Cellular activity in the dermis surrounding the hair bulb in alopecia areata.

Pierard GE, De la Brassinne M.

The metabolic activity of the cells in the connective tissue surrounding the hair bulb has been studied by radioautography in alopecia areata and in normal scalp, using in vitro incorporation of tritiated thymidine, uridine, histidine, leucine and proline. In alopecia areata, the hair bulbs are blocked in the anagen IV stage and DNA, RNA and protein synthesis are restrained. Cells in the papilla, as well as the cellular infiltrate, display a very low rate of metabolic activity. During regrowth in alopecia areata, the activity of endothelial cells is increased in the papillary and peribulbar layers before DNA, RNA and protein synthesis are restored in the epithelial cells of the hair bulb. The dermal and epithelial labelling patterns eventually reach levels comparable to those observed in an induced anagen IV state of a normal scalp. It is concluded that the progression from anagen IV to a further stage represents a critical period in the growth of hair that would closely depend upon an adequate metabolic function of the connective tissue. It is impaired in alopecia areata.

BACKGROUND: Several laser systems with varying wavelengths, pulse durations, and energy fluences are currently utilized for hair removal. However, the ideal laser parameters and treatment candidates for photoepilation remain largely unknown. The medical literature lacks a wealth of experimental data to sufficiently document the long-term safety and efficacy of laser-assisted hair removal. This study examines the clinical efficacy and side effect profile of long-pulsed alexandrite laser-assisted hair removal utilizing laser pulse durations of either 5, 10, or 20 milliseconds (ms). STUDY DESIGN/METHODS: Laser-assisted hair removal was performed on 36 subjects with a long-pulsed alexandrite laser. Areas of unwanted hair growth on the face, back, and legs were divided linearly into four 1 cm2 or 2 cm2 quadrants. Experimental regions included a control quadrant and three additional quadrants, which were treated with the alexandrite laser using an average fluence of 18 J/cm2, with a 10 mm spot size at either a 5, 10, or 20 ms pulse duration. Hair counts and photographs were obtained before treatment, immediately following irradiation, 1 week and 1, 3, and 6 months postoperatively. RESULTS: All laser-treated quadrants displayed a significant delay in hair regrowth compared to control nontreated quadrants at postoperative week 1 and months 1 and 3. Hair counts were reduced by 66% at 1 month, 27% at 3 months, and 4% at 6 months. No significant differences in clinical efficacy or side effect profiles were observed between treatment quadrants, yet a trend towards less post-treatment erythema and hyperpigmentation was noted with the 20 ms pulse duration. CONCLUSIONS: Equivalent long-term hair removal for up to 6 months was achieved with the long-pulsed alexandrite laser at 5, 10, and 20 ms pulse durations at an average fluence of 18 J/cm2. Side effects were limited and transient.

Busulphan/cyclophosphamide conditioning for bone marrow transplantation may lead to failure of hair regrowth.

Following the introduction of bulsulphan and cyclophosphamide (BUCY) conditioning in our unit in 1987, a number of patients noted incomplete scalp hair regrowth following bone marrow transplantation (BMT). Between August 1987 and May 1989, 22 patients had undergone allogeneic or autologous BMT in our unit and we recalled for detailed assessment the 14 who were alive and well at least 6 months post grafting. Six patients had experienced incomplete hair regrowth of varying severity 7-27 months following BMT. All those affected had received BUCY conditioning and the four most severely affected were allogeneic BMT recipients. No patient had received any post-BMT chemotherapy or radiation. None of the patients had evidence of graft-versus-host disease. No laboratory test abnormalities distinguished the affected from the unaffected patients. Despite the relatively small number of patients, our results suggest that BUCY has caused permanent damage to the hair follicles of the affected patients. Prolonged alopecia may markedly impair the quality of life for long-term survivors of BMT and this unexpected complication also has significant medicolegal implications.
