Small-group HIV prevention interventions that focus on individual behavioural change have been shown to be especially effective in reducing HIV risk among persons with severe mental illness. Because economic resources to fund HIV prevention efforts are limited, health departments, community planning groups and other key decision-makers need reliable information on the cost and cost-effectiveness (not solely on effectiveness) of different HIV prevention interventions. This study used an economic evaluation technique known as cost-utility analysis to assess the cost-effectiveness of three related cognitive-behavioural HIV risk reduction interventions: a single-session, one-on-one intervention; a multi-session small-group intervention; and a multi-session small-group intervention that taught participants to act as safer sex advocates to their peers. For men, all three interventions were cost-effective, but advocacy training was the most cost-effective of the three. For women, only the single-session intervention was cost-effective. The gender differences observed here highlight the importance of focusing on gender issues when delivering HIV prevention interventions to men and women who are severely mentally ill.

Over a recent three year period, approximately 600 individuals responded to newspaper advertisements for research studies requiring healthy, cocaine using subjects. These subjects were screened using a standard phone interview in order to eliminate individuals with known medical or psychiatric illnesses that would exclude them from ongoing neuroimaging studies of drug abuse. Individuals were specifically asked about their hepatitis and HIV status. Of these, 170 subjects passed the phone screen, having no known medical or psychiatric illness outside of cocaine abuse/dependence and were willing to be further evaluated for the studies. These subjects were brought to the Medical College of Wisconsin's General Clinical Research Center and tested for, among other measures, hepatitis B, hepatitis C, and HIV. Of these, 144 completed the examination and all testing. In this cohort of assumed healthy subjects, 47 (33%) tested positive for antibodies to the hepatitis C virus (HCV). Only 7 (5%) tested positive for the hepatitis B surface antigen and 2 (1.4%) to HIV. The demographics of this cohort are 56% African-American, 81% male, 75% never-married, 55% unemployed with a mean age of 36 years. The percentage of subjects reporting any lifetime intravenous drug use among the HCV(+) and the HCV(-) cohorts was 77% vs. 29% respectively. Some routes of HCV transmission are still unclear and may reflect lifestyle or other factors related to cocaine use outside of parenteral drug use. Since almost all HCV infections become chronic, and many progress to chronic active hepatitis, cirrhosis, and ultimately hepatocellular carcinoma, these observations suggest a significant epidemic in an unsuspecting population with little regular access to health care. These individuals also form a large pool for the continued transmission of HCV to the general population. Additional public health interventions are suggested.

While adherence to antiretroviral therapy is of paramount importance in the treatment of HIV-infected patients, optimal adherence can be challenging to achieve. Furthermore, the presence of comorbid psychiatric illness can potentially compromise treatment adherence. This Case Report highlights the difficulties encountered in the care and treatment adherence of an HIV-seropositive patient who presented with psychotic symptoms. Treatment, ethical, and legal issues are discussed.

This study evaluated whether psychiatric comorbidity is related to change in HIV high risk behaviors during outpatient drug abuse treatment. Participants were opioid abusers entering methadone treatment. Psychiatric and substance use diagnoses were determined at intake. Information on HIV high risk drug use and sexual behaviors, psychosocial functioning, and urine toxicology was assessed at intake and at month six. Subjects were divided into those with versus without a lifetime comorbid non-substance use psychiatric disorder. The comorbid group reported more injection equipment sharing, lower rates of condom use, and higher rates of alcohol use at intake and follow-up. Overall injection drug use behavior decreased over the follow-up period for both groups, however. Methadone treatment had a beneficial effect on HIV risk behaviors, and though some risk behaviors improved signiticantly for both groups, comorbid subjects continued to have higher rates of HIV risk factors than noncomorbid subjects.

The authors examined the relationship between alcohol use and HIV-risk sexual behavior and tested whether alcohol use immediately prior to sex is related to decreased condom use. The participants were 159 adults living with a severe and persistent mental illness. Each participated in a structured interview to assess all sexual and drug-use behavior over a 3-month period. Analysis of 3,026 sexual behaviors reported by 123 sexually active participants indicated that at the global level, participants who drank more heavily were more likely to have engaged in sexual risk behavior. At the event level, however, alcohol use was not related to condom use during vaginal or anal intercourse; that is, participants who used condoms when sober tended to use them to the same extent when drinking.

HIV prevalence is alarmingly high among persons with serious mental illness and severely mentally ill adults frequently engage in high-risk behavior practices. This study evaluated the effectiveness of a small-group HIV risk reduction intervention offered to 189 men and women in outpatient programs for severely mentally ill adults. Participants screened for HIV risk were randomly assigned to attend either a 7-session small-group cognitive-behavioral HIV risk reduction intervention or a time-matched comparison intervention and were followed at 3-month intervals for one year. Participants who attended the HIV risk reduction intervention increased their condom use, had a higher percentage of intercourse occasions protected by condoms, and held more positive attitudes toward condoms. Women showed greater response to the intervention than men. While many behavior change effects were present at 3-, 6- and 9-month followup assessments, most diminished by the 12-month followup. These results under-score the need for tailored but ongoing HIV prevention efforts integrated into community programs that serve people with serious mental illness.

For a study designed to examine the accuracy of information about HIV transmission, risk behavior, and preventive measures among individuals with psychiatric disorders in Italy, 214 psychiatric patients-114 outpatients and 100 inpatients-and 88 nonpsychiatric patients completed the AIDS Risk Behavior Knowledge Test. Levels of knowledge were lower among psychiatric patients than among control subjects. Patients with chronic illness and a diagnosis of schizophrenia were found to have less knowledge than other patients about HIV transmission. These findings confirm the need for HIV-related educational and behavior-modification programs for patients with chronic and severe mental illness in the community in Italy.

Treatment with highly active antiretroviral therapy (HAART) decreases morbidity and mortality for persons with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and reduces costs of care. Yet many patients for whom HAART is indicated do not receive it. This study investigated the reasons why certain patients of a community health center with HIV/AIDS did not receive HAART between 1997 and 1998. Medical record reviews were performed to determine which patients for whom HAART was indicated (according to United States Public Health Service guidelines) were not prescribed HAART. Chart reviews and patient interviews were conducted to determine why they did not receive HAART. Of the 88 patients eligible for HAART, 60 (69%) had it prescribed in 1997-1998. Of the remaining 28 patients, 3 did not receive HAART because their provider never discussed it with them. For 6 patients (21%), the provider discussed HAART but did not recommend it; 16 patients (57%) declined HAART although their provider recommended it, and 3 (11%) accepted their provider's recommendation but never started HAART. Patients' most common reasons for refusing HAART were not being ready for strict adherence to a complex regimen (7/16) and fear of side effects (6/16). Other reasons included active drug use, religious beliefs, homelessness, confidentiality concerns, depression, and feeling well without HAART. Providers did not recommend HAART because of active drug use (4/6), lack of engagement with care (2/6) as well as homelessness, depression, and the perception that the patient was doing well without HAART. Providers should be trained to offer all patients the opportunity to develop a plan to address barriers to adherence and the support needed to implement it. Resources should also target the treatment of substance abuse and mental illness to improve the usage of HAART.

This study examined patterns of disclosure and psychological adjustment among mothers infected or affected by HIV. All participants were followed through a family AIDS clinic at a midwestern children's hospital. With respect to disclosure, results indicated that high perceived stress (r = 0.50, p = 0.001) and low efficacy related to managing parenting demands (r = -0.42, p = 0.01) were significantly associated with disclosure of seropositive status. Neither time since diagnosis, psychological adjustment, AIDS knowledge, nor health status as indicated by CD4 count were related to disclosure. Results also indicated that 51% of the mothers met DSM-IV diagnostic criteria for a psychological disorder in the preceding year. The most common diagnoses included posttraumatic stress disorder and major depression. Analyses suggested that perceived stress accounted for a significant 43% of the variance in psychological adjustment. Neither disclosure, time since diagnosis, nor CD4 count were related to adjustment. Findings are discussed in terms of mothers' mental health needs and provision of services to families affected by HIV/AIDS. Although the results of this study must be considered preliminary due to a limited number of participants and correlational analyses, they point to several avenues for future research.

A review of data on HIV and depression fails to show any direct cause-and-effect relationships between the two, despite the fact that clinical depression is the most commonly seen psychiatric disorder in patients with HIV infection. Most of the HIV-positive individuals with depressive disorders were found to have a history of depression antedating their infection. Contradicting early reports of unusually high rates of depression among HIV patients, more recent studies show that depression levels are not higher for the seropositive versus the seronegative, nor do the levels increase over time or at different stages of the infection. Persons with HIV may be misdiagnosed as depressed because the somatic symptoms of the illness--fatigue, lethargy, weight loss, loss of appetite, and low libido--are also symptoms of depressive disorders. Practitioners are urged to distinguish loss of interest, per se, from loss of interest in activities due to medical problems. When HIV-infected patients are diagnosed as clinically depressed, they respond as well as seronegative patients to antidepressant medications, such as tricyclic antidepressants, serotonin reuptake inhibitors (SRRI's), and psychostimulants. Brief, focused psychotherapy can prove helpful for assisting HIV-positive patients through times of particular vulnerability: the confirmation of HIV infection, adjusting to the seropositive status, onset of physical symptoms, and a sudden decline in T-cell counts.
