Abstract
BACKGROUND Studies comparing head-to-head treatment modalities for anogenital warts are lacking. AIM We sought to compare a short, 8-week course of imiquimod 5% cream to versus the standard 4 week course of podophyllotoxin in the treatment of anogenital warts and to assess factors that may affect response to treatment. METHODS This was a retrospective cohort study. We reviewed medical files of otherwise healthy patients with a first episode of anogenital warts who were treated with either a short, 8-week course of imiquimod or the standard 4-week course of podophyllotoxin. Inverse probability of treatment weighted (IPTW). Logistic regression was employed to evaluate factors that may affect response to therapy. RESULTS The study included 347 patients. In patients with lesions on dry, keratinized anatomical sites, the complete clearance rates were 7.6% for imiquimod and 27.9% for podophyllotoxin (P < 0.001). In patients with lesions on moist, partially keratinized sites, no difference between the treatments was revealed. Significant predictors of > 50% reduction in wart area were location of lesions [odds ratio (OR) (95% confidence interval (CI)): 3.6 (1.84-7.08), P = 0.0002] for "partially keratinized" versus "keratinized" sites and treatment used [OR (95% CI): 1.79 (1.08-2.97), P = 0.024] for podophyllotoxin versus imiquimod. LIMITATIONS The retrospective design of the study was a limitation that we mitigated against with the use of IPTW logistic regression. CONCLUSION A standard 4 week course of Podophyllotoxin was more effective than an 8-week course of imiquimod only for lesions on keratinized sites. Treatment with podophyllotoxin and location of lesions on partially keratinized sites were independent predictors of >50% reduction in wart area.

Abstract
BACKGROUND The prevalence of HIV-1 drug resistance among treatment-naïve patients ranges between 8.3% and 15% in Europe and North America. Previous studies showed that subtypes A and B were the most prevalent in the Greek HIV-1 epidemic. Our aim was to estimate the prevalence of resistance among drug naïve patients in Greece and to investigate the levels of transmission networking among those carrying resistant strains. METHODS HIV-1 sequences were determined from 3428 drug naïve HIV-1 patients, in Greece sampled during 01/01/2003-30/6/2015. Transmission clusters were estimated by means of phylogenetic analysis including as references sequences from patients failing antiretroviral treatment in Greece and sequences sampled globally. RESULTS The proportion of sequences with SDRMs was 5.98% (n=205). The most prevalent SDRMs were found for NNRTIs (3.76%), followed by N(t)RTIs (2.28%) and PIs (1.02%). The resistance prevalence was 22.2% based on all mutations associated with resistance estimated using the HIVdb resistance interpretation algorithm. Resistance to NNRTIs was the most common (16.9%) followed by PIs (4.9%) and N(t)RTIs (2.8%). The most frequently observed NNRTI resistant mutations were E138A (7.7%), E138Q (4.0%), K103N (2.3%) and V179D (1.3%). The majority of subtype A sequences (89.7%; 245 out of 273) with the dominant NNRTI resistance mutations (E138A, K103N, E138Q, V179D) were found to belong to monophyletic clusters suggesting regional dispersal. For subtype B, 68.1% (139 out of 204) of resistant strains (E138A, K103N, E138Q V179D) belonged to clusters. For N(t)RTI-resistance, evidence for regional dispersal was found for 27.3% and 21.6% of subtype A and B sequences, respectively. CONCLUSIONS The TDR rate based on the prevalence of SDRM is lower than the average rate in Europe. However, the prevalence of NNRTI resistance estimated using the HIVdb approach, is high in Greece and it is mostly due to onward transmissions among drug-naïve 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
BACKGROUND Epidemiological data on primary syphilis in Greece are limited. OBJECTIVE The purpose of the present study was to investigate the trends of the disease in Greece during the last few years and whether they are in accordance with the trends in other European countries and the United States of America. METHODS We conducted a retrospective analysis based on records of patients who visited the Sexually Transmitted Infections Unit of 'A. Sygros' Hospital in Athens, Greece, during the period 2005-2012. Our hospital is a tertiary referral centre for sexually transmitted infections covering an area of more than four million people, which is almost half the population of Greece. We documented the total annual number of patients, the male to female ratio, sexual orientation, patients' ethnic origin and education level. RESULTS We reviewed the records of 1185 patients with a confirmed diagnosis of primary syphilis. The total number of patients with primary syphilis has risen from 111 in 2005 to 158 in 2012, an increase of 42.3%. The mean annual number is 148. The mean male to female ratio is 4.76 : 1, with a peak value of 8.50 : 1 in 2011. The majority of patients are of Greek origin, ranging from 67.4% to 87.2%. Within the male patients group, it seems that the percentage of men having sex with men has risen steadily from 2005 (20.7%) up to 2010 (59.1%) with a decline in 2012 (46.0%). The mean value over 8 years is 45.0%. CONCLUSION Primary syphilis in Greece is on the rise. Τhe majority of our patients are Greek, despite immigrant influx. Men clearly outnumber women, representing more than 80% of the total number of patients. Furthermore, there seems to be a trend towards predominance of men having sex with men as the core group among male patients.

Abstract
The prevalence of HIV-1 drug resistance mutations in naïve patients has been previously shown to differ greatly with the geographic origin. The purpose of this study was to prospectively estimate the prevalence of HIV-1 drug resistance in Greece by analyzing a representative sample of newly HIV-1 diagnosed patients, as part of the SPREAD collaborative study. Protease (PR) and partial reverse transcriptase (RT) sequences were determined from 101 newly diagnosed HIV-1 patients, in Greece, during the period September 2002--August 2003, representing one-third of the total newly diagnosed HIV-1 patients in the same time period. The prevalence of HIV-1 drug resistance was estimated according to the IAS-USA mutation table taking into account all mutations in RT and only major mutations in PR region. The overall prevalence of resistance was 9% [95% confidence interval (CI): 4.2--16.2%]. The prevalence of mutations associated with resistance to NRTIs was 5% (95% CI: 1.6--11.2%), for NNRTIs was 4% (95% CI: 1.1--9.8%), while no major resistance mutations were found in PR. No multi-class resistance was detected in the study population. The prevalence of resistant mutations in the recent seroconverters was 22%. For two individuals, there was clear evidence for transmitted resistance based on epidemiological information for a known source of HIV-1 transmission. The prevalence of the HIV-1 non-B subtypes and recombinants was 52%.

Abstract
Objective To assess whether differences in safety profiles between nevirapine (NVP) and efavirenz (EFV), as observed in the 2NN study, translated into differences in ‘health related quality of life’ (HRQoL). Design A sub-study of the 2NN study, with antiretro-viral-naive patients randomly allocated to NVP (once or twice daily), EFV or NVP+EFV, in addition to stavudine and lamivudine. Methods Comparing differences in changes of HRQoL over 48 weeks as measured with the Medical Outcomes Study HIV Health Survey (MOS-HIV) questionnaire, using analysis of variance. Results The 2NN study enrolled 1216 patients. No validated questionnaires were available for 244 patients, and 55 patients had no HRQoL data at all, leaving 917 patients eligible for this sub-study. A total of 471 (51%) had HRQoL measurements both at baseline and week 48. The majority (69%) of patients without HRQoL measurements did, however, complete the study. The change in the physical health score (PHS) was 3.9 for NVP, 3.4 for EFV and 2.4 for NVP+EFV ( P=0.712). For the mental health score (MHS) these values were 6.1, 7.0 and 3.9, respectively ( P=0.098). A baseline plasma HIV-1 RNA concentration (pVL) ≥100 000 copies/ml and a decline in pVL (per log10) were independently associated with an increase of PHS. An increase of MHS was only associated with pVL decline. Patients experiencing an adverse event during follow-up had a comparable change in PHS but a significantly smaller change in MHS, compared with those without an adverse event. Conclusions First-line ART containing NVP and/or EFV leads to an improvement in HRQoL. The gain in HRQoL was similar for NVP and EFV, but slightly lower for the combination of these drugs.

Abstract
The widespread use of antiviral drugs against HIV has increased the prevalence of HIV-1 resistant strains among naïve individuals due to transmission of resistant strains. The purpose of this study was to investigate the presence of HIV-1 strains harboring resistance mutations in naïve patients in Greece. Blood samples were collected from 25 individuals. The DNA sequence of protease and partial reverse transcriptase regions (codons 41-223) were obtained by direct sequencing. Our results showed the absence of any primary resistance mutations in the study population. However, we were able to identify high prevalence of sequence polymorphisms at positions in reverse transcriptase region associated mainly with resistance to NNRTIs. Moreover, in protease region several secondary mutations were detected, suggesting the higher genetic variability of this region. The clinical significance of the polymorphisms associated with reduced susceptibility to NNRTIs remains to be clarified.

Abstract
PURPOSE To determine virological and immunological response to highly active antiretroviral therapy (HAART) and to investigate factors influencing response in a community-based setting. METHOD Plasma HIV RNA levels and CD4 cell counts were studied in 168 unselected individuals starting HAART including indinavir or ritonavir or hard-gel saquinavir-containing regimens. RESULTS Overall, 60% of the patients reduced their HIV RNA to below 500 Eq/mL, but half of them experienced a subsequent virologic rebound. Patients with higher baseline HIV RNA, higher baseline CD4 cell count, and simultaneous initiation of combination therapy and patients on indinavir or ritonavir regimen were more likely to have virologic response within 6 months since HAART initiation. Patients with lower baseline CD4 cell count and with lower rates of viral clearance had a higher probability of a subsequent virologic rebound. Forty percent of the patients had increased their CD4 cell counts by more than 100 cells/microL (immunologic response). The probability of immunologic response was independent of baseline HIV RNA levels and CD4 cell count; however, the more complete the virologic suppression, the higher the probability of immunologic response. Thirty percent of the patients had discordance between virologic and immunologic responses. CONCLUSION The rate of virologic failure in this unselected group of patients was higher than that observed in randomized clinical trials, but only a minority (11%) of the patients were treatment naïve. Starting combination therapy simultaneously and initiating antiretroviral therapy before advanced HIV disease has developed predict virologic response, whereas the magnitude of viral suppression predicts mid to long immunological response.

Abstract
Recombination is one of several factors contributing to the genetic diversity of HIV-1, which is divided into group M (itself comprising 11 subtypes, A-K) and two other groups named O and N. In the present study, the full-length genome of an HIV-1 isolate obtained from a Greek subject (GR17) infected in the Democratic Republic of the Congo (formerly Zaire) was analyzed to reveal a novel mosaic sequence composed of subtypes A, G, and E and regions of indeterminate classification. In particular, most of pol and tat/vpu, as well as the region encoding intracellular domain of gp41, did not cluster with any of the previously characterized HIV-1 subtypes. The clustering of the LTR of GR17 with subtype E was suggestive of a subtype E origin of the unclassified regions. However, the identification of distinct characteristics in the LTR, such as two functional NF-kappaB sites and a distinct TAR element, compared with those of circulating (A/E) recombinants, suggests that the partial subtype E sequences found in GR17 and the mosaic viruses (A/E) have not derived from each other. These results provide evidence that parental subtype E may have existed in the geographic area of Central Africa.

Abstract
This paper compares AIDS hospital care in several European-Union countries. For this purpose hospital-care utilisation studies on inpatient days and outpatient contacts were analysed in a generic approach controlling for severity stages of AIDS. Lifetime hospital-care needs for AIDS are derived, providing useful information for health-care policy makers. In a next step, lifetime estimates are linked to estimated annual new cases of AIDS, resulting from standardised epidemiological modelling. These results on AIDS impact at the population level are reported including statistical confidence limits. Both lifetime hospital-care needs at the patient level and AIDS impact at the population level are compared between countries and related to characteristics of the national AIDS epidemics and health-care systems. A person with AIDS has a contact--either inpatient day or outpatient visit--with the hospital in 14% (UK) to 24% (France) of the days spent in the AIDS stage. Related to the national AIDS epidemics (epidemiological impact), Italy and Greece have high levels of outpatient contacts per million population. Estimated hospital-bed needs for AIDS in 1995 are up to 2.13% (in Spain) of total national acute-care hospital beds available. Estimated per-capita needs for outpatient visits in 1995 are highest in Italy, corresponding to 108 doctor full-time equivalents. In a case-study for Greece and The Netherlands, differences in hospital-care utilisation patterns were assessed to correspond with differences in their health-care systems (number of hospital beds, doctors and nurses per capita and some qualitative characteristics of medical care in both countries). International comparison of AIDS hospital care is possible using standardised analysis of national hospital-care utilisation data and standardised epidemiological modelling. Estimates of lifetime hospital-care needs are an essential input for cost-effectiveness analyses used to aid health-care policy decision-making.

Abstract
The HIV-1 subtype distribution in 83 HIV-1-seropositive individuals living in Greece was investigated by using the heteroduplex mobility assay (HMA), DNA sequencing, and phylogenetic analysis. The results revealed that partial HIV-1 gp120 sequences from 71 (86%) patients were subtype B, 5 (6%) were subtype A, 4 were subtype D (5%), 2 (2%) were subtype C, and 1 (1%) was subtype I. The subtype I isolate was documented in an intravenous drug user. A high prevalence (90-100%) of B isolates among intravenous drug users, hemophiliacs, and homosexual men was observed, in contrast to heterosexuals, among whom non-B subtypes seemed to be common (42.9%, p < 0.001). Among the Greek population subtype B is the most frequent (94%), in contrast to the high prevalence (57%) of non-B isolates found in emigrants living in Greece (p < 0.001). A heterosexual transmission case of subtype D in a Greek individual not traveling abroad was also documented. The broad HIV-1 diversity in Greece may be explained by population movements, such as migration and traveling.
