Late-onset sarcoidosis: a comparative study

International audienceSarcoidosis is not rare in patients aged more than 65 years, but studies of elderly patients with sarcoidosis are scarce. We analyzed the characteristics and outcomes of patients in a French teaching hospital with late-onset sarcoidosis, defined as sarcoidosis diagnosed in patients aged 65 years or older, and compared them with those of younger patients with sarcoidosis. From 2002 to 2006, 30 patients were identified as having late-onset sarcoidosis and were compared to 70 patients randomly selected aged younger than 65 years. We compared clinical characteristics, laboratory data at diagnosis, severity, therapy, and outcome. The female to male ratio was higher in the late-onset sarcoidosis group than in the younger group (5:1 vs. 1:1, respectively; p = 0.003). Asthenia (30% vs. 10%; p = 0.012), uveitis (33.3 vs. 8.6%; p = 0.002), and specific skin lesions (36.7% vs. 15.7%; p = 0.002) occurred more frequently in patients with late-onset sarcoidosis than in younger patients. On the contrary, asymptomatic chest radiograph abnormalities (p = 0.031) and erythema nodosum (p = 0.016) were not reported in the group of elderly patients. The 2 groups were similar with regard to race, other organ systems involved, pulmonary function, radiographic stage, laboratory values, and severity. The proportion of patients with accessory salivary glands (p = 0.002) and skin (p = 0.023) biopsies was more often contributory to the diagnosis in the late-onset group. After a mean follow-up of 50 months, 1 death related to pulmonary mycetoma and 2 others unrelated to sarcoidosis occurred in the late-onset sarcoidosis group. The 5-year survival rate was 93.3% in the late-onset group compared with 100% in the young-onset group (p = 0.03), while overall mortality was not significantly different. The 2 groups were similar with regard to oral corticosteroid therapy and immunosuppressive use, although steroid-related adverse events were more common in the elderly group. In conclusion, we found certain clinical and diagnostic peculiarities in patients with late-onset sarcoidosis. Asthenia, uveitis, and specific cutaneous lesions were more frequent in this group, whereas erythema nodosum and disclosure on a routine chest roentgenogram were not observed. Biopsy of the minor salivary glands appears to be particularly pertinent for the diagnosis. Evolution and therapeutic management were not different in the 2 groups. However, the patients aged more than 65 years had more side effects related to the corticosteroid therapy

Characteristics of uveitis presenting for the first time in the elderly: analysis of 91 patients in a tertiary center.

International audiencePURPOSE: To describe uveitis clinical characteristics in the elderly. METHODS: Retrospective review of 91 patients at the age of 60 or more years at the authors' uveitis tertiary center over a 7-year period. RESULTS: Uveitis in the elderly accounted for 30.1% of this population. Uveitis localization was anterior in 22.0% of patients, intermediate in 8.8%, posterior in 20.9%, while 41.7% patients presented with panuveitis. Sarcoidosis (37.4%) and idiopathic uveitis (36.3%) accounted for the majority of cases, whereas other diagnostic entities accounted for 26.3%. Panuveitis (41.7%) and sarcoidosis (37.4%) were detected at a significantly higher frequency than in the younger population. Contrarily, ankylosing spondylitis and established ophthalmological entities (pars planitis, Birdshot chorioretinopathy, Fuchs heterochromic cyclitis) were more common in patients younger than 60 years old. CONCLUSION: In the authors' experience, sarcoidosis is the leading cause of uveitis in the elderly. Idiopathic uveitis and other specific entities account for less than two-thirds of cases

Immune thrombocytopenia with clinical significance in systemic lupus erythematosus: a retrospective cohort study of 90 patients.

International audienceObjectives: To describe the characteristics, treatment, and outcome of patients with immune thrombocytopenia with clinical significance (ITPCS) associated with systemic lupus erythematosus (SLE).Methods: This retrospective multicentre study included SLE patients who experienced ≥1 ITPCS (defined as ITP with attributable bleeding disorders and/or a platelet count 8 and/or WHO score>2.Results: A total of 90 patients were included, the median (range) follow-up duration was 80 (6-446) months. ITP was diagnosed before SLE in 25 patients. They presented high rate of autoimmune haemolytic anaemia (15%), antiphospholipid antibody (62%), and antiphospholipid syndrome (19%). The 25 (28%) patients who experienced MBG had significantly more bleedings at ITP diagnosis and higher bleeding scores, and serositis and thrombosis during follow-up. They required significantly more treatment lines, transfusions, and hospitalizations. The 11 (12%) patients who experienced no bleeding event presented a significantly more restricted SLE phenotype (cutaneous and/or articular). Patients received a mean (range) of 4.2 (1-11) treatment lines. Corticosteroids and hydroxychloroquine allowed ITPCS overall response in one third of patients. The median relapse-free survival of rituximab (n = 34), azathioprine (n = 19), mycophenolate mofetil (n = 8), thrombopoietin-receptor agonists (n = 16), and splenectomy (n = 19) were 53, 31.5, 61, 24.5, and 78 months, respectively. Four patients experienced thrombotic events after splenectomy and one occurred under thrombopoietin-receptor agonist treatment.Conclusion: SLE-ITCS patients displayed a high rate of haematological abnormalities and MBG patients exhibited higher morbidity. Management of thrombocytopenia was highly heterogeneous and many options seem viable

Kawasaki disease in adults: observations in France and literature review Short title: Kawasaki disease in adults in France

International audienceObjective Kawasaki disease (KD) is a vasculitis that mostly occurs in young children and rarely in adults. We analyzed the characteristics of adult-onset KD (AKD) in France. Methods We collected retrospective and prospective data for patients with a diagnosis of KD occurring after the age of 18 years. Cases were obtained via various French medical networks and identified from the international literature. Results We included 43 patients of AKD at 26 institution from 1992 to 2015, with mean (SD) age 30 (11) years (range 18–68) and sex ratio (M/F) 1.2; 34 patients met the American Heart Association criteria and 9 were incomplete AKD. The median time to diagnosis was 13 days (interquartile range 8–21). The main symptoms were fever (100%), exanthema (98%), changes in the extremities (91%), conjunctivitis (77%), oral cavity changes (89%), cervical adenitis (55%) and cardiac abnormalities (45%). Overall, 35% of patients showed large-vessel vasculitis: coronary vasculitis (26%) and coronary aneurysm (19%). Treatment was mostly intravenous immunoglobulins (79%) and aspirin (81%). Four patients showed myocardial infarction due to coronary vasculitis, but none were treated with IVIg because of late diagnosis. After a median follow-up of 5 months (range 1–117), persistent aneurysm was noted in 9% of cases. Damage was significantly lower with early treatment than late or no treatment (p = 0.01). Conclusion Given the high frequency of cardiac involvement and complications in this series of AKD, diagnosis and treatment should not be delayed, and early IVIg treatment seems to improve the outcom
