Autoimmunity Causes Exertion Problems in CFS, FMS, POTS

Exercise Tests Suggest Autoimmunity Causes the Exertion Problems in Chronic Fatigue Syndrome, Fibromyalgia and POTS – Health Rising – by Cort Johnson | Aug 16, 2017

Researchers and doctors get interested in ME/CFS in different ways. Many have a personal connection, but for David Systrom,  a pulmonologist, it was all about demand.

He didn’t seek chronic fatigue syndrome patients out – quite the contrary.  When Systrom was given control of a clinical cardiopulmonary lab, he started doing invasive cardiopulmonary exercise tests (iCPET’s) on people with exercise intolerance.

EDS linked to Orthostatic Intolerance and POTS

Orthostatic Intolerance and Postural Orthostatic Tachycardia Syndrome in Joint Hypermobility Syndrome/Ehlers-Danlos Syndrome, Hypermobility Type: Neurovegetative Dysregulation or Autonomic Failure?  – Biomed Res Int. – Feb 2017 – free full-text PMC article

Joint hypermobility syndrome/Ehlers-Danlos syndrome, hypermobility type (JHS/EDS-HT), is a hereditary connective tissue disorder mainly characterized by

  • generalized joint hypermobility,
  • skin texture abnormalities, and
  • visceral and vascular dysfunctions,
  • also comprising symptoms of autonomic dysfunction.

This study confirms the abnormal cardiovascular autonomic profile in adults with JHS/EDS-HT and found the higher baroreflex sensitivity as a potential disease marker and clue for future research.  Continue reading

Recognizing postural orthostatic tachycardia syndrome

Recognizing postural orthostatic tachycardia syndrome : Journal of the American Academy of Physician Assistants

This article describes the pathophysiology, clinical presentation, differential diagnosis, diagnosis, and management of postural orthostatic tachycardia syndrome (POTS), a potentially debilitating autonomic disorder that can have many causes and presentations.

POTS can be mistaken for panic disorder, inappropriate sinus tachycardia, and chronic fatigue syndrome.

Clinician suspicion for the syndrome is key to prompt patient diagnosis and treatment.   Continue reading

Dysautonomia: Types and Symptoms

Dysautonomia: Types, Symptoms, and Treatments – Medical News Today

Dysautonomia is not a single disorder, the term describes a number of conditions which affect the autonomic nervous system. This section of the nervous system controls automatic body functions, like heart rate and breathing.

dysautonomia affects an estimated 70 million people worldwide.

In this article, we will describe some of the different types of dysautonomia, their symptoms, and treatments.   Continue reading

Tricyclic Antidepressants: The Good, the Bad, and the Potentially Ugly

Tricyclic Antidepressants in Neuropathic Pain: The Good, the Bad, and the Potentially Ugly | Pharmacy Times | Kelsie Flynn, PharmD

Antidepressant Efficacy in Neuropathic Pain

Although clinicians are able to identify the causes of neuropathic pain, the mechanism behind its treatment is more difficult to distinguish.

The drugs’ potential analgesic properties were noted long before in a study published in 1960.

Although tricyclic antidepressants remained the mainstay of pharmacological treatment for neuropathic pain for years, the drugs’ true mechanism wasn’t revealed until 1992.   Continue reading

Dysautonomia 101

Dysautonomia 101 From Lauren Stiles For Chronic Fatigue Syndrome and Fibromyalgia – Health Rising

Dysautonomia is an umbrella term that means any dysfunction of the Autonomic Nervous System (ANS).  The ANS controls the involuntary functions of the body like heart rate, blood pressure, breathing, digestion, sweating, kidney function, dilation and constriction of the pupils and more.

Common Tragedies Of Lax Joint Syndromes

Common Tragedies Of Lax Joint Syndromes: Broken Hearts, Fallen Men, And Loose Women | Consultant360 | 02/23/15

This is an excellent and thorough explanation of EDS and other Connective Tissue Disorders (CTDs):

Joint laxity syndromes can cause many nonspecific and variable symptoms, even among patients with the same condition, making diagnosis difficult.

Many patients see numerous specialists before receiving a proper diagnosis, as many healthcare providers are only familiar with the more extreme forms of the disease (eg, Marfan syndrome, osteogenesis imperfecta) despite milder variants being more prevalent.

This article provides an overview of the spectrum of joint laxity syndromes, examining symptoms, assessment, and workup of patients suspected to have such conditions. It also provides an overview of the role of genetic testing and of the preventive and therapeutic strategies physicians can use to improve the care of their patients.   Continue reading

Joint hypermobility: emerging disease or illness behaviour?

Joint hypermobility: emerging disease or illness behaviour | by Rodney Grahame

Joint hypermobility syndrome is a common clinical entity which is much misunderstood, overlooked, misdiagnosed and mistreated. It was first described in the 1960s as a purely musculoskeletal condition due to joint laxity and hypermobility occurring in otherwise healthy individuals.

Some four decades later it is now perceived to be a multi-systemic heritable dis- order of connective tissue with manifestations occurring far beyond the confines of the locomotor system and with ramifications potentially affecting most, if not all, of the bodily systems in one way or another.

Most authorities in the field find it clinically indistinguishable from EDS type III, the Ehlers-Danlos syndrome hypermobility type.

In > 50% of patients the diagnosis is delayed for 10 years. Failure to diagnose and treat the condition correctly results in needless pain and suffering and in many patients to a progressive decline in their quality of life and in some to a loss of independence.   Continue reading

POTS a suspected adverse effect of HPV vaccination?

Orthostatic intolerance and postural tachycardia syndrome as suspected adverse effects of vaccination against human papilloma virus. – PubMed – NCBI

From what I’ve heard in the community, this is highly unlikely. Their suspicions are quite a stretch, and even the association doesn’t hold up, let alone causation.

POTS has been around a lot longer than this vaccine.

BACKGROUND: Infections with human papilloma virus (HPV) can result in cervical, oropharyngeal, anal, and penile cancer and vaccination programs have been launched in many countries as a preventive measure.

We report the characteristics of a number of patients with a syndrome of orthostatic intolerance, headache, fatigue, cognitive dysfunction, and neuropathic pain starting in close relation to HPV vaccination.  Continue reading

Hyperadrenergic POTS: Clinical presentation and mgmt

Clinical presentation and management of patients with hyperadrenergic postural orthostatic tachycardia syndrome | June 2011

In recent years there has been a substantial improvement of our understanding of POTS. Although the exact etiology remains elusive, we know that the syndrome of postural tachycardia is not a single clinical entity, but rather a heterogeneous group of various related clinical syndromes having a final common presentation of orthostatic intolerance

The commonest form of POTS, called the neuropathic or partial dysautonomic form, results from neuropathy preferentially involving the lower extremities with resultant venous pooling

Another group of patients suffer from centrally driven abnormal sympathetic activation. This form of postural tachycardia syndrome is called hyperadrenergic POTS, and comprises about 10% of all POTS patients. Patients suffering from hyperadrenergic POTS have been observed to have an orthostatic plasma norepinephrine level =600 pg/mL and a rise of systolic blood pressure (SBP) of =10 mm Hg upon standing.
