RESUMO

The Henoch-Schönlein purpura (HSP) is a small vessel vasculitis with IgA immune complex deposition. The presentation in adults is rare and severe. Reported cases of HSP in patients infected with HIV are scarce. Neutrophil cytoplasmic antibodies (ANCA) are commonly found in other systemic vasculitis, but rarely in HSP and even more unusual the perinuclear pattern. Beside small vessel vasculitis, positivity of ANCA can be detected in a number of different pathological conditions in association with infectious processes, including HIV, or cocaine use, and especially the pattern of ANCA-p, associated with drugs, inflammatory bowel or autoimmune diseases. We report the case of a 35 years old man with toxic habits (cocaine, marijuana) who consulted for abdominal pain, hematochezia and purpura on lower extremities, and later fever, joint pain and progression of purpura associated with nephritic syndrome and ANCA-p (+). During hospitalization HIV infection was detected. Renal biopsy showed IgA nephropathy with favorable response to corticosteroid and antiproteinuric treatment. The communication of the case is due to the rarity of the presentation and therapeutic diagnostic challenge. It remains to elucidate the role of ANCA in the pathogenesis and management of adult PSH.

RESUMO

Introduction: Introduction: sarcopenia is characterized by loss of muscle mass and function. Spinal disorders are a risk factor for muscle deterioration. In turn, sarcopenia is associated with adverse outcomes in the postoperative period of spinal surgery. Objectives: to evaluate sarcopenia and the relationship of muscle strength with bioimpedance parameters in the preoperative consultation. Material and methods: cross-sectional observational study. Muscle strength (dynamometry) and body composition (bioimpedance spectroscopy) were measured as part of the functional assessment of nutritional status. Sarcopenia was defined according to the European Working Group on Sarcopenia in Older People 2019 (EGWSOP2) and dynapenia/myopenia in the case of low strength or isolated muscularity. The relationship between the dynamometry values and the bioimpedance variables was summarized with the Spearman's coefficient. Results: twenty-two patients were included. The median (IQR) age was 60 years (43-65) and 72 % were women. The most frequent diagnosis and surgical procedure was spondylolisthesis (45 %) and posterior fixation (50 %). The mean body mass index (BMI) was 28.3 (± 4.59) kg/m2. The presence of sarcopenia, dynapenia and myopenia was 18.2 %, 13.6 % and 22.7 %, respectively. Dynamometry was correlated with lean tissue index: 0.61 (p 0.002); body cell mass: 0.68 (p 0.000); appendicular skeletal muscle: 0.49 (p 0.021); phase angle: 0.46 (p 0.031); and resistance index 200/5 kHz: -0.47 (p 0.028). Conclusion: muscle strength is correlated with bioimpedance parameters. Sarcopenia, dynapenia and myopenia are frequent and objectifiable in the preoperative spinal surgery consultation.


Introducción: Introducción: la sarcopenia se caracteriza por la pérdida de masa y función muscular. Los trastornos de la columna vertebral son un factor de riesgo del deterioro muscular. A su vez, la sarcopenia se asocia a resultados adversos en el postoperatorio de cirugía espinal. Objetivos: evaluar sarcopenia y la relación de la fuerza muscular con parámetros de la bioimpedancia en la consulta preoperatoria. Material y métodos: estudio observacional transversal. Se midieron fuerza muscular (dinamometría) y composición corporal (bioimpedancia por espectroscopia) en el marco de la evaluación funcional del estado nutricional. Sarcopenia se definió según el Grupo de Trabajo Europeo sobre Sarcopenia en Personas Mayores (EGWSOP2) y dinapenia/miopenia, en caso de baja fuerza o muscularidad aislada. La relación entre los valores de la dinamometría y las variables de la bioimpedancia se resumió con el coeficiente de Spearman. Resultados: se incluyeron 22 pacientes. La mediana (RIQ) de edad fue de 60 (43-65) años y el 72 %, de sexo femenino. El diagnóstico y el procedimiento quirúrgico más frecuentes fueron espondilolistesis (45 %) y fijación posterior (50 %). El índice de masa corporal (IMC) promedio fue de 28,3 (± 4,59) kg/m2. La presencia de sarcopenia, dinapenia y miopenia fue del 18,2 %, 13,6 % y 22,7 %, respectivamente. La dinamometría se correlacionó con el índice de tejido magro: 0,61 (p 0,002); masa celular corporal: 0,68 (p 0,000); músculo esquelético apendicular: 0,49 (p 0,021); ángulo de fase: 0,46 (p 0,031); e índice de resistencia 200/5 kHz: -0,47 (p 0,028). Conclusión: la fuerza muscular se correlaciona con los parámetros de la bioimpedancia. La sarcopenia, dinapenia y miopenia es frecuente y objetivable en la consulta preoperatoria de cirugía espinal.

RESUMO

Introduction: Introduction: variants of the NUTRIC score with or without inflammatory biomarkers, modified without interleukin 6 (IL-6) (NUTRICm), with C-reactive protein (CRP) instead of IL-6, dichotomous (NUTRICpcr1) or in tertiles (NUTRICpcr2), were proposed to assess nutritional risk (NR) in critical patients. However, the assessment of the high NR might not be uniform between these scores. Objectives: to compare the assessment of the high NR by NUTRICm and the two variants of the NUTRICpcr. Material and methods: analysis of a prospective cohort of patients ventilated prior to COVID-19. Agreement was analyzed using the Kappa test and mortality discrimination by logistic regression. The proportion of patients with high NR was compared with the Chi-square test. Results: five hundred and fifty patients were analyzed. Median (IQR) age and APACHE II: 44 (28-58) years and 17 (12-22) points, predominant traumatic pathology (38.2 %) and Intensive Care Unit (ICU) mortality of 32.5 %. The concordance was high between NUTRICm and NUTRICpcr1 (Kappa = 0.81) and lower between NUTRICm and NUTRICpcr2 (Kappa = 0.60). The AUCROC (95 % CI) of NUTRICm, NUTRICpcr1 and NUTRICpcr2 to discriminate mortality was 0.695 (0.495-0.591), 0.693 (0.495-0.591) and 0.685 (0.495-0.591), respectively. The tall NB showed significant differences between NUTRICm and NUTRICpcr1 (19.8 % vs 14.4 %, p 0.0243), being greater between NUTRICm and NUTRICpcr2 (19.8 vs 9.8 %, p < 0.0001). Conclusion: the three NUTRIC variants studied discriminate mortality in a similar way. However, the NUTRICm, without an inflammatory biomarker, classifies more patients as high nutritional risk.


Introducción: Introducción: las variantes del puntaje NUTRIC con o sin biomarcadores inflamatorios, modificada sin interleucina-6 (IL-6) (NUTRICm), con proteína C reactiva (PCR) en lugar de IL-6, dicotómica (NUTRICpcr1) o en terciles (NUTRICpcr2), se propusieron para evaluar el riesgo nutricional (RN) en pacientes críticos. Sin embargo, la valoración del RN alto podría no ser uniforme entre dichos puntajes.. Objetivos: comparar la valoración del RN alto por NUTRICm y las dos variantes del NUTRICpcr. Material y métodos: análisis de una cohorte prospectiva de pacientes ventilados previa al COVID-19. El acuerdo se analizó mediante la prueba de Kappa y la discriminación de la mortalidad por regresión logística. La proporción de pacientes de RN alto se comparó con la prueba Chi-cuadrado. Resultados: se analizaron 550 pacientes. Mediana (RIQ) de edad y APACHE II: 44 (28-58) años y 17 (12-22) puntos, patología traumática predominante (38,2 %) y mortalidad en Unidad de Cuidados Intensivos (UCI) del 32,5 %. La concordancia fue alta entre NUTRICm y NUTRICpcr1 (Kappa = 0,81) y menor entre NUTRICm y NUTRICpcr2 (Kappa = 0,60). El AUCROC (IC 95 %) del NUTRICm, NUTRICpcr1 y NUTRICpcr2 para discriminar mortalidad fue de 0,695 (0,495-0,591), 0,693 (0,495-0,591) y 0,685 (0,495-0,591), respectivamente. El RN alto mostró diferencias significativas entre NUTRICm y NUTRICpcr1 (19,8 % vs. 14,4 %, p 0,0243), y fue mayor entre NUTRICm y NUTRICpcr2 (19,8 vs. 9,8 %, p < 0,0001). Conclusión: las tres variantes del NUTRIC estudiadas discriminan la mortalidad en forma similar. Sin embargo, el NUTRICm, sin biomarcador inflamatorio, clasifica más pacientes como de RN alto.

RESUMO

The term pseudoascitis is used in patients who give the false impression of ascites, with abdominal distension but without peritoneal free fluid. The case of a 66-year-old woman, hypertensive and hypothyroid with occasional alcohol consumption, who consults due to progressive abdominal distension of 6 months of evolution and diffuse percussion dullness is presented, in whom a paracentesis is performed with the wrong endorsement of examination ultrasound that reports abundant intrabdominal free fluid (Fig. 1), later finding in the CT scan of the abdomen and pelvis an expansive process of cystic appearance of 295mm x 208mm x 250mm. Left anexectomy is programmed (Fig. 2) with pathological report of mucinous ovarian cystadenoma. The case report refers to the availability of the giant ovarian cyst within the differential diagnosis of ascites. If no symptoms or obvious signs of liver, kidney, heart or malignant disease are found and / or ultrasound does not reveal typical signs of intra-abdominal free fluid (fluid in the bottom of the Morrison or Douglas sac, presence of floating free intestinal handles), a CT scan and / or an RMI should be requested before performing paracentesis, which could have potentially serious consequences.


El término pseudoascitis, se utiliza en los pacientes que dan la falsa impresión de ascitis, con distensión abdominal pero sin líquido libre peritoneal. Se presenta el caso de una mujer de 66 años, hipertensa e hipotiroidea con consumo ocasional de alcohol, que consulta por distensión abdominal progresiva de 6 meses de evolución y matidez difusa a la percusión, en quien se realiza una paracentesis con el aval equivoco de examen ecográfico que informa abundante líquido libre  intrabdominal (Fig. 1), hallando posteriormente en TAC de abdomen y pelvis un proceso expansivo de aspecto quístico de 295mm x 208mm x 250mm. Se programa anexectomia izquierda (Fig. 2) con informe anatomopatológico de cistoadenoma mucinoso de ovario. La comunicación del caso remite a tener disponible el quiste ovárico gigante dentro de los diagnósticos diferenciales de ascitis. Si no se hallan síntomas o signos evidentes de insuficiencia hepática, renal, cardiaca o enfermedad maligna y/o la ecografía no revela signos típicos de líquido libre intrabdominal  (líquido en el fondo de saco de Morrison o de Douglas, presencia de asas intestinales libres flotantes), se debería solicitar una TAC y/o una RMI antes de realizar una paracentesis, la cual podría tener consecuencias potencialmente graves.

RESUMO

The PROFUND index was developed and valid to predict mortality at 12 months in polypathological patients (PP). However, its potential value for predicting in-hospital mortality has not been sufficiently studied. The ability of the PROFUND index in comparison with C-reactive protein (CRP), albumin, and red blood cell distribution width (RDW) to predict in-hospital mortality was evaluated through the subsequent analysis of a prospective cohort of 111 multiple pathological patients admitted to the clinic medical. The mean age was 75.8 ± 9.3 years. In-hospital mortality was 17% (19 patients). The median (IQR) of the PROFUND index, albumin, CRP and ADE in the deceased and survivors was 12 (4) and 6 (7) p < 0.0001, 2.5 (0.4) and 2.6 (0.8) p 0.295, 58 (64) and 40 (60) p 0.176, 14.5 (2) and 14.6 (3) p 0.523, respectively. The multivariate logistic analysis showed that the PROFUND index is associated with in-hospital mortality (p 0.0003). The risk of dying during hospitalization is 20% higher for each point that the PROFUND index increases (OR 1.2, 95% CI 1.1-1.4). The area under the curve the receiver operating characteristic (AUC-ROC) of the PROFUND index to predict mortality during hospitalization (0.760, 95% CI 0.628-0.891) was higher than that of the RDW, CRP and albumin (0.494 95% CI 0.364-0.624 p 0.012; 0.583 95% CI 0.437-0.728 p 0.028; 0.621 0.494-0.748 p 0.109, respectively). The PROFUND index is associated with in-hospital mortality, with a greater predictive capacity than the biomarkers studied, which would add to its long-term prognostic value in multiple pathological patients.


El índice PROFUND se desarrolló y validó para predecir mortalidad a 12 meses en pacientes pluripatológicos. Sin embargo, su valor potencial para predecir mortalidad intrahospitalaria no ha sido suficientemente estudiado. Se evaluó la capacidad del índice PROFUND en comparación con la proteína C reactiva (PCR), la albúmina, y el ancho de distribución eritrocitaria (ADE) para predecir mortalidad intrahospitalaria, mediante el análisis posterior de una cohorte prospectiva de 111 pacientes pluripatológicos internados en clínica médica. La edad promedio fue 75.8 ± 9.3 años. La mortalidad intrahospitalaria fue de 17% (19 pacientes). La mediana (RIQ) del índice PROFUND, albúmina, PCR y ADE en los fallecidos y sobrevivientes fue 12 (4) y 6 (7) p < 0.0001, 2.5 (0.4) y 2.6 (0.8) p 0.295, 58 (64) y 40 (60) p 0.176, 14.5 (2) y 14.6 (3) p 0.523, respectivamente. El análisis logístico multivariado mostró que el índice PROFUND se asocia con mortalidad intrahospitalaria (p 0.0003). El riesgo de fallecer durante la internación es 20% mayor por cada punto que se incrementa el índice PROFUND (OR 1.2, IC95% 1.1-1.4). El área bajo la curva de las características operativas del receptor (AUCROC) del índice PROFUND para predecir mortalidad durante la internación (0.760, IC95% 0.628-0.891) fue mayor a la del ADE, PCR y albúmina (0.494 IC95% 0.364-0.624 p 0.012; 0.583 IC95% 0.437-0.728 p 0.028; 0.621 0.494-0.748 p 0.109, respectivamente). El índice PROFUND se asocia a mortalidad intrahospitalaria, con una mayor capacidad predictiva que los biomarcadores estudiados, lo cual se sumaría a su valor pronóstico a largo plazo en pacientes pluripatológicos.

RESUMO

Introduction: To study in Pluripathological patients (PP) if the PROFUND index, an objective multidimensional prognostic score, is superior to the intuition of the clinician to predict death during the first year of follow-up after hospitalization in a general ward. Methods: Prospective and observational study. Adult pluripathological patients were included. Variables: PROFUND index, subjective prognosis of death (PSM). Do you think this patient will die in the next 12 months?: "yes" PSM (+) "no" PSM (-). Mortality 12 months after discharge. Results: 92 patients were analyzed. The average age was 75.3 (± 9.5) years and 51.1% male. 47 patients (51.6%) died. The average PROFUND index was 6.9 (± 4.5) points and the PS was (+) at 46.7%. Within follow-up, 65.9% (29 of 44) and 38.3% (18 of 47) of patients with a PROFUND index> 6 and ≤6 points, respectively, died (p = 0.0021). Of the 43 patients with PS (+) 58.1% died and of the 48 with PS (-) 45.8% (p = 0.1003). From the Cox model, the risk of dying is 2 times higher in patients with a PROFUND index> 6 points (HR: 2,269 95% CI: 1,231-4,184). The AUC to predict 12-month mortality from the PROFUND index and PS were: 0.712 (95% CI: 0.607-0.817) and 0.561 (95% CI: 0.458-0.664) respectively (p 0.0212). Conclusion: In hospitalized patients with pluripathology, the PROFUND index exceeds the 12-month mortality prognostic capacity of the treating clinician.

RESUMO

Polycystic Ovary Syndrome (PCOS) is an endocrine/metabolic disorder with an ever-increasing prevalence. It has various clinical characteristics; the cardinals are androgen excess, oligo-anovulatory infertility, polycystic ovaries, insulin resistance (IR), and cardiometabolic alterations. These disturbances are a consequence of PCOS's complex etiology. PCOS is mainly related to women with obesity; however, there are many PCOS lean patients too. Even though they share some aspects in their metabolic profiles, each group has individual differences in body composition and other parameters. Thus, in order to achieve successful therapeutic strategies, they should be tailored to these details. The authors reviewed PubMed's updated and related publications about body composition and nutritional strategies for PCOS lean and obese patients. As previous reports have determined, dietary patterns are essential in PCOS treatment. Several diets have been studied to control and improve IR, infertility, and cardiometabolic dysfunctions in PCOS. This review will explain the specific features in metabolic characterization and body composition among these patients. Finally, the diverse nutritional strategies used in women with PCOS will be analyzed depending on their lean or obese phenotype.

RESUMO

OBJECTIVE: To study the ability of the urea/creatinine index to identify severe protein catabolism from the isolated urine of critically ventilated patients. METHODS: This was a prospective, observational study. It included 52 patients without kidney failure. Variables: total urinary nitrogen estimated from the urea in 24-hour urine on the second (T1) and fourth days (T2) and urea/creatinine index in isolated urine before 24-hour urine collection. RESULTS: Severe protein hypercatabolism (estimated total urinary nitrogen > 15g) was present in 14 patients (26.9%) at T1 and in 29 (55.7%) at T2. Eighty-four percent of patients had low nutritional risk by the Nutrition Risk in the Critically Ill score. At T1, the Pearson correlation between the estimated total urinary nitrogen and the urea/creatinine index was 0.272 (p = 0.051), and at T2 it was 0.276 (p = 0.048). The urea/creatinine index at T2 had a tendency to better discriminate severe protein hypercatabolism than Acute Physiology and Chronic Health Evaluation II and Nutrition Risk in the Critically Ill (AUC 0.741 versus 0.669 and 0.656, 95%CI: 0.602 - 0.880; 0.519 - 0.818 and 0.506 - 0.806, respectively). The optimal cutoff value of the urea/creatinine index for the diagnosis of severe protein hypercatabolism was 16.15, with a sensitivity of 79.31% (95%CI: 59.74 - 91.29), specificity of 60.87% (95%CI: 38.78 - 79.53), positive predictive value 71.88% (95%CI: 53.02 - 85.60), negative predictive value 70.0% (95%CI: 45.67 - 87.18), LR (+) 2.03 (95%CI: 1.18 - 3.49), and LR (-) 0.34 (95%CI: 0.16 - 0.74). CONCLUSION: The urea/creatinine index measured on the fourth day has a certain ability to estimate severe protein hypercatabolism (as defined by estimated total urinary nitrogen) but does not replace total urinary nitrogen in critically ventilated patients without kidney failure. Due to its reasonable sensitivity, it could be used as a screen to identify which patients to take a 24-hour urine sample from.


OBJETIVO: Estudiar la capacidad discriminativa de hipercatabolismo proteico grave del índice urea/creatinina en orina aislada en pacientes críticos ventilados. METODOS: Estudio prospectivo, observacional. Incluyó 52 pacientes sin insuficiencia renal. Variables: nitrógeno urinario total estimado a partir de la urea en orina de 24 horas al segundo (T1) y cuarto día (T2) e índice urea/creatinina en orina aislada previo a la recolección de orina de 24 horas. RESULTADOS: Presentaron hipercatabolismo proteico grave (nitrógeno urinario total estimado > 15g) 14 pacientes (26,9%) en T1 y 29 (55,7%) en T2. El 84% de los pacientes presentaron bajo riesgo nutricional por la escala Nutrition Risk in the Critically Ill. En el segundo día, la correlación de Pearson del nitrógeno urinario total estimado con el índice urea/creatinina fue: 0,272 (p = 0,051) y en el cuarto día: 0,276 (p = 0,048). El índice urea/creatinina al cuarto día, tuvo una tendencia a mayor discriminación del hipercatabolismo proteico grave que el Acute Physiology and Chronic Health Evaluation II y Nutrition Risk in the Critically Ill (AUC 0,741 versus 0,669 y 0,656, IC95%: 0,602 - 0,880; 0,519 - 0,818 y 0,506 - 0,806 respectivamente). El valor de corte optimo del índice urea/creatinina para diagnóstico de hipercatabolismo proteico grave fue de 16,15 con una sensibilidad de 79,31% (IC95%: 59,74 - 91,29), especificidad de 60,87% (IC95%: 38,78 - 79,53), valor predictivo positivo 71,88% (IC95%: 53,02 - 85,60), valor predictivo negativo 70,0% (IC95%: 45,67 - 87,18), LR (+) 2,03 (IC95%: 1,18 - 3,49) y LR (-) 0,34 (IC95%: 0,16 - 0,74). CONCLUSIÓN: El índice urea/creatinina realizado al cuarto día tiene un discreto valor para estimar el hipercatabolismo proteico grave por nitrógeno urinario total y no reemplaza al mismo en pacientes críticos ventilados sin falla renal. Por su razonable sensibilidad podría ser utilizado como cribado para identificar a quien tomar la muestra de orina de 24 horas.

RESUMO

The PROFUND index is one of the suggested prognostic scores in pluripathological patients (PP). Despite the prognostic value of malnutrition and its prevalence in this population, it does not include a variable that estimates nutritional status. Subjective global assessment (SGA) is a widely validated tool for this purpose. The prognostic capacity of 12-month mortality of PROFUND index and SGA in PP admitted to a medical clinic was evaluated by a prospective and observational study. 111 patients entered the study. Age 75.8 (± 9.3) years. PROFUND index 7.6 (± 4.7) points. 60.1% had moderate-severe malnutrition due to VGS. 66 died within the year. In the Cox model, SGA and PROFUND index are associated with mortality at 12 months (p < 0.0001 and p 0.0026 respectively). In severe malnutrition, the risk is approximately 6 times higher compared to normonutrition (HR: 6.514, 95% CI 2.826-15.016) and for the same level of SGA, the risk is 10% higher for each point that the PROFUND index increases (HR: 1.106, 95% CI 1.036-1.181). The AUC for predicting 12-month mortality from PROFUND index and SGA was: 0.747 (95% CI: 0.656-0.838); 0.733 (95% CI: 0.651-0.816) and when combining the two variables: 0.788 (95% CI: 0.703-0.872, p 0.048). In conclusion, PROFUND index and SGA are associated with mortality and have a similar prognostic value. The combination of both tools would allow better prognosis and management in this complex population.


El índice PROFUND es una de las puntuaciones pronósticas sugeridas en pacientes pluripatológicos (PP). A pesar del valor pronóstico de la desnutrición y su prevalencia en esta población, el mismo no incluye una variable que estime el estado nutricional. La valoración global subjetiva (VGS) es una herramienta ampliamente validada para tal fin. Se evaluó mediante un estudio prospectivo y observacional, la capacidad pronóstica de mortalidad a 12 meses del índice PROFUND y VGS en PP internados en clínica médica. Ingresaron al estudio 111 pacientes. Edad 75.8 (± 9.3) años. índice PROFUND 7.6 (± 4.7) puntos. El 60.1% presentaba desnutrición moderada-severa por VGS. Fallecieron 66 dentro del año. En el modelo de Cox, la VGS y el índice PROFUND se asocian con mortalidad a los 12 meses (p < 0.0001 y p 0.0026 respectivamente). En los desnutridos severos, el riesgo es aproximadamente 6 veces mayor en comparación a los normonutridos (HR: 6.514, IC95% 2.826-15.016) y para un mismo nivel de VGS, el riesgo es un 10% mayor por cada punto que aumenta el índice PROFUND (HR: 1.106, IC95% 1.036-1.181). El AUC para predecir mortalidad a 12 meses del índice PROFUND y VGS fue: 0.747 (IC95%: 0.656-0.838); 0.733 (IC95%: 0.651-0.816) y al combinar las dos variables: 0.788 (IC95%: 0.703-0.872, p 0.048). Como conclusión el índice PROFUND y la VGS se asocian con mortalidad y tienen un valor pronóstico similar. La combinación de ambas herramientas permitiría establecer mejor el pronóstico y el manejo en esta compleja población.

RESUMO

INTRODUCTION: the Nutrition Risk in Critically Ill (NUTRIC) score does not include a variable that objectively estimates protein hypercatabolism (PHC), one of the main metabolic changes experienced by critical patients. OBJECTIVE: to evaluate the correlation of the NUTRIC score with PHC in critically ventilated patients. MATERIALS AND METHODS: prospective, observational study. Mixed ICU. It included ventilated patients ≥ 18 years old, without anuria or chronic renal failure. The modified NUTRIC score, which replaces IL-6 for PCR, was obtained at admission and 24-hour urine was collected at the 2nd (T0) and 4th day (T1) to determine the total urinary nitrogen (TUN). RESULTS: a total of 69 patients were included. Average age: 43 years (± 17.01); 73% were males. Admission pathologies: trauma (39%) and sepsis (20%). APACHE II: 17 (± 6.66). Seventeen patients presented acute renal failure (ARF). NUTRIC score mean: 3.13 (± 1.94); 84% presented low nutritional risk. The Pearson correlation between NUTRIC and TUN in T0 and T1 was: -0.150 (p: 0.218) and -0.053 (p: 0.663). The mean length of staying in ICU and mechanical ventilation was: 13.35 (± 12.37) and 9.84 (± 10.82) days, respectively. Mortality in ICU: 36%. In the non-ARF subgroup with low risk according to NUTRIC score, 27% presented severe PHC at T0 and 52% at T1. The correlation was: 0.070 (p: 0.620) and 0.138 (p: 0.329), respectively. CONCLUSION: no correlation was found between the estimators of the stress metabolic response of the NUTRIC score and the PHC in critically ill patients ventilated; therefore, it would not be possible to substitute the measurement of the same in the assessment of the nutritional risk.


INTRODUCCIÓN: la escala de riesgo nutricional NUTRIC no incluye una variable que estime en forma objetiva el hipercatabolismo proteico (HCP), una de las principales alteraciones metabólicas que experimentan los pacientes críticos. OBJETIVO: evaluar la correlación de la escala NUTRIC con el HCP en pacientes críticos ventilados. MATERIAL Y MÉTODOS: estudio prospectivo, observacional. UCI polivalente. Incluyó pacientes ≥ 18 años, ventilados, sin anuria ni insuficiencia renal crónica. La variante del NUTRIC, que remplaza la IL-6 por PCR se obtuvo al ingreso y se recolectó orina de 24 horas al segundo (T0) y cuarto día (T1) para determinar el nitrógeno urinario total (NUT). RESULTADOS: se incluyeron 69 pacientes. Edad media: 43 años (± 17,01); el 73% eran varones. Patologías de ingreso: trauma (39%) y sepsis (20%). APACHE II: 17 (± 6,66). Presentaron insuficiencia renal aguda (IRA) 17 pacientes. NUTRIC medio: 3,13 (± 1,94). El 84% presentó bajoriesgo nutricional. La correlación de Pearson entre NUTRIC y NUT en T0 y T1 fue de -0,150 (p: 0,218) y -0,053 (p: 0,663). La media de internación y ventilación mecánica fue de 13,35 (± 12,37) y 9,84 (± 10,82) días, respectivamente. Mortalidad en UCI: 36%. En el subgrupo sin IRA con bajo riesgo por NUTRIC el 27% presentó HCP severo en T0 y el 52% en T1. La correlación fue: 0,070 (p: 0,620) y 0,138 (p: 0,329), respectivamente. CONCLUSIÓN: no se halló correlación entre los estimadores de la respuesta metabólica de estrés de la escala NUTRIC y el HCP en pacientes críticos ventilados; por lo tanto, no se podría sustituir la medición real del mismo en la valoración del riesgo nutricional.

RESUMO

INTRODUCTION: Community-acquired pneumonia (CAP) is the infectious disease with the highest number of deaths worldwide. Several studies have shown an association between vitamin D deficiency and increases susceptibility to respiratory tract infections. OBJECTIVE: The aim of this study was to evaluate the serum 25-hydroxyvitamin D (25OHD) levels in hospitalized adults in general room with CAP. MATERIALS AND METHODS: An observational study was carried out in 207 hospitalized adults of both sex with CAP (>18 years) from Rosario city, Argentina (32° 52' 18″S) between July 2015 and June 2016. RESULTS: In total, 167 patients were included in the data analysis [59% women (57.4 ± 19.6 years), body mass index 27.2 ± 7.8 kg/m2 ]. In brief, 63% showed unilobar infiltrate and 37% were multilobar. The CURB-65 index was 66.5% low risk, 16.0% intermediate risk and 17.5% high risk. According to Charlson comorbidity index (CCI) 53.5% had not comorbidity (CCI = 0) and 46.5% showed CCI ≥ 1. The 25OHD level was: 11.92 ± 7.6 ng/mL (51.5%: <10 ng/mL, 33.5%: 10-20 ng/mL, 13.2%: 20-30 ng/mL and 1.8%: >30 ng/mL). Higher 25OHD were found in male (female: 10.8 ± 6.7 ng/mL, male: 13.5 ± 8.5 ng/mL, P = .02) and 25OHD correlated with age (r = -.17; P = .02). 25-Hydroxyvitamin D was also correlated with CURB65 index (r = -.13; P = .049), CCI (r = -.20, P = .007) and with the 10 years of life expectative (%) (r = .19; P = .008). In addition, higher 25OHD were found with lower CCI (CCI 0 = 13.0 ± 8.2 ng/mL, CCI ≥ 1= 10.5 ± 6.7 ng/mL; P = .0093). CONCLUSIONS: Hospitalized adults with CAP have lower 25OHD levels and would be associated with the severity of CAP.

RESUMO

Resumen El índice PROFUND se desarrolló y validó para predecir mortalidad a 12 meses en pacientes pluripatológicos. Sin embargo, su valor potencial para predecir mortalidad intrahospitalaria no ha sido suficientemente estudiado. Se evaluó la capacidad del índice PROFUND en comparación con la proteína C re activa (PCR), la albúmina, y el ancho de distribución eritrocitaria (ADE) para predecir mortalidad intrahospitalaria, mediante el análisis posterior de una cohorte prospectiva de 111 pacientes pluripatológicos internados en clínica médica. La edad promedio fue 75.8 ± 9.3 años. La mortalidad intrahospitalaria fue de 17% (19 pacientes). La mediana (RIQ) del índice PROFUND, albúmina, PCR y ADE en los fallecidos y sobrevivientes fue 12 (4) y 6 (7) p< 0.0001, 2.5 (0.4) y 2.6 (0.8) p 0.295, 58 (64) y 40 (60) p 0.176, 14.5 (2) y 14.6 (3) p 0.523, respectivamente. El análisis logístico multivariado mostró que el índice PROFUND se asocia con mortalidad intrahospitalaria (p 0.0003). El riesgo de fallecer durante la internación es 20% mayor por cada punto que se incrementa el índice PROFUND (OR 1.2, IC95% 1.1-1.4). El área bajo la curva de las características operativas del receptor (AUC-ROC) del índice PROFUND para predecir mortalidad durante la internación (0.760, IC95% 0.628-0.891) fue mayor a la del ADE, PCR y albúmina (0.494 IC95% 0.364-0.624 p 0.012; 0.583 IC95% 0.437-0.728 p 0.028; 0.621 0.494-0.748 p 0.109, respectivamente). El índice PROFUND se asocia a mortalidad intrahospitalaria, con una mayor capacidad predictiva que los biomarcadores estudiados, lo cual se sumaría a su valor pronóstico a largo plazo en pacientes pluripatológicos.


Abstract The PROFUND index was developed and valid to predict mortality at 12 months in polypathological patients (PP). However, its potential value for predicting in-hospital mortality has not been sufficiently studied. The ability of the PROFUND index in comparison with C-reactive protein (CRP), albumin, and red blood cell distribu tion width (RDW) to predict in-hospital mortality was evaluated through the subsequent analysis of a prospective cohort of 111 multiple pathological patients admitted to the clinic medical. The mean age was 75.8 ± 9.3 years. In-hospital mortality was 17% (19 patients). The median (IQR) of the PROFUND index, albumin, CRP and ADE in the deceased and survivors was 12 (4) and 6 (7) p < 0.0001, 2.5 (0.4) and 2.6 (0.8) p 0.295, 58 (64) and 40 (60) p 0.176, 14.5 (2) and 14.6 (3) p 0.523, respectively. The multivariate logistic analysis showed that the PROFUND index is associated with in-hospital mortality (p 0.0003). The risk of dying during hospitalization is 20% higher for each point that the PROFUND index increases (OR 1.2, 95% CI 1.1-1.4). The area under the curve the receiver operating characteristic (AUC-ROC) of the PROFUND index to predict mortality during hospitalization (0.760, 95% CI 0.628-0.891) was higher than that of the RDW, CRP and albumin (0.494 95% CI 0.364-0.624 p 0.012; 0.583 95% CI 0.437-0.728 p 0.028; 0.621 0.494-0.748 p 0.109, respectively). The PROFUND index is associated with in-hospital mortality, with a greater predictive capacity than the biomarkers studied, which would add to its long-term prognostic value in multiple pathological patients.

Abstract The PROFUND index is one of the suggested prognostic scores in pluripathological patients (PP). Despite the prognostic value of malnutrition and its prevalence in this population, it does not include a variable that estimates nutritional status. Subjective global assessment (SGA) is a widely validated tool for this purpose. The prognostic capacity of 12-month mortality of PROFUND index and SGA in PP admitted to a medical clinic was evaluated by a prospective and observational study. 111 patients entered the study. Age 75.8 (± 9.3) years. PROFUND index 7.6 (± 4.7) points. 60.1% had moderate-severe malnutrition due to VGS. 66 died within the year. In the Cox model, SGA and PROFUND index are associated with mortality at 12 months (p <0.0001 and p 0.0026 respectively). In severe malnutrition, the risk is approximately 6 times higher compared to normonutrition (HR: 6.514, 95% CI 2.826-15.016) and for the same level of SGA, the risk is 10% higher for each point that the PROFUND index increases (HR: 1.106, 95% CI 1.036-1.181). The AUC for predicting 12-month mortality from PROFUND index and SGA was: 0.747 (95% CI: 0.656-0.838); 0.733 (95% CI: 0.651-0.816) and when combining the two variables: 0.788 (95% CI: 0.703-0.872, p 0.048). In conclusion, PROFUND index and SGA are associated with mortality and have a similar prognostic value. The combination of both tools would allow better prognosis and management in this complex population.

RESUMO

RESUMEN Objetivo: Estudiar la capacidad discriminativa de hipercatabolismo proteico grave del índice urea/creatinina en orina aislada en pacientes críticos ventilados. Metodos: Estudio prospectivo, observacional. Incluyó 52 pacientes sin insuficiencia renal. Variables: nitrógeno urinario total estimado a partir de la urea en orina de 24 horas al segundo (T1) y cuarto día (T2) e índice urea/creatinina en orina aislada previo a la recolección de orina de 24 horas. Resultados: Presentaron hipercatabolismo proteico grave (nitrógeno urinario total estimado > 15g) 14 pacientes (26,9%) en T1 y 29 (55,7%) en T2. El 84% de los pacientes presentaron bajo riesgo nutricional por la escala Nutrition Risk in the Critically Ill. En el segundo día, la correlación de Pearson del nitrógeno urinario total estimado con el índice urea/creatinina fue: 0,272 (p = 0,051) y en el cuarto día: 0,276 (p = 0,048). El índice urea/creatinina al cuarto día, tuvo una tendencia a mayor discriminación del hipercatabolismo proteico grave que el Acute Physiology and Chronic Health Evaluation II y Nutrition Risk in the Critically Ill (AUC 0,741 versus 0,669 y 0,656, IC95%: 0,602 - 0,880; 0,519 - 0,818 y 0,506 - 0,806 respectivamente). El valor de corte optimo del índice urea/creatinina para diagnóstico de hipercatabolismo proteico grave fue de 16,15 con una sensibilidad de 79,31% (IC95%: 59,74 - 91,29), especificidad de 60,87% (IC95%: 38,78 - 79,53), valor predictivo positivo 71,88% (IC95%: 53,02 - 85,60), valor predictivo negativo 70,0% (IC95%: 45,67 - 87,18), LR (+) 2,03 (IC95%: 1,18 - 3,49) y LR (-) 0,34 (IC95%: 0,16 - 0,74). Conclusión: El índice urea/creatinina realizado al cuarto día tiene un discreto valor para estimar el hipercatabolismo proteico grave por nitrógeno urinario total y no reemplaza al mismo en pacientes críticos ventilados sin falla renal. Por su razonable sensibilidad podría ser utilizado como cribado para identificar a quien tomar la muestra de orina de 24 horas.


ABSTRACT Objective: To study the ability of the urea/creatinine index to identify severe protein catabolism from the isolated urine of critically ventilated patients. Methods: This was a prospective, observational study. It included 52 patients without kidney failure. Variables: total urinary nitrogen estimated from the urea in 24-hour urine on the second (T1) and fourth days (T2) and urea/creatinine index in isolated urine before 24-hour urine collection. Results: Severe protein hypercatabolism (estimated total urinary nitrogen > 15g) was present in 14 patients (26.9%) at T1 and in 29 (55.7%) at T2. Eighty-four percent of patients had low nutritional risk by the Nutrition Risk in the Critically Ill score. At T1, the Pearson correlation between the estimated total urinary nitrogen and the urea/creatinine index was 0.272 (p = 0.051), and at T2 it was 0.276 (p = 0.048). The urea/creatinine index at T2 had a tendency to better discriminate severe protein hypercatabolism than Acute Physiology and Chronic Health Evaluation II and Nutrition Risk in the Critically Ill (AUC 0.741 versus 0.669 and 0.656, 95%CI: 0.602 - 0.880; 0.519 - 0.818 and 0.506 - 0.806, respectively). The optimal cutoff value of the urea/creatinine index for the diagnosis of severe protein hypercatabolism was 16.15, with a sensitivity of 79.31% (95%CI: 59.74 - 91.29), specificity of 60.87% (95%CI: 38.78 - 79.53), positive predictive value 71.88% (95%CI: 53.02 - 85.60), negative predictive value 70.0% (95%CI: 45.67 - 87.18), LR (+) 2.03 (95%CI: 1.18 - 3.49), and LR (-) 0.34 (95%CI: 0.16 - 0.74). Conclusion: The urea/creatinine index measured on the fourth day has a certain ability to estimate severe protein hypercatabolism (as defined by estimated total urinary nitrogen) but does not replace total urinary nitrogen in critically ventilated patients without kidney failure. Due to its reasonable sensitivity, it could be used as a screen to identify which patients to take a 24-hour urine sample from.

RESUMO

INTRODUCTION: The NUTRIC score was proposed to assess the risk of adverse events potentially modifiable through nutritional intervention in critically ill patients. This score uses interleukin-6 (IL-6), a biomarker not always available. OBJECTIVE: To study two variants of the score in patients with assisted mechanical ventilation (AMV): NUTRIC-1 without IL-6 and NUTRIC-2 with CRP as biomarker. METHODS: Observational prospective cohort with 368 patients with AMV >24 hours. The predictive capacity of both NUTRIC scores was studied by binary logistic regression. The significance level was set at 5%. RESULTS: mean age, 52 years; males 68%. Mean APACHE II score: 20.73 points. Death at the ICU: 196 (53%). Mean time on AMV of the survivals: 8.55 days. Mean NUTRIC-1 and NUTRIC-2 in the deceased-survivors: 4.23 - 3.06 (p = 0.000) and 4.68 -3.39 (p = 0.000). The mortality increased in relation to the score (p = 0.000). The calculated AUC for NUTRIC-1 and NUTRIC-2 were 0.671 (CI 0.617-0.726) and 0.679 (CI 0.624- 0.733). The mean CRP was higher in deceased patients: 13.07 mg/dL - 8.97 mg/dL (p = 0.001), the correlation improved with more days on AMV (p = 0.034 and p = 0.010) and the AUC increased in a similar way to IL-6 in the original work (0.008 and 0.007, respectively). CONCLUSION: The two studied variants of the NUTRIC score behaved similarly to the original NUTRIC score. The addition of the CRP improves the score performance and may be an alternative to IL-6, if it is not available.

RESUMO

La púrpura de Schönlein-Henoch (PSH) es una vasculitis de pequeños vasos con depósito de inmunocomplejos de IgA. La presentación en adultos es rara y grave. Los casos comunicados de PSH en pacientes infectados por HIV son escasos. Los anticuerpos anticitoplasma de neutrófilos (ANCA), detectados por inmunofluorescencia indirecta (IFI), se encuentran comúnmente en otras vasculitis sistémicas primarias pero rara vez en PSH y es aún más inusual el patrón perinuclear (ANCA-p). Por otra parte, la positividad de los ANCA puede ser detectada en una serie de condiciones patológicas distintas de las vasculitis de pequeños vasos en asociación a procesos infecciosos, incluyendo el HIV, o a consumo de cocaína, y en especial el patrón de ANCA-p vinculado a medicamentos o enfermedades autoinmunes e inflamatorias intestinales. Se presenta el caso de un varón de 35 años con hábitos tóxicos (cocaína, marihuana) que consultó por dolor abdominal, hematoquecia y lesiones purpúricas en extremidades inferiores, que agregó fiebre, artralgias y progresión de lesiones purpúricas asociadas a síndrome nefrítico y ANCA-p (+). Durante la internación se detectó infección por HIV. La biopsia renal evidenció una nefropatía a IgA que tuvo una respuesta favorable al tratamiento corticoideo y antiproteinúrico. La comunicación del caso obedece a la rareza de la presentación y a la complejidad para establecer el diagnóstico y la terapéutica. Aún resta dilucidar el rol de los ANCA en la etiopatogenia y el manejo de la PSH del adulto.


The Henoch-Schönlein purpura (HSP) is a small vessel vasculitis with IgA immune complex deposition. The presentation in adults is rare and severe. Reported cases of HSP in patients infected with HIV are scarce. Neutrophil cytoplasmic antibodies (ANCA) are commonly found in other systemic vasculitis, but rarely in HSP and even more unusual the perinuclear pattern. Beside small vessel vasculitis, positivity of ANCA can be detected in a number of different pathological conditions in association with infectious processes, including HIV, or cocaine use, and especially the pattern of ANCA-p, associated with drugs, inflammatory bowel or autoimmune diseases. We report the case of a 35 years old man with toxic habits (cocaine, marijuana) who consulted for abdominal pain, hematochezia and purpura on lower extremities, and later fever, joint pain and progression of purpura associated with nephritic syndrome and ANCA-p (+). During hospitalization HIV infection was detected. Renal biopsy showed IgA nephropathy with favorable response to corticosteroid and antiproteinuric treatment. The communication of the case is due to the rarity of the presentation and therapeutic diagnostic challenge. It remains to elucidate the role of ANCA in the pathogenesis and management of adult PSH.
