    Abstract Pseudo-Cushing syndromes are a heterogeneous group of disorders, including alcoholism, anorexia nervosa, visceral obesity, and depression, which share many of the clinical and biochemical features of Cushing's syndrome. The mechanisms responsible for the genesis of pseudo-Cushing's syndrome are poorly understood. It has been suggested that hypercortisolism of pseudo-Cushing syndrome may be the result of increased hypothalamic corticotrophin-releasing hormone (CRH) secretion in the context of a hypothalamic-pituitary-adrenal axis that is otherwise normally constituted. The substantial overlap in clinical and biochemical features among several patients with Cushing syndrome and those with pseudo-Cushing syndromes can make the differential diagnosis difficult. Distinguishing between pseudo-Cushing's syndrome and true Cushing's syndrome is critical for preventing the unnecessary and potentially harmful treatment of such patients. This brief review summarizes the main pathophysiological events of pseudo-Cushing syndromes and provides a useful strategy for differential diagnosis.

    Title translation Exogenous Cushing's syndrome and glucocorticoid withdrawal.
    Abstract Glucocorticoids are widely used in clinical practice to control the activity of autoimmune, inflammatory, allergic diseases and other nosological entities. Therapeutic doses of glucocorticoids are often administered inappropriately and it is a particular problem because chronic therapy has many side effects, ranging from suppression of the hypothalamic-pituitary-adrenal axis and Cushing's syndrome to infections and changes in mental status. Factors influencing both the therapeutic and adverse effects of glucocorticoids include the pharmacokinetic properties of the glucocorticoid, daily dosage, individual differences in steroid metabolism and the duration of treatment. When used to control the activity of these diseases, four aspects of glucocorticoid withdrawal deserve special attention. First, the illness treated by steroids may relapse. Second, the hypothalamic-pituitary-adrenal axis may remain suppressed for a long time. Third, psychological dependence to these hormones often develops. Fourth, a nonspecific withdrawal syndrome may develop even while patients are receiving physiological replacement doses of glucocorticoids. The severity of the withdrawal syndrome depends on the phase and degree of dependence and includes many symptoms as anorexia, nausea, emesis, weight loss, fatigue, myalgias, arthralgias, headache, abdominal pain, lethargy, postural hypotension, fever, and skin desquamation.

    Abstract Síndromes de pseudo-Cushing são um grupo heterogêneo de doenças, incluindo alcoolismo, anorexia nervosa, obesidade visceral e depressão, que compartilham muitas das características clínicas e bioquímicas da síndrome de Cushing. Os mecanismos responsáveis para a gênese da síndrome de pseudo-Cushing são fracamente compreendidos. Tem sido sugerido que o hipercortisolismo da síndrome de pseudo-Cushing pode ser resultante do aumento da secreção do hormônio liberador de corticotrofina (CRH) hipotalâmico no contexto de um eixo hipotálamo-hipofisário-adrenal que, de outra maneira, está normalmente constituído. A sobreposição substancial entre as características clínicas e laboratoriais entre muitos pacientes com síndrome de Cushing e aqueles com síndrome de pseudo-Cushing pode tornar o diagnóstico diferencial difícil. Distinguir entre síndrome de pseudo-Cushing e síndrome de Cushing verdadeira é crítico para se prevenir o tratamento desnecessário e potencialmente prejudicial de tais pacientes. Esta breve revisão sumariza os principais eventos patofisiológicos das síndromes de pseudo-Cushing e fornece uma estratégia útil para o seu diagnóstico diferencial.

    Abstract Glicocorticóides são amplamente utilizados na prática clínica para o controle da atividade de doenças auto-imunes, inflamatórias, alérgicas e outras entidades nosológicas. Doses terapêuticas de glicocorticóides são muita vezes administradas inapropriadamente e isto é um problema particular, pois a terapia crônica tem muitos efeitos colaterais que se estendem desde a supressão do eixo hipotálamo-hipofisário-adrenal e síndrome de Cushing até infecções e alterações do status mental. Fatores que influenciam tanto nos efeitos adversos quanto nos terapêuticos dos glicocorticóides incluem propriedades farmacocinéticas do glicocorticóide, dose diária, diferenças individuais no metabolismo esteróide e duração do tratamento. Quando utilizados para o controle da atividade destas doenças, quatro aspectos da retirada de glicocorticóide merecem atenção especial. Primeiro, a doença tratada pelo esteróide pode recorrer. Segundo, o eixo hipotálamo- hipófise-adrenal pode permanecer suprimido por um longo período. Terceiro, muitas vezes desenvolve-se dependência psicológica a esses hormônios. Quarto, uma síndrome de retirada inespecífica pode desenvolver mesmo enquanto os pacientes estão recebendo doses de reposição fisiológica de glicocorticóides. A gravidade da síndrome de retirada depende da fase e o grau de dependência e inclui sintomas tais como anorexia, náusea, vômitos, perda de peso, fadiga, mialgias, artralgias, cefaléia, dor abdominal, letargia, hipotensão postural, febre e descamação da pele.
