Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpose of this study is to assess the effect of smoking status on the success of Etanercept therapy in patients with moderate-to-severe psoriasis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study hypothesis was based on the following rationale:

* Psoriasis vulgaris is a chronic inflammatory skin disease with several extracutaneous manifestations and significant comorbidities (among others cardiovascular disease, metabolic syndrome, obesity and depression).
* An increased prevalence of smoking among psoriasis patients, as compared with healthy subjects, has been observed in several studies
* More recent studies suggest that cigarette smoking may trigger the development of psoriasis through oxidative, inflammatory and genetic mechanisms.Furthermore, smoking is associated with the clinical severity of psoriasis
* Smoking also contributes to higher morbidity and mortality from smoking related disorders in these patients There is now some evidence that patients with psoriasis who smoke tend to be less responsive to treatment

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1: smokers patients group

smokers (more than 10 cigarettes per day)

QUESTIONNAIRE ON SMOKING HABITS

Intervention Type BEHAVIORAL

Data on smoking will include the age at which cigarette smoking began and ceased and the average amount smoked daily. Intensity (number of cigarettes smoked per day), duration of smoking (years), and time since cessation (years) will be categorized. Also, the smoking status of the patient prior psoriasis diagnosis will be assessed (smoker or non-smoker and years of smoking prior to psoriasis diagnosis).

Smoking habit evaluation: baseline and changes in smoking habit at 12 and 24-weeks follow-up time points.

Group 2 : non-smokers patients group

Smoking status will be classified as current and never/former. Former smokers will be defined as those who had stopped smoking at least 1 year before being interviewed for this study
