Clinical value of adding Dapagliflozin in patients with nephrotic syndrome.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors in nephrotic patients on immunosuppression are underexplored. We evaluated dapagliflozin's impact in non-diabetic primary nephrotic syndrome. METHODS: Randomized controlled clinical trial was conducted on 60 non-diabetic primary nephrotic syndrome patients, equally assigned to dapagliflozin and control groups. All patients received the standard of care medication and the Dapagliflozin group received 10 mg dapagliflozin in addition. Demographic data, nephrotic syndrome etiology, proteinuria levels, eGFR, and immunosuppression doses, were well-matched. After 6 months of follow up primary outcomes included changes in and eGFR. RESULTS: Both groups exhibited significant reductions in proteinuria after 6 months, with the dapagliflozin group achieving a mean UPCR reduction of - 94.7%, and the control group - 86.7% (p < 0.001). However, the comparative change in proteinuria between both groups did not reach statistical significance (p = 0.158). Dapagliflozin initially led to a transient eGFR decline. Dapagliflozin also resulted in a significant mean body weight reduction (p < 0.001) and notable improvements in triglyceride levels compared to the control group (p = 0.045). CONCLUSION: In primary nephrotic syndrome patients, adjunct dapagliflozin may enhance the standard of care. While notable, the reduction in proteinuria was comparable to that of the control group by the study's end. Furthermore, after 6 months, eGFR remained stable in both groups. However, significant weight loss and serum triglyceride reduction were particularly pronounced in the dapagliflozin group. Further long-term investigations are necessary to address potential immunosuppression-related confounding effects in patients with primary glomerular disease.

Prevalence of Asymptomatic COVID-19 Infection in Hemodialysis Patients and the Risk of Hypercoagulability: Should we Consider Routine Screening?

Introduction: Coronavirus disease 2019 (COVID-19) has become a pandemic in late 2019. Its clinical presentation varies from asymptomatic infection to severe respiratory failure. Infection control strategies to minimize the risk of transmission of COVID-19 in end-stage renal disease (ESRD) patients receiving in-center hemodialysis (HD) have been implemented. Development of humoral response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in adult patients with ESRD receiving HD has not been sufficiently reported. Methods: A total of 179 asymptomatic HD patients undergoing regular HD were screened for COVID-19 infection. Infection with SARS-CoV-2 was confirmed through a real-time reverse transcription polymerase chain reaction assay of nasopharyngeal swab specimens. They were classified into positive and negative groups according to the results of PCR. Results: Of the 179 asymptomatic patients, we found that 23 patients (12.8%) were positive for COVID-19. Their mean age was 45.61 ± 13.38 years. There was a significant difference between both groups regarding C-reactive protein, lymphocytes, and platelet counts (P < 0.001). Also, TAT (thrombin-antithrombin complex) and D-dimer levels were significantly increased among the positive group (11.47 ± 1.51 vs. 7.53 ± 1.64 mcq/L, P < 0.001; 1171.52 ± 267.6 vs. 542.76 ± 107.06 ng/mL, P < 0.001, respectively). Conclusion: Asymptomatic SARS-CoV-2 infection is detected in HD patients. They carry the risk of hypercoagulability complications. We need more strict infection control measures and proactive diagnosis to limit the spread of the infection and lethal thromboembolic complications.

Renoprotective effect of febuxostat on contrast-induced acute kidney injury in chronic kidney disease patients stage 3: randomized controlled trial.

INTRODUCTION: Contrast-induced acute kidney injury (CI-AKI) is known to be a complication of using intravascular contrast injection. Unfortunately, it is associated with adverse outcomes such as prolonged length of hospitalization and increased burden of health care costs. So, we aimed to determine the efficacy of febuxostat in the prevention of contrast-induced acute kidney injury among patients with chronic kidney disease Stage 3 performing percutaneous coronary intervention (PCI). METHODS: In a randomized controlled trial we enrolled 120 CKD stage 3 Patients with acute coronary syndrome referred to the cardiology department Ain-Shams University hospital for performing PCI and stenting. Patients were randomly assigned to two arms: Group I (study group): Included 60 patients who received Febuxostat added to the traditional treatment (IV hydration and N-acetylcysteine). The patients received Feburic 80 mg within 6-18 h before and within 6-18 h after the coronary intervention (a time gap of 24 h between two doses). Group II (control group): included 60 patients who received only traditional treatment. RESULTS: The incidence of AKI was higher in the control group with a statistically significant difference. We found that Independent Significant risk factors that led to AKI were febuxostate avoidance, DM, high urea level, high creatinine level, CKD stage 3B, high Mehran score and high AKI risk. CONCLUSION: We demonstrated that febuxostat has a Reno protective effect and it can help to reduce the incidence CI-AKI in CKD patients stage 3 performing PCI.

Value of Plasmatic Villin-1 in the Prediction of Early Graft Dysfunction in Kidney Transplant Recipients: Diagnostic Accuracy Test.

OBJECTIVES: One of the complications of kidney transplant is delayed graft function. Villin-1 has been detected in urine of patients with acute kidney injury. In addition, it is redistributed during acute kidney injury from the brush borders of the proximal tubular cells toward the basolateral membrane, which positions villin-1 closer to the renal vasculature, suggesting that it could be also released in the blood and thus can be a novel biomarker for delayed graft function. MATERIALS AND METHODS: In this diagnostic accuracy test multicenter study, 41 patients undergoing kidney transplant and attending renal transplant clinics were assigned into 2 groups according to serum creatinine levels during the first 2 days posttransplant: delayed graft function group and normal graft function group. We measured plasmatic villin-1 in comparison to serum creatinine levels at the time of declamping (time 0) and at 1, 3, 5, 7, 12, 24, 48, 72, 96, and 120 hours after declamping. RESULTS: Statistically significant differences were noted in comparisons between groups at same time points with regard to plasmatic villin-1 levels; also, plasmatic villin-1 started to increase above reference range in patients with end-stage renal disease at 5 hours after declamping; a peak was shown at hour 7 in the delayed graft function group, which decreased but did not reach the reference range until 120 hours after declamping. CONCLUSIONS: Plasmatic villin-1 is a promising novel biomarker for detection of early graft dysfunction in kidney transplant recipients.
