Study of the renal function in nonrenal organ transplantation.

Kidney disease after transplantation of a nonrenal organ has been described to be the result of the nephrotoxicity from the commonly used calcineurin-inhibitors as well as other factors. The aim of this study was to evaluate renal function and potential risk factors for the development of chronic renal failure among nonrenal organ recipients. We designed a single-center retrospective study including all 165 of our cardiac and liver recipients between February 1998 and October 2003, collecting clinical, analytic, and therapeutic data.

Posttransplantation diabetes mellitus: prevalence and risk factors.

Background: Prevalence of diabetes mellitus (DM) type 2 in Asturias is 10%. The associations between age, family history of diabetes, hypertension, obesity, hypertriglyceridemia, and development of type 2 diabetes are well established. The aim of this study was to evaluate the prevalence of and risk factors for posttransplantation diabetes mellitus (PTDM).

Risk factors for cardiovascular disease during the first 2 years after renal transplantation.

The aim of the present study was to assess the role of cardiovascular risk factors in the occurrence of cardiovascular events among 100 consecutive renal transplant recipients during the first 2 years after transplantation. The following parameters were analyzed: (1) demographic data (gender, age, dialysis duration, preexistent diabetes, and pretransplantation events) as well as (2) basal 1-year, and 2-year posttransplantation data for events, body mass index, arterial hypertension, number of drugs for hypertension control, use of ACE or ARA II inhibitors, treatment with lipid- lowering drugs, de novo diabetes, anemia, immunosuppression with cyclosporine versus tacrolimus, and homocysteine, folic acid, serum creatinine, uric acid, PTH-i, and cholesterol total, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, and triglyceride levels. At the end of the second posttransplantation year, 14 patients versus 86 who did not experience a new cardiovascular event.

[Parvovirus B9 infection in a renal transplant recipient. Diagnosis by detection of viral genome in peripheral blood].

Parvovirus B19 can produce a picture known as pure red blood aplasia in recipients of solid organ. Occasionally the viruses cause decrease of the other blood cells, and various extra-hematologic manifestations. Common diagnosis is realised by bone marrow examination.

The timely construction of arteriovenous fistulae: a key to reducing morbidity and mortality and to improving cost management.

Background: Some investigators have shown that the initial placement of a catheter or graft, instead of the timely construction of an arteriovenous fistula (AVF), late referral to nephrology services and unplanned dialysis increase morbidity and mortality in chronic haemodialysis (CHD) patients. Furthermore, a delay in providing an adequate AVF entails significant increases in treatment-related costs. This study was limited to the analysis of the effects of the lack of an adequate vascular access for CHD on morbidity and mortality.

Influence of anticalcineurinic therapy in plasma homocysteine levels of renal transplant recipients: a prospective study.

Hyperhomocysteinemia is an independent factor for cardiovascular disease. Renal function and folate level are important determinants of total plasma homocysteine levels. The influence of anticalcineurin drugs on homocysteine levels is controversial.

[Remission of severe disease induced by CMV and lymphoproliferative post-transplant disease after changing the immunosuppressive regime].

We describe a renal transplant recipient, with overimmunosuppression induced by the interaction of tacrolimus and fluconazole, who developed two severe diseases produced by two different viruses of the herpes group (cytomegalovirus [CMV] disease and posttransplant lymphoproliferative [PTLD] disease EBV-related). Detection of Epstein-Barr virus (EBV) DNA in the blood preceded the histological diagnosis of PTLD. Both diseases improved after changes in the immunosuppressive regime and treatment with ganciclovir.

[Changes in health-related quality of life in the first year of kidney transplantation].

Objective: To study the changes in the health related quality of life (HRQOL) during the first year following renal transplant (RT), comparing azathioprine vs mycophenolate mofetil (MMF) in triple immunosuppressant therapy with prednisone and cyclosporine.

Methods: Prospective, open and random study with 26 patients who received a primary cadaveric renal transplant consecutively. Analysis of clinical variables: delayed graft function (DGF), acute rejection (AR), infections and comorbidity; analytical: haemogram, albumin and serum creatinine, hepatic function, cyclosporin levels; instruments for assessing the HRQOL: Psychological General Well-being Index (PGWBI) and Euroqol-5d (EQ-5d) health questionnaire, which includes a self-assessment scale of the state of health, Visual Analogical Scale (VAS).

Is the loss of health-related quality of life during renal replacement therapy lower in elderly patients than in younger patients?

Background: Previous studies have reported that elderly (aged 65 years or over) end-stage renal disease (ESRD) patients have poorer health-related quality of life (HRQOL) than both younger patients and healthy subjects of the same age. The aim of present study was to evaluate the effect of ESRD and its treatment on the HRQOL, and to determine the effects of age and gender.

Methods: A cross-sectional multicentric study was carried out with 485 haemodialysis and renal-transplant patients, using the SF-36 Health Survey to evaluate their HRQOL.

[Preeclampsia and peripartum cardiomyopathy: infrequent association].

Peripartum cardiomyopathy (PPCM) is a rare form of congestive heart failure that affects women late in pregnancy or in the early puerperium. PPCM is a disorder of unknown etiology that can have potentially devastating consequences. Although the etiology of PPCM remains unclear, a number of risk factors for this disorder have been proposed.

Health related quality of life (HRQOL) of kidney transplanted patients: variables that influence it.

Unlabelled: The incidence and prevalence of patients on renal replacement therapy (RRT) who receive a renal transplant are continuously increasing in Spain. At the moment, they are the main group of end-stage renal disease (ESRD) patients in our region (60% of total RRT patients). The aim of the present study was to assess the health related quality of life (HRQOL) of kidney transplanted patients of our region, and to identify socio-demographic and clinical variables that influence it.

Control of cytomegalovirus disease in renal transplant patients treated with prednisone, azathioprine and cyclosporine using intensive monitoring and decreased immunosuppression.

Background: The aim of this trial was to study the effectiveness of intensive monitoring, together with an early decrease in immunosuppression, in reducing the prevalence of CMV disease in renal transplant recipients treated with prednisone, azathioprine and cyclosporine.

Methods: From 1/95 to 11/97 a prospective, longitudinal study was conducted among 146 consecutive, unselected, renal transplant patients in our unit. Only 96 patients whose immunosuppressive regimens consisted of prednisone, azathioprine and cyclosporine and whose follow-up period was greater than 4 months were included in the study.

Disseminated herpes simplex virus infection in a renal transplant patient as possible cause of repeated urinary extravasations.

Disseminated herpes simplex virus type 2 (HSV-2) infections are infrequent in patients receiving organ transplants, but usually have a poor outcome. We describe the case of a renal transplant patient who developed a disseminated HSV-2 infection with repeated urinary extravasations. The diagnosis was carried out using a multiplex polymerase chain reaction nested assay and it suggested HSV-2 as a possible cause of repeated urinary fistulas.

Health-related quality of life (HRQOL) in end stage renal disease (ESRD) patients over 65 years.

Objectives: The aim of the study was to assess Health Related Quality of Life (HRQOL) of elderly patients on renal replacement therapy (RRT) of our region, and to identify socio-demographic and clinical variables which influence it. We also attempted to compare HRQOL of transplant patients, with that of chronic hemodialysis patients.

Design: Cross-sectional study.

Hyperthyroidism in a renal transplant recipient.

We report a case of toxic multinodular goiter with severe symptomatic hyperthyroidism in a female diagnosed 5 months after successful renal transplantation. To our knowledge, this is the first well-documented case of hyperthyroidism in a renal transplant recipient that responded well to methimazole. Special attention should be made to the use of methimazole and the possible interaction with immunosuppressive drugs.
