Recent data suggest that the homeless and those with chronic mental illness may be at increased risk for HIV infection. A review of the recent literature reveals insufficient rigorously collected data to identify with confidence any particular subgroup of chronically mentally ill patients at increased risk. Nonetheless, it seems reasonable to suspect that those with acute psychosis, a history of substance abuse, or a history of sexual abuse may be at higher risk. Conversely, some data currently support the conclusion that homeless persons are at increased risk for infection due to human immunodeficiency virus (HIV). Clinicians of all disciplines should be aware of these findings and be particularly vigilant when patients are members of both aforementioned groups. Future research should focus upon improving service delivery to the homeless and mentally ill, particularly with regard to sex education and substance abuse intervention. Also, continued research into causal influences of homelessness will ultimately lead to more definitive intervention.

The relationship between psychological problems and human immunodeficiency virus HIV/AIDS risk-taking behaviors was examined among 834 daily opioid users entering methadone treatment programs. A composite measure of psychological dysfunction was created using depression, anxiety, and hostility scales. This measure was found to be significantly related to needle risk in terms of injecting with used equipment, sharing of drug paraphernalia, and sharing with strangers. Psychological dysfunction was also related to sexual risk taking in terms of number of partners, unprotected sex with other injection drug users, and trading sex. Use of cocaine was significantly related to all measures of injection and sex-related risk taking; use of speedball (heroin and cocaine) was significantly related to use of dirty equipment and sharing of paraphernalia. The implications of study findings for AIDS prevention programming are discussed.

There is very little published information regarding the co-occurrence of human immunodeficiency virus (HIV)-spectrum illness and psychotic illnesses, including schizophrenia, even though their coexistence in the same patient may severely affect the course of both illnesses. Estimates of the frequency of HIV infection in patients with preexisting mental illness range between 5 and 7 percent. Estimates of new-onset psychosis in patients with HIV-spectrum illness range between 0.2 and 15 percent and may increase as the stage of HIV illness progresses. Regardless of which illness came first, their occurrence together appears to be associated with more morbidity and mortality than would be expected with either illness alone. Patients with new-onset psychosis respond to and tolerate relatively low doses of antipsychotic medication. Whether the presence of HIV decreases the effective daily dose of neuroleptic medication in patients with preexisting psychosis is not yet known. A clearly superior neuroleptic medication for patients with both psychosis and HIV infection has not yet been identified. Further systematic exploration is needed.

Behaviors associated with transmission of the human immunodeficiency virus (HIV) were measured in a sample of 60 adults with a severe and persistent mental illness (SPMI). Results revealed that 68% had sex in the last year; 13% of men and 30% of women reported two or more male partners, and 24% of men also reported two or more female partners. Condom use was inconsistent. Sex partners were often met in a psychiatric clinic or bar, and a substantial number were injection drug users or known to be non-monogamous. Overall, 48% of men and 37% of women reported at least one risk factor. Hypothesized psychological antecedents of HIV-related risk behavior were also measured, including knowledge, motivation for risk reduction, and self-efficacy regarding risk-reduction. Many participants were misinformed regarding HIV-transmission and risk reduction. Motivational indices indicated that attitudes toward condoms were slightly positive, and that social norms were generally supportive of condom use. However, participants tended to rate themselves at only slight risk for infection, undermining their motivation for condom use. Participants indicated only modest levels of self-efficacy in situations requiring sexual assertiveness. These findings, coupled with the elevated seroprevalence of HIV among persons having a SPMI, point to the need for risk assessment and counseling by mental health care providers.

Individuals diagnosed with a severe mental illness are at significantly enhanced risk for infection with the human immunodeficiency virus (HIV). To better understand elevated seroprevalence in this population, we review the research literature that has investigated HIV-related risk behavior among adults who have a severe and persistent mental illness. This review indicates that 54%-74% of adults report that they have been sexually active in the last year with approximately one third reporting two or more partners. Among those who were sexually active, condom use was inconsistent. A significant minority (4%-35%) of adults also reported a history of injection drug use. Overall, the data indicate that the severely mentally ill engage regularly in practices known to involve increased risk for HIV transmission. We introduce and modify Fisher and Fisher's (1992) theoretical model to organize the possible determinants of HIV-related risk taking among severely mentally ill adults, and encourage use of this model in the design of behavioral epidemiological and risk reduction studies. We also identify several methodological challenges to HIV-related research, including problems associated with the use of self-report measures; diagnostic imprecision; and participant recruitment and retention.

It is now established that very significant numbers of people with severe mental illness abuse or depend on drugs and/or alcohol. This combination (Dual Diagnosis) leads to increased rates of violence and service use, a reduction in adherence to treatment regimes, an increase in susceptibility to human immunodeficiency virus (HIV) infection and is now found in in-patient populations. Because of their vulnerability to accidents and physical illnesses, dual diagnosis patients are found increasingly in accident and emergency departments, general medical wards and primary care settings. For this reason nurses and other health professionals working in general hospitals should be as aware as their mental health colleagues of the specific needs of this population. There are some excellent models of service organization and training for dealing with dual diagnoses populations in some parts of the USA. However, there is little such development in the UK. There are clear pathways to be followed, but the need for action is urgent.

Seldom in the history of medicine has an entire generation of patients with an incurable, progressive, and ultimately fatal disease suddenly been offered the prospect of extended survival and even, perhaps, a "second life." The relatively simultaneous appearance of 2 major treatment developments has created profound changes in therapeutic options and outlook. The first development is an assay of serum levels of human immunodeficiency virus viral copies, providing a critical tool for clinical decision making. The second is the marketing between December 1995 and April 1997 of 4 human immunodeficiency virus protease inhibitors that, combined with previously available antiviral medications, achieve a new level of efficacy. With the advent of these changes come multiple psychiatric research and policy issues. These include the development of strategies to establish and maintain medication adherence. This is a critical task, given the complexity of combination therapy regimens and the rapid onset of viral resistance to protease inhibitors within days to weeks of missed or suboptimal dosing. The psychological issues to be studied include the process of restructuring lives and expectations in the event of clinical benefit or managing the distress associated with clinical failure. Other research questions include the effects of restored health on the appraisal of human immunodeficiency virus risk behaviors, assessment of effect of neurocognitive functioning, and unanswered questions about psychotropic or protease inhibitor drug interactions due to their shared metabolic pathways. Behavioral scientists can inform provision of care to patients who may be considered difficult to treat, such as those with severe and persistent mental illness or active substance abuse or the homeless. This includes the provision of empirical data regarding individual and situational characteristics that are likely to promote or impede adherence, as well as innovative provision systems. Psychiatry can make notable contributions during this turning point in human immunodeficiency virus therapeutics and research.

The aim of this study was to verify the suitability of antituberculosis (antiTB) drug-resistance surveillance as a tool for tuberculosis (TB) control programmes at local level. A retrospective study reviewing laboratory records and medical records of TB patients referred to Udine Hospital between 1981 and 1995 was analysed. The initial susceptibility pattern for each Mycobacterium tuberculosis isolate was recorded. It was found that between 1981 and 1995, 899 M. tuberculosis strains underwent susceptibility testing for four first-line drugs. Over a period of 15 yrs the annual number of M. tuberculosis strains initially decreased and then stabilized. Overall, 15.3% of the 899 strains showed initial resistance to at least one first-line drug, and 2.8% to two or more first-line drugs. Streptomycin-resistant strains were the most commonly observed (10.8%), with resistance to isoniazid, rifampicin and ethambutal shown to be 6.4, 1.0 and 0.4%, respectively. Multidrug resistant (MDR)-TB was observed in only five cases. An additional four cases eventually developed secondary MDR-TB during the follow-up. The proportion of resistant strains did not vary significantly over time. Recurrent TB disease was significantly associated with resistant strains (odds ratio = 3.59, p < 0.01). Only one patient had a documented human immunodeficiency virus (HIV)-positive serology. All six patients who developed MDR-TB during or after treatment, were suffering either from chronic alcoholism or from a psychotic disorder. In the study it was shown that recurrent tuberculosis cases, tuberculosis patients with behavioural problems (i.e. alcoholism, psychiatric disorder) and patients presenting with primary resistant Mycobacterium tuberculosis strains are at risk of multidrug-resistant tuberculosis and may thus benefit from the directly observed treatment approach, which has been proposed as a mainstay in tuberculosis control programme strategy.

A cross-sectional study was performed to investigate the prevalence and predictors of suicidal ideation and past suicide attempt in an Australian sample of human immunodeficiency virus (HIV)-positive and HIV-negative homosexual and bisexual men. Sixty-five HIV-negative and 164 HIV-positive men participated. A suicidal ideation score was derived from using five items selected from the Beck Depression Inventory and the General Health Questionnaire (28-item version). Lifetime and current prevalence rates of psychiatric disorder were evaluated with the Diagnostic Interview Schedule Version-III-R. The HIV-positive (Centers for Disease Control and Prevention [CDC] Stage IV) men (n = 85) had significantly higher total suicidal ideation scores than the asymptomatic HIV-positive men (CDC Stage II/III) (n = 79) and the HIV-negative men. High rates of past suicide attempt were detected in the HIV-negative (29%) and HIV-positive men (21%). Factors associated with suicidal ideation included being HIV-positive, the presence of current psychiatric disorder, higher neuroticism scores, external locus of control, and current unemployment. In the HIV-positive group analyzed separately, higher suicidal ideation was discriminated by the adjustment to HIV diagnosis (greater hopelessness and lower fighting spirit), disease factors (greater number of current acquired immunodeficiency syndrome [AIDS]-related conditions), and background variables (neuroticism). Significant predictors of a past attempted suicide were a positive lifetime history of psychiatric disorder (particularly depression diagnoses), a lifetime history of infection drug use, and a family history of suicide attempts. The findings indicate increased levels of suicidal ideation in symptomatic HIV-positive men and highlight the role that multiple psychosocial factors associated with suicidal ideation and attempted suicide play in this population.

A longitudinal study was conducted to investigate the association between human immunodeficiency virus (HIV) infection, history of major depressive disorder (MDD), and persistent or recurrent MDD among intravenous drug users. Psychiatric disorders were assessed in a sample of HIV-positive (HIV+) and HIV-negative (HIV-) intravenous drug users every 6 months for 3 years. Results indicated that HIV status and baseline MDD independently predicted persistent or recurrent episodes of MDD after gender, drug use, ethnicity, income, and the presence other psychiatric disorders were controlled statistically. Among HIV+ intravenous drug users with baseline MDD, 90% experienced at least one subsequent episode of MDD and 47% experienced at least three subsequent episodes of MDD. However, less than 40% of intravenous drug users with current MDD received treatment for emotional problems. These findings indicate that intravenous drug users with HIV infection and a history of MDD are at considerable risk for future episodes of MDD or recurrent MDD, and that increased provision of treatment for intravenous drug users with MDD may be necessary.
