Disease activity score for still's disease.

Objective: To develop the Still's Disease Activity Score (SDAS).

Methods: We used data from the prospective adult-onset Still's disease cohort study and evaluated the disease activity. An expert group selected the most frequent, reproducible, and objective variables significantly modified in statistical analysis when comparing patients in the active group and in the remission group.

Immunomodulatory effect of vitamin D supplementation on Behçet's disease patients: effect on nitric oxide and Th17/Treg cytokines production.

Introduction: In the last decade, an immuno-modulatory effect of vitamin D supplementation have emerged as a potential therapeutic approach for some inflammatory and autoimmune diseases. As previously reported, vitamin D deficiency was strongly linked to several diseases as Behçet's disease (BD). BD is a chronic systemic inflammatory disorder with autoimmunity, genetic and environmental factors involvement.

Proposal of a new diagnostic algorithm for adult-onset Still's disease.

Objective: This study was performed to develop a new diagnostic algorithm for adult-onset Still's disease (AOSD).

Methods: We conducted a multicenter prospective nationwide case-control study in tertiary Internal Medicine, Rheumatology, and Infectious Diseases departments, to include successively patients with suspected AOSD based on the presence of two or more major criteria of Yamaguchi and/or Fautrel classifications. Patients were classified as AOSD or controls according to a predefined procedure.

Validation of the neutrophil-to-lymphocyte ratio as a new simple biomarker of adult onset Still's disease: A STROBE-Compliant prospective observational study.

This study was performed to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of adult onset Still disease (AOSD) and its performance to improve the sensitivity of the classifications criteria (Yamaguchi and Fautrel Classifications). We conducted a multicenter prospective nationwide case-control study in Internal medicine, Rheumatology and Infectious disease departments, to include successively patients with suspected AOSD (2 or more major criteria of Yamaguchi or Fautrel classifications). All clinical and biological features were collected in a consensual and standardized clinical assessment at baseline and during follow-up.

Increased Salivary Cytokines and Nitric Oxide Levels in Behçet's Disease: Interleukin-32, a Novel Player in Disease Prognosis.

Background: Oral aphthosis is one of the major manifestations of Behçet's disease (BD), a chronic, multisystemic vasculitis. BD etio-pathogenicity related to oral health lack.

Objective: This study investigated the possible relationships between poor oral hygiene, oral activity, disease severity and saliva's Interleukin (IL)-32, IL-6, IL-10 and nitric oxide (NO) levels in Behçet's patients to determine their role in disease prognosis and their potential therapeutic interest.

Vitamin D status in Algerian Behçet's disease patients: an immunomodulatory effect on NO pathway.

Behçet's disease (BD) is an inflammatory multisystemic disorder associated with orogenital ulcers, uveitis and skin lesions with unpredictable episodes of exacerbations and remissions. Even though several immunological and environmental factors contribute to BD progression, its ethiopathogenesis remains uncertain and elusive. Considered as one of the potent environmental factors that can increase prevalence of some autoimmune and inflammatory disorders, vitamin D deficiency has been linked to several diseases as BD.

Cytokines Modulate the "Immune-Metabolism" Interactions during Behçet Disease: Effect on Arginine Metabolism.

Aim and Methods. In this study, we evaluated NOS and arginase activities and their regulation during Behçet disease, a systemic chronic inflammatory disorder with uncertain etiology. The peripheral blood mononuclear cells of 36 patients and 15 control samples (PBMC) were cultured in either RPMI 1640, MEM, or DMEM complemented with 10% of FBS and antibiotics.

Ex vivo immunomodulatory effect of all-trans-retinoic acid during Behçet's disease: a study in Algerian patients.

Uveitis, recurrent oral and genital ulcerations associated with skin lesions are the major symptoms of a chronic multisystemic inflammatory disorder known as Behçet's disease (BD). High prevalence of this dreaded disease has been observed in the Mediterranean basin, including Algeria and along the Silk Road. Although the etiologic agent of this disease remains uncertain, many hypotheses have been advanced in its pathogenesis.

Ex vivo effects of flavonoïds extracted from Artemisia herba alba on cytokines and nitric oxide production in Algerian patients with Adamantiades-Behçet's disease.

Background: Adamantiades-Behçet's disease (ABD) is a chronic multisystemic inflammation with unknown pathophysiology. This disorder is associated with a dysregulation of the cytokine network that hyperactivates neutrophils and macrophages. In this study, we investigate the modulatory effects of flavonoïd compounds extracted from Algerian medicinal plant Artemisia herba alba on Th1 and Th2 cytokines and nitric oxide production.
