Chu e.a.

wekken ten onrechte

de suggestie dat

SEID

ME-ICC en

ME/CVS-CCC

kan vervangen

 

 

 

 


 

 

 

Lily Chu (vicevoorzitter van IACFS-ME en lid van de IOM-commissie die de SEID-criteria aanprijst) e.a.

hebben de symptomen van een groep van 131 CVS-patiŽnten na 6 maanden ziekte in kaart gebracht

en geanalyseerd in hoeverre de patiŽnten aan de SEID-, ME-ICC- en ME/CVS-CCC-criteria voldeden.

 

Het resultaat ziet U hieronder in tabel 2 weergegeven:

 

 

 

De auteurs suggereren, op basis van tabel 5 (hieronder), dat de SEID-, ME-ICC- en CCC-criteria

dezelfde patiŽnten afdekken en dat, gezien de eenvoud, de SEID-criteria de voorkeur verdienen.

 

 

 

 

Tabel 2 en tabel 5 lijken met elkaar in tegenspraak (en zijn dat ook!).

 

Dat wordt duidelijk uit figuur 8 (en figuur 4) van de 'bijlagen' (Supplementary Material):

 

 

 

 

Slechts 50 van de 103 patiŽnten voldoet aan alle vier criteria.

Van de 94 patienten die aan de SEID-criteria voldoen (getallen binnen het gele vak),

voldoen 56 patiŽnten aan de ME-ICC-criteria (getallen binnen het groene en gele vak) en

voldoen 71 patiŽnten aan de ME/CVS-CCC-criteria (getallen binnen het paarse en gele vak).

 

Stellen dat bijna alle mensen die aan de SEID-criteria voldoen ook aan de ME-ICC- en CCC-criteria

voldoen, is slechts de halve 'waarheid' verkondigen: het omgekeerde geldt namelijk niet...

 

 


 

 

Patients diagnosed with Myalgic encephalomyelitis/chronic fatigue syndrome

also fit systemic exertion intolerance disease criteria.

Abstract

 

Background:

 

Myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS)

remains undiagnosed in up to 91% of patients.

 

Recently, the United States-based Institute of Medicine (IOM) developed

new diagnostic criteria, naming it systemic exertion intolerance disease (SEID).

 

 

Purpose:

 

We examined how subjects fit SEID criteria and existing ME/CFS case definitions early in their illness.

 

 

Methods:

 

A total of 131 subjects fitting 1994 Fukuda CFS criteria at the time of study recruitment

completed a survey of symptoms they experienced during their first 6 months of illness.

 

Symptoms were drawn from SEID and existing criteria

(1994 Fukuda, 2003 Canadian Consensus Criteria (CCC), and

2011 Myalgic Encephalomyelitis-International Consensus Criteria (ME-ICC)).

 

We calculated and compared

the number/percentage of subjects

fitting single or combinations of case definitions and

the number/percentage of subjects with SEID

experiencing orthostatic intolerance (OI) and/or cognitive impairment.

 

 

Results:

 

At 6 months of illness,

SEID criteria identified 72% of all subjects,

similar to when Fukuda criteria (79%) or the CCC (71%) were used,

whereas the ME-ICC selected for a significantly lower percentage (61%, p < .001).

 

When severity/frequency thresholds were added to the Fukuda criteria, CCC and ME-ICC,

the percentage of these subjects also fitting SEID criteria increased to 93%, 97%, and 95%.

 

Eighty-seven percent of SEID subjects endorsed cognitive impairment and 92%, OI;

79% experienced both symptoms.

 

 

Conclusions:

 

SEID criteria categorize a similar percentage of subjects as Fukuda criteria

early in the course of ME/CFS and

contain the majority of subjects identified using other criteria while requiring fewer symptoms.

 

The advantage of SEID may be in its ease of use.
