A Hyaluronic Acid-Based Gel Ameliorates Wound Bed Appearance of Acute and Chronic Wounds: Prospective, Multicentric Clinical Investigation.

The aim of this study was to assess the performance and safety of daily treatment with a 0.2% hyaluronic acid-based hydrogel (Hyalo4 Skin Gel) in patients with chronic and acute wounds. The primary endpoint was the amelioration rate after 14 days of treatment, defined as the percentage of patients showing improvement in at least one of the following wound characteristics: wound tissue type, exudate amount, or type. Secondary endpoints included assessments of the treatment's effects on wound bed type, exudate amount and type, and patients' quality of life (EQ-5D QoL), as well as its safety and ease of application. Data were collected up to 56 days of treatment. A total of 170 patients were enrolled. Wound bed amelioration was observed in 46.0% of the patients after 14 days. The amelioration rate increased from 0.291 after 7 days to 0.561 after 56 days. The treatment promoted wound healing, increased granulation tissue formation, and normalized exudate levels. Additionally, QoL significantly improved, and the product was deemed easy to apply and safe, with no serious treatment-related adverse events reported. Being effective in enhancing the re-epithelialization of both acute and chronic wounds, Hyalo4 Skin Gel emerges as a promising strategy, improving clinical outcomes across a wide range of patients.
