Abstract
The clinical severity of sickle cell disease (SCD) is strongly influenced by the level of fetal haemoglobin (HbF) persistent in each patient. Three major HbF loci (BCL11A, HBS1L-MYB, and Xmn1-HBG2) have been reported, but a considerable hidden heritability remains. We conducted a genome-wide association study for HbF levels in 1006 Nigerian patients with SCD (HbSS/HbSβ0), followed by a replication and meta-analysis exercise in four independent SCD cohorts (3,582 patients). To dissect association signals at the major loci, we performed stepwise conditional and haplotype association analyses and included public functional annotation datasets. Association signals were detected for BCL11A (lead SNP rs6706648, β = -0.39, P = 4.96 × 10-34) and HBS1L-MYB (lead SNP rs61028892, β = 0.73, P = 1.18 × 10-9), whereas the variant allele for Xmn1-HBG2 was found to be very rare. In addition, we detected three putative new trait-associated regions. Genetically, dissecting the two major loci BCL11A and HBS1L-MYB, we defined trait-increasing haplotypes (P < 0.0001) containing so far unidentified causal variants. At BCL11A, in addition to a haplotype harbouring the putative functional variant rs1427407-'T', we identified a second haplotype, tagged by the rs7565301-'A' allele, where a yet-to-be-discovered causal DNA variant may reside. Similarly, at HBS1L-MYB, one HbF-increasing haplotype contains the likely functional small indel rs66650371, and a second tagged by rs61028892-'C' is likely to harbour a presently unknown functional allele. Together, variants at BCL11A and HBS1L-MYB SNPs explained 24.1% of the trait variance. Our findings provide a path for further investigation of the causes of variable fetal haemoglobin persistence in sickle cell disease.

Abstract
BACKGROUND Anaemia during pregnancy causes adverse outcomes to the woman and the foetus, including anaemic heart failure, prematurity, and intrauterine growth restriction. Iron deficiency anaemia (IDA) is the leading cause of anaemia and oral iron supplementation during pregnancy is widely recommended. However, little focus is directed to dietary intake. This study estimates the contribution of IDA among pregnant women and examines its risk factors (including dietary) in those with moderate or severe IDA in Lagos and Kano states, Nigeria. METHODS In this cross-sectional study, 11,582 women were screened for anaemia at 20-32 weeks gestation. The 872 who had moderate or severe anaemia (haemoglobin concentration < 10 g/dL) were included in this study. Iron deficiency was defined as serum ferritin level < 30 ng/mL. We described the sociodemographic and obstetric characteristics of the sample and their self-report of consumption of common food items. We conducted bivariate and multivariable logistic regression analysis to identify risk factors associated with IDA. RESULTS Iron deficiency was observed among 41% (95%CI: 38 - 45) of women with moderate or severe anaemia and the prevalence increased with gestational age. The odds for IDA reduces from aOR: 0.36 (95%CI: 0.13 - 0.98) among pregnant women who consume green leafy vegetables every 2-3 weeks, to 0.26 (95%CI: 0.09 - 0.73) among daily consumers, compared to those who do not eat it. Daily consumption of edible kaolin clay was associated with increased odds of having IDA compared to non-consumption, aOR 9.13 (95%CI: 3.27 - 25.48). Consumption of soybeans three to four times a week was associated with higher odds of IDA compared to non-consumption, aOR: 1.78 (95%CI: 1.12 - 2.82). CONCLUSION About 4 in 10 women with moderate or severe anaemia during pregnancy had IDA. Our study provides evidence for the protective effect of green leafy vegetables against IDA while self-reported consumption of edible kaolin clay and soybeans appeared to increase the odds of having IDA during pregnancy. Health education on diet during pregnancy needs to be strengthened since this could potentially increase awareness and change behaviours that could reduce IDA among pregnant women with moderate or severe anaemia in Nigeria and other countries.

Abstract
Background Anaemia in pregnancy is highly prevalent in African countries. High-dose oral iron is the current recommended treatment for pregnancy-related iron deficiency anaemia (IDA) in Nigeria and other African countries. This oral regimen is often poorly tolerated and has several side effects. Parenteral iron preparations are now available for the treatment of IDA in pregnancy but not widely used in Africa. The IVON trial is investigating the comparative effectiveness and safety of intravenous ferric carboxymaltose versus oral ferrous sulphate standard-of-care for pregnancy-related IDA in Nigeria. We will also measure the implementation outcomes of acceptability, feasibility, fidelity, and cost-effectiveness for intravenous ferric carboxymaltose. Methods This is an open-label randomised controlled trial with a hybrid type 1 effectiveness-implementation design, conducted at 10 health facilities in Kano (Northern) and Lagos (Southern) states in Nigeria. A total of 1056 pregnant women at 20–32 weeks’ gestational age with moderate or severe anaemia (Hb < 10g/dl) will be randomised 1:1 into two groups. The interventional treatment is one 1000-mg dose of intravenous ferric carboxymaltose at enrolment; the control treatment is thrice daily oral ferrous sulphate (195 mg elemental iron daily), from enrolment till 6 weeks postpartum. Primary outcome measures are (1) the prevalence of maternal anaemia at 36 weeks and (2) infant preterm birth (<37 weeks’ gestation) and will be analysed by intention-to-treat. Maternal full blood count and iron panel will be assayed at 4 weeks post-enrolment, 36 weeks’ gestation, delivery, and 6 weeks postpartum. Implementation outcomes of acceptability, feasibility, fidelity, and cost will be assessed with structured questionnaires, key informant interviews, and focus group discussions. Discussion The IVON trial could provide both effectiveness and implementation evidence to guide policy for integration and uptake of intravenous iron for treating anaemia in pregnancy in Nigeria and similar resource-limited, high-burden settings. If found effective, further studies exploring different intravenous iron doses are planned. Trial registration ISRCTN registry ISRCTN63484804. Registered on 10 December 2020 Clinicaltrials.govNCT04976179. Registered on 26 July 2021 The current protocol version is version 2.1 (080/080/2021).

Abstract
Background Coagulation abnormality is a significant complication and cause of mortality in children with uncorrected congenital heart defects (CHD). The aim of this study was to determine the prevalence of coagulation abnormalities and the associated factors in children with uncorrected CHD. Method A cross sectional study conducted to determine the prevalence of coagulation abnormalities among 70 children with uncorrected CHD aged six months to 17 years and 70 age and sex matched apparently healthy controls. Coagulation abnormalities was determined using complete blood count, prothrombin time, activated partial thromboplastin time and D-dimer assay. Results The prevalence of coagulation abnormalities among children with CHD and controls was 37.1% and 7.1% respectively. Children with Cyanotic CHD had a significantly higher prevalence of coagulation abnormalities compared to children with Acyanotic CHD (57.1% versus 17.1%). Haematocrit and oxygen saturation levels were significantly associated with coagulation abnormalities. Conclusion This study affirms that coagulation abnormalities are frequent in children with uncorrected CHD. Oxygen saturation and haematocrit are risk factors of coagulation abnormalities. Routine coagulation screen is recommended especially in children with cyanotic congenital heart defects to improve their quality of life and reduce morbidity and mortality while awaiting definitive surgeries.

Abstract
INTRODUCTION The evidence of benefits for prophylaxis especially low dose prophylaxis is incontestable yet most children in developing countries as Nigeria do not have access to this treatment protocol. AIM The aim was to audit the low dose prophylaxis treatment in Nigerian children with haemophilia. METHODOLOGY A multicentre clinical audit of five haemophilia treatment centres; University of Nigeria Teaching Hospital Enugu, Lagos University Teaching Hospital, National Hospital Abuja, University of Port Harcourt Teaching Hospital Port Harcourt, and Federal Teaching Hospital Gombe. Eighteen children with mild-severe haemophilia were enrolled into low-dose prophylaxis treatment programme. The reduction of joint bleeding, improvement of joint function and Quality of Life (QoL) during prophylaxis were analysed. RESULTS In total 18 children - 17males and 1 female (median age 8 years) were enrolled. The median duration of observation was 7 months (range 3-15months). Seven of the children were on primary prophylaxis (41%) while 10 of the children (59%) were on secondary prophylaxis. The number of joint bleeds decreased from a total of 162 (individual range 5-20, mean 10.3) to 42 (range 0-7, mean 3.0) during the observation period with an overall reduction of 74%. Joint function improved in 94.1% of disease joints, while only 5.6% reported no improvement (due to poor compliance). School attendance improved in all subjects, sports participation and daily activity improved moderately. CONCLUSION Low dose prophylaxis was beneficial in reduction of joint bleeds, improvement of joint function and improvement of QoL of Children with haemophilia in Nigeria.

Abstract
Sickle cell disease (SCD) poses a major public health challenge in sub-Saharan Africa, including Nigeria. Blood transfusion is a mainstay in SCD treatment. Erythrocyte alloimmunization is known to complicate the transfusional care of patients with SCD. Immune alloantibodies are associated with hemolytic transfusion reactions and transfusion refractoriness. We aimed to determine the prevalence, specificities, and clinical associations/risk factors of immune erythrocyte alloantibodies among adult patients with SCD compared with healthy blood donors in Lagos, Nigeria, through a cross-sectional study. All participants were interviewed using a structured questionnaire to obtain details on bio-data, hemoglobin phenotype, blood transfusion history, and SCD history where relevant. Blood specimens obtained from each participant were subjected to antibody screening/identification using tube agglutination method. The mean age of the SCD participants and healthy blood donors was 27.92 and 29.04 years, respectively. The majority (72.5%) of the SCD participants had received at least 1 unit of red blood cell (RBC) transfusion in their lifetime, compared with only 7.5 percent of blood donors. Six SCD participants (7.5%) tested positive for atypical erythrocyte alloantibodies, with none among blood donors. Most of the antibodies (75%) belonged to the Rh blood group system. The most frequent antibody was anti-E, followed by anti-C and anti-D. Advancing age (30 years or more), recent transfusions (last 4 weeks), higher transfusion rates, and established renal disease were significantly associated with alloimmunization (p values of 0.026, 0.043, 0.002, and 0.043, respectively). This study suggests blood transfusion as a strong risk factor for RBC alloimmunization in SCD patients. Extended RBC phenotyping is recommended for all patients with SCD, especially those receiving regular transfusions. Sickle cell disease (SCD) poses a major public health challenge in sub-Saharan Africa, including Nigeria. Blood transfusion is a mainstay in SCD treatment. Erythrocyte alloimmunization is known to complicate the transfusional care of patients with SCD. Immune alloantibodies are associated with hemolytic transfusion reactions and transfusion refractoriness.

Abstract
Background HIV is a chronic inflammatory state with the production of many acute-phase-reactant proteins. Some of these proteins have procoagulant activities that predispose HIV-infected patients to thrombosis. Objectives The aim of the study was to evaluate the effects of HIV infection on the serum levels of C4b-binding protein (C4BP) and protein S as markers of predisposition to thrombosis in HIV-infected adults. Methods The study population comprised of 61 HIV-infected adults on antiretroviral treatment (ART) who had achieved virological suppression, 58 HIV-infected adults not yet on ART and 59 HIV-negative healthy controls. The serum levels of free protein S, C4BP and the euglobulin clot lysis time (ECLT) were determined. Results The mean plasma-free protein S level of HIV-infected patients on ART (86.9% ± 25.8%) was significantly higher than that of treatment-naïve HIV-infected patients (75.7% ± 27.3%) (p = 0.005). Conversely, there was no statistically significant difference between the protein S levels of the HIV-infected subjects on ART (86.9% ± 25.8%) and those of the controls (94.9% ± 7.9%) (p = 0.119). The mean C4BP was significantly higher in the treatment-naïve HIV-infected subjects (36.7 ± 1.7 ng/dL) than that in those on ART (30.7 ± 2.6 ng/dL) and that in the controls (22.4 ± 2.4 ng/dL) (p < 0.0001). Protein S deficiency was more prevalent among the subjects with elevated C4BP (p = 0.023). The mean ECLT was significantly more prolonged in the treatment-naïve HIV-infected subjects (241.9 ± 34.7 s) than controls (189.5 ± 40.7 s) (p < 0.0001). Conclusion HIV infection causes elevated levels of C4BP and diminishes the serum levels of free protein S. We infer that the risk of thrombosis (as measured by these biomarkers) decreases with the use of antiretroviral drugs.

Abstract
Understanding the interplay of genetic factors with haemoglobin expression and pathological processes in sickle cell disease is important for pharmacological and gene-therapeutic interventions. In our nascent study cohort of Nigerian patients, we found that three major disease-modifying factors, HbF levels, α-thalassaemia deletion and BCL11A genotype, had expected beneficial haematological effects. A key BCL11A variant, while improving HbF levels (5.7%-9.0%), also led to a small, but significant decrease in HbA2. We conclude that in general, interventions boosting HbF are likely to reduce HbA2 in patients' erythroid cells and that such therapeutic strategies might benefit from a parallel stimulation of HbA2 through independent mechanisms.

Abstract
In Nigeria, about 150000 babies are born annually with sickle cell disease (SCD), and this figure has been estimated to increase by 100% by the year 2050 without effective and sustainable control strategies. Despite the high prevalence, newborn screening for SCD which allows for early prophylactic treatment, education of parents/guardians and comprehensive management is not yet available. This study explored a strategy for screening in early infancy during the first and second immunization visits, determined the prevalence, feasibility and acceptability of early infant screening for SCD and the evaluation of the HemoTypeSC diagnostic test as compared to the high-performance liquid chromatography (HPLC) gold standard. A cross-sectional study was conducted in two selected primary health care centres in Somolu local government area (LGA) in Lagos, Nigeria. Two hundred and ninety-one mother-infant pairs who presented for the first or second immunization visit were consecutively enrolled in the study following written informed consent. The haemoglobin genotype of mother-infant pairs was determined using the HemoTypeSC rapid test kit. Confirmation of the infants’ Hb genotype was done with HPLC. Data were analysed with SPSS version 22. Validity and Predictive value of HemotypeSC rapid screening test were also calculated. Infant screening for SCD was acceptable to 86% of mothers presenting to the immunization clinics. The prevalence of SCD among the infant cohort was 0.8%. The infants diagnosed with SCD were immediately enrolled in the paediatric SCD clinic for disease-specific care. The HemoTypeSC test had 100% sensitivity and specificity for sickle cell disease in early infancy compared to HPLC. This study affirms that it is feasible and acceptable for mothers to implement a SCD screening intervention program in early infancy in Lagos State. The study also demonstrates the utility of the HemotypeSC rapid testing for ease and reduced cost of screening infants for SCD.

Abstract
Poor access to HIV viral load (VL) testing prevents the timely monitoring of HIV treatment adherence and efficacy. Factors enabling clinical benefits of VL testing when added to local standards of care, can inform the development of more cost-effective routine VL scale-up plans. We compared antiretroviral therapy (ART) switch practices in 13 clinics across 6 countries, with full (N = 8), phasing-in (N = 3) or no onsite access (N = 2) to VL. The analysis used data from the Pan-African Studies to Evaluate Resistance (PASER), observing virological and drug resistance outcomes among adults receiving first- or second-line ART between 2008 and 2015. Study plasma viral load (sVL) determined at baseline, every 12 months thereafter and at the time of switch served for retrospectively validating switch decisions, categorized into "necessary," "unnecessary," and "missed." Virological failure was defined as two consecutive sVL ≥1,000 HIV-RNA copies/mL. One thousand nine hundred ninety-five of the 2,420 (82.4%) study participants had continuous virological suppression during the median 30 months of follow-up. Among the 266 virological failures (11.0%), the proportion of necessary switches were similar in clinics with full (37%), phasing-in (25%), or no access (39%) to local VL testing. Documented utilization of local VL results for the switch decision was associated with higher percentage of necessary switch (87.6% vs. 67.9%). Shorter time to necessary switch was associated with higher rates of long-term virological suppression, regardless of access to local viral load. Availability of HIV VL testing capacity does not systematically result in adequate switch practices or better virological outcomes. Systems supporting sufficient test demand execution, and actual utilization of results for patient management need strengthening.

Abstract
Hydroxyurea (HU) is a well-known Hb F-inducing agent with proven clinical and laboratory efficacy for patients with sickle cell disease. However, concerns about its long-term safety and toxicity have limited its prescription by physicians and acceptability by patients. Thus, this study aims to evaluate clinician's barriers to the use of HU in the management of patients with sickle cell disease in Nigeria. An online survey targeted physicians in pediatrics, hematology, medicine, family medicine and general medical practice managing sickle cell disease in Nigeria. The survey was in four sections: demographic, knowledge and experience with HU, and barriers to the use of HU. Ninety-one (73.0%) of 123 contacts completed the survey. Seventy-three percent and 74.0% of the respondents noted that HU reduced transfusion rates and improved overall quality of life (QOL) of patients, respectively. While the majority of the practitioners (55.6%) see between 10-50 patients per month, most (66.7%) write <5 prescriptions for HU per month. Lack of a national guideline for use of HU, especially in children (52.0%), concern for infertility (52.0%), and safety profile of HU in pregnancy and lactation (48.2%), top the factors considered by the respondents as major barriers to the use of HU. Hydroxyurea is grossly under prescribed in Nigeria, despite that the vast majority of physicians who attend patients with sickle cell disease know about its clinical efficacy. Evidence-based clinical practice guidelines could be explored as a way to standardize practices and improve confidence of practitioners to improve physicians' prescription of HU in the management of sickle cell disease.

Abstract
Introduction: Sickle cell disease (SCD) is an inherited blood disorder characterized by clinical heterogeneity that may be influenced by environmental factors, ethnicity, race, social and economic factors as well as genetic and epigenetic factors. Areas covered: The present review was carried out to provide a comprehensive assessment of the current burden of SCD and treatments available for persons with SCD in Nigeria with the aim of identifying surveillance and treatment gaps, informing to guide the planning and implementation of better crisis prevention measures for SCD patients and set an agenda for new areas of SCD research in the country. This review assessed medical, biomedical and genetic studies on SCD patients in Nigeria and other endemic countries of the world. Expert opinion: Integration of hydroxyurea therapy into the management of SCD and surveillance via new-born screening (NBS) for early detection and management will improve the survival of persons with SCD in Nigeria. However, it will be important to carry out pilot studies, initiate strategic advocacy initiatives to educate the people about NBS benefits, develop collaborations between potential stakeholders and design sustainable financing scheme.

Abstract
This study evaluated the effects of aerobic exercise program on the cardiovascular parameters, body composition, and quality of life (QoL) of people living with human immune virus (HIV). Patients were recruited from the HIV clinic in a tertiary hospital in Nigeria. Fish bowl method was used to randomize the patients to either experimental or control group. Experimental group received nutritional counseling and aerobic exercise program on a treadmill, 3 times a week for a period of 6 weeks, while the control group received only nutritional counseling. Cardiovascular parameters, aerobic fitness, body composition parameters, and QoL were evaluated at baseline and 6 weeks. Descriptive statistics was used to explore demographic data while the hypothesis was tested using inferential statistics of t-test. Alpha level was set at P<0.05. The result showed that there was an improvement in cardiovascular parameters in both groups, attaining significance in the experimental group (P=0.000). Aerobic fitness increased significantly in experimental group (P=0.000). Body composition decreased significantly while there was a significant difference in the muscle mass (%) between groups (P<0.05). All domains of QoL had a significant improvement in both groups (P<0.005). A 6-week aerobic exercise program in addition to nutritional counseling was able to significantly improve cardiovascular fitness, body composition, and QoL in people living with HIV/acquired immune deficiency syndrome. Nutritional counseling alone can bring about an improvement only in QoL parameters.

Abstract
Genetic variants at three quantitative trait loci (QTL) for fetal haemoglobin (HbF), BCL11A, HBS1L-MYB and the β-globin gene cluster, have attracted interest as potential targets of therapeutic strategies for HbF reactivation in sickle cell anaemia (SCA). We carried out the first systematic evaluation of critical single nucleotide polymorphisms at these disease modifier loci in Nigerian patients with SCA. Common variants for BCL11A and HBS1L-MYB were strongly associated with HbF levels. At both loci, secondary association signals were detected, illustrating the mapping resolution attainable in this population. For BCL11A, the two independent sites of association were represented by rs1427407 (primary site, p = 7.0 x 10(-10)) and rs6545816 (secondary site, conditioned on rs1427407: p = 0.02) and for HBS1L-MYB by rs9402686 (HMIP-2B, p = 1.23 x 10(-4)) and rs66650371 (HMIP-2A, p = 0.002). Haplotype analysis revealed similarities in the genetic architecture of BCL11A and HBS1L-MYB in Nigerian patients. Variants at both loci also alleviated anaemia. The variant allele for the γ globin gene promoter polymorphism XmnI-HBG2 was too infrequent in our patients to be evaluated in this relatively small study. Studying the large and diverse SCA patient populations in African countries such as Nigeria will be key for a clearer understanding of how these loci work and for the discovery of new disease modifier genes.

Abstract
Antigens belonging to the Rh and Kell blood group systems are of major clinical significance because of their immunogenicity and the potential of their consequent antibodies to cause in vivo destruction of exogenous red blood cells (RBCs). Despite the wide-spread use of transfusion, there are sparse data on the prevalence of Rh and Kell system antigens and their ethnic variability in Nigeria. The objective of this study was to determine the prevalence of the five major Rh (D, C, c, E, e) and Kell (K) system antigens in Nigeria with the goal of understanding alloimmunization risk in transfusion recipients and improving transfusion safety through the availability of resources, such as antisera for extended RBC typing and antigen panels for alloantibody detection. A multi-ethnic cohort of 302 healthy Nigerian individuals was created to study RBC antigen prevalence. The antigen status of these individuals for Rh and K antigens was determined using commercially prepared antisera and conventional tube agglutination methods. The prevalence of the Rh antigens in the study cohort was found to be: D (92.7%), C (20.5%), c (97.7%), E (19.5%), and e (97.4%). Dce was the most common Rh phenotype (53.3%). The prevalence of K was 0 percent. For all antigens, there was no association between ethnicity and antigen prevalence. This study is the first to document the prevalence of the major Rh and K antigens in the Nigerian population, using a multi-ethnic cohort. Serologic testing demonstrates a zero prevalence of K antigen, which has never been described. C and E pose the higher risks of alloimmunization, hence showing a need for extended RBC typing and matching in at-risk blood recipients. This study demonstrates that phenotyping for major Rh and K antigens within the Nigerian population can potentially improve transfusion safety and prevent alloimmunization.

Abstract
BACKGROUND Preeclampsia (PE) is the second most common cause of maternal death after obstetric hemorrhage in Africa, a resource-limited region. This study was designed to examine the potential usefulness of a single screening plasma plasminogen activator inhibitor-1 (PAI-1) and fibronectin (FN) level for the prediction of PE in pregnant women. MATERIALS AND METHODS In a cohort of 180 pregnant women who were normotensive at baseline, venous blood samples were obtained before 20 weeks of gestation for the assay of plasma levels of PAI-1 and FN levels measured by enzyme-linked immunoassay technique. Twenty nonpregnant normotensive women were also evaluated as a control group. Outcomes of gestation were evaluated and correlated with the plasma levels of PAI and FN measured at mid-trimester. Mean plasma values of PAI-1 and FN were also compared between the different outcome groups. RESULTS Plasma PAI-1 level was significantly higher in the pregnant women (8.68 ± 0.56 ng/ml) than in nonpregnant controls (5.55 ± 0.32 ng/ml) (P = 0.01). However, plasma FN did not show any significant difference in pregnant women (2.60 ± 0.37 μg/ml) and nonpregnant controls (2.60 ± 0.23 μg/ml) (P = 0.9). Mid-trimester mean plasma PAI-1 level measured in women who developed PE (7.08 ± 5.49 ng/ml, n = 12) and gestational hypertension (GH) (9.78 ± 6.2 ng/ml, n = 13) was not significantly different in comparison to normotensive pregnant women (8.78 ± 5.63 ng/ml, n = 153) (P = 0.75). Likewise, the mean FN level in women who developed PE was also not significantly different from nonpreeclamptics; however, the FN level in the pregnant women who developed GH was significantly different from women who remained normotensive throughout pregnancy (P = 0.02). CONCLUSION Single mid-trimester assessment of PAI-1 and FN levels in maternal plasma was not found to be useful in predicting PE as an outcome of pregnancy in the study population.

Abstract
BACKGROUND As antiretroviral therapy (ART) programs in sub-Saharan Africa mature, increasing numbers of persons with human immunodeficiency virus (HIV) infection will experience treatment failure, and require second- or third-line ART. Data on second-line failure and development of protease inhibitor (PI) resistance in sub-Saharan Africa are scarce. METHODS HIV-1-infected adults were included if they received >180 days of PI-based second-line ART. We assessed risk factors for having a detectable viral load (VL, ≥400 cps/mL) using Cox models. If VL was ≥1000 cps/mL, genotyping was performed. RESULTS Of 227 included participants, 14.6%, 15.2% and 11.1% had VLs ≥400 cps/mL at 12, 24, and 36 months, respectively. Risk factors for a detectable VL were as follows: exposure to nonstandard nonnucleoside reverse-transcriptase inhibitor (NNRTI)-based (hazard ratio, 7.10; 95% confidence interval, 3.40-14.83; P < .001) or PI-based (7.59; 3.02-19.07; P = .001) first-line regimen compared with zidovudine/lamivudine/NNRTI, PI resistance at switch (6.69; 2.49-17.98; P < .001), and suboptimal adherence (3.05; 1.71-5.42; P = .025). Among participants with VLs ≥1000 cps/mL, 22 of 32 (69%) harbored drug resistance mutation(s), and 7 of 32 (22%) harbored PI resistance. CONCLUSIONS Although VL suppression rates were high, PI resistance was detected in 22% of participants with VLs ≥1000 cps/mL. To ensure long-term ART success, intensified support for adherence, VL and drug resistance testing, and third-line drugs will be necessary.

Abstract
OBJECTIVE Prescribing, adherence, and adverse drug events to HAART in a large antiretroviral programme in Lagos was evaluated. DESIGN A retrospective 5 year open cohort study. SETTING The AIDS Prevention Initiative in Nigeria (APIN) clinic at LUTH is one of the United States Presidential Emergency Plan for AIDS Relief (PEP-FAR) funded centers for HIV relief program in Nigeria Participants The case files of 390 patients on HAART and attending the APIN clinic were reviewed sequel to random selection. MAIN OUTCOME MEASURES Demographics of the patients and pattern of antiretroviral (ARV) combination drugs prescribed were extracted from their case files. The details of the adverse drug events (ADEs) were extracted from drug toxicity forms regularly filled for each patient. A Chi-square test with Yates correction was used to determine the association between adherence and therapeutic outcome. RESULTS A total of 2944 prescriptions were assessed. Zidovudine + lamivudine + nevirapine (35.87%) and stavudine + lamivudine + nevirapine (35.63%) were the most frequently prescribed combinations. Over 2000 ADEs were reported with cough (13.3%), fever (8.75%) and skin rashes (8.01%) being the most frequently reported. Drug adherence was associated with good therapeutic outcome (χ(2) = 115.60, p<0.0001). CONCLUSIONS Zidovudine + lamivudine + nevirapine was the most frequently prescribed ARV combination. Cough was the most frequently reported ADE. Interventions aimed at rational prescribing of ARV drugs and improving adherence to antiretroviral drugs is essential for good therapeutic outcome in the treatment of HIV infection.

Abstract
BACKGROUND Group O donor blood is more readily available and is frequently used as universal red cell donor in our environment. The presence of hemolysins in the donors may however lead to hemolysis in the recipients. Attempts have been made to study the prevalence of hemolysins in various populations with results from our environment showing wide variation (20-80%). AIMS To determine the prevalence and titer of anti-A and anti B hemolysins among blood donors at the Lagos University Teaching Hospital and compare results with that obtained elsewhere. Determine if the practice of transfusion of group O blood to nongroup O recipients is permissible in this environment. MATERIALS AND METHODS Test for hemolysis was done using the standard tube method. Samples positive for hemolysis were then scored and titrated with the titers read visually and photometrically at 540 nm. RESULTS Three hundred and fifty blood group O donors with age range 18-58 years and median age of 28 8.4 years were enrolled in the study. The overall prevalence of anti-A and/or anti-B hemolysins obtained was 30.3%. Prevalence of anti-A and anti-B hemolysins only was 15.4% and 5.1% respectively whereas both anti-A and anti-B hemolysins were present in 9.7% donor samples. Though anti-A hemolysins were more prevalent than anti-B hemolysins, anti-B hemolysins had higher mean visual (6:7) and spectrophotometric titers (81:101). A visual titer of 8 and above which is considered significant was seen in 18.6% of donor samples. CONCLUSION Anti-A and anti-B hemolysins exist in significant frequencies and titers among blood group O donors in Lagos. It is recommended that the use of group O donor blood for recipients who are non-O be discouraged. Clinical studies to determine the frequency and severity of hemolysis in non-group O recipients of blood group O are required.

Abstract
BACKGROUND After the scale-up of antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection in Africa, increasing numbers of patients have pretreatment drug resistance. METHODS In a large multicountry cohort of patients starting standard first-line ART in six African countries, pol genotyping was retrospectively performed if viral load (VL) ≥1000 cps/mL. Pretreatment drug resistance was defined as a decreased susceptibility to ≥1 prescribed drug. We assessed the effect of pretreatment drug resistance on all-cause mortality, new AIDS events and switch to second-line ART due to presumed treatment failure, using Cox models. RESULTS Among 2579 participants for whom a pretreatment genotype was available, 5.5% had pretreatment drug resistance. Pretreatment drug resistance was associated with an increased risk of regimen switch (adjusted hazard ratio [aHR] 3.80; 95% confidence interval [CI], 1.49-9.68; P = .005) but was not associated with mortality (aHR 0.75, 95% CI, .24-2.35; P = .617) or new AIDS events (aHR 1.06, 95% CI, .68-1.64; P = .807). During three years of follow up, 106 (4.1%) participants switched to second-line, of whom 18 (17.0%) switched with VL < 1000 cps/mL, 7 (6.6%) with VL ≥ 1000 cps/mL and no drug resistance mutations (DRMs), 46 (43.4%) with VL ≥ 1000 cps/mL and ≥1 DRMs; no HIV RNA data was available for 32 (30.2%) participants. CONCLUSIONS Given rising pretreatment HIV drug resistance levels in sub-Saharan Africa, these findings underscore the need for expanded access to second-line ART. VL monitoring can improve the accuracy of failure detection and efficiency of switching practices.

Abstract
BACKGROUND Sickle cell disease impacts the physical, emotional and psychological aspects of life of the affected persons, often times exposing them to disease associated stigma from the society and alters the health related quality of life (HRQoL). This study compared the HRQoL of adolescents with sickle cell disease with their healthy peers, identified socio-demographic and clinical factors impacting HRQoL, and determined the extent and effects of SCD related stigma on quality of life. PROCEDURE We conducted a cross-sectional survey among 160 adolescents, 80 with SCD and 80 adolescents without SCD. Socio-demographic and clinical data were collected using a pre-tested questionnaire. HRQoL was investigated using the Short Form (SF-36v2) Health Survey. SCD perceived stigma was measured using an adaptation of a perceived stigma questionnaire. RESULTS Adolescents with SCD have significantly worse HRQoL than their peers in all of the most important dimensions of HRQoL (physical functioning, physical roles limitation, emotional roles limitation, social functioning, bodily pain, vitality and general health perception) except mental health. Recent hospital admission and SCD related complication further lowered HRQoL scores. Over seventy percent of adolescents with SCD have moderate to high level of perception of stigmatisation. Hospitalisation, SCD complication, SCD stigma were inversely, and significantly associated with HRQoL. CONCLUSIONS Adolescents living with SCD in Nigeria have lower health related quality of life compared to their healthy peers. They also experience stigma that impacts their HRQoL. Complications of SCD and hospital admissions contribute significantly to this impairment.

Abstract
Background Multi-therapy is common in HIV-infected children, and the risk for clinically significant drug interactions (CSDIs) is high. We investigated the prevalence of CSDIs between antiretroviral (ARV) and co-prescribed drugs for children attending a large HIV clinic in Lagos, Nigeria. Methods The case files of pediatric patients receiving treatment at the HIV clinic of the Lagos University Teaching Hospital (LUTH), Idi-Araba, between January 2005 and December 2010 were reviewed. The ARV and co-prescribed drug pairs were evaluated for potential interactions using the Liverpool HIV Pharmacology Group website. The potential interactions were rated as A (no known interaction), B (minor/no action needed), C (moderate/monitor therapy), D (major/therapy modification), and X (contraindicated/avoid combination). Results Of the 310 cases reviewed, 208 (67.1%) patients were at risk of CSDIs. Artemisinin-based combination therapy was prescribed for over one-half of the patients, accounting for 40% of the CSDIs. Excluding this drug class, the prevalence of CSDIs reduced from 67.1% to 18.7% in 58 patients. Most of the CSDIs (579; 97.2%) were moderately significant and frequently involved nevirapine and fluconazole (58; 9.7%), zidovudine and fluconazole (55; 9.2%), zidovudine and rifampicin (35; 5.9%), and nevirapine and prednisolone (31; 5.2%). Age (P=0.392), sex (P=0.783), and moderate (P=0.632) or severe (P=0.755) malnutrition were not associated with risk for CSDIs. Conclusion There is a tendency for CSDIs between ARV and co-prescribed drugs among the group of children evaluated in this study. Measures are necessary to prevent important drug interactions and to manage those that are unavoidable.

Abstract
Background Apart from challenging the bone marrow to increase its red cell production, thereby producing more blood for the donor, regular blood donation has been shown to have several benefits, one of which is preventing accumulation of body iron which can cause free radical formation in the body. This study was carried out to assess body iron stores in regular blood donors. Methods A total of 52 regular (study) and 30 first-time (control) volunteer blood donors were studied prospectively. Twenty milliliters of venous blood was drawn from each subject, 5 mL of which was put into sodium ethylenediamine tetra-acetic acid specimen bottles for a full blood count, including red blood cell indices. The remaining sample was allowed to clot in a plain container, and the serum was then retrieved for serum ferritin, serum iron, and serum transferrin receptor measurement by enzyme-linked immunosorbent assay. Results Mean hemoglobin and packed cell volume in the study group (13.47 ± 2.36 g/dL and 42.00 ± 7.10, respectively, P = 0.303) were not significantly higher than in the control group (12.98 ± 1.30 g/dL and 39.76 ± 4.41, respectively, P = 0.119). Mean serum ferritin was 102.46 ± 80.26 ng/mL in the control group and 41.46 ± 40.33 ng/mL in the study group (P = 0.001). Mean serum ferritin for women in the study group (28.02 ± 25.00 ng/mL) was significantly lower than for women in the control group (56.35 ± 34.03 ng/mL, P = 0.014). Similarly, men in the study group had a lower mean serum ferritin (48.57 ± 45.17 ng/mL) than men in the control group (145.49 ± 87.74 ng/mL, P = 0.00). The mean serum transferrin receptor value was higher in the study group (1.56 ± 0.88 μg/mL) than in the control group (1.19 ± 0.38 μg/mL, P = 0.033). Conclusion These findings suggest that hemoglobin concentration, packed cell volume, and serum iron levels are not significantly affected by regular blood donation and that regular blood donors appear to have reduced iron stores compared with controls.

Abstract
BACKGROUND Pre-delivery haemoglobin and serum ferritin concentrations of anaemic and non-anaemic mothers were determined, and cord blood haemoglobin and serum ferritin concentrations of their newborns were compared. This is to establish the mean values for pre-delivery haemoglobin and serum ferritin concentrations of anaemic and non-anaemic mothers and the cord blood haemoglobin and serum ferritin concentrations of their newborns at term. MATERIALS AND METHODS A case-control study was done involving 142 pregnant women and their newborns. They were divided into two groups - the anaemic group (n = 65) and the non-anaemic (n = 77) group. Five millilitres of blood was collected from each woman and 2 ml was collected from the cord of their newborns into ethylenediaminetetraacetic acid (EDTA) bottle and plain bottle for full blood count analysis and ferritin assay, respectively. RESULTS The mean pre-delivery haemoglobin concentrations of the women in anaemic group and non-anaemic group were 9.5 ± 1.01 g/dl and 12.15 ± 1.07 g/dl, respectively, and their mean serum ferritin concentrations were 64.45 ± 138.76 μg/l and 32.83 ± 35.36 μg/l, respectively. The mean cord blood haemoglobin concentrations for anaemic and for non-anaemic groups were 12.54 ± 2.54 g/dl and 13.44 ± 2.23 g/dl (P = 0.02), respectively, and the mean cord blood serum ferritin concentrations (non-anaemic, 69.38 ± 78.88 μg/l; anaemic, 7.26 ± 115.60 μg/l) (P = 0.00) were higher in the newborns of non-anaemic than of anaemic mothers. Significant association was found between maternal anaemia and cord blood ferritin concentrations (P = 0.025). CONCLUSION Maternal anaemia has significant effects on cord blood haemoglobin and serum ferritin concentrations.

Abstract
OBJECTIVES Hereditary resistance to activated Protein C (Factor V Leiden) is the commonest genetic defect known to confer a predisposition to thrombosis. This study aims to determine the prevalence of activated protein C resistance (APCr) in Lagos, and to determine if any association exists between APCr and ABO, Rhesus blood types, and hemoglobin phenotypes. MATERIALS AND METHODS A functional APCr test was conducted on healthy adult volunteers to get a Factor-V-related activated protein C ratio (APC-V ratio). APCr due to Factor V mutation was indicated when the APC-V ratio is below a cut-off value that was determined by calibration. Subjects' hemoglobin, red cell ABO, and Rhesus phenotypes were determined by standard methods. RESULTS Six (2%) of 297 participants with normal baseline coagulation screening tests had functional resistance to activated protein C (APC-V ratio < 2). None of the six subjects with APCr had history of venous thromboembolism. One of the six subjects was a female but the male sex did not demonstrate a risk of inheritance of APCr (P = 0.39). Four (67%) of the six subjects with APCr were non-O blood group. Whereas only two (0.9%) of 226 non-A subjects (blood groups 0 and B) had APCr, 4 (6%) of 71 subjects with A gene (blood groups A and AB) had APCr. The inheritance of A gene appears to constitute a risk to inheritance of APCr (P = 0.03). No association was demonstrable between APCr and hemoglobin phenotypes. CONCLUSION Only 2% of the studied population had resistance to APC. The inheritance of blood group A may be a predisposition to APCr.

Abstract
The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases with special reference to hemato-oncologic, immuno-deficiency disorders, and human immunodeficiency virus infection. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases with emphasis on hemato-oncologic and human immunodeficiency virus (HIV) infection. Mesh phrases used in the search were: Oral diseases AND hematological disorders; orofacial diseases AND leukemias; orofacial lesions AND lymphomas; orofacial diseases AND multiple myeloma, orofacial manifestations AND HIV. The Boolean operator "AND" was used to combine and narrow the searches. The full texts of these articles were thoroughly examined. References in these articles also were manually searched non-Medline articles. Only relevant articles were selected for the review. Orofacial manifestation of malignant hematological diseases may present as primary clinical features due to infiltration of orofacial tissues, or as secondary due to the subsequent infiltration of normal bone marrow elements, or tertiary due to the side effects of the treatment. HIV-associated orofacial lesion may be a clinical indicator of HIV infection in otherwise healthy, undiagnosed individuals; an early clinical feature of HIV infection; clinical markers for the classification and staging of HIV disease or may be a predictor of HIV disease progression. Orofacial manifestations of malignant hematological diseases and HIV infection are not uncommon findings in clinical practice. These manifestations may be clinical indicators of hematologic disorders in otherwise healthy, undiagnosed individuals.

Abstract
Background The prevalence of monoclonal gammopathy of undetermined significance (MGUS), a premalignant plasma-cell disorder has not been determined in our geographic area Nigeria. Methods A cross sectional survey was carried on apparently healthy Nigerians selected by multistage sampling technique from the cosmopolitan city of Lagos, Nigeria. Subjects enrolled into the study had 2-step screening for the presence, type and concentration of monoclonal band. Agarose-gel electrophoresis was performed on all serum samples, and any serum sample with a discrete band of monoclonal protein or thought to have a localized band was subjected to Immunofixation. Subjects were also evaluated for Bence jones proteinuria, haematological and biochemical parameters. Results Four hundred and ten subjects with a mean age of 45.68 ± 10.3 years, a median of 45.00 years and a range of 20 to 80 years were enrolled into the study. MGUS was identified in only one (0.24 percent) of the 410 study subject. This subject was demonstrated to have a double monoclonal gammopathy; IgGλ at 16.9 g/L and IgAκ at 8.5 g/L. None of them including the sole subject with MGUS had a monoclonal urinary light chain. Conclusion Among residents of Lagos, Nigeria, MGUS was found in only 0.24% percent of apparently normal persons with a median age of 45 years. This suggests that MGUS which represents the earliest stage of monoclonal plasma/lymphoid cell proliferation is not a common finding in the relatively young population of Nigeria. Future epidemiologic studies dealing with plasma cell disorders in older people are required to carefully examine the relationship between environmental factors and prevalence of MGUS and its ultimate progression to MM.

Abstract
The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases, with particular reference to anemias and disorders of hemostasis. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases, with emphasis on anemia. Mesh phrases used in the search were: oral diseases AND anaemia; orofacial diseases AND anaemia; orofacial lesions AND anaemia; orofacial manifestations AND disorders of haemostasis. The Boolean operator "AND" was used to combine and narrow the searches. Anemic disorders associated with orofacial signs and symptoms include iron deficiency anemia, Plummer-Vinson syndrome, megaloblastic anemia, sickle cell anemia, thalassaemia and aplastic anemia. The manifestations include conjunctiva and facial pallor, atrophic glossitis, angular stomatitis, dysphagia, magenta tongue, midfacial overgrowth, osteoclerosis, osteomyelitis and paraesthesia/anesthesia of the mental nerve. Orofacial petechiae, conjunctivae hemorrhage, nose-bleeding, spontaneous and post-traumatic gingival hemorrhage and prolonged post-extraction bleeding are common orofacial manifestations of inherited hemostatic disorders such as von Willebrand's disease and hemophilia. A wide array of anemic and hemostatic disorders encountered in internal medicine has manifestations in the oral cavity and the facial region. Most of these manifestations are non-specific, but should alert the hematologist and the dental surgeon to the possibilities of a concurrent disease of hemopoiesis or hemostasis or a latent one that may subsequently manifest itself.

Abstract
Background Hepatitis B virus (HBV) is a common cause of liver disease throughout the world. HBV is transmitted through blood and other body fluids, including semen and saliva. Chronic replication of HBV virons is characterized by persistence circulation of HBsAg, HBeAg and HBV DNA; usually with anti-HBc and occasionally with anti-HBs. Aim: To determine the prevalence of HBeAg, IgG anti-HBcore and IgM anti-HBcore amongst HBsAg positive blood donors. These parameters are reflective of transmissibility and active hepatitis B infection. A cross sectional study was carried out at the blood donor clinics of Lagos State University Teaching Hospital Ikeja and Lagos University Teaching Hospital Idiaraba. A total of 267 donors were recruited to determine HBe antigen, IgG and IgM anti-HBcore antibodies amongst hepatitis BsAg positive donors. Five milliliters of blood was collected from those who tested positive to HBsAg screen during donation. The sera were subjected to enzyme linked immunosorbent assay (ELISA). Pearson chi-squared test was used for the analytical assessment. Findings A total number of 267 HBsAg positive blood donors were studied. A seroprevalence of 8.2% (22 of 267) HBeAg was obtained, 4 of 267 (1.5%) were indeterminate while 241 (90.3%) tested negative. Only 27 out of 267 donors (10.1%) tested positive to IgM anti-HBcore, 234(87.6%) tested negative, while 6(2.2%) were indeterminate. A higher percentage of 60.7% (162 of 267) tested positive to IgG anti-HBcore, while 39.3% (105 of 267) tested negative. Conclusion There is a low seroprevalence rate of HBeAg-positive chronic hepatitis and relatively high IgG anti-HBcore and IgM anti-HBcore rates in South West Nigeria.

Abstract
INTRODUCTION Among opportunistic pathogens associated with acquired immunodeficiency syndrome (AIDS), Mycobacterium tuberculosis is distinguished by its relative virulence and potential for person-to-person transmission. Oxidative stress is associated with TB infection with a high level in patients with HIV-TB co-infection. However, the comparative level of oxidative stress in HIV patients on highly active anti-retroviral therapy (HAART) and naïve (untreated) HIV patients is not clear. METHODOLOGY This study is aimed to determine the level of oxidative stress and haematological parameters in HIV patients (naïve), HIV patients undergoing HAART, and HIV-TB co-infected patients. In total, 100 consenting subjects were recruited from the AIDS Prevention Iniative in Nigeria (APIN) Clinic. For controls, normal male healthy volunteers were recruited from the blood donor clinic and females from the APIN clinic staff members, both of the Lagos University Teaching Hospital. Measurements of antioxidant enzyme activity and lipid peroxidation were performed according to standard procedures. Haematological parameters were determined using a fully automated hematology analyzer. RESULTS Red blood cells significantly decreased (P ≤ 0.001) in all patients when compared with control subjects. The lipid peroxidation (MDA) was significantly high (P ≤ 0.05) in naive patients when compared to HIV patients on HAART. The decrease in the levels of GSH in both naive and HIV-TB co-infected patients (P ≤ 0.001) and HIV patients on HAART (P < 0.05) were significant when compared to control patients. CONCLUSION There is lower antioxidant level and higher MDA in naive and HIV-TB co-infected patients as compared to HIV patients on HAART and the seronegative patients.

Abstract
BACKGROUND Anaemia in pregnancy is defined as haemoglobin (Hb) concentrations of less than 11 g/dL while low ferritin is defined as serum ferritin (SR) levels of less than 10 µg/L. Hb and ferritin concentrations of pregnant women at term were determined to establish their mean values and to determine the prevalence of anaemia in our locality. METHODS Haemoglobin and ferritin levels of 170 non-smoking and HIV-negative pregnant women were determined at term. The majority 143 of 170 (84.1%) of the pregnant women recruited for the study, booked at the beginning of the second trimester and received 200 mg elemental iron in three divided doses and 5 mg folic acid daily which were commenced at booking. Five millilitres of blood were collected from each patient at term into EDTA bottles for full blood count analysis and another 5 mL into plain bottles for SR assay. RESULTS The mean Hb and ferritin values were 10.9 ± 1.9 and 47.84 ± 98.39 µg/L, respectively. The prevalence of anaemia at term was 46.4%. Only 11.2% (19 of 170) of pregnant women at term had low SR (iron stores). A statistically significant relationship was found between women's education and SR (P = 0.032). Booking status also correlated directly with SR and haemoglobin concentrations, while increasing age and parity did not. CONCLUSION About half of the patients were anaemic. Iron deficiency is not the major cause of anaemia in pregnancy in this study because the majority of the pregnant women had normal iron stores. Education and booking status are possible factors that contribute to anaemia.

Abstract
BACKGROUND Haemoglobin(Hb) and serum ferritin (SF) concentrations of cord blood of babies born at term at the Lagos State University Teaching Hospital, Maternity Centre (Ayinke House), Ikeja in the South-Western part of Nigeria were determined to establish mean values for these substances in our locality. OBJECTIVES To establish the mean values for haemoglobin and serum ferritin concentrations of cord blood of babies born at term in our environment and to determine the prevalence of foetal anaemia and low iron store in cord blood in our locality. METHODS Haemoglobin and ferritin levels in cord blood of 142 newborns were determined. Two millilitres of blood was collected from the cord of each newborn into EDTA bottle for complete blood count analysis and another 2mls into a plain bottle for serum ferritin assay. Cut-off values for cord blood Hb and serum ferritin concentrations were 12.5g/dL and 60 microg/L respectively. RESULTS The mean Hb and ferritin values were 13.024 +/- 2.41 g/dL and 70.85 +/- 97.07 microg/dL respectively. The prevalence of foetal anaemia is 32.4 %. About 59.2% of full term newborns had low iron store. Birth weight was significantly associated with Hb concentration (p=0.039) and apga sscore (p=0.002). CONCLUSION The prevalence of foetal anaemia was 32.4%. More than half (59.2%) of the newborns had low cord blood serum ferritin.

Abstract
AIMS AND OBJECTIVES The study aimed at reviewing the utilisation of blood / blood products and haematological profile changes, with a view to developing a hospital transfusion guideline in open heart surgery in Nigeria. MATERIALS AND METHODS The surgeries were performed at the intensive care unit theatre of Lagos State University Teaching Hospital. Eligibility for surgery was determined by the Cardiologist and the cardiovascular Surgeon based on clinical presentation, electro- and echocardiography assessments among other tests. Fourteen open-heart surgeries were conducted. Blood products demand for different procedures and several peri-operative laboratory parameters such as full blood count, and coagulation profile were determined. RESULTS The greatest demand for blood products was found in valvular surgery and atrial septal defect (ASD) where a mean of four units of red cell concentrate, fresh frozen plasma and cryoprecipitate were transfused. Other surgeries such as, patent ductus arteriosus, Tetralogy of Fallot did not require much transfusion of blood products. Overall, the pre-operative and post-operative haematocrit, white cell count, platelet count, and international normalized ratio (INR) mean were 37% /25%,4.9 X 10 9/L / 11.4 X 10 9/L, 182 X 10 9/L/ 97 X 10 9/L, and 1.15/ 2.2 respectively. CONCLUSION It appears that transfusion requirement in most open heart surgeries aside from valvular surgery and atrial septal defect (ASD) repair, is minimal. Patients for valvular heart surgeries and ASD repair should be evaluated for possible autologous blood transfusion.

Abstract
BACKGROUND Infertility is a major problem in sickle cell disease patients, especially in males. In addition to low serum testosterone, other abnormalities involving the accessory sex organs, such as the seminal vesicles and the prostate gland, as well as marked decrease in ejaculate volume may be observed in male HbSS patients. Hence, the need to study the role of sex hormones as a cause of infertility in male HbSS patients. METHODS An unmatched case-control study was performed using seventy-five consenting subjects from Lagos University Teaching Hospital. These included 47 patients with haemoglobin phenotype SS from the Sickle cell clinic and 28 volunteered medical students and members of staff with haemoglobin phenotype AA. Demographic data were obtained using a self-administered questionnaire. A total of 5 mls of blood was collected from each subject between 9.00 am & 11.am, and assayed for serum testosterone concentration. RESULTS The concentrations of serum testosterone in HbSS patients ranged from 0.2 to 4.3 ng/ml with a mean of 1.28 ± 0.72 ng/ml whilst the values in HbAA controls ranged from 1.2 to 6.9 ng/ml with a mean of 2.63 ± 1.04 ng/ml. Seven (25.0%) of the 28 controls had serum testosterone concentration lower than the quoted reference (normal) range whereas 44 (93.6%) of the 47 HbSS subjects had serum testosterone concentration lower than the reference range. CONCLUSION Overall, subjects with HbSS have significantly lower mean serum testosterone than HbAA controls.

Abstract
Aim: The study aims to determine the frequency of homologous blood transfusion in patientsundergoing cleft lip and palate surgery at the Lagos University Teaching Hospital, Nigeria. Setting and Design: A prospective study of transfusion rate in cleft surgery conducted at the Lagos University Teaching Hospital, Nigeria. Material and Methods: One hundred consecutive patients who required cleft lip and palate surgery were recruited into the study. Data collected included age, sex and weight of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Each patient was made to donate a unit of homologous blood prior to surgery. Results: There were 52 females and 48 males with a mean age of 64.4 ± 101.1 months (range, 3-420 months). The most common cleft defect was isolated cleft palate (45%) followed by unilateral cleft lip (28%). Cleft palate repair was the most common procedure (45%) followed by unilateral cleft lip repair (41%). The mean estimated blood loss was 95.8 ± 144.9 ml (range, 2-800ml). Ten (10%) patients (CL=2; CP=5, BCL=1; CLP=2) were transfused but only two of these were deemed appropriate based on percentage blood volume loss. The mean blood transfused was 131.5 ± 135.4ml (range, 35-500ml). Six (60%) of those transfused had a preoperative PCV of < 30%. Only 4.9% of patients who had unilateral cleft lip surgery were transfused as compared with 50% for CLP surgery, 11% for CP surgery, and 10% for bilateral cleft lip surgery. Conclusions: The frequency of blood transfusion in cleft lip and palate surgery was 10% with a cross-match: transfusion ratio of 10 and transfusion index of 0.1. A "type and screen" policy is advocated for cleft lip and palate surgery.

Abstract
OBJECTIVE Cleft lip surgery is a common procedure performed by surgeons worldwide. The aim of the study was to determine blood transfusion requirements and factors influencing blood transfusion in cleft lip surgery. METHODS Transfusion rate in 100 consecutive patients who had cleft lip surgery was prospectively evaluated at the Lagos University Teaching Hospital, Nigeria. Data collected included age and sex of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Cardiovascular parameters at the point of transfusion were also recorded. Each patient was made to donate a unit of homologous blood prior to surgery. RESULTS Mean estimated blood loss during surgery was 26.5 ± 47.1 ml. Most patients (92%) lost between 2 and 50 ml of blood. Mean estimated blood loss in unilateral cleft lip surgery was not significantly differently from that of bilateral cleft lip surgery (P=0.46). Only five patients (5%) required blood transfusion. The mean blood transfused was 50.0 ± 16.9 ml. All the patients transfused had a preoperative haematocrit of <30% (23-27%). The cross-match-to-transfusion ratio for cleft surgery was 20. The transfusion index was 0.05 and overall blood-ordering quotient was 20. CONCLUSION Cleft lip surgery is a low volume blood loss surgery. Homologous blood donation prior to cleft lip surgery in patients with preoperative haematocrit of 30% or more is not necessary. For patients with preoperative haematocrit of less than 30%, type and screen of donated blood should be adequate.

Abstract
BACKGROUND Hepatitis C virus (HCV) and HIV are transmitted via similar routes making co-infection with these viruses a common event. In addition, HIV infection and related immunosupression in patients with hepatitis C may be associated with more rapid progression of liver disease to cirrhosis, end-stage liver disease and death. OBJECTIVE The study is to determine the seroprevalence of HIV/HCV co-infection rate. METHODS A cross -sectional study was carried out from January to March 2010 at the HIV clinic of the Lagos State University Teaching Hospital. About 5 mls of blood sample was collected from each consenting participant. Sera were subjected to HCV rapid kit as recommended by the manufacturer (Dia Spot HCV one step test strip). The descriptive data was given as means +/- standard deviation (SD). The chi-squared test was used for analytical assessment. The differences were considered statistically significant when P value obtained was < 0.05. RESULTS The overall seroprevalence rate of HIV/HCV coinfection was 3.3%. Only 6 of 194 female HIV subjects screened tested positive for HCV (3.1%), while 3 of 73 male subjects tested positive for HCV (4.1%) (P value 0.001). None of the 9 co-infected HIV/HCV participants (both male and female) had CD4 count of 350 and above, 3 had a count of 1-100 cells/il., 4 had 100-200, while 2 had 201-350. CONCLUSION There is the need to include hepatitis C screening routinely in all HIV-infected patients undergoing pre-HAART evaluation in HIV clinics in order to lower liver-related morbidity and mortality associated with them.

Abstract
BACKGROUND Toxoplasma gondii (T.gondii), an obligate intracellular parasite found in many species throughout the world, causes a variety of clinical syndromes in humans and animals. It is also associated with morbidity and mortality in pregnancy. Hence the need to determine the seroprevalence of antibody to toxoplasmosis gondii amongst pregnant women. SUBJECTS AND METHODS A cross- sectional study was carried out using patients attending the ante-natal clinic of Lagos State University Teaching Hospital Ikeja. All consenting newly registered ante-natal patients were recruited consecutively into the study within a time frame of six weeks during which a total of 179 pregnant participants were recruited. Literate participants filled self administered questionnaires whilst the non-literate participants were interviewed by research assistants. Five milliliters of blood was collected from each participant after obtaining patient's consent. Sera were assayed for antitoxoplasmosis IgG antibody by enzyme linked immunosorbent assay. (ELISA.) RESULTS A total of 179 pregnant women were studied. Almost 50.8% were between the ages of 25-30 years, 70.8% of the patients studied, had tertiary education. An assessment of the patients' status to anti-toxoplasmosis IgG showed 40.8% were positive while 59.2% were negative. Pet-keeping was a practice amongst only 6.1% of patients whilst 90.5% did not keep pets. Out of those who kept pets, 63.6% were positive while 39.5% were negative. Amongst those who did not keep pets, 39.5% were positive while 60.5% were negative. This difference was not statistically significant. (P=0.261) CONCLUSION It appears that seroprevalence of toxoplasmosis IgG antibody amongst the pregnant women in this study population is high. Therefore, it is valuable to follow up the IgMantibody status of their off springs as its presence indicates recent exposure.

Abstract
ABSTRACT
Aim: The study aims to determine the frequency of homologous blood transfusion in patientsundergoing cleft lip and palate surgery at the Lagos University Teaching Hospital, Nigeria. Setting and Design: A prospective study of transfusion rate in cleft surgery conducted at the Lagos University Teaching Hospital, Nigeria. Material and Methods: One hundred consecutive patients who required cleft lip and palate surgery were recruited into the study. Data collected included age, sex and weight of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Each patient was made to donate a unit of homologous blood prior to surgery. Results: There were 52 females and 48 males with a mean age of 64.4 ± 101.1 months (range, 3-420 months). The most common cleft defect was isolated cleft palate (45%) followed by unilateral cleft lip (28%). Cleft palate repair was the most common procedure (45%) followed by unilateral cleft lip repair (41%). The mean estimated blood loss was 95.8 ± 144.9 ml (range, 2-800ml). Ten (10%) patients (CL=2; CP=5, BCL=1; CLP=2) were transfused but only two of these were deemed appropriate based on percentage blood volume loss. The mean blood transfused was 131.5 ± 135.4ml (range, 35-500ml). Six (60%) of those transfused had a preoperative PCV of < 30%. Only 4.9% of patients who had unilateral cleft lip surgery were transfused as compared with 50% for CLP surgery, 11% for CP surgery, and 10% for bilateral cleft lip surgery. Conclusions: The frequency of blood transfusion in cleft lip and palate surgery was 10% with a cross-match: transfusion ratio of 10 and transfusion index of 0.1. A “type and screen” policy is advocated for cleft lip and palate surgery.
