ABSTRACT

Abstract Background: Hemophagocytic lymphohistiocytosis (HLH) is considered a medical emergency that should be recognized in patients with fever, splenomegaly, and progressive deterioration of the general condition. Laboratory findings include cytopenia, hypertriglyceridemia, hypofibrinogenemia, and hyperferritinemia. For HLH diagnosis, it is essential, although not mandatory, to perform a bone marrow biopsy. Given its nature, secondary causes of HLH should be sought, mainly infections, hemato-oncological disorders, autoimmune diseases, and auto-inflammatory conditions. Case report: We present the case of a female adolescent who presented with fever and lower gastrointestinal bleeding. Upon admission, acute liver failure and pancytopenia were documented. A bone marrow aspirate was performed, which revealed hemophagocytosis; other tests confirmed HLH diagnosis. During the diagnostic approach, inflammatory bowel disease was diagnosed. The patient received first-line treatment with an adequate response. Conclusions: Inflammatory bowel disease can be considered a cause of secondary HLH, particularly in patients with suggestive symptoms, such as digestive bleeding in the absence of other secondary causes of HLH.


Resumen Introducción: La linfohistiocitosis hemofagocítica (LHH) es considerada una urgencia médica que debe reconocerse en pacientes con deterioro progresivo del estado general, fiebre, pancitopenia y esplenomegalia. Los hallazgos de laboratorio incluyen citopenia, hipertrigliceridemia, hipofibrinogenemia e hiperferritinemia. Para su diagnóstico es importante, aunque no obligatoria, la realización de aspirado de médula ósea. Dada su naturaleza, se deben buscar causas secundarias de LHH, principalmente enfermedades infecciosas, hematooncológicas, autoinmunitarias y autoinflamatorias. Caso clínico: Se presenta el caso de una adolescente que inició con fiebre y sangrado digestivo bajo. A su ingreso, se documentó falla hepática aguda y pancitopenia. Se realizó aspirado de médula ósea y se encontró hemofagocitocis; el resto de los exámenes concluyeron LHH. Durante su abordaje se diagnosticó enfermedad inflamatoria intestinal. La paciente recibió tratamiento de primera línea con adecuada respuesta. Conclusiones: La enfermedad inflamatoria intestinal puede considerarse como una causa secundaria de LHH, en particular en pacientes con clínica sugestiva, como es el sangrado digestivo, en ausencia de otras causas secundarias de LHH.
