HONOLULU, Hawaii — Within the scientific expertise of John S. Barbieri, MD, MBA, cheilitis happens in practically all sufferers taking any dose of isotretinoin.
“If they do not have dry lips, you must marvel in the event that they’re even absorbing isotretinoin,” Barbieri, director of the Superior Pimples Therapeutics Clinic at Brigham and Girls’s Hospital, Boston, mentioned on the Hawaii Dermatology Seminar supplied by MedscapeLIVE! “Everybody goes to get dry lips.”

Based on a retrospective evaluate of 1743 sufferers began on isotretinoin, different widespread mucocutaneous unwanted effects embody eczema, nostril bleeds, and eye issues. Rising analysis means that there could also be a task for oral omega-3 in reducing such unwanted effects of the drug. In a case control study, 118 sufferers had been randomized to isotretinoin alone or isotretinoin plus 1 g/day of oral omega-3 for 16 weeks. At week 16, the speed of dry lips was 26% within the isotretinoin solely group in contrast with 14% within the mixture group; related traits had been seen with dry nostril (11% vs 0%, respectively) and dry pores and skin (11% vs 2%).
“Omega-3 is a straightforward factor that we are able to take into consideration recommending for sufferers,” Barbieri mentioned. “It’s totally protected, cheap, and it could assist us handle these widespread sides impact we run into.”
One other potential aspect impact of isotretinoin that he characterised as underappreciated is persistent dry eye and different ocular adjustments. One retrospective cohort study of 14,682 adolescents and younger adults in Israel discovered that use of the drug resulted in decreased tear manufacturing and decreased tear high quality. In one other examine, a review and meta-analysis of 21 publications involving 1105 eyes of 842 sufferers, isotretinoin use was related to elevated conjunctival fluorescein staining, decreased corneal thickness, and worse patient-reported ocular floor illness index scores.
“These adjustments could also be mediated by meibomian gland dysfunction and atrophy,” Barbieri mentioned. “Fortuitously, many of those tear movie adjustments seem to resolve after therapy. These adjustments in corneal thickness do appear to get higher. That is reassuring.”
In a study of 54 patients handled with isotretinoin, tear manufacturing and high quality returned to baseline inside 6 months of therapy completion. “However some adjustments within the meibomian gland could also be persistent,” Barbieri mentioned. “At 6 and 12 months after the tip of therapy, you may nonetheless see changes within the meibomian glands of sufferers who had been handled with a regular course of 120 to 150 mg/kg isotretinoin,” he mentioned, referring to the outcomes of a examine of 88 sufferers.
One study investigated the results of omega-3 fatty acids and punctal plugs on tear movie and ocular floor parameters in 90 sufferers receiving systemic isotretinoin remedy. They had been divided into three teams: Those that acquired a smooth preloaded silicone plug that was inserted within the inferior punctum of each eyes and acquired oral omega-3 fatty acid capsules twice day by day for a complete dose of 1040 mg/day for six months; those that acquired a smooth preloaded silicone plug and oral placebo, and people who acquired isotretinoin alone. At 6 months’ follow-up, those that had been handled with omega-3 mixed with the preloaded silicone plug had higher meibomian gland perform than did those that acquired isotretinoin alone or isotretinoin with the preloaded silicone plug.
Barbieri additionally famous that antihistamines might play a task in enhancing the impact of isotretinoin. In one study, 20 sufferers had been handled with isotretinoin 0.4 mg/kg per day and 20 sufferers had been additionally handled with an antihistamine, desloratadine 5 mg/day for 12 weeks. At week 12, sufferers within the group handled with isotretinoin and the antihistamine confirmed a extra statistically vital lower in acne lesion counts, in contrast with the isotretinoin-only group (reductions of 44.8% vs 17.8%, respectively, in noninflammatory lesions; 55.8% vs 22.9% in inflammatory lesions, and 45.6% vs 18.7% in complete lesions (P < .05 for all associations).
A subsequent larger study yielded related findings. There have been additionally decrease charges of preliminary flaring and better charges of affected person satisfaction within the antihistamine teams in each research.
In an interview on the assembly, Lawrence F. Eichenfield, MD, chief of pediatric and adolescent dermatology at Rady Youngsters’s Hospital, San Diego, described Barbieri as “a pacesetter in taking a complete view on what the historical past and newest data is on isotretinoin. His contemporary strategy is one thing everybody ought to contemplate and determine what they will use of their observe.”
Barbieri disclosed that he receives consulting charges from Dexcel for work unrelated to his presentation. Eichenfield disclosed that he has been an investigator and/or guide for Almirall, Cassiopea, Dermata, Galderma, and Ortho Dermatologics.
