As a result of effective antiretroviral therapy HIV patients are living longer, and their risk of cardiovascular disease (CVD) is a growing concern. It remains unknown whether coinfection with hepatitis C (HCV) changes an HIV person's CVD risk, and how the risks compare to the general population. The objective of this study was to compare the Framingham Risk Score (FRS) and vascular age differences in persons with HIV, HCV or HIV/HCV disease to the general population.
HIV, HCV, and HIV/HCV patients with clinic visits between 2004 and 2009 were sampled from medical clinics in Rochester, NY. Uninfected persons were randomly selected from the National Health and Nutrition Examination Survey (NHANES), and individually matched on gender, race, and age. We stratified by infection group and conducted separate multivariable linear regression analyses between each infection group and the gender, race, and age matched participants from NHANES.
Rochester patients (HIV = 239, HCV = 167, HIV/HCV = 182) were compared 3 : 1 with the NHANES participants. After controlling for weight, marital status, current pharmacotherapies and the matching variables of gender, race, and age, HIV/HCV patients had a 2% higher general FRS compared with the general population (p = 0.03), and vascular age differences that were 4.1 years greater (p = .01). HCV patients had a 2.4% higher general FRS than the general population (p < .001), and vascular age differences that were 4.4 years greater (p < .001). CVD risk was elevated but not significantly different between HIV patients and the general population.
Cardiovascular disease risk is elevated among HIV/HCV and HCV infected persons compared with the general population.

- "It is expected that HIV therapy utilization was greater than HCV therapy utilization at the time of clinic visit. Other studies have reported high and/or rising use of HIV therapy, in both coinfection and monoinfection [6,11,31]. With regards to those with HIV/HCV, the majority (87%) of patients in the aforementioned HOPS study had some form of prior exposure to antiretroviral therapy . "

ABSTRACT: Few studies have explored how utilization of outpatient services differ for HIV/HCV coinfected patients compared to HIV or HCV monoinfected patients. The objectives of this study were to (1) compare annual outpatient clinic visit rates between coinfected and monoinfected patients, (2) to compare utilization of HIV and HCV therapies between coinfected and monoinfected patients, and (3) to identify factors associated with therapy utilization.
Data were from the 2005-2010 U.S. National Hospital Ambulatory Medical Care Surveys. Clinic visits with a primary or secondary ICD-9-CM codes for HIV or HCV were included. Coinfection included visits with codes for both HIV and HCV. Monoinfection only included codes for HIV or HCV, exclusively. Patients <15 years of age at time of visit were excluded. Predictors of HIV and HCV therapy were determined by logistic regressions. Visits were computed using survey weights.
3,021 visits (11,352,000 weighted visits) met study criteria for patients with HIV/HCV (8%), HIV (70%), or HCV (22%). The HCV subgroup was older in age and had the highest proportion of females and whites as compared to the HIV/HCV and HIV subgroups. Comorbidities varied significantly across the three subgroups (HIV/HCV, HIV, HCV): current tobacco use (40%, 27%, 30%), depression (32%, 23%, 24%), diabetes (9%, 10%, 17%), and chronic renal failure (<1%, 3%, 5%), (p < 0.001 for all variables). Annual visit rates were highest in those with HIV, followed by HIV/HCV, but consistently lower in those with HCV. HIV therapy utilization increased for both HIV/HCV and HIV subgroups. HCV therapy utilization remained low for both HIV/HCV and HCV subgroups for all years. Coinfection was an independent predictor of HIV therapy, but not of HCV therapy.
There is a critical need for system-level interventions that reduce barriers to outpatient care and improve uptake of HCV therapy for patients with HIV/HCV coinfection.

ABSTRACT: Successful treatment with antivirals reduces the incidence of some extrahepatic manifestations of HCV. Thus, the advent of well-tolerated and highly potent antiviral regimens might enable extension of the indication for therapy to patients at risk of developing serious extrahepatic disorders, irrespective of the severity of the underlying liver disease.

ABSTRACT: There is conflicting evidence in the literature on whether individuals with haemophilia in the USA have greater, reduced, or similar risks for cardiovascular disease as the general population. This study evaluated the prevalence of cardiovascular comorbidities among USA males with haemophilia A, relative to an unaffected general male population with similar characteristics. Males with haemophilia A and continuous insurance coverage were identified by ICD-9-CM code 286.0 (1 January 2007-31 December 2009) using the MarketScan(®) Commercial and Medicare Research Databases. Individuals with haemophilia A were exact matched 1:3 with males without a diagnosis of haemophilia A. The prevalence of cardiovascular comorbidities identified by ICD-9-CM code was determined for matched cohorts. Of the study population, 2506 were grouped in the haemophilia A cohort and 7518 in the general cohort. Proportions of individuals with haemorrhagic stroke (2.0% vs. 0.5%, P < 0.001), ischemic stroke (4.7% vs. 2.7%, P < 0.001), coronary artery disease (10.7% vs. 5.8%, P < 0.001), myocardial infarction (0.8% vs. 0.3%, P = 0.003), hypertension (22.6% vs. 15.5%, P < 0.001), hyperlipidaemia (15.9% vs. 11.9%, P < 0.001), arterial thrombosis (12.1% vs. 5.9%, P < 0.001), and venous thrombosis (4.4% vs. 1.1%, P < 0.001) were significantly greater for the haemophilia A cohort. Results were consistent across most age groups, and comorbidities appeared at an earlier age in those with haemophilia A than in the general population. Among the USA haemophilia A population cardiovascular comorbidities are more prevalent and they appear earlier in life in comparison to the general male population, suggesting the need for earlier, enhanced screening for age-related comorbidities in the haemophilia community.
