CXCL13 is an activity marker for systemic, but not cutaneous lupus erythematosus: a longitudinal cohort study.

Serum levels of the IFN-regulated cytokine CXCL13 have been found to correlate with SLEDAI and renal involvement in systemic lupus erythematosus. This study investigates whether CXCL13 can also be a marker of disease activity in patients with subacute cutaneous or chronic cutaneous lupus erythematosus (SCLE, CCLE). We analysed CXCL13 levels in 60 patients' sera (18 SLE, 19 SCLE, 23 CCLE) at five time points within 1 year and correlated these levels with disease activity scores and laboratory markers.

European Dermatology Forum S1-guideline on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: localized scleroderma, systemic sclerosis and overlap syndromes.

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present guideline focuses on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis.

Changes in pulmonary exercise haemodynamics in scleroderma: a 4-year prospective study.

Pulmonary arterial hypertension (PAH) is a feared complication of systemic sclerosis. In this prospective cohort study, we monitored the changes in resting and exercise pulmonary haemodynamics of scleroderma patients without initial PAH over a mean follow-up period of ∼4 years.All patients underwent exercise echocardiography and cardiopulmonary exercise testing at baseline and follow-up.
