This study was aimed at investigation of immune status in patients wit
h hemophilic arthropathies and design of optimal therapeutic programs
for them. 103 hemophiliacs were examined. Of them 56 patients had chro
nic productive synovitis and 47 osteoarthrosis. All the patients displ
ayed higher levels of CIC and immunoglobulins than normal subjects, th
e highest values being registered in synovitis. Synovial fluid in them
contained CIC and IgG, IgA, IgM. The findings suggest that immune dis
orders are actively involved in pathogenesis of hemophilic arthropathi
es. Programs of immunocorrecting therapy of synovitides and osteoarthr
oses including plasmapheresis and intraarticular administration of hor
monal and cytostatic drugs produced a clinical response in 80% of the
cases. The remission lasted up to 1 year.
