Recovery from sensorineural deafness in Wegener's granulomatosis

Wegener's granulomatosis may present with deafness or other aural symptoms. This report describes two patients with histological evidence of Wegener's granulomatosis who developed reversible sensorineural hearing loss during the course of their illness. The first patient showed complete recovery of a sensorineural hearing loss averaging 50 dB after ten months treatment with cyclophosphamide and high-dose prednisolone. The second patient, who was on maintenance haemodialysis, achieved a 40 dB improvement in sensorineural hearing loss within two weeks of adding cyclophosphamide to pre-existing corticosteroid therapy. These findings suggest that the prognosis of sensorineural hearing loss in Wegener's granulomatosis can be improved with suppression of the vasculitic process by early treatment with combined cytotoxic-immunosuppressive therapy.

Ocular involvement in the respiratory vasculitides

The respiratory vasculitides are idiopathic inflammatory syndromes, characteristically involving the pulmonary vasculature as well as that of several other organ systems. The inflammatory response in these diseases is uniformly granulomatous. There are three distinct, recognized respiratory vasculitides: Wegener's granulomatosis, Churg-Strauss syndrome (allergic granulomatosis and angiitis), and lymphomatoid granulomatosis. Each of these entities may have ophthalmic manifestations, and ocular involvement may, in fact, be the presenting sign. The systemic and ocular manifestations, as well as the differential diagnosis and management of each of these entities are discussed.

The treatment of Wegener's granulomatosis with immunosuppressive-cytotoxic drugs

Previous reports of 18 patients with Wegener's Granulomatosis treated with immunosuppressive and cytotoxic drugs are reviewed, and 4 new cases are reported. The prognosis in these patients is shown to be significantly better than that found in previous series where such drugs were not used
