Lacrimal gland atrophy and dry eye related to isotretinoin, androgen, and prolactin: differential diagnosis for Sjögren's syndrome / Atrofia das glândulas lacrimais e olho seco relacionados aisotretinoína, androgênio e prolactina: diagnóstico diferencial com a síndrome de Sjögren

ABSTRACT This report is of three cases of sicca syndrome, initially suspected to be Sjögren's syndrome, which was ruled out by clinical and laboratory investigations. The patients were a 24-year-old woman, a 32-year-old man, and a 77-year-old woman with chronic symptoms of sicca syndrome, including dry eye syndrome. The first case was associated with the use of isotretinoin, a retinoic acid. The second was associated with the use of anabolic androgenic steroids, and the third was related to a prolactin- secreting pituitary adenoma. All cases manifested sicca, including dry eye syndrome, after those events, and the manifestations persisted. Magnetic resonance imaging revealed bilateral atrophy of the lacrimal gland. The medical history, ocular examinations, laboratory exams, and magnetic resonance images confirmed dry eye syndrome; however, the exams were all negative for Sjögren's syndrome. The lacrimal gland was absent on magnetic resonance imaging in all three cases. The clinical history revealed that the signs and symptoms appeared after chronic exposure to retinoic acid, anabolic androgenic steroids, and a prolactin-secreting pituitary adenoma, respectively. Chronic isotretinoin, anabolic androgenic steroids, and prolactin-secreting pituitary adenoma or, in this last case, its inhibitory treatment, can cause lacrimal gland atrophy, sicca syndrome, and dry eye syndrome, and a differential diagnosis of Sjögren's syndrome. Further studies on doses, time, and other susceptibilities to the long-lasting adverse effects of retinoic acid, anabolic androgenic steroids, and the repercussions of prolactin-secreting pituitary adenoma are necessary to confirm and expand upon these associations.

RESUMO O relato descreve três casos de síndrome de sicca, inicialmente suspeitos de serem a síndrome de Sjögren, que fo­ram negados pela investigação clínica e laboratorial. O primeiro associado ao uso de isotretinoína, um ácido retinóico, o segundo ao uso de esteroides androgênicos anabolizantes e o terceiro relacionado ao adenoma da hipófise secretora da prolactina, todos manifestaram sicca, incluindo a síndrome do olho seco após esses eventos e as manifestações persistem. A ressonância magnética revelou atrofia bilateral da glândula lacrimal. Eles eram uma mulher de 24 anos, um homem de 32 anos e uma mulher de 77 anos com sintomas crônicos da síndrome de sicca, incluindo a síndrome do olho seco. A história médica, o exame ocular, os exames laboratoriais e a ressonância magnética foram confirmados como síndrome do olho seco, no entanto, todos os exames foram negativos para a síndrome de Sjögren. A glândula lacrimal estava ausente na ressonância magnética nos três casos. A história clínica revelou que sinais e sintomas se manifestaram após exposição crônica ao ácido retinóico, esteróides anabolizantes androgênicos e adenoma secretivo da prolactina hipofisária, respectivamente. Isotretinoína crônica, esteroides anabólicos androgênicos e adenoma hipofisário secretor de prolactina ou, neste último caso, seu tratamento inibitório pode ser a causa da atrofia da glândula lacrimal, síndrome da sicca e síndrome do olho seco e diagnóstico diferencial da síndrome de Sjögren. Estudos adicionais sobre doses, duração e outras suscetibilidades aos efeitos adversos duradouros do ácido retinóico, esteroides androgênicos anabólicos e repercussões do adenoma da hipófise secretora da prolactina são necessários para confirmar e detalhar essas associações.

Effects of oral isotretinoin therapy on the nasal cavities / Efeitos nasais da terapia com isotretinoína oral

Abstract Introduction Isotretinoin (13 cis-retinoic acid) is the most effective treatment for acne vulgaris and is the only treatment option that can provide either remission or a permanent cure. Objective The aim of this study was to use both subjective and objective methods to assess the nasal complaints of patients with severe acne who received oral isotretinoin therapy. Methods Fifty-four subjects were enrolled in the study. All the subjects were assessed with subjective (NOSE and VAS questionnaires) and objective (rhinomanometry and saccharine) tests to determine the severity of their nasal complaints. Results The mean severity scores (min: 0; max: 100) for nasal dryness/crusting and epistaxis were 0.47 ± 1.48 (0-5); 0.35 ± 1.30 (0-5) at admission, 3.57 ± 4.45 (0-10); 2.26 ± 4.71 (0-20) at the first month, and 4.28 ± 6 (0-20); 2.26 ± 4.71 (0-20) at the third month of the treatment respectively. Total nasal resistance of 0.195 ± 0.079 (0.12-0.56) Pa/cm3/s at admission, 0.21 ± 0.084 (0.12-0.54) Pa/cm3/s at the first month, and 0.216 ± 0.081 (0.14-0.54) Pa/cm3/s at the third month. Conclusion Oral isotretinoin therapy can cause the complaint of nasal obstruction. In addition, nasal complaints, such as dryness/crusting and epistaxis, significantly increase in patients during the therapy schedule.

Embriopatía por isotretinoína: Una entidad que puede evitarse / Isotretinoin embryopathy: An entity that can be avoided

La isotretinoína es el medicamento más efectivo en el tratamiento del acné noduloquístico recalcitrante grave. Sin embargo, el tratamiento con este fármaco se encuentra asociado con efectos adversos, y el más grave es la teratogénesis. Se ha estimado que 40% de los embarazos expuestos a isotretinoína presenta un aborto espontáneo y 35% desarrolla embriopatía. Se presenta el caso de un recién nacido con antecedente de exposición prenatal a isotretinoína, una entidad clínica que puede evitarse, con graves defectos congénitos en el sistema nervioso central e importantes dismorfias faciales, con evolución clínica desfavorable.

Isotretinoin is the most effective drug in the treatment of severe recalcitrant nodulocystic acne. However, treatment with this drug is associated with adverse effects, the most severe being teratogenesis. It has been estimated that 40% of pregnancies exposed to isotretinoin present spontaneous abortion and 35% develop embryopathy. We present the case of a newborn with a history of prenatal exposure to isotretinoin, a clinical entity that can be avoided, with severe congenital defects in the central nervous system and important facial dysmorphisms, with unfavorable clinical course.

Premature ventricular contractions associated with isotretinoin use

Abstract Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions. This report describes a 33-year-old-woman who presented with palpitations for 1 week while undergoing 1-month isotretinoin treatment for mild-moderate facial acne. An electrocardiogram and Holter monitoring showed premature ventricular contractions during isotretinoin (Roaccutane, Roche) treatment. Isotretinoin-related premature ventricular contractions were strongly suggested in this case due to the existence of documented premature ventricular contractions on electrocardiograms and the disappearance of these premature ventricular contractions two weeks after termination of the treatment To the authors' knowledge, there has been 1 reported case of premature ventricular contractions linked to isotretinoin use; this report describes a second such case.

Paronychia and granulation tissue formation during treatment with isotretinoin

Abstract This paper describes the association of two unusual side effects of treatment with isotretinoin for severe acne: paronychia and excess granulation tissue in the nails furrows. We report a case of male patient aged 19 years, who in the course of the 36th week of treatment with isotretinoin for acne grade III showed erythema, edema, excess granulation tissue and onychocryptosis in various nail beds of hands and feet, with no history of trauma associated. A literature review revealed few reports of these adverse events, and two clinical patterns of exuberant granulation tissue has been described: one in periungual location and other in lesions of previous acne. The rarity and lack of knowledge on the best treatment for granuloma-like reactions make this theme a considerable challenge.

Hepatitis autoinmune inducida por isotretionina / Autoimmune hepatitis induced by isotretionine

Se describe el caso de una paciente adolescente con el diagnóstico de hepatitis autoinmune asociada a isotretionina. Es una paciente de sexo femenino de 16 años, con antecedente de enfermedad de Hashimoto controlada con levotiroxina, que inicia tratamiento con isotretionina (Accutane) a una dosis de 20 mg c/ 12 horas por 3 meses para el tratamiento de acné severo. Al examen físico no se encuentran anormalidades y los exámenes de laboratorio fueron los siguientes: Al inicio del tratamiento AST 28 y ALT 28 U/L, y luego de los 3 meses, llega al máximo de: AST 756 U/L, ALT 1199 U/L, fosfatasa alcalina 114 U/L y presentando valores normales de bilirrubinas a lo largo del cuadro clínico. El estudio de serología fue negativo para todas las hepatitis virales, encontrándose ANA positivo (1/160) y niveles elevados de IgG. Una biopsia hepática practicada fue compatible con el diagnostico de hepatitis autoinmune. Se procede a iniciar corticoterapia con Prednisona a una dosis de 40 mg diarios una semana después de detener el tratamiento con isotretionina, observándose una mejoría en los valores de laboratorio. Describimos este caso y hacemos una revisión de la literatura mundial debido a que no se ha descrito aun un caso de hepatitis autoinmune inducida por isotretinoina...

We describe a case of a teenage patient with the diagnosis of drug induced autoimmune hepatitis. The patient is a 16 years old female, with the past medical history of HashimotoÆs hypothyroidism controlled with levothyroxine, who started treatment with Isotretionin (Accutane) 20 mg q/12 hours for a total of 3 months for the treatment of severe acne. The physical examination was within normal limits and the results of the laboratory exams are: Baseline values of ALT 28 U/L, AST 28 U/L. Three months later: AST 756 U/L, ALT 1199U/L, alkaline phosphatase 114 U/L, with normal bilirrubin levels throughout the process. The serology studies were negative for all viral hepatitis; ANA titers were positive (1/160) and igG levels were also elevated. A liver biopsy was performed, and was compatible with the diagnosis of autoimmune hepatitis. Corticosteroid therapy was started with Prednisone 40 mg per day one week after stopping the treatment with isotretionin, observing an improvement in the laboratory values. We describe this case and review the world literature since there are no reported cases of Isotretinoininduced autoimmune hepatitis...

Pseudo-acne fulminans associated with oral isotretinoin

Acne fulminans is a rare and serious condition characterized by the sudden onset of nodular and ulcerative acne lesions associated with systemic symptoms. It has been recognized a subset of patients with a sudden worsening of acne, often during treatment with oral isotretinoin, but without the strong presence of systemic involvement. Recognized by some authors as "pseudo-acne fulminans" or " acne fulminans sine fulminans," we report a case with these features in order to draw attention to the recognition and early management of this manifestation.

Sacroiliitis after use of oral isotretinoin - association with acne fulminans or adverse effect? / Sacroileite apos uso de isotretinoina oral - associacao com acne fulminans ou efeito adverso?

Acne fulminans is a rare and severe form of acne that may evolve from acne vulgaris, especially in male adolescents, or occur as an adverse effect of oral isotretinoin. Arthritis is a serious clinical manifestation when the musculoskeletal system is compromised by AF and has been reported as a rare adverse effect of isotretinoin. Involvement of the sacroiliac joints occurs in 21% of acne fulminans cases. We present the case of a 18-year-old male patient in whom acne fulminans evolved from acne vulgaris grade IV and after inflammation resolution started treatment with oral isotretinoin. Within a 30-day period of retinoid treatment he presented with back pain followed by rapid, progressive inability to deambulate.

Acne fulminans é uma forma grave e rara de acne que pode ser evolução da acne vulgar, principalmente em adolescentes do sexo masculino, ou ser precipitada durante o tratamento com isotretinoína oral. A artrite pode ocorrer como grave complicação na acne fulminans e já foi relatada como efeito adverso raro da isotretinoína. O acometimento das articulações sacroilíacas ocorre em 21% das artrites associadas à acne fulminans. Relatase caso de paciente masculino, 18 anos, que desenvolveu acne fulminans a partir de acne vulgar grau IV/conglobata e após resolução do quadro inflamatório, foi iniciado tratamento da acne com isotretinoína. Com 30 dias de uso do retinóide, o paciente iniciou dor lombar com piora rápida, progressiva que o incapacitou de deambular.

The effect of isotretinoin on triglycerides and liver aminotransferases / Influência da isotretinoína nas transaminases hepáticas e triglicerídeos

BACKGROUND: Isotretinoin has been used to treat the most severe cases of acne; however, it may provoke adverse events in mucocutaneous and hepatic tissues, lead to alterations in lipid levels and cause teratogenicity. OBJECTIVE: The objective of this study was to evaluate the profile of changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST) and triglyceride levels in patients who had been treated with oral isotretinoin dispensed by the São Mateus/ES pharmacy for special drugs. METHODS: A retrospective, observational, longitudinal study was conducted by carrying out a secondary analysis of each patient's data. RESULTS: Of the 130 patients who received isotretinoin between January and December 2009, only 70 were actually treated for 3 months or more and handed in the results of their laboratory tests. Of these 70 patients, 39 (55.7%) were female. The mean age of the women (23.9 years) was higher than the mean age of the men (20.1 years). There was a statistically significant increase in the levels of triglycerides (87.01 ± 48.25 versus 105.32 ± 48.76 mg/dL), AST (20.44 ± 6.26 versus 24.38 ± 11.92 U/L) and ALT (18.24 ± 8.31 versus 23.34 ± 20.03 U/L) performed prior to and 3 months or more after oral isotretinoin treatment. After treatment with oral isotretinoin, triglyceride levels had increased beyond the normal range in 11% of the patients, while 8.6% had elevated AST levels and 7.3% had increased ALT levels. CONCLUSION: The results in this population show that the use of oral isotretinoin for the treatment of acne may result in altered triglyceride, AST and ALT levels. These findings are in accordance with data published previously in the scientific literature, confirming the need to monitor these patients.

FUNDAMENTOS: A isotretinoína tem sido usada no tratamento dos casos mais graves de acne, embora possa induzir reações adversas nos tecidos mucocutâneos e hepáticos, alterações nos níveis lipídicos e teratogenicidade. OBJETIVOS: Este estudo avaliou o perfil de alterações nas concentrações de Alanina Aminotransferrase, Aspartato Aminotransferrase e triglicerídeos em pacientes que fizeram uso de isotretinoína oral fornecida pelo serviço Farmácia de Medicamentos Excepcionais de São Mateus/ES. MÉTODOS: Foi realizado estudo observacional longitudinal exploratório retrospectivo, utilizando coleta de dados secundários de cada paciente. RESULTADOS: Dos 130 pacientes que receberam isotretinoína no período de janeiro a dezembro de 2009, somente 70 realizaram o tratamento por 3 meses ou mais e apresentaram os resultados dos exames. Desses 70 pacientes, 39 (55,7%) eram do sexo feminino. A média de idade das mulheres (23,9 anos) foi maior do que a média de idade dos homens (20,1 anos). Houve aumento estatisticamente significante nas dosagens de triglicerídeos (87,01±48,25 versus 105,32 ± 48,76), Aspartato Aminotransferrase (20,44 ± 6,26 versus 24,38 ± 11,92) e Alanina Aminotransferrase (18,24 ± 8,31 versus 23,34 ± 20,03), realizadas antes e após 3 meses ou mais de tratamento com isotretinoína oral. Após o tratamento com isotretinoína oral, 11% dos pacientes apresentaram elevação de triglicerídeos acima dos valores normais, 8,6% apresentaram elevação da Aspartato Aminotransferrase e 7,3% tiveram elevação da Alanina Aminotransferrase. CONCLUSÃO: Os resultados mostraram que o uso de isotretinoína oral para o tratamento da acne, na população estudada, pode levar a alterações nas dosagens de triglicerídeos, Alanina Aminotransferrase e Aspartato Aminotransferrase, como mostrado pela literatura científica, confirmando a necessidade de monitoramento.

Embriopatía por isotretinoína con microtia-anotia y cardiopatía: Presentación de un caso / Isotretinoin embryopathy with microtia-anotia and congenital heart disease: Case report

La isotretinoína es un retinoide derivado de la vitamina A utilizado para el tratamiento del acné noduloquístico y refractario, pero ha sido catalogado como un medicamento teratogénico. Se ha comunicado un espectro de defectos congénitos que incluyen malformaciones craneofaciales, defectos cardíacos y defectos en el sistema nervioso con la exposición prenatal a este medicamento. Se presenta el caso de una recién nacida con antecedente de exposición prenatal a isotretinoína con defectos congénitos craneofaciales que incluyen parálisis facial, anotia derecha y microtia izquierda, y cardiopatía compleja.

Isotretinoin is a retinoid that derivates from vitamin A. It is indicated for recalcitrant nodular acne treatment, but it has been classifed as teratogenic. A wide spectrum of birth defects including craniofacial, heart and nervous system malformations have been described associated to prenatal exposure to this drug. We report the case of a newborn with a history of prenatal exposure to isotretinoin with craniofacial defects, including facial paralysis, right anotia, left microtia and complex heart disease.

Acne fulminans e isotretinoína: relato de caso / Acne fulminans and isotretinoin: case report

A acne fulminans é afecção rara e a forma mais grave de todo o espectro clínico da acne. Caracterizase pelo aparecimento súbito de nódulos inflamatórios dolorosos que ulceram, concomitantemente, a manifestações sistêmicas. Pode ser induzida pela isotretinoína e alguns autores acreditam que a ocorrência do quadro seja dose dependente. O tratamento é controverso, não havendo padronização até o momento. Apresenta-se caso desta rara doença, desenvolvida durante o uso de isotretinoína em baixas doses.

Acne fulminans (AF) is a rare disorder, the most severe form of the entire clinical spectrum of acne. It is characterized by emergence of painful inflammatory nodules that turn into ulcers, concomitant with systemic manifestations. It can be induced by isotretinoin and some authors believe that the occurrence of this condition is dose dependent. The treatment is controversial and there is no consensus up to this time. A case of this rare disease, developed during use of isotretinoin in low doses, is presented.

Mulheres adultas com acne apresentam maior risco de elevação de triglicerídeos ao uso de isotretinoína oral / Adult women with acne have a higher risk of elevated triglyceride levels with the use of oral isotretinoin

A isotretinoína apresenta restrições relacionadas a efeitos no perfil lipídico. Revisaram-se 90 pacientes tratados, em busca de fatores predisponentes a essas alterações. Houve elevação significativa do colesterol e triglicerídeos. Os pacientes em que estes últimos mostraram essa alteração foram, em sua maioria, do sexo feminino, predileção que não ocorria com as alterações iniciais. Mulheres com acne persistente talvez representem população de risco para tais efeitos colaterais.

There are restrictions associated with the use of isotretinoin because of its effects on the lipid profile. The records of ninety patients treated with this medication were reviewed to identify factors that would predispose patients to these abnormalities. A significant increase in cholesterol and triglyceride levels occurred. Patients in whom triglyceride levels increased were more likely to be female, although this difference was not present at baseline. Women with persistent acne may constitute a risk population for these side effects.

Acne fulminans incapacitante / Disabling Acne Fulminans

Acne fulminans é uma manifestação rara, que pode ocorrer durante a evolução da acne vulgar, principalmente, em adolescentes masculinos. Uso de isotretinoína, testosterona, e reações imunológicas exacerbadas no organismo são desencadeantes relacionados. Sinais, sintomas e alterações laboratoriais como: febre, hepatomegalia, poliartralgia, leucocitose, plaquetose, aumento de provas inflamatórias e transaminases, são característicos. A cintilografia óssea pode detectar lesões líticas em vários sítios do esqueleto. O tratamento é realizado com prednisolona, isotretinoína e antibióticos se infecções secundárias. Este caso relata um paciente masculino com diagnóstico de acne grau III, que desenvolveu acne fulminans e sacroileíte bilateral, com incapacidade de deambulação após início de terapia com isotretinoína.

Acne fulminans is a rare manifestation that may occur during the evolution of acne vulgaris primarily in male adolescents. Use of isotretinoin, testosterone, and exacerbated immune responses in the body are related triggers. Signs, symptoms and laboratory findings such as fever, hepatomegaly, polyarthralgia, leukocytosis, plaquetose, increased inflammatory markers and transaminases, are characteristic. A bone scan can detect osteolytic lesions in multiple skeletal sites. The treatment is performed with prednisolone, isotretinoin and antibiotics if secondary infection is present. This case describes a male patient with a diagnosis of grade III acne, who developed acne fulminans and bilateral sacroiliitis with inability to ambulate, after initiation of therapy with isotretinoin.
