Background:Giant cell arteritis (GCA) is a vasculitis that affects the medium and large vessels (LV). Although cranial artery involvement is better known, awareness of the importance of LV involvement is increasing. Imaging techniques currently constitute the basis for the diagnosis of LV-GCA and have improved its diagnosis and prevalence. In recent years, differences in clinical patterns and different inflammatory and etiopathogenic mechanisms of the disease have been suggested. Therefore, improving sensitivity to diagnosis is essential to improve the knowledge and care of our population.Objectives:The aim of this study was to know the prevalence of the different ultrasound patterns of GCA in our area.Methods:Retrospective records of available data were collected from all patients referred to our ACG fast track clinic in the past three years. The clinical and laboratory characteristics were evaluated at the time of referral. All patients underwent an ultrasound scan of cranial vessels (superficial temporal arteries (TA) and their frontal and parietal branches) and large vessels (axillary, subclavian and carotid arteries). The doctor confirmed the GCA diagnosis after at least six months of follow-up. The OMERACT definitions of halo sign with a hypoechoic wall thickness ≥ 0.34 mm were used for TA pathology for the ultrasound diagnosis of GCA and for axillary, subclavian and carotid arteries and homogeneous hypoechoic thicknesses ≥ 1 mm of the arterial wall were applied. Atherosclerosis lesions were evaluated to detect this disease as a possible false positive halo sign. An Esaote Mylab Twice with a 13 MHz probe in BT and 22 MHz for cranial vessels in 2017-2019 and an Esaote Mylab X8plus with a 15 MHz probe for BT and a 24 MHz probe for cranial arteries in 2019-2020 were used by two rheumatologist with long experience in ACG ultrasound.Results:A total of 261 patients (180 women / 81 men) with suspected GCA were evaluated in our fast track clinic. The mean age (± SD) was 76 ± 9.2 years and CRP at diagnosis was 75.7 ± 68.6 mg/L. The time elapsed since the first symptoms was less than 6, 6-12, 12-24 or >24 weeks in 37.5%, 19.9%, 12.3% and 15.7% respectively. Of the 261 cases explored, 160 had GCA, of which 102 were women and 58 men, and had a mean age of 77.21 ± 7.9 years. The ultrasound patterns of GCA were: 71 patients had exclusive involvement of the TA (cranial-GCA), 54 had a mixed pattern with involvement of both TA and LV (mixed-CGA), and 35 had isolated involvement of the LV (LV-GCA). That is, 125 patients had cranial involvement with or without LV involvement and 89 had LV-GCA associated or not with cranial involvement (Figure 1).Figure 1.Ultrasound patters of GCAConclusion:Ultrasound is a useful tool for the screening of GCA and its different subtypes of vascular involvement. The isolated cranial subtype or associated with LV-GCA is the most common (78% of cases), but LV-GCA is also very common (55.6% of cases of GCA) and 21.9% presents as an isolated LV-GCA standard. The LV arteries should be included in the ultrasound examination for suspected GCA.Disclosure of Interests:Irene Monjo Speakers bureau: Roche, Novartis, UCB, Gedeon Richter, Consultant of: Roche, Elisa Fernández-Fernández: None declared, Javier Ortega: None declared, Eugenio de Miguel Speakers bureau: AbbVie, Novartis, Pfizer, MSD, BMS, UCB, Roche, Grunental, Janssen, Sanofi, Paid instructor for: Janssen, Novartis, Roche, Consultant of: AbbVie, Novartis, Pfizer, Galapagos, Grant/research support from: Abbvie, Novartis, Pfizer

Abstract Introduction/Objective Giant cell arteritis (GCA) is the most common vasculitis of the elderly, and the most common primary systemic vasculitis overall, with an annual incidence of 200/million. The long term sequelae, namely vision loss and stroke, are permanent and devastating. While GCA is often treated empirically based on clinical presentation, panarteritis on temporal artery biopsy is required for diagnosis. However, these biopsies have the tendency to be falsely negative due to skip lesions, a common feature of GCA. Therefore, we set out to determine whether longer biopsy specimens were more sensitive in the detection of GCA. Methods/Case Report A census of temporal artery biopsies performed with the indication of clinical symptoms of GCA was taken at our institution. The patient age, sex, biopsy laterality, biopsy length, and pathological diagnosis were recorded for each cataloged sample. Statistical significance of difference in biopsy length was tested using an unpaired t-test in R 4.1.0. Results (if a Case Study enter NA) A total of 114 temporal artery specimens were biopsied from 94 different patients with the indication of GCA and assigned a definitive positive or negative diagnosis. Of the 94 patients, 54 were female and 40 were male. Of the total pathological specimens, 11 were positive and 103 were negative. The overall average length of biopsy specimens was 2.13 cm with a standard deviation of 0.65 cm. The average positive biopsy was 2.26 cm long, and the average negative was 2.12 cm, an insignificant difference (0.14 cm, t = 0.7, p = 0.43). In 25 patients, biopsies were taken from both the left and right temporal arteries. Of those patients, 2 were positive for GCA and the remaining 23 were negative. Interestingly, the biopsy result in every case was identical between the left and right samples; we found no instances of pathological evidence of GCA in only one of the two samples from the same patient. Conclusion According to data taken at our institution, there is no indication to lengthen the biopsy requirements from the existing 1.5 cm. However, we have demonstrated evidence that it may be unnecessary to biopsy both temporal arteries in a single patient. Larger studies would be required to confirm our findings.
