RESUMO

BACKGROUND: Checkpoint inhibitors are first-line therapies in melanoma, but safety in older adults has not yet been assessed. Ipilimumab improves survival, but immunologic-related adverse events (AEs) can be threatening, and its use in elderly people raises questions. AIM: To assess safety in a cohort of very elderly patients treated with ipilimumab. METHODS: All patients over 80 years treated with ipilimumab for melanoma were retrospectively included. AE occurrence, management, and outcome, as well as response rate at week 16 and overall survival were recorded, and compared to data for a group of younger patients treated in our institution during the same period. RESULTS: In the elderly group, 23 patients were included with a median age of 82 years [80-90]. AEs amounting to 23 occurred in 15 patients (65%) with 5 grade 3 (22%) and 1 grade 5 (opportunistic infection) AEs. Corticosteroids were required for five (22%) patients, additive immunosuppressive therapy for two, hospitalization for four, and definitive interruption of ipilimumab for three. Median overall survival was 14 months. In the younger group, 29 patients were included with a median age of 58 years. AEs occurred in 15/29 (52%) with 4 grade 3 (19%) and 1 grade 4 (7%). Median OS was 17 months. CONCLUSION: Serious AEs occurred in 80 + adults at the same rate as observed in our younger patients and as previously reported in younger populations. Ipilimumab can be an option in elderly patients, as patients may benefit from therapy and safety seems to be manageable.

RESUMO

BACKGROUND: Skin pigmentation disorders in systemic sclerosis (SSc) have been sparsely described in the literature. Nevertheless, they could be a diagnostic and/or severity marker. OBJECTIVES: To assess the association between pigmentation disorders and systemic involvement in patients with SSc. METHODS: A total of 5 patterns of skin pigmentation disorders were defined: diffuse hyperpigmentation; hyperpigmentation of sun-exposed areas; hypopigmentation of the head, neck, and/or upper part of the chest; acral hypopigmentation; and diffuse hypopigmentation. RESULTS: A total of 239 patients were included; 88 patients (36.8%) had skin pigmentation disorders as follows: diffuse hyperpigmentation and hyperpigmentation of sun-exposed areas in 38.6% (n = 34) and 27.3% (n = 24) of patients, respectively; hypopigmentation of the face, neck, and/or chest in 10.2% of patients (n = 9); diffuse hypopigmentation in 12.5% (n = 11); and acral hypopigmentation in 17% (n = 15). Diffuse hyperpigmentation was associated with diffuse SSc (P = .001), increased modified Rodnan skin score (P = .001), and shorter duration of Raynaud phenomenon (P = .002) in univariate analysis but not in multivariate analysis. Moreover, diffuse hyperpigmentation was associated with digital ulcers (P = .005), as confirmed by multivariate analysis (odds ratio, 2.96; 95% confidence interval, 1.28-6.89). LIMITATIONS: This was a single-center retrospective study of a cohort of patients with SSc. CONCLUSION: Screening for skin pigmentation disorders could be useful in the management of patients with SSc to identify those with a high risk of development of digital ulcers, which is a symptom of vascular involvement in SSc.

RESUMO

Systemic sclerosis (SSc) is a rare and severe connective tissue disease combining autoimmune and vasculopathy features, ultimately leading to organ fibrosis. Impaired angiogenesis is an often silent and life-threatening complication of the disease. We hypothesize that CCN3, a member of the CCN family of extracellular matrix proteins, which is an antagonist of the profibrotic protein CCN2 as well as a proangiogenic factor, is implicated in SSc pathophysiology. We performed skin biopsies on 26 patients with SSc, both in fibrotic and nonfibrotic areas for 17 patients, and collected 18 healthy control skin specimens for immunohistochemistry and cell culture. Histological analysis of nonfibrotic and fibrotic SSc skin shows a systemic decrease of papillary dermis surface as well as disappearance of capillaries. CCN3 expression is systematically decreased in the dermis of patients with SSc compared with healthy controls, particularly in dermal blood vessels. Moreover, CCN3 is decreased in vitro in endothelial cells from patients with SSc. We show that CCN3 is essential for endothelial cell migration and angiogenesis in vitro. In conclusion, CCN3 may represent a promising therapeutic target for patients with SSc presenting with vascular involvement.
