[Anticardiolipin antibodies in connective tissue diseases].

The incidence of anticardiolipin (ACL) antibodies in connective tissue disorders other than systemic lupus was investigated in 113 subjects: 68 had rheumatoid arthritis, 23 primary Sjogren syndrome and 22 had systemic sclerosis. VDRL, thromboplastin time and determination of IgG and IgM ACL antibodies (ELISA) were performed in all subjects. Overall, 45% of patients were positive for ACL antibodies, mostly of the IgG variety (90%). No differences were observed among the investigated diseases. Positive ACL antibodies were not related to evidence of antiphospholipid syndrome nor to clinical characteristics of the different diseases. These results confirm that ACL antibodies may be present in connective tissue disorders other than systemic lupus, but they do not predict the development of antiphospholipid syndrome nor help to characterize the severity of the disease.

[Severe ischemia of the hand. Treatment with regional intravenous sympathicolysis with reserpine].

Treatment of severe hand ischemia a associated to progressive systemic sclerosis and other disorders is controversial. We studied prospectively 45 patients, 41 female and 4 males, over an 11 year period. Age ranged from 16 to 73 years, mean 46. Underlying disease was systemic sclerosis in 30, CREST in 8, overlapping syndrome in 4, systemic lupus in 1 and non rheumatic vasculitis in 2 patients. Treatment consisted of intravenous injection of reserpine, 1 mg, at a superficial arm vein after controlled local circulatory block for 15 min. Regional anesthesia was required in 38 patients. Adequate follow up was obtained in 32 females and 2 males, receiving a mean of 3.1 therapy sessions (range 1 to 13). Morphologic improvement from 3.09 +/- 0.16 to 1.57 +/- 0.13 and functional improvement from 3.6 +/- 0.12 to 1.75 +/- 0.14 (5 grade scoring system), was observed (p < 0.001). These results correlate with adequate rehabilitation confirmed clinically.

[Anticardiolipin antibodies in systemic lupus erythematosus: prevalence and clinical associations].

Anti-cardiolipin antibodies have been recently described in patients with systemic lupus erythematosus and other autoimmune disorders. Venous and arterial thrombosis, thrombocytopenia and recurrent abortion have been associated to the presence of these antibodies. Among 161 patients with systemic lupus we found 66% with anticardiolipin antibodies, mostly IgG type. Thrombosis and thrombocytopenia were more frequent in these patients (p < 0.05), especially among those with high titers. No association was found with central nervous system involvement, recurrent abortion, antinuclear or anti-DNA antibodies nor positivity for VDRL. These results support the frequent presence of anti-cardiolipin antibodies in patients with systemic lupus and their association to thrombosis and thrombocytopenia.

The long-term treatment of steroid osteoporosis with fluoride.

Twenty-two patients with steroid-induced osteoporosis were studied retrospectively to assess the effects on bone mass of fluoride therapy over 4 years. Thirteen of 19 patients with miscellaneous disorders and 2 with Cushing's syndrome received 1 g calcium/day, 50,000 IU vitamin D (D) weekly, and 40-60 mg/day sodium fluoride (F). Six patients with miscellaneous disorders and one with Cushing's syndrome received only Ca and vitamin D. The mean (+/- SD) cumulative dose of prednisone for fluoride-treated patients at the beginning of the study was 42 +/- 25 g, and for those patients treated with only Ca and vitamin D, 45 +/- 47 g, and during the study the cumulative dose was comparable in both groups. The bone mineral mass of the central skeleton was measured by neutron activation analysis and the results expressed as the calcium bone index (CaBI) which normalizes the results to that of young adults of the same body size (normal range 0.75-1.2). In the 13 patients with miscellaneous disorders treated with fluoride, the mean +/- SD CaBI rose from 0.65 +/- .03 to 0.75 +/- .03 after 3 years p less than 0.001) and to 0.81 +/- .11 at 4 years. Patients without fluoride had an initial mean CaBI of 0.70 +/- .08 and it was not significantly changed over 3 years, 0.68 +/- .09 and 4 years, 0.71 +/- .09. The rise in CaBI in fluoride-treated patients with steroid-induced osteoporosis including Cushing's syndrome was comparable to that of 61 patients with postmenopausal osteoporosis treated with fluoride.(ABSTRACT TRUNCATED AT 250 WORDS)

[Sacroiliac infection: clinical characteristics in 11 cases].

We report clinical and laboratory findings in 11 patients with septic sacro-iliitis. Fever, pain and immobility were prominent symptoms. Acute tenderness of the sacroiliac joint and elevation of the ESR were present in all. Joint puncture allowed identification of the infectious agent in 10 patients: S aureus 4, S typhi 3, E coli 2 and P mirabilis 1. Good clinical results were obtained after appropriate antibiotic therapy.

[Thyroid disease in progressive systemic sclerosis].

There is no agreement wither thyroid disease is a common feature of progressive systemic sclerosis (PSS). We evaluated 28 patients with proven PSS with determinations of T3, T4, TSH and Tg as well as antimicrosomal autoantibodies. Radioactive I uptake, thyroid scintigraphy, TRH test and fine needle biopsy were performed in selected patients. Twelve (43%) patients had clinical or laboratory evidence of thyroid dysfunction. Four patients had euthyroid goiter, 3 had evidence of autoimmune disease, 2 had chronic Hashimoto's thyroiditis, 1 was hypothyroid, 1 hyperthyroid and one has subacute thyroiditis. The CREST variant of PSS was most commonly associated with thyroid pathology. Our results indicated that thyroid disease is frequently associated to PSS. A complete clinical and laboratory evaluation is needed to confirm its presence.
