Banked blood is a limited resource in Nigeria. We sought to evaluate factors that may further limit the effective utilisation of donor blood in a tertiary hospital in Benin City. The records of the blood transfusion unit of the hospital were studied to identify the methods of blood procurement and utilisation from January 1, 2000 to December 31, 2002. A total of 11,021 units of blood were received in the blood transfusion unit within this period out of which 1491 (13.5%) donor blood samples were found unfit for transfusion and, hence, discarded. Commercial blood donation accounted for 95.3%, compared to 4.7% from replacement and volunteer donors. Commercial blood donation was a major risk factor for likely disposal of donor blood (x 2 = 74.3, p < 0.0001, OR = 21.1, 95% CI = 7.8-56.7). Expired units of blood with low PCV were discarded for lack of infrastructure to fractionate and store them. Over N 0.8million (US$6000.00) is wasted annually on discarded units of donor blood mainly from commercial donors. A policy on blood procurement to include subgroup selection of donors and improved funding of blood banking services may enhance efficient and effective utilisation of donor blood.

In a prospective study using standard methods, haemorheological parameters were assessed in 10 sickle cell anaemia patients in pain crises. Patients were investigated for possible changes in determinants of rheology in the course of painful episodes: blood samples were taken for plasma fibrinogen concentration (PFC); plasma viscosity (PV); haematocrit (Hct), whole blood viscosity (WBV) and the erythrocyte sedimentation rate (ESR) using standard methods. Samples were collected on presentation to the emergency unit and daily for 4 consecutive days. Whole blood viscosity and plasma fibrinogen concentration were significantly higher at onset of crises when compared with baseline values (p < 0.01 and p < 0.0001), respectively. Plasma fibrinogen and blood viscosity peaked within 24 h of onset of crisis and started declining 48-72 h later. These parameters approached baseline values by the 4th day of painful crisis.There was no significant change in the haematocrit and the erythrocyte sedimentation rate during the period of painful crisis despite change in whole blood viscosity and fibrinogen. In conclusion, this study showed elevated haemorheological parameters in sickle cell anaemia patients in VOC, it also demonstrated an acute rise in these parameters at onset of crisis and a return to almost baseline levels within 96 h of onset of painful episodes.

Although the campaign against HIV has been intensive, it has been focused mainly on the public health implications. Little or no attention is specifically directed at encouraging the public to know their HIV serostatus. The actual public health burden due to this infection is therefore not known. Accurate data on the health burden is critical for national planning on preventive and other interventional measures. Using a semi-structured self-administered questionnaire, we interviewed 1051 women seeking induced abortion in four randomly selected private clinics in Benin City between January and September 2002. The blood samples of those who accepted HIV testing were collected and screened at the University of Benin Teaching Hospital. The women were aged between 16 and 46 years (mean 31.1 ± 6.7 years). One hundred and thirty seven women (13%) accepted HIV testing. Of the 1051 women, 1001 (95.2%) had multiple sexual partners and 722 (68.8%) regularly practiced unprotected sex. All were aware of HIV/ AIDS. The older women were more likely to accept voluntary HIV testing than the younger ones. Acceptance rate for voluntary HIV testing was low in both the employed and unemployed and much lower among full time housewives (p = 0.01). We therefore recommend that HIV campaign programmes should include strategies aimed at arousing public interest in voluntary HIV testing.

Qouique la campagne contre le VIH ait été intensive, elle a été concentré surtout sur les implications sur la santé publique. Pratiquement très peu d'attention a été consacrée à l'encouragement du public à connaître leur situation sérologique du VIH. Ainsi, le vrai degré du problème de la santé publique causé par cette infection n'est pas connu. Des données précises sur le problème de la santé sont critiques pour la planification nationale en ce qui concerne des mesures préventives et interventionnelles.
