RESUMO

BACKGROUND: Isotretinoin is an efficacious treatment option for severe acne. Although isotretinoin often causes mild liver enzyme elevation, how acne patients should be monitored on isotretinoin therapy is not well characterized. OBJECTIVE: The purpose of this study was to assess the management and clinical outcome of acne patients with abnormal aspartate transaminase (AST) and alanine aminotransferase (ALT) when receiving isotretinoin. METHODS: A retrospective chart review was conducted in acne subjects with abnormal AST and ALT levels receiving isotretinoin. Abnormal liver enzymes were graded using the Common Terminology Criteria for Adverse Events version 5. RESULTS: Of 108 subjects with abnormal liver enzymes, 79 subjects were on isotretinoin 80 mg and 23 subjects were on isotretinoin 40 mg. Most abnormalities were during Month 1 of therapy (48). Of the 122 abnormal Grade 1 AST elevations, 40 normalized, 38 remained in Grade 1, and 1 increased into Grade 2 when a healthcare provider maintained the isotretinoin dose. Of the 102 abnormal Grade 1 ALT levels managed by maintaining the isotretinoin dose, 31 normalized and 38 remained persistently elevated. CONCLUSION: Most mild elevations of isotretinoin therapy do not worsen. Acne patients with isotretinoin may not need continued testing when experiencing low-grade liver enzyme abnormalities.

RESUMO

INTRODUCTION: Eosinophilic angiocentric fibrosis (EAF) is a rare lesion that predominantly affects the upper respiratory tract. Its etiology is unknown and it has been recently associated with the IgG4- related disease (IgG4-RD) spectrum. To the author's knowledge, this is the sixth case report of the relationship between EAF and IgG4-RD. CASE REPORT: We report the case of a 37-year-old woman with nasal deformity and facial pain. The lesion was surgically excised. Histological examination revealed features of EAF with an IgG4/IgG plasma cell ratio ≷73% and 31 IgG4 stained cells per high power field. No clinical or radiological recurrence was detected during follow-up. Serum IgG4 quantification one year after surgery was within normal limits. DISCUSSION: The relationship between both entities may have therapeutic impact because IgG4-RD of the head and neck has a high remission rate with corticosteroids and immunosuppressive therapy. Additional reports of this infrequent disease are necessary to elucidate appropriate treatment and prognosis.
