35 Total-body symptom assessment in patients with idiopathic orthostatic intolerance to improve symptomatic management

OBJECTIVES/GOALS: Total-body symptom surveys among patients with idiopathic orthostatic intolerance (OI) at our referral center suggest that non-conventional OI symptoms, such as pelvic pain, impact quality of life. We seek to identify additional common yet unconventional symptoms reported during clinic visits to improve targeted symptom management. METHODS/STUDY POPULATION: Pelvic pain symptom surveys were completed by 178 patients age 18 and over with a chief complaint of OI. Pelvic pain prevalence was assessed using the International Pelvic Pain Society (IPPS) and Pelvic Congestion Syndrome (PCS) surveys. Expanding on this work, surveys will be distributed to a population with the same inclusion criteria but with a broader symptom scope, chosen based on patient reports during clinical encounters—including presence of migraines, cold digits (Raynaud’s phenomenon), anxiety and depression. The Migraine Disability Assessment Test (MIDAS), modified Assessment of Systemic Sclerosis–Associated Raynaud’s Phenomenon (ASRAP), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9) surveys, respectively, will be used to obtain symptom prevalence. RESULTS/ANTICIPATED RESULTS: Of the pelvic pain survey participants, pelvic pain was endorsed by 144/178 (80.9%) of respondents. Prevalence of the additional surveyed symptoms—migraines, cold digits, anxiety, and depression—will similarly be assessed. Given that in our referral clinic we have observed a trend of patients reporting these additional symptoms, we anticipate that at least some of them will be prevalent in a majority of the patient population formally surveyed, similar to the trend observed with pelvic pain prevalence. In particular, we anticipate many patients will report significant migraines, as migraine pain severity on a scale of 0-10 with 0 being no migraine pain and 10 being the most severe migraine pain imaginable is one of the elements of the IPSS survey, and 106/178 (59.6%) reported migraine pain of 5 or higher. DISCUSSION/SIGNIFICANCE: Novel treatment approaches for OI are needed, as lifestyle management is the current treatment paradigm. Several patients reporting pelvic pain have undergone targeted workup and subsequent symptomatic treatment that has improved their quality of life. Other targeted symptom approaches to prevalent symptoms could have the same effect.
