Normal transaminases in obese patients with metabolic associated steatohepatitis (MASH): a cohort of Peruvian patients.

INTRODUCTION: Metabolic associated steatohepatitis (MASH) is one of the most frequent causes of chronic liver disease. Liver transaminases are important biomarkers to measure liver injury, however, a proportion of patients with MASH may present with normal levels of transaminases. The levels of serum transaminases may not correlate with the severity of histopathological changes. OBJECTIVE: We aimed to identify the frequency of normal transaminases in obese patients with MASH, as well as to describe the clinical, biochemical and histological characteristics in this specific group of patients. MATERIALS AND METHODS: A retrospective cross-sectional study was conducted in the bariatric surgery service of a private clinic. Obese patients older than 18 years with a body mass index (BMI) >30Kg/m2 and 2 co-morbidities undergoing a gastric sleeve surgery were included. Measurement of biochemical routine laboratory exams was performed. Insulin resistance was calculated using the homeostasis evaluation model (HOMA-IR). All patients underwent liver biopsies prior to surgery and the diagnosis of MASH was based on the Brunt criteria. RESULTS: 159 obese patients with MASH were included, of which 47.2% had normal transaminases and 52.8% elevated transaminases. Factors associated with alteration in transaminases were: being male OR=4.02 (95% CI: 2.03- 7.96; p<0.01), diagnosis of type 2 diabetes mellitus OR=4.86 (95% CI: 1.97- 11.95; p<0.01) and levels of GGT >50 IU/L OR=7.50 (95% CI: 3.40-16.56; p<0.01). The values of HOMA-IR and GGT were significantly higher in the group of high transaminases (p<0.01). Differences in the degree of fibrosis were not associated with transaminases levels. CONCLUSION: In conclusion we found that the frequency of normal transaminases was 47.2% in obese patients with MASH. Factors associated with elevation in liver enzymes were being male, diagnosis of diabetes mellitus and elevation in GGT levels. The degree of fibrosis was not associated with elevations in liver transaminases. These findings suggest that transaminases levels alone are not accurate markers to assess liver injury, as they do not necessarily correlate with histological liver damage.

Introducción: La esteatohepatitis asociada metabólica (MASH) es una de las causas más frecuentes de enfermedad hepática crónica. Las transaminasas hepáticas son biomarcadores importantes para medir el daño hepático; sin embargo, una proporción de pacientes con MASH pueden presentar niveles normales de transaminasas. Los niveles de transaminasas séricas pueden no estar correlacionados con la gravedad de los cambios histopatológicos. Objetivo: Nuestro objetivo fue identificar la frecuencia de transaminasas normales en pacientes obesos con MASH, así como describir las características clínicas, bioquímicas e histológicas en este grupo específico de pacientes. Materiales y métodos: Se realizó un estudio transversal retrospectivo en el servicio de cirugía bariátrica de una clínica privada. Se incluyeron pacientes obesos mayores de 18 años con índice de masa corporal (IMC) >30Kg/m2 y 2 comorbilidades sometidos a cirugía de manga gástrica. Se realizó la medición de los exámenes bioquímicos de laboratorio de rutina. La resistencia a la insulina se calculó mediante el modelo de evaluación de la homeostasis (HOMA-IR). Todos los pacientes se sometieron a biopsias hepáticas antes de la cirugía y el diagnóstico de MASH se basó en los criterios de Brunt. Resultados: Se incluyeron 159 pacientes obesos con MASH, de los cuales el 47,2% tenían transaminasas normales y el 52,8% transaminasas elevadas. Los factores asociados a la alteración de las transaminasas fueron: ser hombre OR=4,02 (IC 95%: 2,03-7,96; p50 UI/L OR=7,50 (IC 95%: 3,40-16,56; p<0,01). Los valores de HOMA-IR y GGT fueron significativamente mayores en el grupo de transaminasas altas (p<0,01). Las diferencias en el grado de fibrosis no se asociaron con los niveles de transaminasas. Conclusión: Encontramos que la frecuencia de transaminasas normales fue del 47,2% en pacientes obesos con MASH. Los factores asociados con la elevación de las enzimas hepáticas fueron el sexo masculino, el diagnóstico de diabetes mellitus y la elevación de los niveles de GGT. El grado de fibrosis no se asoció con elevaciones de las transaminasas hepáticas. Estos hallazgos sugieren que los niveles de transaminasas por sí solos no son marcadores precisos para evaluar el daño hepático, ya que no necesariamente se correlacionan con el daño hepático histológico.

Latin American Association for the study of the liver (ALEH) practice guidance for the diagnosis and treatment of non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) currently represents an epidemic worldwide. NAFLD is the most frequently diagnosed chronic liver disease, affecting 20-30% of the general population. Furthermore, its prevalence is predicted to increase exponentially in the next decades, concomitantly with the global epidemic of obesity, type 2 diabetes mellitus (T2DM), and sedentary lifestyle. NAFLD is a clinical syndrome that encompasses a wide spectrum of associated diseases and hepatic complications such as hepatocellular carcinoma (HCC). Moreover, this disease is believed to become the main indication for liver transplantation in the near future. Since NAFLD management represents a growing challenge for primary care physicians, the Asociación Latinoamericana para el Estudio del Hígado (ALEH) has decided to organize this Practice Guidance for the Diagnosis and Treatment of Non-Alcoholic Fatty Liver Disease, written by Latin-American specialists in different clinical areas, and destined to general practitioners, internal medicine specialists, endocrinologists, diabetologists, gastroenterologists, and hepatologists. The main purpose of this document is to improve patient care and awareness of NAFLD. The information provided in this guidance may also be useful in assisting stakeholders in the decision-making process related to NAFLD. Since new evidence is constantly emerging on different aspects of the disease, updates to this guideline will be required in future.

Perfil clínico e inmunológico en 22 pacientes con diagnóstico histopatológico de cirrosis biliar primaria / Clinical and immunological profile in 22 patients with primary biliary cirrhosis

La cirrosis biliar es una entidad poco frecuente en nuestro medio; su diagnóstico se sustenta en hallazgos clínicos, patrón colestásico en las pruebas de función hepatica y la presencia de anticuerpos anti-mitocondriales en el 90 por ciento de los casos y otros autoanticuerpos presentes en el suero, toda esta información esta respaldada por datos histopatológicos hepáticos característicos. También se han descrito algunas formas clínicas que han sugerido denominaciones diferentes como Sindrome de sobreposición (overlap syndrome), asociada a hepatitis autoinmune y la colangitis autoinmune, que se caracteriza por la persistente negatividad de los anticuerpos antimitocondriales. En el presente estudio se reportan los hallazgos clínicos, bioquímicos e inmunológicos de 22 pacientes con diagnóstico histopatológico vistos entre 1994 y 1999, en el Hospital Arzobispo Loayza y la consulta privada. Los resultados mostraron un patrón colestásico en el 100 por ciento de los pacientes, ictericia en el 95 por ciento, prurito en el 86 por ciento, hiperpigmentación de la piel en el 40.9 por ciento, hepatomegalia en 36.9 por ciento, esplenomegalia en 37.3 por ciento y xantelasma en el 36 por ciento; la fosfatasa alcalina estuvo elevada entre 5 y 30 veces los valores normales en todos los pacientes, las transaminasas oxalacética y pirúvica elevada más de dos veces los valores normales en el 95 por ciento y 90 por ciento respectivamente e hipercolesterolemia en el 89 por ciento de los pacientes; los anticuerpos anti mitocondriales fueron positivos en el 64 por ciento, los antinucleares en el 32 por ciento y antimúsculo liso en el 18 por ciento; siete pacientes presentaron enfermedades autoinmunes asociadas, 4 con sindrome seco, 2 con vitiligo y 1 con anemia hemolítica.

[CLINICAL AND IMMUNOLOGICL PROFILE IN 22 PATIENTS WITH PRIMARY BILIARY CIRRHOSIS] / Perfil clínico e inmunológico en 22 pacientes con diagnóstico histopatológico de cirrosis biliar primaria.

The primary biliary cirrhosis (PBC) is a no frequent entity in our country. Its diagnosis is based on clinical features, cholestasic pattern in liver function tests and the presence of antimitochondrial antibody in 90% of cases and other auto-antibodies in the serum, all this information is supported by characteristic hepatic histopathologic data. Also some clinical variants have been described that has suggested different denominations such as Overlap Syndrome, associated to autoimmune hepatitis and autoimmune colangitis, known by its persistent negativity of the antimitochondrials antibodies.The present study reports the clinical, biochemical and immunological findings of 22 patients with histopathologic diagnosis of PBC observed between 1994 and 1999, in Arzobispo Loayza Hospital and private offices, in Lima, Per .Results shown a cholestatic pattern in 100% of patients, jaundice in 95%, pruritus in 86%, hyperpigmentation of skin in 40.9%, hepatomegaly in 36.9% splenomegaly in 37.3% and xantelasma in 36%; alkaline phospatase was increased between 5 and 30 times the normal values in all patients, oxalacetic and piruvic transaminases were increased more than twice the normal values in 95% and 90%, respectively and hypercholesterolemia in 89% of patients; the antimitochondrial antibodies were positive in 64%, antinuclear antibodies in 32% and anti smooth muscle in 18%; 7 patients present associated autoimmune diseases, 4 with sicca syndrome, 2 with vitilige and 1 with hemolitic anemia. Three patients were classified as primary biliary cirrhosis, associated to autoimmune hepatitis; 4 patients died during the follow up and six patients were treated with ursodeoxicholic acid for more than six months.We can conclude that the profile found is a cholestasic pattern with jaundice in the majority of patients, low positivity of mitochondrial antibodies; there was no difference between AMA positive and negative patients, and in the third part of patients it was observed an associated immune disease and in three cases there was evidence of association with autoimmune hepatitis (Overlap Syndrome). Finally, the treatment with ursodeoxicolic acid improves some biochemical parameters, but apparently, they do not survival improve.

Pancreatocolangiografía retrograda endoscópica y esfinterotomía en las parasitosis / Endoscopic retrograde colangio pancreatography and esphinterotomy in parasitic diseases

Presentamos seis pacientes con obstrucción de la vía billar debida a parásitos (Fasciola hepática, Ascaris lumbricoides y quiste hidatídico) que se diagnosticaron y manejaron endoscópicamente. Este es el primer trabajo nacional que resalta la importancia de la pancreatocolangiografía retrógrada endoscópica en el manejo de estas parasitosis. Por otro lado se destaca que no obstante la litiasis coledociana es la causa más común de ictericia extrahepática; debe considerarse a la parasitosis de la vía biliar en el diagnóstico diferencial.

We report six patients with billary duct obstruction due to parasites (Fasciola hepatica, ascarlasis and hydatid cyst) that were diagnosed and managed with the endoscopic approach. This is the first national paper which relevants the importance of endoscopic retrograde cholangio pancreatography in the management of this parasitosis. Despite choledocholithiasis is the most common cause of extrahepatic jaundice, biliary tree parasitosis must be considered in the differential diagnosis.
