Addictive behaviors, cardiovascular and metabolic comorbidities in North African psoriatic patients: case-control study.

We propose to study the epidemiological aspects of North African psoriasis and determine the cardiovascular comorbidities and addictive behaviors associated with psoriasis. This is a North African case-control study which was conducted over a five year period (October 2008 through August 2013), involving 671 psoriatic patients and 1,242 controls identified in various Algerian, Tunisian and Moroccan university hospitals. For each patient, epidemiological characteristic, addictive behaviors, and cardiovascular pathologies associated with psoriasis were noted. Six hundred and seventy one psoriasis patients and 1,242 controls were included in this study. The average age was 47.24 years and the M/F sex-ratio was 1.11 (354 men and 317 women). Statistical analysis showed that psoriasis patients were more likely to develop addictive behaviors than controls (smoking p<10-5 and alcohol consumption: p < 10-5), together with dyslipidemia (30.1% of patients p < 10-5), obesity (23.8% of patients p < 10-4), hypertension (22.3% of patients p < 10-5), diabetes (21.7% of occurrences p < 10-5) and metabolic syndrome (37.4% of patients p<10-5). The relative risk for developing psoriasis was 1.9 in hypertensive patients, 1.7 in diabetic patients, 3.9 in dyslipidemic patients, 1.8 in obese patients, 2.6 in those with metabolic syndrome, 2.1 in smokers and 2.8 in alcoholics. Our work confirms the high incidence of addictive behaviors and of cardiovascular and metabolic comorbidities during the North-African psoriasis, hence the need for a multidisciplinary comprehensive care based on a guideline suited to the characteristics of North-African psoriatic patients.

Psoriasis and Staphylococcus aureus skin colonization in Moroccan patients.

UNLABELLED: 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 of 165 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 psoriasis group. S. aureus skin colonization was found in one case (3%) in lesional 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 psoriatic 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 with literature findings. They have confirmed the importance of antimicrobial peptides in Innate immunity of human skin. These peptides are normally produced by keratinocytes 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.

[Port wine stains and Pulsed Dye Laser: study of prognostic factors in 74 Moroccan patients]. / Angiomes plans et laser à colorant pulsé: étude des facteurs pronostiques dans une série marocaine de 74 cas.

Pulsed dye laser (LCP) is currently the gold standard for Port wine stains (PWS) treatment. However, predictive clinical criteria indicating a right or poor response are not yet clear in our context. This study aims to determine the factors associated with poor/good response in Moroccan patients with PWS treated with LCP. We conducted a retrospective study of patients treated for PWS at the dermatology department at the CHU Ibn Rochd in Casablanca between January 2008 and December 2013. We collected the following clinical parameters: age, sex, location, history, parameters used, number of sessions, phototype and physician satisfaction with outcome of the bleaching therapy. A good response was defined by the achievement of 50% lesional lightening at the end of the 6th session. Patients were contacted by telephone to measure their satisfaction. These results were correlated with the clinical parameters mentioned above. We set our significance level at 0.05. Seventy-four patients were eligible The female sex represented 69% and the median age was 18 years. It occurred predominantly on the face (94%). The comparative study of good/poor responders showed that the mean age in the group of good responders was lower than that of poor responders with a significant difference (p = 0.047). The number of sessions in the group of good responders was higher (p = 0.044). The parameters were variable from one patient to another. There was no difference in the type of skin between the two groups. The best bleached location was the area V2. This study showed that patients undergoing several PWS treatment sessions at a young age had a superior therapeutic response in our context. This highlights the role of early diagnosis and short interval management to improve outcomes and minimize adverse effects.

Cutaneous sarcoidosis simulating porokeratosis of Mibelli.

We report a skin localization of systemic sarcoidosis, which presented with lesions that resemble porokeratosis of Mibelli. Skin biopsy showed non-caseating sarcoidal granuloma. Whereas cutaneous sarcoidosis is present in up to one-third of cases and may present with a wide variety of lesions, our presentation is uncommon. Partial remission was obtained with hydroxychloroquine and prednisone.

EPIMAG: International Cross-Sectional Epidemiological Psoriasis Study in the Maghreb.

BACKGROUND: Psoriasis is a common skin disorder that is characterized by red plaques covered with silvery scales and is associated with considerable psychosocial impact. It has been described in several studies worldwide, but specific data from the Maghreb (Algeria, Morocco and Tunisia) are unavailable. OBJECTIVES: To characterize the frequency of new psoriasis cases and to describe the epidemiological and clinical profile of psoriasis in the Maghreb. METHODS: A psoriasis working group for the Maghreb initiated the EPIMAG international multicentre cross-sectional observational epidemiological study coupled with a 2-week psoriasis screening study via medical consultation. Data were collected via questionnaires. RESULTS: The total analysis population included 373 pre-existing and 326 new psoriasis cases, described by 261 participating investigators. The frequency of new psoriasis cases was 10.26/1,000 in Algeria, 15.04/1,000 in Morocco and 13.26/1,000 in Tunisia, and thus 12.08/1,000 in the Maghreb. In all 699 psoriasis subjects, the mean age was 46 years, the mean BMI was 26.6, and 55.7% of subjects were men. Two thirds of the subjects had never smoked, and 85.0% had never consumed alcohol. Half had brown skin, and 28.6% had a family history of psoriasis. Three quarters had localized psoriasis, 85.8% had plaque psoriasis, coupled with pruritus in over 70.0% of cases. Flares or outbreaks were most often triggered by stress (79.4%) and change of season (43.1%). The majority of subjects used topical therapy, and the investigators considered overall treatment efficacy to be partial in over half of the cases. Among patients with pre-existing psoriasis, secondary analyses showed that 73.2% had severe psoriasis, and that quality of life was severely affected in 40.1% of cases. The mean number of missing school or work days over 6 months was 3.2 (±12.1) days. CONCLUSIONS: Our study provides novel information relative to psoriasis epidemiology and characterization in the Maghreb and highlights the need to improve psoriasis screening and management in the region. The data will help optimize psoriasis management, to ensure appropriate national health care policies.

Nail changes in connective tissue diseases: a study of 39 cases.

The objective is to identify nail unit changes associated with connective tissue diseases (CTD) and evaluate their frequency. We carried a prospective study between March 2012 and March2013 in our department. All patients with CTD were included. A clinical examination of the fingernails was done by the same dermatologist. Nail features were noted and classified and photos taken. Thirty nine patients were enrolled including: 16 systemic sclerosis, 14 lupus erythematosus (SLE), 8 dermatomyositis (DM), 1 primary Sjorgen's syndrome. The mean age was 40 years old. The mean duration of the disease was 6 years. Nail unit changes were present in 27 patients (69%). The abnormalities observed were Longitidunal ridging in 11 patients, Peri ungueal erythema in 10 patients, Peri-ungual telangiectasia in 11 patients, Ragged cuticle in 10 patients fingertips scars in 9 patients, Increase of longitudinal curvature and beaking of the nail in 4 patients, Increase in transverse curvature in 4 patients, dyschromia of the proximal nail fold in 3 patients, Subungual hyperkeratosis in 3 patients, onycholysis in 2 patients, splinter haemorrhages in 3 patients, nail plate pigmentation in 2 patients, pseudoclubbing in 1 patient, macrolunula in 1 patients, Red lunulae in one patient, bluish-black discoloration of the nail plate in one patient. The proximal nailfold was found to be most sites affected.
