Abstract
This study evaluates the frequency and causes of dolutegravir (DTG) discontinuation along 5 years of follow-up, in both antiretroviral treatment (ART)-naive and experienced people living with HIV (PLWH). This is a prospective multi-center cohort study enrolling PLWH on DTG from July 2014 until November 2020. DTG-durability was investigated using the Kaplan-Meier survival curve. The Cox proportional-hazards model was used for estimating the hazard ratio (HR) of DTG discontinuation for any cause, and for adverse events (AEs). Nine hundred sixty-three PLWH were included, 25.3% were women and 28.0% were ART-naive. Discontinuations for any causes were 10.1 [95% confidence interval (95% CI) 8.9-11.5] per 100 person-years, similar in most regimens, with the apparent exception of tenofovir alafenamide/emtricitabine+DTG (p < 0.0001). In the multivariable Cox regression model, non-Caucasian ethnicity, age ≥50 years, and lower estimated glomerular filtration rate (eGFR) were associated with a higher probability of DTG interruption. The incidence rate of virological failure was 0.4 (95% CI 0.2-0.7) per 100 person-years, while the estimated discontinuation rate for AEs was 4.0 (3.2-4.9) per 100 person-years. Thirty-four DTG interruptions were due to grade ≥3 events (10 central nervous system, 6 hypersensitivity, 3 renal, 3 myalgia/asthenia, 3 abdominal pain, 2 gastrointestinal, and 7 other events). People with lower body mass index, age ≥50 years, and lower eGFR were at higher risk of AEs, while dual combinations were protective (HR 0.41 compared with abacavir/lamivudine/DTG, 95% CI 0.22-0.77). In this prospective observational study, we found high DTG durability and a low rate of virological failures. Dual therapies seemed protective toward AEs and might be considered, when feasible, a suitable option to minimize drug interactions and improve tolerability.

Abstract
Background The spectrum of COVID-19 clinical manifestations is not yet known. In the elderly, mortality and extrapulmonary involvement appears more frequent than expected. Methods A multicentre-retrospective-case-series study of COVID-19 patients, aged ≥65 years, hospitalised between March 1 and June 15, 2020. Patients were classified at admission into 3 groups based on their Clinical Frailty Scale (CFS) score: 1–3 (group A), 4–6 (group B) and 7–9 (group C). Results Of the 206 patients in the study, 60 (29%) were assigned to group A, 60 (29%) to B and 86 (42%) to C. Significantly more frequent in group C than in B or A were: mental confusion (respectively 65%, 33%, 7%; P < 0.001), kidney failure (39%, 22%, 20%; P = 0.019), dehydration syndrome (55%, 27%, 13%; P < 0.001), electrolyte imbalance (54%, 32%, 25%; P = 0.001), and diabetic decompensation (22%, 12%, 7%; P = 0.026). Crude mortality was 27%. By multivariate logistic regression model independent predictors of death were male sex (adjusted odds ratio (aOR) = 2.87,95%CI = 1.15–7.18), CFS 7–9 (aOR = 9.97,95%CI = 1.82–52.99), dehydration at admission (aOR = 4.27,95%CI = 1.72–10.57) and non-invasive/invasive ventilation (aOR = 4.88,95%CI = 1.94–12.26). Conclusions Elderly patients with a high CFS showed frequent extrapulmonary signs at admission, even in the absence of lung involvement. These findings, along with a high CFS, predicted a significant risk of mortality.

Abstract
OBJECTIVE To optimize the management of patients with chronic hepatitis C virus (HCV). MATERIALS AND METHODS We developed two questionnaires to determine Italian healthcare professionals' opinions on the overall management of HCV chronic liver disease and the use of direct-acting antivirals (DAAs) in the treatment of HCV. A Delphi consensus method using the RAND/UCLA appropriateness method was used to determine opinions of an expert panel (EP) of specialists. RESULTS Overall 443 physicians from 167 Italian centres completed the two questionnaires. The EP confirmed the importance of collaboration with general practitioners (GPs) and HCV testing in high-risk groups, but did not agree on treating patients over 80 years of age with DAAs. Over 90% agreed that it was important to quantify HCV-RNA, determine genotype, and test for anti-HIV and HBsAg before starting DAAs. Transient elastography (FibroScan®) was used by >90% to evaluate the stage of liver fibrosis while serum biomarkers were used by <20%. Adherence to therapy, drug-drug interactions and the possibility of treating advanced liver disease were decisive factors in therapy choice. Monthly monitoring during therapy was considered appropriate and 80% were in favor of HCV-RNA testing 24 weeks after the end of the therapy to confirm sustained virological response (SVR). Over 80% agreed that it was necessary to continue follow-up of patients with advanced fibrosis/cirrhosis. CONCLUSIONS Scientific organizations should review their guideline recommendations to facilitate access to DAAs.

Abstract
Background Splenic nodules are uncommon entities that occur rarely in the general population. Although an infectious etiology (primarily bacteria, followed by mycobacteria) is usually found, noninfectious diseases, including malignancies and autoimmune disorders, can also be involved. For instance, in course of inflammatory bowel diseases (IBDs), in particular Crohn’s Disease, aseptic splenic abscesses have been reported in patients with a long history of illness, or in those unresponsive to medical treatments, while are only anecdotally reported in the early phase of the disease. Hence, we presented the case of aseptic splenic nodules as a first manifestation of Crohn’s Disease. Case presentation A 21-year-old woman with a silent medical history was admitted to the Emergency Department of our hospital complaining of fever of 38–39 °C (mainly in the evening) for the past 10 days and left flank abdominal pain, accompanied by sweating and fatigue. An abdominal computed tomography showed multiple splenic nodules of unknown origin. Because of the absence of clinical improvement after several antibiotic therapiesand a positron emission tomography (PET) with hypercaptation strictly localized to spleen, she underwent splenectomy, in suspicion of lymphoma. For persistence of symptoms after splenectomy, she underwent many instrumental examination, including a colonoscopy with bowel and intestinal biopsies that poses diagnosis of Crohn’s disease. A second PET confirmed this diagnosis showing this time also the gastrointestinal involvement. Conclusion An unusual onset of Crohn’s disease with multiple splenic nodules is reported. This case suggests that in light of splenic nodules of unknown etiology attention should be paid to all possible diagnoses of aseptic abscesses, including IBDs (primarily Crohn’s Disease).

Abstract
PURPOSE We aimed to evaluate HIV-1 compartmentalization between the cerebrospinal fluid (CSF) and plasma and investigate as to which extent HIV-1 strains in CSF differ from those in blood and whether a correlation with either plasma viral load (pVL) or an altered blood-brain barrier (BBB) does exist. STUDY DESIGN We retrospectively evaluated paired CSF/blood samples collected from 86 HIV+ patients. HIV-RNA quantification, pol (PR/RT), and V3 sequencing were performed. HIV coreceptor tropism (CRT) was inferred (g2p, false-positive rate 10%, FPR). Data of standard CSF analysis were also reviewed; an altered CSF/plasma albumin ratio signified BBB damage. Neurological abnormalities (NA) were recorded. RESULTS Overall, 32% of patients had a CSF/plasma HIV-RNA ratio > 1 (discordance); 3% of patients had detectable CSF HIV-RNA despite suppressed pVL (escape). Discordance was more frequent in ART-treated patients (p < 0.001) and in patients with NA (p = 0.016), but was independent of BBB damage (p = 0.65) and AIDS diagnosis (p = 0.96). Finally, CSF/plasma discordance was significantly more frequent (p < 0.0001) in patients with lower pVL values (< 10.000 copies/ml). Env divergence > 10% was found in 44% of sequences and was associated with ART (p = 0.008) and NA (p = 0.037). Overall, 24% of patients had a discordant CSF/blood CRT. A 100% nucleotide identity was observed in only 7.3% of pol sequences; notably, 10% of patients had resistance-associated mutations in CSF, but not in blood. CONCLUSIONS Our data confirm an independent replication and evolution of HIV within the CSF. A number of factors either hinder or contribute to the compartmentalization of HIV.

Abstract
The possibility of the non-parenteral Hepatitis C Virus (HCV) transmission is supported by the demonstration that the actual virus is present in several body fluids, including saliva. From a review of the literature many investigators have found the presence of HCV-RNA in saliva, however, widely contrasting results emerge, with detection rates ranging from 0–100%. To further examine HCV salivary shedding, saliva samples were collected from 46 chronically HCV-infected patients and tested for HCV-RNA and occult blood. Quantification and genotyping of serum HCV-RNA were also carried out for each patient. HCV-RNA was detected in 39.13% of the saliva samples. The viral salivary shedding was significantly related to viraemia levels, serum viral genotype and the presence of salivary occult blood. Our findings indicate that the HCV salivary shedding occurs in about one third of HCV-infected patients, but seem to suggest that it is unlikely when the serum viral genotype is 3a. Moreover, blood leakage into the oral cavity is possibly the main source of the salivary HCV-RNA. Although the occurrence of the viral salivary shedding does not necessarily mean that HCV trasmission occurs by saliva, our results suggest the need for further investigations into the biological factors possibly involved in HCV mucosal transmission related to both the source and the exposed subjects.

Abstract
OBJECTIVES We assessed whether changes in community viral load (CVL) over time were associated with the rate of new HIV diagnoses (NDs). METHODS HIV-1-positive individuals referred to our institute and permanently residing in our province were considered for inclusion in the study. A total of 861 HIV-infected adults with at least one HIV RNA measurement (12 530 measurements in total) between 2008 and 2014 were included. Viraemia copy-years were calculated from all HIV RNA values for each patient using the trapezoidal rule; multiple CVL indicators were considered. Total NDs and recent infections (< 1 year) were analysed separately. The association between NDs and CVL was tested by means of mixed Poisson models, with CVL as a fixed effect and year as a random effect. RESULTS The incidence of NDs was 2.28 per 100 000 residents in 2008 and 2.52 per 100 000 residents in 2014. Total numbers of NDs and recent infections did not vary significantly over time (P for trend 0.879 and 0.39, respectively). Mean HIV RNA decreased from 31 095.8 HIV-1 RNA copies/mL in 2008 to 21 231.5 copies/mL in 2014 (P < 0.001); a downward trend was always observed regardless of the CVL indicator considered. Depending on the indicator, there were some differences in CVL by patient characteristics. The most substantial contributors to CVL appeared to be male individuals, men who have sex with men (MSM), non-Italians, and untreated subjects (all P < 0.05). The relative risk of ND increased among Italians and MSM with an increasing proportion of subjects having an undetectable HIV RNA, and decreased in the same population with increasing levels of CVL. CONCLUSIONS In our setting, CVL represented a good marker of access to care and treatment; however, reduced CVL did not coincide with a reduction in the rate of NDs.

Abstract
To compare clinical characteristics and therapeutic management of newly HIV-diagnosed immigrants to natives. Patients with a first HIV diagnosis from 1996 to 2010 were included. Of 716 new diagnoses, 85 (12 %) were immigrants. Migrants were younger, more frequently females and sexually infected, less likely to voluntarily request testing, and less HCV-coinfected. Late presenters (CD4 <350 or AIDS) were 76 % among migrants versus 56 % in natives (p = 0.006) with an increasing trend over time. HAART was initiated in 76.5 % of natives and 72.4 % of immigrants; the number/type of adverse events and treatment discontinuation were similar. Immigrants received more NNRTIs-based regimens. A similar proportion of patients reached virological suppression at month 1-3-6 after HAART initiation, but 43 % of immigrants versus 27 % of natives resulted lost to follow-up (p < 0.001). Diagnosis of HIV was often delayed among migrants, who also presented a higher rate of lost to follow-up.

Abstract
BACKGROUND In HIV-HCV co-infected patients, the long-term effects of HCV eradication on HIV disease progression are still unclear. OBJECTIVES This study aims to determine if CD4 and CD4/CD8 ratio slopes improved after anti-HCV treatment in patients achieving a sustained virological response (SVR). STUDY DESIGN A total of 116 HIV-HCV co-infected patients, previously treated with Peg-IFN/RBV, were divided into two groups: SVR (55 patients who had achieved SVR), and non-SVR (61 patients). Retrospective data before and after anti-HCV therapy were obtained for all patients, with a median 8 year-follow-up. Multilevel mixed models were fitted to assess the trends over time of FIB-4 score, APRI score, CD4, CD8 cell count and CD4/CD8 ratio. RESULTS Median HIV-infection duration, HCV-RNA and GGT baseline levels were higher in non-SVR compared to the SVR group. A significantly decreased FIB-4 (p<0.001) and APRI trend (p<0.001) after SVR was observed in SVR patients compared to those non-SVR. After adjustment for HIV duration, there was no significant difference between the two groups for absolute CD4 (p=0.08) or percentage CD4 slope (p=0.6) over time. The CD4/CD8 ratio trend also demonstrated a similar progressive increase in both groups (p=0.2). During follow-up, six deaths were reported in the non-SVR group versus no death for the SVR group, while no difference in AIDS and non-AIDS events was observed. CONCLUSIONS Achievement of SVR determines an important beneficial impact in terms of liver-related mortality and fibrosis regression, but does not seem to alter neither the slope of long term CD4 gain nor the CD4/CD8 ratio evolution in ART-treated HIV-HCV co-infected patients.

Abstract
Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors. Background. Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes. The SPREAD program systematically collects data to gain insight into TDR occurring in Europe since 2001. Methods. Demographic, clinical, and virological data from 4140 antiretroviral-naive human immunodeficiency virus (HIV)–infected individuals from 26 countries who were newly diagnosed between 2008 and 2010 were analyzed. Evidence of TDR was defined using the WHO list for surveillance of drug resistance mutations. Prevalence of TDR was assessed over time by comparing the results to SPREAD data from 2002 to 2007. Baseline susceptibility to antiretroviral drugs was predicted using the Stanford HIVdb program version 7.0. Results. The overall prevalence of TDR did not change significantly over time and was 8.3% (95% confidence interval, 7.2%–9.5%) in 2008–2010. The most frequent indicators of TDR were nucleoside reverse transcriptase inhibitor (NRTI) mutations (4.5%), followed by nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.9%) and protease inhibitor mutations (2.0%). Baseline mutations were most predictive of reduced susceptibility to initial NNRTI-based regimens: 4.5% and 6.5% of patient isolates were predicted to have resistance to regimens containing efavirenz or rilpivirine, respectively, independent of current NRTI backbones. Conclusions. Although TDR was highest for NRTIs, the impact of baseline drug resistance patterns on susceptibility was largest for NNRTIs. The prevalence of TDR assessed by epidemiological surveys does not clearly indicate to what degree susceptibility to different drug classes is affected.

Abstract
PURPOSE To develop recommendations for the management of acute hepatitis B by the Italian Society for the Study of Infectious and Tropical Diseases. METHODS Development of the recommendations divided into three levels of evidence according to the GRADE system: A (high), B (medium) and C (low experts opinion), together with three recommendation levels: 1 (strong), 2 (medium), 3 (weak). RESULTS The treatment with antivirals is in selected cases the mainstay of management of severe acute hepatitis, and should be started as a matter of urgency in order to prevent death. CONCLUSIONS These recommendations are meant to provide the rationale and practical indications for the management of acute hepatitis B (AHB).

Abstract
BACKGROUND In HIV/HCV co-infected patients, HIV-1 gp120 activates human hepatic stellate cells (HSCs) which play a key role in fibrosis pathogenesis. It is still unclear whether pro-fibrogenic effects are more attributable to X4 or R5 strains in vivo. OBJECTIVE To assess if HIV-1 X4 or R5 variants are associated with a different progression of fibrosis. STUDY DESIGN A total of 105 HIV/HCV co-infected patients were submitted to gp120 sequencing on proviral DNA and classified as X4 or R5 based on g2p (20% false positive rate). The fibrosis evolution was retrospectively determined by means of APRI and FIB-4 scores at 3-month intervals from the first anti-HCV-positive test. The association of co-receptor tropism with increased fibrosis scores was evaluated by linear mixed models. RESULTS X4 variants were found in 41 patients (39%). The median observation period was similar in X4 and R5 patients (17 years). No difference was observed between the two groups of patients, except for nadir CD4 which was lower in X4 compared to R5 (percentage, p=0.005, and absolute number, p=0.005). X4 and R5 patients did not significantly differ for FIB-4 and APRI score over time (p=0.5, and p=0.1, respectively). No association between HCV-RNA levels over time and co-receptor tropism was noted (p=0.9). Conversely, a significant correlation of fibrosis scores with gamma-glutamyl transferase levels, lower current CD4 count, HIV viremia and use of antiretrovirals was observed. CONCLUSIONS This retrospective analysis of fibrosis evolution did not support the evidence of a differing pro-fibrogenic activity for X4 and R5 HIV-1 variants in HIV/HCV co-infected patients.

Abstract
PURPOSE We have developed a sequencing assay for determining the usage of the genotypic HIV-1 co-receptor using peripheral blood mononuclear cell (PBMC) DNA in virologically suppressed HIV-1 infected patients. Our specific aims were to (1) evaluate the efficiency of V3 sequences in B versus non-B subtypes, (2) compare the efficiency of V3 sequences and tropism prediction using whole blood and PBMCs for DNA extraction, (3) compare the efficiency of V3 sequences and tropism prediction using a single versus a triplicate round of amplification. RESULTS The overall rate of successful V3 sequences ranged from 100 % in samples with >3,000 copies HIV-1 DNA/10(6) PBMCs to 60 % in samples with <100 copies total HIV-1 DNA /10(6) PBMCs. Analysis of 143 paired PBMCs and whole-blood samples showed successful V3 sequences rates of 77.6 % for PBMCs and 83.9 % for whole blood. These rates are in agreement with the tropism prediction obtained using the geno2pheno co-receptor algorithm, namely, 92.1 % with a false-positive rate (FPR) of 10 or 20 % and of 96.5 % with an FPR of 5.75 %. The agreement between tropism prediction values using single versus triplicate amplification was 98.2 % (56/57) of patients using an FPR of 20 % and 92.9 % (53/57) using an FPR of 10 or 5.75 %. For 63.0 % (36/57) of patients, the FPR obtained via the single amplification procedure was superimposable to all three FPRs obtained by triplicate amplification. CONCLUSIONS Our results show the feasibility and consistency of genotypic testing on HIV-1 DNA tropism, supporting its possible use for selecting patients with suppressed plasma HIV-1 RNA as candidates for CCR5-antagonist treatment. The high agreement between tropism prediction by single and triple amplification does not support the use of triplicate amplification in clinical practice.

Abstract
BACKGROUND The continuing migration of individuals from geographic areas with high/medium endemicity has determined the arrival of new chronic hepatitis B virus (HBV) carriers in Italy. The magnitude of this phenomenon and clinical/virological features of HBsAg-positive migrants remain not very well defined. AIMS To evaluate the proportion of HBsAg-positive immigrants enrolled in this multicenter Società Italiana di Malattie Infettive e Tropicali (SIMIT) cross-sectional study and to compare the characteristics of chronic hepatitis B infection in migrants to those of Italian carriers. METHODS From February 1 to July 31 2008, anonymous data were obtained from all HBsAg-positive patients aged ≥ 18 years observed at 74 Italian centers of infectious diseases. RESULTS Of the 3,760 HBsAg-positive subjects enrolled, 932 (24.8 %) were immigrants, with a prevalent distribution in central to northern Italy. The areas of origin were: Far East (37.1 %), Eastern Europe (35.4 %), Sub-Saharan Africa (17.5 %), North Africa (5.5 %), and 4.5 % from various other sites. Compared to Italian carriers, migrants were significantly younger (median age 34 vs. 52 years), predominantly female (57.5 vs. 31 %), and most often at first observation (incident cases 34.2 vs. 13.3 %). HBeAg-positives were more frequent among migrants (27.5 vs. 14 %). Genotype D, found in 87.8 % of Italian carriers, was present in only 40 % of migrants, who were more frequently inactive HBV carriers, with a lower prevalence of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Only 27.1 % of migrants received antiviral treatment compared to 50.3 % of Italians. CONCLUSIONS Twenty-five percent of all HBV carriers examined at Italian centers was composed of immigrants with demographic, serological, and virological characteristics that differed from those of natives and appeared to have an inferior access to treatment.

Abstract
A multicentre cross-sectional survey was performed to provide an accurate picture of patients with chronic hepatitis B (CHB) cared for by Italian Infectious Diseases Centers (IDCs). This analysis describes factors associated with access to the treatment of CHB in a country where barriers to treatment are not expected to exist because of comprehensive coverage under the National Health System (NHS). The study was performed in 74 IDCs. The analysis focused on 3305 patients with CHB of 3760 HBsAg-positive patients enrolled from March to September, 2008. To account for missing values, a Multiple Imputation method was used. Treatment was reported in 2091 (63.3%) patients. In the multivariate analysis, an increased chance of getting treatment was independently associated with 10 years increase of age at diagnosis (adjusted odds ratio [aOR] 1.2, 95% confidence interval [CI] 1.1-1.3, P < 0.001), HBeAg positivity (aOR 1.8, 95% CI 1.1-2.8, P < 0.001), cirrhosis (aOR 3.6, 95% CI 2-6.3, P = 0.012), HDV (aOR 1.6, 95% CI 1.02-2.5, P = 0.042) and HIV positivity (aOR 6.5, 95% CI 4-10.8, P < 0.001). Conversely, a decreased chance was associated with female gender (aOR 0.6, 95% CI 0.5-0.7, P < 0.001), immigration (aOR 0.6, 95% CI 0.5-0.9, P = 0.009), alcohol consumption (aOR 0.7, 95% CI 0.5-0.98, P = 0.04) and HCV positivity (aOR 0.5, 95% CI 0.3-0.8, P = 0.005). Our study shows that Italian IDCs treat a high percentage of patients with CHB. Nevertheless, disparities exist which are not related to the severity of disease limiting access to antiviral therapy of CHB, even in a country with a universal healthcare system.

Abstract
The combination of pegylated interferon (Peg-IFN) and ribavirin is currently the gold standard therapy in patients with HCV chronic infection. The duration of therapy, as well as the therapeutic dosage, depend on the genotype. Identification of the genotype and rapid virological response (RVR) are widely accepted as the most important predictors of clinical outcome during antiviral therapy but to optimize cost-benefits and to reduce possible side effects, further prognostic factors are needed. Squamous cell carcinoma antigens immunocomplex (SCCA-IC) has been reported to be increased in the serum of patients with liver cancer. In this multicentric prospective study, we investigated the serum levels of SCCA-IC in 103 patients with HCV chronic infection. Serum HCV-RNA was detected before the beginning of treatment, after 4, 12, 24 or 48 weeks, and at week 24 during follow-up. RVR, early virological response and sustained virological response (SVR) were assessed following the international guidelines. SCCA-IC levels were higher in responders (238 AU, interquartile difference 130-556 AU) and decreased significantly to 125 AU (70-290 AU). The mean baseline value in nonresponders was 149 AU (86.5-306.5 AU), but after 4 weeks of treatment the serum levels decreased to 115 AU (80-280 AU): the profile of reduction was different between patients with or without a positive SVR. Logistic regression with SVR as dependent variable identified as significant independent variables: the reduction in SCCA-IC after 1 month (OR = 4.82; 95% CI 1.39-16.67; P = 0.131) and a genotype other than 1 (OR = 0.094; 95% CI 0.21-0.42; P = 0.002); sex and age were also significant factors influencing SVR. SCCA-IC seems to be a reliable independent prognostic marker of therapeutic effectiveness in anti-HCV positive patients undergoing antiviral therapy.

Abstract
Through this study we evaluated whether the HIV-1 tropism determined by genotypic analysis correlates with HIV-1 markers, such as CD4 cell count and plasma HIV-RNA. The analysis was performed on 1221 HIV-1 B-subtype infected patients with an available V3 sequence (all maraviroc naive). Of them, 532 were antiretroviral therapy (ART) naive and 689 ART experienced. Tropism determination was performed by using the geno2pheno (co-receptor) algorithm set at a false-positive rate (FPR) of 10% and 2%. Potential associations of FPR with CD4 cell count and viraemia were evaluated. Association of V3 mutations with genotypic-determined tropism was also evaluated according to different FPR ranges. About 26% of patients (either ART naive or ART experienced) were infected by X4-tropic viruses (using the classical 10% FPR cut-off). However, a significantly lower proportion of ART-naive patients had FPR ≤ 2% in comparison with ART-experienced patients (4.9% vs. 12.6%, respectively, p <0.001). The risk of advanced HIV-1 infection (with CD4 cell count ≤ 200 cells/mm(3)) was significantly greater in X4-infected patients, either ART-naive (OR (95% CI)), 4.2 (1.8-9.2); p 0.0006) or ART-experienced (2.3 (1.4-3.6); p 0.0003), with FPR set at 2% (but not at 10%). This finding was confirmed by multivariable logistic analysis. No relationship was found between viraemia and FPR ≤2%. Some X4-related mutations were significantly associated with FPR ≤2% (ART-naive patients, S11R, Y21V, G24K and G24R, p ≤0.001; ART-experienced patients, Y7K, S11R, H13Y, p ≤0.002). In conclusion, these findings show that within the context of genotypically-assessed CXCR4 tropism, FPR ≤2% defines (far better than 10%-FPR) a viral population associated with low CD4 rank, with potentially greater cytopathic effect, and with more advanced disease.

Abstract
Cardiac Implantable Electronic Device (CIED) infections are an emerging clinical issue. There are no national recommendations on the management of these infections, also due to the limited number of dedicated and high quality clinical studies. Therefore, researchers from southern Italian centres have decided to share the clinical experience gathered so far in this field and report practical recommendations for the diagnosis and treatment of adult patients with CIED infection or endocarditis. Here we review the risk factors, diagnostic issues (microbiological and echocardiographic) and aetiology, and describe extensively the best therapeutic approach. We also address the management of complications, follow-up after discharge and the prevention of CIED infections. In this regard, a multidisciplinary approach is fundamental to appropriately manage the initial diagnostic process and the comorbidities, to plan proper antimicrobial treatment and complete percutaneous hardware removal, with the key support of microbiology and echocardiography.

Abstract
This study in Italy aimed to evaluate the epidemiological, clinical and therapeutic aspects of hepatitis B virus (HBV) infection in a population of recent (< 6 months) immigrants. Between February 2003 and December 2004, 83 (9.3%) out of 890 immigrants tested positive for hepatitis B surface antigen. All were men and 62.6% came-from Africa, 21.6% from Asia and 16.8% from Eastern Europe. About half (54.3%) of the patients had elevated alanine aminotransferase levels and detectable serum HBV DNA. Genotype distribution was as follows: E (20 cases), D (14 cases) and A (11 cases). Our study underscores the potential of migratory flow to introduce genotype non-D hepatitis B virus into our country.

Abstract
Paired PBMCs and plasma samples from 34 HIV-infected patients were studied to verify the relationship between coreceptor use based on genotyping of V3 region of HIV-1 envelope gp120 and biological phenotype with virus isolation and subsequent correlation to clinical characteristics. The "11/25" rule, geno2pheno and PSSM were compared. All SI patients were HIV-1 subtype B (p=0.04) and had a lower CD4 count than NSI patients (p=0.01), while no differences were observed in mean HIV-RNA (log) (p=0.6). SI phenotype was not associated with AIDS-defining events (p=0.1) or with concurrent antiretroviral therapy (p=0.4). With geno2pheno, which shows the highest sensibility (83%), an X4 or X4/R5 genotype in PBMC DNA was also associated to B-subtype and lower CD4 count (p=0.01) compared to R5 isolates. Based on plasma RNA sequences, the predicted coreceptor usage agreed with PBMC DNA in 79% of cases with the "11/25" rule, 82% with geno2pheno, and 82% with PSSM. A X4 virus in plasma (but not in PBMCs) was significantly associated with HAART in all three methods (p=0.01 for "11/25" rule, p=0.01 for geno2pheno and p=0.03 for PSSM). Due to viral mixtures and/or difficulties in genotype interpretation, current V3 sequence-based methods cannot accurately predict HIV-1 coreceptor use.

Abstract
An extended spectrum of HIV-1 reverse-transcriptase (RT) mutations in HAART-treated patients has been recently described. To verify the possible association of previously unreported RT mutations with a decrease of phenotypic susceptibility to nucleoside (NRTIs) and non-nucleoside (NNRTIs) RT inhibitors, the RT sequence of 328 HIV-1-positive patients (102 naïve and 226 treated with HAART participating in either the PhenGen or Genpherex study) was analyzed. All treated patients were tested at the time of therapeutic failure with both phenotypic (Antivirogram, Virco) and genotypic analyses (VircoGen); the frequency of RT substitutions (positions 1-240) with respect to consensus B was compared to that of naïve patients using a Chi-square test. Amino acid changes at 13 positions not included in the IAS list of resistance-associated mutations were detected more frequently in treated than in naïve subjects. The mutations involving 10 of these positions were associated with a reduced susceptibility to antiretroviral drugs; K20R, T39A, K43EQN, E203KD, H208Y, and D218E were correlated with NRTI resistance while mutations K101EQP, H221Y, K223EQ, L228HR were associated to NNRTI resistance. A correlation was found between K20R and lamivudine resistance (P = 0.006) while T39A (P = 0.005), K43EQN (<0.001), E203KD (P = 0.010), and H208Y (P = < 0.001) seemed to be associated with a previous use of zidovudine and stavudine and with the development of thymidine analog resistance. For H208Y, an association with use/resistance to abacavir (P = 0.004) was also noted. D218E showed a weak association to didanosine resistance (P = 0.013). The data confirm that previously unreported mutations are associated with antiretroviral drug experience and, more importantly, with a reduced susceptibility to NRTIs and NNRTIs.

Abstract
A panel of leading Italian specialists in infectious diseases, virologists and immunologists met in Rome in 2005 to review critical data and discuss recommendations for each of the key questions in antiretroviral therapy today: When to start treatment? How to start? When to switch? What to switch to? Whether to stop or not to stop treatment, and how? The method of a nominal group meeting was used and recommendations were graded for their strength and quality using a system based on the one adopted by the Infectious Diseases Society of America. Main conclusions are summarized and critically discussed in this consensus statement, as well as some of the most recent data supporting these recommendations are provided.

Abstract
The aim of the study was to evaluate the biochemical and virological response and the histological changes in 34 chronic hepatitis B anti-Hbe-positive patients treated with lamivudine at 100 mg/day orally for five years. Liver biopsies were performed in all patients at least 6 months before starting therapy and 3 months after the stop of treatment. After 12 months of therapy, 70.6% of patients showed evidence of HBV DNA clearance and normal ALT levels; 64.7% and 55.8% of patients maintained a complete response after two and three years of therapy, respectively, 47% after four years and 44.1% after five years. The histological activity index improved in 13%, remained unchanged in 61% and worsened in 26% of patients with tyrosine-methionine-aspartate-aspartate (YMDD) variants compared to 63, 27 and 0% without variants, respectively. The authors conclude that the clinical benefit of lamivudine is greatest for patients without YMDD variants after 5 years of extended treatment.

Abstract
OBJECTIVES To assess the prevalence of cryoglobulinemia in three groups of patients: HCV-positive/HIV-negative, HCV/HIV co-infected and HIV mono-infected. METHODS From September 2002 to December 2003, 58 patients with documented HCV infection, 70 subjects with HIV/HCV co-infection, and 48 subjects with HIV infection alone were enrolled. Serum samples were tested for detectable cryoglobulins, liver enzymes, HCV viral load and HCV genotypes. Plasma HIV-RNA levels and CD4+ cell count were also evaluated in HIV-positive subjects. RESULTS Cryoglobulinemia was detected in 24.1% HCV mono-infected, 14.2% HCV/HIV co-infected and 6% HIV mono-infected patients. A significant statistical correlation was found between the presence of cryoglobulins and HCV infection (P = 0.03), while cryoglobulins were unrelated to HIV mono-infection (P = 0.16) and HCV/HIV co-infection (P=0.7). No significant correlation was observed between the presence of cryoglobulinemia and alanine transaminase (ALT) levels, HCV viremia and duration of HCV infection. Circulating cryoglobulins in HIV patients were not correlated with plasma HIV viral load, CD4+ cell count or duration of HIV infection. Only two HCV mono-infected patients complained of arthralgia. CONCLUSION A similar rate of cryoglobulinemia prevalence was detected in the patient groups with an HCV-related infection. HIV infection does not appear to play a significant role in cryoglobulin production.

Abstract
Hepatitis C virus (HCV) variability is mainly attributed to the ability of the virus to respond to host immune pressure, acting as a driving force for the evolution of quasispecies. This study was aimed at studying the changes in HVR-1 heterogeneity and the evolution of HCV quasispecies in HIV/HCV-coinfected patients according to the pattern of response to highly active antiretroviral therapy (HAART). Sixteen HIV/HCV-coinfected patients harbouring HCV genotype 1 and who had been on HAART for at least 1 year, 8 showing increasing CD4+T-cell counts (immunological responders) and 8 showing a stable or decreasing CD4+ T-cell counts (immunological non-responders), were selected from a prospective cohort study. After 1 year of HAART, 11 patients showed HIV viral load <2.6 log10 cp/ml (virological responders), and 5 showed HIV viral load above this value (virological non-responders). Plasma samples, collected before starting therapy and after 1 year of HAART, underwent clonal sequence analysis for HVR-1 region of HCV. Non-synonymous/synonymous substitutions ratio (Ka/Ks), aminoacidic complexity (normalized Shannon entropy) and diversity (p-distance), were considered as parameters of quasispecies heterogeneity. After 1 year of HAART, heterogeneity of HVR-1 quasispecies significantly decreased in virological non-responders, whereas the heterogeneity tended to increase in virological responders. The differences in the evolution were less stringent, when considering immunological response. On the other hand, profound qualitative modifications of HVR-1 quasispecies were observed only in patients with both immunological and virological HAART response. On the whole, these findings suggest that, in patients undergoing HAART, the extent of HCV variability and the evolution of HVR-1 quasispecies is influenced by the pattern of response to antiretroviral therapy.

Abstract
The possibility of the non-parenteral Hepatitis C Virus (HCV) transmission is supported by the demonstration that the actual virus is present in several body fluids, including saliva. From a review of the literature many investigators have found the presence of HCV-RNA in saliva, however, widely contrasting results emerge, with detection rates ranging from 0-100%. To further examine HCV salivary shedding, saliva samples were collected from 46 chronically HCV-infected patients and tested for HCV-RNA and occult blood. Quantification and genotyping of serum HCV-RNA were also carried out for each patient. HCV-RNA was detected in 39.13% of the saliva samples. The viral salivary shedding was significantly related to viraemia levels, serum viral genotype and the presence of salivary occult blood. Our findings indicate that the HCV salivary shedding occurs in about one third of HCV infected patients, but seem to suggest that it is unlikely when the serum viral genotype is 3a. Moreover, blood leakage into the oral cavity is possibly the main source of the salivary HCV-RNA. Although the occurrence of the viral salivary shedding does not necessarily mean that HCV transmission occurs by saliva, our results suggest the need for further investigations into the biological factors possibly involved in HCV mucosal transmission related to both the source and the exposed subjects.

Abstract
Since 1996, AIDS has declined in the Italian population, but cases in foreign patients, including both recent immigrants and long-term residents, have increased from 3.9% in 1995-1996 to 15.4% in 2001-2002. This increase can only be partly explained by a higher migratory flow and might reflect a delayed access to health facilities and to antiretroviral therapy in migrants. We performed a survey for the year 2003 of HIV-infected immigrants to Italy from countries outside the European Union to verify which factors might influence a lack of access to highly active antiretroviral therapy (HAART). Italian centers of infectious diseases were requested to send sociodemographic and clinical data of HIV-infected immigrant patients. A total of 553 HIV-infected immigrants (49.9% women) were evaluated, representing 6.5% of all HIV-infected patients from these centers. The mean duration of residency in Italy was 6.6 +/- 5.0 years. The country of origin was Africa (64.5%), North and South America (24.2%), Eastern Europe (7.0%), and Asia (3.8%). A total of 407 of 553 patients (73.6%) were taking antiretroviral drugs at the time of screening. Females presented a younger age (p = 0.001), a lower frequency of Centers for Disease Control (CDC) stage B/C (p = 0.008) and a more frequent heterosexual exposure to HIV (p < 0.001), while no differences were observed for time of first positive serology (p = 0.7). CD4 cell count (p = 0.9) and log plasma HIV-RNA (p = 0.1). Characteristics of HAART patients were compared to those of nontreated patients, despite a CD4 cell count less than 350 cells/mm(3). No significant difference was found for gender, country of origin, risk factor, and years of Italian residence, while legal immigrants (p = 0.018) and registered in the National Health Service (p = 0.014) were significantly more likely to receive HAART compared to illegal immigrants.

Abstract
Our aim was to evaluate the prevalence of HIV infection in immigrants hospitalised in infectious disease settings in Italy during 2002. Each participating centre filled in a CRF which regarded the number of immigrants hospitalised in ordinary regime or in day-hospital during 2002 and, for HIV-positive patients only, some demographic (age, sex, origin) and clinical features (only HIV positivity or AIDS, new diagnosis or not, diagnosis of opportunistic infections). A total of 46 Infectious Diseases Units participated in the study and a total number of 2255 patients were tested for anti-HIV, irrespective of the cause of hospitalization, with 378 (16%) cases of positivity. Women accounted for 47.9%; the mean age of the population was 34.5 years. African patients showed a higher prevalence of HIV infections than subjects from other geographical areas (61.9% of all cases). Most HIV-infected patients were unaware of their positivity. In conclusion, HIV infection represents one of the main health problems among immigrants, particularly of African origin.

Abstract
The aim of this article is to retrospectively evaluate the patient characteristics and the most common infectious diseases in immigrant patients hospitalized in 46 Italian infectious disease clinics during 2002. The main Italian infectious disease clinics were invited to fill in a questionnaire that regarded the number and type of hospital admissions, the country of origin, and demographic features (age, sex, and resident state) of immigrants. A total of 46 clinics including 2255 patients participated in the study. Most patients were men (63%) with an age between 16 and 40 years (63.4%) covered by the National Health Service (71%) and coming from Africa (44.3%). The main infectious diseases observed were: 378 (16.76%) cases of HIV infection, 303 (13.43%) cases of tuberculosis diseases, 282 (12.5%) cases of various forms of viral hepatitis, 177 (7.84%) cases of respiratory diseases, and 196 (8.69%) gastrointestinal diseases. Tropical diseases found were 134 (5.94%) including 95 cases of malaria (70.9%). In conclusion, a broad range of diseases was noted in immigrants which were directly correlated with conditions of poverty. Only a few tropical diseases were diagnosed and therefore the immigrant should not be considered as an infectious disease carrier.

Abstract
Acute hepatitis C often progresses to chronic infection (70%). In this clinical study, we evaluated if early treatment with peginterferon alfa-2b can prevent acute hepatitis C from developing into a chronic disease. Six patients with acute hepatitis C, based on a well-documented hepatitis C virus (HCV) seroconversion with high alanine aminotransferase (ALT) levels (> 10 x ULN) and persistent HCV RNA titers after 3 months from disease onset, were consecutively treated with peginterferon alfa-2b at 1.5 microg/kg/weekly/sc for 24 weeks. The viral load was quantified by PCR assay. Response was defined as undetectable HCV RNA and normal ALT levels at the end of therapy and after a 6-month follow-up. All patients completed therapy; at the end of therapy, 5/6 patients (83%) responded and no relapses were observed during follow-up. No correlation was found between treatment response and pretreatment viral load, viral genotype, and interval between acute infection diagnosis and start of therapy.

Abstract
AIM To retrospectively evaluate the prevalence of hepatitis in immigrant patients hospitalised in 48 Italian Operative Unit of Infectious Diseases during 2002. METHODS AND PATIENTS in our study we included the clinical data of 2255 immigrated patients hospitalised, during the period between 01/01/2002-31/12/2002, in ordinary admission or in Day Hospital in Infectious Diseases O.U. and we have evaluated the prevalence of hepatitis in this population. RESULTS 282 patients affected by hepatitis has been evidenced (12.5% of total hospitalised patients). The prevalent form was HBV-related (41.6% in chronic forms and 48.4% in acute), while the rate for HCV were less (37.5% in chronic and 3% in acute). The most part of patient were men (59.6%), with a mean age of 34.2 years and come from east-European countries (34.39%). CONCLUSION Viral hepatitis are the third infectious diseases evidenced in immigrated population. HBV-chronic hepatitis is the prevalent form in immigrated patients, as expression of absence of vaccine prophylaxis in many countries. HCV-form was less frequent and it is particularly presents in east-European patients, probably as expression of endogenous drug abuse.

Abstract
The prognostic role of GB virus type C (GBV-C) viraemia in HIV-infected subjects treated with highly active antiretroviral therapy (HAART) is still undefined, The aim of this analysis is to assess the relationship between GBV-C infection and response to antiretroviral therapy among HIV-infected subjects initiating HAART when antiretroviral-naive. A prospective, observational study of 400 HIV-infected patients with measurements of GBV-C RNA, hepatitis C virus (HCV) antibodies and HCV RNA determined from plasma stored prior to HAART initiation, Time to virological (achieving HIV RNA ≤500 copies/ml) and immunological success (a CD4+ count increase of ≥200cells/μl), and the time to virological relapse (confirmed HIV RNA >500 copies/ml) were assessed by Kaplan-Meier methods and Cox proportional hazard regression model. Of the subjects, 117 (29.3%) were GBV-C positive and, overall, 351 (87.8%) patients achieved virological success, After controlling for a number of confounders including HCV RNA, GBV-C viraemic patients experienced a significantly lower risk of HIV rebound than those who were GBV-C negative [relative hazard (RH)=0.56, 95% CI: 0.34–0.93, P=0.03], Conversely, the probability of achieving initial virological success or CD4+ count response after HAART did not differ between GBV-C-negative and -positive subjects, These results suggest that GBV-C coinfection may play a role in determining the rate of HIV rebound possibly by competing with HIV replication after HIV load has been successfully suppressed by HAART.

Abstract
High level HIV-1 drug resistance in recently infected treatment-naive individuals correlates with sub-optimal virological responses to highly active antiretroviral therapy (HAART). To determine whether genotypic HIV-1 drug resistance in chronic naive patients, as interpreted by various systems, could predict the virological outcomes of HAART, isolates from patients enrolled in a prospective observational cohort (ICoNA) prior to treatment start were genotyped. Genotypic susceptibility scores (GSS) assigned to the initial HAART regimens using the interpretations of pre-therapy resistance mutations by 13 systems were related to virological outcomes. Of 415 patients, 42 (10%) had at least one major resistance mutation. According to the different interpretations, 1.9–20.5% of patients had some level of resistance to at least one drug in the initial regimen. In multivariable analysis, GSS from two systems significantly predicted the time to virological success: Rega 5.5, for each unit increase in GSS adjusted relative hazard (RH) 1.86 [95% confidence intervals (95% CI): 1.15–3.02] and hivresistanceWeb v3, RH 1.87 (95% CI: 1.00–3.48). With three other systems, GSS showed a trend towards a significant prediction of success: Retrogram 1.6, RH 2.33 (95% CI: 0.98–5.53), Menéndez 2002, RH 2.36 (95% CI: 0.97–5.72) and Stanford hivdb, RH 2.06 (95% CI: 0.94–4.49). Genotypic resistance testing coupled with adequate interpretation in chronic naive patients can usefully identify those at risk of sub-optimal virological response to HAART.

Abstract
Intrabiliary rupture of a hydatid liver cyst is a rare occurrence which may result in the development of obstructive jaundice and cholangitis. In this report we discuss the diagnostic and therapeutic management of a patient in whom the parasitic nature of cholangitis was underestimated due to the small size and site of the cyst, and to the misleading concomitant presence of cholelithiasis.

Abstract
We examined the impact of a lamivudine-containing highly active antiretroviral therapy (HAART) regimen on 164 hepatitis B virus/HIV co-infected individuals starting their first HAART. Lamivudine-treated patients (accounting for 73% of the study population) showed a significantly lower level of alanine aminotransferase over follow-up [–81.1 mU/ml mean difference; 95% confidence intervals (95% CI): –30.3; –131.7, P=0.003] and a significantly reduced risk of liver-related morbidity/mortality [Relative hazard (RH)=0.07; 95% CI: 0.01–0.38, P=0.002] than those starting a lamivudine sparing-regimen.

Abstract
OBJECTIVES To evaluate the level of 90K as a predictor of AIDS; to describe 90K levels over time after HIV serconversion; and to evaluate the 90K level as a marker of the maturity of infection. DESIGN Prospective incident cohort of HIV-infected individuals with documented dates of seroconversion. METHODS Cox models were applied to estimate the crude and adjusted relative hazards (RH) of AIDS by level of 90K. Regression models were applied to describe the temporal trend and the correlates of the level of 90K over time after HIV-seroconversion. Logistic models were applied to evaluate the probability of a sample of 90K having been taken within a certain time period after HIV-seroconversion. RESULTS The study population consisted of 150 participants of the Italian Seroconversion Study. A total of 429 measurements of 90K were taken. Both early and later measurements of 90K were highly predictive of AIDS, also when adjusting for CD4 lymphocyte count and HIV load. The 90K level (U/ml) increased by 10% annually (95% CI: 7%-13%); the increase over time was linear. IDUs had higher 90K levels than heterosexuals and homosexuals over the course of HIV disease. High 90K levels were highly predictive of distant seroconversions (age-adjusted probability, 74%), whereas were poorly predictive of recent seroconversions (age-adjusted probability, 5%); the results were similar for the predictability of CD4 lymphocyte count. CONCLUSIONS The level of 90K is a useful prognostic tool for clinical purposes. As a marker of the maturity of infection, 90K is similar to the CD4 lymphocyte count, with the advantage of being able to use serum instead of fresh whole blood. It has a good capacity to identify distant infections.

Abstract
The aim was to confirm the influence of HLA Class II antigens on the progression of HCV infection and to assess the relationship between these antigens and histological damage, HCV viral load and HCV genotype. 143 patients were enrolled and divided into three groups. Group A included 34 anti-HCV positive, HCV-RNA negative patients with ALT persistently normal; group B included 39 patients with HCV-RNA positive and abnormal ALT level; group C included 70 normal subjects. Serological HCL typing was performed with lymphocytotoxicity test by Terasaky and McClelland, using lymphobeads HLC class II. The frequency of HLA DR11 (5) was significantly higher in the control group (52.9%) and in group A (64.7%), than in group B (28.2%). Allele HLA DR6 was demonstrated in a similar proportion (26%) among control group and group B, while HLA DR14 (6) was less frequent among controls (18% vs 1.4%). In group A the frequency of HLA DR14 (6) was 3% compared to group B, HLA DR17 (3) was prevalent (15.4%) in group B. Liver damage was associated with the detection of HLA DR14 (6) and HLD DR17 (3) antigens. Significantly lower levels of HCV-RNA were measured in subjects with HLA DR11 (5) than in these with either DR6 or DR17 (3). HLA class II antigens appear crucial for resolution or progression of HCV hepatitis. The punctual identification of these genetic factors may, therefore, prove to be useful in predicting disease evolution, in guiding the appropriate therapy for patients with poor prognosis, and in encouraging the development of now therapeutic strategies.
