Peripheral neuropathy during alpha-interferon therapy in a child with Hodgkin's disease
1Department of Pediatric Oncology, Hacettepe University Faculty of Medicine, Ankara, Turkey.
Abstract:
Peripheral neuropathy is one of the rarely reported neurological complications of interferon therapy. The authors report such a case in a 15-year-old boy during alpha-interferon therapy for Hodgkin's disease. He received alpha-interferon at a dose of 1.8 million units/day 5 times a week by subcutaneous injections as adjuvant immunotherapy post autologous stem cell transplant. Twenty months after the initiation of therapy, he complained of severe pain in his lower distal extremities. Neurological examination revealed the absence of deep tendon reflexes. A nerve conduction study showed a sensorial, polyneuropathic involvement in the lower extremities. Within 4 weeks after the stopping of interferon, his pain improved, and recovery was also seen by nerve conduction studies. Symptoms reappeared at the resumption of interferon treatment. This study suggests that peripheral neuropathy may rarely occur in patients given long-term interferon treatment at high cumulative dosage.
Insights
Peripheral neuropathy is a rare neurological complication of interferon therapy. This case study highlights its occurrence in a young Hodgkin
Area of Science:
- Neurology
- Oncology
- Immunotherapy
Background:
- Peripheral neuropathy is an uncommon neurological complication associated with interferon therapy.
- Alpha-interferon is used in treating certain cancers, including Hodgkin's disease.
- Neurological adverse events require careful monitoring in patients undergoing long-term immunotherapy.
Purpose of the Study:
- To report a rare case of peripheral neuropathy in a pediatric patient receiving alpha-interferon.
- To investigate the relationship between alpha-interferon treatment and the development of neuropathy.
- To assess the reversibility of interferon-induced neuropathy upon treatment cessation.
Main Methods:
- A case report of a 15-year-old boy treated with alpha-interferon for Hodgkin's disease.
- Clinical assessment including neurological examination and nerve conduction studies.
- Observation of symptoms and electrophysiological changes before, during, and after interferon therapy.
Main Results:
- The patient developed severe distal extremity pain and absent deep tendon reflexes 20 months into therapy.
- Nerve conduction studies confirmed sensory polyneuropathic involvement in the lower extremities.
- Symptoms and electrophysiological findings improved after stopping interferon and recurred upon re-initiation.
Conclusions:
- Peripheral neuropathy is a potential, albeit rare, complication of long-term, high-dose interferon therapy.
- Interferon-induced neuropathy appears to be reversible upon discontinuation of the drug.
- This case underscores the importance of vigilance for neurological complications during interferon treatment.
