Abstract
INTRODUCTION This study explored the behaviours of people living with HIV in Singapore and Hong Kong in terms of achieving and maintaining their physical and psychological wellbeing in relation to HIV, to identify the challenges and support needed in HIV care. METHODS This qualitative study involved 90-minute interviews among Singapore and Hong Kong people living with HIV aged ≥18 years to explore health-related quality of life perceptions and gaps in patient empowerment in HIV care during February-May 2022. The COM-B (C: Capability; O: Opportunity; M: Motivation; B: Behaviour) framework was used during data analysis to identify behaviour facilitators and barriers for people living with HIV to achieve and maintain their wellbeing. Detailed accounts of respondents' experience of living with and managing HIV, that is what worked well, unmet needs and perceived significance of wellbeing indicators, were analysed qualitatively via a combination of inductive content and deductive frameworks. RESULTS A total of 30 and 28 respondents were recruited from Singapore (SG) and Hong Kong (HK), respectively. Most respondents were aged 20-49 years (SG: 83.3%; HK: 64.3%), males (SG: 96.7%; HK: 92.9%), men who have sex with men (SG: 93.3%; HK: 71.4%), had university or higher education (SG: 73.3%; HK: 50.0%) and were fully employed (SG: 73.3%; HK: 57.1%). In both Singapore and Hong Kong, physical health was considered a key focus of overall wellbeing, albeit attention to long-term health associated with cardiovascular and renal health was less salient. The impact of symptoms, side effects of treatment, mood and sleep were among the top wellbeing indicators of importance. Respondents felt that insufficient information was provided by physicians, citing consultation time and resource constraints impeding further expression of concerns to their physicians during consultation. Respondents prioritized functional wellness and delegated psychosocial health to supportive care professionals, patient groups, families and/or friends. CONCLUSIONS There is a need in Singapore and Hong Kong to empower people living with HIV to establish better communications with their physicians and be more involved in their treatment journey and equally prioritize their psychosocial wellbeing.

Abstract
Interrelationships among HIV-associated neurocognitive dysfunction, avoidant coping, cognitively-oriented coping, and psychological distress were examined using structural equation modeling in an ethnically diverse sample of 209 adults predominantly in the mid-range of illness. Global neurocognitive deficits, assessed with the HIV-dementia scale, were associated with higher levels of avoidant coping, lower levels of cognitive coping, and a higher avoidant/cognitive coping ratio, which were each in turn associated with higher psychological distress measured by a latent factor comprising symptoms of depression, anxiety, and HIV-related distressing thoughts. There were significant indirect effects through avoidant coping and a higher avoidant/cognitive coping ratio. Results suggest the presence of HIV-associated neurocognitive deficits may interfere with the utilization of cognitive-based coping strategies and increase reliance on more maladaptive strategies, which in turn may translate to elevated reports of psychological distress. Findings may help inform interventions aimed at reducing avoidant coping and psychological distress, two factors associated with accelerated HIV disease progression.

Abstract
People aging with HIV face social stressors which may negatively affect their overall nutrition. Here, we assess relationships between self-reported measures of depression, perceived stress, social support, and food insecurity with diet quality in older adults with HIV. A retrospective analysis of self-reported data from parent study at The University of Alabama at Birmingham 1917 HIV Clinic was performed. The study sample consisted of sixty people living with HIV (PLWH) with controlled HIV infection (<50 copies/mL), aged 50 years or older who participated in a cross-sectional microbiome study. Dietary intake was measured using the NHANES 12-month Food Frequency Questionnaire (FFQ) and three Automated Self-Administered (ASA) 24-hr diet recalls to calculate diet quality scores using the Mediterranean Diet Score (MDS); alternative Healthy Eating Index (aHEI); and the Recommended Food Score (RFS) indices. Food insecurity was measured with the Food Security Questionnaire (FSQ). Participants completed the following psychosocial scales: (1) depression - Patient Health Questionnaire-8 (PHQ8); (2) perceived stress - Perceived Stress Scale (PSS-10); (3) social support - Multidimensional Scale of Perceived Social Support (MSPSS). Linear regression models were used to investigate relationships among variables controlling for gender and income. The cohort was characterized as follows: Mean age 56 ± 4.6 years, 80% African-American, and 32% women. Mean body mass index (BMI) was 28.4 ± 7.2 with 55% reporting food insecurity. Most participants reported having post-secondary education (53%), although 77% reported annual incomes <$20,000. Food insecurity was independently associated with measures of poor dietary intake: aHEI (β = -0.08, p = .02) and MDS (β = -0.23, p < 0.01) and with low dietary intake of fibre (β = -0.27, p = .04), vitamin E (β = -0.35, p = .01), folate (β = -0.31, p = .02), magnesium (β = -0.34, p = .01) and copper (β = -0.36, p = .01). These data indicate food insecurity is associated with poor diet quality among PLWH. Clinical interventions are needed to improve food access for PLWH of low SES.

Abstract
Optimal adherence to antiretroviral therapy (ART) is associated with favorable HIV outcomes, including higher CD4 cell counts, HIV virus suppression and a lower risk of HIV transmission. However, only 25% of people living with HIV/AIDS (PLWH) in the USA are virally suppressed. Sub-optimal adherence (<90-95%) contributes to antiretroviral resistance and worse medical outcomes, including more rapid progression to AIDS and death. Psychosocial factors and religion/spirituality (R/S) have a significant impact on ART adherence, but the findings are mixed. The purpose of this study was to examine religious and psychosocial correlates and predictors of ≥90% ART adherence in PLWH. A cross-sectional study was conducted with a sample of 292 outpatient PLWH in the Southeastern USA. Participants completed computerized surveys. The mean ART adherence percentage was 80.9% and only about half reported ≥90% adherence. There were statistically significant differences in ART adherence rates based on age, depressive symptom status and frequency of religious attendance and prayer. Praying at least once a day was significantly associated with ≥90% ART adherence (OR = 2.26, 95% CI [1.06-4.79], p < 0.05). Social support satisfaction was also significantly associated with ART adherence (OR = 1.52, 95% CI [1.11-2.08], p < 0.05) and energy/fatigue/vitality (OR = 1.03, 95% CI [1.00-1.05], p < 0.05).

Abstract
OBJECTIVES To quantify the association between intimate partner violence (IPV) and incident HIV infection in women in the Rakai Community Cohort Study between 2000 and 2009. DESIGN AND METHODS Data were from the Rakai Community Cohort Study annual surveys between 2000 and 2009. Longitudinal data analysis was used to estimate the adjusted incidence rate ratio (IRR) of incident HIV associated with IPV in sexually active women aged 15-49 years, using a multivariable Poisson regression model with random effects. The population attributable fraction was calculated. Putative mediators were assessed using Baron and Kenny's criteria and the Sobel-Goodman test. RESULTS Women who had ever experienced IPV had an adjusted IRR of incident HIV infection of 1.55 (95% CI 1.25-1.94, P = 0.000), compared with women who had never experienced IPV. Risk of HIV infection tended to be greater for longer duration of IPV exposure and for women exposed to more severe and more frequent IPV. The adjusted population attributable fraction of incident HIV attributable to IPV was 22.2% (95% CI 12.5-30.4). There was no evidence that either condom use or number of sex partners in the past year mediated the relationship between IPV and HIV. CONCLUSION IPV is associated with incident HIV infection in a population-based cohort in Uganda, although the adjusted population attributable fraction is modest. The prevention of IPV should be a public health priority, and could contribute to HIV prevention.

Abstract
OBJECTIVE To evaluate the immediate and long-term effectiveness of mindfulness-based stress reduction (MBSR) on biological and symptomatological markers of health among human immunodeficiency virus-positive (HIV+) patients in Tehran, Iran. METHODS Using a randomized controlled trial design, data from 173 HIV+ patients (CD4 count > 250) not yet receiving antiretroviral therapy, who participated in either an 8-week MBSR (n = 87) or a brief education and support condition (n = 86) at the Imam Khomeini Hospital, were analyzed. Assessments included CD4 count, Symptom Checklist-90-Revised (SCL-90R), and Medical Symptom Checklist (MSCL) at baseline, immediate post-treatment, and at the 3-, 6-, 9-, and 12-month follow-up periods. RESULTS The treatment-adherent sample had a mean (standard deviation) age of 35.1 (6.5) years and 69% were male. Linear mixed-model estimates indicated that, in the MBSR condition, the mean CD4 count increased from baseline up to 9 months after treatment and then returned to baseline level at 12 months. Improvements in mean SCL-90R (up to 6 months) and MSCL (up to 12 months) scores were observed for the MBSR condition, whereas education and support condition scores remained the same over time; however, only MSCL improvements significantly differed between groups and these changes lasted up to the final assessment. CONCLUSIONS Findings suggest that among treatment-adherent Iranian HIV+ patients not yet receiving antiretroviral drug treatment, MBSR seems to have the strongest potential to improve self-reported medical symptoms.

Abstract
OBJECTIVES The objective of this study was to identify and describe ways that a spiritually based intervention of silently repeating a mantram-sacred word or phrase-was used as a coping strategy for managing human immunodeficiency virus (HIV) disease. DESIGN The design was a qualitative research method, the critical incident technique. SETTINGS/LOCATION The study was conducted at an academically affiliated Veterans Affairs Hospital in southern California. SUBJECTS The subjects were outpatient adults living with HIV (n=32) who were receiving care through HIV clinics, community agencies, and HIV providers. INTERVENTIONS Subjects who participated in the intervention arm of a randomized controlled trial that tested the efficacy of a 5-weekly group mantram intervention were interviewed 2 months postintervention. Follow-up telephone interviews were specifically aimed at identifying instances of mantram use, and also participant perceptions of intervention usefulness or nonusefulness. OUTCOME MEASURES The outcome measures comprised categorization and comparison of the types and frequency of incidents reported, describing ways that the intervention was "helpful" or "not helpful" in managing stressors of HIV disease. RESULTS Participants reported a total of 185 incidents. Analysis and classification of the incidents resulted in eight mutually exclusive categories, including Increasing calm and/or peace, Mastering the technique, Changing my viewpoint, Increasing personal awareness, Adjusting behaviors, Managing physical symptoms, Increasing spirituality, and Enhancing relationships. CONCLUSIONS This study shows support for the benefits of the mantram intervention for adults with HIV. Additionally, the spiritually based mantram repetition intervention was found to be more helpful in providing a convenient, portable tool for managing a wide range of situations related to living with HIV disease.

Abstract
Acute and chronic life stressors have a detrimental effect on the health of people living with HIV. Psychosocial resources such as mastery, coping, and social support may play a critical role in moderating the negative effects of stressors on health-related quality of life. A total of 758 participants provided baseline enrolment data on demographics (age, gender, ethnicity, sexual orientation, education, employment, income), clinical variables (CD4 counts, viral load, AIDS-defining condition, time since HIV diagnosis), psychosocial resources (mastery, coping, social support), life stressors (National Population Health Survey [NPHS] Stress Questionnaire), and health-related quality of life (SF-36). We performed hierarchical multivariate regression analyses to evaluate the potential moderating effects of psychosocial resources on the relationship between stressors and health-related quality of life. The top three stressors reported by participants were trying to take on too many things at once (51%), not having enough money to buy the things they needed (51%), and having something happen during childhood that scared them so much that they thought about it years later (42%). Life stressors were significantly and inversely associated with both physical and mental health-related quality of life. Mastery and maladaptive coping had significant moderating effects on mental health but not on physical health. These results suggest that developing interventions that improve mastery and reduce maladaptive coping may minimize the negative impact of life stressors on the mental health of people with HIV. They also highlight that it is important for clinicians to be mindful of the impact of life stressors on the health of patients living with HIV.

Abstract
Cross-sectional data were collected on a sample of 259 gay and bisexual, male-identified individuals as part of a larger study of the psychosocial functioning of lesbian, gay, bisexual, and transgender persons. Analyses considered differences between HIV-positive and HIV-negative men in relation to active and religious coping strategies; avoidant coping strategies (specifically, illicit drug use); and the psychosocial states of anxiety, hostility, and depression in relation to self-reported HIV-status of the participants. As compared with HIV-negative men, the HIV positive participants indicated a greater likelihood of engaging in illicit substance use within the previous 3 months, as well as higher levels of both active and religious coping strategies. Illicit substance use also was found to be related to higher levels of depression, anxiety, and hostility. A multivariate model indicated a significant difference in substance-based and active coping strategies among the men surveyed, with persons with a self-reported HIV-positive serostatus endorsing higher levels of both strategies. These results and their implications for prevention and future research are discussed, rooted in the understanding that a complex reality for coping is often enacted by HIV-positive men.

Abstract
There is a growing epidemiological literature focusing on the association between psychosocial stress and human immunodeficiency virus (HIV) disease progression or acquired immunodeficiency syndrome (AIDS), but inconsistent findings have been published. We aimed to quantify the association between adverse psychosocial factors and HIV disease progression. We searched Medline; PsycINFO; Web of Science; PubMed up to 19 January 2009, and included population studies with a prospective design that investigated associations between adverse psychosocial factors and HIV disease progression or AIDS. Two reviewers independently extracted data on study characteristics, quality, and estimates of associations. The overall meta-analysis examined 36 articles including 100 psychosocial and disease related relationships. It exhibited a small, but robust positive association between adverse psychosocial factors and HIV progression (correlation coefficient as combined size effect 0.059, 95% confidence interval 0.043-0.074, p<0.001). Notably, sensitivity analyses showed that personality types or coping styles and psychological distress were more strongly associated with greater HIV disease progression than stress stimuli per se, and that all of the immunological and clinical outcome indicators (acquired immunodeficiency syndrome stage, CD4+ T-cell decline, acquired immunodeficiency syndrome diagnosis, acquired immunodeficiency syndrome mortality, and human immunodeficiency virus disease or acquired immunodeficiency syndrome symptoms) except for viral load exhibited detrimental effects by adverse psychosocial factors. In conclusion, the current review reveals a robust relationship between adverse psychosocial factors and HIV disease progression. Furthermore, there would appear to be some evidence for particular psychosocial factors to be most strongly associated with HIV disease progression.

Abstract
Substance use is prevalent among HIV-positive adults and linked to a number of adverse health consequences; however little is known about risk and protective factors that influence substance use among HIV-positive adults coping with AIDS-related bereavement. Using structural equation modeling (SEM), male gender, diagnostic indications of antisocial and borderline personality disorders (PD), and grief severity were tested as risk factors, and social support as a protective factor, for alcohol and cocaine use among a diverse sample of 268 HIV-positive adults enrolled in an intervention for AIDS-related bereavement. Results indicated that the hypothesized model fit the study data. Male gender, PD indication, and social support had direct effects on substance use. PD had significant indirect effects on both alcohol and cocaine use, mediated by social support, but not by grief. Finally, both PD and social support had significant, but opposite, effects on grief. Implications for intervention and prevention efforts are discussed.

Abstract
OBJECTIVES Previous research among HIV-infected individuals suggests that spiritual well-being is inversely related to psychological distress and rates of disease progression. Use of a mantram, a spiritual word or phrase repeated frequently and silently throughout the day, has been associated with decreased psychological distress and increased spiritual well-being. This study compared the effects of 2 interventions-a spiritually-based mantram intervention versus an attention-matched control group-on faith/assurance and average salivary cortisol levels among HIV-infected individuals. METHODS Using a randomized design, HIV-infected adults were assigned to the intervention (n = 36) or control condition (n = 35). Faith scores and saliva (collected at 7 a.m., 11 a.m., 4 p.m., and 9 p.m.) were assessed at preintervention, postintervention, and 5-week follow-up. Path analyses tested competing models that specify both concurrent and sequential relationships between faith and average daily cortisol levels while comparing groups. RESULTS Faith levels increased among mantram participants from pre- to postintervention. Greater faith at preintervention was significantly associated with lower average cortisol at postintervention in the mantram group but not in the controls. The associations between faith at postintervention and cortisol levels at 5-week follow-up were significant among both groups but weaker than the pre- to postintervention association identified in the mantram group. CONCLUSIONS These results suggest the presence of lagged or antecedent consequent relationships between faith and cortisol, which may be enhanced by mantram use. Decreased cortisol could potentially benefit immune functioning among HIV-infected individuals.

Type C coping, alexithymia, and heart rate reactivity are associated independently and differentially with specific immune mechanisms linked to HIV progression. Brain Behav Immun 2008; 22:781-92. [PMID: 18346864 DOI: 10.1016/j.bbi.2008.02.003] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2007] [Revised: 02/05/2008] [Accepted: 02/05/2008] [Indexed: 01/04/2023] Open
Abstract
The maladaptive Type C coping style has been linked to disease progression in HIV and other immunologically mediated disorders. We hypothesized that strong Type C coping, higher levels of alexithymia, and greater cardiovascular (particularly heart rate) responses to, and prolonged recovery from stress would be associated with poorer functioning of immune parameters previously linked to HIV pathogenesis and progression: (1) antigen-stimulated production of the beta (beta)-chemokines MIP-1 alpha and MIP-1 beta, which bind to the HIV co-receptor CCR5 and block HIV entry into CD4(+) lymphocytes; and (2) antigen-stimulated production of the proinflammatory cytokine interleukin-6 (IL-6), which synergizes immune activation associated with HIV replication. We examined relations among psychological, cardiovascular, and immune variables in a baseline sample of 200 HIV-infected, predominantly African American outpatients attending an HIV primary care clinic in inner-city Baltimore. In regression analyses adjusted for CD4(+) count and age, strong Type C coping was associated with significantly higher IL-6 production, as predicted. The theoretically related construct of alexithymia was correlated with significantly lower stimulated production of HIV-inhibiting MIP-1 alpha. Independent of alexithymia, greater heart rate reactivity, and poorer heart rate recovery in response to experimental stressors were also significantly associated with lower production of MIP-1 alpha, adjusted for cardiovascular medications, methadone use, CD4(+) count, and age. These findings support our primary set of hypotheses that maladaptive Type C coping, alexithymia, and heart rate reactivity/recovery are associated with disturbances in two key immune parameters implicated in HIV pathogenesis. Our secondary hypothesis, that dysregulated heart rate reactivity may mediate the connections between Type C coping and/or alexithymia and IL-6/ MIP-1 alpha was not confirmed. The finding that Type C coping, alexithymia, and heart rate reactivity/recovery are associated independently and differentially with specific aspects of relevant immune functioning may reflect distinct biobehavioral pathways that contribute to HIV progression.

Abstract
The purpose of this study was to determine the correlation of perceived stress with selected physiological and psychological factors in an HIV-infected, predominantly African American population and to assess the multivariable effects on perceived stress. The variables that correlated significantly with perceived stress were entered into a backward stepwise regression model. Pearson's r analysis showed significant correlations between perceived stress and state and trait anxiety, depression, HIV-related symptoms, sleep quality, daytime sleepiness and fatigue. State and trait anxiety, depression and fatigue retained significance (p<0.1) in the final regression model. These factors explained approximately 80% of the variance in perceived stress. The significant interactions of multiple physiological and psychological correlates suggest that perceived stress is a complex outcome with a multifactorial etiology. Further, the model suggests that psychological factors may contribute to perceived stress in this population more than physiological factors such as HIV-related symptomatology or stage of disease.

Abstract
OBJECTIVE Most previous longitudinal studies demonstrating relationships between psychosocial variables and human immunodeficiency virus (HIV) disease progression utilized samples of gay men accrued before the era of highly active antiretroviral treatment (HAART), without including viral load (VL) as an indicator of disease progression or assessing the impact of medication adherence. This study sought to determine whether psychosocial variables would predict both CD4 and VL changes in a diverse sample assessed entirely during the era of HAART and accounting for adherence effects. METHODS This longitudinal study assessed a multiethnic HIV+ sample (n = 177) of men and women in the midrange of illness (CD4 number between 150 and 500; no previous acquired immunodeficiency syndrome [AIDS]-defining symptom) every 6 months for 2 years. Hierarchical linear modeling was used to model change in CD4 and VL controlling for sociodemographics (age, gender, ethnicity, education) and medical variables (baseline CD4/VL, antiretroviral medications at each time point, adherence). RESULTS Baseline depression, hopelessness, and education predicted the slope of CD4 and VL. Avoidant coping and life event stress predicted VL change. Cumulative variables produced stronger relationships (depression, avoidant coping, and hopelessness with CD4/VL slope and life events stress with VL slope). High cumulative depression and avoidant coping were associated with approximately twice the rate of decline in CD4 as low scorers and greater relative increases in VL. Social support was not significantly related to CD4 or VL slope. CONCLUSIONS Psychosocial factors contribute significantly to the variance in HIV disease progression (assessed through CD4 number and VL) in a diverse sample, accounting for adherence and do so in the era of HAART.

Abstract
Substantial recent research has focused on examining hormone indicators of psychosocial stress and on how relationships between stress and hormone changes might be linked to chronic illness. Particular attention has been paid to disease progression in cancer and HIV/AIDS. This focus has generated a plethora of research which has contributed both theoretically and clinically to the understanding of disease experience and the rate of disease progression. Measurement of salivary cortisol levels and diurnal variation has substantially advanced research methodology. Applying the unifying concept of allostasis and accumulated lifetime stress, this review attempts to assess the relevance of psychological and stress hormone correlates to disease resistance and health, through an examination of such correlates on the experience and outcomes of stress during childhood. Focus is on the role and importance of naturalistic social stress experiences such as school transition in healthy children, with emphasis on salivary cortisol as an endocrine marker of HPA-axis activation. It is argued that differing research perspectives offer valuable insight into the often assumed but largely unexplored links between early life experience and subsequent physical health outcomes in adulthood. Longitudinal studies incorporating measures of acute physical health outcome and of learning and memory are clearly needed.

Abstract
The issue of whether optimism may prospectively protect against disease progression is one that has generated much interest, with mixed results in the literature. The purpose of this study was to determine whether dispositional optimism predicts slower disease progression in HIV. Two indicators of disease progression, CD4 counts and viral load, were assessed over 2 years in a diverse group (men, women, White, African American, Hispanic) of 177 people with HIV in the midrange of disease at entry to the study. Optimism predicted slower disease progression (less decrease in CD4 and less increase in viral load) controlling for baseline CD4 and viral load, antiretroviral treatment, gender, race, education, and drug use. Those low on optimism (25th percentile) lost CD4 cells at a rate 1.55 times faster than those high on optimism (75th percentile). Optimists had higher proactive behavior, less avoidant coping, and less depression: These variables mediated the linear optimism-disease progression relationship. Thus, optimists may reap health benefits partly through behavioral (proactive behavior), cognitive (avoidant coping), and affective (depression) pathways. Implications, limitations, and interpretations are discussed.

Abstract
Although the phenomenon that psychological stress influences disease onset and progression is well established, the mechanisms underlying stress-evoked compromise of immune function remain unspecified. To test the hypothesis that energetic shortages compromise immunity, we evaluated the effectiveness of pyruvate, a metabolic supplement, to prevent stress-evoked suppression of mitogen-stimulated splenocyte proliferation. Male C57BL/6 mice were subjected to 2h of restraint once daily for 14 days. Consistent with previous studies, mitogen-stimulated splenocyte proliferation was reduced after restraint; in contrast, mice that received pyruvate injections immediately following each episode of restraint did not reduce splenocyte proliferation. In addition, restraint-evoked corticosterone elevation did not habituate in animals treated with pyruvate, suggesting that glucocorticoids are not exclusively immunosuppressive. The ratio of pyruvate to lactate, an index of aerobic metabolism, was elevated in mice exposed to restraint suggesting that mice exposed to restraint were preferentially using aerobic metabolism and producing more ATP per unit of pyruvate than non-restrained mice. Furthermore, two of the effective doses of pyruvate (0.5 and 500.0mg/kg) altered glucose levels suggesting a metabolic function of the supplement. Although several different mechanisms could possibly mediate the changes in splenocyte proliferation, these results support the hypothesis that stress-evoked immunosuppression may be a function of metabolic energy shortages and can be prevented via pyruvate supplementation.

Abstract
The relationships between HIV-related pain, psychiatric disorders, and suicidal ideation (SI) are not well understood. The presented research investigated the ability of pain, psychiatric diagnoses, coping styles, and locus of control (LOC) to predict SI in 75 HIV-positive persons, using a sequential logistic regression. Reported psychiatric diagnoses included depression, anxiety, and substance abuse disorders. Variance accounted for by these analyses was approximated at 33%, with pain severity independently predicting SI after accounting for psychiatric diagnoses. Coping and LOC did not add significantly to the models. Given the prevalence of pain in this population, these results underscore the importance of assessing and treating pain and SI in persons with HIV.

Abstract
BACKGROUND Behçet's disease is a systemic immunoinflammatory disease of young adults characterized by systemic vasculitis of arteries and veins. Although many studies have been published since its discovery in 1937, the etiopathogenesis of this unique disorder is still unclear. OBJECTIVE To assess the relationship between stress factors, psychological and somatic symptoms, and coping mechanisms in patients with Behcet's disease. METHOD Thirty-four patients with Behcet's disease and 43 control subjects were compared by using sociodemographic data collection forms, a psychosocial and environmental problems list, the Beck Anxiety Inventory (BAI), Hamilton Depression Rating Scale (HAM-D) and Toronto Alexithymia Scale (TAS). RESULTS Twenty-four patients (70.6%) defined stress factors in the first stage of the disease. Twenty-seven (79.4%) out of 34 patients stated that the recurrence period of the disease was related to the stress factors. Fear was expressed by 10 (29.4%) patients, sadness by 11 (32.3%), and fear plus sadness by 13 (38.2%) when they first learnt the diagnosis. While coping with these emotions 14 (41.2%) revealed active-reliance strategy. A statistically significant difference was present between the Behcet's patients and control subjects regarding TAS (P < 0.05), HAM-D (P < 0.001) and BAI (P < 0.001) scores. CONCLUSION It seems that stressful life events have important implications in both relapsing and remission periods of Behçet's disease via secondary problems.

Abstract
Male mice are more susceptible than female mice to the murine retrovirus FIS-2. We previously reported that sex-related factors influence early virus replication via mechanisms involving a glucocorticoid response element (GRE) in the long terminal repeat (LTR) enhancer region. In the present study, we investigated further the influence of sex and steroid hormones on early murine retrovirus dissemination and immune functions. In male mice we found a correlation between an early expansion of the CD8+ cell subset and rapid infection of lymphocytes, including CD8+ cells. Virus load in blood declined faster in females than in males, and the postpeak declines coincided with more rapidly generation of antibodies against virus-positive cells. Moreover, female-derived T-cells responded better to in vitro mitogen stimuli than male-derived T-cells. Physiological concentrations of progesterone and dexamethasone induced a dose-dependent inhibition of T-cell proliferation. Administration of progestin in vivo did not modify early FIS-2 production in female mice. Male castrated mice, who were notably less involved in aggressive behaviour and fighting compared to male control mice, had a significant delay of virus dissemination. We suggest that testosterone-dependent aggression, with successive enhanced stress hormone levels, may influence both FIS-2 replication and immune responses during infection.

Abstract
OBJECTIVE Women are particularly prone to stress with respect to living with HIV. Stress management behaviors can mediate the stress response and improve health outcomes in HIV-positive individuals. The purpose of this descriptive cross-sectional study was to examine stress and Transtheoretical Model (TTM) indicators of stress management behaviors in HIV-positive women. METHODS 126 HIV-positive women recruited from diverse HIV-care clinics in northeast Ohio completed standardized self-report research instruments to measure stress, stress management behaviors, stage of change, self-efficacy, and decisional balance (pros and cons). RESULTS Women reported higher levels of stress in the later phase of HIV infection (P<.05). Highly stressed women in this study reported infrequently using stress management behaviors and a low level of perceived efficacy to manage stress although they perceived the pros of managing stress to be high (P<.01). Stress management behaviors were significantly related to stage of change (P<.01), self-efficacy (P<.01), and the cons of managing stress (P<.05). Graphed patterns of decisional balance examined by stage of change and stress management behavior were atypical in this sample. CONCLUSIONS Clinicians and researchers can use the TTM to describe behavioral indicators of stress management in HIV+ women. However, further research is needed to more fully understand behavioral processes HIV+ women can use to adopt and maintain stress management behaviors.

Abstract
OBJECTIVE This study examines whether there may be an immune component that protects a relatively rare group of HIV-infected people with very low CD4 cell counts (< or = 50 x 10(6)/l) who have prolonged asymptomatic periods. DESIGN/METHODS Three groups were recruited in Miami: (i) healthy low CD4 cell count patients (HLC; n = 30) who, for 9 months had < 50 x 10(6) CD4 cells/l, were asymptomatic and were not on protease inhibitors during that time; (ii) HIV comparison group (Comp; n = 60) who had CD4 cell counts predominantly 150 x 10(6) to 400 x 10(6)/l and never had AIDS Category C symptoms; this group was also followed for CD4 cell count and viral load change over 6 months; and (iii) healthy community controls (n = 33). The study was replicated at the University of California at Los Angeles (UCLA) with HLC (n = 31) versus HIV-negative laboratory controls (n = 28). RESULTS The HLC patients were significantly higher than the Comp group on natural killer cell cytotoxicity (NKCC) and natural killer cell number (NK#) despite their lower CD4 cell numbers and higher viral loads. In fact, there was no difference between the HLC group and the healthy community control group in NK# or NKCC. The NK findings were replicated at UCLA. A retrospective analysis showing that higher NKCC was related to fewer prior symptoms in the HLC group, and prospective analysis in the Comp group showing that NK# predicted a lower increase in viral load over 6 months further supported the importance of NK# and NKCC. CONCLUSIONS Non-specific cellular immunity may be a factor protecting the health of HIV sero-positive individuals with very low CD4 cell counts.
