A 76-year-old female patient presented with pruritic and hyperemic rashes in her whole body, was diagnosed with MDS concurrent with B-CLL as a result of determined leucocytosis(White blood cell count: 52.200/mm<sup>3</sup>; 57% lymphocytosis, 33% monocytosis) in the complete blood count. She also had a history of receiving chemoradiotherapy for cervical cancer in her past medical history. A biopsy was performed from her rashes and histopathological findings showed chronic lymphocytic vasculitis. Cases of lymphocytic cutaneous vasculitis associated with hematological malignancies have been reported. Coexistence of B-CLL and MDS is an independent entity from the management of CLL, but receiving chemotherapy for a carcinoma is a risk factor for developing MDS. So, we aimed to present a case, who has a risk factor for developing MDS and skin involvement of B-CLL together, with literature and emphasize that two different hematological malignancies that develop simultaneously or at different times in the same patient may coexist. This rare condition should be considered in lymphocytosis and blast association.</p> Muzeyyen Ak Aslaner, Birsen Sahip ##submission.copyrightStatement## Fri, 28 May 2021 00:00:00 +0000 Early T-cell Precursor Acute Lymphoblastic Leukemia- A Neoplasm with Dual Lineage Phenotype- Case Study of Two Patients <p>Early T-cell Precursor Acute Lymphoblastic Leukemia (ETP-ALL) is a subtype of T-ALL/LBL which is derived from thymic cells at the early T-cell precursor (ETP) differentiation stage that have the potential to differentiate into multiple lineages, including lymphoid and myeloid. ETP-ALL accounts for 15% of childhood T-ALL and 10-30% of adult T-ALL. It has characteristic&nbsp; immunophenotypic expression&nbsp; of CD7, a lack of CD1a and CD8, weak expression of CD5 (with &lt;75% positive blasts), and positive expression of one or more stem cell or myeloid markers including CD117, HLADR, CD13, CD33, CD11b or CD65.

They were under-graduate and post-graduate students of Rivers State University, Port Harcourt, Nigeria. Five major ethnic groups were considered which included Ikwerre, Ogoni, Ijaw, Etche and Ogba. Their demographic information was collected using a sample register and a questionnaire. Samples were collected from the antecubital vein. 10ml of blood was collected, 5ml was transferred into EDTA sample bottle (Ethylene diamine tetracetic acid) while 2ml was dispensed into plain bottle and labeled accordingly. Serological testing including HIV (RVS) screening, HBsag, HCV and VDRL were all done immediately after samples were collected. The remaining sample was analyzed using genotyping of Human Platelet Antigens by High Resolution Melting Curve Analysis Polymerase Chain Reaction (HRM-PCR). The melt curve analysis was done using the MicPCR software while the frequency analysis was done using Number Cruncher Statistical Software (NCSS) Version 13. Graph Pad Prism Version 8.0.2 was used to determine the statistical significance between the various HPA genotypes and the ethnic groups and p-values of &lt;<em>.05</em> were considered to be statistically significant. Results were presented in percentages, mean+/- standard deviation and in tables</p> <p><strong>Results:</strong> The results showed that HPA-4 and HPA-5 a/a and b/b were the highest among Etche (20.0% each), followed by HPA-2 and HPA-3 at 16% each for b/b and HPA-1 a/a and a/b had 10.0% and 6.7% respectively, and HPA-1 b/b, HPA-2 a/b and HPA-3 a/a had 3.3% respectively. The HPA pattern for Ijaw was highest at HPA-4 a/a (15.7%), followed by HPA-5 b/b (15.3%) and the least was HPA-2 b/b (11.4%). The pattern for Ikwerre was highest for HPA-5 b/b (20.0%) and least for HPA-4 b/b and HPA-2 a/a (0.8% each). The HPA pattern for Ogba was highest for HPA-5 b/b (20.0%) and least for HPA-3 a/a and HPA-2 a/a (0.0% each), while the pattern for Ogoni is highest for HPA-5 b/b (19.1%) and least for HPA-5 a/b and HPA-3 a/b (0.9%). The HPA alleles showed that HPA-1 a/b was highest. 42 (40.4%), followed by HPA-1 a/a 34 (32.7%) and HPA-1 b/b 28 (26.9%), and the least was 3% for HPA-2 a/b. The highest for HPA-2 was b/b, 60 (57.7%) and the least is a/a, 2 (1.9%), while the highest for HPA-3 was also b/b, 75 (72.1%) and the least was a/a 3 (2.9%).

Enzyme-.linked immunosorbent assay (ELISA) was used to determine interleukin-6 (IL-6). The data generated were analysed by one-way analysis of variances (ANOVA) using Statistical Package for Social Sciences (SPSS) version 21; Relationship existing between parameters were analysed using table curve 2D (Systat USA).</p> <p><strong>Results:</strong> Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) Interleukin-6 (IL-6) and thiobarbituric acid reactive substances (TBARS) were all significantly higher in seropositive young adult subjects (P&lt;0.05) than the seronegative young adult control subjects. Glutathione (GSH) was significantly reduced in the seropositive young adult subjects (P&lt;0.05) than the seronegative young adult control subjects. In all the parameters measured, Naïve and ART subjects were similar in trend to ELD65+ subjects suggesting immune ageing. The antioxidant parameter GSH had an inverse relationship with the inflammatory (ESR, CRP and IL-6) and oxidative stress (TBARS) parameters. This relationship was logistic and followed a logistic dose-response relationship and a sigmoidal association.</p> <p><strong>Conclusion:</strong> We conclude that Erythrocyte sedimentation rate, C-reactive protein, Interleukin-6 (IL-6), Glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) are useful parameters to assess immune ageing, and are related logistically in humans.</p> Precious Nc.

Cases were those with ICI while controls were those without ICI. VOC was diagnosed by history and examination with Faces Pain Scale – Revised. Electrocardiography and cTnT estimation were done. Cut-off level (97.5<sup>th</sup> percentile) of cTnT was obtained from age and sex-matched healthy children with haemoglobin genotype-AA. Serum cTnT analysis was by electrochemiluminescence immunoassay. Ischaemic ECG assessment was according to World Heart Federation criteria.</p> <p><strong>Results:</strong> Fifty-six children with SCA participated among who 27(48.2%) were cases and 29(51.8%) controls. Ischaemic ECG (71.4%) and elevated cTnT (57.2%) were significantly related (<em>P</em>=.01). All cases had severe pain (<em>P</em>=.02) and accounted for &gt;50% of those with chest pain (<em>P</em>=.25). Controls had more &lt; 3 pain episodes per annum than cases while frequent VOC (≥3 pain episodes per annum) occurred more in the cases though the differences were not statistically significant.</p> <p><strong>Conclusion:</strong> Severe pain with frequent VOC is associated with ICI even in the absence of chest pain in children with SCA. Regular electrocardiography and cTnT measurement will identify at-risk children for adequate management.</p> Nlemadim, Anthony Chibueze, Okpara, Henry Chima, Uzomba, Chigozie Ikechukwu, Anah, Maxwell Udo, Odey, Friday Akwagiobe, Meremikwu, Martin Madu ##submission.copyrightStatement## Mon, 07 Jun 2021 00:00:00 +0000 Assessment of Some Systemic Inflammatory Markers and Haematological Parameters among Pregnant Women in Different Trimesters in Port Harcourt, Nigeria <p>Pregnancy is a physiological condition that is associated some changes in haematological and immunological parameters. This study evaluated the levels of some systemic inflammatory and haematological parameters in pregnant women in Port Harcourt, Nigeria. A total of 275 pregnant women of age 20 to 70 years and 87 apparently healthy non-pregnant control subjects were involved in this study. Five millilitres (5ml) of blood were collected from the subjects into EDTA bottle for the evaluation of the parameters. ELISA technique was used in the determination of soluble transferrin receptor while Sysmex automation was used for the determination of the other parameters. The mean value of parameters for the study subjects were Hb( 9.05± 1.22g/dl), sTfR( 21.16± 9.11nmol/L), NLR (2.69 ± 0.91), PLR (8.78 ± 2.97), while for control subjects were Hb( 12.19± 0.66g/dl), sTfR( 18.21± 3.77nmol/L), NLR (2.86 ± 0.11), PLR (9.62 ± 2.79). The mean sTfR levels in pregnant women was significantly lower (p=0.001) than in control subjects. The pregnant women also had significantly lower values of Hb (p=0.0001), and PLT (p=0.017). According to trimesters, the levels of sTfR significantly increased with trimester (p=0.002), while that of PLR significantly increased in the second trimester (p=0.006). However, there were no significant differences in the levels of Hb (p=0.185) and NLR (p=0.70) among the trimesters. The results indicate that the pregnant women did not have levels of parameters that may indicate negative outcomes of pregnancy. It is recommended that systemic parameters be monitored among pregnant women in order to help in their medical management.</p> Nyebuchi Jonathan, Erens Spiff Ekprikpo, Onengiye Davies-Nwalele, Lynda K.

The haematinic efficacy of the leaves of this plant was examined in this study.&nbsp; A total of 43 rats were procured, 13 rats were used for lethal dose (LD<sub>50</sub>) studies while the remaining 30 rats were grouped into six groups of five rats each and allowed to acclimatize for two weeks.&nbsp; Groups 1 served as control and were administered 2ml/kg of the extract vehicle, group 2 served as negative control, groups 3 and 4 served as test group and were administered with 50 mg per body weight of <em>Fleurya aestuans</em> leaf extract and 200 mg per body weight of same extract, while group 5 and 6 were administered with 0.23 ml per body weight of bioferon and 100 mg per body weight of Kaempferol respectively. Phenyl hydrazine was used to induce the anaemia in all the groups; the extract was prepared and administered orally using oral gavage. Blood samples were collected through ocular puncture after 14 days and analysed for haematological parameters using standard manual methods. Results showed that the extract significant (P &lt; 0.05) enhanced the low levels RBC counts, Hb concentration, PCV, SOD, CAT and GSH levels but reduced the abnormally elevated levels of MCV, MCHC, MDA, WBC and Platelets counts. The oral administration of <em>Fleurya aestuans</em> leaf extract could be useful both in boosting blood parameters and combating diseases irrespective of the anaemia and leukocytosis caused by phenylhydrazine therapy.</p> C.

The exposure of the environment to dumpsite leachate may occur in different ways, such as uncontrolled overflow, rainfall and infiltration. This study therefore, attempts to determine the possible effects of (Eliozu) dumpsite leachates on some haematological parameters in Wistar rats. 25 Wistar rats weighing between 180g and 250g were divided into five groups of 5 animals each. Groups are as follows: Group 1: received 1ml of commercial bottle water, Group 2: received near-by borehole water, Group 3: received 10% of leachate concentrations, Groups 4 and 5: received 50% and 100% of leachate concentrations every 24 hours for 90 consecutive days. At the end of the gavaging of the leachates, blood samples were collected for heamatological parameters analysis using automated method. Results obtained shows a significant (p&lt;0.001) reduction in some hematological parameters compared with control. Paradoxically, the mean corpuscular volume (MCV), red blood cell distribution width-standard deviation and red blood cell distribution width-coefficient of variation show significant increase (p&lt;0.001) compared with the control. There were also significant decreases in weights of the experimental animals while compared with the control group. Eliozu dumpsite leachates demonstrated some toxicological potentials on Red Blood Cells (RBCs) and RBC indices; White Blood Cells (WBCs) and WBC Differentials in Wistar rats. We recommend further studies in this regard.</p> I. I. Weleh, I. E. Weleh, I. K.

Without treatment, it is inexorably fatal. However with the availability of current definitive treatment options, patients’ clinical outcome is improving globally.</p> <p><strong>Objective: </strong>To determine the prevalence and outcome of aplastic anaemia in children and adults, over a five-year period, at University of Uyo Teaching Hospital (UUTH), Uyo, Nigeria.</p> <p><strong>Methods:</strong> This was a prospective study. We reviewed the cases of acquired aplastic anaemia managed in our hospital over a period of five years. Data analysis was done using the Statistical Package for Social Sciences (SPSS) version 23.</p> <p><strong>Results: </strong>A total of twelve cases were treated for aplastic anaemia during the period under review, giving an annual incidence of 2.4 cases per year. The ages of the patients ranged from 12 to 56 years (mean 27.8 12.3 years) with a male to female ratio of 2.1. At presentation, they had a haemotocrit of 14.583.11, white cell count of 2.380.44, absolute neutrophil count of 0.300.17, platelet count of 18.426.35, reticulocyte count of 0.930.67. Nine (75%) patients had severe AA while three (25%) patients had very severe AA at diagnosis. Management consisted of transfusion support with unbanked packed red cells and platelet concentrate, antibiotics, antifungal and antiviral agents, cyclosporin and methylprednisolone. The patients were all blood transfusion dependent. None of the patients benefited from bone marrow transplantation and anti-thymocyte globulin. The mean survival was 10.582.19 months with a mortality rate of 0.24%.</p> <p><strong>Conclusion:</strong> There is compelling need for the Federal Government to ensure that bone marrow/stem cell transplantation centres are available and accessible nationwide, and to make drugs such as cyclosporin and anti-thymocyte globulin affordable or free to reduce the high mortality associated with the condition.</p> Idongesit Samuel Akpan, Sony-Shakins Jimmy Umotong, Eniefiok Hezekiah Jumbo, Ajayi Oyedele Oyewumi ##submission.copyrightStatement## Fri, 01 Oct 2021 00:00:00 +0000 Leukocyte Profile of Children Hospitalized in Neonatology Services for Suspected Infection in Kinshasa City, Democratic Republic of the Congo <p>Neonatal infection (NI) remains a public health problem of concern because of its frequency and severity, which is related to the immuno-incompetence of the newborn and the risk of mortality, which is in the order of 10% to 30%. According to the World Health Organization (WHO), 30 to 40% of these newborn deaths are due to neonatal infections of bacterial origin. The present work was initiated with the aim of establishing the leukocyte profile of sick newborns with hyperthermia or hypothermia, in neonatology services for a better management of the newborn. The cross-sectional study was conducted in Kinshasa, capital of the Democratic Republic of the Congo (DRC) of a period from January 01 to December 31, 2018 with a sample consisting of 218 newborns from 0 to 29 days admitted in the neonatology service. The software Microsoft Excel 2010 and SPSS for Windows version 22.0 served us in the encoding and analysis of data. The results obtained in this study presented the cells of the white lineage, then explained the infections in neonatology while examining the pathological variations of the different types of white blood cells. This study also showed that there is a lack of concordance between the clinical (181 or 83% of newborns) and biological (126 newborns with infection or 57, 8%) with statistically significant evidence.</p> Rita Bokemposila, Clément L.
