Abstract
To evaluate incidence of and risk factors for respiratory bacterial colonization and infections within 30 days from lung transplantation (LT). We retrospectively analyzed microbiological and clinical data from 94 patients transplanted for indications other than cystic fibrosis, focusing on the occurrence of bacterial respiratory colonization or infection during 1 month of follow-up after LT. Thirty-three percent of patients developed lower respiratory bacterial colonization. Bilateral LT and chronic heart diseases were independently associated to a higher risk of overall bacterial colonization. Peptic diseases conferred a higher risk of multi-drug resistant (MDR) colonization, while longer duration of aerosol prophylaxis was associated with a lower risk. Overall, 35% of lung recipients developed bacterial pneumonia. COPD (when compared to idiopathic pulmonary fibrosis, IPF) and higher BMI were associated to a lower risk of bacterial infection. A higher risk of MDR infection was observed in IPF and in patients with pre-transplant colonization and infections. The risk of post-LT respiratory infections could be stratified by considering several factors (indication for LT, type of LT, presence of certain comorbidities, and microbiologic assessment before LT). A wider use of early nebulized therapies could be useful to prevent MDR colonization, thus potentially lowering infectious risk.

Abstract
The COVID-19 pandemic is posing an unprecedented threat worldwide. One issue that has faltered, though, concerns the underestimated risk to trade all for COVID-19, misdiagnosing other potentially life-threatening diseases. Further still, the presence of respiratory symptoms in AIDS patients should stimulate more vigilant efforts to uncover other or additional infections. This case report highlights the pitfalls of diagnosing a rare pulmonary infection during the COVID-19 pandemic.

Abstract
The TANGO trial demonstrated the efficacy of lamivudine plus dolutegravir in virologically suppressed patients without previous virological failures (VFs). In this dataset from clinical practice investigating the impact of past nucleoside reverse-transcriptase inhibitor resistance on this strategy, the combination of M184V/I plus at least 1 thymidine analog-associated mutation significantly increased the risk of VF.

Abstract
In routine clinical practice, hepatitis C virus-infected patients can prematurely discontinue the prescribed regimen for several reasons. The aim of our study was to investigate sustained virological response (SVR12) rates in patients who prematurely discontinued directly acting antiviral (DAA) regimens and to assess the shortest effective duration of DAA able to lead to SVR12. We retrospectively collected the SVR rates of patients, registered in the NAVIGATORE-Lombardia Network database from January 2015, who discontinued DAAs before the predefined end of treatment. Overall, we included 365 patients, males were the majority (213, 58.4%), mean age was 60.5 years, and 53 (14.5%) patients were HIV-co-infected. Liver cirrhosis was observed in 251 (68.8%) subjects, and the most represented genotypes were 1b (n = 168, 46%) and 3 (n = 59, 16.2%). DAA was discontinued a median of 1 (IQR 1-4) weeks before the predefined EOT, with 164 (44.9%) patients stopping DAAs at least 2 weeks before the planned schedule. In patients with F0-F3 liver fibrosis, lower rates of SVR12 were observed in patients treated for <4 weeks: 50% (n = 2/4) vs. 99.1% (n = 109/110) for ≥4 weeks, p = 0.003. In patients with liver cirrhosis, lower rates of SVR12 were observed in patients treated <8 weeks: 83.3% (n = 25/30) vs. 94.6% (n = 209/221) for ≥8 weeks, p = 0.038. Despite premature discontinuation of DAA, high SVR12 rates were observed in a real-life setting for treatment lasting at least 4 weeks in patients with liver fibrosis F0-F3 and 8 weeks in those with liver cirrhosis. On this basis, feasibility of reducing DAA treatment duration should be explored in randomized clinical trials.

Abstract
The aim of this study was to explore the psychological impact of the initial stage of the 2019 coronavirus (COVID-19) pandemic on people living with HIV (PLWH), a population at increased risk of psychological distress. PLWH participated in an online survey exploring demographic and clinical data, physical symptoms, contact history, knowledge and concerns, precautionary measures and additional information about COVID-19 during the first phase of the pandemic in Italy. The Impact of Event Scale-Revised (IES-R) (identifying the COVID-19 pandemic as a specific traumatic life event) and the Depression, Anxiety and Stress Scale (DASS-21) also formed part of the survey. Out of 98 participants, 45% revealed from mild to severe psychological impact from COVID-19 according to IES-R. A lower percentage, instead, complained of significant levels of depression (14%), anxiety (11%) or stress (6%) according to DASS-21. Higher education, being unemployed, number of perceived COVID-19 physical symptoms, concerns about risk of contracting COVID-19 and the pandemic situation in Italy, and needing additional information to prevent COVID-19 infection were positively associated to a higher risk of negative psychological impact. Moreover, among the participants, female gender, age, fewer years from HIV diagnosis and not being aware of their own viremia were associated to a higher risk of negative psychological outcomes. Almost half of our PLWH sample experienced significant levels of distress related to the COVID-19 pandemic. Women, elderly patients and those with recent HIV diagnosis appear to be the more psychologically fragile subgroups. Our findings could help identify patients most in need of psychological interventions to improve the wellbeing of PLWH.

Abstract
Human monoclonal antibodies are safe, preventive, and therapeutic tools that can be rapidly developed to help restore the massive health and economic disruption caused by the coronavirus disease 2019 (COVID-19) pandemic. By single-cell sorting 4,277 SARS-CoV-2 spike protein-specific memory B cells from 14 COVID-19 survivors, 453 neutralizing antibodies were identified. The most potent neutralizing antibodies recognized the spike protein receptor-binding domain, followed in potency by antibodies that recognize the S1 domain, the spike protein trimer, and the S2 subunit. Only 1.4% of them neutralized the authentic virus with a potency of 1–10 ng/mL. The most potent monoclonal antibody, engineered to reduce the risk of antibody-dependent enhancement and prolong half-life, neutralized the authentic wild-type virus and emerging variants containing D614G, E484K, and N501Y substitutions. Prophylactic and therapeutic efficacy in the hamster model was observed at 0.25 and 4 mg/kg respectively in absence of Fc functions.

Abstract
The disease burden due to nontuberculous mycobacteria is growing worldwide, consequently to improved diagnostic abilities and an increase in the individuals at risk. Uncertainties exist about the right moment on which start treatment. We investigated the clinical features associated with starting an antimicrobial treatment in patients with nontuberculous mycobacterial lung disease among Italian physicians involved in the field. We found that in real life predictors of starting antimicrobial treatment are quite adherent to international guidelines, with some uncertainties regarding the implication of immunosuppressive drugs.

Abstract
BACKGROUND We explored predictors of CD4/CD8 ratio improvement and optimal immunological recovery (OIR) after initiation of antiretroviral therapy (ART) in naive people living with HIV (PLWH). METHODS Retrospective multicenter study including naive PLWH starting ART with 2 nucleos(t)ide reverse transcriptase inhibitors + 1 integrase strand transfer inhibitor (InSTI) or non-NRTI or protease inhibitor (PI). PLWH were followed from the time of ART initiation (baseline) to the discontinuation of first-line regimen, virological failure, death, or loss to follow-up. Estimated incidence and predictors of time to CD4/CD8 ratio normalization (defined as ≥1) and OIR (defined as CD4/CD8 ratio ≥ 1 plus CD4 ≥ 500 cells/µL plus CD4% ≥ 30%) were explored by Kaplan-Meier curves and Cox regression analysis. RESULTS Overall, 1428 PLWH (77.8% males, median age 39 years, 55.1% with positive cytomegalovirus (CMV) antibodies, median HIV-RNA 4.80 log copies/mL, median CD4 323 cells/µL, median CD4/CD8 ratio 0.32) were included, of which 21.5% (n = 307), 44.5% (n = 636), and 34% (n = 485) treated with InSTI-, PI-, and NNRTI-based regimens, respectively. The estimated proportion of CD4/CD8 normalization and OIR at 36 months was 38.6% and 32.9%, respectively. Multivariate analysis showed that InSTI-based regimens had a higher probability of CD4/CD8 ratio normalization and OIR both in the total population (P < 0.001 versus PI) and in advanced naive PLWH (P ≤ 0.001 versus PI and NNRTI). Moreover, subjects with positive CMV serology showed a lower probability of CD4/CD8 ratio normalization and OIR (P < 0.001). CONCLUSIONS InSTI-based regimens showed a better immune recovery, suggesting that the type of first-line ART can influence immune reconstitution. PLWH with positive CMV serology showed an increased risk of suboptimal immune recovery.

Abstract
Everyday functioning (EF) impairment is frequent in people living with HIV (PLWH). Our aim was to better explore EF and its association with PLWH cognition, by administering both the IADL scale, the most common functional scale, and a new and ecologic multi-domain (communication and financial skills) tool to measure EF as the University of California San Diego (UCSD) Performance-Based Skills Assessment-Brief Version (UPSA-B). Eighty-five PLWH on cART with very good immunological condition and 23 age- and education-matched healthy controls (HC) were enrolled. PLWH underwent a standardized neuropsychological battery plus IADL, and cognitive impairment was defined according to Frascati criteria. Both groups underwent the UPSA-B. Only 6 subjects (7%) were affected by cognitive impairment (asymptomatic profile). While IADL score was at ceiling for all patients, the UPSA-B total score was significantly worse in PLWH when compared with HC [mean 82.1 (SD 9.3) vs 89.2 (SD 6.2); p < 0.001]. At communication subtest, PLWH group and HC were significantly different (p = 0.002), while no difference emerged at financial skills (p = 0.096). Higher score at UPSA-B was independently associated with better global cognitive performance (composite Z-score) (β 7.79; p < 0.001). Also considering each single cognitive domain, UPSA-B performance (both total and at subtests) confirmed the association with neurocognitive performance. In conclusion, UPSA-B seems to better discriminate EF impairment than IADL in PLWH, and it was associated with cognitive functions, also in the absence of symptomatic cognitive impairment. Thus, it appears a promising tool in the context of HIV infection to avoid misdiagnosis and to better detect also mild EF.

Abstract
This study aims to assess the peripheral blood cell count "signature" of Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) to discriminate promptly between COronaVIrus Disease 19 (COVID-19) and community-acquired pneumonia (CAP). We designed a retrospective case-control study, enrolling 525 patients (283 COVID-19 and 242 with CAP). All patients had a fever and at least one of the following signs: cough, chest pain, or dyspnea. We excluded patients treated with immunosuppressants, steroids, or affected by diseases known to modify blood cell count. COVID-19 patients showed a significant reduction in white blood cells (neutrophils, lymphocytes, monocytes, eosinophils) and platelets. We studied these parameters univariately, combined the significant ones in a multivariate model (AUROC 0.86, Nagelkerke PSEUDO-R2 0.5, Hosmer-Lemeshow p-value 0.9) and examined its discriminative performance in an internally-randomized validation cohort (AUROC 0.84). The cut-off selected according to Youden's Index (-0.13) showed a sensitivity of 84% and a specificity of 72% in the training cohort, and a sensitivity of 88% and a specificity of 73% in the validation cohort. In addition, we determined the probability of having COVID-19 pneumonia for each Model for possible Early COvid-19 Recognition (MECOR) Score value. In conclusion, our model could provide a simple, rapid, and cheap tool for prompt COVID-19 diagnostic triage in patients with CAP. The actual effectiveness should be evaluated in further, prospective studies also involving COVID-19 patients with negative nasopharyngeal swabs.

Abstract
Fosfomycin is being increasingly prescribed for multidrug-resistant bacterial infections. In patients with systemic involvement, intravenous fosfomycin is usually administered as a partner drug, as part of an antibiotic regimen. Hence, the knowledge of fosfomycin pharmacodynamic interactions (synergistic, additive, indifferent and antagonistic effect) is fundamental for a proper clinical management of severe bacterial infections. We performed a systematic review to point out fosfomycin’s synergistic properties, when administered with other antibiotics, in order to help clinicians to maximize drug efficacy optimizing its use in clinical practice. Interactions were more frequently additive or indifferent (65.4%). Synergism accounted for 33.7% of total interactions, while antagonism occurred sporadically (0.9%). Clinically significant synergistic interactions were mostly distributed in combination with penicillins (51%), carbapenems (43%), chloramphenicol (39%) and cephalosporins (33%) in Enterobactaerales; with linezolid (74%), tetracyclines (72%) and daptomycin (56%) in Staphylococcus aureus; with chloramphenicol (53%), aminoglycosides (43%) and cephalosporins (36%) against Pseudomonas aeruginosa; with daptomycin (97%) in Enterococcus spp. and with sulbactam (75%) and penicillins (60%) and in Acinetobacter spp. fosfomycin-based antibiotic associations benefit from increase in the bactericidal effect and prevention of antimicrobial resistances. Taken together, the presence of synergistic interactions and the nearly total absence of antagonisms, make fosfomycin a good partner drug in clinical practice.

Abstract
“Antimicrobial stewardship” is a strategy that promotes the responsible use of antimicrobials. The objective of this paper is to focus on consolidated and more recent improvements in clinical strategies that should be adopted in hospitalized patients to ameliorate their infectious diseases’ outcome and to reduce the antibiotic resistance risk through judicious use of antibiotics. We present 13 common clinical scenarios, the respective suggested interventions and the explanations of the supporting evidence, in order to help clinicians in their decision-making process. Strategies including the choice of antibiotic and dose optimization, antibiotic spectrum narrowing (de-escalation), shortening of duration, shift to oral route or outpatient parenteral antibiotic (including elastomeric pumps), and biomarkers are described and discussed.

Abstract
OBJECTIVES The aim of this study was to evaluate the factors that can influence an incomplete viral response (IVR) after acute and early HIV infection (AEHI). METHODS This was a retrospective, observational study including patients with AEHI (Fiebig stages I-V) diagnosed between January 2008 and December 2014 at 20 Italian centres. IVR was defined by: (1) viral blip (51-1000 HIV-1 RNA copies/mL after achievement of < 50 HIV-1 RNA copies/mL); (2) virologic failure [> 1000 copies/mL after achievement of < 200 copies/mL, or ≥ 200 copies/mL after 24 weeks on an antiretroviral therapy (ART)]; (3) suboptimal viral response (> 50 copies/mL after 48 weeks on ART or two consecutive HIV-1 RNA levels with ascending trend during ART). Cox regression analysis was used to calculate the hazard ratios (HRs) and 95% confidence intervals (95% CIs) for IVR. RESULTS In all, 263 patients were studied, 227 (86%) males, with a median [interquartile range (IQR)] age of 38 (30-46) years. During a median follow-up of 13.0 (5.7-31.1) months, 38 (14.4%) had IVR. The presence of central nervous system (CNS) symptoms was linked to a higher risk of IVR (HR = 4.70, 95% CI: 1.56-14.17), while a higher CD4/CD8 cell count ratio (HR = 0.13, 95% CI: 0.03-0.51 for each point increase) and first-line ART with three-drug regimens recommended by current guidelines (HR = 0.40, 95% CI: 0.18-0.91 compared with other regimens including four or five drugs, older drugs or non-standard backbones) were protective against IVR. CONCLUSIONS Patients with lower CD4/CD8 ratio and CNS symptoms could be at a higher risk of IVR after AEHI. The use of recommended ART may be relevant for improving short-term viral efficacy in this group of patients.

Abstract
Background Viral load peak and immune activation occur shortly after exposure during acute or early HIV infection (AEHI). We aimed to define the benefit of early start of antiretroviral treatment (ART) during AEHI in terms of immunological recovery, virological suppression, and treatment discontinuation. Setting Patients diagnosed with AEHI (Fiebig stages I-V) during 2008-2014 from an analysis of 20 Italian centers. Methods This was an observational, retrospective, and multicenter study. We investigated the effect of early ART (defined as initiation within 3 months from AEHI diagnosis) on time to virological suppression, optimal immunological recovery (defined as CD4 count ≥500/µL, CD4 ≥30%, and CD4/CD8 ≥1), and first-line ART regimen discontinuation by Cox regression analysis. Results There were 321 patients with AEHI included in the study (82.9% in Fiebig stage III-V). At diagnosis, the median viral load was 5.67 log10 copies/mL and the median CD4 count was 456 cells/µL. Overall, 70.6% of patients started early ART (median time from HIV diagnosis to ART initiation 12 days, IQR 6-27). Higher baseline viral load and AEHI diagnosis during 2012-2014 were independently associated with early ART. HBV co-infection, baseline CD4/CD8 ≥1, lower baseline HIV-RNA, and AEHI diagnosis in recent years (2012-2014) were independently associated with a shorter time to virological suppression. Early ART emerged as an independent predictor of optimal immunological recovery after adjustment for baseline CD4 (absolute and percentage count) and CD4/CD8 ratio. The only independent predictor of first-line ART discontinuation was an initial ART regimen including > 3 drugs. Conclusions In a large cohort of well-characterized patients with AEHI, we confirmed the beneficial role of early ART on CD4+ T-cell recovery and on rates of CD4/CD8 ratio normalization. Moreover, we recognized baseline CD4/CD8 ratio as an independent factor influencing time to virological response in the setting of AEHI, thus giving new insights into research of immunological markers associated with virological control.

Abstract
Pentraxin 3 (PTX3) is an acute phase protein; its plasmatic levels significantly rise during severe infections. Data on PTX3 levels in cerebrospinal fluid (CSF) of patients with central nervous system (CNS) infections are lacking. We aimed (a) to assess the diagnostic potential of measuring CSF PTX3 levels in patients with CNS infections and (b) to establish CSF PTX3 cutoffs to distinguish between bacterial and aseptic meningoencephalitis (ROC curve). PTX3 levels were measured in CSF from 19 patients admitted to Trieste Hospital, Italy, with CNS infection. A diagnosis of bacterial infection and aseptic meningoencephalitis was made in 7 (37%) and 12 (63%) patients, respectively. Subjects with bacterial infections showed significantly higher PTX3 levels (13.5 vs 1.27 ng/mL in aseptic meningoencephalitis, p = 0.010). We identified two different CSF PTX3 levels cutoffs. (1) The best cutoff to maximise Youden's J was 9.6 ng/mL with a sensitivity, specificity, positive predictive value and negative predictive value (NPV) of 71.4%, 91.4%, 83.3%, 84.6%, respectively. (2) The cutoff with higher NPV (100%) was 3.6 ng/mL; a diagnosis of bacterial infections was obtained in 0% patients with CSF PTX3 levels < 3.6 ng/mL vs 58% of those with CSF PTX3 levels ≥ 3.6 ng/mL (p = 0.017). CSF PTX3 levels are higher in bacterial meningitis than aseptic meningoencephalitis. A cutoff of 3.6 ng/mL of CSF PTX3 has a high NPV and can be used to exclude bacterial CNS infections.

Abstract
Objectives To investigate the long-term safety and efficacy of a treatment switch to dual ART with atazanavir/ritonavir + lamivudine versus continuing a standard regimen with atazanavir/ritonavir + 2NRTI in virologically suppressed patients. Methods ATLAS-M is a 96 week open-label, randomized, non-inferiority (margin -12%) trial enrolling HIV-infected adults on atazanavir/ritonavir + 2NRTI, with stable HIV-RNA <50 copies/mL and CD4 counts >200 cells/mm3. At baseline, patients were randomized 1:1 to switch to atazanavir/ritonavir + lamivudine or to continue the previous regimen. Here, we report the 96 week efficacy and safety data. The study was registered with ClinicalTrials.gov, number NCT01599364. Results Overall, 266 subjects were enrolled (133 in each arm). At 96 weeks, in the ITT population, patients free of treatment failure totalled 103 (77.4%) with atazanavir/ritonavir + lamivudine and 87 (65.4%) with triple therapy (difference +12.0%, 95% CI +1.2/+22.8, P = 0.030), demonstrating the superiority of dual therapy. Two (1.5%) and 9 (6.8%) virological failures occurred in the dual-therapy arm and the triple-therapy arm, respectively, without development of resistance to any study drug. Clinical adverse events occurred at similar rates in both arms. A higher frequency of grade 3-4 hyperbilirubinemia (66.9% versus 50.4%, P = 0.006) and hypertriglyceridaemia (6.8% versus 1.5%, P = 0.031) occurred with dual therapy, although this never led to treatment discontinuation. A significant improvement in renal function and lumbar spine bone mineral density occurred in the dual-therapy arm. The evolution of CD4, HIV-DNA levels and neurocognitive performance was similar in both arms. Conclusions In this randomized study, a treatment switch to atazanavir/ritonavir + lamivudine was superior over the continuation of atazanavir/ritonavir + 2NRTI in virologically suppressed patients, with a sustained benefit in terms of improved renal function and bone mineral density.

Abstract
Background: HIV-induced systemic immune activation and inflammation have been associated with morbidity and mortality in virologically suppressed patients. Objective: To evaluate the impact of treatment switch from a dual regimen with lamivudine (3TC) plus ritonavir-boosted protease inhibitors (PI/r) to 3TC plus dolutegravir (DTG) on the monocyte activation marker soluble CD14 (sCD14) and other inflammatory biomarkers, interleukin-6 (IL-6), C-reactive protein (CRP), intestinal fatty acid-binding protein (I-FABP) and D-dimer. Methods: We performed a retrospective case-crossover study on integrase inhibitors-naïve virologically suppressed patients while on 3TC + PI/r dual maintenance therapy for ≥48 weeks who switched to 3TC + DTG and maintained this regimen for ≥48 weeks. Biomarkers plasma levels were tested by ELISA assays on stored samples at three time points: at switch (BL), 48 weeks before (-48 W) and 48 weeks after switch (+48 W). Results: A total of 67 patients were included. Median sCD14 levels were stable from -48 W to BL (from 6.07 to 6.04 log10 pg/mL, p = 0.235) but showed a statistically significant decrease after switch: from 6.04 (IQR 5.92-6.12) at BL to 5.95 (IQR 5.84-6.07) log10 pg/mL at + W48 (p < 0.001). Concurrently, an improvement in lipid profile was observed, even thought it was not correlated to the change in sCD14. The levels of IL-6, CRP, I-FABP and D-dimer remained stable before and after the switch to 3TC + DTG. Conclusions: In virologically suppressed HIV-infected patients on a 3TC + PI/r dual therapy, switching to 3TC + DTG was associated with a significant decline in sCD14. These data suggest reduced monocyte activation following substitution of boosted PI with DTG, which could have important clinical implications.

Abstract
Both cognitive diseases and alexithymia may be associated with HIV. Moreover, alexithymia has been linked to cardiovascular (CV) diseases. Our aim was to explore the prevalence of alexithymia and its associations with neurocognitive disorders (HAND) and CV risk factors in a well-controlled HIV-positive population. We consecutively enrolled 140 HIV-positive individuals on antiretroviral therapy and 35 healthy subjects matched for age, education and gender. In all participants alexithymia was explored by the 20-item Toronto Alexithymia Scale. For HIV-positive subjects also data about CV risk factors were collected, and a comprehensive neuropsychological examination was administered; HAND was defined according to Frascati criteria. Patients and controls did not differ in the proportion of alexithymic status (10% vs. 11%; p=0.761). Among HIV-positive patients, alexithymic participants presented a higher prevalence of diabetes (21% vs. 3%, p=0.035) and hypertension (36% vs. 13%, p= 0.037) compared to non-alexithymic. About 30% (n=41) of HIV-positive patients met criteria for asymptomatic HAND. Alexithymia was not independently associated with a higher risk of HAND (p=0.189). Analyzing each cognitive domain, alexithymia showed an independent association with an abnormal performance (OR 1.08; p=0.037) only in psychomotor speed. In conclusion, in the context of a well-controlled HIV infection, we found a low prevalence of alexithymia comparable to healthy controls. Alexithymia was linked to higher risk of CV disease in the HIV-positive population, but with a rate similar to that previously estimated in the HIV-negative alexithymic. Finally, alexithymia was clearly associated to cognitive impairment only in the psychomotor speed domain, suggesting a common fronto-striatal system dysregulation.

Abstract
The contribution of HCV-related variables to cognitive impairment in HIV-HCV-coinfected patients has been poorly investigated. We selected HIV-HCV-coinfected patients undergoing cognitive examination (exploring memory, language, speed of mental processing and fine motor function) at three clinical centres. Cognitive performance was evaluated using Z-transformed scores. Logistic regression analysis was used to investigate variables associated to cognitive impairment (defined as a composite Z-score ≤ - 1). Overall, 146 HIV-HCV-coinfected patients were enrolled. Median HCV-RNA was 6.2logU/mL. HCV genotype 1a/b was the most represented (53.4%). Liver fibrosis was mild (Fib4 ≤ 1.45) in the majority of patients (44.5%). Global cognitive impairment was diagnosed in 35 (24%) subjects. Exploring each domain, a higher proportion of impairment was observed for memory (37%) followed by speed of mental processing (32.2%), fine motor functioning (24%) and language (18.5%). Among HCV-related variables, the duration of HCV infection was independently associated with global cognitive impairment (aOR 1.13 per +1 year, p = 0.016) and abnormal speed of mental processing (aOR 1.16 per +1 year, p = 0.001), while higher HCV-RNA was independently associated to fine motor functioning impairment (aOR 1.98 per +1log, p = 0.037). HCV genotype, fibrosis stage, transaminases or bilirubin levels were not related to cognitive performance. Of note, integrase inhibitor (InSTI) use was independently associated to a pathological performance in fine motor functioning (aOR 3.34, p = 0.035) and memory (aOR 3.70, p = 0.014). In conclusion, the duration of HCV infection and HCV-RNA load showed an association with cognitive impairment, suggesting a role of hepatitis-related factors in the development of cognitive disorders in HIV-HCV-coinfected patients. The association between InSTI use and altered cognitive performance should prompt investigations about potential neurotoxicity of these drugs.

Abstract
To assess the impact of genotypic susceptibility score (GSS) on combined antiretroviral therapy (cART) outcomes during primary HIV infection (PHI) we retrospectively enrolled patients with PHI diagnosed between 2008 and 2015 at 9/24 Italian Network ACuTe HIV InfectiON centers. One hundred-seventy-six patients were enrolled. Of these, 55 (32.9%) patients started with more than three drugs and 11 (7.2%) started with a GSS < 3. Regimen's GSS (per 1 point increase) (adjusted odds ratio [aOR], 4.82; 95% confidence interval [CI], 1.62-14.28; P = .005) and baseline HIV-RNA (per 1 log10 increase) (aOR, 2.02; 95% CI, 1.09-3.73; P = .025) resulted associated with early cART initiation. In conclusion, regimen's GSS resulted to be associated to the time to cART initiation during PHI.
