RESUMEN
To determine the prevalence of venous thromboembolism (VTE) among adult sickle cell disease (SCD) patients in Nigeria. METHODS: This was a multicentre retrospective study in which the medical records of adult SCD patients were reviewed. Information on demographics, steady-state haemogram, clinical phenotypes, duration of follow-up, history of VTE including risk factors and management was collected. RESULTS: Of the 509 SCD patients with a median (IQR) duration of follow-up of 2 years, 10 (2.0%) had VTE (9 DVT and 1 PE). Their median (IQR) age was 27 (22.8-30.3) years. Identifiable risk factors for VTE included positive family history (2, 20%) surgery, splenectomy, paraplegia and cancer (1, 10% each). No risk factor was identifiable in four persons. VTE had no significant association with age and gender. VTE was significantly associated with the following events: acute chest syndrome [p = .002, odds ratio (OR) 8, 95% CI 2.2-28.9], osteonecrosis [p = .012, OR 5.24, 95% CI, 1.45-18.91] and vaso-occlusive crisis [p = .035]. Also significantly associated with VTE were pulmonary hypertension [p = .001, OR 23.3, 95%CI 5.18-105.06] and stroke [p = .032, OR 9.35, 95%CI 0.87-53.25]. CONCLUSION: The prevalence of VTE among SCD patients in Nigeria is low. It is significantly associated with vaso-occlusive crisis, pulmonary hypertension and stroke.

Earlier reports suggest that cancer patients were twice more likely to contract severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In this report, we describe two patients with hematological malignancies seen at the peak of the first wave of the coronavirus disease 2019 pandemic. A 61-year-old man was referred to our urology unit he was diagnosed with nodular hyperplasia and multiple myeloma and commenced on bortezomib, thalidomide, and dexamethasone combination chemotherapy. He developed a cough and fever, with SPO2 86%, He was positive for SARS-CoV-2 and died a few days later. A 42-year-old man with Hodgkin lymphoma on treatment with Adriamycin, bleomycin, vincristine, and dacarbazine with positive SARS-CoV-2 exposure was diagnosed with pleural effusion at A/E. Three days postadmission, his condition worsened with low SPO2 despite intranasal oxygen. He died after testing positive for SARS-CoV-2. Patients with hematological malignancies tend to have a greater risk of SARS-COV-2 infection and severe disease due to immunosuppression from cancer and its treatment.
Résumé Des rapports antérieurs suggèrent que les patients atteints de cancer étaient deux fois plus susceptibles de contracter le coronavirus 2 du syndrome respiratoire aigu sévère (SARS-CoV-2) infection. Dans ce rapport, nous décrivons deux patients atteints d'hémopathies malignes vus au plus fort de la première vague de la maladie à coronavirus pandémie de 2019. Un homme de 61 ans a été référé à notre unité d'urologie. On lui a diagnostiqué une hyperplasie nodulaire et un myélome multiple. commencé une chimiothérapie combinée bortézomib, thalidomide et dexaméthasone. Il a développé une toux et de la fièvre, avec SPO2 86%, Il était positif pour le SRAS-CoV-2 et est décédé quelques jours plus tard. Un homme de 42 ans atteint d'un lymphome hodgkinien sous traitement par adriamycine, bléomycine, la vincristine et la dacarbazine avec une exposition positive au SRAS-CoV-2 ont reçu un diagnostic d'épanchement pleural à l'A/E. Trois jours après l'admission, son l'état s'est aggravé avec une faible SPO2 malgré l'oxygène intranasal. Il est décédé après avoir été testé positif au SRAS-CoV-2. Les patients atteints d'hématologie les tumeurs malignes ont tendance à avoir un risque plus élevé d'infection par le SRAS-COV-2 et de maladie grave en raison de l'immunosuppression du cancer et de son traitement.
