RESUMEN
Objetivos: Evaluar aspectos del metabolismo óseo basal en pacientes con cáncer de próstata y el efecto, en práctica clínica habitual, de diferentes esquemas de tratamiento (intermitente o continuo) con agonistas de la hormona liberadora de hormona luteinizante (LH-RH) y del denosumab en la evolución de la densidad mineral ósea (DMO).MétodosEstudio observacional retrospectivo de una cohorte de pacientes con cáncer de próstata en tratamiento con agonistas LH-RH, valorados en el servicio de reumatología de un hospital de tercer nivel. Se recogieron datos demográficos, índice de FRAX, esquema de tratamiento LH-RH, tratamiento de osteoporosis, datos de laboratorio y de DMO. Se usaron modelos de regresión lineal de efecto mixto analizando la interacción de los esquemas de tratamiento LH-RH, denosumab y la evolución de DMO.ResultadosSe incluyeron 83 pacientes (73±8años). Evaluación basal: el 16% de los pacientes presentaron osteoporosis densitométrica y además un 27% un riesgo elevado de fractura (FRAX). El 80% tenían niveles de vitaminaD <30ng/l. La pauta intermitente de agonistas LH-RH y los niveles elevados de vitaminaD se asociaron a mejor DMO basal. No se detectó asociación entre la evolución de la DMO y las pautas de tratamiento de agonistas LH-RH, pero sí se encontró una correlación positiva con denosumab.ConclusionesUna elevada proporción de pacientes presentaban un alto riesgo de fractura o niveles insuficientes de vitaminaD no detectados previamente. El estudio tanto del metabolismo óseo como del riesgo de fractura son convenientes en estos pacientes. En práctica clínica habitual el efecto sobre la DMO del denosumab se detecta a corto plazo, mientras que el del esquema intermitente con agonistas LH-RH es menos evidente. (AU)
Objectives: To evaluate the aspects of the basal bone health status in prostate cancer patients. Furthermore, to evaluate in a real-world setting the effect of different schemes (intermittent or continuous) of androgen deprivation therapy (ADT) and the effect of denosumab in bone mass density (BMD).MethodsObservational, retrospective study of a cohort of prostate cancer patients in treatment with luteinizing hormone-releasing hormone (LH-RH) agonists, evaluated in the rheumatology department of a tertiary center. Demographics, FRAX score, LH-RH treatment scheme, osteoporosis treatment, laboratory data and BMD were collected. Mixed effect regression models to analyze the interaction between LH-RH treatment scheme, denosumab and BMD evolution were used.ResultsEighty-three patients (mean age 71±8years) were included. At the basal evaluation, 16% of patients presented densitometric osteoporosis and 27% of patients presented high fracture risk. Eighty percent of patients had inadequate vitaminD levels. VitaminD >30ng/mL was correlated with higher T-scores. There was no association between LH-RH treatment scheme and BMD evolution, however there was a positive association with denosumab.ConclusionA high proportion of patients presented elevated fracture risk or inadequate vitaminD levels, not previously recognized. Bone health assessment and fracture risk evaluation are convenient in these patients. In a real-world setting, the effect of denosumab in BMD is detected, however the effect of intermittent LH-RH schema treatment is less evident. (AU)

OBJETIVO: La polimialgia reumática (PMR) puede asociarse a vasculitis de grandes vasos (VGV). Este trabajo pretende evaluar el papel de 18F-FDG PET/TC en el diagnóstico de VGV asociado a PMR. MATERIALES Y MÉTODO: Estudio retrospectivo de pacientes con PMR. Se recogieron datos clínicos, analíticos, reactantes de fase aguda (RFA) (PCR, VSG), y a quienes tenían clínica persistente, elevación de RFA, precisaban dosis elevadas de corticoterapia o cuadros atípicos de PMR (febrícula, pérdida de peso, etc.) se realizó 18F-FDG PET/TC. RESULTADOS: Veintitrés pacientes se incluyeron; el 48% (11) de los cuales tuvieron VGV asociada a PMR. La localización fue heterogénea pero en su mayoría involucró a la aorta. En cuanto al tratamiento, se añadieron fármacos modificadores de la enfermedad a más del 80% de los pacientes con VGV. Los pacientes con VGV tenían niveles de PCR elevados comparado con aquellos con PMR aislada. CONCLUSIONES: La VGV en PMR no es infrecuente, tanto la clínica como los valores de PCR elevados deben hacer sospechar la posibilidad de VGV asociada. El estudio de imagen 18F-FDG PET/TC es una herramienta útil identificando VGV asociada a PMR
OBJECTIVE: Polymyalgia rheumatica (PR) can be associated with large vessel vasculitis (LVV). We evaluate the diagnostic role of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) and its impact on the treatment of LVV associated with PR. MATERIALS AND METHODS: Retrospective study of patients diagnosed with PR. Data was collected from health records. Blood analysis included acute-phase reactants (APR), C-reactive protein (CRP) and erythrocyte sedimentation rate. An 18F-FDG PET/CT scan was performed in those patients whose symptoms persisted, in those with elevated APR, those who required higher doses of steroids or those who had atypical features of PR (low-grade fever, weight loss, among others). RESULTS: Twenty-three were eligible; 48% (n = 11) of the patients were diagnosed with LVV associated with PR. The site was heterogeneous, but mostly involved the aorta. In 80% of the patients with LVV, a disease-modifying antirheumatic drug was added to their treatment. Elevated CRP values were associated with the likelihood of presenting LVV. CONCLUSIONS: LVV is not uncommon, clinical features and elevated CRP levels should raise suspicion of LVV associated with PR. 18F-FDG PET/CT is useful in identifying LVV associated with PR
