Unplanned Transfers From Intermediate Care Units to Intensive Care Units: A Cohort Study.

This study evaluated unplanned transfers from the intermediate care unit (IMCU) to the intensive care unit (ICU) among urgent admissions. This retrospective, observational study was conducted in 2 ICUs and 1 IMCU. Three patterns of urgent admission were assessed: admissions to the ICU only, admissions to the IMCU only, and admissions to the IMCU with subsequent transfer to the ICU. Of 5296 admissions analyzed, 1396 patients (26.4%) were initially admitted to the IMCU. Of these, 172 (12.3%) were transferred from the IMCU to the ICU. Mortality was higher in patients transferred from the IMCU to the ICU than in the 3900 ICU-only patients (odds ratio, 3.22; 95% CI, 1.52-6.80). Most transfers from the IMCU to the ICU (135; 78.5%) were due to deterioration of the condition for which the patient was admitted. Patient transfers from the IMCU to the ICU were common, were associated with increased hospital mortality, and were mostly due to deterioration in the condition that was the reason for admission.

Realistic simulation is associated with healthcare professionals' increased self-perception of confidence in providing acute stroke care: a before-after controlled study.

BACKGROUND: Simulations are becoming widely used in medical education, but there is little evidence of their effectiveness on neurocritical care. Because acute stroke is a neurological emergency demanding prompt attention, it is a promising candidate for simulation training. OBJECTIVE: To assess the impact of a stroke realistic simulation course on clinicians' self-perception of confidence in the management of acute stroke. METHODS: We conducted a controlled, before-after study. For our intervention, 17 healthcare professionals participated in a stroke realistic simulation course. As controls, participants were chosen from a convenience sample of attendees to the courses Emergency Neurologic Life Support (ENLS) (18 participants) and Neurosonology (20 participants). All participants responded pre- and post-test questionnaires evaluating their self-perception of confidence in acute stroke care, ranging from 10 to 50 points. We evaluated the variation between pre- and post-test results to assess the change on trainees' self-perception of confidence in the management of acute stroke. Multivariate analysis was performed to control for potential confounders. RESULTS: Forty-six (83.63%) subjects completed both questionnaires. The post-test scores were higher than those from the pretests in the stroke realistic simulation course group [pretest median (interquartile range - IQR): 41.5 (36.7-46.5) and post-test median (IQR): 47 (44.7-48); p=0.033], but not in the neurosonology [pretest median (IQR): 46 (44-47) and post-test median (IQR): 46 (44-47); p=0.739] or the ENLS [pretest median (IQR): 46.5 (39-48.2), post-test median (IQR): 47 (40.2-49); p=0.317] groups. Results were maintained after adjustment for covariates. CONCLUSIONS: This stroke realistic simulation course was associated with an improvement on trainees' self-perception of confidence in providing acute stroke care.

Is there a place for mesenchymal stromal cell-based therapies in the therapeutic armamentarium against COVID-19?

The COVID-19 pandemic, caused by the rapid global spread of the novel coronavirus (SARS-CoV-2), has caused healthcare systems to collapse and led to hundreds of thousands of deaths. The clinical spectrum of COVID-19 is not only limited to local pneumonia but also represents multiple organ involvement, with potential for systemic complications. One year after the pandemic, pathophysiological knowledge has evolved, and many therapeutic advances have occurred, but mortality rates are still elevated in severe/critical COVID-19 cases. Mesenchymal stromal cells (MSCs) can exert immunomodulatory, antiviral, and pro-regenerative paracrine/endocrine actions and are therefore promising candidates for MSC-based therapies. In this review, we discuss the rationale for MSC-based therapies based on currently available preclinical and clinical evidence of safety, potential efficacy, and mechanisms of action. Finally, we present a critical analysis of the risks, limitations, challenges, and opportunities that place MSC-based products as a therapeutic strategy that may complement the current arsenal against COVID-19 and reduce the pandemic's unmet medical needs.

Immunomodulatory and Anti-fibrotic Effects Following the Infusion of Umbilical Cord Mesenchymal Stromal Cells in a Critically Ill Patient With COVID-19 Presenting Lung Fibrosis: A Case Report.

Background: The patients with coronavirus disease 2019 (COVID-19) associated with severe acute respiratory distress syndrome (ARDS) may require prolonged mechanical ventilation which often results in lung fibrosis, thus worsening the prognosis and increasing fatality rates. A mesenchymal stromal cell (MSC) therapy may decrease lung inflammation and accelerate recovery in COVID-19. In this context, some studies have reported the effects of MSC therapy for patients not requiring invasive ventilation or during the first hours of tracheal intubation. However, this is the first case report presenting the reduction of not only lung inflammation but also lung fibrosis in a critically ill long-term mechanically ventilated patient with COVID-19. Case Presentation: This is a case report of a 30-year-old male patient with COVID-19 under invasive mechanical ventilation for 14 days in the intensive care unit (ICU), who presented progressive clinical deterioration associated with lung fibrosis. The symptoms onset was 35 days before MSC therapy. The patient was treated with allogenic human umbilical-cord derived MSCs [5 × 107 (2 doses 2 days interval)]. No serious adverse events were observed during and after MSC administration. After MSC therapy, PaO2/FiO2 ratio increased, the need for vasoactive drugs reduced, chest CT scan imaging, which initially showed signs of bilateral and peripheral ground-glass, as well as consolidation and fibrosis, improved, and the systemic mediators associated with inflammation decreased. Modulation of the different cell populations in peripheral blood was also observed, such as a reduction in inflammatory monocytes and an increase in the frequency of patrolling monocytes, CD4+ lymphocytes, and type 2 classical dendritic cells (cDC2). The patient was discharged 13 days after the cell therapy. Conclusions: Mesenchymal stromal cell therapy may be a promising option in critically ill patients with COVID-19 presenting both severe lung inflammation and fibrosis. Further clinical trials could better assess the efficacy of MSC therapy in critically ill patients with COVID-19 with lung fibrosis associated with long-term mechanical ventilation.

Prognostic ability of quick-SOFA across different age groups of patients with suspected infection outside the intensive care unit: A cohort study.

OBJECTIVES: Sepsis identification in older patients is challenging. We evaluated the performance of qSOFA across different age groups of patients with suspected infection outside the intensive care unit (ICU). METHODS: Retrospective cohort in a tertiary hospital in Brazil, from January 2016 to December 2016. Outcomes were hospital mortality, ICU admission and bacteremia. Performance of qSOFA was compared over three age groups: (1) reference: ≤65 years, (2) old: 65 to 79 years and (3) very old: ≥80 years. RESULTS: There were 420 patients in the study, of which 259 (61.7%) were ≤65 years, 80 (19%) were 65 to 79 years and 81 (19.3%) were ≥80 years. Old and very old patients had higher qSOFA scores and lower SIRS scores. Overall, qSOFA ≥2 was associated to hospital mortality [OR (95% CI) = 5.8 (3.3-10.4), p < 0.001], ICU admission [OR (95% CI) = 2.7 (1.6-4.6), p < 0.001] and bacteremia [OR (95% CI) = 3.1 (1.7-5.8), p < 0.001]. Those associations were stronger in old and very old patients. qSOFA and SIRS demonstrated overall AUROCs for hospital mortality of 0.72 and 0.50, respectively. CONCLUSION: qSOFA demonstrated good overall accuracy and was more strongly associated to outcomes in old and very old patients, when compared to younger patients.

How Can We Estimate Sepsis Incidence and Mortality?

Sepsis is one of the oldest and complex syndromes in medicine that has been in debate for over two millennia. Valid and comparable data on the population burden of sepsis constitute an essential resource for guiding health policy and resource allocation. Despite current epidemiological data suggesting that the global burden of sepsis is huge, the knowledge of its incidence, prevalence, mortality, and case-fatality rates is subject to several flaws. The objective of this narrative review is to assess how sepsis incidence and mortality can be estimated, providing examples on how it has been done so far in medical literature and discussing its possible biases. Results of recent studies suggest that sepsis incidence rates are increasing consistently during the last decades. Although estimates might be biased, this probably reflects a real increase in incidence over time. Nevertheless, case fatality rates have decreased, which is a probable reflex of advances in critical care provision to this very sick population at high risk of death. This conclusion can only be drawn with a reasonable degree of certainty for high-income countries. Conversely, adequately designed studies from middle- and low-income countries are urgently needed. In these countries, sepsis incidence and case-fatality rates could be disproportionally higher due to health care provision constraints and ineffective preventive measures.

Heart conduction system defects and sustained ventricular tachycardia complications in a patient with granulomatosis with polyangiitis. A case report and literature review. / Distúrbios de condução cardíaca e taquicardia ventricular como complicação da granulomatose com poliangiíte em uma paciente. Relato de caso e revisão da literatura.

Granulomatosis with polyangiitis is a rare systemic inflammatory disorder characterized by vasculitis of the small arteries, the arterioles and the capillaries together with necrotizing granulomatous lesions. This case reports on a young female patient, previously diagnosed with granulomatosis with polyangiitis, who was admitted to the intensive care unit with seizures and hemodynamic instability due to a complete atrioventricular heart block. The event was associated with multiple episodes of sustained ventricular tachycardia without any structural heart changes or electrolyte disturbances. In the intensive care unit, the patient was fitted with a provisory pacemaker, followed by immunosuppression with corticosteroids and immunobiological therapy, resulting in a total hemodynamic improvement. Severe conduction disorders in patients presenting granulomatosis with polyangiitis are rare but can contribute to increased morbidity. Early detection and specific intervention can prevent unfavorable outcomes, specifically in the intensive care unit.

A granulomatose com poliangiíte é um raro distúrbio inflamatório sistêmico que se caracteriza por vasculite de pequenas artérias, arteríolas e capilares, associada a lesões granulomatosas necrotizantes. Este artigo relata o caso de uma paciente com diagnóstico prévio de granulomatose com poliangiíte, admitida à unidade de terapia intensiva com quadro de crises convulsivas e instabilidade hemodinâmica em razão de bloqueio atrioventricular completo. Estas manifestações se associaram a múltiplos episódios de taquicardia ventricular sustentada; não havia alterações estruturais cardíacas, nem se detectaram distúrbios hidroeletrolíticos. Na unidade de terapia intensiva, a paciente foi submetida à implantação de marca-passo provisório, imunossupressão com uso de corticosteroides e terapia imunobiológica, resultando em melhora hemodinâmica completa. Distúrbios graves da condução cardíaca em pacientes com granulomatose com poliangiíte são raros, mas associam-se à grande morbidade. O reconhecimento precoce e o uso de intervenções específicas são capazes de prevenir a ocorrência de desfechos desfavoráveis, especialmente na unidade de terapia intensiva.

Ultrasound-guided percutaneous dilational tracheostomy versus bronchoscopy-guided percutaneous dilational tracheostomy in critically ill patients (TRACHUS): a randomized noninferiority controlled trial.

PURPOSE: Percutaneous dilational tracheostomy (PDT) is routinely performed in the intensive care unit with bronchoscopy guidance. Recently, ultrasound has emerged as a potentially useful tool to assist PDT and reduce procedure-related complications. METHODS: An open-label, parallel, non-inferiority randomized controlled trial was conducted comparing an ultrasound-guided PDT with a bronchoscopy-guided PDT in mechanically ventilated critically ill patients. The primary outcome was procedure failure, defined as a composite end-point of conversion to a surgical tracheostomy, unplanned associated use of bronchoscopy or ultrasound during PDT, or the occurrence of a major complication. RESULTS: A total of 4965 patients were assessed for eligibility. Of these, 171 patients were eligible and 118 underwent the procedure, with 60 patients randomly assigned to the ultrasound group and 58 patients to the bronchoscopy group. Procedure failure occurred in one (1.7%) patient in the ultrasound group and one (1.7%) patient in the bronchoscopy group, with no absolute risk difference between the groups (90% confidence interval, -5.57 to 5.85), in the "as treated" analysis, not including the prespecified margin of 6% for noninferiority. No other patient had any major complication in either group. Procedure-related minor complications occurred in 20 (33.3%) patients in the ultrasound group and in 12 (20.7%) patients in the bronchoscopy group (P = 0.122). The median procedure length was 11 [7-19] vs. 13 [8-20] min (P = 0.468), respectively, and the clinical outcomes were also not different between the groups. CONCLUSIONS: Ultrasound-guided PDT is noninferior to bronchoscopy-guided PDT in mechanically ventilated critically ill patients.

RESUMO Introdução: Simulações são amplamente utilizadas na educação médica, mas há pouca evidência de sua eficácia no tratamento de pacientes neurocríticos. Como o acidente vascular cerebral agudo (AVC) é uma patologia que requer atendimento imediato, o uso de simulação pode ser uma ferramenta útil no treinamento do manejo desses pacientes. Objetivo: Avaliar o impacto do uso de simulação realística na autopercepção de segurança no atendimento a pacientes vítimas de AVC agudo. Métodos: Estudo antes-depois controlado. No grupo da intervenção, 17 profissionais da área de saúde participaram de um curso de simulação realística de atendimento a pacientes com AVC. Como controles, os participantes foram escolhidos a partir de uma amostra de conveniência composta por 18 participantes do curso Emergency Neurologic Life Support (ENLS) e 20 participantes de um curso de Neurossonologia. Foram respondidos questionários antes e após o curso para avaliar a autopercepção de segurança no atendimento a pacientes vítimas de AVC agudo, variando de 10 a 50 pontos. Foi avaliada a variação entre os resultados pré- e pós-teste, para avaliar a mudança na autopercepção de confiança do trainee no manejo do AVC agudo. Análise multivariada foi realizada para controlar possíveis fatores de confusão. Resultados: Quarenta e seis (83,63%) participantes responderam aos questionários. A pontuação no questionário pós-curso foi maior do que a obtida no questionário pré-curso no grupo de participantes do curso de simulação realística em AVC [mediana do questionário pré-curso: 41,5 (36,7-46,5) e mediana do questionário pós-curso: 47,0 (44,7-48,0); p=0,033]. Essa diferença não foi observada no curso de Neurossonologia [mediana pré-curso (IQR): 46,0 (44,0-47,00), mediana pós-curso (IQR): 46,0 (44,0-47,0); p=0,739] nem no ENLS [mediana pré-curso (IQR): 46,5 (39,0-48,2) mediana pós-curso (IQR): 47,0 (40,2-49,0); p=0,317]. Esses resultados persistiram após ajuste das variáveis. Conclusão: O curso de simulação realística em AVC foi associado a um aumento na autopercepção de segurança dos participantes em atender pacientes vítimas de AVC agudo.

Fluid and electrolyte overload in critically ill patients: An overview.

Fluids are considered the cornerstone of therapy for many shock states, particularly states that are associated with relative or absolute hypovolemia. Fluids are also commonly used for many other purposes, such as renal protection from endogenous and exogenous substances, for the safe dilution of medications and as "maintenance" fluids. However, a large amount of evidence from the last decade has shown that fluids can have deleterious effects on several organ functions, both from excessive amounts of fluids and from their non-physiological electrolyte composition. Additionally, fluid prescription is more common in patients with systemic inflammatory response syndrome whose kidneys may have impaired mechanisms of electrolyte and free water excretion. These processes have been studied as separate entities (hypernatremia, hyperchloremic acidosis and progressive fluid accumulation) leading to worse outcomes in many clinical scenarios, including but not limited to acute kidney injury, worsening respiratory function, higher mortality and higher hospital and intensive care unit length-of-stays. In this review, we synthesize this evidence and describe this phenomenon as fluid and electrolyte overload with potentially deleterious effects. Finally, we propose a strategy to safely use fluids and thereafter wean patients from fluids, along with other caveats to be considered when dealing with fluids in the intensive care unit.

Comparison between ultrasound- and bronchoscopy-guided percutaneous dilational tracheostomy in critically ill patients: a retrospective cohort study.

INTRODUCTION: Percutaneous dilational tracheostomy (PDT) is routinely performed in the intensive care unit with bronchoscopic guidance. Recently, ultrasound (US) has emerged as a new safety adjunct tool to increase the efficacy of PDT. However, the available data are limited to case series without any control group. Hence, a retrospective cohort study was designed to evaluate the efficacy of US-guided PDT compared with bronchoscopy-guided PDT. METHODS: All patients who were submitted to PDT after the standardization of US-guided PDT technique in our institution were analyzed. Demographic and procedure-related variables, complications, and clinical outcomes were collected and compared in patients undergoing US- or bronchoscopy-guided PDT. RESULTS: Sixty patients who had been submitted to PDT were studied, including 11 under bronchoscopy guidance and 49 under US guidance. No surgical conversion was necessary in any of the procedures, and bronchoscopy assistance was only required in 1 case in the US group. The procedure length was shorter in the US group than in the bronchoscopy group (12 vs 15 minutes, P = .028). None of the patients had any major complications. The minor complication rates were not significantly different between the groups, nor was the probability of breathing without assistance within 28 days, intensive care unit length of stay, or hospital mortality. CONCLUSION: Ultrasound-guided PDT is effective, safe, and associated with similar complication rates and clinical outcomes compared with bronchoscopy-guided PDT.

Razão TG/HDL-c, indicadores antropométricos e bioquímicos de risco cardiovascular no renal crônico em tratamento conservador / TG/HDL-c reason, anthropometrics and biochemical indicators of cardiovascular risk in chronic renal in conservative treatment

Introdução: As doenças cardiovasculares (DCV) representam no Brasil a principal causa de morbimortalidade e sua prevalência cresce em todo o mundo. O paciente com doença renal crônica apresenta alto risco de desenvolvimento da doença e este risco eleva-se na presença de dislipidemia. Triglicérides (TG) elevado e lipoproteína de alta densidade (HDL-c) reduzida são preditores independentes de eventos cardiometabólicos. O excesso de tecido adiposo também está envolvida com risco de DCV. Portanto a utilização de preditores do desenvolvimento de DCV, como a razão triglicerídeos/HDL colesterol (TG/HDL-c) e indicadores antropométricos de avaliação de gordura corporal são importantes na prática clínica. Objetivo: Avaliar a associação entre a razão TG/HDL e indicadores antropométricos de risco cardiovascular em pacientes renais crônicos em tratamento conservador. Métodos: Estudo transversal, envolvendo 90 pacientes clinicamente estáveis atendidos ambulatorialmente. A razão TG/HDL-c foi definida de acordo com equação preestabelecida, sendo considerado risco para DCV valores >2,5 para mulheres e >3,5 para homens. Os parâmetros antropométricos utilizados foram o índice de massa corporal (IMC) e a circunferência da cintura (CC). Dados sociais, de estilo de vida, clínicos e bioquímicos também foram coletados. Na comparação entre os dois grupos (razão TG/HDL-c elevado e razão TG/HDL adequado) foi utilizado o teste t de Student para os dados paramétricos e de Mann-Whitney para os dados não paramétricos. As proporções foram comparadas pelo teste do quiquadrado. Os ajustes entre Razão TG/HDL, IMC e CC foram realizadas através da análise de regressão logística. Resultados: Da amostra avaliada, 50 pacientes (55,6%) apresentaram razão TG/HDL elevada. Pacientes com IMC e CC alterada apresentavam maior risco de DCV, avaliado através da razão TG/HDL-c. Houve diferença estatisticamente significante entre os indicadores antropométricos utilizados, IMC e CC, e razão TG/HDL-c quando estratificado em elevado e adequado. Entretanto, na análise ajustada, não foi observada associação entre o IMC ou a CC e a razão TG/HDL. Conclusão: Os resultados demonstram que após ajustes com possíveis variáveis de confusão não houve associação entre os valores da razão TG / HDL-C e indicadores antropométricos de adiposidade, IMC e CC. Os resultados deste estudo levam a questionar a real influência do excesso de peso e da obesidade central na razão TG/HDL-c (AU)

Introduction: Cardiovascular diseases (CVD) are a major cause of morbidity and mortality, and its prevalence is growing worldwide. Patients with chronic kidney disease (CKD) are at high risk of group, especially those with dyslipidemia. Triglycerides (TG) and high-density lipoprotein (HDL-c) are independent predictors of cardiovascular events. Excessive adipose tissue also increases the cardiovascular risk. Therefore, CVD predictors, such as the Triglycerides / HDL cholesterol (TG / HDL-c) ratio and the anthropometric measurements for assessing body fat are important in clinical practice. Objective: To evaluate the association between TG / HDL ratio, anthropometric measurements and the cardiovascular risk in CKD patients on dialysis. Methods: A cross-sectional study involving 90 clinically stable outpatients. The TG / HDL-c ratio was defined according to a predetermined equation, considering high CVD risk values greater than 2.5 for women and greater than 3.5 for men. The anthropometric parameters used were the body mass index (BMI) and the waist circumference (WC). Social data, lifestyle, clinical and biochemical data were also collected. Results: Fifty patients (55.6%) had a high TG / HDL ratio. Patients with abnormal BMI and WC were at a higher cardiovascular risk, as measured by the TG / HDL-c ratio. There was a statistically significant difference between the anthropometric measurements (BMI and the WC), and the TG / HDL-c ratio in the stratified analysis. However, in the adjusted analysis no association between the BMI or the WC and the TG/HDL ratio was observed. Conclusion: There was no association between the TG / HDL-C ratio and the adiposity measurements (BMI and WC) in the adjusted analysis. The results of this study question the real influence of overweight and central obesity in the TG / HDL-c ratio (AU)

Distúrbios de condução cardíaca e taquicardia ventricular como complicação da granulomatose com poliangiíte em uma paciente. Relato de caso e revisão da literatura / Heart conduction system defects and sustained ventricular tachycardia complications in a patient with granulomatosis with polyangiitis. A case report and literature review

RESUMO A granulomatose com poliangiíte é um raro distúrbio inflamatório sistêmico que se caracteriza por vasculite de pequenas artérias, arteríolas e capilares, associada a lesões granulomatosas necrotizantes. Este artigo relata o caso de uma paciente com diagnóstico prévio de granulomatose com poliangiíte, admitida à unidade de terapia intensiva com quadro de crises convulsivas e instabilidade hemodinâmica em razão de bloqueio atrioventricular completo. Estas manifestações se associaram a múltiplos episódios de taquicardia ventricular sustentada; não havia alterações estruturais cardíacas, nem se detectaram distúrbios hidroeletrolíticos. Na unidade de terapia intensiva, a paciente foi submetida à implantação de marca-passo provisório, imunossupressão com uso de corticosteroides e terapia imunobiológica, resultando em melhora hemodinâmica completa. Distúrbios graves da condução cardíaca em pacientes com granulomatose com poliangiíte são raros, mas associam-se à grande morbidade. O reconhecimento precoce e o uso de intervenções específicas são capazes de prevenir a ocorrência de desfechos desfavoráveis, especialmente na unidade de terapia intensiva.

ABSTRACT Granulomatosis with polyangiitis is a rare systemic inflammatory disorder characterized by vasculitis of the small arteries, the arterioles and the capillaries together with necrotizing granulomatous lesions. This case reports on a young female patient, previously diagnosed with granulomatosis with polyangiitis, who was admitted to the intensive care unit with seizures and hemodynamic instability due to a complete atrioventricular heart block. The event was associated with multiple episodes of sustained ventricular tachycardia without any structural heart changes or electrolyte disturbances. In the intensive care unit, the patient was fitted with a provisory pacemaker, followed by immunosuppression with corticosteroids and immunobiological therapy, resulting in a total hemodynamic improvement. Severe conduction disorders in patients presenting granulomatosis with polyangiitis are rare but can contribute to increased morbidity. Early detection and specific intervention can prevent unfavorable outcomes, specifically in the intensive care unit.

Inflammatory, nutritional and clinical parameters of individuals with chronic kidney disease undergoing conservative treatment / Inflamación, estado clínico y nutricional de pacientes renales crónicos en tratamiento conservador

Introduction: due to the relevance of inflammation in individuals with chronic kidney disease (CKD), inflammation should be taken into account in the interpretation of the clinical-nutritional status. Objective: assess the association between inflammation, nutritional and clinical parameters in patients with CKD. Materials and methods: 92 patients with CKD. C-reactive protein (CRP) was used as an inflammation marker. Assessed nutritional parameters were anthropometry and biochemical exams. Evaluated clinical parameters were comorbidities, CKD characteristics, lipid profile, lipid-lowering agents, urea, creatinine and total leukocytes. Comparisons between two groups (with or without inflammation) were performed using Student’s t-test or chi-square test. Results: 15 (16.3%) patients had CRP above greater than or equal to 10mg/L and were considered with inflammation. In the group with inflammation, 05 (33%) had hypoalbuminemia as compared with 05 (6.5%) in the group without inflammation (p = 0.002). Lipid values were lower in the group with inflammation, with mean total cholesterol 171 (± 41.2) mg/dL and mean LDL-C 95 (± 31.2) mg/dL as compared with the group without inflammation, which had and a mean total cholesterol 198 (± 46) mg/dL and mean LDL-C 124 (± 40.1) mg/dL, p = 0,038 and p = 0.011, respectively. No other statistically significant differences between groups were found. Conclusion: inflammation was associated with changes in the total cholesterol and LDL levels and with an increased incidence of hypoalbuminemia. We suggest that serum albumin levels should only be used to assess nutritional status in the absence of inflammation and CRP levels ought to be considered in nutritional status interpretation in patients with CKD (AU)

Introducción: la inflamación es un problema frecuente en pacientes con enfermedad renal crónica (ERC) y se debe relacionar con el estado clínico y nutricional de estos. Objetivo: evaluar si existe una asociación entre la inflamación y los parámetros clínicos y nutricionales en los pacientes con ERC. Material y métodos: fueron evaluados 92 pacientes con ERC. Se utilizo la proteína C reactiva (PCR) como marcador de la inflamación. Los parámetros nutricionales evaluados fueron antropometría y exámenes bioquímicos. Los parámetros clínicos evaluados fueron comorbilidades, características de la ERC, perfil lipidico, hipolipemiantes, urea, creatinina y leucocitos totales. Para analizar las diferencias entre los grupos (con o sin inflamación) se utilizo el test t de Student o el test de Chi-cuadrado. Resultados: 15 pacientes (16,3%) presentaban PCR más o igual a 10,0 mg/dL y tenían inflamación. De estos, 05 (33%) tuvieron hipoalbuminemia, en comparacion con 05 (6,5%) en el grupo sin inflamación (p = 0,002). Los valores de lípidos fueron inferiores en el grupo con inflamación, con colesterol total medio de 171 mg/dL (} 41,2) e LDL-C medio de 95 mg / dL (} 31,2) en comparación con aquellos sin inflamación con medias de 198 mg / dL (} 46) y 124 mg/dL (} 40,1), respectivamente. No se encontraron otras diferencias significativas entre los grupos. Conclusión: la inflamación se ha asociado con modificaciones en el colesterol total, LDL e hipoalbuminemia. Se concluye que la albumina sérica solo se debe utilizar para evaluar el estado nutricional en ausencia de inflamación. El nivel de PCR es un marcador sensible de la inflamación y debe ser empleado en la interpretación del estado nutricional en pacientes con ERC (AU)
