Abstract

HIV-1 drug resistance represents a major obstacle to infection and disease control. This retrospective study analyzes trends and determinants of resistance in antiretroviral treatment (ART)-exposed individuals across 7 countries in Europe. Of 20 323 cases, 80% carried at least one resistance mutation: these declined from 81% in 1997 to 71% in 2008. Predicted extensive 3-class resistance was rare (3.2% considering the cumulative genotype) and peaked at 4.5% in 2005, decreasing thereafter. The proportion of cases exhausting available drug options dropped from 32% in 2000 to 1% in 2008. Reduced risk of resistance over calendar years was confirmed by multivariable analysis. © 2013 The Author.

Abstract

Introduction: This study aimed at defining protease (PR) resistance mutations associated with darunavir (DRV) failure and PR resistance evolution at DRV failure in a large database of treatment-experienced human immunodeficiency virus (HIV) patients. Results: Overall, 1,104 patients were included: 118 (10.7%) failed at a median observation time of 16 months. The mean number of PR mutations at baseline was 2.7, but it was higher in patients who subsequently failed DRV. In addition, the number of PR mutations increased at failure. The increase in the mean number of mutations was completely related to mutations considered to be associated with DRV resistance following the indications of the main DRV clinical trials. Discussion The higher statistical difference at baseline between failing versus non-failing patients was observed for the V32I and I84V mutations. At DRV failure, the major increase was still observed for V32I; I54L, V11I, T74P and I50V also increased. Despite the increment in the mean number of mutations per patient between baseline and failure, in 21 patients (17.8%) at baseline and 36 (30.5%) at failure, no PR mutation was detected. Conclusion: The HIV-DB interpretation algorithm identified few patients with full DRV resistance at baseline and few patients developed full resistance at DRV failure, indicating that complete resistance to DRV is uncommon. © Springer-Verlag 2011.

Abstract

Background: To determine the health needs non-nationals, information on disease occurrence is fundamental. Goals: The goal of this study was to assess the clinical and behavioral characteristics of non-Italians with a new sexually transmitted infection (STI). Methods: Data were taken from Italy’s National STI Surveillance System (1991–1999). Results: Of the 61,798 STI cases reported from January 1991 to December 1999, 6847 (11.2%) were diagnosed among non-Italians, 47.1% of whom were Africans. Being a non-Italian patient with an STI was associated with male gender (adjusted odds ratio [AOR], 1.19; 95% confidence interval [CI], 1.11–1.27), youngest age (AOR, 1.71; 95% CI, 1.43–2.04), no formal education (AOR, 20.25; 95% CI, 17.51– 23.42), and having contracted the STI abroad (AOR, 13.98; 95% CI, 12.59 –15.54). The HIV-1 prevalence among non-Italian patients with STIs was 5.5% (95% CI, 4.9 – 6.2), with large differences by continent of origin. The highest prevalence was found among European injecting drug users (54.1%; 95% CI, 37.1–70.1), South American homosexual men (41.6%; 95% CI, 32.0 –51.8), and heterosexuals from Sub-Saharan Africa (8.9%; 95% CI, 7.2–10.8). Conclusions: Non-Italian patients with STIs seem to consist mainly of migrants, and STI transmission patterns differ from those among Italians; this information is important for developing targeted STI prevention efforts. THE MASSIVE MOVEMENT ALONG the modern migration routes represents one of the most important determinants of human health and of modifications in social status worldwide. In addition to the health implications for the migrants themselves, migration has an impact on the healthcare systems of the countries that host these persons. 1 So that these countries can better assess and satisfy the health needs of migrants, and of non-nationals in general, it is necessary to have adequate information on disease occurrence among these populations. Although such data should ideally be provided by national health surveillance systems or large multisite studies, this is rarely the case, and few national health statistics anywhere distinguish between disease cases among non-nationals and those found in the native population. 2

Abstract

An investigation was undertaken to determine whether specific pol mutations hinder long-term immune recovery regardless of virological response. In total, 826 patients with >50 HIV RNA copies/ml, who underwent genotypic resistance testing between 1 January 2000 and 31 December 2003 after >3 years of antiretroviral treatment, and were followed up for >3 years after genotypic resistance testing, were analyzed retrospectively. The outcome of the study was the lack of immune recovery after >3 years of follow-up, defined as a slope by linear regression 50 copies/ml divided by the number of HIV RNA measurements during follow-up. Logistic regression was used for univariable and multivariable analysis. Median (Q1, Q3) values at baseline were the following: age 40 (37, 45) years, years on antiretroviral therapy 4.45 (3.65, 5.47), HIV RNA 3.91 (3.39, 4.53) log 10 copies/ml, CD4+ T-cell 358 (211, 524)/μl. After 3.13 years of follow-up, 375 patients (45.4%) showed a lack of immune recovery. The risk of lack of immune recovery increased independently with increasing baseline CD4+ counts (OR=1.104 per 50-cell increase, 95% CI=1.069-1.142, P

Abstract

Understanding the determinants of virus transmission is a fundamental step for effective design of screening and intervention strategies to control viral epidemics. Phylogenetic analysis can be a valid approach for the identification of transmission chains, and very-large data sets can be analysed through parallel computation. Here we propose and validate a new methodology for the partition of large-scale phylogenies and the inference of transmission clusters. This approach, on the basis of a depth-first search algorithm, conjugates the evaluation of node reliability, tree topology and patristic distance analysis. The method has been applied to identify transmission clusters of a phylogeny of 11,541 human immunodeficiency virus-1 subtype B pol gene sequences from a large Italian cohort. Molecular transmission chains were characterized by means of different clinical/demographic factors, such as the interaction between male homosexuals and male heterosexuals. Our method takes an advantage of a flexible notion of transmission cluster and can become a general framework to analyse other epidemics. © 2011 Macmillan Publishers Limited. All rights reserved.

Abstract

Background and objectives: Guidelines indicate a plasma HIV-1 RNA load of 500-1000 copies/mL as the minimal threshold for antiretroviral drug resistance testing. Resistance testing at lower viral load levels may be useful to guide timely treatment switches, although data on the clinical utility of this remain limited. We report here the influence of viral load levels on the probability of detecting drug resistance mutations (DRMs) and other mutations by routine genotypic testing in a large multicentre European cohort, with a focus on tests performed at a viral load

Abstract

Protease inhibitor (PI)-resistant HIV-1 has hardly ever been detected at failed boosted PI-based first-line antiretroviral regimens in clinical trials. However, this phenomenon has not been investigated in clinical practice. To address this gap, data from patients starting a first-line lopinavir/ritonavir (LPV/rtv)-based therapy with available baseline HIV-1 RNA load, a viral genotype and follow-up viral load after 3 and 6 months of treatment were extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) observational database. Based on survival analysis, 39 (7.1%) and 43 (7.8%) of the 548 examined patient cases had an HIV-1 RNA >500 and >50 copies/ml, respectively, after 6 months of treatment. Cox proportional hazard models detected baseline HIV-1 RNA (RH 1.79, 95%CI 1.10-2.92 per 1 - log10 increase, P = 0.02) and resistance to the nucleoside backbone (RH 1.04, 95%CI 1.02-1.06 per 10-point increase using the Stanford HIVdb algorithm, P < 0.001) as independent predictors of HIV-1 RNA at >500 copies/ml, but not at the >50 copies/ml cutoff criteria. Higher baseline viral load, older patient age, heterosexual route of infection and use of tenofovir/emtricitabine were predictors of failure at month 3 using the 50-copy and/or 500-copy threshold. Resistance to LPV/rtv did not occur or increase in any of the available 36 follow-up HIV-1 genotypes. Resistance to the nucleoside backbone (M184V) developed in four cases. Despite the likely differences in patient population and adherence, both the low rate of virological failure and the lack of development of LPV/rtv resistance documented in clinical trials are thus confirmed in clinical practice.

Abstract

Objectives: To test retrospectively the ability of four freely available rules-based expert systems to predict short- and medium-term virological outcome following an antiretroviral treatment switch in pre-treated HIV-1 patients. Methods: The HIV-1 genotype interpretation systems (GISs) HIVdb, ANRS, Rega and AntiRetroScan were tested for their accuracy in predicting response to highly active antiretroviral therapy using 8 week (n = 765) and 24 week (n = 634) follow-up standardized treatment change episodes extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) database. A genotypic sensitivity score (GSS) was derived for each genotype-treatment pair for the different GISs and tested as a predictor of virological treatment outcome by univariable and multivariable logistic regression as well as by receiver operating characteristic curve analysis. The two systems implementing drug potency weights (AntiRetroScan and Rega) were evaluated with and without this correction factor. Results: All four GSSs were strong predictors of virological treatment outcome at both 8 and 24 weeks after adjusting for baseline viro-immunological parameters and previous drug exposure (odds ratios ranging from 2.04 to 2.43 per 1 unit GSS increase; P < 0.001 for all the systems). The accuracy of AntiRetroScan and Rega was significantly increased by drug potency weighting with respect to the unweighted versions (P ≤ 0.001). HIVdb and ANRS also increased their performance with the same drug potency weighting adopted by AntiRetroScan and Rega, respectively (P < 0.001 for both analyses). Conclusions: Currently available GISs are valuable tools for assisting antiretroviral treatment choices. Drug potency weighting can increase the accuracy of all systems. © The Author 2009.

Abstract

Background HIV-1 genotypic susceptibility scores (GSSs) were proven to be significant prognostic factors of fixed time-point virologic outcomes after combination antiretroviral therapy (cART) switch/initiation. However, their relative-hazard for the time to virologic failure has not been thoroughly investigated, and an expert system that is able to predict how long a new cART regimen will remain effective has never been designed. Methods We analyzed patients of the Italian ARCA cohort starting a new cART from 1999 onwards either after virologic failure or as treatment-naïve. The time to virologic failure was the endpoint, from the 90th day after treatment start, defined as the first HIV-1 RNA > 400 copies/ml, censoring at last available HIV-1 RNA before treatment discontinuation. We assessed the relative hazard/importance of GSSs according to distinct interpretation systems (Rega, ANRS and HIVdb) and other covariates by means of Cox regression and random survival forests (RSF). Prediction models were validated via the bootstrap and c-index measure. Results The dataset included 2337 regimens from 2182 patients, of which 733 were previously treatment-naïve. We observed 1067 virologic failures over 2820 persons-years. Multivariable analysis revealed that low GSSs of cART were independently associated with the hazard of a virologic failure, along with several other covariates. Evaluation of predictive performance yielded a modest ability of the Cox regression to predict the virologic endpoint (c-index≈0.70), while RSF showed a better performance (c-index≈0.73, p < 0.0001 vs. Cox regression). Variable importance according to RSF was concordant with the Cox hazards. Conclusions GSSs of cART and several other covariates were investigated using linear and non-linear survival analysis. RSF models are a promising approach for the development of a reliable system that predicts time to virologic failure better than Cox regression. Such models might represent a significant improvement over the current methods for monitoring and optimization of cART.

Abstract

In 2012, we conducted a retrospective cross-sectional study to assess the number of people living with HIV linked to care and, among these, the number of people on antiretroviral therapy. The health authority in each of the 20 Italian Regions provided the list of Public Infectious Diseases Clinics providing antiretroviral therapy and monitoring people with HIV infection. We asked every Public Infectious Diseases Clinic to report the number of HIV-positive people diagnosed and linked to care and the number of those on antiretroviral therapy during 2012. In 2012, 94,146 people diagnosed with HIV and linked to care were reported. The majority were males (70.1%), Italians (84.4%), and aged between 25 and 49 years (63.4%); the probable route of transmission was heterosexual contact in 37.5% of cases, injecting drug use in 28.1%, and male-to-male contact in 27.9%. Among people in care, 20.1% had less than 350 CD4 cells/μl, 87.6% received antiretroviral therapy, and among these, 62.4% had a CD4 cell count higher than 350 cells/μl. The overall estimated prevalence of individuals diagnosed and linked to care in 2012 in Italy was 0.16 per 100 residents (all ages). Adding the estimated proportion of undiagnosed people, the estimated HIV prevalence would range between 0.19 and 0.26 per 100 residents. In Italy, the majority of people diagnosed and linked to care receive antiretroviral therapy. A higher prevalence of individuals diagnosed and linked to care was observed in Northern Italy and among males. More information for developing the HIV care continuum is necessary to improve the entire engagement in care, focusing on test-and-treat strategies to substantially reduce the proportion of people still undiagnosed or with a detectable viral load.

Abstract

Background: The objective of this study was to evaluate the performance of a combined approach of liquid-based anal cytology and human papillomavirus (HPV) testing in predicting patients who should undergo high-resolution anoscopy for the early detection of anal cancer and anal intraepithelial neoplasia (AIN)-2+., Methods: We conducted a prospective single-center quality improvement study. We consecutively enrolled men who had sex with men (MSM) attending our sexually transmitted disease clinic to undergo anal Papanicolaou (Pap) and HPV tests. All patients with an abnormal anal Pap test result and/or positive HPV test result underwent high-resolution anoscopy., Results: We enrolled 217 MSM, 80 HIV-positive patients, and 137 HIV-negative patients. Cytology showed a sensitivity of 100%, a specificity of 64.1%, an accuracy of 66.7%, a positive predictive value (PPV) of 15.7%, and a negative predictive value (NPV) of 100% for the detection of AIN-2+. The high-risk (HR)-HPV test showed sensitivity, specificity, accuracy, PPV, and NPV of 100%, 36.4%, 40%, 9.4%, and 100%, respectively. The combination of abnormal cytology with identification of infection by at least 1 HR-HPV strain on the HPV test had a sensitivity of 100%, a specificity of 73%, an accuracy of 74.6%, a PPV of 19.1%, and an NPV of 100%., Conclusion: Anal HR-HPV testing, complementary to cytology, improves the diagnostic accuracy of screening for anal cancer., Competing Interests: Conflict of Interest and Sources of Funding: The authors declare that they have no commercial or other associations that might pose conflicts of interest., (Copyright © 2022 American Sexually Transmitted Diseases Association.

Abstract

The autogenous tooth transplantation approach to replace missing teeth has been in use for a long time. Different surgical techniques have been developed to improve prognosis and longevity of transplanted teeth with complete root formation. Many factors reportedly affected short- and long-term success of the procedure: complications such as ankylosis and root resorption up to the tooth exfoliation have occurred frequently. Several studies have appeared on this issue over the years. However, outcomes of transplantations have not yet been conclusively determined as no randomized clinical trials have been published on this issue, and their effectiveness has been evaluated only in observational studies. On the other hand, interesting information from specific experimental studies on the healing pattern of the interface between the root surface and alveolar bone in the replantation/transplantation model, and from non-related studies dealing with mechanically induced periodontal trauma, has been available and potentially useful since the 1970s to 1980s. However, this information has not been incorporated into clinical literature regarding tooth autotransplantation. This commentary aims to show how information from related and unrelated experimental models was translated to a clinical setting and led to a novel approach, successfully applied, in the autotransplantation of a multirooted tooth with completed root formation.

Abstract

Background: The aim of this work was to evaluate the role of human papillomavirus (HPV) testing and anal cytology, considering a population of HIV-positive and negative men who have sex with men (MSM), at high risk of sexually transmitted diseases (STD), in order to ascertain which of the methods examined is the best screening strategy for the prevention of anal cancer., Methods: In the period 06/2013-07/2014 at the "MTS Centre" of the University of Florence, 87 male patients, homo/bi-sexual, of which 46 HIV-negative and 41 HIV-positive, were recruited for anal Pap smear and HPV testing. All patients with an "abnormal" cytological result underwent anoscopy with possible biopsy., Results: HPV testing was positive in 73 patients (83.6%). Cytology was negative in 50 patients (57.5%), inconclusive in 14 patients (16.1%), abnormal in 23 patients (26.4%): 14 ASC-US (19.2%), 4 ASC-H (5.5%), 5 L-SIL (6.8%), 0 H-SIL. Anoscopy with biopsy led to diagnosis of AIN I in 10 cases, of which 6 ASC-US+ and 4L-SIL+, AIN II in only 1 case, LS-IL+., Conclusions: Anal HPV testing, when used in primary screening, lead to a high number of "false positives", given the too high prevalence of HPV infection in MSM, the highest risk population targeted for screening. So we propose a screening program with anal cytology which has a high sensitivity for detection of AIN while is a poor predictor of the severity of these lesions; therefore, all patients with abnormal anal Pap smear should undergo anoscopy with biopsy.

Abstract

Background: Over the last years the number of sexually transmitted diseases has greatly increased. This can be attributed mainly to less rigidity in the gender role and to the ever growing sexual liberalization. Sexuality today as in the past, represents an important and complex dimension of the human being. With respect to the psychological area many authors think that there are specific personality traits that to a higher extent compared to others might push individuals to carry out inconsiderate behavior among which there has been found a higher risk of sexually transmitted diseases (STD). In the present paper preliminary data of a research carried out provides information about sexual habits among patients of the IST of Florence., Methods: A sample of 344 individuals, from 15 to over 70-year-old, Italians and strangers, has been asked to fill up a self-administered questionnaire., Results: Through these data the psychological aspects at the base of sexual habits in our reference sample are highlighted even more clearly. Through the analysis of these data it will be possible to get a larger number of information that can be used for the building of psychological support experiences that take into account the individual differences among patients one finds through consultations and support., Conclusions: The psychological support is very important for a lot of patients who belong to the center and show inappropriate sexual behavior and exposed to risky sexual behavior.

Abstract

Aim: The aim of this study was to assess the demographic, behavioral and clinical features associated with newly diagnosed sexually transmitted infections (STIs) among attendees from four STI Clinics during 2011 in Tuscany, Central Italy., Methods: Electronic and non-electronic medical records of attendees were reviewed to collect socio-demographical and anamnestic characteristics of patients, and to assess the annual incidence and distribution of STIs., Results: The study included 1293 subjects, for a total number of 1394 newly diagnosed STIs. The male/female ratio was about 2:1, and Italian nationality accounted for 84.1% of the sample. MSM represented the 25.9% of the male population. Condom use was very poor in the large majority of our sample. Genital warts and non-gonococcal cervicitis and urethritis were the most frequent STIs. Anamnestic STIs were recorded in 350 subjects. When stratified for sexual preference, men who have sex with men were found at four to ten fold increased risk for syphilis, gonorrhoeae and HIV infection. New diagnoses of syphilis, gonorrhoea, urethritis and molluscum were strictly associated with infections by the same pathogens in the past (re-infections)., Conclusions: Results show that STIs in Tuscany involve a mixed young to adult population, composed by both heterosexual and homosexual subjects who practice unprotected sex and do not seem to be conscious of the associated risks, as demonstrated by the high rates of coinfections and reinfections. These findings reinforce the need for greater education and prevention efforts for HIV and other STIs among the Tuscan population.

Abstract

The aim of this study was to review recent randomized clinical trials (RCTs) dealing with the effectiveness of various modalities of orthopaedic/orthodontic expansion of maxillary arches with crossbite and the associated 6 month post retention stability. The study selection criteria included RCTs involving subjects with maxillary deficiency with crossbite, with no limits of age. The authors searched the following electronic databases from 1999 to January 2011: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, LILACS, and WEB of SCIENCE. The search strategy resulted in 12 articles meeting the inclusion criteria. Most of the studies did not meet major methodological requirements; some studies were not relevant because of small sample size, possible bias and unaccounted for confounding variables, lack of blinding in measurements, and deficient statistical methods. Treatment outcomes were different depending on the appliance used, tooth tissue-borne/tooth-borne expanders, bonded semi-rapid maxillary expansion (SRME), or rapid maxillary expansion (RME); in any case, methodological flaws prevent any sound conclusion. Stable results have been measured at the 6 month follow-up after removal of the retention plate in the treated groups in the maxillary intermolar and intercanine distances. Long-term stability results should be assessed. The Consolidated Standards of Reporting Trials (CONSORT) Statement could be helpful in improving the reporting of RCTs.

Abstract

Conventional therapies for genital warts, the clinical expression of low-risk human papillomavirus (HPV) anogenital infection, are not targeted antiviral therapies, but either attempt physical removal of the lesion or induce inflammation and a bystander immune response. Moreover, very few of the current treatments have been tested by rigorous blinded, randomized controlled trials. Therefore, official recommendations are often associated with unsatisfactory response rates and high recurrence rates. It is the purpose of this review to provide a brief overview of the genital wart treatment literature to expand awareness of the options available to practitioners faced with patients presenting with this disease. Particular attention will be paid to unconventional and complementary therapies (the so called "off-label" treatments) among which photodynamic therapy has been recently introduced as a promising strategy to both guarantee clearance of the lesion and eradication of the virus itself. Mechanisms of action of PDT are discussed together with a summary of clinical and experimental available evidences.

Abstract

Proctitis is a common problem and is most frequently associated with inflammatory bowel diseases (IBD). However, in the last ten years the incidence of infectious proctitis appears to be rising, especially in men who have sex with men. This may be due to the rise of people participating in receptive anal sex as well as the increase in sexually transmitted infections, such as those from Chlamydia trachomatis, Neisseria gonorrhoeae, Herpes simplex virus and Treponema pallidum. Recent outbreaks of lymphogranuloma venereum among homosexual men throughout Europe highlight the need to consider sexually transmitted infections in the differential diagnosis of proctitis. Symptoms of infectious proctitis can include rectal blood and mucous discharge, anorectal pain, aphtous ulcers and, sometimes, generalized lymphadenopathy and fever. A careful history and physical examination are crucial in establishing a diagnosis, eventually supported by endoscopy, histology, serology, culture and PCR. Treatment with antibiotics or antivirals is usually initiated, either empirically or after establishing a diagnosis. Coinfections, HIV testing, and treatment of sexual partners should always be considered.

Abstract

Aim: Sexually transmitted infections (STIs) are increasing worldwide, mostly due to changing sexual behavior s (larger numbers of sexual partners, concurrent relationships, increasing proportion of adolescents engaging in sexual intercourse at young age, and inconsistent condom use with new partners). In Italy, few data are available about STI spread, since most infections are not subjected to mandatory notification., Methods: In this article, the occurrence of STIs in a random sample attending a STI Unit in Florence, Italy, is reported. Results were obtained through the administration of an anonymous questionnaire that patients could complete spontaneously in the waiting room while waiting for the visit. Self-reported questions allowed to collect information about socio-demographic and clinical data, sexual behavior and perception of risk., Results: Overall, 469 patients (321 males, 148 females) participated in the study. Age ranged from 16 to 70 years. Male patients who referred to engage sexual intercourse with men (MSM) were 133; females who had sex with women (FSF) were 5, while 24 patients declared to have sex with both males and females (bisexual); 59.7% (N.=280) of participants reported they had a stable relationship, but 20% of these reported they had had sex with more than five partners during the last 12 months. The use of condoms is declared to be very infrequent, especially in the two extreme age ranges. Fifty percent of patients had been diagnosed an STI in their life, particularly syphilis (39.3%), genital warts (64.6%) and chlamydial infections (42.9%). Among those subjects who had contracted an STI (including non-curable viral infections, i.e., HIV and herpes genitalis) 32.4% referred they never used condoms., Conclusion: The authors discuss their results compared to the existing literature, and focus on identification of risk factors associated with self-reported STIs. Although conducted on a small population, this study provides a basis for targeting prevention and control strategies on our high-risk patients.

Abstract

It's difficult to establish the real risks associated with all forms of oral sex and the contribution they may make to the overall number of newly diagnosed cases of sexually transmitted infections (STIs). This article reviews the literature on the role of oral sex in the transmission of STIs and the corresponding clinical presentations. Oral sex is becoming a common sexual practice between both heterosexual and homosexual couples because it is seen as a safer alternative to penetrative sex and a safer challenge to an individual's hidden identity. Because of the frequency with which oral sex occurs, and the rarity with which it is protected, oral sex may raise justified alarming attention to underestimated orally acquired STIs.
