For patients with severe long-COVID disability (unable to work, high disease burden) and failed conventional rehabilitation or immunomodulatory trials, investigational stem-cell treatment may offer acceptable risk-benefit, particularly if clinic cost is subsidised through trial sponsorship. For mild-to-moderate long COVID, conventional approaches (pacing, graded exercise physiology, sleep/autonomic support) remain first-line. Decisions should incorporate trial protocol quality, centre expertise, and realistic expectations of partial rather than complete recovery.
Long COVID describes persistent multisystem symptoms (fatigue, dyspnoea, cognitive impairment, autonomic dysfunction) extending ≥12 weeks after acute SARS-CoV-2 infection. Proposed mechanisms include persistent viral fragments in reservoir tissues, endothelial activation with microclot formation, dysregulated immune memory (skewed Th1/Th17 responses, reduced regulatory T cells), and mitochondrial dysfunction. Placental mesenchymal stem cells and exosomes address these pathways through endothelial repair, anti-inflammatory cytokine secretion, and metabolic rescue of dysfunctional immune cells. Eleven registered clinical trials and two actively recruiting protocols evaluate MSC and exosome infusions in long-COVID cohorts, predominantly focusing on severe functional impairment or cardiopulmonary involvement.
