Abstract

Several studies recognized an overlap between CFS (chronic fatigue syndrome) and POTS (postural tachycardia syndrome). We compared the autonomic and neurohormonal phenotype of POTS patients with CFS (CFS–POTS) to those without CFS (non-CFS–POTS), to determine whether CFS–POTS represents a unique clinical entity with a distinct pathophysiology. We recruited 58 patients with POTS, of which 47 were eligible to participate. A total of 93% of them reported severe fatigue [CIS (Checklist of Individual Strength), fatigue subscale >36], and 64% (n=30) fulfilled criteria for CFS (CFS–POTS). The prevalence of CFS symptoms (Centers for Disease Control and Prevention criteria) was greater in the CFS–POTS group, but the pattern of symptoms was similar in both groups. Physical functioning was low in both groups (RAND-36 Health Survey, 40±4 compared with 33±3; P=0.153), despite more severe fatigue in CFS–POTS patients (CIS fatigue subscale 51±1 compared with 43±3; P=0.016). CFS–POTS patients had greater orthostatic tachycardia than the non-CFS–POTS group (51±3 compared with 40±4 beats/min; P=0.030), greater low-frequency variability of BP (blood pressure; 6.3±0.7 compared with 4.8±1.0 mmHg2; P=0.019), greater BP recovery from early to late phase II of the Valsalva manoeuvre (18±3 compared with 11±2 mmHg; P=0.041) and a higher supine (1.5±0.2 compared with 1.0±0.3 ng/ml per·h; P=0.033) and upright (5.4±0.6 compared with 3.5±0.8 ng/ml per h; P=0.032) PRA (plasma renin activity). In conclusion, fatigue and CFS-defining symptoms are common in POTS patients. The majority of them met criteria for CFS. CFS–POTS patients have higher markers of sympathetic activation, but are part of the spectrum of POTS. Targeting this sympathetic activation should be considered in the treatment of these patients.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Patients with POTS often have exercise intolerance, more than 90% have chronic fatigue, and at least half meet criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

    “Patients with POTS often have exercise intolerance, more than 90% have chronic fatigue and at least half meet criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).18”

    From Diagnosis and management of postural orthostatic tachycardia syndrome (2022) · cites this paper as [18]

    The Results report severe fatigue in 93% of the POTS patients, and the Discussion reports that 64% met CDC criteria for CFS. But severe fatigue is not the same as chronic fatigue: the Introduction gives a 48–77% chronic-fatigue prevalence in earlier POTS cohorts, and the Results say some patients’ fatigue lasted less than six months. The paper describes impaired physical functioning and exercise-related fatigue, but does not establish how often patients have exercise intolerance. Page numbers were not available in our copy.

  • POTS and CFS may exist along the same clinical spectrum.

  • Patients with POTS may simultaneously meet diagnostic criteria for migraine, hypermobile Ehlers-Danlos syndrome, mast cell activation syndrome, or chronic fatigue syndrome.

    “Patients with POTS may simultaneously meet the diagnostic criteria for migraine, hypermobile Ehlers-Danlos syndrome (hEDS), mast cell activation syndrome (MCAS) or chronic fatigue syndrome (CFS) (Kavi et al., 2016; McDonald et al., 2014; Okamoto et al., 2012; Shaw et al., 2019).”
  • POTS patients have a high prevalence of chronic fatigue (48-77%) and of CFS (17-23%).

    “Patients with POTS have a high prevalence of chronic fatigue (48-77%) and of CFS (17-23%) [33;8].”
  • Autonomic testing indicated a similar autonomic profile but higher sympathetic tone in POTS patients with CFS.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
