Appendicular bone mass was measured in a series of 50 patients with non-steroid treated rheumatoid arthritis, 20 with polyarticular seronegative psoriatic arthritis, and 30 with osteoarthrosis, and compared with that of 40 controls of similar age and sex. Distal forearm bone mineral content was reduced in patients with rheumatoid and psoriatic arthritis and increased in those with osteoarthrosi...

Medical records of 138 patients with psoriatic arthritis and 138 with rheumatoid arthritis were reviewed for the occurrence of an environmental factor triggering arthritis. Twelve (9%) of the patients with psoriatic arthritis had had an acute disorder immediately preceding onset of arthritis (an operation in four cases, articular trauma in three, abortion in two, myocardial infarction, thrombop...

While there are several commercially available treatment options for psoriasis and psoriatic arthritis, there remains a large number of individuals who are refractory to current modalities. In the recent past, there has been increasing evidence that interleukin (IL)-17 plays a vital role in the pathophysiology of psoriasis. Preclinical, phase II, and phase III studies of secukinumab (Cosentyx®)...

S pecific inhibition of the cytokine tumour necrosis factor a (TNFa) has yielded dramatic improvements in the symptoms, signs, and quality of life of patients with chronic inflammatory diseases of Th1 phenotype such as rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis, psoriasis, and Crohn’s disease. 23 The ability of antiTNFa therapy to inhibit disease progression in...

Despite having several modes of presentation, psoriatic arthritis usually can be readily distinguished from other forms of polyarthritis. Prominent features in all forms are a predilection for digital joints and occurrence of osteolysis and ankylosis. Rheumatoid factor is usually absent, and the prognosis appears to be better than that for rheumatoid arthritis. The relationship of HLA-B27 histo...

OBJECTIVE To describe the clinical management of psoriatic arthritis for patients being treated by dermatologists and rheumatologists in Spain. METHODS Multicenter, retrospective, naturalistic observational study in which demographic and clinical variables were recorded for patients diagnosed with psoriatic arthritis. Data referred to the previous 12 months and were collected during a single ...

OBJECTIVE To determine the natural history of hip joint disease in psoriatic arthritis (PsA) and identify clinical risk factors for its early identification. PATIENTS AND METHODS 504 patients with PsA according to ESSG criteria were studied. Mean follow up was 5.7 years (range <1-45). Mean age at onset of psoriasis was 32 years and of PsA, 39 years. The most common pattern of PsA at onset was...

According to the definition proposed by the International League of Associations for Rheumatology (ILAR), juvenile idiopathic arthritis (JIA) is defined as an arthritis of unknown etiology, starting under 16 years of age and lasting for at least 6 weeks, once other known conditions have been excluded. JIA represents the most common chronic rheumatic disease of childhood and is considered an imp...

A patient exhibiting typical features of classical rheumatoid arthritis and psoriatic spondylitis is described. The patient, a woman, presented at the age of 29 with an inflammatory arthritis. Twenty years later, she developed psoriasis, and after a further 3 years, she was first noted to have rheumatoid nodules and to be strongly seropositive. Now at the age of 60, she has a rigid spine with r...
