Comparative Study Clinical TrialComparison of the effect of alendronate on lumbar bone mineral density and bone turnover in men and postmenopausal women with osteoporosis.
The purpose of the present study was to compare the effect of alendronate treatment on lumbar bone mineral density (BMD) and bone turnover in men and postmenopausal women with osteoporosis. Sixty men with primary or secondary osteoporosis and 318 women with postmenopausal osteoporosis were treated with alendronate. The primary end points were lumbar BMD and urinary cross-linked N-terminal telopeptides of type I collagen (NTX) and serum alkaline phosphatase (ALP) levels. ⋯ Reduction in urinary NTX level and increase in lumbar BMD were smaller in men than in postmenopausal women. The incidence of vertebral and nonvertebral fractures was 10.6 and 8.5%, respectively, in men and 8.3 and 7.5%, respectively, in postmenopausal women, with no significant difference in these incidences between them. These results suggested that alendronate treatment effectively increased lumbar BMD from baseline in men with primary or secondary osteoporosis following reduction in bone turnover, although its efficacy did not appear to be greater than in postmenopausal women with osteoporosis.

Dietary calcium and bone mineral density in premenopausal women with systemic lupus erythematosus.
The primary objective of this study was to determine the relationship between dietary calcium intake and bone mineral density (BMD) in premenopausal women with systemic lupus erythematosus (SLE) on corticosteroids (CS). The secondary aim was to identify other risk factors for osteoporosis in these patients. A cross-sectional sample of patients attending the SLE Clinic at a teaching hospital was recruited. ⋯ Duration of SLE significantly correlated with cumulative CS dosage. In conclusion, 6.7% of these Asian premenopausal SLE women had osteoporosis and only 46.7% had normal BMD. Daily dietary calcium intake did not correlate with BMD.

Case ReportsPeripheral neuropathy in two patients with rheumatoid arthritis receiving infliximab treatment.
Antitumor necrosis alpha agents have been successfully used for the treatment of rheumatoid and seronegative arthritis, Crohn's disease, psoriasis, and severe cases of vasculitis. Several side effects have been observed in patients receiving these agents including hypersensitivity reactions, infections, drug-induced lupus, or demyelinating syndromes. The presence of peripheral neuropathy has been reported only in isolated cases. We describe two cases of peripheral neuropathy which occurred in patients with rheumatoid arthritis receiving infliximab treatment, one with multifocal motor neuropathy with conduction block and another with axonal sensory polyneuropathy, reversed upon discontinuation of infliximab and intravenous gammaglobulin treatment.

Case ReportsInterstitial lung disease in a patient with antisynthetase syndrome and no myositis.
Interstitial lung disease in patients with antisynthetase syndrome and no evidence of myositis is rare and may precede other disease manifestations. We report a patient who initially presented with symptoms primarily related to lung involvement. ⋯ Antisynthetase syndrome should be considered in patients presenting with interstitial lung disease with no evidence of myositis. Appropriate laboratory testing with measurement of specific autoantibodies may help in the early diagnosis and treatment of the syndrome.

Comparative StudyThe frequency of thyroid antibodies in fibromyalgia patients and their relationship with symptoms.
We determined the frequency of thyroid autoantibodies in fibromyalgia (FM) patients and the relationship between FM symptoms and these antibodies. Euthyroid 128 FM patients, 64 rheumatoid arthritis (RA) patients, and 64 healthy control subjects were included in the study. The sociodemographic features and the clinical features of FM patients were determined. ⋯ FM patients had thyroid autoimmunity similar to the frequency in RA and higher than controls. Age and postmenopausal status seemed to be associated with thyroid autoimmunity in FM patients. The presence of thyroid autoimmunity had no relationship with the depression scores of FM patients.
