ABSTRACT

Resumen Paciente mujer de 55 años con antecedente de crioglobulinemia mixta con compromiso renal glomerulonefritis membranoproliferativa, enfermedad renal crónica (ERC) en estadio G5, presenta cuadro de ictericia, coluria los exámenes complementarios muestran incremento de las pruebas hepáticas con hipertransaminasemia, hiperbilirrubinemia y colestasis, serologías hepáticas virales negativas, anticuerpo antimitocondrial (AMA) +, se realiza biopsia hepática identificando hepatitis de interfase y en el interior de los septos fibrosos, reacción ductal focal y leve proliferación de ramas de la vena porta que están distorsionadas entre gruesas fibras de colágeno, llegando al diagnóstico de síndrome de superposición, se inicia tratamiento con corticoides 1 mgr/Kgr/día y ácido ursodeoxicólico 13 mgr/kgr/día con buena evolución, logrando normalizar las enzimas hepáticas. Ambas patologías "crioglobulinemia mixta y hepatopatías autoinmunes", son entidades poco frecuentes que presentan buenas respuestas al tratamiento inmunosupresor e inmunomodulador.


Abstract A 55-year-old female patient with a history of mixed cryoglobulinemia with renal involvement, membranoproliferative glomerulonephritis, chronic kidney disease (CKD) stage G5, presented with jaundice, choluria, complementary examinations showed increased liver tests with hypertransaminasemia, hyperbilirubinemia and cholestasis, negative viral liver serologies, anti-mitochondrial antibody (AMA) +, a liver biopsy was performed identifying interphase hepatitis and in the interior of the fibrous septa, focal ductal reaction and slight proliferation of branches of the portal vein which are distorted between thick collagen fibres, leading to the diagnosis of overlap syndrome, treatment was started with corticosteroids 1 mg/Kg/day and ursodeoxycholic acid 13 mg/kg/day with good evolution, achieving normalization of liver enzymes. Both pathologies "mixed cryoglobulinemia and autoimmune hepatopathies" are rare entities that respond well to immunosuppressive and immunomodulatory treatment.
