Abstract
17037 Background: Previous studies have indicated that, in combination with cisplatin (cis), fixed dose rate gemcitabine (gem) may be more efficacious than standard infusion gem. This open-label, randomized, multicenter Phase II study (B9E-LA-S350) was aimed to compare the efficacy and safety of these regimens as treatment for advanced NSCLC in Latin American patients (pts). Methods: Major eligibility criteria included histologic/cytologic diagnosis of stage IIIB/IV NSCLC not amenable to curative surgery; and at least one measurable lesion. Pts were randomized to receive up to 6 cycles of treatment with cis 75 mg/m2 on Day 1 plus either gem 1000 mg/m2 over 30 min on Days 1 and 8 of a 21-day cycle (standard arm) or gem 1000 mg/m2 at a fixed dose rate of 10 mg/ m2/min on Days 1 and 8 of a 21-day cycle (FDR arm). The primary endpoint was the objective response rate (ORR; assessed by RECIST criteria) and secondary endpoints included overall survival (OS), progression-free survival (PFS), duration of tumor response (TR), and toxicity. Results: The results from this interim analysis assessed all objectives. Sixty-four pts were randomized to treatment (N = 33 standard arm; N = 31 FDR arm): 22 females; mean age 60 ± 9 yrs; 20% stage IIIB, 80% stage IV. In the standard arm, 9 (27%) pts responded (CR or PR) compared to 6 (20%) pts in the FDR arm (Odds ratio: 0.67, 95% CI 0.21–2.2, p = .56). As shown in the table below, there were no statistically significant differences in median ORR, OS, PFS, TR times, and Grade (G) 3/4 toxicities. Conclusions: The standard and FDR gem and cis treatment regimens produced similar results for both efficacy and toxicity in this patient population. This trial does not support the use of a FDR administration of gem in Latin American pts with NSCLC. [Table: see text] [Table: see text]

Abstract
Apert Syndrome, also called acrocephalosyndactylia type 1, is characterized by craniostenosis with early fusion of sutures of the vault and/or cranial base, associated to mid-face hypoplasia, symmetric syndactylia of the hands and feet and other systemic malformations. CNS malformations and intracranial hypertension are frequently observed in these patients. Early surgical treatment aims to minimize the deleterious effects of intracranial hypertension. Fronto-orbital advancement, the usual surgical technique, increases the intracranial Volume and improves the disposition of encephalic structures previously deformed by a short skull. This study analyzes CNS alterations revealed by magnetic resonance in 18 patients presenting Apert Syndrome, and the conformational alterations in the encephalic structures after surgical treatment. The patients' age in February 2001 ranged from 14 to 322 Months (m=107). Image study included brain magnetic resonance showing ventricular enlargement in five cases (27.8%), corpus callosum hypoplasia in five cases (27.8%), septum pellucidum hypoplasia in five cases (27.8%), cavum vergae in two cases (11.1%) and, arachnoid cyst in the posterior fossa in two cases (11.1%). Absence of CNS alterations was noted in 44.4% of cases. A corpus callosum morphologic index was established by dividing its height by its length, which revealed values that ranged from 0.4409 to 1.0237. The values of this index were correlated to the occurrence or absence of surgical treatment (p=0.012; t=2.83). Data analysis allowed the conclusion that the corpus callosum morphologic measure quantified the conformational alterations of the cerebral structures determined by the surgical treatment.

Abstract
BACKGROUND The optimal treatment regimen for eradication of Helicobacter pylori in patients with duodenal ulcer has yet to be determined. Based on a search of MEDLINE, no studies have been performed comparing a proton pump inhibitor-based triple therapy regimen with a ranitidine bismuth citrate (RBC)-based dual therapy regimen, both containing clarithromycin. OBJECTIVE This study was undertaken to compare the efficacy of lansoprazole (LAN)-based triple therapy with that of RBC-based dual therapy in H pylori-infected patients with duodenal ulcer. METHODS Patients were randomized to receive either 1 week of triple therapy with LAN 30 mg BID, clarithromycin 500 mg BID, and tinidazole 500 mg BID, followed by 3 weeks of LAN 30 mg BID, or 2 weeks of dual therapy with RBC 400 mg BID plus clarithromycin 500 mg BID, followed by 2 weeks of RBC 400 mg BID. Eradication of H pylori was defined as negative results on both the urease quick test and histologic examination > or =4 weeks after the end of treatment. Duodenal healing and recurrence rates were assessed endoscopically at 8 weeks and 6 months. A per-protocol (PP) analysis was conducted for each efficacy end point. Also conducted were an intent-to-treat (ITT) analysis in which patients with missing data were considered failures, and an observed analysis (OBS), which included patients with an evaluable result after treatment, regardless of compliance. RESULTS One hundred eighty-five patients (126 men, 59 women; age range, 18-76 years; mean age, 43 years) were enrolled and randomized to treatment. In the LAN and RBC groups, respectively, H. pylori eradication rates were 92.6%, 93.1%, and 72.8% versus 78.6%, 77.9%, and 64.5% in the PP (P = 0.02), OBS (P = 0.01), and ITT analyses. The corresponding duodenal ulcer healing rates were 98.6%, 98.7%, and 83.7% versus 90.8%, 91.5%, and 81.7%; these differences were not statistically significant. Side effects were mild, occurring in 20.7% of LAN patients and 17.2% of RBC patients. Ulcer recurred in 2 RBC patients. No difference was observed between treatments in terms of the occurrence of gastritis or improvement of symptoms. CONCLUSION Based on the results of the PP and OBS analyses, LAN-based triple therapy was superior to RBC-based dual therapy for the eradication of H. pylori in patients with duodenal ulcer.

Abstract
Opportunist infections involving Candida albicans often develop in HIV-positive patients and oral lesions tend to become more frequent as the disease progresses. Previous studies have shown contrasting results concerning the variability of the pulsed-field gel electrophoresis (PFGE) subtypes of C. albicans observed in HIV-positive patients. Carriage of C. albicans was determined by an oral rinse technique; 41 strains of C. albicans (78% serotype A and 22% serotype B) were isolated. There was a direct correlation between candidal load (cfu/ml) and the blood HIV load, whereas there was an inverse correlation with the stage of disease and the CD4 cell counts. The PFGE patterns of isolates were variable with regard to the number and positions of bands. The variability of the band sizes in some run positions showed a Gaussian distribution. Generally, the most frequent size variants were associated with the strains with the highest cfu/ml and lowest CD4 counts (< or =200 cells/microl). These findings suggest a possible strain selection over time during disease progression, especially in HIV-positive subjects with low CD4 counts.

Abstract
To our knowledge, no studies have previously been carried out on the heterogeneity and intrafamily colonization of impetigo Staphylococcus aureus strains obtained by powerful discriminating methods such as pulsed-field gel electrophoresis (PFGE). To explore this topic, macrorestriction patterns of S. aureus strains were analyzed after SmaI and SgrAI digestion. The two enzymes provided superimposable results. A total of ninety-seven S. aureus strains was found in the 26 families whose lesions and nasal and pharyngeal samples were examined. There were 39 strains which were different by PFGE, and of these, 24 were found in the lesions. Although 85% of impetigo patients showed nasal colonization and 58% showed pharyngeal colonization, only 54% of the patients had the same PFGE strain in the lesion and in the nose, and 35% in the lesion and the pharynx. In half of the 26 families, at least one member (mother, father, or relative) presented a S. aureus strain identical, by PFGE, to strains isolated in patients' lesions. Nineteen percent of mothers, 15% of fathers, and 19% of the other relatives presented nasal colonization with strains identical to those isolated in the children's lesions. Lesional strains showed higher antimicrobial resistance than nonlesional isolates.

Abstract
PFGE has been extensively used to obtain a reliable intra-species differentiation, although this technique has not been completely standardized. In this study, PFGE was applied to analyze in detail the patterns of 19 lesional S. aureus strains isolated from patients with impetigo, compared with 15 non-lesional strains isolated from nasal or pharyngeal swabs of the same patients. The strain DNA was extracted and processed as previously reported, using the strictest protocol to limit the variations between different analytical sets. To obtain maximum sensitivity and comparability, the electrophoresis patterns were analyzed by an automated and computerized reader (GelDoc1000). The DNA fragments (range 12-15 bands) obtained for each individual strain were then divided into 39 zones including from 1 to 4 bands for a total of at least 91 possible different gel positions. The positivity for each zone (and/or the positivity for the individual bands contained) was associated with the lesional/non-lesional origin and with the face localization of the strains.

Abstract
Contrasting data are reported in the literature on the percent positivity rates (13.5%-100%) of exfoliative toxin (ET) production by S. aureus strains isolated from impetigo patients in Japan and in France. In the present study, by means of a recently available latex-test, toxin-A (ETA) or toxin-B (ETB) production was found in 67.6% of the 34 S. aureus strains isolated from 19 lesional (63.2%) and 15 non-lesional (nose or pharynx, 73.3%) areas of patients with impetigo (with no significant difference between the lesional and non-lesional isolates). ETA + ETB were produced by 44.1% of the strains, while 32.4% were non-producers. In contrast, the percent positivity rate observed in 40 [20 lesional and 20 non-lesional (nose or pharynx)] strains isolated in patients with atopic dermatitis was 15.0% (p < 0.001 both for the lesional and non-lesional strains versus impetigo, with no significant difference between lesional and non lesional strains). Finally, 26 strains from other types of specimens (abscesses, hemocultures, urine, central venous catheters, bronchoalveolar lavages) showed an 11.5% production rate of ETA or ETB (p < 0.001 versus impetigo strains, no significance versus atopic dermatitis). These data point to a significant association between exfoliative toxin production and S. aureus strains isolated in impetigo, both in lesional areas and in nasal/pharyngeal reservoirs. An attempt to correlate SmaI pulsed-field gel electrophoresis (PFGE) restriction patterns and exfoliative toxin production showed no significant association in either group.

Abstract
In 1997, prevalence of and risk factors for hepatitis A virus (HAV) infection were evaluated in 146 homosexual and 286 heterosexual men attending a Sexually Transmitted Disease (STD) Clinic in Rome, Italy. Total HAV antibody (anti-HAV) was detected in 60.3% of homosexuals and 62.2% of heterosexuals. After adjustment for the confounding effects of age, years of schooling, number of sexual partners, use of condoms, and history of STD, homosexuals were not found to be at increased risk of previous HAV exposure than heterosexuals (OR 1.1; 95% CI 0.7-1.9). Independent predictors of the likelihood of anti-HAV seropositivity among homosexuals and heterosexuals were: age older than 35 years and positive syphilis serology which is likely a proxy of lifestyles that increase the risk of faecal-oral infections. These findings do not support a higher risk in homosexual men but could suggest a role for the vaccination of susceptible patients attending STD clinics.

Abstract
The aim of this study was to establish the serological prevalence of anti-human Parvovirus B19 (HP-B19) antibodies in a group of 321 patients attending a Centre for Sexually Transmitted Diseases (STDs) and epidemiologically examine whether this virus may also be sexually transmitted. For this purpose, the serum prevalence of anti-HP-B19 evaluated in STD patients (39%) was compared with that of 164 healthy blood donors (10%, p < 0.001), using commercially available ELISA methods detecting the anti-VP1 reactivity of the sera. The same STD patients were also analyzed for serum reactivities against 4 STD-causing microorganisms, namely T. pallidum (TPHA), HBV (HBcAb), HCV (HCV-Ab) and HIV (HIV-Ab), to observe possible associations with the serum anti-HP-B19 reactivity. These tests were also carried out with commercially available kits. The results suggest that the serum anti-HP-B19 antibody prevalence in patients with STDs is increased, also independently of their intravenous drug addition and varies with the reactivity pattern determined. In addition, as expected for a STD, the anti-HP-B19 prevalence is increased in homobisexual patients compared with heterosexuals.

Abstract
To assess the relative importance of ulcerative and non-ulcerative sexually transmitted disease in the transmission of HIV, a seroprevalence study was conducted on 2210 patients at the sexually transmitted diseases (STD) clinic of the S. Maria e S. Gallicano Hospital in Rome, between 1989 and 1994. Among male patients, by univariate analysis, strong predictors of HIV infection were homosexuality, sexual exposure to a HIV-positive partner, hepatitis B virus infection, and positive syphilis serology. An increased risk was estimated for patients with past genital herpes (odds ratio (OR) 3.86, 95% confidence intervals (CI) 0.40-18.2), and primary syphilis (OR 5.79, 95% CI 0.59-28.6). By multivariate analysis, a positive association was found with homosexuality (OR 6.9, 95% CI 2.9-16.5), and positive syphilis serology (OR 3.5, 95% CI 1.3-9.2). An adjusted OR of 2.41 was calculated for current and/or past genital herpes. These results, although not conclusive, suggest a role of ulcerative diseases as risk factors for prevalent HIV infection, and indicate that positive syphilis serology is an unbiased criterion for identifying individuals at increased risk of HIV infection.

Abstract
BACKGROUND No clinical study has been performed to-date to evaluate the efficacy of the dual therapy of ranitidine bismuth citrate (RBC) plus clarithromycin (C) 500 mg b.d. given for 7 days for the eradication of H. pylori. AIM To assess the eradication rates achieved by treatment with RBC 400 mg b.d. for 28 days combined with clarithromycin 500 mg b.d. for 7 days in H. pylori-positive duodenal ulcer patients. METHODS One hundred and twelve H. pylori-positive patients with endoscopically proven active duodenal ulcer were included in a multicentre, open, randomized trial. H. pylori infection was initially detected by CLO-test and histology on antral and corpus biopsies, and by 13C-urea breath test (UBT). Patients were included if at least two of the tests were positive for H. pylori infection. Patients were randomized to receive RBC 400 mg b.d. for 4 weeks combined with clarithromycin 500 mg b.d. for the first 7 days (Group A) or 14 days (Group B). A second endoscopy was performed at least 28 days after the end of therapy for the assessment of ulcer healing and H. pylori infection. Eradication was assumed if all the tests (CLO-test, histology and UBT) were negative for H. pylori. RESULTS Fifty patients in Group A and 55 in Group B were assessed for H. pylori eradication and ulcer healing. The eradication rates according to intention-to-treat analysis were 75% in Group A and 80% in Group B. Considering only those patients with evaluable data at least 28 days after the end of therapy, H. pylori eradication was achieved in 84% and 82% in Group A and B, respectively. No statistically significant difference in eradication was found between the two groups by Mantel-Haenszel test. Only one patient, in Group A, was withdrawn because of adverse events (epigastric pain and pruritus).

Abstract
Prevalence of and risk factors for hepatitis B virus (HBV) infection were determined among 252 homosexual men with no history of intravenous drug use (median age 33 years, range 18-77) treated at a sexually transmitted disease (STD) clinic in Rome. The overall prevalence of antibodies to HBV core antigen (anti-HBc) was 50.8%, a rate nearly nine times as high as the 5.8% found recently in a national sample of young male adults, aged 18-26 years, and twice as high as the 22% found in heterosexuals attending the same clinic over the same period of time. Multiple logistic regression analysis showed that the risk of anti-HBc positivity was independently associated with increasing age, five or more sexual partners in the previous year, positive HIV serology and positive syphilis serology. Lower level of schooling, lack of condom use, history of non-ulcerative STD, current or past history of genital herpes, and positive anti-HCV serology were not associated with anti-HBc positivity. These findings corroborate the importance of sexual transmission of HBV in homosexual men. Behavioural factors, such as multiple sexual partners, probably enhance the efficiency of this mode of HBV transmission.

Abstract
BACKGROUND The role of sexual transmission of hepatitis C virus (HCV) infection is still not completely understood, partly because of the lack of longitudinal studies among cohorts of HCV-negative individuals who engage in at-risk sexual behavior. GOALS To evaluate the incidence of HCV infection in a population at risk for human immunodeficiency virus type 1 (HIV-1) infection and other sexually transmitted diseases (STD) and to identify factors associated with HCV seroconversion. STUDY DESIGN A retrospective longitudinal study was carried out on a cohort of consecutive attendees of a voluntary HIV-1 testing and counseling program in a large STD center in Rome. All individuals undergoing at least two consecutive tests for HCV antibodies were enrolled. Clinical data and information on individual behavior were collected for all study participants. RESULTS Between June, 1992 and December, 1994, a total of 709 individuals (12 intravenous drug users [IDU], 244 homosexuals, and 453 heterosexual non-IDUs), initially negative for HCV antibody, were tested more than once. Among these individuals, 15 HCV seroconversions occurred. The average follow-up time was 1.25 person/years (p/y) for an incidence rate of 1.69 per 100 p/y. The incidence rates by exposure category were 39.30 per 100 p/y among IDUs, 1.37 per 100 p/y among homosexual men, and 0.97 per 100 p/y among heterosexual non-IDUs. Excluding IDUs, of the 697 STD clinic attendees engaging in at-risk sexual behavior, HIV-1-positive status tended to be associated with HCV seroconversion (relative hazard = 5.48; 95% confidence interval = 0.85-35.40). The HCV crude incidence rates among HIV-1-infected patients at enrollment was 11.5%, 4.2%, and 2.4% in those with severe, moderate, and mild levels of immunosuppression, respectively (chi-square for trend = 2.38, P = 0.1). CONCLUSIONS In this cohort, HCV infection was confirmed to be strongly associated with intravenous drug use. Nonetheless, the occurrence of two thirds of the total HCV seroconversions in non-IDU individuals engaging in at-risk behavior suggests a role of sexual practices in the transmission of the infection. Among non-IDU individuals, the risk for development of HCV infection tended to increase in those who were HIV-1 infected.
