Background
Taste alteration of bitter, sour, sweet, salty and umami test are common, identification of patients with altered taste perception could reach to implement strategies and to prevent or improve malnutrition. There is not information regarding the change of taste perception after renal transplantation, and the association of taste change with nutritional status.
Methods
Prospective cohort in receptors of 1st transplant (Jan-Oct 2022). Subjects with dental prostheses, oral alterations, and active infection were excluded. The sample was 47 patients, and only 21 have completed the evaluation after the transplant. Subjective global assessment, pica questionnaire, current medications, and taste perception test. Anthropometric measurements were taken.
Results
Forty seven patients were inlcuded, 38.8 years old (mean); 70% were male, 51% had unknown cause of ESRD, 51% had hemodialysis, 43% peritoneal dialysis and 6% early trasplant.
Conclusion
There is a beneficial effect of kidney transplant on the sense of taste and nutritional status.
Patients with indicators of adiposity have an alteration of taste before the KT.
The umami taste significantly increases the perception of intensity, and the sour taste presents a not significant trend, this after renal transplantation, despite that almost all taste intensities increases.
Patients who present BMI 25-30 kg/m2 before the transplant decrease significantly after the transplant and muscle mass indicators (AMA) present a trend.
