Deferral patterns of voluntary blood donors at the National Blood Transfusion Service, North East Zonal Centre, Maiduguri.

Appropriate donor selection in an important step in ensuring safe supply of blood and blood products. In this study deferral patterns of voluntary non-renumerated blood donors were determined at the North-Eastern Zonal Centre of the National Blood Transfusion service. The study was conducted between April 2007 and April 2009, and it involved the administration of a structured questionnaire. A total of 4032 voluntary blood donors were recruited, seven hundred and thirteen (17.7%) were temporarily deferred. The commonest reasons for deferral were low haemoglobin, self-deferral, high blood pressure, low weight and high risk behaviour. Other reasons are use of certain medications, low blood pressure and failed venopuncture. Gender analysis showed that more females were deferred for low haemoglobin and more males were self-deferred. Following donor recall, 146 of the 173 donors temporarily deferred came back to donate. These consisted of 113 deferral due to low haemoglobin, 30 self-deferred and 3 induced in risky behaviour. Effective education or counseling, the old tradition of giving haematinics and good dietary advice to those with low haemaglobin values, improved the safety and availability of blood and blood products. Donors who are self-deferred and those involved in high risk bahviour should never be persuaded to donate blood. There is also the need for a review of operational guidelines with regards the uniform acceptable cutoff point of 12.5g/dl haemoglobin value for males and females.

Prevalence, risk factors and effects of placental malaria in the UMTH, Maiduguri, North-eastern, Nigeria: a cross-sectional study.

SUMMARY: Most of the adverse effects of malaria in pregnancy on the fetus are usually as a consequence of placental malaria (PM). This study was conducted with the objective of determining the prevalence, risk factors and pregnancy outcome of PM. A cross-sectional study of 437 pregnant women who delivered at the UMTH, Maiduguri was conducted between 24 July 2007 and 12 January 2008. Placental histology was done for the malaria parasite. Maternal packed cell volume was done and thick blood films were studied for the malaria parasite in maternal peripheral blood and the cord blood/heel prick of their babies. The prevalence of PM was 33.9% (148/437). It is associated with non-usage of intermittent preventive treatment of malaria in pregnancy (IPT) and maternal HIV infection. PM in turn predisposes to low birth weight and cord parasitaemia. Only 2.8% of the women were sleeping under insecticide-treated nets (ITNs). The high prevalence of PM calls for renewed efforts for preventive measures, particularly the routine use of IPT and ITN during the antenatal period.
