In the West, 1 of the most common opportunistic bacterial infections in AIDS patients is Mycobacterium avium-intracellulare (MAI). Physicians have diagnosed it in 15-20% of AIDS patients before they died, and it was identified in 50% of dead AIDS patients. Only 2 cases have been diagnosed in Africa. Before AIDS began afflicting the human population, dissemination of MAI was rare, but in AIDS patients the degree of dissemination is widespread and has been found, at least, in the spleen, lymph nodes, lung, liver, and gastrointestinal (GI) tract. The portal of entry in MAI infections has not been clearly identified, but some evidence suggests that in AIDS patients the disseminated infection enters through the GI tract. Response to antibiotic treatment for MAI in AIDS patients is poor. Other nontuberculous mycobacteria, such as M. kansasii and 1 case of M. leprae, have also been found in association with AIDS. In the United States, tuberculosis is often associated with AIDS, especially if the cases are black, of foreign origin (particularly from Haiti), or had a history of intravenous drug abuse. Tuberculosis in AIDS patients is more likely to be lymphatic and disseminated than pulmonary. 1 study revealed that 30% of AIDS cases with tuberculosis had pulmonary tuberculosis compared with 80% of those with only tuberculosis. Further, pericardial disease commonly accompanies tuberculosis in AIDS patients. The treatment for tuberculosis in AIDS patients is standard antituberculous drugs. It appears that, at least in the case of tuberculosis, HIV infection causes reactivation of latent infections 1st acquired in childhood. Further research on the association of mycobacterial infection and AIDS will lead to a greater understanding of the immune defense system in all types of patients.

We report here the results of a survey of 308 intravenous drug abusers recruited from hospital-based methadone maintenance or drug detoxification programmes located in Manhattan, New York City. Complete interviews and serological analyses for antibodies to human immunodeficiency virus (HIV) using both enzyme-linked immunosorbent and Western blot assays were obtained from 290 (94%) of the subjects. HIV antibodies were found by both assays in 147 (50.7%) of the tested subjects; conflicting results were found in three (1%) of the subjects; and negative results on both tests were found in 140 (48.3%) of the subjects. Logistic regression analysis identified significant relative risks for HIV infection associated with the frequency of drug injection and the proportion of injections in 'shooting galleries'. Additional risk among men was associated with a history of homosexual relations. Traditional efforts taken by subjects to clean syringes between uses, such as washing with water or alcohol, showed no evidence of being protective. Programmes aimed at prevention of HIV infection should focus on reducing use of shooting galleries and sharing of needles and syringes as well as reducing intravenous drug abuse generally.

Of about 40 patients with presumed enteropathic Acquired Immune Deficiency Syndrome (AIDS), i.e., oral thrush, diarrhea, and weight loss, admitted to Mulago Hospital medical wards, Uganda, from October through November 985, 23 patients were studied with upper gastrointestinal tract endoscopy and stool examination. Those patients chosen for study suffered with diarrhea, weight loss, and oral candidiasis and were willing to tolerate endoscopy. Weight loss was not quantified in most patients, but generally it was profound. 10 of the patients gave a history of genital sores or venereal disease. There were 16 males and 7 females with an age range of 19-47 years. All were sexually active, and all denied homosexuality anal intercourse, and intravenous drug abuse. 4 patients had had blood transfusion. The 23 patients represented a cross-section of the population with most social classes included. 20 patients were seropositive with antibody to HIV. Specimens from 2 patients were lost. 1 patient was seronegative. Apart from 5 patients who had been treated with nystatin for oral thrush and clinically presumed esophageal candidiasis, all the patients had oral thrush at the time of endoscopy. 20 patients had obvious esophageal candidiasis, and 1 patient had the appearance of Kaposi's sarcoma in the esophagus. Stool examination and histology of the upper GI tract showed that 11 patients had cryptosporidiosis and 3 had isosporiasis (total of 61% of patients with coccidian enteritis). 1 case of Mycobacterium avium mycobacteriosis also was identified. The incidence of cryptosporidiosis and isosporiasis is higher in Uganda than in developed countries.

We report 36 patients with non-Hodgkin's lymphomas (NHL) and 10 patients with Hodgkin's disease (HD), predominantly intravenous drug abusers (IVDA; 35 patients), diagnosed in 16 different Italian centers. The group of NHL has a median age of 26 years (range 16-64): 26 were IVDA, 3 polytransfused, 3 IVDA and homosexual men, 2 homosexual men and 2 without apparent risk for AIDS but carrying HIV antibodies. 81% of the evaluable patients had high-grade NHL (32% Burkitt's type) according to the Working Formulation, 15% intermediate and 4% low-grade. Out of 23 patients with stage reported, 16 (70%) were stage IV, 2 (9%) stage III, 1 (4%) stage II and 4 (17%) stage I (CNS involvement). The group with HD has a median age of 25 years (range 20-40), 9 were IVDA and 1 IVDA and homosexual. Of the 7 patients with subtype reported, 4 patients had nodular sclerosis and 3 mixed cellularity subtype. Stage III and IV were reported in 66% of the patients. The median survival is 4 months for NHL and 10 months for HD. The most common cause of death is opportunistic infection in 86% of the evaluable cases.

Techniques adapted from population and community ecology, quantitative geography, and epidemiology are applied to ecosystem and environmental index data on the Bronx in an attempt to understand the origins and potential impacts of rampant spread of human immunodeficiency virus (HIV) and its sequelae of acquired immunodeficiency syndrome (AIDS) in that borough: Recent work by Drucker and Vermund (1987), ("Estimating Prevalence of Human Immunodeficiency Virus Infection in Urban Areas with High Rates of Intravenous Drug Abuse: A Model of the Bronx in 1987," Poster presented at the Third International Conference on AIDS, June 2, 1987) estimates HIV seroprevalence levels of from 8 to 21% among men of age 25-44 in the south Bronx, at this writing, comparable to the cities of Central Africa. It is found that the "South Bronx" process of fulminating, contagious urban decay which devastated the region in the 1970s, and its associated forced population migrations, spread intravenous drug abuse, the principal HIV vector in the Bronx, from a geographically contained center in the South-Central Bronx to a virtually borough-wide phenomenon. This has significantly complicated attempts to contain HIV infection, both by shredding the social networks which are the natural vehicles for education, and by vastly enlarging the area requiring intensive targeting. Since the "planned shrinkage" municipal service cuts which triggered the "South Bronx" burnout persist, and since levels of housing overcrowding now approach those of the early 1970s in the Bronx, it is expected that a new outbreak of contagious urban decay will occur, likely again dispersing population and seriously compromising any in-place HIV control strategies. If overt AIDS itself becomes a contributor to urban deterioration in overcrowded neighborhoods susceptible to "South Bronx" process, we could then see a nonlinear ecosystem coupling between AIDS, contagious urban decay, and population shift. Elementary mathematical models are provided. Thus, in striking contrast to the middle-class male homosexual community, successful control of HIV infection in the Bronx, and by inference in other devastated ghetto communities, seems predicated on quick reestablishment of demographic stability: The tools to make the tools for control must first be reconstructed. Necessary elements of any program toward this end are briefly outlined. AIDS in the Bronx and similar areas, like tuberculosis, seems increasingly a marker disease of extreme poverty, and again like tuberculosis, seems increasingly a marker disease of extreme poverty, and again like tuberculosis, may well form an important reservoir for further spread or resurg

A random, stratified sample of 2601 adult Australians from all states and territories was interviewed about knowledge of the acquired immunodeficiency syndrome (AIDS). After the interview, an anonymous questionnaire on the prevalence of practices that are associated with risk of human immunodeficiency virus (HIV) infection was left with the respondents; 60.2% of these questionnaires were returned. Data from this survey suggest that the prevalences of male homosexual behaviour, prostitute contact and lesbian contact are substantially lower than were estimated previously. Men with homosexual experience were significantly more prevalent in the more populous states, but the majority of other risk factors--intravenous drug abuse, male respondents' contact with prostitutes, transfusion of blood or blood products during 1980-1985 and heterosexual contact--showed few significant associations with geographical, occupational or marital status. Intravenous drug abusers were significantly younger, and heterosexual contact was associated with age for both male and female respondents. No significant differences were found in the prevalence of homosexual contact among single, married and previously-married men, although the prevalence of homosexual contact was lower in married men. The results of the study are discussed in terms of targeting preventive campaigns and assessing the future potential for the spread of HIV infection.

A young female patient with a long history of intravenous drug abuse died after a fulminant course of aplastic anemia. At postmortem examination, she was found to have multinucleate giant cells and immunocytochemical evidence of human immunodeficiency virus (HIV) infection of the central nervous system. This case raises the possibility that HIV infection contributed to the patient's aplastic anemia, and suggests that HIV-associated giant cells might be found retrospectively or prospectively within the brains of patients who die of conditions other than those narrowly defined as acquired immune deficiency syndrome (AIDS) or AIDS-related complex (ARC). It furthermore emphasizes that HIV infection of the nervous system is not necessarily accompanied by clinically apparent neurological disease.

The Presidential Commission was created in September 1987 with the mandate to advise the White House "on the public health dangers including the medical, legal, ethical, social, and economic impact, from the spread of the HIV and resulting illnesses including AIDS, AIDS related complex, and other related conditions." This paper covers the Commission's interim policy recommendations as of March 15, 1988, in the areas of intravenous drug abuse, patient care, and basic research and drug development. The scope of recommendations in the area of intravenous drug abuse includes provision of treatment services, treatment research, drug abuse prevention, and outreach education. There must be a national policy of "treatment on demand" for drug users. An expanded program of drug treatment research must include research on cocaine as well as heroin addiction treatment. Drug abuse prevention should coordinate efforts at all levels of government as well as community and religious organizations and schools. Outreach education, which is especially difficult with drug users because drug use is illegal, will cost roughly $126.5 million a year over current funding. Outreach programs should train and utilize street outreach workers, including former addicts, and should have special focuses on adolescents, minorities, and women of childbearing age. The scope of recommendations in the area of patient care includes health care provider education, health care systems, psychosocial needs, nursing care, minorities and underserved populations, and information coordination and exchange. AIDS needs to be integrated into the educational curricula of medical and all other health professional schools. In the area of health care systems, the recommendations emphasize the need for integrated community-based services for people with HIV infection. 22 AIDS Service Delivery Demonstration projects are currently being conducted in the US, 13 funded by the US Public Health Service and 9 funded by the Robert Wood Johnson Foundation.

Two hundred fifty individuals from high risk categories were enrolled in a seroprevalence survey for human immunodeficiency virus (HIV) infections in Winnipeg. The overall seroprevalence in the Manitoba AIDS Virus Epidemiology Study (MAVES) was 5.2%. Of 2651 diagnostic and screening specimens in the province of Manitoba submitted over a similar period, 103 were positive (3.9%). HIV seropositivity in Manitoba was noted mainly in homosexual/bisexual males (especially those who were also intravenous drug abusers), hemophiliacs, and individuals from endemic regions of the world. Individuals whose only risk factor was intravenous drug abuse, those with sexually transmitted diseases, or those with high risk sex contacts have not demonstrated HIV seropositivity in Manitoba to date. Manitoba is currently a low seroprevalence region for HIV infection. Our study demonstrated that the awareness level of people at risk for HIV infections was low. In our study population, one-on-one counseling was demonstrated to be an effective way to improve short-term knowledge about HIV infections. Appropriate education approaches must be considered for Native/Metis peoples (26.4% of our MAVES study population), who were younger and had a lower educational and employment level compared to Caucasian/other racial groups.

In order to evaluate the frequency of sexual transmission of human immunodeficiency virus (HIV) among promiscuous heterosexuals, we studied the prevalence of HIV infection among a group of predominantly Caucasian call girls and women working for escort services and massage parlors in New York City. In the 78 subjects studied, the mean age was 31.6 years and the mean duration of prostitution was 5.1 years. Study participants each had a median of 200 different sexual partners in the preceding year. Six women had a history of intravenous drug abuse and none had a history of any other recognized risk factor for HIV infection. Ninety percent of the women studied used condoms during intercourse with at least some of their partners. One of the six women with a history of drug abuse and none of the 72 non-drug-abusers were seropositive for HIV. This study indicates that despite their promiscuity, HIV infection is still uncommon in call girls in New York City.
