Background: The Democratic Republic of the Congo (DRC) is the third most affected country worldwide by sickle cell disease (SCD). However, this disease is still orphaned in the country; large-scale control actions are rare, and little is known about its management. Objective: To assess current practices in the management of SCD in Kisangani, DRC. Methods: This cross-sectional study was conducted in six health facilities in Kisangani. It involved 198 presumed sickle cell patients attending the above health facilities. The study focused on the sociodemographic and clinical data of the participants, obtained through a clinical examination and their medical records. Diagnostic confirmation of SCD was made by high-performance liquid chromatography coupled to mass spectrometry. Data were analyzed using SPSS 20.0. Results: The diagnosis of SCD was confirmed in 194 (98.0%; 95% CI: 94.9-99.2) participants, while it was not confirmed in 4 (2.0%; 95% CI: 0.8-5.1) participants. The diagnosis was mainly made by the Emmel test (42.9%). 45.8% of participants had previously been transfused with the blood of their parents. Folic acid was taken by 48.5% of participants and the previous intake of hydroxyurea was reported in 5.1% of participants. The participants vaccinated against Pneumococcus were 13.6% and against Haemophilus influenzae type b 28.3%. Penicillin prophylaxis was received by only 1.5% and malaria prophylaxis by 11.6% of participants. Conclusion: Standard-care practices for SCD patients in Kisangani are insufficient. The Congolese government should regard this disease as a health priority and consider actions to improve its management.
Background: Education is needed as an action to reduce morbidity and mortality from sickle cell disease (SCD), an important but largely neglected risk to child survival in most African countries as Democratic Republic of Congo (DRC). Objective: To assess the knowledge of Kisangani University students in DRC regarding SCD. Methods: In this non-experimental, cross-sectional study, a validated questionnaire was used to assess the knowledge of 2 112 Kisangani University students in DRC and data were analyzed using SPSS version 20. Results: Most participants, 92.9% (95% confidence interval [CI]: 91.7-93.9) were knowledgeable about SCD and have heard about it through schools and/or universities (46.3%), followed by family (34.5%) and health-care workers (23.5%). Nine hundred and seventy-three (46.1%; 95% CI: 44.0-48.2) and 37.9% (95% CI: 35.9-40.0) subjects indicated, respectively, that SCD is an acquired and hereditary disease. Moreover, 53.6% (95% CI: 51.5-55.7) said that the diagnosis of SCD is made by blood tests, while 46.2% (95% CI: 44.1-48.3) talked about urine tests. About 85.6% were unaware of the risk of children becoming sickle cell patients when both parents have SCD. To prevent SCD, premarital screening was cited by only 7.7% (95% CI: 6.6-8.9) of subjects and no measure was known by 25.4% (95% CI: 23.6-27.3). However, 79.6% (95% CI: 77.8-81.3) approved the need of premarital screening of SCD. Discussion: This study highlighted that the Kisangani university students' knowledge regarding SCD is poor and needs to be improved; education programs and motivational campaigns to be enhanced.
Objectives: To determine the prevalence of red blood cell (RBC) alloimmunisation and alloantibody specificity in sickle cell disease (SCD) patients in Kisangani, Democratic Republic of Congo (DRC) in comparison with those followed at the Centre Hospitalier Régional (CHR) de la Citadelle of Liège (Belgium).Background: Data regarding RBC alloimmunisation (immune response of the organism to foreign erythrocyte antigens, antigens that lack on its own RBC) in SCD patients are scarce in sub-Saharan Africa.Methods: We conducted a multi-site-based cross-sectional study among 125 SCD patients at Kisangani and 136 at the CHR de la Citadelle of Liège. The diagnosis of SCD was confirmed by high-performance liquid chromatography. Alloantibodies were screened using the agglutination technique on gel cards and their specificity determined using 11 and/or 16 cell panels. Statistical analyses were carried out using SPSS.Results: The prevalence of RBC alloimmunisation was 9.6% among SCD patients in Kisangani versus 22.8% in those of Liège. At Kisangani as well as at Liège, the median age of alloimmunised patients was higher than that of non-alloimmunised patients, 15.5 years (IQR:4.8-19.8) and 24 years (IQR:14-31) versus 10 years (IQR: 6.5-17) and 17 years (IQR:12-24), respectively. The median number of blood units was higher in both Kisangani and Liège immunised patients compared to non-immunised patients, 8 (IQR:5-11) versus 5 (IQR:3-13) and 41(IQR:6-93) versus 6.5(3-37) respectively. At Kisangani (N = 14), the most frequent antibodies were anti-D (28.6%) and anti-C versus anti-E (13.6%), anti-S (13.6%) and anti-Lea (11.4%) at Liège (N = 44).Conclusions: These findings stated that alloimmunisation is a common complication in SCD patients in the DRC. In the resource-limited setting of this country, blood transfusion with minimal ABO, D, C and E antigen matching in addition to the use of compatibility test could significantly reduce the incidence of this complication.
