ABSTRACT

Definida como una concentración sérica de bilirrubina, la hiperbilirrubinemia es una condición rara y puede ser causada por cualquier factor que eleve la carga de bilirrubina a ser metabolizada por el hígado. Así, la bilirrubina se distribuye por los tejidos corporales y se acumula en los tejidos duros, incluso, en los dientes primarios. El objetivo de este trabajo es relatar un caso clínico sobre la repercusión severa de la hiperbilirrubinemia en dientes primarios y sus manifestaciones bucales en la primera infancia, como dientes verdosos. Paciente del sexo masculino, 3 años y 8 meses, estuvo en clínica odontológica para evaluación de "manchas verdes en los dientes". En su historia médica se observó que nació prematuro y tuvo complicaciones posparto que evolucionaron para sepsis Dientes primarios verdes por hiperbilirrubinemiaIvana Aguiar Raposo,1.....

El examen clínico dental constató la presencia de manchas verdes en los 20 dientes primarios, ausencia de lesión de caries, encías sanas y buena condición de higiene bucal. Se concluye que los altos niveles de bilirrubina desarrollados por el niño prematuro asociados a septicemia pueden llevar a la pigmentación verde (coloración intrínseca) en los dientes primarios durante el periodo de calcificación de los mismos (odontogénesis), incluso a la afectación de los dientes permanentes. Por eso, es relevante el conocimiento de la historia médica del niño desde el nacimiento para el establecimiento del diagnóstico y pronóstico de las alteraciones dentales


Defined as a serum bilirubin concentration, hyperbilirubinemia is a rare condition and can be caused by any factor that raises the bilirubin load to be metabolized by the liver. Thus, bilirubin is distributed throughout the body's tissues and accumulates in hard tissues, including primary teeth. The aim of this work is to report a clinical case about the severe repercussion of hyperbilirubinemia in primary teeth, and its early childhood manifestations, such as greenish teeth. A male patient, 3 years and 8 months old, attended the dental clinic for evaluation of "green spots on teeth". Medical history revealed that the child had premature birth and postpartum complications that evolved into sepsis, and due to the use of several drugs, developed hyperbilirubinemia. The dental clinical examination showed the presence of green spots on all 20 deciduous teeth, absence of carious lesions, healthy gums and good oral hygiene conditions. We conclude

ABSTRACT

Introducción: Se estableció como objetivo determinar la utilidad clínica del marcador tumoral CA 19-9 en ictericia obstructiva de origen benigno y maligno en pacientes adultos que acuden al servicio de gastroenterología del Hospital Universitario de Caracas. Pacientes y métodos: se estableció como muestra a todos los pacientes que fueron hospitalizados en el Servicio de Gastroenterología del Hospital Universitario de Caracas con ictericia obstructiva, a los cuales se les realizó la determinación del CA 19-9 antes y siete días después del drenaje de la vía biliar a través de una colangiopancreatografía retrógrada endoscópica y se determinó la variación de los valores de CA 19-9 y si este valor permitió diferenciar entre ambas etiologías. Resultados: Los valores de CA 19-9 no se modificaron de forma significativa después del drenaje biliar en la patología benigna ni en la maligna. Se obtuvo un nuevo punto de corte para el CA 19-9 (47U/L), manteniendo la sensibilidad, pero aumentando la especificidad. Conclusiones:No se puede utilizar la variación del CA 19-9 después del drenaje biliar como elemento diagnóstico para diferenciar entre enfermedad benigna o maligna biliopancreática.

ABSTRACT

Background Alcoholic liver disease is a major cause of end-stage liver disease worldwide and severe forms of alcoholic hepatitis are associated with a high short-term mortality. Objectives To analyze the importance of age-bilirubin-INR-creatinine (ABIC) score as an index of mortality and predictor for complications in patients with alcoholic hepatitis. To evaluate its correlation with those complications, with risk of death, as well as the scores model for end stage liver disease (MELD) and Maddrey’s discriminat function. Methods A total of 46 medical records of patients who had been hospitalized with alcoholic hepatitis were assessed retrospectively with lab tests on admission and after seven days. Score calculations were carried out and analyzed as well. Results The scores showed positive reciprocal correlation and were associated with both hepatic encephalopathy and ascites. ABIC index, which was classified as high risk, presented as a risk factor for these complications and for death. In univariate logistic regression analysis of mortality, the ABIC index at hospital admission odds ratio was 19.27, whereas after 7 days, it was 41.29. The average survival of patients with ABIC of low and intermediate risk was 61.1 days, and for those with high risk, 26.2 days. Conclusions ABIC index is a predictor factor for complications such as ascites and hepatic encephalopathy, as well as for risk of death. Thus, it is a useful tool for clinical practice. .


Contexto A doença hepática alcoólica é uma das maiores causas de doença hepática avançada no mundo, sendo que as formas graves de hepatite alcoólica estão associadas a alta mortalidade a curto prazo. Objetivos Avaliar a importância do índice age-bilirrubin-INR-creatinine (ABIC) como fator prognóstico na hepatite alcoólica e sua correlação com as complicações dessa doença, com o risco de óbito e com os escores Model for End stage Liver Disease (MELD) e Função Discriminante de Maddrey. Métodos Um total de 46 prontuários de pacientes internados por hepatite alcoólica foram avaliados de forma retrospectiva. Foi realizado levantamento de exames laboratoriais do primeiro dia de internação e 7 dias após, além de cálculo dos escores estudados. Resultados Os índices ABIC, Maddrey e MELD apresentaram correlação positiva entre si e associaram-se a encefalopatia hepática e a ascite (P<0,05). O índice ABIC, classificado de alto risco, foi fator de risco para essas complicações e para óbito. Em análise de regressão logística univariada para óbito, a razão de risco do ABIC de entrada no hospital foi de 19,27 (P=0,012) e após 7 dias de 41,29 (P=0,002). A sobrevida acumulada daqueles com ABIC de alto risco foi de 93,3% em 7 dias e de apenas 26,9% em 60 dias. Conclusões O índice prognóstico ABIC é fator de predição para complicações como ascite e encefalopatia hepática, assim como para risco de óbito, sendo ferramenta útil na prática clínica. .

ABSTRACT

Se evaluó la relación entre biomarcadores de estrés oxidativo (ácido úrico, bilirrubina y proteína C-reactiva) con el estado nutricional en 321 adultos de Ecuador, pertenecientes al personal administrativo de la Universidad Técnica del Norte, con edades de 43 ± 10 años, (46,30% femenino y 53,61% masculino). Se obtuvo información sociodemográfica, de estilo de vida y epidemiológica; se calculó el índice de Masa Corporal (IMC), porcentaje de grasa y agua corporal, se midió la circunferencia de la cintura (CC) y la presión arterial y se determinó las concentraciones de ácido úrico, bilirrubina y Proteína C reactiva (PCR). Se encontró que 17,9% de la población presentó obesidad y 51,72% sobrepeso. Los valores más elevados de ácido úrico se encontraron en obesos, hipertensos y en quienes realizan actividad física. La bilirrubina total, directa e indirecta se encontró en límites superiores en los grupos con obesidad abdominal, y con actividad física. Las variables % de grasa y de agua influyen en la PCR en el grupo con baja grasa corporal y en las mujeres. En hombres, la PCR se asocia con IMC y CC. En los grupos sobrepeso, alta grasa corporal y PHT, el ácido úrico mostró relación con el % de grasa y la CC En los obesos con el % de agua e IMC y en los grupos obesidad abdominal e HT se asoció con % de agua y CC Se concluye que el porcentaje de agua corporal es un importante indicador nutricional para el desarrollo de estrés oxidativo en esta población.


In this work it was evaluated the relationship between oxidative stress biomarkers (uric acid, bilirubin and C-reactive protein) with nutritional status in 321 adults of Ecuador, belonging to administrative staff of of the Universidad Tècnica del Norte , aged 43 ± 10 years old (46 30% female and 53.61% male). Socio demographic and epidemiological information and lifestyle were obtained through a survey; The Body Mass Index (BMI) and body fat and body water percentages were calculated; waist circumference (WC) and blood pressure was measured. Determinations of uric acid, bilirubin, and serum C-reactive protein (PCR) were performed. 17.9% of the populations were obese and 51.72% overweight. The highest values of uric acid were found in obese, hypertensive and physical activity groups. The total direct and indirect bilirubin were found in upper limits in abdominal obesity and physical activity groups. The CRP level was influenced by % fat and % water in the low body fat group and in females. In male, BMI and WC were associated with CRP. Uric acid showed relationship with % fat and WC in overweight, high body fat and PHT groups, uric acid was associated with the % water and BMI in obese. Finally, uric acid was associated with % water and the WC in the abdominal obesity, and HT groups’ .The body water percentage is an important indicator to development of oxidative stress in this population.

ABSTRACT

El objetivo de la presente investigación fue correlacionar los valores séricos de bilirrubina con el índice de Kramer en un grupo de pacientes con ictericia neonatal de tres diferentes etnias. Representa un estudio prospectivo, aleatorio, observacional descriptivo-analìtico, longitudinal, comparativo y controlado en 50 recién nacidos con ictericia neonatal sin complicaciones. Se dividieron en 3 grupos: A (Control), n = 25 de origen caucásico; B, n = 15 de origen indígena local Wayúu y C, n = 10 de origen Afro americano. Al ingreso, a cada neonato se le determinaron las zonas dérmicas de Kramer y se le tomó una muestra de sangre venosa braquial para medir la bilirrubina de ingreso. Los valores al ingreso fueron: bilirrubina sérica 12,02 ± 3,41 mg/dL y el 62,8% estaban en nivel 3 de Kramer. No hubo diferencias entre los grupos étnicos estudiados y la correlación bilirrubina sérica-índice de Kramer fue de r= 0,93 (p < 0,005). Al 3er día se empezó a notar el descenso de la bilirrubina y de los índices de Kramer. El método de Kramer ofrece múltiples ventajas en la evolución del RN ictérico. No se encontraron diferencias raciales. Se recomienda implementar la aplicación de este método de Kramer en todas las unidades de neonatos en los hospitales, preferentemente en aquellas que carezcan de bilirrubinómetros transcutáneos.


The objective of the present study was to correlate seric values of bilirubin with the Kramer’s index in a group of newborns with neonatal jaundice, from three different ethnic groups. This was a prospective, randomized, observational, descriptive-analytical, longitudinal, comparative and controlled study of 50 newborns with neonatal jaundice, without complications. They were divided into three groups: A (Control), n = 25, of Caucasian descent; B, n = 15, of local indigenous descent (Wayúu) and C, n = 10, of Afro-American descent. Each newborn was screened at the start of the study for their Kramer’s dermic areas and simultaneously, a venous blood sample from the arm was taken for bilirubin quantification. They were compared through a correlation-regression analysis. Values at the beginning of the study were: serum bilirubin 12.02 ± 3.41 mg/dL, and 62.8% of neonates were at Kramer’s level 3. There were no differences among the ethnic groups studied and the correlation bilirubin/Kramer’s index was r= 0.93 (p < 0.005). At the third day, both bilirubin and Kramer’s indexes started to decrease. There were no ethnic differences. In conclusion, the Kramer’s method offers multiple advantages to evaluate a jaundiced newborn; it is a safe, non-invasive method with no cost. Besides, it is of great help in the prevention of the kernicterus. It is recommended to implement the use of the Kramer method in all the newborns units in our Hospitals, preferably in those lacking transcutaneous bilirubinometers.

ABSTRACT

La bilirrubina no es simplemente el producto final del metabolismo del hem. En la actualidad, se considera que es una sustancia fundamental como antioxidante y antiinflamatoria del suero. Por su capacidad de neutralizar radicales libres evita la peroxidación de los lípidos y hay evidencia de que posee efectos protectores cardiovasculares, neuronales, hepatobiliares, pulmonares e inmunológicos. Recientemente se ha considerado que la utilización de agentes farmacológicos que aumenten la expresión de la hem oxidasa 1 (HO-1) y por ende de sus metabolitos como el monóxido de carbono (CO), la biliverdina (BV) y de la bilirrubina (BR) puede ser una estrategia terapéutica para diferentes enfermedades inflamatorias.


Bilirubin is more than just the final product of heme catabolism. Today it is considered to be a fundamental substance which acts as an antioxidant and anti-inflammatory agent in the serum. It can neutralize free radicals and prevent peroxidation of lipids. In addition there is evidence that it protects the cardiovascular system, neuronal systems, the hepatobiliary system, the pulmonary system and the immune system. Recently the use of pharmacological agents which augment expression of Heme oxygenase 1 (HO-1) has been considered. Consequently its metabolites such as carbon monoxide (CO), biliverdin (BV) and Bilirubin (BR) could become parts of a therapeutic strategy for treatment of various inflammatory illnesses.
