[Gustatory disturbances as sideeffect of medical treatment (author's transl)].

A review of the pharmacological induced taste disorders is given. Many patients complain only of a spontaneous metallic, bitter or salty sensation in their mouths. More serious is the development of a dissociated hypogeusia or even an ageusia. 7 cases with gustatory disturbances caused by orally given medicine are presented. The phenylbutazone, oxyphedrine, carbamazepine, Muskel-Trancopal comp. (Chlormezanon, Paracetamol) and Lioresal (baclofen) were accused to have caused a partial or complete loss of taste. After the treatment had been discontinued it took weeks or even months for a complete recovery.

Anorexia nervosa responding to zinc supplementation: a case report.

An emaciated 16-year-old female with anorexia nervosa was hospitalized for treatment of vomiting, epigastralgia and diarrhea. The finding of a taste disorder, low serum alkaline phosphatase activity and relatively low serum zinc level strongly suggested a zinc deficiency. Zinc was initially administered intravenously (40 mumol/day) for 7 days, then orally (15 mg elemental zinc/day) for about 60 days. Her digestive symptoms disappeared after the second day of intravenous treatment and she began to gain weight. She rapidly regained her normal weight after one month of receiving the oral zinc supplementation. Both exocrine pancreatic function and intestinal absorption were improved by the prolonged oral administration of zinc. In such cases zinc supplementation may be a therapeutic option in addition to psychologic and other approaches to management.

Early detection of diabetic patients at risk of developing degenerative complications using electric gustometry: a five-year follow-up study.

OBJECTIVES: Taste impairment has been reported during the course of diabetes. Although a degenerative mechanism has been suspected, the natural history of taste disorders in diabetes remains unknown. The purpose of this study was to describe the five-year evolution of electric gustometry in diabetic patients compared to healthy control subjects and with reference to degenerative complications of the disease. METHODS: Electrogustometry was studied initially and after 5 years in 73 diabetic out patients and 25 control subjects. None of them had any known cause of taste impairment other than diabetes. Diabetic patients and control subjects did not differ for demographic data and confounding factors. RESULTS: After five years, the electrogustometric threshold (EGT) significantly increased (51 +/- 6 vs 95 +/- 11 microA; p < 0.001), whereas slight changes occurred in control subjects (23 +/- 4 vs 25 +/- 5 microA; NS). Frequency of electric hypogeusia (EGT > or = 100 microA) increased from 11 to 46% in diabetic patients (p < 0.001), but did not vary in control subjects (4%). EGT was not strongly associated with individual factors such as blood pressure, tobacco and alcohol consumption, but correlated with age (p < 0.001). In the diabetic group, higher EGT were observed in patients treated with insulin (p < 0.001). EGT and its changes were associated with degenerative complication (p < 0.001), but neither with metabolic control, nor with duration of diabetes. Using multivariate analyses, the strongest associations were found with peripheral neuropathy and microalbuminuria (28 to 45% of variance explained; p < 0.001). The predictive value of initial hypogeusia on neuropathy at follow-up was 88% for a positive test and 63% for a negative one. CONCLUSIONS: These results suggest that the taste nerves transduction function is impaired during the course of diabetes. This impairment is associated with an increased occurrence of degenerative complications, leading to suspect a similar pathophysiological mechanism. Electric gustometry could be an interesting test for early screening for diabetes complications.

Abnormalities of taste sensation in cancer patients.

In fifty patients with cancer, subjective and objective correlates of anorexia of malignancy were studied. Decreased taste was reported by 25 patients, and an aversion for meat was reported by 16 patients. The decreased taste symptom correlated with an elevated taste threshold for sweet (sucrose), and the symptom of meat aversion correlated with a lowered taste threshold for bitter (urea). The likelihood of having a taste abnormality increased with increasing extent of disease, but not with histologic type of neoplasm. Patients with an abnormality of taste had an increased incidence of weight loss compared with patients with normal taste, even though many in the latter group had other causes of weight loss. These observations suggest that an abnormality of taste may be one determinant of the anorexia of malignancy. Better understanding of the anorexia in the cancer patient may contribute to the care of the patient.

Posthypophysectomy taste abnormalities: their relationship to remote effects of cancer.

Abnormalities in taste sensation have been studied in 15 patients consisting of five normal controls, five patients with diffuse neoplasm and five patients post hypophysectomy. Threshold recognition for salt and HC1 in the three groups studied was the same. Sucrose and urea recognition was higher in patients with neoplasm as compared to normal controls. Patients post hypophysectomy had a lower threshold recognition for sucrose than both normal individuals and patients with neoplasm. The threshold recognition has markedly shifted for both sucrose (decreased) and urea (increased) post hypophysectomy. These observations are in support of previous findings and suggest that the pituitary plays at least a necessary permissible factor in the development of abnormalities in taste as observed in patients with disseminated cancer.

Loss of taste in the elderly: sex differences.

The sensation of taste was tested in 280 normal people of all ages and both sexes. The sensitivity for the basic tastes decreased with increasing age, but more in men than in women; there was no sex difference in people under the age of 40. The different smoking habits of men and women did not explain this finding. It is suggested that there is a sex-specific decrease in the taste sensitivity with aging.

Taste alterations in liver cirrhosis: are they related to zinc deficiency?

Patients with chronic liver disease may have taste impairment and altered zinc metabolism. We evaluated Taste Detection Thresholds (TDTs) in 60 patients with liver cirrhosis and correlated the findings with disease severity and alcoholic etiology. Plasma zinc levels and urinary output were also measured. A placebo-controlled treatment trial with zinc sulphate was made in 15 patients with compensated cirrhosis in order to ascertain whether zinc deficiency caused taste alterations. Taste detection of salty, sweet and acid tastants was significantly impaired in all cirrhotic patients in comparison with normal subjects. TDTs were not influenced either by the etiology or the severity of the disease. All groups of patients had low plasma zinc levels and decompensated cirrhosis had a significantly increased urinary output of zinc. No correlation was found between taste acuity and plasma zinc levels when only cirrhotic patients were considered. The effect of zinc supplementation on TDTs did not appear to be inferior to that of the placebo. Our results indicate that taste impairment in cirrhotics is due to the disease process per se and not to zinc deficiency.
