Salivary Proteins in Disease and Health

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will examine saliva samples from healthy volunteers and patients with various diseases to learn more about how disease affects the mouth and salivary glands. It will use a method called salivary proteomics to identify multiple proteins in saliva and discover if there are protein patterns unique to specific diseases. The study will: * Characterize the salivary proteome in patients with Sjogren's syndrome, graft-versus-host disease, diabetes, sarcoidosis, cystinosis, dental caries, and immunodeficiencies and in patients who have had head and neck radiation * Evaluate the possible use of salivary proteomics for early diagnosis * Evaluate the potential use of salivary proteomics for prognosis and treatment Patients participating in NIH clinical studies who have Sjogren's syndrome, graft-versus-host disease, diabetes, sarcoidosis, cystinosis, dental caries, or an immunodeficiency, or patients undergoing head and neck radiation may be eligible for this study. Candidates are screened with a medical and dental history, head and neck examination, and photographs of any mouth sores or disease. Healthy volunteers also have blood drawn for routine laboratory testing. Participants have saliva collected from the floor of the mouth, the parotid salivary glands in the cheek, and the submandibular and sublingual salivary glands under the tongue. Patients with certain diseases also provide a urine sample. Saliva samples are collected as follows: * One time from healthy volunteers and patients with Sjogren's syndrome, diabetes, sarcoidosis, cystinosis and immunodeficiencies * Five times from patients undergoing stem cell transplant: at baseline before transplant and about 1, 2, 3 and 6 months after transplant. * Three times from patients undergoing head and neck radiation: at baseline before radiation and at 3 and 6 months after the conclusion of radiation.
