Do estrogens improve bone mass in osteoporotic women over ten years of menopause.

A retrospective analysis of 24 patients with established osteoporosis and with ten or more years of menopause treated with conjugated estrogen, progesterone and calcium followed for one year has been performed. Treated women received 0.625 mg/day of conjugated estrogen from day 1 to 25, 5 mg/day of medroxiprogesterone from day 13 to 25, of each cycle, plus calcium (500-1000 mg/day), during one year (12 cycles). As control group was used 18 age-matched that received only calcium (500 a 1000 mg/day). All patients had at least two dual-photon spine and proximal femur (neck, Ward's triangle and trocanter) densities measurements performed 12 months apart. Estrogen treatment was associated with increased bone mineral density at spine and trocanter. Control group did not present any statistically change after one year in any site studied. We concluded that women with ten or more years of menopause and established osteoporosis treated with replacement hormonal therapy and calcium results in improvement of bone mineral density. These data support that women with ten or more years of menopause respond to estrogen replacement therapy with absolute increments in bone density similar to those seen in younger women, in the early menopause.

[Rheumatic manifestations of acquired immunodeficiency syndrome (AIDS)].

120 AIDS patients (mean age 33 +/- 9 years, 108 males) were evaluated regarding rheumatic manifestations. According to CDC's classification, 18.3% belonged to group II, 28.3% to group III, and 53.4% to group IV. Arthralgia was present in 33 patients (27.5%), and in only 8 could be associated with infections other than HIV (5 cases of tuberculosis, 3 P. carinii, and 1 gonococcal infection). Incidence of arthralgia was equal in either sex. Arthritis was present in 8 patients, 2 of them with Reiter's syndrome. In 6 patients arthralgia was the first symptom (3 with arthritis) before AIDS diagnosis. There was a higher incidence of dry mouth, dry eyes, and muscular complaints in patients with arthralgia than in patients without arthralgia. Antinuclear antibodies and rheumatoid factor were absent in the serum of the patients studied. Arthritic manifestations possibly occur in AIDS, even in patients without other clinical manifestations, as a reactive state to HIV infection.

A study of synovial membrane of patients with systemic lupus erythematosus (SLE).

In this study, 30 percutaneous synovial knee biopsies were taken from patients with systemic lupus erythematosus (SLE) that had been diagnosed in accordance with ARA criteria. Acute articular involvement was present in 16 cases. The synovial membrane was then examined using routine histological techniques and by direct immunofluorescent methods. The most frequently observed histological picture was comprised of: a) synoviocyte hyperplasia, b) scarce inflammatory infiltrate, c) vascular proliferation, d) oedema and congestion, e) fibrinoid necrosis and intimal fibrous hyperplasia of blood vessels, g) presence of fibrin on the synovial surface and fibrin-like deposits in the chorion. It is concluded that immunofluorescence can be used in the characterization of typical cases but is not specific.

Systemic lupus erythematosus: a family study of 25 probands.

We studied 120 first-degree relatives (FDRs) of 25 systemic lupus erythematosus (SLE) probands and 59 non-genetically associated individuals who were in close contact with the SLE patients. A significantly greater frequency of antinuclear antibody (ANA) positivity was found among the FDRs than in the control group (p less than 0.01). No significant difference was found in ANA positive between the female and male FDRs. Articular complaints or Raynaud's phenomenon were observed in 15% of the FDRs and in only 2% of the controls (p less than 0.05). Female FDRs had a greater number of rheumatic complaints than male FDRs (p less than 0.05) and a significant association was found between rheumatic complaints and ANA positivity (p less than 0.001) among the total FDRs.
