Chronic Fatigue Syndrome (CFS) and Immunotherapy: Emerging Treatment Directions
May 9, 2025
Chronic Fatigue Syndrome (CFS), also known as Myalgic Encephalomyelitis (ME), is a complex and debilitating condition characterized by profound fatigue, cognitive dysfunction, and a range of other symptoms. Recent research has highlighted the role of immune system dysregulation in CFS, opening avenues for immunotherapy-based interventions.PMC
Understanding Immune Dysfunction in CFS
Harch Hyperbaric Oxygen Therapy
In a subset of CFS patients, the immune system exhibits chronic activation, potentially due to persistent infections or autoimmune responses. Key immune components affected include:
-
T Cells: Reduced proliferative capacity and impaired function.
-
Natural Killer (NK) Cells: Decreased cytotoxic activity, compromising the body’s ability to combat infected or malignant cells.
Moreover, there’s a notable shift from Th1-type (cell-mediated) to Th2-type (humoral) immune responses in CFS patients, leading to an imbalance that may exacerbate symptoms.
Exploring Immunotherapeutic Approaches
Several immunotherapy strategies are under investigation to address the immune imbalances observed in CFS:
1. Autologous Cell Therapy
A Phase I clinical trial conducted at the University of Miami explored the reinfusion of autologous lymph node cells cultured ex vivo to promote a Th2-to-Th1 cytokine shift. Preliminary results indicated cognitive improvements in a majority of participants.
2. Immunomodulatory Agents

Sizofiran: An immunostimulant derived from the Schizophyllum commune mushroom, currently in Phase II trials for CFS treatment.
-
Ampligen (Rintatolimod): An experimental antiviral and immunomodulatory drug showing promise in modulating immune responses in CFS patients.Harch Hyperbaric Oxygen Therapy
3. Intravenous Immunoglobulin (IVIG)
IVIG therapy has been explored in clinical settings, with some studies reporting symptomatic relief in CFS patients. However, results are mixed, and further research is needed to establish efficacy.
The Role of Hyperbaric Oxygen Therapy (HBOT)
Hyperbaric Oxygen Therapy (HBOT) involves breathing pure oxygen in a pressurized environment, which may enhance oxygen delivery to tissues and modulate immune responses. While not a standard treatment for CFS, some studies suggest potential benefits, warranting further investigation.Wikipedia
Conclusion
Immunotherapy represents a promising frontier in the management of Chronic Fatigue Syndrome. Ongoing research into immune-based treatments, including autologous cell therapy, immunomodulatory agents, and HBOT, offers hope for improved patient outcomes. As the scientific community continues to unravel the complexities of CFS, these emerging therapies may pave the way for more effective interventions.
