Outcome of refractory to conventional and/or biologic treatment adult Still's disease following canakinumab treatment: Countrywide data in 50 patients.

OBJECTIVE: To assess the efficacy and safety of the IL-1b inhibitor canakinumab in all adults with refractory Still's disease identified from the National Organization For Medicines for off-label drug use. METHODS: In a retrospective longitudinal multicenter cohort of 50 patients (median age 39 years) with active Still's disease despite treatment with corticosteroids (n = 11), conventional and synthetic (n = 34) and/or biologic disease modifying anti-rheumatic drugs (n = 30), we assessed the efficacy of canakinumab 150-300 mg administered every 4 (n = 47) or 8 weeks (n = 3) as combination therapy or monotherapy (n = 7) during a median follow-up of 27 (3-84) months. RESULTS: Α complete response was initially observed in 78% of patients within 3 months (median), irrespective of age at disease onset. A partial response was evident in 20%. One patient had resistant disease. Treatment de-escalation was attempted in 15 of 39 complete responders and a complete drug discontinuation in 21 patients for 8 months (median). Eleven patients (22%) relapsed during treatment, one during de-escalation process, and 11 after treatment discontinuation. Overall, 9 of 11 relapses were successfully treated with canakinumab treatment intensification or re-introduction. At last visit, 18% of patients were off treatment due to remission and 26% due to disease activity. Canakinumab had a significant corticosteroid sparing effect allowing weaning in 21 of 41 cases. Infections (20%, severe 4%) and leucopenia (6%) led to treatment cessation in one patient. CONCLUSION: High rates of sustained remission were observed in this, largest so far, real-life cohort of adult patients with refractory Still's disease treated with canakinumab.

Clinical expression and course in patients with late onset systemic lupus erythematosus.

BACKGROUND: To analyze the pattern of clinical expression and the 5-year disease course in Caucasian patients with late onset of systemic lupus erythematosus (SLE) and to compare the findings with an early onset SLE group. METHODS: Medical records of 551 patients who presented with SLE at hospitals of the region of Thessaloniki between 1989 and 2007 were studied. Patients who developed SLE at or after the age of 50 years were classified as the late onset group, while younger patients served as the early onset group. Data on clinical manifestations and damage accrual at disease onset and at 5 years was obtained and compared between the two groups. RESULTS: In 121 patients, the disease started after the age of 50 years. Elderly patients showed less pronounced female predominance and less often presented with malar rash, nephropathy, fever and lymphadenopathy, while lung involvement, pericarditis and sicca syndrome were more frequent. Damage accrual was similar in both groups. The main causes of damage at 5 years differed, with the elderly exhibiting more cardiovascular damage. They also had a higher incidence of hypertension and osteoporosis at 5 years. CONCLUSIONS: Caucasian SLE patients with late onset of the disease present with different clinical manifestations, suggesting that age affects the expression of SLE. Damage accrual at 5 years is similar in the elderly and the younger patients. However, the causes of this damage and the occurrence of other comorbidities follow a different pattern, possibly reflecting the disease process and the effects of aging.
