Lipodystrophy in HIV/AIDS patients with different levels of physical activity while on antiretroviral therapy

Relationship of handgrip strength with health indicators of people living with HIV in west Pará, Brazil

BACKGROUND

Handgrip strength (HGS) is an important health indicator that can be influenced by body composition and biochemical markers of people living with HIV, contributing to better understanding of health-related outcomes.

OBJECTIVE

To analyze the relationship between HGS and health indicators in people living with HIV.

METHODS

Cross-sectional study, with 207 people living with HIV, attending a reference center, located in Santarém, Pará, Brazil. Data collection covered sociodemographic, clinical, laboratory, physical activity level, body composition, and HGS information. Data were analyzed using descriptive and inferential statistics, adopting p < .05.

RESULTS

There was a predominance of men (60%), aged 33-47 years (42%). A relationship was observed between adequate HGS and the male sex (p < .001), and adequate values for body mass index (p = .003), abdominal circumference (p < .001), and total cholesterol (p = .012). In addition, higher values of fat mass (p < .001), and lower lean mass (p = .006) were observed for people living with HIV with low HGS.

CONCLUSION

People living with HIV present an association between lean body mass and high HGS. On the other hand, low HGS favored obesity and hypercholesterolemia. Thus, monitoring HGS is an important indicator of body, laboratory, and functional capacity changes, with HGS being an additional element in the clinical evaluation.

Inflammatory and Cardiovascular Correlates of Physical Activity and Sedentary Behavior in Older Adults Living With HIV

BACKGROUND

Inflammation is an indicator of oxidative stress that may contribute to cardiovascular diseases in older people living with HIV (OPWH). Physical activity (PA) may reduce these biomarkers in OPWH, but little is known about the association of PA with inflammatory and cardiovascular biomarkers. We sought to examine the inflammatory and cardiovascular biomarker correlates of PA and sedentary behavior in OPWH.

METHODS

We included 101 OPWH with complete assessments of PA, sedentary behavior, and biomarker data to examine the association between the volume of PA and inflammatory and cardiovascular biomarkers.

RESULTS

In this cohort of OPWH (mean age 55.9 y), 68% were male and 83% were African American/Black. Among OPWH, greater volume of PA (ie, walking, moderate, vigorous, and/or total) was associated with lower systolic (P < .05) and diastolic blood pressure (P < .05), pulse pressure (P < .05), and tumor necrosis factor-alpha (P < .05). Greater duration of sitting was associated with greater triglycerides, interleukin-6, and tumor necrosis factor-alpha (P < .05).

CONCLUSIONS

Although adherence to regular PA among OPWH is low and sedentary behavior is high, the associations between biomarkers and PA suggest a greater volume of PA could attenuate the inflammatory and cardiovascular derangements experienced by OPWH.

HIV infection in the west region of Pará

Aims: knowledge of the patient’s profile, for the evaluation and suggested behaviors, promotes a favorable outcome. Thus, the objective of the study is to analyze the socioeconomic, clinical, and immunological characteristics of patients infected by the human immunodeficiency virus in the western region of the state of Pará.Methods: were analyzed 1966 medical records of patients whose first visit to a reference center, in the municipality of Santarém-PA, was between 1998 and 2018. Socioeconomic, clinical, and immunological information was collected from patient medical records. Data were analyzed using descriptive and inferential statistics, adopting p <0.05.Results: there was a predominance of males (62.5%), aged 20-39 years (69.1%), elementary school (58.6%), single (57.3%), and employed (66.4%). Immunosuppression was present in 22% of patients and a viral load was detectable in 66%. Tuberculosis (37%) and toxoplasmosis (23%) predominated as opportunistic infections, and syphilis (62.6%) and human papillomavirus (HPV; 14%) as other infections.Conclusions: it is concluded that both opportunistic infections and other infections were present in 25-22% of the patients and that the presence of opportunistic infections favors the installation of another infection, or vice versa. Toxoplasmosis, HPV, and syphilis are positively associated with men, and toxoplasmosis and tuberculosis with age >35 years. Immunosuppression was shown to be positively associated with men and age >35 years, as well as favoring the onset of tuberculosis, toxoplasmosis, and detectable viral load.

Concurrent training remodels the subcutaneous adipose tissue extracellular matrix of people living with HIV: a non-randomized clinical trial

Evaluate the effect of 12wks of concurrent training (CT) in extracellular matrix (ECM) of subcutaneous adipose tissue (SAT) in people living with HIV/aids (PLWHA). To the non-randomized clinical trial 19 participants, 11 healthy (HIV-) and 18 PLWHA under the use of highly active antiretroviral therapy (HAART) for at least 1 year (HIV+). All participants engaged in a moderate-intensity CT program for 12 weeks, three times a week. Before and after CT, aerobic and strength performance were assessed, as well as anthropometry and biochemical blood profile. Also, SAT biopsies were carried out for histologic and morphometric analysis. The statistical analysis was carried out with R Studio, using descriptive and inferential analysis, ANOVA test and mixed-effect model were utilized (P<0.05). HIV+ showed higher levels of VLDL, TGL, and lower levels of HDL in baseline than HIV- (P<0.05). All groups improved aerobic and strength performance (P<0.05). Both groups presented reduced adipocyte sizes after CT (P<0,05). Lastly, HIV+ presented smaller adipocytes and higher elastic fiber deposition in baseline and decreased after training only in HIV+, matching similarly to HIV- group. Thus, CT in PLWHA promoted a decrease in size heterogeneity of adipocytes and elastic fiber deposition, remodeling ECM and improving SAT fibrosis profile. Brazilian Clinical Trials Registry (UTN: U1111-1214-3022) Novelty • Adipose tissue fibrosis is improved by training in people living with HIV. • Concurrent training remodels adipose tissue extracellular matrix.

Physical activity levels among Malawian adults living with HIV and receiving anti-retroviral therapy

Introduction

Despite increasing life expectancy among people living with HIV (PLWHIV), anti-retroviral therapy (ART) side effects, HIV chronic inflammation and co-morbidities may limit functional abilities and reduced participation in exercises and physical activity (PA). PA improves wellbeing and overall quality of life of PLWHIV. In Malawi, there is paucity of information regarding PA levels among Malawians living with HIV and receiving ART. Therefore, this study aimed at determining PA levels among PLWHIV and receiving ART in Malawi.

Methods

A quantitative cross-sectional design was employed. Eligible participants were male and female adults aged 18–45 years living with HIV receiving ART for at least 1 year. The participants were recruited from Limbe Health Center, Gateway Health Center and Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi. The International Physical Activity Questionnaire (IPAQ) was used to assess the PA levels. A Stadiometer (HS-DBS00361, Model: 1127154) was used to measure weight (kg) and height (cm) of the participants.

Results

A total of 213 participants were recruited. There were more females than male participants (n=132 females). Overall, the mean age of all participants was 37±6.5 years and they were within normal body weight (BMI=23±4.0). Many participants (n=85, 40%) had low PA levels followed by those who were moderately physically active (n=75, 36%). A larger proportion of the female participants (51%) had low PA levels compared to males (22%). Forty-two percent of participants with 1–3 years of ART had low PA whereas 39% with >3 years ART had low PA.

Conclusion

Most PLWHIV and receiving ART in the sample have low PA levels. The study has also revealed that proportionally more females than males had low PA levels.

Effect of a Short-term Lifestyle Modification Program on Quality of Life, Anthropometric Characteristics and CD4+T Cell Count of HIV Infected Patients in Tehran/Iran: A Randomized Controlled Trial

CONTEXT

Increasing physical activity and promoting healthy behaviors may play a key role in reducing the adverse effects of antiretroviral therapy and HIV.

OBJECTIVE

This study investigated the effects of an 8-week lifestyle modification program (LMP) on quality of life, anthropometric characteristics and CD4+T cell count of people living with HIV (PLWH).

METHODS

Thirty PLWH taking ART were randomly assigned to a lifestyle modification program (LMP) (n = 15) or standard care control (CON) group (n = 15). All volunteers underwent body composition, CD4+T cell count measurement and quality of life assessments at the beginning and end of a two-month experimental period.

RESULTS

At follow-up, we observed a significant increase in CD4+T cell count (117.52 cells/mm³; 95% CI, 36.59-198.45) and all subscales and total quality of life score (Short-Form 36 (SF-36) in the LMP group. While we did not observe a significant change in body composition for the LMP group, we did observe a significant increase in body fat (1.75%; 95% CI, 0.15, 2.33) and a reduction in lean body mass (-1.26; 95% CI, -1.26, -2.39) for the CON group.

CONCLUSION

A LMP can be safely used as an effective intervention for improving quality of life and immune competence of PLWH who lack time to participate in a structured exercise regimen.

Lipodystrophic syndrome of HIV and associated factors: a study in a university hospital

The use of antiretroviral drugs has increased the survival of HIV patients, but may have side effects, such as lipodystrophic syndrome. This article aims to identify the frequency of the lipodystrophic syndrome and its associated factors in patients with HIV using antiretroviral therapy. It involved a cross-sectional study with HIV patients, monitored on an outpatient basis. The syndrome was evaluated by the association of two parameters: peripheral weight loss through the lipodystrophy severity scale and central fat accumulation, measured by the hip waist ratio. Poisson regression analysis was performed to identify the associated variables. Of the 104 patients evaluated, 27.9% presented the syndrome. After adjustment, the female sex (PRadjusted = 2.16 CI95% 1.43-3.39), being overweight (PRadjusted = 2.23 CI95% 1.35-2.65) and a longer period of use of antiretrovirals (PRadjusted = 1.64 CI95% 1.16-2.78), remained positively associated with the syndrome. On the other hand, a negative association with CD4 count £ 350 (PRadjusted = 0.39 CI95% 0.10-0.97) was observed The high prevalence of the syndrome and its association with specific groups reinforce the need for adequate follow-up and early identification to intervene in modifiable factors.

Physical activity among HIV-positive patients receiving antiretroviral therapy in Hanoi and Nam Dinh, Vietnam: a cross-sectional study

OBJECTIVES

Antiretroviral therapy (ART) has facilitated the transition of HIV infection into a chronic disease, where adherence to medications is required along with keeping a healthy lifestyle. Therefore, an increase in physical activity has been recommended for patients with HIV in order to maintain their health status. This study looked to determine the physical activity level and its associated factors among patients with HIV receiving ART treatment.

SETTINGS

Eight outpatient clinic sites across different levels of the health systems in both rural and urban settings in Hanoi and Nam Dinh, Vietnam.

STUDY DESIGN AND PARTICIPANTS

A cross-sectional study was performed among 1133 patients with HIV receiving ART treatment from January to August 2013.

PRIMARY AND SECONDARY OUTCOME MEASURES

Physical activity level was measured using the International Physical Activity Questionnaire (IPAQ). Socioeconomic, health-related quality of life, ART adherence and ART-related characteristics were self-reported.

RESULTS

16% of participants were inactive, and 68% were reported active via health-enhancing physical activity. Rural participants reported a higher level of physical activity compared with urban participants. Participants having a longer duration of ART were less likely to be physically active. Participants who were female and self-employed, who had higher CD4 cell count, higherEuroQol - 5 dimensions - 5levels (EQ-5D-5L) index/EQ-Visual Analogue Scale, and shared their health status with their peers were more likely to have a higher IPAQ score or be physically active. A lower IPAQ score was associated with participants living in urban areas and being at the symptomatic stage. Participants having poor adherence and longer duration of ART were more likely to be physically inactive.

CONCLUSION

The majority of participants who received ART were physically active. There is a need for interventions to promote physical activity among patients with HIV in urban areas and in the later ART treatment phases. Other potential interventions to increase the level of physical activity include peer support and job guidance.

Association of physical inactivity with hypertension and low educational level in people living with HIV / AIDS

The aim of this study was to determine the prevalence of physical inactivity and whether it is associated with sociodemographic, lifestyle, clinical, anthropometric, and body composition variables in people living with HIV/AIDS (PLWHA). This study makes use of data from a cohort of 288 adults aged ≥19 years, conducted between October 2009 and July 2011. The variables studied were sex, age, education, income, skin color, tobacco use, alcohol intake, body mass index, body fat percentage, waist circumference, and waist-hip ratio, length of HIV/AIDS diagnosis, use of antiretroviral therapy and length of its use, CD4, hypertension (HT) and diabetes mellitus. Physical inactivity was defined as a score below 600 metabolic equivalent minutes/week according to the International Physical Activity Questionnaire - Short Version. Poisson multiple regression was applied in the multivariate analysis with a significance level of 5%. The prevalence of physical inactivity was 44.1%. Education of ≤4 years of study (prevalence ratio [PR]: 1.71) and HT (PR: 1.49) were associated with physical inactivity. Physical inactivity was highly prevalent in PLWHA and associated with low educational level and HT. We highlight the simultaneous association between two cardiometabolic risk factors, HT and physical inactivity.

Associations Between At-Risk Alcohol Use, Substance Use, and Smoking with Lipohypertrophy and Lipoatrophy Among Patients Living with HIV

OBJECTIVE

To examine associations between lipohypertrophy and lipoatrophy and illicit drug use, smoking, and at-risk alcohol use among a large diverse cohort of persons living with HIV (PLWH) in clinical care.

METHODS

7,931 PLWH at six sites across the United States completed 21,279 clinical assessments, including lipohypertrophy and lipoatrophy, drug/alcohol use, physical activity level, and smoking. Lipohypertrophy and lipoatrophy were measured using the FRAM body morphology instrument and associations were assessed with generalized estimating equations.

RESULTS

Lipohypertrophy (33% mild, 4% moderate-to-severe) and lipoatrophy (20% mild, 3% moderate-to-severe) were common. Older age, male sex, and higher current CD4 count were associated with more severe lipohypertrophy (p values <.001-.03). Prior methamphetamine or marijuana use, and prior and current cocaine use, were associated with more severe lipohypertrophy (p values <.001-.009). Older age, detectable viral load, and low current CD4 cell counts were associated with more severe lipoatrophy (p values <.001-.003). In addition, current smoking and marijuana and opiate use were associated with more severe lipoatrophy (p values <.001-.03). Patients with very low physical activity levels had more severe lipohypertrophy and also more severe lipoatrophy than those with all other activity levels (p values <.001). For example, the lipohypertrophy score of those reporting high levels of physical activity was on average 1.6 points lower than those reporting very low levels of physical activity (-1.6, 95% CI: -1.8 to -1.4, p < .001).

CONCLUSIONS

We found a high prevalence of lipohypertrophy and lipoatrophy among a nationally distributed cohort of PLWH. While low levels of physical activity were associated with both lipohypertrophy and lipoatrophy, associations with substance use and other clinical characteristics differed between lipohypertrophy and lipoatrophy. These results support the conclusion that lipohypertrophy and lipoatrophy are distinct, and highlight differential associations with specific illicit drug use.

Physical activity correlates in people living with HIV/AIDS: a systematic review of 45 studies

PURPOSE

Understanding barriers and facilitators of physical activity participation in persons living with HIV/AIDS is an essential first step in order to devise effective interventions. The present review provides a systematic quantitative review of the physical activity correlates in people with HIV/AIDS.

METHODS

Major electronic databases were searched till August 2016. Keywords included "physical activity" or "exercise" or "sports" and "AIDS" or "HIV".

RESULTS

Out of 55 correlates from 45 studies (N = 13,167; mean age range = 30.5-58.3 years; 63.2% male) five consistent (i.e., reported in four or more studies) correlates were identified. Lower levels of physical activity were consistently associated with older age (6/10 studies), a lower educational level (6/7), a lower number of CD4 cells/μl (7/11), exposure to antiviral therapy (4/6), and the presence of lipodystrophy (4/4). Other important barriers were the presence of bodily pain (2/2), depression (3/3), and opportunistic infections (3/4). Facilitators were a higher cardiorespiratory fitness level (3/3), a higher self-efficacy (2/2), more perceived benefits (2/2), and a better health motivation (3/3).

CONCLUSIONS

The current review has elucidated that participation in physical activity by people with HIV/AIDS is associated with a range of complex factors which should be considered in rehabilitation programs. Implications for Rehabilitation Health care professionals should consider HIV-related bodily pain and feelings of depression when assisting people living with HIV in inititiating and maintaining an active lifestyle. Interventions to improve self-efficacy and motivation, and to help people living with HIV in understanding the benefits of exercise, may encourage greater participation.

Global physical activity levels among people living with HIV: a systematic review and meta-analysis

PURPOSE

It is unclear how much physical activity people living with HIV (PLWH) engage in. We conducted a meta-analysis to investigate physical activity levels and its predictors in PLWH.

METHODS

PubMed, PsycARTICLES, and CINAHL Plus were searched by two independent reviewers from inception till 1 April 2016 using the keywords: "HIV" OR "AIDS" AND "physical activity" OR "exercise" OR "sports". A random effects meta-analysis was conducted.

RESULTS

Across 24 studies including 34 physical activity levels there were 3780 (2471♂) PLWH (mean age range: 37-58 years). PLWH spent 98.9 (95%CI = 64.8-133.1) minutes per day being physically active which is lower than in most other populations with chronic diseases. 50.7% (95%CI = 39.3-62%) (n = 2052) of PLWH complied with the physical activity guidelines of 150 min moderate intensity physical activity per week. The number of steps walked per day in 252 PLWH was 5899 (95%CI = 5678-6418), which is below the 10,000 steps per day recommendation.

CONCLUSIONS

Our data demonstrate that a considerable proportion of PLWH are insufficiently physically active. Future lifestyle interventions specifically targeting the prevention of physical inactivity in PLWH are warranted. Implications for Rehabilitation Many people living with HIV do not comply with general health recommendations. Physical activity counseling should be key in the rehabilitation of people living with HIV.

Weight status and associated factors among HIV infected people on antiretroviral therapy in rural Dikgale, Limpopo, South Africa

BACKGROUND

Underweight in human immunodeficiency virus (HIV)-infected people on antiretroviral therapy (ART) complicates the management of HIV infection and contributes to mortality, whereas overweight increases the risk of cardiovascular disease (CVD).

AIM

The study determined weight status and associated factors in people with HIV infection receiving ART.

SETTING

Rural primary health care clinics in Dikgale, Limpopo province, South Africa.

METHODS

A cross-sectional study in which data were collected using the World Health Organization (WHO) stepwise approach to surveillance (STEPS) questionnaire and calculated using WHO analysis programmes guide. Weight and height were measured using standard WHO procedures, and body mass index was calculated as weight (kg)/height (m2). Data on ART duration were extracted from patients' files. CD4 lymphocyte counts and viral load were determined using standard laboratory techniques.

RESULTS

Of the 214 participants, 8.9%, 54.7% and 36.4% were underweight, normal weight and overweight, respectively. Physical activity (OR: 0.99, p = 0.001) and male gender (OR: 0.29, p = 0.04) were negatively associated with overweight. Men who used tobacco were more likely to be underweight than non-tobacco users (OR: 10.87, p = 0.02). Neither ART duration nor viral load or CD4 count was independently associated with underweight or overweight in multivariate analysis.

CONCLUSION

A high proportion of people on ART were overweight and a smaller proportion underweight. There is a need to simultaneously address the two extreme weight problems in this vulnerable population through educating them on benefits of avoiding tobacco, engaging in physical activity and raising awareness of CVD risk.

NÍVEL DE ATIVIDADE FÍSICA E SÍNDROME LIPODISTRÓFICA EM PACIENTES COM HIV/AIDS

Introdução: A atividade física pode ser uma aliada para minimizar o surgimento da lipodistrofia e seus efeitos deletérios. Objetivo: Analisar a relação do nível de atividade física (NAF) e a síndrome lipodistrófica com a composição corporal e a qualidade de vida (QV) de portadores do HIV/Aids. Métodos: Participaram do estudo 120 pacientes com HIV/Aids (38,55 ± 11,47 anos). Foram avaliados quanto ao índice de massa corporal, composição corporal, taxa metabólica basal, índice cintura-quadril, QV, presença, tipo e local de lipodistrofia, força de preensão manual e NAF. Resultados: Constatou-se que 70% eram sedentários; além disso, a massa magra foi 9,5% maior nos pacientes ativos, bem como a força muscular de preensão com a mão direita (11%) e esquerda (12%) e a taxa metabólica basal (6,9%). Quanto à associação da QV ao NAF, foi notada correlação fraca apenas para a preocupação com o sigilo (r = 0,2160; p = 0,0210), bem como, os pacientes ativos demonstraram melhor resultado que os sedentários (p < 0,05). Dos pacientes que apresentaram lipodistrofia, 66% eram sedentários; o tipo predominante foi a lipodistrofia mista (46%) e as regiões mais comuns foram a face e abdome. Ressalta-se que nos pacientes sem a síndrome a taxa metabólica basal foi maior (p = 0,0175) e o tempo de infecção (p = 0,0020) e de TARV (p = 0,0002) foram menores. Conclusão: Conclui-se, conforme metodologia adotada, que o sedentarismo predominou, o NAF apresentou associação positiva somente com a preocupação com o sigilo e os sedentários apresentaram dois domínios abaixo do escore de 50 (preocupação financeira e com o sigilo), com relação a um domínio dos pacientes ativos. A lipodistrofia esteve presente em 37% da amostra, sendo o tipo mais presente a lipodistrofia mista, e os locais de maior ocorrência foram a face e o abdome. Para esse grupo o NAF não se apresentou positivo para a composição corporal e a presença da lipodistrofia não influenciou na QV.

SL, Woods SP, Grant I, Jeste DV, Moore DJ. Physical Activity is Associated with Better Neurocognitive and Everyday Functioning Among Older Adults with HIV Disease

We examined the association between physical activity (PA), neurocognitive impairment (NCI), and instrumental activities of daily living (IADLs) among older HIV+ persons. One hundred older HIV+ adults completed the International Physical Activity Questionnaire, a neurocognitive battery, and IADL scale. Higher levels of moderate PA were associated with lower odds of NCI (p = 0.01), even when covariates were modeled. The association between moderate PA and NCI was driven by executive function (p = 0.04). Higher levels of moderate PA were also associated with lower odds of IADL Dependence (p = 0.03), although this fell to a trend (p = 0.08) when including covariates. Follow-up analysis showed those with both NCI and IADL Dependence had lower moderate PA than those with neither (p = 0.03). While these cross-sectional findings suggest PA is associated with better neurocognitive and everyday functioning in older HIV+ adults, longitudinal studies utilizing objective PA methods are needed to evaluate directionality and mechanisms.

[High prevalence of physical inactivity among adolescents living with HIV/Aids]

Objective:

To assess the prevalence of physical inactivity among adolescents with HIV/AIDS, as well as associated factors.

Methods:

Ninety-one adolescents (from 10 to 19 years old) with HIV/AIDS who are patients at a university follow-up service were interviewed. Anthropometric data (weight, height, and waist circumference) were measured twice; clinical information was obtained from medical records, and habitual physical activity was assessed by a questionnaire proposed by Florindo et al. The cutoff point for sedentariness was 300 minutes/week.

Results:

The prevalence of inadequate height for age, malnutrition, and overweight/obesity was 15.4%, 9.9% and 12.1%, respectively. The most common physical activities were soccer (44.4%), volleyball (14.4%) and cycling (7.8%). The median times spent with physical activity and walking/bicycling to school were 141 min and 39 min, respectively. Most adolescents (71.4%) were sedentary and this proportion was higher among girls (p=0.046).

Conclusions:

A high prevalence of physical inactivity among adolescents with HIV/AIDS was observed, similar to the general population. Promoting physical activity among adolescents, especially among girls with HIV/AIDS, as well as monitoring it should be part of the follow-up routine of these patients.

HIV/AIDS and lipodystrophy: implications for clinical management in resource-limited settings

Introduction

Lipodystrophy is a term used to describe a metabolic complication of fat loss, fat gain, or a combination of fat loss and gain, which is associated with some antiretroviral (ARV) therapies given to HIV-infected individuals. There is limited research on lipodystrophy in low- and middle-income countries, despite accounting for more than 95% of the burden of HIV/AIDS. The objective of this review was to evaluate the prevalence, pathogenesis and prognosis of HIV-related lipoatrophy, lipohypertrophy and mixed syndrome, to inform clinical management in resource-limited settings.

Methods

We conducted a structured literature search using MEDLINE electronic databases. Relevant MeSH terms were used to identify published human studies on HIV and lipoatrophy, lipohypertrophy, or mixed syndrome in low-, low-middle- and upper-middle-income countries through 31 March 2014. The search resulted in 5296 articles; after 1599 studies were excluded (958 reviews, 641 non-human), 3697 studies were extracted for further review. After excluding studies conducted in high-income settings (n=2808), and studies that did not meet inclusion criteria (n=799), 90 studies were included in this review.

Results and Discussion

Of the 90 studies included in this review, only six were from low-income countries and eight were from lower middle-income economies. These studies focused on lipodystrophy prevalence, risk factors and side effects of antiretroviral therapy (ART). In most studies, lipodystrophy developed after the first six months of therapy, particularly with the use of stavudine. Lipodystrophy is associated with increased risk of cardiometabolic complications. This is disconcerting and anticipated to increase, given the rapid scale-up of ART worldwide, the increasing number and lifespan of HIV-infected patients on long-term therapy, and the emergence of obesity and non-communicable diseases in settings with extensive HIV burden.

Conclusions

Lipodystrophy is common in resource-limited settings, and has considerable implications for risk of metabolic diseases, quality of life and adherence. Comprehensive evidence-based interventions are urgently needed to reduce the burden of HIV and lipodystrophy, and inform clinical management in resource-limited settings.

Kager's fat pad inflammation associated with HIV infection and AIDS: MRI findings

OBJECTIVE

To describe magnetic resonance imaging (MRI) features of Kager's fat pad inflammation in HIV-positive patients with lipodystrophy due to protease inhibitor treatment and posterior ankle pain.

METHODS

A case-control, cross-sectional study; group 1 included 14 HIV-positive patients using protease inhibitors, presenting lipodystrophy syndrome and having posterior ankle pain; group 2 (CGHIV-) included 112 HIV-negative patients without lipodystrophy syndrome who were being evaluated for posterior ankle pain; group 3 (CGHIV + 1) included 23 HIV-positive patients not using a protease inhibitor, without lipodystrophy syndrome and with posterior ankle pain; group 4 (CGHIV + 2) comprised 18 HIV-positive patients who were being treated with a protease inhibitor and had lipodystrophy syndrome but did not have posterior ankle pain. Images were evaluated for the presence of edema by two radiologists who were blinded to clinical features. Fisher's exact test was used to evaluate differences among the groups. Interobserver variation was tested using Cohen's kappa (κ) statistic.

RESULTS

The presence of edema within Kager's fat pad was strongly associated with symptoms in HIV-positive patients who had lipodystrophy (p ≤ 0.0001). Concordance between observers was excellent (κ > 0.9).

CONCLUSION

MRI findings of Kager's fat pad inflammation related to HIV/AIDS is a source of symptoms in HIV patients with posterior ankle pain using protease inhibitors and having lipodystrophy syndrome.

Malignancies in HIV/AIDS patients attending an outpatient clinic in Vitória, State of Espírito Santo, Brazil

INTRODUCTION

The present study investigated cancer prevalence and associated factors among HIV-infected individuals attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil.

METHODS

A sectional study was conducted among HIV infected adults attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. Demographic, epidemiological and clinical data were abstracted from medical records, including cancer diagnoses; nadir and current CD4 cell count, HIV viral load, time on antiretroviral treatment (ART), type of ART and smoking status.

RESULTS

A total of 730 (91.3%) patients were included in the study. Median age was 44.0 [interquartile range (IQR): 35-50.3] years; median time since HIV diagnosis was 5.5 years (IQR: 2-10); 60% were male; and 59% were white. Thirty (4.1%) cases of cancer were identified of which 16 (53%) were AIDS defining cancers and 14 (47%) were non-AIDS defining malignancies. Patients diagnosed with cancer presented higher chance of being tobacco users [OR 2.2 (95% CI: 1.04-6.24)]; having nadir CD4 ≤200 cells/mm³ [OR 3.0 (95% CI: 1.19-7.81)] and higher lethality [OR 13,3 (95% CI: 4,57-38,72)].

CONCLUSIONS

These results corroborate the importance of screening for and prevention of non-AIDS defining cancers focus in HIV-infected population, as these cancers presented with similar frequency as AIDS defining cancers.

Scleredema in a Patient with AIDS-Related Lipodystrophy Syndrome

Scleredema is a form of cutaneous mucinosis caused by an increased accumulation of collagen and mucin in the dermis. It is characterized by diffused, nonpitting swelling and induration of the skin. Scleredema diabeticorum is one type of scleredema associated with diabetes mellitus. AIDS-related insulin resistance and lipodystrophy syndrome are a newly emerging entities in HIV-infected patients associated with severe metabolic disturbances and insulin resistance. The long-standing diabetes in these patients may contribute to the development of scleredema diabeticorum. Here, we report the rare occurrence of scleredema in an HIV-infected patient with AIDS-related lipodystrophy syndrome.
