title: Tuberculosis in renal transplant patients: The experience of a single center in Medellín-Colombia, 2005-2013

description: Introduction: Tuberculosis is a common opportunistic infection in renal transplant patients. Objective: To obtain a clinical and laboratory description of transplant patients diagnosed with tuberculosis and their response to treatment during a period ranging from 2005 to 2013 at the Pablo Tobón Uribe Hospital. Methods: Retrospective and descriptive study. Results: In 641 renal transplants, tuberculosis was confirmed in 12 cases. Of these, 25% had a history of acute rejection, and 50% had creatinine levels greater than 1.5 mg/dl prior to infection. The disease typically presented as pulmonary (50%) and disseminated (33.3%). The first phase of treatment consisted of 3 months of HZRE (isoniazid, pyrazinamide, rifampicin and ethambutol) in 75% of the cases and HZME (isoniazid, pyrazinamide, moxifloxacin and ethambutol) in 25% of the cases. During the second phase of the treatment, 75% of the cases received isoniazid and rifampicin, and 25% of the cases received isoniazid and ethambutol. The length of treatment varied between 6 and 18 months. In 41.7% of patients, hepatotoxicity was associated with the beginning of anti-tuberculosis therapy. During a year-long follow-up, renal function remained stable, and the mortality rate was 16.7%. Conclusion: Tuberculosis in the renal transplant population studied caused diverse nonspecific symptoms. Pulmonary and disseminated tuberculosis were the most frequent forms and required prolonged treatment. Antituberculosis medications had a high toxicity and mortality. This infection must be considered when patients present with a febrile syndrome of unknown origin, especially during the first year after renal transplant.

title: Effect of renal revascularization on the development of renal dysfunction in atherosclerotic ischemic nephropathy

description: Chronic kidney disease (CKD) is characterized by a progressive loss of renal function and its main causes are hypertension and diabetes mellitus. Among the causes of hypertension is atherosclerotic renal disease (ARD). The development of CKD in patients with ARD appears to be due not only to the involvement of the main renal arteries, but also of the renal microcirculation, which may explain the fact that the success of the procedure does not guarantee an improvement in the progression of CKD. To date there is no evidence of benefit of angioplasty compared to medical treatment alone in patients with ARD. The present paper analyzes the most significant studies on renal outcomes in patients with ARD undergoing revascularization or medical treatment alone.

title: Lesão renal aguda como complicação da ingestão excessiva de suco do fruto biri biri (Averrhoa bilimbi)

description: O fruto biri-biri pertence à família das Oxalidacae, espécie Averrhoa bilimbi. Este fruto tem um alto conteúdo de oxalato solúvel e é utilizado na culinária, na produção de picles, geleias, e como tratamento para algumas doenças como hipertensão, diabetes e hiperlipidemia. Assim como outros frutos ricos em oxalato, pode provocar lesão renal aguda. Relatamos o caso de um paciente de 50 anos, hipertenso, com função renal normal, que ingeriu uma grande quantidade de suco em jejum para tratamento de hipertensão. O paciente desenvolveu quadro de lesão renal aguda associado a dores lombares, soluços e diarreia. A lesão renal aguda era não oligúrica e teve uma evolução favorável em 10 dias sem necessidade de tratamento dialítico. A função renal retornou ao normal após esses 10 dias de seguimento.

title: Predictors of acute kidney injury and mortality in an Intensive Care Unit

description: Introduction and Objectives: To compare clinical characteristics and outcomes of patients with and without acute kidney injury (AKI), to evaluate the incidence and mortality of AKI and predictors of AKI and death in patients hospitalized in an Intensive Care Unit (ICU). Methods: A retrospective study analyzed 152 patients admitted to a single ICU. We assessed age, gender, reason for hospitalization, risk factors for ARF, laboratory data, the need for renal therapy substitutive and mortality. Acute Physiology and Chronic Health Evaluation (APACHE II), Sequential Organ Failure Assessment (SOFA) and RIFLE were recorded on the day of ICU admission. We determined the incidence of AKI, mortality and the independent predictors of AKI and death using logistic regression model. Results: Mean age was 57.1 ± 20 years, ranging between 19 to 88 years, and 60.1% were male. Non-dialysis dependent AKI occurred in 81 patients (53.2%) while the ARF requiring dialysis occurred in 19 patients (12.4%). The overall mortality rate in the ICU was 35.9%, whereas the mortality rate in patients with non-dialysis dependent AKI was 43.2% and the IRA with dialysis of 84.2%. In multivariate analysis, invasive mechanical ventilation, elevated creatinine and urea at admission were independent risk factors for AKI, whereas clinical diagnosis, invasive mechanical ventilation, increased lactate and urea and hypernatremia were independent risk factors for ICU mortality. Conclusion: The incidence and mortality of AKI in ICU were high in this study, despite the advances that have been emerging in their management.

title: Gitelman's Syndrome: from diagnosis to follow-up during pregnancy

description: Abstract Gitelman's Syndrome (GS) is a rare autosomal recessive salt-wasting nephropathy, classically characterized by hypokalemia, hypomagnesemia, hypocalciuria, metabolic alkalosis and low blood pressure. Fatigue, muscle weakness and muscle paralysis are common symptoms. Besides the typical electrolyte disturbances, others laboratory findings include hyperreninemia and secondary hyperaldosteronism. Bilateral nephrocalcinosis may occur. The treatment consists of potassium replacement and use of aldosterone antagonists. The best approach to pregnant women with GS is yet to be defined. However, we emphasize the need for ions supplementation, weight control as a clinical tool for assessing the water balance, and frequent monitoring of the fetus and amniotic fluid levels. The surgical risk associated with cesarean section in a patient with GS is not yet defined. Despite the risks related to symptomatic episodes of hypokalemia/hypomagnesemia, GS has a good prognosis when treated properly. Pregnancy imposes the need for more intensive control of the disease, but has a good prognosis for the mother and neonate.

title: Long-term outcomes of elderly kidney transplant recipients

description: Abstract Introduction: The number of elderly patients with chronic kidney disease increases progressively, challenging the allocation algorithms in a scenario of organ shortage for transplantation. Objective: To evaluate the impact of age on patient and graft survival. Methods: Evolution of all 366 patients greater than 60 years transplanted between 1998 and 2010 was analyzed versus a control group of 366 younger patients matched for gender, type of donor (living or deceased) and year of transplantation. Results: Diabetes mellitus (HR 1.8; IC 1.2-2.6; p = 0,003) and prioritization (HR 2.9; IC 1.2-2.6; p &lt; 0,001), but not age, were independent factors for kidney graft loss. Conclusion: Advanced age was not related to negative outcomes after kidney transplantation, after excluding recipient death as a cause of allograft loss. Higher mortality rate in this group was associated to a higher frequency of comorbidities, especially diabetes mellitus.

title: Evaluation of tolerability of enteric-coated mycophenolate sodium versus mycophenolate mofetil in de novo renal transplantation

description: AbstractIntroduction:Mycophenolate mofetil (MMF), pro-drug mycophenolic acid (MPA) is an immunosuppressive effective in the prophylaxis of acute rejection, but associated with gastrointestinal adverse events. Mycophenolate sodium (MPS) with enteric coating was developed with intention of reducing such gastrointestinal adverse events associated with MPA.Objective:To evaluate the tolerability of EC-MPS and MMF in renal transplant recipients.Methods:Retrospective, multicenter study, included 1380 patients who underwent a transplant between 07/01/2004 and 31/07/2007 in 18 Brazilian centers.Results1380 patients enrolled, 702 received EC-MPS and 678 received MMF. The average age of patients was 42.3 years, 60% were male and 62.5% of Caucasian ethnicity. The incidence of events evaluated in the composite endpoint of efficacy was not different between groups at the end of 24 months follow-up (22.9% for EC-MPS to MMF versus19.9%, p = 0.203). Patients treated with EC-MPS had a higher incidence of gastrointestinal adverse events compared to those treated with MMF (57.7%vs. 52.5%), but there was no statistical difference between groups. Viral infections were more frequent in the EC-MPS group (38.2%) compared with MMF (32.6%). There was no difference in mean tolerated dose after the first (1187 ± 344vs. 1209 ± 426 mg, p = 0.294) and second year (1172.3 ± 347 mgvs. 1197.4 ± 430.6 mg, p = 0.241) after transplantation.Conclusion:There was no statistical difference in the incidence of acute rejection, delayed graft function and gastrointestinal events among treatments. The average tolerated dose of MPA was similar between groups; however, patients treated with MMF underwent more dose reductions and discontinuations of treatment.

title: Is energy intake underreported in hemodialysis patients?

description: AbstractIntroduction:Underreporting of energy intake is not much studied in hemodialysis population.Objective:To evaluate the underreporting of energy intake and associated factors in hemodialysis patients.Methods:A cross-sectional study, with 344 patients stable adults, of ten hemodialysis centers in Goiânia-GO. Energy intake was assessed by six 24-hour dietary recalls and basal metabolic rate (BMR) was estimated using the Harris Benedict equation. It was considered as underreporting when the ratio between the average energy intake and basal metabolic rate was lower than1.27. For analysis of factors associated with underreporting, the Poisson regression with robust variance estimation was applied.Results:The prevalence of underreporting was 65.7%, being more significant in individuals who are overweight and in the non dialysis days. The result of the multivariate analysis identified four factors independently associated with the underreporting: being a female (PR = 1.27, CI = 1.10 to 1.46), body mass index ≥ 25 kg/m2 (PR = 1.29, CI = 1.12 to 1.48), three meals or lower/day (PR = 1.31, CI = 1.14 to 1.51) and hemodialysis length lower than 5 years (PR = 1.19CI = 1.01 to 1.40).Conclusion:The population showed a high prevalence of underreporting of energy intake. Being a female, presenting overweight, lower number of meals/day and lower length time on hemodialysis were factors associated with underreporting.

title: Dyadic Relationship and Quality of Life Patients with Chronic Kidney Disease

description: AbstractIintroduction:Chronic Renal insufficiency (CRI) and dialysis treatment lead to a succession of situations for kidney chronic patient, which compromises his aspect, not only physically, and psychologically, with personal, family and social repercussions.Objective:(1) to verify the existence of differences of dyadic adjustment (DA) according to renal replacement treatment (RRT) and (2) verify the existence of differences quality of life (QOL) in accordance with the RRT.Methods:This is a cross-sectional study of a descriptive nature through surveys, exploratory and correlational. The sample consisted of 125 participants. Of these, 31 were to be made RRT by automated peritoneal dialysis (APD) and 94 hemodialysis (HD). Participants were selected from three renal centers: (1) Centro Renal da Prelada (Porto, Portugal), (2) Centrodial (S. João da Madeira, Portugal) and Centro Renal da Misericórdia de Paredes (Paredes, Portugal). The study was carried out for 6 months. The following instruments were applied: Socio-demographic and clinical questionnaire (SDCQ), Dyadic Adjustment Scale (DAS), World Health Organization Quality of Life (WHOQOL-Bref).Results:The results demonstrate the existence of statistically significant differences between the type of RRT and most areas of QOL, as well as the existence of statistically significant differences between the subscales of the DAS evaluated and the type of RRT.Conclusion:The present study demonstrates a greater commitment in terms of QOL of individuals undergoing treatment for HD when compared with those subjected to APD. It turns out, also, that DA is most strongly perceived by patients in APD than with HD.
