Ocular myositis as first presenting symptom of human immunodeficiency virus (HIV-1) infection and its response to high-dose cortisone treatment.

A 30-year-old male presented with signs of ocular inflammation and motility disturbances in an early stage of HIV infection. The provisional diagnosis of an ocular myositis was confirmed by orbital echograms. A general check up revealed positive anti-smooth-muscle antibodies and antinuclear antibodies as well as a raised erythrocyte sedimentation rate. Oral steroid treatment in addition to steroid eyedrops achieved complete resolution of clinical and sonographic symptoms within 15 weeks. Autoimmune phenomena are well known presentations of HIV infection. In this case oral cortisone proved to be an effective therapy even in the setting of an HIV infection.

The spectrum of peripheral neuropathy associated with ARC and AIDS.

Peripheral neuropathy is increasingly recognized as a complication of the Acquired Immune Deficiency Syndrome (AIDS) and AIDS-related complex (ARC), but the varied clinical features have been incompletely described. Thirty homosexual men with peripheral neuropathy were evaluated in this study. Twenty-one had ARC and nine had AIDS. Four distinct clinical syndromes were recognized: distal sensorimotor polyneuropathy, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), mononeuropathy multiplex, and progressive polyradiculopathy. Four patients with clinical, electrophysiologic, and histologic evidence of CIDP and severe progressive weakness improved with plasma exchange, three regaining normal function.

Antibody-mediated peripheral neuropathies associated with ARC and AIDS: successful treatment with plasmapheresis.

Peripheral neuropathy is increasingly recognized in patients with AIDS as well as AIDS-related complex (ARC). Thirty homosexual men with polyneuropathy were evaluated in this study. Twenty-one had ARC and nine had AIDS. We observed three distinct clinical syndromes: distal sensorimotor polyneuropathy, chronic inflammatory demyelinating polyrediculoneuropathy (CIDP), and mononeuropathy multiplex. Circulating antibodies to peripheral nerve tissues were found in all patients. In six patients, treatment with plasma exchange was undertaken because of severe, progressive weakness. Four patients with clinical, electrophysiologic, and histologic evidence of CIDP improved with plasma exchange, three regaining normal function. These results suggest that the peripheral neuropathy associated with ARC and AIDS is immunologically mediated and that plasma exchange is an effective treatment in a subgroup of patients with this disorder.

AIDS and apheresis procedures--therapeutic and safety considerations.

The role of therapeutic apheresis was assessed in a number of clinical syndromes associated with the acquired immune deficiency syndrome (AIDS) and AIDS-related complex (ARC). Four groups of patients were studied: AIDS with opportunistic infections, AIDS with Kaposi's sarcoma, AIDS/ARC patients with peripheral neuropathy and a patient with AIDS-related immune thrombocytopenia. Intensive plasmapheresis was shown to have no significant effects on the disease course of patients with full-blown AIDS. However, intensive plasma exchange restored normal neurologic function in the majority of patients with AIDS/ARC-related peripheral neuropathy. Selective immunoadsorption by means of protein A columns led to a sustained normalization of platelet counts in a patient with severe immune thrombocytopenia. A phase I study of AIDS-related Kaposi's sarcoma demonstrated that protein A immunoadsorption was tolerated well and was accompanied by partial responses. Patients being plasmapheresed for conditions other than AIDS were not found to be at any greater risk for acquiring AIDS-related viruses. Finally, health care professionals performing apheresis procedures on AIDS patients were not shown to be at increased risk of contracting AIDS-related viruses provided reasonable blood precautions were exercised.
