Efficacy Study of a Ginger and Cardamom Gelatin for Xerostomy in Terminally Ill Patients

Study Overview
=================
Brief Summary
-----------------
Xerostomia or dry mouth is the subjective feeling that there is not enough saliva in your mouth. It's a frequent symptom in terminally ill patients receiving palliative care, reducing their quality of life and comfort. Usual recommendations in these patients are good oral hygiene and mouthwashes, ad libitum consumption of camomile and lemon juice infusions, and ad libitum sucking of cold (e.g. ice, ice cream) or citric products (e.g. pineapple). Other xerostomia treatments such as artificial saliva and pharmacological drugs (e.g. pilocarpine) are less used in terminally ill patients due to cost and secondary effects. The purpose of this randomized parallel clinical trial is to determine if a new recipe of gelatin with orange juice, cardamome and ginger is more effective in the control of xerostomia than the usual treatment of camomile infusion with lemon juice against. Treatments will be consumed ad libitum during one week. The main outcome is the subjective assessment of dry mouth at end of treatment.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cardamom, ginger and orange juice gelatin<br>Dietary Supplement | Dietary Supplement: Cardamom, ginger and orange juice gelatin<br>* Patients will receive the recipe of the gelatin, with detailed instructions to prepare it at home, and the necessary ingredients for the gelatin. If necessary, they will be helped in the preparation of an initial batch that should last for one week of treatment. Patients will be instructed to consume the gelatin candy as necessary to alleviate the dry mouth sensation<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Scale of self-perceived mouth dryness (0=not at all, 10=very dry) |  | At end of treatment (1 week ) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective signs of xerostomia | Investigator will assess the presence of xerostomia signs through the assessment of 1) appearance and degree of dryness of tongue, buccal mucosa and lips, and 2)difficulties in speech derived from dry-mouth sensation in the patient. | At end of treatment (1 week ) | 
| Scale of subjective assessment of salival disfunction (Pai 2001). |  | At end of treatment (1 week ) | 
| Treatment acceptability | Participants will answer an open-question regarding their satisfaction with the treatment received, with regards to taste, texture, difficulty of preparation, etc. | At end of treatment (1 week ) |
