The differential diagnosis of homosexuality.

The treatment of homosexuality presents serious difficulties owing to its multifactorial aetiology and variety of psychopathological views. It is suggested that the combined use of psychiatric and psychoanalytic models can contribute to the establishment of a satisfactory differential diagnosis. Out of the innumerable clinical types seen in practice and described in the literature, three major groups can be isolated. The homosexuality which occurs on the background of hysterical, obsessional and other neurotic personality types and related psychiatric conditions, tends to be linked with latent heterosexuality and responds well to all forms of psychotherapy. On the other hand, true homosexuality is often the major presenting symptom of borderline states, narcissistic disorders, psychopathy and the schizo-affective psychoses and carries an unfavourable prognosis with any form of treatment. Cases of actual bisexuality form the third group with its own specific psychopathology. The homosexual solution is seen as a defence and is regarded as a matter of survival for many individuals. It should be treated with the utmost caution by anyone who attempts to remove it.

A model-based estimate of the mean incubation period for AIDS in homosexual men.

Because of the difficulty in identifying the date of exposure to type 1 of the human immunodeficiency virus (HIV-1) infection in persons other than transfusion recipients, studies of the incubation periods for acquired immunodeficiency syndrome (AIDS) have been limited. When data from a cohort of 84 homosexual and bisexual men that provided the information to determine the years of conversion of sera infected with HIV-1 were analyzed, a model for the proportion likely to develop AIDS and the incubation period for AIDS in homosexual men could be derived. The maximum likelihood estimate for the proportion of infected homosexual men developing AIDS is 0.99 (90% confidence interval ranging from 0.38 to 1). Furthermore, the maximum likelihood estimate for the mean incubation period for AIDS in homosexual men is 7.8 years (90% confidence interval ranging from 4.2 years to 15.0 years), which is close to the estimate of 8.2 years for adults developing transfusion-associated AIDS.

HTLV-III in saliva of people with AIDS-related complex and healthy homosexual men at risk for AIDS.

Peripheral blood leukocytes and saliva from 20 individuals, including four with the acquired immune deficiency syndrome (AIDS), ten with AIDS-related complex (ARC), and six healthy homosexual males at risk for AIDS, were compared as sources of transmissible human T-cell leukemia (lymphotropic) virus type III (HTLV-III), the virus found to be the etiologic agent of AIDS. All of the AIDS and ARC patients and four of the six healthy homosexuals had evidence of prior exposure to HTLV-III as indicated by seropositivity for antibody to HTLV-III structural proteins. Infectious virus was isolated from the peripheral blood of one of the AIDS patients, four of the ARC patients, and two of the healthy homosexual males, consistent with previous reports. HTLV-III was also isolated from the saliva of four of the ARC patients and four of the healthy homosexuals. Virus was also observed by electron microscopy in material prepared by centrifugation of the saliva of one AIDS patient. Although AIDS does not appear to be transmitted by casual contact, the possibility that HTLV-III can be transmitted by saliva should be considered.

Gonococcal strains from homosexual men have outer membranes with reduced permeability to hydrophobic molecules.

Loci designated penA, penB, and mtr contribute additively to penicillin G resistance in Neisseria gonorrhoeae; the mtr locus also confers resistance to hydrophobic dyes, detergents, and antibiotics, env mutations suppress the phenotypic expression of mtr and penB and are responsible for increased sensitivity to various hydrophobic molecules. We postulated that the host environment is important in the selection of gonococcal strains with these particular outer membrane phenotypes. Thus, mtr strains should predominate in environments that are high in hydrophobic molecules. To test this hypothesis we determined the outer membrane phenotype of 152 strains of N. gonorrhoeae. Rectal and urethral isolates from 58 homosexual men, urethral isolates from 55 heterosexual men, and cervical and rectal isolates from 39 heterosexual women were used in this study. Strains from 43 of the homosexual men were matched with those from heterosexual men with respect to auxotype and year and season of isolation. Cell envelope phenotype was determined for each strain on the basis of its resistance to various hydrophobic compounds. The identity of mtr strains was confirmed by genetic transformation. Among the matched pairs, mtr strains were significantly more prevalent among isolates from homosexual men than among those from heterosexual men (P = 0.03). Serogrouping by coagglutination demonstrated that 17 of 19 mtr strains versus 76 of 131 non-mtr strains belonged to coagglutination group WII (P = 0.01). Coagglutination group WII strains were also associated with homosexuality (P = 0.02). Gonococci were also tested for resistance to fecal lipids, mtr strains were more resistant to growth inhibition by fecal lipids than were non-mtr strains.

Immunologic function in a cohort of human immunodeficiency virus type 1-seropositive and -negative healthy homosexual men.

The study objectives were to determine the early effects of human immunodeficiency virus type 1 (HIV-1) infection on both phenotypic and functional immunologic markers in healthy homosexual men, to ascertain the relationships of these markers to each other, and to discover which markers were affected by enrollment in an AIDS study in which HIV-1 serostatus would be determined. The major findings were as follows. (i) The CD4/CD8 ratio and lymphocyte proliferative response to pokeweed mitogen were the characteristics most affected by early HIV-1 infection. (ii) The loss in CD4 cells observed in the HIV-1-positive homosexual men was entirely due to diminished numbers of the memory subset. CD4+ CD29+. The reciprocal subset of CD4, CD4+ CD45RA+, did not differ in the two groups of homosexual men at either time point or in the controls. (iii) Prior to learning their HIV-1 serostatus, HIV-1 antibody-negative risk-group males had lower phytohemagglutinin (PHA) responses than the controls did. In the assays following notification of their seronegativity, however, these men had PHA values which were not different from those of the controls. In the HIV-1-positive group, the responses to both PHA and pokeweed mitogen were below those of both HIV-1-negative groups and did not change after serostatus notification. (iv) The activity of natural killer cells was lower in the risk-group men than in the controls at both pre- and postdiagnosis but was not related to HIV-1 serostatus. (v) In this cohort of homosexual men, the CD4/CD8 ratio correlated significantly with the functional measures of immunologic status in the HIV-1-positive men, but not in the HIV-1-negative men.

Infectious cellular load in human immunodeficiency virus type 1 (HIV-1)-infected individuals and susceptibility of peripheral blood mononuclear cells from their exposed partners to non-syncytium-inducing HIV-1 as major determinants for HIV-1 transmission in homosexual couples.

To study risk factors for homosexual transmission of human immunodeficiency virus type 1 (HIV-1), we compared 10 monogamous homosexual couples between whom transmission of HIV-1 had occurred with 10 monogamous homosexual couples between whom HIV-1 transmission had not occurred despite high-risk sexual behavior. In the group of individuals who did not transmit virus, peripheral cellular infectious load was lower and the CD4+ T-cell counts were higher than in the group of transmitters. HIV-1 RNA levels in serum did not differ between transmitters and nontransmitters. Compared with peripheral blood mononuclear cells (PBMC) from normal healthy blood donors, 8 of 10 nonrecipients and only 3 of 8 recipients had PBMC with reduced susceptibility to in vitro infection with non-syncytium-inducing (NSI) HIV-1 variants isolated from either their respective partners or an unrelated individual. No difference in susceptibility was observed for infection with a syncytium-inducing variant. Among the individuals who had PBMC with reduced susceptibility, five nonrecipients and one recipient had PBMC that were equally or even less susceptible to NSI variants than PBMC that had low susceptibility and that were derived from healthy blood donors that were heterozygous for a 32-bp deletion in the CCR5 gene (CCR5 delta32). Three of these individuals (all nonrecipients) had a CCR5 delta32 heterozygous genotype themselves, confirming an association between low susceptibility to NSI variants and CCR5 delta32 heterozygosity. All three recipients with less susceptible PBMC had partners with a high infectious cellular load; inversely, both nonrecipients with normally susceptible PBMC had partners with a very low infectious cellular load. These results suggest that a combination of susceptibility of target cells and inoculum size upon homosexual exposure largely determines whether HIV-1 infection is established.

Seminal fluid excretion of cytomegalovirus related to immunosuppression in homosexual men.

Seminal fluid samples from 84 Danish homosexual men were successfully cultured to determine the prevalence of cytomegalovirus excretion. Ten (15%) out of 66 men positive for the antibody were found to be excreting the virus. Although the proportion excreting was inversely related to age (p less than 0.01), three men aged over 30 and with many years of homosexual experience excreted the virus. In addition, a 50 year old man with Kaposi's sarcoma excreted the virus. A further study of the ratio of T cell helpers to suppressors in the men aged over 30 and a series of age matched non-excreting homosexual control or heterosexual men showed that those excreting cytomegalovirus in their seminal fluid had statistically lower ratios (all less than 0.77) than the controls (p less than 0.05). Excretion of cytomegalovirus may be related to re-emergence of latent infection in immunosuppressed homosexual men.

Trends in sexual behaviour and risk factors for HIV infection among homosexual men, 1984-7.

To assess whether the spread of infection with HIV can be reduced by changes in behaviour among groups most at risk because of their sexual practices sexual behaviour was monitored among 1050 homosexual men tested for HIV infection at a genitourinary medicine clinic in west London from November 1984 to September 1987. Four cohorts, defined by date of presentation, were studied by questionnaire at their presentation, and blood samples were analysed. Between the first and last cohorts there was a considerable fall in the proportion reporting casual relationships (291/329 (88%) v 107/213 (50%] and high risk activities, such as anoreceptive intercourse with casual partners (262/291 (90%) v 74/106 (70%], with the greatest changes occurring before the government information campaign began in 1986. Nevertheless, half of the men in the last cohort studied reported having casual partners. Multiple logistic regression showed that behavioural risk factors for HIV infection most closely resembled those for hepatitis B and that previous sexually transmitted diseases (syphilis, hepatitis B, and anogenital herpes) were themselves independent risk factors. A history of syphilis ranked above anoreceptive intercourse as the strongest predictor of HIV infection. Actively bisexual men showed a much lower prevalence of HIV infection (3/57, 5%) than exclusively homosexual men (113/375, 30%). Sexual behaviour among homosexual men changed during the period studied, and the incidence of HIV infection fell, although more education programmes directed at homosexual men are needed to re-emphasise the dangers of infection.

Androsterone-etiocholanolone ratios in male homosexuals.

Analyses of 24-hour specimens of urine from healthy adult males for androsterone and etiocholanolone produced values which, when calculated as discriminant scores, discriminated between heterosexual and exclusively homosexual individuals. This confirms a previous study.No significant differences were found between heterosexuals and homosexuals in parental ages, secondary sex characteristics, genitalia, anthropometry, 17-ketosteroids, and 17-ketogenic steroids.A significant difference was found between the heterosexual group and homosexual group in the number of homosexual relatives in the immediate and extended families.

Trends in sexual behaviour among London homosexual men 1998-2003: implications for HIV prevention and sexual health promotion.

OBJECTIVES: To examine changes in sexual behaviour among London homosexual men between 1998 and 2003 by type and HIV status of partner. METHODS: Homosexual men (n=4264) using London gyms were surveyed annually between 1998 and 2003 (range 498-834 per year). Information was collected on HIV status, unprotected anal intercourse (UAI) in the previous 3 months, and type of partner for UAI. High risk sexual behaviour was defined as UAI with a partner of unknown or discordant HIV status. RESULTS: Between 1998 and 2003, the percentage of men reporting high risk sexual behaviour with a casual partner increased from 6.7% to 16.1% (adjusted odds ratio (AOR) 1.36 per year, 95% confidence interval (CI) 1.26 to 1.46, p <0.001). There was no significant change in the percentage of men reporting high risk sexual behaviour with a main partner alone (7.8%, 5.6%, p=0.7). These patterns were seen for HIV positive, negative and never tested men alike regardless of age. The percentage of HIV positive men reporting UAI with a casual partner who was also HIV positive increased from 6.8% to 10.3% (AOR 1.27, 95% CI 1.01 to 1.58, p <0.05). CONCLUSION: The increase in high risk sexual behaviour among London homosexual men between 1998 and 2003 was seen only with casual and not with main partners. STI/HIV prevention campaigns among London homosexual men should target high risk practices with casual partners since these appear to account entirely for the recent increase in high risk behaviour.

Homosexuality and venereal disease in the United Kingdom. A second study. British Co-operative Clinical Group.

The proportion of homosexually acquired cases of primary and secondary syphilis in patients attending venereal disease clinics in the United Kingdom has risen from 42.4% to 54% over a six-year period. Similarly, over the same period, the proportion of homosexually acquired cases of gonorrhoea has risen from 9.8% to 10.9%. The increase in incidence of homosexually acquired infections in both diseases occurred in all areas but particularly in London. Thus the very considerable epidemiological importance of male homosexuals as a high-risk group should receive more, not less, emphasis.

Social factors in homosexually acquired venereal disease. Comparison between Sweden and Australia.

The prevalence of venereal disease was studied in homosexuals in two countries, Sweden and Australia, which are similar apart from their different legal and social attitudes to homosexuality. Social attitudes were not generally associated with differences in the numbers of infections and reinfections in homosexual men with sexually transmitted diseases. Using a non-clinical sample there was some evidence that sexually transmitted diseases in homosexuals are grossly overestimated if cases rather than individuals are used as an index. Furthermore, the incidence of syphilis was related to the numbers of partners and the latency of symptoms in both societies.

Antibodies to cytomegalovirus in homosexual and heterosexual men attending an STD clinic.

We studied the prevalence of antibody to cytomegalovirus (CMV) in 262 men (132 homosexual, 20 bisexual, and 108 heterosexual) attending the sexually transmitted diseases (STD) clinic at this hospital. Antibody to CMV at a titre of 1/4 or more was found in 92% of the homosexuals, 80% of the bisexuals, and 56% of the heterosexuals (p less than 0.0001). Among heterosexuals, but not homosexuals, nationality and social class showed a significant association with antibody to CMV. In both heterosexuals and homosexuals a history of gonorrhoea was more common in patients with antibody to CMV than in those without it. A similar finding was seen in heterosexual men with a history of non-specific urethritis (NSU). Using a series of log linear models, sexual orientation was shown to be the most important determinant of antibody to CMV in this population.

Patterns of homosexually acquired gonococcal serovars in Edinburgh 1986-90.

AIM: The aim of this study was to observe the changes in gonococcal serovar pattern in homosexual men over a 5 year period. METHODS: All men who presented to the Genitourinary Medicine clinic at Edinburgh Royal Infirmary between 1986 and 1990 with homosexually acquired gonococcal infection were included in the study. Gonococcal isolates were serotyped and the temporal change in isolated serovars noted. RESULTS: Over the 5 year period 32 different serovars were associated with 175 homosexually acquired infections. There was a dynamic temporal change in the dominant serovars with a continual influx of new strains some of which become established in the community but most of which appeared only transiently. Rapid variation in incidence over time was observed for certain serovars while others remained at more constant levels. There was a marked association between certain serovars (Ae/Av; Back/Bropyt; Bacejk/Brpyut; Bacejk/Brpyust; Baejk/Brpyut) and homosexually acquired infection. CONCLUSIONS: Possible determinants for the patterns observed are discussed but the underlying mechanism is probably multifactorial.

Genital colonisation and infection with candida in heterosexual and homosexual males.

OBJECTIVES: To determine the penile, perianal, and oropharyngeal candidal colonisation rates among homosexual and heterosexual males attending an STD clinic. To determine the prevalence of balanitis and candidal balanitis in the two groups. SUBJECTS: 252 heterosexual and 210 homosexual male patients attending consecutively the STD clinic in Coventry, England. DESIGN: A prospective study recording sexual behaviour, relevant history, symptoms, and examination. Specimens for candida culture were collected from the glans penis, perianal area, and oropharynx. RESULTS: Among the 462 men studied, penile, perianal, and oropharyngeal colonisation rates were 74 (16%), 70 (15%), and 116 (25%) respectively. On examination, 47 (10%) were found to have balanitis. Of the 74 patients with penile colonisation, 26 (37%) were symptomatic and 20 (27%) had balanitis. The 223 heterosexual and the 196 homosexual males who had sexual intercourse within 3 months had comparable colonisation rates of candida on the penis, perianal area, and oropharynx. Balanitis was seen in 31 heterosexuals (14%) and candidal balanitis in 16 (7%); the incidence was significantly less in homosexuals where balanitis was seen in 12 (6%) and candidal balanitis in four (2%). CONCLUSIONS: Itching or burning sensations after sex were the most common symptoms associated with penile colonisation with candida and were present in more than one third. Candidal balanitis was commoner in those who had vaginal than those who had anal intercourse within 3 months.

The Gay Men's Task Force: the impact of peer education on the sexual health behaviour of homosexual men in Glasgow.

OBJECTIVE: To assess the impact of a peer education intervention, based in the "gay" bars of Glasgow, which sought to reduce sexual risk behaviours for HIV infection and increase use of a dedicated homosexual men's sexual health service, and in particular increase the uptake of hepatitis B vaccination. DESIGN: Self completed questionnaires administered to men who have sex with men (MSM) in Glasgow's gay bars. SUBJECTS: 1442 men completed questionnaires in January 1999, 7 months after the end of the 9 month sexual health intervention. MAIN OUTCOME MEASURES: Self reported contact with the peer education intervention, reported behaviour change, and reported sexual health service use. RESULTS: The Gay Men's Task Force (GMTF) symbol was recognised by 42% of the men surveyed. Among men who reported speaking with peer educators 49% reported thinking about their sexual behaviour and 26% reported changing their sexual behaviour. Logistic regressions demonstrated higher levels of HIV testing, hepatitis B vaccination, and use of sexual health services among men who reported contact with the intervention. These men were more likely to have used the homosexual specific sexual health service. Peer education dose effects were suggested, with the likelihood of HIV testing, hepatitis B vaccination, and use of sexual health services being greater among men who reported talking to peer educators more than once. CONCLUSION: The intervention had a direct impact on Glasgow's homosexual men and reached men of all ages and social classes. Higher levels of sexual health service use and uptake of specific services among men who had contact with the intervention are suggestive of an intervention effect. Peer education, as a form of health outreach, appears to be an effective intervention tool in terms of the uptake of sexual health services, but is less effective in achieving actual sexual behaviour change among homosexual men.

Prospective study of cytotoxic T lymphocyte responses to influenza and antibodies to human T lymphotropic virus-III in homosexual men. Selective loss of an influenza-specific, human leukocyte antigen-restricted cytotoxic T lymphocyte response in human T lymphotropic virus-III positive individuals with symptoms of acquired immunodeficiency syndrome and in a patient with acquired immunodeficiency syndrome.

Peripheral blood leukocytes (PBL) from 18 homosexual men who did not have acquired immunodeficiency syndrome (AIDS) and from 9 heterosexual men were repetitively tested for their ability to generate HLA self-restricted cytotoxic T lymphocyte responses to influenza virus (flu-self) over a 2-yr period. The sera of the same donors were tested for antibodies to human T lymphotropic virus-III (HTLV-III). Six of the homosexual and none of the heterosexual donors consistently generated weak cytotoxic T lymphocyte responses to flu-self. Seven of the homosexual and none of the heterosexual donors were seropositive for antibodies to HTLV-III. No obvious correlation was detected between weak flu-self cytotoxic T lymphocyte responses and antibodies to HTLV-III. However, one homosexual donor generated no detectable cytotoxic T lymphocyte activity to flu-self, although he was a strong responder to HLA-alloantigens. This donor had an OKT4:OKT8 ratio of 0.4 and was seropositive for HTLV-III antigens; HTLV-III virus was identified in his PBL; and he developed AIDS during the course of this study. A second donor with lymphadenopathy and who was seropositive for HTLV-III antigens exhibited marginal cytotoxic T lymphocyte activity to flu-self which he subsequently lost. PBL from two patients, one with Kaposi's sarcoma and one with generalized lymphadenopathy, were also tested for cytotoxic T lymphocyte responses to flu-self and to alloantigens. Both donors failed to generate cytotoxic T lymphocyte to flu-self, but generated strong cytotoxic T lymphocyte responses to alloantigens. The selective loss of an HLA-restricted cytotoxic T lymphocyte response without loss of HLA alloantigenic cytotoxic T lymphocyte activity may be an important functional immunologic characteristic in the development of AIDS.

Behaviors and attitudes related to eating disorders in homosexual male college students.

To investigate whether homosexuality predisposes males to eating disorders, the authors studied 48 nonpatient homosexual male students at UCLA. The homosexual men had higher prevalences of binge-eating problems, of feeling fat in spite of others' perceptions, of feeling terrified of being fat, and of having used diuretics than other male students. They also scored higher on the Eating Disorders Inventory scales for drive for thinness, interoceptive awareness, bulimia, body dissatisfaction, maturity fears, and ineffectiveness. One of the 48 homosexual men and one of the 300 comparison group men met criteria for probable past histories of eating disorders.
