MEA stakeholder response to the NICE guideline on the management of Long COVID, which is published today.
It is surprising and disappointing to find that the draft guideline:
(1) Has no recognition that some of the common underlying clusters of symptoms being reported in people with Long/Post COVID are exactly the same as those found in people with a post viral fatigue syndrome (PVFS) or ME/CFS
The key overlapping symptoms include:
cognitive dysfunction/'brain fog’;
dysautonomia – involving orthostatic intolerance,
postural orthostatic tachycardia, postural hypotension;
problems with thermoregulation
unrefreshing sleep patterns and
post exertional malaise/symptom exacerbation.
It would be very surprising if this was not the case given the fact that any type of viral infection can trigger a post viral fatigue syndrome and research carried out following previous coronavirus infections has reported that 10% or more of those infected go on to develop a PVFS or an ME/CFS like illness.
(2) Contains almost no information on the pragmatic management of the symptoms that are being commonly reported – activity and energy management in particular. This is also very surprising when a new draft guidance from NICE on the management of ME/CFS has just been published for stakeholder consultation. This guidance contains detailed recommendations on the sort of energy and activity management that is applicable to people with a post viral fatigue syndrome (regardless of triggering infection) and ME/CFS in both the pre diagnosis and post diagnosis stages.
It should not be left to the charity sector to be providing the sort of detailed self-help management guidance on all these common symptoms that people with Long COVID are reporting.
MEA guidance on post COVID fatigue and Long/Post COVID syndromes
EPIDEMIOLOGY AND DEMOGRAPHICS
Whilst acknowledging that evidence is preliminary and emerging, there should be more information on what we currently know about the epidemiology and demographics of COVID. In particular:
Most cases are being reported in people who self managed at home with a mild or moderate illness
Many are previously fit young adults in their 20s to 50s
Cases being reported in children and adolescents as well
More likely in people who had multiple symptoms at onset of COVID. Possible link to asthma
Current evidence suggests that around 10% of people who develop COVID are developing prolonged symptoms – there could be up to 60,000 people with Long COVID
DIET AND NUTRITION
Why is there no guidance on diet and nutrition, especially strategies that can help to sustain energy requirements throughout the day and encouraging good fluid intake – which can help with orthostatic intolerance. Weight loss should be recorded and advice given where appropriate,
2. ASSESSING PEOPLE WITH NEW OR ON-GOING SYMPTOMS (2.6)
Why is there no list of symptoms that are commonly being reported?
Possibly in the form of two lists that cover symptoms that are common to PVFS and those which may represent end organ damage from COVID-19…
Symptoms consistent with a PVFS:
Debilitating fatigue that is often activity or exercise induced
Dysautonomia – Orthostatic intolerance, PoTS and postural hypotension
Problems with thermoregulation/temperature control
Post exertional malaise/symptom exacerbation
Symptoms that are consistent with possible end organ damage from COVID 19
Shortness of breath
Arrhythmias and palpitations
Abdominal pain and diarrhoea
Loss of taste and smell
2.1 Why is there no mention of possible investigations that could/should be carried out in primary care at this stage?
For example – Would spirometry help in the assessment of lung damage that may be present? And ECG may be appropriate if there are cardiac symptoms.
Autonomic nervous system dysfunction can be assessed using a Composite Autonomic Symptom Scale
3 FURTHER INVESTIGATION AND REFERRAL
Why is there no mention of the new network of Post/Long COVID clinics and how contact details and protocols can be accessed
3.3 Post viral syndromes can precipitate other medical conditions that have remained silent up until now. So clinical judgement needs to be used to assess whether persisting symptoms are simply linked to COVID. For example
Could persisting abdominal pain and diarrhoea be due to an inflammatory bowel disease being precipitated?
Could muscle pain be due to a polymyalgia rheumatica being precipitated – as has been reported?
Could muscle weakness be due to myasthenia gravis? – as reported in the ‘Annals of Internal Medicine'.
3.3 refer to other inflammatory markers in people with persisting bowel symptoms following COVID – ie calprotectin
3.4 The use of exercise testing requires further clarification. Exercise testing does not form part of the clinical assessment of people who have a PVFS or ME/CFS. It may have some value in assessing cardiorespiratory function where this has been affected by the acute infection.. However, is there any evidence to indicate that this is a safe procedure to carry out in people with Long COVID who are experiencing post exertional symptom exacerbation.?
Research evidence indicates that a two day cardiopulmonary exercise test can be helpful in the clinical assessment, diagnosis and monitoring of people with PVFS and ME/CFS. However it can cause an exacerbation of symptoms.
This whole section is inadequate
I can understand why symptoms relating to end organ damage involving heart, lungs etc are being referred to other sources of information on their management
But why is there no basic information on the management of the main post viral symptoms, activity and energy management in particular, that are associated with COVID:
Activity induced fatigue
Post exertional malaise
Especially when guidance on these symptoms is contained in the new (draft) ME/CFS guidance
We are particularly concerned about the emphasis on the use of the terms rehabilitation and goal setting at whatever stage a person is at in their Long COVID journey. There is no reference to the importance of rest, convalescence and pacing physical and mental activities when it becomes apparent that a person is not recovering from a COVID infection after a few weeks. Experience of dealing with people who have PVFS indicates that appropriate advice on activity and energy management during the very early stages (ie weeks) following the triggering infection can have a very beneficial effect on outcome. We are hearing from people with Long/post COVID who have relapsed as a result of returning to exercise too early onor trying to do too much and not keeping within their energy envelope.
Why is there no reference to the warning that NICE issued in July in relation to the use of graded exercise therapy?
As already stated, this guidance could learn a lot from charity and physician experience of dealing with people who have a variety of post infectious fatigue syndromes
In other words >>
The first definition is OK for people who remain symptomatic for up to four weeks.
After four weeks it would be more appropriate to be labelling this as a Long/Post COVID syndrome.
And where symptoms persist for more than three months, and are consistent with diagnostic criteria for ME/CFS, serious consideration should be given as to whether the person does now have Post COVID ME/CFS.
