Pancytopenia is an important hematological problem encountered in routine clinical practice associated with a multitude of disease states. The possible causes of pancytopenia can be influenced by geography, socioeconomic conditions, and endemic illnesses. Information regarding the underlying clinical conditions and morphologic features of blood cells of pancytopenia is limited and varied across different regions. Thus, this study was designed to assess the peripheral morphologic features of blood cells and the underlying clinical causes of pancytopenia.
A facility-based cross-sectional study was conducted at the Jimma Medical Center hematology laboratory from June 13 to November 13, 2022. A total of 3 mL of whole blood was collected from each subject for complete blood count analysis and peripheral blood morphology examination. Data on sociodemographic and clinical conditions were collected from medical records using a checklist. The data were analyzed using Statistical Package for the Social Sciences version 26.
A total of 163 patients with pancytopenia were identified within the 5 months. Hyper-reactive malarial splenomegaly was the most prevalent cause (29.4%), followed by megaloblastic anemia (20.2%), chronic liver disease (10.4%), and acute leukemia (8.6%). Anisocytosis was the predominant peripheral blood morphology finding (82.2%), along with microcytosis (49.7%), ovalocytosis (31.3%), and macrocytosis (30.7%). Severe anemia was observed in 57% of cases, whereas the majority (92%) exhibited moderate leukopenia. A significant proportion (42.3%) had a platelet count below 50,000/μL.
Unlike previous studies conducted in other parts of the world, this study showed that hyperreactive malarial splenomegaly was the leading cause of pancytopenia. This emphasizes the necessity of considering this condition as a possible cause for pancytopenia, particularly in malaria-endemic areas. The findings of the hematological profiles and peripheral blood morphology strongly suggest that early identification and prompt management of patients with pancytopenia require collaboration between clinical and laboratory investigations.
全血细胞减少是常规临床实践中遇到的一个重要血液学问题,与多种疾病状态相关。全血细胞减少的可能原因会受到地理位置、社会经济状况和地方病的影响。关于全血细胞减少的潜在临床状况和血细胞形态特征的信息有限,且在不同地区有所差异。因此,本研究旨在评估血细胞的外周形态特征以及全血细胞减少的潜在临床病因。
2022年6月13日至11月13日,在吉马医疗中心血液学实验室开展了一项基于机构的横断面研究。从每位受试者采集3毫升全血,用于全血细胞计数分析和外周血形态学检查。使用清单从病历中收集社会人口统计学和临床状况数据。采用社会科学统计软件包第26版对数据进行分析。
在这5个月内共确定了163例全血细胞减少患者。高反应性疟疾脾肿大是最常见的病因(29.4%),其次是巨幼细胞贫血(20.2%)、慢性肝病(10.4%)和急性白血病(8.6%)。红细胞大小不均是外周血形态学的主要表现(82.2%),同时伴有小红细胞症(49.7%)、椭圆形红细胞症(31.3%)和大红细胞症(30.7%)。57%的病例观察到严重贫血,而大多数(92%)表现为中度白细胞减少。相当一部分(42.3%)患者的血小板计数低于50,000/μL。
与世界其他地区此前开展的研究不同,本研究表明高反应性疟疾脾肿大是全血细胞减少的主要原因。这强调了将该病症视为全血细胞减少可能病因的必要性,尤其是在疟疾流行地区。血液学特征和外周血形态学的研究结果强烈表明,全血细胞减少患者的早期识别和及时管理需要临床和实验室检查之间的协作。
