RIVERO PUENTE, A. et al. Arteritis de células gigantes y polimialgia reumática: diagnóstico y evolución de 90 casos. []. , 18, 4, pp.27-30. ISSN 0212-7199.

^les^aObjetivo: Comparar el cuadro clínico de la arteritis de células gigantes (ACG) y el de la polimialgia reumática (PMR). Valorar los criterios diagnósticos del American College of Rheumatology contrastándolos con nuestros resultados.  Pacientes y métodos: Estudio retrospectivo de 90 enfermos diagnosticados de ACG (n = 57,55 diagnosticados por biopsia) y de PMR (n = 33) en los últimos 10 años.  Resultados: Presentaron cefalea 45 enfermos (78,94%) con ACG y 7 (21,21%) con PMR (p<0,001), síndrome polimiálgico 15 (26,31%) con ACG y 33 (100%) con PMR (p<0,001), claudicación mandibular o lingual 14 (24,57%) con ACG y 2 (6,06%) con PMR (p<0,05) y alteraciones visuales 9 (15,79%) con ACG. La VSG fue = 50 mm/h en 84 enfermos (93,33%) y = 100 mm/h en 43 de ellos (51,19%). La VSG se normalizó (£ 20 mm/h) en menos de 8 semanas en 64 enfermos (76,19%). En el momento del diagnóstico 61 enfermos (61,77%) presentaron anemia, 17 de ellos (27,86%) de grado severo (Hb < 10 g/dl). Tras tratamiento esteroideo se recuperaron de la anemia 43 enfermos (70,49%), todos en menos de 12 semanas y 25 (58,13%) en menos de 8 semanas.  Conclusiones: Los síntomas cefálicos orientaron el diagnóstico en la ACG y son predictivos de biopsia de arteria temporal positiva. La anemia y su rápida normalización tras tratamiento exclusivo con glucocorticoides son datos que pueden ayudar en el diagnóstico de estas entidades.^len^aObjective: To compare the clinical features of giant cell arteritis (GCA) and polymyalgia rheumatic (PMR), and to evaluate the criteria proposed by the American College of Rheumatology in our results.  Patients and methods: A retrospective analysis of 90 patients with GCA (n = 57,55 of whom were diagnosed by biopsy) and PMR (n = 33) diagnosed over the last 10 years.  Results: Headache was present in 45 patients (78.94%) with GCA and in 7 (21.21%) with PMR (p<0.001); polymyalgic syndrome was observed in 15 patients (26.31%) with GCA and in 33 (100%) with PMR (p<0.001); jaw or tongue claudication was observed in 14 patients (24.57%) with GCA and in 2 (6.06%) with PMR (p<0.05), and visual disturbances were only present in 9 patients (15.79%) with GCA. The erythrocyte sedimentation rate (ESR) was = 50 mm/h in 84 patients (93.33%), and = 100 mm/h in 43 of them (51.19%). The ESR became normal (£ 20 mm/h) in less of 8 weeks after the treatment was started in 64 patients (76.19%). At the time of diagnosis, 61 patients (61.67%) had anemia, which was severe (Hb < 10 g/dl) in 17 cases (27.86%). After steroid treatment 43 patients (70.49%) improved their anemia in less of 12 weeks, and 25 of them (58.13%) in less of 8 weeks.  Conclusions: The cranial symptoms were predictive for a positive temporal artery biopsy. The anemia and its quick normalitation after steroid treatment can help to the diagnostic.
