Lymphocytic Lymphoma Transforming into Hodgkin Lymphoma in Sub-Saharan Africa: Case Report and Literature Review.

The Hodgkin variant Richter syndrome (HvRS) is an infrequent complication occurring in 1% of lymphocytic lymphoma/chronic lymphocytic leukemia patients. We report a case of HvRS diagnosed in Sub-Saharan Africa. A 63-year-old patient was consulted for the investigation of an abdominal mass that had been evolving for 5 years prior to admission.

Morbidity and Mortality Associated with COVID-19 and Acute Chest Syndrome in Sickle Cell Disease Patients.

SUMMARYCOVID-19 infection has emerged as a comorbidity that can significantly increase morbidity and mortality in sickle cell patients with ACS (acute thoracic/chest syndrome). The aim of our study was to assess COVID-19-related morbidity and mortality in sickle cell patients with ACS. This was a retrospective, descriptive study of patient records followed over a 36-month period from January 2020 to December 2022.

A Case of Rosai-Dorfman Disease Successfully Treated by Corticotherapy.

Rosai-Dorfman disease (RDD) is a benign histiocytic proliferation that results in nodal and extranodal involvements. It is a rare disease, with fewer than 1,000 cases reported in the literature, which explains its lack of knowledge by physicians and the lack of codified therapeutic strategies. We report the case of an 8-year-old girl who presented a rapidly progressive cervical lymph node mass; the diagnosis of RDD was made based on histology and immunohistochemistry.

Homozygous Sickle Cell Disease after Age of 40: Follow-Up of a Cohort of 209 Patients in Senegal, West Africa.

Objectives: The aim of this study was to describe the morbidity and mortality of homozygous sickle cell disease after the age of 40.

Methods: This was a cohort study of 209 patients followed from 1994 to 2022. All hemoglobin electrophoresis-confirmed SS sickle cell patients over 40 years were included.

Evaluation of knowledge of priapism in sickle cell patients in Senegal.

Purpose: Erectile dysfunction is a dreadful complication of priapism especially with delay in diagnosis and management. The lack of awareness of priapism as a vaso-occlusive complication of sickle cell disease (SCD) is more concerning. The objective of this study was to evaluate the burden of priapism in adult Senegalese males adults with sickle cell disease.

Homozygous sickle cell disease related mortality in Senegal (2011-2020).

Homozygous sickle cell disease (HSCD) is characterized by multiorgan morbidity and an increased risk of early death. We aim to describe the mortality rate, causes, and risk factors of death in HSCD between 2011 and 2020. We conducted a retrospective study with a duration of 10 years in the cohort of 2348 HSCD patients.

Life-threatening bleeding in patients with hemophilia (PWH): a 10-year cohort study in Dakar, Senegal.

Objective: The aim of this study was to assess incidence, risk factors, treatment and outcome of LTB in Senegalese people with hemophilia (PWH).

Methods: We analyzed the characteristics of LTB in a cohort of 274 PWH after 10 years of follow-up.

Results: We included 274 patients (241 HA and 33 HB).

Transfusion Practice, Post-Transfusion Complications and Risk Factors in Sickle Cell Disease in Senegal, West Africa.

Context And Objectives: Blood transfusions (BT) remain a mainstay of therapy for patients with sickle cell disease (SCD) but pose significant clinical challenges. We aim to assess infectious markers, red cell alloimmunization, and iron overload secondary to BT in SCD patients.

Materials And Methods: This case-control study included 253 SCD (153 SCD-transfused and 100 SCD non-transfused).

Chronic viral hepatitis, HIV infection and Non-Hodgkin lymphomas in West Africa, a case-control study.

Non-Hodgkin lymphomas (NHL) are underestimated causes of cancer in West Africa where chronic viral hepatitis and HIV are endemic. While the association with HIV infection has already been characterized, limited information is available on the association between chronic viral hepatitis and NHL in sub-Saharan Africa. A case-control study was conducted in referral hospitals of Abidjan (Cote d'Ivoire) and Dakar (Senegal).

Challenges in the management of sickle cell disease during pregnancy in Senegal, West Africa.

Objectives: The aim of this study was to evaluate the maternal and fetal complications in pregnant patients with sickle cell disease (SCD) and find risk factors of stillbirth.

Method: We conducted a prospective study in pregnant women with SCD. Demographic characteristics, maternal and fetal morbi-mortality, and outcome of pregnancies were described.

Bleeding risk assessment in hemophilia A carriers from Dakar, Senegal.

: Hemophilia A carriers have an abnormal X chromosome with a molecular abnormality of FVIII gene. These carriers, long considered to be free of bleeding risk, could have the same symptoms as mild hemophiliacs. This study aim to assess bleeding risk of hemophilia A carriers monitored at the Clinical Hematology Department of Dakar.

Circumcision in hemophilia using low quantity of factor concentrates: experience from Dakar, Senegal.

Background: Circumcision in hemophiliacs is a delicate surgery because of bleeding risks that could be avoided by adequate substitution of coagulation factor. This practice is very challenging in countries where anti hemophilic treatment is inaccessible. The study aimed to evaluate a circumcision protocol in hemophilia A using low quantities of factor concentrates.

Pattern of chronic myeloid leukemia in the imatinib era in a Sub-Saharan African setting.

Chronic myeloid leukemia (CML) is an orphan disease in Africa because of the inaccessibility to specific treatment and the high cost of diagnosis and monitoring patients. The aim of this study was to report CML treatment response in a developing country in the tyrosine kinase inhibitor era. We conducted a longitudinal study of our cohort of CML patients.
