[[Cytokine storm]] | [[Cytokine storm]]<nowiki/>s are suspected to be the major cause of death in the previous [[influenza]] [[virus]] [[pandemic]] of 1918, [[H5N1]] [[epidemic]] of 1991 and [[SARS]] [[epidemic]] of 2003. A [[cytokine storm]] is an [[immune reaction]] that is characterized by dysregulated and excessive release of pro-[[inflammatory]] [[Cytokine|cytokines]]. [[Cytokine storm|Cytokine storms]] (dysregulated and excessive release of [[Cytokine|cytokines]]) have been associated with [[Acute respiratory distress syndrome|ARDS]] in [[SARS coronavirus|SARS coronavirus (SARS-CoV)]] and [[Middle East respiratory syndrome coronavirus infection causes|MERS coronavirus (MERS-CoV)]] infections. The characteristic of this phenomenon could be considered as an indicator of adverse clinical outcomes such as [[ARDS]], [[shock]], and [[Acute kidney injury|ARF]]. It has been reported that in patients with [[COVID-19]] there is increase in IL-1B, [[Interferon|IFN]]-γ, IP-10, and [[CCL2|monocyte hemoattractant protein 1 (MCP-1)]] and [[COVID-19]] patients in the [[Intensive care unit|intensive care unit (ICU)]] have increased levels of [[granulocyte colony-stimulating factor]], IP-10, [[CCL2|MCP-1]], [[macrophage]] inflammatory protein-1A, and [[Tumor necrosis factor-alpha|TNF-α]] compared to those in general wards. However, in contrast to [[Severe acute respiratory syndrome|SARS infection]], patients with [[COVID-19]] infection have high levels of [[Interleukin 4|IL-4]] and [[Interleukin 10|IL-10]] (secreted by [[Th2|Th2 cells]]), which are [[anti-inflammatory]] [[Cytokine|cytokines]]. Potential therapies suggested for [[cytokine storm]] include: [[Corticosteroids]], [[tocilizumab]], [[etoposide]] and [[ruxolitinib]]. | ||

Overview
Cytokine storms are suspected to be the major cause of death in the previous influenza virus pandemic of 1918, H5N1 epidemic of 1991 and SARS epidemic of 2003. A cytokine storm is an immune reaction that is characterized by dysregulated and excessive release of pro-inflammatory cytokines. Cytokine storms (dysregulated and excessive release of cytokines) have been associated with ARDS in SARS coronavirus (SARS-CoV) and MERS coronavirus (MERS-CoV) infections. The characteristic of this phenomenon could be considered as an indicator of adverse clinical outcomes such as ARDS, shock, and ARF. It has been reported that in patients with COVID-19 there is increase in IL-1B, IFN-γ, IP-10, and monocyte hemoattractant protein 1 (MCP-1) and COVID-19 patients in the intensive care unit (ICU) have increased levels of granulocyte colony-stimulating factor, IP-10, MCP-1, macrophage inflammatory protein-1A, and TNF-α compared to those in general wards. However, in contrast to SARS infection, patients with COVID-19 infection have high levels of IL-4 and IL-10 (secreted by Th2 cells), which are anti-inflammatory cytokines. Potential therapies suggested for cytokine storm include: Corticosteroids, tocilizumab, etoposide and ruxolitinib.
Historical Perspective
- The etiological agent is SARS-CoV-2, named for the similarity of its symptoms to those induced by the severe acute respiratory syndrome, causing coronavirus disease 2019 (COVID-19), is a virus identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China.[1]
- The rapidly increasing number of patients suggest that human-to-human transmission is actively occurring.[2]
- The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020.
- On March 12, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic.
- The term cytokine storm was first used in 1993 by Ferrera et all, to describe the pathophysiology of graft versus host disease (GVHD). [3][4]
- Later, the term was used for pancreatitis, where there is an excessive release of cytokines.
- It has been implicated in a number of infectious as well as non-infectious diseases.
- In the context of infectious diseases, it was first used to describe influenza encephalopathy in 2003. It was also used to describe the pathophysiology of cytomegalovirus, epstein-Barr virus-associated hemophagocytic lymphohistiocytosis, group A streptococcus, influenza virus, variola virus, and severe acute respiratory syndrome coronavirus (SARS-CoV).
- Cytokine storms are believed to cause a disproportionate number of deaths in young individuals. It is suspected to be the major cause of death in previous viral pandemics :[5]
- It is also implicated in other rare viral diseases like variola infection, hantavirus pulmonary syndrome, marburg virus, ebola viruses, lassa and junin viruses, dengue viruses etc. [7]
Classification
- There is no established system for the classification of COVID-19-associated cytokine storm.
Pathophysiology
- A cytokine storm is an immune reaction that is characterized by dysregulated and excessive release of pro-inflammatory cytokines.
Cytokines Involved in Cytokine Storm
- Cytokines are small proteins that are released for cell signaling.
- Cytokines types and their actions include:[8]
- Interferons (INFs)
- Key role in innate immunity
- Regulation of the production of antiviral proteins
- Regulation of the production of antiproliferative proteins
- Interleukins (ILs)
- Regulation of immune cell differentiation and activation
- May be pro- or anti-inflammatory
- Chemokines
- Act as chemo-attractants
- Recruitment of leukocytes
- Colony-stimulating factors
- Induction of hematopoietic progenitor cell proliferation and differentiation
- Tumor necrosis factor (TNF)
- Interferons (INFs)
Pathogenesis of Cytokine Storm
- A cytokine storm is an immune reaction that is characterized by dysregulated and excessive release of pro-inflammatory cytokines.
- During sepsis, cytokine storm may be the cause of tissue or organ injury.[9]
- A cytokine storm causes inflammation, which at the beginning of the disease is local and later spreads around by the systemic circulation. This is followed by the repair and restoration of tissues, organs, and their functions. However, in severe or some inflammations, the repair is with fibrosis which may lead to permanent dysfunction of organs.
- Lung damage caused by pathogens (such as SARS-CoV and influenza virus) may lead to acute lung injury (ALI) or acute respiratory distress syndrome (ARDS).
- Cytokines profiles change over time in patients with sepsis:[8]
- In the early stages of the infection (minutes to hours), cytokines such as TNF and IL-1, and chemokines such as IL-8 and MCP-1 (CCL2) increase.
- Then, an increase in IL-6 is followed.
- Later, IL-10 (anti-inflammatory cytokine) increases.
- Pro-inflammatory cytokines that have a role in ARDS include:[10][11][12][13]
- IL-1β
- IL-6
- IL-8 (CXCL8)
- CCL-2 (MCP-1)
- CCL-3 (Macrophage inflammatory protein-1A)
- CCL-5
- IFN-γ-induced protein10 (IP-10, CXCL10)
- Granulocytemacrophage colony-stimulating factor (GM-CSF)
- Cytokine storms (dysregulated and excessive release of cytokines) have been associated with ARDS in SARS coronavirus (SARS-CoV) and MERS coronavirus (MERS-CoV) infections.[14]
- It has been suggested that the pathogenesis of severe COVID-19 infection may be due to cytokine storm and suppression of Th1 antiviral responses since the following findings have been reported to be associated with severe COVID-19 infection:[15][16]
- It has been reported that in patients with COVID-19 there is increase in IL-1B, IFN-γ , IP-10, and monocyte hemoattractant protein 1 (MCP-1) and COVID-19 patients in the intensive care unit (ICU) have increased levels of granulocyte colony-stimulating factor, IP-10, MCP-1, macrophage inflammatory protein-1A, and TNF-α compared to those in general wards. However, in contrast to SARS infection, patients with COVID-19 infection have high levels of IL-4 and IL-10 (secreted by Th2 cells), which are anti-inflammatory cytokines.[17][15][18][17][16]

Causes
- Coronavirus disease 2019 (COVID-19) is caused by a novel coronavirus called SARS-CoV-2 and is the cause of cytokine storm in COVID-19 infection.
Differentiating COVID-19 cytokine storm from other Diseases
- The most appropriate marker of cytokine storm is an increase in IL-6 level.
- Following is a list of diseases that can cause an increase in IL-6 level and cytokine storm :[19]
Epidemiology and Demographics
- Estimation of an accurate number of severe acute inflammation cases is hard due to the lack of a global system to define the severity of the disease.
- Below is a comparison of different studies on the cytokine level of IL-6 in healthy and severely infected individuals:
Plasma IL-6 concenteration reported in COVID-19 | ||
---|---|---|
Report | Total population(IL-6 level range pg/ml) | Severe infection (IL-6 level range pg/ml) |
Zhou et al[20] | 191 (5-11) | 54 (8-14) |
Wu et al[21] | 123 (6-9) | 84 (6-11) |
Mo et al[22] | 155 (17-96) | 85 (31-165) |
Risk Factors
- There are no established risk factors for COVID-19-associated cytokine storm.
Screening
- There is insufficient evidence to recommend routine screening for COVID-19 related cytokine storm.
Natural History, Complications, and Prognosis
- Cytokine storm has no definition, it denotes a hyperactive immune response characterized by release of interferons, interleukins, TNF, chemokines and several other mediators.
- Since SARS-Cov-1, cytokine elevation was associated with various adverse features.[23][24]
- The characteristic of this phenomena could be considered as an indicator of adverse clinical outcomes such as ARDS, shock and ARF.[25]
- Hyper immunity caused by cytokine storm leading to multi-organ failure in COVID-19 is not fully proved yet, but from previous viral epidemics, it is highly suggested to be considered as a reason to this outcome.

Diagnosis
Diagnostic Study of Choice
The most important cytokines that increase are :[26]
The suggested strategy is to measure the so-called cytokines.
History and Symptoms
- COVID-19 infected individuals who go through more adverse clinical manifestations, such as ARDS and high inflammatory states, are more likely to undergo cytokine elevation.
- For COVID-19 associated history and symptoms click here.
Physical Examination
- For COVID-19 Physical examination click here.
Laboratory Findings
- According to many reviews, Interleukin-6 is the best indicator of the cytokine storm.
- IL-6 concentration has been reported by many studies and is believed to be at a maximal cut of 80 pg/ml in a severe form of the disease.
- Patients with higher levels of IL-6 are at a greater chance of severe disease.[22]
Electrocardiogram
- There are no ECG findings regarding COVID-19-associated Cytokine storm.
X-ray
- COVID-19 associated cytokine storm leads to Acute respiratory distress syndrome(ARDS).
- X-ray Findings related to COVID-19 ARDS are:
- Ground-glass opacification and consolidation
- Early findings on the chest radiograph include normal or diffuse alveolar opacities (consolidation), which are often bilateral and which obscure the pulmonary vascular markings.
- Later, these opacities progress to more extensive consolidation that is diffuse, and they are often asymmetrical.

Treatment
Medical Therapy
- Currently, no proven treatment has been suggested.
- Potential therapies for reducing inflammation are:
- Corticosteroids:[29][30]
- Currently in the U.K. there is an ongoing trial (RECOVERY Trial) that Suggest Systemic low dose Dexamethasone decreases mortality by one third.
- Dexamethasone administered as an oral (liquid or tablets) or intravenous preparation. In pregnancy or breastfeeding women, prednisolone (or intravenous hydrocortisone) should be used.
- The suggested dosage is 6 mg once daily for 10 days
- Azithromycin: [31]
- Azithromycin Have shown anti inflammatory effects against Ebola, respiratory syncytial virus and Influenza H1N1.
- Azithromycin 500mg by mouth (or nasogastric tube) or intravenously once daily for 10 days is recommended.
- Remdesivir:[32][33]
- In a first COVID-19 treatment EMA’s human medicines committee (CHMP) recommended remdesivir for EU authorization in a preliminary report.
- A total of 1063 patients underwent randomization in the remdesivir double-blind, placebo-controlled trial.
- Intravenous remdesivir used in adult hospitalized COVID-19 patients in a double-blind, randomized, placebo-controlled trial.
- Dosage of remdesivir is 200 mg loading dose on day 1, which is followed by 100 mg daily for up to 9 additional days or a placebo for up to 10 days in the random trail.
- Preferred regimen in pediatric population who are weighing 3.5 kg to less than 40kg: Remdesivir injection, 100 mg, lyophilized powder which includes a single loading dose of remdesivir 5 mg/kg on Day 1 followed by remdesivir 2.5 mg/kg once daily from Day 2
- Tocilizumab:[34][35][36][37]
- Tocilizumab is an FDA approved drug used for cytokine release syndrome after chimeric antigen receptor infusion, which cause cytokine release storm.
- It is an IL-6 receptor antibody, which is effective in similar clinical manifestations.
- In some off label studies, it has been shown that tocilizumab can cause improvement in patients.
- intravenous infusion with the dose determined by body weight
- 8 mg/kg (maximum: 800 mg/dose) as a single dose; may repeat dose in 8 to 12 hours if signs/symptoms worsen or do not improve.
- 8 mg/kg (maximum: 800 mg/dose) every 12 hours for 2 doses.
- 8 mg/kg as a single dose.
- 4 to 8 mg/kg (usual dose: 400 mg/dose; maximum: 800 mg/dose) as a single dose; may repeat dose in ≥12 hours in patients who remain febrile within 24 hours of initial dose.
- Etoposide:[38]
- Etoposide is used for suppressing cytokine release in hemophagocytic lymphohistiocytosis.
- In patients with severe disease, etoposide can inhibit overwhelming inflammation.
- the suggested dosage is Etoposide 150 mg/m2 daily days 1 and 4
- Ruxolitinib:[39]
- Jack1/2 inhibitor.
- It is used in hemophagocytic lymphohistiocytosis.
- In a prospective randomized trial, it was shown that it reduces the levels of seven cytokines compared to the control group, and resulted in faster improvement in patients with severe infection.
- the suggested dose is 5 mg twice daily.[40]
- Lopinavir-Ritonavir:[41]
- Corticosteroids:[29][30]
Surgery
- Surgical intervention is not recommended for the management of COVID-19-associated cytokine storm.
Primary Prevention
- Since there is no vaccine for COVID-19 there are plenty of primary prevention suggested from CDC such as:[42]
- Hand washing every 10 minutes.
- Using alcoholic hand sanitizer.
- Self quarantine for two weeks if symptomatic.
