Abstract: BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the T helper (Th) to T cytotoxic (Tc) ratio in children suffering from type A hemophilia disease and to evaluate the correlation of this ratio with disease severity. MATERIAL AND METHOD: Two mls of EDTA anti coagulated whole blood was collected. Immunophenotyping of lymphocytes count was carried out by FACS analysis using a double CD4 and CD8 kit. The mean ± SD of absolute numbers of CD4 and CD8 lymphocytes/ml was calculated and the ratio of CD4/CD8 was evaluated by statistical method. …RESULTS: Among 80 type A hemophilia patients, 66 (82.5%) were male. The mean age was 15 ± 3.51 years. 12 (15%) of them were suffering from mild disease and 68 (85%) had sever disease. The CD4 /CD8 ratio was obtained between 0.45 and 1.44 with mean 1.79 ± 0.78. The correlation between this ration and disease severity was 0.019. CONCLUSION: The results showed that CD4/CD8 ratio has correlation with disease severity in type A hemophilia patients, however there was no association between this ratio and gender. Show more

Abstract: The number of circulating lymphocytes is altered in a number of diseases including either increase (lymphocytosis) or decrease (lymphocytopenia). Therefore, the assessment of total blood lymphocyte numbers and the relative distribution of lymphocyte subsets is a critical front-line tool in the clinical diagnosis of a number of diseases, including pediatric diseases and disorders. However, the interpretation of this data requires comparison of patient’s results to reliable reference values. Blood lymphocyte subpopulation numbers are also subject to genetic polymorphisms, immunogenic and environmental factors and vary greatly between populations. While the best practice reference values should be established within local representative populations …of healthy subjects, to date, Caucasian reference values are used in Morocco due to the absence of indigenous reference values. Potential differences in blood lymphocyte subpopulation reference values between Caucasian versus Moroccan populations can adversely affect the diagnosis of pediatric and childhood diseases and disorders such as primary immunodeficiency (PID) in Morocco. OBJECTIVE: The aim of this study was to establish the age-stratified normal reference values of blood lymphocyte subsets for the pediatric Moroccan population. METHODS: We measured the concentration of lymphocyte subpopulations by flow cytometry from 83 Moroccan healthy subjects stratified into 5 age groups of 0–1, 1–2, 2–6, 6–12 and > 12–18 (adult). RESULTS: The absolute and relative amounts of the main lymphocyte subsets of T-cells, B cells and Natural Killer (NK) cells were measured and compared to previously described reference values from Cameroonian, Turkish, American and Dutch populations. Additionally, we also observed an age-related decline in the absolute population sizes of lymphocyte subsets within our study group. Relative proportions of CD3 + CD4 + helper T lymphocytes decreased with increasing age and by 12 years-adult age, both proportions of CD3 + CD4 + helper T lymphocytes and CD3 + CD8 + cytotoxic T lymphocytes, as well as CD3 - CD19 + B lymphocytes were also decreased. Finally, we compared the median values and range of our Moroccan study group with that of published results from Cameroon, Turkey, USA and Netherlands and observed significant differences in median and mean values of absolute number and relative proportions of lymphocyte subsets especially at 0–1 years and 1–2 years age groups. Above age 12 years, the Moroccan values were lower. For NK cells, the Moroccan values are also lower. CONCLUSIONS: The results of this study have a significant impact in improving the threshold values of the references intervals routinely used in the diagnosis of paediatric diseases such as PIDs or mother-to-child transmitted HIV within the Moroccan population.

Abstract: BACKGROUND: The NCAM or CD56 antigen is a cell surface glycoprotein belonging to the immunoglobulin super-family involved in cell-cell and cell-matrix adhesion. NCAM is also over-expressed in many tumour types and is considered a tumour associated antigen, even if its role and biological mechanisms implicated in tumour progression and metastasis have not yet to be elucidated. In particular, it is quite well documented the role of the interaction between the NCAM protein and the fibroblast growth factor receptor-1 in metastasis and invasion, especially in the ovarian cancer progression. OBJECTIVE: Here we describe the isolation and preliminary …characterization of a novel human anti-NCAM single chain Fragment variable antibody able to specifically bind NCAM-expressing cells, including epithelial ovarian cancer cells. METHODS: The antibody was isolate by phage display selection and was characterized by ELISA, FACS analysis and SPR experiments. Interference in EOC migration was analyzed by scratch test. RESULTS: It binds a partially linear epitope lying in the membrane proximal region of two fibronectin-like domains with a dissociation constant of 3.43 × 10 - 8 M. Interestingly, it was shown to interfere with the NCAM-FGFR1 binding and to partially decrease migration of EOC cells. CONCLUSIONS: According to our knowledge, this is the first completely human antibody able to interfere with this newly individuated cancer mechanism. Show more

Abstract: Diets included high-fat (HFD) and high calories intake is correlated with greater risk of obesity and oxidative stress, which lead to increase the risk of related diseases such as cardiovascular and metabolic disease. In the present study, we have examined the hypolipidemic activity of Hypericum Scabrum extract on HFD fed rats. Fifty-four male Wistar rats divided into six groups: 1) control, 2) H. Scabrum extract (100 mg/kg gavage per day), 3) H. Scabrum extract (300 mg/kg), 4) HFD, 5) HFD and H. Scabrum extract (100 mg/kg), 6) HFD and H. Scabrum extract (300 mg/kg). The …groups were fed their diet and treatment for 3 months. Biochemical analysis showed elevated lipid serum profile in HFD rats compared to control group. H. Scabrum extract supplementation significantly ameliorated triglyceride, total cholesterol and LDL-cholesterol. H. Scabrum extract supplementation leading to increase HDL-cholesterol in HFD treated groups. This experiment showed that H. Scabrum extract decreased HFD complications and might be beneficial herbal drug for treatment of hyperlipidemia and obesity. Show more

Abstract: A novel Coronavirus (SARS-CoV-2) causing a cluster of respiratory infections (Coronavirus Disease 2019, COVID-19) first discovered in Wuhan, China, is responsible for a new illness that has been found to affect the lungs and airways of patients with associated symptoms of fever, cough and shortness of breath. In the light of few cases recorded so far in West Africa there is tendency for complacency. The region needs to make strategic plans based on available evidence to enable them effectively deal with this rapidly evolving pandemic. At this very moment countries like China, Italy, France, Spain, Iran, UK and …many others are witnessing sustained and intensive community transmission of this virus and increasing numbers of severe disease and death particularly among elderly patients with other comorbidities. The reality of the seriousness of this pandemic is alarming. Government of member states of ECOWAS need to prepare themselves by building capacity as well as implement evidenced-based steps to mitigate this rapidly evolving pandemic by testing persons presenting with symptoms (fever, cough and shortness of breath), isolating and treating those found positive, tracing and quarantining contacts, implementing social distancing as well as optimizing human and material endowment to allow healthcare workers offer safe quality clinical care for affected patients to prevent secondary infection among healthcare workers.
