It was exponentially boosted in low and middle income countries. Bacterial resistance to ATBs is now one of the most serious threats to global health and is daily faced by all healthcare actors. In 2016, the World Health Organization (WHO) published an action plan to combat ATBs resistance, encouraging member states to develop their own national action plans. The objective of our study is to provide a state of the art reflecting the consumption patterns of ATBs in pharmacy stores. Material and methods: Our descriptive study lasted for 3 months and included all consenting patients presenting to a pharmacy of the city of Rabat (Morocco) for antibiotic treatment either on medical prescription, pharmaceutical advice or self-medication. The total number of included patients was 150. Results: Among 166 ATBs dispensed to 150 study patients, beta-lactam family represents the most consum...

In this study, we used series of molecular dynamics simulations of the wild type and mutants types K164A CD36 protein interacting with one Palmitic acid (PLM) besides simulations of the wild type interacting with the three PLM to find out the mechanism of the functioning of the complex CD36/Fatty acids and the unraveling of the role of the mutation. Additionally we determined whether Lys164, mostly exposed to protein surface, played important roles in fatty acid uptake. These simulations revealed, the conformational changes induced by Lys164 residue and the altered interactions induced by the mutagenesis of surface lysine that was badly influencing the folding, utility, solubility, and stability form of the variant. Further...

Although nearly all snakes with medical relevance can induce acute renal failure (ARF), it's unusual except with bites by some viper species. ARF has very rarely been reported following Cerastes cerastes bite. A 55-year-old Moroccan man was bitten on his right hand by a Saharan horned viper, Cerastes cerastes. He presented 24 hours later in a state of confusion, agitation and hypotension with marked swelling of his right hand. Investigations revealed evidence of disseminated intravascular coagulation (DIC) and rhabdomyolysis. The appropriate antivenom was not available. Despite adequate hydration, he developed acute renal failure necessitating prolonged hemodialysis. He subsequently improved and was discharged from the hospital after four weeks with normal renal function. Although uncommon, the bite of Cerastes cerastes can result in ARF due to DIC and rhabdomyo...

Methods. This prospective study concerns hemodialysis patients; all patients were in the first step treated with conventional dialysate, and in the second step (three months later) the same patients were treated with online produced ultrapure dialysis fluid. The malondialdehyde, C-reactive protein, total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, fibrinogen, and albumin were quantified before the two steps. Results. Thirty-seven patients completed the study. Ultrapure dialysis fluid reduced but not significantly the malondialdehyde concentrations. Both dialysis fluids were associated with improvement in the malondialdehyde level before and after the hemodialysis session. In lipid parameters, there was a significant decrease with conventional dialys...

The transversal survey involved all military personnel of the Moroccan contingent and was carried out using a questionnaire to be filled out by a multidisciplinary medical team. It was performed in all the military sites and the advanced posts accessible during the period of the study. The study involved 362 male military subjects. Ninety-four adverse drug reactions were described: neuropsychiatric (anxiety, irritability, dizziness...) [n=76], digestive (anorexia, diarrhea, nausea...) [n=42], cardiovascular (tachycardia, palpitation, precordialgia...) [n=5], musculoskeletal (arthralgia, cramps) [n=4], cutaneous (redness, purpura) [n=2], and other (n=13). No "unexpected" or "serious" adverse drug reaction was reported. The causality assessment score was determined in 94 cases. Two of these reports were rated "likely", 12 "possible" and 80 doubtful. More adverse drug reactions were reported by subjects having medical and paramedical functions. During our study, mefloquine induced adverse drug reactions in a quarter of the treated subjects. Most of the adverse drug reactions were neuropsychiatric. No "serious" adverse drug reactions were reported underlying the interest of its use, even for long-term chemoprophylaxis.

The Moroccan Poison Control Center reports hundreds of snakebites every year. Being aware of this problem, Morocco started to set up a specifi c strategy for the control of snakebites since 2008. This strategy has allowed the implementation of a specifi c snakebite information system, the standardized guidelines for snakebite treatment and the acquisition and distribution of an adequate antivenom. These measures have led to an increased number of snakebites with better therapeutic management but despite these efforts, snakebites remain underestimated in Morocco.

At the time of writing, the genetic diversity of Moroccan strains of SARS-CoV-2 is poorly documented. The present study aims to analyze and identify the genetic variants of fortyeight Moroccan strains of SARS-CoV-2 collected from mid-March to the end of May and the prediction of their possible sources. Our results revealed 108 mutations in Moroccan SARS-CoV-2, 50% were non-synonymous were present in seven genes (S, M, N, E, ORF1ab, ORF3a, and ORF8) with variable frequencies. Remarkably, eight non-synonymous mutations were predicted to have a deleterious effect for (ORF1ab, ORF3a, and the N protein. The analysis of the haplotype network of Moroccan strains suggests different sources of SARS-CoV-2 infection in Morocco. Likewise, the phylogenetic analysis revealed that these Moroccan strains were closely related to those belonging to the five continents, indicating no specific strain dom...

Cette accessibilité reste avant tout tributaire du prix de vente final dont la détermination relève de la responsabilité du ministère de la santé. Au Maroc, malgré que la réglementation en vigueur a contribué à une baisse significative des prix de certains segments thérapeutiques, l’accessibilité au médicament reste très en deçà des attentes des consommateurs. De leur part, les professionnels du secteur, qui s’estiment être lésés, restent en attente d’une révision à la hausse des prix. Devant cette situation, les pouvoirs publics doivent réfléchir à un éventuel amendement de la réglementation relative aux conditions et aux modalités de fixation du prix des médicaments permettant de réaliser l’équilibre souhaité entre, d’une part, les intérêts légitimes des professionnels de l’industrie pharmaceutique, des sociétés de distribution et des pharmaciens d’officine, et ...

Pharmacy professionals, as the most available members of medical team, have an important role in educating patients about Cutaneous Adverse Drug Reaction (CADR). Our aim was to evaluate pharmacists’ knowledge of the cutaneous drug reaction, and their recommendations under hypothetical situations, through a written questionnaire. Methods. based cross-sectional study was conducted among community pharmacists working at the private sector of the rabat-sale-zemmour-zaer region using a structured interviewing questionnaire. Results. Ninety- eight pharmacists completed the questionnaire (response rate 48%). The mean overall score was 52.87 ± 23.19% correct answers. The majority of pharmacists (66,32 %) estimated that they view more than a Patient with CADR each month, and only forty-seven pharmacists underwent CADR related training during the year preceding the survey. Pharmacists obtained the highest correct scores on the true/false statements inquiring about Cutaneous reaction due to drugs definition, classification and the most common medication classes implicated in Cutaneous reaction due to drugs, Overall, the true/false questions were relatively easier to address, compared with the multiple choice questions (63.60 ± 13.15% vs. 51.18 ± 24.12%, respectively; p < 0.01). Only 14 pharmacists were familiar with Cutaneous reaction due to drugs sach as ( Drug Reaction With Eosinophilia, contact dermatitis, Nail Disorders, bullous pemphigoid ). Longer time since training completion was associated with a lower total score (38,77 ± 9% vs. 61,22 ± 11% for the pharmacists who were in practice 5 years or less and those with longer time in practice, respectively; p < 0.05). Conclusion. Pharmacists were knowledgeable regarding some aspects of CADR. However, our study, as in previous studies among health care professionals, identified some gaps in knowledge. These findings indicate the need for better education of pharmacists regarding CADR and its supported.

To this end, we aimed to explore novel inhibitor compounds that can stop replication or decrease the viral load of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), for which there is currently no approved treatment. Besides using the angiotensin-converting enzyme (ACE2) receptor as a main gate, the CoV-2 can bind to the glucose-regulating protein 78 (GRP78) receptor to get into the cells to start an infection. Here, we report potential inhibitors comprising small molecules and peptides that could interfere with the interaction of SARS-CoV-2 and its target cells by blocking the recognition of the GRP78 cellular receptor by the viral Spike protein. These inhibitors were discovered through an approach of in silico screening of available databases of bioactive peptides and polyphenolic compounds and the a...

The first one occurred from March 02, 2020 with infections mostly imported from Europe and the second one dominated by local infections.At the time of writing, the genetic diversity of Moroccan isolates of SARS-CoV-2 has not yet been reported. The present study aimed to analyze first the genomic variation of the twenty-eight Moroccan strains of SARS-CoV-2 isolated from March 03, 2020 to May 15, 2020, to compare their distributions with twelve other viral genomes from North Africa as well as to identify their possible sources.Our finding revealed 61 mutations in the Moroccan genomes of SARS-CoV-2 compared to the reference sequence Wuhan-Hu-1/2019, of them 23 (37.7%) were present in two or more genomes. Focusing on non-synonymous mutations, 29 (47.54%) were distributed in five genes (ORF1ab, spike, membrane, nucleocapsid and ORF3a) with variable frequencies. The non-structural protein coding regions nsp3-Multi domain an...

Research paper thumbnail of Genomic diversity and hotspot mutations in 30,983 SARS-CoV-2 genomes: moving toward a universal vaccine for the “confined virus”?

To date, the SARS-CoV-2 virus has infected more than 8 million people worldwide and killed over 5% of them. Efforts are being made all over the world to control the spread of the disease and most importantly to develop a vaccine. Understanding the genetic evolution of the virus, its geographic characteristics and stability is particularly important for developing a universal vaccine covering all circulating strains of SARS-CoV-2 and for predicting its efficacy. In this perspective, we analyzed the sequences of 30,983 complete genomes from 80 countries located in six geographical zones (Africa, Asia, Europe, North & South America, and Oceania) isolated from December 24, 2019 to May 13, 2020, and compared them to the reference genome. Our in-depth analysis revealed the presence of 3,206 variant sites compared to the reference Wuhan-Hu-1 genome, with a distribution tha...

Characterization of the genetic variants of SARS-CoV-2 is crucial in following and evaluating it spread across countries. In this study, we collected and analyzed 3,067 SARS-CoV-2 genomes isolated from 55 countries during the first three months after the onset of this virus. Using comparative genomics analysis, we traced the profiles of the whole-genome mutations and compared the frequency of each mutation in the studied population. The accumulation of mutations during the epidemic period with their geographic locations was also monitored. The results showed 782 variant sites, of which 512 (65.47%) had a non-synonymous effect. Frequencies of mutated alleles revealed the presence of 38 recurrent non-synonymous mutations, including ten hotspot mutations with a prevalence higher than 0.10 in this population and distributed in six SARS-CoV-2 genes. The distribution o...

La mefloquine est un derive de la quinine, commercialisee depuis 1970, elle est utilisee dans le traitement et la prophylaxie du paludisme pour les formes resistantes a la chloroquine. C’est un schizonticide agissant sur les formes intra-erythrocytaires des differents Plasmodium spp. L’objectif de notre travail est d’evaluer la survenue des effets indesirables lors de la chimioprophylaxie antipaludeenne au niveau du contingent marocain en Republique Democratique du Congo (RDC). Methodes L’enquete de type transversal, concerne les militaires du contingent marocain en RDC. Elle est realisee via un questionnaire rempli par une equipe medicale pluridisciplinaire en interrogeant les sujets dans tous les sites et les postes avances militaires accessibles pendant la periode de l’etude. Resultats L’etude portait sur 546 sujets militaires masculins. Deux cent trente-deux reactions indesirables ont ete decrites : neuropsychiatrique (anxiete, irritabilite, etourdissements [n = 142]), digestive (anorexie, diarrhee, nausee [n = 63]), cardiovasculaire (tachycardie, palpitations, precordialgie [n = 8]), musculosquelettique (arthralgie, crampes [n = 9]), cutane (rougeur, purpura [n = 3]) et autres (n = 7). Aucune reaction indesirable « inattendue » ou « grave » n’a ete signalee. L’imputabilite a ete etablie pour tous les cas d’effets indesirables (232 cas). Elle a ete cotee « douteuse » (I1) pour 183 cas (78,87 %), « plausible » (I2) pour 46 cas (19,82 %) et « vraisemblable » (I3) dans trois cas (1,29 %). Les enquetes ayant des fonctions medicales et paramedicales declarent plus d’effets indesirables. Conclusion Lors de notre etude, la mefloquine a provoque des effets indesirables chez 1/3 des sujets la recevant. La plupart des effets indesirables sont de nature neuropsychiatrique ; aucun cas d’effet indesirable « grave » n’a ete releve ce qui renforce l’interet de son utilisation en curatif et en preventif meme pendant des traitements de prophylaxie de longue duree, sous reserve du respect des precautions d’emploi et des contre-indications notamment neuropsychiatriques.

Pharmacy professionals, as the most available members of medical team, have an important role in educating patients about Cutaneous Adverse Drug Reaction (CADR). Our aim was to evaluate pharmacists’ knowledge of the cutaneous drug reaction, and their recommendations under hypothetical situations, through a written questionnaire. Methods. based cross-sectional study was conducted among community pharmacists working at the private sector of the rabat-sale-zemmour-zaer region using a structured interviewing questionnaire. Results. Ninety- eight pharmacists completed the questionnaire (response rate 48%). The mean overall score was 52.87 ± 23.19% correct answers. The majority of pharmacists (66,32 %) estimated that they view more than a Patient with CADR each month, and only forty-seven pharmacists underwent CADR related training during the year preceding the survey. Pharmacists obtained the highest correct scores on the true/false statements inquiring about Cutaneous reaction due to drugs definition, classification and the most common medication classes implicated in Cutaneous reaction due to drugs, Overall, the true/false questions were relatively easier to address, compared with the multiple choice questions (63.60 ± 13.15% vs. 51.18 ± 24.12%, respectively; p < 0.01). Only 14 pharmacists were familiar with Cutaneous reaction due to drugs sach as ( Drug Reaction With Eosinophilia, contact dermatitis, Nail Disorders, bullous pemphigoid ). Longer time since training completion was associated with a lower total score (38,77 ± 9% vs. 61,22 ± 11% for the pharmacists who were in practice 5 years or less and those with longer time in practice, respectively; p < 0.05). Conclusion. Pharmacists were knowledgeable regarding some aspects of CADR. However, our study, as in previous studies among health care professionals, identified some gaps in knowledge. These findings indicate the need for better education of pharmacists regarding CADR and its supported.

To this end, we aimed to explore novel inhibitor compounds that can stop replication or decrease the viral load of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), for which there is currently no approved treatment. Besides using the angiotensin-converting enzyme (ACE2) receptor as a main gate, the CoV-2 can bind to the glucose-regulating protein 78 (GRP78) receptor to get into the cells to start an infection. Here, we report potential inhibitors comprising small molecules and peptides that could interfere with the interaction of SARS-CoV-2 and its target cells by blocking the recognition of the GRP78 cellular receptor by the viral Spike protein. These inhibitors were discovered through an approach of in silico screening of available databases of bioactive peptides and polyphenolic compounds and the a...

SARS-CoV-2 is responsible for the COVID-19 pandemic, which started at the end of 2019 in Wuhan, China. The isolates were obtained from nasopharyngeal swabs from Moroccan patients with COVID-19. Mutation analysis revealed the presence of the spike D614G mutation in all six genomes, which is widely present in several genomes around the world.

The first one occurred from March 02, 2020 with infections mostly imported from Europe and the second one dominated by local infections.At the time of writing, the genetic diversity of Moroccan isolates of SARS-CoV-2 has not yet been reported. The present study aimed to analyze first the genomic variation of the twenty-eight Moroccan strains of SARS-CoV-2 isolated from March 03, 2020 to May 15, 2020, to compare their distributions with twelve other viral genomes from North Africa as well as to identify their possible sources.Our finding revealed 61 mutations in the Moroccan genomes of SARS-CoV-2 compared to the reference sequence Wuhan-Hu-1/2019, of them 23 (37.7%) were present in two or more genomes. Focusing on non-synonymous mutations, 29 (47.54%) were distributed in five genes (ORF1ab, spike, membrane, nucleocapsid and ORF3a) with variable frequencies. The non-structural protein coding regions nsp3-Multi domain an...

Research paper thumbnail of Genomic diversity and hotspot mutations in 30,983 SARS-CoV-2 genomes: moving toward a universal vaccine for the “confined virus”?

To date, the SARS-CoV-2 virus has infected more than 8 million people worldwide and killed over 5% of them. Efforts are being made all over the world to control the spread of the disease and most importantly to develop a vaccine. Understanding the genetic evolution of the virus, its geographic characteristics and stability is particularly important for developing a universal vaccine covering all circulating strains of SARS-CoV-2 and for predicting its efficacy. In this perspective, we analyzed the sequences of 30,983 complete genomes from 80 countries located in six geographical zones (Africa, Asia, Europe, North & South America, and Oceania) isolated from December 24, 2019 to May 13, 2020, and compared them to the reference genome. Our in-depth analysis revealed the presence of 3,206 variant sites compared to the reference Wuhan-Hu-1 genome, with a distribution tha...

Characterization of the genetic variants of SARS-CoV-2 is crucial in following and evaluating it spread across countries. In this study, we collected and analyzed 3,067 SARS-CoV-2 genomes isolated from 55 countries during the first three months after the onset of this virus. Using comparative genomics analysis, we traced the profiles of the whole-genome mutations and compared the frequency of each mutation in the studied population. The accumulation of mutations during the epidemic period with their geographic locations was also monitored. The results showed 782 variant sites, of which 512 (65.47%) had a non-synonymous effect. Frequencies of mutated alleles revealed the presence of 38 recurrent non-synonymous mutations, including ten hotspot mutations with a prevalence higher than 0.10 in this population and distributed in six SARS-CoV-2 genes. The distribution o...

La mefloquine est un derive de la quinine, commercialisee depuis 1970, elle est utilisee dans le traitement et la prophylaxie du paludisme pour les formes resistantes a la chloroquine. C’est un schizonticide agissant sur les formes intra-erythrocytaires des differents Plasmodium spp. L’objectif de notre travail est d’evaluer la survenue des effets indesirables lors de la chimioprophylaxie antipaludeenne au niveau du contingent marocain en Republique Democratique du Congo (RDC). Methodes L’enquete de type transversal, concerne les militaires du contingent marocain en RDC. Elle est realisee via un questionnaire rempli par une equipe medicale pluridisciplinaire en interrogeant les sujets dans tous les sites et les postes avances militaires accessibles pendant la periode de l’etude. Resultats L’etude portait sur 546 sujets militaires masculins. Deux cent trente-deux reactions indesirables ont ete decrites : neuropsychiatrique (anxiete, irritabilite, etourdissements [n = 142]), digestive (anorexie, diarrhee, nausee [n = 63]), cardiovasculaire (tachycardie, palpitations, precordialgie [n = 8]), musculosquelettique (arthralgie, crampes [n = 9]), cutane (rougeur, purpura [n = 3]) et autres (n = 7). Aucune reaction indesirable « inattendue » ou « grave » n’a ete signalee. L’imputabilite a ete etablie pour tous les cas d’effets indesirables (232 cas). Elle a ete cotee « douteuse » (I1) pour 183 cas (78,87 %), « plausible » (I2) pour 46 cas (19,82 %) et « vraisemblable » (I3) dans trois cas (1,29 %). Les enquetes ayant des fonctions medicales et paramedicales declarent plus d’effets indesirables. Conclusion Lors de notre etude, la mefloquine a provoque des effets indesirables chez 1/3 des sujets la recevant. La plupart des effets indesirables sont de nature neuropsychiatrique ; aucun cas d’effet indesirable « grave » n’a ete releve ce qui renforce l’interet de son utilisation en curatif et en preventif meme pendant des traitements de prophylaxie de longue duree, sous reserve du respect des precautions d’emploi et des contre-indications notamment neuropsychiatriques.
