Specific antibody responses to synthetic peptides of HIV-1 p17 correlate with different stages of HIV-1 infection.

Antibodies were determined against five synthetic peptides (epitopes) of HIV-1 p17 in the sera of an immunologically and clinically well-characterized cohort (N = 292) of HIV-1 seronegative and HIV-1 seropositive high-risk homosexual men, HIV-1 seropositive i.v. drug abusers (IVDA), and AIDS patients. The synthetic peptides, representing the entire HIV-1 p17 protein sequence were: HGP-33 (aa 1-33), HGP-19 (aa 34-52), HGP-35 (aa 51-85), HGP-30 (aa 85-114), and HGP-17 ala (aa 114-131). The presence of one or more peptide-specific antibodies in the sera of all of the HIV-1 p17-positive subjects indicated that all five peptides contain B-cell epitopes. No antibodies were found in the sera of heterosexual controls, HIV-1 seronegative high-risk men, or asymptomatic HIV-1 seropositive but p17 antibody-negative study subjects. Significant differences in antibody recognition profiles to the peptide epitopes were found among the various study groups. A significantly higher proportion of HIV-1 seropositive IVDA had antibodies specific to HGP-17 ala (aa 114-131), HGP-35 (aa 51-85), and HGP-33 (aa 1-33) compared to the HIV-1 p17-positive asymptomatic homosexuals. The epitope-specific antibody responses reflected the clinical status of the HIV-1-infected study subjects, and declined to nondetectable levels as the patient progressed to ARC/AIDS. This decline preceded by several months the reduction in the antibody titer against the intact HIV-1 p17 and p24 proteins.(ABSTRACT TRUNCATED AT 250 WORDS)

Women in the HIV epidemic.

In the United States, the majority of women with HIV/AIDS are women whose lives have been touched by injection drug use--their own or that of their sexual partners. The pattern of opportunistic infections in women is more similar to that of injection drug users than that of homosexual men. Specific complications associated with a woman's reproductive tract include persistent Candida vaginitis, human papillomavirus infections, cervical dysplasias, and, possibly, pelvic inflammatory disease. Childbearing decisions for women with HIV infection are complex and culturally mediated. Meeting the challenge of providing high quality services to women with HIV infection requires major changes in the service delivery system.

A parametric family of correlation structures for the analysis of longitudinal data.

In epidemiological settings, we are often faced with numerous short time series, and a parsimonious parametrization of the correlation structure is desired in order to optimize the efficiency of the estimation procedure. We propose a damped exponential correlation structure for modeling multivariate Gaussian outcomes. The correlation between two observations separated by s units of time is modeled as gamma s theta, where gamma is the correlation between elements separated by one s-unit, and theta is a damping parameter. For (theta = 0), (theta = 1), and theta----infinity), the correlation structures of compound symmetry, first-order autoregressive, and first-order moving average processes are obtained. Although the AR(2) dependency structure, and the combination of random effects and AR(1) errors are not special cases of the proposed parametric family, these structures can be well approximated within the family for short time series. Maximum likelihood methods for parameter estimation and interpretations of intermediate models (0 less than theta less than 1) are discussed in the context of modeling pulmonary function in an adult population in The Netherlands and T-cell subsets in homosexual men infected with human immunodeficiency virus Type I.

Therapeutic regimens for anorectal gonococcal infection in males.

Anorectal gonococcal infection is particularly prevalent in women and homosexual men. Although the currently recommended Public Health Service therapeutic regimens for uncomplicated gonorrhea appear to be effective also for anorectal gonorrhea in women, their efficacy for anorectal infection in men has not been adequately evaluated. We report a case of gonococcal proctitis in a homosexual man that did not respond to therapy with ampicillin plus probenecid and tetracycline, but subsequently responded to spectinomycin therapy. Currently available therapeutic regimens for anorectal gonococcal infection in males are reviewed.

Sexual patterns and human immunodeficiency virus infection among homosexuals in Taiwan.

Between 1988 and 1991, 64 homosexual men and 43 bisexual men were screened for human immunodeficiency virus (HIV) in Southern Taiwan; 5 of them were found to carry HIV antibodies. According to a self-administered questionnaire completed before screening, the average age of the men in the study group was 27 years, and the average duration of practiced homosexuality was 3.8 years. Occupations included student, merchant, laborer, officer, and soldier, and many of the men (45/107) had some junior college or university level education. A relatively high proportion (48/107) of these subjects reported having only 1 sexual partner, and there was a significant association between HIV antibody status and number of sexual partners (P = 0.025). Of the 107 subjects, 58 had practiced anal intercourse and more than a third of them (37/107) indicated that they had participated in receptive anal intercourse, 42 in insertive anal intercourse, and 21 in both of the above. All five carriers of HIV had practiced receptive anal intercourse, in which transmission of HIV from inserter to receptor was highly likely (P = 0.004). Of the men who came forward for HIV testing, the bisexual men tended to be older and often married.

[Sexually transmitted infections in HIV-positive persons].

In 1989 and 1990, newly-acquired sexually transmitted bacterial disease was found in 41 HIV-antibody-positive men seen at a sexually transmitted disease (STD) clinic in Copenhagen. In 38 homo/bisexual men, the new STD was transmitted from a male contact in 36 cases and from a female contact in two cases. In three male intravenous drug users, the new STD was transmitted from a female contact. In two men, the HIV-infection was first diagnosed together with the new STD, the other men had been aware of their HIV-infection for a mean period of 38 months. Gonococcal infections were diagnosed in 33 men, Chlamydial infections in ten men and syphilis in three men. Anorectal gonococcal infections were found in 13 men, corresponding to 43% and 30% of the total number of anorectal gonococcal infections in 1989 and 1990 respectively. The data presented might indicate a relapse to unsafe sexual practices among homosexual men in Copenhagen. This could influence the HIV prevalence as at least 12% of the contacts were known to be HIV-antibody-negative.

Impact of HIV testing and counseling on subsequent sexual behavior.

To assess sexual behavior changes after voluntary HIV testing and routine counseling, we interviewed 235 persons at 2 anonymous test sites in North Carolina. Among the 57 (24%) persons returning for follow-up 1 year later, 70% were male; 44% were black, 37% were homosexual, 10% were bisexual; and 16% were HIV positive. Overall, 28% of returnees at the initial visit and 33% on the follow-up visit admitted to having 2 or more sexual partners in the past month. At the initial interview and at follow-up, 21% of returnees reported condom use in the past month. Homosexual men were significantly less likely to use condoms during anal sex over time (58% non-use initially vs. 74% non-use at follow-up, p = 0.04). No significant net change in high-risk sexual behaviors was found at follow-up. Overall findings indicate that the standard HIV testing and counseling provided by health departments anonymously and free of charge does not result in elimination of high-risk sexual behaviors or initiation of safer sex behaviors among those at high risk for HIV infection.

[AIDS in Germany: clinical manifestations of AIDS].

Since 1982, voluntary anonymous reports that meet the criteria of the WHO/CDC-AIDS definition are being collected by the Federal Health Office. By December 31st, 1989 a total of 4,306 AIDS cases has been registered. More than 80% of the reported cases are homo- and bisexual men and injection drug-users. The remaining cases are divided between hemophiliacs, persons who get infected by heterosexual contacts, blood transfusion recipients, and children infected pre- or perinatally. In 16% of all cases AIDS was diagnosed only on the basis of a Kaposi's sarcoma (KS) and in another 6% on the basis of KS and an opportunistic infection (OI). KS occurred mostly in homo- and bisexual men. The relative proportion of KS has steadily decreased from 30% up to 1986 to less than 20% in 1989. The overall incidence of KS decreased mainly due to the decrease of KS in homosexual men with AIDS. OI were diagnosed in 70% of the cases. Pneumocystis-carinii-pneumonia is most frequent (47%), followed by candida-oesophagitis (19%) and toxoplasmosis of brain in 9.5%. A malignant lymphoma was diagnosed in 3% of the cases. Furthermore, HIV-encephalopathy was seen in 2.8% and HIV-wasting-syndrome in 1.6% of cases. There is a different spectrum of diseases at the first manifestation of AIDS diagnosed in injecting drug-users. The reasons for this may be due to different life-style in this group.

The fate of Don Juan: the myth and the man.

The literary character of Don Juan has offered an opportunity to study certain characteristics in an adult man who began a behavior pattern in adolescence that resembled the legendary and mythical Don Juan. Power and dominating control issues were paramount defenses against a narcissistic depression in this man as seen in his relationships with women and in the transference relationship with me. The transference data have been put to use in providing a formulation for an explanation of the phenomena observed. Other clinical data concerning women and some homosexual men are presented in a more abbreviated fashion. This research effort is a retrospective construction of the dynamics that led to this man's neurosis. In my opinion, a self psychological interpretation offers the more felicitous fit than the classic oedipal interpretation. In fact, at first I tried interpretations based on classic oedipal theory--concerning issues of competition with me as father and fear of retaliation and castration--but this strategy resulted in little or no response. More important than symptomatic response, however, the data minimally and weakly supported those interpretations. To be sure, there were and still are competitive and phallic oedipal issues. Moreover, when the patient's mother died, he was drawn into a closer relationship with his father, a relationship accompanied by wishes and fantasies of taking his mother's place. These wishes were quite real, but, as the analysis preceeded, this negative oedipal configuration occupied a much less prominent place in the dynamics. Power and control issues dominated the clinical picture, masking a depression emanating from a deeper narcissistic focus. Interpretation of these narcissistic issues provided my patient with the relief he was seeking, while the main effect of the antidepressant medication was to help him sleep. By giving him something, a deeply seated wish was gratified and was in keeping with an idealized mother transference.

[Homosexuality in childhood and adolescence].

Every second homosexual man has a presentiment of his own homosexuality during childhood. 86 percent of the homosexual men feel it till eighteen. The selfrecognition is a way full of conflicts between ignoration and acceptance; sometimes it ends in deformation of the personality or even in suicide. For well advice of homosexual children and adolescents we indicate: firstly an early sexual education in the school including information on homosexuality and secondly the academic and postgradual education of physicians, psychologists and pedagogues on natural variants of human sexuality.

A system for surveillance of voluntary HIV testing: results of the first 2 years, 1989-1990.

OBJECTIVE: In 1988, in order to improve the already established surveillance of AIDS and HIV-infected cases in Scotland, UK, the Communicable Diseases (Scotland) Unit [CD(S)U], in collaboration with microbiologists responsible for HIV testing, instituted a routine system for the epidemiological surveillance of all voluntary HIV tests. METHODS: To facilitate information capture, a standardized HIV request form was introduced for use throughout the country by clinicians requesting an HIV test. In addition, a network of laboratory computers, operated by clerical personnel, was established for the collection and collation of data. RESULTS: In 1989, of 9483 individuals tested for HIV, 129 (1.4%) were HIV-antibody-positive compared with 130 (1.2%) of 11,111 tested in 1990. A comparison of 1989 with 1990 rates of HIV among specific population groups, including injecting drug users (4.1%, 1989; 2.7%, 1990), homosexual men (5.2%, 1989; 4.5%, 1990), heterosexual men and women with high-risk partners (1.6%, 1989; 1.8%, 1990) and heterosexual men and women with lesser risk (0.3%, 1989; 0.5%, 1990), revealed no statistically significance differences at a 95% level of confidence. CONCLUSION: We believe that this surveillance system is the first of its kind to be implemented on a nationwide basis. The first 2 years' findings suggest a degree of stability in new transmissions of HIV occurring in Scotland. However, the increasing numbers of those known to be HIV-infected continue to cause considerable concern: 1943 individuals were reported to CD(S)U as HIV-antibody-positive by December 1991.

Evocability of a slight positive oestrogen feedback action on LH secretion in castrated and oestrogen-primed men.

Orchidectomized heterosexual men suffering from prostatic cancer with suppressed serum LH values by oestrogen priming exhibited a slight, but significant surge of LH secretion following oestrogen injection. In contrast, orchidectomized and oestrogen-primed heterosexual men with unsuppressed serum LH levels as well as intact heterosexual men did not display any positive oestrogen feedback action on LH secretion, as it was observed in intact homosexual men.

Examining the homosexual male for sexually transmitted diseases.

Homosexual men may be deterred from seeking an examination for sexually transmitted diseases because it would require an open admission of sexual preference. For these diseases to be controlled, gay men must be motivated to be examined for sexually transmitted diseases. If a medical or health professional feels unable to respond to a gay patient's needs, he should refer the patient to someone who deals well with gay patients. Health care services must be offered in a way that minimizes the anxiety many homosexuals associate with examination and treatment for sexually transmitted diseases.

The relationship of perceived societal hostility, conformity, and psychological adjustment in homosexual males.

The present study examined the relationship between the perception by homosexual males of positive or negative societal reaction to homosexuality (PSR), their degree of conformity to heterosexual norms, and their degree of psychological adjustment. In this study respondents with high PSR were those who perceived negative societal reaction to homosexuality. Respondents with low PSR were those who perceived positive societal reaction. The study differentiated between the effects of putative societal reaction and actual societal reaction and was based on a three-group sample of homosexual men who (a) were, (b) had been, or (c) had never been heterosexually married. Findings showed that putative societal reaction was a critical variable producing conformity and psychological maladjustment in homosexual males.

The gay bowel syndrome: clinico-pathologic correlation in 260 cases.

The clinical and pathological findings in a group of 260 homosexual men comprising 10% of a private proctologic practice are reviewed. A clinical pattern of anorectal and colon diseases encountered with unusual frequency in these homosexual patients is termed the gay bowel syndrome. The clinical diagnoses in decreasing order of frequency include condyloma acuminata, hemorrhoids, nonspecific proctitis, anal fistula, perirectal abscess, anal fissure, amebiasis, benign polyps, viral hepatitis, gonorrhea, syphilis, anorectal trauma and foreign bodies, shigellosis, rectal ulcers and lymphogranuloma venereum. 60 anorectal and sigmoid biopsies from 51 patients failed to disclose evidence of specific infection other than condyloma acuminata. Of 21 patients with biopsy diagnosis of nonspecific proctitis, 8 had a specific infection which was detected by other means,--5 cases of shigellosis and one case each of gonorrheal proctitis, amebiasis and lymphogranuloma venereum. In evaluating proctologic problems in the gay male, all of the known sexually transmitted diseases should be considered. Shigellosis, amebiasis and viral hepatitis should be included. Microbiological evaluation is essential. Concurrent infections with 2 or more pathogens should be anticipated. Chlamydia trachomatis, an important cause of nonspecific urethritis in the general population, is high on the list of possible causes of the nonspecific proctitis present in 31 of the 260 patients.

Sexual behavior patterns of customers of male street prostitutes.

Information about male customers of male prostitutes, including sociodemographic and life-style characteristics, sexual and drug use behaviors, and knowledge about HIV infection were collected from a convenience sample of 211 male street prostitutes and a convenience sample of 15 male customers as part of a feasibility study. Data from these two groups indicate that despite knowledge of HIV infection and its transmission, customers engage in high-risk sexual and drug use behaviors with prostitutes. Because there is a high HIV infection rate within the male prostitute sample (175/1000) and because these customers for the most part describe themselves as bisexual or heterosexual, it is likely that male customers of male prostitutes serve as a vector of transmission of HIV infection to their other partners including the heterosexual population.

The sexual behaviour of bisexual men in relation to HIV transmission.

Relatively little is known about the behaviour of bisexual men which may help in assessing their role in HIV transmission. A sample of 60 behaviourally bisexual men were asked about their sexual behaviour with male and female partners and their perceptions of risk of HIV infection. Only a minority of men engaged in unprotected anal sex with their male partners while two thirds had unprotected vaginal sex with their female partners. This asymmetrical pattern of sexual behaviour reflects a differential perception of risk of HIV infection with male and female partners. A quarter of the men had unprotected penetrative sex with both male and female partners in the previous year. The pattern of risk behaviour varied amongst men living in gay, heterosexual or bisexual contexts.
