Sera were collected from 49 pairs of identical twins, 27 of whom were discordant (only one twin affected) and 22 concordant (both diabetic) for insulin-dependent diabetes. All were tested for antibodies to mumps, cytomegalovirus, rubella, Coxsackie virus types B1-5, and Mycoplasma pneumoniae. The diabetic co-twins had no more antibodies to any of the viruses than the non-diabetic co-twins of the discordant pairs. Antibodies to Coxsackie B2, rubella virus, and M pneumoniae were found more often in the discordant than in the concordant twins. In 30 of the 71 diabetic twins symptoms began when they were aged 4-6 years or 10-15 years. More concordant than discordant twins were diagnosed during the months January to March. Hence there was no direct evidence of a virus aetiology of juvenile onset diabetes in these twins, and the difference in antibody titres between the concordant and discordant twins was in keeping with a genetic difference between them. The age and time of onset suggested that environmental factors may be important in causing diabetes in the twins.

Antibodies titres against Coxsackie-B (CB) and mumps virus (MV) were determined in 180 normal subjects and two groups of diabetics, 236 with diabetes of recent onset (DRO) and 108 with diabetes of long duration (DLD). Positive antibody titres to these viruses were found more frequently in controls than in diabetics. In fact, the percentage of positive titres was significantly less than in controls in several instances particularly in juvenile onset diabetes of long duration. These data suggest that CB and MV are not causally related to human diabetes mellitus.

Pathologists have confirmed the specific nature of the insulitis lesion in diabetes requiring insulin. Data from genetic studies implicate both genetic and environmental influences as important in the appearance of overt disease. Certain HLA histocompatibility antigens are associated with insulin-dependent diabetes and have been interpreted as markers for closely linked immune response genes, a situation that may lead to beta cell susceptibility to viral injury or to uncontrolled beta cell autoaggression following beta cell damage. There is much circumstantial evidence that viruses may precipitate the disease (coxsackie) or may precede the disease onset by a long interval (mumps, rubella). However, susceptibility to virus, if it exists in human insulin-requiring diabetes, would appear on clinical grounds to be localized to the pancreas. Autoimmune phenomena are common in insulin-requiring diabetes, and there is both human and animal evidence that suggest that cell-mediated immunity may have a central pathogenic role. The recent explosion of new findings should lead to a clearer understanding of the nature of the disease, and this knowledge will hopefully lend itself to the prevention or arrest of the disease through immunological intervention, vaccination programs, or other means yet to be discovered.

Age, sex, and estimated time of onset of insulin-dependent diabetes were determined for children in Pittsburgh (N = 673), Gainesville (N = 976), Galveston (n = 741), and Melbourne (N = 851). The US cities had a decrease in new cases during the summer and peak incidence in January through April. In Melbourne, monthly trends were reversed: there were more cases during May through August. In US cities, but not in Melbourne, children less than 6 years old showed a greater variation by season than children 6 years old and older. Observations of the same fall and winter onset (in different calendar months) of insulin-dependent diabetes in Australia and the United States, and exaggeration of seasonal differences in young US children, suggest that onset of insulin-dependent diabetes is associated with seasonally varying viral diseases. Mumps and rubella infections do not seem to be responsible for much of the seasonal variation. Seasonal peaks of mumps and rubella are later than those observed for insulin-dependent diabetes, and immunization with live mumps and rubella viruses has not been associated with changes in incidence of insulin-dependent diabetes. An increase in disease incidence in boys over girls below age 6 years and in girls over boys at ages 6 through 11 years was consistently observed but not explained.

Data are collected here that may support the hypothesis that there is an infectious component in the genesis of insulin-dependent diabetes mellitus. The clinical and experimental data on which that hypothesis is based referring to viruses such as: mumps virus, rubella virus, encephalomyocarditis virus, and Coxsackie B viruses, are presented. The authors mention the pathogenic mechanism, which extends over the existence of diabetogenic genes linked to the major complex of the histocompatibility HLA system, as well as the existence of an autoimmune reaction induced by the infecting virus. This review shows up the large gaps that exist in the accurate knowledge we have about the possible infectious etiology of diabetes. However, it also offers different pathogenic possibilities for further experimental investigations on bases that are reasonably scientifically consistent.

Serum immunoreactive trypsin (SIT) concentrations were measured in 244 patients with infectious illnesses and in 281 children with diabetes of recent onset. Results were compared with reference ranges established in 107 patients with non-infectious, non-diabetic illnesses, in whom SIT concentrations were found to increase with advancing age. Reduced or undetectable concentrations of SIT were associated with diabetes in children and with a few cases of severe childhood infection. Increased SIT concentrations were associated with virologically confirmed cases of infection with mumps and Coxsackie B virus infection, and with clinical diagnoses of mumps, PUO, and meningitis in children, and with Bornholm disease, cardiac infection, and respiratory infection in adults. It is suggested that silent invasion of the exocrine pancreas with elevation of the SIT concentration may accompany infection by Coxsackie B, mumps, and, possibly, other viruses.

Sixteen cases of parotitis and 2 cases of diabetes mellitus after mumps vaccination have been reported since the introduction of the live attenuated mumps vaccine in the F. R. Germany in the fall of 1976. Due to the post-vaccination incubation of 7 to 10 days, support is given to the assumption that these cases are vaccine induced and not coincidental wild virus infections. The diabetes mellitus cases, however, are too few to be included in this rational.

Examination of a patient consulting for infertility consists of 3 steps: clinical and medical history, spermogram and auxiliary instrumental or laboratory tests. The clinical exam includes thorough questioning on drug and toxic exposure, infections particularly mumps, trauma, and surgery; and physical examinations for descended testes, varicocele, and congenital defects. The spermogram, done on a specimen 3-5 days after the last ejaculation, includes volume, pH, sperm count, fructose content, and a check for inflammation or infection. Serum testosterone, luteinizing hormone and follicle stimulating hormone are determined, and it is well to test for diabetes, hypothyroidism, and antisperm antibodies in the partner's cervical mucus. Instrumental tests include urography, uretrography, X-ray of the seminal tract, and testicular biopsy. The effective treatments are surgery for varicocele or an obstacle in the excretory ducts, or treatment with androgens, gonadotropins, vitamins, arginine, corticoids, or thyroid hormones. Artificial insemination is sometimes helpful in oligospermia or a malformation such as hypospadia where the semen is normal but ejaculation is abnormal. Often the mere act of treatment overcomes psychological anxiety, and increases the couple's changes of pregnancy.

In the Tri-State Leukemia Survey, the history of diseases in 605 adult male leukemia cases 15 years and older and in 668 adult male population controls was examined. These diseases occurred at least 1 year before leukemia was diagnosed. The data were based on respondents' answers that the disease was diagnosed by a physician; the respondent was either the subject or his spouse. Of 30 diseases studied, 7 showed an excess among the patients with leukemia: infectious hepatitis, eczema, psoriasis, diabetes, arthritis and rheumatism, heart disease, and ankylosing spondylitis. Mumps had a lower reported occurrence among the cases, whereas pneumonia was less frequent in acute lymphatic cases than in population controls. Three diseases occurred significantly less in controls than in persons with specific histologic types of leukemia. Our data revealed a more frequent history of herpes zoster (shingles) in chronic lymphatic leukemia, more hives in acute chronic myeloid cases, and meningitis in acute myeloid leukemia. When we only considered the patients' responses, more of them admitted having had acne than did our controls. The remaining diseases--childhood viral diseases, infectious mononucleosis, smallpox, typhoid fever, dysentery, scarlet fever, tuberculosis, asthma, hay fever, and goiter did not occur more frequently in cases than in controls. The findings were consistent with evidence from previous laboratory and clinical studies. The increased occurrence of infectious hepatitis in our case series is consistent with the findings of other studies showing an increased frequency of Australia antigen in patients with hepatitis, leukemia, and Down's syndrome.

Viral infection has been suggested to play a triggering role in the pancreatic beta cell destruction which occurs in insulin-dependent diabetes (IDDM). However, the underlying mechanism of this phenomenon is unknown. In this study a human insulinoma cell line has been infected with measles, mumps and rubella viruses since a temporal association is reported between the clinical onset of IDDM and diseases caused by these viruses. The infection with measles and mumps viruses induced the release of interleukin-1 (IL-1) and interleukin-6 (IL-6) by the cell line as assessed by a bioassay and up-regulated the expression of human leucocyte antigen (HLA) class I and class II antigens as evaluated by cytofluorimetric analysis. Stimulation with rubella virus induced the release of IL-6 only and had no effect on HLA antigen expression. These data show for the first time that IL-1 and IL-6 secretion by an insulinoma cell line may occur after viral infection and suggest that cytokine release and increased expression of HLA molecules by beta cells may act to induce the immune response towards beta cells in IDDM.
