Psychological adjustment in caregivers of school-age children infected with HIV: stress, coping, and family factors.

OBJECTIVE: To assess for significant differences in psychological functioning between caregivers of HIV-infected children and caregivers of healthy children, and to examine the utility of applying a stress and coping model to caregivers of children with HIV disease. METHODS: Participants included caregivers of HIV-infected children (n = 36) and caregivers of a demographically matched control group of healthy children (n = 32). During their child's pediatric clinic visits, caregivers completed measures of psychological adjustment, stress, coping style, and family resources and support. They also completed a measure of their child's psychological adjustment. RESULTS: Caregiver psychological distress scores did not significantly differ between the HIV and control groups, and clinically significant rates of psychological distress were reported by more than a third of caregivers in both groups. Hierarchical multiple regression analyses revealed that independent of their child's illness status, stress and coping style were significant predictors of caregiver's psychological adjustment. In addition, caregiver psychological distress was a significant predictor of children's maladjustment. CONCLUSIONS: High rates of psychological distress were observed in caregivers of children with HIV disease; however, similarly high rates of psychological adjustment problems were found in caregivers of healthy children. Caregivers who reported high levels of daily stress and emotion-focused coping styles tended to report more psychological distress. Further, caregivers who reported more psychological distress also reported more internalizing and more externalizing behavior problems in their children, regardless of the child's illness status. These findings reflect the impact of poverty and environmental stress on caregivers' adjustment.

Predictors of psychological adjustment in school-age children infected with HIV.

OBJECTIVE: To assess for significant differences in psychological functioning between HIV-infected children and a demographically matched healthy control group and to examine the utility of applying a stress and coping model to children with HIV disease. METHODS: Participants included HIV-infected children (ages 6-16) and their caregivers (n = 36) and a control group of healthy children and their caregivers (n = 32). During routine clinic visits, children completed measures of psychological adjustment, health locus of control, and coping style, and caregivers completed measures of their own and their child's psychological adjustment. RESULTS: Caregiver-reported and child self-reported psychological adjustment scores did not significantly differ between the HIV and control groups, with the exception of significantly more internalizing behavior problems reported in the control group. Hierarchical multiple regression analyses revealed that the stress and coping model accounted for 36% of the variance in HIV-infected children's self-reported psychological adjustment. In addition, child age and coping style were significant predictors of child self-reported psychological adjustment, but not of caregiver-reported child adjustment. CONCLUSIONS: Approximately 25% of children with HIV disease exhibited clinically significant emotional or behavioral problems; however, even higher rates of psychological adjustment problems were found in healthy children. Children with HIV disease who have not been told their diagnosis and children who endorse more emotion-focused coping strategies tend to exhibit more psychological adjustment problems.

Higher than normal plasma interleukin-6 concentrations in cancer patients with depression: preliminary findings.

OBJECTIVE: This study investigated whether cancer patients with and without major depression exhibit immune system abnormalities similar to those reported in medically healthy, depressed subjects without cancer. METHOD: The study subjects consisted of patients diagnosed with pancreatic, esophageal, or breast cancer. Other groups consisted of subjects with major depression (without cancer) and healthy comparison subjects. Subjects' diagnoses were made with the Structured Clinical Interview for DSM-III-R. Severity of depression was measured with the Hamilton Depression Rating Scale. Plasma concentrations of interleukin-6 (IL-6) and postdexamethasone cortisol were measured. RESULTS: Cancer patients with depression had markedly higher plasma concentrations of IL-6 than healthy comparison subjects and cancer patients without depression. Although significant correlations were found between Hamilton depression scale scores and plasma concentrations of postdexamethasone cortisol, no significant correlations were found between plasma IL-6 and postdexamethasone cortisol concentrations. CONCLUSIONS: Higher than normal plasma IL-6 concentrations were associated with a diagnosis of major depression in cancer patients. IL-6 may contribute to sickness behavior that has overlapping symptoms with major depression.

Double-blind comparison of fluoxetine and desipramine in the treatment of depressed women with advanced HIV disease: a pilot study.

A double-blind, placebo-controlled study was conducted to assess the relative efficacy and tolerability of fluoxetine and desipramine in depressed, human immunodeficiency virus (HIV)-positive women. Although difficulty in the recruitment and retention of participants led to insufficient power to detect differences between treatment groups, results indicated that participants experienced improvement in their depression. However, for most women, significant depressive symptoms remained after 6 weeks of treatment. In addition, although most participants reported at least one adverse event after treatment began, most of the side effects, regardless of treatment condition, were mild to moderate in severity. Important barriers to study participation and completion are discussed, as well as suggestions for increasing the involvement of depressed, HIV-positive women in future treatment studies.

Severe mental illness and HIV-related medical and neuropsychiatric sequelae.

Medical and neuropsychiatric sequelae of HIV infection present a spectrum of diagnostic and treatment challenges to mental health clinicians. Both HIV and the many opportunistic infections that manifest in patients due to their immunocompromised state also can affect the central nervous system (CNS). Thus, mental health clinicians need to be familiar with the diagnosis and management of HIV-related medical and psychiatric complications. This article provides an overview of the CNS-related manifestations resulting from HIV disease, including HIV-related dementia, psychotic disorders, delirium, CNS opportunistic infections and tumors, systemic abnormalities, psychoactive substances, and the adverse effects of certain medical treatments. Treatment strategies for individuals with HIV disease and comorbid severe mental illness are outlined and recommendations for future research are offered.

Depression in patients with cancer. Diagnosis, biology, and treatment.

This article reviews the challenge of diagnosing depression in patients with cancer. Major depression and depressive symptoms, although commonly encountered in medical populations, are frequently underdiagnosed and undertreated. This is especially true for patients with cancer in whom the diagnosis of major depression is clouded by neurovegetative symptoms that may be secondary to either cancer or depression. Well-established biological markers for major depression are proposed as diagnostic adjuncts in patients with cancer. Studies using biological markers in depressed patients with and without cancer are reviewed, and the implications of diminished immune function in depressed patients with cancer are discussed. The limited database on treatment of depression in patients with cancer also is reviewed. Treatment of depression in these patients improves their dysphoria and other signs and symptoms of depression, improves quality of life, and may improve immune function and survival time. Guidelines for future research are proposed.

An assessment of rates of psychiatric morbidity and functioning in HIV disease.

This study examined demography, rates of psychopathology, and functional impairment in HIV-seropositive women and men in a large, urban, public outpatient infectious disease clinic. Fifty-three percent of the women and 70% of the men met Structural Clinical Interview for DSM-III-R criteria for psychiatric disorders. Current mood disorders were the most frequent diagnoses, followed by psychoactive substance abuse/dependence disorders and psychotic disorders. Seventy-six percent of the women and 90% of the men had previous psychiatric histories, including 59% of the women and 55% of the men who had psychiatric histories prior to their knowledge of HIV seroconversion. Depressed subjects reported significant impairment in physical, social, and role functioning. Similarly, impairment in physical functioning was highly correlated with self-reported anxiety symptoms. These data suggest considerable past and current psychiatric comorbidity in HIV-infected individuals seeking medical care, and draw attention to the need for recognition and aggressive psychiatric treatment, particularly for those depressed and anxious patients with impaired functioning.

A survey of knowledge and attitudes about HIV and AIDS among medical students.

Researchers have found that a significant number of medical students harbor attitudes that have a negative impact on their willingness to care for persons who are HIV positive or have AIDS. To assess current HIV and AIDS knowledge and attitudes, the authors administered a 25-item survey tailored for medical professionals to 63 preclinical medical students. Respondents' mean score on the knowledge scale was 6.25 (SD 1.63) out of a possible score of 10. Factor analysis suggested three major groupings of medical students with regard to attitudes. The largest group had generally positive attitudes about patients with HIV and AIDS; two subgroups, however, would tend to refer such patients to another physician. One subgroup reported feeling more uncomfortable with homosexual behavior and with HIV-seropositive patients than they did with patients with other infectious diseases. This group also expressed discomfort with physically touching HIV-seropositive clients. The other group expressed discomfort with taking a patient's sexual history. Effective educational interventions must take these findings into account.
