ABSTRACT

OBJECTIVE@#To investigate the incidence and risk factors of hypothermia in patients with acute renal injury (AKI) receiving continuous renal replacement therapy (CRRT), and to compare the effects of different heating methods on the incidence of hypothermia in patients with CRRT.@*METHODS@#A prospective study was conducted. AKI patients with CRRT who were admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to December 2022 were enrolled as the study subjects. Patients were divided into dialysate heating group and reverse-piped heating group according to randomized numerical table method. Both groups were provided with reasonable treatment mode and parameter setting by the bedside physician according to the patient's specific condition. The dialysis heating group used the AsahiKASEI dialysis machine heating panel to heat the dialysis solution at 37 centigrade. The reverse-piped heating group used the Barkey blood heater from the Prismaflex CRRT system to heat the dialysis solution, and the heating line temperature was set at 41 centigrade. The patient's temperature was then continuously monitored. Hypothermia was defined as a temperature lower than 36 centigrade or a drop of more than 1 centigrade from the basal body temperature. The incidence and duration of hypothermia were compared between the two groups. Binary multivariate Logistic regression analysis was used to explore the influencing factors of hypothermia during CRRT in AKI patients.@*RESULTS@#A total of 73 patients with AKI treated with CRRT were eventually enrolled, including 37 in the dialysate heating group and 36 in the reverse-piped heating group. The incidence of hypothermia in the dialysis heating group was significantly lower than that in the reverse-piped heating group [40.5% (15/37) vs. 69.4% (25/36), P < 0.05], and the hypothermia occurred later than that in the reverse-piped heating group (hours: 5.40±0.92 vs. 3.35±0.92, P < 0.01). Patients were divided into hypothermic and non-hypothermic groups based on the presence or absence of hypothermia, and a univariate analysis of all indicators showed a significant decrease in mean arterial pressure (MAP) in hypothermic patients (n = 40) compared with the non-hypothermic patients [n = 33; mmHg (1 mmHg ≈ 0.133 kPa): 77.45±12.47 vs. 94.42±14.51, P < 0.01], shock, administration of medium and high doses of vasoactive drug (medium dose: 0.2-0.5 μg×kg-1×min-1, high dose: > 0.5 μg×kg-1×min-1) and CRRT treatment were significantly increased [shock: 45.0% (18/40) vs. 6.1% (2/33), administration of medium and high doses of vasoactive drugs: 82.5% (33/40) vs. 18.2% (6/33), administration of CRRT (mL×kg-1×h-1): 51.50±9.38 vs. 38.42±10.97, all P < 0.05], there were also significant differences in CRRT heating types between the two groups [in the hypothermia group, the main heating method was the infusion line heating, which was 62.5% (25/40), while in the non-hypothermia group, the main heating method was the dialysate heating, which was 66.7% (22/33), P < 0.05]. Including the above indicators in a binary multivariate Logistic regression analysis, it was found that shock [odds ratio (OR) = 17.633, 95% confidence interval (95%CI) was 1.487-209.064], mid-to-high-dose vasoactive drug (OR = 24.320, 95%CI was 3.076-192.294), CRRT heating type (reverse-piped heating; OR = 13.316, 95%CI was 1.485-119.377), and CRRT treatment dose (OR = 1.130, 95%CI was 1.020-1.251) were risk factors for hypothermia during CRRT in AKI patients (all P < 0.05), while MAP was protective factor (OR = 0.922, 95%CI was 0.861-0.987, P < 0.05).@*CONCLUSIONS@#AKI patients have a high incidence of hypothermia during CRRT treatment, and the incidence of hypothermia can be effectively reduced by heating CRRT treatment fluids. Shock, use of medium and high doses of vasoactive drug, CRRT heating type, and CRRT treatment dose are risk factors for hypothermia during CRRT in AKI patients, with MAP is a protective factor.

ABSTRACT

OBJECTIVES@#To study the role of plasma exchange combined with continuous blood purification in the treatment of refractory Kawasaki disease shock syndrome (KDSS).@*METHODS@#A total of 35 children with KDSS who were hospitalized in the Department of Pediatric Intensive Care Unit, Hunan Children's Hospital, from January 2019 to August 2022 were included as subjects. According to whether plasma exchange combined with continuous veno-venous hemofiltration dialysis was performed, they were divided into a purification group with 12 patients and a conventional group with 23 patients. The two groups were compared in terms of clinical data, laboratory markers, and prognosis.@*RESULTS@#Compared with the conventional group, the purification group had significantly shorter time to recovery from shock and length of hospital stay in the pediatric intensive care unit, as well as a significantly lower number of organs involved during the course of the disease (P<0.05). After treatment, the purification group had significant reductions in the levels of interleukin-6, tumor necrosis factor-α, heparin-binding protein, and brain natriuretic peptide (P<0.05), while the conventional group had significant increases in these indices after treatment (P<0.05). After treatment, the children in the purification group tended to have reductions in stroke volume variation, thoracic fluid content, and systemic vascular resistance and an increase in cardiac output over the time of treatment.@*CONCLUSIONS@#Plasma exchange combined with continuous veno-venous hemofiltration dialysis for the treatment of KDSS can alleviate inflammation, maintain fluid balance inside and outside blood vessels, and shorten the course of disease, the duration of shock and the length of hospital stay in the pediatric intensive care unit.

ABSTRACT

Objective: To explore the application effects of bundle nursing of citric acid extracorporeal anticoagulation on continuous renal replacement therapy (CRRT) of severe burn patients. Methods: A non-randomized controlled study was conducted. Forty-six patients who met the inclusion criteria and received regular nursing of citric acid extracorporeal anticoagulation during CRRT in the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from January to December 2017 were included in regular nursing group (30 males and 16 females, aged 42.0 (38.7,47.0) years, with 201 times of CRRT performed), and 48 patients who met the inclusion criteria and received bundle nursing of citric acid extracorporeal anticoagulation during CRRT in the same hospital from January to December 2018 were included in bundle nursing group (32 males and 16 females, aged 41.0 (36.0,46.0) years, with 164 times of CRRT performed). The clinical data of all the patients in the two groups were recorded, including the length of intensive care unit (ICU) stay, total cost of treatment in ICU, cost of CRRT, unplanned ending of treatment, ending of treatment due to operation (with the rates of unplanned ending of treatment and ending of treatment due to operation calculated), times of disposable hemodialysis filter and supporting pipeline filter (hereinafter referred to as filter) with use time>24 h, times of CRRT, and lifetime of filter. For the patients in both groups who continuously received CRRT for 3 days or more from the first treatment, the prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), total calcium, ionic calcium (with the difference of total calcium or ionic calcium between before and after treatment calculated), creatinine, urea, β2 microglobulin, cystatin C, platelet count, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid levels before the first treatment (hereinafter referred to as before treatment) and 3 days after the first treatment (hereinafter referred to as after 3 days of treatment). The treatment-related complications of all patients in the two groups were recorded during hospitalization. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. Results: Compared with those in regular nursing group, the length of ICU stay was significantly shortened (Z=-4.71, P<0.01), the total cost of treatment in ICU was significantly reduced (t=-1.39, P<0.01), the cost of CRRT had no significant change (P>0.05), the rates of unplanned ending of treatment and ending of treatment due to operation were both significantly decreased (with χ2 values of 12.20 and 17.83, respectively, P<0.01), the times of filter service time>24 h was increased significantly (Z=-5.93, P<0.01), the times of CRRT were significantly reduced (Z=-4.75, P<0.01), and the filter service life was significantly prolonged (Z=-9.24, P<0.01) among patients in bundle nursing group. Thirty-one patients in bundle nursing group and 28 patients in regular nursing group continuously received CRRT for 3 days or more from the first treatment. Before treatment, PT, APTT, and INR of patients in bundle nursing group were 24.10 (16.08, 39.20) s, 38.81 (32.32, 45.50) s, and 1.17 (1.12, 1.19), respectively, similar to 31.75 (22.99, 40.96) s, 41.82 (35.05, 48.06) s, and 1.15 (1.11, 1.19) of patients in regular nursing group (P>0.05); the levels of total calcium and ionic calcium of patients in the two groups were similar (P>0.05). After 3 days of treatment, PT, APTT, and INR of patients in bundle nursing group and regular nursing group were 29.06 (20.11, 39.46) s, 35.25 (30.06, 40.28) s, 1.13 (1.09, 1.17) and 36.51 (26.64, 42.92) s, 39.89 (34.81, 46.62) s, 1.14 (1.10, 1.18), respectively, similar to those before treatment (P>0.05); the level of ionic calcium of patients in regular nursing group was significantly higher than that before treatment (Z=-2.08, P<0.05); the levels of total calcium and ionic calcium of patients in bundle nursing group were both significantly higher than those before treatment (with Z values of -3.55 and -3.69, respectively, P<0.01); compared with those in regular nursing group, APTT of patients was significantly shorter (Z=-2.29, P<0.05), while the total calcium level of patients was significantly higher in bundle nursing group (Z=-2.26, P<0.05). The difference of total calcium between before and after treatment of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-3.15, P<0.01). The differences of ionic calcium between before and after treatment of patients in the two groups were similar (P>0.05). Before treatment, the level of β2 microglobulin of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-2.84, P<0.01), the platelet count of patients in bundle nursing group was significantly lower than that in regular nursing group (Z=-2.44, P<0.05), while the levels of creatinine, urea, cystatin C, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid of patients in the two groups were similar (P>0.05). After 3 days of treatment, the levels of creatinine, urea, β2 microglobulin, cystatin C, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -2.10, -2.90, -3.11, -2.02, -2.34, -2.63, and -2.84, respectively, P<0.05 or P<0.01), while the levels of platelet count, oxygenation index, and mean arterial pressure of patients were all significantly higher than those before treatment in bundle nursing group (with Z values of -6.65 and -2.40, respectively, t=-9.97, P<0.05 or P<0.01); the levels of creatinine, urea, β2 microglobulin, cystatin C, platelet count, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -5.32, -2.31, -2.41, -2.21, -3.68, -2.93, -2.20, and -2.31, respectively, P<0.05 or P<0.01), while the oxygenation index and mean arterial pressure of patients were both significantly higher than those before treatment in regular nursing group (Z=-5.59, t=-7.74, P<0.01). After 3 days of treatment, compared with those in regular nursing group, the levels of creatinine, cystatin C, platelet count, oxygenation index, bicarbonate radical, and mean arterial pressure of patients were all significantly higher (with Z values of -2.93, -1.99, -6.39, -2.09, and -2.52, respectively, t=-3.28, P<0.05 or P<0.01), while the levels of urea, β2 microglobulin, pH value, and lactic acid of patients were all significantly lower (with Z values of -3.87, -2.58, -4.24, and -2.75, respectively, P<0.05 or P<0.01) in bundle nursing group. During hospitalization, there were no treatment-related bleeding events or hypernatremia related to citric acid treatment of patients in the two groups. The ratio of total calcium to ionic calcium in one patient in bundle nursing group was >2.5, but there was no manifestation of citric acid accumulation poisoning; 1 patient had hypoionic calcemia, and 1 patient had severe metabolic alkalosis. Five patients had hypoionic calcemia and 2 patients had severe metabolic alkalosis in regular nursing group. Conclusions: The implementation of bundle nursing of citric acid extracorporeal anticoagulation during CRRT for severe burn patients shortens the length of ICU stay, reduces the total cost of treatment in ICU and the occurrence of treatment-related complications, relieves the economic burden of patients, and improves the continuity and quality of treatment.

ABSTRACT

Objective: To investigate the prognosis factors for death within 90 days after discharge in patients with acute kidney injury(AKI) treated requiring continuous renal replacement therapy(CRRT) undergoing surgery for acute Standford type A aortic dissection. Methods: The clinic data of 126 patients undergoing CRRT for postoperative AKI after acute type A aortic dissection surgery in the Center for Cardiac Intensive Care, Beijing Anzhen Hospital from July 2016 to February 2019 were analyzed retrospectively. There were 83 males and 43 females, aging (52.9±11.2) years(range: 25 to 70 years). The patients' demographic characteristics, disease-related information, perioperative data, laboratory indexes during CRRT, complications, and survival information within 90 days after discharge were recorded. Independent prognosis factors for death within 90 days of discharge were determined by Kaplan-Meier survival analysis, univariate and multifactorial Cox regression analysis. Results: Totally 57 of 126 patients(45.2%) died over the first 90 days after discharge. Kaplan-Meier survival analysis and univariate Cox regression analysis showed that there were significant differences between the non-survival and survival group including ≥65 years old, high lactate values 12 hours after CRRT, pulmonary infection, liver dysfunction, presence of permanent neurological complications, and postoperative ejection fraction(EF)<45%. Multifactorial Cox regression analysis revealed that ≥65 years old(HR=2.14, 95%CI: 1.09 to 4.21, P=0.03), high lactate values 12 hours after CRRT(HR=1.13, 95%CI: 1.06 to 1.20, P=0.01) and postoperative EF<45%(HR=2.21, 95%CI: 1.09 to 4.51, P=0.03) were independent prognosis factors for patients' death within 90 days after hospital discharge. Conclusions: ≥65 years old, high lactate values 12 hours after CRRT and postoperative EF<45% are independent prognosis factors for death within 90 days after discharge in patients undergoing CRRT for AKI after acute type A aortic dissection surgery. Proper identification and management of prognosis factors could be beneficial to improve patients' outcomes.

ABSTRACT

OBJECTIVES@#To evaluate the effect of fluid load on the prognosis of children with sepsis-associated acute kidney injury (AKI) undergoing continuous renal replacement therapy (CRRT).@*METHODS@#A total of 121 children who underwent CRRT for sepsis-associated AKI from August 2018 to March 2021 were enrolled in the retrospective study. According to the fluid load from admission or disease progression to CRRT, they were divided into three groups: low fluid load (fluid load: <5%; n=35), high fluid load (fluid load: 5% - <10%; n=35), and fluid overload (fluid load: ≥10%; n=51). Baseline data and clinical biochemical data before CRRT were collected for comparison and analysis. The Kaplan-Meier survival curve analysis was used for comparison of 28-day survival between groups. The multivariate logistic regression model was used to identify the influencing factors for the prognosis of the children.@*RESULTS@#The survival analysis showed that the fluid overload group had a significantly higher 28-day mortality rate than the low fluid load and high fluid load groups (P<0.05). The multivariate logistic regression analysis showed that an increase in fluid overload volume was a risk factor for increased 28-day mortality in the fluid overload group, while earlier initiation of CRRT was a protective factor (P<0.05).@*CONCLUSIONS@#Fluid overload before CRRT may increase the mortality in children with sepsis-associated AKI, and CRRT should be performed for these children as early as possible.

The medical records were reviewed for the variables age, sex, hemofilter duration, duration of therapy, venous access, creatinine and urea values. The IBM SPSS program for Windows was used to calculate absolute frequency distributions, mean, percentages, median, standard deviation, minimum and maximum value. Results: The median age was 73 years, hemofilter had a mean duration of 14.70 hours, mean therapy time 77 hours, mean creatinine values 206.9 µmol /l and urea 22.4 mmol /l. Systemic anticoagulation was used. Conclusions: The nursing involvement was decisive in the successful use of continuous renal replacement therapies in the Surgical Intensive Care Unit studied. Acute renal failure was the cause of initiation of therapies; older patients predominated with no differences in relation to sex. The therapy was kept for more than 72 hours in several patients; a greater longevity of the filters should be achieved(AU)

ABSTRACT

RESUMO Objetivo: Avaliar a incidência de hipotermia em pacientes em terapia renal substitutiva contínua na unidade de terapia intensiva. Como objetivos secundários, determinar fatores associados e comparar a ocorrência de hipotermia entre duas modalidades de terapia renal substitutiva contínua. Métodos: Estudo de coorte, prospectivo, realizado com pacientes adultos internados em uma unidade de terapia intensiva clínico-cirúrgica, que realizaram terapia renal substitutiva contínua em um hospital universitário público de alta complexidade do Sul do Brasil, de abril de 2017 a julho de 2018. A hipotermia foi definida como queda da temperatura corporal ≤ 35ºC. Os pacientes incluídos no estudo foram acompanhados nas 48 horas iniciais de terapia renal substitutiva contínua. Os dados foram coletados pelos pesquisadores por meio da consulta aos prontuários e às fichas de registro das terapias renais substitutivas contínuas. Resultados: Foram avaliados 186 pacientes distribuídos igualmente entre dois tipos de terapia renal substitutiva contínua: hemodiálise e hemodiafiltração. A incidência de hipotermia foi de 52,7%, sendo maior nos pacientes que internaram por choque (risco relativo de 2,11; IC95% 1,21 - 3,69; p = 0,009) e nos que fizeram hemodiafiltração com aquecimento por mangueira na linha de retorno (risco relativo de 1,50; IC95% 1,13 - 1,99; p = 0,005). Conclusão: A hipotermia em pacientes críticos com terapia renal substitutiva contínua é frequente, e a equipe intensivista deve estar atenta, em especial quando há fatores de risco associados.


ABSTRACT Objective: To evaluate the incidence of hypothermia in patients undergoing continuous renal replacement therapy in the intensive care unit. As secondary objectives, we determined associated factors and compared the occurrence of hypothermia between two modalities of continuous renal replacement therapy. Methods: A prospective cohort study was conducted with adult patients who were admitted to a clinical-surgical intensive care unit and underwent continuous renal replacement therapy in a high-complexity public university hospital in southern Brazil from April 2017 to July 2018. Hypothermia was defined as a body temperature ≤ 35ºC. The patients included in the study were followed for the first 48 hours of continuous renal replacement therapy. The researchers collected data from medical records and continuous renal replacement therapy records. Results: A total of 186 patients were equally distributed between two types of continuous renal replacement therapy: hemodialysis and hemodiafiltration. The incidence of hypothermia was 52.7% and was higher in patients admitted for shock (relative risk of 2.11; 95%CI 1.21 - 3.69; p = 0.009) and in those who underwent hemodiafiltration with heating in the return line (relative risk of 1.50; 95%CI 1.13 - 1.99; p = 0.005). Conclusion: Hypothermia in critically ill patients with continuous renal replacement therapy is frequent, and the intensive care team should be attentive, especially when there are associated risk factors.

ABSTRACT

La injuria renal aguda (IRA) se caracteriza por un abrupto deterioro de la función renal asociado a lteraciones hidroelectrolíticas y metabólicas. La misma es frecuente en la unidad de cuidados intensivos (UCI) pediátricos y tiene un impacto significativo en la morbilidad y mortalidad. Las principales indicaciones de terapia de reemplazo renal (TRR) incluyen la corrección de los trastornos metabólicos y el manejo de la sobrecarga de fluidos. Varios modos de TRR pueden ser utilizadas en la UCI: hemodiálisis intermitente, diálisis peritoneal y las terapias de reemplazo renal continuas (TRRC). Las terapias de reemplazo renal continuas han ganado un rol preponderante en Cuidados Críticos ya que posibilitan dializar a pacientes hemodinámicamente inestables. Del total de pacientes admitidos en la UCI (n:1506) desde enero 2012 hasta diciembre 2018, requirieron TRRC el 6,7% (n: 102). La mortalidad predicha por el Score PIM3 fue de 19,53%, la mediana de edad en meses fue de 60 (RIC 25-75: 12-144), no hubo diferencias en cuanto al sexo. Los diagnósticos más frecuentes fueron trasplantados de órganos sólidos 33%, seguidos de trasplante de células progenitoras hematopoyéticas (TCPH) el 26%. La mediana de los días de internación fue de 16 (RIC 25-75: 7-29) y de días de requerimiento de una TRRC 5 (RIC 25-75 3-9). La técnica dialítica más utilizada fue CVVHD, en el 87% de los pacientes. La mortalidad global fue del 75%, presentando los pacientes con TCPH mayor mortalidad con respecto a otros diagnósticos. Se debe reconocer y categorizar precozmente a los pacientes con mayor riesgo de desarrollar IRA y aplicar medidas de nefroprotección para mejorar su sobrevida (AU)


Acute renal injury (IRA) is characterized by sudden deterioration of kidney function associated with hydroelectrolytic and metabolic disturbances. IRA is common in the pediatric intensive care unit (ICU) and has a significant impact on morbidity and mortality. The main indications for renal replacement therapy (RRT) include correction of the metabolic disorders and management of fluid overload. Different types of RRT may be used in the ICU: intermittent hemodialysis, peritoneal dialysis, and continuous renal replacement therapies (CRRT). Continuous renal replacement therapies have gained a major role in critical care as they allow for dialysis in hemodynamically unstable patients. Of all patients admitted to the ICU (n:1506) between January 2012 and December 2018, 6.7% required CRRT (n: 102). Predicted mortality rate according to the PIM3 score was 19.53%. Median age was 60 months (IQR 25-75: 12-144). No differences in sex were observed. The most common diagnoses were solid organ transplantation in 33%, followed by hematopoietic stem cell transplantation (HSCT) in 26%. Median length of hospital stay was 16 days (IQR 25-75: 7-29) and median days on CTTT was 5 (IQR 25-75 3-9). The most common dialysis technique was CVVHD, used in 87% of the patients. Overall mortality rate was 75%, with a higher mortality in HSCT patients compared to others. Patients at a higher risk of developing IRA should be timely recognized and categorized and nephroprotective measures should be started early to improve survival (AU)

ABSTRACT

Abstract Introduction: Sodium fluoroacetate, known as compound 1080, was discovered in Germany during the Second World War. It is usually used as a rodenticide, it is an odorless and tasteless substance, with a lethal dose in humans of 2 mg / kg that is why it was withdrawn from the market in some countries, including Colombia; however, it is obtained illegally. This substance has biochemical and physiological effects at the cellular level that alter the transport of citrate at the mitochondrial level, generating accumulation of lactic acid and alteration of the glucose use. The clinical manifestations are nonspecific since there is no any cardinal symptom. Therefore, its diagnosis is made due to high clinical suspicion associated with establishment of exposure to the compound in view of the difficulty to obtain paraclinical confirmation in a timely manner. Methods: We present a case report of intentional ingestion of sodium fluoroacetate in an adolescent that is associated with an infection added to the bloodstream by methicillin- sensitive Staphylococcus aureus (MSSA). The patient developed multiple complications that lead to support in the Intensive Care Unit (ICU) with a satisfactory outcome. In view of the lack of a specific antidote, she was treated with ethanol in order to increase the level of acetate; thus, offering an alternative substrate to the Krebs cycle. It is suggested that the ethanol offers benefits in the acute treatment of these patients. Results: The patient with sodium fluoroacetate poisoning and kidney failure received renal replacement therapy with a favorable evolution and survival at discharge from the intensive care unit of a third-level hospital in the city of Pereira, Risaralda, Colombia. Conclusions: Sodium fluoroacetate poisoning is relatively rare and can cause acute kidney injury and multi-organ failure with a high rate of complications and death. A case of self-inflicted poisoning that received a timely manner continuous renal replacement therapy with a favorable outcome in terms of ICU survival was presented.


Resumen Introducción: El fluoroacetato de sodio ⎯conocido como compuesto 1080⎯, fue descubierto en Alemania durante la segunda guerra mundial, suele ser utilizado como raticida y se caracteriza por ser una sustancia inodora e insabora. En humanos, una dosis de 2 a mg/kg es letal; debido a su toxicidad fue retirado del mercado en algunos países, incluyendo Colombia, no obstante, se consigue de forma ilegal. Esta sustancia tiene efectos bioquímicos y fisiológicos a nivel celular que altera el transporte del citrato a nivel mitocondrial, generando acumulación de ácido láctico y alteración en la utilización de la glucosa. Las manifestaciones clínicas son inespecíficas y no existe un síntoma cardinal. Por ende, su diagnóstico se realiza por alta sospecha clínica, asociado al establecimiento de la exposición al compuesto, ya que la confirmación paraclínica es difícil de realizar oportunamente. Métodos: Se presenta un reporte de caso de ingestión intencional en un adolescente, asociado con infección agregada al torrente sanguíneo por Estafilococos Aureos Meticilino Sensible (EAMS). El paciente desarrolló múltiples complicaciones y requirió asistencia en Unidad de Cuidados Intensivos (UCI) con desenlace satisfactorio. Ya que no se cuenta con antídoto específico , se le dio tratamiento con etanol para aumentar el nivel de acetato, ofreciendo así un sustrato alterno al ciclo de Krebm. Se estima que el etanol puede ofrecer beneficios en el tratamiento agudo de estos pacientes. Resultados: Paciente con intoxicación por fluoroacetato de sodio e insuficiencia renal, recibe terapia de reemplazo renal con un evolución favorable y supervivencia al alta de la Unidad de Cuidados Intensivos de un hospital de tercer nivel en la ciudad de Pereira, Risaralda, Colombia. Conclusiones: La intoxicación por fluoroacetato de sodio es relativamente poco frecuente y puede causar injuria renal aguda y falla multiorgánica con alta tasa de complicaciones y muerte. Se presentó un caso de intoxicación autoinfligida que recibió terapia de reemplazo renal continua temprana con un desenlace favorable en términos de supervivencia en la UCI.

ABSTRACT

La linfohistiocitosis hemofagocítica (LHH) puede ser primaria (hereditaria) o secundaria a infecciones, tumores malignos, trastornos reumatológicos, síndromes de inmunodeficiencia y metabolopatías. Se informaron casos de intolerancia a la proteína lisinúrica, deficiencia de múltiples sulfatasas, galactosemia, enfermedad de Gaucher, síndrome de Pearson y galactosialidosis. No se sabe cómo se desencadena la LHH en las metabolopatías. Se diagnosticó LHH en un lactante de 2 meses con letargo, palidez, alimentación deficiente, hepatoesplenomegalia, fiebre y pancitopenia, y se instauró el protocolo HLH-2004. Se realizaron, en conjunto, análisis para detectar mutaciones genéticas y pruebas metabólicas; los resultados fueron negativos para las mutaciones genéticas de LHH primaria, pero se detectaron hiperamoniemia y concentración elevada de metilcitrato. Se diagnosticó acidemia propiónica. Aquí informamos sobre un caso de LHH secundaria a acidemia propiónica. Es posible la realización simultánea de pruebas de detección de trastornos metabólicos y de mutaciones genéticas para el diagnóstico temprano en los lactantes con LHH


Hemophagocytic lymphohystiocytosis (HLH) may be primary (inherited/familial) or secondary to infections, malignancies, rheumatologic disorders, immune deficiency syndromes and metabolic diseases. Cases including lysinuric protein intolerance, multiple sulfatase deficiency, galactosemia, Gaucher disease, Pearson syndrome, and galactosialidosis have previously been reported. It is unclear how the metabolites trigger HLH in metabolic diseases. A 2-month-old infant with lethargy, pallor, poor feeding, hepatosplenomegaly, fever and pancytopenia, was diagnosed with HLH and the HLH-2004 treatment protocol was initiated. Analysis for primary HLH gene mutations and metabolic screening tests were performed together; primary HLH gene mutations were negative, but hyperammonemia and elevated methyl citrate were detected. Propionic acidemia was diagnosed with tandem mass spectrometry in neonatal dried blood spot. We report this case of HLH secondary to propionic acidemia. Both metabolic disorder screening tests and gene mutation analysis may be performed simultaneously especially for early diagnosis in infants presenting with HLH.

ABSTRACT

RESUMEN En los últimos años, y debido en parte a los avances tecnológicos, ha resurgido el uso de los sistemas de depuración extracorpórea de dióxido de carbono de manera pareja al uso de la oxigenación con membrana extracorpórea. No obstante, faltan estudios para establecer sus indicaciones y el nivel de evidencia para su uso. Estos sistemas permiten eliminar el dióxido de carbono de manera eficaz en pacientes con insuficiencia respiratoria hipercápnica con catéteres de pequeño calibre, habitualmente de doble luz y con pequeña superficie de membrana depuradora. En la actualidad disponemos de varios tipos de sistemas, con distinta versatilidad y tamaño de membrana. Los sistemas veno-venosos con bomba producen menos complicaciones que los arterio-venosos. Ambos precisan anticoagulación sistémica. El soporte "pulmón-riñón" mediante la combinación de un sistema depurador con un hemofiltro permitiría al mismo tiempo eliminar dióxido de carbono y realizar depuración extrarrenal continua. Describimos nuestra experiencia inicial con un sistema combinado de depuración extracorpórea de dióxido de carbono-depuración extrarrenal continua en un paciente con trasplante de pulmón, insuficiencia respiratoria hipercápnica, barotrauma y fallo renal agudo asociado. Se describen los aspectos técnicos más importantes, la efectividad del sistema para la eliminación de dióxido de carbono y se realiza una revisión de la literatura.


ABSTRACT In recent years and due, in part, to technological advances, the use of extracorporeal carbon dioxide removal systems paired with the use of extracorporeal membrane oxygenation has resurfaced. However, studies are lacking that establish its indications and evidence to support its use. These systems efficiently eliminate carbon dioxide in patients with hypercapnic respiratory failure using small-bore cannula, usually double-lumen cannula with a small membrane lung surface area. Currently, we have several systems with different types of membranes and sizes. Pump-driven veno-venous systems generate fewer complications than do arteriovenous systems. Both require systemic anticoagulation. The "lung-kidney" support system, by combining a removal system with hemofiltration, simultaneously eliminates carbon dioxide and performs continuous extrarenal replacement. We describe our initial experience with a combined system for extracorporeal carbon dioxide removal-continuous extrarenal replacement in a lung transplant patients with hypercapnic respiratory failure, barotrauma and associated acute renal failure. The most important technical aspects, the effectiveness of the system for the elimination of carbon dioxide and a review of the literature are described.

ABSTRACT

Renal replacement therapy (RRT) is a crucial form of extracorporeal support in critical patients that develop acute kidney injury. This therapy allows to gain solute and water control when the kidneys are not capable of doing it. Nevertheless, RRT techniques are not without risks, complications and costs. Under this point of view, is fundamental to be conscious of the indications of timing and, most importantly, weaning of the RRT. The unnecesary extension of these techniques can lead to increase morbidity, hospital stay, health care costs and complications. Unfortunately, randomized controlled studies are scarce and this paucity of data has lead to different predictive models based on retrospective studies. Creatinine clearence, urinary output and other novel biomarkers has been used to identify the best moment to safely stop RRT. In this review, we summarize the available evidence about secure weaning of RRT and the potential of novel urinary and serum biomarkers that can be used to guide therapeutic decisions in the future.

ABSTRACT

RESUMO A segurança e a eficácia do rituximabe em pacientes com comprometimento renal não foram estabelecidas, e o mesmo ocorre com os efeitos da hemodiálise nos níveis séricos de rituximabe. Atualmente, apenas alguns relatos de caso avaliaram o nível sérico de rituximabe antes e após a diálise. Não foram até aqui publicados dados relativos ao uso de rituximabe em pacientes sob terapia de substituição renal contínua. Os autores apresentam um caso referente a uma mulher com 59 anos de idade atendida com quadro de tetraparesia paraneoplásica. Ela foi admitida no serviço de medicina intensiva devido a hemorragia alveolar com insuficiência respiratória e lesão renal aguda, que necessitou da utilização de terapia de substituição renal contínua. Após os procedimentos diagnósticos, estabeleceu-se o diagnóstico de linfoma linfoplasmocítico. Deu-se início ao tratamento com rituximabe e ciclofosfamida. Os níveis de rituximabe foram determinados no soro e no dialisato. Não se encontrou qualquer nível de rituximabe no dialisato. A paciente faleceu após 2 meses no serviço de medicina intensiva por pneumonia nosocomial causada por Pseudomonas aeruginosa resistente a múltiplos fármacos.


ABSTRACT Rituximab safety and efficacy in patients with renal impairment have not been established, nor have the effects of hemodialysis on serum rituximab level. There are only a few published case reports assessing serum rituximab level pre- and postdialysis. No data have been published regarding the usage of rituximab in patients with continuous renal replacement therapy. The authors present a case of a 59-year-old female patient who presented with paraneoplastic tetraparesis. She was admitted to the intensive care unit due to alveolar hemorrhage with respiratory failure and acute kidney injury requiring continuous renal replacement therapy. After a diagnostic workup, the diagnosis of lymphoplasmacytic lymphoma was established. Therapy with rituximab and cyclophosphamide was started. Rituximab levels were determined in serum and dialysate. No rituximab was found in the dialysate. The patient died after 2 months in the intensive care unit from nosocomial pneumonia due to multidrug-resistant Pseudomonas aeruginosa.

ABSTRACT

Reportamos el caso de un hombre de 74 años de edad padeciendo una enfermedad renal terminal, actualmente en terapia de reemplazo crónica, tomando warfarina en dosis regulares, quien presentó síntomas de debilidad y dolor agudo en el flanco derecho durante una sesión de diálisis. Fue enviado al Departamento de Emergencias donde una tomografía computada abdominal con administración intravenosa de contraste reveló la presencia de un amplio hematoma que se desarrollaba en el riñón derecho, con extensión continua al tejido graso perirrenal, fascia de Gerota y al espacio pararrenal posterior. Brindándosele monitoreo hemodinámico y estabilidad imagenológica seriada, el paciente se sometió a tratamiento conservador con reposo en cama, administración de antibióticos y terapia de reemplazo de sangre. La warfarina se interrumpió inmediatamente. No fue requerido ningún procedimiento quirúrgico. Posteriormente a la consulta con hematólogos, se sugirió el reemplazo a largo término de la warfarina por heparina cálcica. La hemorragia retroperitoneal espontánea, de origen ya sea renal o de otras estructuras sangrantes, es un evento relativamente raro, aunque potencial amenaza para la vida. Puede deberse a varias condiciones subyacentes. Entre ellas, el paciente que estamos reportando estaba padeciendo una enfermedad renal quística adquirida y estaba tanto en diálisis a largo plazo como en terapia anticoagulante oral. En el caso de hemorragia renal con condiciones hemodinámicas estables y sin otros elementos sospechosos, el tratamiento conservador debe ser tomado en consideración.


We report the case of a 74-year-old man afflicted with end-stage renal disease, currently in chronic repla wea cement therapy, taking warfarin on a regular basis, who presented feelings of kness and acute right flank pain during a dialysis session. He was sent to the Emergency Department where an abdominal computed tomography with intravenous contrast administration revealed the presence of a wide hematoma developing in the right kidney, with continuous extension to perirenal fat tissue, Gerota's fascia and posterior pararenal space. Given hemodynamic monitoring and serial imaging stability, the patient underwent conservative management with bed rest, antibiotic administration and blood replacement therapy. Warfarin was immediately interrupted. No operative treatment was required. After a consultation with hematologists, long term replace ment of warfarin by heparin calcium was suggested. Spontaneous retroperitoneal hemorrhage , related to either renal or other structures bleeding , is a relatively rare event, though potentially life-threatening . It can be due to several undelying conditions. Among them, the patient we are reporting about was afflicted with acquired cystic kidney disease and he was on both long-term dialysis and oral anticoagulant therapy. In the case of renal hemorrhage with stable hemodynamic conditions and no further suspicious elements, conservative management should be considered.

ABSTRACT

Novel coronavirus 2019 (COVID-19) is a severe respiratory infection leading to acute respiratory distress syndrome [ARDS] accounting for thousands of cases and deaths across the world. Several alternatives in treatment options have been assessed and used in this patient population. However, when mechanical ventilation and prone positioning are unsuccessful, venovenous extracorporeal membrane oxygenation [VV-ECMO] may be used. We present a case of a 62-year-old female, diabetic, admitted to the intensive care unit with fever, flu-like symptoms and a positive COVID-19 test. Ultimately, she worsened on mechanical ventilation and prone positioning and required VV-ECMO. The use of VV-ECMO in COVID-19 infected patients is still controversial. While some studies have shown a high mortality rate despite aggressive treatment, such as in our case, the lack of large sample size studies and treatment alternatives places healthcare providers against a wall without options in patients with severe refractory ARDS due to COVID-19
