[Stress hormones liberated by fangotherapy. ACTH and beta-endorphin levels under heat stress].

In 6 healthy subjects submitted to fango therapy in the Euganean thermal baths (Italy), the plasma concentrations of beta-endorphin and ACTH increased transitorily but significantly. These results correlate with the release of these peptides by the pituitary in response to thermal stressing. The analgesic and hypothermic action responsible for good toleration of thermal stress induced by fango therapy, can be explained by this increase in plasma beta-endorphin. The repeated brief increases in plasma beta-endorphin during thermal treatment result in progressive improvement in articular and muscular symptomatology. The results of our study on plasma levels of ACTH confirm that the thermal stress associated with fango therapy activates the pituitary gland. Immunomodulatory effects are discussed.

Anti-double-stranded DNA antibodies in the healthy elderly: prevalence and characteristics.

Using Crithidia luciliae fluorescent assay a significant prevalence (7.6%; P less than 0.006) of anti-double-stranded DNA antibodies was found in a healthy old population. A negative enzyme-linked immunosorbent assay for anti-total histone antibodies excluded a false-positive reaction. Anti-double-stranded DNA antibodies in the aged differed from those found in patients with systemic lupus erythematosus and were characterized by a low titer (95.6% of cases), belonging to the IgA class alone (95.6%), no complement-fixing ability (100%), and negativity to Farr assay (100%). It is concluded that, in elderly subjects without signs and symptoms of disease, including systemic lupus erythematosus, such a peculiar anti-double-stranded DNA antibody may be detected.

Autoantibodies of systemic rheumatic diseases in the healthy elderly.

Antinuclear antibodies, anticardiolipin antibodies and IgM rheumatoid factor were determined in 300 healthy aged subjects, comparing their prevalence to that in 100 healthy subjects aged between 19 and 44 years and 352 patients under 65 years of age, affected by various systemic rheumatic diseases. Increased production of IgM rheumatoid factor and antinuclear and anticardiolipin antibodies was found as characteristic of aged humans, and suggested that a correction for age should be considered in evaluating the clinical significance of autoantibody profiles in elderly patients.

[Electrocardiographic disorders in diverse clinical variations of scleroderma].

The electrocardiograms of 130 patients affected by scleroderma, 117 with systemic sclerosis (67 with diffuse and 50 with limited form) and 13 with localized scleroderma were analyzed. ECG was normal in 44.6% of cases, respectively in 39.3% with systemic sclerosis and in 92.3% with localized scleroderma. The more frequent electrocardiographic abnormalities were supraventricular and ventricular premature beats, right bundle branch block, left anterior hemiblock, low QRS voltages, ST-T wave abnormalities and Q or QS aspects. All the abnormalities above resulted to be more frequent in the patients with diffuse systemic sclerosis in comparison to the patients with limited systemic sclerosis. Our results confirm that the cardiac involvement appears to be much more serious in the diffuse systemic sclerosis.

Hyper-IGD syndrome: a new case treated with colchicine.

We report a new case of hyper-IgD syndrome, a recently described disease characterized by recurrent episodes of fever with headache, bilateral cervical lymphadenopathy and, more rarely, abdominal pain and diarrhoea. Polyclonal increase of serum IgD is the most important laboratory finding. Etiopathogenesis and differences with familial Mediterranean fever are discussed. Moreover, good results obtained with colchicine treatment are also reported.

[Fibroblastic rheumatism. A clinical and histological entity].

In 1980 was described for the first time a disease which seemed unknown until then. From that time three cases have been published. The current study summarizes their common characteristic, combining joint involvements to nodular-type involvements to systemic involvement, i.e. a specific histology. This entity has been named fibroblastic rheumatism. Nosologically, it is situated between juvenile fibroblastoses without joint involvement and with nodules, and adult sclerodermis with joint and systemic involvement without nodules.

Phospholipids in inflammatory synovial effusions.

The concentration of phospholipids and proteins was determined in 23 inflammatory synovial fluids obtained from human knee joints. The synovial fluid to plasma phospholipid ratio (0.48 and 0.37 at high and low inflammatory state) was lower than the value found for the total protein content (0.68 and 0.53, respectively) indicating that phospholipids were more discriminated than proteins in their transfer from plasma to the synovial space. Constant amounts of phosphatidylinositol were found in all synovial fluids, whereas trace amounts of lysophosphatidylethanolamine and phosphatidylserine were more frequent in the active inflammatory state. A decrease in the relative amounts of phosphatidylcholine and phosphatidylinositol with respect to plasma suggested the possibility of phospholipid hydrolysis in the synovial compartment. In agreement, determinations of phospholipase activity disclosed the presence of a phospholipase A2 in the fluid phase of synovial effusions. Phospholipid derivatives formed in the synovial space may thus contribute to the amplification of the inflammatory response.

Anticentromere antibody in localized scleroderma.

Using metaphase chromosome spreads as substrate for indirect immunofluorescence technic, we observed anticentromere antibody in three of twenty-five patients affected with various clinical forms of localized scleroderma. Anticentromere antibody is generally considered a serologic marker of the CREST syndrome, a more benign subset of systemic sclerosis. However, none of the three anticentromere antibody-positive patients with localized scleroderma had Raynaud's phenomenon, acrosclerosis, or any signs or symptoms of systemic disease; on physical and laboratory examination, they showed only typical cutaneous features of localized scleroderma: two showed linear scleroderma, and one showed localized morphea. A 2-year 8-month follow-up of two patients did not disclose any clinical evidence of systemic sclerosis. The occurrence of anticentromere antibody in patients with localized scleroderma seems to offer supportive evidence that a relationship exists between localized scleroderma and systemic sclerosis.

Knee arthrography: effects of various contrast media and epinephrine on synovial fluid.

Changes in synovial fluid leukocytes, total protein, and total complement were studied in 58 patients after they underwent single contrast material-enhanced knee arthrography with ionic (sodium iothalamate, sodium meglumine diatrizoate, meglumine iothalamate) and nonionic (iopamidol, iohexol) contrast media. In 30 of 58 cases, 0.3 mg epinephrine was also injected. In patients examined without epinephrine, a significant increase in the number of leukocytes was observed when sodium iothalamate and sodium meglumine diatrizoate were used. When administered with epinephrine all ionic compounds produced significant leukocytosis; articular reactions were most evident in patients examined with sodium salts. No inflammatory changes in the synovial fluid were observed when nonionic compounds were used. These data suggest that sodium-containing compounds produce a greater reaction in the joint compared with other contrast media, nonionic compounds are better tolerated by the joint, and epinephrine increases the articular reaction to ionic contrast media.

Nuclear membrane-staining antinuclear antibody in patients with primary biliary cirrhosis.

An antinuclear antibody specific for nuclear membrane (ANMA) was observed by the immunofluorescence method in sera from patients with primary biliary cirrhosis (PBC). ANMA was present in 18 of 63 PBC sera (28.5) and in 1 of 431 control sera (0.2%). Its reaction appeared as a thin fluorescent ring confined to the nuclear envelope and was more evident when the sera were highly diluted and the fluorescence, due to frequently associated antimitochondrial antibody, faded. The ANMA fluorescent pattern was confirmed by indirect immunoperoxidase staining. ANMA was seen on both tissue cryostat sections and HEp-2 cells. It was a poorly or non-complement-fixing IgG, specific for an antigen resistant to DNase I, RNase, and trypsin. The significance of its presence in PBC in unknown at present. Identification of its antigen with one of the centromeric antigens is suggested.

Association of anti-centromere and anti-Scl 70 antibodies in scleroderma. Report of two cases.

In testing for antinuclear antibodies the sera of 121 patients affected with scleroderma, we found in 2 of them the concurrent presence of anti-centromere and anti-Scl 70 antibodies. Since the association of these antibodies has never been reported, to the best of our knowledge, we report the clinical and serological features of the 2 patients. Both subjects were women with an incomplete CREST syndrome (RST), a relatively limited involvement of the skin, a mild pulmonary fibrosis without apparent signs of other visceral involvement. On the other hand, the clinical course of the disease was different in the 2 cases. One patient had a longer disease duration and up to date the clinical features appear to be unchanged; the other had a shorter disease duration, when suddenly she died of cardiac arrest.

Prevalence of anticentromere antibody in blood relatives of anticentromere positive patients.

Anticentromere antibody (ACA) was investigated in 116 blood relatives of 22 ACA positive patients affected with scleroderma and, for comparison, in 82 healthy subjects matched for age and sex who belonged to 25 families. No relative showed any evident scleroderma symptom although in 8 an unusual cold sensitivity of the extremities was present. ACA at a low titer (40), was found in 4 relatives (3.44%), while it was absent in control sera. The 4 ACA positive relatives were first as well as second degree relatives of probands. Two had familial disease: one idiopathic chronic hypoparathyroidism and the other mental retardation. The third had myasthenia gravis and the fourth unusual cold sensitivity and allergic dermatitis. At present we cannot explain the significance of ACA occurrence in relatives of ACA positive patients. Followup clinical and serological studies could show a possible association of low titer of ACA with subclinical scleroderma features in patients who later develop overt disease.

Double-blind multicentre study of the activity of S-adenosylmethionine in hip and knee osteoarthritis.

A randomized double-blind multicentre clinical trial was carried out to verify the effectiveness and tolerance of S-adenosylmethionine (SAMe) versus ibuprofen in 150 patients with hip and/or knee osteoarthritis. Both drugs were given orally 400 mg thrice daily for 30 days. SAMe exhibited a slightly more marked activity than the reference drug in the management of the various painful manifestations of the joint disease. Minor side-effects developed in five patients of SAMe group, and in 16 patients of ibuprofen group. No drop-outs occurred. No changes were observed in the routine laboratory tests.
