Abstract
BACKGROUND Lymphoma is a leading cause of cancer-related death among human immunodeficiency virus (HIV)-infected individuals in the current era of potent anti-retroviral therapy (ART). Globally, mortality after HIV-associated lymphoma has profound regional variation. Little is known about HIV-associated lymphoma mortality in Nigeria and other resource-limited setting in sub-Saharan Africa. Therefore, we evaluated the all-cause mortality after lymphoma and associated risk factors including HIV at the Jos University Teaching Hospital (JUTH) Nigeria. METHODS We conducted a ten-year retrospective cohort study of lymphoma patients managed in JUTH. The main outcome measured was all-cause mortality and HIV infection was the main exposure variable. Overall death rate was estimated using the total number of death events and cumulative follow up time from lymphoma diagnosis to death. Cox proportional hazard regression was used to assess factors associated with mortality after lymphoma diagnosis. RESULTS Out of 40 lymphoma patients evaluated, 8(20.0%) were HIV positive and 32(80.0%) were HIV negative. After 127.63 person- years of follow-up, there were 16 deaths leading to a crude mortality rate of 40.0 per 100 person-years. The 2-year probability of survival was 30% for HIV-infected patients and 74% for HIV-uninfected. Median survival probability for HIV-infected patients was 2.1 years and 7.6 years for those without HIV. Unadjusted hazard of death was associated with late stage, HR 11.33(95% CI 2.55, 50.26,p = 0.001); low cumulative cycles of chemotherapy, HR 6.43(95% CI 1.80, 22.89,p = 0.004); greater age, HR 5.12(95% CI 1.45,18.08,p = 0.01); presence of comorbidity, HR 3.43(95% CI 1.10,10.78,p = 0.03); and HIV-infection, HR 3.32(95% CI 1.05, 10.51,p = 0.04). In an adjusted model only stage was significantly associated with death, AHR 5.45(1.14-26.06, p = 0.03). CONCLUSION Our findings suggest that HIV- infection accounted for three times probability of death in lymphoma patients compared to their HIV-uninfected counterparts due to late stage of lymphoma presentation in this population. Also initiation of chemotherapy was associated with lower probability of death among lymphoma patients managed at JUTH, Nigeria. Earlier stage at lymphoma diagnosis and prompt therapeutic intervention is likely to improve survival in these patients. Future research should undertake collaborative studies to obtain comprehensive regional data and identify unique risk factors of poor outcomes among HIV-infected patients with lymphoma in Nigeria.

Abstract
OBJECTIVE To compare the laboratory performance of a HIV antibody Rapid Diagnostic Test (RDT) [Determine HIV-1/2] with an Enhanced ELISA [GENSCREEN PLUS HIV Ag-Ab] used for HIV screening among blood donors in a hospital-based transfusion centre in North Central Nigeria. METHODS The serum of four hundred and forty (440) blood donors of both sexes aged between 18 and 55 years, who fulfilled the conditions to donate blood, were serially tested for HIV using both methods. RESULT DetermineTM HIV-1/2 detected 16 (3.6%) while GENSCREEN PLUS HIV Ag-Ab ELISA detected 41 (9.3%) blood donors who were HIV sero-positive. The DetermineTM HIV-1/2 missed 25 (61%) blood donors who were positive with the GENSCREENPLUS HIV Ag-Ab ELISA. The calculated sensitivity and specificity of Determine HIV-1/2 were 39.0% and 100% respectively while the positive predictive value and negative predictive values of Determine HIV-1/2 were 100% and 94.1% respectively. CONCLUSION The HIV Antibody RDT (Determine HIV-1/2) has a very low sensitivity and therefore, inadequate in preventing transfusion transmissible HIV (TT-HIV) in a hospital-based blood transfusion service. The National Blood Transfusion Service (NBTS) in Nigeria should be equipped and supported to provide blood products screened with Enhanced ELISA as well as to embark on regular evaluation of all HIV screening assays used in the country in order to prevent counterfeit and sub standard assays and invariably reduce the risk of TT-HIV infection in the country.

Abstract
AIMS AND OBJECTIVES To determine the common aetiolog of acute bacterial meningitis in children and their antibiotic susceptibility pattern. MATERIALS AND METHODS A retrospective study with a review of cerebrospinal fluid culture reports of paediatric patients aged 0-15 years, suspected of acute meningitis in the Medical Microbiology Department of Aminu Kano Teaching Hospital, Kano, Nigeria from October 2006 to October 2009 from October 2006 to October 2009. RESULTS A positive culture bacterial isolation rate of 3.3% (n=50/1500) with prevalence of Streptococcus pneumoniae (24%), Neisseria meningitidis (22%), Escherichia coli (16%), Haemophilus influenzae (14%), Group B streptococci (8%) and Enterococci (8%) which were susceptible to ceftriaxone (96%), cefotaxime (95%) and ciprofloxacin (93%) across the bacterial isolates. Neonates were 55% (n=6.8/12.4) most at risk. CONCLUSION Neonates are the most at risk of acute bacterial meningitis. In the absence of antibiotic susceptibility report, ceftriaxone should be considered as a first choice reliable antibiotic for empirical treatment of meningitis in children, in this environment.

Abstract
INTRODUCTION The normal haemoglobin is an efficient transporter of oxygen to the tissues and carbondioxide from tissues to the lungs for elimination. Various abnormal haemoglobin variants including, the sickle cell diseases, have been described with varying sickling tendencies. AIMS This study aimed to determine the haemoglobin variants among voluntary blood donors in Jos. METHOD Records of the age, sex, Haemoglobin level, and the haemoglobin genotype of all voluntary blood donors who donated blood at the National Blood Transfusion Service Centre, Jos, Nigeria between January 2011 and April 2012; and their haemoglobin levels and protein electrophoresis determined, were reviewed. RESULTS A total of 937 blood donors, 658 (70.23%) males and 279 (29.79%) females, mean age 32.4 years, donated blood voluntarily, their haemoglobin electrophoretic patterns determined by alkaline cellulose acetate electrophoresis. Donor blood haemoglobin levels were determined by automation. Haemoglobin protein electrophoretic patterns identified among our donors were 77.70% AA, 21.88% AS, 0.22% SC, 0.11% AC and 0.11% SS. Mean haemoglobin levels of the donors according to their haemoglobin proteins electrophoretic patterns were, 150.4 +/- 12.5 gms/l for AA, 151.9 +/- 13.8 gms/l for AS and 131.1 +/- 5.0 gms/l for haemoglobin SC. CONCLUSION Determination of haemoglobin protein electrophoretic patterns of blood unit for transfusion could enhance selective blood issuing based on recipient's haemoglobin type.
