Abstract
The molecular epidemiology of HIV-1 in Italy is becoming increasingly complex, mainly due to the spread of non-B subtypes and the emergence of new recombinant forms. We previously characterized the outbreak of the first Italian circulating recombinant form (CRF60_BC), occurring among young MSM living in Apulia between the years 2009 and 2011. Here we show a 5-year follow-up surveillance to trace the evolution of CRF60_BC and to investigate its further spread in Italy. We collected additional sequences and clinical data from patients harboring CRF60_BC, enrolled at the Infectious Diseases Clinic of the University of Bari. In addition to the 24 previously identified sequences, we retrieved 27 CRF60_BC sequences from patients residing in Apulia, whose epidemiological and clinical features did not differ from those of the initial outbreak, i.e., the Italian origin, young age at HIV diagnosis (median: 24 years; range: 18–37), MSM risk factor (23/25, 92%) and recent infection (from 2008 to 2017). Sequence analysis revealed a growing overall nucleotide diversity, with few nucleotide changes that were fixed over time. Twenty-seven additional sequences were detected across Italy, spanning multiple distant regions. Using a BLAST search, we also identified a CRF60_BC sequence isolated in United Kingdom in 2013. Three patients harbored a unique second generation recombinant form in which CRF60_BC was one of the parental strains. Our data show that CRF60_BC gained epidemic importance, spreading among young MSM in multiple Italian regions and increasing its population size in few years, as the number of sequences identified so far has triplicated since our first report. The observed further divergence of CRF60_BC is likely due to evolutionary bottlenecks and host adaptation during transmission chains. Of note, we detected three second-generation recombinants, further supporting a widespread circulation of CRF60_BC and the increasing complexity of the HIV-1 epidemic in Italy.

Abstract
OBJECTIVE Our cross-sectional study aimed at evaluating the diagnostic performance of Focused Assessment with Sonography for HIV-associated tuberculosis (FASH) to detect extrapulmonary tuberculosis in extremely resource-limited settings, with visceral leishmaniasis as a differential diagnosis with overlapping sonographic feature. DESIGN Cross-sectional study. SETTING Voluntary Counselling and Testing Centre (VCT) of Yirol Hospital, South Sudan. PARTICIPANTS From May to November 2017, 252 HIV-positive patients out of 624 newly admitted to VCT Centre were registered for antiretroviral treatment. According to the number of trained doctors available to practise ultrasound (US) scan, a sample of 100 patients were screened using the FASH protocol. INTERVENTIONS Following a full clinical examination, each patient was scanned with a portable US scanner in six different positions for pleural, pericardial, ascitic effusion, abdominal lymphadenopathy and hepatic/splenic microabscesses, according to the FASH protocol. A k39 antigen test for visceral leishmaniasis was also performed on patients with lymphadenopathy and/or splenomegaly. All demographic, clinical and HIV data, as well as FASH results and therapy adjustments, were recorded following the examination. RESULTS The FASH protocol allowed the detection of pathological US findings suggestive of tuberculosis in 27 out of the 100 patients tested. Overall, FASH results supported tuberculosis treatment indication for 16 of 21 patients, with the treatment being based exclusively on FASH findings in half of them (8 patients). The group of FASH-positive patients had a significantly higher proportion of patients with CD4 count below 0.2 x109/L (n=22, 81%) as compared with FASH-negative patients (n=35, 48%) (p=0.003). Moreover, 48% (n=13) of FASH-positive patients had CD4 below 100 cells/mm3. All patients tested had a negative result on k39 antigen test. CONCLUSION FASH was found to be a relevant diagnostic tool to detect signs of tuberculosis. Further research is needed to better define a patient profile suitable for investigation and also considering diagnostic accuracy.

Infection 2019; 47:441-446. [PMID: 30649685 DOI: 10.1007/s15010-019-01268-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2018] [Accepted: 01/06/2019] [Indexed: 01/17/2023]
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
Liver fibrosis is accelerated in human immunodeficiency virus/hepatitis C virus (HIV/HCV) coinfected compared with HCV monoinfected patients, due to multiple cofactors. Recently, HLA-B18 haplotype has been associated with short-term liver disease progression in this population. Our aim was to assess the influence of HLA-B18 on the fibrosis process in HIV/HCV coinfected individuals, untreated for HCV, during a long-term follow-up. All consecutive HIV/HCV co-infectedcoinfected patients followed in our center, with positive HCV-RNA and available human leukocyte antigen (HLA) haplotypes (determined by sequence-specific oligonucleotide primed polymerase chain reaction and simple sequence repeats polymerase chain reaction using Luminex Technology) were included. Liver fibrosis progression was assessed by means of fibrosis-4 index for liver fibrosis (FIB-4) and AST to platelet ratio index. The association between FIB-4 score over time and laboratory and clinical parameters, including HLA, was evaluated by univariate and multivariate multilevel generalized linear models. A total of 29 out of 148 screened patients were excluded because of spontaneous HCV clearance (27% were HLA-B18+). Among the remaining 119 individuals (82% males; median age at first visit = 30 years [interquartile range, IQR, 26-35]; median follow-up = 21.5 years [IQR, 15-25]), 26% were HLA-B18+. No baseline differences were evidenced between HLA-B18+ and B18- patients. Fibrosis progression was significantly faster in HLA-B18+ than in HLA-B18- patients ( P < 0.001) (Figure 1). At univariate analysis, age ( P < 0.001), HLA-B18 haplotype ( P = 0.02) and HIV-RNA viral load overtime ( P < 0.001) were associated with liver disease progression. At multivariate analysis, only age ( P < 0.001) remained independently associated with liver fibrosis progression. Our data suggest a possible association between HLA-B18 and an accelerated liver fibrosis in HIV/HCV coinfected with a long-term follow-up.

Abstract
BACKGROUND AND OBJECTIVES We aimed to investigate to what extent a first-line DTG-based ART regimen reduces HIV-RNA in semen compared to plasma. STUDY DESIGN In this prospective, observational study, ART-naïve, HIV-infected males starting their first ART regimen with DTG plus TDF/FTC or ABC/3TC were enrolled. Paired blood (BP) and seminal plasma (SP) samples were collected at baseline (T0) and at week-2/4/12/24 after ART initiation. Sexually transmitted infections (STI) were ruled out before enrolment. RESULTS Median baseline HIV-RNA levels were lower in SP compared to BP (657 versus 38.200 copies/ml, p < 0.001), three subjects had undetectable semen HIV-RNA. After 12 weeks of treatment, HIV-RNA was below the quantification limit in both BP and SP of 11 pts (61.1%). Discordant results were obtained in 6 subjects (33.3%), showing quantifiable HIV-RNA in blood only (2 cases) and in semen only (4 cases). Finally, one subject had a positive HIV-RNA in SP/BP. At W24, only in 2/16 subjects (12.5%) HIV-RNA was detectable in semen, while in the others it was negative on SP/BP. No concurrent STI was found in subjects with detectable VL in semen. CONCLUSIONS DTG demonstrated effectiveness in reducing VL with different kinetics in blood and semen, despite seminal viral suppression after 6 months of ART was not obtained in the totality of subjects.

Abstract
Co-infection between malaria and HIV has major public health implications. The aims of this study were to assess the malaria prevalence and to identify predictors of positivity to malaria Test in HIV positive patients admitted to the health center São Lucas of Beira, Mozambique. A retrospective cross-sectional study was performed from January 2016 to December 2016. Overall, 701 adult HIV patients were enrolled, positivity to malaria test was found in 232 (33.0%). These patients were found to be more frequently unemployed (76.3%), aged under 40 (72.0%), with a HIV positive partner (22.4%) and with a CD4 cell count <200 (59.9%). The following variables were predictors of malaria: age under 40 (O.R. = 1.56; 95%CI: 1.22–2.08), being unemployed (O.R. = 1.74; 95%CI: 1.24–2.21), irregularity of cotrimoxazole prophylaxis’s (O.R. = 1.42; 95%CI: 1.10–1.78), CD4 cell count <200 (O.R. = 2.01; 95%CI: 1.42–2.32) and tuberculosis comorbidity (O.R. = 1.58; 95%CI: 1.17–2.79). In conclusion, high malaria prevalence was found in HIV patients accessing the out-patients centre of São Lucas of Beira. Our findings allowed us to identify the profile of HIV patients needing more medical attention: young adults, unemployed, with a low CD4 cell count and irregularly accessing to ART and cotrimoxazole prophylaxis.

Abstract
The purpose of this article is to provide insights into the demand for pregnancy-related health services by adolescent girls and young women in Mozambique. We analysed the patient registers for the first year of operation (2014) of the Servicios Amigos dos Adolescentes (SAAJ) [Friendly Services for Adolescents] clinics in Beira, Mozambique. These registers provide details of the service demands of, and services provided to the 8 290 adolescent girls and young women who accessed the 6 SAAJ clinics in 2014. Analysis of that record, with disaggregation of the patients according to age (9 years or less; 10-14; 15-19; 20-24; 25 and older), show that 3 021 (36%) were pregnant or had previously been pregnant; most being girls in the 15-19 age band (59%). Being pregnant or having been pregnant previously was associated with dropping out of school. Of all the girls and women, 60% agreed to HIV testing and counselling; the HIV prevalence rate amongst this group was 4-5% amongst adolescents and 25% amongst women 25 years and older. A minority of the girls and women who were pregnant or had been pregnant previously agreed to HIV testing and counselling. Notwithstanding the limitations for analysis, the results were alarming: substantially high HIV prevalence rates were indicated (2% amongst 10-14 year old girls; 8% amongst 15-19 year olds; 10% amongst 20-24 year olds; and 28% amongst >24 year olds). The data from the SAAJ clinics and results pertain only to conditions in Beira. However, as the first empirical assessment of pregnancy-related service demand amongst adolescent girls and young women in the country and involving a relatively large sample, we contend that this study affirms the need for expansion of sexual and reproductive health (SRH) services, including HIV services, for adolescent girls and young women in Mozambique.

Abstract
BACKGROUND Recent studies suggest that transmitted drug resistance (TDR) may be decreasing in latest years, likely because of the reduced frequency of acquired resistance. However, specific risk factors, geographical areas and special HIV-infected populations may be disproportionally affected by TDR. OBJECTIVES Correlates of TDR and time trends were evaluated from 2007 to 2014. STUDY DESIGN We evaluated the genotypic results of 2155 naïve patients enrolled in the I.Co.N.A cohort at 23 clinical Centers in Italy between 2007 and 2014. A weighted analysis was performed to account for the patients enrolled in the cohort in each clinical Centre at each biennium (total number of patients: 3737). RESULTS Overall prevalence of TDR was 10.7%. Independent predictors of TDR were sexual risk factor (OR 2.315, p = 0.020) and non-Italian geographical origin (OR 1.57, p = 0.038). The weighted prevalence of TDR was 10.5% with a stable proportion over calendar years. Generally, TDR prevalence was numerically higher, although not significantly, in clinical Centers of metropolitan areas with more than 3 millions of residents as compared to others (11.3% vs. 9.2%). The difference in TDR prevalence between these Centers decreased in more recent years. CONCLUSIONS A stable frequency of TDR was observed during the most recent years in Italy, with opposite and converging trends in large metropolitan areas as compared to the rest of the country, suggesting a more homogeneous spread of TDR across the country in latest years. Concerns remain for sexual route of infection and non-Italian origin, reinforcing the need for specific prevention strategies prioritizing specific populations.

Abstract
The concept of “children at risk” changes worldwide according to each specific context. Africa has a large burden of overall risk factors related to childhood health and development, most of which are of an infective or social origin. The aim of this study was to report and analyze the volumes of activities of fifteen At Risk Child Clinics (ARCCs) within the Beira District (Mozambique) over a 3 year-period in order to define the health profile of children accessing such health services. We retrospectively analyzed the data from all of the children accessing one of the 15 Beira ARCCs from January 2015 to December 2017. From this, 17,657 first consultations were registered. The motivations for accessing the services were in order of relevance: HIV exposure (n. 12,300; 69.7%), other risk conditions (n. 2542; 14.4%), Moderate Acute Malnutrition (MAM) (n. 1664; 9.4%), Severe Acute Malnutrition (SAM) (n. 772; 4.4%), and TB exposure (n. 542; 3.1%). During the first consultations, 16,865 children were screened for HIV (95.5%), and 7.89% tested HIV-positive. In our three years of experience, HIV exposure was the main indication for children to access the ARCCs in Mozambique. ARCCs could represent a strategic point to better understand health demands and to monitor the quality of care provided to this vulnerable population group, however significant effort is needed to improve the quality of the data collection.

Abstract
OBJECTIVES The aim was to evaluate the evolution of transmitted HIV-1 drug resistance (TDR) prevalence in antiretroviral therapy (ART)-naïve patients from 2006 to 2016. METHODS HIV-1 sequences were retrieved from the Antiviral Response Cohort Analysis (ARCA) database and TDR was defined as detection of at least one mutation from the World Health Organization (WHO) surveillance list. RESULTS We included protease/reverse transcriptase sequences from 3573 patients; 455 had also integrase sequences. Overall, 68.1% of the patients were Italian, the median CD4 count was 348 cells/μL [interquartile range (IQR) 169-521 cells/μL], and the median viral load was 4.7 log10 HIV-1 RNA copies/mL (IQR 4.1-5.3 log10 copies/mL). TDR was detected in 10.3% of patients: 6% carried mutations to nucleos(t)ide reverse transcriptase inhibitors (NRTIs), 4.4% to nonnucleos(t)ide reverse transcriptase inhibitors (NNRTIs), 2.3% to protease inhibitors (PIs), 0.2% to integrase strand transfer inhibitors (INSTIs) and 2.1% to at least two drug classes. TDR declined from 14.5% in 2006 to 7.3% in 2016 (P = 0.003): TDR to NRTIs from 9.9 to 2.9% (P = 0.003) and TDR to NNRTIs from 5.1 to 3.7% (P = 0.028); PI TDR remained stable. The proportion carrying subtype B virus declined from 76.5 to 50% (P < 0.001). The prevalence of TDR was higher in subtype B vs. non-B (12.6 vs. 4.9%, respectively; P < 0.001) and declined significantly in subtype B (from 17.1 to 8.8%; P = 0.04) but not in non-B subtypes (from 6.1 to 5.8%; P = 0.44). Adjusting for country of origin, predictors of TDR were subtype B [adjusted odds ratio (AOR) for subtype B vs. non-B 2.91; 95% confidence interval (CI) 1.93-4.39; P < 0.001], lower viral load (per log10 higher: AOR 0.86; 95% CI 0.75-0.99; P = 0.03), site in northern Italy (AOR for southern Italy/island vs. northern Italy, 0.61; 95% CI 0.40-0.91; P = 0.01), and earlier calendar year (per 1 year more recent: AOR 0.95; 95% CI 0.91-0.99; P = 0.02). CONCLUSIONS The prevalence of HIV-1 TDR has declined during the last 10 years in Italy.

Abstract
BACKGROUND Dolutegravir (DTG) is a next-generation HIV integrase inhibitor (INI) with an increased genetic barrier to resistance with respect to raltegravir (RAL) or elvitegravir (EVG). Few data are available on the durability of DTG-containing regimens. OBJECTIVES We aimed at investigating the duration of the DTG-containing regimen, the occurrence of an HIV-1 RNA blip, and factors associated with DTG virological response. STUDY DESIGN From the Antiviral Response Cohort Analysis database, we selected 89 HIV-1-positive four-class-experienced subjects who started DTG after receiving RAL or EVG. Factors associated with durability and virological response were analysed by logistic regression. RESULTS After a median duration of 18.8 [0.4-76.2] months, 79/89 (88.8%) subjects were still on DTG. All subjects remaining on DTG at the end of follow-up had undetectable HIV-1 RNA, compared to 5/10 subjects who discontinued DTG. DTG discontinuation was less frequent in patients who had experienced ≥10 regimens (HR 0.11, p = 0.040). The probability of having an HIV-1 RNA positive value at the last follow-up significantly increased in patients with non-B HIV-1 subtype (HR 5.77, p < .001) and significantly decreased in patients with CD4 nadir >200/μL (HR 0.29, p = 0.038), with more than 10 previous regimens (HR 0.27, p = 0.040), and who harbored virus with IN mutations (HR 0.12, p = 0.023) at DTG start. CONCLUSIONS After previous exposure to first-generation INIs, treatment with DTG showed long durability and did not show virological rebound after virological suppression. Subjects infected with a non-B HIV-1 subtype had a greater risk of having detectable HIV-1 RNA at the last observation.

Pathways of care for HIV infected children in Beira, Mozambique: pre-post intervention study to assess impact of task shifting. BMC Public Health 2018; 18:703. [PMID: 29879951 PMCID: PMC5992883 DOI: 10.1186/s12889-018-5646-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Accepted: 05/31/2018] [Indexed: 11/25/2022] Open
Abstract
Background In 2013, Mozambique implemented task-shifting (TS) from clinical officers to maternal and child nurses to improve care for HIV positive children < 5 years old. A retrospective, pre-post intervention study was designed to evaluate effectiveness of a new pathway of care in a sample of Beira District Local Health Facilities (LHFs), the primary, local, community healthcare services. Methods The study was conducted by accessing registries of At Risk Children Clinics (ARCCs) and HIV Health Services. Two time periods, pre- and post-intervention, were compared using a set of endpoints. Variables distribution was explored using descriptive statistics. T-student, Mann Whitney and Chi-square tests were used for comparisons. Results Overall, 588 HIV infected children (F = 51.4%) were recruited, 330 belonging to the post intervention period. The mean time from referral to ARCC until initiation of ART decreased from 2.3 (± 4.4) to 1.1 (± 5.0) months after the intervention implementation (p-value: 0.000). A significant increase of Isoniazid prophylaxis (O.R.: 2.69; 95%CI: 1.7–4.15) and a decrease of both regular nutritional assessment (O.R. = 0.45; 95%CI: 0.31–0.64) and CD4 count at the beginning of ART (O.R. = 0.46; 95%CI: 0.32–0.65) were documented after the intervention. Conclusions Despite several limitations and controversial results on nutrition assessment and CD4 count at the initiation of ART reported after the intervention, it could be assumed that TS alone may play a role in the improvement of the global effectiveness of care for HIV infected children only if integrated into a wider range of public health measures.

Abstract
Objective Tuberculosis (TB) remains a major global health issue, ranking in the top ten causes of death worldwide. A deep understanding of factors influencing poor treatment outcomes may allow the development of additional treatment strategies, focused on the most vulnerable groups. Aims of the study were: (i) to evaluate the treatment outcome among TB subjects followed in an outpatient setting and (ii) to analyze factors associated with treatment failure in newly diagnosed patients with pulmonary TB in Beira, the second largest city of Mozambique. Results A total of 301 TB adult patients (32.6% females) were enrolled. Among them, 62 (20.6%) experienced a treatment failure over a 6 months follow-up. On multivariate model, being males (O.R. = 1.73; 95% CI 1.28–2.15), absence of education (O.R. = 1.85; 95% CI 1.02–2.95), monthly income under 50 dollars (O.R. = 1.74; 95% CI 1.24–2.21) and being employed (O.R. = 1.57; 95% CI 1.21–1.70), low body mass index values (O.R. = 1.42; 95% CI 1.18–1.72) and HIV status (O.R. = 1.42; 95% CI 1.10–1.78) increased the likelihood of therapy failure over 6 months of follow-up. In this study, patients who need more medical attention were young males, malnourished, with low income and low educational degree and HIV positive. These subjects were more likely to fail therapy.

Abstract
Background In vitro, gp120 of both X4 and R5 HIV-1 strains activates human hepatic stellate cells, but if it can promote liver fibrosis in vivo is unknown. We aimed to evaluate if patients carrying X4 or R5 strains have a different liver fibrosis (LF) progression over time. Methods A total of 1,137 HIV-infected patients in ICONA cohort (21% females, 7% HCV co-infected) with an available determination of HIV-1 co-receptor tropism (CRT), a Fibrosis-4 Index for Liver Fibrosis (FIB-4) <3.25 and at least one-year follow-up were included. CRT was assessed by gp120 sequencing on plasma RNA and geno2pheno algorithm (10% false positive rate) or by Trofile. LF was assessed by means of FIB-4. LF progression was defined as an absolute score increase or a transition to higher fibrosis stratum and/or occurrence of liver-related clinical events. Results A total of 249 (22%) patients carried X4 strains, which were associated with older age, lower CD4 count, lower nadir CD4, and intravenous drug use. Overall, X4 and R5 patients had similar baseline FIB-4 scores and similar mean FIB-4 slope after a median follow-up of 35 months. There was no difference between X4 and R5 for time to LF progression (p = 0.925). Estimated risk of LF at 24 months (95% CI) after baseline in X4 and R5 was 10.6% (8.3–12.9) and 9.9% (5.9–14.0), respectively. Age, HCV co-infection, diabetes, HIV-duration, HIV-RNA>100.000 cp/mL, antiretroviral therapy exposure were associated with LF progression at multivariate analysis. Conclusions A slight LF progression over time was observed in HIV-infected patients. No difference was demonstrated for X4 and R5 HIV-1 strains in accelerating LF evolution.

Abstract
Introduction Data regarding the association between diabetes mellitus (DM) and tuberculosis (TB) in Africa are scarce. DM screening among TB patients in Mozambique was carried out. Methods The study was implemented from January to August 2016 in three Urban Health Centers in Beira, Mozambique and recruited adult (>18 years) patients newly diagnosed with pulmonary TB. Results Three hundred and one patients were enrolled (67.4%, males mean age 31.7(SD 11 years). Diabetes was diagnosed in only 3 patients (1%) and impaired glucose tolerance (IGT) in an additional 6 subjects (2%). Conclusion A lower than expected prevalence of DM was observed, which could be explained by the lack of traditional risk factors for DM (overweight, age over 45 years, hypertension and smoking) in Mozambique.

Abstract
BACKGROUND Direct antiviral agents (DAAs) for chronic hepatitis C showed great effectiveness and good safety profile. So far, few data are available about their use in elderly subjects. AIM To assess management, safety and outcome of DAAs treatments in the elderly. METHODS This retrospective, single-centre study enrolled all patients aged ≥65 years, compared by age (group A: 65-74 years, group B: ≥75 years), who completed DAAs between February 2015-November 2016. Variables potentially associated to adverse events (AEs) were analyzed. Sustained virological response (SVR) was evaluated at 12-weeks follow-up. RESULTS DAAs were administered to 221 patients aged ≥65 years (males: 112; group A: 130, group B: 91). Prescribed regimens were: sofosbuvir-based: 44 patients (19.9%), simeprevir-based: 25 (15%), ledipasvir-based: 49 (22.2%), daclatasvir-based: 12 (5.4%), paritaprevir/ritonavir+ombitasvir±dasabuvir: 91 (41.2%). Ribavirin was used in 121 patients. In 58 subjects co-medications were adjusted due to drug interactions. At least one AE occurred in 130 patients, including 13 SAEs, mainly in older subjects (p=0.04). Female sex (p=0.04), liver stiffness (p=0.023), use of simeprevir (p=0.03) and ribavirin (p=0.009) were associated with AEs. SVR-12 was achieved in 96,9% of subjects. CONCLUSIONS A careful baseline evaluation and a strict monitoring allow to optimise management and outcome of DAAs in elderly.

Abstract
BACKGROUND Direct-acting antiviral (DAA)-based treatment of hepatitis C virus (HCV) has been associated with high sustained virological response (SVR) rates and good tolerability in randomized clinical trials. This study was performed to assess the safety and effectiveness of DAAs in both HCV mono-infected and HIV/HCV co-infected patients. METHODS All consecutive HCV-infected patients, including HIV/HCV co-infected patients, receiving DAA-based treatment from February 2015 to September 2016 at the study clinic were included. Clinical, virological, and biochemical data were retrieved. The primary end-point was the SVR12 (HCV RNA undetectable 12 weeks after the end of treatment) is commonly used worldwide. The secondary end-point was the safety profile of DAAs during the treatment period. RESULTS A total of 382 patients were included; 62 were HIV/HCV co-infected. Cirrhosis was found in 256 patients (67.4%). SVR12 was achieved in 365/382 (95.5%) individuals (58/62 HIV/HCV co-infected, 93.5%) in the intention-to-treat (ITT) analysis. A platelet count <90×109/l (odds ratio (OR) 4.12, 95% confidence interval (CI) 1.5-11.3, p=0.006), HCV genotype 3 infection (OR 5.49, 95% CI 1.9-15.7, p=0.002), liver stiffness >20kPa (OR 3.05, 95% CI 1.03-8.96, p=0.04), and Model for End-Stage Liver Disease (MELD) score >10 (OR 5.27, 95% CI 1.16-23.8, p=0.03) were associated with lower SVR rates. On multivariate analysis, only genotype 3 infection remained a negative predictor of SVR (OR 21.6, 95% CI 3.81-123, p=0.001). Treatment discontinuation was observed in 10 subjects. Severe adverse events (SAEs) occurred in 17 patients (4.5%). CONCLUSIONS High SVR12 rates were observed in both HCV mono-infected and HIV/HCV co-infected individuals. Overall, DAA-based treatment was safe and there were no differences in terms of SAEs and treatment discontinuation between the two groups.

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
Background Imported cases of multidrug resistant Plasmodium falciparum and treatment failure with artemisinin-based regimens, although rare, have been described also in Western countries and their management is often challenging. This is also due to an inadequate knowledge and implementation of health prevention measures. Case report A complex case of imported malaria caused by Plasmodium vivax/P. falciparum isolates in a patient who was not taking chemoprophylaxis while he was travelling in Cambodia is reported in this article. After failures of artemisinin-based and both oral and intravenous quinine-based regimens, a multidrug resistant P. falciparum was detected. The patient was successfully treated with atovaquone–proguanil. Conclusions This experience highlights the importance of a careful management that should be based not only on the most up-to-date guidelines, but also on the awareness of a rapidly evolving scenario.

Abstract
The effectiveness of modern antiretroviral therapies (ART) transformed HIV infection into a chronic disease characterized by a persistent condition of inflammation and immune activation. For this reason, even thought AIDS-related mortality has been reduced with an increased life expectancy, patients living with HIV infection are more likely to develop non-AIDS events despite the achievement of a complete suppression of HIV replication. Hence, the scientific community feels the need to find new biomarkers which would be suitable in clinical practice for identifying patients who require a close monitoring because of an increased risk of developing comorbidities. A renewed interest has emerged about the usefulness of CD4/CD8 ratio as a strong marker of immune activation and immune senescence. Recently, many studies have underlined that CD4/CD8 ratio might represent a good predictor of AIDS and non-AIDS events. Herein, the potential role of the CD4/CD8 ratio for the monitoring of HIV patients in different clinical settings is reviewed.

Abstract
Dynamics of human immunodeficiency virus type 1 (HIV-1) tropism after antiretroviral therapy (ART) initiation and their association with disease progression are poorly investigated.This was a cohort study on subjects from the ICONA cohort receiving ART with persistently detectable (PD) or persistently undetectable (PU) viral load (VL) and with stored plasma or peripheral blood mononuclear cell (PBMC) samples at 2 time-points (T1, T2) after ART initiation. HIV-1 co-receptor tropism was determined by V3-loop sequencing and the geno2pheno algorithm. A switch in viral tropism was defined if the tropism classification at T2 differed from that observed at T1. Time to disease progression, defined as the occurrence of a new acquired immune deficiency syndrome (AIDS)-defining event/death from T2, was also evaluated.One hundred ninety-five patients were analyzed (124 PD, 71 PU). Over a median follow-up of 22.6 (19.8-28.1) months, PD and PU patients showed similar rates (95% confidence interval) of switch to a non-R5 virus [PD: 6.9 (3.7-11.2)/100-person-years of follow-up (PYFU); PU: 8.0 (3.4-14.5)/100-PYFU; P = 0.63] and of switch to a R5 virus [PD: 15.4 (7.3-26.4)/100-PYFU; PU: 8.1 (2.5-16.7)/100-PYFU; P = 0.38]. Switch to non-R5 virus was predicted by nadir CD4+ before T1.Twenty-two (18%) PD and 4 (6%) PU subjects experienced disease progression (P = 0.02). The risk of disease progression was independently associated with a switch in co-receptor tropism (adjusted hazard ratio = 4.06, 95% CI: 1.20-13.80, P = 0.03) as well as age, AIDS diagnosis, nadir CD4+ before T2, current CD4+, and VL.Switch of HIV-1 tropism under ART occurs in both directions, with similar rates in subjects with PD or PU VL and it might be predictive of future unfavorable clinical outcome.

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.
