Inpatient and community-based care can be complementary in relation to the management of HIV disease. Medical records from 200 inpatients of Chikankata Hospital near Lusaka, Zambia and 200 home based patients were examined and compared for the common symptoms of presentation of HIV disease, associated opportunistic infections, and treatment protocols. Drug costs of both groups were also compared. The most common respiratory symptoms in the 2 groups are cough, chest pains, weight loss, and hemoptysis. Treatment employed for these symptoms were cortimoxazole, penicillin V, erthromycin, and tetracycline. Acetyl saliclic acid and paracetamol were used for pain relief in both groups. Gastointestinal system symptoms for both groups were diarrhea, weight loss, abdominal pain, and vomiting. Cotrimoxazole and metronidazole were used in treating diarrhea. Additional treatment protocol for the 2 patient samples included oral rehydration therapy for dehydration, antacid or bismuth subsalicylate for diarrhea and enteritis, and mycostatin for oral candidiasis. Central nervous system symptomatology included headache, dementia, neckace, and lethargy. Chloramphenicol was employed in treating bacterial meningitis. Diazepam and chlorpromazine were effective for restless patients. Genito-urinary system symptomatology for the 2 groups included dysuria, genital ulcers, hematuria, viral warts, and buboes. Antibodies were used for sexually transmitted diseases and infections. Skin symptomatology included rash and dermatitis, herpes zoster, abscess, kaposi's sarcoma, ulcers, furunculosis, and discharging anal sinus. In treating these symptoms, hospital based care and home based care were similar. Overall, it was found that hospital treatment protocols were detailed, expensive, and time consuming. Furthermore, hospital treatment for HIV positive patients is more expensive than HIV negative patients; hospital costs for 50 HIV negative patients totaled US$415.94 compared to US$1204.98 HIV positive/PTB negative patients and US$1705.62 for HIV positive/PTB positive patients. Drug cost/patient admission is increased by 469% if HIV positive. (author's modified).

Neopterin and beta 2-microglobulin (beta 2-M) concentrations in cerebrospinal fluid (CSF) and blood were measured in 56 individuals in various stages of HIV-1 infection. Elevated levels of neopterin as well as beta 2-M were found in the CSF of three patients with primary HIV-1 infection and also in subjects in the early stages of chronic HIV-1 infection, with the highest levels in HIV-1 isolation-positive people. There was a clear correlation between the concentrations of the two substances and the levels seemed to increase in parallel with progress of infection. A similar pattern was found in blood. Higher concentrations of neopterin and beta 2-M in CSF than in blood were found in patients with advanced dementia in particular. These findings indicate that the cellular immune system in the central nervous system (CNS) may be activated during the early stages of HIV-1 infection without concomitant overt neurological symptoms. The pathological processes in CNS and blood seem to develop in parallel rather than being restricted to one compartment.

HIV-central nervous system manifestations, here the AIDS-Dementia complex, are at the moment of special interest owing to its unexpected development. With EEG-topography one can expect to gain more information about possible changes in frequency according to topographical location. We recorded 69 HIV-positive hemophiliacs (23 WR 2, 26 WR 3-5 and 6 patients) plus 50 HIV-seronegative controls with a 12 channel EEG-topography evaluation. During the critical examination we looked for the results of two parameters: a) alpha 1-3/alpha 4 and b) alpha 4-4/9. In comparison to the control group we found a statistical significance (p less than 0.05) for WR 2-6 in alpha 1-3/alpha 4 index. Concerning the alpha 1-4/9 index one can only recognize a statistical significance (p less than 0.05) for WR 3-6 patients in comparison to the controls.

There are five known human retroviruses: human T-lymphotropic virus-I (HTLV-I), HTLV-II, HTLV-V, human immunodeficiency virus-1 (HIV-1), and HIV-2. These are related to animal lentiviruses. The simian retroviruses, simian T-lymphotropic virus-I (STLV-I) and STLV-III are related closely to HTLV-I and HIV-2 respectively. HTLV-I and HTLV-II and, possibly, HTLV-V are transforming agents that immortalize the CD4 cell. In contrast, HIV-1 and HIV-2 cause this cell to lyse, resulting in immunodeficiency (ID). HIV-1 and HIV-2 cause severe ID resulting in acquired immunodeficiency syndrome (AIDS). In HTLV-I and HTLV-II, ID is less severe and rarely progressive. Both of these retroviruses induce proliferation of CD4 cells. In HTLV-I, this results in acute T cell leukemia and mycosis fungoides (MF) with hypercalcemia. HTLV-V produces a less severe form of MF without hypercalcemia. Associated lymphomas (AL) occur with HTLV-I. HIV-1 and HIV-2 produce AL as well as Kaposi's sarcoma. Both also cause subcortical dementia because they are neurotropic. All human retroviruses appear to be transmitted sexually and by blood. Transfusional AIDS may be almost entirely eliminated by serologic testing of the blood supply, and transfusional lymphoma can be almost entirely eliminated by universal testing for HTLV-I.

The number of AIDS cases in individuals 50 years of age or older in the United States is reported to exceed 9000. Contaminated blood and blood transfusions are major contributors to HIV-1 infection in this age group. Sexual transmission and infection through intravenous drug abuse are also potential avenues of HIV-1 transmission in the older population. AIDS presents with a variety of clinical manifestations, including dementia, frequently seen in non-HIV-1-infected older people. Neurological deficiencies associated with AIDS are very common and may lead to misdiagnosis in the elderly. The observed incubation period of HIV-1 infection is longer than previously estimated, increasing the risk of older individuals exposed to HIV-1 in the past to develop AIDS. Oral manifestations may present as one of the early clinical signs of AIDS. Little is known concerning AIDS in the geriatric population. It demands consideration by dental professionals treating older individuals belonging to one of the exposure categories of the disease.

The acquired immunodeficiency syndrome (AIDS) dementia complex is a frequent and devastating complication of infection with human immunodeficiency virus-type 1 (HIV-1). Features of the AIDS dementia complex include decreased memory, the inability to concentrate, apathy, and psychomotor retardation. Typical neuropathologic findings include gliosis, focal necrosis of neurons, perivascular inflammation, formation of microglial nodules, multinucleated giant cells, and demyelination. That HIV-1 is the direct cause of this neurologic syndrome is strongly supported by the available evidence. In addition, several studies have identified the monocyte-macrophage as the predominant cell type in the brain infected with HIV-1. However, the mechanisms by which the infected monocytes-macrophages mediate neurologic dysfunction and destruction have not been elucidated.

The neurological complications associated with infection by the AIDS virus, HIV, occurs at an early stage of the disease and often indicate a poor prognosis. A dementia, known as AIDS Dementia Complex, is the most common feature observed, and is found in a majority of patients. The effects of gp120, the external protein envelope of HIV, on cerebral glucose utilization were studied in rats. Intracerebroventricular injection of gp120 significantly reduced glucose utilization in the lateral habenula and the suprachiasmatic nucleus, two regions rich in receptors for Vasoactive Intestinal Peptide (VIP) and the whole brain metabolism showed a significant decrease. The findings suggest that gp120 may alter neuronal function, thereby contributing to sequelae of HIV infection of the brain, and that attachment of HIV particles may involve, for a part, VIP receptors.

The use of MRI in clinical psychiatry is evaluated on the basis of over four years' experience. Of 931 psychiatric patients examined, 156 were found to manifest pathological cerebral conditions, a frequency of 17 per cent, as compared with 2 per cent (2/101) among apparently healthy controls. The occurrence of intracerebral lesions, with exclusively psychiatric symptoms, is illustrated with case reports. The importance is stressed of early examination with neurodiagnostic imaging techniques in cases of psychiatric disorders where any of the following symptoms or preliminary diagnoses are present: atypical psychiatric features, first episode psychosis, late onset depression, dementia, HIV and other infections in conjunction with psychiatric symptoms, hysteria, and alcohol or drug abuse. The findings suggest MRI to be a useful supplementary diagnostic tool for improving the care of the psychiatric patient, while relieving the burden both on the patient's family and on mental health care resources.

Nine of 122 patients dead from AIDS in central London presented with neurological disease, confirmed pathologically in seven. Seven had no other major systemic manifestations. AIDS needs to be considered in the differential diagnosis of meningitis, dementia, diffuse and focal encephalopathies, brainstem syndromes, myelopathy, visual failure and peripheral nerve syndromes. As AIDS becomes more widespread there will be an increasing need for diagnostic HIV testing in many neurological syndromes.

A psychiatric consultation was requested in 51 in-patient cases of HIV infection. Reasons for referral included counselling, the evaluation of depressive symptoms, and the treatment of delirium. The most common DSM-III diagnoses included: delirium (n = 13), major depressive disorders (n = 12), dementia (n = 5), and adjustment disorders with depressive or anxious mood (n = 5). The psychiatric treatment of patients with HIV infection does not differ fundamentally from that of other medically ill patients with similar psychiatric symptoms. However, the psychiatric treatment of patients with HIV infection can be hampered by the fear of contagion, negative attitudes towards homosexuals and drug users, and over-identification or avoidance reactions.
