Brief Summary

Cancer is one of the main causes of death globally, being in many countries the first cause of mortality. One of the main side effects of chemotherapy and/or radiotherapy treatment in cancer patients is the alteration of taste and smell, internationally known as these anomalies Taste Smell Alterations (TSA). These alterations are the result of an altered cellular structure, the presence of TSA is associated with reduced quality of life and poor nutrition, due to dietary changes made by these patients. Synsepalum dulcidicum (dried miracle berry, DMB) is a plant belonging to the Sapotaceae family, made up of around 800 species grouped into around 40 genera. It is an indigenous species to the forest regions of West Africa. Nuts of this specie have been approved as a novel food in accordance with Regulation (EU) 2015/2238 and at the request of the European Commission through the European Food Safety Authority (EFSA) Panel on Nutrition, Novel Foods and Food Allergens. The characteristic component of DMB is miraculin. Miraculin is a glycoprotein whose consumption causes acidic and sour foods, and to a lesser extent bitter, to be perceived as having a sweet taste. In this sense, it is possible that the consumption of DMB before each meal can improve sensory perception after treatment with chemotherapy or radiotherapy.

Outcome Measures

Primary Outcomes (4)

  • Electrogustometry

    In this test, perception thresholds are obtained by electrical stimulation (current in microamperes), administered in different tongue regions through small disc-shaped monopolar electrodes.Three areas of the tongue (fenced papillae, tongue apex, and soft palate) are stimulated on both the right and left sides in ascending order two at a time from -6 dB (4 mA) to 34 dB (400 mA). ) in intervals of 0.5, 1, 1.5 and 2 s. If the stimulus is not detected, a single stimulus will be performed at 36 dB and another at -6 dB, to which the subject must answer whether or not they have been able to detect the stimulus.

    Before chemotherapy, After therapy (3-4 days), Follow up (1 month, 2 months and 3 months after chemotherapy)

  • Sniffing Stick Smell Test

    Sniffing Sticks are markers filled with an odorous fragrance that when removed from the stick releases the smell.To perform all tests, the open pen is held approximately 2 cm in front of the nostrils and the subject is verbally warned to smell it (for example, by saying the number on the pen). The pens are labeled with red numbers from 1 to 16. If the patient hits less than 8 smells, it is considered that they have altered taste and smell

    Before chemotherapy, After therapy (3-4 days), Follow up (1 month, 2 months and 3 months after chemotherapy)

  • Strips' Test

    Test for the identification of taste deficiencies validated. This test uses spoon-shaped flavor-impregnated filter papers that allow them to be selectively applied to specific areas of the tongue. In this test, 4 flavors (sweet, salty, bitter and acid) are evaluated at 4 different concentrations. The sweet taste will be represented by sucrose (0.4, 0.02, 0.1, 0.05 g/mL), the acid by citric acid (0.3, 0.16, 0.09, 0.05 g/mL), the balance by sodium chloride (0.25, 0.1, 0.004, 0.016 g/dL) and quinine bitter (0.006, 0.0024, 0.0009, 0.0004 g/dL). A 1 is marked if the flavor is detected and a 0 if it is not detected. To obtain the global impression of the taste function, a taste score is performed based on the minimum concentration detected and the flavor used.

    Before chemotherapy, After therapy (3-4 days), Follow up (1 month, 2 months and 3 months after chemotherapy)

  • Taste and Smell Survey

    This test is used to explore the prevalence, characteristics, and severity of taste and smell changes in a disease. It is made up of 12 items, 7 of them related to taste and 5 related to smell. For each of the questions, 1 point will be assigned for each question answered negatively. An additional point will be awarded for mild/moderate or rarely/sometimes and 2 points for severe/disabling or often/always. Changes in taste were scored from 0 (no change) to 10 (multiple severe changes) and changes in smell from 0 (no change) to 5 (multiple severe changes).

    Before chemotherapy, After therapy (3-4 days), Follow up (1 month, 2 months and 3 months after chemotherapy)
