Goals: To describe dermatologic side effects encountered during treatment of patients with chronic hepatitis C, and analyze factors predisposing to such reactions. Background: Treatment of hepatitis C virus (HCV) infection with interferon (IFN) and ribavirin is associated with a number of mucocutaneous adverse reactions that have not been adequately studied. Study: A retrospective cohort study design was used to longitudinally describe mucocutaneous drug eruptions during IFN and ribavirin therapy in HCV-infected patients. Factors predictive of mucocutaneous eruptions were analyzed by the use of Kaplan-Meier curves and Cox proportional hazard model. Results: A total of 286 HCV-infected consecutive patients were treated with one of the IFNα formulations plus ribavirin. The mean age was 51.1 years (SD 5.6). There were 6 female patients. There were 5 patients who were also infected with human immunodeficiency virus (HIV). Fifty-six percent of the patients were white, 37% were African American, and 14% were Hispanic. Twenty-one percent of all study patients developed mucocutaneous drug eruptions. The most common drug eruptions were eczematous drug eruptions (48%), seborrheic dermatitis (11%), and xerosis (8%). Dermatologic eruptions were a contributing factor in the decision to discontinue antiviral treatment in 10% of cases. Use of Pegylated IFN formulations (hazard ratio=1.86; 95% confidence interval, 1.04-3.34) and presence of HIV coinfection (hazard ratio=4.46; 95% confidence interval, 1.61-12.92) were associated with increased rate of skin reactions. Conclusions: Mucocutaneous reactions during IFN and ribavirin treatment of hepatitis C are common and are associated with HIV infection and use of Pegylated IFN.

Background: Patients with chronic hepatitis C (HCV) infection commonly have perihepatic lymph node enlargement (PLNE). We investigated the prognostic value of PLNE in the development of complicated cirrhosis and death, as well as the clinical and laboratory factors associated with the presence of PLNE in a cohort of HCV-infected veterans. Methods: Using a retrospective cohort design, we compared the rate of development of decompensated cirrhosis and/or death in a group of HCV-infected patients who did not have evidence of decompensated cirrhosis stratified by the presence or absence of PLNE. We used Kaplan-Meier survival curves. We then evaluated which factors were predictive of detection of PLNE using logistic regression. Results: A total of 131 patients were included in the study. Fifty-nine patients had PLNE and 72 patients did not. After a mean follow-up of 42 months, survival in the absence of progression to decompensated cirrhosis and/or death was not significantly different between the two groups (log-rank test, p = 0.27). The only factor predictive of progression to decompensated cirrhosis and/or death was the presence of cirrhosis at baseline (HR 13.13, 95% CI 2.21-79.41). In addition, cirrhosis was the only factor predictive of the detection of PLNE on CT scan (OR 3.09: CI 2.1-25.9). Conclusions: Presence of PLNE in patients with chronic HCV infection is strongly associated with subclinical cirrhosis. However, PLNE does not independently predict the progression of liver disease to decompensated cirrhosis and/or death in HCV-infected patients. © 2011 Springer Science+Business Media, LLC. Source

Acute coronary syndromes are a leading cause of morbidity and mortality worldwide. The mechanisms underlying the triggering of these events are diverse and include increased coronary and systemic inflammatory activity, dominant prothrombotic conditions, increased biomechanical stress on coronary arteries, variations in the coronary arterial tone, disturbed haemodynamic homoeostasis, and altered myocardial metabolic balance. There is experimental evidence that acute infections can promote the development of acute coronary syndromes, and clinical data strongly support a role for acute infections in triggering these events. In our Review, we summarise the pathogenesis of coronary artery disease and present the evidence linking acute infections with the development of acute coronary syndromes. Greater awareness of this association is likely to encourage research into ways of protecting patients who are at high risk. © 2010 Elsevier Ltd. All rights reserved. Source

Eye | Year: 2010

Purpose: To evaluate demarcation laser photocoagulation (DLP) for macula-sparing rhegmatogenous retinal detachments (RRD) with and without symptoms of posterior vitreous separation or progressive visual field defect. Methods: Retrospective, interventional, single surgeon case series of consecutive patients with RRD treated with demarcation laser photocoagulation between March 1999 and February 2008 at an academic center. The null hypothesis was that there exists no difference in the rate of progression for retinal detachment irrespective of the presence ('symptomatic') or absence ('asymptomatic') of symptoms of posterior vitreous separation or visual field defect at presentation. Results: A total of 27 eyes of 26 patients were included in the study. In all, 22 of the 27 eyes (81.4%) did not require additional treatment and remained attached during mean follow-up of 38.4 months. None of the 14 asymptomatic patients required surgery (0%) whereas 5 out of the 13 patients (38.5%) who were symptomatic at presentation required further intervention (p = 0.016): one patient required additional laser only and four patients required scleral buckling or vitrectomy. Pre- and post- DLP logMAR visual acuity was 0.15 and 0.14, respectively. Conclusion: Demarcation laser photocoagulation is an effective alternative to scleral buckling or vitrectomy for treating asymptomatic RRDs. It has a high failure rate among eyes with symptomatic RRD. © 2010 Macmillan Publishers Limited All rights reserved. Source

Objective: We evaluated whether the addition of carotid intima media thickness and plaque (CIMT-P), and a single nucleotide polymorphism on chromosome 9p21 (9p21) together improve coronary heart disease (CHD) risk prediction in the ARIC study. Methods: Ten year CHD risk was estimated using the ARIC coronary risk score (ACRS) alone and in combination with CIMT-P and 9p21 individually and together in White participants (n= 9338). Area under the receiver operating characteristic curve (AUC), model calibration, net reclassification index (NRI), integrated discrimination index (IDI) and number of individuals reclassified were estimated. Results: The AUC of the ACRS, ACRS. +. 9p21, ACRS. +. CIMT-P and ACRS. +. CIMT-P. +. 9p21 models were 0.748, 0.751, 0.763 and 0.766 respectively. The percentage of individuals reclassified, model calibration, NRI and IDI improved when CIMT-P and 9p21 were added to the ACRS only model (see manuscript). Conclusion: Addition of 9p21 allele information to CIMT-P minimally improves CHD risk prediction in whites in the ARIC study. © 2012 Elsevier Ireland Ltd. Source
