RESUMO

Women living with HIV (WLWH) are at increased risk of anal cancer compared to women without HIV, often due to persistent human papillomavirus (HPV) infections. This paper describes current practices and challenges conducting anal cancer screening for WLWH at an urban integrated safety-net system and a non-profit community-based HIV clinic. We conducted 25 semi-structured interviews with clinical and administrative stakeholders to assess knowledge, clinic practices and procedures, and experiences with anal cancer screening. Interview transcripts and fieldnotes were thematically analyzed using an iterative deductive and inductive coding scheme. Findings were organized by the Consolidated Framework for Implementation Research (CFIR) domains and constructs. Provider-level barriers to conducting anal cancer screening included limited knowledge of guidelines. System-level barriers included: structural characteristics such as lack of coordination between clinics to discern provider roles and responsibilities; and limitations in available resources such as configuration of electronic health records and infrastructure to manage referrals of abnormal anal Pap results. We conclude that anal cancer screening and follow-up for WLWH requires organization and coordination between multiple care teams, updated clinical information systems to facilitate communication and support anal Pap ordering and result documentation, and infrastructure that includes policies and protocols for management of abnormal results.Trial registration: ClinicalTrials.gov identifier: NCT02135419.

RESUMO

Understanding the correlates of depression in HIV patients can help identify groups whose members are at increased risk for depression. We conducted a cross-sectional retrospective study among racially diverse, indigent patients living with HIV (PLWH) who were obtaining care in an urban safety-net hospital system and had completed a Patient Health Questionnaire-9 (PHQ-9) in 2014 or 2015. We collected demographics, HIV risk factors, HIV viral loads, CD4 counts, missed visits, and emergency department (ED) visits. Data from the Substance Abuse and Mental Illness Symptoms Screener (SAMISS) were abstracted. Missing data on substance use and CD4 cell counts were imputed to examine the odds of depression (PHQ-9 ≥ 10) by multivariable analysis for a complete case and sensitivity analysis. Stratified analysis by HIV viral suppression (VS) was used to determine the odds of depression among subgroups. Of the 5126 HIV patients (70.8% male,56.3% Black, 44.6% MSM, 6.0% IDU), 1271 (24.8%) experienced depression (PHQ ≥ 10). In a multivariable logistic model female gender, White race, injection drug use (IDU) or men who have sex with men (MSM) as an HIV risk factor, making ≥1 ED visit, having missed any HIV visit, having AIDS, and having a positive drug screen by SAMISS increased the odds for depression. Those who had achieved HIV VS or received efavirenz had lower odds of depression. Even among those with AIDS, those failing to achieve VS were at increased odds for depression, whereas those achieving VS were not. Moderate to severe depression is prevalent among PLWH. Among those with AIDS, HIV VS modifies the odds of depression.

RESUMO

OBJECTIVES: The aims of the study were (1) to describe anal cancer knowledge, perceived risk, screening barriers, and acceptability of sample self-collection among women living with HIV (WLWH) at an integrated safety-net system and (2) to describe differences in demographic and psychosocial variables among a subsample of WLWH with a history of abnormal cervical cytology results versus those with normal results. MATERIALS AND METHODS: We conducted telephone surveys with English- and Spanish-speaking WLWH (N = 99) and used electronic health record data to extract insurance type, CD4+ cell count, RNA viral load, and cervical cytology results. We calculated descriptive statistics for participant demographics, HIV laboratory results, and psychosocial variables. Among the subsample of women who completed a recent cervical Pap, we used Fisher exact test to assess differences in demographic variables, CD4+ counts, RNA viral loads, knowledge, awareness, acceptability, and perceived risk by cervical cytology results. RESULTS: Most participants (70%) reported knowing nothing about anal cancer; 28% correctly responded that HIV increases one's chance of getting anal cancer. Most (68%) never heard of an anal Pap test. Forty percent would get an anal Pap if they could self-collect the sample, whereas 59% were neutral or disagreed. The 2 most commonly cited barriers to obtaining an anal Pap were "I do not know enough about it" (n = 15) and "It might hurt" (n = 9). CONCLUSIONS: This study highlights a gap in knowledge and awareness among WLWH regarding their heightened risk for anal cancer. It indicates the need for health education and suggests an opportunity for a self-collection intervention.

RESUMO

Background: Fibrosis in lymph nodes may limit CD4+ T-cell recovery, and lymph node and adipose tissue fibrosis may contribute to inflammation and comorbidities despite antiretroviral therapy (ART). We hypothesized that the angiotensin receptor blocker and peroxisome proliferator-activated receptor γ agonist telmisartan would decrease lymph node or adipose tissue fibrosis in treated human immunodeficiency virus type 1 (HIV) infection. Methods: In this 48-week, randomized, controlled trial, adults continued HIV-suppressive ART and received telmisartan or no drug. Collagen I, fibronectin, and phosphorylated SMAD3 (pSMAD3) deposition in lymph nodes, as well as collagen I, collagen VI, and fibronectin deposition in adipose tissue, were quantified by immunohistochemical analysis at weeks 0 and 48. Two-sided rank sum and signed rank tests compared changes over 48 weeks. Results: Forty-four participants enrolled; 35 had paired adipose tissue specimens, and 29 had paired lymph node specimens. The median change overall in the percentage of the area throughout which collagen I was deposited was -2.6 percentage points (P = 0.08) in lymph node specimens and -1.3 percentage points (P = .001) in adipose tissue specimens, with no between-arm differences. In lymph node specimens, pSMAD3 deposition changed by -0.5 percentage points overall (P = .04), with no between-arm differences. Telmisartan attenuated increases in fibronectin deposition (P = .06). In adipose tissue, changes in collagen VI deposition (-1.0 percentage point; P = .001) and fibronectin deposition (-2.4 percentage points; P < .001) were observed, with no between-arm differences. Conclusions: In adults with treated HIV infection, lymph node and adipose tissue fibrosis decreased with continued ART alone, with no additional fibrosis reduction with telmisartan therapy.

RESUMO

Objective. To compare HIV drug resistance in pregnant women with perinatal HIV (PHIV) and those with nonperinatal HIV (NPHIV) infection. Methods. We conducted a multisite cohort study of PHIV and NPHIV women from 2000 to 2014. Sample size was calculated to identify a fourfold increase in antiretroviral (ARV) drug resistance in PHIV women. Continuous variables were compared using Student's t-test and Wilcoxon rank-sum tests. Categorical variables were compared using χ (2) and Fisher's exact tests. Univariate analysis was used to determine factors associated with antiretroviral drug resistance. Results. Forty-one PHIV and 41 NPHIV participants were included. Women with PHIV were more likely to have drug resistance than those with NPHIV ((55% versus 17%, p = 0.03), OR 6.0 (95% CI 1.0-34.8), p = 0.05), including multiclass resistance (15% versus 0, p = 0.03), and they were more likely to receive nonstandard ARVs during pregnancy (27% versus 5%, p = 0.01). PHIV and NPHIV women had similar rates of preterm birth (11% versus 28%, p = 0.08) and cesarean delivery (47% versus 46%, p = 0.9). Two infants born to a single NPHIV woman acquired HIV infection. Conclusions. PHIV women have a high frequency of HIV drug resistance mutations, leading to nonstandard ARVs use during pregnancy. Despite nonstandard ARV use during pregnancy, PHIV women did not experience increased rates of adverse pregnancy outcomes.

RESUMO

The New York State HIV-HCV-STD Clinical Education Initiative (CEI) has developed a large repository of online resources and disseminated them to a wide range of healthcare providers. To evaluate the CEI online education program and in particular to compare the self-reported measures by clinicians from different disciplines, we analyzed the data from 1,558 course completions in a study period of three months. The results have shown that the overall evaluations by the clinicians were very positive. Meanwhile, there were significant differences across the clinical disciplines. In particular, physicians and nurse practitioners were the most satisfied. In contrast, pharmacists and case/care managers recorded lower than average responses. Nurses and counselors had mixed results. Nurse practitioners' responses were very similar to physicians on most measures, but significantly different from nurses in many aspects. For more effective knowledge dissemination, online education programs should consider the unique needs by clinicians from specific disciplines.

RESUMO

OBJECTIVE: HIV-infected older adults (HOA) are at risk of functional decline. Interventions promoting physical activity that can attenuate functional decline and are easily translated into the HOA community are of high priority. We conducted a randomized, controlled clinical trial to evaluate whether a physical activity counseling intervention based on self-determination theory (SDT) improves physical function, autonomous motivation, depression and the quality of life (QOL) in HOA. METHOD: In total, 67 community-dwelling HOA with mild-to-moderate functional limitations were randomized to 1 of 2 groups: a physical activity counseling group or the usual care control group. We used SDT to guide the development of the experimental intervention. Outcome measures that were collected at baseline and final study visits included a battery of physical function tests, levels of physical activity, autonomous motivation, depression, and QOL. RESULTS: The study participants were similar in their demographic and clinical characteristics in both the treatment and control groups. Overall physical performance, gait speed, measures of endurance and strength, and levels of physical activity improved in the treatment group compared to the control group (p < .05). Measures of autonomous regulation such as identified regulation, and measures of depression and QOL improved significantly in the treatment group compared with the control group (p < .05). Across the groups, improvement in intrinsic regulation and QOL correlated with an improvement in physical function (p < .05). CONCLUSION: Our findings suggest that a physical activity counseling program grounded in SDT can improve physical function, autonomous motivation, depression, and QOL in HOA with functional limitations.

RESUMO

BACKGROUND: The use of combination antiretroviral therapy (cART) has significantly decreased the morbidity and mortality associated with human immunodeficiency virus (HIV) infection. Lipid disorders, including lipodystrophy, hypertriglyceridemia, and hypercholesterolemia, remain the most commonly reported metabolic disorders among those treated with long-term cART. Mounting evidence suggests an association between drug abuse and poor glycemic control and diabetes complications. Substance related disorders (SRD) may increase the risk of metabolic syndrome. MATERIALS AND METHODS: The aim of this retrospective cohort study was to examine the relationship between SRD, cART, and lipid-lowering agent use in an HIV infected population. Patients received efavirenz or protease inhibitor-based cART for at least 6 months. Prescription information was retrieved from the medical records. The primary outcome was the use of lipid-lowering agents including statins, fibrates and fish oil. The impact of SRD and cART was assessed on the lipid-lowering agent use. RESULTS: A total of 276 subjects with HIV infection were included, 90 (33%) received lipid-lowering agents, and 31 (34%) had SRD. Smoking was prevalent among subjects with SRD (84 vs 15%, p<0.001). Statins were the mainstay for the management of dyslipidemia (66%), followed by the fibrates (24%), omega-3 fatty acids (5%), nicotinic acid (3%) and the cholesterol absorption inhibitors (3%). Use of statins or fibrates was significantly higher among subjects without SRD than those with (40 vs 23%, p=0.005). The type of cART, including efavirenz and protease inhibitors, appeared to have no significant impact on the use pattern of lipid-lowering agents. Lopinavir/ritonavir (lopinavir/r) was mostly prescribed for subjects with SRD (25 vs 8%, p=0.02). CONCLUSION: Among HIV-infected patients, statins remain the mainstay for the management of dyslipidemia in routine clinical care, followed by fibrates. A significant high risk of metabolic disorders among patients with SRD is implicated by heavy tobacco use and prevalent lopinavir/r-based treatment. Significantly low rate of lipid-lowering agent use in this population underscores the importance of lipid disorder scrutiny and cART treatment optimization for HIV-infected patients with SRD.

RESUMO

OBJECTIVES: Depot medroxyprogesterone acetate (DMPA) was associated with increased HIV transmission and accelerated disease progression in untreated women. The potential underlying mechanisms include immune modulation. We evaluated the effect of a single DMPA injection on cell-mediated immunity (CMI), T-cell activation, T-cell regulation (Treg), and inflammation in HIV-infected women on combination antiretroviral regimen (cART). METHODS: Women with HIV plasma RNA ≤ 400 copies per milliliter on stable cART received DMPA and had immunologic and medroxyprogesterone acetate (MPA) measurements at baseline, 4 weeks [peak MPA concentration (Cmax)], and 12 weeks [highest MPA area under the concentration curve]. RESULTS: At baseline, among 24 women with median age of 32 years and 622 CD4(+) cells per microliter, ≥ 68% had HIV, varicella-zoster virus, phytohemagglutinin A and CD3/CD28 CMI measured by lymphocyte proliferation, and/or IFNγ/IL2 dual-color fluorospot. CMI did not significantly change after DMPA administration except for a 1.4-fold increase in IL2/IFNγ varicella-zoster virus fluorospot at week 12. T-cell activation decreased after DMPA administration, reaching statistical significance at week 12 for CD4(+)CD25+%. Treg behaved heterogeneously with an increase in CD8+FOXP3+% at week 4 and a decrease in CD4+IL35+% at week 12. There was a decrease in TGFß at week 12 and no other changes in plasma biomarkers. Correlation analyses showed that high MPA Cmax and/or area under the concentration curve were significantly associated with increases of IFNγ HIV enzyme-linked ImmunoSpot, CD4+IL35+%, and CD4+TGFß+% Treg and decreases of plasma IL10 from baseline to weeks 4 and/or 12. CONCLUSIONS: A single dose of DMPA did not have immune-suppressive or pro-inflammatory effects in HIV-infected women on cART. Additional studies need to assess the effect of multiple doses.

RESUMO

Dissemination of the latest clinical evidence to community-based healthcare providers is a critical step to translate biomedical knowledge into clinical practice. We performed a study to analyze the correlations between the promotional activities and the usage of a guideline-driven interactive case simulation tool (ICST) for insomnia screening and treatment in a statewide HIV-HCV-STD clinical education program. For this purpose, we tracked users' interactions with the ICST and the sending of promotional email newsletters during a study period of 44 weeks. Results showed that promotional activities were strongly correlated with the number of audience as well as the intensity of use of the target resource. The strength of correlation varied in specific use contexts. Strong correlations were found between the sending of email newsletters and the intensity of resource use by promotion recipients, by new users, and through the most convenient access channel associated with the promotion. Selection of approaches for resource dissemination should consider the potentials and limitations of use contexts to make them more effective.

RESUMO

We conducted an open-label, steady-state pharmacokinetic (PK) study of drug-drug interactions between depot medroxyprogesterone acetate (DMPA) and twice-daily lopinavir (LPV) plus low-dose ritonavir (RTV) (LPV/r) among 24 HIV-infected women and compared the results to those for HIV-infected women receiving DMPA while on no antiretroviral therapy or on nucleosides only (n = 14 subjects from the control arm of AIDS Clinical Trials Group [ACTG] study 5093). The objectives of the study were to address the effect of LPV/r on DMPA and to address the effect of DMPA on LPV/r therapy. PK parameters were estimated using noncompartmental analysis with between-group comparisons of medroxyprogesterone acetate (MPA) PKs and within-subject comparisons of LPV and RTV PKs before and 4 weeks after DMPA dosing. Plasma progesterone concentrations were measured every 2 weeks after DMPA dosing through week 12. Although the MPA area under the concentration-time curve and maximum concentration of drug in plasma were statistically significantly increased in the study women on LPV/r compared to those in the historical controls, these increases were not considered clinically significant. There were no changes in LPV or RTV exposure after DMPA. DMPA was well tolerated, and suppression of ovulation was maintained. (This study has been registered at ClinicalTrials.gov under registration no. NCT01296152.).

RESUMO

OBJECTIVES: During the earlier years of the HIV/AIDS epidemic, initial reports described sensorineural hearing loss in up to 49% of individuals with HIV/AIDS. During those years, patients commonly progressed to advanced stages of HIV disease and frequently had neurological complications. However, the abnormalities on pure-tone audiometry and brainstem-evoked responses outlined in small studies were not always consistently correlated with advanced stages of HIV/AIDS. Moreover, these studies could not exclude the confounding effect of concurrent opportunistic infections and syphilis. Additional reports also have indicated that some antiretroviral medications may be ototoxic; thus, it has been difficult to make conclusions regarding the cause of changes in hearing function in HIV-infected patients. More recently, accelerated aging has been suggested as a potential explanation for the disproportionate increase in complications of aging described in many HIV-infected patients; hence, accelerated aging-associated hearing loss may also be playing a role in these patients. DESIGN: We conducted a large cross-sectional analysis of hearing function in over 300 patients with HIV-1 infection and in 137 HIV-uninfected controls. HIV-infected participants and HIV-uninfected controls underwent a 2-hr battery of hearing tests including the Hearing Handicap Inventory, standard audiometric pure-tone air and bone conduction testing, tympanometric testing, and speech reception and discrimination testing. RESULTS: Three-way analysis of variance (ANOVA) and logistic regression analysis of 278 eligible HIV-infected subjects stratified by disease stage in early HIV disease (n = 127) and late HIV disease (n = 148) and 120 eligible HIV-uninfected controls revealed no statistically significant differences among the three study groups in either overall 4-frequency pure-tone average (4-PTA) or hearing loss prevalence in either ear. Three-way ANOVA showed significant differences in word recognition scores in the right ear among groups, a significant group effect on tympanogram static admittance in both ears and a significant group effect on tympanic gradient in the right ear. There was significantly larger admittance and gradient in controls as compared to the HIV-infected group at late stage of disease. Hearing loss in the HIV-infected groups was associated with increased age and was similar to that described in the literature for the general population. Three-way ANOVA analysis also indicated significantly greater pure-tone thresholds (worse hearing) at low frequencies in HIV patients in the late stage of disease compared with HIV-uninfected controls. This difference was also found by semi-parametric mixed effects models. CONCLUSIONS: Despite reports of "premature" or "accelerated" aging in HIV-infected subjects, we found no evidence of hearing loss occurring at an earlier age in HIV-infected patients compared to HIV-uninfected controls. Similar to what is described in the general population, the probability of hearing loss increased with age in the HIV-infected subjects and was more common in patients over 60 years of age. Interestingly, HIV-infected subjects had worse hearing at lower frequencies and have significant differences in tympanometry compared to HIV-uninfected controls; these findings deserve further study.

RESUMO

The HIV-infected older adult (HOA) community is particularly vulnerable to cognitive impairment. Previous studies in the general older adult population have reported that lower scores on tests of cognitive function often correlate negatively with aerobic fitness [5-7]. HIV-infected individuals have significantly reduced aerobic fitness and physical function compared to HIV-uninfected individuals. Determining important correlates of cognitive ability may be beneficial in not only detecting precursors to future cognitive impairments, but also target areas for interventions. The purpose of this study was to investigate the relationship between cognitive ability and aerobic fitness in HIV-infected older adults. We conducted a cross-sectional study of HOA on antiretroviral therapy (ART) >50 years of age. Domain specific cognitive function was assessed by means of a neuropsychological battery. Aerobic fitness (VO2peak) was assessed using a graded, progressive treadmill test. Thirty-seven HOA on ART (mean±SD: age 59±6 years, BMI 28±5, CD4 663±337 cells/ml, duration since HIV diagnosis 17±7 years; 81% males) completed the cognitive tests. Several domains of cognition were significantly associated with VO2peak by Spearman correlation analysis (p<0.05). By step-wise adjusted regression VO2peak was most frequently and significantly related to many cognitive domains such as verbal and visual memory, visual perception, and language (p<0.05). We found that participants with higher Vo2peak were less likely to have more severe forms of HIV-associated neurocognitive disorders (HAND) such as mild neurocognitive disorder (OR=0.65; p=0.01) and HIV-associated dementia (OR=0.64; p=0.0006). In HOA and in conclusion, aerobic fitness is related to cognitive performance on various tasks. The likelihood of cognitive impairment increased with lower fitness levels. Therefore, increased fitness may serve an important factor in maintenance of cognition and neural integrity for aging HIV-infected individuals. Future prospective and large scale studies are needed to evaluate the effect of fitness and vascular stiffness and function on cognition and brain structure among HOA.

RESUMO

OBJECTIVE: To assess whether CD8 T-cell activation predicts risk of AIDS and non-AIDS morbidity during suppressive antiretroviral treatment (ART). DESIGN: Post-hoc analyses of ART-naive participants in prospective ART studies. Participants with HIV-RNA levels 200 copies/ml or less and CD8 T-cell activation data (%CD38HLA-DR) at year-1 of ART were selected to determine years 2-5 incidence of AIDS and non-AIDS events. METHODS: We censored data at time of ART interruption or virologic failure. Inverse probability of censoring-weighted logistic regression was used to correct for informative censoring. RESULTS: We included 1025 participants; 82% were men, median age 38 years, pre-ART CD4 cell count 255 cells/µl, and year-1-activated CD8 T cells 24%. Of these, 752 had 5 years of follow-up; 379 remained on ART and had no confirmed plasma HIV-RNA more than 200 copies/ml. The overall probability of an AIDS or non-AIDS event in years 2-5 was estimated at 13% [95% confidence interval (CI) 10-15%] had everyone remained on suppressive ART. Higher year-1-activated CD8 T-cell percentage increased the probability of subsequent events [odds ratio 1.22 per 10% higher (95% CI 1.04-1.44)]; this effect was not significant after adjusting for age. Among those age 50 years at least (n=108 at year 1), the probability of an event in years 2-5 was 37% and the effect of CD8 T-cell activation was more apparent (odds ratio=1.42, P=0.02 unadjusted and adjusted for age). CONCLUSION: CD8 T-cell activation is prognostic of clinical events during suppressive ART, although this association is confounded by age. The consequences of HIV-associated immune activation may be more important in patients 50 years and older.

RESUMO

Interactive case simulation tools (ICSTs) are important vehicles to disseminate medical knowledge. We conducted a study to examine the usage of an insomnia screening and treatment case simulation tool in an HIV clinical education program. Using system usage diagrams (SUDs) as an instrument, we quantified visit frequency and length of stay for different types of system resources. Preliminary results have shown that both recommendations and interactive decision diagrams were frequently used, with the former having a longer length of stay but fewer visits. Case simulation functions seemed to be able to engage users. Future research is required to verify the generalizability of the identified usage patterns, to investigate issues in usability design, and to perform correlation analyses on system usage and context parameters.

RESUMO

The prevalence of human immunodeficiency virus (HIV) infection among people older than 50 years is increasing. Older HIV-infected patients are particularly at risk for polypharmacy because they often have multiple comorbidities that require pharmacotherapy. Overall, there is not much known with respect to both the impact of aging on medication use in HIV-infected individuals, and the potential for interactions with highly active antiretroviral therapy (HAART) and coadministered medications and its clinical consequences. In this review, we aim to provide an overview of polypharmacy with a focus on its impact on the HIV-infected older adult population and to also provide some clinical considerations in this high-risk population.

RESUMO

BACKGROUND: Federal meaningful use standards are promoting adoption of online portals to personal health records (PHRs). However, relatively little is known regarding barriers and facilitators for vulnerable groups such as persons living with human immunodeficiency virus (PLWH). OBJECTIVE: The objective of this study was to assess barriers and facilitators to use of online PHRs among PLWH. METHODS: We conducted formative research using a written waiting room survey among 120 PLWH regarding barriers and facilitators of portal PHR use. We supplemented findings with data collected from a PLWH focus group, where some members had personal experience with use of a portal. RESULTS: The survey had 90 respondents. Eight PLWH participated in the focus group. Most patients (77/90, 86%) reported having at least some experience using the Internet and most expressed interest in features offered by the portal. Notably, 70% (63/90) expressed some interest in being taught how to use it to communicate with their provider. Focus group themes reinforced these findings, but also voiced concern regarding access to private computers. CONCLUSIONS: Many PLWH in our sample have experience using computers and most are interested in PHR features. However, computer or broadband access and privacy are important barriers.

RESUMO

BACKGROUND: Persons living with HIV (PLWH) need practical tools to self-manage their condition. METHODS: We conducted a proof-of-concept study among PLWH to assess whether patients could learn to use a personal health record (PHR) on a hand-held device (iPod Touch) to manage their condition. We began individual trainings and later adapted this to group training. We assessed usability, acceptability and also effects on self-efficacy for treatment adherence using the HIV Treatment Adherence Self-Efficacy Scale (HIV-ASES). RESULTS: Nine PLWH participated in the individual training and 29 participated in the group sessions. The participants were largely middle aged, low-income and of racial/ethnic minorities. The sessions were well attended and participants fully engaged in tasks and shared learning. Most participants stated they intended to use the PHR and reported improved self-efficacy in treatment adherence (P = .05) particularly on the integration of treatment adherence into one's routine (P < .02). CONCLUSIONS: Training PLWH in use of a handheld PHR shows promise.

RESUMO

Cervical shedding of HIV-1 DNA may influence HIV-1 sexual transmission. HIV-1 DNA was detected in 250 (80%) of 316 and 207 (79%) of 259 cervical cytobrush specimens from 56 US and 80 Kenyan women, respectively. Plasma HIV-1 RNA concentration was associated with increased HIV-1 DNA shedding among US and Kenyan women. Kenyan women had higher cervicovaginal concentrations of proinflammatory interleukins (IL)-1ß, IL-6, IL-8, and anti-inflammatory secretory leukocyte protease inhibitor compared with US women (all P < 0.01). HIV-1 DNA shedding was associated with increased concentrations of IL-1ß and IL-6 and lower secretory leukocyte protease inhibitor among US women but not Kenyan women.
