Abstract
PICO QUESTION: In cats with chronic gingivostomatitis, does using intravenous mesenchymal stem cell therapy, compared to not using it, lead to the improvement of clinical signs? CATEGORY OF RESEARCH: Treatment. NUMBER AND TYPE OF STUDY DESIGNS REVIEWED: Five interventional studies (clinical trials). STRENGTH OF EVIDENCE: Moderate. OUTCOMES REPORTED: The reviewed studies indicate intravenous mesenchymal stem cell (MSC) therapy is safe to administer and can be effective in remission or alleviating the clinical signs of refractory, chronic gingivostomatitis in cats that have undergone full-mouth tooth extraction. CONCLUSION: The collective evidence supports the intravenous administration of mesenchymal stem cell (MSC) therapy in cats with chronic gingivostomatitis following dental extraction. However, conducted clinical trials are prone to different degrees of bias due to the lack of independent control groups, the small number of subjects, and enrolling subjects with various severity of the disease. Therefore, more robust evidence can be obtained through well-designed randomised controlled trials to confirm the observed positive effects of the treatment in cats with a broader range of characteristics.
