Methods: The cutaneous capillary lymphatic system in patients with systemic sclerosis was investigated using fluorescence microlymphography. The distal upper limbs of 16 healthy controls (mean age 62.3+/-13.1 yr) and 16 patients with systemic sclerosis (mean age 58.9+/-13.6 yr) were examined and the following parameters were evaluated: (a) single lymphatic capillaries; (b) lymphatic capillary network and cutaneous backflow; (c) extension of the stained lymphatics; (d) diameter of single lymphatic capillaries.

Results: At the finger level, lymphatic capillaries were lacking in five patients, while they were present in all controls (P < 0.05). Extension of the stained lymphatics was increased in 11 patients (8.1+/-6.0 mm) compared to the 16 healthy controls (2.0+/-1.2 mm) (P < 0.0001). Cutaneous backflow was observed in three patients (P < 0.05). At the hand level, lymphatic network extension was significantly different between patients (3.8+/-2.4 mm) and controls (1.2+/-0.8 mm) (P < 0.01); however, no significant differences were found at the forearm level.

Conclusion: Lesional skin in patients with systemic sclerosis exhibits evidence of lymphatic microangiopathy.

The aims of this study were to investigate the prevalence of cryofibrinogenemia in a cohort of patients with systemic sclerosis (SSc) regardless of clinical manifestations, who were admitted to our hospital and determine the associations among CF positivity, disease features and ongoing therapies. This was a monocentric and retrospective study. The inclusion criteria were a diagnosis of SSc (according to the ACR/EULAR 2013 classification criteria), regular administration of i.

Background And Objectives: Neurosarcoidosis poses a diagnostic and management challenge due to its rarity, phenotypic variability, and lack of randomized controlled studies to guide treatment selection. Recommendations for management based on expert opinion are useful in clinical practice and provide a framework for designing prospective studies.

Methods: In this Delphi survey study, specialists with experience in managing patients with neurosarcoidosis were invited to anonymously complete 2 surveys about key elements of evaluation, diagnosis, treatment, monitoring, and long-term management of neurosarcoidosis.

Objectives: Patients' outcomes and experiences can be affected by rheumatologist knowledge and awareness of systemic sclerosis (SSc). Our survey, directed at UK-based rheumatologists, aimed to expand our understanding of the above points along with their ability to keep up to date with guidelines defining best practice.

Methods: Rheumatologists were invited to participate in an online survey, with the results analysed and presented descriptively and graphically by SRUK.
