The mean IIEF score evolution in HD, KT1 and KT2 groups was 16.4 (58.7% increase from baseline), 19.3 (45.0% increase) and 20.4 (52.7% increase), respectively. Conclusion: Tadalafil is effective and safe in the management of ED even after the second kidney transplantation when the IIAs are cut bilaterally.

The data were statistically analyzed by STATA 14 software. The significance level of the tests was considered P<0.05. Results: In 15 reviewed articles, 46 735 subjects used statin, and 673 752 did not.

Long-term and/or high dose furosemide may lead to acute kidney injury. Objectives: We aimed to find the risk of AKI among hospitalised patients who were exposed to furosemide. Patients and Methods: This is a retrospective cohort study of hospitalised patients who received furosemide therapy during the admission between 2019 and 2021. Exposure to furosemide was grouped into low dose (≤ 40 mg/d) or high dose (>40 mg/d) and short-term use (≤ 72 hours) or long-term use (>72 hours). Risk of acute kidney injury was calculated as odds ratios with a 95% confidence interval (CI). A P value <0.05 was considered statistically significant. Results: Of 314 patients who received furosemide intravenously or orally, 197 patients (62.7%) had acute kidney injury. Of 197 patients with acute kidney injury, 110 patients (55.9%) received the dosage of >40 mg/d and 121 patients (61.4%) were on furosemide for >7 days (odds ratios [ORs]: 5.46, 95% CI: 3.17 to 9.39, P≤0.001 and ORs: 7.72, 95% CI: 4.4 to 13.52, P≤0.001).

Conclusion: Among hospitalised patients, exposure to high dose furosemide or prolonged use of furosemide is associated with AKI. The risk is more when high dose furosemide is administered for longer than 72 hours.
