Abstract
After a decade of dolutegravir (DTG) use in various antiretroviral therapy combinations and in diverse populations globally, it is critical to identify HIV strains with reduced drug susceptibility and monitor emergent resistance in people living with HIV who experience virologic failure while on DTG-based regimens. We searched the PubMed, Embase, and Cochrane databases to identify studies that reported DTG resistance-associated mutations (RAMs) emerging under selection pressure. Our review showed that RAMs conferring resistance to DTG were rare in 2-drug and 3-drug regimens used in real-world cohorts, corroborating data from clinical trials. The potency of DTG in maintaining virologic suppression was demonstrated, even in cases of pre-existing resistance to companion drugs in the regimen. Estimates of DTG RAMs depended on the population and certain risk factors, including monotherapy, baseline resistance or lack of genotypic testing, treatment history and prior virologic failure, and suboptimal treatment adherence. The RAMs detected after virologic failure, often in heavily treatment-experienced individuals with prior exposure to integrase strand transfer inhibitors, were G118R, E138K, G140A/C/R/S, Q148H/K/R, N155H, and R263K. Overall, these data highlight the durable effectiveness and high barrier to resistance of DTG as part of combination antiretroviral therapy in a wide variety of settings.

Abstract
Background HIV management among older people living with HIV (PLWH) may be complicated by the presence of multiple comorbidities and polypharmacy. This study evaluated effectiveness and durability of modern 3-drug antiretroviral regimens among older PLWH. Methods Using data from the Veterans Aging Cohort Study (VACS), PLWH ≥50 years old initiating a dolutegravir (DTG), bictegravir (BIC), elvitegravir (EVG), raltegravir (RAL), or darunavir (DRV)-based 3-drug regimen for the first time between January 1, 2014, and March 31, 2020 were followed from regimen initiation (baseline) until regimen discontinuation (d/c), death, loss to follow-up, or end of study (September 30, 2020). Suppression [viral load (VL)< 50 copies/mL], change in CD4 cell count, and regimen d/c were compared between regimens 6- and 12-months post-baseline using multivariable logistic or linear regression. Virologic failure (VF; 2 consecutive VLs ≥ 200 copies/ml, or 1VL ≥ 200 copies/ml followed by regimen d/c) was evaluated over 12 months. For all outcomes, DTG-based regimens were compared to each other regimen. Outcomes were stratified by treatment experience (ART-naïve and ART-experienced). Results 2,489 ART-naive (DTG: 912, BIC: 432, EVG: 751, RAL: 159, DRV: 235) and 13,810 ART-experienced (DTG: 5097, BIC: 1765, EVG: 3582, RAL: 1486, DRV: 1880) individuals were included. Included PLWH were 97% male and 30% were ≥65 years old (Table 1). For both naive and experienced PLWH, those on DTG were more likely suppressed and had greater increases in CD4 counts at 6 and 12 months compared to those on DRV or RAL (Table 2). Odds of VF did not differ by regimen for ART-naive. For ART-experienced, DTG showed reduced likelihood of VF compared to DRV and RAL. Discontinuations within the first year were higher for RAL and DRV compared to DTG. For ART-experienced PLWH, 6-month d/c was greater for DTG vs. EVG. Regardless of treatment status, no other statistical differences in outcomes were observed between DTG-, BIC-, and EVG-based regimens.
![]() ![]() Conclusion For both ART-naïve and ART-experienced PLWH >50 years old, treatment responses during the first 12 months of follow-up were similar for those taking DTG-, BIC-, and EVG-based regimens. DTG-based regimens demonstrated greater effectiveness and durability compared to DRV- or RAL-based regimens.

Abstract
Abstract
Background
Paired with other active antiretrovirals (ARVs), fostemsavir (FTR) may offer heavily treatment-experienced (HTE) people with HIV (PWH) options for continuing effective treatment. Durability and effectiveness of FTR-containing regimens in routine clinical care in the United States were assessed.
Methods
Electronic health record data from the OPERA® cohort were used to identify adults initiating FTR-containing regimens between 2JUL2020 (FDA approval) and 1SEP2021. Eligible PWH were followed from first FTR prescription (baseline) until FTR discontinuation, death, loss to follow up, or study end (28FEB2022). Durability was assessed as frequency of FTR discontinuation. Virologic outcomes assessed at 6 and 12 months (±3 months) included suppression (viral load [VL] < 50 copies/mL), virologic failure (2 consecutive VL ≥200 copies/mL or 1 VL ≥200 copies/mL + FTR discontinuation within 120 days after suppression), and viral blips (1 VL ≥50 copies/mL preceded and followed by VLs < 50 copies/mL). Analyses were stratified by baseline viral load (bVL < 50 copies/mL; bVL ≥50 copies/mL).
Results
Overall, 86 PWH initiated FTR (bVL < 50: 30; bVL ≥50: 55), with median follow up of 10.8 months (IQR: 6.8, 15.3). Compared to PWH with bVL ≥50, those with bVL < 50 were older and more likely to be white and have lived longer with HIV (Table 1). Over follow up, 20% discontinued FTR (Table 2). Most (82%) FTR discontinuations were switches to alternative regimens; the remaining were ARV interruptions (no ARVs for > 45 days). Among PWH with bVL < 50, most maintained suppression (6 months: 74%; 12 months: 82%; Figure). Among PWH with bVL ≥50 and with follow up VL during the period assessed, 33% were suppressed at 6 months, 36% were suppressed at 12 months, and 48% achieved suppression at any time over the entire follow up (Figure). In either group, ≤5 PWH experienced virologic failure or blip, though the proportion of PWH with multiple follow up VLs was low.
Conclusion
Despite a heterogenous population and diverse regimens, most HTE PWH remained on FTR at study end. Most PWH with bVL < 50 remained suppressed and half of PWH with bVL ≥50 achieved suppression over the entire study period. Virologic failure and blips were infrequent, although follow up was limited in this early evaluation of real-world FTR use.

Abstract
Background Real-world effectiveness of fixed dose dolutegravir/lamivudine (DTG/3TC) two-drug regimens (2DR) during the first 24 months of availability in the US was compared to common three-drug regimens (3DRs) among suppressed antiretroviral therapy (ART)-experienced people living with HIV (PLWH). Methods Suppressed (viral load [VL] < 200 copies/mL) PLWH initiating DTG/3TC 2DR, bictegravir (BIC)-3DR, or DTG-3DR between 01MAY2019 and 31OCT2020 in the OPERA® Cohort were followed until 30APR2021 (potential for ≥6 months of follow-up). Univariate Poisson regression (incidence rates) and Cox proportional hazards marginal structural models were employed to assess confirmed virologic failure (2 viral loads [VLs] ≥200 copies/mL) or regimen discontinuation. Results Overall, 8037 PLWH were included in the analysis (Table). Virologic failure incidence rates were low, ranging from 0.66 (DTG/3TC) to 1.78 (DTG 3DR) per 100 person-years. Compared to DTG/3TC, only DTG 3DR was associated with an increase in the hazard of virologic failure. Discontinuation incidence rates ranged from 8.30 (BIC 3DR) to 24.9 (DTG 3DR) per 100 person-years. The discontinuation hazard was 69% greater with DTG 3DRs and 49% lower with BIC 3DRs compared to DTG/3TC. Regardless of regimen, most discontinuers were suppressed (VL< 200 copies/mL) at the time of discontinuation (DTG/3TC 2DR: 96%, BIC 3DR: 94%, DTG 3DR: 93%; all p >0.05). Discontinuations following an adverse diagnosis/side effect were uncommon with DTG/3TC 2DR (3%) and DTG 3DR (4%, p=0.5), and higher with BIC 3DR discontinuation (7%, p=0.02). The most common reason for DTG 3DR discontinuations was regimen simplification (21%); no reason was given for >50% of the discontinuations in each group.
![]() Conclusion Among ART-experienced, virologically suppressed PLWH, virologic failure was rare after switching to DTG/3TC 2DR, BIC 3DR or DTG 3DR. Most discontinuations were not attributed to the treatment (i.e., loss of suppression, adverse diagnosis, side effects), suggesting other reasons for discontinuation despite high levels of suppression and tolerability.

Abstract
Background The COVID-19 pandemic has disrupted health care services for people living with HIV (PLWH). This study aimed to compare rates of clinical visits, viral load monitoring and antiretroviral therapy (ART) regimen discontinuation among virally suppressed PLWH in the US before and during the COVID pandemic. Methods The study population consisted of ART-experienced PLWH ≥18 years of age and active in care in the OPERA cohort within 2 years prior to 31OCT2020. Virally suppressed PLWH (i.e., viral load < 200 copies/mL) were included if they switched to either dolutegravir/lamivudine or a dolutegravir- or bictegravir-based 3-drug regimen between 01MAY2019 and 30APR2020. The study periods spanned from 01MAY2019 to 28FEB2020 (pre-COVID) and 01MAR2020 to 31OCT2020 (during COVID). Incidence rates of clinical visits, viral load measurements and regimen discontinuation were estimated using univariate Poisson regression for both study periods. In-person visits comprised any scheduled or walk-in outpatient, inpatient, emergency or laboratory visit. Telehealth visits comprised any phone or video encounters. Results The study included 4806 PLWH in the pre-COVID and 4992 in the COVID period. Rates of in-person visits were reduced almost 2-fold during COVID, while telehealth visits increased almost 9-fold, resulting in an overall reduction in any visits rates from 10.07 visits per person-year (95% CI: 9.93, 10.21) pre-COVID to 7.10 (95% CI: 7.01, 7.19) during COVID [Fig 1]. Rates of viral load measurements dropped from 2.99 viral loads per person-year (95% CI: 2.92, 3.07) pre-COVID to 1.97 (95% CI: 1.92, 2.02) during COVID [Fig 2]. Regimen discontinuation rates were also reduced from 14.3 discontinuations per 100 person-years pre-COVID (95% CI: 12.7, 16.1) to 9.6 (95% CI: 8.6, 10.8) during COVID [Fig 3]. In both study periods, virologic failures were detected in < 1% of PLWH with ≥ 1 viral load. Figure 1.

Incidence rates for viral load measurements during the pre-COVID (open circle) and the COVID (filled circle) study periods ![]()

Conclusion The COVID pandemic has led to an important reduction in the frequency and type of clinical follow-up visits and viral load monitoring among virally suppressed PLWH in the US. A reduction in regimen discontinuation rates was also observed, presumably associated to less frequent follow-up. The long-term impact of the pandemic on HIV care remains uncertain.

Abstract
With obesity on the rise among people living with HIV (PLWH), there is growing concern that weight gain may result as an undesired effect of antiretroviral therapy (ART). This analysis sought to assess the association between ART regimens and changes in body mass index (BMI) among ART-experienced, virologically suppressed PLWH. ART-experienced, virologically suppressed PLWH ≥18 years of age in the Observational Pharmacoepidemiology Research and Analysis (OPERA) cohort were included for analysis if prescribed a new regimen containing one of the following core agents: dolutegravir (DTG), elvitegravir/cobicistat (EVG/c), raltegravir (RAL), rilpivirine (RPV), or boosted darunavir (bDRV), for the first time between August 1, 2013 and December 31, 2017. Multivariable linear regression was used to assess the association between regimen and mean changes in BMI at 6, 12, and 24 months after switch. In unadjusted analyses, BMI increases ranged from 0.30 kg/m2 (bDRV) to 0.83 kg/m2 (RPV) at 24 months following switch, but gains were observed with every regimen. In adjusted analyses, compared to DTG, only bDRV was associated with a smaller increase in BMI at all time points, while EVG/c and RAL were associated with smaller increases in BMI at 6 months only. Overall, results were consistent in analyses stratified by baseline BMI category. BMI increases were relatively small but followed an upward trend over time in this cohort of treatment-experienced, suppressed PLWH. Gains were attenuated with a longer period of follow-up. BMI gains did not differ by regimens, except for bDRV regimens, which were consistently associated with smaller BMI increases than DTG.

Abstract
OBJECTIVES Evaluate differences in weight change by regimen among people living with HIV (PLWH) initiating antiretroviral therapy (ART) in the current era. METHODS Between 2012 and 2019, 3232 ART-naïve PLWH initiated ≥3-drug ART regimens in 8 Centers for AIDS Research Network of Integrated Clinical Systems sites. We estimated weight change by regimen for 11 regimens in the immediate (first 6 months) and extended (all follow-up on initial regimen) periods using linear mixed models adjusted for time on regimen, interaction between time and regimen, age, sex, race/ethnicity, hepatitis B/C coinfection, nadir CD4, smoking, diabetes, antipsychotic medication, and site. We included more recently approved regimens [eg, with tenofovir alafenamide fumarate (TAF)] only in the immediate period analyses to ensure comparable follow-up time. RESULTS Mean follow-up was 1.9 years on initial ART regimen. In comparison to efavirenz/tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC), initiating bictegravir/TAF/FTC {3.9 kg [95% confidence interval (CI): 2.2 to 5.5]} and dolutegravir/TAF/FTC [4.4 kg (95% CI: 2.1 to 6.6)] were associated with the greatest weight gain in the immediate period, followed by darunavir/TDF/FTC [3.7 kg (95% CI: 2.1 to 5.2)] and dolutegravir/TDF/FTC [2.6 kg (95% CI: 1.3 to 3.9)]. In the extended period, compared with efavirenz/TDF/FTC, initiating darunavir/TDF/FTC was associated with a 1.0 kg (95% CI: 0.5 to 1.5) per 6-months greater weight gain, whereas dolutegravir/abacavir/FTC was associated with a 0.6-kg (95% CI: 0.3 to 0.9) and dolutegravir/TDF/FTC was associated with a 0.6-kg (95% CI: 0.1 to 1.1) per 6-months greater gain. Weight gain on dolutegravir/abacavir/FTC and darunavir/TDF/FTC was significantly greater than that for several integrase inhibitor-based regimens. CONCLUSIONS There is heterogeneity between regimens in weight gain following ART initiation among previously ART-naïve PLWH; we observed greater gain among PLWH taking newer integrase strand transfer inhibitors (DTG, BIC) and DRV-based regimens.

Abstract
BACKGROUND Women face unique complexities in HIV treatment yet are underrepresented in antiretroviral therapy (ART) studies. OBJECTIVE This analysis assessed the one-year durability of the first integrase strand transfer inhibitor (INSTI)-based regimens prescribed to women in a large cohort of patients living with HIV in care. METHODS Women with HIV who initiated their first INSTI-containing regimen between 08/12/2013 and 11/30/2015 were identified in the OPERA cohort, a collaboration of 79 US outpatient clinics. Discontinuation within the first year of treatment with an INSTI was compared between dolutegravir (DTG), raltegravir (RAL) and elvitegravir (EVG), using multivariable Cox regression and Kaplan- Meier estimates. Virologic response and regimen modifications were described and compared across INSTIs. RESULTS A total of 537 treatment-naïve (DTG: 39%, EVG: 48%, RAL: 13%) and 878 treatmentexperienced (DTG: 57%, EVG: 29%, RAL: 13%) women were analyzed. In the first twelve months after initiation, women taking EVG or RAL were more likely to discontinue their initial INSTI than those taking DTG among both treatment-naïve (adjusted hazard ratio EVG vs. DTG: 1.59 (95% CI: 1.09, 2.39); RAL vs. DTG: 2.46 (1.49, 4.05)) and treatment-experienced women (EVG vs. DTG: 1.39 (1.02, 1.88); RAL vs. DTG: 2.17 (1.51, 3.12)). Following discontinuation of the initial INSTI, women commonly switched to a regimen containing a different drug from the INSTI class (treatment-naïve DTG: 34%, RAL: 33% EVG: 41%; treatment-experienced DTG: 23%, RAL: 19% EVG: 41%). CONCLUSION In treatment-naïve and treatment-experienced women living with HIV, women taking DTG had the lowest risk for early (≤1 year) discontinuation.

Abstract
BACKGROUND Pretreatment and acquired drug resistance mutations (DRMs) can limit antiretroviral therapy effectiveness. METHODS We review prevalence of DRMs with resistance to nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs), focusing on lamivudine and rilpivirine, from 127 articles with >100,000 individuals with HIV-1 infection. RESULTS Estimated global prevalence of pretreatment resistance to any NRTI was 4% and to any NNRTI was 6%. Most prevalent DRMs resistant to lamivudine or rilpivirine were at positions E138 (4%), V179 (1%) and M184 (1%). Estimated acquired DRM prevalence was 58% for any NRTIs and 67% for any NNRTIs, most frequently at positions M184 (58%) and Y181 (21%). CONCLUSIONS This review suggests low risk of lamivudine- or rilpivirine-resistant mutations in treatment-naive, HIV-1-infected individuals.

Abstract
INTRODUCTION Two-drug regimens (2-DR) have the potential to be a viable solution to the challenges of treatment complexity, cost, adverse effects and contraindications. We sought to describe the real-world use and effectiveness of 2-DR among persons living with HIV (PLHIV) in the United States. METHODS We analysed data for 10,190 treatment-experienced patients from the OPERA® Observational Database initiating a new 2-DR or three-drug regimen (3-DR) between 1 January 2010 and 30 June 2016. Multivariate Cox Proportional Hazards models were used to estimate the association among 2-DR or 3-DR initiation and virologic suppression (viral load (VL) <50 copies/mL), virologic failure (2 VLs > 200 copies/mL or 1 VL > 200 copies/mL + discontinuation) or regimen discontinuation. RESULTS Patients initiating a 2-DR (n = 1337, 13%) were older, and more likely to have a lower CD4 count, a history of AIDS and comorbid conditions than patients initiating a 3-DR. There was no difference between groups in time to virologic suppression (aHR: 1.00 (95% CI: 0.88, 1.13)) among viraemic patients (baseline VL ≥ 50 copies/mL, n = 4180), or time to virologic failure (aHR: 1.15 (95% CI: 0.90, 1.48)) among virologically stable patients (baseline VL < 50 copies/mL, n = 6010). However, time to discontinuation was shorter following 2-DR than 3-DR initiation (aHR: 1.51 (95% CI: 1.41, 1.61)). CONCLUSIONS In this large cohort of treatment-experienced patients, 2-DR prescriptions were common and more frequent among patients with significant comorbidity. Virologic response was similar, but duration of use was shorter with a 2-DR than a 3-DR, suggesting that 2-DRs may be a virologically effective treatment strategy for treatment-experienced PLHIV with existing comorbidities.

Abstract
Abstract
Background
Limited data exist on the risk of type 2 diabetes mellitus (T2DM) with the use of integrase inhibitors. We assessed the risk of incident T2DM with antiretroviral therapy (ART).
Methods
ART-naïve (ART-N) and -experienced, suppressed (ART-ES; baseline viral load 13 years of age initiating dolutegravir (DTG), elvitegravir/cobicistat (EVG/c), raltegravir (RAL) or boosted darunavir (bDRV) in the OPERA® cohort. After excluding prevalent prediabetes/T2DM and missing baseline covariates, incidence rates of T2DM (i.e., diagnosis, antidiabetic drug, and/orHbA1C >6.5%) were estimated with Poisson regression. The association between core agents and incident T2DM was estimated with multivariate Cox proportional hazards regression adjusted for age, sex, race, HCV co-infection and BMI at baseline. Median (IQR) absolute BMI change from baseline was evaluated at 6, 12, 18, and 24 months in those who developed incident T2DM and those who did not. All analyses were stratified by ART experience.
Results
Individuals prescribed these ART regimens varied significantly (Figure 1). Overall, incidence rate per 1,000 person-years was low for T2DM (ART-N IR: 9.1; 95% CI: 7.5, 10.9; ART-ES IR: 13.3; 95% CI: 11.6, 15.2; Figure 2). Among ART-N initiators, no statistical difference was observed in the risk of progression to T2DM between DTG and EVG/c (aHR: 0.70; 95% CI: 0.47, 1.05) or bDRV (aHR: 0.53; 95% CI: 0.26, 1.04); RAL could not be evaluated due to the small number of T2DM events. Among ART-ES initiators; no difference was observed between DTG and EVG/c (aHR: 0.96; 95% CI: 0.70, 1.33), RAL (aHR: 1.17; 95% CI: 0.70, 1.96) or bDRV (aHR: 0.90; 95% CI: 0.57, 1.42) (Figure 3). A greater absolute change in BMI was observed for ART-N initiators developing T2DM at all timepoints; reaching statistical significance at 12 and 18 months (Figure 4). No differences were observed for ART-ES initiators.
Conclusion
Incident T2DM was uncommon among ART-N and ART-ES persons initiating DTG, EVG/c, RAL or bDRV in this large clinical population. None of the comparisons between DTG and other core agents showed a statistically significant increased risk of T2DM. However, due to the small number of events in the ART-N population differential risk cannot be excluded and monitoring HbA1c remains prudent.

Abstract
Abstract
Background
A potential association between integrase inhibitor (INSTI) use and weight gain has been reported in people living with HIV (PLWH). We examined body mass index (BMI) increases after a switch to dolutegravir (DTG), elvitegravir/cobicistat (EVG/c), raltegravir (RAL), rilpivirine (RPV), or boosted darunavir (bDRV) among virologically suppressed ART-experienced PLWH.
Methods
ART-experienced, suppressed (ART-ES; baseline viral load < 200 copies/mL) PLWH ≥ 18 years of age initiating DTG, EVG/c, RAL, RPV, or bDRV for the first time were identified in the OPERA® cohort. The association between core agents and mean increases in BMI at 6, 12, and 24 months was estimated with multivariable linear regression. Inverse probability-of-censoring weights (IPCW) were used to account for censoring (regimen discontinuation, loss to follow-up, death, pregnancy, or no BMI measured). Analyses were stratified by baseline BMI categories (underweight: <18.5, normal weight: ≥18.5 to <25, overweight: ≥25 to <30, obese: ≥30).
Results
At baseline, endocrine disorders were reported in >40% of PLWH receiving DTG and RAL; >60% were overweight/obese in all groups (Figure 1). Mean BMI (unadjusted) increased for all ARVs over time, with changes at 24 months ranging from 0.30 (DRV) to 0.83 (RPV, Figure 2). At 6 months, the adjusted mean BMI increase was statistically smaller with EVG/c, RAL, and bDRV (range –0.15 to –0.30) than with DTG (Figure 3); these differences only remained significantly different for bDRV at 12 (–0.29) and 24 months (–0.29, Figure 3). Among those with a normal baseline BMI, the adjusted mean change in BMI at 12 months was smaller with EVG/c, bDRV, and RAL than DTG (range –0.26 to –0.27). Among overweight PLWH, the adjusted mean BMI increase was statistically smaller with bDRV than DTG (–0.32, Figure 4). Results were consistent in IPCW estimates.
Conclusion
The majority of PLWH on stable ART in this US-based cohort were overweight/obese at the time of switch to the regimens of interest. Small mean increases in BMI for all regimens were noted over time, for which the clinical significance is not yet known. Apparent differences in BMI changes favoring EVG/c, RAL, and bDRV vs. DTG over the short term were largely attenuated with longer follow-up, with significant differences mainly observed in those with a normal BMI at baseline.

Abstract
Background Psychiatric outcomes are common among people living with HIV and may be associated with specific antiretroviral use. We evaluated the occurrence of psychiatric outcomes in patients taking dolutegravir (DTG)-containing regimens compared with five other core agents. Methods Patients in the OPERA database prescribed regimens based on DTG, efavirenz (EFV), raltegravir (RAL), darunavir (DRV), rilpivirine (RPV), or elvitegravir (EVG) for the first time between 1 January 2013 and 31 December 2015 were analyzed. Psychiatric outcomes included diagnoses of anxiety, depression, insomnia, or suicidality during core agent exposure. Multivariable Cox analysis models were used to assess time to psychiatric outcomes between core agents stratified by psychiatric history, with DTG as the referent. Results A total of 13,261 patients initiated a regimen of interest (DTG: 2783; RAL: 979; EVG: 3895, EFV: 1746, RPV: 1921, DRV: 1937). Psychiatric history was common, with varied prevalence across groups (DTG 38%, EFV 24%, RAL 40%, DRV 34%, RPV 29%, EVG 31%). Among patients without a psychiatric history, the likelihood of a psychiatric outcome during follow up did not differ between DTG and the other core agents. Among patients with a psychiatric history, risk during follow up for patients taking DTG was equivalent (versus RPV), marginally reduced (versus RAL and EFV), or reduced (versus EVG and DRV). Conclusions In a large cohort of HIV+ patients in care, patients with a psychiatric history appeared channeled towards drugs with known favorable psychiatric safety profiles, including DTG. Despite this, DTG exposure was not associated with an increased risk of psychiatric outcomes during follow up in patients with or without a psychiatric history.

Abstract
Background and Objectives The standard of care for HIV treatment is a three-drug regimen consisting of two nucleoside reverse transcriptase inhibitors (NRTIs) and either a non-nucleoside reverse transcriptase inhibitor, a protease inhibitor (PI) or an integrase strand transfer inhibitor. Darunavir boosted with ritonavir (DRV/r) is the only preferred PI in the US Department of Health and Human Services (DHHS) HIV treatment guidelines for antiretroviral-naïve patients, recommended in combination with tenofovir/emtricitabine for antiretroviral-naïve patients. For treatment-experienced and certain antiretroviral-naïve patients, abacavir and lamivudine (ABC/3TC) in combination with DRV/r is considered an effective and tolerable alternative, despite limited research on the effectiveness of this particular combination. This study evaluated virologic outcomes in treatment-experienced patients taking ABC/3TC + DRV/r compared to treatment-experienced patients taking ABC/3TC with any other PI. Methods Treatment-experienced HIV-infected patients initiating their first regimen containing ABC/3TC in combination with any PI in the year 2005 or later were selected from the Observational Pharmaco-Epidemiology Research and Analysis (OPERA®) cohort, a prospective observational cohort reflecting routine medical care. Viral load measurements taken during follow-up were compared between patients taking ABC/3TC + DRV/r and ABC/3TC with a PI other than DRV/r. Logistic regression models were fit to assess the association between regimen exposure and viral load suppression. Results A total of 151 patients initiating ABC/3TC + DRV/r and 525 patients initiating ABC/3TC + a non-darunavir PI were included. Patients in both treatment groups had comparable clinical indicators (viral load, CD4) at baseline. A regimen of ABC/3TC + DRV/r was more likely to be prescribed in the later years of the study period, leading to a shorter median follow-up in the DRV/r treatment group (as-treated analysis: 14 vs. 17 months, p = 0.04; intent-to-treat analysis: 33 vs. 68 months, p < 0.001). Multivariable logistic regression models accounting for year of regimen initiation, among other factors, indicated no statistically significant differences in achieving an undetectable viral load for patients taking DRV/r with ABC/3TC compared with other PIs, both in the as-treated (odds ratio [95 % confidence interval]: 0.84 [0.53–1.34]) and intent-to-treat analyses (0.82 [0.48–1.40]). Patients in both treatment groups also showed similar reductions in viral load (median darunavir vs. non-darunavir: −23.0 vs. −23.0 copies/mL; p = 0.72) and gains in CD4 T cell counts (median darunavir vs. non-darunavir: 106 vs. 108 cells/mm3; p = 0.59] while being treated with the regimen of interest. Conclusions Patients receiving ABC/3TC + DRV/r appear to experience similar treatment benefit to patients taking ABC/3TC with other PIs in terms of achieving suppression, as well as absolute reductions in viral load and CD4 lymphocyte gains.

Abstract
SETTING Kinshasa, Democratic Republic of Congo. OBJECTIVE To identify programmatic interventions for improved survival in patients receiving treatment for tuberculosis (TB) at primary care clinics. DESIGN Retrospective cohort of adult patients initiating anti-tuberculosis treatment between January 2006 and May 2007. RESULTS Among 5685 patients, 390 deaths occurred during anti-tuberculosis treatment, of which half (52%) did so during the first 2 months. Patients with smear-negative pulmonary TB were at greater risk of death in the first 2 months of treatment (human immunodeficiency virus [HIV] positive HR 1.49, 95%CI 0.89-2.49; HIV-negative HR 1.77 95%CI 1.06-2.95), but not thereafter. Patients with extra-pulmonary TB were at increased risk of death in the first 2 months of anti-tuberculosis treatment if they were non-HIV-infected (HR 2.42, 95%CI 1.52-3.85), and were half as likely to die during the remainder of treatment (HIV-positive HR 0.46, 95%CI 0.22-0.97; HIV-negative HR 0.47, 95%CI 0.23-0.94). Antiretroviral therapy (ART) reduced the risk of death by an estimated 36% (HR 0.64, 95%CI 0.37-1.11). CONCLUSION High mortality in the first months of anti-tuberculosis treatment could be reduced by addressing diagnostic delays, particularly for extra-pulmonary and smear-negative TB cases and, in HIV-infected patients, by initiation of ART soon after starting anti-tuberculosis treatment.

Abstract
Objectives:To assess subclinical central nervous system (CNS) involvement in primary Sjögren syndrome (pSS), by comparing standard brain MRI, in-depth neuropsychological testing and 99mTc-ECD brain single-photon emission computed tomography (SPECT) of patients with pSS with matched controls.Methods:10 women (<55 years old), with pSS defined using European–American criteria, presence of anti-SSA and/or anti-SSB antibodies and no history of neurological involvement were prospectively investigated, and compared with 10 age- and sex-matched controls. All subjects underwent, within 1 month, brain MRI, neuropsychological testing, including overall evaluation and focal cognitive function assessment, and 99mTc-ECD brain SPECT.Results:99mTc-ECD brain SPECT abnormalities were significantly more common in patients with pSS (10/10) than controls (2/10; p<0.05). Cognitive dysfunctions, mainly expressed as executive and visuospatial disorders, were also significantly more common in patients with pSS (8/10) than controls (0/10; p<0.01). Notably, between-group comparisons enabled a significant correlation to be established between neuropsychological assessment and 99mTc-ECD brain SPECT abnormalities in patients with pSS (rs = 0.49, p<0.01). MRI abnormalities in patients and controls did not differ significantly.Conclusions:Neuropsychological testing and 99mTc-ECD brain SPECT seem to be the most sensitive tools to detect subclinical CNS dysfunction in pSS. The strong correlation between cortical hypoperfusion in 99mTc-ECD brain SPECT and cognitive dysfunction suggests an organic aetiology of CNS dysfunction in pSS. These data should be confirmed in a larger study.

Abstract
Objective:To characterise major infectious complications and analyse potential risk factors in patients with Wegener granulomatosis (WG).Methods:Data from 113 patients with WG (69 male) followed at least once between January 1984 and March 2006 in our internal medicine department, were analysed retrospectively.Results:A total of 35 patients (mean (SD) age at WG diagnosis: 50.2 (13.05) years) developed 53 major infections. Infections were: bronchopneumonias (n = 19), herpes zoster recurrences (n = 9), cellulitis (n = 4), prostatitis (n = 4), spondylodiscitis and septic arthritis (n = 3), digestive tract infections (n = 2), Enterococcus faecalis or Staphylococcus aureus septicaemia (n = 2), viral hepatitis B reactivations (n = 2), post transfusion HIV infection with fatal cerebral toxoplasmosis, oesophageal candidiasis, disseminated herpes simplex and cytomegalovirus infection, cytomegalovirus retinitis, herpetic keratitis, herpetic stomatitis, Serratia sp. node suppuration and fever resolving under broad spectrum antibiotics (n = 1 each). Half of the major infectious episodes occurred within 3 years after WG diagnosis. Eight (7%) patients died, with two (2%) infection-related deaths. Patients diagnosed with WG before 1996 had a significantly higher rate of infection than those diagnosed later (48% vs 24%, p = 0.02). Cyclophosphamide and corticosteroids were independently associated with significantly higher risk of major infection (p<0.05 and <0.001, respectively). All patients treated since 1993 received antipneumocystosis prophylaxis.Conclusion:Cyclophosphamide and corticosteroids were associated with higher risk of infection. Despite systematic cotrimoxazole prophylaxis, major infections, mostly bronchopneumonias and herpes zoster recurrences, were still common in the course of WG.

Abstract
BACKGROUND Leptin is a secreted adipocyte hormone that plays a key role in the regulation of body weight homeostasis. The leptin effect on human white adipose tissue (WAT) is still debated. OBJECTIVE The aim of this study was to assess whether the administration of polyethylene glycol-leptin (PEG-OB) in a single supraphysiological dose has transcriptional effects on genes of WAT and to identify its target genes and functional pathways in WAT. MATERIALS AND METHODS Blood samples and WAT biopsies were obtained from 10 healthy nonobese men before treatment and 72 h after the PEG-OB injection, leading to an approximate 809-fold increase in circulating leptin. The WAT gene expression profile before and after the PEG-OB injection was compared using pangenomic microarrays. Functional gene annotations based on the gene ontology of the PEG-OB regulated genes were performed using both an 'in house' automated procedure and GenMAPP (Gene Microarray Pathway Profiler), designed for viewing and analyzing gene expression data in the context of biological pathways. RESULTS Statistical analysis of microarray data revealed that PEG-OB had a major down-regulated effect on WAT gene expression, as we obtained 1,822 and 100 down- and up-regulated genes, respectively. Microarray data were validated using reverse transcription quantitative PCR. Functional gene annotations of PEG-OB regulated genes revealed that the functional class related to immunity and inflammation was among the most mobilized PEG-OB pathway in WAT. These genes are mainly expressed in the cell of the stroma vascular fraction in comparison with adipocytes. CONCLUSION Our observations support the hypothesis that leptin could act on WAT, particularly on genes related to inflammation and immunity, which may suggest a novel leptin target pathway in human WAT.

Abstract
PURPOSE Cyclophosphamide in monthly intravenous bolus is used to treat severe forms of systemic sclerosis with pulmonary involvement. Since 1996, cyclophosphamide therapeutic intensification with autologous haematopoietic stem cells transplantation allowed significant improvement in skin and functional scores in severe systemic sclerosis. Cyclophosphamide potential cardiotoxicity in this setting has been questioned. METHODS To analyse cyclophosphamide potential cardiopulmonary toxicity (as graded with WHO classification), we retrospectively studied all severe systemic sclerosis patients treated with cyclophosphamide either during autologous haematopoietic stem cells transplantation procedure (group A) or intravenous cyclophosphamide (group B) recruited in 7 French centers volunteers for the study. Parameters to evaluate heart and lung functions at inclusion, then at last follow-up between 6 and 12 months after start of treatment, were compared using the Mann-Whitney test. RESULTS (Mean+/-standard deviation): Groups A (N=14) and B (N=13) were similar at the beginning of the study in terms of skin, renal, heart and lung involvement. Cyclophosphamide total dose (/m(2)) received in group A was superior (P=0.02) to the one in group B. After respective follow-up of 10+/-2.8 (group A) and 9.9+/-2.7 (group B) months, cyclophosphamide cardio toxicity (group A: N=3; group B: N=2), evolution of the left ventricular ejection fraction and arterial and pulmonary pressures did not differ in the two groups. CONCLUSION In spite of higher cyclophosphamide doses during autologous haematopoietic stem cells transplantation than bolus treatment, cardiopulmonary toxicity appeared not increased. The ongoing European ASTIS trial will compare the respective benefits of these 2 cyclophosphamide regimens in severe Systemic sclerosis.
