Abstract
Background The SARS-CoV-2 is an extremely contagious and acute viral disease mainly affecting humans. Objective To estimate seroprevalence of SARS-CoV-2 neutralizing antibodies (NAbs) for illegible armed force individuals living in Rabat, Morocco. Method A convenience sample (N = 2662) was conducted from May 2020 to February 2021. We used the standard neutralization assay to quantify the NAbs titers. A serum was positive when the titer was 1:4. High positive NAbs titers were defined when ≥ 1:32. Results Demographic and socioeconomic status did not affect seroprevalence data. An overall seroprevalence of 24,9% was found. Sera from blood donors, young recruits and auto-immune population had lower NAbs titers. However, titers were above 1:16 in 9% of the population with high risk of SARS-CoV-2 exposure. Seropositivity increased over time with values reaching peaks after the epidemic waves (2.4% in May 2020; 16.2% in August 2020; 22.7% in December 2020 and 37% in February 2021). Conclusion And increase of NAbs was observed over time and correlated with the post-epidemic waves of COVID-19 in Morocco.

Abstract
216 Background: Morocco has the highest cancer mortality rate in MENA Countries. Colorectal cancer (CRC) is classified as the first digestive cancer and remains a burden in Morocco. According to the data on GLOBOCAN 2020, there were 4324 new CRC patients and 2374 deaths, accounting for 7.3% and 2.8% of all cancers, respectively. Our study aimed to investigate the frequency of the full RAS ( KRAS, NRAS) and BRAF genes in CRC patients from Morocco and their possible associations with clinico-pathological features. Methods: Archived FFPE of 169 CRC patients were screened for KRAS, NRAS and BRAF mutations by Idylla technology. Results: Full RAS mutations were identified in 46.1% (42% in KRAS, 4.1% in NRAS). In KRAS gene, exon 2 mutations accounted for 84.5% (69% in codon 12, 15.5 % in codon 13). Within codon 12, KRAS G12D and G12C were more frequently detected (29.5% and 16.9%, respectively). Detection of KRAS mutations, and particularly G12D and G12C subtypes, are of large significance for CRC patients, have possible therapeutic implications. Within codon 13, the most frequently observed mutation was G13D (15.5 %). Outside exon 2, the mutation rate was 35.1% (8.4% in exon 3 and 26.7% in exon 4). Concurrent KRAS mutations were identified in 8 cases, which suggests that multiple mutations can occur in the same or different codons. In NRAS gene, the mutation rates of exon 2 and 3 were 71.4% and 57.1% respectively. G13V and Q61K were the most common mutations, accounting for 28.6 % of each. Concurrent KRAS mutations were identified in 2 cases. Of the 169 samples, mutations in the BRAF gene at V600E were detected in 3.5%. Combined mutational analysis of KRAS, NRAS and BRAF was able to identify 49.6% of patients with CRC as likely non-responders to anti-EGFR therapy. There was an association between KRAS mutations and age, which were higher in the age group>50 years old (p=0.022). Tumors in the left colon (36.61%) are more likely to harbor mutations in KRAS than the rectum (19.7%) in both sexes. The adenocarcinoma well-differentiated was the most frequent for patients with KRAS mutations (54.9%). No significant clinicopathologic correlations with NRAS and BRAF mutations were identified. Conclusions: Beside established anti-CRC treatment, better understanding of the causality of CRC can be established by combining epidemiology and genetic/epigenetic on CRC etiology in Morocco. This approach may be able to significantly reduce the burden of disease in the country. Moreover, the Moroccan government should develop policy on CRC prevention and public health programs which may serve as a feasible setting to increase public awareness on lifestyle risk factors.

Abstract
Background Our review discuss (i) the findings from analyzed data that have examined KRAS, NRAS and BRAF mutations in patients with colorectal cancer (CRC) in North Africa and to compare its prevalence with that shown in other populations and (ii) the possible role of dietary and lifestyle factors with CRC risk. Methods Using electronic databases, a systematic literature search was performed for the KRAS, NRAS, and BRAF mutations in CRC patients from Morocco, Tunisia, Algeria and Lybia. Results Seventeen studies were identified through electronic searches with six studies conducted in Morocco, eight in Tunisia, two in Algeria, and one in Libya. A total of 1843 CRC patients were included 576 (31.3%) in Morocco, 641 (34.8%) in Tunisia, 592 (32.1%) in Algeria, and 34 (1.8%) in Libya. Overall, the average age of patients was 52.7 years old. Patients were predominantly male (56.6%). The mutation rates of KRAS, NRAS and BRAF were 46.4%, 3.2% and 3.5% of all patients, respectively. A broad range of reported KRAS mutation frequencies have been reported in North Africa countries. The KRAS mutation frequency was 23.9% to 51% in Morocco, 23.1% to 68.2% in Tunisia, 31.4% to 50% in Algeria, and 38.2% in Libya. The G12D was the most frequently identified KRAS exon 2 mutations (31.6%), followed by G12V (25.4%), G13D (15.5%), G12C (10.2%), G12A (6.9%), and G12S (6.4%). G12R, G13V, G13C and G13R are less than 5%. There are important differences among North Africa countries. In Morocco and Tunisia, there is a higher prevalence of G12D mutation in KRAS exon 2 (≈50%). The most frequently mutation type in KRAS exon 3 was Q61L (40%). A59T and Q61E mutations were also found. In KRAS exon 4, the most common mutation was A146T (50%), followed by K117N (33.3%), A146P (8.3%) and A146V (8.3%). Conclusion KRAS mutated CRC patients in North Africa have been identified with incidence closer to the European figures. Beside established anti-CRC treatment, better understanding of the causality of CRC can be established by combining epidemiology and genetic/epigenetic on CRC etiology. This approach may be able to significantly reduce the burden of CRC in North Africa.

Abstract
BACKGROUND We aimed to analyze for the first time in Morocco the integrase (IN) sequence variability among highly experienced HIV-1-infected patients with no prior IN strand transfer inhibitor (INSTI) exposure who failed on reverse transcriptase inhibitors and protease inhibitors. METHODS The HIV-1 IN region was sequenced from plasma samples of all 78 recruited patients. The amino acid IN sequences were HIV-1 subtyped and screened for the presence of polymorphisms against the HxB2 clade B consensus sequence by the geno2pheno subtyping tool and interpreted for drug resistance according to the Stanford algorithm. RESULTS The viral subtypes were subtype B (88.4%), CRF02_AG (8.9%), CRF01_AE (1.28%), and subtype C (1.28%). The major INSTI resistance mutations at positions 66, 92, 118, 138, 140, 143, 147, 148, 155, and 263 were absent, while two accessory mutations, L74M/I, known to have no clinical impact to INSTIs in the absence of the major resistance mutations, were detected in three samples (3.84%; two CRF02_AG and one CRF01_AE). Others specific substitutions with an uncertain role on the HIV-1 susceptibility to INSTIs at positions 72, 101, 119, 124, 156, 165, 193, 201, 203, 206, 230, 232, and 249 were found to be relatively common. CONCLUSION This study demonstrated that INSTIs should be an excellent alternative for salvage therapy in highly experienced patients with multidrug resistant viruses in Morocco.

Objective The integrase strand-transfer inhibitors (INSTIs) are an important class in the arsenal of antiretroviral drugs designed to block the integration of HIV-1 cDNA into the host DNA through the inhibition of DNA strand transfer. In this study for the first time in Morocco, the complete HIV-1 integrase gene was analysed from newly diagnosed patients to evaluate the prevalence of natural polymorphisms and INSTIs resistance-associated mutations in the integrase gene. Results The 864pb IN coding region was successfully sequenced from plasma sample for 77 among 80 antiretroviral naïve patients. The sequences were interpreted for drug resistance according to the Stanford algorithm. Sixty samples were HIV-1 subtype B (78%), fourteen CRF02_AG (18%), two subtype C and one subtype A. Overall 81 of 288 (28%) amino acid IN positions presented at least one polymorphism each. We found 18 (36.73%), 42 (25.76%) and 21 (27.27%) of polymorphic residues assigned to the N-Terminal Domain, Catalytic Core Domaine and the C-Terminal Domain positions respectively. Primary INSTIs resistance mutation were absent, however secondary mutations L74IM, T97A were detected in four samples (5.2%). These results demonstrate that untreated HIV-1 infected Moroccans will be susceptible to INSTIs.

Abstract
BACKGROUND Vaccination of health-care workers (HCWs) against seasonal influenza has been consistently recommended worldwide in order to prevent nosocomial transmission and ensure delivery of health-care services during outbreaks. Overall, immunization rates were low across all nation, including among HCWs. Little is known about the acceptability and compliance with seasonal influenza vaccine among HCWs after the A(H1N1) 2009 pandemic. PARTICIPANTS AND SETTING Between 1st and 31 January 2011, we conducted a questionnaire-based survey at the Ibn Sina regional center (Rabat, Morocco). Seven hundred twenty one HCWs have answered about their influenza immunization during the 2010/2011 season, as well as the reasons for accepting or declining this vaccine. Finally, we compare our results with previous moroccan survey. RESULTS A total of 122 HCWs (17%) reported having received the 2010/2011 seasonal vaccine; "self-protection" and "protection of the patient" were the most frequently adduced reasons for acceptance of the influenza vaccination, whereas media controversy during the pandemic was the main argument for refusal. DISCUSSION The post pandemic seasonal influenza vaccination coverage among the HCWs in our institution was very low. The role of media, specific attitudinal barriers and misconceptions about immunization in a global pandemic scenario is clear. The nearly constant media coverage of the A (H1N1) 2009 pandemic, reported with varying degrees of accuracy, and sometimes portraying dramatic scenarios caused some to question whether unnecessary alarm and public panic resulted. We suggest that international or national health authorities have a clear speech over looked media and to own these institutions, which will air fair and real time information about the disease.

Abstract
The emergence of viral-resistant strains is a major problem for the medical management of HIV-infected individuals. The aim of this study was to characterize viral subtypes and drug-resistance mutations (DRMs) in HIV-1 isolates from patients failing antiretroviral therapy (ART). A total of 45 HIV-1-infected patients failing ART were enrolled. The viral RT and Prot genes were amplified and sequenced to determine subtypes and potential DRMs. The subtype distribution was 74% subtype B, 11% subtype A, 9% CRF02-AG, 4% subtype G, and 2% subtype C. Virus samples from 34% of the patients had no DRM while 53%, 27%, and 2% of samples carried at least one DRM conferring resistance to drugs of one, two, or three classes, respectively. DRMs were observed in 50% of the patients infected with non-B strains. The prevalence of nucleoside transcriptase inhibitor (NRTI) mutations was 48%, M184V being largely predominant. The prevalence of nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations was 13%, with K103N present in 57% of samples from NNRTIs-exposed patients. The prevalence of protease inhibitor (PI) mutations was 22%, with major mutations V82A and M46I seen in 16% and 11% of viruses from PI-exposed individuals, respectively. Our study shows the emergence of DRMs in HIV-1 isolates from Moroccan patients failing ART. Although not surprising, the data plead for longitudinal surveys of the dynamics of emergence of DRMs (with a focus on multidrug resistance) in treated patients and circulation of resistant HIV-1 strains in this country.

Abstract
The aim of the present study was to determine viral subtypes and resistance mutations to antiretroviral treatment (ART) in HIV-1-infected treatment-naive patients from Rabat, Morocco during the period 2005-2009. The protease and reverse transcriptase (RT) genes were sequenced, the phylogenetic trees were inferred, and the resistance-associated mutations to NRTIs, NNRTIs, and PIs were recorded according to the international list of surveillance drug resistance mutations (SDRMs). The viral subtypes were subtype B (74%), CRF02_AG (15%), A1 (6%), C (2%), F1 (1%), CRF09 (1%), and CRF25_cpx (1%). The presence of DRMs was found in four (5.06%) of 91 patients; resistance mutations to NRTIs were M184V and T215I/S revertant mutations; resistance to NNRTIs was associated with K103N and resistance to PIs with V82A. These findings have relevant implications for the local molecular mapping of HIV-1 and future ART surveillance studies in the region.
