Depistage De L’anemie En Urgence Au Chu Campus : Validation Du Degre De Concordance Entre Les Resultats De L’hemocue® Hb 301 Et Ceux Du Sysmex Xn-1000®

Introduction: Un dépistage fiable de l’anémié dans un contexte d’urgence grâce à un hémoglobinomètre de biologie délocalisée demeure un défis en Afrique. Le but de cette étude était d’évaluer le degré de concordance des résultats d’hémoglobinémie obtenus sur l’HemoCue® Hb 301 par rapport à ceux de l’analyseur Sysmex XN-1000®. Méthodes : Il s’est agi d’une étude rétrospective et transversale descriptive réalisée du 08 Mai 2017 au 23 Février 2018 au CHU Campus du Togo. La performance du Sysmex XN-1000®  a été confirmée grâce à l’évaluation de l’exactitude et de la fidélité de mesure. La performance de l’Hemocue® Hb 301 a été évaluée au moyen d’une régression linéaire et du diagramme de Bland et Altman vis-à-vis du Sysmex XN-1000®. Les critères de performances utilisés étaient ceux du Clinical Laboratory Improvement Amendments (CLIA) et de RICOS et al.  Résultats: Le niveau d’exactitude selon CLIA du Sysmex XN-1000® était de 100%. L’équation de la droite de régression était: Y (HemoCue® Hb 301) = 0,99x (Symex XN-1000®) + 0,54 g/dl. Les valeurs médianes des 100 échantillons sur le Sysmex et l’Hemocue étaient respectivement de 12,55 g/dl et 13,00 g/dl avec un biais médian de 3,58%, qui était inférieur au biais limite de ±7,0% (CLIA). Conclusion: Le Sysmex XN-1000® fournit des résultats d’hémoglobinémie interchangeables avec ceux de l’HemoCue® Hb 301, sans altération de la capacité diagnostique pour le patient. Il reste donc performant pour un quelconque dosage d’hémoglobinémie en urgence.  Introduction: Reliable anemia screening in an emergency setting, using a Point-of-care hemoglobinometer remains a challenge in Africa. The purpose of this study was to assess the degree of agreement between hemoglobin results obtained on the HemoCue® Hb 301 compared to those of the Sysmex XN-1000® Analyzer. Methods: This was a retrospective and cross-sectional descriptive study carried out from May 08 2017 to February 23, 2018 at the Campus teaching hospital of Togo. The performance of the Sysmex XN-1000® was confirmed by evaluating the measurement accuracy and precision. The performance of Hemocue® Hb 301 was assessed using linear regression and a Bland and Altman plot against Sysmex XN-1000®. The performance criteria used were those of Clinical Laboratory Improvement Amendments (CLIA) and RICOS et al. Results: The CLIA level of accuracy of the Sysmex XN-1000® was 100%. The equation for the regression line was: Y (HemoCue® Hb 301) = 0.99x (Symex XN-1000®) + 0.54 g / dl. The median values of the 100 samples on the Sysmex and Hemocue were 12.55 g / dl and 13.00 g / dl respectively, with a median bias of 3.58%, which was less than the borderline bias of ± 7.0 % of CLIA. Conclusion: The Sysmex XN-1000® provides interchangeable hemoglobin results with those of HemoCue® Hb 301, without altering the diagnostic ability for the patient. It therefore remains effective for any emergency dosage of hemoglobinemia

Antibacterial activity of alkaloids from Sida acuta

Sida acuta is a shrub indigenous to pantropical regions. The plant is widely used for its various pharmacological properties. Among compounds of pharmacological interest occurring in the plant, are indoloquinoline alkaloids. The aim of the present study was to investigate the antimicrobial activity of alkaloids of S. acuta from Burkina Faso. The alkaloids had a good antimicrobial activity against the test microorganisms. In the agar-well diffusion assay, highest inhibition zone diameters were recorded with Gram-positive bacteria. The broth microdilution assay gave minimal inhibitory concentration values ranging from 16 to 400 μg/ml and minimal bactericidal concentration values ranging from 80 to up to 400 μg/ml. The gas chromatography-mass spectrometry analysis of the same alkaloids led to the identification of cryptolepine and quindoline as the major components.Keywords: Cryptolepine, quindoline, indoloquinolines, antibacterial, Sida acut

Evaluation In Vitro De L’activité Antimicrobienne Des Extraits De Cassia Alata Linn. (Fabaceae)

Cassia alata (Linn) is a Togolese flora plant traditionally used in the treatment of skin diseases and diarrhea. The objective of this work was to evaluate the in vitro antimicrobial activity and to highlight certain phytochemical total and fractionated extracts of this plant harvested in southern Togo. These extracts were obtained from polar solvents such as water, ethanol and ethanol / water mixture in equal volume. Microbial strains used consisted of bacteria, Staphylococcus aureus, Escherichia coli and Klebsiella oxytoca and yeasts, Candida albicans and Candida krusei. The antimicrobial activity was evaluated by the liquid medium dilution method coupled to spread on solid medium. Highlighting chemical groups was made by a brief qualitative phytochemical analysis from staining tests. The results show that the ethanol leaves crude extract (EBE) was the most active of all the tested microbial strains. This extract completely inhibited the growth of S. aureus (MIC = 1.25mg/ ml.); very strongly C. albicans (PI = 94.34 % ) and C. krusei (PI = 90.67% ) and strongly E. coli ( PI = 80%) and K. oxytoca (PI=79.14 %). The other extracts were active in some organisms with percentage inhibition (PI) of between 68 and 97 %. The phytochemical screening of some extracts revealed the presence of flavonoïdes, tannins and saponins. C. alata seems to contain compounds that interact to inhibit the growth of yeasts and bacteria. These results in part to justify the use of this plant in the Togolese traditional medicines

Therapeutic potentials of ethanolic extract of leaves of Holarrhena floribunda (G. Don) Dur. And schinz (apocynaceae)

Background: Holarrhena floribunda is a plant of wide usage in the Togolese folk medicine. A previous ethnobotanical survey on the latex plants of the Maritime region of the country revealed that this plant was included in several recipes curing malaria and microbial infections. Therefore, this study aimed to seek for the effectiveness of the ethanolic extract of the plant in the treatment of these diseases.Methods: The antimicrobial test was performed using the agar well-diffusion and the NCCLS broth microdilution methods, while the in vivo antimalarial activity was evaluated following the four-day suppressive test of Peters. The acute toxic effects of the extract were monitored after a single oral dose (5,000 mg/kg body weight) administration in NMRI mice.Results: The results indicated that the ethanolic extract of leaves of H. floribunda was active on Staphylococcus aureus ATCC 29213 and clinical strains of Staphylococcus aureus, Salmonella typhi and Klebsiella pneumoniae with MICs ranging from 0.62 to 1.25 mg/mL. The extract also showed significant parasitaemia suppression in a dose-dependent manner. In the acute toxicity assay, the oral administration of the extract to the mice did not affect the relative weight of vital organs, and there were no signs of toxicity or death during the study period. The LD50 of the tested extract was found to be greater than 5,000 mg/kg, indicating its safety.Conclusion: This study demonstrates the antibacterial and antimalarial activities of leaves of H. floribunda and then, supports its medicinal use in the treatment of microbial infections.Keywords: Holarrhena floribunda, ethanolic extract, antibacterial, antimalarial, toxicit

Is a mass drug administration deworming programme for school-aged children enough to reduce the prevalence of soil-transmitted helminths and Schistosoma mansoni in adults: a cross-sectional study from Togo

BackgroundThe world health organization (WHO) introduced the mass drug administration (MDA) strategy in order to reduce the prevalence of soil-transmitted helminths (STHs) and Schistosoma mansoni in endemic areas. However, this strategy is not implemented in adult population in Togo. Thus, the question arose if the present MDA strategy contributes to the reduction of transmission rates. The present study aimed to monitor the prevalence of STHs and S. mansoni among adult’s, between 2017 and 2022, in the central region of Togo.MethodsTwo cross-sectional studies were conducted in six villages in the central region of Togo in 2017 and 2022. Stool samples were collected from adults over the age of 18 years. To assess STHs and S. mansoni infections, real-time multiplex qPCR and Kato-Katz techniques were performed. Data were analysed using SPSS software version 21 and GraphPad PRISM version 9.2.0. A p-value less than 0.05 was considered statistically significant.ResultsA total of 210 and 289 individuals were recruited in 2017 and 2022, respectively. We detected significant increase in the prevalence of STHs and S. mansoni from 7.61% to 24.56% (p=0.0008) and from 27.62% to 46.36% (p=0.0014) by Kato-Katz and RT-qPCR, respectively. The prevalence of Ancylostoma duodenale infection was the highest with an increase from 7.14% to 23.53% by Kato-Katz and 9.09% to 40.0% by RT-qPCR.ConclusionThe prevalence of STHs and S. mansoni increased in the adult population in the central region of Togo from 2017 to 2022, despite the implementation of MDA in school-aged children. Hence, there is an urgent need to include adult individuals and adapt the MDA programme in the central region of Togo
