DENVER – Oral low-dose isotretinoin in combination with pulsed dye laser achieves high percentage of papulopustular rosacea clearance with a low risk of side effects, results from a single-center study found.
“Rosacea has been classically treated with topical and oral antibiotics, retinoids or ivermectin, and it is really important to enhance laser contribution for rosacea clearance,” lead study author Natalia Jiménez Gómez, MD, said in an interview in advance of the annual conference of the American Society for Laser Medicine and Surgery. “Our work points to the high efficacy of a scarcely published combination treatment: low-dose oral isotretinoin and pulsed dye laser. Moreover, this combined treatment is employed in papulopustular rosacea, a clinical form that is usually treated without employing physical methods.”
For the study, Dr. Gómez and her colleagues retrospectively analyzed 40 patients with moderate or severe papulopustular rosacea who underwent concomitant treatment of pulsed dye laser and low-dose oral isotretinoin (5-10 mg/day). Pulsed dye laser sessions were performed with a 10-mm spot size at a pulse duration of 0.5 milliseconds delivered at a fluence of 8 J/cm2 every 3-4 weeks in combination with low-dose oral isotretinoin during 4- to 6-month periods. The treatment endpoint was purpura. Five patients were withdrawn from the analysis because of loss to follow-up or to a lack of clinical images.
All 35 patients achieved a complete clearance of papulopustular lesions of rosacea within 7-10 days, said Dr. Gómez, who practices at the Madrid-based Hospital Universitario Ramón y Cajal. The researchers did not observe any permanent adverse events such as scarring, hyperpigmentation, or hypopigmentation.
“The most surprising finding was the high percentage of rosacea clearance obtained with the combined treatment, considering that all the patients were previously nonresponsive to oral low-dose isotretinoin monotherapy,” Dr. Gómez said. “This finding highlights the important role of pulsed dye laser.”
She acknowledged certain limitations of the study, including its retrospective design and small sample size. “It would also be interesting to compare pulsed dye laser with intense pulsed light, so that we can conclude if one of them is more effective than the other when we combine it with low dose oral isotretinoin,” she said.
Dr. Gómez reported having no financial disclosures.
