Background: Persistent post-transplant hyperparathyroidism (PPTHP) can occur in 20% to 50% of renal transplant recipients. The aim of this study was to analyze safety and efficacy of long-term cinacalcet therapy in a group of renal transplant recipients with PPTHP.
Methods: A single center retrospective cohort study including renal transplant recipients, adults (>18 years old) with PPTHP and hypercalcemia. Inclusion criteria for cinacalcet therapy was increased parathormone levels (PTH > 65 pg/mL) associated with serum calcium >11.5 mg/dL any time after transplant or calcium >10.2 mg/dL within the first year after transplant. The follow-up period was 3 years. Demographic, laboratory data and adverse events were assessed.
Results: Forty-six patients were included, mean age of 50 ± 11 years old, majority of white race (60%), male (58%), with a pretransplant length on dialysis of 67 ± 34 months. Cinacalcet therapy was started 37 ± 40 months after transplant, and normal calcium levels were achieved after 6 months of therapy. PTH levels presented a steady reduction over time, reaching levels near normal after 36 months (317 ± 242 vs 145 ± 72 pg/mL, baseline × month 36, P < .05). Renal function remained stable over time (GFR > 60 mL/min/1.73 m) and no acute rejection episodes were observed. Most common adverse events were mild gastrointestinal symptoms. In 6 patients (12.5%) treatment was interrupted due to adverse events. Only 1 case (2%) was classified as treatment failure.
Conclusion: Cinacalcet therapy proved to be efficient for PPTHP and safe for graft and patient. Long-term treatment reduced PTH levels to near normal range.

Highly sensitized (HS) patients in need of kidney transplantation (KTx) typically spend a longer time waiting for compatible kidneys, are unlikely to receive an organ offer, and are at increased risk of antibody-mediated rejection (AMR). Desensitization using imlifidase, which is more rapid and removes total body immunoglobulin G (IgG) to a greater extent than other methods, enables transplantation to occur between HLA-incompatible (HLAi) donor-recipient pairs and allows patients to have greater access to KTx. However, when the project was launched there was limited data and clinical experience with desensitization in general and with imlifidase specifically.

Background: Currently, there are no standardized guidelines for graft allocation in heart transplants (HTxs), particularly when considering organs from marginal donors and donors after cardiocirculatory arrest. This complexity highlights the need for an effective risk analysis tool for primary graft dysfunction (PGD), a severe complication in HTx. Existing score systems for predicting PGD lack superior predictive capability and are often too complex for routine clinical use.

We report a case of GIN and de novo FSGS in kidney transplant recipients leading to allograft failure. A 69-year-old male with a history of end-stage renal disease (ESRD) of unknown etiology, as well as liver failure from hepatitis B and C co-infection, initially had a living unrelated kidney transplant (LURT) in 2007 and subsequently received both liver and kidney transplants (SLKTs) in 2017.

Diagnosis of tuberculous spondylodiscitis is difficult because clinical findings usually are nonspecific and radiological features may mimic other bacterial, fungal, inflammatory and neoplastic diseases. We present the first reported case of tuberculous spondylodiscitis in a 56-year-old man successfully treated by rifampicin-containing anti tuberculosis regimen with close follow-up of serum cyclosporine levels.

Background: Aortoiliac screening before kidney transplantation is suggested by some guidelines to select patients for transplantation and to assist surgical planning. We investigated the clinical outcomes of systematic screening for aortoiliac disease in potential kidney transplant candidates.
Methods: In this observational study, 470 potential kidney transplant candidates underwent aortoiliac computed tomography angiography.
