Brief Report: Incidence and Management of Complex Kidney Situations Among On-Demand and Daily HIV Pre-Exposure Prophylaxis Users

BACKGROUND

We evaluated complex pre-exposure prophylaxis (PrEP) situations linked to kidney issues in a cohort of on-demand and daily PrEP users.

SETTING

We conducted a single-center retrospective cohort study in France including all PrEP users who received a tenofovir disoproxil (TD)-emtricitabine (FTC) prescription between January 1, 2012 and December 31, 2019 with at least 1 creatinine measurement available before and after PrEP initiation.

METHODS

A complex kidney situation (CKS) was defined as an estimated glomerular filtration rate (eGFR) <60 mL/minute/1.73m 2 on 2 consecutive measurements. We estimated the incidence of this event, described case management, and identified associated factors using a Cox model.

RESULTS

Three thousand one hundred and fourteen individuals were included in this study. Almost all were men (99%) with a median age of 35 years, 25% had an eGFR <90 mL/minute/1.73m 2 at baseline, and 65% used on-demand PrEP. Nine users (0.29%) had a CKS at baseline; 8/9 initiated on-demand PrEP without renal function worsening after a median (interquartile range [IQR]) follow-up time of 14 months (7-31). Thirteen cases of CKS occurred during the follow-up for a 0.25 per 100 person-years incidence (95% confidence interval [CI]: [0.14; 0.45]). On-demand PrEP was used in 7/13 participants with no further episode of confirmed eGFR <60 mL/minute/1.73m 2 after a 17-month median follow-up (IQR 4-18). CKS was associated with an age ≥50 years (hazard ratio [HR] 13, 95% CI: [4-39]) or with a baseline eGFR <90 mL/minute/1.73m 2 (HR 34, 95% CI: [4-261]). 9/22 CKS were linked to high-protein intake for weight training.

CONCLUSIONS

CKS were rare in our cohort. On-demand PrEP did not result in subsequent renal function worsening in these few situations.

Updated mortality and causes of death in 2020-2021 in people with HIV: a multicenter study in France

OBJECTIVE

The aim of this study was to assess updated mortality and causes of death in people with HIV (PWH) in France.

DESIGN AND METHODS

We analyzed all deaths in PWH followed up between January 1, 2020, and December 31, 2021, in 11 hospitals in the Paris region. We described the characteristics and causes of death among deceased PWH, and evaluated the incidence of mortality and associated risk factors using a multivariate logistic regression.

RESULTS

Of the 12 942 patients followed in 2020--2021, 202 deaths occurred. Mean annual incidence of death [95% confidence interval (95% CI)] was 7.8 per 1000 PWH (6.3-9.5). Forty-seven patients (23%) died from non-AIDS nonviral hepatitis (NANH)-related malignancies, 38 (19%) from non-AIDS infections (including 21 cases of COVID-19), 20 (10%) from AIDS, 19 (9%) from cardiovascular diseases (CVD), 17 (8.4%) from other causes, six (3%) from liver diseases, and five (2.5%) from suicides/violent deaths. The cause of death was unknown in 50 (24.7%) patients. Risks factors for death were age [adjusted odds ratio (aOR) 1.93; 1.66-2.25 by additional decade), AIDS history (2.23; 1.61-3.09), low CD4 + cell count (1.95; 1.36-2.78 for 200-500 cells/μl and 5.76; 3.65-9.08 for ≤200 versus > 500 cells/μl), and viral load more than 50 copies/ml (2.03; 1.33-3.08), both at last visit.

CONCLUSION

NANH malignancies remained in 2020-2021 the first cause of death. COVID-19 accounted for more than half of the mortality related to non-AIDS infections over the period. Aging, AIDS history, and a poorer viro-immunological control were associated with death.

Safety and efficacy of switching to elvitegravir, cobicistat, emtricitabine, tenofovir disoproxil fumarate in treatment-experienced people with HIV: a multicenter cohort study

OBJECTIVES

We assessed the virologic efficacy of switching to co-formulated elvitegravir, cobicistat, emtricitabine, tenofovir disoproxil fumarate (E/C/F/TDF) in patients with controlled HIV infection.

METHODS

We conducted a retrospective multicenter observational cohort study including adult patients with controlled HIV-1 infection on any stable antiretroviral (ART) regimen, who switched to E/C/F/TDF. Success was measured by the proportion of patients with plasma viral load < 50 copies/ml at W48 using the FDA snapshot algorithm. We also assessed risk factors associated with virological failure (VF).

RESULTS

382 patients with HIV RNA < 50 copies/mL who switched to E/C/F/TDF were included in the study. Most patients (69.9%) were male, with median age 44 years (IQR 38-51), who had been on ART for a median of 7 years (IQR 4-13). Median CD4 count was 614/mm³ and 24.6% of the patients had a history of previous virological failure. The reasons for switching were simplification (67.0%) and tolerance issues (22.0%). At week 48, 314 (82.0% [95% CI 78.4-86.0]) patients had HIV RNA < 50 copies/mL, 13 (3.5% [95% CI 3.64-8.41]) experienced virological failure. Genotype at failure was available in 6/13 patients with detection of resistance-associated mutations to integrase inhibitors and NRTIs in 5/6 (83.3%) patients. We found no predictive factor associated with virological failure except for a borderline significance with the duration of viral suppression before the switch. Tolerability of E/C/F/TDF was good with 23/382 (6.0%) patients experiencing mild adverse reactions.

CONCLUSION

In our cohort, switching well-suppressed patients to E/C/F/TDF resulted in few virologic failures and was well tolerated. However, resistance to integrase inhibitors emerged in patients with virological failure.

Brief Report: Efficacy and Safety of Efavirenz, Raltegravir, and Dolutegravir in HIV-1/TB Coinfection. A Multicenter Retrospective Cohort Study in France

BACKGROUND

There are limited data comparing the efficacy and safety of raltegravir and dolutegravir to that of efavirenz in HIV-1/tuberculosis (TB) coinfected patients.

METHODS

We conducted a 10-year retrospective study in 4 centers in France. We included all HIV-1/tuberculosis coinfected patients starting antiretroviral therapy with a rifampicin-based regimen, with a plasma HIV RNA level (VL) > 1000 copies/mL. The primary endpoint was the proportion of patients with virological success that is, with VL <50 copies/mL at W48 using an Intention-To-Treat analysis, using last-observation-carried-forward to impute missing data. We also assessed antiretroviral therapy safety, analyzing treatment discontinuation for adverse events.

RESULTS

Between 2010 and 2020, 117 patients were included. Thirty-nine (33.3%) were treated with raltegravir and 2 nucleoside reverse transcriptase inhibitors (NRTIs), 19 (16.2%) with dolutegravir (and 2 NRTIs) and 59 (50.4%) with efavirenz (and 2 NRTIs). At W48, the primary endpoint was achieved in 24 patients (61.5%) in the raltegravir group, in 12 (63.2%) in the dolutegravir group, and in 41 (69.5%) in the efavirenz group using an Intention-To-Treat analysis ( P = 0.68). Emergence of drug resistance in patients with virological failure, defined as a VL >50 copies/mL, was observed in 3 patients with efavirenz and one patient with raltegravir. Rate of treatment discontinuation for drug-related adverse events was 10.3%, 10.6%, 16.9% for raltegravir, dolutegravir and efavirenz respectively ( P = 0.67).

CONCLUSIONS

In this retrospective cohort study, raltegravir and dolutegravir yielded similar efficacy and safety results to efavirenz for the treatment of HIV-1/TB coinfected patients.

Mortality of People Living with HIV in Paris Area from 2011 to 2015

In high-income countries, causes of death in people living with HIV (PLHIV) have changed. Three French national surveys from 2000 to 2010 showed a decrease in AIDS-related and an increase in non-AIDS-related deaths. Deaths notified in PLHIV followed between January 1, 2011 and December 31, 2015 in 1 of 13 participating hospitals northeast of Paris area were described. Risk factors for death were assessed, using a multivariable logistic regression model. Of 14,403 individuals, 295 died. Median age at death was 52 years (interquartile range = 47-60) and 77% were men. Sixty-seven individuals (23%) died from non-AIDS-defining nonviral hepatitis-related (NaNH) malignancy, 40 (14%) from AIDS, 34 (12%) from cardiovascular disease (CVD), 33 (11%) from non-AIDS infection, 21 (7%) from liver disease, and 12 (4%) from suicide. Men and women born in sub-Saharan Africa had a lower adjusted odds ratio (aOR) of dying than men having sex with men (MSM) born in France (0.70, 95% confidence interval = 0.45-1.09; and 0.45, 0.28-0.73, respectively). Risk factors for death were older age (aOR = 2.26, 1.36-3.77 for 40-49 years and 2.91, 1.75-4.84 for >50 years vs. 18-39 years), male intravenous drug users (IVDU) transmission (2.24, 1.42-3.54 vs. MSM born in France), AIDS (2.75, 2.10-3.59), antiretroviral therapy initiation in earlier periods, time since HIV diagnosis <1 year, low CD4 cell count nadir, hepatitis B virus and/or hepatitis C virus coinfection (1.69, 1.23-2.30), and psychiatric disorders (1.73, 1.27-2.38). Our study confirms the increasing frequency of non-AIDS-related deaths, mainly NaNH malignancies and CVD, in PLHIV, justifying overall and in some specific populations (psychiatric and IVDU) prevention and screening.

Does region of origin influence the timing and outcome of first-line antiretroviral therapy in France?

OBJECTIVES

The aim of the study was to assess whether the timing of combination antiretroviral therapy (cART) initiation, the choice of cART and virological response differ in migrants versus European natives in the north and east of Paris area, after dissemination of French recommendations for universal treatment.

METHODS

Antiretroviral therapy-naïve HIV-1-infected adults with at least two follow-up visits at one of 15 participating centres between 1 January 2014 and 31 March 2015 were included in the study. Factors associated with cART initiation before 31 March 2015, with protease inhibitor (PI)-containing cART among individuals initiating cART, and with 1-year virological success after cART initiation were assessed using multivariable logistic regression models. Sex, age, region of origin [Western Europe, sub-Saharan Africa (SSA) or other], HIV transmission group, baseline AIDS status, CD4 cell count and plasma viral load (VL), and hepatitis B and/or C virus infection were considered in the analyses.

RESULTS

Among 912 individuals, only 584 (64%) started cART during the study period. After adjustment, migrants from SSA were half as likely to initiate cART and to have a subsequent virological response compared with individuals from Western Europe [adjusted odds ratio (aOR) 0.54; 95% confidence interval (CI) 0.36-0.82; and aOR 0.52; 95% CI 0.28-0.98, respectively]. PI-containing cART was more frequently prescribed in migrants from SSA, in people with lower CD4 cell counts and in people with higher VL.

CONCLUSIONS

Even in the context of universal cART recommendations and of free access to care, migrants from SSA still have delayed access to cART and a lower virological response. Efforts are still necessary to provide immediate cART to all people living with HIV.

Management of accidental exposure to HIV: the COREVIH 2011 activity report

BACKGROUND

Post-exposure prophylaxis (PEP) relies on procedures allowing quick access to treatment in case of accidental exposure to viral risk (AEV). Occupational blood exposure (OBE) affects mainly caregivers; these accidents are monitored and assessed by the inter-regional center for nosocomial infections (C-CLIN), occupational physicians, and infection control units. They are classified apart from sexual exposure for which there is currently no monitoring.

METHODS

Data was extracted from the COREVIH (steering committee for the prevention of HIV infection) 2011 activity reports (AR), available online. Data collection was performed using a standardized grid.

RESULTS

Twenty-four out of 28 AR were available online. Nine thousand nine hundred and twenty AEV were reported, 44% of OBE, and 56% of sexual and other exposures. PEP was prescribed in 8% of OBE and in 77% of sexual exposures. The type of PEP was documented in 52% of the cases. Follow-up was poorly documented.

CONCLUSION

AR provide an incomplete and heterogeneous review of exposure management without any standardized data collection. The difficulties encountered in data collection and monitoring are due to differences in care centers (complex patient circuits, multiple actors) and lack of common dedicated software. Sexual exposures account for 50% of AEV and most are treated; but they are incompletely reported and consequently not analyzed at the regional or national level. A typical AR collection grid is being studied in 2 COREVIH, with the objective to improve collection and obtain useful national data.

Persistent low-level HIV-1 RNA between 20 and 50 copies/mL in antiretroviral-treated patients: associated factors and virological outcome

OBJECTIVES

The aim of our study was to identify factors associated with persistent low-level viraemia (LLV) in HIV-infected patients under suppressive antiretroviral therapy and to assess the virological outcome of these patients.

METHODS

LLV was defined as at least two HIV-1 RNA values between 20 and 50 copies/mL during 1 year of follow-up. We compared patients with all values <20 copies/mL (LLV-) and patients with LLV (LLV+). The 'blip ratio' was defined as (number of HIV-1 RNA values >50 copies/mL)/(number of HIV-1 RNA determinations) before study inclusion.

RESULTS

Among the 656 patients included, 5.8% were in group LLV+. CDC stage B/C at study inclusion and a higher blip ratio before the study period were the only factors independently associated with LLV. During the 1 year follow-up, the proportion of patients experiencing virological failure was not different between the LLV- and LLV+ groups, and 40% of patients shifted from LLV+ to LLV- status.

CONCLUSIONS

LLV was infrequent in our series and the follow-up did not evidence a higher rate of virological failure than in fully suppressed patients. LLV seems to be a transient phenomenon that might be driven by residual ongoing viral replication and/or viral release and/or accuracy of viral load assay at lower values.
