Standing Up To POTS has awarded grants to research teams across the globe.
POTS is a complex chronic illness that often has comorbidities including Long COVID. Dr. Pretorius' lab seeks to better understand coagulation dynamics and endothelial health in the development of microclots. Their aim is to characterize these microclots and the inflammatory molecules within them to inform more targeted diagnostic and treatment strategies.
Diagnosis continues to elude far too many POTS patients. Dr. Maier's research team seeks to establish a rapid diagnostic process for diagnosing POTS that can be used in any healthcare practitioner's office. They hope is to normalize and quicken the diagnosis of POTS so that proper treatment may begin.
For approximately 40% of POTS patients, regular fainting is a problem. Dr. Wang's team plans to develop a wearable device that can predict a fainting episode in POTS patients 2-3 minutes in advance. This could be a game changer for many with POTS, allowing them to get into a safe position and hopefully prevent the faint from occurring at all.
The underlying cause of hyperventilation upon standing in many POTS patients is not well understood. Dr. Raj and his team will seek to manipulate carbon dioxide levels in the blood upon standing to better understand the role that chemoreceptors play in POTS symptomology and to explore potential new treatments for POTS patients.
Their project will take an informatics approach to choosing the right treatment for individual postural orthostatic tachycardia syndrome (POTS) patients based on clinical subgroups. We are really excited about the possibility that data can be used to determine best practices for treating patients with particular clusters of symptoms.
The aim is to study POTS in Long COVID syndrome with a comprehensive look at inflammation, neuroendocrine dysfunction, and autoimmunity post-COVID infection. The silver lining in this pandemic is that there are many new POTS patients that can be studied where the trigger of symptom onset is known and can be quantified. Approximately 40% of all POTS patients develop symptoms post infection, so we hope that this research will help a large proportion of current POTS patients.

A variety of physiological variables will be monitored and recorded in real time 24 hours a day to better determine physiological and psychological fluctuations in POTS patients.

The overall aim of this study is to examine how hormonal changes related to a woman's menstrual cycle affect symptoms of POTS, and whether the time of the month matters in diagnosis POTS for women of childbearing age. Further, a novel therapy for alleviating symptoms will be tested.

Many patients with POTS report attention deficits and “brain fog” with problems in their everyday life and work, predominantly in upright posture. Specific symptomatic or medical therapies do not exist. This study will investigate problems of concentration, attention and/or cognitive dysfunction in people with POTS, autoimmune autonomic neuropathy, small fiber neuropathy and Ehlers-Danlos Syndrome compared to healthy controls.

This study examines the connection between Lyme Disease and POTS, a particularly important issue for our friends in the Northeastern United States and other places where Lyme disease is prevalent.
