Objectives

Narrative objectives1

Osteonecrosis is assocated with high-dose corticosteroid therapy and systemic lupus erythematosus (SLE). Early-stage osteonecrosis has been frequently misdiagnosed due to a lack of symptoms and changes observed with simple x-ray imaging. Currently, MRI is the gold standard for initial diagnosis of osteonecrosis. The frequency of steroid-induced osteonecrosis as observed with MRI is highest in the knee, followed by the hip, ankle, and shoulder joints, in that order. Thus MRI of bilateral hip and knee joints are effective as the screening examination of osteonecrosis.
SLE is one of the most frequent diseases underlying steroid-induced osteonecrosis, and its diagnostic criteria and treatment guidelines has been well established. We reported a prospective MRI study of SLE patients with 44 % of incidence of osteonecrosis at about three months after the initial steroid therapy. To our knowledge, however, long-term natural history of asymptomatic osteonecrosis has been unknown so far.
The purpose of this study was to clarify the long-term natural history of asymptomatic and non-collapsed osteonecrosis associated with corticosteroid therapy in SLE patients using MRI.

Assessment

Primary outcomes

Changes of the necrotic area were evaluated as either improved, aggravated, or unchanged. Improvement was defined as either a reduction or disappearance of osteonecrosis, with reduction defined as an improvement of more than one type of the 2001 revised criteria for classification of osteonecrosis of the femoral head of the Japanese Ministry of Health, Labor and Welfare. Aggravation was defined as enlargement of a previous osteonecrotic lesion, a new lesion, and/or collapse of osteonecrosis. Enlargement included both cases that were enlarged after reduction of the necrotic area or were reduced after enlargement. Collapse was defined as MR finding of bone marrow edema with clinical symptom of pain. Collapse included cases subsequent to enlarged or new osteonecrotic lesions. Unchanged was defined as no change of the necrotic area.
A p-value less than 0.05 is considered significant using Fisher exact probability test.

Key secondary outcomes

The total cumulative corticosteroid dose (g), mean corticosteroid dosage (mg/day), and duration of corticosteroid treatment (years) were compared between joints with and without osteonecrosis.
