Self-Reported Impaired Wound Healing in Young Adults and Their Susceptibility to Experiencing Immune-Related Complaints

The current study examined to what extent individuals with wound infection (WI group), slow healing wounds (SHW group), or both (COMBI group) report poorer immune fitness and whether they experience immune-related complaints more often as compared to healthy participants (control group). Survey data from 3613 Dutch students was re-analyzed. Compared to the control group, perceived immune fitness was significantly lower by the SHW group (p < 0.001) and the COMBI group (p < 0.001), but no difference was found for the WI group (p = 0.059). Also, perceived immune fitness of the COMBI group was significantly worse compared to the WI group (p = 0.040). Compared to the control group, reduced immune fitness was reported to be significantly more frequently by the SHW group (p < 0.001) and the COMBI group (p < 0.001). Reduced immune fitness was significantly more common for the COMBI group compared to the SHW group (p = 0.011) and WI group (p = 0.001). Immune-related complaints such as headache, runny nose, coughing, sore throat, diarrhea, flu, and fever were significantly more frequently reported by individuals with impaired wound healing. The effects were most pronounced in the COMBI group, followed by the SHW group and a lesser extent the WI group. A highly significant correlation was found between perceived immune fitness and the percentage of individuals that reported impaired wound healing. In conclusion, the findings confirm that poorer immune functioning is characteristic for individuals with impaired wound healing. In follow-up studies, immune biomarkers analyses are needed to support patient-reported outcome measures.
