Convenience, efficacy, safety, and durability of INSTI-based antiretroviral therapies: evidence from the Italian MaSTER cohort. Eur J Med Res 2023; 28:292. [PMID: 37596688 PMCID: PMC10436514 DOI: 10.1186/s40001-023-01276-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Accepted: 08/08/2023] [Indexed: 08/20/2023] Open
Abstract
BACKGROUND Integrase strand transferase inhibitors (INSTI), including raltegravir (RAL), elvitegravir (ELV), and dolutegravir (DTG), have demonstrated better efficacy and tolerability than other combination antiretroviral therapy (cART) classes in clinical trials; however, studies of sustainability of INSTI-containing therapy in the long-term are sparse. The purpose of this study was to provide an epidemiological overview comparing the outcome performance of different INSTI-based regimens longitudinally, including the metrics of efficacy, safety, convenience, and durability among a large, nationally representative cohort of persons living with HIV in Italy. METHODS We selected subjects in the MaSTER cohort (an Italian multicenter, hospital-based cohort established in the mid-1990s that currently has enrolled over 24,000 PLWH) who initiated an INSTI-based regimen either when naïve or following a regimen switch. Cox proportional hazards regression models were fitted to evaluate associations between therapy interruptions and age, sex, nationality, transmission risk group, viral suppression status, CD4 + T-cell count, diagnosis year, cART status (naïve or experienced), and hepatitis coinfection. Results were stratified by cART INSTI type. RESULTS There were 8173 participants who initiated an INSTI-based cART regimen in the MaSTER cohort between 2009 and 2017. The population was majority male (72.6%), of Italian nationality (88.6%), and cART-experienced (83.0%). Mean age was 49.7 (standard deviation: 13.9) years. In total, interruptions of the 1st INSTI-based treatment were recorded in 34% of cases. The most frequently cited reason for interruption among all three drug types was safety problems. In the survival analysis, past history of cART use was associated with higher hazards of interruption due to poor efficacy for all three drug types when compared to persons who were cART naïve. Non-viral suppression and CD4 + T-cell count < 200/mm3 at baseline were associated with higher hazards of interruption due to efficacy, safety, and durability reasons. Non-Italian nationality was linked to higher hazards of efficacy interruption for RAL and EVG. Age was negatively associated with interruption due to convenience and positively associated with interruption due to safety reasons. People who injects drugs (PWID) were associated with higher hazards of interruption due to convenience problems. Hepatitis coinfection was linked to higher hazards of interruption due to safety concerns for people receiving RAL. CONCLUSION One-third of the population experienced an interruption of any drugs included in INSTI therapy in this study. The most frequent reason for interruption was safety concerns which accounted for one-fifth of interruptions among the full study population, mainly switched to DTG. The hazard for interruption was higher for low baseline CD4 + T-cell counts, higher baseline HIV-RNA, non-Italian nationality, older age, PWID and possible co-infections with hepatitis viruses. The risk ratio was higher for past history of cART use compared to persons who were cART naive, use of regimens containing 3 drugs compared to regimens containing 2 drugs. Durability worked in favor of DTG which appeared to perform better in this cohort compared to RAL and EVG, though length of follow-up was significantly shorter for DTG. These observational results need to be confirmed in further perspective studies with longer follow-up.

Efficacy, Convenience, Safety and Durability of DTG-Based Antiretroviral Therapies: Evidence from a Prospective Study by the Italian MaSTER Cohort. Viruses 2023; 15:v15040924. [PMID: 37112904 PMCID: PMC10145592 DOI: 10.3390/v15040924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/31/2023] [Accepted: 04/04/2023] [Indexed: 04/29/2023] Open
Abstract
Background: Dolutegravir (DTG) is recommended by international guidelines as a main component of an optimal initial regimen of cART (combination antiretroviral treatment) in people living with HIV (PLWH) and in case of switching for failure or optimization strategies. However, studies on the performance of DTG-containing regimens and indications for switching therapies in the long term are sparse. The purpose of this study was to evaluate prospectively the performance of DTG-based regimens, using the metrics of "efficacy", "safety", "convenience" and ''durability'', among a nationally representative cohort of PLWH in Italy. Methods: We selected all PLWH in four centers of the MaSTER cohort who initiated a DTG-based regimen either when naïve or following a regimen switch between 11 July 2018 and 2 July 2021. Participants were followed until the outcomes were recorded or until the end of the study on 4 August 2022, whichever occurred first. Interruption was reported even when a participant switched to another DTG-containing regimen. Survival regression models were fitted to evaluate associations between therapy performance and age, sex, nationality, risk of HIV transmission, HIV RNA suppression status, CD4+ T-cell count, year of HIV diagnosis, cART status (naïve or experienced), cART backbone and viral hepatitis coinfection. Results: There were 371 participants in our cohort who initiated a DTG-based cART regimen in the time frame of the study. The population was predominantly male (75.2%), of Italian nationality (83.3%), with a history of cART use (80.9%), and the majority initiated a DTG-based regimen following a switch strategy in 2019 (80.1%). Median age was 53 years (interquartile range (IQR): 45-58). Prior cART regimen was based mostly on a combination of NRTI drugs plus a PI-boosted drug (34.2%), followed by a combination of NRTIs plus an NNRTI (23.5%). Concerning the NRTI backbone, the majority comprised 3TC plus ABC (34.5%), followed by 3TC alone (28.6%). The most reported transmission risk factor was heterosexual intercourse (44.2%). Total interruptions of the first DTG-based regimen were registered in 58 (15.6%) participants. The most frequent reason for interruption was due to cART simplification strategies, which accounted for 52%. Only 1 death was reported during the study period. The median time of total follow-up was 556 days (IQR: 316.5-722.5). Risk factors for poor performance of DTG-containing-regimens were found to be: a backbone regimen containing tenofovir, being cART naïve, having detectable HIV RNA at baseline, FIB-4 score above 3.25 and having a cancer diagnosis. By contrast, protective factors were found to be: higher CD4+ T-cell counts and higher CD4/CD8 ratio at baseline. Conclusion: DTG-based regimens were used mainly as a switching therapy in our cohort of PLWH who had undetectable HIV RNA and a good immune status. In this type of population, the durability of DTG-based regimens was maintained in 84.4% of participants with a modest incidence of interruptions mostly due to cART simplification strategies. The results of this prospective real-life study confirm the apparent low risk of changing DTG-containing regimens due to virological failure. They may also help physicians to identify people with increased risk of interruption for different reasons, suggesting targeted medical interventions.

Abstract
HIV infection predisposes people to cancer, including AIDS‐defining cancers, such as Kaposi sarcoma, and a broad range of non‐AIDS‐defining cancers. Here we report a case with rare coexistence of HIV and thymoma, and summarize all the comorbid cases that currently exist. We found that in all the cases reported, thymoma occurred when CD4+ counts were within a normal range, but the immune response in peripheral T‐cell repertoire remains unknown. In our case, an overview of the immune system under this complicated situation is given for the first time by showing the lymphocyte subpopulations in the blood and the immune cell distribution of the thymoma. This case expands the scope of non‐AIDS‐defining cancers, and provides insight into the influence of the immune system under two immunocompromising conditions, HIV infection and thymoma.

Decrease in Incidence Rate of Hospitalizations Due to AIDS-Defining Conditions but Not to Non-AIDS Conditions in PLWHIV on cART in 2008-2018 in Italy. J Clin Med 2021; 10:jcm10153391. [PMID: 34362172 PMCID: PMC8347382 DOI: 10.3390/jcm10153391] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 07/20/2021] [Accepted: 07/29/2021] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND We aimed to describe the change in the incidence and causes of hospitalization between 2008 and 2018 among persons living with HIV (PLWHIV) who started antiretroviral therapy (ART) from 2008 onwards in Italy. METHODS We included participants in the ICONA (Italian Cohort Naïve Antiretrovirals) cohort who started ART in 2008. All the hospitalizations occurring during the first 30 days from the start of ART were excluded. Hospitalizations were classified as due to: AIDS-defining conditions (ADC), non-ADC infections and non-infections/non-ADC (i.e., cardiovascular, pulmonary, renal-genitourinary, cancers, gastrointestinal-liver, psychiatric and other diseases). Comparisons of rates across time were assessed using Poisson regression. The Poisson multivariable model evaluated risk factors for hospitalizations, including both demographic and clinical characteristics. RESULTS A total of 9524 PLWHIV were included; 6.8% were drug users, 48.9% men-who-have sex with men (MSM), 39.6% heterosexual contacts; 80.8% were males, 42.3% smokers, 16.6% coinfected with HCV and 6.8% with HBV (HBsAg-positive). During 36,157 person-years of follow-up (PYFU), there were 1058 hospitalizations in 747 (7.8%) persons; they had HIV-RNA >50 copies mL in 34.9% and CD4 < 200/mmc in 27%. Causes of hospitalization were 23% ADC, 22% non-ADC infections, 55% non-infections/non-ADC (11% cancers; 9% gastrointestinal-liver; 6% cardiovascular; 5% renal-genitourinary; 5% psychiatric; 4% pulmonary; 15% other). Over the study period, the incidence rate (IR) decreased significantly (from 5.8 per 100 PYFU in 2008-2011 to 2.21 per 100 PYFU in 2016-2018). Age > 50 years, intravenous drug use (IDU), family history of cardiovascular disease, HIV-RNA > 50, CD4 < 200, were associated with a higher hospitalization risk. CONCLUSIONS In our population of PLWHIV, the rate of hospitalization decreased over time.

Immunophenotypic characterization of TCR γδ T cells and MAIT cells in HIV-infected individuals developing Hodgkin's lymphoma. Infect Agent Cancer 2021; 16:24. [PMID: 33865435 PMCID: PMC8052713 DOI: 10.1186/s13027-021-00365-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Accepted: 04/08/2021] [Indexed: 12/12/2022] Open
Abstract
Background Despite successful combined antiretroviral therapy (cART), the risk of non-AIDS defining cancers (NADCs) remains higher for HIV-infected individuals than the general population. The reason for this increase is highly disputed. Here, we hypothesized that T-cell receptor (TCR) γδ cells and/or mucosal-associated invariant T (MAIT) cells might be associated with the increased risk of NADCs. γδ T cells and MAIT cells both serve as a link between the adaptive and the innate immune system, and also to exert direct anti-viral and anti-tumor activity. Methods We performed a longitudinal phenotypic characterization of TCR γδ cells and MAIT cells in HIV-infected individuals developing Hodgkin’s lymphoma (HL), the most common type of NADCs. Cryopreserved PBMCs of HIV-infected individuals developing HL, matched HIV-infected controls without (w/o) HL and healthy controls were used for immunophenotyping by polychromatic flow cytometry, including markers for activation, exhaustion and chemokine receptors. Results We identified significant differences in the CD4+ T cell count between HIV-infected individuals developing HL and HIV-infected matched controls within 1 year before cancer diagnosis. We observed substantial differences in the cellular phenotype mainly between healthy controls and HIV infection irrespective of HL. A number of markers tended to be different in Vδ1 and MAIT cells in HIV+HL+ patients vs. HIV+ w/o HL patients; notably, we observed significant differences for the expression of CCR5, CCR6 and CD16 between these two groups of HIV+ patients. Conclusion TCR Vδ1 and MAIT cells in HIV-infected individuals developing HL show subtle phenotypical differences as compared to the ones in HIV-infected controls, which may go along with functional impairment and thereby may be less efficient in detecting and eliminating malignant cells. Further, our results support the potential of longitudinal CD4+ T cell count analysis for the identification of patients at higher risk to develop HL.

Abstract
BACKGROUND It is unknown if the carcinogenic effect of smoking is influenced by CD4+ cell count and viral load in persons living with HIV. MATERIAL AND METHODS RESPOND participants with known smoking status were included. Poisson regression adjusting for baseline confounders investigated the interaction between current CD4+/viral load strata [good (CD4+ cell count ≥500 cells/μl and viral load <200 copies/ml], poor [CD4+ cell count ≤350 cells/μl and viral load >200 copies/ml] and intermediate [all other combinations]), smoking status and all cancers, non-AIDS defining cancers (NADCs), smoking-related cancers (SRCs) and infection-related cancers (IRCs). RESULTS Out of 19 602 persons, 41.3% were never smokers, 44.4% current and 14.4% previous smokers at baseline. CD4+/viral load strata were poor in 3.4%, intermediate in 44.8% and good in 51.8%. There were 513 incident cancers; incidence rate 6.9/1000 person-years of follow-up (PYFU) [95% confidence interval (95% CI) 6.3-7.5]. Current smokers had higher incidence of all cancer (adjusted incidence rate ratio 1.45; 1.17-1.79), NADC (1.65; 1.31-2.09), SRC (2.21; 1.53-3.20) and IRC (1.38; 0.97-1.96) vs. never smokers. Those with poor CD4+/viral load had increased incidence of all cancer (5.36; 95% CI 3.71-7.75), NADC (3.14; 1.92-5.14), SRC (1.82; 0.76-4.41) and IRC (10.21; 6.06-17.20) vs. those with good CD4+/viral load. There was no evidence that the association between smoking and cancer subtypes differed depending on the CD4+/viral load strata (P > 0.1, test for interaction). CONCLUSION In the large RESPOND consortium, the impact of smoking on cancer was clear and reducing smoking rates should remain a priority. The association between current immune deficiency, virological control and cancer was similar for never smokers, current smokers and previous smokers suggesting similar carcinogenic effects of smoking regardless of CD4+ cell count and viral load.

Impact of Advanced HIV Disease on Quality of Life and Mortality in the Era of Combined Antiretroviral Treatment. J Clin Med 2021; 10:jcm10040716.

Abstract
Currently, AIDS or severe immunodeficiency remains as a challenge for people with HIV (PWHIV) and healthcare providers. Our purpose was to analyze the impact of advanced HIV disease (AHD) on mortality, life expectancy and health-related quality of life (HRQoL). We reviewed cohort studies and meta-analyses conducted in middle- and high-income countries. To analyze HRQoL, we selected studies that reported overall health and/or physical/mental health scores on a validated HRQoL instrument. AIDS diagnosis supposes a higher risk of mortality during the first six months, remaining higher for 48 months. It has been reported that cancer and cardiovascular disease persist as frequent causes of mortality in PWHIV, especially those with previous or current AHD. PWHIV who initiate combination antiretroviral therapy (cART) with CD4 < 200 cells/µL have significantly lower estimated life expectancy than those with higher counts. AHD is associated with lower HRQoL, and a worse physical health or mental health status. AIDS and non-AIDS defining events are significant predictors of a lower HRQoL, especially physical health status. AHD survivors are in risk of mortality and serious comorbidities, needing special clinical attention and preventive programs for associated comorbidities. Their specific needs should be reflected in HIV guidelines.

Abstract
BACKGROUND AND OBJECTIVE After the introduction of antiretroviral therapy, a decrease in AIDS defining cancers (ADCs) is observed, while non-AIDS-defining cancers (NADCs) have increased in HIV-infected patients (HIP). We have little information about the prognosis and associated risk factors. We studied survival and its relationship with immunodeficiency after the diagnosis of ADC or NADC. MATERIAL AND METHODS Observational, retrospective study of 788 HIP of whom 133 developed a malignancy between 2000-2016. Malignancies were divided into ADCs or NADCs and degree of immunodeficiency according to the CD4 T lymphocyte count> or </=200/mm3. Survival was estimated according to the Kaplan Meier method, multivariate COX regression analysis and compared with the log-rank test. RESULTS 149 malignancies were diagnosed in 133 HIP: 41.4% ADCs and 58.6 NADCs. The most frequent tumour was NHL (21.1%), followed by lung carcinoma (15%). HCV was positive in 50.4% and 65.4% were smokers. Thirty-nine point one percent had a CD4 T lymphocyte count </=200/mm3, being 60% in the case of ADCs while in NADCs it was 38.5%. CD4 T lymphocyte count </=200/mm3 is significantly associated with lower survival after diagnosis of ADCs(p=.031) and NADCs (p=.005). CONCLUSIONS The most frequent types of tumours in HIP differ from those in the general population, probably due to oncogenic risk factors. CD4 T lymphocyte count </=200/mm3 is a risk factor related to worse prognosis after NADC or ADC diagnosis.

Abstract
OBJECTIVES Restricted capacity for viral load (VL) testing is a major obstacle for antiretroviral therapy (ART) programmes in high-burden regions. Algorithms for targeted VL testing could help allocate laboratory resources rationally. We validated the performance of the Viral Load Testing Criteria (VLTC), an algorithm with satisfactory performance in derivation (sensitivity 91%, specificity 43%). METHODS HIV-positive adults who had been receiving first-line ART for ≥12 months at three Ethiopian public ART clinics were included. Healthcare providers collected data on variables of the VLTC: current CD4 count, mid-upper arm circumference (MUAC) and self-reported treatment interruption. VL testing was performed in parallel. Performance of the algorithm for identification of patients with VL ≥ 1000 copies/ml was evaluated. RESULTS Of 562 patients (female 62%, median ART duration 92 months), 33 (6%) had VL ≥ 1000 copies/ml. Sensitivity for the VLTC was 85% (95% CI, 68-95), specificity 60% (95% CI, 55-64), positive predictive value 12% (95% CI, 10-14) and negative predictive value 98% (95% CI, 97-99). Use of the algorithm would reduce the number of VL tests required by 57%. Misclassification occurred in 5/33 (15%) of subjects with VL ≥ 1000 copies/ml. CONCLUSION In validation, the VLTC performed similarly well as derivation. Use of the VLTC may be considered for targeted VL testing for ART monitoring in high-burden regions.

Abstract
BACKGROUND Although Sub-Saharan Africa accounts for 71% of the people living with Human Immunodeficiency Virus (HIV) worldwide and Cameroon accounts for about 2% of them, the role of HIV-induced immunodeficiency and exposure to Antiretroviral Therapy (ART) in the occurrence of cancers in Cameroon has scarcely been examined. The aim of our study was to determine the incidence of cancers in HIV patients and to determine the role of CD4+cell count in the onset of cancers. METHODS A retrospective cohort study was carried out from medical records of people confirmed to be HIV-positive from 01 July 2003 to 30 April 2013. Potential risk factors were studied by Cox proportional hazards model. RESULTS A total of 1768 patients were included in the analysis and 53 cases of cancer were diagnosed with an incidence rate of 7.4 per 1000 person-year of follow-up (95% CI; 5.4-9.4 per 1000 person-years of follow-up). Immunosuppression and exposure to ART were identified as factors associated with the occurrence of cancers in this population. Current CD4+cell count was the most important risk factor for cancer. Risk of cancer ranged from 15.51 (95% CI; 5.45-44.1; P<0.001) for a CD4+ cell count<50 cells/mm3 to 2.87 (95% CI; 1.14-7.2; P=0.025) for a CD4+ level between 350-499 cells/mm3. CONCLUSION Our study showed that the incidence rate of cancers is high among HIV patients in Cameroon. This incidence seems to correlate positively with the latest CD4+cell count and negatively with initiation of antiretroviral treatment.

Abstract
Investigation of the relationship between high-density lipoprotein-cholesterol (HDL-c) and the risk of developing cancer in a prospective cohort of human immunodeficiency virus (HIV)-infected patients.The Italian Cohort of Antiretroviral-naïve Patients Foundation Cohort is an Italian multicenter observational study recruiting HIV-positive patients while still antiretroviral treatment-naïve, regardless of the reason since 1997.Patients with at least 1 HDL-c value per year since enrollment and one such value before antiretroviral treatment initiation were included. HDL-c values were categorized as either low (<39 mg/dL in males or <49 mg/dL in females) or normal. Cancer diagnoses were classified as AIDS-defining malignancies (ADMs) or non-AIDS-defining malignancies (NADMs). Kaplan-Meier curves and Cox proportional-hazards regression models were used.Among 4897 patients (13,440 person-years of follow-up [PYFU]), 104 diagnoses of cancer were observed (56 ADMs, 48 NADMs) for an overall incidence rate of 7.7 (95% confidence interval [CI] 6.3-9.2) per 1000 PYFU.Low HDL-c values at enrollment were associated with higher risk both of cancer (crude hazard ratio [HR] 1.72, 95% CI 1.16-2.56, P = 0.007) and of NADM (crude HR 2.50, 95% CI 1.35-4.76, P = 0.003). Multivariate analysis showed that the risk of cancer diagnosis was higher in patients with low HDL-c values (adjusted HR [AHR] 1.87, 95% CI 1.18-2.95, P = 0.007) in older patients, those patients more recently enrolled, and in those with low current cluster of differentiation 4+ levels, and/or high current HIV-ribonucleic acid.The multivariate model confirmed an association between HDL-c (AHR 2.61, 95% CI 1.40-4.89, P = 0.003) and risk of NADM.Low HDL-c is an independent predictor of cancer in HIV-1-infected subjects.

History of AIDS in HIV-Infected Patients Is Associated With Higher In-Hospital Mortality Following Admission for Acute Myocardial Infarction and Stroke. J Infect Dis 2016; 213:1955-61.

Abstract
BACKGROUND Although human immunodeficiency virus (HIV)-infected persons are at increased risk for major cardiovascular events, short-term prognosis after these events is unclear. METHODS To determine the association between HIV infection and acute myocardial infarction (AMI) and stroke outcomes, we analyzed hospital discharge data from the Nationwide Inpatient Sample (NIS) between 2002 and 2012. Multivariable logistic regression was used to evaluate the association between HIV infection and in-hospital death after AMI or stroke. RESULTS Overall, 18 369 785 AMI/stroke hospitalizations were included in the analysis. Patients with a history of AIDS were significantly more likely than uninfected patients to die during hospitalization after admission for AMI or stroke (odds ratio, 3.03 [95% confidence interval {CI}, 1.71-5.38] for AMI and 2.59 [95% CI, 1.97-3.41] for stroke). Additionally, patients with AIDS were more likely than HIV-uninfected patients to be discharged to nonhospital inpatient facilities after admission for AMI (OR, 3.14 [95% CI, 1.72-5.74]) or stroke (OR, 1.45; 95% CI, 1.12-1.87). There was a minimal difference in either outcome between HIV-infected patients without a history of AIDS and uninfected patients. CONCLUSIONS Patients with a history of AIDS were significantly more likely than uninfected patients to die during hospitalization after admission for AMI or stroke. This disparity was not observed when infected patients without a history of AIDS were compared to uninfected patients, implying that preserving immune function may improve cardiovascular outcomes in HIV-infected persons.

Abstract
BACKGROUND We describe older (>50 years) HIV-infected adults after antiretroviral therapy (ART) initiation, evaluating immunological recovery by age category, considering individual trajectories based on the pretreatment CD4. We also describe mortality on ART and its risk factors by age category including the contribution of poor immunological recovery at a large urban clinic in Kampala, Uganda. METHODS We performed a cohort analysis of adult (>18 years) HIV-infected patients who initiated ART between January 1, 2004 and January 3, 2012. Immunological response was evaluated using mixed-effects linear regression. We described mortality using Kaplan-Meier survival methods analyzing for risk factors of mortality using multivariate Weibull survival regression stratified by age category. RESULTS Among 9806 individuals who initiated ART, mean age was 37 years (SD: 8.8), average follow-up 5.7 years (SD: 1.7), and median baseline CD4 was 115 cells per cubic millimeter (interquartile range: 42-184). Adults younger than 50 years had on average a higher CD4 increase of 45 cells per cubic millimeter (95% confidence interval: 17 to 72; P = 0.001) compared with counterparts aged 60 years and older. Mortality was highest among older adults compared with younger counterparts. Only CD4 count <100 cells per cubic millimeter after 1 year on ART and a CD4 count less than baseline were associated with a statistically significant higher rate of death among older adults. CONCLUSIONS Older adults had a slower immunological response, which was associated with mortality, but this mortality was not typically associated with opportunistic infections. Future steps would require more evaluation of possible causes of death among these older individuals if survival on ART is to be further improved.

Abstract
Increased life expectancy due to improved efficacy of cART has uncovered an increased risk of age-related morbidities in HIV+ individuals and catalyzed significant research into mechanisms driving these diseases. HIV infection increases the risk of non-communicable diseases common in the aged, including cardiovascular disease, neurocognitive decline, non-AIDS malignancies, osteoporosis, and frailty. These observations suggest that HIV accelerates immunological ageing, and there are many immunological similarities with the aged, including shortened telomeres, accumulation of senescent T cells and altered monocyte phenotype/function. However, the most critical similarity between HIV+ individuals and the elderly, which most likely underpins the heightened risk of non-communicable diseases, is chronic inflammation and associated immune activation. Here, we review the similarities between HIV+ individuals and the aged regarding the pathogenesis of inflammatory diseases, the current evidence for mechanisms driving these processes and discuss current and potential therapeutic strategies for addressing inflammatory co-morbidity in HIV+ infection.

Abstract
PURPOSE OF REVIEW To summarize recent findings on the relationship between CD4 cell count metrics and selected serious clinical outcomes, and to deduce implications for CD4 cell count monitoring in treated HIV infection and the timing of combination antiretroviral therapy initiation. RECENT FINDINGS In treated HIV infection, a higher latest CD4 cell count is associated with a lower short-term risk of serious non-AIDS events (often composite endpoints) even in CD4 cell count strata more than 350/μl. Knowledge of alternate CD4 cell count metrics, such as CD4 cell count slope, nadir level and time spent under specific CD4 cell count thresholds, does not seem to confer additional prognostic information beyond that achieved by current CD4 cell count. Latest CD4 cell count is strongly associated with a short-term risk of infection-related non-AIDS malignancies, and serious hepatic events; however, the evidence is inconsistent for cardiovascular outcomes. Studies vary significantly in definitions of composite endpoints as well as the rigorousness of outcome ascertainment, which could explain the heterogeneity in results. SUMMARY Current CD4 cell count, but not other metrics, could be an important clinical tool to predict the short-term risk of serious non-AIDS events in treated HIV-positive individuals. An earlier initiation of therapy at CD4 cell count more than 350/μl or above 500/μl is likely to improve long-term CD4 cell count metrics. Whether it provides net individual clinical benefit requires a randomized trial.

Abstract
Background. Little is known about survival and factors associated with mortality after cancer diagnosis among persons infected with human immunodeficiency virus (HIV). Methods. Using Poisson regression, we analyzed incidence rates of acquired immune deficiency syndrome (AIDS)-defining cancers (ADC), non-AIDS-defining infection-related cancers (NADCI), and non-AIDS-defining noninfection-related cancers (NADCNI) among HIV Outpatient Study participants seen at least twice from 1996–2010. All-cause mortality within each cancer category and by calendar period (1996–2000, 2001–2005, 2006–2010) were examined using Kaplan-Meier survival methods and log-rank tests. We identified risk factors for all-cause mortality using multivariable Cox proportional hazard models. Results. Among 8350 patients, 627 were diagnosed with 664 cancers. Over the 3 time periods, the age- and sex-adjusted incidence rates for ADC and NADCNI declined (both P < .001) and for NADCI did not change (P = .13). Five-year survival differed by cancer category (ADC, 54.5%; NADCI, 65.8%; NADCNI, 65.9%; P = .018), as did median CD4 cell count (107, 241, and 420 cells/mm3; P < .001) and median log10 viral load (4.1, 2.3, and 2.0 copies/mL; P < .001) at cancer diagnosis, respectively. Factors independently associated with increased mortality for ADC were lower nadir CD4 cell count (hazard ratio [HR] = 3.02; 95% confidence interval [CI], 1.39–6.59) and detectable viral load (≥400 copies/mL; HR = 1.72 [95% CI, 1.01–2.94]) and for NADCNI, age (HR = 1.50 [95% CI, 1.16–1.94]), non-Hispanic black race (HR = 1.92 [95% CI, 1.15–3.24]), lower nadir CD4 cell count (HR = 1.77 [95% CI, 1.07–2.94]), detectable viral load (HR = 1.96 [95% CI, 1.18–3.24]), and current or prior tobacco use (HR = 3.18 [95% CI, 1.77–5.74]). Conclusions. Since 1996, ADC and NADCNI incidence rates have declined. Survival after cancer diagnosis has increased with concomitant increases in CD4 cell count in recent years. Advances in HIV therapy, including early initiation of combination antiretroviral therapy, may help reduce mortality risk among HIV-infected persons with cancer.

Abstract
With the advent of effective combination antiretroviral therapy, HIV infection has been transformed from a fatal disease to a chronic condition. There is renewed clinical interest in long-term morbidities, including malignancies that occur disproportionately within this population. Non-AIDS-defining cancers (NADCs) are a significant source of morbidity and mortality in the aging HIV-infected population. There are data to suggest that incidence rates are elevated among HIV-infected individuals for many cancer sites, particularly those with a confirmed or suspected infectious etiology. The complex interplay between behavioral risk factors, coexistence of viral infections, immunodeficiency and antiretroviral therapy makes it difficult to analyze why certain cancers develop more frequently in HIV-infected individuals. The challenge to clinicians caring for HIV-infected patients is to develop and implement effective means to screen, treat, and prevent NADCs in the future. This review presents data on whether NADCs are increased in the HIV-Infected population, as well as ongoing research on epidemiology, prevention and pathogenesis of this evolving aspect of the HIV epidemic.

Abstract
PURPOSE OF REVIEW In this review, we explore current questions regarding risk factors contributing to frequent and early onset of lung cancer among populations with HIV infection, treatment, and outcomes of lung cancer in HIV-infected patients as well as challenges in a newly evolving era of lung cancer screening. RECENT FINDINGS Lung cancer, seen in three-fold excess in HIV-infected populations, has become the most common non-AIDS defining malignancy in the highly active antiretroviral therapy era. HIV-associated lung cancer appears to be associated with young age at diagnosis, cigarette smoking, advanced stage at presentation, and a more aggressive clinical course. There is no unified explanation for these observations, and aside from traditional risk factors, HIV-related immunosuppression and biological differences might play a role. In addition to smoking cessation interventions, screening and early cancer detection in HIV-infected populations are of high clinical importance, although evidence supporting lung cancer screening in this particularly high-risk subset is currently lacking, as are prospective studies of lung cancer therapy. SUMMARY There is an urgent need for prospective clinical trials in HIV-associated lung cancer to improve understanding of lung cancer pathogenesis and to optimize patient care. Several clinical trials are in progress to address questions in cancer biology, screening, and treatment for this significant cause of mortality in persons with HIV infection.

Abstract
Natural killer (NK) cell function is regulated by a balance between the triggering of activating and inhibitory receptors expressed on their surface. A relevant effort has been focused so far on the study of KIR carriage/expression setting the basis for NK cell education and self-tolerance. Focus on the evolution and regulation of activating NK receptors has lagged behind so far. Our understanding of activating receptor expression and regulation has recently improved by evidences derived from in vitro and in vivo studies. Virus infection - either acute or chronic - determines preferential expansion of NK cells with specific phenotype, activating receptors, and with recall-like functional activity. Studies on patients with viral infection (HIV and HCV) and specific diverging clinical courses confirm that inter-individual differences may exist in baseline expression of natural cytotoxicity receptors (NKp46 and NKp30). The findings that patients with divergent clinical courses have different kinetics of activating receptor density expression upon NK cell activation in vitro provide an additional, time-dependent, functional parameter. Kinetic changes in receptor expression thus represent an additional parameter to basal receptor density expression. Different expression and inducibilities of activating receptors on NK cells contribute to the high diversity of NK cell populations and may help our understanding of the inter-individual differences in innate responses that underlie divergent disease courses.

Abstract
In the highly active antiretroviral therapy (HAART) era, the incidence of non-AIDS-defining cancers (NADC) has increased and contributes to a growing proportion of mortality in the aging HIV-infected population. The underlying pathogenic mechanisms of increased cancer risk are incompletely understood. Potential contributors include oncogenic effects of the HIV virus, immunosuppression, chronic inflammation and immune activation, exposure to HAART, higher rates of oncogenic viral coinfections and traditional cancer risk factors. HIV-infected patients often present with NADC at younger ages with more aggressive or advanced stage disease. However, when standard cancer therapy is given, treatment outcomes appear similar to the non-HIV population. These facts highlight the importance of clinicians' maintaining a high index of suspicion, performing age-appropriate screening, and optimizing cancer therapy. Development of novel strategies for screening, prevention, and treatment of NADC will be required to reverse these epidemiologic trends and improve the survival of HIV-infected patients.

Abstract
HIV-infected patients are at increased risk for developing HIV-related Hodgkin lymphoma (HIV-HL) despite the success of combination antiretroviral therapy (cART). To study the incidence of HIV-HL in HIV-patients with respect to the general population of Brescia, Italy, we conducted a single-center cohort study of HIV-patients followed from 1999 to 2009. The incidence of HIV-HL was compared to the incidence in the general population of Brescia using standardized incidence ratios (SIRs). Poisson analysis was used to study the association between covariates and HL. A total of 5085 HIV-patients were observed among 30,946 person-years; 30 patients developed HIV-HL. The incidence rate was 9.9 (95% confidence interval [CI], 6.7-14.1) per 10,000 person-years of follow-up. HL was substantially more frequent in HIV-patients than in the general population living in the same district area [standardized incidence rate, SIR=21.8 (95% CI, 15.33-31)]. The risk of HIV-HL tended to increase with lowering CD4+ cell counts at time of HL diagnosis [adjusted incidence relative risk (IRR) for CD4 cell count<50 cells/μL: 41.70, p<0.001]. HL risk had been elevated during the 6 months after combination antiretroviral therapy (cART) initiation (IRR: 26.65, p<0.001). Twenty-two HIV-HL cases were matched to 3280 controls. In the year preceding HIV-HL diagnosis the mean change in CD4+ cell counts between cases and controls was significantly different (-99 cells/μL for cases vs. +37 cells/μL for controls, p<0.0001). Compared with the general population, HIV-infected patients showed an increased risk for developing HL. The risk of HIV-HL increased significantly in the first months after cART initiation.

Abstract
OBJECTIVES The aim of the study was to investigate the incidence of AIDS-defining cancers (ADCs) and virus-related and non-virus-related non-AIDS-defining cancers (NADCs) in HIV-infected patients compared with the general population, and to assess the risk factors associated with these malignancies. METHODS We performed a retrospective cohort study for the period from 1999 to 2009 of HIV-infected patients residing in the Local Health Authority of Brescia (northern Italy). Observed cancers in patients with HIV infection were compared with expected cancers in the population living in the same area using standardized incidence ratios (SIRs). Risk factors were assessed using Poisson regression analysis. RESULTS A total of 5090 HIV-infected patients were included in the study, with 32 390 person-years of follow-up. We recorded 416 tumours in 390 HIV-infected patients. Two hundred of these (48.1%) were ADCs, 138 (33.2%) were non-virus-related NADCs and 78 (18.7%) were virus-related NADCs. An increased risk (SIR = 4.2) of cancers overall was found in HIV-infected patients. A large excess of ADCs (SIR = 31.0) and virus-related NADCs (SIR = 12.3) was observed in HIV-infected patients, while the excess risk for non-virus-related NADCs was small (SIR = 1.6). The highest SIRs were observed for Kaposi sarcoma among ADCs and for Hodgkin lymphoma among virus-related NADCs. Conversely, among non-virus-related NADCs, SIRs for a broad range of malignancies were close to unity. In multivariate analysis, increasing age and CD4 cell count < 50 cells/μL were the only factors independently associated with all cancers. CONCLUSIONS Among HIV-infected people there was an excess of ADCs and also of NADCs, particularly those related to viral infections. Ageing and severe immunodeficiency were the strongest predictors.

Risk of clinical progression among patients with immunological nonresponse despite virological suppression after combination antiretroviral treatment. AIDS 2013; 27:769-79.

Abstract
BACKGROUND It is unclear whether lack of immunological response despite viral suppression and relatively preserved CD4 T-cell count is associated with increased risk of AIDS or severe non-AIDS events. METHODS Patients initiating first combination antiretroviral therapy (cART) were studied from first viral load 80 copies/ml or less up to AIDS, serious non-AIDS events (malignancies, severe infections, acute kidney injury, cardiovascular events, liver decompensation) or death. Follow-up was right censored if viral load was more than 500. Immunological nonresponse (INR) was defined as current CD4 cell count less than 120% pre-cART. A Poisson regression analysis was used to investigate the association between INR and the outcome. RESULTS Three thousand, three hundred and seventy-eight patients were followed for a median of 32 months (interquartile range: 15-67). Two hundred and twenty-two events (32 deaths, 39 AIDS-defining events, 48 malignancies, 32 severe infections, 47 acute kidney injuries, 12 cardiovascular events, 12 other nonfatal events) were observed. The rate of clinical events among INR and immunological responders was 4.41 [95% confidence interval (CI) 3.38-5.74] and 1.84 (95% CI 1.58-2.15) per 100 person years of follow-up, respectively, accounting for a crude rate ratio of 2.39 (95% CI 1.77-3.25; P < 0.001). INR remained an independent predictor of clinical progression after adjusting for baseline characteristics, including pre-cART CD4 cell count (adjusted rate ratio 2.93; 95% CI 2.06-4.16, P < 0.001) or current CD4 cell count (adjusted rate ratio 1.94; 95% CI 1.39-2.72, P < 0.001). The association did not vary by pre-cART CD4 cell counts (P for interaction = 0.93) CONCLUSION INR are at higher risk of severe clinical events than responders. The association was consistent across different CD4 cell counts at cART initiation and was only partially explained by current CD4 cell count. INR could be a marker of immune system malfunctioning, not completely captured by absolute CD4 cell count.

Abstract
OBJECTIVE The incidence of certain non-AIDS-defining cancers (NADCs) in HIV patients has been reported to have increased in the combination antiretroviral therapy (ART) era. Studies are needed to directly evaluate the effect of ART use on cancer risk. DESIGN We followed 12 872 HIV-infected Kaiser Permanente members whose complete ART history was known for incident cancers between 1996 and 2008. METHODS Cancers, identified from Surveillance, Epidemiology, and End Results (SEER)-based cancer registries, were grouped as ADCs, infection-related NADCs, or infection-unrelated NADCs. We also evaluated the most common individual cancer types. Rate ratios for ART use (yes/no) and cumulative duration of any ART, protease inhibitor, and nonnucleotide reverse transcriptase inhibitor (NNRTI) therapy were obtained from Poisson models adjusting for demographics, pretreatment or recent CD4 cell count and HIV RNA levels, years known HIV-infected, prior antiretroviral use, HIV risk, smoking, alcohol/drug abuse, overweight/obesity, and calendar year. RESULTS The cohort experienced 32 368 person-years of ART, 21 249 person-years of protease inhibitor therapy, and 15 643 person-years of NNRTI therapy. The mean follow-up duration was 4.5 years. ADC rates decrease with increased duration of ART use [rate ratio per year = 0.61 (95% confidence interval 0.56-0.66)]; the effect was similar by therapy class. ART, protease inhibitor, or NNRTI therapy duration was not associated with infection-related or infection-unrelated NADC [rate ratio per year ART = 1.00 (0.91-1.11) and 0.96 (0.90-1.01), respectively], except a higher anal cancer risk with longer protease inhibitor therapy [rate ratio per year = 1.16 (1.02-1.31)]. CONCLUSION No therapy class-specific effect was found for ADC. ART exposure was generally not associated with NADC risk, except for long-term use of protease inhibitor, which might be associated with increased anal cancer risk.

Abstract
PURPOSE OF REVIEW Combination antiretroviral therapy (ART) has turned HIV infection into a complex chronic disease. This article documents cancer risk among HIV-infected persons, reviews immune system effects of HIV infection in relation to cancer risk, discusses implications for cancer prevention, and suggests future research directions. RECENT FINDINGS There has been a shift in the cancer spectrum from AIDS-defining cancers (ADC) to non-ADC, although the burden of ADC remains high. Although a high prevalence of non-HIV cancer risk factors among HIV-infected persons contributes to cancer risk, substantial evidence has accumulated in favor of an independent association between HIV-induced immunodeficiency and elevated risk of many specific cancer types, most of viral cause, although further work is needed to disentangle immunodeficiency and smoking effects for lung cancer, and immunodeficiency and hepatitis virus effects for liver cancer. Relationships between cancer risk and two other immune system hallmarks of HIV infection, chronic inflammation, and immune dysfunction/senescence, remain poorly understood. SUMMARY Early, sustained ART is a crucial component of cancer prevention. Continued epidemiologic monitoring is needed to detect possible effects on cancer risk of specific ART classes or medications, long-term exposure to systemic inflammation or immune dysfunction, or earlier or more effective ART.

Abstract
A novel dynamic model covering five types of cells and three connected compartments, peripheral blood (PB), lymph nodes (LNs), and the central nervous system (CNS), is here proposed. It is based on assessment of the biological principles underlying the interactions between the human immunodeficiency virus type I (HIV-1) and the human immune system. The simulated results of this model matched the three well-documented phases of HIV-1 infection very closely and successfully described the three stages of LN destruction that occur during HIV-1 infection. The model also showed that LNs are the major location of viral replication, creating a pool of latently infected T4 cells during the latency period. A detailed discussion of the role of monocytes/macrophages is made, and the results indicated that infected monocytes/macrophages could determine the progression of HIV-1 infection. The effects of typical highly active antiretroviral therapy (HAART) drugs on HIV-1 infection were analyzed and the results showed that efficiency of each drug but not the time of the treatment start contributed to the change of the turnover of the disease greatly. An incremental count of latently infected T4 cells was made under therapeutic simulation, and patients were found to fail to respond to HAART therapy in the presence of certain stimuli, such as opportunistic infections. In general, the dynamics of the model qualitatively matched clinical observations very closely, indicating that the model may have benefits in evaluating the efficacy of different drug therapy regimens and in the discovery of new monitoring markers and therapeutic schemes for the treatment of HIV-1 infection.

Role of serum free light chains in predicting HIV-associated non-Hodgkin lymphoma and Hodgkin's lymphoma and its correlation with antiretroviral therapy. Am J Hematol 2012; 87:749-53.

Abstract
A nested case-control study was performed within the Italian cohort of naïve to antiretroviral human immunodeficiency virus (HIV) patients (ICONA) cohort to evaluate the role of serum free light chains (sFLC) in predicting non-Hodgkin's lymphoma (NHL) and Hodgkin lymphoma (HL) in HIV-infected individuals. Of 6513 participants, 86 patients developed lymphoma and 46 of these (NHL, 30; HL, 16) were included in this analysis having stored prediagnostic blood. A total of 46 serum case samples matched 1:1 to lymphoma-free serum control samples were assayed for κ and λ sFLC levels and compared by using conditional logistic regression. Because the polyclonal nature of free light chains (FLCs) was the focus of our study, we introduced the k + λ sum as the measurement of choice and as the primary variable studied. κ + λ sFLC values were significantly higher in patient with lymphoma than in controls, especially when considering samples stored 0-2-year period before the lymphoma diagnosis. In the multivariable analysis, the elevation of sFLC predicted the risk of lymphoma independently of CD4 count, (odd ratio of 16.85 for k + λ sFLC >2-fold upper normal limit (UNL) vs. normal value). A significant reduction in the risk of lymphoma (odd ratio of 0.07 in model with k + λ sFLC) was found in people with low sFLC and undetectable HIV viremia lasting more than 6 months. Our analysis indicates that an elevated polyclonal sFLC is a strong and sensitive predictor of the risk of developing lymphomas, and it is an easy to measure biomarker that merits consideration for introduction in routine clinical practice in people with HIV.

Abstract
BACKGROUND To study the prevalence, predictors and outcome of late HIV diagnosis in the Icona cohort, according to the new European consensus definition of late diagnosis. METHODS In this observational cohort study we investigated patients diagnosed with HIV over 3 months preceding enrolment who were defined as diagnosed late if they presented with AIDS or a CD4(+) T-cell count ≤ 350/mm³ (European consensus definition). We estimated the prevalence of late diagnosis, identified factors associated with being diagnosed late and looked at the prognostic value of the European consensus definition of late presentation to predict subsequent clinical progression (new AIDS events or death). RESULTS In total, 1,438/2,276 patients (63%) were defined as diagnosed late using the new European Consensus definition. Of these, 387 (16%) were AIDS-presenters. Predictors of being diagnosed late were older age, non-Italian origin, high HIV RNA and unemployment (versus retirement). A total of 293 patients showed clinical progression (3 events/100 person-years of follow-up, 95% CI: 2.7-3.4). Presenting late was strongly associated with a >5-fold increased risk of disease progression. CONCLUSIONS In our observational setting with free access to care, more than 60% of new HIV diagnoses occurred below the recommended threshold for initiating antiretroviral treatment. Presenting late for care was associated with a high risk of clinical progression.

Abstract
OBJECTIVE We investigated the risk of AIDS and serious non-AIDS-defining diseases (non-ADDs) according to the degree of immunological recovery after 2 years of virological successful antiretroviral therapy (HAART). DESIGN Retrospective observational cohort study including HIV-infected patients treated with HAART resulting in viral suppression (<500 copies/ml). METHODS Patients were grouped according to their CD4 cell count after 2 years of HAART: CD4 cell count less than 200 cells/μl (group A), 200-350 cells/μl (group B), 351-500 cells/μl (group C) or more than 500 cells/μl (group D). Analysis was done to assess predictors for poor immunological recovery and the occurrence of a composite endpoint [death, AIDS, malignancies, liver cirrhosis and cardiovascular events (CVEs)], non-ADDs, CVEs and non-AIDS-defining malignancies (non-ADMs). RESULTS Three thousand and sixty-eight patients were included. Older age, lower CD4 cell nadir and lower plasma HIV-RNA at the start of HAART were independent predictors for a poor immunological recovery. The composite endpoint, non-ADDs and CVE were observed most frequently in group A (overall log rank, P < 0.0001, P = 0.002 and P = 0.01). In adjusted analyses, age was a strong independent predictor for all endpoints. Compared with group A, patients in group D had a lower risk for the composite endpoint [hazard ratio 0.54 (95% confidence interval [CI] 0.33-0.87]; patients in group B had a lower risk for CVEs [hazard ratio 0.34 (95% CI 0.14-0.86)]. CONCLUSION Poor immunological recovery despite virological successful HAART is associated with a higher risk for overall morbidity and mortality and CVEs in particular. This study underlines the importance of starting HAART at higher CD4 cell counts, particularly in older patients.

Abstract
'Test and treat' is a strategy in which widespread screening for human immunodeficiency virus (HIV) is followed by immediate antiretroviral therapy for those testing positive, thereby potentially reducing infectiousness in larger cohorts of infected patients. However, there is a concern that test and treat could lead to increased the levels of transmissible drug-resistant HIV, especially if viral load and/or drug resistance is not routinely monitored. Reviews of the existing literature show that up to now, even in the absence of laboratory tests, drug resistance has not created major problems in sub-Saharan Africa. Here, we discuss the current evidence for the effectiveness of a preventive test and treat approach and the challenges and implications for daily clinical practice and public health.

Abstract
BACKGROUND Few studies have compared cancer risk between HIV-infected individuals and a demographically similar HIV-uninfected internal comparison group, adjusting for cancer risk factors. METHODS We followed 20,775 HIV-infected and 215,158 HIV-uninfected individuals enrolled in Kaiser Permanente (KP) California for incident cancer from 1996 to 2008. Rate ratios (RR) were obtained from Poisson models comparing HIV-infected (overall and stratified by recent CD4 count and HIV RNA) with HIV-uninfected individuals, adjusted for age, sex, race/ethnicity, calendar period, KP region, smoking, alcohol/drug abuse, and overweight/obesity. RESULTS We observed elevated RRs for Kaposi sarcoma (KS; RR = 199; P < 0.001), non-Hodgkin lymphoma (NHL; RR = 15; P < 0.001), anal cancer (RR = 55; P < 0.001), Hodgkin lymphoma (HL; RR = 19; P < 0.001), melanoma (RR = 1.8; P = 0.001), and liver cancer (RR = 1.8; P = 0.013), a reduced RR for prostate cancer (RR = 0.8; P = 0.012), and no increased risk for oral cavity/pharynx (RR = 1.4; P = 0.14), lung (RR = 1.2; P = 0.15), or colorectal (RR = 0.9; P = 0.34) cancers. Lung and oral cavity/pharynx cancers were elevated for HIV-infected subjects in models adjusted only for demographics. KS, NHL, anal cancer, HL, and colorectal cancer had significant (P < 0.05) trends for increasing RRs with decreasing recent CD4. The RRs for lung and oral cavity/pharynx cancer were significantly elevated with CD4 < 200 cells/μL and for melanoma and liver cancer with CD4 < 500 cells/μL. Only KS and NHL were associated with HIV RNA. CONCLUSION Immunodeficiency was positively associated with all cancers examined except prostate cancer among HIV-infected compared with HIV-uninfected individuals, after adjustment for several cancer risk factors. IMPACT Earlier antiretroviral therapy initiation to maintain high CD4 levels might reduce the burden of cancer in this population.

Abstract
BACKGROUND Lung cancer is the leading cause of death among non-acquired immunodeficiency syndrome (AIDS)-defining malignancies. Because highly active antiretroviral therapy (HAART) has improved the survival of patients with human immunodeficiency virus (HIV), the authors evaluated lung cancer outcomes in the HAART era. METHODS HIV-positive patients who were diagnosed with lung cancer at the authors' institution during the HAART era (1995-2008) were analyzed. Patient charts were reviewed for clinical and laboratory data. The CD4 count at diagnosis was treated as a continuous variable and subcategorized into distinct variables with 3 cutoff points (50 cells/mL, 200 cells/mL, and 500 cells/mL). Pearson correlation coefficients were estimated for each covariate studied. Survival was determined by using the Kaplan-Meier method. RESULTS Of 80 patients, 73 had nonsmall cell lung cancer. Baseline characteristics were as follows: median patient age, 52 years; male, 80%; African Americans, 84%; injection drug users, 25%; smokers, 100%; and previous exposure to antiretroviral agents, 55%. At the time of cancer diagnosis, the mean CD4 count was 304 cells/mL, and the mean viral load was 82,420 copies/mL. The latency between HIV diagnosis and lung cancer diagnosis was significantly shorter among women (4.1 years vs 7.7 years; P = .02), and 71% of patients received anticancer therapy. The 1-year and 3-year survival rates for stage IIIB/IV were 25% and 0%, respectively. Grade 3/4 toxicities occurred in 60% of patients who received chemoradiation versus 36% of patients who received chemotherapy. Cancer-related survival was better for patients with CD4 counts >200 cells/mL (P = .0298) and >500 cells/mL (P = .0076). CONCLUSIONS The latency from diagnosis of HIV to lung cancer was significantly shorter for women. Although outcomes for patients with lung cancer who have HIV remain poor, a high CD4 count was associated with improved lung cancer-related survival.

Abstract
BACKGROUND Prospective data on factors associated with the non-AIDS-defining cancer (NADC) incidence in HIV-infected individuals are limited. METHODS We examined the NADC incidence in 3,158 antiretroviral treatment (ART)-naïve subjects after ART initiation in AIDS Clinical Trials Group trials; extended follow-up was available for 2,122 subjects. Poisson regression was used to examine the associations between covariates and incident NADC. RESULTS At ART initiation, subjects (median age 37 years) were 40% non-Hispanic whites, and 82% were male; 23% had CD4+ T cell count ≤ 50 cells/mm³ and 25% had CD4 >350 cells/mm³. Median follow-up was 3.8 years. Among 64 incident NADCs, the most common were 8 anal cancers, 8 basal cell carcinomas, 8 Hodgkin's disease, and 6 lung cancers. In univariate models, age, smoking and recent (time-updated) CD4 were associated with incident NADC. There was no association between initial ART drug class (protease inhibitor, nucleoside reverse transcriptase inhibitor and nonnucleoside reverse transcriptase inhibitor) and NADC. After adjusting for age, race and sex: smoking [relative risk = 2.12 (95% CI = 1.1-4.08)] and recent CD4 (≤ 50 cells/mm³: 3.58, 1.22-10.45; 51-200 cells/mm³: 2.54, 1.30-5.0; 201-350 cells/mm³: 2.37, 1.32-4.26 vs. >350 cells/mm³) were associated with NADC. CONCLUSION Smoking and lower recent CD4 levels, but not initial ART drug class, were associated with NADC. Strategies for maintaining higher CD4 cell counts and successful smoking cessation may reduce the NADC incidence in the HIV-infected population.

Abstract
Malignancies account for more than a third of all deaths in human immunodeficiency virus (HIV)-positive patients. Although acquired immunodeficiency syndrome-related mortality is decreasing with the introduction of effective antiretroviral therapy, the incidence of lung cancer in patients with HIV remains high. Lung cancer has now become the leading cause of mortality among the nonacquired immunodeficiency syndrome defining malignancies. Within the HIV population, the incidence of lung cancer is estimated to be approximately 2 to 4 times that of the general population. Often these patients present with advanced disease (stage III or IV) at a younger age and have an inferior overall survival, when compared with non-HIV patients. Development of lung cancer in patients with HIV has been linked to various factors including immunosuppression, CD4 count, viral load, and smoking. This article reviews the impact of HIV on the incidence, risk factors, clinical presentation, and treatment of lung cancer.

Abstract
Background Data regarding CD4+ recovery after switching from protease inhibitor (PI)-based regimens to regimens not containing PI are scarce. Methods Subjects with virological success on first-PI-regimens who switched to NNRTI therapy (NNRTI group) or to nucleoside reverse transcriptase (NRTI)-only (NRTI group) were studied. The effect of the switch on the ongoing CD4+ trend was assessed by two-phase linear regression (TPLR), allowing us to evaluate whether a change in the CD4+ trend (hinge) occurred and the time of its occurrence. Furthermore, we described the evolution of the frequencies in CD4-count classes across four relevant time-points (baseline, before and immediately after the switch, and last visit). Finally, we explored whether the CD4+ counts evolved differently in patients who switched to NNRTI or NRTI-only regimens by considering: the overall CD4+ trends, the time to CD4+≥ 500/mm3 after the switch, and the area-under-the-curve (AUC) of the CD4+ after the switch. Results Eight hundred and ninety-six patients, followed for a median of 2,121 days, were included. At TPLR, hinges occurred in 581/844 (68.9%), but in only 40/581 (6.9%) within a time interval (180 days) compatible with a possible relationship to the switch; furthermore, in 19/40 cases, CD4+ counts appeared to decrease after the hinges. In comparison with the NNRTI group, the NRTI group showed CD4+ count greater at baseline (P = 0.0234) and before the switch (P ≤ 0.0001), superior CD4+ T-cell increases after HAART was started, lower probability of not achieving CD4+ ≥ 500/mm3 (P = 0.0024), and, finally, no significant differences in the CD4+ T-cell AUC after the switch after adjusting for possible confounders (propensity score and pre-switch AUC). Persistence at CD4+ < 200/mm3 was observed in 34/435 (7.5%) patients, and a decrease below this level was found in only 10/259 (3.9%) with baseline CD4+ ≥ 350/mm3. Conclusions Switching from first-line PI to NNRTI- or NRTI-based regimens did not seem to impair CD4+ trend over long-term follow-up. Although the greater CD4+ increases in patients who switched to the NRTI-only regimen was due to higher CD4+ counts before the switch, several statistical analyses consistently showed that switching to this regimen did not damage the ongoing immune-reconstitution. Lastly, the observation that CD4+ T-cell counts remained low or decreased in the long term despite virological success merits further investigation.

Abstract
OBJECTIVE We aimed to examine the clinical outcome in HIV-1-infected patients after more than 10 years of highly active antiretroviral therapy (HAART). METHODS We analyzed data from 1,236 treatment-naïve adults who had started HAART. The primary endpoint was the yearly prevalence of death for AIDS-related causes (ARC) or for non-AIDS related causes (non-ARC). The data from our cohort were compared with that of the general population (GP) of our region. RESULTS We observed that 116 patients died, and 58.6% of deaths were non-ARC. The death incidence decreased from 18.8% in 1998-1999 to 1.2% in 2008-2009. The leading causes of death were malignancies (35.3%), infections (21.6%), end-stage liver diseases (18.1%), and cardiovascular diseases (CVD) (6.9%). Yearly death rates were similar in the HIV-infected cohort and in the crude GP (odds ratio [OR] 1.1, 95% confidence interval [CI] 0.5-2.5), but when adjusted for age, HIV-infected patients showed a greater risk (OR 7.4, 95% CI 4.1-13.4). The difference was still highly significant when the analysis was restricted to non-ARCs (OR 4.3, 95% CI 2.07-9.2). Overall, malignancies (OR 5.7, 95% CI 2.6-12.8) and end-stage liver diseases (OR 35.0, 95% CI 15.5-78.8) were significantly more frequent than in the age-adjusted GP. CONCLUSIONS Despite HAART, HIV-infected patients are at greater risk of death compared to a reference uninfected population.
