Post-poliomyelitis syndrome as a possible viral disease

Area of Science:

• Neurology
• Infectious Diseases
• Immunology

Background:

• Post-polio syndrome (PPS) is a late-onset neurological condition affecting polio survivors.
• It impacts millions globally, leading to progressive muscle weakness, fatigue, and functional decline.
• Understanding PPS pathogenesis is crucial for managing long-term sequelae of poliomyelitis.

Purpose of the Study:

• To review current knowledge on post-polio syndrome (PPS).
• To explore potential pathogenic mechanisms, including persistent poliovirus infection and chronic inflammation.
• To discuss novel therapeutic strategies and ongoing clinical trials for PPS.

Main Methods:

• Literature review of epidemiological data and pathogenic pathways of PPS.
• Analysis of emerging anti-poliovirus agents and monoclonal antibodies.
• Summary of current clinical trials and treatment approaches for PPS.

Main Results:

• PPS is characterized by new-onset muscle weakness, fatigue, and atrophy in polio survivors.
• Persistent poliovirus infection and chronic inflammation are implicated in the progressive degeneration of motor units.
• Novel antiviral compounds and immunotherapies show promise for PPS treatment and polio eradication.

Conclusions:

• Post-polio syndrome presents a significant challenge for polio survivors, necessitating further research into its mechanisms.
• Emerging antiviral agents and immunotherapies may offer new treatment avenues for PPS.
• Intravenous infusion of normal human immunoglobulins is a promising therapeutic option currently under investigation for PPS.
