Background: Remission is the most desirable target in the treatment systemic lupus erythematosus (SLE) however, a universally accepted definition of remission in SLE is still missing. Objectives: To test the contribution of the different items included into the currently used definitions of remission in SLE. Methods: We studied 646 Caucasian patients from a multicentre lupus cohort followed for at least 5-years: female 585 (90.6%), mean age at baseline 40.59±12.14 years, mean disease duration 9.18±6.86 years. Disease activity was assessed by clinical SLE Disease Activity Index 2000 (cSLEDAI) and SELENA-SLEDAI physician global assessment (PGA), and damage by Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI). To test the performance of the different items included in the definitions of SLE remission [1, 2] we identify 7 subtypes of remission: (1) PGA (0-3) Results: The number of patients achieving remission according to the different definitions is show in Figure 1. The proportion of patients who maintained prolonged remission (5-consecutive years) was: PGA When PGA Conclusion: The prevalence and extent of damage significantly decreased as the time spent in remission increased, irrespective of the remission subtype.

Adipokines discovery opened a new research field that investigates the interface and the relationship between immune response, nutrition, and metabolism. Leptin is the first adipokine discovered and exerts a wide spectrum of biologic function such as control of food intake and energy expenditure, modulation of insulin sensitivity, regulation of neuro-endocrine system and activation of immunity. Leptin involvement is described in many autoimmune diseases. In SLE, leptin seems playing a complex role, linking metabolic syndrome, atherosclerosis, and autoimmune disease activity.

The difficulty in identifying, differentiating and expressing emotions is a neuropsychological condition called alexithymia. During the last years it has grown the interest of scientific community for alexithymia, in particular in2 chronic conditions. Crescent literature data demonstrated that a considerable number of SLE patients present difficulty not only in identifying, differentiating, and articulating emotions but also in differentiating them from bodily sensations, configuring the alexithymia complaint. Alexithymia seems to be not related to SLE disease activity but tightly related to mood states. Identify proper pharmacological and psychological approach to alexithymia in SLE patients is a major challenge for future research.
