Successful treatment of recalcitrant granulomatous rosacea with oral thalidomide and topical pimecrolimus

Efficacy and safety of non-insulated fractional microneedle radiofrequency for treating difficult-to-treat rosacea: a 48-week, prospective, observational study

Rosacea is a common chronic facial inflammatory skin disease. However, treatment for "difficult-to-treat rosacea" cases has not been established. This 48-week, prospective, observational study analyzed patients who underwent three non-insulated fractional microneedle radiofrequency (NFMRF) sessions at 2-month intervals. Therapy efficacy, epidermal barrier function, and side effects were evaluated. 34 subjects completed the trial. NFMRF resulted in CEA score reduction from 2.65 ± 0.59 to 1.56 ± 0.50 (P < 0.001) and mean DLQI reduction from 16.70 ± 3.55 to 10.48 ± 2.92 (P < 0.001). The successes of CEA (44.12 vs. 2.94%), IGA (91.67 vs. 25.00%), and flushing (58.82 vs. 26.47%) were observed. Among 34 patients, 22 reported "excellent" or "good" improvement and 30 were "very" or "relatively" satisfied. Skin barrier results revealed that hemoglobin content significantly decreased from 376.47 ± 71.29 at visit 0 to 161.32 ± 52.86 at visit 3. 2 of 30 patients followed-up at 6 months had a relapse at 18 and 20 weeks, respectively. No serious side effects were observed. NFMRF alone results in visible improvement and has great efficacy for difficult-to-treat rosacea without compromising patient safety or damaging the skin barrier.

Topical calcineurin inhibitors as a double-edged sword in rosacea: A systematic review

BACKGROUND

Rosacea is a chronic inflammatory disease mainly with skin or ocular manifestations. Topical calcineurin inhibitors, pimecrolimus and tacrolimus, can be used to treat rosacea. However, they can also induce rosacea-like eruptions.

AIMS

This study systematically reviewed the double-edged sword effects of pimecrolimus and tacrolimus on rosacea.

METHODS

Four databases were retrieved to search for articles on the effects of pimecrolimus and tacrolimus on rosacea, including Cochrane Library, Embase, PubMed, and Web of Science. Only English articles were included in the systematic review. Relevant data were collected, and the levels of evidence were evaluated.

RESULTS

28 articles published between 2001 and 2016 were included. 11 articles were about pimecrolimus as the treatment of rosacea, 4 articles were about the pimecrolimus-induced rosacea, 9 articles were about tacrolimus as the treatment of rosacea, and 4 articles were about tacrolimus-induced rosacea. Participants for each study ranged from 1 to 200. Several types of outcome measurements were used for these publications.

CONCLUSIONS

Both pimecrolimus and tacrolimus might have double-edged sword effects on rosacea. Pimecrolimus and tacrolimus could be effective for rosacea. However, both of them could also induce rosacea. Larger, randomized, controlled studies on pimecrolimus and tacrolimus as the treatment of rosacea and studies on the mechanisms of pimecrolimus and tacrolimus in treating or inducing rosacea are needed. This systematic review emphasized the double-edged sword role of topical calcineurin inhibitors in rosacea, which may pave the way for future research.

[Facial manifestations of granulomatous diseases]

Clinical manifestations of granulomatous diseases are a recurring challenge in everyday dermatological practice. Clinical presentation and histological patterns are variable, depending on the particular disease. Knowledge about the differential diagnosis of granulomatous changes in the face is of decisive importance for making a rational diagnosis and therapy considering the patient's well-being. Therefore, histological and clinical characteristics of important granulomatous diseases that typically manifest on the face are presented here.
