Objectives: The COVID-19 pandemic's impact on initiation and effectiveness of antiretroviral therapy (ART) in people diagnosed with HIV remains unclear. We evaluated critical delays in HIV care in people diagnosed before and during the pandemic in ex-Aquitaine, France., Methods: We considered adults diagnosed with HIV-1 in 2018-2021 and enrolled in the ANRS CO3 AQUIVIH-NA and followed them until October 10, 2022 for those diagnosed during the pandemic (April 01, 2020-December 31, 2021) and until March 31, 2020 for historical controls. We compared their characteristics at inclusion and the median time between diagnosis and ART initiation, ART initiation and viral suppression, and diagnosis and virologic, suppression (effective management)., Results: Eighty-three individuals were diagnosed during the pandemic versus 188 during the prepandemic period. Median follow-up was 549 (interquartile range: 329-713) days. Populations were similar in sex, age, HIV acquisition mode, hospital type, and clinical characteristics at diagnosis; however, fewer were foreign-born during the pandemic (15.7% versus 33.5%, P = 0.003). The probability of ART initiation, therapeutic success, and effective management was higher in people living with HIV (PLWH) diagnosed during the pandemic in adjusted analyses (hazard ratio [HR]: 2.0; 95% CI: 1.5 to 2.7; HR: 1.7; 95% CI: 1.2 to 2.3; HR: 1.8; 95% CI: 1.3 to 2.6, respectively). Those diagnosed during the pandemic were 2.3 (95% CI: 1.2 to 4.1) times more likely to be virologically suppressed within six months of diagnosis compared with historical controls., Conclusions: Pandemic-related reorganizations may have resulted in newly diagnosed PLWH being prioritized; however, the lower proportion of foreign-born PLWH diagnosed during the pandemic period, likely because of reduced migration and potential delays in diagnosis, may contribute to these preliminary findings., Competing Interests: The authors declare no conflicts of interest in relation to this manuscript.

Background: Infective endocarditis (IE) is increasingly affecting older patients. However, data on their management are sparse, and the benefits of surgery in this population are unclear., Methods: We included patients with left-sided IE (LSIE) aged ≥ 80 years enrolled in a prospective endocarditis cohort managed in Aquitaine, France, from 2013 to 2020. Geriatric data were collected retrospectively to identify factors associated with the 1-year risk of death using Cox regression., Results: We included 163 patients with LSIE (median age, 84 years; men, 59%; rate of prosthetic LSIE, 45%). Of the 105 (64%) patients with potential surgical indications, 38 (36%) underwent valve surgery: they were younger, more likely to be men with aortic involvement, and had a lower Charlson comorbidity index. Moreover, they had better functional status at admission (ie, the ability to walk unassisted and a higher median activities of daily living [ADL] score; n = 5/6 vs 3/6, P = .01). The 1-year mortality rate in LSIE patients without surgical indications was 28%; it was lower in those who were operated on compared with those who were not despite a surgical indication (16% vs 66%, P < .001). Impaired functional status at admission was strongly associated with mortality regardless of surgical status. In patients unable to walk unassisted or with an ADL score <4, there was no significant surgical benefit for 1-year mortality., Conclusions: Surgery improves the prognosis of older patients with LSIE and good functional status. Surgical futility should be discussed in patients with altered autonomy. The endocarditis team should include a geriatric specialist., Competing Interests: Potential conflicts of interest . F.

Aim: To describe the effects of a summertime pause (SP) in immunoglobulin replacement therapy (IgRT). Patients & methods: We conducted a prospective single-center observational study, including 44 patients undergoing intravenous IgRT between May and June 2019 in a French teaching hospital. Results: IgRT was interrupted in 23 patients from June to October. Patients who underwent an SP were older, more likely to have secondary immunodeficiency (SID) and received lower doses of immunoglobulin and more antibiotics during winter. Most patients who did not undergo an SP had severe primary immunodeficiency. The SP did not increase the risk of infection, improved the quality of life and reduced treatment costs. Conclusion: SP in IgRT is a safe practice and should be considered for patients with mild SID.

Paroxysmal nocturnal hemoglobinuria (PNH) is a very rare clonal autoimmune disease manifesting with hemolysis, thrombosis, or bone marrow failure. We present an atypical association of myasthenia gravis, aplastic anemia, and PNH occurring years after thymectomy. While this association might be extremely rare, it may not be coincidental as there is a common pathophysiology between PNH and aplastic anemia, with the latter reported in several thymoma/thymectomy cases. Eculizumab was introduced with good efficacy and without safety concern in our patient, leading to long-term control of PNH without worsening of myasthenia gravis., (© 2021 The Authors. eJHaem published by British Society for Haematology and John Wiley & Sons Ltd.)

Background: Guidelines that detail preventive measures against Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae type b, and influenza are published annually in France to decrease the risk of severe infections in immunocompromised patients. We aimed at describing adherence to these guidelines by GPs in the management of their asplenic patients in France between 2013 and 2016., Method: We conducted a multicenter retrospective study between January 2013 and December 2016 in three French hospitals: asplenic adults were identified and their GPs were questioned. A descriptive analysis was performed to identify the immunization coverage, type and length of antibiotic prophylaxis, number of infectious episodes, and education of patients., Results: 103 patients were finally included in this study: only 57% were adequately vaccinated against Streptococcus pneumoniae or Neisseria meningitidis, 74% against Haemophilus influenzae type b, and 59% against influenza. Only 24% of patients received a combination of all four vaccinations. Two-thirds of patients received prophylactic antibiotics for at least 2 years. Overall, this study found that 50% of splenectomized patients experienced at least one pulmonary or otorhinolaryngological infection, or contracted influenza., Conclusions: These data match those reported in other countries, including Australia and the United Kingdom, meaning a still insufficient coverage of preventive measures in asplenic patients. Improved medical data sharing strategies between healthcare professionals, along with educational measures to keep patients and physicians up to date in the prevention of infections after splenectomy would improve health outcomes of asplenic patients.

Background: Antibiotic administration by subcutaneous (SC) injection is common practice in French geriatric wards as an alternative to the intravenous (IV) route, but few pharmacokinetic/pharmacodynamic data are available. Ertapenem is useful for the treatment of infections with ESBL-producing enterobacteria., Objectives: To report and compare ertapenem pharmacokinetic data between IV and SC routes in older persons., Methods: Patients >65 years of age receiving ertapenem (1 g once daily) for at least 48 h (IV or SC, steady-state) were prospectively enrolled. Total ertapenem concentrations [residual (C0), IV peak (C0.5) and SC peak (C2.5)] were determined by UV HPLC. Individual-predicted AUC0-24 values were calculated and population pharmacokinetic analyses were performed. Using the final model, a Monte Carlo simulation involving 10 000 patients evaluated the influence of SC or IV administration on the PTA. Tolerance to ertapenem and recovery were also monitored. ClinicalTrials.gov identifier: NCT02505386., Results: Ten (mean ± SD age=87±7 years) and 16 (age=88±5 years) patients were included in the IV and SC groups, respectively. The mean C0 and C2.5 values were not significantly different between the IV and SC groups (C0=12±5.9 versus 12±7.4 mg/L, P=0.97; C2.5=97±42 versus 67±41 mg/L, P=0.99). The mean C0.5 was higher in the IV group compared with the SC group (C0.5=184±90 versus 51±66 mg/L, P=0.001). The mean individual AUCs (1126.92±334.99 mg·h/L for IV versus 1005.3±266.0 mg·h/L for SC, P=0.38) and PTAs were not significantly different between groups. No severe antibiotic-related adverse effects were noted., Conclusions: SC administration of ertapenem is an alternative to IV administration in older patients., (© The Author(s) 2019.

Hepatitis E virus is a new emergent virus causing acute self-limiting hepatitis, but may also cause extrahepatic manifestations. Hepatitis E virus should be systematically considered in patients with cutaneous small-vessel vasculitis and cytolytic hepatitis., Competing Interests: None declared.

Background: The usage of left-ventricular-assist device (LVAD) is increasing in patients presenting with advanced heart failure. However, device-related infections are a challenge to recognize and to treat, with an important morbidity and mortality rate. The role of nuclear medicine imaging remains not well established for LVAD infections. The present study compared the accuracy of positron emission tomography/computed tomography with 18 F-fludeoxyglucose ( 18 F-FDG PET/CT) and radiolabeled leucocyte scintigraphy for the diagnosis of infections in patients supported with a continuous-flow LVAD., Methods: From a prospectively maintained database, we retrospectively analyzed the diagnostic performance of radiolabeled leucocyte scintigraphy and 18 F-FDG PET/CT in 24 patients who had a LVAD with a suspected device-related infection. Both examinations were routinely performed in all patients. Infection was assessed by the International Society for Heart and Lung Transplantation criteria., Results: Twenty-four patients were included: 15 had a specific VAD infection (5 cardiac-LVAD and 10 driveline), 6 had a VAD-related infection, while 3 patients had a non-VAD-related infection. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 95.2%, 66.7%, 95.2%, 66.7%, and 91.6%, respectively, for 18 F-FDG-PET; and 71.4%, 100%, 100%, 33.3%, and 75%, respectively, for leucocyte scintigraphy. 18 F-FDG PET/CT showed significantly higher sensitivity (P = 0.01) than leucocyte scintigraphy., Conclusion: 18 F-FDG PET/CT and radiolabeled leucocyte scintigraphy single-photon emission computed tomography carry high performance in the diagnostic of LVAD infections. 18 F-FDG PET/CT shows significantly higher sensitivity and could be proposed as first-line nuclear medicine procedure.

Background: Since the introduction of antiretroviral therapy (ART), human immunodeficiency virus (HIV)-infected patients have a drastically improved prognosis but at the same time they are also more affected by non-HIV related complications, such as chronic kidney disease. The objective of our study was to investigate the effect of proteinuria and tenofovir (TDF)-containing ART regimens on the temporal evolution of estimated glomerular filtration rate (eGFR)., Methods: Between April 2008 and October 2012, we enrolled 395 patients with a complete renal evaluation among patients from the ANRS C03 Aquitaine cohort, a prospective hospital-based cohort of HIV-1-infected patients under routine clinical management in southwestern France. eGFR was estimated at each patient follow-up visit. A linear mixed model was used to analyze eGFR dynamics, accounting for change in TDF by modeling eGFR trajectory according to treatment periods., Results: At inclusion, 56.7% of patients were treated with TDF-containing ART regimens; prevalence of glomerular and tubular proteinuria was 7.9 and 10.8% respectively. A 1-year increase of cumulative exposure to TDF was significantly associated with a mean eGFR decrease of 1.27 mL/min/1.73 m2 (95% CI [-2.14 to -0.41]). Only a urine protein to creatinine ratio >100 mg/mmol and/or a urine albumin to creatinine ratio >70 mg/mmol were associated with eGFR trajectory (mean slope 6.18 mL/min/1.73 m2 per year; 95% CI [2.71 to 9.65]), whereas TDF use was not associated with such eGFR temporal evolution., Conclusion: Decline in kidney function is limited under routine clinical management with monitoring of renal function and interventions including decision to continue or discontinue TDF., (© 2017 S.

Aim: To date, neither the benefit of mycophenolic acid (MPA) therapeutic drug monitoring (TDM), the prodrug of mycophenolate mofetil (MMF), nor the optimal monitoring technique have been established in autoimmune diseases. This study was undertaken to confirm, in a cohort of new patients, the plasma MPA thresholds previously published in patients with systemic lupus erythematosus (SLE) or vasculitis., Methods: MPA areas under the concentration-time curves between 0 and 12 h, 12 h trough concentrations and pre-dose concentrations (C0 ) were determined for 23 patients with SLE and 21 with systemic vasculitis. The relationship between patients' pharmacokinetic (PK) variables and their clinical outcomes during follow-up were analyzed., Results: In both autoimmune diseases, at PK assessment, median MPA C0 for patients with uncontrolled disease was significantly lower than that of patients with stable disease or in remission, 1.6 mg l(-1) (IQR 0.9-2.1 mg l(-1)) vs. 2.95 mg l(-1) (IQR 1.38-3.73 mg l(-1)) for SLE (P = 0.048) and 1.55 mg l(-1) (IQR 0.98-2.18 mg l(-1)) vs. 3 mg l(-1) (IQR 2.2-4.4 mg l(-1)) for vasculitis (P = 0.016). According to our receiver operating characteristics curve analysis, a C0 threshold of 2.5-3 mg l(-1) was best able to discriminate a flare (SLE: 88% sensitivity, 80% specificity; vasculitis: 100% sensitivity, 90% specificity). Patients with C0 ≥ 2.5-3 mg l(-1) at inclusion had better clinical outcomes during the 12 months following PK assessment., Conclusion: Provided that the benefit of TDM in patients with autoimmune diseases could be confirmed by randomized, controlled trials, it might be based on the C0 measured approximately 12 h post-dose., (© 2014 The British Pharmacological Society.)

Objectives: To assess changes in locomotor function in HIV-infected patients and to evaluate the determinants of variations in lower limb muscle performance., Design: Longitudinal study within the ANRS CO3 Aquitaine Cohort., Methods: Standardized locomotor tests, including global functional capacity [6-min walk distance (6MWD)] and lower limb muscle performance tests [five times sit-to-stand (5STS) test], were performed in HIV-infected adults at baseline and 2-year follow-up. Evolution of performances and determinants of 5STS time were studied in linear mixed-effects models., Results: At baseline (354 patients, 90% on antiretroviral treatment), median 5STS time was 9.8 s and 6MWD 549 m. Poorer performances were associated with falls, reported by 12% of 178 patients at follow-up. Estimated mean deterioration was +0.24 s/year (P < 10) for 5STS time and -11 m/year (P < 10) for 6MWD. In multivariable analyses, older age was associated with worse baseline 5STS time (+0.47 s/10-year age increase; P = 10), but not with further deterioration. Deterioration was greater in prior injecting drug users compared to others (difference in slope +0.62 s/year; P = 0.04). 5STS time at any time point was worse in patients with history of cerebral AIDS conditions (+2.47 s; P < 10) and diabetes (+0.95 s; P = 0.02) than in others. No significant associations were found for antiretroviral treatment type, viral load or CD4 cell count., Conclusion: Compared to published data from healthy persons of similar age, baseline 5STS time and 6MWD were poorer in HIV-infected adults and associated with subsequent falls. Test performances deteriorated further over time. Age, diabetes, neurologic complications and injection drug use, rather than virologic factors, contribute to variations in lower limb muscle performance.

Background: In high-income settings, the spectrum of morbidity and mortality experienced by Human Immunodeficiency Virus (HIV)-infected individuals receiving combination antiretroviral therapy (cART) has switched from predominantly AIDS-related to non-AIDS-related conditions. In the context of universal access to care, we evaluated whether that shift would apply in Brazil, a middle-income country with universal access to treatment, as compared to France., Methods: Two hospital-based cohorts of HIV-infected individuals were used for this analysis: the ANRS CO3 Aquitaine Cohort in South Western France and the Evandro Chagas Research Institute (IPEC) Cohort of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. Severe morbid events (AIDS- and non-AIDS-related) were defined as all clinical diagnoses associated with a hospitalization of ≥48 hours. Trends in the incidence rate of events and their determinants were estimated while adjusting for within-subject correlation using generalized estimating equations models with an auto-regressive correlation structure and robust standard errors., Result: Between January 2000 and December 2008, 7812 adult patients were followed for a total of 41,668 person-years (PY) of follow-up. Throughout the study period, 90% of the patients were treated with cART. The annual incidence rate of AIDS and non-AIDS events, and of deaths significantly decreased over the years, from 6.2, 21.1, and 1.9 AIDS, non-AIDS events, and deaths per 100 PY in 2000 to 4.3, 14.9, and 1.5/100 PY in 2008. The annual incidence rates of non-AIDS events surpassed that of AIDS-events during the entire study period. High CD4 cell counts were associated with a lower incidence rate of AIDS and non-AIDS events as well as with lower rates of specific non-AIDS events, such as bacterial, hepatic, viral, neurological, and cardiovascular conditions. Adjusted analysis showed that severe morbidity was associated with lower CD4 counts and higher plasma HIV RNAs but not with setting (IPEC versus Aquitaine)., Conclusions: As information on severe morbidities for HIV-infected patients remain scarce, data on hospitalizations are valuable to identify priorities for case management and to improve the quality of life of patients with a chronic disease requiring life-long treatment. Immune restoration is highly effective in reducing AIDS and non-AIDS severe morbid events irrespective of the setting.

Romiplostim is a thrombopoietin-receptor agonist approved to treat chronic immune thrombocytopenia (ITP). We treated eight patients with acute or persistent primary ITP, severe clinical bleeding, and resistance to corticosteroids and/or intravenous immunoglobulins (IVIg). Romiplostim, initially administered at 2 or 3 μg/kg/week, was subsequently increased to achieve and maintain platelet-count responses and control bleeding. Seven patients' platelet counts rose above 30 G/L, representing ≥twofold increases, within a median of 14 days after 1-5 infusions. The weekly dose reached 9 μg/kg at week 5 for three patients; the other patients' ITPs were controlled with ≤6 μg/kg/week. No thromboembolic events occurred. Five patients received rituximab concomitantly with romiplostim, four of whom could stop romiplostim within 2 months, thereby demonstrating rituximab efficacy. All three patients treated with romiplostim alone required maintenance therapy. Thus, romiplostim represents an alternative for patients with severe acute or persistent ITP refractory to conventional therapy.

Motor impairment is highly prevalent in HIV-infected patients. Here, we assess associations between peripheral muscular deficits as evaluated by the 5 sit-to-stand test (5STS) and structural integrity of the motor system at a central level. Eighty-six HIV-infected patients receiving combination antiretroviral therapy and with no major cerebral events, underwent an MRI scan and the 5STS. Out of 86 participants, forty presented a score greater than two standard deviations above mean normative scores calculated for the 5STS and were therefore considered as motor-impaired. MRI-structural cerebral parameters were compared to the unimpaired participants. Fractional Anisotropy (FA), Axial Diffusivity (AD) and Radial Diffusivity (RD), reflecting microstructural integrity, were extracted from Diffusion-Tensor MRI. Global and regional cerebral volumes or thicknesses were extracted from 3D-T1 morphological MRI. Whereas the two groups did not differ for any HIV variables, voxel-wise analysis revealed that motor-impaired participants present low FA values in various cortico-motor tracts and low AD in left cortico-spinal tract. However, they did not present reduced volumes or thicknesses of the precentral cortices compared to unimpaired participants. The absence of alterations in cortical regions holding motor-neurons might argue against neurodegenerative process as an explanation of White Matter (WM) disorganization.

Objectives: Large unselected studies on representative samples of HIV-infected patients with a whole battery of neuropsychological tests and cerebral MRI scan are required to assess the frequency of neurocognitive impairment (NCI), the determinants of mild neurocognitive disorders (MNDs), or HIV-associated dementia (HAD) and the relationship between NCI and MRI scan findings., Methods: Investigation of 400 consecutively enrolled HIV-1-infected adults from the ANRS CO3 Aquitaine Cohort, using standardized neurocognitive tests chosen to achieve consistency with Frascati's criteria. Half of the patients had a cerebral MRI scan allowing gray and white matter volume measurement. Factors associated with NCI were studied by logistic regression models., Results: Median age of participants was 47 years, 79% were male and 89% received combination antiretroviral treatment (cART), of whom 93% had plasma HIV RNA below 500 copies/ml. Median CD4 cell count was 515 cells/μl. Prevalence of NCI was 59%, including 21% of asymptomatic NCI, 31% of MND, and 7% of HAD. A low level of education, prior neurologic AIDS-defining disorders event, anxiety, depressive symptoms, and prior history of brain damage were independently associated with MND or HAD, but neither HIV nor cART-related variables. The presence of NCI was significantly associated with lower gray matter fraction., Interpretation: In this large unselected cohort, a high prevalence of symptomatic neurocognitive disorders was mainly related to its traditional determinants and associated with gray matter atrophy at early stages of the disease.
