Immune thrombocytopaenic purpura in pregnancy: a case of near miss mortality in a Nigerian

Thrombocytopenia occurs in pregnancy like in the non-pregnant state and can be due to immune thrombocytopaenic purpura (ITP). The hyperoestrogenic state of pregnancy has been identified as a precipitating factor. This is a case report of a thirty year old Nigerian lady, who at a gestational age of 26 weeks developed ITP as a near miss mortality. Although, most literatures reported that the perinatal outcome is usually favourable in this condition, we report a case managed in our facility that had intrauterine death and non- remission until delivery; despite corticosteroid therapy and transfusion of eleven (11) units of blood. This report is relevant in a developing world where a rare condition almost caused a maternal death in spite of the high maternal mortality rates from other conditions. Baseline full blood count is advocated at booking to identify and monitor rare haematological disorders like this in pregnancy.

Determination of Normal and Variant Hemoglobin using Capillary Electrophoresis among Voluntary Blood Donors in North Central Nigeria: Implications on Blood Transfusion Services

Background: Voluntary non-remunerated blood donation is a strategy adopted by World Health Organization aimed at ensuring safety and adequacy of blood supply. Sub-Saharan Africa has a high prevalence of hemoglobin disorders and therefore needs to adopt stringent measures in donor selection to ensure safety for the recipient of blood transfusion. This study aimed to analyze normal and variant hemoglobin among voluntary blood donors. Methods: In this descriptive cross-sectional study, 100 prospective blood donors including 55 (55%) males and 45 (45%) females, aged 18–34 years were recruited. Capillary electrophoresis using the Minicap system was used for determining the hemoglobin variants in alkaline buffer (PH 9.4). Data analysis was done using SPSS version 20 and p-value < 0.05 was considered as the level of significance Results: The mean age of the participants was 22.23 ± 3.3 SD years. The proportion of participants with genotype AA was 67 (67%), those with AS were 17 (22 %), while those with AC were 11 (11 %). While Hb A ≥ 90% was noted in 67 (67%) blood donors, Hb S was seen in 22 (22%) and Hb A2 > 3.5% in 57 (57%). Hb F > 2% was observed in 3% of the studied participants Conclusion: Variant hemoglobin is common among blood donors and this should be taken into consideration whenever blood is being crossmatched for recipients of blood transfusion. Data from this study will be useful in raising awareness and genetic counseling. Keywords: prevalence, hemoglobin variants, capillary electrophoresi

SARS-CoV-2 variants-associated outbreaks of COVID-19 in a tertiary institution, North-Central Nigeria: Implications for epidemic control.

The COVID-19 global pandemic is being driven by evolving SARS-CoV-2 variants with consequential implications on virus transmissibility, host immunity, and disease severity. Continuous molecular and genomic surveillance of the SARS-CoV-2 variants is therefore necessary for public health interventions toward the management of the pandemic. This study is a retrospective analysis of COVID-19 cases reported in a Nigerian tertiary institution from July to December 2021. In total, 705 suspected COVID-19 cases that comprised 547 students and 158 non-students were investigated by real time PCR (RT-PCR); of which 372 (~52.8%) tested positive for COVID-19. Using a set of selection criteria, 74 (~19.9%) COVID-19 positive samples were selected for next generation sequencing. Data showed that there were two outbreaks of COVID-19 within the university community over the study period, during which more females (56.8%) tested positive than males (47.8%) (p<0.05). Clinical data together with phylogenetic analysis suggested community transmission of SARS-CoV-2 through mostly asymptomatic and/or pre-symptomatic individuals. Confirmed COVID-19 cases were mostly mild, however, SARS-CoV-2 delta (77%) and omicron (4.1%) variants were implicated as major drivers of respective waves of infections during the study period. This study highlights the importance of integrated surveillance of communicable disease during outbreaks
