BACKGROUND AND AIM: Certain thrombocytopenic patients with chronic liver disease have inadequate platelet count recovery after platelet transfusion or lusutrombopag administration. We aimed to identify the reasons for this phenomenon. METHODS: We investigated 58 and 86 thrombocytopenic patients with chronic liver disease who received lusutrombopag (3 mg orally for up to 7 days) or underwent blood transfusions, respectively. Thirty patients underwent simultaneous hepatic surgery and splenectomy. Factors preventing platelet count recovery above 50 × 103 /μL were identified. RESULTS: The median patient age was 64 years. Eleven, 78, and 55 patients had hepatitis B, hepatitis C, or another etiology, respectively; 59, 69, and 16 had Child-Pugh classes A, B, and C, respectively. The median spleen volume was 432 mL, and a median of 10 blood units were transfused per patient. The median platelet count rose significantly (from 41.5 × 103 /μL to 81.0 × 103 /μL) after lusutrombopag administration but not after blood transfusion before invasive procedures. However, maximum platelet counts in patients who underwent splenectomy before platelet transfusion were markedly improved over those who did not. Increasing platelet counts above 50 × 103 /μL required baseline platelets > 30 × 103 /μL and lusutrombopag administration for all patients. Platelet count recovery was dependent on a spleen volume of < 300 mL and baseline platelets of > 40 × 103 /μL in patients who underwent platelet transfusions, while a baseline platelet count of > 30 × 103 /μL was required for patients administered with lusutrombopag. CONCLUSION: Neither blood transfusion nor lusutrombopag improves thrombocytopenia in patients with severe conditions; however, the degree of platelet count elevation following lusutrombopag administration is higher than that following blood transfusion.
