Despite the fact that one year has passed since the onset of the epidemic and many treatment agents have been tried, there is still no approved treatment. Convalescent plasma therapy is a passive immunization method and holds promise in the treatment of COVID-19. In this study, we observed that asymptomatic COVID-19 infection was effectively treated with convalescent plasma in a young patient with a diagnosis of Hodgkin lymphoma, acute renal failure also who received R-DHAP (Rituximab – Cisplatin – Cytarabine - Dexamethasone) chemotherapy treatment. We think that this treatment may be more effective when it is administered in an earlier stage of disease in asymptomatic patients.</p> Soykan Biçim İlhami Berber Mehmet Ali Erkurt İrfan Kuku Emin Kaya Yılmaz Bilgiç Ahmet Sarıcı Ahmet Kaya Emine Hidayet Ayşe Uysal ##submission.copyrightStatement## 2022-01-20 2022-01-20 1 5 Rituximab Induced Late Onset Neutropenia https://journalijr2h.com/index.php/IJR2H/article/view/30156 <p>Rituximab is a monoclonal antibody against CD20 a leucocyte cell marker expressed on normal and neoplastic B lymphocytes .Although first used for treatment of CD20 positive non-hodgkin’s lymphoma it’s use has expanded to include a varied spectrum of diseases mostly autoimmune disorders. Thus it is used in the treatment of autoimmune haemolytic anaemia, immune thrombocytopenia, rheumatoid arthritis, pemphigus vulgaris, vasculitis and many more autoimmune conditions.</p> <p>Rituximab is generally a well tolerated drug although many acute and delayed adverse effects are noted. Rituximab induced late onset neutropenia [LON] is a rare and life threatening adverse effect which needs to be suspected in patients presenting with neutropenia after four weeks of completing Rituximab therapy.</p> <p>We report a case of a 73year old man who presented with severe grade 4 neutropenia of 0.04x10<sup>9</sup>/L and life threatening sepsis 19 weeks after treatment of autoimmune haemolytic anaemia with four doses of Rituximab. He recovered with prompt initiation of G-CSF and made a complete recovery.</p> <p>LON is a delayed drug-induced reaction, which appears several months (usually 1 to 5 months) after cessation of rituximab treatment. With widespread use of Rituximab for autoimmune diseases in different medical disciplines it is important that these physicians are aware of and monitor patient’s post-Rituximab therapy for this delayed reaction.</p> K.

SCD is prevalent in Plasmodium falciparum endemic regions such as Nigeria. Thus, haematological parameter of SCD patients during malaria infection may be affected. Prophylaxis against malaria is therefore important in SCD patients, as antimalarial chemoprophylaxis has also been shown to be beneficial in SCD patients, reducing parasitaemia and anaemia, and the requirement for blood transfusion.</p> <p><strong>Aim: </strong>This study evaluated the haematological parameters of sickle cell disease patients on prophylactic antimalarial regimen within Port Harcourt, Rivers State, Nigeria.</p> <p><strong>Methods: </strong>This cross sectional study investigated 50 Sickle Cell Disease Patients attending different hospitals within Port Harcourt and 50 apparently healthy staffs and students of River State University who served as control. Three (3ml) of blood was collected aseptically from each participant and analyzed for complete blood count using Haematology auto-analyzer (Sysmex XN-550)</p> <p><strong>Results:</strong> The result show that male (51%) are more exposed to SCD in Port Harcourt than female (49%). There was a statistical significance in the Haemoglobin of Male (8.81±3.61) as compared to that of the female (11.62±3.77) (p=0.0097) while other parameters showed no statistical significance. The result showed a lower mean value for RBC, PCV, HB, MCV, MCH and MCHC of SCD patients on antimalarial regimen when compared to the control subjects. Higher mean value for WBC, Lymphocytes, Monocytes, and Eosinophils where statistically significant when compared with the control subjects. The result gotten emphasised the need for proper management of <em>P. falciparum</em> malaria in SCD.</p> <p><strong>Conclusion: </strong>This study discovered that sickle cell disease patients are more of the age range between 18-21 years (50%), this might be attributed to the fact that many of the SCD patients pass away before they get old due to the disorder. This study has also established that Sickle Cell Disease patients on prophylactic anti-malarial regimen have low haemoglobin, haematocrit, RBC, MCV, MCH, and MCHC, but increased WBC, lymphocytes, monocytes and eosinophils. Results from this study can help in the differential diagnosis of malaria infection in HbSS genotype based on haematological parameters in resource limited setting where sickle cell genotyping remains a challenge.</p> B.

No study has evaluated the interaction between these parameters in normal pregnancy.</p> <p><strong>Method: </strong>In this cross-sectional case-controlled study, baseline values for haematological and oxidative stress changes were evaluated in pregnant women attending an ante-natal clinic at selected private clinics in Bori. A total of 100 subjects (80 pregnant women and 20 non-pregnant women) were recruited for the study. Haematological and oxidative stress parameters were determined following standard protocols.</p> <p><strong>Results: </strong>The result of the study shows a significant increase in the mean values of white blood cells, neutrophils, monocytes and catalase among the pregnant women compared to non-pregnant control while the mean value of the eosinophils was found to decrease among the pregnant women compared to the non-pregnant control (p&lt;0.05). Neutrophils and catalase were significantly higher in the third trimester when compared with the non-pregnant control (p&lt;0.05). A significant negative correlation was observed between catalase and mean cell volume; superoxide dismutase significantly correlated negatively with haemoglobin concentration, packed cell volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cell and neutrophil counts. Glutathione significantly correlated negatively with neutrophils and monocytes while malondialdehyde significantly correlated with mean corpuscular hemoglobin concentration, total white blood cell, monocytes and eosinophil and basophile counts.</p> <p><strong>Conclusion: </strong>This study has demonstrated that there may be an association between oxidative stress and haematological parameters among pregnant women.</p> Jonathan Awajiomowa Bruno Chukwuemeka Chinko Kinikanwo Innocent Green ##submission.copyrightStatement## 2022-03-23 2022-03-23 30 39 Haematological Parameter and Indices in Hospitalized COVID 19 Positive Patients at Centre for Communicable Disease Control and Research (CCDCR), Federal Medical Centre, Asaba, Delta State, Nigeria https://journalijr2h.com/index.php/IJR2H/article/view/30161 <p><strong>Aims: </strong>To assess some haematological parameters and indices of hospitalized COVID-19 infected patients treated during the first wave of the pandemic in the Centre for Communicable Disease Control and Research (CCDCR) Federal Medical Centre Asaba, Delta State, Nigeria.</p> <p><strong>Study Design:</strong>&nbsp; Retrospective observational study.</p> <p><strong>Place and Duration of Study: </strong>Centre for Communicable Disease Control and Research, Federal Medical Centre, Asaba, Delta State, Nigeria., between May and September, 2020.</p> <p><strong>Methodology:</strong> Descriptive data was collected from the records of 52 patients who were hospitalized and treated at the CCDCR FMC Asaba, within the months of March to September, 2020 and 40 non Covid-19 subjects as control subjects. The patient samples that were previously collected and analyzed for haematological parameters (lymphocytes, neutrophil, eosinophil, basophil, monocytes, platelets count, mean cell volume (MCV), mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC), using an automated hematology analyzer. Data collected was analyzed using SPSS version 25 and P values less than <em>.05</em> were considered statistically significant.</p> <p><strong>Results:</strong>&nbsp; The outcome of statistical analysis showed that the mean levels of lymphocytes, MCH and MCHC were significantly lower (<em>P&lt;.05</em>) in COVID-19 positive subjects when compared with that of COVID-19 negative control group.&nbsp; Also, the mean level of total white cell count was significantly higher (<em>P&lt;.05</em>) in COVID-19 positive subjects when compared with that of the control group. There was no significant difference (<em>P&lt;.05</em>) in PCV, neutrophil, eosinophil, basophil, monocytes, platelet and MCV in the case study when compared with the control group. No correlation was observed between severity and PCV, total WBC, eosinophil, monocyte, platelet count, MCV and MCHC. Whereas, a weak negative correlation (<em>r = -.284, P=.041</em>) was observed between severity and neutrophil. On the other hand, a weak positive correlation between severity and MCH (<em>r=.303, P=.029</em>) as well as between severity and lymphocytes (<em>r=.0305, P=.029</em>) was observed. No significant difference (<em>P&gt;.05</em>) was observed in the outcome of haematological indices of COVID-19 positive subjects who are below fifty (50) years and those more than fifty (50) years of age. Also, no correlation was observed between haematological indices of the case subjects and their age. There is a significant difference in PCV (<em>P&lt;.05</em>) based on gender. However, other haematological indices did not differ based on gender.</p> <p><strong>Conclusion:</strong> Assessing the outcome of haematological indices in COVID 19 positive patients provides insight into the physiological state of these subjects which in turn aids management, treatment monitoring and prognostication. Further observational and experimental studies using larger sample size is hence recommended as this will give a more promising outlook of these indices in COVID 19 subjects.</p> Obu Sylvia Ifeoma Asiodu Anthony Uchenna Osiatuma Victor Azubuike Ojimba, Anastacia Okwudili Oburo Ngozichukwuka Andrew Iyasele Anthony Chukwuemeka Nnanna Tochi Praise Aigbokhaode Adesuwa Dibigbo-Ibeaji Ndudi Jisieike Obianuju Nkemjika Edet Samuel Eno Sadoh Odion Rosemary ##submission.copyrightStatement## 2022-03-28 2022-03-28 40 48 Frequencies of Rh Phenotypes and Probable Genotypes in RhD Negative Blood Donors in Oman: A Cross-sectional Study https://journalijr2h.com/index.php/IJR2H/article/view/30162 <p><strong>Aims:</strong> Knowledge of Rh phenotype frequencies guides in assessing the probability of Rh alloantibody formation and finding Rh-negative antigen donors.&nbsp; There is limited information on the RhCE phenotypes and probable genotype frequencies among D negative Omani population, hence this study was conducted to determine that and compared it with other populations.</p> <p><strong>Study Design:</strong> Cross-sectional study.</p> <p><strong>Place and Duration of Study: </strong>The study was conducted in Oman College of Health Sciences between July 2016 and April 2017.</p> <p><strong>Methodology:</strong> A total of 205 RhD negative blood samples were collected from Omani blood donors.&nbsp; Haemagglutination methods were used for Rh typing.

Despite the availability and known benefits of hydroxyurea, its use in low- and middle-income countries has been limited. The purpose of this study was to determine the proportion of children with SCA who receive HU at Rivers State University Teaching Hospital (RSUTH)’s paediatric haematology clinic, as well as to highlight the sociodemographic correlates of users.</p> <p>A descriptive cross-sectional study was done at the Paediatric Haematology clinic of RSUTH. The study participants were children with SCA attending the clinic. An interviewer administered semi-structured questionnaire was used to obtain socio-demographic data and information concerning the uptake of HU from caregivers of the subjects.</p> <p>This study enlisted the participation of 88 children. There were 38 (43.2%) males and 50 (56.8%) females, for a male to female ratio of 1:1.3. The subjects' ages ranged from 2 to 18 years. Approximately half of the study participants came from affluent families. In total, 26 (29.5 percent) of the study participants used hydroxyurea. The use of hydroxyurea was significantly higher in the upper socioeconomic class compared to the middle and lower classes. Its use was also significantly higher among those suffering from sickle cell disease complications.</p> <p>Hydroxyurea uptake remains low.

Platelet count below &lt;150,000×10<sup>3</sup>/mm<sup>3</sup> can pave way for the occurrence of thrombocytopenia. Occurrence of thrombocytopenia in pregnancy is one of the commonest abnormalities encountered, though benign in nature, resolves after birth. It is important to investigate for thrombocytopaenia due to the need for good haemostasis during pregnancy and the risk of neonatal hemorrhage. This study aimed at associating decrease in platelet count with gestational attendees in Rivers State University Teaching Hospital, Port Harcourt antenatal clinic.&nbsp;&nbsp; A total of 120 apparently healthy pregnant women were coopted into the study. Whole blood samples were drawn into EDTA anticoagulant bottles for analysis of platelet count using a Sysmex autoanalyser. Data was analysed using graph pad prism version 6.0. Revelations from the study showed the prevalence of thrombocytopaenia in pregnancy as 3.33%, the mean platelet count was (218.1±63.94). Mean platelet count did not differ in groups based on gestational age (first trimester - 202.6 ± 63.08, second trimester - 221.8 ± 60.54 , third trimester - 226.3±69.36, P=0.2784) and maternal age (&lt;21=204.5±34.65, 21-30=211.3±60.59, 31-40=219.2±62.12,&gt; 40=304.0±128.2 P=0.1083).

For the Rhesus blood group system, Rhesus positive had the highest percentage (94%) of GDM incidence.</p> <p><strong>Conclusion: </strong>Blood group might be a risk factor and it can be helpful for the evaluation of the disease, a study to investigate causal effect is advisable.</p> Arinze Favour Anyiam Emmanuel Ifeanyi Obeagu Ejeatuluchukwu Obi Pius Omoruyi Omosigho Emmanuel Anyachukwu Irondi Onyinye Cecilia Arinze-Anyiam Musa Kemi Asiyah ##submission.copyrightStatement## 2022-06-21 2022-06-21 113 121 Sickle Cell Anemia Contributes to Liver Abnormality https://journalijr2h.com/index.php/IJR2H/article/view/30173 <p><strong>Aim:</strong> This study sought to investigate the implication of sickle cell anemia on hepatic biomarkers.</p> <p><strong>Methodology: </strong>This is a case-control study which enrolled 60 sickle cell anemia patients (30 males and 30 females) in a stable state at the Obafemi Awolowo University Teaching Hospital in Ile-Ife, Osun State, Nigeria, as well as 60 healthy controls (30 males and 30 females). Each participant had five millilitres (5 mL) of venous blood taken and dispensed into a lithium heparin sample vial. Hepatic biomarkers were assessed using established procedures utilizing the blood sample.</p> <p><strong>Results:</strong> Hepatic indices were higher in sickle cell anemia patients than in control subjects, according to the findings of this study. It's worth noting that the effect of sickle cell anemia on liver parameters was stronger in male patients than in females. The activity of ALP in male sickle was 280 UI/L compared to the 198 UI/L in their female counterparts. Both values were significantly (p&lt;0.05) higher than those found in the control subjects. This was not different in other hepatic parameters investigated in this study.</p> <p><strong>Conclusion:</strong> The findings of this investigation revealed that sickle cell patients had significantly higher liver indices than control persons. This could indicate that its synthesis in the liver has been increased or metabolism was reduced sequel to sickle cell disease.</p> Chika L. Uche Abali O. Isaiah Edmund O. Ezirim Augustine I.

This study thus aimed at assessing the effect of insecticides inhalation on haemorrheological parameters using experimental animal model.</p> <p><strong>Materials and Methods:</strong> Sixteen adult male rabbits divided into four groups&nbsp; A, B, C and D. Group A,B and C were exposed to&nbsp; 20ml of pyrethroid insecticides containing 0.05% pralletrin and 0.15% cyfluthrin by inhalation for 10mins,20mins, and 30mins respectively. Group D serve as the control and was not exposed. Baseline study was done on all the animals before grouping for exposure.&nbsp; The pyrethroid insecticides was soaked in cotton wool (2.5g) in a container&nbsp; that was able to prevent the animal from ingesting it, which was placed inside&nbsp; the room A, B and&nbsp; C&nbsp; for 10mins,20mins and 30mins respectively. The rabbits were exposed for three weeks and sample were collected at the end of each week. Exposure was discontinued after day 21 and samples were collected again on day 28 and 35 respectively which is the fourth and fifth week. All the animals were monitored twice daily for clinical signs like jerky movement, skin scratching, licking of legs and other body parts.</p> <p><strong>Results:</strong> Data analysis revealed that there was significant effect of inhalation of&nbsp;&nbsp; insecticides on some haemorrheological parameters of rabbits at 10min, 20mins and 30mins of exposure. There was decreased in Plasma viscosity. But there was no significant effect on whole blood viscosity and plasma fibrinogen concentration.</p> <p><strong>Conclusion: </strong>The results from this study have shown that aerosol of these pyrethroid insecticides (pralletrin and cyfluthrin) has effect on haemorrheological parameters. It is thus recommended that one should avoid exposure to the aerosol of these insecticides during domestic, veterinary,agricultural or industrial use.</p> Emily Funmilayo Eyitayo Olusegun Taiwo Oke Emmanuel Ifeanyi Obeagu ##submission.copyrightStatement## 2022-08-04 2022-08-04 161 166 T-Cells Expression in HBV Infected Subjects in Port Harcourt, Rivers State, Nigeria https://journalijr2h.com/index.php/IJR2H/article/view/30179 <p>Hepatitis B virus infection is a potential life-threatening liver infection caused by hepatitis B virus capable of causing chronic infection and puts people at high risk of death from cirrhosis and liver cancer. This study was a comparative cross sectional study carried out on 260 hepatitis B patients and blood donors attending hepatitis B clinics and blood banks in Rivers State University Teaching Hospital, Military Hospital, and University of Port Harcourt Teaching Hospital. The aim of this study was to evaluate T-Cells expression in HBV Infected Subjects in Port Harcourt, Rivers state, Nigeria. HBV 5-parameter (panel) Rapid Test kit was used to assess HBV serological markers; BD Fascount automated machine was used in determining CD4, CD8, CD3, and CD4/CD8 ratio. SOP, GLP, External/Internal Quality Control were used accordingly and Quality Assurance ensued. All statistical tests conducted were 2-tailed, and probability value of &lt; 0.05 was used as the threshold for declaring statistical significance. Data management and statistical analyses were conducted using Statistical Analyses System SAS 9.4 (SAS Institute, Cary, North Carolina, USA). 84.2% participants were males, 15.8% females aged between 19 and 65 years, Mean ±SD age 30.57±9.70. Participants from 20 states, South-South, South-East, and other Geo-political Zones of Nigeria, resident in the cosmopolitan city of Port Harcourt were recruited for the study. Result obtained showed serological markers among test subjects as 77.3% HBsAg, 43.97% HBsAb, 48.94% HBcAg, 36.17% HBcAb, and 46.81% HBeAg. The serological markers were grouped into four (4) categories based on HBsAg positivity: (i) HBV positive 1 – ‘Occult HBV prior to treatment’ (naïve previously unknown HBV: HBsAg -ve, other HBV markers +ve) 7.8% positive, [n=11]; (ii) HBV positive 2 (HBsAg +ve, other HBV markers +ve) 73.76% positive, [n=104]; (iii) HBV positive 3 – ‘chronic or post treatment occult HBV’ (known HBV case now occult’: HBsAg -ve, other markers +ve) 14.18% positive, [n=20]; (iv) HBV positive 4 (HBsAg +ve, other markers -ve) 4.26% positive, [n=6]. CD3 and CD8 were significantly decreased in HBV infected subjects compared to healthy controls. CD4/CD8 ratio was significantly increased in HBV infected subjects compared to control group. CD4 count was decreased in HBV infected subjects than in healthy control though it was not statistically significant. CD3 and CD8 were significantly decreased (p&lt;0.0207 and P&lt;0.0041 respectively), in HBV positive subjects who were HBsAg negative but positive for other HBV serological markers, (HBV positive 3), when test subjects were compared by HBV panel assay. CD3 and CD4 showed very strong positive correlation (p&lt;0.0001) among test subjects. CD8 and CD4, DC8 and CD3 also showed strong positive correlations (p=0.0070 and p&lt;0.0001 respectively); CD4/CD8 ratio showed strong positive correlation with CD4, (p=0.0002). CD4, CD3, CD8, and CD4/CD8 ratio showed no statistically significant difference when compared by demographic indices including sex partner(s), marital status, and age group. CD4, CD3, CD8, and CD4/CD8 ratio may serve as prognostic markers in HBV infected subjects. Regular evaluation of these markers in HBV patients is advocated as it could be helpful for improved patient care/management. Periodic screening of some target population for HBV infection is recommended for our environment to check spread. Cost of diagnostic assays and treatment should be subsidized by government and capable cooperate organizations to help patients access regular and comprehensive health care.</p> Baribefe Banavule Daniel Koate Charles Teddy Adias Ebirien-Agana Samuel Bartimaeus Zacchaeus Awortu Jeremiah ##submission.copyrightStatement## 2022-08-06 2022-08-06 167 182 Distribution of ABO and Rhesus Blood Groups among COVID-19 Positive Subjects in Rivers State, Nigeria https://journalijr2h.com/index.php/IJR2H/article/view/30180 <p>Coronavirus-2019 (COVID-19) is a novel disease that is ravaging society today. It has been reported that individuals with some blood group antigens are more predisposed or susceptible to certain diseases. This study was carried out to determine the distribution of some blood group antigens among COVID-19-infected individuals. The study involved one hundred (100) subjects, comprising 75 males and 25 females, within the ages of 20 and 60 years, who were infected with COVID-19, and receiving treatment at the COVID-19 Isolation Centre. The bio-data of the subjects were obtained using a well-structured questionnaire. Five mililitres (5 ml) of blood collected asceptically from each of the subjects who gave informed consent were dispensed into K<sub>3</sub>EDTA bottles for the determination of the ABO and Rh blood groups. The bio-data show that 74% of the subjects were married while 26% were single. Also, 87% of the subjects had university degree or HND, 6% had OND while 7% had only secondary school education, indicating that majority of the subjects were educated. The results from the study showed that the distribution of ABO blood group among the subjects were 75% blood group O, 11% blood group A, 10% blood group B and 4% blood group AB. Also, 91% of the subjects were Rh positive while 9% were Rh negative. The results indicate that the blood group antigens found in the subjects were similar to the pattern reported in the population where the research was conducted. It is concluded that the prevalent blood group in this study was blood group O, while the most prevalent Rh group was Rh-D positive. It is recommended that blood groups be considered in the testing menus for the management of COVID-19 infection, since some subjects may have such blood group antigens that can predispose to the infection.</p> Onengiye Davies Serekara G.

Many children are hospitalized every year due to sequelae of this heterogeneous group of disorders to which pediatric hematologist take a variety of diagnostic and therapeutic approaches. AIHA is generally categorized as "warm" or "cold" based on the thermal reactivity of the autoantibodies and is further classified as primary (idiopathic) or secondary. Early recognition and diagnosis are very important for successful management and outcome of hemolytic anemia. The evaluation of suspected immune hemolytic anemia includes a thorough history, physical examination and laboratory workup assessing for evidence of acute hemolytic anemia, possible diagnosis of an acute event, to evaluate for concurrent causes and to rule out alternative causes.</p> <p>In this review article we will discuss the classification, diagnostic approach and general management of hemolytic anemia in children especially focusing on newly diagnosed autoimmune hemolytic anemia. Specific recommendations for difficult to diagnosed cases, definitions&nbsp; of response assessment and treatment i.e. dosage and tapering plan of&nbsp; steroid therapy; indications of rituximab, supportive therapy and second-line therapy are &nbsp;discussed.</p> Muhammad Matloob Alam ##submission.copyrightStatement## 2022-07-21 2022-07-21 150 160
