Impact of Binet Staging versus Tumour Bulk on Treatment Outcome in Chronic Lymphocytic Leukaemia.

BACKGROUND: Most of the predictive tools put up to prognosticate treatment outcomes in patients with chronic lymphocytic leukaemia (CLL) are not easily available and affordable in our resource-constrained environment. AIM: The aim of this study was to evaluate the impact of staging and some tumour bulk on treatment outcomes of persons with CLL, Enugu, Nigeria. PATIENTS AND METHODS: This is a 10-year review of the CLL data from the haemato-oncology unit of a Nigerian tertiary hospital to evaluate the impact of staging and tumour bulk indicators. Data were retrieved from the case notes of 102 patients with CLL receiving care at the facility. Data of interest include basic demographic variables, clinical features including spleen size and disease staging and blood counts. Statistical analysis was done using SPSS version 22. RESULTS: The median absolute lymphocyte count (ALC) was 108.05 (confidence interval [CI] = 50.8-201.3, interquartile range [IQR] = 124.4) ×109/L, and duration of survival for the study cohort was 5.5 (CI = 3.5-31.9, IQR = 27) months. Majority (69, 79.3%) were in Stage C. The Binet stage showed a significant association with the ALC (r = 0.338; P = 0.002) but not with spleen size (r = 0.198; P = 0.056). The duration of survival only showed a significant inverse relationship with the ALC (r = 0.35, P = 0.006) but with neither the Binet stage (r = 0.103, P = 0.431) nor spleen size (r = 0.184, P = 0.116). CONCLUSION: In CLL patients, ALC at presentation correlates with the duration of survival. We recommend that the ALC at presentation be used as a prognostic marker in our clime.

The impact of COVID-19 on the birth rate in Nigeria: a report from population-based registries.

Background and objectives: Coronavirus disease 2019 (COVID-19) is a pandemic that has become a major source of morbidity and mortality worldwide, affecting the physical and mental health of individuals influencing reproduction. Despite the threat, it poses to maternal health in sub-Saharan Africa and Nigeria, there is little or no data on the impact it has on fertility, conception, gestation and birth. To compare the birth rate between pre-COVID and COVID times using selected months of the year. Materials and methods: This was a secondary analysis of cross-sectional analytical study data from the birth registries of three tertiary hospitals, comparing two years [2019 (Pre-COVID)] versus [2020 (COVID era)] using three months of the year (October to December). The data relied upon was obtained from birth registries in three busy maternity clinics all within tertiary hospitals in South-East Nigeria and we aimed at discussing the potential impacts of COVID-19 on fertility in Nigeria. The secondary outcome measures were; mode of delivery, booking status of the participants, maternal age and occupation. Results: There was a significant decrease in tertiary-hospital based birth rate by 92 births (P = 0.0009; 95% CI: -16.0519 to -4.1481) among mothers in all the three hospitals in 2020 during the COVID period (post lockdown months) of October to December. There was a significant difference in the mode of delivery for mothers (P = 0.0096) with a 95% confidence interval of 1.0664 to 1.5916, as more gave birth through vaginal delivery during the 2020 COVID-19 period than pre-COVID-19. Conclusion: Tertiary-hospital based birth rates were reduced during the pandemic. Our multi-centre study extrapolated on possible factors that may have played a role in this decline in their birth rate, which includes but is not limited to; decreased access to hospital care due to the total lockdowns/curfews and worsening inflation and economic recession in the country.

A Systematic Review and Meta-Analysis of the Prevalence of Triplex Infections (Combined Human Immunodeficiency Virus, Hepatitis B Virus, and Hepatitis C Virus) among Pregnant Women in Nigeria.

Objective: We systematically identified the prevalence of triplex infections (combined human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV)) in pregnancy. Methods: To gather information on the frequency of triplex infections, we searched the databases of PubMed, CINAHL, and Google Scholar. Without regard to language, we utilized search terms that covered HIV, HBV, HCV, and pregnancy. Pregnant women with triplex infections of HIV, HBV, and HCV were included in studies that also examined the prevalence of triplex infections. Review Manager 5.4.1 was employed to conduct the meta-analysis. Critical appraisal and bias tool risk data were provided as percentages with 95% confidence intervals (95% CIs), and I2 was used as the statistical measure of heterogeneity. The checklist was created by Hoy and colleagues. The study protocol was registered on PROSPERO, under the registration number CRD42020202583. Results: Eight studies involving 5314 women were included. We identified one ongoing study. Pooled prevalence of triplex infections was 0.03% (95% CI: 0.02-0.04%) according to meta-analysis. Subgroup analysis demonstrated a significantly high prevalence of 0.08% (95% CI: 0.06-0.10%; 3863 women) in HIV-positive population than 0.00% (95% CI:-0.00-0.00; 1451 women; P < 0.001) in general obstetric population. Moreover, there was a significant difference in the pooled prevalence between studies published between 2001 and 2010 and between 2011 and 2021 (0.14% (95% CI: 0.12 to 0.16 versus 0.03% (95% CI: 0.02 to 0.04%; P < 0.001))) and participants recruited in the period between 2001 and 2011 and between 2012 and 2021 (0.13% (95% CI: 0.05 to 0.21; p=0.002 versus 0.00% (95% CI: -0.00 to 0.00%; p=1.00))), respectively. Conclusion: The combined prevalence of prenatal triplex infections was 0.03%, with rates notably higher among the group of pregnant women who were HIV-positive and during the recruitment period that took place before 2012. This prevalence still necessitates screening for these infections as necessary.

Efficacy and safety of Mojeaga remedy in combination with conventional oral iron therapy for correcting anemia in obstetric population: A phase II randomized pilot clinical trial.

BACKGROUND: To our knowledge, there is no prior randomized trial on the efficacy of Mojeaga remedy (a special blend of Alchornea cordifolia, Pennisetum glaucum and Sorghum bicolor extracts) when co-administered with standard-of-care for correction of anemia in obstetrics practice. This study determined the efficacy, safety and tolerability of Mojeaga as adjunct to conventional oral iron therapy for correction of anemia in obstetric population. METHODS: A pilot open-label randomized clinical trial. Participants with confirmed diagnosis of anemia in three tertiary hospitals in Nigeria were studied. Eligible participants were randomized 1:1 to either Mojeaga syrups 50 mls (200mg/50mls) administered three times daily in conjunction with conventional iron therapy (Mojeaga group) for 2 weeks or conventional iron therapy alone without Mojeaga (standard-of-care group) for 2 weeks. Repeat hematocrit level were done 2 weeks post-initial therapy. Primary outcome measures were changes in hematocrit level and median hematocrit level at two weeks post therapy. Maternal adverse events and neonatal outcomes (birth anomalies, low birthweight, preterm rupture of membranes and preterm labor) were considered the safety outcome measures. Analysis was by intention-to-treat. RESULTS: Ninety five participants were enrolled and randomly assigned to the Mojeaga group (n = 48) or standard-of-care group (n = 47). The baseline socio-demographic and clinical characteristics of the study participants were similar. At two weeks follow-up the median rise in hematocrit values from baseline (10.00±7.00% vs 6.00±4.00%;p<0.001) and median hematocrit values (31.00±2.00% vs 27.00±3.00%;p<0.001) were significantly higher in the Mojeaga group. There were no treatment-related serious adverse events, congenital anomalies or deaths in the Mojeaga group and incidence of other neonatal outcomes were similar (p>0.05). CONCLUSION: Mojeaga represents a new adjuvants for standard-of-care option for patients with anemia. Mojeaga remedy is safe for treating anemia during pregnancy and puerperium without increasing the incidence of congenital anomalies, or adverse neonatal outcomes.

Iron supplementation and blood donation in Nigeria: Effect on Hemoglobin, red cell indices, and iron stores - The ranferon™ study.

Background: Iron-deficiency anemia is an important limiting factor to a sustainable supply of blood units, especially in low- and middle-income countries. Blood transfusion practice in Nigeria is poorly developed and structured with paucity of voluntary nonremunerated blood donors and high rate of donor deferrals resulting from low hemoglobin (Hb) levels. Aims: This study aimed to assess the effect of daily supplementation of iron using Ranferon-12 on Hb level, red blood cell (RBC) indices, iron level, ferritin level, and Hb recovery in blood donors in Nigeria. Methodology: This longitudinal study was conducted at a tertiary hospital blood transfusion center from March to July 2020. Blood samples of regular donors were collected at three points in the study for the measurement of Hb and hematocrit (HCT); RBC indices including mean cell volume (MCV), mean cell hemoglobin (MCH), and Mean cell haemoglobin concentration (MCHC); and iron stores including serum iron, serum ferritin, and serum transferrin. The first point was at recruitment before donation of one unit of blood; the second point after the blood donation; and the third point at 6 weeks post blood donation. Following donation, participants were placed on Ranferon capsules (iron fumarate - 100 mg elemental iron) and 100 mg of tablet Vitamin C, for 6 weeks. Results: There was a moderate significant positive correlation between administration of Ranferon and change in the values of HCT, MCV, MCH, red cell distribution width, ferritin, and transferring (P < 0.05). Percentage recovery of Hb, red cell indices, and iron stores parameters after 6 weeks of daily Ranferon ranged between 89% and 100%. Conclusion: Iron supplementation using Ranferon capsule daily for 6 weeks enhances recovery of Hb, red cell indices, and iron stores with attainment of benchmark Hb levels for donation.

Résumé Contexte: L'anémie ferriprive est un facteur limitant important pour un approvisionnement durable en unités de sang, en particulier dans les pays à revenu faible et intermédiaire (PRFI). La pratique de la transfusion sanguine au Nigéria est peu développée et structurée avec une pénurie de donneurs de sang volontaires non rémunérés (VNRD) et un taux élevé d'exclusion des donneurs résultant de faibles taux d'hémoglobine (Hb). Objectifs: Cette étude visait à évaluer l'effet de la supplémentation quotidienne en fer à l'aide de Ranferon-12 sur le taux d'hémoglobine (Hb), les indices de globules rouges (RBC), le taux de fer, le taux de ferritine et la récupération de l'Hb chez les donneurs de sang au Nigeria. Méthodes: Cette étude longitudinale a été menée dans un centre de transfusion sanguine d'un hôpital tertiaire de mars à juillet 2020. Des échantillons de sang de donneurs réguliers ont été prélevés à trois points de l'étude pour mesurer l'Hb, l'hématocrite (HCT) ; Les indices RBC, y compris le volume cellulaire moyen (MCV), l'hémoglobine cellulaire moyenne (MCH) et la concentration moyenne d'hémoglobine cellulaire (MCHC) ; et les réserves de fer, y compris le fer sérique, la ferritine sérique et la transferrine sérique. Le premier point concernait le recrutement avant le don d'une unité de sang ; deuxième point ­ après le don de sang ; et troisième point ­ six semaines après le don de sang. Après le don, les participants ont reçu des gélules de Ranferon (fumarate de fer --100 mg de fer élémentaire) et 100 mg de vitamine C en comprimé, pendant 6 semaines. Résultats: Il y avait une corrélation positive significative modérée entre l'administration de Ranferon et le changement des valeurs de HCT, MCV, MCH, la largeur de distribution des globules rouges, la ferritine et le transfert (p < 0,05). Le pourcentage de récupération de l'Hb, des indices de globules rouges et des paramètres des réserves de fer après 6 semaines de Ranferon quotidien variait entre 89 % et 100 %. Conclusion: La supplémentation en fer à l'aide de la capsule de Ranferon quotidiennement pendant 6 semaines améliore la récupération de l'Hb, des indices de globules rouges et des réserves de fer avec l'atteinte des niveaux d'hémoglobine de référence pour le don.

Determinants of Obstetricians' Pattern of Care for Sickle Cell Disease in Pregnancy.

Background: Pregnancy in sickle cell disease (SCD) is high risk. With improved comprehensive obstetric care, pregnant females with SCD can achieve successful pregnancy outcomes, especially in resource-poor settings. Objectives: To determine the predictors of Obstetricians' pattern of care for SCD in pregnancy in Nigeria. Materials and Methods: Self-administered, pre-tested, pre-validated questionnaires containing 18 questions on demographic details of obstetricians, and their pattern of practice towards antenatal care for pregnant SCD patients were distributed to attendees of the 2018 conference of the Society of Obstetrics and Gynaecology of Nigeria (SOGON). Regression analysis was done to determine the possible predictors, and a significant level was <0.05. Result: Almost all the respondents (98.4%) considered pregnancy in SCD as high risk, and 96.2% proposed for preconception care in a tertiary hospital. The majority, (62%) agreed that antenatal visits in the first and second trimesters should be more frequent. The majority (96.2%) reported they would routinely order urine tests among other investigations. Majority of respondents,74.9% and 98.4% knew that foetal medicine specialists and haematologists should be part of preconception care team, respectively. Respondents' practice centre and designation, significantly contributed to their "willingness to consult a haematologist" (P = 0.004)," and willingness to consult a foetal specialist" (P = 0.047), while practice centre and practice population significantly contributed to their response to "ideal centre for management of SCD pregnancy": (P = 0.049), (P = 0.024) respectively. Conclusion: Obstetricians' level of training, practice centre, and practice population of pregnant women with SCD are significant contributors to their pattern of care towards antenatal care for pregnancy in SCD.

Does Sickle Cell Disease Protect against HIV Infection: A Systematic Review.

OBJECTIVE: The aim of this systematic review was to investigate whether sickle cell disease (SCD) protects against human immunodeficiency virus (HIV) infection by determining the association between SCD and the incidence and virulence of HIV infection. METHODS: This is a systematic review that used MEDLINE, PubMed, CINAHL, and Academic Search Complete as data sources. Articles describing the relationship of SCD with HIV infection were included in this review. The effect measures were converted to correlation coefficients and synthesized accordingly to examine the putative protective role of SCD against HIV infection. Independent full-text screening and data extraction were conducted on all eligible studies. The risk of bias was assessed using the mixed methods appraisal tool. We employed a random-effects model of meta-analysis to estimate the pooled prevalence. We computed Cochrane's Q statistics, I2, and prediction interval to quantify effect size heterogeneity. RESULTS: SCD reduces the risk of HIV infection by 75% (odds ratio [OR] = 0.25; r = -0.36, p < 0.001; I2 = 71.65). There was no publication bias (Egger's t value = 0.411; p = 0.721). Similarly, risk of HIV virulence was reduced by 77% (OR = 0.23; r = -0.38; p < 0.001; I2 = 63.07). The mechanisms implicated in the protective influence of SCD include autosplenectomy, reduced CCR5 expression, and increased expression of heme and iron-regulated genes. CONCLUSIONS: SCD appears to protect against HIV infection and slows HIV progression.

Cesarean section rate and outcomes during and before the first wave of COVID-19 pandemic.

Objectives: The objective of the study was to assess how the current COVID-19 pandemic has affected cesarean section (C-section) rates, indications, and peripartum outcomes. Methods: This was a retrospective cross-sectional study that compared a 3-month rates of and indications for C-sections at three tertiary health care institutions in Nigeria before (October 2019-December 2019) and during the first wave of COVID-19 pandemic (March 2020-May 2020). Primary outcomes were C-section rate and indications between the two periods. Data were analyzed using SPSS 26.0 IBM Corporation. Rates and odds ratios with 95% confidence intervals were used to quantify indications and peripartum outcomes and statistical significance was accepted when p value was <0.05. Results: The baseline characteristics of the two groups were similar. The C-section rate during the COVID-19 period was significantly less than the period prior to the pandemic (237/580, 40.0% vs 390/833, 46.8%; p = 0.027). The rates of postdatism (odds ratio = 1.47, 95% confidence interval = 1.05-2.05, p = 0.022), fetal distress (odds ratio = 3.06, 95% confidence interval = 1.55-6.06, p = 0.017), emergency C-section (odds ratio = 1.43, 95% confidence interval = 1.01-2.05, p = 0.042), and anemia (odds ratio = 1.84, 95% confidence interval = 1.12-3.03, p = 0.016) were significantly higher during the pandemic than prepandemic. Conclusion: The overall C-section rate during the first wave of COVID-19 was significantly lower than the prepandemic period. There were higher rates of postdatism, fetal distress, emergency C-section, and postpartum anemia. Further studies on this changing C-section trend during the pandemic are needed.

Phenotypic characterisation and associations of leg ulcers in adult sickle cell patients.

Sickle leg ulcer (SLU) occurs as a result chronic occlusion of the vasculature with consequent necrosis of the skin and subcutaneous tissue usually in proximity of the malleoli. The description of clinical associations and the simultaneous occurrence of SLU and other complications of SCD compared to the non-SLU patients was the aim of this work. A total of 272 (60.8% males and 39.2% females) patients were captured during this time period out of which 68 (51 males and 17 females) had SLU out of whom 20 patients had bilateral leg ulcers. Prevalence of SLU was 25% and the median age of patients was 25 years, frequency of crisis 2 per annum and 44 (74.6%) had been transfused in the past. Median Hb of the group was 7.6 g/dl and 25% had values lower than 6.5. The occurrence of other complications in SLU patients was as follows; 10 had AVN, 9 priapism, 8 had osteomyelitis, 6 nephropathy, stroke 2, osteoarthritis 4 and cholelithiasis 4. There was a significant relationship between the occurrence of SLU and gender of the patient being more in 67males-Likelihood ratio 4.610 (p = 0.032) and the occurrence of pulmonary hypertension-Likelihood ratio 4.762 (p = 0.029). There was no significant association between the occurrence of SLU and other complications of SCD. Leg ulcer patients have a median age of 25 years with a prevalence of 25% but do not necessarily show other features of severe disease phenotypes. SLU patients were more likely to develop pulmonary hypertension. Further studies on impact of environmental factors on the occurrence of SLU are needed to further evaluate its aetiology.

Clinical screening for menorrhagia and other bleeding symptoms in Nigerian women.

Objective: The objective of the study was to evaluate the prevalence of perceived bleeding symptoms in Nigerian women and the usefulness of a simple clinical screening tool for bleeding symptoms. Materials and Methods: A population-based cross-sectional survey of 1524 women of 16-50 years in Southeast Nigeria using a structured, prevalidated, pretested questionnaire was conducted. Results: A total of 1524 (85%) women responded with the mean age of 26 (10.6) years. Prevalence of bleeding symptoms was 24.6% and 11% of the women reported a positive family history of bleeding symptoms. There was a significant association between having a positive family history of bleeding disorder and experiencing bleeding symptoms (adjusted odds ratio: 0.12, 95% confidence interval: 0.06-0.22 P < 0.0001). Two hundred and six women experienced at least one bleeding symptom, 125 (8.2%) experienced at least two, whereas 43 (2.8%) experienced >3 bleeding symptoms. The most common perceived bleeding symptom was heavy menstrual bleeding (HMB) present in 83 women (22.2%), 141 (9.3%) reported a past history of HMB, 202 (13.3%) had heavy bleeds during most of their monthly cycle, and 351 (23%) requiring resuscitation with blood support. Conclusion: The prevalence of perceived bleeding symptoms among women is high, and HMB is the most common bleeding symptom. This clinical screening tool is easy and cost-effective in routinely identifying women with bleeding symptoms needing further hemostatic and obstetrics evaluation.

RésuméObjectif: L'objectif de l'étude était d'évaluer la prévalence des symptômes hémorragiques perçus chez les femmes nigérianes et l'utilité d'un outil de dépistage clinique simple des symptômes hémorragiques. Matériel et méthodes: enquête transversale auprès de la population auprès de 1 524 femmes de 16 à 50 ans dans le sud-est du Nigéria à l'aide d'un questionnaire structuré, prévalidé et prétesté. Résultats: Un total de 1524 (85%) les femmes ont répondu avec l'âge moyen de 26 (10,6) ans. La prévalence des symptômes hémorragiques était de 24,6% et 11% des femmes ont signalé un antécédents familiaux positifs de symptômes hémorragiques. Il y avait une association significative entre avoir des antécédents familiaux de saignement positifs trouble et présentant des symptômes hémorragiques (rapport de cotes ajusté: 0,12, intervalle de confiance à 95%: 0,06­0,22 P <0,0001). Deux cent et six femmes ont présenté au moins un symptôme de saignement, 125 (8,2%) en ont eu au moins deux, tandis que 43 (2,8%) ont eu> 3 saignements symptômes. Le symptôme de saignement perçu le plus courant était le saignement menstruel abondant (HMB) présent chez 83 femmes (22,2%), 141 (9,3%) ont signalé des antécédents de HMB, 202 (13,3%) ont eu des saignements abondants pendant la majeure partie de leur cycle mensuel et 351 (23%) ont dû être réanimés avec support sanguin. Conclusion: la prévalence des symptômes hémorragiques perçus chez les femmes est élevée et le HMB est le plus courant symptôme de saignement. Cet outil de dépistage clinique est simple et économique pour identifier systématiquement les femmes présentant des symptômes hémorragiques nécessitant évaluation hémostatique et obstétrique plus poussée.

Hyperhaemolytic Syndrome in Sickle Cell Disease: Clearing the Cobwebs.

Sickle cell disease (SCD) presents with a dynamic background of haemolysis and deepening anaemia. This increases the demand for transfusion if any additional strain on haemopoiesis is encountered due to any other physiological or pathological causes. Patients with cerebrovascular accidents are placed on chronic blood transfusion; those with acute sequestration and acute chest syndrome are likewise managed with blood transfusion. These patients are prone to develop complications of blood transfusion including alloimmunization and hyperhaemolytic syndrome (HHS). This term is used to describe haemolysis of both transfused and "own" red cells occurring during or post-transfusion in sickle cell patients. Hyperhaemolysis results in worsening post-transfusion haemoglobin due attendant haemolysis of both transfused and autologous red cells. The mechanism underlying this rare and usually fatal complication of SCD has been thought to be secondary to changes in the red cell membrane with associated immunological reactions against exposed cell membrane phospholipids. The predisposition to HHS in sickle cell is also varied and the search for a prediction pattern or value has been evasive. This review discusses the pathogenesis, risk factors and treatment of HHS, elaborating on what is known of this rare condition.

Perception of problem based learning versus conventional teaching methods by clinical medical students in Nigeria.

INTRODUCTION: Problem-based learning (PBL) method which was introduced about 50 years ago in Canada is beginning to gain acceptance over conventional teaching method (CTM) worldwide in medical education but still remains unpopular in Nigeria. This study aims to determine the perception of clinical medical students to the use of both learning methods in pathology courses. METHODS: A cross-sectional quantitative survey was conducted in four Nigerian universities drawn from four regions of the country. Data were collected using pretested semi-structured self-administered questionnaires. RESULTS: The study included 310 respondents, 182(58.7%) males and 128(41.3%) females. Of all the participants, 257(82.9%) had heard of PBL prior to the study and 260(83.9%) thought it suitable for teaching and learning Pathology. Majority of participants, 221(71.3%) preferred a combination of both PBL and CTM while 238(76.8%) thought PBL suitable for all medical students. Some identified factors capable of enhancing adaptation of PBL into medical curriculum include conducive quiet spaces for learning and availability of computers with internet facilities for students' use. CONCLUSION: Participants demonstrated high level of awareness of PBL and thought it suitable for all medical students. Availability of computers and up-to-date libraries with internet and audio-visual facilities could enhance adaptation of PBL into medical curriculum in Nigeria.

Clinical and Laboratory Predictors of Frequency of Painful Crises among Sickle Cell Anaemia Patients in Nigeria.

INTRODUCTION: The severity of Sickle Cell Anaemia (SCA) in terms of frequency of painful Vaso-Occlusive Crises (VOC) may be affected by clinical and haematological parameters amongst others. Elucidation of these factors in a given disease prevalent environment is necessary for prompt and effective management of patients with frequent painful VOC. AIM: This study aimed at determining the clinical and laboratory predictors of frequency of painful VOC among SCA patients in Enugu, Southeastern Nigeria. MATERIALS AND METHODS: It was a cross-sectional study of 100 consecutive SCA patients receiving care at the University of Nigeria Teaching Hospital, Enugu, Nigeria between May 2012 and February 2014. The eligible patients were categorized into two groups namely; Group A and Group B. Group A/study group (severe disease) comprised SCA patients who had experienced three or more painful crises (≥3 crises) in the last one year preceding the study but, currently in steady state, while Group B/control group (mild-moderate disease), comprised SCA patients matched for age, sex, highest educational status, and occupation but who have had no painful crisis or had only one or two painful crises (0-2 crises) in the last one year preceding the study and currently in steady state. RESULTS: The overall mean age of the patients was 18.4±12.2 (range=2-52) years. The mean values of the haematological parameters including haemoglobin concentration, white cell count, platelet count, and neutrophil count were significantly higher in those with severe crises than mild-moderate crises (p<0.05). Sickle cell related complications including Avascular Necrosis (AVN) and leg ulcers were significantly higher in the study group than the control group (p<0.05). CONCLUSION: There was significant association between the frequency of crises and haemogblobin level, platelet and neutrophil counts and some clinical parameters: AVN, nephropathy and stroke. Future preventive interventions for reduction in frequency of crisis amongst patients with SCA could be targeted at controlling the blood levels of the identified haematological parameters.
