RESUMO

Introduction: Introduction: to explore the effect of individualized nutritional intervention on the nutritional status of patients with liver cancer after transcatheter arterial chemoembolization (TACE). Methods: 56 patients who underwent TACE in our hospital from March 2022 to March 2023 were selected as the study subjects. The patients were randomly divided into a control group (28 cases) and an intervention group (28 cases). The control group received routine dietary intervention, while the intervention group received individualized nutritional intervention. We analyzed the body mass index (BMI), nutritional risk screening 2002 (NRS 2002), nutritional status, liver function status, and incidence of complications in two groups of patients before TACE, 3 days after TACE, and 1 month after TACE. Results: on the third day after TACE, the nutritional related indicators of both groups of patients showed a significantly decrease compared to those before TACE (p < 0.05), while the majority of liver function indicators significantly increased (p < 0.05). Compared with those at 3 days after TACE, the nutritional status of the intervention group patients significantly improved (p < 0.05) and liver function indicators significantly decreased (p < 0.05) 1 month after TACE. One month after TACE, all nutritional indicators in the intervention group were significantly higher than those in the control group (p < 0.05), and AST was significantly lower than that in the control group (p < 0.05). The incidence of gastrointestinal complications and electrolyte disorders in the intervention group were significantly lower than that in the control group (p < 0.05). Conclusion Individualized nutritional intervention can effectively improve nutritional status, improve liver function, and reduce the incidence of postoperative complications in liver cancer patients after TACE. It was worth promoting.


Introducción: Introducción: explorar el efecto de la intervención nutricional individualizada sobre el estado nutricional de los pacientes con cáncer de hígado después de la quimioembolización arterial (TACE). Métodos: se seleccionaron como sujetos de estudio 56 pacientes sometidos a TACE en nuestro hospital entre marzo de 2022 y marzo de 2023. Los pacientes se dividieron aleatoriamente en un grupo de control (28 casos) y un grupo de intervención (28 casos). El grupo de control recibió una intervención dietética rutinaria, mientras que el grupo de intervención recibió una intervención nutricional individualizada. Se analizó el índice de masa corporal (IMC), el cribado del riesgo nutricional 2002 (NRS 2002), el estado nutricional, el estado de la función hepática y la incidencia de complicaciones en dos grupos de pacientes antes de la TACE, 3 días después de la TACE y 1 mes después de la TACE. Resultados: al tercer día después de la TACE, los indicadores relacionados con la nutrición de ambos grupos de pacientes mostraron una disminución significativa en comparación con los de antes de la TACE (p < 0.05), mientras que la mayoría de los indicadores de la función hepática aumentaron significativamente (p < 0.05). En comparación con los 3 días después de la TACE, el estado nutricional de los pacientes del grupo de intervención mejoró significativamente (p < 0.05) y los indicadores de la función hepática disminuyeron significativamente (p < 0.05) 1 mes después de la TACE. Un mes después de la TACE, todos los indicadores nutricionales del grupo de intervención fueron significativamente superiores a los del grupo de control (p < 0.05), y la AST fue significativamente inferior a la del grupo de control (p < 0.05). La incidencia de complicaciones gastrointestinales y trastornos electrolíticos en el grupo de intervención fue significativamente inferior a la del grupo de control (p < 0.05). Conclusión: la intervención nutricional individualizada puede mejorar eficazmente el estado nutricional, mejorar la función hepática y reducir la incidencia de complicaciones postoperatorias en pacientes con cáncer de hígado tras TACE. Merece la pena promoverlo.

RESUMO

Introducción: las enzimas y marcadores del perfil hepático permiten evaluar la funcionalidad y condición del hígado. Sus elevaciones pueden ser silentes y con cierta prevalencia en muchos adultos. Objetivo: determinar las principales alteraciones en el hepatograma en pacientes que acuden a consulta médica de rutina. Metodología: estudio descriptivo, prospectivo y transversal realizado a partir de resultados de laboratorio de historias clínicas de 364 pacientes de todas las edades y ambos sexos pertenecientes a un policlínico del distrito de Villa el Salvador, Perú desde enero de 2021 a julio de 2022. Las variables fueron: edad, sexo, valores de transaminasa glutámico pirúvica (TGP), transaminasa glutámico oxalacética (TGO), bilirrubina directa, indirecta y total, albúmina, globulinas y fosfatasa alcalina (FA). Resultados: en el promedio total de la muestra, la TGP fue alta (51,05 U/L), así como la bilirrubina total (1,50 mg/dL) y la FA (135,84 U/L). La TGP fue alta en hombres (54,92 U/L) y mujeres (48,86 U/L). La TGO fue normal en mujeres y alta en hombres (48,24 U/L). La bilirrubina indirecta fue alta en hombres (1,33 mg/dL). La FA fue más alta en ambos sexos (143,28 U/L en hombres y 126,38 en mujeres). Según grupo etario, los valores de TGO fueron más altos en el grupo de edad igual o mayor a 40 años (49,99 U/L). Los valores de TGP fueron elevados en ambos sexos (55,96 U/L en hombres y 50,90 U/L en mujeres), así como en la bilirrubina total, la que fue más alta en el grupo de edad igual o mayor a 40 años (2,03 mg/dL). La bilirrubina indirecta, albúmina y FA fueron normales en el grupo de edad igual o menor de 39 años, pero fueron elevadas en el grupo de edad igual o mayor a 40 años (1,13 mg/dL, 5,77 gr/dL y 147,95 U/L, respectivamente). Conclusiones: existen alteraciones en el perfil hepático en pacientes asintomáticos en la muestra estudiada. A pesar de no ser elevaciones significativamente grandes, se recomienda identificar y tratar las posibles causas que pudieran desencadenar dichas elevaciones, así como la realización de más estudios similares a nivel nacional para caracterizar el perfil hepático de nuestra población.


Introduction: The enzymes and markers of the liver profile allow us to evaluate the functionality and condition of the liver. Their elevations may be silent and have a certain prevalence in many adults. Objective: To determine the main alterations in the hepatogram in patients who attend routine medical consultation. Methodology: Descriptive, prospective and cross-sectional study carried out based on laboratory results from medical records of 364 female and male patients of all ages attending a polyclinic in the district of Villa El Salvador, Peru from January 2021 to July 2022. The variables were: age, sex, values ​​of alanine aminotransferase (ALT), aspartate transaminase (AST), direct, indirect and total bilirubin, albumin, globulins and alkaline phosphatase (ALP). Results: In the total average of the sample, ALT was high (51.05 U/L), as well as total bilirubin (1.50 mg/dL) and ALP (135.84 U/L). ALT was high in men (54.92 U/L) and women (48.86 U/L) while AST was normal in women and high in men (48.24 U/L). Indirect bilirubin was high in men (1.33 mg/dL) and ALP was higher in both sexes (143.28 U/L in men and 126.38 in women). According to age group, AST values ​​were highest in the age group equal to or greater than 40 years (49.99 U/L). ALT values ​​were high in both sexes (55.96 U/L in men and 50.90 U/L in women), as well as total bilirubin, which was highest in the age group equal to or greater than 40 years (2.03 mg/dL). Indirect bilirubin, albumin and ALP were normal in the age group equal to or less than 39 years, but were elevated in the age group equal to or greater than 40 years (1.13 mg/dL, 5.77 gr/dL and 147.95 U/L, respectively). Conclusions: There are alterations in the liver profile of asymptomatic patients in the sample studied. Although they are not significantly large elevations, it is recommended to identify and treat the possible causes that could trigger these elevations, as well as carrying out more similar studies at a national level to characterize the liver profile of our population.

RESUMO

Vários estudos sugerem a importância da vitamina D ­ 25(OH)D ­ na evolução clínica dos pacientes com malária. Entretanto, a prevalência de deficiência de 25(OH)D na população amazônica é pouco conhecida, havendo também poucos estudos com pacientes diagnosticados com malária. Assim, o objetivo deste estudo foi avaliar os níveis séricos de 25(OH)D em pacientes com malária e sua relação com dados epidemiológicos, parasitológico e provas de função hepática. Para tanto, foi realizado um estudo transversal analítico com um grupo de pacientes com malária e um grupo controle no município de Itaituba (PA), Brasil, no período de janeiro de 2018 a outubro de 2019. Elaborou-se um protocolo para avaliação dos dados sociodemográficos, parasitológicos e laboratoriais, adotando-se o nível de significância de 5%. A prevalência de deficiência de 25(OH)D foi observada nos pacientes com malária (28,5%) e no grupo controle (24,6%), sem diferença estatística; porém, entre os residentes no garimpo, os níveis séricos foram estatisticamente menores nos pacientes com malária. Os níveis séricos de transaminase glutâmico-pirúvica (TGP) apresentaram correlação inversa com os de 25(OH)D. As provas de função hepática foram significativamente maiores no grupo com malária. Dessa forma, este estudo evidenciou a deficiência de 25(OH)D em Itaituba. Alterações hepáticas pela infecção plasmodial podem ter contribuído para a correlação inversa observada entre os níveis de TGP e 25(OH)D.


Several studies suggest the importance of vitamin D ­ 25(OH)D ­ in the clinical evolution of patients with malaria. However, the prevalence of 25(OH)D deficiency in the Amazonian population is little known, and studies with patients diagnosed with malaria are scarce. Thus the objective of this study is to evaluate the serum levels of 25(OH)D in patients with malaria and its relationship with epidemiological and parasitological data and liver function tests. To that end, an analytical cross-sectional study was carried out with a group of patients with malaria and a control group in the municipality of Itaituba (PA), Brazil, from January 2018 to October 2019. A protocol was elaborated for the evaluation of sociodemographic, parasitological, and laboratory data, adopting a significance level of 5%. Results: The prevalence of 25(OH)D deficiency was observed in patients with malaria (28.5%) and in the control group (24.6%), with no statistical difference; however, among residents in the mining, serum levels were statistically lower in patients with malaria. The glutamic-pyruvic transaminase (GPT) serum levels showed an inverse correlation with 25(OH)D levels. Liver function tests were significantly higher in the malaria group. Thus, this study evidenced 25(OH)D deficiency in Itaituba. Hepatic changes due to plasmodial infection may have contributed to the inverse correlation observed between GPT and 25(OH)D levels.


Diversos estudios sugieren la importancia de la vitamina D ­[25(OH)D]­ en la evolución clínica de pacientes con malaria. Sin embargo, la prevalencia de la deficiencia de 25(OH)D en la población amazónica es poco conocida y existen pocos estudios en pacientes con malaria. Ante esto, el objetivo de este estudio fue evaluar los niveles séricos de 25(OH)D en pacientes con malaria y su relación con datos epidemiológicos, parasitológicos y pruebas de función hepática. Para ello, se realizó un estudio transversal analítico en el grupo de pacientes con malaria y en un grupo control en el municipio de Itaituba (PA), Brasil, de enero de 2018 a octubre de 2019. Se elaboró un protocolo para la evaluación de datos sociodemográficos, parasitológicos y de laboratorio, adoptando un nivel de significancia del 5%. La prevalencia de deficiencia de 25(OH)D se observó en pacientes con malaria (28,5%) y en el grupo control (24,6%), sin diferencia estadística; sin embargo, entre los residentes en la minería, los niveles séricos fueron estadísticamente inferiores en pacientes con malaria. Los niveles séricos de transaminasa glutámico pirúvica (TGP) mostraron una correlación inversa con los niveles de 25(OH)D. Las pruebas de función hepática fueron significativamente más altas en el grupo de malaria. De esta manera, se evidenció deficiencia de 25(OH)D en la población de Itaituba. Los cambios hepáticos debido a la infección plasmodial pueden haber contribuido a la correlación inversa observada entre los niveles de TGP y 25(OH)D.

RESUMO

PURPOSE: Clinically significant portal hypertension (CSPH), although not a contraindication for liver resection in cirrhosis, is considered a determinant prognostic factor for post-surgical outcomes. This study aims to investigate the effects of CSPH on short and long-term results after hepatic resection for hepatocellular carcinoma (HCC). METHODS: Single-center retrospective analysis of 126 consecutive hepatic resections for HCC in Child-Pugh A patients, performed between 2008 and 2018. Patients were divided according to the presence of CSPH, defined as a hepatic venous pressure gradient ≥ 10 mmHg. To overcome selection bias, 42 patients with CSPH were matched through propensity score with 42 patients without CSPH. Intraoperative and post-operative outcomes, along with overall and disease-free survival, were compared between the matched groups. RESULTS: Liver decompensation was four-fold in the CSPH group (28.6% vs. 7.1%, p = 0.010), while rate of severe complications, including 90-days mortality, was not statistically different between patients with and without CSPH. Overall and recurrence-free survival was not inferior in patients with CSPH compared to non-CSPH group. CONCLUSIONS: The present study has demonstrated acceptable outcomes of liver resection for HCC in carefully selected Child-Pugh A cirrhotic patients, even in the presence of elevated portal pressure.


OBJETIVOS: La hipertensión portal clínicamente significativa (HPCS), si bien no representa una contraindicación para la resección hepática en la cirrosis, se considera un factor pronóstico determinante en los resultados posoperatorios. Este estudio se propone de estudiar los efectos de la HPCS en los resultados a corto y largo plazo tras la resección hepática por carcinoma hepatocelular (CHC). MÉTODOS: Análisis retrospectivo mono-céntrico de 126 resecciones hepáticas por CHC en pacientes Child-Pugh A, realizadas entre el 2008 y el 2018. Los pacientes se han dividido según la presencia de HPCS, definida como gradiente de presión venoso hepático ≥ 10 mmHg. Para controlar el sesgo de selección, 42 pacientes con HPCS se han apareado con puntaje de propensión con 42 pacientes sin HPCS. RESULTADOS: La tasa de descompensación hepática fue 4 veces superior en los pacientes con HPCS (28.6% vs. 7.1%, p = 0.010), mientras las complicaciones graves, incluyendo la mortalidad a 90 días, no se mostraron diferentes en los pacientes con y sin HPCS. La supervivencia global y libre de recidiva no fueron inferiores en los pacientes con HPCS comparados. CONCLUSIONES: El presente estudio ha demostrado resultados aceptables en la resección hepática en pacientes con cirrosis Child-Pugh A cuidadosamente seleccionados, también en presencia de hipertensión portal.

RESUMO

OBJECTIVE: This study aims to investigate the relationship between the pre-operative indocyanine green (ICG) test, the chemotherapy-associated liver injury (CALI), and the development of severe post-operative complications (POC) in patients operated of colorectal liver metastases (CRLMs). MATERIALS AND METHODS: Sixty-nine patients previously treated with chemotherapy and submitted to liver resection for CRLM were retrospectively studied. Two pathologists independently reviewed the pathological specimens and assessed the presence of CALI. The correlation between ICG clearance and specific pathological features was analyzed. In addition, a logistic regression analysis was performed to seek for pre-operative factors associated with severe complications. RESULTS: After a mean of 10.6 (± 7.5) chemotherapy cycles, 44 patients (63.8%) developed CALI. ICG retention rate at 15 min (ICG-R15) was not statistically different between patients with and without CALI and it could only discriminate the presence of centrilobular fibrosis. Rate of severe complications was almost 6-fold in patients with CALI compared to patients without CALI (p = 0.024). ICG-R15 ≥ 10% was the only independent risk factor associated with severe POC at multivariable logistic regression (OR = 4.075 95% CI: 1.077-15.422, p = 0.039). CONCLUSIONS: Pre-operative ICG clearance test, although not useful to identify patients with hepatic drug toxicity, is a strong predictor for the development of severe post-hepatectomy complications.


OBJETIVO: Investigar la relación entre el test de aclaramiento del verde de indocianina (ICG) preoperatorio, las alteraciones patológicas derivadas de la quimioterapia (CALI) y el desarrollo de complicaciones posoperatorias en los pacientes sometidos a resección hepática por metástasis de cáncer colorrectal (MCCR). MATERIAL Y MÉTODOS: Sesenta y nueve pacientes previamente tratados con quimioterapia y operados de MCCR se estudiaron de manera retrospectiva. Dos patólogas revisaron independientemente el parénquima hepático no tumoral de los especímenes y determinaron la presencia de daño quimio-inducido. Se analizó la correlación entre el aclaramiento de ICG y las diferentes alteraciones anatomo-patológicas encontradas. Además, se realizó un análisis de regresión logística para identificar los factores preoperatorios asociados con las complicaciones posoperatorias. RESULTADOS: Tras una media de 10.6 (± 7.5) ciclos de quimioterapia, 44 pacientes (63.8%) desarrollaron CALI. La tasa de retención de ICG a los 15 minutos (ICG-R15) no fue estadísticamente diferente entre los pacientes con y sin CALI y solo pudo discriminar la presencia de fibrosis centrolobulillar. La tasa de complicaciones severas posoperatorias fue 6 veces superior en los pacientes con CALI, comparada con aquella de los pacientes sin CALI (p = 0.024). Un ICG-R15 ≥ 10% fue el único factor de riesgo independiente asociado a complicaciones severas (OR = 4.075 95% CI: 1.077-15.422, p = 0.039). CONCLUSIONES: La prueba preoperatoria de aclaramiento del ICG, a pesar de no identificar eficazmente los pacientes con daño por quimioterapia, es un fuerte predictor de desarrollo de complicaciones severas posoperatorias.

RESUMO

Abstract Introduction: Estimating and monitoring changes in liver function tests is necessary to prevent the occurrence of chronic liver disease in HIV patients undergoing highly active antiretroviral therapy (HAART). Objective: To determine the variation liver profile test levels in HIV patients undergoing HAART. Materials and methods: Retrospective longitudinal study conducted in 100 HIV patients treated at the Hospital Nacional Hipólito Unanue, Lima, Peru, between 2015 and 2017. Patients in all stages of clinical infection under HAART and with liver function panel results for alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and total protein (TP) were included. Three follow-up liver function tests (every 3 months) were performed while undergoing HAART and participants were categorized as having normal or elevated levels for all liver markers. Differences between the samples analyzed were determined using the paired-samples T test, with a 95% confidence interval and a significance level of p<0.05. Results: Participants' mean age was 33±9.56 years and 67% were male. Mean serum AST, ALT and ALP values decreased between the first and the third measurement (p=0.021, p=0.076 and p=0.002, respectively). No significant differences in GGT and TP levels were observed between the three measurements, nor between patients with normal and elevated AST, ALT, ALP and TP values, but significant differences were observed for GGT (p=0.010). Conclusions: Variations in liver marker levels were observed in all participants, with a decreasing trend in AST, ALT and ALP between the early and late stages of HAART, implying that this therapy could play a role in liver tissue damage.


Resumen Introducción. Para prevenir el desarrollo de enfermedad hepática crónica en pacientes con VIH, durante la terapia antirretroviral de gran actividad (TARGA) se deben estimar y monitorear cambios en el perfil hepático. Objetivo. Determinar la variación de las concentraciones del perfil hepático en pacientes con VIH durante la TARGA. Materiales y métodos. Estudio retrospectivo longitudinal realizado en 100 pacientes con VIH atendidos en el Hospital Nacional Hipólito Unanue, Lima, Perú, entre 2015 y 2017. Se incluyeron pacientes en todos los estadios de infección clínica que estuvieran recibiendo TARGA y en los que se contara con resultados del perfil hepático para alanina aminotransferasa (ALT), aspartato aminotransferasa (AST), fosfatasa alcalina (FA), gammaglutamiltranspeptidasa (GGT) y proteínas totales (PT). Se realizaron tres análisis de control de la función hepática durante la TARGA (1 cada 3 meses) y los participantes se agruparon en niveles normales y elevados para todos los marcadores hepáticos. Las diferencias entre las muestras analizadas fueron determinadas mediante la prueba t-Student para muestras relacionadas, con un intervalo de confianza de 95% y un nivel de significancia de p<0.05. Resultados. La edad promedio fue de 33±9.56 años y el 67% fueron varones. Los valores séricos promedio de AST, ALT y FA disminuyeron entre la primera y la tercera medición (p=0.021, p=0.076 y p=0.002, respectivamente). No se observaron diferencias significativas en los niveles de GGT y PT entre las tres mediciones, ni entre los pacientes con valores normales y elevados para AST, ALT, FA y PT, pero sí para GGT (p=0.010). Conclusiones. Se observaron variaciones en los niveles de los marcadores hepáticos de todos los participantes, con una tendencia a la reducción en AST, ALT y FA entre las etapas iniciales y finales de la terapia, lo que implica que la TARGA podría ejercer un rol en el daño tisular hepático.

RESUMO

Resumen Introducción: En marzo de 2020, la Organización Mundial de la Salud (OMS) decretó la pandemia de la enfermedad por coronavirus de 2019 (COVID-19), que consiste en la infección por coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2). Este virus utiliza la enzima convertidora de angiotensina II (ECA-II) como receptor celular humano, que está presente en el tejido pulmonar, cardíaco, gastrointestinal, hepático, renal y vascular, lo que configura un potencial de afectación multisistémica por parte del patógeno. El hígado puede resultar dañado tanto por la liberación excesiva de citocinas inflamatorias en COVID-19 como por la adopción de fármacos con potencial hepatotóxico en el tratamiento de sus síntomas. Objetivo: analizar la relación entre los cambios en la función hepática causados por el SARS-CoV-2 y su impacto en el pronóstico del paciente. Métodos: el presente estudio consiste en una revisión sistemática, realizada a partir de estudios seleccionados de las bases de datos PMC, LILACS y SciELO. Después de aplicar los criterios de inclusión y exclusión, se definieron 30 artículos para componer la base de datos de este estudio. Resultados: La enzima aspartato-aminotransferasa (AST) estaba aumentando en mayor prevalencia, con un total de 4695 casos, mientras que la alanina-aminotransferasa (ALT) estaba elevada en 3226 casos. Se observa que los pacientes que presentaban síntomas digestivos tenían más probabilidades de presentar daño hepatocelular y, en consecuencia, alteraciones enzimáticas. Además, la mortalidad ocurrió en el 28,9 % de los casos de pacientes con función hepática alterada, mientras que, en aquellos con función normal, esta tasa fue del 9 %. Conclusión: es evidente que existe una relación entre la afectación hepática por COVID-19 y su mortalidad. Sin embargo, todavía existe una limitación en la cantidad y, principalmente, en la homogeneidad de los estudios que realizaron dicha valoración.


Abstract Introduction: In March 2020, the World Health Organization declared COVID-19, a disease caused by SARS-CoV-2 infection, a global pandemic. This virus uses human angiotensin-converting enzyme 2 (ACE2) as its receptor for entry. ACE2 is found in pulmonary, cardiac, gastrointestinal, hepatic, renal and vascular tissues, thus posing a potential risk for multisystemic involvement. The excessive release of inflammatory cytokines in COVID-19, as well as the use of medicines with hepatotoxic potential for the treatment of its symptoms, can damage the liver. Objective: To analyze the relationship between changes in liver function tests caused by SARS-CoV-2 infection and their impact on patient prognosis. Methodology: This is a systematic review of studies selected from the PMC, LILACS and SciELO databases. After applying the inclusion and exclusion criteria, 30 articles were included in the final sample for analysis. Results: Elevated AST (aspartate aminotransferase) enzyme levels were reported most frequently and were found in 4 695 cases, while ALT (alanine aminotransferase) elevation was described in 3 226 cases. It was observed that patients with digestive symptoms were more likely to present hepatocellular damage and, consequently, enzymatic alterations. Furthermore, 28.9 % of individuals with impaired liver function died, compared to 9 % of patients with normal function. Conclusion: It is evident that there is a relationship between liver involvement in COVID-19 and mortality. However, there is still a limitation in the number and, more importantly, the homogeneity of the research that performed this assessment.

RESUMO

INTRODUCTION: Although changes in liver function tests can be non-specific in numerous clinical conditions, they can be the first sign of a potentially serious disease in an asymptomatic patient. MATERIAL AND METHODS: Retrospective cohort study, performed by reviewing the records of children of a reference hospital central laboratory with alanine aminotransferase enzyme (ALT) elevation during a 6-month aleatory period. RESULTS: 572 blood tests with serum ALT elevation corresponding to 403 patients have been assessed during the period studied. 98 patients were excluded for presenting abnormal liver test before the study period of comorbidity that could produce ALT elevation. The remaining 305 patients, 22.6% were diagnosed with a medical condition during the first blood test that explained the ALT elevation, although only 33.3% of them were followed up until verifying their normalisation. Final study sample consists of 236 patients with abnormal liver test without apparent liver disease. Adequate follow-up was found only in 29% of them. From this group, 9 patients (13%) were diagnosed with liver disease. The rest of the samples were not properly monitored. In patients with higher serum ALT levels, follow-up was early and more appropriate. CONCLUSIONS: In our area, most children without apparent liver disease are no properly monitored. Therefore, an opportunity to diagnosis and treat a potential liver disease was lost in a great number of children. All children with unexplained hypertransaminasaemia must be studied.

RESUMO

Introducción: Las alteraciones del perfil hepático constituyen un hecho inespecífico propio de numerosas condiciones clínicas. Sin embargo, puede implicar la primera manifestación de una patología potencialmente grave en un paciente asintomático.Material y métodos: Estudio observacional retrospectivo que incluye todas las analíticas sanguíneas con elevación de alanino aminotransferasa (ALT) en pacientes pediátricos solicitadas en un sector sanitario en un período de 6meses.Resultados: Se registraron 572 analíticas correspondientes a 403 pacientes. Se excluyeron 98 pacientes con hipertransaminasemia ya conocida o comorbilidad. De los 305 restantes, el 22,6% se diagnosticaron de patología asociada a hipertransaminasemia, y de estos, se comprobó normalización en el 33,3%. De los 236 pacientes con hipertransaminasemia sin justificar se realizó un seguimiento en el 29%, encontrando patología hepática en 9pacientes (13% del grupo). En el resto de la muestra no se comprobó analíticamente la evolución de las transaminasas ni la presencia de posible patología hepática. Los pacientes con cifras más elevadas se controlan mejor y antes que los que presentan cifras más bajas.Conclusiones: En nuestra área, la mayoría de los niños sin enfermedad hepática aparente con hallazgo de ALT elevada no son adecuadamente controlados. Esto hace que se pierda una oportunidad única de diagnosticar y tratar precozmente una enfermedad hepática potencial en un gran número de niños. Todo niño con hipertransaminasemia inexplicada debe ser estudiado. (AU)


Introduction: Although changes in liver function tests can be non-specific in numerous clinical conditions, they can be the first sign of a potentially serious disease in an asymptomatic patient.Material and methods: Retrospective cohort study, performed by reviewing the records of children of a reference hospital central laboratory with alanine aminorransferase enzyme (ALT) elevation during a 6 month aleatory period.Results: 572 blood tests with serum ALT elevation corresponding to 403 patients had been assessed during the period studied. 98 patients were excluded for presenting abnormal liver test before the study period of comorbidity that could produce ALT elevation. The remaining 305 patients, 22.6% were diagnosed with a medical condition during the first blood test that explained the ALT elevation, although only 33.3% of them were followed up until verifying their normalization. Final study sample consists of 236 patients with abnormal liver test without apparent liver disease. Adequate follow-up was found only in 29% of them. From this group, 9 patients (13%) were diagnosed with liver disease. The rest of the sample were not properly monitored. In patients with higher serum ALT levels, follow-up was early and more appropiate.Conclusions: In our area, most children without apparent liver disease are no properly monitored. Therefore, an opportunity to diagnosis and treat a potential liver disease was lost in a great number of children. All children with unexplainedhypertransaminasaemia must be studied. (AU)

RESUMO

OBJECTIVE: To explore the behavior of C-reactive protein (CRP) after orthotopic liver transplantation (OLT) during the first postoperative days, and its usefulness as a marker of severe early allograft dysfunction (EAD). DESIGN: A prospective, single-center cohort study was carried out. SETTING: The Intensive Care Unit (ICU) of a regional hospital with a liver transplant program since 1997. PATIENTS: The study comprised a total of 183 patients admitted to our ICU immediately after liver transplantation between 2009 and 2015. VARIABLES OF INTEREST: C-reactive protein levels upon ICU admission and after 24 and 48h, severe EAD and hospital mortality. RESULTS: The CRP levels after OLT were: upon ICU admission 57.5 (51.6-63.3)mg/L, after 24h 80.1 (72.9-87.3)mg/L and after 48h 69.9 (62.5-77.4)mg/L. Severe EAD patients (14.2%) had higher mortality (23.1 vs 2.5; OR 11.48: 2.98-44.19) and lower CRP upon ICU admission (39.3 [29.8-48.7]mg/L) than the patients without EAD (0.5 [53.9-67.0]; p<0.05] - the best cut-off point being 68mg/L (sensitivity 92.3%; specificity 40.1%; Youden index 0.33). Lower CRP upon ICU admission was correlated to higher mortality (24.5 [9.2-39.7] vs 59.4 [53.4-65.4]; p<0.01, AUC 0.79 [0.65-0.92]). CONCLUSION: Liver transplant is a strong inflammatory stimulus accompanied by high levels of C-reactive protein. A blunted rise in CRP on the first postoperative day after OLT may be a marker of poor allograft function and is related to hospital mortality.

RESUMO

La terapia de la tuberculosis con el esquema 2RHZE/4HE comprende la administración durante seis meses de rifampicina, isoniazida, pirazinamida y etambutol, de las cuales las tres primeras son potencialmente hepatotoxicas y excepcionalmente nefrotoxicas. La tuberculosis produce depleción de la concentración de zinc lo que incrementa la susceptibilidad a la cronicidad de la infección. OBJETIVO: evaluar el efecto de la administración conjunta de zinc y la terapia 2RHZE/4HE sobre la función hepática y renal en pacientes con tuberculosis pulmonar. MÉTODOS: estudio descriptivo de tipo caso control, doble ciego aleatorizado con 22 pacientes con tuberculosis pulmonar en terapia farmacológica y 22 controles sanos reclutados en los centros de salud Sebastián pagador y Alalay. Los pacientes fueron divididos aleatoriamente en dos grupos a los que se les administró zinc (45mg/día) o placebo durante tres meses. En todos los pacientes se tomó muestras de sangre antes y después de la intervención para medir pruebas de función renal y hepática. En los sujetos control la muestra de sangre se tomó al inicio del estudio para realizar las mismas determinaciones. RESULTADOS: no se encontró deferencias en la concentración de marcadores específicos de daño hepático o renal. CONCLUSIONES: la adición de un suplemento diario de 45mgr de zinc a la terapia 2RHZE/4HE no produjo daño renal ni hepático en las personas evaluadas.


Tuberculosis therapy with the 2RHZE / 4HE scheme comprises the administration for six months of rifampin, isoniazid, pyrazinamide and ethambutol, of which the first three are potentially hepatotoxic and exceptionally nephrotoxic. Tuberculosis produces depletion of the zinc concentration which increases the susceptibility to chronicity of the infection. OBJECTIVE: to evaluate the effect of co-administration of zinc and 2RHZE /4HE therapy on hepatic and renal function in patients with pulmonary tuberculosis. METHODS: a, descriptive case-control, randomized double-blind study. 22 patients with pulmonary tuberculosis receiving pharmacological therapy and 22 healthy controls recruited in the health centers Sebastián Pagador and Alalay. The patients were randomly divided into two groups. Who were given zinc (45mg / day) or placebo for three months. All patients were blood sampling before and after intervention to measure hepatic and renal functional tests. For the control subjects were blood sampling before the study to do the same test. RESULTS: no deference was found in the concentration of specific markers of hepatic or renal damage. CONCLUSIONS: the addition of a daily supplement of 45 mg of zinc to 2RHZE/4HE therapy did not cause hepatic, neither renal damage in the people evaluated.

RESUMO

INTRODUCTION AND AIMS: Nonalcoholic fatty liver disease has now become a worldwide health problem, and its dramatic increase is due to the prevalence of diseases such as obesity, type 2 diabetes mellitus, and metabolic syndrome. The aim of our study was to publish the current prevalence of hepatic steatosis in a Mexican population undergoing routine medical check-up, as well as to analyze its relation to BMI, liver function tests, and lipid profile. MATERIALS AND METHODS: An observational, retrospective, cross-sectional study was conducted on patients that underwent medical check-up within the time frame of January 2011 and December 2015 at the Hospital San Javier. Patients included in the study were those with somatometry measurements (BMI), lipid profile, liver function tests, and abdominal ultrasound with a multi-frequency convex transducer. RESULTS: We found that 65% of the patients presented with overweight or obesity and there was a 49.19% prevalence of hepatic steatosis in the study population. That prevalence was more frequent in men and hepatic steatosis was strongly linked to an increase in triglycerides, AST, and GGT and a decrease in HDL. CONCLUSIONS: Establishing the technical aspects of the study was an important aid to having better correlation with and standardization of the accepted definitions, given that ultrasound is an adequate screening technique for an open population. Our results clearly showed a direct relation between hepatic steatosis and alterations in BMI, triglycerides, HDL, ALT, and GGT.

RESUMO

La esteatosis hepática no alcohólica (EHNA) está ampliamente distribuida a nivel mundial y es más frecuente en sujetos con dislipidemia, síndrome metabólico, obesos y con DM2 (34-74%). Sin embargo, la prevalencia de cirrosis por EHNA en la población general no se conoce, lo que es aún materia de investigación en nuestro medio. Objetivo: Determinar si existe diferencia significativa entre los parámetros metábólicos de esteatosis hepática no alcohólica en pacientes con diabetes tipo 2 de reciente diagnóstico controlados y no controlados. Material y métodos: Estudio retrospectivo de tipo caso control, realizado en el Hospital Guillermo Almenara Irigoyen, Lima - Perú, durante los meses de noviembre de 2014 a febrero de 2015. Constó de231 pacientes: 147 pacientes con DM2 de diagnóstico reciente con mal control glicémico y EHNA y 84 pacientes con DM2 de diagnóstico reciente con adecuado control y EHNA. Para el análisis estadístico se utilizó las pruebas de Levene para evaluar homogenidad de varianzas intragrupos y prueba paramétrica de t de student para muestras independientes. Resultados: Luego de aplicar la prueba de homogeneidad de Levene y el t de student para igualdad de medias los parámetros metabólicos significativos fueron el nivel de triglicéridos, el nivel de HbA1C, la dosis de metformina y el género. Conclusiones: Es importante en pacientes diabéticos diagnosticar EHGNA en forma temprana para un control más estricto, no sólo de la glucosa sérica sino de otros parámetros metabólicos, principalmente, los triglicéridos lo cual apoya fuertemente el concepto existente de "múltiples hits " que considera que la EHGNA afecta la homeostasis de la glucosa, y podría ser el punto de partida de nuevas investigaciones que permitan mejorar las intervenciones para reducir la progresión de la cirrosis en pacientes diabéticos y también retrasar la progresión de la diabetes mellitus en pacientes con esteatohepatitis no alcohólica.


Non-alcoholic fatty liver (NASH) is widely distributed around the world and is more common in subjects with dyslipidemia, metabolic syndrome obese and DM2 (34-74%). However, the prevalence of cirrhosis by NASH in general population is unknown which is still subject of research. Objective: To determine if there are significant differences between metabolic parameters of non-alcoholic fatty liver in controlled versus uncontrolled diabetes type 2 of recent diagnosis. Material and methods: retrospective case-control study, performed in the Hospital Guillermo Almenara Irigoyen, Lima, Peru from November 2014 to February 2015.This study included 231 patients: 147 patients (NASH with DM2 of recent diagnosis and poor control) and 84 patients (NASH with DM2 ofrecent diagnosis and adequate control). Statistical analysis: Levene test for evaluating homogeneity of variances intra groups and parametric test for independent samples. Results: After applying Levene test of homogeneity and student test, significant metabolic parameters were the triglycerides, HbA1C level, metformin dose and gender. Conclusions: It is important in diabetic patients to diagnose NASH early for a tighter control, not only of glucose but other metabolic parameters mainly triglycerides which strongly supports existing concept of "multiple hits" which considers NASH affects glucose homeostasis, and it could be the starting point of new research to improve interventions for decreasing progression from to cirrhosis in diabetic patients and also to delay progression of diabetes mellitus in patients with non alcoholic steatohepatitis.

RESUMO

La insuficiencia suprarrenal relativa (ISR) es frecuente en pacientes cirróticos con sepsis grave, asociándose a un pobre pronóstico. Se desconoce su importancia en condiciones de enfermedad estable. El objetivo del trabajo ha sido evaluar la prevalencia de la ISR en una serie de pacientes cirróticos estables y su relación con el deterioro de la función hepática. Se determinó el impacto de la ISR en la supervivencia y se correlacionaron los niveles entre el cortisol basal en plasma y saliva en sujetos controles y cirróticos. Fueron incluidos 47 pacientes ambulatorios y 16 controles. La funcionalidad del eje hipotalámico-pituitario-suprarrenal se valoró mediante la prueba de estimulación con 250 μg de ACTH sintética EV, definiendo la ISR como delta cortisol < 9 μg/dl. Respecto al grado de deterioro de la función hepática, 22 tenían un Child-Pugh ≤ 8 y 25 pacientes = 9. La prevalencia de ISR fue de un 22%, siendo significativamente más elevada en aquellos con mayor deterioro de la función hepática (8/32 vs. 3/13, p < 0.05). Se observó correlación entre el cortisol salival y el plasmático basal (r = 0.6, p < 0.0004). Por último, la supervivencia fue más elevada en los pacientes sin ISR al año (97%) y a los tres años (91%) que aquellos que desarrollaron esta complicación (79 % y 51%, p < 0.05, respectivamente). En resumen, la prevalencia de ISR es elevada en los pacientes con cirrosis estable y se relaciona con un deterioro de la función hepática y una mayor mortalidad.


Relative adrenal insufficiency (RAI) is a common finding in cirrhotic patients with severe sepsis, and increased mortality. Its significance is unknown in stable conditions. The aim of this study was to evaluate the prevalence of RAI in stable cirrhotic patients at different stages of the disease. Also, the impact of RAI on the survival was evaluated and basal cortisol levels between plasma and saliva was correlated in control subjects and cirrhotic patients. Forty seven ambulatory patients and 16 control subjects were studied. RAI was defined as a serum cortisol increase of less than 9 μg/dl from baseline after the stimulation with 250 mg of synthetic ACTH. Twenty two had Child-Pugh ≤ 8 and 25 = 9. The prevalence of RAI in patients with stable cirrhosis was 22%. A higher incidence of RAI was observed in patients with a Child-Pugh = 9 (8/32) than in those with ≤ 8 (3/13, p < 0.05). A correlation between salivary cortisol and basal plasma cortisol (r = 0.6, p < 0.0004) was observed. Finally, survival at 1 year (97%) and 3 years (91%) was significantly higher without RAI than those who developed this complication (79% and 51%, p < 0.05, respectively). In summary, the prevalence of RAI is frequent in patients with stable cirrhosis and that it is related to the severity of liver diseaseand increased mortality.

RESUMO

INTRODUCTION: Vitamin D (VD) is known to have multiple extra-skeletal health functions. There is emerging interest in exploring the relationship between vitamin D and chronic liver disease (CLD). OBJECTIVES: To determine the prevalence of VD deficiency in patients with CLD in our setting and to assess whether VD supplementation influences plasma levels and is associated with improved liver function. MATERIAL AND METHODS: We conducted a study in 2 phases. First, we analysed clinical and epidemiological characteristics in 94 patients with CLD; second, different doses of calcifediol (25-OH-VD) were administered to patients with VD deficiency (<20ng/mL) and insufficiency (20-30ng/mL). Plasma concentrations and liver function (Child-Pugh and MELD) at the end of treatment were compared with baseline data. RESULTS: Deficient or insufficient VD levels were found in 87% of the patients, with an average concentration of 18.8ng/mL. Levels were lower in patients with cirrhosis (15.9ng/mL) (P=.002) and in alcoholic liver disease. VD levels were inversely proportional to the degree of liver function: Child A (16.52ng/mL) vs C (7.75ng/mL). After VD supplementation, optimal serum levels were achieved in 94% of patients and significant improvements were observed in platelet count, albumin levels (P<.05) and functional status assessed by the Child-Pugh scale (P<.05). CONCLUSION: Given the high prevalence of VD deficiency or insufficiency, the need for screening should be considered in the population with CLD. VD supplementation could be safe and effective.

RESUMO

Las pruebas de función hepática se emplean para detectar, diagnosticar específicamente, estimar la severidad, y monitorear el curso de la enfermedad hepática. La interpretación efectiva del panel de función hepática requiere un conocimiento de la fisiopatología subyacente y las características de las pruebas del panel. Utilizando un enfoque esquemático, se clasifican las alteraciones hepáticas en dos grandes categorías: 1) necrosis celular y 2) colestasis, y aplicando el panel de función hepática recomendado por The National Academy of Clinical Biochemistry y la American Association for the Study of Liver Diseases, se interpretan las principales pruebas y su utilidad para evaluar inicialmente las enfermedades hepáticas sospechadas o conocidas de acuerdo con su capacidad para detectar daño celular, falta de permeabilidad de vías biliares, metabolismo aniónico orgánico y síntesis proteica. Finalmente se hacen unas recomendaciones para la interpretación del panel de pruebas dentro del contexto clínico.

RESUMO

Debido a la ausencia de publicaciones de trabajos de investigación venezolanos sobre valores de referencia de los parámetros bioquímicos que evalúan la función hepática en población infantil sana, los profesionales del área de la salud se basan en su propia experiencia y en la de sus colegas, para interpretar los resultados de estas pruebas o simplemente utilizan los valores establecidos para las casas comerciales o los de la literatura internacional; los cuales no son adecuados, porque pertenecen a poblaciones de otros países en donde existen condiciones ambientales, dieta, estilo de vida, entre otros factores, diferentes a los de nuestra región, y en su mayoría corresponden a adultos. Por lo que se propuso establecer los valores de referencia de los niveles séricos de la albúmina, bilirrubina total, bilirrubina directa, bilirrubina indirecta y de la actividad enzimática de la alanino aminotransferasa, aspartato aminotransferasa, gamma glutamiltransferasa y fosfatasa alcalina en la población infantil sana del municipio Sucre, estado Sucre y compararlos con los valores de referencia establecidos para la casa comercial de los reactivos utilizados (Olympus Diagnostica), cuantificando cada uno de estos parámetros, en sueros de 486 niños, con edades entre los 3–11 años, clasificados según la edad y sexo para determinar el efecto y la interacción de éstos dos factores a través de un análisis de varianza de dos vías y una prueba a posteriori, el cálculo de los intervalos de referencia se realizó mediante los percentiles 2,5 y 97,5. Encontrando que para establecer los valores de referencia para los niveles séricos de albúmina, bilirrubina total, directa e indirecta se consideró solo la variable edad; mientras que para los valores de referencia de la aspartato aminotransferasa y la fosfatasa alcalina fueron consideradas las dos variables (edad y sexo), y en el caso de la alanino aminotransferasa y gamma glutamiltransferasa no se consideraron...


Due to absence of publications in Venezuela of investigation paperwork on reference values of biochemical parameters that evaluate the hepatic function in infantile healthy population, the health professionals base on their own experience and on his colleagues, to interpret the results of these tests, simply there use the values established by the business firms or those found on the international literature, which are not adapted, because they belong to populations of other countries where there exist environmental conditions, diet, way of life, among other factors, different from those of our region, and mainly they correspond to adults. Because of this, it was proposed to establish the reference values of the serum levels of the albumin, total bilirubin, direct bilirubin, indirect bilirubin and of the enzymatic activity alanine aminotransferase, aspartate aminotransferase, gamma glutamyltransferase and alkaline phosphatase in the infantile healthy population of the Sucre municipality at Sucre State and compare them with the established reference values of the business firm of the used reagents (Olympus Diagnostic), quantifying each of these parameters, in 486 children’s serum, with ages between 3-11 years classified according to the age and sex to determine the effect and the interaction of these two factors through a analysis of variance of two lines and a posteriori tests, the calculation of the intervals of reference fulfilled by means of the percentiles 2,5 and 97,5. Finding that, to establish the values of reference of the serum levels of albumin, total, direct and indirect bilirubin was considered only the age variable; whereas for the reference values of the aspartate aminotransferase were considered both variables (age and sex), and in the case of alanino aminotransferasa and gamma glutamiltransferasa age and sex were not considered. Concluding that the established reference values differ from the recommended...
