Background/Objectives: Cutaneous warts  (CW), or  verrucae,  are  benign  prolifera- tion   of  skin  that   result   from   infection   with   human   papilloma   viruses.   Cellular immune  reactivity  plays  a significant  role  in wart  regression. The  aim of this  study was  to  elucidate  the  cellular immune  status  of patients with  CW through measure- ments  of their  serum  levels of interleukin-17 (IL-17) and macrophage migration  inhi- bitory  factor  (MIF,) and,  identify  the  possible  role  of  IL-17  and  MIF in  CW.  We assessed serum  IL-17 and  MIF levels  in patients with  different forms  of  CW  and compare  the  results  with controls.

Patient and  methods: Serum  levels  of  IL-17 and  MIF were  measured using  com- mercially available ELISA assay kits in 60 patients with CW and 20 healthy  controls. Results:  Serum  levels  of  IL-17  and  MIF were  significantly  lower  in  patients  with CW when  compared with  the  controls  (P-value <.01, <.05, respectively).  There  was nonsignificant  correlation between IL-17 and MIF.

Conclusion:   Low IL-17 and  MIF levels may have  a contributory role in occurrence, maintenance,  severity,   and  recurrence  of  different  types   of  CW  which  depend mainly on the  defect  of cell-mediated immunity. This may shed  new  light on nontra- ditional strategies for the  future  medical treatments of CW through regulation  of IL-17 and MIF.
