Placental malaria in pregnant women using ITN/LLIN and IPT as control measures in three selected towns in southeast Nigeria

In recent years ITN/LLIN and IPT have been considered appropriate measures to help reduce or prevent Malaria infections in pregnant women. This study was carried out on 844 pregnant women in Afikpo, Okigwe and Umuahia towns of Southeast Nigeria to evaluate the role of ITN/LLIN and IPT in Malaria control. The Placentas of consenting women were obtained post delivery (following Ethical clearance by relevant authorities) and histological sections were prepared, stained and observed under the microscope for Plasmodium parasites. Of the 844 women examined, 225 (26.7%) used ITN/LLIN, 276 (32.7%) used IPT while 343 (40.6%) used other measures. The ITN/LLIN group had 36.9% infection with 83 of 225 infected. The IPT group had 39.1% infection with 108 of 276 infected while those who used other measures had 216 0f 343 (63%) infected. The difference between the ITN/IPT group and the other measures group was statistically significant (P<0.05). There was also variations between the towns with Okigwe having the lowest infection of 27.3% among those using ITN/LLIN and IPT while Umuahia had the highest, 48.3% with ITN/ LLIN and 70.8% with IPT. The significance of these results was discussed in relation to Malaria in pregnancy.
