RESUMEN
INTRODUCTION: Actinic keratosis is a common skin disease that occurs in response to prolonged exposure to ultraviolet radiation. This problem affects up to 60% of the population over 40 years of age. Actinic keratosis is considered to be a precancerous lesion leading to squamous cell carcinoma (SCC). The new therapeutic option for the treatment of actinic keratosis is ingenol mebutate gel (0.015%, 0.05%). AIM: Retrospective evaluation of response and potential side effects of ingenol mebutate treatment in clinical practice. MATERIAL AND METHODS: Eight patients with actinic keratosis lesions on the face or scalp self-applied a 0.015% gel for 3 consecutive days on the 25 cm2 marked area. They were assessed at baseline and on day 4, 7, 14 and 57. RESULTS: All patients on day 57 presented a complete absence of AK lesions in the area of ingenol mebutate application. No adverse events were observed. CONCLUSIONS: Our study shows that ingenol mebutate is highly efficacious field treatment for actinic keratosis.
RESUMEN
INTRODUCTION: Omalizumab (Xolair) originally intended to reduce symptoms of moderate to severe asthma uncontrollable with steroids is the first monoclonal antibody approved for treatment of chronic spontaneous urticaria in 2014. AIM: To evaluate response and potential side effects to omalizumab treatment in clinical practice. MATERIAL AND METHODS: Eleven patients (6 males and 5 females) were recruited into the study. All participants signed written informed consent before enrollment to the study. At the beginning they were receiving 300 mg of omalizumab in a subcutaneous injection every 4 weeks in an outpatient clinic. Five the clinical response was sufficient, the dose of omalizumab was decreased to 150 mg. We evaluated response to the treatment using the Urticaria Activity Score in the last 7 days and the Urticaria Control Test at certain time points. RESULTS: Nine out of 11 patients achieved complete syndrome resolution. Five patients achieved clinical remission after the first dose of omalizumab. Mean time to remission was 9.3 weeks. During the study, no side effects were observed. CONCLUSIONS: Omalizumab appears to be a safe drug, which in a quick and effective way inducts remission in patients who have not responded to previous treatment.
