Anaemia is often an adverse outcome of severe parasitic infections during pregnancy in developing countries. Pregnant women in malaria-endemic communities are more susceptible to Plasmodium falciparum infections than non-pregnant women of child-bearing age. Objective: To comparatively investigate malaria and anaemia in pregnant and non-pregnant women of child-bearing age. Design: A cross-sectional comparative study. Three hundred and eighty pregnant women and 380 non-pregnant women were screened for the study. Setting: The study was conducted at the University Hospital, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana. Measurements: Participants’ demographic data were collected via the administration of questionnaires. In addition their blood samples were analyzed for haemoglobin level and malaria parasites, while stool samples from the pregnant women were examined for intestinal parasites. Results: The study revealed that pregnant women have higher malaria parasitaemia (12.6%) and anaemia (62.6%). The species of Plasmodium isolated from the pregnant women were P. falciparum (85.4%), P. malariae (4.2%) and P. ovale (10.4%). Malaria parasitaemia was higher in the primigravidae (14%). However multigravidae recorded the highest anaemia prevalence (67.1%). Age of pregnant women was a factor affecting malaria parasitaemia with a significant P-value and OR (P value = 0.0041, 0R = 7.61). Conclusions: Pregnant women were more susceptible to malaria and anaemia than non-pregnant women of child-bearing age. Most of the pregnant women reported at antenatal clinic during the second trimester. Primigravidae however recorded the highest malaria parasitaemia. The main species of Plasmodium observed in the blood samples was falciparum.展开更多

文摘目的分析无创产前基因检测(non-invasive prenatal testing,NIPT)对低危孕妇胎儿染色体异常筛查的临床价值。方法回顾性分析2021年1—12月在茂名市妇幼保健院进行NIPT检查的2541例低危孕妇临床资料,依据孕龄、申请检查原因分组。评价NIPT筛查胎儿染色体异常的效能。结果孕早期阳性检出率为1.85%(10/542),孕中期阳性检出率为1.68%(22/1321),孕晚期阳性检出率为1.18%(8/678);自愿进行NIPT检查组阳性检出率为0.99%(8/811),血清学筛查单项指标或中位数倍数(multiple of median,MOM)值异常组阳性检出率为1.93%(22/1141),B超软指标异常组阳性检出率为1.68%(10/589);2541例孕妇中NIPT检查后提示有40例胎儿染色体异常,阳性检出率为1.63%(40/2541),经过羊膜腔穿刺染色体检查验证后证实有26例胎儿染色体异常,其中13-三体、18-三体、21-三体、其他常染色体非整倍体异常、性染色体、其他分别为1、4、6、5、6、4例,NIPT准确率分别为33.33%、80.00%、85.71%、83.33%、54.55%、50.00%,总准确率为65.00%。结论NIPT筛查低危孕妇中胎儿染色体异常准确率较高,具有较好的筛查效能,且为无创操作,可作为低危孕妇中胎儿染色体异常筛查的辅助检查手段。
