RESUMO

Systemic Lupus Erythematosus (SLE) is a complex autoimmune disease with a high female predominance. To date, studies about SLE in Morocco are few. This retrospective study describes the clinical and immunological features in a series of 50 SLE Moroccan patients in University Hospital Center of Rabat, Morocco, between December 2011 and December 2013. All patients were screened for antinuclear antibodies (ANA) and anti-DNA antibodies by indirect immunofluorescence, followed by identification of anti-extractable nuclear antigen antibodies by ELISA. The female to male ratio was 6.1:1. Mean age was 31.72 years. The main clinical manifestations were arthritis (82%), mucocutaneous manifestations (80%), renal manifestations (50%), and hematological features (46%). Of the mucocutaneous features, the highest frequencies were observed in the malar rash (68%) and photosensitivity (60%). Of the hematological features, lymphopenia was most frequently observed in 30% of patients, followed by hemolytic anemia in 16% and leucopenia and thrombocytopenia in 8%. Central nervous system was involved in 10%. ANA were found in 88%, anti-DNA antibodies in 56%, and anti-Sm antibodies in 50%. Anti-SSA, anti-SSB, anti-Sm/RNP, and anti-Scl70 antibodies were detected in 38%, 10%, 48%, and 8%, respectively. Our data show that, in our patients, the main clinical and immunological features of SLE remain comparable to patients from other Arab countries.

RESUMO

The chemical composition of the essential oil produced by steam distillation of the inflorescences of naturally growing Anacamptis coriophora (L.) R. M. Bateman, Pridgeon & M. W. Chase subsp.fragrans (Pollini) R. M. Bateman, Pridgeon & M. W. Chase (Orchidaceae) from Kroumiria, north-west Tunisia was studied by GC-MS, which led to the identification of 19 volatile components, representing 97% of the oil. The main constituents were methyl-(E)-p-methoxycinnamate (29.3%), 13-heptadecyn-1-ol (18.6%), 2,5-dimethoxybenzyl alcohol (14.1%) and 4-(1,1,3,3-tetramethylbutyl)-phenol (9.0%). DPPH radical scavenging revealed a weak antioxidant activity. In addition, the antiproliferative effects were evaluated on BxPC3 human pancreatic carcinoma cells and on 2008 human ovarian cancer cells showing significant effect. This is the first report of the chemical composition of essential oils obtained from A. coriophora subsp. fragrans inflorescences for North Africa. Further studies are needed to understand fully the possible mechanism of action behind the cytotoxic activity of the essential oil.

RESUMO

The essential oil extracted from Desfontaine's rupturewort, Herniaria fontanesii J. Gay subsp. fontanesii growing wildly in Tunisia, was analyzed using GC and GC-MS techniques. The free radical scavenging capacity and total phenol contents of three crude extracts having different polarities (n-hexane, ethyl acetate and methanol) were examined. Thus, a total of 35 constituents were identified in the Desfontaine's rupturewort essential oil representing 89.8% of the whole constituents. The oil was dominated by hexadecanoic acid, caryophyllene oxide, terpin-4-ol, khusimone and trans-sabinene hydrate. The total phenolic contents ranged from 16.91 to 92.27 mg of gallic acid/g of dry weight and they were found to be significantly higher in methanol than in polar ethyl acetate and hexane extracts. Correlations were observed between the phenolic contents and the antioxidant properties. Thus, the antioxidant activity of the methanol extract was superior to that of all samples tested (IC50 = 0.21 ± 0.04 mg/mL).

RESUMO

The chemical composition, antioxidant, cytotoxic and antiviral activities of the essential oil obtained by hydrodistillation from the aerial parts of Teucrium pseudochamaepitys (Lamiaceae) collected from Zaghouan province of Tunisia are reported. The essential oil was analyzed by gas chromatography equipped with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Thirty-one compounds were identified representing 88.6% of the total essential oil. Hexadecanoic acid was found to be the most abundant component (26.1%) followed by caryophyllene oxide (6.3%), myristicin (4.9%) and α-cubebene (3.9%). The antioxidant capacity of the oil was measured on the basis of the scavenging activity to the stable 2,2-diphenyl-1-picrylhydrazyl (DPPH). The IC50 value of the oil was evaluated as 0.77 mg·mL(-1). In addition, the essential oil was found to possess moderate cytotoxic effects on the HEp-2 cell line (50% cytotoxic concentration (CC50)=653.6 µg·mL(-1)). The potential antiviral effect was tested against Coxsackievirus B (CV-B), a significant human and mouse pathogen that causes pediatric central nervous system disease, commonly with acute syndromes. The reduction of viral infectivity by the essential oil was measured using a cytopathic (CPE) reduction assay.

RESUMO

The objectives of this study were to chemically characterise and evaluate the antioxidant potential of the essential oil from Teucrium flavum L. subsp. flavum growing spontaneously in Tunisia. The volatile oil was extracted by hydrodistillation of the aerial parts in a Clevenger type apparatus. Forty constituents were identified via GC and GC-MS analysis. ß-caryophyllene (32.5%) and α-humulene (17.8%) were the most abundant components. The evaluation of free radical scavenging activity using stable DPPH free radical showed that the volatile oil exhibits a moderate antioxidant activity and reduces DPPH to 50% at EC50 value of 1230 µg mL(-1).

RESUMO

Research has demonstrated that strict adherence is necessary to maximize highly active antiretroviral therapy (HAART) benefits. This is particularly challenging for low-literacy populations in resource-limited settings like Morocco and motivated the implementation of a psychoeducative program for patients under HAART at Rabat University Hospital. The study aimed at assessing the program's impact on adherence to antiretroviral medication, knowledge of HIV/AIDS and HAART, quality of life, and biological parameters. It included patients under treatment for at least 2 months that benefited from 3 to 5 educational and psychological support sessions. Data were collected at baseline, 3 and 6 months. In all, 50 patients were included. The mean age was 38 years; 52% were illiterate and 62% unemployed. Adherence scores were high at baseline (98%) and showed no significant change throughout the study. Knowledge of HAART and HIV/AIDS, and quality of life improved significantly both at months 3 and 6. Significant increase for CD4 count rates and decrease for viral load rates were also reported. The program had no significant impact on adherence but substantively developed patients' knowledge of HIV/AIDS and HAART and improved their quality of life.

RESUMO

The aim of the present study was to describe a case of Behçet's disease revealed by a recurrent meningitis and to review literature on these two conditions. We describe the case of a 25-year-old man who presented four episodes of recurrent meningitis without any locoregional cause and developed oral and genital ulcerations few months later. Behçet's disease is a chronic, multisystemic disorder with variable prevalence in different geographical areas. Its neurological manifestations are well recognized. Both central and peripheral nervous systems can be involved. Recurrent meningitis in Behçet's disease is exceptional. To our knowledge, only two cases reported recurrent meningitis as initial manifestation of Behçet's disease. This case report underscores another facet of neurological manifestations of Behçet's disease.
