Abstract
Monkeypox virus (MPV) is closely related to the smallpox virus, and previous data from Africa suggest that the smallpox vaccine (VARV) is at least 85% effective in preventing MPV. No multi-epitope vaccine has yet been developed to prevent MPV infection. In this work, we used in silico structural biology and advanced immunoinformatic strategies to design a multi-epitope subunit vaccine against MPV infection. The designed vaccine sequence is adjuvanted with CpG-ODN and includes HTL/CTL epitopes for similar proteins between vaccinia virus (VACV) that induced T-cell production in vaccinated volunteers and the first draft sequence of the MPV genome associated with the suspected outbreak in several countries, May 2022. In addition, the specific binding of the modified vaccine and the immune Toll-like receptor 9 (TLR9) was estimated by molecular interaction studies. Strong interaction in the binding groove as well as good docking scores confirmed the stringency of the modified vaccine. The stability of the interaction was confirmed by a classical molecular dynamics simulation and normal mode analysis. Then, the immune simulation also indicated the ability of this vaccine to induce an effective immune response against MPV. Codon optimization and in silico cloning of the vaccine into the pET-28a (+) vector also showed its expression potential in the E. coli K12 system. The promising data obtained from the various in silico studies indicate that this vaccine is effective against MPV. However, additional in vitro and in vivo studies are still needed to confirm its efficacy.Communicated by Ramaswamy H. Sarma.

Abstract
BACKGROUND Hepatitis A virus (HAV) is the common cause of acute hepatitis worldwide. Indeed, hepatitis A is endemic in developing countries such in Morocco and most residents are exposed in childhood. The characterisation of circulating strains of HAV remains crucial to understand the virological evolution and geo-temporal characteristics, which are essential for controlling infections and outbreaks. The purpose of the current study was the detection and characterisation of HAV strains circulating in Morocco by performing serological test, RT-PCR, sequencing and phylogenetic analysis. METHODS In this cross-sectional study, 618 suspected acute hepatitis cases were examined by Architect HAV abIgM. Of the 162 positives, 64 underwent RNA extraction. None of the suspected cases was immune to HAV and none of them had received a blood transfusion. Samples found positive by RT-PCR using primers targeting the VP1/VP2A junction and the VP1/VP3 capsid region of HAV were subjected to sequencing and phylogenetic analyses. RESULTS HAV Acute infection rate was 26.2% [95% CI, 22.8-29.9], while viraemia reached 45% (29/64) after amplification of the VP3/VP1 region. Phylogenetic analysis of the VP1/2A segment revealed the presence of sub-genotypes IA and IB. Eighty-seven percent of the strains belonged to the subgenotype IA, while twelve percent to IB subgenotype. CONCLUSION This first molecular study of acute hepatitis A in Morocco provided information about genetic diversity of HAV, revealing the co-circulating of only two subgenotypes (IA and IB). Notably, subgenotype IA was found to be the predominant subgenotype in Morocco.

Abstract
BACKGROUND Chronic hepatitis B virus (CHB) infection is still incurable a major public health problem. It is yet unclear how host genetic factors influence the development of HBV infection. The peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PPARGC1A) has been shown to regulate hepatitis B virus (HBV). Several reports found that PPARGC1A variants are involved in a number of distinct liver diseases. Here we investigate whether the PPARGC1A rs8192678 (Gly482Ser) variant is involved in the spontaneous clearance of acute HBV infection and if it participates in chronic disease progression in Moroccan patients. METHODS Our study included 292 chronic hepatitis B (CHB) patients and 181 individuals who spontaneously cleared-HBV infection. We genotyped the rs8192678 SNP using a TaqMan allelic discrimination assay and then explored its association with spontaneous HBV clearance and CHB progression. RESULTS Our data showed that individuals carrying CT and TT genotypes were more likely to achieve spontaneous clearance (OR = 0.48, 95% CI (0.32-0.73), p = 0.00047; OR = 0.28, 95% CI (0.15-0.53), p = 0.00005, respectively). Subjects carrying the mutant allele T were more likely to achieve spontaneous clearance (OR = 0.51, 95% CI (0.38-0.67), P = 2.68E-06). However, when we investigated the impact of rs8192678 on the progression of liver diseases, we neither observe any influence (p > 0.05) nor found any significant association between ALT, AST, HBV viral loads, and the PPARGC1A rs8192678 genotypes in patients with CHB (p > 0.05). CONCLUSION Our result suggests that PPARGC1A rs8192678 may modulate acute HBV infection, and could therefore represent a potential predictive marker in the Moroccan population.

Abstract
Zika virus (ZIKV) is a mosquito-borne human flavivirus responsible that causing emergency outbreaks in Brazil. ZIKV is suspected of causing Guillain-Barre syndrome in adults and microcephaly. The NS2B-NS3 protease and NS5 RNA-dependent RNA polymerase (RdRp), central to ZIKV multiplication, have been identified as attractive molecular targets for drugs. We performed a structure-based virtual screening of 2,659 FDA-approved small molecule drugs in the DrugBank database using AutoDock Vina in PyRx v0.8. Accordingly, 15 potential drugs were selected as ZIKV inhibitors because of their high values (binding affinity - binding energy) and we analyzed the molecular interactions between the active site amino acids and the compounds. Among these drugs, tamsulosin was found to interact most efficiently with NS2B/NS3 protease, as indicated by the lowest binding energy value (-8.27 kJ/mol), the highest binding affinity (-5.7 Kcal/mol), and formed H-bonds with amino acid residues TYRB130, SERB135, TYRB150. Furthermore, biotin was found to interact most efficiently with NS5 RdRp with a binding energy of -150.624 kJ/mol, a binding affinity of -5.6 Kcal/mol, and formed H-bonds with the amino acid residues ASPA665 and ASPA540. In vitro, in vivo, and clinical studies are needed to demonstrate anti-ZIKV safety and the efficacy of these FDA-approved drug candidates.Communicated by Ramaswamy H. Sarma.

Abstract
Chronic inflammation and immune activation are a hallmark of HIV-1 infection. In this study, we assessed inflammation biomarkers in a cohort of people living with HIV-1 (PLWH) before and after long-term suppressive combined antiretroviral therapy (cART). A single-center prospective cohort study was conducted to assess inflammatory biomarkers in 86 cART-naive PLWH and after receiving suppressive cART and 50 uninfected controls. Tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and soluble CD14 (sCD14) were measured using enzyme-linked immunosorbent assay (ELISA). No significant difference was found in IL-6 levels between cART-naïve PLWH and controls (p = 0.753). In contrast, TNF-α level showed a significant difference between cART naïve-PLWH and controls (p = 0.019). Interestingly, IL-6 and TNF-α levels were significantly decreased in PLWH after cART (p < 0.0001). The sCD14 showed no significant difference between cART-naïve patients and controls (p = 0.839) and similar levels were observed in pre- and post-treatment (p = 0.719). Our results highlight the critical importance of early treatment to reduce inflammation and its consequences during HIV infection.

Abstract
Human immunodeficiency virus type 1 (HIV-1) infection varies substantially among individuals. One of the factors influencing viral infection is genetic variability. Methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism is a genetic factor that has been correlated with different types of pathologies, including HIV-1. The MTHFR gene encodes the MTHFR enzyme, an essential factor in the folate metabolic pathway and in maintaining circulating folate and methionine at constant levels, thus preventing the homocysteine accumulation. Several studies have shown the role of folate on CD4+ T lymphocyte count among HIV-1 subjects. In this case-control study we aimed to determine the association between the MTHFR C677T polymorphism and HIV-1 infection susceptibility, AIDS development, and therapeutic outcome among Moroccans. The C677T polymorphism was genotyped by polymerase chain reaction followed by fragment length polymorphism digestion in 214 participants living with HIV-1 and 318 healthy controls. The results of the study revealed no statistically significant association between MTHFR C677T polymorphism and HIV-1 infection (P > .05). After dividing HIV-1 subjects according to their AIDS status, no significant difference was observed between C677T polymorphism and AIDS development (P > .05). Furthermore, regarding the treatment response outcome, as measured by HIV-1 RNA viral load and CD4+ T cell counts, no statistically significant association was found with MTHFR C677T polymorphism. We conclude that, in the genetic context of the Moroccan population, MTHFR C677T polymorphism does not affect HIV-1 infection susceptibility, AIDS development, or response to treatment. However, more studies should be done to investigate both genetic and nutritional aspects for more conclusive results.

Abstract
Sternal osteomyelitis due to aspergillosis is extremely rare. Among all cases of invasive aspergillosis reported in the literature, the incidence of osteomyelitis is less than 3%. Aspergillosis mainly affects immunosuppressed patients. Clinical and radiological manifestation is nonspecific. Contamination is primarily caused by inhaling spores, but it can also directly reach a vulnerable area after medical procedure. Diagnosis is often difficult and may take several weeks, in particular when aspergillosis is not suspected. Positive diagnosis is based on imaging tests but it is confirmed by anatomopathological and/or mycological examinations. Prognosis mainly depends on early administration of treatment. We here report the case of a 63-year-old diabetic patient with sternocostal osteomyelitis due to Aspergillus occurred after coronary angioplasty.

Abstract
Human Immunodeficiency Virus (HIV-1) infections are characterized by dysfunctional cellular and humoral antiviral immune responses. The progressive loss of effector functions in chronic viral infection has been associated with the up-regulation of programmed death-1 (PD-1), a negative regulator of activated T cells and Natural Killer cells. In HIV-1 infection, increased levels of PD-1 expression correlate with CD8 + T-cell exhaustion. In vitro, PD-1 blockade using PD-1 antibodies led to an increase in HIV-1 specific CD8 + T and memory B cell proliferation. We aimed to investigate the impact of PDCD1 rs10204525 polymorphism on HIV-1 susceptibility, AIDS development, and treatment response outcomes in HIV-1 infection in a Moroccan population. A total of 214 HIV-1 seropositive and 250 seronegative subjects were enrolled to investigate the association between the between the single-nucleotide polymorphism (SNP) rs10204525 of PDCD1 gene and HIV-1 pathogenesis using a predesigned TaqMan SNP genotyping assay. No significant association was found between rs10204525 and susceptibility to HIV-1 infection and AIDS development (p > 0.05). Genotype frequencies were significantly associated with the viral load before ART (p = 0.0105). HIV-1 viral load was significantly higher among subjects with the CC compared to TT genotype (p = 0.0043). In treated subjects, the median of viral load levels was significantly higher in CC and CT groups than TT subjects (p < 0.005). However, analysis of the correlation between CD4 + T-cell levels and PDCD1 polymorphism before and after ART showed no significant difference (p > 0.05). Our results demonstrated that rs10204525 polymorphism does not affect HIV-1 infection. However, this polymorphism may affect the response to treatment as measured by RNA viral load levels.

Abstract
BACKGROUND It has been reported that interferon-λ3 (IFNL3)might influence the pathogenesis and clearance of human papillomavirus (HPV) infection. The impact of IFNL3 single-nucleotide polymorphism (SNP) on HPV infection is currently unknown. The aim of this study was to investigate the association between variants in the IFNL3 region and HPV infection in women with human immunodeficiency virus (HIV) infection. METHODS A total of 236 HIV patients, including 65 HPV-negative and 171 HPV DNA-positive women, were enrolled into this study. The IFNL3 rs12979860 polymorphism was genotyped using a predesigned TaqMan SNP genotyping assay. RESULTS Data showed no significant differences in genotypes or allele frequencies between the HPV DNA-positive and the HPV-negative women (p > 0.05). After dividing the HPV-positive women according to cytology results into patients with abnormal and normal lesions, the genotype and allele distribution of the SNP did not significantly differ between the 2 groups (p > 0.05). CONCLUSIONS Our results showed that the IFNL3 rs12979860 polymorphism is not a major determinant of the susceptibility to HPV infection and their progression to abnormal cervical lesions in women living with HIV.

Abstract
Introduction: Women infected with human immunodeficiency virus (HIV) have a higher risk of contracting human papillomavirus (HPV) infections and are more prone to develop cervical cancer. The objective of this study was to determine the prevalence of HPV and its association with risk factors among Moroccan women living with HIV/AIDS.
Methodology: We enrolled 251 HIV-infected non-pregnant women in Morocco from February 2013 to September 2016. Sociodemographic, lifestyles, behavioral and clinical data were collected. Polymerase chain reaction followed by sequencing were performed for molecular detection and HPV genotyping in cervical samples, respectively.
Results: Abnormal cervical smears were found in 34/246 patients (13.82%). The overall prevalence of HPV was 74.50%. HPV 58 was the most prevalent (39.29%) followed by HPV 18 (10.71%), HPV 70 (8.93%), HPV 33 (7.14%), HPV 6 (6.25%) and other genotypes (< 3%). Overall, high-risk HPV (HR-HPV) types were present in 75% (84/112) of patients and the prevalence of HR-HPV types in samples with abnormal Pap was higher than in normal Pap (55/83, 66.27% vs. 28/83, 33.33%, p < 0.0001). Univariate analyses showed that none of the socio-demographic and behaviors factors was associated with HPV infection. Moreover, Pap results were not affected by HPV status (p = 0.532). Whereas, CD4 T-cell counts above 200/mm3 at enrolment were apparently not protective to HPV infection. We found a high prevalence of HPV infection and HR-HPV types among HIV-positive women that significantly associated with abnormal Pap.
Conclusion: Our findings suggest a high prevalence of HPV infection with high-risk types was observed among HIV-positive women warrant to implement a regular screening by Pap smear.

Abstract
Cryptococcosis is a cosmopolitan fungal serious condition due to an encapsulated yeast Cryptococcus neoformans. This is the systemic fungal infection the most common in HIV infection. This yeast is present in the environment and its main entrance in the body is the respiratory tract. Its gravity is linked to its tropism for the central nervous system. It generally affects subjects with severe deficit of cellular immunity and in particular, patients living with HIV. The diagnosis of neuromeningeal cryptococcosis is based on the detection of encapsulated yeasts at microscopic examination of cerebrospinal fluid, the detection of capsular polysaccharide antigen in serum or cerebrospinal fluid, but especially on the culture. A staging is always essential. The prognosis is severe. The control of intracranial hypertension is a major element of prognosis.

Abstract
In order to investigate the association between length variation of the CD209L neck region and human immunodeficiency virus (HIV)-1 susceptibility, disease progression, and treatment response outcomes, we genotyped 139 HIV-1-seropositive and 109 seronegative individuals. The heterozygous genotype 6/5 showed a significant increased risk of HIV-1 infection (OR 3.03, 95% CI 0.99-9.33, p 0.046). Moreover, after highly active antiretroviral therapy (HAART), HIV-1-seropositive individuals carrying the 6/5, 7/5 and 7/7 genotypes and alleles 5, 6 and 7 showed good CD4(+) T-cell recovery. In addition, individuals with the 7/5, 6/6 and 7/7 genotypes showed a significant decrease in viral load during the treatment period as compared with baseline (p < 0.05). Interestingly, we found that alleles 4 and 6 were associated with protection against AIDS progression. D209L variation may influence susceptibility to HIV-1, response to treatment, and disease progression.

Abstract
Human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) are major public health concerns. We aimed to determine the prevalence of HBV and HCV infections among HIV-infected patients, and to identify the main circulating hepatitis strains in Morocco. The study was carried out in 503 HIV-infected patients. Our survey indicated that the prevalence of HIV/hepatitis co-infection was 10.6%; 5.2% of patients were HBV surface antigen positive, and 5.4% of patients were anti-HCV positive. Among the HBV surface antigen-positive group, HBV DNA sequencing identified exclusively genotype D (D1: 26.7%; D7: 73.3%) in accordance with what is found in the general population. In contrast, sequencing of HCV isolates produced an unusual subtype distribution with a decreasing order of prevalence: 1a, 3a (both 23.5%), 1b, 4a (both 17.6%), 1c (11.8%) and 6h (6%).

Abstract
The purpose of this study was to investigate the amino acid substitutions in the protease of HIV-1 B and non-B subtypes and evaluate whether the emergence of resistance-associated mutations (RAMs) could have a significant correlation with the increasing prevalence of CRF02_AG strains in Morocco. A total of 162 protease gene sequences were successfully amplified from drug-naive HIV-1-infected individuals. We identified eight (sub)subtypes and CRFs: B(66%), A1(3.7%), C(1.2%), F1(0.6%), F2(0.6%), G(1.2%), CRF02_AG(25.3%), and CRF01_AE(1.2%). Phylogenetic analysis of CRF02_AG strains showed that 9.8% of isolates had a closer connection with reference strains from Morocco and 15.4% clustered with reference strains from eight West African and three European countries. When compared to the B subtype, patients with the CRF02_AG strain had a significantly higher prevalence of mutations associated with resistance to some antiprotease drugs, mainly tipranavir (TPV): H69K (97% vs. 5%; p<0.0001), L89M (95% vs. 1%; p<0.0001), and M36I/L (93% vs. 44%; p<0.0001). Most of the CRF02_AG strains (97%) significantly showed at least two TPV-RAMs (p=0.002) compared to the B subtype (7%). Multivariate analysis revealed that CRF02_AG infection was the only factor highly associated with the occurrence of more than two TPV-RAMs (C=0.42; p<0.0001). These results support the importance of transmitted drug resistance mutations (M36I/L, H69K, and L89M) in the protease gene of HIV-1 CRF02_AG isolates. This HIV drug resistance transmission before protease inhibitor (PI) exposure raises concern about its influence on the susceptibility of CRF02_AG strains to some PIs, especially tipranavir, which will soon be introduced as part of the second line therapeutic regimens in Morocco.

Abstract
The occurrence of invasive pulmonary aspergillosis is unusual during the course of AIDS. Patients at risk have a CD4 T-lymphocyte count under 50 cells/mm(3) combined with other risk factors in 50% of the cases. Positive diagnosis is based on chest CT scan imaging and isolation of Aspergillus in broncho-alveolar fluid. Detection of galactomannan antigen in serum and broncho-alveolar lavage fluid (BALF) is a reliable complementary tool in assessing the diagnosis. The first line therapy is Voriconazole. The prognosis, often severe, depends on prompt initiation of the appropriate antifungal treatment. We report two cases of invasive pulmonary aspergillosis in AIDS patients.
