Background: Zinc, copper and selenium are known important trace elements playing a vital role as cofactors of enzymes such as superoxide dismutase and glutathione peroxide. They form part of the first line antioxidants enzymes in red blood cells and plasma. The study aimed at determining the serum levels of zinc, copper and selenium in asymptomatic sickle-cell anaemia patients. Methods: This was a case control study conducted from the specialist Haematology and Oncology Clinic 4 at the University Teaching Hospital, Lusaka, Zambia. 5mls of whole blood was collected from 46 sickle-cell anaemia patients and 46 healthy controls from Out-Patient Department after consent. Using Atomic Absorption Spectrometry, serum levels of zinc, copper and selenium was determined. Independent t-test was used to compare the means and a binary logistic regression for the likelihood of developing a sickling crisis, using SPSS version 20.Results: The mean serum levels of zinc in patients were lower 86.92±20.46mg/L against 91.33±43.23mg/L; p<0.028 of controls. Copper mean levels were 149.85±54.82mg/L against 134.32±54.16mg/L; p<0.191 of controls. Selenium mean levels were 0.100±0.041mg/L against 0.081±0.032mg/L; p<0.380 in patients compared to controls. The odds of developing one sickling crises in the past year given the levels of zinc, copper and selenium was [B = -.340, zinc Exp(B) =1.011, copper Exp(B) = 1.008, selenium Exp(B) = .000, DF = 1].Conclusion: Zinc is reduced in sickle-cell anaemia patients. The probability of developing a sickling crisis is lower in patients with higher serum levels of zinc and copper by 1.1% and 0.8% respectively.

Background: Improved medical care has led to the improved life expectancy of sickle cell anaemia (SCA) patients hence complications associated with SCA such as chronic kidney disease (CKD) are being seen more frequently. Globally, nephropathy of varying severity occurs in 5 to 18 % of the SCA population across all age groups with a third of the adults proceeding to develop CKD while over 30 % of paediatric SCA patients have CKD in Africa. The mortality rate in SCA patients CKD is high. This study sought to determine the prevalence and risk factors of CKD in SCA, information that was not available in Zambia prior to this study. This information will guide in targeting and timing of screening for CKD in SCA in children in our population. Objectives: To determine the prevalence of haematuria, proteinuria, abnormal estimated glomerular filtration rate (eGFR), CKD, and risk factors of CKD among the steady-state SCA patients aged 5 to 16 years at the University Teaching Hospital (UTH), Lusaka. Methodology: This was a prospective cross-sectional study of 197 children aged 5 to 16 years with SCA at the UTH - Lusaka conducted from August 2014 to July 2015. Demographic and clinical data were collected using a structured questionnaire. Urine and blood samples were used to determine the urine albumin creatinine ratio (ACR) and full blood count /blood biochemistry respectively. CKD was defined and determined using the Kidney Disease Outcome Quality Initiative 2012 guidelines employing urine ACR, dipstick urinalysis and eGFR. In this study, spot urine ACR and dipstick urinalysis were done and repeated three months later if initial tests were abnormal. Data was analysed using SPSS version 21. Chi-square and t-test were used to compare proportions between groups. Relation between study variables and CKD were examined using logistic regression. Results: The mean age of the participants was 9.6 years (SD ±3.6). Male to female ratio was 1:1. The median age at diagnosis of SCA was 22 months (IQR = 44). The prevalence of haematuria, proteinuria and CKD among the study participants was 14.2%, 36% and 36 % respectively. Low haemoglobin and elevated mean corpuscular volume (MCV) were associated with CKD-AOR 0.62, 95% CI; 0.46-0.84 and 1.04, 95% CI; 1.01 – 1.08 respectively. Recurrent admissions (due to VOCs, severe anaemia and febrile illness) were also risk factors associated with CKD- AOR 0.52, 95% CI; 0.27-0.98. CKD was not associated with age at enrolment, sex, age at diagnosis of SCA, recurrent Vaso-occlusive crisis (VOCs) or abnormal liver function tests. Conclusion: The prevalence of CKD among the SCA patients at UTH- Lusaka is high (36%) with lower Haemoglobin, elevated MCV and recurrent admissions being risk factors for developing CKD. SCA patients should be screened for CKD routinely at least once a year. Interventions such as the early introduction of hydroxyurea, proactive blood transfusions and ACE inhibitors can reduce the risk of CKD and its progression to end-stage renal disease.

Aim: The aim of this study was to assess some haemostatic parameters in sickle cell anaemia subjects in Rivers and Bayelsa States. Study Design: This study is a cross-sectional observational study. Place and Duration of Study: This study was carried out at the University of Port Harcourt Teaching Hospital, Rivers State, and the Federal Medical Centre, Yenagoa, Bayelsa State, between the months of February and August, 2020.  Methodology: A total of four hundred and fifty (450) subjects with age range of 1-50 years were randomly selected. There were about 200 registered patients (adults and children alike) at the sickle cell clinics of the University of Port Harcourt Teaching Hospital, and the Federal Medical Centre, Yenagoa, with an average of 4 new patients per month. The sample size was obtained using a prevalence of sickle cell anaemia of 2% and the sample size was calculated using Cochran sample size formula. Five milliliters (5ml) of venous blood sample was withdrawn from the peripheral vein in the upper limb of subjects using a standard venipuncture technique. The sample was rocked gently to mix and kept at room temperature and the haemostatic parameters (vWF, FVIII, D-dimer, L-arginine, fibrinogen, ADAMTS13) were assayed quantitatively with Bioassay Technozym kit using Microplate Reader (Labtech microplate auto ELISA plate reader, an IS0 13485:2003 CE and WHO compliance Co., Ltd. Shanghai International Holding Corp. GmbH; Europe) calibrated to a wavelength of 450 nm with strict adherence to the manufacturer's instructions, while PT and APTT were analysed with Fortress reagent and Uniscope SM801A Laboratory using water bath.Data management and statistical analyses were conducted using Statistical Analyses System SAS 9.4 (SAS Institute, Cary, North Carolina, USA) and p values less than .05were considered statistically significant. Results: The results showed the mean comparison of haemostatic parameters in sickle cell anaemia and control subjects. The comparison of haemostatic parameters showed significant(p<.05) increasesand decreases inVaso-Occlusive Crisis (VOC) and steady state respectively compared with the control group. There was statistically significantreduction in the mean comparison of L-Arginine (p<.01) in VOC) condition than steady state in relation to the control group in our study population, while D-Dimer, ADAMTS13 were also significantly reduced statistically (p<.01) in VOC condition than steady state compared with the control group. However, the mean FVIII inhibitor, Fibrinogen, PT (INR) and APTT were significantly higher (p<.01) in VOC than steady state when compared to controls with normal haemoglobin (HbAA).Correlations of haemostaticparameters by sickle cell anaemia subjects’ condition showed more significant positive correlations in VOC than steady state. Conclusion: This study showed a heightened hypercoagulability in Sickle Cell Snaemia(SCA)subjects, and further pave way for better understanding particularly the diagnostic variables underlying SCA, specific to each subject condition (steady state and VOC). Subjects with SCA, particularly during VOC, undergo significant haemostatic alterations that increase their risk of developing coagulation activation-related complications. Thus, though selected markers of coagulation were significantly different between the subject conditions, they were often significantly higher in the SCA.

Abstract Introduction: Sickle cell disease is the most common monogenetic disorder worldwide. There have been reports of endocrine dysfunction and gonadal failure among affected individuals, especially in males. The findings on ovarian reserve and failure in women with sickle anaemia has been inconsistent.Aim and objective: The aim of this study was to determine and compare the ovarian reserve of Nigerian women with and without sickle cell anaemia attending a University Teaching Hospital.Study Design: This cross-sectional study was carried out at the Adult Sickle Cell Clinic and the Community Health Clinic of the Lagos University Teaching Hospital.Methodology: A total of 166 participants who met the selection criteria, were recruited for the study. The study population consisted of two groups of women matched for age; 83 women with HbSS and 83 women with HbAA. The haemoglobin phenotypes of each participant were determined on alkaline electrophoresis (pH 8.4) before analysis. serum Anti-Mullerian Hormone (AMH) were determined using Enzyme-linked immunosorbent assay (ELISA) method (Calbiotech Inc. USA, Catalog no AM448T).Results: The mean ± SD serum Anti-Mullerian Hormone (AMH) level in women with HbSS 3.64 ± 0.65 ng/mL was lower than that of women with HbAA 7.35 ±1.19 ng/mL (p < 0.001). Serum AMH negatively correlated with age in both study groups (HbAA and HbSS). Also, a significant negative correlation was found between serum AMH and BMI in women with HbAA.Conclusion: The study showed diminished ovarian reserve in women with HbSS when compared to age-matched women with HbAA.
