Upper and lower chronic respiratory tract infections in patients with retinitis pigmentosa (RP)

Teresa Oleniacz¹, Hanna Dmeńska²

Summary
Retinitis pigmentosa (RP) is a term for a heterogeneous group of hereditary retinal disorders characterised by progressive night blindness, loss of peripheral visual field and often by complete functional blindness by 40 to 50 years of age. Photoreceptor ultrastuctural studies of retinas in RP patients suggest that a defect of the connecting cilium of rods and cones could lead to the degeneration of these cells. It has been suggested that in RP patients motile cilia are also structurally defective. In this paper the cases of three brothers with X chromosome-linked RP and chronic upper and lower respiratory tract infections due to motile cilia structure disorders are presented.
