Objective: To assess the clinical outcome of renal transplant patients who developed coronary artery disease and were treated with coronary stenting (TCA-ST).
Methods: A total of 3,334 renal transplants were performed in our service--Hospital do Rim e Hipertensão--HRH (Kidney and Hypertension Hospital) from July, 1998 to November, 2004. During this period, 33 of the renal transplant patients underwent TCA-ST to treat 62 severe stenoses in 54 coronary arteries. A retrospective analysis was performed with renal transplant patients undergoing TCA-ST at HRH. The clinical events were registered using medical charts, medical visits and phone calls.
Results: During the 30-month clinical follow-up after TCA-ST, 67% of the patients remained asymptomatic, 18% presented stable angina, 6% presented acute coronary syndrome without ST-segment elevation (ACSWSTE), and 3% presented acute coronary syndrome with ST-segment elevation (ACSSTE). No strokes, CHF or cardiac deaths were observed. Three non-cardiac deaths occurred. A restenosis rate of 9% was observed, which is comparable to those found in studies on drug-eluting stents.
Conclusion: In conclusion, renal transplant patients who developed CAD and were treated with coronary stenting had a low rate of in-stent restenosis, probably related to the immunosuppressive regimen given to prevent kidney rejection.

Impact of antiviral prophylaxis on EBV viremia and posttransplant lymphoproliferative disorders in solid organ transplant recipients: a systematic review and meta-analysis.

Introduction: Organ transplant recipients face a substantial risk of developing posttransplant lymphoproliferative disorders (PTLD). In over 90% of cases with B-cell PTLD following solid organ transplantation, the Epstein-Barr virus (EBV) genome is promptly identified, usually within the initial year. A continuing discussion revolves around the efficacy of antiviral prophylaxis in mitigating the incidence of PTLD in solid organ transplant (SOT) patients.

Background: Clear cell renal cell carcinoma (ccRCC) is the most common malignant urological tumor, and regrettably, and is insensitive to chemotherapy and radiotherapy, resulting in poor patient outcomes. DBF4 plays a critical role in DNA replication and participates in various biological functions, making it an attractive target for cancer treatment. However, its significance in ccRCC has not yet been explored.

Background: Nephrology referral has been recognized as a modifiable factor influencing patient outcomes. The study aimed to compare clinical outcomes among patients referred early versus late to nephrologists.
Methods: We searched online database from inception to June 1, 2022, to obtain all eligible literature reporting outcomes of patients referred early versus late to nephrologists.
Genetic and clinical spectrum of steroid-resistant nephrotic syndrome with nuclear pore gene mutation.
Pediatr Nephrol
January 2025
Department of Nephrology, Wuhan Children's Hospital (Wuhan Maternal and Child Healthcare Center), Tongji Medical College, Huazhong University of Science & Technology, Wuhan, China.
Background: Steroid-resistant nephrotic syndrome (SRNS) is insensitive to steroid therapy and overwhelmingly progresses to kidney failure (KF), the known pathogenic genes of which include key subunits of the nuclear pore complex (NPC), a less-recognized contributor to glomerular podocyte injury.
Methods: After analyzing their clinical characterizations and obtaining parental consent, whole-exome sequencing (WES) was performed on patients with SRNS. Several nucleoporin (NUP) biallelic pathogenic variants were identified and further analyzed by cDNA-PCR sequencing from white cells of peripheral blood, minigene assay, immunohistochemical (IHC) staining, and electron microscopy (EM) ultrastructure observation of kidney biopsy, as well as multiple in silico prediction tools, including 3D protein modeling.

Background: Patients after kidney transplantation (KTx) in childhood show a high prevalence of cardiac complications, but the underlying mechanism is still poorly understood. In adults, myocardial fibrosis detected in cardiac magnetic resonance (CMR) imaging is already an established risk factor. Data for children after KTx are not available.
