A previous hypothesis in which myasthenia gravis was explained by an immune response to acetylcholine receptors has been validated, and is here extended to cell receptors in general. Receptors on target cells, being accessible to circulating trophic hormones or transmitters, must also be accessible to antibodies which compete with the natural mediator for access to the site. To detect anti-receptor antibodies, physiological assay systems would be more sensitive than conventional immunological assays. Autoimmune responses to receptor sites would require a genetic predisposition to failure of immunological tolerance such as occurs in various autoimmune diseases. This hypothesis is supported by recent findings in hyperthyroidism and a type of insulin-resistant diabetes mellitus, and is applicable to other endocrinopathies, diseases in which dysfunction at receptor sites can be postulated, and regulatory functions within the immune system itself.

Major advances in knowledge of immunological diseases have resulted from observation of transient effects on children borne by women with such diseases. The discoveries that in Graves' disease and myasthenia gravis there are IgG antibodies directed against receptors sites are examples of such developments, while "ikiopathic" thrombocytopenic purpura is now accepted as immunological owing to its behaviour during pregnancy. In some instances observations of transient neonatal forms do not correspond with the disease manifestations in the mother. These discrepancies may be due to surgical removal of an organ vital to the disease process; inactivating damage by the disease to such an organ; presence of a blocking antibody of a molecular type not transferred across the placenta; differing tissue-antigen specificity or differing lymphocyte cooperation based on genetic variation. At present there are unexplained observations of fetal/neonatal effects in relation to diabetes mellitus and systemic lupus erythematosus which suggest that study of immunological parameters might be profitable. Determination of the HLA status of mother/fetus pairs may give rewarding clues. In the elucidation of the diseases now proven as antibody-mediated in the antibodies first discovered often turned out to be irrelevant red herrings.

For decases certain diseases, such as glomerulonephritis, polyarteritis nodosa, scleroderma and serum sickness, have been linked with autoimmune pathogenesis. During recent years a host of additional diseases traditionally thought to have some genetic predisposition but with obscure etiology have been suspected of being autoimmune in nature. Rheumatoid arthritis, diabetes, myasthenia gravis and thyroiditis are diseases of widely divergent organ systems, yet may well have common pathways of pathology via immune complexing mechanisms. Herein we present evidence supporting the concept that renal artery stenosis (occurring primarily in association with the middle aortic syndrome or after renal transplantation) is of immune etiology. Although the specific antigenic agent is still to be defined there is growing acceptance of the theory that medium and large vessels are subject to autoimmune vasculitis in many aspects similar to the autoimmune affections of small vessels. Several cases are presented. Some of these suggest an immune reaction by the natural history but without evidence of immunochemical reactants in the involved vessels, presumably because active disease was arrested at the time to study. In other cases immunofluorescent preparations demonstrate reactants in the walls of the vessels to document the hypothesis more convincingly.

Some decades ago, animal experiments have shown that inbred mice with completely identical genetic characteristics accept transplants between each other without any problem while transplants between individuals of genetically different strains are being rejected after a few days. It was also proven later that with men, genetical factors are responsible for acceptance or rejection of homologous transplants. These genetic factors, although they are called the HLA system, are located on the sixth chromosome. Methods were developed to determine the inherited HLA antigens with the help of antibodies present in the blood serum of pregnant women. The determination is of great importance in preparing transplants organ, especially of kidneys, because chances of successful transplantation are the greater, the better the correspondence of HLA antigens between donor and recipient. Furthermore, there exists growing indication that HLA antigens are coupled or even partly identical with the immune response gene products. These determine whether an individual is more or less suited to develop an immunity against bacterial or viral infections. Finally, there subsist associations of certain HLA antigens and diseases such as gluten enteropathy, myasthenia gravis, multiple sclerosis, diabetes mellitus and many others.

A 57-year-old woman with diabetes mellitus, hypothyroidism, idiopathic thrombocytopenic purpura, myasthenia gravis, systemic lupus erythematosus, atopy, and basal cell cancer of the skin developed a severe Coombs'-positive autoimmune hemolytic anemia which was resistant to treatment with large doses of azathioprine, cytoxan, and prednisone. One year after transcervical thymectomy the hemolytic anemia disappeared and the patient has maintained a normal hemoglobin and negative Coombs' test without immunosuppressants even since. We believe this case report to be the first recorded instance of thymectomy-induced remission of autoimmune hemolytic anemia in an adult.

The muscle, nerve terminal and end plates of 3 patients suffering from idiopathic Parkinson's disease have been studied electrophysiologically, histologically, histochemically and electron microscopically. No characteristic neuromuscular features of parkinsonism were discernible. Four additional patients suffering from idiopathic parkinsonism complicated by diabetes, myasthenia gravis and spinal atrophy were also studied.

A report on the neurological results of an investigation carried out on 38 patients with pigmentary degeneration of the retina. The ophthalmological investigation did not indicate a systemic disease. The neurological findings, however, revealed a systemic disorder in many cases.-The constitutions of 20 patients (52.5%) were marked by pathological stigmata. The EEG was abnormal in more than 50% of the cases. The EMG showed a prolonged nerve conduction time for 2 of a total of 4 deaf patients. The EMG also revealed a patient with both pigmentary degeneration of the retina and a mold form of myasthenia gravis. The biochemical results indicated hyperlipoproteinemia in 6 cases (15.8%), diabetes mellitus in 2 cases and a pathological increase of uric acid in the serum in 8 cases. These results suggest that pigmentary degeneration of the retina is not a homogenous disease. It must be seen as a "phenomenologically identical, polygenetic type of reaction" (Janzen). A comprehensive analysis of the individual case can therefore lead to implications which are of direct therapeutic significance.

Two new TCRV beta coding region polymorphisms were identified: V beta 6.9a/b and V beta 21.4a/b. In both cases, a single nucleotide difference gives rise to an amino acid exchange. Genomic typing by the PCR/sequence-specific oligonucleotide probing technique was performed to study a possible contribution of these two new polymorphisms in susceptibility to autoimmune diseases. However, there was no association with insulin-dependent diabetes mellitus, rheumatoid arthritis, juvenile rheumatoid arthritis, multiple sclerosis, myasthenia gravis or coeliac disease. On the other hand, significant differences were found between Caucasoid and Oriental populations in frequencies of the V beta 6.9 and V beta 21.4 alleles.
