Patterns of sensitization among dental healthcare workers in South Africa
| Allergic sensitization | Prevalence (%) |
|---|---|
| Atopy (Phadiatop positive) (n = 421) | 193 (46%) |
| Latex (k82) (n = 421) | 41 (10%) |
| Recombinant latex allergens (n = 85) | |
| - Hev b 1 | 0 (0%) |
| - Hev b 3 | 0 (0%) |
| - Hev b 5 | 3 (4%) |
| - Hev b 6.01 | 10 (12%) |
| - Hev b 6.02 | 6 (7%) |
| - Hev b 8 | 12 (14%) |
| - Hev b 9 | 1 (1%) |
| - Hev b 11 | 2 (2%) |
| CCD markers | |
| - MUXF3 | 13 (15%) |
| - HRP | 18 (21%) |
| True latex sensitization1 | 29 (7%) |
| Chloramine T (n = 69) 2 | 2 (0.5%) |
CCD – cross-reacting carbohydrate determinants; MUXF3 – Bromelain; HRP – horse radish peroxidase
True latex sensitization refers to positive response to latex (k82) and negative response to CCDs.
Only subjects who reported work-related allergic symptoms were tested.
