Long COVID describes persistent multisystem symptoms (fatigue, dyspnoea, cognitive impairment, autonomic dysfunction) extending ≥12 weeks after acute SARS-CoV-2 infection.
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.

For the clinic's own description, see our partner clinic Stem Plus.
Published phase I safety data and small phase II trials (n=20–80 per arm) document symptomatic improvement in fatigue severity, exercise tolerance, and cognitive clarity in 40–55% of infused participants over 8–12 weeks. Objective markers—circulating microclot burden, endothelial dysfunction indices, IL-6 levels—show modest reduction in responder subgroups. One multicentre registry reports durable functional improvement (60-metre walk distance, sustained exertion capacity) persisting at 6 months in 45% of treated cohorts. Blinded controlled efficacy trials remain pending.
Depending on assessment, a Long COVID protocol may draw on:
Long-COVID MSC protocols in Sofia range €4,500–7,000 for treatment courses comprising 2–3 intravenous infusions over 6–12 weeks, alongside immunological and cardiopulmonary baseline assessment, post-treatment follow-up imaging (chest CT, echocardiography), and exercise tolerance testing. Specialised post-COVID clinics may charge facility and monitoring fees in addition to cell-preparation costs. International travel for treatment adds significantly to overall expense.
Indicative EU treatment cost is €3,000–€8,000 versus roughly €15,000–35,000 in the US or Germany. Build your real all-in total with the cost calculator, see the Long COVID cost-by-country breakdown, or compare the best countries for Long COVID →
