Autologous noncultured melanocyte transplantation for stable vitiligo: can suspending autologous melanocytes in the patients' own serum improve repigmentation and patient satisfaction?
BACKGROUND
Vitiligo is a cosmetically disfiguring acquired depigmenting disorder caused by the loss of functional melanocytes from the epidermis. Various approaches that have been used for the treatment of vitiligo can be classified as medical and surgical therapies. Noncultured autologous melanocyte transplantation is a new and effective surgical treatment for stable vitiligo.


OBJECTIVE
To compare the repigmentation results in stable vitiligo of transplantation of autologous noncultured melanocytes suspended in normal saline with that of those suspended in the patient's own serum.


METHODS
Twenty-five patients with 36 lesions of stable vitiligo were randomized into two groups for noncultured melanocyte transplantation. Patients in Group A received melanocytes suspended in normal saline, and those in Group B received melanocytes suspended in their own serum.


RESULTS
Statistically significant difference in repigmentation results and reduction in Dermatology Life Quality Index (DLQI) score was observed between the two groups 16 weeks after surgery. Repigmentation results were excellent (>90%) and very good to excellent (>75%) in 44.4% and 66.7% of lesions, respectively, in Group A and 88.8% and 94.4% of lesions, respectively, in Group B. There was also a significant (p=.002) decline in DLQI score in both groups, with the mean reduction being significantly greater in Group B than Group A (p=.005).


CONCLUSIONS
Results of noncultured melanocyte transplantation can be improved significantly more by suspending the melanocytes in the patients' autologous serum than in normal saline. This could be an important innovation in the surgical management of patients with stable vitiligo.
