Abstract
Chronic inflammation triggered by hepatitis B (HBV) and hepatitis C (HCV) viruses elevates interleukin 6 (IL-6) levels, activating pathways that cause liver damage and contribute to hepatocellular carcinoma (HCC) development. In this study, we assessed IL-6 levels and explored the correlation between the rs1800795 and rs1800797 variants of the IL-6 gene and the risk of developing HCC. We conducted a case-control study involving 314 participants. Among them, 157 were HCC patients (94 anti-HCV, 22 HBsAg and 41 metabolic dysfunction-associated steatotic liver disease [MASLD]) and 157 controls. Genotyping for IL-6 rs1800795 and rs1800797 polymorphisms was performed using real-time polymerase chain reaction (PCR). Additionally, plasma IL-6 levels were determined using enzyme-linked immunosorbent assay. The IL-6 levels were notably higher in patients compared to controls (p < .0001). Among HCC patients, those with MASLD exhibited higher plasma IL-6 levels than those with HCV and HBV (p = .003). In male HCC patients, IL-6 levels were significantly elevated compared to controls (p < .0001). Similarly, female patients showed significantly higher IL-6 levels compared to female controls, though still lower than in male HCC patients (p = .023). However, no significant difference was observed in IL-6 levels between male and female HCC patients (p = .129). Contrastingly, the genotype and allele distributions of the rs1800795 and rs1800797 polymorphisms in the IL-6 gene displayed no association with HCC development (all p > .005). In Moroccan HCC patients, chronic liver inflammation is characterized by elevated levels of IL-6, potentially playing a role in the progression of liver disease and tumourigenesis.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most common primary malignancy. Peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PPARGC1A) plays a crucial role in regulating the biogenesis of mitochondria. We aimed to assess the association between PPARGC1A polymorphisms and HCC risk in a Moroccan population. METHODS In this case-control study, 147 patients with HCC and 147 controls without pre-existing liver disease were matched for ethnicity. TaqMan SNP allelic discrimination assays were used for genotyping of PPARGC1A rs8192678 and rs12640088 polymorphisms. RESULTS The result revealed that individuals with the GA/AA genotypes for rs8192678 had a significantly higher risk of HCC compared to those with the GG genotype (OR=6.68; P<0.0001, and OR=9.78; P<0.0001, respectively). In particular, the A allele of rs8192678 was over-represented in HCC patients compared to controls (40% versus 12%, P<0.0001, respectively). With respect to PPARGC1A rs12640088 variant, two genetic models (codominant and dominant) were tested to explore any potential variations in the distribution of SNP A>C among HCC cases and control subjects group. Overall, no significant association between rs12640088 and HCC was found (P>0.05). Interestingly, a significantly higher level of aspartate aminotransferase was observed in HCC patients with GG-GA genotypes (280 IU/L) compared to those with GG genotype (164 IU/L) at rs8192678 (P=0.0019). CONCLUSION Our results suggest that the PPARGC1A rs8192678 polymorphism is associated with an increased risk of HCC in Moroccan population and may serve as a prognostic marker for liver cancer.

Abstract
Cutaneous leishmaniasis (CL) due to Leishmania tropica is a neglected tropical disease characterized by a wide geographical distribution in the Mediterranean basin and is endemic in several of its countries. In addition, the vector Phlebotomus sergenti is abundantly present all around the basin. Its transmission cycle is still subject to debate. In some countries, the presence of an animal reservoir has been confirmed. In Morocco, CL due to L. tropica has risen since the 1980s and has spread widely to become the most abundant form of leishmaniasis in the territory. However, the anthroponotic transmission is so far the only recognized mode, despite recordings of L. tropica infection in animal hosts. In this review article, we assess the situation of CL due to L. tropica in the Mediterranean basin with a focus on Morocco and gather knowledge about any potential zoonotic transmission in the country. A concomitant zoonotic transmission could explain the persistence of the disease in areas where human protective measures combined with vector management did not help reduce the disease burden. Cutaneous leishmaniasis (CL) due to Leishmania tropica is a neglected tropical disease still considered to be anthroponotic in Morocco despite evidence of zoonotic transmission in other endemic countries of the Mediterranean basin. Its high incidence in the country makes it necessary to investigate whether or not a potential concomitant zoonotic transmission exists alongside the anthroponotic one. Moreover, several reports of natural animal infection have been noted in the country. In this paper, we review how CL due to L. tropica is present around the Mediterranean basin, with a particular focus on the Moroccan foci, and try to unveil the existence of a zoonotic transmission in the area. A deep understanding of the transmission patterns of L. tropica in the region is necessary for the implementation of effective control measures and a better assessment of the disease burden. In addition, the complexity of this neglected disease requires more fundamental and applied research to unveil potential factors involved in its spread.

Abstract
Both the immature and mature Vicia faba L. seeds are used for human consumption. However, there is a lack of information on the phytochemical composition and the potent biological properties of the immature seeds. The aim of the present study was to establish the profile of bioactive lipids as well as the antibacterial, antioxidant, and α-amylase and α-glucosidase inhibitory capacities of the immature and mature Vicia faba L. seeds. The studied petroleum ether extracts contain different bioactive compounds such as β-sitosterol, lupeol, β-amyrin, α-tocopherol, and γ-tocopherol. The extracts of the immature seeds exhibited higher antioxidant and antibacterial activities than those of mature ones. All tested extracts exerted higher inhibition on α-glucosidase than α-amylase. The immature seeds appeared as promising sources of natural antioxidants, antibacterial compounds, and α-amylase and α-glucosidase inhibitors. Thus, the immature Vicia faba L. seeds have a great potential as functional foods providing health beneficial properties.

Abstract
Leishmaniasis is among the most important emerging vector-borne protozoal disease in terms of disability adjusted life year (DALY'S). The main objectives of this study are, firstly to evaluate the epidemiological situation of Cutaneous Leishmaniasis (CL) from 2000 to 2015 in Moulay Yacoub Province and Fez Prefecture and secondly to analyze the impact of several factors (geographical and socio-economic factors) on the distribution of CL in these provinces. In addition, this study aims to identify the circulating species of Leishmania in order to justify the cause of the case maintenance and to prevent possible epidemics. The spatio-temporal evolution of CL from 2000 to 2015 in the study area revealed the endemic and epidemic character of the disease with a variation in the number of cases according to provinces, and districts. The sharp decrease of cases observed in the study area could be explained by the several control measures that concern the different actors of leishmaniasis. According to the statistical study, the presence of leishmaniasis is mainly related to population movement and environmental conditions. The results of the clinical identification of cutaneous leishmaniasis in the study area showed a diversity of clinical features with the presence of symptoms miming for L. tropica or L. infantum. This result was confirmed by the molecular study PCR-ITS1-RFLP.

Abstract
BACKGROUND In recent decades, there has been a marked increase in the number of reported cases of pertussis around the world, and pertussis continues to be a frequently occurring disease despite an effective childhood vaccination. This study aims to determine the role of household contacts of children diagnosed with pertussis in Casablanca Morocco. METHODS From November 2015 to October 2017, children suspected of whooping cough that consulted Ibn Rochd University hospital at Casablanca with their household contacts were enrolled in the study. Nasopharyngeal (NP) samples of the suspected children were analyzed by culture and RT-PCR. For the household contacts, NP and blood samples were collected and analyzed by RT-PCR and specific detection of pertussis toxin antibodies by ELISA, respectively. RESULTS During the study period, the survey was carried out on 128 infants hospitalized for pertussis suspicion and their families (N = 140). B. pertussis DNA was specifically detected in 73 (57%) samples, coexistence of B. pertussis and B. parapertussis DNA in 3 (2.3%) samples, coexistence of B. pertussis and B. holmesii DNA in 10 (7.81%) and only one (0.78%) sample was IS 481 RT-PCR positive without the possibility of determining the Bordetella species with the diagnostic tools used. Confirmations of Pertussis infection in household contacts by culture, RT- PCR and serology were 10, 46 and 39%, respectively. B. pertussis DNA was confirmed in the infants as well in their mothers in 38% of the cases. Co detection of B. pertussis and B. parapertussis DNA in 2% and co-detection of B. pertussis and B. holmesii DNA in 4%. B. holmesii DNA alone was detected in 5 NP samples of index cases and their mothers. CONCLUSIONS The results of this study confirm that B. pertussis is still circulating in children and adults, and were likely a source of pertussis contamination in infants still not vaccinated. The use of RT-PCR specific for B. pertussis in the diagnosis of adults is less sensitive and should be associated with serologic tests to improve diagnosis of pertussis and contributes to preventing transmission of the disease in infants.

Abstract
Leishmaniases are a group of infectious diseases caused by protozoan Leishmania parasites and are transmitted by the bites of infected phlebotomine sandflies. The heterogeneity of these diseases is influenced by both parasitic properties and host factors. Cutaneous leishmaniasis (CL) is a major public health problem in Morocco, where the geographical expansion of CL (particularly CL caused by Leishmania tropica), the heterogeneous appearance of lesions and the difficulty in diagnosing CL contribute to late diagnosis of CL and delayed treatment of patients. Therefore, the main objective of this study was to describe the epidemiological and clinical profiles of patients with CL diagnosed in Casablanca (Morocco), which is a non-endemic area for CL. A cross-sectional study was conducted between 2010 and 2016, during which epidemiological and clinical data were collected from patients that met the inclusion criteria through an information sheet. Then, samples were obtained from each patient for parasitological and molecular diagnosis, and only patients with positive polymerase chain reaction and genotyping results were included in the study. Overall, 106 cases of CL were genotyped, of which 61 (57.5%) were caused by L. tropica, 38 (35.9%) by L. major and 7 (6.6%) by L. infantum. While all age groups were affected, CL cases wherein L. tropica was the causative agent were most frequently diagnosed in children aged 0–9 years (p = 0.005), whereas those caused by L. major were more frequently diagnosed in elderly patients (p = 0.004). Multivariate logistic regression analysis showed that two clinical variables were significantly associated with CL caused by L. tropica: lesion size (p = 0.002) and occurrence of lesion on the face (p = 0.005). Furthermore, the results of our survey highlighted the association of Leishmania infection when travelling to endemic areas. The high number of endemic foci where patients with CL were infected with L. tropica illustrated the tendency of this form to spread and generate epidemics, exposing young people to a greater degree to the disease. The epidemic status of CL caused by L. tropica in Morocco and the increased movement of the population from rural to urban areas indicate a possible introduction of this species to urban areas.

Abstract
According to the World Health Organization, leishmaniasis remains a major worldwide public health problem. The province of Sefrou located in the center of Morocco is a focus of cutaneous leishmaniasis. The present study aims at evaluating the antileishmanial potential of Berberis sp.,Crataegus oxyacantha, Cistus salviifolius, Ephedra altissima and Lavandula dentatafrequently used by the local population. Methanolic extracts were tested against the promastigote form ofLeishmania tropica, Leishmania majorandLeishmania infantumusing tetrazolium-based colorimetric (MTT) assay. The total phenol and flavonoids content of all extracts were determined using the Folin–Ciocalteu reagent, aluminum chloride, and potassium acetate solutions respectively. The plant extracts exhibited antileishmanial activity with variability depending on the tested strain and the plant species compared to Glucantime® used as control (IC50 (the half maximal inhibitory concentration) > 1,000 μg/mL). The best inhibition was observed with Berberis sp., againstLeishmania major(IC50 = 394.40 ± 3.02 μg/ml), andEphedra altissima(reported for the first time) againstLeishmania infantum(IC50 = 490.84 ± 3.15 μg/mL).Leishmania tropicahas shown the same sensitivity behavior toward the five extracts (in average IC50 = 540 ± 11.20 μg/mL). The total phenolic content was higher forCrataegus oxyacanthaandCistus salviifolius(140.67 ± 3.17 μg eq Gallic Acid (GA)/ mg of Extract (E) and 133.83 ± 9.03 μg eq GA/mg of E respectively), while flavonoid was higher forCistus salviifoliusandLavandula dentata(57.92 ± 2.46 μg eq Quercetin (Que)/ mg of Extract (E) and 41.53 ± 1.74 μg eq Que/mg of E). All the tested extracts present some promising aspects that may cure cutaneous leishmaniasis in the center of Morocco; further bioguided assays are needed to isolate the fractions and the bioactive molecule.

Abstract
Chronic obstructive pulmonary disease (COPD) is a common respiratory disorder. Its exacerbation is infectious in more than half of the cases: with viral priority, while parasitic causes remain exceptional. In this work, we report a case of a COPD exacerbation caused by a visceral leishmaniasis (VL) complicated by a macrophage activation syndrome in an adult living in a Moroccan non-endemic region for this of leismaniasis form. In such atypical clinical feature, the diagnosis of VL was based on the myelogram after presence of peripheral cytopenia. Despite the seriousness of these pathologies, the early and specific treatment of VL allows a quickly improvement in the disorders caused by these diseases.

Abstract
Background Leishmaniases are vector-borne diseases caused by the protozoa of the Leishmania genus. The clinical spectrum of these diseases extends from benign dermal lesions to visceral forms. In the Mediterranean region, zoonotic visceral leishmaniasis (ZVL) is caused by L. infantum. If untreated within two years, the disease usually leads to death. In Morocco, ZVL is endemic in the north, with a hundred cases notified each year, mostly in children aged below five years. Here, we report on two clinical observations in infants presenting unusual concomitant VL and cutaneous leishmaniasis (CL) in Morocco. Case presentation In this case study, we report on two infants aged nine and 12 months old. They both have a history of febrile splenomegaly, anemia, and pallor of mucous membranes. Visceral leishmaniasis was confirmed by parasitological diagnosis (positive bone marrow smear and screening of anti-L. infantum antibodies). However, the clinical examination also showed cutaneous lesions that suggested the presence of CL. This was reinforced by the patients having a history of living or traveling to endemic foci. Thus, direct examination, culture, and PCR-RFLP (ITS1-Hae 3) were carried out on the patients’ dermal exudates. In one of the infants, CL was associated with L. infantum, while in the other it was associated with L. tropica. The infants were treated as according to the recommendations of the Ministry of Health. Both patients were cured in two months; defervescence, reduction of splenomegaly, and healing of cutaneous lesions were all observed. Conclusions These singular patients illustrate the clinical polymorphism of CL and the necessity of updating the differential diagnosis of leukemia-like syndromes, including VL, in children living in or travelling to known endemic areas. These observations suggest a change in the Mediterranean VL phenotype that may be associated with CL.

Abstract
Psoriatic lesions are rarely complicated by recurrent infections. The aim of our study is to determine skin colonisation and nasal carriage of Staphylococcus aureus in patients with psoriasis and in healthy persons. Patients and methods: a comparative study that include 33 patients with psoriasis and 33 healthy persons. Samples were taken from lesional and non lesional psoriatic skin and from healthy skin of control group. For S. aureus nasal carriage, we used sterile cotton tipped swabs. Out of165 samples (66 skin samples and 33 nasal swabs), 26 S. Aureus strains were isolated in 26 persons, 57.69% in the control group and 42.3% in the psoriasisgroup. S. aureus skin colonization was found in one case (3%) inlesional psoriatic skin vs 9 cases (27.3%) in control skin OR=0.08 IC 95% (0.01-0.70) p=0.02 and in 12,1% in non lesional soriatic skin vs 27, 3% in control skin (p =0,13). This colonization was less important in lesional psoriatic skin (3%) than in non lesional psoriatic skin (12.1%) p= 0.20. Nasal screening identified (7/33) 21, 21% S. aureus carriers in psoriasis group and in control group. Our results are in consensus withliterature findings. They have confirmed the importance of antimicrobial peptides in Innateimmunity of human skin. These peptides are normally produced bykeratinocytes in response to inflammatory stimuli such as psoriasis. Their high expression in psoriasis skin reduces the risk of skin infection and skin colonization with S. Aureus.

Abstract
Le but de notre travail est de déterminer le profil des auto-anticorps chez 30 patients ayant un lupus systémique avec ou sans atteinte rénale afin d’établir une corrélation clinico-immunologique entre la néphropathie lupique et ces auto-anticorps. Il s'agit d'une étude transversale de 30 patients atteints de lupus érythémateux systémique diagnostiqués au service de dermatologie durant la période de Décembre 2010 à Décembre 2012 et réalisée conjointement avec le laboratoire d'immunologie. Les anticorps anti-ADN étaient retrouvés chez 17 patients (56.7%) suivis des anti-SSA dans 12 cas (40%). Cinq patients (62.5%) ayant une atteinte rénale avaient des anticorps anti DNA négatifs. Parmi ces patients avec atteinte rénale, 37.5% avaient des anticorps anti SSA sans anticorps anti DNA. La moitié des patients ayant une atteinte rénale (50%) avaient des anticorps anti SSA positifs. Notre série montre l'importance des anticorps anti-SSA surtout chez des patients avec des anticorps anti-DNA négatifs non seulement pour le diagnostic du lupus systémique mais aussi pour déceler certaines manifestations systémiques comme l'atteinte rénale.

Abstract
Background The diagnosis of cutaneous leishmaniasis (CL) might be difficult, in particular in endemic areas where different species of Leishmania can cause lesions of very similar appearance and where other skin diseases with similar clinical symptoms occur. Even today, the parasitological diagnosis of CL remains the gold standard and it is based on the direct identification of amastigotes in microscopy smears and/or culture of promastigotes from infected tissues. Although these techniques are highly specific, they are not sensitive enough. The objective of this study is to contribute to improving the diagnosis of CL and the identification of Leishmania species in Morocco by comparing three PCR-based assays applied directly on dermal samples. Methods A total of 58 patients presenting with cutaneous lesions suggestive of CL were sampled for parasitological diagnosis by direct examination (DE), culture in NNN medium, two kinetoplast DNA (kDNA) PCRs (Lmj4/Uni21 and 13A/13B primers) and one rRNA gene internal transcribed spacer 1 (ITS1) PCR (LITSR/L5.8S primers). The techniques were statistically analyzed and compared. Results According to our consensus positive, 44 out of 58 samples were true positives. The 13A/13B-PCR and ITS1-PCR showed the highest sensitivities (100%). Parasite microscopy and culture detected 43% and 29% of the true positives, respectively, while culture and microscopy together improved sensitivity to 52%. PCRs 13A/13B and ITS1 were associated to four and one false positives, respectively, while the other assays were 100% specific. Furthermore, the ITS1-PCR-RFLP assay clearly identified the Leishmania species for all the true positives (44/44), whereas Lmj4/Uni21-PCR identified 35/44 samples. The comparison between the Leishmania molecular characterizations and the expected species according to the national data from the Ministry of Health indicate 7 discrepant results. Conclusions The PCR-based assays tested on our samples increased the speed and sensitivity of the diagnosis of CL compared to the conventional techniques. Furthermore, we showed that we can not base the species identification on the national data from the Ministry of Health. Finally, we suggest the use of PCR-ITS1-RFLP for diagnosis and simultaneous identification of the species in the Moroccan epidemiological context, but also in similar areas of the Mediterranean Basin.

Abstract
Cutaneous leishmaniasis (CL) in Morocco is caused by three species, Leishmania major, L. tropica and L. infantum. CL has been known in Chichaoua province since 2000. Using DNA extracted from microscopic slides and parasite cultures, collected in the years 2006 and 2009, we identified for the first time L. tropica as the causative agent of CL in this region. Species identification was achieved by performing the ITS1-PCR-RFLP approach. By using this method it was possible to identify parasites in Giemsa stained slides containing less than five parasites per oil-immersion field even they were conserved for up to four months.

Abstract
Dialysis patients are among groups at risk for development of hepatitis C infection (HCV). The aim of the study was to evaluate the prevalence and the incidence of seroconversion for HCV in five haemodialysis units in Morocco. The study was conducted during the period from September 2003 to September 2004. We studied 303 patients (148 females), mean age 49+/-16 years; dialysis duration was higher than five years in 64% of the cases. The prevalence of HCV infection was evaluated by using a fourth generation enzyme immunoassays. In the seronegative patients, we performed anti-HCV tests at three and six months intervals and monthly testing of alanine aminotransferase (ALT) activity and assessment of anti-HCV tests if the ALT activity was elevated. Moreover, risk factors, such as blood transfusion, surgery and other invasive procedures were recorded. Seroprevalence of HCV was 68.3%. Among 85 patients who were tested negative for anti-HCV at the entry of the study, four (4.60%) seroconverted in six month (estimated incidence: 9.41 new cases per year). HCV seropositivity was associated with longer duration of dialysis (p=0.000), and previous blood transfusions (p=0.047). The follow-up of the ALT in the seronegative patients did not show any significant variation. In conclusion, the prevalence and incidence of HCV infection in haemodialysis units in Morocco are dramatically elevated. High incidence seropositivity suggested nosocomial transmission of HCV; the dialysis processes itself, and blood transfusions are important risk factors for HCV transmission in these patients.

Abstract
The morpho-costitutional analysis of 574 urinary lithiasis emitted by tunisean adults permitted to define an épidemiology's profile. This resemble to the épidemiology's profile of under-developed conry: Amore raised frequency of the renal lithiasis at the man than at the woman with a sec ratio of 2.4. An average age of +14 years with a peak to 4th decade in 2 sexes. The upper localitation of the calculi is founded in 94% cases. The fréquency of the relapses, the mode of expulsion and the size of calculi are différent of those published in the litérature. Probably because the time of study which last 4 years is too short, so it don't enable us to find a result like the literature. The surgery is the mode of most fréquent élimination (51%). This s dû to the présence great size calculi in our popûlation and to the récent introduction of the lithotritie in our country.
