Abstract:
In the last few years there is a more frequent appearance of papers which suggest the viral etiology of juvenile diabetes mellitus, where the mumps virus is primarily pointed to as the etiological factor. Since there is a high incidence of diabetes in our Province as well as the presence of an epidemic appearance of mumps infections, we were of the opinion that there was good reason for us to study the influence of mumps infection on glucose tolerance. With our research we have proved that mumps leads to the disturbances of carbohydrate metabolism and this is the case not only in the acute stage of infection but also in the course of a two-year follow-up, and they develop as a consequence of the direct influence of the virus on the beta cells of the pancreas. Glucose tolerance disturbances were not in correlation with the changes on the exocrine part of the pancreas neither in the acute stage nor in reconvalescence. Hereditary factors also didn't influence the more frequent appearance of these disturbances in persons with a hereditary disease, which was confirmed statistically also (X2 = 0.67). By research we have proved that disturbances which take the course of the "slow virus infection" type also occur and that they are statistically more significant (X2 = 22.31) in relation to the glucose tolerance disturbances which develop due to a direct activity of the mumps virus.
Insights
Mumps virus infection can cause juvenile diabetes mellitus by directly affecting pancreatic beta cells. These glucose tolerance disturbances persist long-term and are not linked to hereditary factors or exocrine pancreas changes.
Area of Science:
- Virology
- Endocrinology
- Immunology
Context:
- Juvenile diabetes mellitus (type 1 diabetes) has a suspected viral etiology.
- Mumps virus is frequently implicated as a potential cause.
- High incidence of diabetes and mumps outbreaks in the region necessitated this study.
Purpose:
- To investigate the influence of mumps infection on glucose tolerance.
- To determine the direct impact of mumps virus on pancreatic beta cells.
- To explore the long-term effects of mumps on carbohydrate metabolism.
Summary:
- Mumps infection leads to carbohydrate metabolism disturbances, affecting glucose tolerance.
- These disturbances occur due to the direct influence of the mumps virus on pancreatic beta cells.
- Effects on glucose tolerance persist for at least two years post-infection, independent of hereditary factors or exocrine pancreas changes.
Impact:
- Provides evidence for mumps virus as an etiological factor in juvenile diabetes.
- Highlights the direct role of viral infection in pancreatic beta cell dysfunction.
- Suggests "slow virus infection" mechanisms may contribute to glucose intolerance.
