Abstract
Aims: Impaired wound healing causes chronic ulcers in Hansen’s disease (HD) patients which are an unrecognized clinical manifestation and requires utmost care and attention for wound management. Collagen and chitosan biopolymers when synergistically combined produce a biologically active biomaterial for wound dressings. Hence, the aim was to prepare a collagen/chitosan (COL/CS) composite and characterize for wound healing potential in HD patients.
Place and Duration of Study: CSIR-Central Leather Research Institute, Sardar Patel Road, Adyar, Chennai 600021, Southern Railway Headquarters Hospital, Constable Road, Ayanavaram, Chennai 600023, and Gremaltes Hospital, India between June 2013 and July 2020.
Methodology: The HD wounds were measured by Planimetry in square cm and were also assessed for morphological structure of epidermis and collagen fiber arrangement by High Resolution- Scanning electron microscopy (HR-SEM). Proton Nuclear magnetic resonance spectroscopy (1H-NMR) for metabolite identification was studied in blood plasma samples of unwounded, untreated and treated HD patients
Results: Size D (wound size on day of discharge) of the wounds were appreciably lower than Size 0 (wound size before biomaterial treatment) demonstrating efficient wound healing by the biomaterial. The morphological structure of the HD wounds showed healthy epidermal layer and thick fibers of collagen matrix in the treated wounds when compared to the controls. Key metabolites of metabolic pathways such as TCA cycle, creatine cycle and protein metabolism were identified by 1H-NMR spectroscopy
Conclusion: The COL/CS wound dressing is a promising biomaterial for management of chronic wounds in Hansen’s disease.
