RESUMO
INTRODUCTION: For the majority of renal replacement therapy history, the main treatment option for patients with end-stage renal disease (ESRD) in Mexico has been peritoneal dialysis. However, the use of hemodialysis is overwhelmingly increasing, driving public health care institutions to subrogate this service. Even when the actual hiring model for subrogation is accurate, there is a lack of quality control points in the hemodialysis prescription, poor adherence to clinical practice guidelines, and a few or no record of outcomes in hemodialysis patients of these subrogated services. The objective of this work is to fill this information gap to allow for uniform and safe hemodialysis for patients of Mexico. MATERIAL AND METHODS: An observational and cross-sectional study was performed, including all patients receiving chronic hemodialysis treatment in subrogated units of Mexican Social Security Institute (IMSS) in the northern region of Mexico City. Clinical and biochemical data as well as hemodialysis dose by Kt/V and urea reduction rate were collected and evaluated. To determine distribution, mean or median and SD or interquartile range were used; for nominal variables, the difference in proportions was estimated using the χ2 test; proportions were analyzed for biochemical values using the statistical package SPSS version 25. RESULTS: In our study, >60% (485) of the patients were anemic with an average hemoglobin of 9.39 mg/dL (SD ± 1.83); serum calcium was found below 8.4 mg/dL in 51.3% (383) of patients, and only in 45.8% (342) was at an optimal level of this parameter. Only 33.5% of patients have arteriovenous fistula for dialysis access. The hemodialysis dose was optimal in >75% of patients. CONCLUSIONS: It is necessary to enhance and monitor treatment of comorbidities in patients with ESRD in subrogated hemodialysis units in México. We observed adequate prescription of hemodialysis in a majority of patients, achieving quality control points for removal of nitrogen products. Yet, there is a lack of quality control of comorbidities; therefore, we should aim to optimize treatment for mineral-bone disorder, anemia, and nutritional status.

OBJECTIVE: Posttransplant anemia (PTA) in kidney recipients is a complication that has repercussions mainly of cardiovascular consequence. The objective of this study is to determine the prevalence of anemia, as well as the relationship between kidney recipient and donor sex, in the presence or absence of anemia at 12 months after kidney transplant (KT). MATERIAL AND METHODS: Observational, longitudinal study of KTs made over a 5-year period, from 2013 to 2017, in a renal transplant unit from La Raza National Health Care Medical Center. Three hundred twenty-eight records were analyzed. Hemoglobin (Hb) and the presence or absence of anemia according to the definition by the World Health Organization were analyzed. The association between kidney recipient sex and donor type (living or deceased) was evaluated. Analysis of central tendency and dispersion were performed and the mean difference was established with χ2 test or Student t test. Significance level was set at P < .05. RESULTS: The mean Hb (standard deviation) before KT was 10.38 (2.16) g/dL; Hb at 12 months was 14.47 (2.37) g/dL with an absolute increase of 4.09 g/dL. Before KT, male kidney recipients had a mean Hb of 10.54 (2.17) g/dL. At 12 months post-KT, mean Hb was 15.33 (2.25) with a change of 4.79 g/dL. Before KT, female kidney recipients had a mean Hb of 10.16 (2.13) g/dL. At 12 months post-KT, mean Hb was 13.31 (2.01) with a change of 3.15 g/dL. The difference between both sexes was 1.64 g/dL at the end of 12 months. Sixteen out of 152 (10.5%) patients had a serum creatinine (Cr) < 1.2 mg/dL and anemia; 36 out of 176 (20.5%) patients had a Cr ≥ 1.2 mg/dL and anemia (P = .014). In the bivariate logistic regression with an odds ratio of 2.047 (95% confidence interval, 1027-4078; P = .042) for higher Cr levels and the presence of persistent anemia. CONCLUSIONS: There is a prevalence of anemia in female kidney recipients and recipients of kidneys from deceased donors. There is a higher risk of persistent anemia in the case of patients with some degree of graft failure at 12 months.
