Tuberculosis in African Americans: clinical characteristics and outcome.

This study examined the clinical characteristics and outcome of pulmonary tuberculosis in African Americans hospitalized in a teaching hospital in south-central Los Angeles from May 1992 through April 1994. The charts of 41 African Americans with culture-positive Mycobacterium tuberculosis were reviewed. Predisposing factors for pulmonary tuberculosis were identified in nearly half of cases. Cough and fever were the most common symptoms. Seventy-six percent had positive acid-fast bacilli (AFB) smears. Nine patients were human immunodeficiency virus (HIV)-positive, and 6 of 9 HIV-positive patients had positive AFB smears whereas 17 of 19 HIV-negative patients had positive AFB smears. Radiographic changes were not significantly different between HIV-positive and HIV-negative patients. Drug resistance was identified in nine of 31 patients (29%). Eight of 41 patients (19.5%) died, with 2 being drug resistant. Human immunodeficiency virus infection was a major predisposing factor for tuberculosis, and no statistical differences were found in radiographic features or AFB smear positivity between HIV-positive and HIV-negative patients. Drug resistance and mortality were disproportionately high. These results indicate that HIV infection and drug resistance are major problems that predispose for tuberculosis infection and make its treatment difficult.     

Correlates of lending needles/syringes among HIV-seropositive injection drug users

Among HIV-positive injection drug users (IDUs), we examined the correlates of lending needles/syringes with HIV-negative and unknown status injection partners. HIV-positive IDUs (N=738) from 4 cities in the United States who reported injection drug use with other IDUs in the past 3 months participated in an audio computer-assisted self-administered interview. Eighteen percent of study participants self-reported having lent their needles to HIV-negative or unknown status injection partners. Multivariate analyses showed that 6 variables were significantly associated with this high-risk injecting practice. Older IDUs, high school graduates, and those reporting more supportive peer norms for safer drug use were less likely to lend needles/syringes. Admission to a hospital for drug treatment in the past 6 months, having injected with >1 person in the past 3 months, and having more psychiatric symptoms were all associated with more risk. These findings underscore the need for a continued prevention focus on HIV-positive IDUs that recognizes the combination of drug use, mental health factors, and social factors that might affect this high-risk injecting practice, which could be associated with HIV and hepatitis C transmission.     

Mortality of HIV-positive and HIV-negative heroin abusers as a function of duration of injecting drug use

OBJECTIVE: To determine the incidence of mortality of injecting drug users as a function of the duration of injecting drugs and HIV status, and to assess how these effects vary according to age at initiation and calendar period (before and after 1992). METHODS AND DESIGN: Cohort of 376 intravenous heroin users admitted to detoxification between February 1987 and January 1990. SETTING: Patients referred from outpatient clinics of metropolitan Barcelona. Duration and characteristics of drug use were determined by interviews. Blood samples were collected during admission and analyzed for HIV, CD4+ cell count and different biologic parameters. Assessment of vital status and causes of death were obtained by hospital charts, death certificates, and autopsies. RESULTS: The study population consisted of 299 men and 77 women, whose mean age at entry was 26 years, mean duration of injecting drug use before admission 6.1 years; HIV seroprevalence at entry 70.2%. By the end of the follow-up (median 5.6 years), 21.8% of individuals had died (26.6% in HIV-positive, and 10.7% in HIV-negative injecting users). Based on Kaplan-Meier estimates, 10%, 20%, and 30% of HIV negative patients died by 8.7, 11.3 and 14.3 years, respectively, after initiating injecting drugs. The corresponding survival times for the seropositives were substantially lower: 6.6, 8.5, and 11.6 years, respectively. Overall, the survival time was significantly (p < .05) decreased by 22% in HIV-positive injecting drug users. Older age at initiation of injecting drug use was significantly (p < .05) associated with mortality in HIV-positive heroin users but it showed the opposite direction among HIV-negative people. Death rates in HIV-positive patients of the same duration of drug use were similar in periods before and after 1992 (relative hazard (RH) = 0.97; 95% confidence interval: 0.58-1.61). Although not statistically significant, the hazard of death in HIV-negative injecting drug users was substantially lower after 1992 (RH = 0.59). CONCLUSIONS: Before introduction of potent antiretroviral therapies, HIV infection further increased rates of mortality that had already been heightened by injecting drug use. Furthermore, HIV infection modifies the effect of age at initiation and eliminates the seemingly downward trend of mortality in HIV-negative people.     

Self-reported psychiatric symptoms among black, Hispanic, and white outpatients

Examined ethnic differences among black, Hispanic, and white applicants for outpatient psychotherapy, using symptoms self-reported on the Symptom Checklist 90-Revised (SCL 90-R). The relationship between self-reported severity of symptoms and therapist-reported severity of psychiatric diagnoses also was examined in order to assess the utility of SCL 90-R as a predictor of diagnostic severity for these ethnic groups. One hundred sixty-five patients completed the SCL 90-R. The patients were predominantly in the low-income social classes. A significant ethnic effect was found on several symptom dimensions, with black patients less likely to report symptoms than Hispanic or white patients. Hispanic patients were found to report the highest symptom levels on 8 of 11 measures. While, overall, therapist diagnostic severity was related significantly to self-reported symptomatology, the relationship was strongest for white patients, significant but less strong for Hispanic patients, and not significant for black patients.     

Determinants of emotional distress in women with polycystic ovary syndrome

BACKGROUND: The goals were to analyse the incidence of mental distress in women with untreated polycystic ovary syndrome (PCOS) using self-report measures, to characterize PCOS patients at risk for psychiatric disease with regard to sociodemographic and clinical characteristics, and to assess the impact of emotional distress on quality of life. METHODS AND RESULTS: Complete metabolic, hormonal, clinical and self-report psychological data [emotional distress, Symptom Check List 90 (SCL-90-R); quality of life, Short-Form Health Survey 36 (SF-36); sexual satisfaction, visual analogue scales; sociodemographic data] were obtained from n = 143 untreated women with PCOS. Prior psychiatric diagnoses were exclusionary. Twenty-two patients (15.4%) had a possible psychological disorder, based on SCL-90-R global severity index (GSI) scores > or =63 (SCL cases). SCL cases had significantly elevated body mass index (BMI), but did not differ from SCL non-cases in other clinical, endocrine, metabolic or sociodemographic variables. Stepwise multiple regression analyses identified GSI as a significant predictor of SF-36 Psychological Sum score, along with age and current wish to conceive (R2 = 0.47); the SF-36 Physical Sum score was predicted by BMI and education (R2 = 0.27), but not GSI. CONCLUSIONS: Psychiatric illness may go undetected in a proportion of PCOS patients. Although the majority of patients exhibit subclinical levels of psychological disturbances, emotional distress together with obesity lead to large decrements in quality of life in PCOS.     

Neuropsychological functioning in HIV-positive African-American women with a history of drug use.

This preliminary investigation examined neuropsychological performance in a sample of human immunodeficiency virus (HIV)-positive and HIV-negative African-American women with a history of drug use. The study population was comprised of 10 HIV-negative, 9 asymptomatic HIV-positive, 13 symptomatic HIV-positive, and 10 acquired immunodeficiency virus (AIDS) patients. A neuropsychological battery designed to assess attention, psychomotor processing, verbal memory, and visual memory was administered to participants. No evidence of HIV-related cognitive impairment was found in patients in the early stages of HIV infection. Multivariate analyses of variance revealed significant deficits in psychomotor processing and verbal recall in persons with AIDS. These individuals showed greater difficulty in tasks requiring maintained attention and performed poorly on measures of immediate and delayed verbal recall. In contrast, HIV status was not related to visual memory, verbal recognition, or the number of errors made during a verbal recall task. The pattern of cognitive deficits observed in persons with AIDS resembles that commonly associated with subcortical pathology. The cognitive deficits observed were not related to depression or recentness of drug use.     

The impact of sex partners' HIV status on HIV seroconversion in a prospective cohort of injection drug users

OBJECTIVE AND DESIGN: The identification of individuals at highest risk of HIV infection is critical for targeting prevention strategies. We evaluated the HIV status of the sex partners of injection drug users (IDUs) and rates of subsequent HIV seroconversion among a prospective cohort study of IDUs. METHODS: We performed an analysis of the time to HIV infection among baseline HIV-negative IDUs enrolled in the Vancouver Injection Drug Users Study. IDUs were stratified based on whether or not they reported having an HIV-positive sex partner. Kaplan-Meier methods were used to estimate cumulative HIV incidence rates, and Cox regression was used to determine adjusted relative hazards (RHs) for HIV seroconversion. RESULTS: Of 1013 initially HIV-negative IDUs, 4.8% had an HIV-positive partner at baseline. After 18 months, the cumulative HIV incidence rate was significantly elevated among those who reported having an HIV-positive sex partner (23.4% vs. 8.1%; log-rank P < 0.001). In a Cox regression model adjusting for all variables that were associated with the time to HIV infection in univariate analyses, including drug use characteristics, having an HIV-positive sex partner (RH = 2.42 [95% confidence interval: 1.30 to 4.60]; P = 0.005) remained independently associated with time to HIV seroconversion. CONCLUSIONS: Having an HIV-positive sex partner was strongly and independently associated with seroconversion after adjustment for risk factors related to drug use. Our findings may aid public health workers in their efforts to identify IDUs who should be targeted with education and prevention efforts and indicate the need for ongoing development of prevention interventions for IDU sex partners who are HIV discordant.     

HIV infection affects parietal-dependent spatial cognition: evidence from mental rotation and hierarchical pattern perception

Human immunodeficiency virus (HIV) in the asymptomatic phase of the infection impairs some aspects of cognition, but little is known about how visuospatial functions are affected. In the present study, performance on tasks of mental rotation and hierarchical pattern perception was investigated in 14 HIV-positive men and 12 age- and education-matched HIV-negative men. Processes related to mental rotation of objects and hands were impaired in HIV-positive participants as compared to the HIV-negative group. The HIV-positive group was also impaired on hierarchical pattern perception of local targets under global biasing conditions. Consistent with these results, the HIV-positive participants showed impaired performance on standard clinical neuropsychological tests of visuospatial function. These findings indicate that the detrimental effects of HIV on cognition appear even in asymptomatic individuals and affect diverse visuospatial functions that depend upon the integrity of parietal brain regions.     

Human immunodeficiency virus-related risk behavior among African-American females

This study draws attention to the demographic shift in the population of HIV-infected African Americans from young, low-income, unmarried homosexual, and injecting drug users to female, heterosexual, higher income, and older persons. We used data from the 1995 Survey of Family Growth, sponsored by the National Center for Health Statistics, to examine the patterns of HIV-related risk behavior (consistent condom use, number of sexual partners, sex education in birth control methods) among African-American females. We found that only 33.3% of the African-American females had indicated that their partners always used condoms; 23.8% had seven or more lifetime sexual partners; and nearly 30% did not have any sex education in birth control methods, sexually transmitted diseases, or abstinence. In addition, African-American females who had partners who had not used condoms in the last 12 months were less likely than those who reported occasional condom use to perceive that they were infected with HIV (21.1% vs. 33.1%). These risk factors were prevalent among low-income African-American females with low socioeconomic status (SES) as well as black women with higher SES who lived in smaller cities and suburbs. These results highlight the need for HIV prevention strategies that cut across socioeconomic class, gender, sexual orientation, and place of residence.     

EVALUATION OF OUTCOME IN A DYNAMICALLY ORIENTATED GROUP FOR ADULT MALES WHO HAVE BEEN SEXUALLY ABUSED IN CHILDHOOD

ABSTRACT At a time when males abused in childhood are coming increasingly to attention of clinical services, we review the literature, describe the process and report on clinical outcomes of a slow open long-term dynamically orientated group for abused adult males. Twenty-nine men referred to the local psychotherapy service for consideration for inclusion in the group are discussed along with some of the most prevailing themes, namely identification with the aggressor, self-esteem, guilt and sexuality. Symptoms were measured using the SCL 90-R and demonstrate relatively high levels of psychological distress in this group at initial assessment. There is significant improvement in global scores, interpersonal sensitivity, depression and psychoticism in the group of 13 men who engaged in therapy for at least six months compared with those who did not.
The authors conclude that symptom measurement provides evidence that group psychotherapy is a useful therapeutic approach in a group of men who might otherwise be considered unsuitable for psychotherapeutic interventions due to symptom severity and personality difficulties.     

Natural history of HIV-1 infection and predictors of survival in a cohort of HIV-1 seropositive injecting drug users.

Injecting drug users represent a pivotal and increasing component of acquired immunodeficiency syndrome (AIDS) case reporting in the United States. This article describes the natural history of human immunodeficiency virus (HIV) disease in a New York City cohort of 328 HIV-infected injecting drug users. The study sample of nearly two-thirds men (predominately African Americans and Latino Americans) underwent follow-up from December 1988 through December 1993. Male injecting drug users reported a longer injecting drug use history and were more likely to share needles/works than female injecting drug users. Eighty-nine of 328 study subjects died during the 5 years of observation. Comparing African Americans and Latinos, race/ethnicity was not related to survival. Survival was related to baseline CD4 count and hemoglobin level. Zidovudine use and PCP prophylaxis did not predict survival. Because of the continuing and increasing impact of HIV disease on injecting drug users and communities of color, there remains an unquestionable need to develop effective prevention programs, to understand the natural history of HIV disease, and to develop appropriate therapeutic interventions to treat those with HIV disease.     

Anti-cardiolipin antibodies and HIV infection

Anti-cardiolipin antibodies of IgG class were found in 48% of intravenous drug users, 38% of homosexuals and 14% of heterosexuals (with no other risk factor) infected with HIV. Anti-cardiolipin antibodies were not increased in HIV-negative heterosexual partners of HIV-infected patients, but mildly elevated levels were detected in HIV-negative drug users, relative to healthy controls unselected for HIV status. Among HIV infected drug users, anti-cardiolipin antibodies were not associated with thrombocytopenia, Pneumocystis carinii pneumonia, disease progression or clinical stage. Anti-cardiolipin antibodies appear to be another non-specific marker of HIV infection which may be particularly common in male intravenous drug users infected with the virus.     

Immunoglobulin levels amongst persons with and without human immunodeficiency virus type 1 infection in Uganda and Norway

CD4+-cell count and viral load monitoring are expensive and unavailable to most human immunodeficiency virus (HIV)-infected people in Africa. In an attempt to evaluate alternative methods for monitoring antiretroviral (ARV) therapy, we measured concentrations of immunoglobulin (Ig)A, IgM, IgG and IgG1 amongst adults with and without HIV in Uganda and Norway. We adjusted for disease severity by stratifying HIV-positive subjects on CD4+-cell counts above and below 200 cells/ micro l. Median serum levels of IgG, IgG1 and IgA were significantly higher in HIV-positive persons compared with HIV-negative persons in both countries (P < 0.001 and P = 0.018 for IgA in Ugandan patients). Levels of IgA in Ugandan HIV-negative subjects were significantly lower than those in HIV-positive subjects with low CD4+ compared with those with high CD4+-cell counts (P < 0.001 and P = 0.069, respectively). IgM levels were different between the HIV-negative and the two HIV-positive groups in Norway (P < 0.001). The mean levels of IgM, IgG and IgG1 in HIV-negative and -positive African subjects were generally higher than those in comparable groups of Western subjects. Our results verify that levels of IgA, IgG and IgG1 vary between HIV-negative and -positive individuals in both study populations. Their determination may be useful in monitoring both disease progression and response to ARV therapy.     

What is the significance of black-white differences in risky sexual behavior?

A sample of African-American and white young adults were classified as having multiple sex partners or one sexual partner. Subjects with multiple sexual partners were more likely to use drugs and practice risky sexual behaviors such as having anal intercourse, having sexual experiences with a prostitute, and having a history of gonorrhea (P < .001) and genital warts (P < .01). Additional analyses were conducted to determine African-American versus white differences in risky sexual behaviors. Results indicated that whites in the multiple partners and single partner groups were more likely to engage in anal and oral sex, while African Americans were more likely to have sex with prostitutes. Attitudes about the use of condoms differed significantly by multiple partner status (P < .004) and gender (P < .007), but not ethnicity. However, angry reactions about the use of condoms occurred more with African Americans (P < .003) and males (P < .05) than with whites or females. While whites reported a greater use of drugs and a significantly higher level of knowledge about HIV/AIDS, African Americans reported a significantly greater perception of risk for being exposed to human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (P < .01) and significantly more gonorrhea (P < .10), syphilis (P < .05), and HIV/AIDS (P < .05). No whites in our sample were treated for syphilis nor had they tested positive for HIV/AIDS. On the other hand, 4.5% of the total sample of African Americans reported testing positive for HIV/AIDS. Finally, the results from discriminant analysis indicate that a large number of variables significantly discriminate between subjects who engage in risky sexual behaviors and those who do not. Although there is some similarity in the variables for African Americans and whites, there was tremendous variability between the ethnic groups in the factors that predict risky behaviors. These findings are discussed with reference to the need to develop HIV/AIDS prevention programs for African Americans that are based on data derived from African-American populations rather than from black versus white comparison studies.     

Psychological distress among women suffering from couple infertility in South Africa: a quantitative assessment

BACKGROUND: Infertility in Africa is commonly associated with negative psycho-social consequences. To date, most studies from African countries addressing these consequences have been qualitative in nature. The aim of this study was to assess psychological distress quantitatively among women suffering from couple infertility in an urban community in South Africa. METHODS: The Symptom Checklist-90-R (SCL-90-R), a standardized instrument for the measurement of current psychological symptom status, was administered to 120 women at the time of their first presentation to an infertility clinic in a tertiary referral centre. The control group comprised 120 women presenting to local family planning clinics. In addition, socio-demographic information and data pertaining to the prevalence of abuse was captured through a structured questionnaire designed for the purpose of this study. RESULTS: Women suffering from involuntary childlessness scored significantly higher on all sub-scales and the global indices of distress of the SCL-90-R when compared to controls. In addition, women who reported abuse from their male partners had significantly higher scores on six of the 12 test scales when compared to infertile women in non-abusive relationships. CONCLUSIONS: Involuntary childlessness is associated with high levels of psychological distress. Women in abusive relationships are particularly at risk. This result is in keeping with several qualitative studies from African countries which describe infertility as an overwhelmingly negative and distressing experience. Cognizance needs to be taken of these experiences and effective interventions require medical, psychological and socio-cultural strategies.     

Discussion of HIV status by serostatus and partnership sexual risk among internet-using MSM in the United States

Men who have sex with men (MSM), particularly black MSM, are disproportionally infected with HIV. Little is known about how discussion of HIV status between partners varies among MSM by race/ethnicity and by HIV transmission risk. Among a national survey of 2031 MSM reporting 5410 partnerships, black MSM, especially black HIV-positive MSM, serodiscussed with unprotected anal intercourse partners less than did white MSM. Although non-black HIV-positive, non-black HIV-negative MSM, and black HIV-negative MSM were more likely to report serodiscussion with unprotected anal intercourse partners, black HIV-positive MSM were not. Differential serodiscussion may play a role in explaining the racial/ethnic disparity in HIV incidence.     

Intimate partner violence perpetration against main female partners among HIV-positive male injection drug users

Intimate partner violence (IPV) against women is a serious public health and social problem and is associated with a host of adverse health outcomes and behaviors, HIV risk behaviors included, among women who are victimized. Historically, research has focused on correlates of IPV victimization among women; thus, there is less information on the role of men in perpetrating IPV, particularly among men at risk for transmitting HIV to their female partners. We assessed the self-reported prevalence and correlates of perpetration and threat of perpetration of physical and/or sexual IPV against a main female partner among 317 HIV-positive men who were current injection drug users (IDUs). More than 40% of men reported perpetrating physical (39%) and/or sexual (4%) violence against their main female partners in the past year. Multivariate analyses revealed that low education, homelessness, psychologic distress, and unprotected sex with main and nonmain HIV-negative female partners were positively associated with IPV perpetration against main female partners. These findings reveal that IPV perpetration is prevalent among HIV-positive male IDUs and associated with sexual HIV transmission risk behaviors. IPV assessment and treatment among HIV-positive men in HIV care is recommended as a way to prevent IPV perpetration and victimization and to reduce potential HIV transmission.     

Combination therapies for HIV and sexual risk behavior among gay men

OBJECTIVE: To examine optimism in the light of recent advances in HIV treatment among gay men and its association with sexual risk behavior. METHODS: An anonymous questionnaire was completed by gay men who visited gyms in central London in March and April 1998 regarding their HIV status, unprotected anal intercourse (UAI) in the previous 3 months, and their response on a five-point linear scale to two measures of optimism: "I am less worried about HIV now that treatments have improved," and "I believe that new drug therapies make people with HIV less infectious." RESULTS: Two thirds of the men (67.5%, 522 of 773) did not agree with the statement, "I am less worried about HIV now that treatments have improved," and only 42 (5.4%) said they agreed quite a lot or a lot. HIV-positive men were more likely to agree with this statement than HIV-negative men (p = .001) and men who had never been tested (p < .001). There was no association between agreement with this statement and frequency of UAI among HIV-positive or never-tested men (p > .3); there was, however, a positive association among HIV-negative men who reported UAI with a partner of unknown or discordant status (p = .003). The vast majority of men (81.4%; 634 of 779) did not agree with the statement, "I believe that new drug therapies make people with HIV less infectious." Regardless of HIV status, no significant association was seen between agreement with this statement and frequency of UAI (p > .1 for all comparisons). CONCLUSION: Most gay men surveyed in central London gyms did not endorse the optimism statements concerning improved treatments or reduced infectivity. Although HIV-positive gay men were more likely to be optimistic than other men, there was no association between their optimism and sexual risk behavior. Among HIV-negative men, optimism around improved treatments (but not around reduced infectivity) was associated with UAI with a partner of unknown or discordant HIV status. For some HIV-negative men in London, optimism in the light of recent advances in HIV treatment may have triggered, or have been used as a justification for, sexual risk-taking.
