Peripheral cytopaenias and dyspoiesis are common in cirrhosis; however, the prevalence of dyspoiesis and its contribution in cirrhosis-related cytopaenias has not been studied. We aimed to study the bone marrow (BM) dyspoiesis and its impact on peripheral blood cell counts and refractory anaemia in patients with cirrhosis.
We reviewed all the BM aspirates and biopsies of cirrhotic cases, done from 2011 to 2018 for clinical indications. Dyspoiesis was considered if >5% of the precursor cells of any of the three lineages showed dyspoietic changes. Primary haematological or non-haematological malignancies, chronic kidney disease, drug intake, acute and chronic hepatitis and granulomatous disease were excluded.
Of 608 these, 82 cases (13.5%) showed dyspoiesis in the BM precursors. There was no difference in age (p=0.16), gender (p=0.58) and spleen size (p=0.35) in cases with or without dyspoiesis. Majority of the cases had dyspoiesis in erythroid series (62, 75.6%) and megakaryocytes (15, 18.2%). Dyspoiesis was more prominent in alcoholics 44 cases (53.6%) and autoimmune diseases 13 cases (15.8%). Erythroid hyperplasia (47.7±14.4 vs 40±11.1; p<0.001) was more in cases with dyserythropoiesis, indicating ineffective erythropoiesis. Patients with dyspoiesis had lower haemoglobin (7.5±1.9 vs 9.3±2.2 g/dL, p<0.001). 54 (8.07%) had refractory anaemia with dyspoiesis present in 48 (88.8%) (p<0.01). Dyspoiesis was independently associated with refractory anaemia when adjusted for age, gender, aetiology and liver disease severity.
BM dyspoiesis, especially dyserythropoiesis, is associated with severe refractory anaemia in patients with cirrhosis and requires new therapeutic approaches.
外周血细胞减少和造血异常在肝硬化患者中很常见;然而,造血异常的患病率及其在肝硬化相关血细胞减少中的作用尚未得到研究。我们旨在研究肝硬化患者的骨髓造血异常及其对外周血细胞计数和难治性贫血的影响。
我们回顾了2011年至2018年因临床指征进行的所有肝硬化病例的骨髓穿刺和活检。如果三个谱系中任何一个谱系的>5%的前体细胞出现造血异常变化,则认为存在造血异常。排除原发性血液系统或非血液系统恶性肿瘤、慢性肾脏病、药物摄入、急慢性肝炎和肉芽肿性疾病。
在这608例患者中,82例(13.5%)骨髓前体细胞出现造血异常。有或无造血异常的患者在年龄(p=0.16)、性别(p=0.58)和脾脏大小(p=0.35)方面无差异。大多数病例的红系(62例,75.6%)和巨核细胞(15例,18.2%)存在造血异常。造血异常在酒精性肝病患者中更为突出,有44例(53.6%),在自身免疫性疾病患者中有13例(15.8%)。红系增生在有红细胞生成异常的病例中更为明显(47.7±14.4对40±11.1;p<0.001),表明红细胞生成无效。有造血异常的患者血红蛋白水平较低(7.5±1.9对9.3±2.2 g/dL,p<0.001)。54例(8.07%)患有难治性贫血,其中48例(88.8%)存在造血异常(p<0.01)。在对年龄、性别、病因和肝病严重程度进行校正后,造血异常与难治性贫血独立相关。
骨髓造血异常,尤其是红细胞生成异常,与肝硬化患者的严重难治性贫血有关,需要新的治疗方法。
