- The road to biologics in patients with hidradenitis suppurativa: a nationwide drug utilization study. [Journal Article]
- CONCLUSIONS: Patients with HS who receive biologic therapy have long preceding treatment histories with multiple drug classes and treatment series, many of which are supported by relatively weak evidence in HS. Delay in the initiation of biologic therapy may represent a missed opportunity to prevent disease progression. What is already known about this topic? The treatment journey leading to biologic therapy in patients with HS has not previously been investigated. What does this study add? Our data from 225 patients with HS illustrate that patients who receive biologic therapy have long preceding treatment histories with multiple drug classes and treatment series, many of which are supported by relatively weak evidence in HS.

- Therapeutic Options for the Treatment of Darier's Disease: A Comprehensive Review of the Literature. [Review]
- Darier's disease (also known as keratosis follicularis or dyskeratosis follicularis) is an autosomal dominant inherited disorder which manifests as hyperkeratotic greasy papules in the first or second decade of life. Aside from symptom management and behavioral modifications to avoid triggers, there are currently no validated treatments for Darier's disease (DD). However, a variety of treatments …

- Premature ventricular contractions associated with isotretinoin use. [Case Reports]
- Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions.

- Inflammatory bowel disease (IBD) may develop due to an inflammatory response to commensal gut microbiota triggered by environmental factors in a genetically susceptible host. Isotretinoin (acne therapy) has been inconsistently associated with IBD onset and flares but prior treatment with antibiotics, also associated with IBD development, complicates the confirmation of this association. Here we s…

- Isotretinoin: controversies, facts, and recommendations. [Review]
- Since it was introduced to the market by Hoffman-La Roche (Roche) in 1982, isotretinoin has remained the most effective treatment for severe and recalcitrant acne. However, it has also been surrounded by controversy due to its teratogenicity and inconsistent associations with depression, suicidality, inflammatory bowel disease, increases in lipid levels, and elevated transaminases. Areas covered:…

- Large-scale survey to describe acne management in Brazilian clinical practice. [Journal Article]
- CONCLUSIONS: This survey illustrates that Brazilian dermatologists employ complex treatment regimens to manage acne, choosing systemic drugs, particularly isotretinoin, even in some cases of grade I acne, and heavily prescribe antibiotics. Because complex regimens are harder for patients to comply with, this result notably raises the question of adherence, which is a key factor in successful treatment.

- Based on the Food and Drug Administration Adverse Event Reporting System (FAERS), the FDA and Hoffman La Roche issued warnings of a possible causal association between isotretinoin and inflammatory bowel disease. While scientists studied the association, trial lawyers used the courts to award large sums of money to plaintiffs despite the absence of clear scientific evidence of a causal effect. In…

- With Roche's withdrawl of Accutane from the U.S. market in 2009, isotretinoin has only been available in its generic form. Many clinicians fail to realize that for approval by the U.S. Food and Drug Administration, a generic medication must have a bioequivalence between 80 percent and 125 percent of that of the innovator product. This potential variability in bioavailability between branded and g…

- [Isotretinoin: compliance with recommendations in childbearing women]. [Journal Article]
- CONCLUSIONS: Despite 3 successive isotretinoin prescription and issue recommendations strengthening in childbearing women, pregnancies can't be totally avoided. Bad compliance concerns the prescription and/or an incomplete or not understood information by the patient who does not scrupulously apply the care and contraception agreement. However, this study does not allow to assess the proportion of issued prescriptions despite their non-accordance with the licence criteria. The National Commission of Pharmacovigilance did not like to limit isotretinoin prescription to dermatologists only. It estimates that the administrative authority must intensify information by dermatologists, general practitioners and pharmacists, about measures to take to avoid an exposure to isotretinoin during pregnancy.
- Trends in adherence to a revised risk management program designed to decrease or eliminate isotretinoin-exposed pregnancies: evaluation of the accutane SMART program. [Journal Article]

The presence of a qualification sticker may not have an impact on pregnancy testing or compliance with effective birth control behavior as outlined in the SMART program.
