RESUMO

Abstract Introduction: Esophageal varices represent one of the main complications in patients with liver cirrhosis. The main objective was to determine the diagnostic performance of the new Baveno VII criteria to exclude the presence of esophageal varices in compensated advanced chronic liver disease (cACLD), in an independent Peruvian population. Materials and methods: A cross-sectional study, including patients with cACLD, upper digestive endoscopy, and transient hepatic elastography from January 2017 to December 2019. Results: The mean age was 59.4 (12.9) years, while the mean measurement of liver stiffness was 27.21 (14.6) kPa. The prevalence of esophageal varices was 85.6%; non-alcoholic fatty liver disease (NAFLD) (63.6%) was the most prevalent etiology, followed by viral hepatitis (14.4%). For esophageal varices exclusion, Baveno VII criteria for all etiologies demonstrated adequate sensitivity and negative predictive value (sensitivity: 96.7%; 95% confidence interval [CI]: 92.3%-98.8%; negative predictive value: 76.9%, 95% CI: 56.4% -91%). However, better diagnostic performance was found when applying the Baveno VII criteria without considering NAFLD patients (sensitivity: 98.4%, 95% CI: 79.2% -99.2%; negative predictive value: 90.9%, 95% CI: 79.2% -99.2%). This would prevent 14% of endoscopic studies with a 9% risk of failing to detect esophageal varices. Conclusions: The Baveno VII criteria present good diagnostic performance for the exclusion of esophageal varices, especially in patients with cACLD without NAFLD, in an independent Peruvian population.


Resumen Introducción: Las várices esofágicas representan una de las principales complicaciones en pacientes con cirrosis hepática. El objetivo principal fue determinar el rendimiento diagnóstico de los nuevos criterios de Baveno VII para excluir la presencia de várices esofágicas en la enfermedad hepática crónica compensada (cACLD), en una población peruana independiente. Materiales y métodos: Estudio transversal que incluyó a pacientes con cACLD, endoscopia digestiva alta y elastografía hepática transitoria desde enero de 2017 hasta diciembre de 2019. Resultados: La edad media fue de 59,4 (12,9) años, mientras que la medición media de rigidez hepática fue de 27,21 (14,6) kPa. La prevalencia de várices esofágicas fue del 85,6%; la enfermedad metabólica asociada al hígado graso (MASLD) (63,6%) fue la etiología más prevalente, seguida de la hepatitis viral (14,4%). Para la exclusión de várices esofágicas, los criterios de Baveno VII para todas las etiologías demostraron una sensibilidad y un valor predictivo negativo adecuados (sensibilidad: 96,7%; intervalo de confianza [IC] del 95%: 92,3%-98,8%; valor predictivo negativo: 76,9%, IC 95%: 56,4%-91%). Sin embargo, se encontró un mejor rendimiento diagnóstico al aplicar los criterios de Baveno VII sin considerar a los pacientes con MASLD (sensibilidad: 98,4%, IC 95%: 79,2%-99,2%; valor predictivo negativo: 90,9%, IC 95%: 79,2%-99,2%). Se evitaría el 14% de estudios endoscópicos con un riesgo del 9% de no detectar várices esofágicas. Conclusiones: Los criterios de Baveno VII presentan buen rendimiento diagnóstico para la exclusión de várices esofágicas, especialmente en pacientes con cACLD sin MASLD, en una población peruana independiente.

RESUMO

INTRODUCTION: COVID-19 affects the liver, causing alteration in liver biochemistry tests such as aspartate transferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), total bilirubin and albumin. OBJECTIVE: To determine the prevalence of alteration in liver functions tests and associated factors for severity among Peruvian COVID-19 patients. MATERIALS AND METHODS: A descriptive, retrospective and cross-sectional study was performed in 4 public hospitals in Peru. Patients admitted to hospitalization wards and intensive care units with a diagnosis COVID-19 were enrolled. The evaluation of AST, ALT, ALP, totalbilirubin and albumin was performed. Associations with demographic and medical data were assessed. RESULTS: 1,100 patients were enrolled, of which 81.7% had altered liver function tests. Only 2.8% of the patients had cirrhosis and 2.1% hepatitis B/C virus. AST and ALT were altered at admission in 64.7% and 63.7%, of the patients respectively. Factors associated with liver injury were: being female OR=0.53 (95% CI: 0.39-0.73; p<0.01), dyslipidemia OR=1.72 (95% CI: 1.10-2.70; p=0.01), previous medication OR=1.56 (95% CI: 1.12 -2.16, p<0.01) and fever OR=1.43 (95% CI: 1.03-1.199, p=0.03). Disease severity was associated with levels of AST and ALT (p<0.01). Patients taking self-medication OR=1.56 (95% CI: 1.12-2.16; p<0.01) and paracetamol OR= 1.41 (95% CI:1.01-1.98; p=0.04) had higher risk of liver injury. Meanwhile, corticosteroids OR=0.55 (95% CI: 0.38-0.78; p<0.01) and enoxaparin OR=0.53 (95% CI: 0.35- 0.81; p<0.01) were protective factors. CONCLUSIONS: Peruvian patients with COVID-19 presented high prevalence of alteration in liver function tests, high levels of AST and ALT were related to disease severity.

Introducción: La COVID-19 afecta al hígado, provocando alteración en las pruebas de función hepática como aspartato aminotransferasa (AST), alanina aminotransferasa (ALT), fosfatasa alcalina (FA), bilirrubina total y albúmina. Objetivo: Determinar la prevalencia de alteración en las pruebas de función hepática y su asociación con la severidad en pacientes peruanos con COVID-19. Materiales y métodos: Se realizó un estudio descriptivo, retrospectivo y transversal en 4 hospitales públicos del Perú. Se incluyeron pacientes admitidos en hospitalización y unidades de cuidados intensivos con diagnóstico de COVID-19. Se realizó la evaluación de AST, ALT, FA, bilirrubina total y albúmina. Se evaluaron las asociaciones con datos demográficos y médicos. Resultados: Se incluyeron 1,100 pacientes, de los cuales el 81,7% presentaba alteraciones en las pruebas de función hepática. Solo el 2,8% de los pacientes tenía cirrosis y el 2,1% infección por virus de la hepatitis B / C. Se encontraron niveles alterados de AST y ALT al ingreso en el 64,7% y 63,7% de los pacientes, respectivamente. Los factores asociados con alteración en pruebas de función hepáticas fueron: ser mujer OR = 0,53 (IC 95%: 0,39-0,73; p <0,01), dislipidemia OR=1,72 (IC 95%: 1,10-2,70; p=0,01), uso de medicación previa OR = 1,56 (IC del 95%: 1,12 -2,16, p <0,01) y fiebre OR = 1,43 (IC del 95%: 1,03-1,199, p = 0,03). La gravedad de la enfermedad se asoció con los niveles de AST y ALT (p <0,01). Los pacientes que se automedicaban OR = 1,56 (IC 95%: 1,12-2,16; p <0,01) y tomaban paracetamol OR = 1,41 (IC 95%: 1,01-1,98; p =0,04) tenían mayor riesgo de injuria hepática. Mientras tanto, los corticosteroides OR=0,55 (IC del 95%: 0,38-0,78; p <0,01) y la enoxaparina OR=0,53 (IC del 95%: 0,35-0,81; p <0,01) fueron factores protectores. Conclusiones: los pacientes peruanos con COVID-19 presentaron alta prevalencia de alteración en las pruebas de función hepática, niveles elevados de AST y ALT se relacionaron con la gravedad de la enfermedad.

RESUMO

Resumen En el cuerpo humano tenemos glucosamina y condroitina de forma natural. Estas sustancias constituyen un componente importante del sistema cartilaginoso. Como medicamentos, tienen múltiples indicaciones clínicas, principalmente la osteoartritis. La hepatotoxicidad inducida por estas biomoléculas es infrecuente, pues cuentan solo con reportes de casos aislados en la literatura mundial. En este trabajo, presentamos el caso de una paciente con una lesión hepática inducida por glucosamina-condroitina del tipo hepatocelular, que fue admitida en el hospital por causa de una sintomatología respiratoria y malestar general. En ella, se destacó una marcada hipertransaminasemia durante los exámenes de laboratorio. Asimismo, se descartaron etiologías como el alcohol, hepatitis virales y hepatopatías autoinmunes, principalmente. De igual forma, no se llegó a evidenciar una enfermedad hepática crónica mediante la ecografía abdominal. Al suspenderse el medicamento, se observó una disminución considerable de la hipertransaminasemia luego de 1 semana, y una mejoría total de esta a los 2 meses del alta hospitalaria. Este caso se añade a los pocos reportados a nivel mundial y cobra una importancia relevante para la publicación de posteriores estudios sistemáticos que aclaren el panorama de esta enfermedad.


Abstract The human body naturally produces glucosamine and chondroitin which are important components of the cartilaginous system. There are multiple clinical indications for them as medicines, but they are primarily used for osteoarthritis. Hepatotoxicity induced by these biomolecules is uncommon, and the only reports in the world literature are isolated individual cases. This article presents the case of a patient with glucosamine-chondroitin-induced hepatocellular damage who was admitted to the hospital with respiratory symptoms and malaise. Marked hypertransaminemia was found in laboratory tests. Etiologies such as alcohol, viral hepatitis and autoimmune liver diseases were ruled out, and abdominal ultrasound found no evidence of chronic liver disease. Discontinuance of glucosamine and chondroitin led to a considerable decrease in hypertransaminemia after one week with total improvement two months of hospital discharge. This case adds to the small number reported worldwide and is relevant for future systematic studies to clarify the outlook for this disease.

RESUMO

Introducción: Determinar la asociación entre insuficiencia hepática crónica agudizada (ACLF) y la mortalidad en pacientes cirróticos en el Hospital Nacional Arzobispo Loayza, Lima - Perú. Material y métodos: Estudio observacional, analítico y de cohorte. Se realizó un seguimiento durante 28 días a todos los pacientes inicialmente diagnosticados con cirrosis hepática descompensada que ingresaron al hospital entre los meses de diciembre 2015 y junio 2016. Para la tipificación de los participantes como ACLF se utilizó la escala del CLIF-ACLF. Para evaluar la normalidad de los datos cuantitativos se usó el estadístico de Shapiro Wilk. En el análisis se utilizó las curvas de supervivencia y la regresión de Poisson. Resultados: Fueron 46 pacientes los que ingresaron con el diagnóstico de interés en el lapso de los meses ya referidos; de ellos, sólo 34 aceptaron formar parte del estudio. La media de la edad fue 63,12 ± 11,97. El 52,94% (n=18) fueron mujeres. El porcentaje de pacientes cirróticos con ACLF fue de 26.47% (n=9). La etiología más frecuente de cirrosis hepática fue la esteatosis hepática no alcohólica en un 44,12% (n=15), mientras que en un 29.62% (n=9) la infección bacteriana fue el motivo mayor reportado que originó su descompensación e ingreso hospitalario. Se evidenció asociación entre el haber padecido de ACLF con la mortalidad en pacientes cirróticos (RRa=5,81 IC95 % [2,22; 15,18]; p<0,001) y un HRa=5,63 (IC95 % [1,25; 25,27]; p=0,024). Conclusiones: Los pacientes con cirrosis hepática tienen mayor probabilidad de morir si son tipificados como ACLF (AU)

RESUMO

Hypertriglyceridemia-induced acute pancreatitis occurs in about 1-4% of the cases. It is the third leading cause of pancreatitis after biliary and alcoholic etiology. Hypertriglyceridemia can be caused by primary causes, lipid metabolism disorders and secondary causes. A 32 year old man, born in Huancayo, with a history of diabetes mellitus type 2, severe mixed dyslipidemia with primary hypertriglyceridemia, was admitted to emergency with 10 days of abdominal pain with moderate intensity in epigastrium and left hypochondrium spreading to dorsal region after intake of high-fat meal. 24 hours before admission, pain exacerbates increasing intensity and causing nausea and bilious vomits. Therefore, all laboratory examinations are carried out resulting in hypertriglyceridemia-induced acute pancreatitis. For that reason, an adequate clinical history physical examination associated with laboratory and image examinations are important to consider hypertriglyceridemia as part of the etiology of acute pancreatitis.

RESUMO

La pancreatitis aguda por hipertrigliceridemia se presenta en aproximadamente 1-4 % de los casos, es la tercera causa de pancreatitis luego de la etiología biliar y alcohólica. La hipertrigliceridemia puede ser producida por causas primarias asociadas a trastornos genéticos en el metabolismo de los lípidos, y por casusas secundarias. Se presenta el caso de un paciente varón de 32 años de edad, natural de Huancayo, con antecedentes de diabetes mellitus tipo 2, dislipidemia mixta severa con hipertrigliceridemia primaria que ingresa de emergencia con un cuadro de 10 días de evolución caracterizado por dolor abdominal de moderada intensidad en epigastrio e hipocondrio izquierdo y que se irradia hacia región dorsal post ingesta de comida copiosa grasa, 24 horas antes del ingreso el dolor se reagudiza aumentando en intensidad, asociándose náuseas y vómitos de contenido bilioso. Por lo cual se le toman los exámenes de laboratorio correspondientes los cuales son compatibles con pancreatitis aguda por hipertrigliceridemia severa. Por tal motivo la realización de una adecuada historia clínica, un buen examen físico asociado a pruebas laboratoriales y de imagen son importantes para tener en cuenta a la hipertrigliceridemia como parte de la etiología de la pancreatitis aguda...

RESUMO

El Linfoma no Hodgkin (LNH) extraganglionar es una neoplasia maligna que corresponde al 40% de los casos de LNH, siendo el tracto gastrointestintal (TGI) la localización más común. Dentro del TGI es el estómago el órgano más afectado (60%). Presentamos el caso de un hombre de 52 años trabajador en empresa minera por más de 10 años, el cual es derivado al Servicio de Gastroenterología por presentar un cuadro de epigastralgia, náuseas y baja de peso. La endoscopía digestiva mostró una lesión ulcerada en cuerpo gástrico a la cual se le tomaron múltiples biopsias. El estudio histológico y el posterior análisis inmunohistoquímico permitieron realizar el diagnóstico de LNH B difuso de células grandes. Asimismo, el paciente presentó compromiso de múltiples órganos en relación a exposición crónica de metales pesados, lo cual fue comprobado en el mineralograma, siendo las de mayor concentración el uranio, talio, arsénico, plomo y mercurio. En la literatura se ha descrito la asociación de exposición laboral crónica a Uranio y Arsénico con la presentación de LNH de compromiso gastrointestinal. Por tal motivo, el compromiso gástrico no se puede considerar como un daño aislado, sino más bien parte del compromiso sistémico asociado a concentraciones elevadas de metales. La minería constituye el principal motor de ingresos económicos para el Perú, sin embargo, no existen reportes hasta la fecha de la asociación de LNH de compromiso gastrointestinal en relación a exposición laboral a metales pesados.


Primary extranodal Non-Hodgkin lymphoma (NHL) is a non epithelial tumours that accounts for 40% of cases of NHL. Spread of nodal lymphomas to the gastrointestinal tract (GIT) is the most common location. Within the GIT is the stomach the most affected organ (60%). We report the case of 52-year- old man, mining company worker for over 10 years, which is derived to the Service of Gastroenterology with history of epigastric pain, nausea, vomiting and weight loss. Upper gastrointestinal endoscopic examination revealed an ulcerated lesion on greater curve of stomach and histopathological examination and subsequent immunohistochemical analysis showed diffuse large B cell gastric NHL. Also, the patient had multiple organ involvement in relation to chronic exposure to heavy metals, which was found in the mineralograma, with the highest concentration of uranium, thallium, arsenic, lead and mercury. The literature has described the association of chronic occupational exposure to uranium and arsenic with NHL presenting gastrointestinal involvement. Therefore, gastric commitment can not be considered as an isolated injury, but rather part of systemic involvement associated with elevated concentrations of metals. Mining is a key driver of income for Peru; however, there are no reports to date of the association of gastrointestinal NHL commitment regarding occupational exposure to heavy metals.

RESUMO

La hemoglobinopatía S, depranocitosis o enfermedad de células falciformes constituye la hemoglobinopatía más frecuente en el mundo. En su forma heterocigota (Sickle Cell Trait) afecta el 8 por ciento de la población negra de los EUA y al 25 por ciento de la población negra africana, y en menor frecuencia en la zona del mediterráneo, India, Medio Oriente y América Latina. La alteración básica es la sustitución del ácido glutámico de la posición 6 de la cadena beta de Globina por Valina, la cual polimeriza a baja tensión de oxigeno; distorsionando la estructura del hematíe, aumentando la viscosidad sanguínea, bloqueando la circulación arterial capilar de diferentes áreas del organismo produciendo así microinfartos. Aunque el Infarto esplénico es raro, es reconocido como una dramática complicación de la enfermedad heterocigota de células falciformes (Sickle Cell Trait). Presentamos el caso de un paciente varón de 21 años de edad, mestizo, que cursa con un cuadro agudo de dolor abdominal posterior al arribo a la ciudad minera de Casapalca (ubicado en la Sierra del Perú; a 4200 msnm) por causas laborales y es derivado a nuestro Hospital en Lima para estudio. Presentamos el caso por ser una inusual causa de dolor abdominal agudo y por ser esta entidad poco frecuente en nuestro medio y con escasas publicaciones al respecto.


Hemoglobinopathy S, Depranocytosis or Sickle Cell Disease is the most commonhemoglobinopathy in the world. In its heterozygous form (Sickle Cell Trait), it affects 8 per cent of the black population in the U.S. and 25 per cent of the black population in Africa, and is found less frequently in the Mediterranean area, India, Middle East and Latin America. The basic alteration is a substitution of glutamic acid by valin in the sixth position of the beta globin chain, which causes polymerization at low oxygen tension thereby distorting the structure of erythrocytes and increasing blood viscosity, which,in turn, generates obstructions of the capillary arterial blood flow to different areas of the body thus causing microinfarctions. Although Splenic Infarction is rare, it is recognized as a serious complication of Heterozygous Sickle Cell Disease (Sickle Cell Trait).We present the case of a 21 year-old mestizo male patient who came in with an acute case of abdominal pain after arriving to work in the Casapalca mining city (located in the Peruvian Andes at 4200 m.a.s.l.) and was referred to our Hospital in Lima for exams. We present the case because it is an unusual cause of acute abdominal pain, and because this condition is rare in Peru and there are few publications about it.
