RESUMEN

BACKGROUND & AIMS: Individuals who survive critical illness are often malnourished with inadequate oral nutrient intake after leaving the intensive care unit (ICU). Enteral nutrition (EN) improves nutrient intake but there is limited evidence on the impact of maintaining EN after discharge from the ICU. The objective of this exploratory study was to understand the association between EN maintenance after ICU and 30-day unplanned hospital re-admission, to inform on future prospective research into the effects of post-ICU nutrition. METHODS: This was a single-centre, retrospective study of ICU patients, requiring ventilation, who received EN for at least 3 days in ICU and were discharged to the ward. RESULTS: 102 patients met the inclusion criteria; 45 (44.1%) maintained EN and 57 (55.9%) discontinued EN after ICU discharge; there were no significant differences in demographics or clinical measures at ICU admission. Reason for EN discontinuation was documented in 38 (66.7%) patients, with 27 (71%) discontinuing EN due to a routine ward practice of feeding tube removal. Unplanned 30-day hospital re-admission occurred in 17 (16.7%) patients overall, 5 (11.1%) in the EN group and 12 (21.1%) in the non-EN group (crude odds ratio [OR] 0.47, 95% CI 0.15, 1.45, p = 0.188). After adjusting for age, sex, BMI and length of stay, there was a persistent trend to lower re-admission rates in the EN group (OR 0.37, 95% CI 0.09, 1.57, p = 0.176). CONCLUSIONS: EN maintenance after ICU discharge was associated with a trend to lower 30-day unplanned hospital re-admission rates. The clinically relevant reduction of about 50% in unplanned re-admission rates in this exploratory study warrants larger, prospective studies of post-ICU nutrition strategies based on clear discontinuation criteria to optimize nutrition and evaluate patient-centred outcomes.

RESUMEN

BACKGROUND: Hepatic steatosis, including nonalcoholic fatty liver disease (NAFLD), is common among people with HIV (PWH). We present baseline steatosis prevalence and cardiometabolic characteristics among REPRIEVE substudy participants. METHODS: REPRIEVE is an international, primary cardiovascular disease prevention, randomized, controlled trial of pitavastatin calcium vs. placebo among 7769 PWH ages 40-75 years on antiretroviral therapy (ART) and with low-to-moderate cardiovascular risk. A subset of participants underwent noncontrast computed tomography, with hepatic steatosis defined as mean hepatic attenuation less than 40 HU or liver/spleen ratio less than 1.0, and NAFLD defined as steatosis in the absence of frequent alcohol use or viral hepatitis. RESULTS: Of 687 evaluable persons, median age was 51 years, BMI 27 kg/m 2 , CD4 + T-cell count 607 cells/µl; 17% natal female sex, 36% Black, 24% Hispanic, and 98% HIV-1 RNA less than 400 copies/ml. Hepatic steatosis prevalence was 22% (149/687), and NAFLD 21% (96/466). Steatosis/NAFLD prevalence was higher in men and with older age, non-Black race, and higher BMI and waist circumference. Both were associated with BMI greater than 30 kg/m 2 , metabolic syndrome components, higher atherosclerotic cardiovascular disease (ASCVD) risk score, HOMA-IR, LpPLA-2 and hs-CRP, and lower high-density lipoprotein cholesterol. Of HIV-specific/ART-specific characteristics, only history of an AIDS-defining illness was more common among persons with steatosis/NAFLD. After adjusting for age, sex and race/ethnicity, BMI greater than 30 kg/m 2 , HOMA-IR greater than 2.0, Metabolic syndrome and each of its components were associated with NAFLD prevalence. CONCLUSION: In this cohort with controlled HIV and low-to-moderate cardiovascular risk, hepatic steatosis and NAFLD were common and associated with clinically relevant metabolic and inflammatory disturbances but not current HIV-related or ART-related factors.

RESUMEN

With improved access to antiretroviral therapy throughout the world, people are aging with HIV, and a large portion of the global population of people with HIV (PWH) is now age 50 or older. Older PWH experience more comorbidities, aging-related syndromes, mental health challenges, and difficulties accessing fundamental needs than the population of older adults without HIV. As a result, ensuring that older PWH are receiving comprehensive healthcare can often be overwhelming for both PWH and the providers. Although there is a growing literature addressing the needs of this population, gaps remain in care delivery and research. In this paper, we suggest seven key components to any healthcare program designed to address the needs of older people with HIV: management of HIV, comorbidity screening and treatment, primary care coordination and planning, attention to aging related-syndromes, optimization of functional status, support of behavioral health, and improved access to basic needs and services. We review many of the difficulties and controversies related to the implementation of these components, which include the absence of screening guidelines for this population and the challenges of care integration, and we suggest key next steps.

RESUMEN

Extracellular vesicles (EVs) are nanoparticles with a role in intercellular communication. Cell-free mitochondrial DNA (cf-mtDNA) has been associated with cognitive dysfunction in people with HIV (PWH). We conducted a nested case-control study to test the hypothesis that plasma EVs are associated with cf-mtDNA and cognitive dysfunction in older PWH. A machine learning-based model identified total EVs, including select EV subpopulations, as well as urine cf-mtDNA and 4-meter walk time carry power to predict the neurocognitive impairment. These features resulted in an AUC-ROC of 0.845 + / - 0.109 (0.615, 1.00).

RESUMEN

BACKGROUND: For some vaccine-preventable diseases, the immunologic response to vaccination is altered by a pregnant state. The effect of pregnancy on SARS-CoV-2 vaccine response remains unclear. OBJECTIVE: We sought to characterize the peak and longitudinal anti-S immunoglobulin G, immunoglobulin M, and immunoglobulin A responses to messenger RNA-based SARS-CoV-2 vaccination in pregnant persons and compare them with those in nonpregnant, reproductive-aged persons. STUDY DESIGN: We conducted 2 parallel prospective cohort studies among pregnant and nonpregnant persons who received SARS-CoV-2 messenger RNA vaccinations. Blood was collected at the time of first and second vaccine doses, 2 weeks post second dosage, and with serial longitudinal follow-up up to 41.7 weeks post vaccination initiation. Anti-S immunoglobulin M, immunoglobulin G, and immunoglobulin A were analyzed by enzyme-linked immunosorbent assay. We excluded those with previous evidence of SARS-CoV-2 infection by history or presence of antinucleocapsid antibodies. In addition, for this study, we did not include individuals who received a third or booster vaccine dosage during the study period. We also excluded pregnant persons who were not fully vaccinated (14 days post receipt of the second vaccine dosage) by time of delivery and nonpregnant persons who became pregnant through the course of the study. We studied the effect of gestational age at vaccination on the anti-S response using Spearman correlation. We compared the peak anti-S antibody responses between pregnant and nonpregnant persons using a Mann-Whitney U test. We visualized and studied the longitudinal anti-S antibody response using locally weighted scatterplot smoothing, Mann-Whitney U test, and mixed analysis of variance test. RESULTS: Data from 53 pregnant and 21 nonpregnant persons were included in this analysis. The median (interquartile range) age of the pregnant and nonpregnant participants was 35.0 (33.3-37.8) years and 36.0 (33.0-41.0) years, respectively. Six (11.3%) participants initiated vaccination in the first trimester, 23 (43.3%) in the second trimester, and 24 (45.3%) in the third trimester, with a median gestational age at delivery of 39.6 (39.0-40.0) weeks. The median (interquartile range) follow-up time from vaccine initiation to the last blood sample collected was 25.9 (11.9) weeks and 28.9 (12.9) weeks in the pregnant and nonpregnant cohort, respectively. Among pregnant persons, anti-S immunoglobulin G, immunoglobulin A, and immunoglobulin M responses were not associated with gestational age at vaccine initiation (all P>.05). The anti-S immunoglobulin G response at 2 weeks post second dosage was not statistically different between pregnant and nonpregnant persons (P>.05). However, the anti-S immunoglobulin M and immunoglobulin A responses at 2 weeks post second dosage were significantly higher in nonpregnant persons (P<.001 for both). The anti-S immunoglobulin G and immunoglobulin M levels 6 to 8 months after vaccine initiation fell to comparable proportions of the peak 2 weeks post second dosage antibody levels between pregnant and nonpregnant persons (immunoglobulin G P=.77; immunoglobulin M P=.51). In contrast, immunoglobulin A levels 6 to 8 months after vaccine initiation fell to statistically significantly higher proportions of peak 2 weeks post second dosage antibody levels in pregnant compared with nonpregnant persons (P=.002). Maternal anti-S immunoglobulin G levels were strongly correlated with umbilical cord anti-S immunoglobulin G levels (R=0.8, P<.001). CONCLUSION: The anti-S immunoglobulin A, immunoglobulin M, and immunoglobulin G response to SARS-CoV-2 vaccination in pregnancy is independent of gestational age of vaccine initiation. Maintenance of the immunoglobulin G response is comparable between pregnant and nonpregnant persons. The differential peak response of immunoglobulin M and immunoglobulin A and the differential decline of anti-S immunoglobulin A between pregnant and nonpregnant persons requires further investigation.

RESUMEN

OBJECTIVE: People living with HIV (PLWH) frequently experience pain, which often co-occurs with psychological symptoms and may impact functional outcomes. We investigated cross-sectional associations between pain, depressive symptoms, and inflammation, and then explored whether pain was related to poorer physical function among older PLWH. METHODS: We examined data from PLWH aged 54 to 78 years ( n = 162) recruited from a single outpatient program for a larger study on HIV and aging. Participants reported depressive symptoms (10-item Center for Epidemiological Studies Depression Scale) and then attended a biomedical visit in which they reported past-month pain (Medical Outcomes Study-HIV pain subscale), completed physical function assessments, and provided blood samples (assayed for interleukin 6, interferon-γ, tumor necrosis factor α, and C-reactive protein). Links between pain, depressive symptoms, inflammation, and physical function were tested using linear regression models. RESULTS: PLWH with greater depressive symptoms experienced more pain than did those with fewer depressive symptoms ( B = 1.31, SE = 0.28, p < .001), adjusting for age, sex, race, body mass index, smoking, disease burden, time since HIV diagnosis, and medication use. Higher composite cytokine levels were associated with worse pain ( B = 5.70, SE = 2.54, p = .027 in adjusted model). Poorer physical function indicators, including slower gait speed, weaker grip strength, recent falls, and prefrail or frail status, were observed among those with worse pain. Exploratory mediation analyses suggested that pain may partially explain links between depressive symptoms and several physical function outcomes. CONCLUSIONS: Pain is a potential pathway linking depressive symptoms and inflammation to age-related health vulnerabilities among older PLWH; longitudinal investigation of this pattern is warranted. PLWH presenting with pain may benefit from multidisciplinary resources, including behavioral health and geriatric medicine approaches.

RESUMEN

Efforts to cure HIV have focused on reactivating latent proviruses to enable elimination by CD8+ cytotoxic T-cells. Clinical studies of latency reversing agents (LRA) in antiretroviral therapy (ART)-treated individuals have shown increases in HIV transcription, but without reductions in virologic measures, or evidence that HIV-specific CD8+ T-cells were productively engaged. Here, we show that the SARS-CoV-2 mRNA vaccine BNT162b2 activates the RIG-I/TLR - TNF - NFκb axis, resulting in transcription of HIV proviruses with minimal perturbations of T-cell activation and host transcription. T-cells specific for the early gene-product HIV-Nef uniquely increased in frequency and acquired effector function (granzyme-B) in ART-treated individuals following SARS-CoV-2 mRNA vaccination. These parameters of CD8+ T-cell induction correlated with significant decreases in cell-associated HIV mRNA, suggesting killing or suppression of cells transcribing HIV. Thus, we report the observation of an intervention-induced reduction in a measure of HIV persistence, accompanied by precise immune correlates, in ART-suppressed individuals. However, we did not observe significant depletions of intact proviruses, underscoring challenges to achieving (or measuring) HIV reservoir reductions. Overall, our results support prioritizing the measurement of granzyme-B-producing Nef-specific responses in latency reversal studies and add impetus to developing HIV-targeted mRNA therapeutic vaccines that leverage built-in LRA activity.

RESUMEN

BACKGROUND: Older people with HIV experience more comorbidities and geriatric syndromes than their HIV-negative peers, perhaps due to residual inflammation despite suppressive antiretroviral therapy. Cell-free mitochondrial DNA (cfmtDNA) released during necrosis-mediated cell death potentially acts as both mediator and marker of inflammatory dysregulation. Thus, we evaluated plasma cfmtDNA as a potential biomarker of geriatric syndromes. METHODS: Participants underwent the Montreal Cognitive Assessment (MoCA), frailty testing, and measurement of plasma cfmtDNA by qPCR and inflammatory markers including C-reactive protein, interleukin-6 (IL-6), interferon gamma, and tumor necrosis factor alpha in this cross-sectional study. RESULTS: Across 155 participants, the median age was 60 years (Q1, Q3: 56, 64), one-third were female, and 92% had HIV-1 viral load <200 copies/mL. The median MoCA score was 24 (21, 27). The plasma cfmtDNA level was higher in those with cognitive impairment (MoCA <23) ( P = 0.02 by the t test) and remained significantly associated with cognitive impairment in a multivariable logistic regression model controlling for age, sex, race, CD4 T-cell nadir, HIV-1 viremia, and depression. Two-thirds of participants met the criteria for a prefrail or frail state; higher plasma cfmtDNA was associated with slow walk and exhaustion but not overall frailty state. Cognitive dysfunction was not associated with C-reactive protein, IL-6, interferon gamma, or tumor necrosis factor alpha, and frailty state was only associated with IL-6. CONCLUSIONS: Plasma cfmtDNA may have a role as a novel biomarker of cognitive dysfunction and key components of frailty. Longitudinal investigation of cfmtDNA is warranted to assess its utility as a biomarker of geriatric syndromes in older people with HIV.

RESUMEN

OBJECTIVES: People living with human immunodeficiency virus (PLWH) treated with antiretrovirals have life spans similar to their HIV-negative peers. Yet, they experience elevated inflammation-related multimorbidity. Drawing on biopsychosocial determinants of health may inform interventions, but these links are understudied in older PLWH. We investigated cross-sectional relationships between psychosocial factors (mood, loneliness, and stigma), inflammatory markers, and age-related health outcomes among 143 PLWH aged 54-78 years. METHOD: Participants provided blood samples for serum cytokine and C-reactive protein (CRP) analyses, completed surveys assessing psychosocial factors and health, and completed frailty assessments. Regression models tested relationships between key psychosocial-, inflammation, and age-related health variables, adjusting for relevant sociodemographic and clinical factors. RESULTS: Participants with more depressive symptoms had higher composite cytokine levels than those with fewer depressive symptoms (ß = 0.22, t(126) = 2.71, p = .008). Those with higher cytokine levels were more likely to be prefrail or frail (adjusted odds ratio = 1.72, 95% confidence interval = 1.01-2.93) and reported worse physical function (ß = -0.23, t(129) = -2.64, p = .009) and more cognitive complaints (ß = -0.20, t(129) = -2.16, p = .03) than those with lower cytokine levels. CRP was not significantly related to these outcomes; 6-month fall history was not significantly related to inflammatory markers. DISCUSSION: Novel approaches are needed to manage comorbidities and maximize quality of life among older PLWH. Illustrating key expected biopsychosocial links, our findings highlight several factors (e.g., depressive symptoms, poorer physical function) that may share bidirectional relationships with chronic inflammation, a key factor driving morbidity. These links may be leveraged to modify factors that drive excessive health risk among older PLWH.

RESUMEN

As they age, people living with HIV (PLWH) experience greater rates of inflammation-related health conditions compared to their HIV-negative peers. Because early life adversity can exaggerate proinflammatory effects of later physiological challenges, inflammation may be higher among PLWH with these combined risks, which could inform intervention approaches to mitigate multimorbidity. In this cross-sectional analysis, we investigated individual and combined effects of childhood sexual abuse (CSA) history and physiological burden (Veterans Aging Cohort Study Index scores) on serum cytokine and C-reactive protein (CRP) levels among PLWH. Participants (n â€‹= â€‹131; age 54 and older) were patients at an outpatient HIV clinic who completed a psychosocial survey and biomedical research visit as part of a larger study. 93% were virally suppressed, and 40% reported experiencing sexual abuse in childhood. Composite cytokine levels (summarizing IL-6, TNF-α, IFN-γ), CRP, and disease burden did not differ significantly between those who had a history of CSA and those who did not. Participants with greater disease burden had higher composite cytokine levels (r â€‹= â€‹0.29, p â€‹= â€‹0.001). The disease burden by CSA interaction effect was a significant predictor of composite cytokine levels (but not CRP), and remained significant after controlling for age, sex, race, BMI, anti-inflammatory medication use, selective serotonin reuptake inhibitor use, depressive symptoms, and smoking status (F(1, 114) â€‹= â€‹5.68, p â€‹= â€‹0.02). In follow-up simple slopes analysis, greater disease burden was associated with higher cytokine levels among those with CSA history (b â€‹= â€‹0.03, SE â€‹= â€‹0.008, p<0.001), but not among those without CSA history. Further, in the context of greater disease burden, individuals with a CSA history tended to have higher cytokine levels than those without a CSA history (b â€‹= â€‹0.38, SE â€‹= â€‹0.21, p â€‹= â€‹0.07). These data suggest that the physiological sequelae of childhood trauma may persist into older age among those with HIV. Specifically, links between physiological burden and inflammation were stronger among survivors of CSA in this study. The combined presence of CSA history and higher disease burden may signal a greater need for and potential benefit from interventions to reduce inflammation, an area for future work.

RESUMEN

BACKGROUND: Older adults with HIV (OAH) experience more comorbidities and geriatric syndromes than their HIV-negative peers, perhaps because of chronic inflammation. Cell-free mitochondrial DNA (cfmtDNA) released from cells undergoing necrosis-mediated cell death potentially acts as both a mediator and marker of inflammatory dysregulation. We hypothesized that urinary cfmtDNA would be associated with frailty, body composition, and fall history in OAH. METHODS: OAH completed frailty testing, a psychosocial survey, body composition assessment, and measurement of urine cfmtDNA and urine albumin:creatinine in this cross-sectional study. Urine cfmtDNA was measured by quantative polymerase chain reaction and normalized to urinary creatinine. RESULTS: Across 150 participants, the mean age was 61 years (SD 6 years), half identified as Black, one-third were women, and 93% had HIV-1 viral load <200 copies/mL. Two-thirds met criteria for a prefrail or frail state. Those with unintentional weight loss had higher urine cfmtDNA concentrations (P = 0.03). Higher urine cfmtDNA was inversely associated with the skeletal muscle index (ß = -0.19, P < 0.01) and fat mass index (ß = -0.08, P = 0.02) in separate multiple linear regression models adjusted for age, sex, and presence of moderate-severe albuminuria. CONCLUSIONS: In this cross-sectional study of OAH, higher levels of urine cfmtDNA were more common in subjects with less robust physical condition, including unintentional weight loss and less height-scaled body mass of fat and muscle. These findings suggest urine cfmtDNA may reflect pathophysiologic aging processes in OAH, predisposing them to geriatric syndromes. Longitudinal investigation of urine cfmtDNA as a biomarker of geriatric syndromes is warranted.

RESUMEN

OBJECTIVE: Characterising the perceptions of groups most affected by HIV is fundamental in establishing guidelines for biomedical advancement. Although Brazil has successfully fought HIV/AIDS through several measures, transgender women still have a likelihood of HIV infection 55 times higher than the general population. This study aimed to better understand the perception and awareness of HIV cure research among the trans-identifying population in São Paulo, Brazil, and to determine factors that motivate or discourage participation in HIV cure studies. SETTING: This cross-sectional study analysed data collected from a questionnaire administered to 118 transgender women and travestis at 5 sites within the city of São Paulo. It uses quantitative methodology to describe the perspectives of transgender and travesti people in relation to HIV cure research and the context in which such perspectives are produced. RESULTS: Of 118 participants, most participants (73%) had some knowledge of HIV cure research and were most willing to participate in online surveys (52%), interviews (52%), focus groups (52%) and studies involving blood draws (57%). Those with a higher education or employment status were more likely to agree that someone had been cured of HIV, people living with HIV are discriminated against, and more information about HIV cure research is needed before the community embraces it. Only 55% of participants completely trusted their physician. The biggest motivational factors included gaining additional knowledge about HIV infection (77%) and the potential for a longer, healthier life for all (73%). CONCLUSIONS: As a primary analysis of HIV cure attitudes among the transgender and travesti population as well as the social context in which they are formed, this study identifies opportunities to strengthen the dialogue and develop more educational collaborations between scientific investigators, community educators and the trans-identifying population to ensure that HIV cure research is inclusive of diverse perspectives.

RESUMEN

BACKGROUND: The spread of SARS-CoV-2 and the COVID-19 pandemic have caused significant morbidity and mortality worldwide. The clinical characteristics and outcomes of hospitalized patients with SARS-CoV-2 and HIV co-infection remain uncertain. METHODS: We conducted a matched retrospective cohort study of adults hospitalized with a COVID-19 illness in New York City between March 3, 2020, and May 15, 2020. We matched 30 people with HIV (PWH) with 90 control group patients without HIV based on age, sex, and race/ethnicity. Using electronic health record data, we compared demographic characteristics, clinical characteristics, and clinical outcomes between PWH and control patients. RESULTS: In our study, the median age (interquartile range) was 60.5 (56.6-70.0) years, 20% were female, 30% were black, 27% were white, and 24% were of Hispanic/Latino/ethnicity. There were no significant differences between PWH and control patients in presenting symptoms, duration of symptoms before hospitalization, laboratory markers, or radiographic findings on chest x-ray. More patients without HIV required a higher level of supplemental oxygen on presentation than PWH. There were no differences in the need for invasive mechanical ventilation during hospitalization, length of stay, or in-hospital mortality. CONCLUSIONS: The clinical manifestations and outcomes of COVID-19 among patients with SARS-CoV-2 and HIV co-infection were not significantly different than patients without HIV co-infection. However, PWH were hospitalized with less severe hypoxemia, a finding that warrants further investigation.

RESUMEN

Objectives: To determine links between objectively and subjectively measured physical function and cognitive function among HIV-positive older adults, a growing yet understudied group with elevated risk for multimorbidity. Methods: At a biomedical research visit, 162 participants completed objective tests of gait speed (4-m walk), grip strength (dynamometer), and cognitive function (Montreal Cognitive Assessment, MoCA) and reported their well-being (Medical Outcomes Study-HIV survey). Results: Those with faster gait speed had better overall cognitive function than those with slower gait speed (b = 3.98, SE = 1.30, p = .003) in an adjusted regression model controlling for age, sex, race, height, preferred language, and assistive device use. Grip strength was not significantly associated with overall cognitive function. Self-rated cognitive function was weakly related to MoCA scores (r = .26) and gait speed (r = .14) but was strongly associated with emotional well-being (r = .53). Discussion: These observed, expected connections between physical and cognitive function could inform intervention strategies to mitigate age-related declines for older adults with HIV.

: Globally, the proportion of older people living with HIV (PLWH) is growing and the burden of noncommunicable diseases, including cardiac and renal disease, is increasing. There are few studies of renal disease and cardiac risk in older PLWH. This study investigates the relationship between albuminuria and cardiac risk as estimated by the Atherosclerotic Cardiovascular Disease 10-year risk calculator. We report that albuminuria is associated with a higher Atherosclerotic Cardiovascular Disease risk score in both diabetic and nondiabetic older PLWH.

RESUMEN

BACKGROUND: Protein deficits have been associated with longer intensive care unit (ICU) stays and increased mortality. Current view suggests if protein goals are met, meeting full energy targets may be less important and prevent deleterious effects of overfeeding. We proposed a very-high protein (VHP) enteral nutrition (EN) formula could provide adequate protein, without overfeeding energy, in the first week of critical illness. METHODS: This was a retrospective study of medical/surgical ICU patients receiving EN exclusively for ≥5 days during the first week of ICU admission. Twenty participants received standard EN; 20 participants received the VHP-EN formula (1 kcal/mL, 37% protein). Protein and energy prescribed/received, gastrointestinal tolerance, and feeding interruptions were examined. RESULTS: Forty ICU patients [average Acute Physiology and Chronic Health Evaluation II score of 20.1] were included. Protein prescribed and received was significantly higher in the VHP group vs the standard EN group (135.5 g/d ± 22.9 vs 111.4 g/d ± 25; P = .003 and 112.2 g/d ± 27.8 vs 81.7 g/d ± 16.7, respectively; P = .002). Energy prescribed and received was similar between groups (1696 kcal/d ± 402 vs 1893 kcal/d ± 341, respectively; P = .101 and 1520 kcal/d ± 346 vs 1506 ± 380 kcal/d; P = .901). There were no differences in EN tolerance (P = .065) or feeding interruptions (P = .336). CONCLUSIONS: Use of a VHP formula in ICU patients resulted in higher protein intakes without overfeeding energy or use of modular protein in the first 5 days of exclusive EN.

RESUMEN

Diabetes mellitus (DM) is associated with expansion of proinflammatory lymphocyte subsets. We investigated the relationship of total white blood cell (WBC) count and lymphocyte subsets with incident DM in the Women's Interagency HIV Study (WIHS). Higher CD4 and CD8 T cell counts, lymphocyte count, and total WBC count were associated with incident DM among both women with and without HIV, although the association of CD8 was not statistically significant among women without HIV.
