Abstract
OBJECTIVE To understand the prevalence of HIV-associated wasting (HIVAW) in the United States. DESIGN Medical and pharmacy claims study using IBM MarketScan Commercial, Medicare Supplemental and Medicaid Databases. METHODS Study period: July 2012-September 2018 (first HIV diagnosis claim = HIV index date). People with HIV (PWH) were excluded if they were aged less than 18 years, had any malignancy claim or had less than 6 months of enrollment data pre or post-HIV index date. HIVAW was defined by proxy using claims for weight loss-related diagnoses, appetite stimulant/nontestosterone anabolic agents or enteral/parenteral nutrition. Prevalence was reported cumulatively, by insurance type and antiretroviral therapy (ART) pharmacy claims (defined as ≥1 pharmacy claim of any ART within 12 months post-HIV index date). Statistical analysis assessed factors potentially associated with HIVAW. RESULTS The study population comprised 42 587 PWH (64.6% male, mean age 44 years, 67.5% on Medicaid, 63.9% on ART). Cumulative HIVAW prevalence (2012-2018) was 18.3% (n = 7804) for all PWH (17.9% on ART, 19.1% not on ART). HIVAW prevalence by payer was 7.5% for Commercial and Medicare Supplemental and 23.5% for Medicaid. The strongest associations with the likelihood of meeting the definition of HIVAW were for individuals with Medicaid and hospitalization(s) post-HIV index date; race and ART status were not associated. CONCLUSIONS Findings suggest HIVAW remains prevalent in PWH. ART use was not found to be associated with HIVAW. HIVAW was highest among those with Medicaid coverage or any hospitalization(s). Further research is needed to better understand additional factors associated with and contributing to HIVAW.

Abstract
PURPOSE OF REVIEW Sub-Saharan Africa (SSA) is disproportionately burdened by the twin epidemics of food insecurity and HIV infection, and protein-calorie undernutrition is common among persons with HIV (PWH) initiating antiretroviral therapy (ART) in the region. In this review, we discuss the intersection of HIV infection and undernutrition, health outcomes among undernourished PWH starting ART, and the demonstrated and potential benefits of therapeutic interventions such as micro/macronutrient supplementation and pharmacological agents. RECENT FINDINGS A low body mass index (BMI), used as a general indicator of poor nutrition in most studies, is associated with impaired immune recovery and increased mortality in the early ART period. The increased risk of mortality is multifactorial, and contributors include undernutrition-related immune system dysfunction, increased susceptibility to opportunistic infections, and metabolic and cardiovascular dysregulation. Clinical trials of micro/macronutrient supplementary feeding, appetite stimulants (hormones and anabolic agents), and recombinant adipokines have shown a benefit for weight gain and metabolic health, but there are few data on mortality or immune recovery. A substantial proportion of PWH in SSA are undernourished, and undernutrition contributes to an increased risk of mortality and other adverse health outcomes. To date, there have been few prospective trials of nutritional supplementation and/or pharmacologic therapy among undernourished PWH in SSA, though findings from other settings suggest a potential benefit in this population.

Abstract
Mood disorders are more frequent among people with HIV infection than among non-HIV-infected individuals of the same age, socioeconomic status, and HIV risks. They have been associated with worse adherence and clinical outcomes, yet remain underdiagnosed and undertreated in sub-Saharan Africa. We explored the relationship between mood disorders using the 10-item depression scale of the Centers for Epidemiological Studies (CES-D10) and the 22-item Impact of Events Scale-Revised (IES-R) for posttraumatic stress disorder, and a range of demographic and HIV-related variables among 252 consecutive subjects on antiretroviral therapy (ART). The study was conducted in the Genito-Urinary Medicine Clinic of the Medical Research Council's Gambia Unit. These screening tests were positive in 7% and 30%, respectively, of the patients, with higher scores (more depression or more post-traumatic stress) associated with female gender, more advanced WHO clinical stage, and lower Karnofsky Perfomance Scale rating. Higher CES-D10 scores were also seen among those on their second ART regimen. No relationship was seen with age, time on ART, viral load, or CD4 cell count. Compared to an earlier study at the same site in subjects prior to starting ART, the prevalence of depression in those stabilized on ART was dramatically reduced (by 34%, from 41%) while that of PTSD dropped less (by 13%, from 43%). Integrating the CES-D10 or a similar instrument into patient preparation for ART is recommended in order to identify those who may benefit from further mental health investigations, specific therapy, or closer follow-up during early ART.

Effect of probiotic bacteria on microbial host defense, growth, and immune function in human immunodeficiency virus type-1 infection. Nutrients 2011; 3:1042-70. [PMID: 22292110 PMCID: PMC3260491 DOI: 10.3390/nu3121042] [Citation(s) in RCA: 69] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2011] [Revised: 11/24/2011] [Accepted: 12/05/2011] [Indexed: 02/07/2023] Open
Abstract
The hypothesis that probiotic administration protects the gut surface and could delay progression of Human Immunodeficiency Virus type1 (HIV-1) infection to the Acquired Immunodeficiency Syndrome (AIDS) was proposed in 1995. Over the last five years, new studies have clarified the significance of HIV-1 infection of the gut associated lymphoid tissue (GALT) for subsequent alterations in the microflora and breakdown of the gut mucosal barrier leading to pathogenesis and development of AIDS. Current studies show that loss of gut CD4+ Th17 cells, which differentiate in response to normal microflora, occurs early in HIV-1 disease. Microbial translocation and suppression of the T regulatory (Treg) cell response is associated with chronic immune activation and inflammation. Combinations of probiotic bacteria which upregulate Treg activation have shown promise in suppressing pro inflammatory immune response in models of autoimmunity including inflammatory bowel disease and provide a rationale for use of probiotics in HIV-1/AIDS. Disturbance of the microbiota early in HIV-1 infection leads to greater dominance of potential pathogens, reducing levels of bifidobacteria and lactobacillus species and increasing mucosal inflammation. The interaction of chronic or recurrent infections, and immune activation contributes to nutritional deficiencies that have lasting consequences especially in the HIV-1 infected child. While effective anti-retroviral therapy (ART) has enhanced survival, wasting is still an independent predictor of survival and a major presenting symptom. Congenital exposure to HIV-1 is a risk factor for growth delay in both infected and non-infected infants. Nutritional intervention after 6 months of age appears to be largely ineffective. A meta analysis of randomized, controlled clinical trials of infant formulae supplemented with Bifidobacterium lactis showed that weight gain was significantly greater in infants who received B. lactis compared to formula alone. Pilot studies have shown that probiotic bacteria given as a supplement have improved growth and protected against loss of CD4+ T cells. The recognition that normal bacterial flora prime neonatal immune response and that abnormal flora have a profound impact on metabolism has generated insight into potential mechanisms of gut dysfunction in many settings including HIV-1 infection. As discussed here, current and emerging studies support the concept that probiotic bacteria can provide specific benefit in HIV-1 infection. Probiotic bacteria have proven active against bacterial vaginosis in HIV-1 positive women and have enhanced growth in infants with congenital HIV-1 infection. Probiotic bacteria may stabilize CD4+ T cell numbers in HIV-1 infected children and are likely to have protective effects against inflammation and chronic immune activation of the gastrointestinal immune system.

Abstract
This study aimed to assess the prevalence and clinical and psychosocial correlates of psychiatric symptoms in a sample of HIV patients in the Gambia. Data from 44 HIV-positive outpatients were collected at a Genito-Urinary Medicine clinic in Fajara, the Gambia. Translated versions of the Impact of Event Scale Revised and the Centre for Epidemiologic Studies Short Depression Scale were used to assess posttraumatic stress disorder (PTSD) symptoms and depressive symptoms, respectively. The Pictorial Representation of Illness and Self Measure revised was used to assess illness perception (IP). All other data (e.g., CD4 counts) were retrieved from medical charts or through standardised questions. The prevalence of PTSD symptoms (43.2%) and depressive symptoms (40.9%) was high. Not having an independent income and having a CD4 count under 200 cells/µl were independent correlates of depressive symptoms. Only IP was an independent correlate of PTSD symptoms. Finally, IP tended to moderate the relationship between CD4 cell counts and depressive symptoms. These findings indicate that routine screening for psychiatric symptoms is both necessary and feasible among HIV patients in the Gambia. In addition, any intervention targeting these symptoms should take IP into account.

Abstract
Studies described in the recent literature support the idea that gene therapy can lead to genuine clinical benefits when mediated by plasmid delivery in conjunction with electroporation. Plasmid-mediated muscle-targeted gene transfer offers the potential of a cost-effective pharmaceutical-grade therapy delivered by simple intramuscular injection. This approach is particularly appropriate for modulating muscle and fat mass and their intrinsic properties, from treatment of conditions such as cachexia associated with chronic diseases, autoimmune diseases, e.g., myasthenia gravis, to stimulation or suppression of appetite, and further to in vivo manipulation of glucose metabolism and fat deposition in patients with diabetes, or to basic studies of muscle-specific transcription factors and their impact in development. Recent innovations, including in situ electroporation, enabling sustained systemic protein delivery within the therapeutic range, are reviewed. Translation of these advances to human clinical trials will enable muscle- and fat-targeted gene therapy to become a viable therapeutic alternative.

Abstract
BACKGROUND According to current recommendations, HIV-infected women should have at least 1 gynecologic examination per year. OBJECTIVES To analyze factors associated with frequency of gynecologic follow-up and cervical cancer screening among HIV-infected women followed in the Swiss HIV Cohort Study (SHCS). METHODS Half-yearly questionnaires between April 2001 and December 2004. At every follow-up visit, the women were asked if they had had a gynecologic examination and a cervical smear since their last visit. Longitudinal models were fitted with these variables as outcomes. RESULTS A total of 2186 women were included in the analysis. Of the 1146 women with complete follow-up in the SHCS, 35.3% had a gynecologic examination in each time period, whereas 7.4% had never gone to a gynecologist. Factors associated with a poor gynecologic follow-up were older age, nonwhite ethnicity, less education, underweight, obesity, being sexually inactive, intravenous drug use, smoking, having a private infectious disease specialist as a care provider, HIV viral load <400 copies/mL, and no previous cervical dysplasia. No association was seen for living alone, CD4 cell count, and positive serology for syphilis. CONCLUSIONS Gynecologic care among well-followed HIV-positive women is poor and needs to be improved.

Abstract
This article reviews the clinical data on recombinant human growth hormone therapy of body composition abnormalities in HIV-infected patients. Short-term recombinant human growth hormone therapy at pharmacologic doses modestly increases total body weight and lean body mass in patients with HIV wasting, resulting in improvements in physical capacity and quality of life. Short-term recombinant human growth hormone therapy has a clear dose-dependent impact on trunk and visceral fat in HIV-infected patients with central fat accumulation, resulting in improvements in perception of body image and a beneficial effect on lipid parameters. Recombinant human growth hormone therapy is also accompanied by dose-dependent side effects related to fluid retention and increased insulin resistance. The optimal treatment strategy, maintenance dose and duration of treatment have not been identified.

Abstract
HIV-associated wasting, characterised by progressive loss of lean body mass and bodyweight, remains a significant problem in the era of highly active antiretroviral therapy (HAART). Loss of body cell mass, a component of lean body mass, is associated with decreased survival. Somatropin (recombinant human growth hormone) derived from mammalian cells (Serostim) is the only US FDA-approved treatment indicated to increase lean body mass, bodyweight and physical endurance in HIV-associated wasting. Somatropin 0.1 mg/kg/day administered subcutaneously for 12 weeks effectively increased work output, bodyweight and lean body mass and improved health-related quality of life (HR-QOL), compared with placebo, and had a generally manageable tolerability profile in a large randomised study in patients with HIV-associated wasting. Potential areas for further research include determination of longer-term efficacy and tolerability, the cost effectiveness of treatment, the optimal somatropin dosage, management of patients after 12 weeks' therapy and whether maintenance strategies might exist to maintain accrued lean body mass with lower doses of somatropin. Nevertheless, indications to date are that somatropin is likely to have an important role in the treatment of patients with HIV-associated wasting.

Abstract
Despite major advances in the treatment and survival of patients infected with human immunodeficiency virus (HIV), weight loss and wasting remain common problems. In the HIV-infected population, weight loss is associated with lower CD4+ cell counts and is an independent predictor of mortality. The etiology of weight loss and wasting is complex and multifactorial. We discuss, on the basis of a large longitudinal cohort that examined nutritional status in HIV infection, data on weight loss and wasting from the present clinical era. The definition, prevalence, and significance of HIV-associated weight loss and wasting are summarized. The etiology of weight loss is discussed for 2 main categories: inadequate nutrient intake and altered metabolism. Finally, studies of interventions to treat HIV-associated weight loss and wasting are discussed. This information is intended to raise awareness among health care providers of HIV-infected patients that weight loss and wasting remain important acquired immunodeficiency syndrome-defining conditions, despite the advent of HAART.
