ECG changes in 49 patients with rheumatoid arthritis, 18 with ankylosing spondylitis, 47 with systemic lupus erythematosus, 17 with dermatomyositis, 21 with scleroderma and 7 with polyarteritis nodosa were compared with ECG changes in 106 control subjects. The classification of ECG findings was based mainly on the Minnesota Code. Compared with control subjects, pathological Q--QS, ST segment and T wave patterns were more common in all patient groups--including dermatomyositis, in which cardiac involvement has rarely been reported. P terminal force (PTF) was higher in the patient group. Conduction defects were probably more common in connective tissue diseases, whereas differences in ectopic beats, arrhythmias, QRS duration and QRS axis and R wave amplitude were not significant. The only significant difference between the steroid-treated patients and those without such treatment was the higher frequency of ST changes in the steroid-treated group. The results imply that heart affection is common in all connective tissue diseases. The several mechanisms underlying the cardiac involvement are reflected in many ways in the electrocardiograms of these patients, including an increased frequency of ECG changes mimicking those met in coronary heart disease.

Rheumatoid arthritis is a multisystem disease, with many clinical forms bearing close resemblance to systemic lupus erythematosus, dermatomyositis or polyarteritis nodosa. Although the involvement of the integument is not as disabiling as the joint disease, the extent of disability may be of sufficient magnitude to necessitate therapeutic intervention. Two patients are presented whose skin involvement was suggestive of cutaneous angiitis and who responded dramatically to treatment using sulfasalazine.

Antibody activity against mumps, measles, polio, and rubella viruses was determined in patients with juvenile rheumatoid arthritis (J.R.A.), rubella-vaccine associated arthritis, adult rheumatoid arthritis, other chronic systemic disorders (e.g., systemic lupus and dermatomyositis), and in a matched population of normal, non-rheumatoid (control) children. The antibody levels against mumps, measles, and poliovirus were similar in all patients. Rubella-antibody levels in rheumatoid arthritis and other systemic disorders were similar to those observed in controls. The mean rubella-antibody levels in rubella-vaccine arthritis were 4 times higher than in controls. The IgM and IgG rubella-antibody levels in J.R.A. were found to be 4-6 times higher when compared to titres observed in the controls. Highest antibody levels were seen in younger children with J.R.A. Detection of rubella-virus antigen was attempted by immunofluorescence in the sediment smears of synovial fluid of patients with J.R.A., adult rheumatoid arthritis, and other non-rheumatoid joint diseases. Specific staining for rubella virus antigen was observed in the synovial fluid of 33 percent of patients with J.R.A. No antigen was detected in the synovial fluid from other patients. These observations suggest a possible role of rubella-virus infection in J.R.A.

Samples of renal tissue from 373 patients were examined for the presence of immunoglobulin E (IgE) by immunofluorescent techniques. Only trace to ++ amounts ( on a scale of ++++) were found in 20 patients: 4/9 with post-streptococcal acute glomerulonephritis (GN), 5/30 with GN associated with systemic lupus erythematosus, 3/20 with membranous GN, 1/4 with Goodpasture's syndrome, 2/18 with recurrent microhematuria and focal GN, 1/5 with hemolytic anemia and uremia, 3/73 with renal homografts, and 1/5 with dermatomyositis. No IgE was found in 18 patients with lipoid nephrosis, 8 of whom were being treated with prednisone, nor in 5 patients with focal glomerular sclerosis and the nephrotic syndrome. Serum IgE was measured in 9 of the 20 patients with glomerular deposits of this globulin. With one exception, levels of IgE were within the range generally considered to be normal. However, they were greater than the mean of this range in all but two and near the highest limits of normal in most. Neither the amounts of serum IgE nor the degree of proteinuria could be related to the intensity of stain for IgE in the glomeruli of these patients.

Circulating immune complexes (CIC) were measured by three different methods in serum from 17 patients with systemic lupus erythematosus (SLE), 3 patients with "hydralazine-induced" SLE-like syndromes, 14 patients with discoid lupus (DLE), 8 patients with systemic sclerosis and 5 patients with dermatomyositis. Immune complexes were detected in 13 of the 17 patients with SLE. All patients with lupus nephritis and typical exanthema had circulating immune complexes. The concentration of immune complexes was inversely correlated to serum complements C4 and C3. All 3 patients with "hydralazine-induced" SLE-like syndromes had circulating immune complexes that disappeared after withdrawal of the drug. Immune complexes were detected in 3 of the 14 patients with DLE; all 3 patients with CIC had wide-spread DLE. In systemic sclerosis, CIC were detected in only 1 of the 8 patients. Four of the 5 patients with dermatomyositis demonstrated CIC in serum. No complement consumption was detected in dermatomyositis and the immune complexes may have been secondary to tissue destruction.

150 cases of chronic inflammatory lung diseases of unknown aetiology and assumed hyperergic (immuno-reactive) pathogenesis were examined for hypertensive pulmonary arterial lesions and for chronic cor pulmonale. Hypertensive lesions of the small pulmonary arteries were found in more than half of the cases with chronic disorders of long duration, but were inconspicuous in diseases of acute progressive character. Hypertensive lesions were found regularly in chronic interstitial pneumonia, frequently in scleroderma and rheumatoid arthritis and occasionally in dermatomyositis and disseminated lupus erythematosus. Chronic Cor pulmonale occurred in 16% of the cases with hypertensive arterial lesions of grade I (hypertrophy of media) and in 50% of grade II/III (hypertrophy of media and intimal fibrosis). Interstitial lung fibrosis plays an important role in the pathogenesis of cor pulmonale: two thirds of the cases with interstitial lung fibrosis had developed cor pulmonale and all the cases with cor pulmonale also had interstitial lung fibrosis. Hypertensive arterial lesions of grade IV-VI according to Heath and Edwards (angiitis, plexogenic and angiomatoid lesions) have been described in severe cases of pulmonary hypertension (congenital cardiac shunts, primary pulmonary hypertension). In secondary forms of pulmonary hypertension, as represented by our material, these changes are of little importance.

Since about 1950 especially, dermatologists world-wide have been utilizing the positive side-effects, discovered by chance, of all groups of antibiotic and antimicrobial drugs. These drugs are used to treat certain non-microbially induced dermatoses, without any knowledge of the mechanisms involved. A short history is given and the most important drugs and the indications for their use are described. The following drugs are undoubtedly effective and sometimes even the therapy of choice: tetracyclines in acne vulgaris and rosacea (including rosacea keratitis); penicillin G in acrodermatitis atrophicans and cold urticaria; dapsone in dermatitis herpetiformis and - as a powerful adjuvant - in acne vulgaris and rosacea. Before the discovery of the socalled immunodepressive drugs, tetracycline was the only alternative to - or at least a highly effective adjuvant of - cortisone in dermatomyositis and chloroquine in localised and systemic lupus erythematosus. Finally, clioquinole was life-saving in acrodermatitis continua in children until this condition was recently identified as a zinc-deficiency syndrome. Therapeutical mechanisms have been found only in the case of acne, rosacea and dermatitis herpetiformis. In most other diseases the nature of the therapeutical effectiveness of antibiotic and antimicrobial drugs still remains a mystery.

Serum immunoreactive prolyl hydroxylase protein and galactosylhydroxylysyl glucosyltransferase activity were measured in 54 patients wtih various dermatological diseases and compared with corresponding values in 32 control subjects. These serum enzymes were at the control level in the great majority of the patients, and no correlation was found between serum and skin enzymes, except for one weak correlation in lichen ruber planus. Some patients with psoriasis, lichen ruber planus, keloids, erythema nodosum or chronic discoid lupus erythematosus, however, did have at least one of these enzymes elevated in the serum, and a significant correlation (P less than 0.01) between the two enzymes was found in the total disease material. Thus it does seem that diseases limited only to the skin can sometimes raise these serum enzyme levels. The mean levels of serum immunoreactive prolyl hydroxylase and galactosylhydroxylysyl glucosyltransferase activity were significantly elevated (P less than 0.001) in active systemic connective tissue diseases such as systemic lupus erythematosus, scleroderma or dermatomyositis compared with the controls, and 4 out of 7 values for immunoreactive prolyl hydroxylase and 3 out of 7 for galactosylhydroxylysyl glucosyltransferase activity were above the 95% confidence limit of the controls. Since the levels of the skin enzymes were not elevated in most of these patients, however, the main sources for the elevated serum enzymes were probably tissues other than the skin.

Two cases are presented which have been treated anticonvulsively for many years - especially with Phenytoin and Mephenytoin. The clinical syndrom as well as the changes of the connective tissue show transitions of Progressive systemic sklerosis (PSS) to systemic Lupus Erythematodes (SLE) and Dermatomyositis. The correlation with the therapy is reflected in consideration of immunological phenomenons.

Sera from 378 patients were assayed for antibodies to extractable nuclear antigens (ENA), ribonucleoprotein (RNP) and nonnucleoprotein (Sm). Anti-ENA antibodies were not found in control subjects, patients with rheumatic diseases and negative fluorescent antinuclear antibodies (FANA), or in patients with rheumatoid arthritis, dermatomyositis, drug-induced lupus, idiopathic thrombocytopenic purpura (ITP), or hemolytic anemia with positive FANA. Anti-Sm antibodies were found in 32 per cent of patients with systemic lupus erythematosus (SLE) and were not found in any other condition. There were no significant clinical or serological differences between patients with and without anti-Sm antibodies. Anti-RNP antibodies occurred in 15 per cent of SLE patients, 9 per cent of scleroderma patients, and in 100 per cent of patients with mixed connective tissue disease. SLE patients with anti-RNP antibodies had a significantly lower anti-DNA antibody titer and a significantly lower incidence of nephritis and impaired renal function. Anti-Sm and anti-RNP titers did not vary with changes in clinical status. Awareness of the presence of anti-Sm and anti-RNP antibodies is diagnostically useful. Anti-RNP antibodies have a prognostic value as well.
