Oral or pulse glucocorticoid use at the onset of giant cell arteritis and its influence on the risk of relapse: a retrospective study.

The objective is to investigate whether initial therapy with intravenous methylprednisolone pulses (ivMTP) or oral glucocorticoid (OG) influences the relapse rate in giant cell arteritis (GCA) patients. This is a retrospective observational study of patients with GCA from 2004 to 2021. Demographics, clinical and laboratory variables, cumulative glucocorticoid dose and relapse rate at 6-month follow-up defined according to EULAR recommendations were recorded. Univariate and multivariate logistic regression models were used to determine possible risk factors for relapse. A total of 74 GCA patients were included for analysis (54 (73%) female, mean (SD) age 77.2 (7.4) years). Overall, 47 (63.5%) patients received ivMTP at disease onset and 27 (36.5%) OG. Mean (SD) cumulative prednisone dose (mg) at 6-month follow-up was 3790.7 (1832.7) for patients with ivMTP vs 4298.1 (2930.6) for the OG group, p = 0.37. A total of 15 (20.3%) relapses occurred at 6-month follow-up. Relapse rates did not differ according to the initial therapy (19.1 vs 22.2%, respectively, p = 0.75). In the multivariate analysis, fever at disease onset (OR 4.837; CI 1.1-21.6) and dyslipidemia (OR 5.651; CI 1.1-28.4) were independent predictors for relapse. Initial therapy with ivMTP or OG does not influence the relapse rate of GCA patients. Fever at disease onset and dyslipidemia are independent predictors of disease relapse.

Impact of cardiovascular risk on the diagnostic accuracy of the ultrasound Halo Score for giant cell arteritis.

OBJECTIVE: To evaluate the impact of cardiovascular risk (CVR) on the diagnostic accuracy of the ultrasonographic (US) Halo Score in patients with suspected giant cell arteritis (GCA). METHODS: Retrospective observational study of patients referred to our US fast track clinic with suspected GCA for a 2-year period. The intima-media thickness (IMT) of cranial and extra-cranial arteries and the Halo Score was determined to assess the extent of vascular inflammation. The European Society of Cardiology Guidelines on CV Disease Prevention were used to define different categories of CVR and patients were classified according to the Systemic Coronary Risk Evaluation (SCORE). The gold standard for GCA diagnosis was clinical confirmation after a 6-month follow-up. RESULTS: Of the 157 patients included, 47 (29.9%) had GCA after a 6-month follow-up. Extra-cranial artery IMT was significantly higher in patients with high/very high CVR than in those with low/moderate CVR, but only among patients without GCA. Non-GCA patients with high/very high CVR had also a significantly higher Halo Score in contrast with low/moderate CVR [9.38 (5.93) vs 6.16 (5.22); p = 0.007]. The area under the ROC curve of the Halo Score to identify GCA was 0.835 (95% CI 0.756-0.914), slightly greater in patients with low/moderate CVR (0.965 [95% CI 0.911-1]) versus patients with high/very high CVR (0.798 [95% CI 0.702-0.895]). A statistically weak positive correlation was found between the Halo Score and the SCORE (r 0.245; c = 0.002). CONCLUSIONS: Elevated CVR may influence the diagnostic accuracy of the US Halo Score for GCA. Thus, CVR should be taken into consideration in the US screening for GCA.

Radiosynovectomy in routine care: an old tool with modern applications.

OBJECTIVES: Radiosynovectomy can be an effective treatment for difficult-to-treat monoarthritis resistant to systemic and local standard therapy. The objective of our study was to determine predictors of good response to radiosynovectomy in routine care and give an overview of this underused technique. METHODS: Retrospective observational study of all the patients who underwent radiosynovectomy during a 6-year inclusion period. All the procedures were ultrasound guided and the radiopharmaceutical used was chosen according to joint size. The patient was considered to have an effective response to radiosynovectomy if the attending physician reported a positive outcome and there was no need to increase local and or systemic treatment due to arthritis in the affected joint during the next 12 months following the procedure. RESULTS: We included 67 patients who underwent radiosynovectomy in the knee (73.1%), wrist (16.4%), and elbow (10.5%). Overall, 44 (65.7%) procedures were considered effective. In the multivariate analysis, infiltration of wrists (odds ratio = 0.192; confidence interval = 0.046-0.79) and pigmented villonodular synovitis (odds ratio = 0.13; confidence interval = 0.021-0.82) were independently associated with a noneffective response. No patients experienced complications associated with radiosynovectomy during follow-up. CONCLUSION: Infiltrations of wrists with joint damage seem less likely to have a response to radiosynovectomy. In pigmented villonodular synovitis, radiosynovectomy as an adjuvant therapy for relapse might not be effective when performed more than 6 months after surgery. Overall, radiosynovectomy is an effective and safe treatment for persistent monoarthritis.

Impacto clínico de la capilaroscopia periungueal en la práctica clínica diaria / Clinical impact of nailfold capillaroscopy in daily clinical practice

Introducción: La capilaroscopia periungueal (CP) es útil en la evaluación del fenómeno de Raynaud tanto primario como secundario, y en el seguimiento de los pacientes con esclerosis sistémica. Nuestro estudio evalúa el impacto de la CP en el diagnóstico, en función del motivo de solicitud y el perfil de autoanticuerpos en la práctica clínica diaria. Material y métodos: Se incluyeron todos los pacientes con al menos una CP entre junio de 2012 y diciembre de 2017. Se revisaron las historias clínicas y se determinó de forma dicotómica (sí/no) si la CP contribuyó al diagnóstico realizado en la consulta posterior a la realización de la CP. Se recogieron datos demográficos, clínicos y de laboratorio, motivo de solicitud de la CP y su relación con los patrones CP. Resultados: De 530 pacientes con una primera CP, 266 se realizaron como estudio de un fenómeno de Raynaud. De estos, en 20 pacientes (3,8%) se realizó un diagnóstico de enfermedad del tejido conectivo en la consulta posterior a la CP; 15 fueron diagnosticados de esclerosis sistémica, 4 de conectivopatía indiferenciada y uno de enfermedad mixta. Salvo un paciente diagnosticado de conectivopatía indiferenciada, el resto tenía anticuerpos antinucleares positivos y 11 de ellos, además, anticuerpos específicos (9 anticentrómero, uno anti-Scl70 y otro, anti-RNPC). La positividad de anticuerpos antinucleares se asoció con una mayor probabilidad de presentar una CP de esclerodermia, y ningún paciente diagnosticado de una enfermedad reumática tras la CP tenía un patrón normal. Conclusión: La CP es una técnica útil, pero con impacto limitado en el diagnóstico de enfermedades del tejido conectivo. La positividad de los anticuerpos se relaciona con una mayor probabilidad de presentar patrones patológicos en la CP.(AU)

Introduction: Nailfold capillaroscopy (NC) is useful in the evaluation of Raynaud's phenomenon, associated with some connective tissue diseases and in the follow-up of patients with systemic sclerosis. Our study evaluates the impact of NC in the diagnosis, according to the reason for the request and profile of autoantibodies in daily clinical practice. Material and methods: All patients that undergone at least one NC between June 2012 and December 2017 were included. Clinical records were reviewed and analysed in a dichotomous way (yes/no), to see whether the NC contributed to a change of diagnosis in subsequent consultations. In addition, demographic, clinical and laboratory data were collected, and the relationship with NC patterns evaluated. Results: Of the 530 patients who had undergone at least one NC, 266 had Raynaud's phenomenon as primary indication for the technique. Of those, 20 patients (3.8%) had a diagnostic change in the post-NC consultation; 15 were diagnosed with systemic sclerosis, 4 with undifferentiated connective tissue disease and one with mixed connective tissue disease. All patients had, except for one patient diagnosed with undifferentiated connective tissue disease, positive antinuclear antibodies titres, 11 of them had disease specific antibodies (9 anti-centromere, one anti-Scl70 and other anti-RNPC). The positivity of antinuclear antibodies titres was associated with a higher probability of presenting a scleroderma pattern in the NC, and all patients with a specific rheumatological diagnosis had an abnormal NC. Conclusion: NC is a useful technique, but with limited impact in the diagnosis of connective tissue diseases. Autoantibody positivity is associated with a greater likelihood of presenting pathological NC patterns.(AU)
