ABSTRACT
Introducción: Las infecciones asociadas a diálisis peritoneal constituyen una de las causas de morbimortalidad más importante en estos pacientes y la terapia antimicrobiana empírica y dirigida adecuada es fundamental para mejorar el resultado, por lo que es importante establecer la microbiología local. Objetivo: Revisar la experiencia clínica de cinco años del Hospital Carlos Van Buren de Valparaíso, Chile, describiendo las características clínicas y microbiológicas de los pacientes con episodios de peritonitis asociada a diálisis peritoneal. Metodología De forma retrospectiva se accedió a los registros clínicos de aquellos pacientes mayores de 18 años que presentaron al menos un evento de peritonitis asociada a diálisis peritoneal. Resultados: De un total de 26 episodios, 62% de los pacientes fueron de sexo femenino, con un promedio de edad de 53 años. La principal comorbilidad fue la hipertensión arterial (100%), y el dolor abdominal fue el síntoma más frecuente (85%), con una mortalidad general de 7,7%. En el laboratorio la leucocitosis, la proteína C reactiva (PCR) y la velocidad de hemosedimentación (VHS) fueron los hallazgos más importantes. Predominaron las cocáceas grampositivas (54%), seguido de bacilos gramnegativos no fermentadores y Enterobacterales en igual proporción (11,5% cada grupo). Casos aislados de Candida albicans y Pasteurella canis fueron identificados, y en 15% de los casos el cultivo resultó negativo. Conclusión: Se pudo conocer las características clínicas y microbiológicas locales de esta patología, para así redefinir las directrices de manejo en la institución.
Background: Infections associated with peritoneal dialysis are one of the most important causes of morbidity and mortality in these patients, and adequate empirical and targeted antimicrobial therapy are essential to improve the outcome, so it is important to establish the local microbiology. Aim: To review the clinical experience of 5 years at the Carlos Van Buren Hospital in Valparaíso, Chile, in order to know the clinical and microbiological characteristics of patients with episodes of peritonitis associated with peritoneal dialysis. Methods: Retrospectively, the clinical records of those patients over 18 years of age who presented at least one peritonitis event associated with peritoneal dialysis were accessed. Results: Of a total of 26 episodes, 62% of the patients were female, with a mean age of 53 years. The main comorbidity was arterial hypertension (100%), and abdominal pain was the most frequent symptom (85%), with an overall mortality of 7.7%. In the laboratory parameters, leukocytosis, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were the most important findings. Gram-positive cocci (54%) predominated, followed by Gram-negative non-fermenting and enterobacterial bacilli in the same proportion (11.5% each group). Isolated cases of Candida albicans and Pasteurella canis were identified, and in 15% of the cases the culture was negative. Conclusion: It was possible to know the local clinical and microbiological characteristics of this pathology, in order to redefine management guidelines for our institution.
ABSTRACT
Liver transplantation is the only effective therapy to reduce the high mortality associated with acute liver failure and acute on chronic liver failure (ACLF). Single-pass albumin dialysis (SPAD) is an extracorporeal supportive therapy used as a bridge to liver transplantation or regeneration. We report a 44-year-old man with alcoholic cirrhosis admitted for critical COVID-19 pneumonia that evolves with ACLF. SPAD technique was performed completing six sessions, with a reduction of bilirubin and ammonia levels. He evolved with severe respiratory failure and refractory septic shock, dying. SPAD is a safe and efficient technique aimed to eliminate liver toxins, preventing multiorgan damage interrupting the process known as the "autointoxication hypothesis". It is easy to implement in any critical patient unit and has lower costs than other extracorporeal liver support therapies.

BACKGROUND: Therapeutic Plasma Exchange (TPE) is a procedure in which plasma and harmful macromolecules are separated from the rest of the blood components by centrifugation or filtration through membranes and are replaced with solutions with albumin and/or plasma. AIM: To communicate our experience using TPE by filtration. MATERIAL AND METHODS: Review of records of 655 TPE sessions performed in 102 patients aged 50 ± 18 years (64% women). The requirement of renal replacement therapy (RRT) and seven days and one year mortality were recorded. RESULTS: Forty five percent of patients had hypertension or diabetes. The main indications for TPE were pulmonary-renal syndrome (PRS) (62%) and antibody mediated graft rejection (29%), followed by neurological diseases (36%). Fifteen percent of patients required RRT for one year. Mortality at seven days and one year was 20 and 30%, respectively. Out of the total of deaths associated with kidney diseases, 88% corresponded to PRS and ANCA vasculitis. The main complications were thrombocytopenia in 41%, hypocalcemia in 18%, and hypotension in 16%. CONCLUSIONS: In our experience, TPE by filtration is a safe technique, with mild and preventable complications. Despite this, the reported mortality is high, which reflects the severity of the diseases that motivated the indication for TPE.

Sepsis is one of the leading causes of death in critically ill patients with COVID-19 and blood purification therapies have a role to immunomodulate the excessive inflammatory response and improve clinical results. One of the devices designed for these therapies is the oXiris® filter, allowing to perform renal replacement therapy combined with selective adsorption of endotoxins and cytokines. We report a 55-year-old male with COVID who developed a septic shock secondary to a sepsis caused by Pseudomona aeruginosa, refractory to the usual management. A veno-venous continuous hemofiltration was started using the oXiris® filter for 48 hours. Subsequently, there was an improvement in clinical perfusion parameters and a reduction in inflammatory markers. The patient was discharged from the intensive care one month later.

Renal papillary necrosis is an infrequent cause of hematuria characterized by ischemic necrosis of the renal medulla, especially the papilla. Its most common cause is analgesic abuse. Despite being oligo-symptomatic, in many cases its presence is associated with serious functional sequelae. Imaging, especially computed tomography, is essential to make the diagnosis. We report a 63-year-old female studied for an asymptomatic microscopic hematuria whose tomographic study showed a bilateral renal papillary necrosis. No etiology was found, and she evolved with a spontaneous complete remission.
