Background: Sickle cell disease (SCD) is a prevalent inherited blood disorder. Globally, approximately 515 000 babies are born with SCD annually, with 75% of these births occurring in Africa. Integrating newborn screening (NBS) for SCD into primary healthcare structures, such as immunisation programmes, holds significant promise, with dried blood spots (DBS)-point-of-care technologies (POCT) like HaemoTypeSC offering cost-effective screening solutions.

Article Synopsis
  • Pregnancy in women with sickle cell disease (SCD) poses significant risks, particularly due to red blood cell (RBC) alloimmunisation, which complicates transfusion options.
  • A study conducted in Bamako between August 2022 and January 2023 involved 95 pregnant women with SCD, revealing that 62% had prior blood transfusions and a 14% prevalence of RBC alloantibodies, with anti-E and pan-agglutinins being the most common.
  • The findings indicate that history of miscarriage, blood transfusions, and the number of pregnancies are key risk factors, highlighting the need for improved screening and collaboration among healthcare providers to better manage care for SCD patients during pregnancy.

The Coronavirus disease 2019 pandemic is a real crisis that has exposed the unpreparedness of many healthcare systems worldwide. Several underlying health conditions have been identified as risk factors, including sickle cell disease, a chronic illness with various complications that can increase the risk of severe COVID-19 infection. Our study aimed to investigate the profile of sickle cell patients diagnosed with COVID-19 and explore any potential relationship between these two conditions.

Sickle cell disease (SCD) is a life-threatening disease requiring reliable early diagnosis. We assessed the acceptability and diagnostic performances of two rapid diagnostic tests (RDTs) to identify SCD (HbSS, HbSC, HbS/β-thalassaemia) or SCD carrier (HbS/HbC) in a pilot SCD newborn screening (NBS) strategy in Mali. All consenting delivering women were offered SCD NBS using cord blood sampling on two RDTs (SickleScan® and HemotypeSC®) compared to the high-performance liquid chromatography (HPLC) gold standard to detect SCD states.

Risk factors associated with complications occurring in sickle cell disease are not fully elucidated. The purpose of this study was to evaluate the existence of an association between the clinical severity of sickle cell disease and platelet count in the steady state phase in patients with sickle cell disease followed up at the Center for Research and Control of Sickle Cell Disease in Bamako, Mali. We conducted a retrospective review of 40 medical records of patients aged 5 to 42 years with sickle cell disease at the Center for Research and Control of Sickle Cell Disease in Bamako, Mali.

In this review, we report a case of a bone's metastatic breast cancer in Malian patient treated by chemotherapy in whom SRAS-COV-2's diagnosis was made 9days after the onset gastrointestinal symptoms. Patient quickly died before any COVID-19's treatment. According to the poor outcomes of cancer patients with COVID-19, authors emphasize to an intensive attention to such patients in order to find the best therapeutic balance between the two pathologies during this pandemic.

The metabolomic profile of vaso-occlusive crisis, compared to the basal state of sickle cell disease, has never been reported to our knowledge. Using a standardized targeted metabolomic approach, performed on plasma and erythrocyte fractions, we compared these two states of the disease in the same group of 40 patients. Among the 188 metabolites analyzed, 153 were accurately measured in plasma and 143 in red blood cells.

Objective: Few studies have been conducted on breast cancer in Sub-Saharan Africa and their results have been suspected to be impaired by artefacts. This prospective study was designed to determine tumor and patient characteristics in Mali with control of each methodological step. These data are necessary to define breast cancer treatment guidelines in this country.
