Cost-effectiveness analysis of the diagnosis of temporal arteritis.

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 AT (2012-2021). Demographic data, comorbidities, signs and symptoms suggestive of AT were collected. AT 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 AT diagnosis was 414.7 euros/patient. If we use ACR-SCORE ≥ 3-echodoppler it is 167.2 є/patient (savings 59.6%) and ACR-SCORE ≥ 3-biopsy 339.75 є/patient (savings 18%). If the corticosteroid was removed and a biopsy was performed, 21.6 є/patient (94.7% savings), if the corticosteroid was removed and Doppler ultrasound was performed, 10.6 є/patient (97.4% savings). CONCLUSIONS: Headache, temporary pain and jaw claudication are predictors of AT. 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.

Análisis coste/efectivo del diagnóstico de la arteritis de la temporal / Cost-effectiveness analysis of the diagnosis of temporal arteritis

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) años. 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€/paciente. Si empleamos ACR-SCORE≥3-eco-Doppler serían 167,2€/paciente (ahorro del 59,6%) y ACR-SCORE≥3-biopsia 339,75€/paciente (ahorro del 18%). Si se retiraba corticoide y se realizaba biopsia hubiesen sido 21,6€/paciente (ahorro del 94,7%), si se retiraba corticoide y se realizaba eco-Doppler hubiesen sido 10,6€/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.(AU)

Edema facial como manifestación inicial atípica de arteritis de células gigantes: a propósito de un caso y revisión de la literatura / Facial edema as an atypical initial manifestation of giant cell arteritis: a case report and review of the literature

Introducción: la arteritis de células gigantes es la vasculitis de vaso grande más frecuente y se ve predominantemente en adultos ma-yores de 50 años. El diagnóstico es en base a la clínica que se compone de cefalea, polimialgia reumática, sensibilidad en relación a la arteria temporal, compromiso del estado general, entre otras cosas, más laboratorio que se evidencia reactantes de fase aguda elevados y anemia y se confirma con biopsia de arteria temporal. Métodos: reporte de un caso de una paciente con debut con cefalea y aumento de volumen facial, lo que conllevó un diagnóstico erróneo de celulitis facial. Debido a esta presentación atípica, se retrasó el diagnóstico de arteritis de la temporal y tratamiento oportuno. Resultados: la arteritis de células gigantes es una patología que posee un gran rango de presentaciones atípicas, lo que ocurre en hasta un 38% de los pacientes que poseen la enfermedad, manifestaciones que incluyen neuralgia del trigémino, infartos linguales, aneurismas aórticos, edema facial, entre otros. Conclusión: es muy relevante conocer las presentaciones atípicas de esta patología que son muy frecuentes de encontrar en los pacientes y conocerlas nos permite aumentar nuestra sospecha clínica permitiendo un diagnóstico y tratamiento oportuno, evitando consecuencias irreversibles por el retraso diagnóstico.

Introduction: giant cell arteritis is the most frequent large vessel vasculitis and is seen predominantly in adults over 50 years. The diag-nosis is based on the clinic that is composed of headache, polymyalgia rheumatic, sensitivity near the temporal artery, compromise of the general condition, among other things, added to a laboratory that is evidenced like severe acute phase reactants and anemia and finally, is confirmed with temporal artery biopsy. Methods: a case report of a patient who debuted with headache and increased facial volume that led to a wrong diagnosis of facial cellulite. Because of this atypical presentation of the disease, the diagnostic took more time than usual and delayed the accurate diagnosis and timely treatment; this could have caused irreversible consequences. Results:giant cell arteritis has a wide range of atypical presentations; this may occur even up to 38% of patients that have this disease; manifes-tations include: trigeminal neuralgia, lingual infarct, aortic aneurysm, facial edema, and other symptoms. Conclusion: it is important to study the atypical presentations of this pathology because they are usually founded in patients. If we are informed about the atypical presentations, we can increase our clinical suspicion, and that allows us to get the right diagnosis and opportune treatment, avoiding irreversible consequences because of a late diagnosis.

Stroke and temporal arteritis: A study of 6 cases. / Arteritis temporal e ictus: análisis de 6 casos.

INTRODUCTION: Though uncommon, ischaemic stroke due to temporal arteritis carries serious difficulties for diagnosis and subsequent management and requires a high level of suspicion. METHODS: We analysed a series of 6 patients with biopsy-proven temporal arteritis presenting with ischaemic stroke. We discuss clinical characteristics, difficulties of assessment, short- and long-term progression, treatment, and the usefulness of new diagnostic techniques. RESULTS: Our sample of 6 patients had a mean age of 68.3 years; 50% were women. The majority of patients showed systemic symptoms. Anterior and posterior circulation were affected similarly. MRI angiography, Doppler sonography, and PET-CT proved to be very useful for diagnosis and treatment. Mean follow-up time was 26 months. Clinical outcomes were far from good: 33% scored≥3 on the modified Rankin scale, including one death. Two patients had recurrent stroke despite treatment with full doses of corticosteroids, and 2 underwent angioplasty. CONCLUSIONS: Stroke caused by giant cell arteritis is a serious and potentially severe condition which requires a high level of suspicion and early treatment with corticosteroids. New diagnostic techniques contribute to refining patient assessment and identifying the optimal treatment. Endovascular treatment may be a valid therapeutic option in selected patients.

Granuloma actinico de O'Brien / O'Brien actinic granuloma

Se comunica un caso de granuloma actínico en una paciente de sexo femenino, caucásica, la cual presentaba concomitantemente arteritis de la temporal y polimialgia reumática. Actualmente se considera que debido a la fisiopatogenia de las tres entidades mencionadas, podría tratarse la primera, de un marcador de las dos restantes.

We present a female, white, with an actinic granuloma, concomitantly with temporal arteritis and polymyalgia rheumatica. Today it is considered that, due to the phisiopathogenia of the three entities mentioned before, the first one could be used as a reference for the other two.
