Popis: Background/Aims Giant cell arteritis (GCA) is the most common vasculitis in adults aged over 50 years old with the highest incidence among persons aged 70-79. It is more commonly seen in female patients. Most cases have been reported in whites of Northern European descent. A broad range of symptoms can be reported including headache, jaw or tongue claudication, visual disturbances, PMR and other systemic features including weight loss, fever and sweats. In recent years new evidence has emerged regarding the investigation and treatment of GCA. This audit is to review the demographics, symptoms and investigations of patients who presented to the Rheumatology Department in SEHSCT with features concerning for possible GCA. Methods Retrospective collection of data from January 2020 to July 2021 using the regional Electronic Care Record NI with reference to presentations, investigation results, clinic records and follow-up letters. Results 70 patients were included (24 males and 46 females). Mean age was 72 years old. Table 1 shows the percentages of clinical symptoms reported. All patients investigated had an ESR (mean 57.8) and CRP (mean 54.1) checked. 43 patients had ANCA checked with 3 positive results. 40 patients underwent CT brain with 2 abnormalities reported unrelated to GCA. TA ultrasound was performed on one occasion with a positive result demonstrating “halo” sign recorded. 6 patients underwent CTPET with 3 diagnoses of LVV and 1 of PMR. 70 TAB performed with 12 positive results and 4 ‘suggestive’ of GCA. Conclusion Our cohort of patients demonstrated demographics similar to the current global geographic trends in GCA. There are a broad range of clinical symptoms that can present in GCA, none of which are entirely specific or pathognomonic. Clinical diagnosis is based on clinical symptoms, signs and laboratory tests, each of which are imperfect markers for GCA. Our audit demonstrated that the use of additional confirmatory diagnostic tests including temporal artery ultrasound and CTPET was being under-utilized in the SEHSCT. Use of these tests may improve the diagnostic yield in this challenging condition. As a result of this audit, a quality improvement project to provide a rapid access GCA pathway is being designed.
