Long COVID, a prolonged illness after COVID-19, may persist for months after the acute infection and affects at least 65 million individuals worldwide. A puzzling feature of long COVID is that initial disease severity is not an accurate predictor; long COVID frequently occurs in people who had mild-to-moderate COVID cases as well as in younger adults who did not require respiratory support or intensive care. Patients with long COVID should be managed by clinicians who have experience treating this troublesome disorder. Early treatment is essential; the response to treatment will likely be attenuated when treatment is delayed.
Many patients experience prolonged illness after COVID-19. This is commonly known as ‘long COVID’, though it also referred to as ‘Long Haul COVID Syndrome (LHCS)’ or ‘Post-acute sequelae of COVID-19 (PASC)’.
Long COVID may persist for months after the acute infection and almost half of patients report reduced quality of life. At least 65 million individuals worldwide are estimated to have long COVID.
A puzzling feature of long COVID is that initial disease severity is not an accurate predictor; long COVID frequently occurs in people who had mild-to-moderate COVID cases as well as in younger adults who did not require respiratory support or intensive care.
What are the Symptoms of Long COVID?
Many of the symptoms of long COVID are common to COVID-19 vaccine injury (also known as long vax); indeed, both disorders are considered manifestations of “spike protein-related disease” with a significant overlap in symptoms, pathogenesis, and treatment.
The major difference between long COVID and long vax is unresolved organizing pneumonia with persistent respiratory symptoms. Clinicians have also noted that long-vax patients tend to have more severe illness due to a higher incidence and severity of neuropathic symptoms and dysautonomia.
Long COVID and long vax are heterogeneous syndromes, meaning their symptoms and clinical features vary widely in presentation, severity, and underlying causes or contributing factors. Both are characterized by prolonged malaise, headaches, generalized fatigue, sleep difficulties, hair loss, smell disorder, decreased appetite, painful joints, dyspnea, chest pain, and cognitive dysfunction. Patients may suffer prolonged neuropsychological symptoms, including multiple domains of cognition.
The symptom set of long COVID is, in the majority of cases, very similar to chronic inflammatory response syndrome (CIRS)/myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). An important differentiating factor from CIRS is the observation that long COVID continues to improve on its own, albeit slowly in most cases. Another important observation is that long COVID includes more young people compared to severe COVID, which affects older people or persons with comorbidities. Furthermore, the similarity between mast cell activation syndrome (MCAS) and long COVID has been observed, and many consider long COVID to be a variant of MCAS.
Groups of Symptoms
The clinical signs and symptoms can be grouped into the following clusters. The reason for this grouping is to allow organ-specific targeted therapy or individualized therapy:
- Respiratory: shortness of breath, congestion, persistent cough, etc.
- Neurological/psychiatric: brain fog, malaise, tiredness, headaches, migraines, depression, inability to focus or concentrate, altered cognition, insomnia, vertigo, panic attacks, tinnitus, anosmia, phantom smells, etc.
- Musculoskeletal: myalgias, fatigue, weakness, joint pains, inability to exercise, post-exertional malaise, inability to perform normal activities of daily life
- Cardiovascular: Palpitations, arrhythmias, Raynaud-like syndrome, hypotension, and tachycardia on exertion
- Autonomic: Postural tachycardia syndrome (POTs), abnormal sweating
- Gastrointestinal disturbance: anorexia, diarrhea, bloating, vomiting, nausea, etc.
- Dermatologic: itching, rashes, dermatographia
- Mucus membranes: running nose, sneezing, burning and itchy eyes
The following basic tests are recommended — tests such as cytokines and chemokines, autoantibodies, and toxicological studies are expensive, have very little clinical relevance, and only complicate the management of long COVID patients.
- CBC with lymphocyte count and CD8+ count
- Chemistry with liver function tests
- CRP (inflammation)
- Ferritin (macrophage activation)
- Early morning cortisol
- Thyroid function tests
- HbA1C—long COVID patients are at an increased risk of developing diabetes
- Autoantibodies: antiphospholipid antibody and ANA
- In patients with allergic features or those who experienced an acute reaction to the vaccine, the following tests may be helpful: eosinophil count; IgE levels, RAST testing and/or skin testing. Serum tryptase, serum histamine and/or 24-h urine N- methylhistamine should be considered in MCAS.
- Reactivated viruses: Antibodies/PCR against EBV Herpes I/II and CMV
- Vitamin D level
Specific Phenotypic tests
- CXR / chest CT with contrast
- Brain MRI
General Approach to Treatment
Patients with long COVID should be managed by clinicians who have experience treating this troublesome disorder. The treatment approach should be individualized according to the grouping of clinical signs and symptoms.
However, in general, it is likely that patients who did not receive adequate antiviral treatment (e.g., ivermectin, etc.) and adequate anti-inflammatory/macrophage repolarization treatment during the acute symptomatic phase of COVID-19 are more likely to develop long COVID.
The core problem in long COVID is chronic “immune dysregulation.” The primary treatment goal is to help the body to restore and normalize the immune system — in other words, to let the body heal itself. We recommend the use of immune-modulating agents and interventions to dampen and normalize the immune system rather than the use of immunosuppressant drugs, which may make the condition worse. However, the concomitant use of a controlled course of an immunosuppressant drug may be appropriate in patients with specific autoimmune conditions.
In addition to treating organizing pneumonia, as noted below, our suggested treatment strategy involves two major approaches i) promote autophagy to help rid the cell of the spike protein and ii) interventions that limit the toxicity/pathogenicity of the spike protein.
Early treatment is essential; the response to treatment will likely be attenuated when treatment is delayed.
Patients should be started on the primary treatment protocol; this should, however, be individualized according to the patient’s particular clinical features. The response to the primary treatment protocol should dictate the addition or subtraction of additional therapeutic interventions. Second-line therapies should be started in those who have responded poorly to the core therapies and in patients with severe incapacitating disease.
NOTE: Patients with long COVID must not receive further COVID-19 vaccines of any type.
Treating Organizing Pneumonia
As noted previously, the major difference between long COVID and long vax is unresolved organizing pneumonia with persistent respiratory symptoms. Therefore, in patients with ongoing respiratory symptoms, chest imaging is suggested (preferably a chest CT scan).
Those with unresolved pulmonary inflammation (organizing pneumonia with ground glass opacification) should be treated with a course of corticosteroids. Low-dose prednisolone/methylprednisolone (10 mg/day) for six weeks is suggested. However, the patient’s symptoms and CRP should be followed closely, as a dose escalation may be required in those who respond poorly.
An unknown number of patients who have recovered from COVID-19 organizing pneumonia will develop pulmonary fibrosis with associated limitation of activity. Pulmonary function testing demonstrates a restrictive type pattern with decreased residual volume and DLCO. These patients should be referred to a pulmonologist with expertise in pulmonary fibrosis. Anti-fibrotic therapy may have a role in these patients, however additional data is required before this therapy can be more generally recommended. The serotonin receptor blocker cyproheptadine may reduce the risk of pulmonary fibrosis.
- Hyperbaric oxygen therapy
- Low Magnitude Mechanical Stimulation
- “Mitochondrial energy optimizer”
- Low dose corticosteroid
A note about anesthesia and surgery:
Patients should notify their anesthesia team if using the following medications and/or nutraceuticals, as they can increase the risk of Serotonin syndrome with opioid administration:
- Methylene blue
- Nigella Sativa
- Selective Serotonin Reuptake Inhibitors (SSRIs)
