Late taste disorders in bone marrow transplantation: clinical evaluation with taste solutions in autologous and allogeneic bone marrow recipients.

The aim of this work was to determine the type and the significance of taste disorders in allogeneic bone marrow transplanted patients. In a retrospective study the taste threshold of a cohort of 15 allogeneic bone marrow transplanted patients, 4-51 months after transplantation (mean: 30.6 +/- 15.8), was compared to the taste threshold of 8 autologous bone marrow recipients, 4-48 months after transplantation (mean: 24.12 +/- 12.18), and to the taste threshold of a group of 20 consecutive normal subjects. Allogeneic bone marrow transplanted patients showed a significant hypogeusia for salt (Pearson's chi square p = 0.0002; Yates' correction p = 0.0007) and sour (Pearson's chi square p = 0.001; Yates' correction p = 0.008). No significant variations were observed for sweet and bitter. Autologous bone marrow recipients did not show any significant variation of taste acuity for sweet, salt or sour; a constant reduction of the taste threshold for bitter was observed, but the values were not significantly different from normal (Pearson's chi square p = 0.47; Yates' correction p = 0.83). So, late and selective taste disorders are observed in allogeneic bone marrow transplanted patients. Since the severity of the disorders is not strictly related to the severity of chronic oral G.V.H.D., taste analysis could discover the slightest, clinically undetectable cases of chronic oral G.V.H.D. The mechanism of immune aggression on the sensorial taste cells is poorly understood. Further trials are needed to define variations of taste acuity not only after allogeneic bone marrow transplantation, but also in systemic immune diseases.

[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.

Dietary evaluation of patients with smell and/or taste disorders.

The impact of smell and taste disorders on dietary habits and nutritional status has received limited research attention. This paper reports findings obtained from questionnaires and diet records completed by 40 healthy subjects and 118 patients with chemosensory dysfunction. Chemosensory disorders were frequently associated with decreases in food acceptability. Although dietary responses to these dysfunctions varied greatly, patients with distorted or phantom smell and/or taste sensations tended to report weight loss whereas those with simple sensory loss were more likely to report weight gain. Indices derived from diet records did not indicate that either group of patients was at substantial nutritional risk, but food frequency responses and estimates of body mass index were consistent with patient reports of changes in dietary patterns and weight. In addition, marked weight change and aberrant dietary practices were noted in individual patients. Thus, there were indications that chemosensory dysfunction may be associated with nutritionally important dietary alterations.

A double-blind study of the therapeutic efficacy of zinc gluconate on taste disorder.

The therapeutic efficacy of orally given zinc gluconate on taste disorder was investigated by a double-blind study in 98 patients with a chief complaint of this disease. The subjects were divided into two 49-patient groups and were orally given zinc gluconate or the placebo for up to 4 months. Improvement of taste examination and subjective symptoms was analyzed in 65 of the subjects. Although no significant difference was detected between the two groups in overall efficacy, a significant superiority of zinc gluconate to placebo was observed in patients with idiopathic and zinc-deficient taste disorder. Comparison of the improvement by Ridit analysis showed a significant therapeutic superiority of zinc gluconate. In contrast, comparison of the degree of subjective symptomatic changes.

[Taste disorders in chromium exposed workers].

Taste thresholds were investigated by means of chemical and electric stimulation in order to prove the induction of taste disturbances by chrome dust. There were examined 46 persons with exposition by potassium bichromate, chromic acid and zinc chromate, 19 of them working under conditions of a lower chrome exposition level but 27 of them working under conditions of a higher chrome exposition level. We could find a increasing threshold in taste qualities "sweet", "poor", "salty" and "bitter" corresponding to an increase of chrome exposition on the one hand and likewise of electric stimuli on the other hand. The quantity of chrome exposition must be regarded more important than its quality and its duration. Finally we want to recommend the appliance of always as electrogustometry as chemogustometry for occupational taste investigations because both the methods seem to differ somewhat.

[Remarks on the systematization and terminology of smell and taste disorders].

Based on the experience of the Olfactogustometry Laboratories in Halle and in Poznan, a proposal of clinical terminology and systematization of smell and taste disorders has been presented. Individual interpretation of the data from anamnesis in relation to the findings of the olfactogustometric investigations were stressed as indispensable.

Smell and taste disorders, a study of 750 patients from the University of Pennsylvania Smell and Taste Center.

Smell and taste disorders are common in the general population, yet little is known about their nature or cause. This article describes a study of 750 patients with complaints of abnormal smell or taste perception from the University of Pennsylvania Smell and Taste Center, Philadelphia. Major findings suggest that: chemosensory dysfunction influences quality of life; complaints of taste loss usually reflect loss of smell function; upper respiratory infection, head trauma, and chronic nasal and paranasal sinus disease are the most common causes of the diminution of the sense of smell, with head trauma having the greatest loss; depression frequently accompanies chemosensory distortion; low body weight accompanies burning mouth syndrome; estrogens protect against loss of the sense of smell in postmenopausal women; zinc therapy may provide no benefit to patients with chemosensory dysfunction; and thyroid hormone function is associated with oral sensory distortion. The findings are discussed in relation to management of patients with chemosensory disturbances.

Taste disorder in hypo and hyperthyroidism.

Gustatory responses to the basic taste substances (sweet, salty, sour and bitter) were studied in hypothyroid and hyperthyroid subjects. The intensity and hedonic responses were evaluated using "category scaling" for 7 concentrations of glucose, sodium chloride, citric acid and quinine sulphate. The intensity and hedonic values decrease in hyperthyroidism for salt and bitter solution, and sourness is perceived as more unpleasant. In hypothyroid subjects intensity and hedonic value decreases for sweetness, the pleasant responses to salt and bitter increase, though intensity perception decreases for bitter solutions.

[Taste disorders and liver parenchymal damage after administration of thiamazole (author's transl)].

Marked, and in some cases long-lasting, taste disturbances occurred in three patients on thiamazole. In addition, all three had a rise in serum transaminases and alkaline phosphatase levels, due to associated liver parenchymal damage. Cause of these changes was the high thiamazole dosage (160 and 120 mg/d). Reduction in dosage restored normal taste sense in all three, but in two the drug had to be discontinued because of persisting high transaminase levels.
