Correlation between CD 34 and CD 68 expression in placental malaria with maternal anemia.

Background: Malaria is the second most life-threatening infectious disease in Indonesia, causing approximately 1-3 million deaths annually. Histopathologic studies assessing CD 68 and CD 34 protein expression in placental malaria and its association with maternal anemia are essential to determine the prognosis of malaria in pregnancy.

Materials and methods: This cross-sectional study was carried out in 2017. Thirty biopsy samples of human placental tissue were obtained from Timika and Sumba, and ten normal biopsy samples were taken from the Pathological Anatomy Department of Cipto Mangunkusumo General Hospital as comparisons. CD 34 and CD 68 protein expressions were determined using immunohistochemistry, and the resulting data were analyzed using SPSS.

Results: Average hemoglobin (Hb) level was 9.5 mg/dL, 11.5 mg/dL, and 9.9 mg/dL in acute infection, chronic infection, and latent infection, respectively. A positive correlation was found between CD 68 protein expression and maternal Hb level. No correlation was found between CD34 expression and maternal anemia.

Conclusions: CD 68 expression in placental tissue biopsy from Timika and Sumba residents with placental malaria was shown to be positively correlated with maternal anemia. Immunohistochemical examination of CD 68 may play a role in the early diagnosis of malaria.
