RESUMEN
The purpose of the study is to evaluate the clinical effects of Mucosamin® (a spray preparation containing sodium hyaluronate combined with a pool of amino acids of precursor collagen, including L-Proline, L-Leucine, L-Lysine and glycine) on wound healing and pain management of oral mucositis after hematopoietic stem cell transplantation. The importance of professional dental hygiene by dental hygienist in reducing the severity of oral mucositis as unique therapy or in addition to therapy with Mucosamin® was also evaluated. One hundred thirty-seven patients undergoing hematopoietic stem cell transplantation were recruited in a case-control study and divided into 4 groups: Group A: professional oral hygiene + Mucosamin®; Group B: professional oral hygiene + standard treatment with chlorhexidine 0.20%;; Group C: only Mucosamin®; Group D: only standard treatment with chlorhexidine 0.20%. The following evaluations were made: WHO mucositis scale, OMAS mucositis scale, VAS, periodontal recording, days of mucositis. Comparing the groups at the onset of OM on WHO scale, it was observed that Group A grade 1 occurrence was more statistically significant than Group B (p= 0.03*); comparison between Group A and D showed a statistically significant difference in favour of Group A (p= 0.0002*). Also OMAS scale showed a statistically significant difference between groups who assumed Mucosamin, who developed lower OM grade (p = 0.001*). There was a statistically significant difference between group A compared with group B over the overall duration of OM (p = 0.02*), as well as between group A and group D (p=0.03*). According to the present study the combination of a careful debridement, correct oral hygiene during hospitalization and the use of Mucosamin® exponentially reduces the severity and duration of mucositis and consequently the discomfort of the patient. Moreover, it can be stated that the use of Mucosamin® also results in a reduction in the extent of chemotherapy lesions. Hyaluronic acid and amino acid-based sprays can be a valuable therapeutic aid in the treatment of mucositis.

Oral mucositis (OM) may occur in up to 100% of patients undergoing condition regimen to hematopoietic stem cell transplant (HSCT). From the patients perspective, OM is one of the most debilitating side effects of transplantation. It is commonly thought that oral hygiene can modify the incidence and severity of oral mucositis, therefore professional oral health care (POHC) is recommended prior to conditioning regimen for HSCT. A new strategy for the treatment of OM is sodium hyaluronate (SH) combined with amino acid precursors of collagen (Aas) (Mucosamin®). SH is a mucoaderent polymer acting as a mechanical barrier and pain reliever. Furthermore, it allows prolonged contact of the product with the mucous membrane. In this study, a total of 68 adult patients due to undergo HSCT for allogenic and autologous transplant were enrolled at the Stem Cell Transplant Unit. The patients were divided into two groups. One group was treated with POHC before HSCT and applications of Mucosamin® during the recovery after transplantation. The second group served as controls, with the usual treatment of Clorexidine 0.20% adopted by the department. After HSCT the same clinician, an expert in oral medicine trained for the clinical trial, evaluated symptoms of the patients mucositis of both groups every day. The treated patients developed less severe OM, therefore Mucosamin® seems to have a protective role against the more severe phases of mucositis. The maximum OM pain, measured with the VAS scale, was higher in patients who did not use Mucosamin®. In the treated group OM resolved sooner than in the control group.
