Common Syndromes of Orthostatic Intolerance [PDF]

open access: yesPediatrics, 2013
The autonomic nervous system, adequate blood volume, and intact skeletal and respiratory muscle pumps are essential components for rapid cardiovascular adjustments to upright posture (orthostasis). Patients lacking sufficient blood volume or having defective sympathetic adrenergic vasoconstriction develop orthostatic hypotension (OH), prohibiting ...

A comparison of the upright seated versus left lateral decubitus position during pediatric sedation‐free transnasal endoscopy

open access: yesJPGN Reports, EarlyView.
Abstract Objectives Although sedation‐free transnasal endoscopy (TNE) is conventionally performed in an upright seated position in pediatric patients, emerging data suggest that the left lateral decubitus (LLD) position may improve both endoscopic visualization and patient comfort and safety.

Delayed Orthostatic Intolerance

open access: yesArchives of Internal Medicine, 1992
In seven patients who presented with lightheadedness, fatigue, "weakness," and sometimes syncope, blood pressure was found not to fall after standing for 3 to 4 minutes but to fall severely, frequently with syncope or presyncopal symptoms, after 13 to 30 minutes when measured every minute with an automatic device.

Patients with Orthostatic Intolerance: Relationship to Autonomic Function Tests results and Reproducibility of Symptoms on Tilt

open access: yesScientific Reports, 2017
This study was designed to investigate the frequency and pattern of orthostatic symptoms during head-up tilt (HUT) in patients with orthostatic intolerance during daily life, and to identify the relationship between the orthostatic symptoms during HUT ...

Impaired Cerebral Autoregulation during Head Up Tilt in Patients with Severe Brain Injury. [PDF]

open access: yesPLoS ONE, 2016
Early mobilization is of importance for improving long-term outcome for patients after severe acquired brain injury. A limiting factor for early mobilization by head-up tilt is orthostatic intolerance.

Neuromelanin‐Sensitive MRI as a Marker of Clinical Severity and Disease Burden in Parkinson's Disease: A Systematic Review and Meta‐analysis

open access: yesMovement Disorders, EarlyView.
Abstract The neuropathology of Parkinson's disease (PD) is characterized in part by the degeneration of catecholaminergic neurons, particularly dopaminergic neurons in the substantia nigra pars compacta (SNpc) and noradrenergic neurons in the locus coeruleus (LC), yet no validated in vivo biomarker quantifies this process.

A new insight on postural tachycardia syndrome in 102 adults with hypermobile Ehlers-Danlos Syndrome/hypermobility spectrum disorder

open access: yesMonaldi Archives for Chest Disease, 2020
There is an association between joint hypermobility, hypermobile Ehlers-Danlos syndrome (hEDS) and different forms of orthostatic intolerance. Objective: to explore autonomic profile in a large cohort of adults with hEDS and hypermobility spectrum ...

Parasympathetic dysfunction assessed by deep‐breathing CVR‐R is associated with early discontinuation of oral semaglutide in type 2 diabetes: A multicenter retrospective study

open access: yesJournal of Diabetes Investigation, EarlyView.
Lower CVR‐R during deep breathing (CVR‐R_DB), a marker of parasympathetic function, was associated with early discontinuation of oral semaglutide due to nausea and/or vomiting in patients with type 2 diabetes. CVR‐R_DB may support risk stratification at treatment initiation.

Postural orthostatic tachycardia syndrome in adolescents with ME/CFS — a case control study

open access: yesFrontiers in Pediatrics
IntroductionPostural orthostatic tachycardia syndrome (PoTS) can be associated with myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS). Pediatric PoTS requires a “sustained” rise in orthostatic heart rate ≥40 bpm above supine heart rate ...
