Postural Orthostatic Tachycardia Syndrome (POTS) affects approximately 500,000 - 3 million Americans. This number will only increase due to the large number of patients experiencing POTS due to "long COVID." POTS patients experience several symptoms, including tachycardia, palpitations, dizziness, and pre-syncope or syncope, among others.

POTS patients seem to experience orthostasis-dependent muscle weakness and pain as well as increased muscle fatigue upon physical activity, which can be improved by regular aerobic exercise. However, reduced sweat production of the extremities with limited control of the body temperature leads to exercise intolerance, so that sticking to a training program becomes a challenge for most patients.

These non-motor symptoms tend to manifest before the motor symptoms and progressively worsen over time, significantly impacting the symptoms and everyday life activities of those affected.

Postural orthostatic tachycardia (POTS) is characterized by abnormalities in the autonomic nervous system in the body. The autonomic nervous system controls and regulates body functions such as heart rate, breathing, digestion, and more. The investigator has shown that patients with POTS have higher cardiovascular and adrenergic activating autoantibodies (AAb), which likely changes the normal make-up of POTS.

Physical activity helps to improve health and prevent chronic diseases. However, the fatigue usually hampers the training and execution of physical exercises, especially in people with chronic fatigue syndromes (CFCs), such as persons living with HIV (PLWH).

Mastocytosis is a rare condition characterized by an accumulation of mast cell cells in one or more organs such as the liver, bone marrow, spleen and intestines. Its prevalence in the general population is 1 in 10,000. This pathology is due to the proliferation of a mast cell clone and the excessive release of inflammatory mediators which lead to abnormal tissue infiltration.

The syndrome characterized by the persistence of symptoms typical of COVID-19, beyond 4 weeks after discharge, is called long COVID. Long COVID affects a high percentage of patients who have suffered from COVID-19, regardless of its severity. The various symptoms present in that patients affect the functionality and physical, mental and psychological capacities of patients.

Funding Source- FDA OOPD.

Patients with Postural Tachycardia Syndrome (POTS) may not adequately expand their plasma volume in response to a high sodium diet. Mechanisms involved in the regulation of plasma volume, such as the renin-angiotensin-aldosterone system and renal dopamine (DA), may be impaired in POTS and may respond inappropriately to changes in dietary sodium.

The purpose of the proposed research is to determine how changes in kidney dopamine (DA) activity influence urinary sodium excretion. We will decrease DA activity in the kidney by inhibiting DA synthesis via carbidopa administration. We want to compare findings in normal volunteers and in patients with postural tachycardia syndrome (POTS).
