BACKGROUND: Evaluate the incidence of biopsy-proven giant cell arteritis (GCA) for seasonal or annual variability from a tertiary care center in the Mid-Atlantic United States. DESIGN: Retrospective chart review of all patients seen in the Neuro-Ophthalmology Service undergoing temporal artery biopsy (TAB) from 1994 to 2011. PARTICIPANTS: The charts of 744 patients were reviewed and 215 patients were diagnosed with GCA based on positive TAB results. METHODS: All results between 1994 and 2011 were reviewed. GCA incidence data was evaluated by year, season, and month for any trends or cyclic patterns. A subset of clinical charts was reviewed to determine time from symptoms to diagnosis. MAIN OUTCOME MEASURE: Incidence of biopsy proven GCA. RESULTS: The majority of patients were female (74%) and over the age of 60 (98.6 %). The diagnosis of biopsy-proven GCA was found in 215 of 744 (28.9%) patients. The incidence of biopsy proven GCA by year varied, with the peak incidence in 1996. The monthly incidence peaked in July and had a trough in October. However, Poisson regression analysis did not show any statistically significant trend over time or cyclic pattern to the incidence by year, season, or month. CONCLUSION: The incidence of biopsy-proven GCA in the population studied did not have any significant cyclic pattern over the last 17 years. The highest incidence by month was noted in July with a trough in October. However, this was not a significant pattern by month or season to support infectious or periodic environmental factors inciting GCA.
