Pain induced by photodynamic therapy of warts

BACKGROUND: Photodynamic therapy with topical 5-aminolevulinic acid (ALA), followed by irradiation with red light (ALA-PDT), is used for non-melanoma skin cancer and other dermatological diseases. Pain during and after light exposure is a well-known adverse advent that may be a limiting factor for treatment, particularly, in viral warts. METHODS: To assess the pain induced by ALA-PDT, we asked 45 patients enrolled in a randomized, placebo-controlled trial with six consecutive ALA- and placebo-PDT treatments for recalcitrant foot and hand warts to fill in questionnaires about pain immediately and 24 h after each treatment. RESULTS: Immediately and 24 h after each of the six treatments, pain intensity was significantly higher in warts treated with ALA-PDT than in warts treated with placebo-PDT (P<0.028). Severe or unbearable pain was reported from a median of 17% (6-31%) of the ALA -treated warts and from a median of 2% (0-15%) from the placebo-treated warts immediately after the treatments. With increasing treatments, no significant change in pain intensity was observed and no significant relation was found between the pain intensity and the relative change in wart area. The pain was primarily characterized as burning and shooting. The pain lasted about 30 h (range: 1-96 h). CONCLUSION: We conclude that pain induced by ALA-PDT is of such intensity in about one-fifth of the warts that pain relief is indicated.

Recalcitrant hand and foot warts successfully treated with photodynamic therapy with topical 5-aminolaevulinic acid: a pilot study

The purpose of this pilot study was to determine if photodynamic therapy with topical application of 5-aminolaevulinic acid followed by irradiation with incoherent filtered and unfiltered light (ALA-PDT) is an effective therapy for recalcitrant hand and foot warts. In 30 patients with recalcitrant warts, 49 regions with a total of 250 warts were randomized to one of the following five treatments: (i) ALA-PDT with white light applied three times within 10 days (W3); (ii) ALA-PDT with white light applied once (W1); (iii) ALA-PDT with red light applied three times within 10 days (R3); (iv) ALA-PDT with blue light applied three times within 10 days (B3), and (v) cryotherapy applied up to four times within 2 months (CRYO). The ALA-PDT treatment modality was repeated in case of partially responding warts. Significantly more warts were completely healed after W3 and W1 than after R3, B3 and CRYO (P < 0.01): 73% of the warts treated with W3 were completely healed, 71% after W1, 42% after R3, 23% after B3 and 20% after CRYO. No scars were observed in the ALA-PDT treated areas and patients treated for foot warts were all able to walk after the treatment. No recurrences in completely responding ALA-PDT treated warts were observed after 12 months of follow-up. In conclusion, photodynamic therapy with topical 5-aminolaevulinic acid followed by irradiation with white light is a promising treatment for recalcitrant hand and foot warts.

Comparative study of photodynamic therapy vs CO2 laser vaporization in treatment of condylomata acuminata: a randomized clinical trial

BACKGROUND: Most conventional therapies for condylomata acuminata (CA) are traumatic and have high recurrence rates. OBJECTIVES: To investigate the efficacy and safety of topical application of 5-aminolaevulinic acid (ALA) photodynamic therapy (PDT) for the treatment of CA. METHODS: Sixty-five patients with CA were allocated into the treatment (ALA-PDT) group and treated with 20% ALA solution under occlusive dressing for 3 h followed by irradiation with the helium-neon laser at a dose of 100 J cm(-2) and a power of 100 mW. Another 21 CA patients were allocated into the control group and treated with the CO(2) laser. The treatment was to be repeated 1 week later if the lesion was not completely removed after the first treatment. RESULTS: After one treatment, the complete removal rate was 95% in the ALA-PDT group and 100% in the control group. After two treatments with ALA-PDT, the complete removal rate in the treatment group was 100%. The recurrence rate for ALA-PDT group was 6.3% which was significantly lower than that in control group (19.1%, P < 0.05). Moreover, the proportion of patients with adverse effects in the ALA-PDT group (13.9%) was also significantly lower than that in control group (100%, P < 0.05). The side-effects in patients treated with ALA-PDT mainly included mild burning and/or stinging restricted to the illuminated area. CONCLUSIONS: The present study shows that topical application of ALA-PDT is a simpler, more effective and safer therapy with a lower recurrence for treatment of CA compared with conventional CO(2) laser therapy.     

光动力联合电灼治疗尖锐湿疣222例

【摘要】 目的 观察5-氨基酮戊酸光动力疗法（ALA-PDT）治疗尖锐湿疣(CA)的临床疗效,以及ALA-PDT治疗后复发率与人乳头瘤病毒（HPV）分型（高危型、低危型）的关系。方法 电灼组：87例,用电灼去除疣体;联合组：90例,先用电灼去除疣体,再续以每周1次共4次的ALA-PDT治疗;ALA-PDT组：103例,只给予每周1次,共4次ALA-PDT。其中治电灼组、联合组进行HPV DNA检测,将其分为高危型和低危型两组。结果 电灼组、联合组以及ALA-PDT组的治愈率、复发率分别为100%、66.67%,100%、8.89 %,68.93%、21.13%;三组的治愈率与复发率均进行两两比较,差异均具有统计学意义（P<0.05）（除电灼组与联合组相等外）。电灼组的高危型、低危型复发率分别为85.71%、58.62%,两者差异有统计学意义（P<0.05）;联合组高危型和低危型复发率分别13.04%、8.33%,差异无统计学意义（P>0.05）。结论 电灼和联合组治愈率相同且高于单纯ALA-PDT组,电灼复发率最高,联合组复发率最低,单纯ALA-PDT组副作用最小;光动力疗法可能对HPV高危亚型更敏感。
