Osteonecrosis múltiple inducida por glucocorticoides / Multiple osteonecrosis induced bye glucocorticoids / Osteonecrose múltipla induzida por glicocorticóides

La osteonecrosis múltiple es una entidad poco frecuente que se define por el compromiso de al menos tres regiones diferentes. Es indispensable el abordaje multidisciplinario de los pacientes que la padecen tanto para el diagnóstico como el tratamiento oportuno. Presentamos el caso clínico de un paciente joven que presenta una osteonecrosis múltiple con compromiso de ambas caderas, hombros, rodillas, codo derecho y cuello de pie izquierdo. El principal factor de riesgo presente en nuestro caso es el consumo de glucocorticoides.

Multiple osteonecrosis is a rare entity that is defined by the involvement of at least three different regions. A multidisciplinary approach to patients who suffer from it is essential for both diagnosis and timely treatment. We present the clinical case of a young patient who presented multiple osteonecrosis with involvement of both hips, shoulders, knees, right elbow, and neck of the left foot. The main risk factor present in our case is the consumption of glucocorticoids.

A osteonecrose múltipla é uma entidade rara que se define pelo envolvimento de pelo menos três regiões diferentes. Uma abordagem multidisciplinar aos pacientes que sofrem com isso é essencial para o diagnóstico e tratamento oportuno. Apresentamos o caso clínico de um paciente jovem que apresenta osteonecrose múltipla envolvendo quadris, ombros, joelhos, cotovelo direito e pescoço do pé esquerdo.

Síndrome de Cushing exógeno por interacción medicamentosa de ritonavir y fluticasona inhalada. Reporte de tres casos pediátricos / Exogenous Cushing syndrome due to drug interaction of ritonavir and inhaled fluticasone. Report of three pediatric cases

El incremento de la expectativa de vida con el advenimiento de la terapia antirretroviral de alta eficacia plantea desafíos en cuanto a la toxicidad e interacciones medicamentosas. El síndrome de Cushing exógeno por interacción entre ritonavir y fluticasona inhalada en niños con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica es infrecuente. Hasta el momento, hay 20 casos reportados. Se describen 3 casos pediátricos con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica que presentaron síndrome de Cushing exógeno con fluticasona inhalada en dosis habituales por la interacción medicamentosa entre esta y ritonavir. Los pacientes resolvieron el cuadro clínico luego de 2-4 meses de suspensión de la fluticasona y permanecieron asintomáticos en el seguimiento

The increase in life expectancy with the advent of highly effective antiretroviral therapy poses challenges in terms of toxicity and drug interactions. Exogenous Cushing syndrome by interaction between ritonavir and inhaled fluticasone in children diagnosed with human immunodeficiency virus infection and chronic pulmonary pathology is rare. So far, there are 20 cases reported. Three pediatric cases are reported, with a diagnosis of human immunodeficiency virus infection and chronic pulmonary pathology who presented exogenous Cushing syndrome with inhaled fluticasone at usual doses due to drug interaction between it and ritonavir. The patients resolved the clinical Síndrome de Cushing exógeno por interacción medicamentosa de ritonavir y fluticasona inhalada. Reporte de tres casos pediátricos Exogenous Cushing syndrome due to drug interaction of ritonavir and inhaled fluticasone. Report of three pediatric cases picture after 2-4 months of fluticasone suspension and remain asymptomatic in the follow-up.

Síndrome de Cushing iatrogénico por corticoides inhalados en paciente VIH / Cushing syndrome in a HIV patient using inhaled steroids: report of one case

We report a 41-year-old man with HIV and a chronic obstructive pulmonary disease, treated for seven months with Fluticasone/Salmeterol and antiretroviral therapy (Lamivudine, Tenofovir, Atazanavir and Ritonavir). While using these medications, the patients developed a Cushing syndrome in a period of five months. After performing laboratory and imaging tests, it was concluded that the most probable cause of the syndrome was the interaction of inhaled steroids with Ritonavir. After discontinuing these medications the syndrome reverted in a period of 8 months.
