RESUMO
OBJECTIVES: We aimed to assess among men who have sex with men (MSM) risk factors for HIV infection, to identify those who require urgent pre-exposure prophylaxis (PrEP) prescription. METHODS: All participants enrolled in the placebo arm of the ANRS IPERGAY trial, or infected between screening and day 0, were included. Baseline characteristics were described and HIV incidence rate ratios (RRs) were estimated with their 95% CIs. RESULTS: 203 MSM were included with a median follow-up of 9 months. During the study period, 16 participants acquired HIV infection while not receiving tenofovir disoproxil and emtricitabin (TDF/FTC) over 212.4 person-years (PYs) of follow-up (incidence rate 7.5/100 PYs, 95% CI: 4.3 to 12.2). Being enrolled in Paris was associated with a significant increased risk of HIV infection (RR: 4.1; 95% CI: 1.1 to 28.3). A high number of sexual partners in prior 2 months (≥10 vs <5) and of condomless receptive anal sex episodes in prior 12 months (>5 vs <5) were strong predictors for HIV acquisition (RR: 10.6 (2 to 260.2) and 3.3 (1.2 to 10.2), respectively). Those who reported more often or only receptive sexual practices were also at increased risk (RR: 9.8 (2.0 to 246.6)). The use of recreational drugs in prior 12 months, especially gamma hydroxybutarate/gamma butyrolactone (RR: 5.9; 95% CI: 2 to 21.7), was associated with a significantly increased risk of HIV acquisition even after adjustment for sexual practices. CONCLUSIONS: MSM who have frequent condomless receptive anal sex and multiple partners, or use recreational drugs should be targeted in priority for PrEP prescription especially if they live in an area with a high prevalence of HIV infection.

OBJECTIVES: As trends in new HIV diagnoses represent a measure of the HIV epidemic, we conducted a 6-year longitudinal study to evaluate the change in rates of new HIV diagnosis, stratified by birthplace, HIV risk groups and CD4 cell count at diagnosis in a large French multicentre cohort. STUDY DESIGN: We performed a retrospective cohort study using data from the mainland French Dat'AIDS cohort. METHODS: Data were obtained for subjects with a new HIV diagnosis date between 2013 and 2018. HIV diagnosis date was defined as the date of the first known positive HIV serology. RESULTS: Between 2013 and 2018, a total of 68,376 people living with HIV (PLHIV) were followed in the Dat'AIDS cohort; 9543 persons were newly diagnosed with HIV. The annual number of new HIV diagnoses decreased from 1856 in 2013, to 1149 in 2018 (-38.1%), P = 0.01; it was more pronounced among subjects born in France, from 858 to 484 (-43.6%), P < 0.01, than in those born abroad (-23.8%, from 821 to 626, P = 0.13). Among subjects born in France, the decrease over the period was -46.7% among men who have sex with men (MSM), -43.5% for heterosexual women and -33.3% for heterosexual men. CONCLUSION: Our findings show changes in HIV epidemiology in PLHIV born in France, with a decline around 40% in new HIV diagnoses, and a more pronounced decrease among MSM and heterosexual women. Our results support the long-term effectiveness of the antiretroviral therapy as a prevention strategy among the various tools for HIV prevention.

Natural killer (NK) cell functions are regulated by diverse inhibitory and activating receptors, including killer cell immunoglobulin-like receptors (KIR), which interact with human leukocyte antigen (HLA) class I molecules. Some KIR/HLA genetic combinations were reported associated with spontaneous clearance (SC) of hepatitis C virus (HCV) but with discordant results, possibly reflecting KIR and/or HLA gene polymorphism according to populations. KIR/HLA genetic combinations associated with both an exhaustive NK and T cell repertoire were investigated in a cohort of HIV-HCV co-infected individuals with either SC (n = 68) or chronic infection (CI, n = 163) compared to uninfected blood donors [controls (Ctrl), n = 100]. Multivariate analysis showed that the HLA C2C2 environment was associated with SC only in European HIV-HCV co-infected individuals [odds ratio (OR) = 4·30, 95% confidence interval = 1·57-12·25, P = 0·005]. KIR2D+ NK cell repertoire and potential of degranulation of KIR2DL1/S1+ NK cells were similar in the SC European cohort compared to uninfected individuals. In contrast, decreased frequencies of KIR2DS1+ and KIR2DL2+ NK cells were detected in the CI group of Europeans compared to SC and a decreased frequency of KIR2DL1/S1+ NK cells compared to controls. Regarding T cells, higher frequencies of DNAX accessory molecule-1 (DNAM-1)+ and CD57+ T cells were observed in SC in comparison to controls. Interestingly, SC subjects emphasized increased frequencies of KIR2DL2/L3/S2+ T cells compared to CI subjects. Our study underlines that the C2 environment may activate efficient KIR2DL1+ NK cells in a viral context and maintain a KIR2DL2/L3/S2+ mature T cell response in the absence of KIR2DL2 engagement with its cognate ligands in SC group of HCV-HIV co-infected European patients.

PURPOSE: Invasive fungal diseases and especially Cryptococcus neoformans infections are increasingly reported in patients with hematological malignancies receiving ibrutinib, a Bruton's tyrosine kinase inhibitor. PATIENTS AND METHOD: We reported three additional cases and reviewed 16 previous published cases together with cases from the international pharmacovigilance database. RESULTS: Patients were mainly treated for chronic lymphocytic leukemia. Cryptococcosis mostly occurred during the first six months (66%) and especially the first two months (44%) of treatment. Clinical presentation is often pulmonary (68%) and the outcome is usually favorable despite ibrutinib continuation. CONCLUSION: Clinicians must be aware of this infection in patients with hematological malignancies on ibrutinib.

BACKGROUND: Little data is available on HIV-infected patients aged over 75years. METHODS: A descriptive study of HIV-infected patients aged over 75years was conducted in six hospitals of the Pays de la Loire region, France. Socio-demographic, immuno-virological, and therapeutic characteristics were collected via an electronic medical record software (Nadis®). To assess frailty, a simplified geriatric assessment was conducted during an HIV routine visit. RESULTS: Among the 3965 patients followed in the six centers, 65 (1.6%) were aged over 75years. From January to May 2016, 51 patients were included in the study: median age 78.7years, male patients 74.5%, homosexual transmission 41.2%, living at home 98% and single in 54.5% of cases, median duration of HIV infection 18.8years, median CD4 nadir 181 cells/mm3; CDC stage C 36.4%. All patients were on antiretroviral therapy and 98% of them had an HIV RNA<50c/mL; 82% of patients had at least one comorbidity and 58% at least two comorbidities. Eleven of 51 patients (21.6%) were diagnosed as at risk of frailty and 2/51 (3.9%) were considered frail. Cognitive disorders were diagnosed in 60.8%, depression in 35.3%, malnutrition in 25.5%, and vitamin D deficiency in 45.9%. CONCLUSIONS: HIV-infected patients aged above 75years are well-managed, but the prevalence of geriatric comorbidities is high.

INTRODUCTION: Gastrointestinal disorders in solid organ recipients may have various origins including cryptosporidiosis and microsporidiosis. The prevalence of these infections is poorly known in solid organ transplant (SOT) patients in industrialized countries. METHODS: We prospectively assessed the infectious causes of diarrhea in SOT patients. Secondary objectives were to gain further insight into the main characteristics of cryptosporidiosis, and to assess risk factors for this infection. All adult kidney and/or pancreas recipients presenting with diarrhea and admitted to our facility between May 1, 2014 and June 30, 2015 were enrolled. A stool sample was analyzed using a standardized protocol including bacteriological, virological, and parasitological investigations. Data related to clinical symptoms, immunosuppression, and environmental potential risk factors were collected through a self-administered questionnaire and computerized medical records. RESULTS: Out of 73 enrolled patients, 36 had infectious diarrhea (49.3%). Viruses ranked first (17/36), followed by parasites and fungi (11/17). Cryptosporidiosis was the most common parasitic disease (n=6 patients). We observed four microsporidiosis cases. The estimated prevalence of cryptosporidiosis and microsporidiosis in this cohort was 3.7 and 2.40/00, respectively. No significant risk factor for cryptosporidiosis or microsporidiosis, neither environmental nor immunological, could be evidenced. CONCLUSION: Both cryptosporidiosis and microsporidiosis represent a significant cause of diarrhea in kidney transplant recipients.

OBJECTIVES: Protection of French young infants against pertussis only relies on their relatives' vaccination. The alternative is vaccination of pregnant women against pertussis (cocooning strategy), but this strategy is not yet recommended in France. We assessed the acceptance of this strategy among French postpartum women and health professionals. PATIENTS AND METHODS: We performed a multicenter survey in 2016 among postpartum women and health professionals (family physicians, obstetricians-gynecologists, midwives, and medical students) to determine the acceptance of anti-pertussis vaccination. We evaluated knowledge, perception, and attitude towards vaccination to identify factors associated with acceptance. RESULTS: Questionnaires were completed by 52% (1208/2337) of women and 40% (694/1754) of health professionals. Seventy-seven per cent of women (95% CI: 74-79) and 93% of health professionals (95% CI: 91-95) were favorable to anti-pertussis vaccination of pregnant women. Thirty-three per cent (227/687) of health professionals believed that pertussis induced life-long immunity and 20% (136/687) of them were not aware of the cocooning strategy. In multivariate analysis, factors associated with acceptance among women were younger age, higher knowledge, having received advice during pregnancy, being vaccinated against influenza, and having never refused any vaccine; among health professionals, factors associated with acceptance were belief that inactivated vaccines are obstetrically safe, regular practice of influenza vaccination in pregnant women, pertussis cocooning strategy, and never prescribing preventive homeopathy for influenza. CONCLUSION: Vaccination of pregnant women against pertussis should be well-accepted by informed mothers and health professionals. If this strategy were to be implemented in France, efforts should be made towards adequate information.

OBJECTIVES: Our aim was to investigate factors associated with baseline blood telomere length in participants enrolled in NEAT 001/ANRS 143, a randomized, open-label trial comparing ritonavir-boosted darunavir (DRV/r) plus raltegravir (RAL) with DRV/r plus tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in antiretroviral therapy (ART)-naïve HIV-positive adults. METHODS: A cross-sectional study of 201 randomly selected participants who had stored samples available was carried out. We measured telomere length (i.e. the relative telomere length, calculated as the telomere to single copy gene ratio) at baseline with monochrome quantitative multiplex polymerase chain reaction (PCR). We used multivariable predictive linear regression to calculate mean differences and 95% confidence intervals (CIs) for the association between baseline telomere length and baseline characteristics. RESULTS: The baseline characteristics of the 201 participants did not differ from those of the 805 participants in the parent trial population: 89% were male, the mean age was 39 years, 83.6% were Caucasian, 93% acquired HIV infection via sexual transmission, the mean estimated time since HIV diagnosis was 2.1 years, the mean HIV-1 RNA load was 4.7 log10 HIV-1 RNA copies/mL, the mean nadir and baseline CD4 counts were 301 and 324 cells/µL, respectively, and the mean CD4:CD8 ratio was 0.4. In the univariate analysis, shorter telomere length was associated with older age (per 10 years) (P < 0.001), HIV-1 RNA ≥ 100 000 copies/mL (P = 0.001), CD4 count < 200 cells/µL (P = 0.037), lower CD4:CD8 ratio (P = 0.018), statin treatment (P = 0.004), and current alcohol consumption (P = 0.035). In the multivariable analysis, older age (P < 0.001) and HIV RNA ≥ 100 000 copies/mL (P = 0.054) were independently associated with shorter telomere length. CONCLUSIONS: Both age and HIV RNA viral load correlated with shorter blood telomere length in untreated persons living with HIV. These results suggest that HIV infection and age have synergistic and independent impacts upon immunosenescence.

BACKGROUND: Rapid antiretroviral therapy (ART) initiation has been proven beneficial for patients and the community. We aimed to analyze recent changes in timing of ART initiation in France and consequences of early start. METHODS: We selected from a prospective nationwide cohort, on 12/31/2017, patients with HIV-1 infection diagnosed between 01/01/2010 and 12/31/2015. We described time from (1) diagnosis to first specialized medical encounter, (2) from this encounter to ART initiation, (3) from diagnosis to first undetectable HIV viral load (VL). We analyzed the determinants of measured temporal trends. A multivariate logistic regression was performed to assess characteristics related with 1-year retention in care. RESULTS: In the 7 245 included patients, median time (1) from HIV diagnosis to first medical encounter was 13 (IQR: 6-32) days, (2) to ART initiation was 27 (IQR: 9-91) days, decreasing from 42 (IQR: 13-272) days in 2010 to 18 (IQR: 7-42) in 2015 (p<0.0001), (3) to first undetectable VL was 257 (IQR: 151-496) days, decreasing from 378 (IQR: 201-810) days in 2010 to 169 (IQR: 97-281) in 2015. After one year, proportion of patients alive and still in care was significantly lower in those in the lower quartile of time from first encounter to ART (<9 days) than those in the higher quartile (>90 days), 79.9% and 85.2%, respectively (p<0.0001). CONCLUSIONS: In a country with unrestricted rapid access to ART, keeping recently diagnosed HIV infected patients in care remains challenging. Starting ART rapidly did not seem to be profitable for all and every patient.

AIM: Ageing HIV-infected patients controlled by antiretroviral therapy (ART) frequently present age-related comorbidities, such as cardiovascular (CV) events, diabetes, dyslipidaemia, hypertension and chronic kidney disease (CKD). The prevalence of these comorbidities was evaluated in a cohort of long-term-monitored ART-controlled HIV-infected patients, then followed by a search into whether oxidative stress, like inflammation, might be associated with metabolic parameters and/or comorbidities. METHODS: Included were 352 long-term ART patients who started with protease inhibitors (PIs) in 1997-1999. They were evaluated at their final visit, 11 years later, for previous CV events, prevalence of diabetes, LDL-related and atherogenic (high TG/HDL) dyslipidaemias, hypertension and CKD. Also measured were circulating biomarkers to explore oxidative stress (Lp-PLA2, oxLDL, oxLDL/LDL ratio, paraoxonase and arylesterase activities), inflammation/immune activation (hsCRP, hsIL-6, D dimer, soluble CD14, ß2 microglobulin, cystatin C), adipokines and insulin resistance. Levels were compared in patients with and without each comorbidity or condition using non-parametric correlation tests and multivariate adjusted analyses. RESULTS: At the final visit, 81.5% of patients were male and were aged (median, IQR) 49 years (45-56); BMI was 23.0 kg/m2 (21.1-25.4), CD4+ lymphocytes were 620 cells/mm3 (453-790) and 91.5% had undetectable HIV-1 viral loads. The prevalence of diabetes was 11%, and LDL-related dyslipidaemia 28%, atherogenic dyslipidaemia 9%, hypertension 28%, CKD 9% and previous CV events 9%. Diabetes and atherogenic dyslipidaemia were associated with increased oxidative stress and independently with inflammation. LDL-related dyslipidaemia and impaired fasting glucose were associated with increased oxidative stress. No association of these biomarkers was detected with hypertension, CKD and previous CV events. CONCLUSION: In long-term-treated HIV-infected patients with frequent comorbid conditions, oxidative stress could be contributing to diabetes and LDL-related and atherogenic dyslipidaemias independently of inflammation.

INTRODUCTION: The metabolic pathways of dolutegravir suggest a potential predator effect of nevirapine on dolutegravir pharmacokinetics and switching from a nevirapine- to a dolutegravir-containing regimen could lead to a lower and suboptimal exposure to dolutegravir several weeks after the switch in case of persistent inducer effect. PATIENTS AND METHOD: Prospective, pilot, single-arm, open-label, non-comparative, bicentric study to evaluate the pharmacokinetics, virologic outcomes, safety, and patient satisfaction of switching from abacavir/lamivudine and nevirapine to a single tablet of abacavir/lamivudine/dolutegravir. The primary endpoint was the maintenance of virologic suppression (HIV-1 RNA<50 copies/mL) at week 12. Secondary endpoints were virologic suppression at week 48, safety and tolerability, patient satisfaction, and pharmacokinetic interaction between nevirapine and dolutegravir. Fifty-three adults on stable abacavir/lamivudine and nevirapine regimen for a median duration of 6years and virologically suppressed for 9.6years were included. RESULTS: Dolutegravir reached steady state by week 4/week 12 when expected by day 5/day 10. All subjects maintained plasma HIV-RNAË50 copies/mL at week 12 and week 48. Abacavir/lamivudine/dolutegravir was well-tolerated, with two cases of serious adverse events deemed unrelated to study drugs (coronary syndrome in both cases), and one discontinuation for renal impairment at week 24 with a slight improvement after dolutegravir discontinuation. Level of treatment satisfaction remained high after the switch. CONCLUSION: The transient predator effect of nevirapine on dolutegravir had no clinical consequences after switching from nevirapine to dolutegravir, neither on safety nor maintenance of virologic suppression. It also had no consequences on patient satisfaction.

BACKGROUND: Both human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections have been reportedly associated with a higher risk of diabetes mellitus (DM) but results are conflicting. AIMS: To determine whether there is an association between chronic HCV and the incidence of DM, and to study the role of factors such as cirrhosis, IFN-based HCV therapy, sustained virologic response (SVR) and chronic HBV infection among patients living with HIV (PLHIV) followed in a large French multicentre cohort in the combination antiretroviral therapy (cART) era. METHODS: All PLHIV followed up in the Dat'AIDS cohort were eligible. Cox models for survival analysis were used to study the time to occurrence of DM. RESULTS: Among 28 699 PLHIV, 4004 patients had chronic HCV infection. The mean duration of HCV follow-up was 12.5 ± 8.1 years. The rate ratio of DM was 2.74 per 1000 person-years. By multivariate analysis, increasing age, body mass index>25, AIDS status, nadir CD4 cell count ≤200/mm3 , detectable HIV viral load and cirrhosis (HR 2.26 95% CI 1.14-1.18; P < 0.0001) were predictors of DM, whereas longer cART duration was associated with a lower risk of DM. Chronic HCV and HBV infection and IFN-based HCV therapy were not associated with DM. In a subanalysis among HCV-infected patients, SVR was not related to DM. CONCLUSIONS: Our study shows that in the HIV population, cirrhosis is associated with an increased occurrence of DM, but not chronic HCV infection or duration of HCV infection.

OBJECTIVES: To characterize multidrug-resistant tuberculosis (MDR-TB) patients treated in a low endemic area in France and to determine risk factors for resistance. We also analyzed the efficacy and tolerability of tuberculosis (TB) treatment. METHODS: Between 2002-2013, all MDR-TB patients diagnosed in western France (hospitals belonging to the GERICCO group) were retrospectively included, with a follow-up period running until 2016. A case-control study (1:2), matched according to age, sex, and year of diagnosis, was performed to assess socio-demographic and clinical data, treatment strategies, and outcomes for the MDR-TB patients and controls treated for drug-susceptible tuberculosis during the same period. RESULTS: Of 134 TB patients, 44 were MDR-TB and 90 were drug-susceptible TB. Of the 44 MDR-TB patients (35 MDR and nine extensively drug-resistant [XDR]), 33 (75%) were males; the median age was 33 years; and 27 (61%) were born in Eastern Europe. Prior treatment failure was more frequently reported for XDR-TB (8/9) in Georgian patients. In multivariate analysis, risk contacts and prior TB history were associated with MDR-TB. Treatment failure was associated with MDR/XDR-TB and miliary TB. CONCLUSION: In western France, MDR-TB more frequently occurred in recent migrants from high-risk countries with a previous history of at-risk contact with other MDR-TB patients or previous TB treatment failure.

Switch of antiretroviral therapy in virologically suppressed HIV-infected patients is frequent, to prevent toxicities, for simplification or convenience reasons. Pretherapeutic genotypic resistance testing on RNA can be lacking in some patients, which could enhance the risk of virologic failure, if resistance-associated mutations of the new regimen are not taken into account. Proviral DNA resistance testing in 69 virologically suppressed patients on antiretroviral treatment with no history of virological failure were pair-wised compared with pre-ART plasma RNA resistance testing. The median time between plasma (RNA testing) and whole blood (proviral DNA testing) was 47 months (IQR 29-63). A stop codon was evidenced in 23% (16/69) of proviral DNA sequences; these strains were considered as defective, non-replicative, and not taken into consideration. Within the non defective strains, concordance rate between plasma RNA and non-defective proviral DNA was high both on protease (194/220 concordant resistance-associated mutations=88%) and reverse transcriptase (28/37 concordant resistance-associated mutations=76%) genes. This study supports that proviral DNA testing might be an informative tool before switching antiretrovirals in virologically suppressed patients with no history of virological failure, but the interpretation should be restricted to non-defective viruses.

OBJECTIVES: Studies evaluating the efficacy and safety of the fixed-dose combination ledipasvir (LDV)/sofosbuvir (SOF) in patients coinfected with HIV-1 and hepatitis C virus (HCV) have mainly included treatment-naïve patients without cirrhosis. We aimed to evaluate the efficacy and safety of this combination in treatment-experienced patients with and without cirrhosis. METHODS: We conducted a multicentre, open-label, double-arm, nonrandomized study in patients coinfected with HIV-1 and HCV genotype 1 with and without cirrhosis, who had good viral suppression on their antiretroviral regimens. All patients were pretreated with a first-generation NS3/4A protease inhibitor (PI) plus pegylated interferon/ribavirin. Patients received a fixed-dose combination of LDV/SOF for 12 weeks, or for 24 weeks if cirrhosis was present. The primary endpoint was a sustained virological response (SVR) 12 weeks after the end of therapy. Secondary endpoints included safety, pharmacokinetics and patient-reported outcomes. RESULTS: Of the 68 patients enrolled, 39.7% had cirrhosis. Sixty-five patients [95.6%; 95% confidence interval (CI): 87.6-99.1%; P < 0.0001] achieved an SVR, with similar rates of SVR in those with and without cirrhosis. Tolerance was satisfactory, with mainly grade 1 or 2 adverse events. Among patient-reported outcomes, only fatigue significantly decreased at the end of treatment compared with baseline [odds ratio (OR): 0.36; 95% CI: 0.14-0.96; P = 0.04]. Mean tenofovir area under the plasma concentration-time curve (AUC) at week 4 was high, with mean ± SD AUC variation between baseline and week 4 higher in cirrhotic than in noncirrhotic patients (3261.57 ± 1920.47 ng/mL vs. 1576.15 ± 911.97 ng/mL, respectively; P = 0.03). Mild proteinuria (54.4%), hypophosphataemia (50.0%), blood bicarbonate decrease (29.4%) and hypokalaemia (13.2%) were reported. The serum creatinine level was not modified. CONCLUSIONS: LDV/SOF provided a high SVR rate in PI-experienced subjects coinfected with HCV genotype 1 and HIV-1, including patients with cirrhosis.

In an era when most individuals with treated HIV infection can expect to live into old age, clinicians should proactively review their patients' current and future treatment needs and challenges. Clinical guidelines acknowledge that, in the setting of virological suppression, treatment switch may yield benefits in terms of tolerability, regimen simplification, adherence, convenience and long-term health considerations, particularly in the context of ageing. In this paper, we review evidence from six key clinical studies on switching virologically suppressed patients to regimens based on integrase strand transfer inhibitors (INSTIs), the antiretroviral class increasingly preferred as initial therapy in clinical guidelines. We review these studies and focus on the virological efficacy, safety, and tolerability of switching to INSTI-based regimens in suppressed HIV-positive individuals. We review the early switch studies SWITCHMRK and SPIRAL [assessing a switch from a ritonavir-boosted protease inhibitor (PI/r) to raltegravir (RAL)-containing regimens], together with data from STRATEGY-PI [assessing a switch to elvitegravir (EVG)-containing regimens; EVG/cobicistat (COBI)/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) vs. remaining on a PI/r-containing regimen], STRATEGY-NNRTI [assessing a switch to EVG/COBI/FTC/TDF vs. continuation of a nonnucleoside reverse transcriptase inhibitor (NNRTI) and two nucleoside reverse transcriptase inhibitors (NRTIs)], STRIIVING [assessing a switch to a dolutegravir (DTG)-containing regimen (abacavir (ABC)/lamivudine (3TC)/DTG) vs. staying on the background regimen], and GS study 109 [assessing a switch to EVG/COBI/FTC/tenofovir alafenamide fumarate (TAF) vs. continuation of FTC/TDF-based regimens]. Switching to INSTI-containing regimens has been shown to support good virological efficacy, with evidence from two studies demonstrating superior virological efficacy for a switch to EVG-containing regimens. In addition, switching to INSTI regimens was associated with improved tolerability and greater reported patient satisfaction and outcomes in some studies. INSTI-based regimens offer an important contemporary switch option that may be tailored to meet and optimize the needs of many patients.
