Liat Mlynarsky, MD Case presentation 68 y/o woman Presents to the E.R with massive hematemesis Past medical history: 2003 – Vagotomy & pyloroplasy d/t PUD 1996 – Dx with polycythemia vera, JAK2 positive Long time ago - Appendectomy Case presentation Primary evaluation 137/97, pulse 92bpm, Sat. 98%RA Pale Abdomen – soft, non-tender, enlarged spleen PR- normal stool NG – fresh blood Lab results: Hb-11.3 (basic-13.5), Plt-147,000 INR-1.3 Upper GI endoscopy Triple-Phase Abdominal CT Triple-Phase Abdominal CT Further investigation AST-21 HBV ALT-25 HCV AP- 51 HIV GGT- 45 ANA Bil.- 0.6 AMA Alb - 37 ASMA Globulin - 17 LKM Liver-spleen US Elastography Spleen Elastography 48 kPA Liver Elastography 6.6 kPA = F1 Webb et al: Assessment of liver and spleen stiffness in patients with myelofibrosis using Fibroscan and Shear Wave Elastography- 2015 Hematologic evaluation Polycythemia vera MDS/Myelofibrosis CBC – normal/ near normal No indication for disease specific treatment Meanwhile… In 6 weeks – recurrent admission Melena 3rd upper endoscopy with histoacryl injection Summary Recurrent bleeding from isolated gastric varices Huge spleen d/t MPD No apparent signs of liver disease Non-cirrhotic Portal Hypertension Non-cirrhotic PHT – HVPG is normal/mildly elevated and is significantly lower than PV pressure Non-cirrhotic portal hypertension – Diagnosis and management. Rajeev, K. et al. Journal of Hepatology 2014 vol. 60 j 421–441 Banti’s syndrome In 1894, G.Banti : splenomegalic anaemia cirrhosis Banti's syndrome. Hypersplenism, cytopenias and portal hypertension without portal vein obstruction or significant liver disease Variceal bleeding - common Ascites, jaundice, and encephalopathy - rare Idiopathic? Toxic? Immunologic? Banti’s syndrome Currently AKA: Non-cirrhotic portal hypertension Idiopathic portal hypertension Hepatoportal sclerosis Non-cirrhotic portal fibrosis? Left-sided portal hypertension? Polycethemia Vera & the liver PV - low EPO and JAK2 mutation Portal hypertension is found in up to 5-10% of patients Possible mechanisms : Prothrombotic and hyperviscous state: Budd chiari syndrome / Portal vein thrombosis Nodular Regenerative Hyperplasia (NRH) Extramedullary hematopoiesis Splenomegaly Marvin M. Singh, MD, Paul J. Pockros. Hematologic and Oncologic Diseases and the Liver. Clin Liver Dis 15 (2011) 69–87 Endoscopic treatment Timing - Patients with GI bleeding and features suggesting cirrhosis should have upper endoscopy as soon as possible after admission (within 12 h) (5;D) IGV1: Glue injection with N-butyl-cyanoacrylate Repeated at 2–3 weekly intervals until eradication Prophylaxis - Despite lack of data, patients with gastric varices may be treated with NSBB (5;D). Shunt - Angiographic TIPS – HVPG < 12mmHg after TIPS prevents bleeding from esophageal variceal but not necessarily from gastric varices Shunt - Surgical Proximal splenorenal shunt with Distal splenorenal shunt (DSRS) splenectomy End-to-side porto-caval shunt Meso-caval shunt Spleen reduction in MPD Splenic artery embolization Radiotherapy Splenectomy Ruxolitinib (Jakavi) The first JAK inhibitor to gain approval In randomized Phase III trials - Reduction in spleen volume (>35%): at 24 weeks in 41.9% vs 0.7% placebo; P<0.0001 ~70% maintained their response for 48 weeks AEs - anemia and thrombocytopenia Responses to ruxolitinib are typically observed within the first 3–6 months after therapy initiation Back to our patient… Following multidisciplinary discussions: Plan A! – Jakavi If fails… Plan B – Liver biopsy & HVPG TIPS/splenectomy/other?
