IntroductionNumerous biological parameters are physiologically modified during normal pregnancy, in particular hematology. The knowledge of these modifications of the maternal body by biologists and clinicians allows the screening of possible anomalies. In Morocco, the reference values of the complete blood count test for pregnant woman are missing, as are those specific to different trimesters of pregnancy. The aim of this study is to look for the reference values for healthy pregnant women of the Northwest region of Morocco, to compare them to those of non-pregnant women (control) and to those of the literature.MethodsBlood samples were taken voluntarily from 3898 healthy pregnant women from 18 to 46 years old who presented themselves at the center of health Kalaa and at the service of gynecology obstetrics of the Provincial Hospital Center of M'diq (Morocco), for prenatal care. To establish the reference intervals of the CBC for non-pregnant women, a control group was constituted by 7035 healthy women from 18 to 50 years old selected according to the Moroccan law of blood donation. The CBC was measured on a Sysmex KX21N® analyzer. For each sample a systematic blood smear was done to determine the leukocyte differential.ResultsA statistically significant difference between the pregnant women and control group was noted (p < 0.05) for all the hematological parameters: red blood cells, hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, leukocytes, neutrophils, basophils, eosinophils, lymphocytes, monocytes, platelets and mean platelet volume. So, the comparison of the averages established between the first, second and third trimester of pregnancy showed the existence of a significant variation with regard to all the parameters of the CBC test looked for (p < 0.001).ConclusionThe present study provides additional baseline data for basic hematological parameters in healthy pregnant Moroccan women and concluded that pregnancy in women has the tendency to alter some hematological indices. For these reasons, there is an interest to take these modifications into account for optimal maternal and fetal medical care.
La drépanocytose homozygote, fait partie des hémoglobinopathies les plus fréquentes au Maroc. La drépanocytose est caractérisée par une grande variabilité d’expressions clinique et biologique qui dépendent des facteurs génétiques modulateurs et environnementaux. Elle se manifeste par une anémie régénérative de gravité très variable selon les individus. L’évolution spontanée en l’absence de traitement est le décès précoce. La drépanocytose est caractérisée par une grande variabilité d’expression clinique et biologique qui dépend des facteurs génétiques et environnementaux. Un tableau clinique sévère marqué par une fréquence de transfusion élevée et précoce, des complications infectieuses graves et une mortalité précoce. Un état inflammatoire constant caractérisé par des protéines inflammatoires élevées et état nutritionnel compromis. L’objectif est de déterminer le profil des paramètres hématologiques du drépanocytaire homozygote (SS) marocain au cours des stades stationnaires. Nous avons fait une étude descriptive transversale de 87 patients drépanocytaires (SS). Nous avons réalisé une étude biologique comportant: l’hémogramme avec étude morphologique des globules rouges en coloration MGG et numération automatique des réticulocytes. Les électrophorèses de l’hémoglobine à pH alcalin (8.8) sur gel d’agarose avec intégration densitométrique. L’âge moyen est de 13.22 ans ± 16.36 avec un sex- ratio (H/F) de 1.175 et des extrêmes allant de 0.6 à 36 ans. La répercussion de l’anémie sur le plan biologique, est intense chez 88.5% des patients, 67.8% ont une anémie normocytaire contre 29.9% présentant une microcytose, et 2.3% qui présentaient une macrocytose. Le degré d’anisocytose est lié au degré d’anémie, très évocatrice chez les drépanocytaires homozygotes S/S (95,4%). Une réticulocytose était observée chez nos patients (81,6%) et 52.9% présentaient une thrombocytose. Une leucocytose était observée chez 64.4% des patients et 80.5% ont présenté une neutropénie. Les paramètres de l’hémogramme serviront de base de comparaison lors des crises et permettront d’évaluer l’efficacité de la prise en charge par le clinicien. Les valeurs élevées des globules blancs, plaquettes et CCHM semblent déterminants dans l’expression sévère de la drépanocytose au Maroc. Le profil hématologique du drépanocytaire marocain montre des données semblables à celles rapportées en littérature chez ceux de l’Afrique centrale, avec une leucocytose. Les résultats de notre étude suggèrent que, la drépanocytose est un problème de santé le plus fréquent chez les marocains et que nos résultats sont comparables à ceux décrits dans le syndrome drépanocytaire majeur.
Improvement of oat lines via introgression is an important process for food biochemical functionality. This work aims to evaluate the protective effect of phenolic compounds from hybrid Oat line (F11-5) and its parent (Amlal) on hyperglycemia-induced oxidative stress and to establish the possible mechanisms of antidiabetic activity by digestive enzyme inhibition. Eight phenolic acids were quantified in our samples including ferulic, p-hydroxybenzoic, caffeic, salicylic, syringic, sinapic, p-coumaric and chlorogenic acids. The Oat extract (2000 mg/kg) ameliorated the glucose tolerance, decreased Fasting Blood Glucose (FBG) and oxidative stress markers, including Superoxide dismutase (SOD), Catalase (CAT), Glutathione peroxidase (GPx), Glutathione (GSH) and Malondialdehyde (MDA) in rat liver and kidney. Furthermore, Metformin and Oat intake prevented anxiety, hypercholesterolemia and atherosclerosis in diabetic rats. In vivo anti-hyperglycemic effect of Oat extracts has been confirmed by their inhibitory activities on α-amylase (723.91 μg/mL and 1027.14 μg/mL) and α-glucosidase (1548.12 μg/mL & 1803.52 μg/mL) enzymes by mean of a mixed inhibition.
IntroductionAmong the most useful biological examinations in common medical practice, blood count is the most prescribed. The reference intervals of the hematological parameters of this examination are of major importance for clinical orientations and therapeutic decisions. In Morocco, the reference values used by the laboratories of medical biology and used by doctors are ones collected from Caucasian and European individuals. These values could be different in the Moroccan population. Besides, reference intervals of the blood count specific to the various Moroccan regions are missing. We decided to determine the reference intervals from a population of healthy adults of the Tangier-Tetouan region by following the procedures recommended by the IFCC-CLSI guidelines in 2008 and comparing them to those of the literature.MethodsBlood samples were taken from 15840 adult volunteers (8402 men from 18 to 55 years old and 7438 women from 18 to 50 years old) from the regional transfusion center of Tangier and Tetouan during a period between November 2014 and May 2016. The complete blood count was measured by the Sysmex KX21N® analyzer. For each sample a systematic blood smear was done to determine the leukocyte differential. The data analysis was made by the software SPSS 20.0 by using percentiles 2.5th and 97.5th.ResultsA significant difference between both sexes was noted (p<0,001) for all the hematological parameters (red blood cells, hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, leukocytes, neutrophils, basophils, eosinophils, monocytes, platelets and mean platelet volume) except for the numeration of lymphocytes (p = 0.552). The values of this study were compared with those reported in Arabic, Caucasian and African populations. Said comparisons showed the existence of significant differences.ConclusionThis study tries to accentuate the necessity of proceeding with the establishment of reference intervals specific to the blood count of the Moroccan population to avoid errors of diagnosis, allow clinicians to interpret with greater specificity the hematological examinations and to improve the quality of medical care distributed to patients.
