    Abstract The role of different genotypes in nucleos(t)ide analogs (NAs) treatment is still debated. Previous studies conducted on special populations evidenced that the E genotype had the lower virological and serological response. This descriptive study aims to recognize the hepatitis B "s" antigen (HBsAg) decline during tenofovir disoproxil fumarate (TDF) treatment in a cohort of patient affected by chronic hepatitis B (CHB). We retrospectively included all patients with CHB treated with TDF between April 2007 and March 2012 with a duration of treatment of 7 years. Kinetics of HBsAg was determined as serological response in this cohort. We include 110 subjects; virological response was observed in all subjects with genotypes A, B, and D; in 17 patients with C genotype (94.4%) and 24 with E genotype (96%). HBeAg loss was observed in 2 patients with genotype A (50%), 3 with B (100%), 0 with C (0%), 1 with D (20%), and 1 with E genotype (25%). In multivariate analysis we observed as predictive factors of HBsAg decline the baseline level of HBsAg (OR = 1.467; 95%CI: 1.221-5.113;

    Abstract Background: Blood brain barrier impairment is frequent in people living with HIV (PLWH), affecting the penetration of target cells and antiretrovirals into the central nervous system, through transporters (e.g. ABCB1), leading to neuroinflammation.
    Objectives: The aim of this study was to identify variants of genes encoding transporters able to predict neuroinflammation biomarker levels.
    Materials and methods: Cerebrospinal fluid (CSF) and plasma samples were obtained from PLWH. CSF biomarkers were quantified by commercial assays. Genetic variants were evaluated through real-time polymerase chain reaction (PCR).
    Results: 107 PLWH (163 samples) were included in the study: 79% were male, median age was 48.5 years, CD4% was 25%, HIV-associated neurolocognitive disorder (HAND) was observed in 17.8% of patients. ABCB1 2677G>T genetic variant showed a different allelic distribution according to the clinical group (p=0.026). In linear regression analyses, HIV-related central nervous system disorders, ABCG2 1194+928CC genotype, log viral load, CSAR, β-1,42 levels and CSF proteins were retained in the final model as factors independently associated with CSF neopterin levels; CSF proteins and integrase inhibitors use were associated with CSF tau level in the multivariate model. Phospho-tau regression analysis reported ABCB1 2677GT/TT genotype and CSF proteins as predictors in the final model; gender and protease inhibitors, neopterin, ABCB1 2677 GT/ TT genotype resulted predictors in the multivariate regression for β-1,42.
    Conclusions: For the first time, pharmacogenetic and clinical features were predictors of neuro-inflammation biomarkers.

    Abstract Background: Low-level HIV viremia originating from virus reactivation in HIV reservoirs is often present in cART treated individuals and represents a persisting source of immune stimulation associated with sub-optimal recovery of CD4
    Methods: Volunteers enrolled in a 3-year longitudinal observational study were stratified by residual viremia, Tat serostatus and frequency of anti-Tat cellular immune responses. The impact of anti-Tat immunity on low-level viremia, persistent immune activation and CD4
    Findings: Anti-Tat immunity is significantly associated with higher nadir CD4
    Interpretation: Therapeutic approaches aiming at reinforcing anti-Tat immunity should be investigated to improve immune reconstitution in people living with HIV on long-term cART.

    Abstract Drug bioavailability may vary greatly amongst individuals, affecting both efficacy and toxicity: in humans, genetic variations account for a relevant proportion of such variability. In the last decade the use of pharmacogenetics in clinical practice, as a tool to individualize treatment, has shown a different degree of diffusion in various clinical fields. In the field of infectious diseases, several studies identified a great number of associations between host genetic polymorphisms and responses to antiretroviral therapy. For example, in patients treated with abacavir the screening for HLA-B*5701 before starting treatment is routine clinical practice and standard of care for all patients; efavirenz plasma levels are influenced by single nucleotide polymorphism (SNP) CYP2B6-516G>T (rs3745274). Regarding antibiotics, many studies investigated drug transporters involved in antibiotic bioavailability, especially for fluoroquinolones, cephalosporins, and antituberculars. To date, few data are available about pharmacogenetics of recently developed antibiotics such as tigecycline, daptomycin or linezolid. Considering the effect of SNPs in gene coding for proteins involved in antibiotics bioavailability, few data have been published. Increasing knowledge in the field of antibiotic pharmacogenetics could be useful to explain the high drug inter-patients variability and to individualize therapy. In this paper we reported an overview of pharmacokinetics, pharmacodynamics, and pharmacogenetics of antibiotics to underline the importance of an integrated approach in choosing the right dosage in clinical practice.

    Abstract We evaluated ethambutol plasma and intracellular pharmacokinetic according to single nucleotide polymorphisms in ABCB1, OATP1B1, PXR, VDR, CYP24A1 and CYP27B1 genes. Mycobacterium tubercolosis infected patients were enrolled. Standard weight-adjusted antitubercular treatment was administered intravenously for 2 weeks and then orally. Allelic discrimination was performed by real-time PCR. Ethambutol plasma and intracellular concentrations were measured by UPLC-MS/MS methods. Twenty-four patients were included. Considering weeks 2 and 4, median plasma Ctrough were 73 ng/mL and 247 ng/mL, intracellular Ctrough were 16,863 ng/mL and 13,535 ng/mL, plasma Cmax were 5627 ng/mL and 2229 ng/mL, intracellular Cmax were 133,830 ng/mL and 78,544 ng/mL. At week 2, ABCB1 3435 CT/TT (p=0.023) and CYP24A1 8620 AG/GG (p=0.030) genotypes for plasma Ctrough, BsmI AA (p=0.036) for intracellular Ctrough and BsmI AA (p<0.001) and ApaI AA (p=0.048) for intracellular Cmax, remained in linear regression analysis as predictive factors. Concerning week 4 only ABCB1 3435 CT/TT (p=0.035) and Cdx2 AG/GG (p=0.004) genotypes for plasma Ctrough and BsmI AA (p=0.028) for plasma Cmax were retained in final regression model. We reveal, for the first time, the possible role of single nucleotide polymorphisms on ethambutol plasma and intracellular concentrations; this may further the potential use of pharmacogenetic for tailoring antitubercular treatment.
