Human Immunodeficiency Virus-Associated Progressive Multifocal Leukoencephalopathy: Apparent Response to 3'-Azido-3'-Deoxythymidine

We present the case of a 26-year-old human immunodeficiency virus-seropositive man who developed progressive multifocal leukoencephalopathy as the initial manifestation of AIDS. He appears to have responded dramatically to therapy with 3'-azido-3'-deoxythymidine (AZT). His neurologic status deteriorated shortly after an AZT dose reduction. He has stabilized since resuming his previous AZT dose. Although it remains unclear whether AZT is useful in the treatment of JC virus infection, we think that all AIDS patients with progressive multifocal leukoencephalopathy should be offered treatment with AZT, especially in light of recent reports describing a possible potentiation of human immunodeficiency virus infection of the central nervous system in this setting.

Lack of activity of zidovudine in AIDS-associated Kaposi's sarcoma.

The efficacy of zidovudine (AZT) for treatment of patients with Kaposi's sarcoma as the initial manifestation of AIDS was determined in a non-randomized, phase-II clinical trial. Twenty-two patients were treated with zidovudine (300 mg 4 times daily for 8 weeks). In patients with stable disease or showing a response, treatment was continued. After 12 weeks the total daily dose was changed to 1000 mg. Only two of all 22 evaluable patients achieved a response (one complete and one partial response), of only brief duration (2 and 4 months, respectively). There was no such association between antiretroviral activity, increase in CD4+ cells and tumour response, as was reported during treatment with human recombinant interferon alpha (IFN-alpha). These findings do not support the use of zidovudine as a first-line treatment for patients with AIDS-associated Kaposi's sarcoma.

Acute myeloradiculitis due to cytomegalovirus as the initial manifestation of AIDS.

A 26 year old male intravenous drug abuser presented with rapidly progressive paraplegia and total incontinence. CSF examination showed elevated protein level and pleocytosis. HIV testing was positive. Anti CMV titres were mildly elevated in serum and CSF. Death occurred 26 days after the onset of neurological signs. Necrotic and inflammatory lesions with numerous inclusion bodies characteristic of CMV were found in the roots of the cauda equina, conus terminalis and lumbar segments of the spinal cord. CMV subependymal encephalitis and HIV encephalitis were also present.

Cytomegalovirus Retinitis as the Initial Manifestation of the Acquired Immune Deficiency Syndrome

We studied eight patients in whom cytomegalovirus retinitis was an initial manifestation of AIDS. Six of these patients had cytomegalovirus retinitis alone at the time of diagnosis and two patients had simultaneous cytomegalovirus retinitis with other AIDS associated diseases (Kaposi's sarcoma in one patient and cytomegalovirus colitis in one patient). Treatment with ganciclovir (dihydroxy propoxymethyl guanine), a new antiviral medication related to acyclovir, resulted in regression of retinitis in all five patients treated with this drug. Our study shows that cytomegalovirus retinitis may be the initial manifestation of AIDS and that ganciclovir is a clinically effective antiviral agent for cytomegalovirus.

Initial manifestation of acquired immunodeficiency syndrome in the head and neck region

Initial manifestation of AIDS in the head and neck region occurs frequently. The purpose of this report has been to alert the head and neck surgeon to the occurrence of AIDS-related lesions, their clinical characteristics, and disease outcome. Incomplete recognition of these disorders may delay appropriate diagnostic study and initiation of therapy. We have described 10 patients in whom the initial manifestation of AIDS-related malignancies occurred in the head and neck region. Six of these patients were found to have Kaposi's sarcoma, whereas four had non-Hodgkin's lymphomas. The specific clinical and pathologic aspects of the disease have been described, which represent common patterns of presentation. It is crucial to obtain an accurate social history, as well as a complete medical history from any patient suspected of having AIDS, and prompt biopsy of suspect lesions should be performed.

Bilateral Angle-Closure Glaucoma in Association with the Acquired Immune Deficiency Syndrome

Two homosexual men, 35 and 42 years old, had bilateral acute angle-closure glaucoma in association with the acquired immune deficiency syndrome. In one patient, the angle-closure attack was the initial manifestation of AIDS. Choroidal effusion with secondary anterior rotation of the ciliary body at the scleral spur appeared to be the pathophysiologic mechanism. Pupillary block, angle crowding, and inflammatory synechial angle closure must be differentiated from anterior rotation of the ciliary body as the mechanism of the angle closure to provide optimal treatment. Whereas primary angle closures are treated with miotics and iridectomy, secondary angle closure may be worsened with this treatment. Cycloplegics and, if necessary, drainage of suprachoroidal fluid may be curative in AIDS-related angle closure associated with a choroidal detachment. Both patients died before the long-term efficacy of this treatment could be assessed.
