Vascular Proliferation

Kaposi Sarcoma (KS) is driven by human herpes virus 8 causing vascular proliferation which is induced by loss of immune function most often due to HIV or immunosuppressants. KS occurs with increased incidence in kidney transplant recipients, but rarely is disseminated. We report a 64-year-old male who developed severely disseminated KS 5 months after ABO-incompatible kidney-transplantation. No guidelines for chemotherapy exist in this case and reduced kidney function and impaired immune system complicates the use of systemic chemotherapy in kidney transplant recipients. A combination of paclitaxel and gemcitabine followed by two days of hemodialysis treatment was chosen since paclitaxel can be given in full dose independently of kidney function and gemcitabine is metabolised to 2′,2′-difluorodeoxyuridine which is found to be highly dialysable. The present treatment was well tolerated by the patient with one episode of leukopenia and elevated alanine transaminase during treatment which resolved. There were no serious adverse events and the patient obtained a complete remission verified by Positron Emission Tomography CT after ending chemotherapy and at one-year follow up.

Introduction: The FOXP3 protein is an immune regulatory protein that specifically maintains the function and differentiation of regulatory T cells (Tregs) and prevents autoimmunity. Variations in FOXP3 gene may alter its function and also the immune response. Objectives: The present study was conducted to investigate the association of the FOXP3 gene polymorphisms -3499 A/G and -3279 A/C with renal allograft function and survival in kidney transplant recipients. Patients and Methods: In this cross-sectional study, 150 eligible kidney transplant recipients were evaluated. Kidney function was evaluated at three- and five-year post-transplant using serum creatinine level and glomerular filtration rate as indicators. Genotyping of the study participants was performed using the PCR– restriction fragment length polymorphism method. Results: The frequencies of AA, AG, and GG genotypes of the -3499 A/G polymorphism were 62.42%, 29.53%, and 8.05%, respectively. For the -3279 A/C polymorphism, the frequencies of the AA, AC, and CC genotypes were 21.33%, 32%, and 46.67%, respectively. The mean ± SD of serum creatinine level, three and five years after transplantation were 1.70 ± 1.58 and 1.87 ± 1.94, respectively. Serum creatinine level and kidney function did not show any significant association with these polymorphisms. Conclusion: In the present study, only 10% of participants experienced episodes of severe kidney dysfunction and we did not find any significant association between kidney function and the subjects’ genotypes. Further epidemiologic studies with greater sample sizes may be needed to clarify this association.

Background and objectivesDespite improvement of short-term graft survival over recent years, long-term graft survival after kidney transplantation has not improved. Studies in the general population suggest the Mediterranean diet benefits kidney function preservation. We investigated whether adherence to the Mediterranean diet is associated with kidney outcomes in kidney transplant recipients.Design, setting, participants, & measurementsWe included 632 adult kidney transplant recipients with a functioning graft for ≥1 year. Dietary intake was inquired using a 177-item validated food frequency questionnaire. Adherence to the Mediterranean diet was assessed using a nine-point Mediterranean Diet Score. Primary end point of the study was graft failure and secondary end points included kidney function decline (doubling of serum creatinine or graft failure) and graft loss (graft failure or death with a functioning graft). Cox regression analyses were used to prospectively study the associations of the Mediterranean Diet Score with study end points.ResultsDuring median follow-up of 5.4 (interquartile range, 4.9–6.0) years, 76 participants developed graft failure, 119 developed kidney function decline, and 181 developed graft loss. The Mediterranean Diet Score was inversely associated with all study end points (graft failure: hazard ratio [HR], 0.68; 95% confidence interval [95% CI], 0.50 to 0.91; kidney function decline: HR, 0.68; 95% CI, 0.55 to 0.85; and graft loss: HR, 0.74; 95% CI, 0.63 to 0.88 per two-point increase in Mediterranean Diet Score) independent of potential confounders. We identified 24-hour urinary protein excretion and time since transplantation to be an effect modifier, with stronger inverse associations between the Mediterranean Diet Score and kidney outcomes observed in participants with higher urinary protein excretion and participants transplanted more recently.ConclusionsAdherence to the Mediterranean diet is associated with better kidney function outcomes in kidney transplant recipients.

K Deficiency

High circulating dephosphorylated (dp) uncarboxylated (uc) matrix Gla protein (MGP) and uc osteocalcin (OC) concentrations are regarded as markers of vitamin K-deficiency. However, because MGP and OC are small molecules, they may potentially pass the glomerulus, and their blood concentrations may strongly depend on kidney function. However, many studies with vitamin K-status parameters do not structurally adjust for baseline kidney function, and detailed studies on kidney function-dependence of vitamin K-status markers are lacking. We therefore measured plasma dp-ucMGP using a chemiluminescent assay in 578 kidney transplant recipients (41% females, age 56 ± 13y, 7.5 (3.2 to 13.7)y after transplantation, eGFR 49 ± 17 mL/min/1.73 m2) participating in the prospective TransplantLines Cohort Studies. Additionally, dp-carboxylated MGP, ucOC and carboxylated OC were measured using ELISA in plasma of a subgroup of 60 participants. Finally, dp-ucMGP was measured in a separate cohort of 124 kidney transplant recipients before and three months after kidney transplantation. Dp-ucMGP positively correlated with creatinine, cystatin C, and negatively with eGFR (Spearman’s ρ 0.54, 0.60, and −0.54, respectively, p < 0.001 for all), and each 10 mL/min/1.73 m2 increase in eGFR was associated with a 14.0% lower dp-ucMGP. Additionally, dp-ucMGP strongly declined after kidney transplantation (pretransplantation: 1252 (868 to 1744) pmol/L to posttransplantation: 609 (451 to 914) pmol/L, p < 0.001). Proportions of dp-ucMGP over total MGP and ucOC over total OC were not associated with eGFR. This study highlights that dp-ucMGP is strongly associated with kidney function, and that levels strongly decrease after kidney transplantation. We therefore propose adequate adjustment for kidney function, or the use of kidney function-independent parameters such as proportion of uncarboxylated MGP or OC in the assessment of vitamin K-status in clinical practice and research.
