Laboratory assessment of the efficiency of encasing materials against house dust mites and their allergens

Background: The current recommendation to reduce mite allergen exposure for mite‐sensitive individuals is to use allergen‐impermeable bed coverings. As these covers are made of various kinds of materials, they vary in quality. The objective of this study was to investigate the efficiency of differen...

Description
Summary:Background: The current recommendation to reduce mite allergen exposure for mite‐sensitive individuals is to use allergen‐impermeable bed coverings. As these covers are made of various kinds of materials, they vary in quality. The objective of this study was to investigate the efficiency of different covering materials against house dust mites and their allergens in vitro. Methods: Four types of materials including (1) plastic cover, (2) polyurethane‐coated cover, (3) non‐woven covers, (4) tightly woven microfiber covers and a regular cotton bed sheet (as a control) were evaluated using three methods: (i) heat escape method, (ii) Siriraj chamber method and stereomicroscopy, scanning electron microscopy and (iii) enzyme‐linked immunosorbent assay (ELISA). Results: We found that there was a statistically significant difference in allergen permeability among four types of coverings (P
