Abstract
A síndrome POEMS é uma rara doença de plasmócitos. A ocorrência de hipertensão pulmonar como complicação respiratória da síndrome é pouco frequente e pode estar ligada ao aumento de várias citocinas, quimiocinas e fatores de crescimento como parte dos fenômenos inflamatórios que cercam a fisiopatologia da síndrome POEMS. Descrevemos o caso de uma mulher de 54 anos com síndrome POEMS e hipertensão pulmonar, que foi tratada com corticoide como terapia de primeira linha. Tratava-se de uma paciente com clássicos sintomas dessa síndrome: polineuropatia (confirmada por eletroneuromiografia), organomegalia, hipotireoidismo subclínico, gamopatia monoclonal em dosagem urinária e alterações cutâneas. A cateterização cardíaca direita revelou pressão arterial pulmonar média de 48 mmHg, débito cardíaco de 4,1 L/min e resistência vascular pulmonar de 8,05 Woods. O nível sérico de brain natriuretic peptide (BNP) foi de 150 pg/mL. Nenhuma outra doença foi encontrada durante investigação. Prednisona (1 mg/kg por três meses) foi iniciada, com dramática melhora clínica e funcional, além de normalização dos níveis dos hormônios tireoidianos e de proteína em urina por eletroforese. A pressão arterial pulmonar média caiu para 26 mmHg, o débito cardíaco para 3,8 L/min e a resistência vascular pulmonar para 2,89 Woods. O nível sérico de BNP caiu para 8pg/mL. Nossos achados indicam o potencial papel da corticoterapia como primeira linha de tratamento na hipertensão pulmonar associada à síndrome POEMS. Diante da raridade dessa apresentação, um registro multicêntrico deveria ser desenvolvido para permitir a aquisição de mais dados que suportem essa conduta.
The POEMS syndrome is a rare plasma cell disease. Pulmonary hypertension is an infrequent respiratory complication of this syndrome and might be associated with increased levels of various cytokines, chemokines and growth factors as part of the inflammatory phenomena that involve the physiopathology of POEMS syndrome. We present the case of a 54-year-old woman diagnosed with POEMS syndrome and pulmonary hypertension, which were treated with corticosteroids as the first-line therapy. The patient presented with the classic symptoms of this syndrome: polyneuropathy (confirmed by electromyography), organomegaly, subclinical hypothyroidism and monoclonal gammopathy detected in urine, together with skin changes. Right heart catheterization revealed a mean pulmonary artery pressure of 48 mmHg, a cardiac output of 4.1 L/min and pulmonary vascular resistance of 8.05 Woods. The serum level of brain natriuretic peptide (BNP) was 150 pg/mL. No other underlying disease was found during the investigation. Prednisone (1 mg/kg for three months) was then initiated, with a dramatic improvement in the clinical and functional condition. Levels of thyroid hormones and urinary protein levels (as determined using electrophoresis) normalized. Mean pulmonary artery pressure decreased to 26 mmHg, cardiac output decreased to 3.8 L/min, and pulmonary vascular resistance decreased to 2.89 Woods. Serum levels of BNP dropped to 8 pg/mL. Our findings suggest that corticosteroids could play a role as a first-line treatment in pulmonary hypertension accompanied by POEMS syndrome. Due to the rarity of this presentation, a multicenter registry should be developed to allow the compilation of additional data to support this practice.
