La arteritis de la temporal (AT) es la forma más frecuente de vasculitis sistémica, su diagnóstico está basado en criterios propuestos por el Colegio Americano de Reumatología (1990), y su tratamiento son corticoides a dosis elevadas. Nuestro objetivo es valorar el gasto del diagnóstico de la AT, y secundariamente análisis coste/efectivo de distintas estrategias diagnósticas (clínica, biopsia, eco-Doppler) y terapéuticas (suspensión del corticoide). Material y método: Estudio observacional, retrospectivo de pacientes con AT (2012-2021). Se recogieron datos demográficos, comorbilidades, signos y síntomas sugestivos de AT. Se diagnosticó AT con una puntuación ≥ 3 según los criterios del American College of Reumatology (ACR-SCORE). Se analizaron los gastos del diagnóstico y modificación de tratamiento. Resultados: Setenta y cinco pacientes, mediana edad 77 (6-87) a˜ nos. Cefalea, dolor temporal y claudicación mandibular fueron significativos para el diagnóstico de AT. Los pacientes con halo en eco-Doppler y biopsia positiva, presentaron elevación de VSG y PCR de forma significativa en comparación con los pacientes que no. El gasto diagnóstico de AT fue de 414,7 D /paciente. Si empleamos ACR-SCORE ≥ 3-eco-Doppler serían 167,2 D /paciente (ahorro del 59,6%) y ACR-SCORE ≥ 3-biopsia 339,75 D /paciente (ahorro del 18%). Si se retiraba corticoide y se realizaba biopsia hubiesen sido 21,6 D /paciente (ahorro del 94,7%), si se retiraba corticoide y se realizaba eco-Doppler hubiesen sido 10,6 D /paciente (ahorro del 97,4%). Conclusiones: Cefalea, dolor temporal y claudicación mandibular son predictores de AT. La elevación de VSG y PCR son predictores de biopsia positiva y presencia de halo en la ecografía. El empleo de ACR-SCORE ≥ 3 con eco-Doppler o con biopsia, y con suspensión del corticoide son coste/efectivos.
Temporal arteritis (TA) is the most common form of systemic vasculitis. Its diagnosis is based on criteria proposed by the American College of Rheumatology (1990), and its treatment is high-dose corticosteroids. Our objective is to assess the cost of diagnosing TA, and secondarily, cost-effective analysis of different diagnostic strategies (clinical, biopsy, Doppler ultrasound) and therapeutic strategies (corticosteroid suspension). Material and method: Observational, retrospective study has been carried out on patients with TA (2012–2021). Demographic data, comorbidities, signs and symptoms suggestive of TA were collected. TA was diagnosed with a score ≥3 according to American College of Rheumatoloy criteria (ACR-SCORE). The costs of diagnosis and treatment modification were analysed.
Results: Seventy-five patients have been included, median age 77 (46-87) years. Headache, temporal pain and jaw claudication were significant for the diagnosis of TA. Patients with a halo on Doppler ultrasound and a positive biopsy have significantly elevated ESR and CRP compared to patients who do not. The cost of the TA diagnosis was 414.7 euros/patient. If we use ACR-SCORE≥3-echodoppler it is 167.2 D /patient (savings 59.6%) and ACR-SCORE≥3-biopsy 339.75 D /patient (savings 18%). If the corticosteroid was removed and a biopsy was performed, 21.6 D /patient (94.7% savings), if the corticosteroid was removed and Doppler ultrasound was performed, 10.6 D /patient (97.4% savings). Conclusions: Headache, temporary pain and jaw claudication are predictors of TA. Elevated ESR and CRP are predictors of positive biopsy and presence of halo on ultrasound. The uses of ACR-SCORE≥3 with Doppler ultrasound or biopsy, and with corticosteroid suspension, are cost-effective.
