Distribution of malaria and intestinal helminths is known to overlap in developing tropical countries of the world. Co-infections with helminth and malaria parasites cause a significant and additive problem against the host. The aim of this study was to asses the prevalence of malaria/helminth co-infection and the associated problems among febrile outpatients that attended Alaba Kulito Health Center, southern Ethiopia November and December 2007. A total of 1802 acute febrile patients were diagnosed for malaria. 458 Giemsa-stained thick and thin blood films were used for identification of Plasmodium species and Stool samples prepared using Kato-Katz technique were used to examine for intestinal helminths. Haemoglobin concentration was measured using a portable spectrophotometer (Hemocue HB 201). Anthropometry-based nutritional assessment of the study participants was done by measuring body weight to the nearest 0.1 kg and height to the nearest 0.1 cm.
458 of the total febrile patients were positive for malaria. Co infection with Plasmodium and helminth parasites is associated with significantly (p < 0.001) higher anaemia prevalence than single infection with Plasmodium parasites. And this difference was also significant for haemoglobin concentration (F = 10.18, p = 0.002), in which patients co infected with Plasmodium and helminth parasites showed lower mean haemoglobin concentration. More than one-third of the infected cases in both malaria infections and malaria/helminth co infections are undernourished. However the statistics for the difference is not significant.
Malaria and soil-transmitted helminthiasis obviously contribute to anaemia and low weight status and these conditions are more pronounced in individuals concurrently infected with malaria and soil-transmitted helminths. Hence, simultaneous combat against the two parasitic infections is very crucial to improve health of the affected communities.
在世界上热带发展中国家,疟疾和肠道蠕虫的分布已知存在重叠。蠕虫与疟原虫的共同感染给宿主带来了一个严重的叠加问题。本研究的目的是评估2007年11月和12月在埃塞俄比亚南部阿拉巴·库利托健康中心就诊的发热门诊患者中疟疾/蠕虫共同感染的患病率及相关问题。共对1802例急性发热患者进行了疟疾诊断。使用458份吉姆萨染色的厚薄血涂片来鉴定疟原虫种类,并用加藤-厚涂片技术制备的粪便样本检查肠道蠕虫。使用便携式分光光度计(Hemocue HB 201)测量血红蛋白浓度。通过将研究参与者的体重精确测量到最接近的0.1千克、身高精确测量到最接近的0.1厘米,基于人体测量学对研究参与者进行营养评估。
在所有发热患者中,458例疟疾检测呈阳性。疟原虫与蠕虫寄生虫的共同感染导致贫血患病率显著高于单纯疟原虫感染(p < 0.001)。血红蛋白浓度方面差异也显著(F = 10.18,p = 0.002),疟原虫与蠕虫寄生虫共同感染的患者平均血红蛋白浓度较低。在疟疾感染和疟疾/蠕虫共同感染的病例中,超过三分之一的感染者营养不良。然而,差异的统计学意义不显著。
疟疾和土壤传播的蠕虫病显然会导致贫血和低体重状况,这些情况在同时感染疟疾和土壤传播蠕虫的个体中更为明显。因此,同时对抗这两种寄生虫感染对于改善受影响社区的健康状况非常关键。
