[Taste disorders and associated factors in type 1 diabetes].
In order to study taste in type 1 diabetes (insulin-dependent), 57 consecutive diabetic patients (mean duration of diabetes +/- SEM = 11.4 +/- 0.4 years) and 38 control subjects underwent electrogustometry and chemical gustometry. The diabetic and control group were comparable with the exception of the ponderal index which was significantly higher in diabetics (p less than 0.05). A deterioration in taste appreciation was confirmed in the diabetic group compared to the control group on electrogustometry (mean threshold: 184.3 +/- 15.8 vs 58.7 +/- 9.2 mu A; p less than 0.001) and chemical gustometry (mean score: 13.2 +/- 0.7 vs 17.1 +/- 0.8; p less than 0.001). Electrical hypogueusia was found in 73% of the diabetics compared to 16% of controls (p less than 0.001). The 4 primary tastes were involved in the deterioration. Multivariate analysis associated the taste disorder with the diabetic status of the subjects, their alcohol and tobacco consumption. In the diabetic group the deterioration in taste was associated with the complications and duration of diabetes. On multivariate analysis peripheral neuropathy had the strongest association with taste disorders. These results suggest that deterioration in taste occurs during the progression of type 1 diabetes and that the taste disorder could be a degenerative complication of the disease. A neuropathic type mechanism could be involved.
