Epstein-Barr virus is an important aetiological factor in certain HIV-related syndromes, with its opportunist expression related to the level of host immunodeficiency. In asymptomatic people co-infected with HIV, EBV activity is reflected by increased viral shedding and rises in anti-EBV titres; as immunodeficiency ensues EBV manifests as epithelial hyperproliferation in OHL, and later as B-cell lymphoma in AIDS. The suggested role of EBV as a co-factor in the progression of HIV infection and development of AIDS has not been established, although another herpesvirus, cytomegalovirus, might play such a role. Advances in our understanding of HIV regulation and its interaction with other latent (herpes) viruses should provide important molecular and pharmacological approaches to the clinical management of advanced HIV disease.

A method is described for detection of nonoxynol in condoms, based on methanol-water extraction followed by reverse-phase high-performance liquid chromatography. Using this method, we found that approximately 50% of the nonionic surfactant lubricant nonoxynol migrated into elastomers (rubber latex), resulting in a concentration of nonoxynol insufficient to inhibit human immunodeficiency virus (HIV) (less than 0.05%). In order to minimize the risk of sexual transmission of HIV, and to ensure spermicidal effect and optimal rubber properties, the concentration of nonoxynol in condoms, therefore, should either be increased, or nonoxynol should be packed separately. Further studies are needed to clarify and determine the solubility and migration of nonoxynols into elastomers.

As condylomata acuminata often persist in individuals infected with the human immunodeficiency virus (HIV), an immunohistological study of warts from infected men was undertaken to further knowledge about human papillomavirus persistence in this group. Using an indirect immunoperoxidase method and a panel of monoclonal antibodies, the phenotypes of cells were studied in cryostat sections of perianal or anal warts removed from 14 HIV-infected men (10 homosexual and 4 heterosexual) and from 16 non-infected men (10 homosexual and 6 heterosexual). Although the median numbers of CD1+, CD3+ and CD4+ cells per unit area were similar in each group of individuals, the number of CD8+ cells was significantly higher in HIV-infected homosexual men when compared with non-infected individuals and HIV-infected heterosexual men. The median CD4+ cell count in the peripheral blood was significantly higher in HIV-infected heterosexual men than in HIV-infected homosexual men (P less than 0.05). These findings may reflect differences in duration of HIV infection between the two groups. There was no significant difference in the proportion of cells expressing interleukin-2 receptors between HIV-infected and non-infected individuals. Natural killer (CD16+) cells were not identified in any of the condylomata.

Human immunodeficiency virus (HIV)-antibody screening of blood donors in northeastern Zaire was reviewed to determine overall seroprevalence in the population and to identify particular subgroups of the population who are at relatively high risk. Six hundred and seventy-five healthy blood donors were tested from March 1989 to May 1990 using either the HIV-CHEK or Karpas cell tests. A total of 25 donors (3.7%) were seropositive, and seropositivity was more common in female donors (5.4%) than in male donors (2.5%, P less than 0.05). Donors who came from major population centres had a higher rate of seropositivity than did individuals coming from rural villages (10.5% vs 2.0%, P less than 0.001). There was a tendency toward increasing seroprevalence during the 13 months of the study with 2.8% of donors positive in 1989 and 5.8% positive in 1990 (P less than 0.1). It is concluded that in healthy blood donors in northeastern Zaire: (1) HIV seropositivity is more frequent in women and in individuals coming from major population centres, and, (2) HIV seropositivity seems to be increasing rapidly.

The seroprevalence of human immunodeficiency virus (HIV) infection and syphilis was investigated among 181 female prostitutes in Tegucigalpa, Honduras. 1 particle agglutination test and 2 enzyme immunoassays, as well as 1 immunofluorescence test, were used for the screening of HIV antibodies. Confirmation of positive results by the screening tests was carried out by western blot. The prevalence of HIV seropositivity was 4% (8 women). Specific treponemal antibodies were found in 50% (90/181) of the prostitutes as judged by Treponema pallidum hemagglutination assay (TPHA) and/or fluorescent treponemal antibody-absorption (FTA-ABSIgG) test. As estimated by the positivity of any or both nontreponemal tests (VDRL and RPR), a total of 31 (17%) of 181 women had active syphilis. A good correlation was found between the results obtained by TPHA and FTA-ABSIgG. IgM antibodies were found in 72% of sera positive by TPHA and/or FTA-ABSIgG. 4 of 181 women were found to have antibodies to both HIV and Treponema pallidum.

To assess the clinical and laboratory workload arising from human immunodeficiency virus (HIV)-related inpatient admissions in a London teaching hospital, a 10-month retrospective audit was performed of the casenotes of all HIV-infected inpatients admitted under the care of one consultant physician. During this period, 84 inpatients were identified who generated 371 admissions, of whom 71 (84.5%) had acquired immunodeficiency syndrome (AIDS). Over two-thirds of admissions were essentially day cases, attributed to blood transfusions, antimicrobial and tumour, chemotherapy, and minor surgery; with blood transfusions alone accounting for 43% of all admissions. Pulmonary infections (pyogenic and cell-mediated opportunist) accounted for 46 (12%) of admissions, with Pneumocystis carinii pneumonia second only to blood transfusions in caseload prevalence score (see below). Neurological complications of AIDS were associated with the longest admissions. Laboratory-based investigations were heavily utilized by AIDS inpatients, particularly bacteriological services. Choice of radiological investigation correlated with the anatomical site of disease presentation: plain radiology for chest symptoms, ultrasound for abdominal symptoms and computerized tomography (CT scanning) for neurological presentations. Drug-induced anaemia accounted for a substantial number of HIV-related admissions for red cell transfusions, which together with the disproportionate workload from daycase-type admissions, might be better handled in lower dependency day wards.

The purpose of this study was to evaluate the usefulness of the HIV-CHEK kit for human immunodeficiency virus (HIV) antibody testing. A comparison with the Serodia-HIV test was made on 42 fresh serum samples. Both tests accurately identified the 11 true positive serum samples, while there was one false positive with the Serodia-HIV and 3 were difficult to interpret using the HIV-CHEK. To assess the sensitivity of the HIV-CHEK assay, a comparison with other tests was made using serial titrations of stored known HIV-positive frozen serum samples. Here the HIV-CHEK demonstrated a poor sensitivity compared to the others. In conclusion, although we found the HIV-CHEK to be simple and quick, the difficulty with interpretation of some specimens and the apparent poor sensitivity on frozen samples makes it difficult to recommend this kit in its present form as a principal initial screening test for HIV antibody.

One of the primary aims of acquired immunodeficiency syndrome (AIDS) prevention campaigns in the Netherlands has been to inform the public of the facts about AIDS, thereby stimulating informed, but voluntary action to prevent transmission of the human immunodeficiency virus (HIV). By conducting successive population surveys from April 1987 until October 1989, the effects of this approach were assessed. Twice a year, approximately 1000 respondents, a random sample from the general population, were interviewed about AIDS and safe sex. Additionally, condom sales figures and STD incidences were evaluated. It appears that knowledge about the prevention of HIV transmission with condoms has reached 98% of the sample. During the study, there was an increase in the number of people who expressed an intention to use condoms or who already used them. Behaviour, however, appeared to fall short of intention. The observations were confirmed by condom sales figures and STD incidences. We conclude that the AIDS policy in the Netherlands has had beneficial effects, reflected by several indices.

During four study periods, each of 3-4 weeks' duration in 1987 and 1988, all patients attending the Copenhagen outpatient Venereal Disease Clinic were encouraged to have a test for human immunodeficiency virus (HIV) antibody. Anonymous testing or testing for research purposes only without any data was also offered. Patients known to be HIV antibody-positive were not re-tested. A total of 1753 patients (1118 men, 635 women) were counselled and testing recommended. Testing was refused by 255 patients, 57 of whom had been tested (all negative) within the previous 3 months. HIV serology was therefore unknown in 11.7% (198 of 1696 persons), including 120 of 922 heterosexual men (13%), 16 of 159 homo/bisexual men (10%) and 62 of 615 women (10%). There was no substantial difference between the four study periods in the numbers refusing the test. Sixteen of the 1498 patients tested were HIV antibody-positive, including one woman and 3 men with a history of intravenous drug abuse and 11 homo/bisexual men; one heterosexual man with HIV antibodies had no known risk behaviour. It is concluded that HIV testing with informed consent at a sexually transmitted disease clinic will not include all persons, and therefore will not exclude a self-selection bias. Surveillance studies using unlinked HIV testing are therefore necessary and it is recommended that they should be performed in Denmark. In this study, unlinked HIV testing of the serum specimens taken for syphilis serology would have decreased the percentage of 'non-attenders' from 12.4% to 0.8% during the final study period.

This paper describes the workload of the AIDS Counselling Unit in Hampstead District Health Authority during its second year of service. Between April 1988 and March 1989, the average number of patients seen each month by the Unit doubled. It is anticipated that the caseload in the district will continue to increase, both among those with human immunodeficiency virus (HIV) infection and those without. New initiatives were developed within the district during the year. These included a new inpatient facility for patients with the acquired immunodeficiency syndrome (AIDS), the appointment of a designated HIV/AIDS consultant, and counselling services for people attending the antenatal clinic as well as those entering drug trials. Appropriate counselling services will need to be established in other health districts to meet local demand.
