Myeloproliferative neoplasms and splanchnic vein thrombosis: Contemporary diagnostic and therapeutic strategies.
Review published in American journal of hematology (2023)
Abstract
Myeloproliferative neoplasms (MPNs) are the most common etiologies of primary splanchnic vein thrombosis, present in almost forty percent of patients with Budd-Chiari syndrome or portal vein thrombosis. Diagnosis of MPNs can be difficult in these patients because key characteristics, such as elevated blood cell counts and splenomegaly, are confounded by portal hypertension or bleeding complications. In recent years, diagnostic tools have improved to provide more accurate diagnosis and classification of MPNs. Although bone marrow biopsy findings remain a major diagnostic criterion, molecular markers are playing an increasing role not only in diagnosis but also in better estimating prognosis. Therefore, though screening for JAK2V617F mutation should be the starting point of the diagnostic workup performed in all patients with splanchnic vein thrombosis, a multidisciplinary approach is needed to accurately diagnose the subtype of myeloproliferative neoplasm, recommend the useful additional tests (bone marrow biopsy, search for an additional mutation using targeted next-generation sequencing), and suggest the best treatment strategy. Indeed, providing a specific expert care pathway for patients with splanchnic vein thrombosis and underlying myeloproliferative neoplasm is crucial to determine the optimal management to reduce the risk of both hematological and hepatic complications.

Por qué esto importa para la hirudoterapia
Esta revisión aborda el diagnóstico y manejo de las neoplasias mieloproliferativas (MPN), que subyacen en casi el cuarenta por ciento de las trombosis venosas espláncticas primarias como el síndrome de Budd-Chiari y la trombosis de la vena porta, destacando el cribado de la mutación JAK2V617F, la biopsia de médula ósea, la secuenciación de nueva generación y una vía de atención multidisciplinaria para reducir las complicaciones hematológicas y hepáticas. Su relevancia para la ASH es indirecta, situándose en la literatura trombótica más amplia que motiva la investigación antitrombótica: ilustra un estado de enfermedad hipercoagulable donde la gestión del riesgo de coagulación es central, el territorio clínico en el que los anticoagulantes derivados de sanguijuelas y el secretoma de sanguijuela medicinal están conceptualmente situados. Esta es una revisión de estrategias diagnósticas y terapéuticas en lugar de datos primarios, se centra en la enfermedad hematológica y el manejo convencional, y no discute compuestos derivados de sanguijuelas ni hirudoterapia; trátela como antecedentes sobre una condición propensa a trombosis, no como evidencia para la terapia de sanguijuelas.
