Several variants of generalised vitiligo can be recognised by their cutaneous distribution. In some, certain anatomical regions--e.g., hands--are predominantly affected while the cutaneous depigmentation in other variants shows a similar anatomical distribution to that of the internal structures affected in some of the autoimmune and rheumatic diseases. Five patients have been seen, and three described by others, with vitiligo affecting skin of eyelids and lower front of neck, reminiscent of the anatomical distribution of lesions in thyrotoxicosis with exophthalmos: two of these patients have thyrotoxicosis. Another variant of vitiligo mimicks the anatomical distribution of lesions in ankylosing spondylitis, Reiter's syndrome, and ulcerative colitis and there are cases simulating lupus erythematosus, rheumatoid arthritis, and psoriasis. It is suggested that the parts of the body affected in each vitiligo variant and its corresponding internal disease constitute a set os mosiac patches with distinctive shared characters. These may have morphogenetic functions during embryonic development and be potentially autoantigenic later in life.

The association between the presence or absence of two HLA antigens and coeliac disease, thyrotoxicosis and ankylosing spondylitis has been studied in patients and controls. The simple empirical logistic model and a refinement due to Dyke and Patterson have been used to examine which conditional associations are important.

Schizophrenia is of mysterious causation. It is not infectious, not congenital, but shows familial aggregation, the Mendelian genetics indicating involvement of multiple codominant genes with incomplete penetrance. This is the pattern for autoimmune diseases, such as Graves' disease of the thyroid, where forbidden clones of B lymphocytes develop, and cause thyrotoxicosis by secreting autoantibodies that react with the thyroid gland's receptor for thyroid-stimulating hormone from the pituitary gland. In 1982, Knight postulated that autoantibodies affecting the function of neurons in the limbic region of the brain are a possible cause of schizophrenia. Today, this is even more probable, with genes predisposing to schizophrenia having being found to be immune response genes, one in the MHC and two for antibody light chain V genes. Immune response genes govern the immune repertoire, dictating the genetic risk of autoimmune diseases. The simplest test for an autoimmune basis of schizophrenia would be trial of immunosuppression with prednisone in acute cases. The urgent research need is to find the microbial trigger, as done by Ebringer for rheumatoid arthritis and for ankylosing spondylitis. This could lead to prophylaxis of schizophrenia by vaccination against the triggering microbe.
