Prevalence of Dyslipidemia among Patients Received at the Biochemistry Unit of the Charles de Gaulle Pediatric University Hospital in Ouagadougou

Introduction: Cardiovascular disease represents a major public health burden worldwide. Research and management of risk factors contribute to the prevention of these diseases. The aim of this study was to assess the prevalence of dyslipidemia in the biochemistry unit of the Charles De Gaulle Pediatric University Hospital (CHUP-CDG) in Ouagadougou. Material and Methods: This was a descriptive and analytical cross-sectional study, with retrospective data collection from January 1, 2020 to December 31, 2022. Patients of all ages who performed a lipid panel in the CHUP-CDG biochemistry unit during the study period have been included. Results: A total of 2872 patients have been included. The mean age of the study population was 27.72 ± 19.51 years and the M/F sex ratio was 0.81. Among the patients, 22.84% had at least one dyslipidemia. The prevalences of hypercholesterolemia, hypo-HDL cholesterolemia and hyper-LDL cholesterolemia were 11.57%, 49.19% and 57.50% respectively. Hypertriglyceridemia and mixed hyperlipidemia were present in 9.04% and 2.08% of patients. Hypercholesterolemia was significantly more frequent in the female sex (p = 0.0077);hyper-LDL cholesterolemia (p = 0.0255) and mixed hyperlipidemia (p Conclusion: The relatively high prevalence of dyslipidemia in the study indicates a worrying situation. It would therefore appear essential to extend the search for risk factors nationwide, particularly those that can be modified, in order to reduce morbidity and mortality linked to cardiovascular disease.

Evolution of Biochemical, Hematological, Inflammatory and Immunological Markers among Person Living with HIV-1 on ART in Burkina Faso

In Human immunodeficiency virus infected (HIV+) patients, deregulation of regulatory T (Treg) cells can be deleterious for the development of an efficient anti-HIV specific immune response with an inappropriate immune activation despite anti-retroviral therapy (ART). In addition, infection and ART have the potential to cause hematological and biochemical abnormalities that can lead to the discontinuation of ART. The aim of this study was to assess hematological, biochemical and immunological abnormalities in HIV+ patients’ naïve to ART and 6 months after ART initiation. In a cross-sectional study, 11 HIV+ patients and 09 healthy individuals (control group) were voluntarily recruited. At inclusion, blood samples were taken before administration of ART. All hematological, biochemical, immunological parameters and viral load were measured and assessed at inclusion (M0) and three and/or six months later (M3, M6). Higher level of white blood cells and CD4+ T lymphocytes (p = 0.032, 0.038 respectively) were observed in HIV+ patients. ART also had significantly effect on the level of red blood cells (p = 0.04) and Hb (p = 0.015). The inflammatory markers, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) that were significantly increased by HIV infection, tended to decrease for ESR and revert to levels similar to those of control for CRP. Analysis of CD4+CD25+ cells and CD4+Foxp3+CD25+ showed significantly elevated levels of activated form of all CD4+ cells and Treg cells. Interestingly, six months after initiation of ART, the average percentage of CD4+CD25+ was not significantly different from control group (p = 0.382). Our study provides information about the evolution of the activated form of all CD4 cells and Treg cells and points out the necessity to monitor hematological and biochemical parameters in order to detect and prevent toxicity, improve the quality of life and reduce the risk of mortality.

Identification of Bacteria Strains Isolated in Urinary Tract Infections and Their Antibiotic Susceptibility at the National Public Health Laboratory, Ouagadougou

Background: Urinary tract infections are still a real public health concern. The aim of this study was to identify the bacteria strains involved in urinary tract infections and to determine their antibiotic resistance profiles. Methods: Two kinds of studies were performed. The retrospective study was carried out for 2 years (from January 2018 to December 2019), and the prospective study was extended over a period of 6 months (from January to June 2020). Isolation and identification of bacteria strains were performed using conventional microbiology techniques. The strains’ resistance profiles were determined by the diffusion method on Mueller-Hinton according to the criteria of EUCAST- 2015. Fourteen (14) antibiotic discs were used depending on the isolated germ. Results: A total of 187 bacterial strains were isolated from 82 men and 105 women. Among the germs identified, 77.54% were Enterobacteriaceae and 13.36% were cocci strains. Non-fermentative gram-negative bacilli accounted for 9.08% of the isolated bacteria. The results showed that the majority of Enterobacteriaceae strains were resistant to beta-lactams: 100% to amoxicillin, 98.75% to amoxicillin + clavulanic acid, 41.76% to ceftriaxone, and 43.14% to ceftazidime. These findings were obtained with fluoroquinolones and aminoglycosides: 50.09% with ciprofloxacin, 54.04% with norfloxacin, and 22.58% with amikacin. 8.75% of the Enterobacteriaceae strains tested were resistant to imipenem. The same trends were observed with non-fer- mentative bacteria. As for the gram-positive bacteria isolated during our study, 13.33% were resistant to vancomycin, 21.05% to gentamicin, 94.12% to penicillin G, 88.89% to ampicillin, 77.78% to cefotaxime, 63.63% to kanamycin, and 52.63% to erythromycin. Conclusion: This study revealed, as in other studies, that Enterobacteriaceae strains remain the most incriminated bacteria strains in urinary tract infections, with a strong resistance to antibiotics. It is important that actions be taken to reduce the incidence of urinary tract infections and mitigate the spread of resistant bacteria.

Abnormalities of Serum Protein Fractions in Hemodialysis Patients with Chronic Renal Failure at Ouagadougou, Burkina Faso

Introduction: The main objective of this study was to investigate abnormalities of serum protein fractions in hemodialysis patients with chronic renal failure (CRF) in Ouagadougou, Burkina Faso. Methods: This was a descriptive cross-sectional study of 48 hemodialysis patients with chronic renal failure (CRF) recruited at the Yalgado Ouedraogo Teaching Hospital (YO-TH), and 48 controls declared fit to donate blood by the Regional Blood Transfusion Center (RBTC) of Ouagadougou. Urea, creatinine, uric acid, and serum proteins were measured on the ARCHITECT C4000 equipment (ABOTT®), while the separating of the different protein fractions was performed on the Helena SAS 3 & 4 automated system. Results: A total of 96 individuals were included in the study. Protein levels were on average higher in controls (75.19 ± 6.56 g/L) than in hemodialysis patients (71.44 ± 12.33 g/L). Low blood albumin was significantly associated with the CRF hemodialysis groups compared to controls (p Conclusion: Serum protein electrophoresis is rapidly feasible and low cost. In hemodialysis CKD patients, it can be used to guide therapeutic management and predict morbidity and mortality related to variations in the various protein fractions.
