AIDS oncology

New diagnostic approaches to primary central nervous system lymphoma have been developed that may make brain biopsy unnecessary in many instances. Reduced-dose chemotherapy for non-Hodgkin's lymphoma has been shown to be advantageous in a randomized controlled trial. New agents for the treatment of Kaposi's sarcoma are available. Adoptive cellular immunotherapy has been shown to be effective in the treatment and prevention of Epstein-Barr virus-associated B-cell lymphomas in bone marrow transplant recipients, and may have promise in AIDS patients.     

AIDS dementia

For the geriatrician who commonly evaluates cognitive and psychiatric disorders in the elderly, the neurologic consequences of infection with the human immunodeficiency virus (HIV) are of particular importance. The most frequent neurologic disease is the AIDS dementia complex characterized by cognitive, behavioral, and motor changes, occurring in two-thirds of AIDS patients. The pathophysiology of central nervous system HIV infection has been advanced with important implications for both the diagnosis and the potential treatment of this devastating disease.

AIDS oncology

Kaposi's sarcoma, non-Hodgkin's lymphoma, Hodgkin's disease, and squamous cell carcinoma are among the malignancies seen with increased frequency in patients infected with HIV. The outlook for patients with these malignancies has improved significantly with the utilization of highly active antiretroviral therapy (HAART) and more aggressive cytotoxic therapies. Novel biologic therapies with lesser side effects are currently being evaluated. This article reviews the current knowledge about HIV malignancies, their epidemiology, pathogenesis, clinical manifestations, and treatment.     

AIDS cholangiopathy

Opinion statement AIDS is an advanced disease with systemic and infectious complications that can be fatal. When a patient with AIDS presents with right upper quadrant or midepigastric pain, cholestasis, and symptoms of cholangitis, AIDS cholangiopathy should be suspected and appropriate diagnostic and therapeutic interventions should be initiated. Opportunistic infections such as Cryptosporidium and cytomegalovirus are the most common cause of AIDS cholangiopathy. Four distinct cholangiographic abnormalities have been demonstrated by endoscopic retrograde cholangiopancreatography, the most common being papillary stenosis with sclerosing cholangitis. Antimicrobial therapy is often ineffective. Highly active antiretroviral therapy may enhance immune function and offers the best medical therapy to clear the opportunistic infections. Ursodeoxycholic acid has a limited benefit in patients with sclerosing cholangitis and cholestasis. Endoscopic sphincterotomy has been shown to relieve pain and biliary obstruction in patients with papillary stenosis. Balloon dilation of strictures and stent placement decompress the biliary system and may be helpful. Cholecystectomy is recommended to treat acalculous cholecystitis, and celiac plexus block may be offered to patients with terminal disease and intractable abdominal pain.     

AIDS vasculopathy

Persons infected with HIV display a variety of vascular abnormalities and harbor particularly striking alterations in endothelial morphology and function. We review the effects of the virus and viral products on the endothelium and emphasize their effects on altering the clinical expression of HIV-associated diseases.
