Psychological status of men with haemophilia and HIV infection: two-year follow-up

This study aimed to assess the psychological status of men with haemophilia and HIV infection and to monitor changes in psychlogical status over time, in order to evaluate the need for psychological support. The study included 24 HIV seropositive men and a control group of 21 HIV seronegative men who attended the Haemophilia Centre in Bari (Italy). Subjects underwent psychological tests (STAl-Y: State and Trait Anxiety Inventory; SDS: Self-Rating Depression Scale) and completed a questionnaire on the emotional impact of AIDS. Assessment was repeated at 6-monthly intervals over a 2-year period. Contrary to expectation, HIV seronegative men with haemophilia had worse anxiety and depression scores, reported more confusion and fear, and had more reluctance towards the use of blood products (despite their present safety) than HIV seropositives. Possible reasons for these findings are considered, and their implications for clinical practice discussed.     

Effect of HIV antibody disclosure on subsequent sexual activity in homosexual men

During a prospective study of the natural history of AIDS, 1001 homosexual or bisexual men were offered the opportunity to learn their HIV antibody status. Six hundred and seventy (67%) of the population who elected to do so were similar to the 331 (33%) people who declined in a number of baseline characteristics. All were counselled to practice safe sex. To determine whether disclosure of HIV serologic status affects subsequent sexual behavior, we examined changes at four time-points in three sexual activities during the previous 6 months: the number of male partners with whom the participant had (1) sexual intercourse, (2) unprotected anal receptive intercourse, and (3) unprotected anal insertive intercourse. All activities decreased strikingly over the 18-month study period. Following disclosure, the mean number of partners dropped to 47% of the baseline number in people remaining unaware of their antibody status, to 45% in people told that they were seropositive, and to 55% in people told that they were seronegative. The mean number of partners for younger seropositives declined less than that for older seropositives. The mean number of partners with whom unprotected anal receptive intercourse was practiced declined to 57% of baseline in unaware people, 42% in aware seropositives, and 62% in aware seronegatives. The mean number of partners with whom unprotected anal insertive intercourse was practiced declined to 52% of baseline in unaware people, 42% in aware seropositives and 59% in aware seronegatives. Disclosure of a negative test result led to a significantly smaller decline in these sexual activities.(ABSTRACT TRUNCATED AT 250 WORDS)     

The impact of HIV antibody status on gay men's partner preferences: a community perspective.

As more gay men are tested for antibodies to human immunodeficiency virus (HIV), serostatus may influence the formation of primary partner bonds in this community. We compared seropositive (n = 157), seronegative men (n = 205), and those who had not been tested (n = 158) from our ongoing AIDS Behavioral Research Project (total response in 1988 = 540). Subjects responded to mailed surveys regarding sexual behavior, relationship status, HIV antibody testing and serostatus preference when forming relationships for romance and friendship. Sixty-eight percent of seropositive gay male respondents reported no serostatus preference in partners for romance, while 83% of seronegative respondents and 74% of untested respondents preferred seronegative partners for romance. In addition, 15% of seronegative respondents and 12% of untested respondents preferred seronegative individuals for friendship. Seropositive individuals were much less likely to be desired for romance or friendship by seronegatives and those who have not been tested--at a time when emotional support and companionship are obviously needed.     

Increased risk of bacterial pneumonia in HIV-infected intravenous drug users without AIDS

Although patients with AIDS have been noted to be at risk for bacterial pneumonia as well as opportunistic infections, little is known about the risk of bacterial pneumonia in HIV-infected populations without AIDS. To determine the incidence of bacterial pneumonia in a well defined population of intravenous drug users (IVDUs), and to examine any association with HIV infection, we prospectively studied 433 IVDUs without AIDS, enrolled in a longitudinal study of HIV infection in an out-patient methadone maintenance program. At enrollment, 144 (33.3%) subjects were HIV-seropositive, 289 (66.7%) were seronegative. Over a 12-month period, 14 out of 144 (9.7%) seropositive subjects were hospitalized for community-acquired bacterial pneumonia, compared with six out of 289 (2.1%) seronegative subjects. The cumulative yearly incidence of bacterial pneumonia was 97 out of 1000 for seropositives and 21 out of 1000 for seronegatives (risk ratio = 4.7, P less than 0.001). Eleven out of 14 (78.6%) cases among the seropositive patients were due to either Streptococcus pneumoniae [5] or Hemophilus influenzae [6]. Two out of 14 (14.3%) cases among the seropositives were fatal. Stratifying by level of intravenous drug use indicated that even among subjects not reporting active intravenous drug use at study entry, eight out of 82 (9.8%) seropositives compared with three out of 211 (1.4%) seronegatives were hospitalized for bacterial pneumonia over the study period (risk ratio = 6.9, P less than 0.01). This study shows a markedly increased incidence of bacterial pneumonia associated with HIV infection in IVDUs without AIDS.(ABSTRACT TRUNCATED AT 250 WORDS)     

HIV seroconversion in Swedish haemophiliacs: relation to type and dosage of factor concentrate

Human immunodeficiency virus (HIV) seroconversion among 40 Swedish haemophilia A patients has been investigated by retrospective sera testing. 22/40 patients had developed HIV antibodies before 1983, i.e., when heat-treatment of American factor concentrates was introduced. All patients had received American and Swedish factor concentrates, thus no case of seroconversion was seen among patients treated exclusively with non-heat-treated Swedish concentrates. Of 79 patients with severe or moderate haemophilia, all of whom had received both American and Swedish concentrates, the 36 seropositives were compared with the 43 seronegatives. The total number of units received did not differ between the two groups, though the seropositive group had received significantly more American concentrate. Two batches of concentrate were proved to have been infected. 29 seropositive and 13 seronegative patients had been treated with at least one of these batches. As expected, and unlike most of the seronegative patients, patients in the seropositive group generally had abnormal lymphocyte subsets.     

Psychological responses to serological testing for HIV

To determine the emotional impact of serological testing for HIV, 218 physically asymptomatic adults were evaluated in a confidential clinical setting 2 weeks before HIV test notification, immediately before and after notification, and 2 and 10 weeks later. All received extensive pre- and post-test counseling. The 179 seronegatives reported one or more HIV risk behaviors: homosexual intercourse (n = 111), heterosexual intercourse with possibly infected partners (n = 62), intravenous drug use (n = 20). Immediately after notification, seronegatives had significant decreases in visual analogue scale (VAS) measures of anxiety, depression, fear of getting AIDS, and fear of having infected others. Reductions were sustained at both follow-up assessments and were complemented by significant reductions on standardized self-reported measures of anxiety (Spielberger State Anxiety Inventory, SAI), depression (Beck Depression Inventory, BDI), and psychiatric symptoms (Brief Symptom Inventory, BSI) as well as by clinical ratings of depression (Hamilton Depression Rating Scale, HDRS). Of 39 seropositives, 35 had homosexual risk behaviors, seven had been intravenous drug users (IVDUs; four of whom were homosexual men), and one was a female partner of an IVDU. Immediately after notification, VAS measures of their anxiety were not significantly increased, and at 10 weeks after notification, their VAS measures of distress and mean scores on BDI, SAI and BSI were significantly lower than at entry. Their HDRS ratings were not significantly increased.     

Transmission of HIV to heterosexual partners of infected men and women

Future heterosexual spread of HIV will in part depend on the efficiency of transmission from men to women and from women to men. We studied seventy-eight female sexual partners of men infected with HIV and 18 male sexual partners of infected women. Participants were interviewed concerning sexual practices, use of contraception and other risk factors for HIV infection. Fifteen out of 78 (19.2%) female partners and one out of eighteen (5.5%) male partners were seropositive for HIV antibody. All couples had practised vaginal intercourse. Seropositive female partners did not differ significantly from seronegative partners with regard to length of relationship, number of acts of vaginal intercourse, other sexual practices, stage of clinical disease in the index case, or numbers of other sexual partners in the last five years. In two women, seroconversion was documented after one act of unprotected sexual intercourse. The majority of infected female partners (eight out of 15) had sexual relationships with men who were asymptomatic and did not practice anal intercourse. Biological factors such as variability in infectivity of the index case and susceptibility of the contact, as well as behavioural variables may be important in determining transmission.     

HIV infection and associated risk factors in female prostitutes in Kinshasa, Zaire

In Africa, female prostitutes represent a high risk group for HIV infection. In Kinshasa, Zaire, 101 (27%) out of 377 prostitutes were seropositive to HIV by ELISA and Western blot determination. Seropositivity was significantly associated with the number of lifetime partners with a median number of 600 partners, four seropositives and 338 for seronegative individuals (P = 0.02). Seropositivity was also significantly associated with a history of taking oral medications for the prevention of sexually transmitted diseases and/or pregnancy (odds ratio = 2.21, confidence interval = 1.2-4.2), and with the introduction of any product into the vagina for hygiene or other purposes (odds ratio = 2.3, confidence interval = 1.1-4.7). In addition, among 85 prostitutes reporting condom use by their sexual partners during the previous year, the use of condoms by 50% or more of partners was associated with a reduced risk of HIV seropositivity (P = 0.046). An increased risk of HIV seropositivity was not associated with fellatio, anal intercourse, or with any type of kissing. Twenty-nine per cent of prostitutes reported at least one symptom suggestive of HIV infection, and seropositivity was associated with weight loss, either with or without chronic diarrhea or pruritic dermatitis. These data confirm that African prostitutes are at high risk for HIV infection and that the number of lifetime sexual partners, and factors which interfere with the integrity of the vaginal or cervical mucosa, may be associated with an increased risk of HIV infection acquired through heterosexual contact.(ABSTRACT TRUNCATED AT 250 WORDS)     

The epidemiology of HIV transmission among paid plasma donors, Mexico City, Mexico

Screening of blood product donations for antibody to HIV began in Mexico in May 1986. From June to October 1986, the HIV cumulative seroprevalence increased from 6.3 to 9.2% in a commercial plasma collection center. Of the 281 people who donated the antibody-positive units, 62 (22.1%) had documented seroconversion during these 5 months. An epidemiologic study of 54 seropositive and 58 seronegative donors was carried out. The HIV serologic status did not change in any of these donors after repeat testing. Only 13.0% of the seropositives and 15.5% of the seronegatives had any of the known risk factors for AIDS. There was a direct relationship between frequency of plasma donation and the risk of being seropositive. A survey of employees disclosed the frequent re-use of disposable blood collection equipment. We conclude that HIV transmission had probably occurred in this plasma collection center.     

Drug-related behavior change for HIV transmission among American injection drug users

While high risk drug-related behaviors for human immunodeficiency virus (HIV) transmission among injection drug users (IDUs) are asserted to have declined over time in response to the AIDS epidemic, evidence from longitudinal cohorts has been sparse. In a cohort of 810 IDUs (442 seronegatives and 368 seropositives) in Baltimore, we identified drug-related risk behaviors at four consecutive semi-annual visits. Using robust methods for repeated measurements and multiple logistic regression, we estimated the probabilities of maintaining and reducing risk behaviors according to HIV serostatus and time in the study. Seropositive participants were more likely to maintain lower risk behaviors, and behavior maintenance increased with time in study for both seronegative and seropositive IDUs. Greater risk reduction (towards non-use and not sharing injection equipment) was seen among seropositive IDUs, with behavior change occurring soon after enrollment in the study. While behavior changes have been reported, many active IDUs, especially those still at risk for acquiring HIV infection, have not adequately reduced their risk. Continuing prevention programs and efforts in vaccine development are imperative to reduce the risk of HIV infection among IDUs.     

Combined HIV Prevention,the New York City Condom Distribution Program,and the Evolution of Safer Sex Behavior Among Persons Who Inject Drugs in New York City

Examine long term sexual risk behaviors among persons who inject drugs (PWID) in New York City following implementation of “combined” prevention programming, including condom social marketing. Quantitative interviews and human immunodeficiency virus (HIV) testing were conducted among PWID entering Beth Israel Medical Center drug treatment programs 1990–2012. Data were analyzed by four time periods corresponding to the cumulative implementation of HIV prevention interventions. 7,132 subjects were recruited from 1990 to 2012; little change in sexual behavior occurred among HIV seronegative subjects, while HIV seropositive subjects reported significant decreases in being sexually active and significant increases in consistent condom use. HIV transmission risk (being HIV positive and engaging in unprotected sex) declined from 14 % in 1990–1995 to 2 % in 2007–2012 for primary sexual partners and from 6 to 1 % for casual partners. Cumulative implementation of combined prevention programming for PWID was associated with substantial decreases in sexual risk behavior among HIV seropositives.     

Heterosexual transmission of human immunodeficiency virus: association with severe depletion of T-helper lymphocytes in men with hemophilia

We evaluated risk factors for human immunodeficiency virus (HIV) seropositivity in the wives/female sexual partners of hemophiliacs. One of the 6 seropositive women has developed the acquired immunodeficiency syndrome (AIDS). At least three of the others seroconverted during 1985-86, after more than four years of regular sexual contact with a seropositive hemophiliac. HIV seropositivity was present in at least 5 (50%) of the 10 female partners of hemophiliacs with severe depletion of T-helper cells (less than 100/microliters), including 3 (43%) of the 7 female partners of hemophiliacs with AIDS. All 4 HIV seropositive women with available data had vaginal intercourse without a condom, but risk of seropositivity did not appear to be affected by the frequency of vaginal intercourse or by hysterectomy. Other sexually transmitted diseases, anal intercourse, or vaginal intercourse during menstrual periods were not necessary for HIV infection. These data suggest that heterosexual transmission of HIV can occur during routine vaginal intercourse but that it usually does not occur until the hemophiliac has severe immune deficiency late in the course of HIV infection.     

Lymphocytes from some long-term seronegative heterosexual partners of HIV-infected individuals proliferate in response to HIV antigens.

A comparison of the proliferative responses of lymphocytes to human immunodeficiency virus (HIV) antigens from long-term, seronegative heterosexual partners of HIV-infected subjects, from normal unexposed controls and from healthy seropositive heterosexual partners or seropositive, asymptomatic men, reveals that lymphocytes from healthy seropositive individuals with strong proliferative responses to recall, microbial antigens respond only minimally to HIV proteins or envelope peptides, and that even these low responses do not occur in all individuals. If the frequency of responses to several HIV antigens are analyzed, lymphocytes from both HIV-exposed seropositive and seronegative partners of infected individuals proliferate to HIV antigens to a greater degree than lymphocytes from unexposed, normal control individuals. Although lymphocytes from seropositive partners proliferate to a greater degree than those from seronegative partners, the latter are more similar to seropositive partners than they are to normal controls. This observation suggests that these seronegative partners may have become sensitized to HIV antigens through sexual exposure but without infection, and/or that the presence or development of these small immune responses in some individuals might be associated with a failure to become infected.     

Transmission of HIV infection to heterosexual partners but not to household contacts of seropositive haemophiliacs

The prevalence of HIV antibodies in 44 heterosexual female partners and 56 nonsexual family household contacts of 61 HIV seropositive haemophiliacs (41 adults and 20 children or adolescents) was determined to evaluate the risk of transmission of HIV infection. HIV antibodies were determined by enzyme-linked immunosorbent assay and positive reactions were confirmed by Western blotting. HIV antibodies were demonstrated in 4/40 (10%) regular heterosexual partners of 40 seropositive patients with haemophilia A. Four temporary heterosexual partners of one additional seropositive haemophiliac were seronegative. 56 nonsexual household contacts including 30 parents, 13 siblings and 13 children of 29 seropositive haemophiliacs were all negative for HIV antibodies. Thus transmission of HIV occurred from seropositive haemophiliacs to their heterosexual partners but not to nonsexual household contacts.     

Neurologic Manifestations<br />of HIV Infection Without AIDS:Follow-UP of a Cohort<br />of Homosexual and Bisexual Men

To identify neurological abnormalities in HIV infection, 159 HIV-seropositive men without AIDS and 76 seronegative controls underwent standardized general and neurological examinations, lumbar puncture (LP), neuropsychological (NP) assessment, and brain magnetic resonance (MR) imaging. History, physical, and laboratory evaluations were repeated every six months. NP tests (all subjects) and MR imaging (seropositives only) was repeated every 6-12 months; LP (seropositives only) was repeated yearly. Mean follow-up was 24.6 months. Neurological abnormalities, most related to hearing, were seen in 60 (38.2%) of 157 seropositives and 23 (30.3%) of 76 controls at baseline (p = NS). During follow-up, 43 (31.6%) of 136 seropositives had persistent hearing abnormalities compared to 9 (14.1%) of 64 seronegatives (p = 0.008). Seven HIV-seropositives developed peripheral neuropathy; this was more common among those with hearing abnormalities (p = 0.03). HIV-seropositives performed less well on NP tests than controls, but overall performance did not decline. Worsening brain atrophy by MR imaging or cerebrospinal fluid abnormalities are more common in HIV-seropositives than seronegatives and may share a common mechanism with peripheral neuropathy. Further study is needed to determine whether these abnormalities portend more serious neurological disease.     

Lack of transmission of HIV to sexual and non-sexual contacts to HIV seropositive haemophiliacs following preventive information

In order to evaluate the risk of HIV transmission to sexual and non-sexual contacts to seropositive haemophiliacs, HIV antibodies, p24 antigen, immunoglobulin levels and lymphocyte subsets were analyzed in a cohort of Swedish haemophiliac families to 19 patients who seroconverted in 1980-82. As controls served contacts to 26 seronegative haemophiliacs. A total of 77 contacts were investigated. Except for 3 sexual partners who had seroconverted before 1985 no signs of HIV infection were detected. It was concluded that no HIV transmission occurred to household contacts of seropositive haemophiliacs and that transmission to heterosexual partners not appeared since 1985 when the patients and their families were informed about the risk of infection.     

Trends in sexual behaviour in a cohort of homosexual men: a 7 year prospective study.

A cohort of homosexual men at risk for human immunodeficiency virus (HIV) infection were studied prospectively over a 7-year period (1982/88) to assess trends in sexual behaviour and amyl nitrite intake. During the period, there were dramatic declines in the proportion of HIV seropositive and seronegative subjects reporting multiple casual partners for anal intercourse, unprotected anal intercourse and recreational use of amyl nitrite. Reported rates of orogenital intercourse remained the same during the period, whilst the total number of seroconversions fell from 17 for the period 1982-84 to 8 for 1985-88. High-risk sexual and related social behaviour among homosexual men, as assessed by patterns of anal intercourse behaviour and nitrite intake, changed over the 7-year period, with the greatest changes apparent before the widespread availability of HIV antibody testing and public education campaigns. This highlights the effectiveness of peer-group and community-based programmes in modifying the sexual behaviour of their members.     

Risk assessment for HIV infection: validation study of a computer-assisted preliminary screen

Development has been undertaken for microcomputer software intended to assess individual risk for HIV infection by analyzing personal case histories pertinent to drug abuse, receptive blood transfusion, and sexual behavior. The software performs interactive confidential interviews of individuals desiring expert assistance when deciding whether to commit to an antibody test. In the first phase of a validation study, 87 subjects responded to the computer interview. For each subject, human immunodeficiency virus (HIV) antibody status was on clinical record. This sample included 70 subjects, 29 of whom were HIV seropositive, recruited from the clientele of an AIDS antibody testing and counseling facility. In this phase, the software accurately assessed 28 of 29 seropositives (96.6%) to be at risk for HIV. The second phase was based upon participation of an additional 74 subjects who were undergraduates at the University of Oklahoma. In this presumed low-risk sample, 55 members reported never having previously tested for HIV antibodies. Seven members (12.7%) of the untested group were declared at risk in the course of receiving confidential computer screen advice. Of these 7, there were 3 members (42.9%) who were motivated by the computer to voluntarily seek HIV antibody testing. Of the 7 declared at risk, 2 members (3.9%) were among the 51 seronegative subjects classified as heterosexuals without specific and identified risks. All Phase II subjects seeking follow-up antibody tests were found seronegative.     

Partners of men with HIV infection and haemophilia: controlled investigation of factors associated with psychological morbidity.

The study was concerned with determining the prevalence of psychosocial problems in partners of men with haemophilia and HIV infection, and with identifying factors associated with psychological morbidity. Partners of 17 HIV positive and partners of 19 HIV negative men with haemophilia were assessed in a cross-sectional controlled investigation. Outcome measures included current psychological status and psychiatric history; coping and health beliefs; and social and sexual functioning. Partners of HIV positive men with haemophilia, the majority of whom were asymptomatic, were not found to suffer more psychological difficulties than the partners of HIV negative men with haemophilia. However, partners of haemophiliacs regardless of HIV status suffer from higher levels of psychological distress than comparable women in the community, and those with past psychiatric history and current social difficulties are particularly at risk. The sexual relationships of couples with HIV positive men were more adversely affected than those of HIV negative couples.     

Is 'knowing people with HIV/AIDS' associated with safer sex in men who have sex with men?

OBJECTIVE: To examine the sexually protective role of knowing person(s) with HIV/AIDS (PWHA) by conducting a multidimensional analysis distinguishing the number of PWHA known (by disease status and relationship category) and aspects of the relationship with the closest PWHA (emotional closeness, length of time known, disease status, type of relationship). DESIGN: Cross-sectional study of white, Latino, and African-American men who have sex with men recruited at street locations in West Hollywood, California, in 1997. METHODS: The analyses conducted with linear regression models focused on men (n = 334) who reported that they were seronegative or of unknown serostatus and thus at risk for HIV infection. Unprotected sex was defined as percentage of anal intercourse partners in the past 12 months with whom unprotected anal intercourse (UAI) occurred at least once. RESULTS: The number of PWHA known was not associated with the percentage of UAI partners in multivariate or univariate analyses. Greater emotional closeness to a person who was HIV-positive without AIDS was associated with reduced UAI in multivariate models even after excluding participants whose close PWHA was a lover or sex partner. Younger men (18-25 years) knew fewer PWHA, reported less emotional closeness to a PWHA, and had a higher level of UAI than did older men. CONCLUSIONS: Emotional closeness to a seropositive person without AIDS may be a sexually protective factor. The results suggest the possibility that lower levels of emotional closeness to a PWHA may partially underlie the elevated sexual risk behavior of younger men who have sex with men.
