We report 2 patients with AIDS who developed Chagas infection, one with encephalitis, the other with acute myocarditis. The implications of immune depression for the manifestations and course of Chagas disease are discussed. Chagas disease should be considered in patients with AIDS who live in endemic zones and who develop cerebral or cardiac manifestations.

Using a case-control study of untreated men, we investigated the physical, mental, and economic effects of human immunodeficiency virus (HIV-1) infection prior to the diagnosis of acquired immunodeficiency syndrome (AIDS). Beginning 2 to 2.5 years prior to AIDS, case subjects reported more of 12 HIV-1 related symptoms and during the year prior to AIDS, at least 30.6 extra days of these symptoms than did control subjects. Within the 6 months preceding AIDS, case subjects' unemployment rose to 9% (P < or = .05) and depression to 34.2% (P < or = .001). At 6 to 12 months and within 6 months before AIDS, 17.1% and 31.5%, respectively, were anemic, while 37.7% and 64.7% had CD4+ counts less than 200 x 10(6)/L. Diagnosing AIDS at CD4+ counts less than 200 x 10(6)/L could significantly reduce pre-AIDS morbidity. Other implications of these findings are discussed.

HTLV-I (Human T-cell leukemia virus type I) has been the first human retrovirus identified and then associated with a definite pathological entity, a leukemic syndrome that specifically affects mature T-lymphocytes (ATL, adult T-cell leukemia), expressing CD3+, CD4+, CD8-, CD11- phenotype. This form of leukemia/lymphoma is endemic in southwestern islands of Japan, although at present the number of HTLV-I seropositive individuals has greatly increased, with a worldwide diffusion, following the expansion wave of the AIDS-associated HIV retrovirus. In fact, double seropositivity for both HIV and HTLV is frequently found among intravenous drug users. Although ATL leukemia or lymphoma occurs with a low frequency among HTLV-I seropositive individuals, it is likely that the evolution from a latent phase of infection to acute leukemia could be favoured by depression of immunosurveillance levels in the host. Therefore, special attention is required to prevent the diffusion of this retrovirus in adults, taking into consideration that newborn babies from seropositive mothers have to be considered at high risk for development of HTLV-I associated disease, on the basis of their immature immunocompetence.

As part of a military universal HIV screening program, 442 men were assessed for the presence of DSM-III-R defined psychiatric disorders and symptoms of anxiety and depression after notification of HIV seroconversion. Of them, 84.4% were in the earliest, asymptomatic stages of disease at the time of interview (96% did not have AIDS). The Structured Clinical Interview for DSM-III-R and Structured Interview Guide for the Hamilton Anxiety and Depression Scales were used. Relevant comparisons were made to Epidemiologic Catchment Area prevalence data. HIV seropositive men were more likely than age-matched men in the community to have current diagnoses of major depression (ages 18-44) and anxiety disorders (ages 25-44). Higher lifetime rates of major depression and alcohol use disorder, and high current prevalence of sexual dysfunction (21.7%) were noted. We conclude that men who become HIV seropositive have high rates of mood and substance use disorders prior to knowledge of seroconversion, and that early in the course of HIV infection men are at risk for developing major depression, anxiety disorders, and disorders of sexual desire.

The lymphocyte responsiveness to leishmanial antigens and its influence on the course of cutaneous leishmaniasis was studied in a patient with AIDS-associated American cutaneous leishmaniasis caused by Leishmania braziliensis. The patient had cutaneous disseminated erythematous papules or nodules and mucosal lesions as well as moniliasis and weight loss. The patient had a poor delayed-type hypersensitivity to leishmanial antigens, showing 3 mm of induration. The cellular immune responses were studied in vitro by lymphocyte proliferative assays induced by leishmanial antigens and concanavalin A. The T cell phenotypes were analysed by flow cytometry. The peripheral blood mononuclear cells before proliferation showed an inversion of the CD4/CD8 ratio (0.28:1). The lymphoproliferative responses to antigen and mitogen were very low (indices < 2.5). The blast-like cell phenotypes after antigen stimulation in culture were: CD3+ 44.8%, CD4+ 7.53% and CD8+ 17.45%. In AIDS patients the decrease in the pool of CD4+ cells, and consequent diminution of the CD4/CD8 ratio, produced by HIV infection provokes a generalized immune depression. The patient's disseminated clinical picture was probably related to the inability of his T cell-mediated immune responses to control the spread of Leishmania infection.

Levels of anxiety and depression were assessed for 207 HIV seropositive homosexual/bisexual men (AIDS = 34, ARC = 72, asymptomatic HIV infection = 101), and 36 seronegative controls. Lymphocyte subset enumeration, history of opportunistic infections, and occurrence of HIV-related symptoms were recorded at the time of assessment. No differences between groups were found on age, educational level, state/trait anxiety or depression scores. Neither the number of symptoms reported, their duration, severity, frequency of occurrence, nor the proportion of patients who reported a specific symptom was different between the three HIV seropositive groups. Severity of anxiety and depression was related to the magnitude of symptomatology, but not associated with either degree of immunodeficiency, number of opportunistic infections or diagnostic group. Principal component analysis extracted five symptom factors (cognitive, affective, psychosocial, neurological and physical), none of which predicted state anxiety scores. However, affective and psychosocial symptom factors predicted trait anxiety and depression scores. The results indicate that ratings of anxiety and depression are independent of stage of HIV infection, may be in part mediated by constitutional and physical symptoms of HIV disease, but are primarily associated with the presence of psychological and psychosocial symptoms.

RU-486 or mifepristone is best known as an antiprogestin and an abortifacient, but it has broad medical applicability. The drug is also a potent blocker of corticosteroid receptors, and it has shown promise in the treatment of breast cancer, inoperable meningioma, and cushing's disease. Cushing's is a model for the symptomatology of aging which may involve enhanced response to corticosteroid. RU-486 has reversed the osteoporosis, thinning of skin, muscle atrophy, obesity, adult onset diabetes, depression, hypertension, and immunosuppression associated with this disease. RU-486 may be of value in aiding cervical dilation, lactation, and the treatment of endometriosis. In addition, breast, bowel, kidney tumors, hepatomas, endometrial cancer, and fibrosarcomas can show corticosteroid dependency, suggesting that RU-486 may have clinical value against inoperable tumors. In a preliminary 1987 phase I study, in estrogen-positive, chemotherapy-refractory breast cancer patients in Montpelier, France, Ru-486 produced objective tumor regression (6 of 22) that was prolonged (3 months) in 4 patients. Clinical relief of bone pain was observed in 7 of 23 patients with a decline in carcinoembryonic antigen (CEA) tumor makers in 8 patients. Growing in vitro data also show that RU-486 can directly inhibit breast cancer cell proliferation. RU-486 has application for HIV infection, based on data that there is a serum factor in AIDS patients that enhances corticosteroid lympholysis. IN addition, the immune restorative action of RU-486 suggests that it could counteract the immunosuppression seen in aging, in cancer, or in viral or stress-related disease, which has recently focused clinical attention on its potential in the treatment of senile dementia and depression. Scientific conferences and workshops are needed to alert scientists, physicians, and the public to the potential medical benefits of this drug.

The authors describe a weekly group for caregivers of children with HIV disease which began in January 1988. Presented are four separate developmental stages: (1) universality; (2) development of cohesion; (3) development of conflict; and (4) separation and growth. This group has reduced the members' depression, anxiety and isolation and has assisted them with anticipatory mourning and the creation of a support network.

Human immunodeficiency virus (HIV)-related oral candidiasis affects approximately one third of HIV-seropositive patients and more than 90% of patients with AIDS. It is necessary to identify patients who have a greater risk of candidiasis developing, so that interventions can be designed to reduce the frequency. This is particularly important because there is evidence that Candida species are immunosuppressive and therefore candidiasis may adversely affect the prognosis of patients with HIV. Susceptibility to HIV-related oral candidiasis is associated with xerostomia, severity of disease, depression of cell-mediated immunity, and older age (greater than 35 years). The frequency of HIV-related oral candidiasis is notably increased when the CD4 lymphocyte count falls to less than 300 cells/mm3. Xerostomia appears to be a better predictor of HIV-related oral candidiasis than CD4 count and should be prevented (e.g., by avoiding xerogenic drugs) and treated, when necessary, to minimize the risk of oral candidiasis.

Depression of cellular and humoral immunity can result in an overwhelming infection with the mite Sarcoptes scabiei. Infections in which the densities of mites are very high are known as Norwegian, or crusted, scabies. Cases of Norwegian scabies have been reported sporadically in patients with AIDS, but the appearance of the rash on these patients can be very misleading because of the diffuse papular or psoriasiform presentation. Such patients may readily transmit scabies to others. Since the disease is curable, it should be considered in the differential diagnosis of any persistent papular or psoriasiform rash on a patient with AIDS.
