Poliomyelitis is a viral infection that causes flaccid paralysis in approximately 1% of cases. The Fc receptors for immunoglobulin G (FcgammaR) are associated with modifying effects of several ...infectious and autoimmune diseases. To assess the influence of FcgammaR polymorphisms on the acute and late course of poliomyelitis, 110 Norwegian patients with well-defined histories of acute poliomyelitis were genotyped, of whom 50 suffered from the postpolio syndrome (PPS). In comparison with healthy control subjects without a history of poliomyelitis, significantly fewer patients had the FcgammaRIIIA genotype V/V (P<.01). However, this genotype was not an independent risk factor for PPS. The FcgammaRIIA and IIIB genotypes and allele frequencies did not differ between the patients and control subjects. The FcgammaRIIIA V/V genotype may lower the risk for contracting acute poliomyelitis through better clearance of poliovirus.

Postpolio syndrome is characterised by new muscular weakness, pain, and fatigue several decades after the acute polio, and affects approximately 1/4 of patients with previous paralytic polio.
A ...47-year-old woman with a previous history of acute poliomyelitis developed progressive muscular weakness in her left arm and right leg with muscular pain and fatigue. Clinical examination, MRI, and electromyography gave no other explanation to her progressive muscular weakness and fatigue than postpolio syndrome. She was treated with 400 mg/kg immunoglobulin intravenously for five consecutive days.
At follow-up two and three months later, she had a considerable increase in isokinetic muscle strength in knee extension and flexion on the right side, and experienced less fatigue.
This case suggests that stabilisation of an autoimmune dysfunction may be a therapeutic option in postpolio syndrome.
