Exosome and Mesenchymal Stem Cell Treatment for Salivary Gland Dysfunction in Primary Sjögren Syndrome
Effect of Exosome and Mesenchymal Stem Cell Injections Into the Submandibular Glands on Salivary Gland Function in Primary Sjögren Syndrome: A Randomized Controlled Clinical Trial
This study will evaluate the effects of exosome and mesenchymal stem cell injections into the submandibular glands of adults with primary Sjögren syndrome and salivary gland dysfunction or dry mouth. A total of 30 participants will be randomly assigned to three groups: an exosome group, a mesenchymal stem cell group, or a placebo group. Both submandibular glands will receive two applications, with the second application performed 2 weeks after the first. Each gland will receive 0.5 mL of the assigned treatment at two injection sites. Exosomes will be derived from umbilical cord-derived mesenchymal stem cells, and mesenchymal stem cells will also be derived from umbilical cord tissue. The placebo group will receive saline. Previous sialoscintigraphy results obtained at Yeditepe University as part of the diagnosis of primary Sjögren syndrome will be used as the baseline assessment. The Xerostomia Inventory will be administered at months 1 and 3, and sialoscintigraphy will be repeated at month 6 to evaluate changes in salivary gland function. Each participant will be followed for 6 months.

実験的:Exosome
Participants will receive exosome injections into both submandibular glands. The exosome preparation is derived from umbilical cord-derived mesenchymal stem cells and contains 5 billion particles per 1 mL. Each submandibular gland will receive 0.5 mL at two injection sites per application. Two applications will be performed, with the second application 2 weeks after the first. |

実験的:Mesenchymal Stem Cells
Participants will receive mesenchymal stem cell injections into both submandibular glands. The mesenchymal stem cells are derived from umbilical cord tissue and produced by Yeditepe University at a concentration of 10 million MSCs per 1 mL. Each submandibular gland will receive 0.5 mL at two injection sites per application. Two applications will be performed, with the second application 2 weeks after the first. |

Change in Salivary Flow Rate From Baseline to Month 6 Assessed by Sialoscintigraphy
時間枠:Baseline to Month 6
|
Change in salivary flow rate, measured by salivary gland scintigraphy. Salivary flow rate will be expressed in mL/min. Baseline values obtained from the participants' existing sialoscintigraphy performed at Yeditepe University will be compared with the values obtained at Month 6. |
