The impact of experiencing lipodystrophy on the sexual behaviour and well-being among HIV-infected homosexual men

Effect of the duration of protease inhibitor therapy in HIV-infected individuals on the severity of obstructive sleep apnea

Background

Protease inhibitors (PIs) are a vital part of the antiretroviral therapy. Long-term use of PIs may cause lipodystrophy, a clinical syndrome characterized by peripheral lipoatrophy and central fat accumulation, which may increase the risk of developing obstructive sleep apnea (OSA) in HIV-infected patients. We hypothesize that a longer duration of PIs' use might be associated with increasing severity of OSA in HIV-infected patients.

Materials and Methods

This was a retrospective cohort study of HIV-infected patients who were treated with PIs, who presented with symptoms suggestive of OSA, and underwent nocturnal polysomnography. The primary objective of the study is to evaluate the association between the duration of PIs' use and the severity of OSA. The duration of PIs' use measured in months was recorded for each patient. The primary outcome of interest was the apnea-hypopnea index (AHI) obtained at the time of the sleep study. Data were analyzed using univariate and multivariate linear regression between AHIs with PIs' use as well as other predictors.

Results

A total of 54 patients diagnosed with HIV and OSA were included in the study cohort for the analysis. Sleep study body mass index (BMI; P = 0.042) and change in BMI (ΔBMI; P = 0.027) were the only statistically significant independent predictors of AHI. The association between AHI and PIs' use duration was found to be nonlinear and nonsignificant. Gender differences evaluation suggested possible duration-related effect relationship between PIs and OSA severity among HIV-infected men exposed to PIs within a 66-month duration.

Conclusion

We did not observe a significant association between PIs' use duration and the severity of OSA.

Adherence with metreleptin therapy and health self-perception in patients with lipodystrophic syndromes

Background

Although metreleptin replacement therapy was shown to improve metabolic alterations in lipodystrophic syndromes, patients’ adherence and satisfaction with treatment have never been evaluated. The 20 patients with lipodystrophic syndromes participating in the French compassionate program of metreleptin therapy filled in a self-questionnaire including an Adherence Evaluation Test, the Treatment Satisfaction Questionnaire for Medication (TSQM®-vII), and items about physical appearance.

Results

15 patients were women, median age was 32.5 years (IQT 25–75 (16.2;49.5), 18 had diabetes. Adherence with metreleptin (one daily subcutaneous injection) was poor in 25%, excellent in 25% and acceptable in 50% of patients. On a 0-to-100 scale, patients’ satisfaction scores reached 66.7 (52.1;81.2) for effectiveness, 55.6 (44.4;66.7) for ease/comfort of use, and 83.3 (52.1;83.3) for global satisfaction with metreleptin therapy. Self-reported side effects were frequent injection site reactions 100 (79.2;100). Satisfaction scores did not differ in patients with partial (n = 10) or generalized (n = 10) lipodystrophic syndromes, did not correlate with metabolic improvement, but were significantly higher in compliant patients with fewer side effects. Morphological appearance was reported improved under metreleptin therapy in 13 among 17 patients.

Conclusions

Metreleptin increases health self-perception and decreases morphotype-associated stigmatization in most patients with lipodystrophic syndromes, but poor comfort of use and local side effects weaken adherence.

Ten-Year Safety with Polyacrylamide Gel Used to Correct Facial Lipoatrophy in HIV-Infected Patients

Long-term results (>5 years) for synthetic substances used to repair facial lipoatrophy have not been published. We performed a cross-sectional study to evaluate the 10-year safety of polyacrylamide hydrogel (Aquamid) among the 751 patients from our unit who received facial infiltrations at least 10 years ago. Epidemiological and clinical data such as complications and patient satisfaction were collected. We also identified those patients who presented a facial infection at any time after infiltration. A total of 104 patients had received Aquamid at least 10 years ago. Before infiltrations, 24.0%, 41.3%, and 34.7% presented very severe, severe, and moderate facial lipoatrophy, respectively. After a mean (SD) of 10.3 (0.5) years since the infiltrations, 19.2%, 47.7%, and 31.7% of patients reported moderate, mild, and no signs of facial lipoatrophy. The values reported by physicians for the same categories were 1.9%, 10.6%, and 87.5%. Indurations were detected in 6.7% of patients and nodules in 3.8%. Five patients (4.8%) had a local infection. A further 15 patients with a shorter follow-up (less than 10 years) presented local infections (overall incidence considering the 751 patients who received infiltrations of Aquamid, 2.7%); the product had to be withdrawn in three cases. The majority of patients were highly satisfied (74.8%) or satisfied (23.4%) with the cosmetic results; among patients with severe or very severe lipoatrophy at baseline, 31.4% were satisfied and 65.7% were highly satisfied. Infiltrations with polyacrylamide hydrogel (Aquamid) are a safe strategy for the treatment of facial lipoatrophy in the long term. The rate of severe complications was low, and patient satisfaction with the cosmetic results was high. However, facial infections may appear in the long term. Therefore, HIV-infected patients who received synthetic substances should be carefully monitored over time.

HIV and metabolic, body, and bone disorders: what we know from low- and middle-income countries

Globally, the HIV epidemic is evolving. Life expectancy for HIV-infected individuals has been extended because of more effective and more widely available antiretroviral therapy. As a result, chronic noncommunicable diseases (NCDs) have become important comorbid conditions. In particular, HIV-infected persons are increasingly at risk of developing metabolic (diabetes, dyslipidemias), body composition (lipodystrophy, overweight/obesity) and bone mineral density abnormalities. We have summarized the published epidemiological and clinical literature regarding these HIV-NCD comorbidities in low- and middle-income countries (LMICs). We found important gaps in knowledge. Specifically, there are few studies that use standardized methods and metrics; consequently, prevalence or incidence data are not comparable. There are very little or no data regarding the effectiveness or cost-effectiveness of clinical monitoring or therapeutic interventions for metabolic disorders in HIV-infected individuals. Also, although NCDs continue to grow in the HIV-negative population of most LMICs, there are few data comparing the incidence of NCD comorbidities between HIV-infected and HIV-negative populations. To address these gaps, we describe potential research and capacity development priorities for the future.

Lipodystrophy Is Common Among Ethiopian Patients on Highly Active Antiretroviral Therapy but Is Not Associated With Quality of Life or Medication Adherence

Clinical experience suggests that lipodystrophy (LD) can have a profound impact on quality of life (QOL) and medication adherence (MA). Thus, a hospital-based, cross-sectional study was conducted to determine the prevalence of LD and its association with QOL and MA. A total of 405 participants were included in the study. The majority of participants were female (64.5%), with a mean age of 35.69 years (SD = 9.63 years). The prevalence of LD was 30.9%. Multiple logistic regression analysis showed that type of regimen initially used is an independent predictor of severity of LD (adjusted odds ratio, 44.16; 95% confidence interval, 10.56-184.59; P = .001). Quality of life was assessed with the World Health Organization Quality of Life short form instrument (WHOQOL-BREF), and medication adherence was assessed by self-report. The mean WHOQOL-BREF score of the participants was 53.48; the highest mean value was in the domain of physical health (68.56) and the lowest was in the social relationships domain (47.09). The majority of the patients scored lower (ie, in the lowest 5 deciles) in the domains of psychological health, social relationships, and environment compared with physical health. No differences in the WHOQOL-BREF measurements were observed, except in the environment domain, between patients with moderate LD and severe LD ( P = .02). The LD severity was not associated with self-reported MA ( P = .42). With the exception of the psychological health domain ( P = .044), participants' WHOQOL-BREF scores were not significantly associated with MA. Lipodystrophy was not associated with QOL or MA. The prevalence of LD in the present study was within the range of previous reports; however, the mean WHOQOL-BREF score of Ethiopian patients in this study is lower compared with reports from developed countries.

Trends in unsafe sex and influence of viral load among patients followed since primary HIV infection, 2000-2009

BACKGROUND

In the current context of increasing unsafe sex, HIV incidence may have evolved, depending on HIV prevalence in sexual networks and, among HIV-infected persons who practice unsafe sex, on their infectivity and partners' HIV serostatus. We examined calendar trends in sexual behaviours at risk of HIV-1 transmission (SBR) among 967 adults followed since primary HIV infection (ANRS PRIMO cohort) and relationship with current treatments and viral load.

METHODS

Patients completed since 2000 self-administered questionnaires on sexual practices every 6 months. SBR with HIV-negative/unknown partners were analyzed among 155 heterosexual women, 142 heterosexual men and 670 MSM by using logistic generalized estimating equation models (6656 visits).

RESULTS

During 2000-2009, the frequency of SBR did not increase significantly among women with steady partners; risk factors were a low education level and alcohol/smoking use. Among heterosexual men with steady partners, the frequency of SBR doubled since 2006; during this period, the only associated factor was combined antiretroviral treatment for at least 6 months or viral load less than 400 copies/ml. Among MSM, SBR increased gradually over time; SBR with steady partners was associated with a low education level and alcohol use. SBR was more frequent among MSM with casual partners; no association with viral load was found.

CONCLUSION

In France, recent trends and risk factors in unprotected sex with HIV-negative/unknown partners differ according to sex/sexual preference. The recent increase in SBR among heterosexual men with low viral load may be related to increasing awareness of the 'treatment-as-prevention' concept. The lack of association between SBR and viral load among MSM supports use of treatment-as-prevention as part of diversified prevention strategies.

Rosiglitazone improves lipoatrophy in patients receiving thymidine-sparing regimens

OBJECTIVE

Thymidine reverse transcriptase inhibitors (tNRTI) are strong inhibitors of PPAR-gamma and clearly implicated as a cause of lipoatrophy. Thiazolidenediaones (TZD), potent PPAR-gamma agonists, would be expected to be beneficial in HIV lipoatrophy, but prior studies have been conflicting. None specifically excluded the use of tNRTIs. We report the first study in individuals treated with tNRTI-sparing regimens using a TZD for treatment of HIV lipoatrophy.

DESIGN

This double-blind, placebo-controlled study evaluated limb fat in HIV-infected individuals with lipoatrophy who discontinued tNRTI at least 24 weeks prior to enrollment.

METHODS

Individuals were randomized to rosiglitazone vs. placebo for 48 weeks. Dual energy X-ray absorptiometry (DEXA)-scans and fasting metabolic assessments were serially performed.

RESULTS

We enrolled 71 individuals, 17% were female and 51% white. Baseline characteristics were similar between groups except for higher total cholesterol in the placebo group (P = 0.04). At 48 weeks, limb fat (grams) increased significantly (P = 0.02) more in the rosiglitazone than in the placebo group: median (IQR) 448 (138, 1670) vs. 153 (-100, 682), respectively. Of lipids parameters, only total cholesterol increased significantly more in the rosiglitazone group (P = 0.008). Prevalence of metabolic syndrome and total bone mineral density did not change between or within groups.

CONCLUSION

In the absence of tNRTI, rosiglitazone significantly improves lipoatrophy without deleterious effect on bone mineral density. Total cholesterol, but not triglycerides, significantly increased in the rosiglitazone arm. The glitazones may be a promising addition for accelerating fat recovery in individuals who had switched off tNRTI and remain with significant lipoatrophy.

The phenomenology of body image in men living with HIV

Research into how people living with HIV or AIDS (PLWHA) experience and make sense of feared or actual body changes, such as lipodystrophy, is limited. The present study conducted in-depth interviews with gay men living with HIV. Interpretative phenomenological analysis (IPA) yielded themes across five domains. The ambiguity of early-stage lipodystrophy was a cause of distress. There was a drive to detect changes early, leading to anxiety, uncertainty and negative feelings about the body as well as possible misperception of change. In later stages, lipodystrophy was felt to be highly distinctive. Participants struggled to live with a shape that transgressed a body ideal. Feelings of loss of control were evident in both the increased ineffectiveness of strategies to maintain a desirable appearance and in the tendency for such changes to act as a visible marker of status. Conflicting feelings emerged in ideas of thinness and of health, with loss of fat seen as desirable in certain contexts. The study builds on previous research suggesting that the high value of appearance, particularly within gay communities, may lead to extreme compensatory behaviours. HIV places increased risk on a group highly vulnerable to body dissatisfaction and eating disorders. The study concludes with a cognitive-behavioural model of body image for PLWHA and suggestions for intervention. Further research is needed to validate the model and investigate whether the findings are generalisable. However, body image concerns should be acknowledged when addressing HIV-related health.

Subjective clinical lipoatrophy assessment correlates with DEXA-measured limb fat

OBJECTIVES

Although physician- and patient-rated diagnoses of lipoatrophy are currently used as a basis for inclusion into clinical trials, few studies have compared physician- or patient-rated lipoatrophy severity with objective measures. We aim to assess the validity of physician- and patient-rated diagnoses of lipoatrophy by evaluating the correlation between clinical assessments of lipoatrophy and objective fat indices.

METHODS

This cross-sectional study evaluated the association between clinical lipoatrophy scores and DEXA-measured limb fat (n = 154) and subcutaneous fat mitochondrial DNA (mtDNA) levels (n = 80) in HIV+ individuals.

RESULTS

There was a significant negative correlation between DEXA-measured limb fat and lipoatrophy scores generated by either the patients (r = -0.27, p = .008) or the physician (r = -0.48, p < .0001). Also, a significant positive correlation was found between the patient-generated lipoatrophy score and the physician score (r = 0.68, p < .0001). However, there was no correlation between fat mtDNA levels and DEXA-measured limb fat (r = -0.09, p = .42) or between physician- or patient-generated lipoatrophy scores (r = -0.09, p = .43, and r = 0.04, p = .71, respectively).

CONCLUSION

These results suggest that physician- and patient-rated lipoatrophy scores may be useful surrogates for more expensive measures of lipoatrophy, which could be reserved for research studies.

Four-year safety with polyacrylamide hydrogel to correct antiretroviral-related facial lipoatrophy

Infiltrations with synthetic substances are effective strategies for repairing facial lipoatrophy. However, few data are available on long-term safety. We describe the safety of polyacrylamide hydrogel in 145 patients who received facial infiltrations with Aquamid from September 2002 to April 2004. Epidemiological, clinical (mainly complications), and psychological data (patient satisfaction) were collected. We also recorded all patients who presented with a local infection at any time after receiving an infiltration. Sixty-two percent of patients presented with severe facial lipoatrophy before infiltration. The cumulative volume of Aquamid injected was 5.5 ml (4-18) per patient. During a mean (SD) of 50.2 (4.3) months after infiltration, only one patient presented with a local infection. Small palpable, nonvisible nodules or indurations were the most frequent complications (19.3% and 6.2%, respectively). If we include the remaining patients from our center (n = 294) who also received Aquamid (although less than 4 years ago), a further three patients presented with a local infection (incidence of 0.9%). Most patients (88.9%) were "satisfied" or "very satisfied" with the results; patients with mild to moderate baseline facial lipoatrophy were more satisfied than those with severe lipoatrophy ("very satisfied": 92.7% versus 86.5%, respectively). Only 17.4% reported mild impairment of lipoatrophy and only 9.2% required new infiltrations; however, 76% would have preferred more infiltrations. The high patient satisfaction and the low number of severe complications after at least 4 years of facial infiltrations with Aquamid reflect the long-term safety of this product for the repair of facial lipoatrophy. However, prolonged follow-up of these patients is recommended to detect unexpected long-term adverse reactions.

Lipoatrophy among HIV-infected patients is associated with higher levels of depression than lipohypertrophy

OBJECTIVES

We sought to determine the association between body morphology abnormalities and depression, examining lipoatrophy and lipohypertrophy separately.

METHODS

An observational cross-sectional study of 250 patients from the University of Washington HIV Cohort was carried out. Patients completed an assessment including measures of depression and body morphology. We used linear regression analysis to examine the association between lipoatrophy or lipohypertrophy and depression. Analysis of variance was used to examine the relationship between mean depression scores and lipoatrophy and lipohypertrophy in 10 body regions.

RESULTS

Of 250 patients, 76 had lipoatrophy and 128 had lipohypertrophy. Mean depression scores were highest among patients with moderate-to-severe lipoatrophy (16.4), intermediate among those with moderate-to-severe lipohypertrophy (11.7), mild lipohypertrophy (9.9) and mild lipoatrophy (8.5), and lowest among those without body morphology abnormalities (7.7) (P=0.002). After adjustment, mean depression scores for subjects reporting moderate-to-severe lipoatrophy were 9.2 points higher (P<0.001), scores for subjects with moderate-to-severe lipohypertrophy were 4.8 points higher (P=0.02), and scores for subjects with mild lipohypertrophy were 2.8 points higher (P=0.03) than those for patients without body morphology abnormalities. Facial lipoatrophy was the body region associated with the most severe depression scores (15.5 vs. 8.9 for controls; P=0.03).

CONCLUSIONS

In addition to long-term cardiovascular implications, body morphology has a more immediate effect on depression severity.

Severity of lipodystrophy is associated with decreased health-related quality of life

The impact of lipodystrophy (LD) on quality of life is high, but it has not been demonstrated in literature. The objective of the study was to assess the impact of LD on the health-related quality of life (HRQOL) in HIV-infected people on highly active antiretroviral therapy (HAART). Patients with LD phenotype defined by the Multicenter AIDS Cohort Study (MACS) were included. Three different methods were used to define LD severity: both patient and physician evaluation using the HIV Outpatient Study (HOPS) severity scales and the Lipodystrophy Case Definition (LDCD). The HRQOL was evaluated by MOS-HIV Health Survey. Four hundred one patients on HAART for a mean of 108 +/- 52 months were evaluated for LD at the Metabolic Clinic of Modena and Reggio Emilia University were enrolled from January 2003 to July 2006. According to self-perceived or physician-based HOPS, 106 (26.5%) and 122 (30.4%) patients had severe LD. Females had significantly more severe LD. Few HRQOL scores correlated to LD severity using the physician-based score (both HOPSph and LDCD), while all the HRQOL scores correlated with LD severity when a patient-based score was used (HOPSpt). In multiple linear regression analysis, Mental Health HRQOL score, gender, body mass index, age, body image satisfaction were independent predictors of patient-based (HOPSpt) LD, while none of the HRQOL scores, but female gender, age, waist-to-hip ratio, limb fat, and body image satisfaction were correlated with physician-estimated HOPSph LD severity. HRQOL was strongly correlated with LD severity when a patient-based score was used. For an overall assessment of the impact of LD on HIV-infected people, both patient-based and physician-based measures are required.

The impact of HIV-associated lipodystrophy on healthcare utilization and costs

Background

HIV disease itself is associated with increased healthcare utilization and healthcare expenditures. HIV-infected persons with lipodystrophy have been shown to have poor self-perceptions of health. We evaluated whether lipodystrophy in the HIV-infected population was associated with increased utilization of healthcare services and increased healthcare costs.

Objective

To examine utilization of healthcare services and associated costs with respect to presence of lipodystrophy among HIV-infected patients.

Methods

Healthcare utilization and cost of healthcare services were collected from computerized accounting records for participants in a body image study among HIV-infected patients treated at a tertiary care medical center. Lipodystrophy was assessed by physical examination, and effects of lipodystrophy were assessed via body image surveys. Demographic and clinical characteristics were also ascertained. Analysis of healthcare utilization and cost outcomes was performed via between-group analyses. Multivariate modeling was used to determine predictors of healthcare utilization and associated costs.

Results

Of the 181 HIV-infected participants evaluated in the study, 92 (51%) had clinical evidence of HIV-associated lipodystrophy according to physician examination. Total healthcare utilization, as measured by the number of medical center visits over the study period, was notably increased among HIV-infected subjects with lipodystrophy as compared to HIV-infected subjects without lipodystrophy. Similarly, total healthcare expenditures over the study period were $1,718 more for HIV-infected subjects with lipodystrophy than for HIV-infected subjects without lipodystrophy. Multivariate modeling demonstrated strong associations between healthcare utilization and associated costs, and lipodystrophy score as assessed by a clinician. Healthcare utilization and associated costs were not related to body image survey scores among HIV-infected patients with lipodystrophy.

Conclusion

Patients with HIV-associated lipodystrophy demonstrate an increased utilization of healthcare services with associated increased healthcare costs as compared to HIV-infected patients without lipodystrophy. The economic and healthcare service burdens of HIV-associated lipodystrophy are significant and yet remain inadequately addressed by the medical community.

HIV, AIDS, and sexuality

The purpose of this article is to outline information about people who live with HIV and AIDS and provide nurses with information on how to provide high-quality care for these patients related to sexuality and intimacy. This care is provided through a discussion of relationships, sexuality and sexual health, gender perceptions about sexuality, sexual needs and difficulties, and nursing assessment and intervention strategies.

Assessment of quality of life in HAART-treated HIV-positive subjects with body fat redistribution in Rwanda

Background

The introduction of HAART has initially improved the quality of life (QoL) of HIV-positive (HIV+) patients, however body fat redistribution (BFR) and metabolic disorders associated with long-term HAART use may attenuate this improvement. As access to treatment improves in sub-Saharan Africa, the disfiguring nature of BFR (peripheral atrophy and/or central adiposity) may deter treatment adherence and initiatives and decrease QoL. We examined the relationship between BFR and domains of QoL in HAART-treated HIV+ African men and women with (HIV+BFR, n = 50) and without (HIV+noBFR, n = 50) BFR in Rwanda.

Results

HIV+ subjects with BFR were less satisfied with their body image (4.3 ± 0.1 versus 1.5 ± 0.2; p < .001), self-esteem and social life (4.1 ± 1.4 versus 2.1 ± 0.3; p = 0.003). HIV+BFR were more ashamed in public (4.5 ± 1.2 versus 1.1 ± 1.1), reported less confident about their health (4.6 ± 1.4 versus 1.5 ± 1.2) and were frequently embarrassed due to body changes (4.1 ± 1.1 versus 1.1 ± 0.9) (p < .001) than HIV+noBFR. HIV+ Rwandan women with BFR reported more dissatisfaction with psychological (8.3 ± 2.9 versus 13.7 ± 1.9), social relationships (6.9 ± 2.3 versus 11.1 ± 4.1) and HIV HAART-specific domain of wellbeing (3.1 ± 4.8 versus 6.3 ± 3.6) (p < .001). Age was associated with independence (r² = 0.691; p = 0.009) and marital status was associated with psychological (r² = 0.593; p = 0.019) and social relationships (r² = 0.493; p = 0.007). CD4 count (r² = 0.648; p = 0.003) and treatment duration (r² = 0.453; p = 0.003) were associated with HIV HAART-specific domain of wellbeing. HIV+ Rwandan women with BFR were significantly more affected by abdominal adiposity (p < .001), facial and buttocks atrophy (p < .05) than HIV+ men with BFR.

Conclusion

Body fat alterations negatively affect psychological and social domains of quality of life. These symptoms may result in stigmatization and marginalization mainly in HAART-treated African women, adversely affecting HAART adherence and treatment initiatives. Efforts to evaluate self-perceived body fat changes may improve patients' wellbeing, HAART adherence and treatment outcomes and contribute towards stability in quality of life continuum.

Reconstructive treatment for antiretroviral-associated facial lipoatrophy: a prospective study comparing autologous fat and synthetic substances

Lipodystrophy is one of the foremost concerns among the HIV-positive population, and is often associated with psychosocial disorders. We evaluated the clinical efficacy of facial infiltrations with autologous fat, polylactic acid, and polyacrylamide gel using clinical inspection and facial photographs (ordinal scale). Additionally, we assessed the safety of the infiltration techniques and determined changes in patient satisfaction, emotional status, and quality of life. Evaluations were made at 48- and 96-week follow-up visits. This paper presents the 48- week follow-up results. The current analysis includes 138 patients: 8, 25, and 105 in the fat, polylactic acid, and polyacrylamide gel groups, respectively. At baseline, almost 50% of the patients (67/138) presented grades 3 and 4 lipoatrophy, but at week 48 only 7.5% (7/93) remained in these advanced grades (no patients from the polyacrylamide group). A new round of infiltrations at week 48 was necessary in 35% (33/93) of patients (88%, 84%, and 8% in the fat, polylactic, and polyacrylamide groups, respectively). No serious adverse events were detected with any of the substances. Patient satisfaction and quality of life improved significantly in all three groups. Infiltrations with autologous fat, polylactic acid, or polyacrylamide gel appear to be an effective and safe alternative to repair facial lipoatrophy, at least up to 48 weeks, significantly improving patient quality of life. Similar results were observed for all degrees of severity and between genders. Polyacrylamide gel provided the longest lasting benefits.

Uncertainty and 'technological horizon' in qualitative interviews about HIV treatment

Highly Active Anti-Retroviral Treatment (HAART) has reduced death and morbidity among people with HIV. However, HAART is not always effective, can produce serious side-effects and implies uncertainty for patients. To address HAART-related uncertainty, 20 qualitative interviews were conducted with gay men with HIV in Glasgow and London. The interviewees were purposively selected to reflect diversity in terms of year of diagnosis, experiences of illness and treatment-related side-effects. The interviews were analysed using the constant comparison method to derive themes. Among those using HAART, analysis identified themes of 'good health', 'illness' and 'loss of confidence'. Uncertainty was managed through a discourse of 'technological horizon' that combined the ongoing innovations of HAART and biographical time. These themes are discussed in terms of the implications for HIV care. In particular, technological horizon provides a basis for the management of uncertainty in the prescribing relationship between patient and clinician.

Safety and Efficacy of Poly-l-lactic Acid Injections in Persons with HIV-Associated Lipoatrophy: The US Experience

BACKGROUND

With the introduction of highly active antiretroviral therapy (HAART), HIV/AIDS has become a more chronic disease. This increase in survival, however, has been accompanied by the occurrence of metabolic and morphologic changes known collectively as HIV-associated lipodystrophy.

OBJECTIVE

The objective was to evaluate the quantifiable improvement in facial wasting (lipoatrophy) after serial injections of poly-L-lactic acid (PLLA) as well as the long-term safety and durability of this material.

METHODS AND MATERIALS

A single-site, open-label study in which patients received up to six treatment sessions of injectable PLLA. Patients were followed for 12 months after treatment. Patients were evaluated for increase in total cutaneous thickness by skin calipers. Serial photographs and patient satisfaction and patient well-being questionnaires were undertaken throughout the study period.

RESULTS

Patients at the end of treatment exhibited a mean increase in skin thickness of 65.1% compared with baseline values. This correction was maintained throughout the 12-month follow-up period (68.8% at 6 months and 73% at 12 months). On a one to five scale, patient satisfaction was 4.5 at the end of treatment and increased to 4.8 at 12-month follow-up. No serious adverse events were reported.

CONCLUSION

PLLA is a safe and well-tolerated treatment option for HIV-associated lipoatrophy.

Body image in men with HIV

OBJECTIVE

To determine body image among HIV-infected men and to determine the relationship of lipodystrophy on body image.

METHODOLOGY

Self-report questionnaires on body image were distributed to HIV-infected men at the university-based HIV clinic. Two previously validated instruments, the Body Image Quality of Life (BIQLI) scale and the Situational Inventory of Body Image Dysphoria Short Form (SIBID-S) were used to measure body image effects. The presence of lipodystrophy was determined by both self-report and physician examination. Demographic characteristics, disease stage, health status, and quality of life were also ascertained. Analysis of responses was performed via both group comparisons and linear regression analyses.

RESULTS

One hundred ten men responded. Seventy-one percent identified their sexual orientation as men having sex with men (MSM). Forty-eight reported the presence of lipodystrophic characteristics; 62 reported no lipodystrophic changes. Agreement regarding the presence of lipodystrophy between physician and subject was 0.80 as measured by the kappa coefficient of agreement. Compared to HIV-infected men who denied lipodystrophy, HIV-infected men with self-reported lipodystrophy demonstrated poor body image as measured by BIQLI (p < 0.0001) and SIBID-S scales (p = 0.0001). Similarly, physician rated lipodystrophy was significantly associated with both body image subscale scores.

CONCLUSIONS

We demonstrate that lipodystrophy among HIV-infected men is associated with poor body image.

Full scope of effect of facial lipoatrophy: a framework of disease understanding

BACKGROUND

Facial lipoatrophy has been observed to occur in a variety of patient populations, with inherited or acquired disease, or even in aging patients as a natural progression of tissue change over time. There is currently no framework from which physicians of all medical specialties can communally discuss the manifestations, diagnoses, and management of facial lipoatrophy.

OBJECTIVE

The aim of this assembly was to derive a definition of facial lipoatrophy capable of being applied to all patient populations and develop an accompanying grading system.

RESULTS

The final consensus of the Facial Lipoatrophy Panel encompasses both aging and disease states: "Loss of facial fat due to aging, trauma or disease, manifested by flattening or indentation of normally convex contours." The proposed grading scale includes five gradations (Grades 1-5; 5 being the most severe), and the face is assessed according to three criteria: contour, bony prominence, and visibility of musculature.

CONCLUSION

Categorizing the presentation of facial lipoatrophy is subjective and qualitative, and will need to be validated with objective measures. Furthermore, during the assembly, several topics were exposed that warrant further research, including the physiology of volume loss, age and lipoatrophy, and human immunodeficiency virus and lipoatrophy.

Multidisciplinary approach to the treatment of metabolic and morphologic alterations of HIV-related lipodystrophy

BACKGROUND

Treatment for metabolic and morphologic alterations in HIV-related lipodystrophy include medical therapy, physical exercise, and surgical interventions.

METHOD

We assessed the efficacy and safety of a comprehensive multidisciplinary approach for treating morphological and metabolic alterations of the lipodystrophy syndrome in consecutive patients attending the Metabolic Clinic (MC) of the University of Modena and Reggio Emilia who had at least 2 evaluations over a 48-week period. 245 patients were evaluated: 143 (62.4%) were men, 74 (36.1%) presented with lipoatrophy, 10 (4.9%) with fat accumulation, 93 (45%) with mixed forms, 24 (11.3%) had hypercholesterolemia (LDL >160 mg/dL), 87 (38%) had hypertriglyceridemia (TG >150 mg/dL), 13 (5.7%) had diabetes (glucose >126 mg/dL), and 78 (44%) had insulin resistance (HOMA-IR >4).

RESULTS

At follow-up, a significant improvement was observed in both objective and subjective variables. Anthropometric improvement was observed in waist to hip ratio, waist circumference, and right and left cheek dermal thickness measurements. A nonsignificant improvement was observed in fat and lean regional mass by DEXA; CT showed improvement in visceral and subcutaneous adipose tissue. Glucose, HOMA-IR, total cholesterol, and APO B improved. Subjective variables improved in aesthetic satisfaction.

CONCLUSION

We conclude that the medical and surgical interventions proposed in this multidisciplinary therapeutic approach are efficacious and safe in the management of lipodystrophy.

Effects of lipodystrophy on quality of life and depression in HIV-infected men on HAART

The aim of the study was a prospective assessment of the possible consequences of a diagnosis of lipodystrophy on health-related quality of life (HRQL) and depressive symptomatology in HIV-seropositive men who have sex with men. A standardized physical assessment for lipodystrophy was introduced within a prospective study in April 1999. Over a 2-year follow- up, 37 HIV-seropositive men who met the criteria for lipodystrophy were longitudinally compared to 92 HIV-seropositive men without lipodystrophy and 88 HIV-seronegative men on measures of HRQL and depression. A series of questionnaires, which included the Medical Outcomes Study Short-Form 36 (SF-36) and the Center for Epidemiological Studies-Depression (CES-D), were administered to assess HRQL and depression, respectively. SF-36 scores were summarized using the mental and physical components; CES-D results were reported as both dichotomous (with or with clinical depression) and continuous scores. Neither the mental nor physical components of the SF-36 showed any significant differences between patients with lipodystrophy versus HIV-seropositive patients without lipodystrophy. Similarly, lipodystrophy status was not significantly associated with either continuous depression scores or presence of clinical depression. However, consistent with previous results, HIV-seropositive men without lipodystrophy (compared to HIV-seronegative men) reported higher scores on both components of the SF-36 scales and both categorizations of the CES-D. The results of this study suggest that lipodystrophy does not negatively affect HRQL or depression, above and beyond, the diagnosis of HIV infection, although the impact of the severity of lipodystrophy on these conditions will require further study.

Body image in women with HIV: a cross-sectional evaluation

BACKGROUND

HIV lipodystrophy syndrome is a recognized complication of potent antiretroviral therapy and is characterized by often dramatic changes in various body fat stores, both central and peripheral. Given prior findings of heightened body image dysphoria among HIV-infected men with lipodystrophy as compared to HIV-infected men without lipodystrophy, we sought to determine body image among HIV-infected and HIV-negative women and to determine the relationship of HIV and lipodystrophy with body image. Our a priori hypothesis was that women with HIV and lipodystrophy would have significantly poorer body image as compared to women without HIV and to women with HIV without lipodystrophy.

RESULTS

116 women responded to two previously validated self-report instruments (Body Image Quality of Life Index (BIQLI) and the Situational Inventory of Body-Image Dysphoria-Short Form (SIBID-S)) on body image. 62 (53% subjects) HIV-infected women were recruited at the university-based HIV clinic. 54 (47% subjects) HIV-negative female controls were recruited from another study evaluating bone density in otherwise healthy controls. 96% identified their sexual orientation as women having sex with men. Among the HIV-infected group, 36 reported the presence of lipodystrophic characteristics and 26 reported no lipodystrophic changes. Agreement regarding the presence of lipodystrophy between physician and subject was 0.67 as measured by the kappa coefficient of agreement. Compared to HIV-negative women, HIV-positive women demonstrated poor body image as measured by BIQLI (p = 0.0009). Compared with HIV-infected women who denied lipodystrophy, HIV-infected women with self-reported lipodystrophy demonstrated poor body image as measured by BIQLI (p = 0.02) and SIBID-S scales (p = 0.001).

CONCLUSION

We demonstrate that HIV and lipodystrophy status among women is associated with poor body image. Universal efforts should be made in the HIV medical community to recognize body image issues particularly among persons affected by lipodystrophy so that appropriate intervention and support may be provided.

Correction options for lipoatrophy in HIV-infected patients

Lipoatrophy (LA) is a form of lipodystrophy, characterized by volume depletion caused by fat loss in the limbs, buttocks, and face. Facial volume loss is the most obvious outward sign of LA because it alters the facial contours in the cheeks, temples, and orbits. Lipodystrophy and LA are most commonly seen in patients with HIV on highly active antiretroviral therapy (HAART), which was introduced in the mid-1990s for the management of HIV, and is currently considered the mainstay therapy for HIV-infected patients. However, the etiology of LA is likely multifactorial as underlying patient conditions, including duration and severity of HIV and increasing age, have also been found to contribute to its occurrence. The volume loss of LA can be very dramatic with some patients exhibiting no signs of facial fat. As a result, many HIV-infected patients with associated LA suffer from psychological and lifestyle effects, which can lead to noncompliance with HAART. Thus, increases in facial volume and improvement in morphology is anticipated to reduce anxiety caused by LA in HIV-infected patients, and improve quality of life. This review discusses the benefits and limitations of several treatment options available to correct the volume depletion associated with LA, including antiretroviral switching, permanent surgical implants and injectables, poly-L-lactic acid, collagen, and hyaluronic acid derivatives.

Quality of Life and Body Image in the Assessment of Psychological Impact of Lipodystrophy: Validation of the Italian Version of Assessment of Body Change and Distress Questionnaire

Lipodystrophy (LD) includes morphologic changes that are distressing to patients with HIV. We tested the validity of an Italian version of the Assessment of Body Change and Distress (ABCD) questionnaire and analysed its relationship to physical and mental aspects of Health-Related Quality of Life. Two hundred and fifty-two patients completed the questionnaires. Construct validity of the ABCD was tested against the MOS-HIV Health Survey, body mass-index (BMI) and CD4+ T-lymphocyte counts. Cronbach's alpha for the ABCD total score was 0.94. The ABCD showed the hypothesized moderate correlations to MOS-HIV scales and clinical variables. Preliminary evidence supports the reliability and validity of the Italian version of the ABCD in people with HIV and LD. This questionnaire may be useful to identify people experiencing greater impact of LD, or to evaluate the impact of interventions to treat LD such as plastic surgery.

Caring for HIV-positive and aging patients with associated facial lipoatrophy

Facial lipoatrophy is characterized by fat loss and redistribution. It is a natural, biological phenomenon that occurs over time, presenting as mild-to-moderate volume depletion that gives the skin the appearance of sagging. More recently, highly active antiretroviral therapy, introduced for the management of human immunodeficiency virus, has been associated with moderate-to-severe facial lipoatrophy, and is characterized by sunken cheeks, accentuated nasolabial folds, and protruding musculature and bones. Furthermore, the consequences of facial lipoatrophy have been found to substantially impact patient quality of life. Nurses play an integral role in the treatment of facial lipoatrophy by educating the patients on available therapies and assisting them in making informed treatment decisions. It is important that treating nurses conduct a well-organized interview to understand patient treatment goals. This article will discuss several treatment options available to correct facial lipoatrophy-associated volume deficits, including collagen, hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, and permanent implants and injectables.

[Quality of life in HIV-infected children and adolescents under highly active antiretroviral therapy: change over time, effects of age and familial context]

OBJECTIVE

To evaluate Quality of life (QoL) of HIV-infected children under highly active antiretroviral therapies, and its change over 18 months.

MATERIALS AND METHODS

QoL was evaluated by self-administred questionnaires (french versions of AUQUEI, OK-ado, and compilation of both) in 23 young living with HIV/AIDS (6-15 yrs), under antiretroviral multitherapies, and re-evaluated 18 months later in 19 of them.

RESULTS

At baseline, QoL in HIV-infected children-adolescents was relatively good. The answers given to each items and the mean score from infected children were similar to those obtained in uninfected healthy children. Moreover, infected adolescents distinguished definitly from healthy adolescents, describing higher QoL. The mean satisfaction score from the whole group decreased between M0 and M18 (mainly in the youngests), and mainly concerned 3 fields (self-esteem, health and school) while their somatic health remained stable or improved. An effect of the familial context was also observed for these 3 fields.

CONCLUSION

The progressive decline of QoL in HIV-infected children, and the surprising high and steady level of satisfaction over-time provided by the adolescents, underlined the frailty of this population and the need for a psychologic management associated to the medical follow-up. Such a multidisciplinary approach should take into account the preoccupations and difficulties of each age-class, those linked to the diagnosis itself, and to the familial or scolar contexts, in order to preserve QoL of this pediatric population, as far as possible, in a long term.

Sex and relationships for HIV-positive women since HAART: a qualitative study

There is little available on HIV-positive women's sexual relationships other than within-risk behavior paradigms. Increased life expectancy with the advent of highly active antiretroviral therapies (HAART) may increase the opportunity for women to develop sexual relationships. This study investigates sexual functioning in HIV-positive women and presents the analysis of interviews with 21 seropositive heterosexual women (age range, 22-54). Fourteen (67%) were black African, 6 (29%) white European, and 1 (5%) "other." Thirteen (62%) were currently or had been sexually active since becoming aware of their diagnosis. Dominant themes identified included: (1) difficulties with sexual functioning, in particular lowered libido and enjoyment and reduced intimacy; (2) barriers to forming new relationships: fears of HIV disclosure, fears of infecting partners; (3) coping strategies: included relationship avoidance and having casual partners to avoid disclosure; (4) safer sex: personal dislike of condoms, lack of control, lack of suitable alternatives. Women are experiencing a range of sexual and relationship difficulties that appear to be relatively unchanged despite the advent of HAART. Culturally appropriate, focused psychosexual and couples work should be more readily available for women living with HIV and their partners.

Antiretroviral Therapy in HIV-Infected Children: The Metabolic Cost of Improved Survival

Although highly active antiretroviral therapy (HAART) has positively altered the morality rates in HIV-infected children, these drugs have the potential to cause significant morbidity. These drugs cause changes in fat distribution, lipid profiles, glucose, homeostasis, and bone turnover. The direct relationship between duration of drug exposure and increased risk of cardiovascular disease is particularly concerning for HIV-infected infants and children, who likely will have longer cumulative exposure to HAART. It is unclear whether the metabolic effects of decades of exposure would be reversible with cessation of therapy. The benefits of HAART in HIV infection are indisputable, but the impetus to find a cure or design more tolerable therapy is clear. Infarction may replace infection as the major cause of morbidity and mortality from HIV.

The relationship between lipodystrophy-associated body changes and measures of quality of life and mental health for HIV-positive adults

OBJECTIVES

To investigate the relationship between lipodystrophy-specific symptom severity and wellbeing.

METHODS

HIV-positive adult patients with body fat redistribution (lipodystrophy syndrome) associated with antiretroviral therapy reported their total non-lipodystrophy symptoms and side effects and completed measures assessing body fat changes (yielding Atrophy, Hypertrophy and Total Lipodystrophy scores), mental health and quality of life. Effects of total symptom complex and lipodystrophy severity on quality of life and mental health were analyzed using Spearman's rho correlations. Logistic regression analyses were utilized to determine the relative-odds of depression produced by overall symptom count and lipodystrophy score increments.

RESULTS

Mean ratings for Hypertrophy and Atrophy corresponded to 'very mild' and 'mild' degrees of severity, respectively. The total symptom complex was associated with ratings for most of the mental health and quality of life measures. Patient-perceived body image scores were the sole study variable responsive to lipodystrophy severity ratings. In comparison to reference norms, a pronounced degree of body image impairment was evident.

CONCLUSION

Although responsive to the total symptom profile, psychosocial measures typically utilized for evaluating quality of life and mental health status in HIV disease lacked sensitivity and specificity for measuring the consequences of lipodystrophy-associated fat distribution changes alone. Lipodystrophy severity did impact negatively on body image.

Body image in patients with HIV/AIDS: assessment of a new psychometric measure and its medical correlates

HIV infection and its treatment can have significant effects on physical appearance and functioning, which can affect self-perceived body image. We assessed the psychometric properties of a newly developed Body Image Scale (BIS), a subjective measure of body image perception in persons with HIV infection, as well as the scale's relationship to disease progression, symptoms, and demographic factors. HIV-positive men (n = 129) and women (n = 21) attending two outpatient HIV clinics were administered the BIS survey along with a one-page questionnaire. A subset (n = 38) were administered the survey on two occasions to assess test-retest reliability. Nearly half of the sample (46%) had AIDS and 25% had a CD4 count below 200 cells/mm(3) within the prior 3 months. The BIS had unidimensional factor structure, good internal consistency reliability (Chronbach alpha = 0.91), and good test-retest reliability (r = 0.71, p < 0.001) after controlling for the length of interval between assessments. Patients' current perception of their body image was worse then what they perceived it to be prior to HIV infection (p < 0.001), but better than their perception of how others view people with HIV (p < 0.001). The presence of symptomatic disease (p < 0.001) and a diagnosis of AIDS (p = 0.02) were associated with a less favorable body image, although laboratory markers of disease progression (CD4 count and plasma HIV viral load) were not. We conclude that the BIS has good construct validity and is a highly reproducible measure of self-perceptive of body image in HIV-infected patients. Further exploration of its relationship to psychological well being, medication adherence and other aspects of medical care is indicated.

Sexuality and sexual risk behavior in HIV-positive men who have sex with men

The purpose of this study was to examine the psychological processes pertaining to sexuality and sexual risk behavior among HIV-positive men who have sex with men (MSM). The authors analyzed transcripts of 30 semistructured interviews. Findings suggest that sexual problems in HIV-positive MSM might be primarily caused by the perceived risk of transmitting HIV to others. Furthermore, safer sexual behavior seems to be related to feelings of personal responsibility for safer sex. This study illustrates that although some men might have a clear notion of personal responsibility for safer sex, contextual factors can influence whether behavior is consistent with their norms of personal responsibility. The implications of the study are discussed for the practice of HIV prevention for HIV-positive MSM.

Suction-assisted lipectomy for lipodystrophy

Lipodystrophy resulting from HIV disease or the antiretroviral therapy used to treat it is a common complication. We report on the treatment of cervical lipohypertrophy ("buffalo hump") with suction-assisted lipectomy in six patients.

Factors Associated with Severe Impact of Lipodystrophy on the Quality of Life of Patients Infected with HIV-1

A standardized questionnaire was used to assess the impact of lipodystrophy (LD) on quality of life (QoL). Eighty-four consecutive asymptomatic human immunodeficiency virus type 1 (HIV-1)-infected outpatients with clinical LD completed a modified version of the Dermatology Life Quality Index (DLQI) survey to measure the impact of body fat changes on their QoL. Body changes influenced dressing for 55 patients (65%), produced feelings of shame for 41 (49%), and disrupted sexual life for 23 (27%). There was a greater impact on the DLQI due to body changes among women, injection drug users, patients with abdominal or breast lipoaccumulation, and patients with a high number of non-LD side effects. Multivariate proportional odds model analysis showed that the severity of non-LD-associated side effects and the presence of breast lipoaccumulation were associated with impaired psychosocial functioning. Specific characteristics of patients, antiretroviral-based side effects, and breast lipoaccumulation exert a greater impact on QoL in HIV-1-infected patients with LD.

Effect of antioxidants on glucose metabolism and plasma lipids in HIV-infected subjects with lipoatrophy

Ten HIV-infected nucleoside reverse transcriptase inhibitor-treated subjects with lipoatrophy or sustained hyperlactatemia were given antioxidants: vitamins C, E, and N-acetyl cysteine. After 24 weeks, anthropometrics did not change significantly, except for a modest decrease in the waist-to-hip ratio. Fasting low-density lipoprotein cholesterol trended toward lower values. Fasting glucose significantly increased along with a significant increase in homeostatic model assessment values, reflecting an increase in insulin resistance. Controlled trials are required to evaluate directly the effects of these agents on lipid and glucose metabolism.

A qualitative study of the psychosocial implications of lipodystrophy syndrome on HIV positive individuals

OBJECTIVES

To investigate the psychosocial impact of lipodystrophy on the lifestyles of HIV positive patients on highly active antiretroviral therapy (HAART).

METHODS

In-depth interviews were conducted with 14 HIV positive patients on HAART at an outpatient sexually transmitted infections (STI) and HIV clinic in central London. Qualitative data from interview transcripts were analysed using grounded theory to elicit key categories and subcategories.

RESULTS

Three main themes relating to lipodystrophy emerged: effect on the individual; impact on the social world of the individual; responses of the individual. Lipodystrophy had physical and psychological effects, ranging from bodily discomfort to low self esteem and depression. Owing to its physical manifestations it was viewed as a visible marker of HIV disease. At the level of social functioning, lipodystrophy led to problems with personal and family relationships, although having a partner was protective. Individuals reported narrowing their social world, in some cases to degrees of social isolation. Individual responses included changes in diet, increased exercise regimes, steroid use and plastic surgery (mainly collagen injections to the face). For those who had experienced serious illness related to HIV, there was a more sanguine acceptance of lipodystrophy as an unfortunate consequence of longevity and drug therapy

CONCLUSIONS

Health professionals need to address the psychosocial implications of lipodystrophy, including the ways in which it may affect different groups and their adherence to therapy. Formative evaluations are needed to assess the potential for targeted interventions.

Metabolic complications of antiretroviral therapy in children

Survival in HIV-infected children has greatly improved with the introduction of highly active antiretroviral therapy. Children are more vulnerable than adults to metabolic side effects of therapy because of its potential impact on growth and the children's likely greater cumulative exposure. This review summarizes the epidemiology and management of lipodystrophy, dyslipidemia, insulin resistance, hyperlactatemia, osteopenia and growth failure in HIV-infected children.

Impact of lipodystrophy on the quality of life of HIV-1-infected patients

INTRODUCTION

Lipodystrophy (LD) represents an important problem for HIV-1-infected patients receiving highly active antiretroviral therapy (HAART), although its impact on quality of life (QoL) has not been properly studied.

DESIGN

Cross-sectional, nonrandomized, observational study performed on consecutive, clinically stable outpatients taking HAART for more than 1 year.

METHODS

Data on patients' characteristics, HIV-1 infection, treatment adherence and adverse effects, overall QoL measured by the Profil der Lebensqualität Chronischkranker (PLC), and the presence of LD defined by clinical criteria were assessed.

RESULTS

Eighty-four (56%) of 150 interviewed patients fulfilled criteria for LD. Patients with LD were older, had been taking antiretroviral treatment longer, and reported a poorer physical status than patients without LD. Surprisingly, LD itself was not found to influence overall QoL. However, homosexual patients, unemployed patients, and those patients undergoing current psychiatric treatment showed greater impairment on some of the QoL subscales related to psychological well-being if they suffered from LD.

CONCLUSION

The impact of HIV-related LD on QoL depends on certain patient characteristics, rather than on the presence of LD itself.

Intentional nonadherence due to adverse symptoms associated with antiretroviral therapy

OBJECTIVE

To estimate the frequency and possible predictors of patient-mediated intentional alterations in antiretroviral medication regimens in direct response to symptoms associated with antiretroviral therapy use.

DESIGN

Cross-sectional survey of a population-based dynamic cohort of antiretroviral recipients in a province-wide HIV drug treatment program, the only source of free-of-charge antiretroviral medications in the province of British Columbia.

METHODS

Program participants voluntarily complete program surveys on an annual basis. Study subjects were those who responded to the annual treatment program survey between January 1 and November 1, 2001. Patients reported on the occurrence and severity of symptoms of 42 side effects of antiretroviral agents. Symptoms were classified into four subgroups based on whether they were considered subjective or objective and whether they would or would not prompt clinical action. For each of the four symptom categories, patients reported what their physician recommended in response to symptoms in that group and what the patient actually did in response to these same symptoms. Intentional nonadherence was defined as reporting either skipping or altering dosages of selective regimen components or temporary cessation of therapy that was not recommended by the physician in response to adverse drug effects in the past year.

RESULTS

Of 638 study subjects, 70 (11%) reported intentional nonadherence with between 4% and 7.4% reporting this activity over the preceding year depending on the symptom group. Multivariate analysis revealed that a plasma viral load of <400 copies/mL (adjusted odds ratio [AOR], 0.35; 95% CI, 0.21-0.61) and completion of high school (AOR, 0.43; 95% CI, 0.24-0.78) were both inversely associated with intentional nonadherence. Those subjects reporting at least one severe symptom were more than twice as likely to report intentional nonadherence (AOR, 2.24; 95% CI, 1.16-4.33). Similarly, each additional symptom considered to be objective and to require clinical action was associated with a 25% increase in the risk of intentional nonadherence (AOR, 1.25; 95% CI, 1.10-1.43).

CONCLUSION

Intentional nonadherence to antiretroviral therapy is common among persons experiencing therapy-related side effects. Although the type and severity of adverse effects impact intentional nonadherence, this activity occurs in relation to symptoms regardless of their strict clinical relevance.

Lipodystrophy syndrome and self-assessment of well-being and physical appearance in HIV-positive patients

The lipodystrophy syndrome (LDS) is a growing problem in human immunodeficiency virus (HIV)-positive patients treated with highly active antiretroviral therapy (HAART). It is characterized by alterations of body composition and metabolic abnormalities. The goal of the study was to investigate attitudes toward health condition, well-being, and individual appearance in relation to LDS. Outpatients between July and October 2000 in an HIV-specialized unit at the University Hospital of Düsseldorf, Germany, underwent clinical evaluation and received a standardized written questionnaire. Of 389 patients eligible for analysis, 313 patients returned completed questionnaires (response rate, 80.5%). LDS was observed in 37.7%; the predominant manifestation was lipoatrophy of the face (32.9%). Individuals with and without LDS did not differ significantly in their attitude to the quality of their health condition and the amount of disturbance of their well-being by HIV infection. Participants with LDS felt recognizable as HIV-positive by physical appearance in 30.1%, compared to 18.3% in patients without LDS (p = 0.027). This difference became more pronounced after adjustment for gender, age, stage of disease, CD4 cell count, and duration of HAART (odds ratio, 2.04, 95%-confidence interval [CI] 1.09-3.84). In conclusion, LDS does not seem to disturb the general attitude toward health condition and well-being. However, patients presenting with lipodystrophy are about twice as likely to feel recognizable as HIV-positive by their physical appearance. LDS may thus be perceived as a characteristic mark of being HIV-positive by affected persons. A stigmatizing effect and social disadvantages may be the consequences.

Strategies for treating HIV-related lipodystrophy

HIV-related lipodystrophy has emerged as one of the most prevalent problems for patients with HIV, since this infection can now be seen as a chronic disease. Despite its growing importance, crucial issues such as aetiopathogenesis, diagnosis, prevention and therapy remain largely unknown and unexplored. Current evidence suggests that aetiology is multifactorial. HIV infection, antiretroviral therapy and patient-related factors probably all contribute to the development of lipodystrophy. The lack of a formal definition and the nature of wasting syndromes that affect HIV-infected patients can hinder the diagnosis and treatment of lipodystrophy. Body fat changes have a major negative impact on the quality of life of patients. Metabolic abnormalities are also well known cardiovascular risk factors that can increase the morbidity and mortality due to cardiovascular disorders in a relatively young population. As yet, we do not know whether lipodystrophy is preventable or reversible. Several therapeutic approaches have been tested with limited success, however potential complications must be considered. These therapeutic approaches include general health measures (diet, exercise and discontinuation of smoking), switching antiretrovirals (from protease inhibitors to non-nucleoside reverse transcriptase inhibitors or abacavir, or from stavudine to other nucleoside reverse transcriptase inhibitors) and use of drugs with metabolic effects (metformin, thiazolidinediones, recombinant growth hormone and anabolic steroids). A judicious use of available data, and opting for an individualised approach seems the best option for management of this problem at present.
