🔹Cytokine Storm = uncontrolled cytokine release → multiorgan failure → death.
🔹Most important cytokines:
🔹IL-6 ⭐
🔹TNF-α ⭐
🔹IFN-γ ⭐
🔹IL-1 ⭐
🔹IL-18 ⭐
⸻
🔹🔥 Most important clinical features:
🔹Fever
🔹Hepatosplenomegaly
🔹Cytopenia
🔹Coagulopathy
🔹Hyperferritinemia
⸻
🔹🔥 Most important labs:
🔹↑ Ferritin ⭐⭐⭐
🔹↑ D-dimer ⭐⭐⭐
🔹↑ CRP ⭐⭐⭐
🔹↑ IL-6 ⭐⭐⭐
🔹↑ AST/ALT
🔹↑ LDH
🔹↑ Creatinine
⸻
🔹🔥 COVID severe disease markers:
🔹Lymphopenia
🔹Thrombocytopenia
🔹Ferritin ↑
🔹D-dimer ↑
🔹IL-6 ↑
🔹🧨 If examiner asks:
🔹”Best biomarker of severe cytokine storm?”
🔹Think IL-6 + Ferritin
⸻
🔹🔥 Mechanism in one line:
🔹PRR activation
➡ NF-κB
➡ Cytokine release
➡ DIC
➡ Organ failure
➡ Death
⸻
🔹🔥 Bacteria associated with cytokine storm:
🔹Streptococcus pyogenes
🔹Staphylococcus aureus
🔹Francisella tularensis
🔹Klebsiella pneumoniae
🔹Yersinia pestis
⸻
🔹🔥 Viruses associated with cytokine storm:
🔹CMV
🔹EBV
🔹Influenza
🔹SARS-CoV
🔹SARS-CoV-2
🔹H5N1
⸻
🔹🔥 ACE2 receptor found in:
🔹Lung
🔹Heart
🔹Kidney
🔹GI tract
🔹Pancreas
🔹🧨 This explains why COVID can affect many organs.
⸻
🔹🔥 Treatment:
🔹Dexamethasone
🔹Glucocorticoids
🔹Anti-cytokine therapy:
🔹Anti-IL-1β
🔹IL-1 receptor antagonist
🔹Anti-IL-18
🔹IL-6 inhibitors ⭐
⸻
🔹👑 TOP 10 THINGS MOST LIKELY TO APPEAR
🔹1. Hypercytokinemia = Cytokine storm.
🔹2. IL-6 is the star cytokine.
🔹3. Ferritin ↑.
🔹4. D-dimer ↑.
🔹5. Fever.
🔹6. Cytopenia.
🔹7. Coagulopathy.
🔹8. ACE2 receptor.
🔹9. Dexamethasone treatment.
🔹10. DIC → multiorgan failure.
⸻
🔹🧨 EXAM TRAPS
🔹Ferritin is an acute-phase reactant.
🔹LDH elevation = tissue damage.
🔹Delayed Type I interferon response worsens COVID.
🔹Diabetes, hypertension, cardiovascular disease = risk factors.
🔹IL-6 inhibitors are targeted therapy.
⸻
🔹🔪 KILLER MEMORY
🔹**“IL-6 raises Ferritin and D-dimer, causing DIC and multiorgan failure.”**
🔹😈 Corner of stupidity:
🔹If you leave this lecture remembering only one thing, remember:
🔹IL-6 + Ferritin + D-dimer = Cytokine Storm MCQ.
🔹🚨 MCQ ALERT
🔹IL-6 and Ferritin are the most important biomarkers of severe/fatal COVID-19 cytokine storm.
🔹🚨 MCQ ALERT
🔹ACE2 is the entry receptor for SARS-CoV-2.
🔹🚨 MCQ ALERT
🔹DIC is a major cause of multiorgan failure in cytokine storm.
