Impact of Safety-Related Dose Reductions or Discontinuations on Sustained Virologic Response in HCV-Infected Patients: Results from the GUARD-C Cohort.

BACKGROUND: Despite the introduction of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, peginterferon alfa/ribavirin remains relevant in many resource-constrained settings. The non-randomized GUARD-C cohort investigated baseline predictors of safety-related dose reductions or discontinuations (sr-RD) and their impact on sustained virologic response (SVR) in patients receiving peginterferon alfa/ribavirin in routine practice. METHODS: A total of 3181 HCV-mono-infected treatment-naive patients were assigned to 24 or 48 weeks of peginterferon alfa/ribavirin by their physician. Patients were categorized by time-to-first sr-RD (Week 4/12). Detailed analyses of the impact of sr-RD on SVR24 (HCV RNA <50 IU/mL) were conducted in 951 Caucasian, noncirrhotic genotype (G)1 patients assigned to peginterferon alfa-2a/ribavirin for 48 weeks. The probability of SVR24 was identified by a baseline scoring system (range: 0-9 points) on which scores of 5 to 9 and <5 represent high and low probability of SVR24, respectively. RESULTS: SVR24 rates were 46.1% (754/1634), 77.1% (279/362), 68.0% (514/756), and 51.3% (203/396), respectively, in G1, 2, 3, and 4 patients. Overall, 16.9% and 21.8% patients experienced ≥1 sr-RD for peginterferon alfa and ribavirin, respectively. Among Caucasian noncirrhotic G1 patients: female sex, lower body mass index, pre-existing cardiovascular/pulmonary disease, and low hematological indices were prognostic factors of sr-RD; SVR24 was lower in patients with ≥1 vs. no sr-RD by Week 4 (37.9% vs. 54.4%; P = 0.0046) and Week 12 (41.7% vs. 55.3%; P = 0.0016); sr-RD by Week 4/12 significantly reduced SVR24 in patients with scores <5 but not ≥5. CONCLUSIONS: In conclusion, sr-RD to peginterferon alfa-2a/ribavirin significantly impacts on SVR24 rates in treatment-naive G1 noncirrhotic Caucasian patients. Baseline characteristics can help select patients with a high probability of SVR24 and a low probability of sr-RD with peginterferon alfa-2a/ribavirin.This study was sponsored by F.

Overall, 16.9% and 21.8% patients experienced 651 sr-RD for peginterferon alfa and ribavirin, respectively. Among Caucasian noncirrhotic G1 patients: female sex, lower body mass index, pre-existing cardiovascular/pulmonary disease, and low hematological indices were prognostic factors of sr-RD; SVR24 was lower in patients with 651 vs. no sr-RD by Week 4 (37.9% vs. 54.4%; P = 0.0046) and Week 12 (41.7% vs. 55.3%; P = 0.0016); sr-RD by Week 4/12 significantly reduced SVR24 in patients with scores <5 but not 655. Conclusions: In conclusion, sr-RD to peginterferon alfa-2a/ribavirin significantly impacts on SVR24 rates in treatment-naive G1 noncirrhotic Caucasian patients. Baseline characteristics can help select patients with a high probability of SVR24 and a low probability of sr-RD with peginter-feron alfa-2a/ribavirin

Chronic obstructive pulmonary disease and long-term mortality in elderly subjects with chronic heart failure

Chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are associated with high rates of mortality in elderly subjects. Concurrent CHF and COPD frequently occur, especially in with advancing age. This study examines long-term mortality in community-dwelling elderly subjects affected by CHF alone, COPD alone, and coexistent CHF and COPD.The study evaluated 12-years mortality in 1288 subjects stratified for the presence or absence of CHF or COPD alone, and for coexistence of CHF and COPD.Mortality, at 12 year follow-up, was 46.7% overall, 68.6% in the presence of CHF alone (p < 0.001), 56.9% in the presence of COPD alone (p < 0.01); mortality was 86.2% where CHF and COPD coexisted (p < 0.001) and was significantly higher than in CHF or COPD alone (p < 0.05). Multivariate analysis indicates that CHF (Hazard risk = 1.67, 95% confidence interval 1.15-3.27, p < 0.031) and COPD (Hazard risk = 1.27, 95% confidence interval = 1.08-1.85, p < 0.042) were predictive of long-term mortality. When CHF and COPD simultaneously occurred, the risk dramatically increased up to 3.73 (95% confidence interval = 1.19-6.93, p < 0.001).Long-term follow-up showed higher mortality among elderly subjects affected by CHF or COPD. Simultaneous presence of CHF and COPD significantly increased the risk of death. Therefore, the presence of COPD in CHF patients should be considered a relevant factor in predicting high risk of mortality

A randomized controlled trial of amantadine plus interferon-alpha 2a vs. interferon-alpha 2a alone in naive patients with chronic hepatitis C randomized according to the early virological response to interferon-alpha 2a monotherapy

BACKGROUND: An early virological response to interferon-alpha treatment is a strong predictor of sustained response, but it has never been exploited to stratify patients in clinical trials. AIM: To evaluate the efficacy of amantadine plus interferon-alpha compared with interferon-alpha alone in naive patients with chronic hepatitis C who were randomized on the basis of the early virological response to interferon-alpha. METHODS: One hundred and eighty-one patients received recombinant interferon-alpha2a (3 MU three times weekly) for 2 months and 164 were evaluated for early (i.e. month 2) virological response. Hepatitis C virus (HCV) RNA-negative patients (n = 66) were randomized to receive 3 MU of interferon-alpha three times weekly, with or without amantadine (200 mg/day); HCV RNA-positive patients (n = 98) were randomized to receive 6 MU of interferon-alpha three times weekly, with or without amantadine (200 mg/day). HCV RNA-positive patients at 6 months discontinued treatment, and all others completed 12 months. RESULTS: At month 6, HCV RNA-negative patients made up 54.2% of the interferon + amantadine group and 42.0% of the monotherapy group (P = 0.07). At month 12, HCV RNA-negative patients made up 38.5% of the interferon + amantadine group and 28.4% of the monotherapy group (N.S.). The sustained virological response rates were 21.6% and 20.9%, respectively (N.S.). CONCLUSION: The addition of amantadine does not enhance the sustained virological response to interferon-alpha in naive patients with chronic hepatitis C; however, an additive effect of amantadine occurs in the first 6 months, mainly in patients without an early response to monotherapy. Early response to interferon-alpha is a strong predictor of sustained virological response

Recurrent miscarriage and fetal congenital malformations: Is there a neglected causal association?

The aim of the present study is to investigate the correlation between pregnancies complicated by morphological or chromosomal fetal anomalies and an obstetric history of two or more pregnancy losses, analyzing the association with any maternal risk factor. Study Design: Retrospective analysis of women who had access to the Day Hospital Clinic of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome from 2012 to 2018 for a pregnancy complicated by fetal malformation and/or abnormal karyotype, and who had an obstetric history of at least one pregnancy loss. Patients were divided into four groups depending on the number of miscarriages and the presence of a genetic anomaly: Group 0 included women with &lt;2 miscarriages and fetal malformations, Group 1 included women with 2 miscarriages and fetal malformations, Group 2 included women with &lt;2 abortion, fetal malformations and the presence of genetic anomalies; Group 3 included women with 2 abortions, fetal malformations and genetic anomalies. Statistical analysis was performed using the SAS v. 9.4 (SAS Institute Inc., Cary, NC, USA). Results: A total of 466 patients were included in the present analysis. Out of these, 379 patients belonged to Group 0; 40 patients entered in Group 1; Group 2 included 42 patients, and 5 patients were part of Group 3. Pregnancies complicated by fetal congenital malformations in patients with two or more pregnancy losses were significantly associated with maternal trombophilic disease and previous birth defects. Recurrent miscarriage and fetal structural anomalies were also significantly correlated with advanced maternal age. Conclusions: An adequate periconceptional counseling regarding the risk of fetal congenital anomalies may be indicated in patients affected by thrombophilic disease, as well as in those of advanced maternal age and with a pregnancy history of fetal malformations. The screening for thrombophilia may be advisable in patients with an obstetric history of congenital birth defects

Simit epidemiological multicentric study on hospitalized immigrants in Italy during 2002

The aim of this article is to retrospectively evaluate the patient characteristics and the most common infectious diseases in immigrant patients hospitalized in 46 Italian infectious disease clinics during 2002. The main Italian infectious disease clinics were invited to fill in a questionnaire that regarded the number and type of hospital admissions, the country of origin, and demographic features (age, sex, and resident state) of immigrants. A total of 46 clinics including 2255 patients participated in the study. Most patients were men (63%) with an age between 16 and 40 years (63.4%) covered by the National Health Service (71%) and coming from Africa (44.3%). The main infectious diseases observed were: 378 (16.76%) cases of HIV infection, 303 (13.43%) cases of tuberculosis diseases, 282 (12.5%) cases of various forms of viral hepatitis, 177 (7.84%) cases of respiratory diseases, and 196 (8.69%) gastrointestinal diseases. Tropical diseases found were 134 (5.94%) including 95 cases of malaria (70.9%). In conclusion, a broad range of diseases was noted in immigrants which were directly correlated with conditions of poverty. Only a few tropical diseases were diagnosed and therefore the immigrant should not be considered as an infectious disease carrier. \ua9 Springer Science+Business Media, Inc. 2005
