Unraveling the Multi Organ Impact of SARS-CoV-2 What the Latest Research Reveals

Introduction

The Devastating Reach of SARS-CoV-2 Across the Human Body

Heart and Circulatory System

  • Causes myocarditis, heart failure, and arrhythmias.
  • Triggers thromboembolic events like stroke and myocardial infarction via ACE2 pathways.

Brain and Nervous System

  • SARS-CoV-2 crosses the blood-brain barrier, leading to encephalitis, seizures, and even post-COVID neurodegeneration.
  • Mental health complications include PTSD, depression, and anxiety post-ICU.

Endocrine Glands and Hormonal Disruption

  • Impacts the thyroid, adrenal, pituitary, and parathyroid glands.
  • Causes hormonal imbalances such as decreased GH, TSH, and testosterone.

Digestive Tract and Liver

  • Damages the gastrointestinal lining and impairs liver function.
  • Symptoms range from nausea and diarrhea to acute pancreatitis.

Lungs and Respiratory Tract

  • COVID-19-induced ARDS can leave lasting lung fibrosis.
  • Pulmonary function often remains impaired long after recovery.

Kidneys and Renal System

  • Acute Kidney Injury (AKI) is increasingly observed in hospitalized patients.
  • Conditions like proteinuria and hematuria are common, especially in transplant recipients.

Eyes and Ears

  • Ocular manifestations include conjunctivitis and uveitis.
  • Hearing difficulties may worsen due to pandemic-related isolation and healthcare access issues.

Spleen and Immune Organs

  • Direct viral attack leads to lymphoid depletion and splenic damage.
  • Reduces the immune system’s ability to fight off secondary infections.

A Closer Look at Broader Implications

The American Academy of Neurology emphasizes the need to consider COVID-19’s neuroinvasive potential as part of post-pandemic care planning. Understanding these systemic effects is crucial for holistic treatment and rehabilitation of COVID-19 survivors.
