Dengue in renal transplant patients: a retrospective analysis.

We reviewed the impact of dengue in 27 renal transplant recipients (9 females and 18 males) at a mean of 63 (6-287) months after transplantation. Their mean age was 37+/-14 years and all were first transplantations (21 live donors, 6 deceased donors). Twenty-six were dengue fever cases and one had dengue hemorrhagic fever. Symptoms were: fever (100%), muscular pain (90%), malaise (75%), and headache (68%). Eight (29%) patients were admitted to hospital with one death. All other cases had full recovery. Mean serum creatinine before dengue was 1.4+/-0.6 mg/dL, increased to a mean peak of 1.9+/-1.2 mg/dL (P<0.001), and returned to baseline after recovery (1.6+/-0.82 mg/dL, P=NS). After a mean follow-up of 39+/-18 months, four patients lost their grafts due to chronic allograft nephropathy and four died, due to infectious causes not related to dengue. The first episode of dengue in transplanted patients resembled a flu-like syndrome, as in the general population. It did not cause long-term damage to either the patient or the graft.

Evaluation of renal function in a specific population of living kidney donors.

BACKGROUND: The increase in candidates for kidney transplant has led to growth in the number of living donor transplants. Therefore, studies that adequately evaluate the possible long-term consequences of elective transplant nephrectomy are needed. OBJECTIVE: To evaluate the possible long-term adverse effects of transplant nephrectomy on the renal function of living kidney donors. DESIGN: A cross-sectional study. PARTICIPANTS: Thirty-three living kidney donors registered in the transplant programme of a centre in Alagoas, Brazil. MEASUREMENTS: Demographic characteristics, anthropometric measures, clinical data and biomarkers (creatinine, eGFR, microalbuminuria, cholesterol and triglycerides) were measured. Creatinine clearance was calculated using the Cockcroft-Gault and Modification of Diet in Renal Disease formulae. RESULTS: Of the 33 individuals, 63.63% were female, and the median age was 45 years. Additionally, 24.24% of these individuals had altered blood pressure, 39.39% had altered abdominal circumference (AC) and 36.36% were obese, with a body mass index ≥30. Furthermore, 33.33% of these individuals had elevated triglyceride levels. The average eGFR was 97.33 (33.03-175.9) ml/min/1.73 m2 (CG) and 84.14 (29.4-131) ml/min/1.73 m2 (MDRD). The microalbuminuria level was altered in 12.12% patients. CONCLUSION: Kidney donation is unquestionably a safe procedure. However, a better understanding of the long-term consequences of living donor kidney transplantation is still needed. This knowledge may have important implications for the follow-up of these patients. Our study has demonstrated a non-negligible presence of an early marker of glomerular injury and a decrease in the GFR of some patients, thereby reinforcing the proposal for long-term follow-up of living kidney donors.
