OBJECTIVE Assess ustekinumab efficacy (week 24/week 52) and safety (week 16/week 24/week 60) in patients with active psoriatic arthritis (PsA) despite treatment with conventional and/or biological anti-tumour necrosis factor (TNF) agents. METHODS In this phase 3, multicentre, placebo-controlled trial, 312 adults with active PsA were randomised (stratified(More)
Acetaldehyde-dependent chemiluminescence has been found to be a sensitive technique for the study of superoxide and hydrogen peroxide formation in beef heart mitochondria. The system responds to ATP and antimycin A with increased emission intensities and to ADP and rotenone with decreased intensities, indicating that the chemiluminescence reflects the(More)
Neonatal lupus Erythematosus (NLE) is a disorder characterized by maternal autoantibodies against RNA protein complex, Ro/SSA or SSB/La. These maternal IgG antibodies cross the placenta and potentially lead to fetal tissue damage and the clinical manifestations NLE. NLE is uncommon, affects females more than males, has no race predilection, and involves(More)
OBJECTIVE To assess the efficacy and tolerability of etanercept to treat psoriatic arthritis. MATERIALS AND METHODS A total of 1,122 patients who had active psoriatic arthritis were enrolled in a Phase 4, non-randomized, open-label, single-arm, 24-week study. These patients had clinically stable, plaque psoriasis involving >or=10% body surface area and(More)
Morphea (localized scleroderma), and lichen sclerosus et atrophicus (LSA) share common features with acrodermatitis chronica atrophicans (ACA), a known chronic form of borreliosis. These include similar histologic findings such as diffuse dermal fibrosis. These observations have led several investigators to consider the possibility of Borrelia burgdorferi(More)
Two patients with a hypersensitivity vasculitis in association with propylthiouracil (PTU) administration are described. Although both patients presented with a cutaneous eruption, our first patient suffered severe systemic manifestations and the second patient's involvement was primarily limited to the skin. Patients with a vascular hypersensitivity(More)
Systemic sclerosis is uncommonly associated with hematologic malignancies. We report the case of a patient who had chronic myelogenous leukemia 3 years after the CREST variant of systemic sclerosis was diagnosed. She also later had porphyria cutanea tarda. The majority of patients who had hematologic malignancies after the diagnosis of systemic sclerosis(More)
