Measurements of transcobalamin II (T.C. II) concentrations in 26 patients with lupus erythematosus, 4 with dermatomyositis, 2 with autoimmune haemolytic anaemia, and in 40 immunosuppressed renal-transplant patients showed that T.C. II levels were raised during active phases of autoimmune disease. Changes in T.C. II levels correlated better with the clinical course of autoimmune disease than did changes in C3, the titre of antinuclear antibody, or native D.N.A.-binding capacity.

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.

A case of dermatomyositis is reported in a 50-year-old woman receiving D-Penicillamine therapy for rheumatoid arthritis. There was no evidence of neoplasia on full investigation. Remission of dermatomyositis occurred on withdrawal of D-Penicillamine.

Hemopexin, a serum glycoprotein that binds free heme and transports it to hepatic parenchymal cells, has been measured by radial immunodiffusion. We have confirmed elevation of serum hemopexin concentration in Duchenne's muscular dystrophy patients and carries, and demonstrated elevations in dermatomyositis/polymyositis and myasthenia gravis, but not in amyotrophic lateral sclerosis. In monkeys, elevations of hemopexin levels were specifically induced by hematin injections, muscle-crush, or myoglobin injections. Myoglobin leakage is the likely explanation of hemopexin level elevation in Duchenne's dystrophy patients and carriers and in dermatomyositis/polymyositis. In myasthenia gravis there might be a slight myoglobin leakage not heretofore suspected; or, the elevation of hemopexin levels might be a new reflection of a dysimmune state in myasthenia gravis, and perhaps as such is a further incrementing factor in dermatomyositis/polymyositis. Hemopexin, presumably as a longer-phase reactant, is sometimes an index of neuromuscular disease when other data are negative or equivocal.

Four children aged 31/2 to 13 years, who developed allergic alveolitis as a result of antigenic exposure in a domestic situation are described. The clinical symptoms consisted of gradual onset of increasing dyspnoea, chronic cough and weight loss. Lung function tests showed characteristic reduction in vital and diffusion capacity. Serologically, antibodies against animal antigens were demonstrated in all patients. Radiologically there were pronounced reticular changes in both lungs affecting mostly the middle and lower zones. Occasionally there were miliary and sometimes confluent shadows. In differential diagnosis, virus infections, pneumocystis carinii, fungus infections, dermatomyositis, sarcoidosis and tuberculosis had to be considered. Apart from a short course of steroid treatment, it is necessary to make certain that the children are no longer exposed to the causal antigen. Under these conditions the prognosis is good, but otherwise the disease, as in adults who are continuously exposed to the antigen, results in pulmonary fibrosis.

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.

A whole-body scan with 99mTc-pyrophosphate and 85Sr-nitrate demonstrates extension of calcinosis in one case of dermatomyositis with cutaneous, subcutaneous, and muscular calcinosis. The authors suggest the potential use of 99mTc-phosphate compounds as an auxiliary instrument in the evaluation of dermatomyositis-polymyositis syndrome.

Intraendothelial tubular aggregates were found in small dermal blood vessels in three healing superficial wounds in patients receiving systemic corticosteroids. Similar inclusions were also demonstrated in two wounds in healthy subjects, but were not found in normal (unwounded) skin of either healthy subjects or steroid-treated patients. Tubular aggregates of similar structure have previously been described as occurring in 'connective tissue' or 'auto-immune' diseases, including lupus erythematosus and dermatomyositis, both in the skin and in internal organs. Although it has been suggested that such aggregates are of viral origin, their morphogenesis and significance remain undertermined. Our findings do not support a viral cause, but suggest that these structures are probably a product of regenerating endothelium.

The authors describe two patients suffering from cancer accompanied with paraneoplastic skin disorders (bullous pemphigoid, dermatomyositis). Before the diagnosis of stomach cancer was obtained by X-ray examination, the IgM-level was found lower than in normal persons. The value of the IgM-estimation in the serum seems to be high in the diagnosis of tumours. Other causes of the decreased IgM-level than tumours and paraneoplastic disorders of the skin were not found.
