Prognosis Factors of Patients Undergoing Renal Replacement Therapy.

BACKGROUND: Survival in patients with end-stage kidney disease (ESKD) on renal replacement therapy (RRT) is less than that of the general population of the same age, and depends on patient factors, the medical care received, and the type of RRT used. The objective of this study is to analyze the factors associated with survival in patients undergoing RRT. METHODS: We conducted a retrospective observational study of adult patients with an incident of ESKD on RRT in Andalusia from 1 January 2008 to 31 December 2018. Patient characteristics, nephrological care received, and survival from the beginning of RRT were evaluated. A survival model for the patient was developed according to the variables studied. RESULTS: A total of 11,551 patients were included. Median survival was 6.8 years (95% CI (6.6; 7.0)). After starting RRT, survival at one year and five years was 88.7% (95% CI (88.1; 89.3)) and 59.4% (95% CI (58.4; 60.4)), respectively. Age, initial comorbidity, diabetic nephropathy, and a venous catheter were independent risk factors. However, non-urgent initiation of RRT and follow-up in consultations for more than six months had a protective effect. It was identified that renal transplantation (RT) was the most influential independent factor in patient survival, with a risk ratio of 0.13 (95% CI (0.11; 0.14)). CONCLUSIONS: The receiving of a kidney transplant was the most beneficial modifiable factor in the survival of incident patients on RRT. We consider that the mortality of the renal replacement treatment should be adjusted, taking into account both modifiable and nonmodifiable factors to achieve a more precise and comparable interpretation.

Desinfección térmica en hemodiálisis usando el concepto A0 como dosificador / Thermal disinfection in hemodialysis using the A0 concept as dispenser

Los pacientes con enfermedad renal crónica en programa de hemodiálisis se encuentran expuestos a grandes cantidades de agua, ya que esta constituye cerca del 96% del líquido de diálisis. Es conocido que el uso de agua de mejor calidad disminuye el estado de inflamación crónica en los pacientes en diálisis. La desinfección como parte del tratamiento del agua tiene un papel importante para cumplir los estándares de calidad establecidos. En la actualidad, la desinfección por calor es muy recomendable, sin embargo, la dosis no está claramente establecida en la bibliografía. El objetivo de esta revisión es conocer los datos disponibles sobre la dosis de desinfección por calor que se debe utilizar en hemodiálisis, así como presentar nuestra experiencia con este método a una dosis establecida de 12.000 A0

Patients with chronic kidney disease in the hemodialysis program are exposed to large amounts of water, as this constitutes about 96% of the dialysis fluid. It is known that the use of better quality water decreases the state of chronic inflammation in dialysis patients. Disinfection as part of water treatment plays an important role in meeting the established quality standards; currently, heat disinfection is highly recommended, however its dose is not clearly established in the literature. The objective of this review is to know what is available in the literature on the dose of heat disinfection that should be used in hemodialysis and to present our experience with this method at a set dose of 12.000 A0

Gentamicin as Empirical Treatment in Hemodialysis Patients: Safety, Pharmacokinetics, and Pharmacodynamics.

The aim of this study was to describe the safety profile and pharmacokinetic/pharmacodynamic parameters in end-stage renal disease patients who received gentamicin as empirical treatment in catheter-related bacteremia when they showed infection signs, regardless of the timing of the next HD. Patients received gentamicin 3 mg/kg before blood culture extraction when they showed infection signs and regardless of the timing of next hemodialysis session. Serum concentrations were collected after the gentamicin administration (peak level) and before the next HD (trough level). Toxicities and adverse drug events were registered. The main pharmacokinetic/pharmacodynamic goal for Gram-negative infections was peak:minimum inhibitory concentration (MIC) ≥10. Sixteen patients were included. Nephrotoxicity was not assessed in this population, and no ototoxicity was found. According to microbial isolation and gentamicin susceptibility, the value of peak:MIC was 5.4 ± 2.0. The administration of gentamicin in these conditions was safe. Estimated pharmacokinetic values were consistent with previous studies and appropriate according to peak:MIC goal for Gram-negative organisms with MIC ≤1 mg/L.
