Polio Patients in Northern Italy, a 50 Year Follow-up

Area of Science:

• Neurology
• Public Health
• Rehabilitation Medicine

Background:

• Poliomyelitis was a significant public health concern before widespread immunization.
• Polio survivors (PP) often experience long-term sequelae, including post-polio syndrome (PPS).
• PPS is characterized by progressive muscle weakness, pain, and fatigue years after the acute infection.

Purpose of the Study:

• To assess the medical status of polio survivors 50 years post-acute poliomyelitis.
• To compare the degree of paresis between historical (1952-1961) and current (2012) patient cohorts.
• To determine the prevalence of post-polio syndrome (PPS) among polio survivors.

Main Methods:

• Study conducted in Italy involving polio prior patients (PP) who underwent rehabilitation.
• Neurological examinations and telephone interviews assessing pain, paresis, fatigue, and mobility aids were performed in 2012.
• Patients were categorized based on fulfillment of post-polio syndrome (PPS) criteria.

Main Results:

• Of 67 patients studied, 78% were ambulatory, with half of those meeting PPS criteria using wheelchairs.
• Pain was prevalent, affecting eight out of ten individuals.
• Four out of ten polio survivors met the criteria for post-polio syndrome (PPS), with pain being slightly more common in this group.

Conclusions:

• Female gender, fatigue, and wheelchair dependency were significantly associated with post-polio syndrome (PPS).
• Pain was a common symptom in both polio survivors with and without PPS.
• The study underscores the persistent and significant long-term health burden of poliomyelitis.
