The natural history of HIV infection in intravenous drug users: risk of disease progression in a cohort of seroconverters.

A multicentre cohort study was carried out to estimate the incidence of AIDS and HIV-related conditions in newly infected intravenous drug users (IVDU). The enrollment criteria included the identification of the seroconversion time. Two hundred and five subjects entered the study, and were followed for a mean of 26 months. Twelve subjects developed clinical AIDS over a 4-year period. The actuarial incidence of AIDS estimated by Kaplan-Meier survival technique was 17.8% by 4 years since seroconversion. The risk of developing AIDS increased significantly after 24 months from seroconversion. Relatively small figures accounted for the lack of statistical association between the risk factors investigated and the disease status.

Differences in knowledge of and risk factors for AIDS between Hispanic and non-Hispanic women attending an urban family planning clinic.

Risk factors for AIDS, contraceptive use, seroprevalence of HIV, and level of knowledge before and after an AIDS education session were assessed for 657 clients attending a family planning clinic in Los Angeles, USA. History of a partner who was bisexual, an intravenous drug user, or a blood transfusion recipient were the most common risk factors. Spanish speakers reported fewer traditional risk factors than English speakers. They were also less likely to report a history of drug or alcohol use or sexually transmitted diseases, and to have had fewer sexual partners. Less than one-third of the women identified as being at risk of exposure were using condoms. None of 351 consecutive patients tested for HIV antibodies was positive. English speakers scored higher on both pre- and post-tests of knowledge about AIDS. Cultural factors may lower the personal risk of HIV exposure for Spanish-speaking women, but lack of knowledge about AIDS and partner behavior may increase risk.

Evaluation by women consulting in a family planning centre of their risk of HIV infection.

In order to assess women's self-perception of their risk of infection by HIV, research was performed among 654 women who had consulted in a family planning centre in the Paris region. Of the 452 (69%) women who took part in this research, 77% considered themselves as 'not at risk of carrying the AIDS virus', 11% as 'at risk' and 12% did not give a specific answer. The most important risk factors noted by the patient and the doctor were found to be the number of partners, the use of syringes and the non- or faulty use of condoms. Estimates of the risk of infection by physicians had a high correlation with those of the women, although there were wide differences between the opinions of the six doctors involved. In one case out of three the doctors were unable to decide whether or not their patient was at risk. The evident difficulties experienced by these physicians show an urgent need for the development of specific medical training programmes. The seroprevalence of 2.4% of HIV infection among the women studied, and 1.1% of those who consulted during the study period, confirm the importance of carrying out specific studies on women consulting in family planning centres.

Latent Haemophilus influenzae pneumonia in patients infected with HIV.

Pneumonia caused by common pyogenic bacteria occurs frequently in HIV-infected patients. Its clinical presentation has been described as being similar to that seen in non-immunosuppressed hosts but clearly different to that of opportunistic pneumonias. An atypical presentation has rarely been seen. In a 10-month period, we saw 12 HIV-infected patients who presented with Haemophilus influenzae pneumonia which was clinically and radiologically indistinguishable from Pneumocystis carinii pneumonia. Ten of the patients were intravenous drug users and were in different stages of HIV disease. The clinical picture was characterized by a prolonged course (median 4 weeks), non-productive cough, dyspnoea, and absence of findings usually present in bacterial pneumonia. Laboratory data frequently showed absence of leukocytosis, increased lactate dehydrogenase levels, hypoxaemia, and decreased CD4+ cell counts. All presented with interstitial or mixed bilateral infiltrates. Resistance to ampicillin and trimethoprim-sulphamethoxazole were each found in seven cases. Eleven patients were cured with antibiotic therapy, although five relapsed. H. influenzae pneumonia should be considered in HIV-infected patients who present with pulmonary symptoms and bilateral infiltrates of subacute or chronic onset. Clinical resolution of pneumonia is the usual outcome, but recurrences of infection are frequent.

Pulmonary tuberculosis in HIV-infected patients with normal chest radiographs.

SUBJECTS: Three HIV-infected patients with active pulmonary non-disseminated tuberculosis and normal chest radiograph at clinical presentation and during follow-up are reported. Patients had cough and fever but no other specific symptoms. Löwenstein cultures of specimens from bronchoalveolar lavage in two cases and induced sputum in one yielded Mycobacterium tuberculosis. CONCLUSIONS: The diagnosis of tuberculosis in HIV-infected patients depends greatly on clinical suspicion by the physician, because of its atypical presentation. Failure to perform appropriate diagnostic tests in HIV-infected patients who present with suspected pulmonary disease will result in underdiagnosis and undertreatment of tuberculosis.

Assessing behavioral risk for HIV infection in family-planning and STD clinics: similarities and differences.

Four hundred fifty-five women in family-planning and sexually transmitted disease (STD) clinics were surveyed to determine the degree of participation in behaviors known to be associated with increased risk of human immunodeficiency virus (HIV) infection. A previous history of STD (20%) and multiple sexual partners (73%) were shown to be the high-risk behaviors most prevalent in these populations. Sexual intercourse with persons in high-risk groups (6%) and intravenous (IV) drug use (3.7%) were less prevalent. Differences between the populations from each type of clinic and between races were noted. Overall, almost one third of family-planning clinic clients and nearly half of STD clinic clients reported participation in at least one risk behavior, emphasizing the need for educational efforts toward disease prevention in these settings.

Tobacco epidemic or bonanza? The global connection.

There seems to be ample agreement that tobacco is an addictive harmful substance. The smoking epidemic is most noticeably affecting third world countries but the developed world despite overoptimistic predictions is still far from safe. Profits derived mainly from tobacco trading in poor countries are being used to target vulnerable groups in more developed countries. The fight against smoking in developing countries is hindered by many internal and external factors. The socioeconomic situation is so desperate that governments are prepared to hand over the health of their people as part of payment. Some developed countries have consistently applied double standards to dealing with harmful drugs, not only ignoring the smoking epidemic affecting less developed countries but also actively protecting and encouraging its spreading. The fight against drugs, including smoking, badly needs a real proof of commitment from these countries.

Chile: perspectives in school health.

The leading health problems of children and adolescents in Chile is reviewed. The Chilean educational system and how the system addresses its principal health problems are described. A school health program is described as well as other educational programs designed and developed by nongovernmental institutions which have a smaller coverage. Current research studies regarding growth and development, child morbidity, nutritional level, and mental health studies are reviewed. In addition, principal challenges that include developing more efficient ways of referring children, enriching the curriculum and teacher training, assigning school hours for health teachers, and enlarging coverage of the health care evaluation programs are outlined. Of special importance is developing prevention programs for parents and children using school and community leaders to prevent health problems in areas such as human sexuality education, decision-making, social abilities, and alcohol and drug abuse. Main efforts should be directed toward low-income families and children to improve life conditions.

Human immunodeficiency virus and female prostitutes, Sydney 1985.

One hundred and thirty two female prostitutes and 55 non-prostitutes who were tested for antibodies to human immunodeficiency virus (HIV) were surveyed by questionnaire at this centre. The two groups were well matched for age and were very similar in other except for numbers of their sexual partners. Questions were asked about drug taking, sexual practices, general health, and episodes of sexually transmitted diseases (STDs). None of the women in the survey was found to be seropositive, but both groups were found to be seriously at risk of HIV infection through using intravenous (IV) drugs, having unprotected sexual intercourse with men who used IV drugs, having unprotected sexual intercourse with bisexual men, or exposure to several STDs.

Safe sex and women.

OBJECTIVE: Sexual behaviour, condom use, HIV knowledge and anxiety for women were examined to understand the range of sexual behaviours, predictors of safer sex and the extent of relapse. DESIGN: A cross sectional sample of women STD clinic attenders completed interviews and questionnaires. SETTING: Central London STD Clinic. SUBJECTS: 153 women drawn from consecutive attenders at a sexually transmitted disease (STD) clinic in inner London. RESULTS: A quarter of the sample had never responded to safe sex and a further 14% had been unable to maintain it over time. Anxiety and knowledge did not differ between safe and relapsed groups, but self efficacy and cognitive variables did. Those who maintained safe sex had significantly less sex. Ten percent of the sample had unprotected anal intercourse. Most women saw themselves in longer term relationships, yet a quarter had sex outside of the relationship and a fifth stated that their partners also did. HIV information gathering was passive and 74% felt they could not protect themselves against infection. High concern over HIV was monitored. Condom uptake was low and non-existent for anal intercourse. 25% had undergone HIV testing. These women did not differ significantly in terms of their behaviour from the untested women. CONCLUSIONS: HIV risks for women are a source of anxiety and tailored intervention is needed to reduce risk and promote dialogue and negotiation.

Adolescent physical abuse: risk for adolescent psychiatric disorders.

OBJECTIVE: The present study examined whether physical abuse functions as an additional risk factor for adolescent psychopathology after other important known risk factors are controlled for. METHOD: The authors recruited 99 adolescents aged 12 to 18 years directly from the New York State Department of Social Services after official documentation of physical abuse. The abused adolescents were compared to 99 nonabused adolescents matched for age, gender, race, and community income. Diagnostic interviews and measures of selected risk factors for psychopathology were administered to the adolescents and their parents and then entered into a multiple logistic regression model testing the added risk contributed by physical abuse to adolescent psychopathology. RESULTS: Physical abuse added significantly to other risk factors in accounting for lifetime diagnoses of major depression, dysthymia, conduct disorder, drug abuse, and cigarette smoking. Physical abuse also contributed significantly to prediction of current adolescent unipolar depressive disorders, disruptive disorders, and cigarette smoking. CONCLUSIONS: Since physically abused adolescents are at greater risk for the development of psychiatric disorders, recognition of adolescent abuse and the provision of psychiatric and substance abuse services may reduce morbidity.

Risk of HIV infection among Dutch expatriates in sub-Saharan Africa.

In order to study the prevalence of human immunodeficiency virus (HIV) infections and related risk factors, Dutch expatriates returning from sub-Saharan Africa were asked to complete a questionnaire on sexual, occupational and other risk factors, and to donate a sample of blood to test for antibodies against HIV. The 1968 participants were workers of various professions and their family members over 16 years of age posted in sub-Saharan African countries by Dutch governmental, non-governmental and commercial organizations for at least 6 months cumulative time between 1 January 1979 and 1 January 1990. Antibodies against HIV-1 were found among 4 of 1122 men (0.4%) and 1 of 846 women (0.1%). The woman and 3 of the men had had sexual contact with African partners and had been treated for sexually transmitted diseases, 2 of these 3 men also had an African life partner. One man reported occupational exposure only. Of the 1968 participants 89 men (7.9%) and 18 women (2.1%) lived with an African partner; 344 men (30.7%) and 111 women (13.1%) had heterosexual contact with other African partners. Only 22.3% (men) and 18.6% (women) of casual sexual contacts with African partners were always protected by a condom. Two hundred and thirty-two of 408 (56.9%) (para)medics reported needlesticks. Groups at risk of HIV infection through sexual exposure were identified using logistic regression models. In conclusion, the observed prevalence of HIV-1 is low. However, unprotected sexual contact with African partners and needlestick accidents were common. This study underscores the continuous need for health education of expatriates on the risks of transmission of HIV in Africa.

Alcohol and drug use during sexual activity and compliance with safe sex guidelines for AIDS: the AIDS Behavioral Research Project.

This article describes the association between drug and alcohol use during sexual activity and high-risk sex for AIDS. Data to test this association are drawn from a prospective study of the behavioral changes made by gay men in San Francisco in response to the AIDS epidemic. Findings drawn from the May, 1984 and May 1985 waves of data collection are described. The cross-sectional analysis showed that use of particular drugs during sex, the number of drugs used during such activity, and the frequency of combining drugs and sex are all positively associated with risky sexual activity for AIDS. The retrospective data showed that men who currently abstained from combining drug use with sexual activity were likely to have been at no risk for AIDS over two measurement points during the previous year. The men who currently combined drug use with sex were most likely to have a history of high-risk sexual activity over the previous year. These findings show a strong relationship between drug and alcohol use during sex and non-compliance with safe sex techniques to prevent the spread of AIDS. Implications of this relationship for AIDS health education efforts are discussed.
