Prevalence of alpha and beta haemolysin among blood group O donors in Bamenda, Cameroon.

Background: The occurrence of high titres of alpha (anti-A) and beta (anti-B) haemolysin immunoglobulin G antibodies in blood causes haemolysis during blood transfusion from a group O donor, commonly and inappropriately known as the 'universal blood donor', to a group A, B or AB recipient. Surprisingly, haemolysin testing is not routinely done during blood transfusion services in Bamenda, Cameroon. Objective: This study aimed to determine the prevalence of haemolysin among blood group 'O' donors at the Regional Hospital Bamenda Blood Bank, Bamenda, Cameroon. Methods: This was a cross-sectional descriptive study carried out between June and September 2020 at the Regional Hospital Bamenda Blood Bank, Bamenda, Cameroon. Blood group O donors who were free from transfusion-transmissible infections were selected systematically and serially and their serum tested for the presence of haemolysin. Haemolysin titres were determined, and titres ≥ 8 were considered significant. The associations between haemolysin prevalence and age group, gender and Rhesus D blood group were determined using the chi-square test. Results: The prevalence of haemolysin among the 480 study participants was 52.1% and significant haemolysin titres were detected in 18.5%. There was no association between haemolysin and gender, age group or the Rhesus D blood group. Conclusion: The prevalence of significant titres of haemolysin among participants in this study was high. There is the need to test for haemolysin in blood group O donors to prevent the potential risk to blood group A, B, and AB recipients and to provide safer blood for transfusion.

Evaluation of corrective actions of feedback from clinicians on Clinical Laboratory Services at Bamenda Regional Hospital Laboratory, Cameroon.

BACKGROUND: Customers' satisfaction is imperative for success. Clinical laboratories continuously strive to attain very high levels of customer satisfaction to serve their clients and maintain accreditation. The concept of customer satisfaction has not yet been asserted in most clinical laboratories in Cameroon. OBJECTIVES: Our objectives were to assess the satisfaction of clinicians with the laboratory services at the Bamenda Regional Hospital Laboratory, identify important challenges, corrective actions implemented and changes in satisfaction. METHODS: This retrospective study reviewed secondary data from clinician satisfaction survey records from March 2017 and November 2017. Challenges and implemented corrective actions were identified for assessed statements of dissatisfaction (dissatisfaction rates ≥ 20%) on the March 2017 survey. Satisfaction rates in March 2017 and November 2017 were compared. RESULTS: High levels of dissatisfaction were observed for general satisfaction, waiting time, communication, duty consciousness, specimen collection and approach on the March 2017 survey. The main challenges identified were: lack of respect for the expected length of the waiting time, poor attitude, inadequate information, staff shortage and inadequate supervision. Statistically significant reductions in rates of dissatisfaction were observed for general satisfaction, waiting time, communication, response to emergencies, issuing of results, specimen collection, approach and duty consciousness. CONCLUSION: Waiting time is a major cause of clinician dissatisfaction with laboratory services. The identification of clinicians' challenges and the effective implementation of corrective actions contribute to improvements in clinician satisfaction.

Time for Option B+? Prevalence and characteristics of HIV infection among attendees of 2 antenatal clinics in Buea, Cameroon.

As countries consider a wider use of triple antiretroviral therapy (ART) in pregnancy, which in recent World Health Organization guidelines is called Option B+, this study sought to explore the potential implications of adopting Option B+ by characterizing HIV infection in pregnant women attending 2 semiurban antenatal clinics in Cameroon. In a descriptive cross-sectional study, consenting women were screened for HIV; positive samples were confirmed using an enzyme-linked immunosorbent assay test, and CD4 levels and HIV viral loads were determined using flow cytometry and reverse transcription-polymerase chain reaction, respectively. The seroprevalence of HIV in the 407 pregnant women screened was 8.4% (95% confidence interval: 5.9%-11.5%). The majority (82.4%) of HIV-positive women had CD4 counts >350 cells/mm(3). A quarter (25%) had undetectable viral levels (<80 copies/mL). Adopting Option B+ in this setting would result in a 5-fold increase in the number of HIV-infected pregnant women being placed on lifelong triple ART.
