PURPOSE OF REVIEW:The purpose of this review is to summarize the prevalence and clinical implications of the isolated anti-HBc serologic profile in HIV-infected individuals. We highlight the rare but important issue of HBV reactivation in the setting of HCV therapy and describe an approach to management. RECENT FINDINGS:The isolated anti-HBc pattern, a profile that most often indicates past exposure to HBV with waning anti-HBs immunity, is found commonly in HIV-infected individuals, particularly those with HCV. Some large cohort studies demonstrate an association with advanced liver disease, while others do not. Conversely, meta-analyses have found an association between occult HBV infection (a component of the isolated anti-HBc pattern) and advanced liver disease and hepatocellular carcinoma in HIV-uninfected individuals. In HIV-uninfected individuals with anti-HBc positivity, HBV reactivation has been reported in patients receiving HCV therapy. This phenomenon is likely the result of disinhibition of HBV with HCV eradication. In HIV-infected patients, the long-term liver outcomes associated with the isolated anti-HBc pattern remain to be fully elucidated, supporting the need for large cohort studies with longitudinal follow-up. HBV reactivation during HCV DAA therapy has been well-described in HIV-uninfected cohorts and can inform algorithms for the screening and management of the isolated anti-HBc pattern in this population.

We present an unusual case of a previously healthy 74-year-old man who presented with diffuse weakness, severe myalgias, petechial palmar rash and hypotension, but without fever, altered mental status, nuchal rigidity or headache, who was ultimately found through PCR testing to have meningococcal meningitis.

New therapies offer hope for a cure to millions of persons living with hepatitis C virus (HCV) infection. HCV elimination is a global goal that will be difficult to achieve using the traditional paradigms of diagnosis and care. The current standard has evolved toward universal HCV screening and treatment, to achieve elimination goals. There are several steps between HCV diagnosis and cure with major barriers along the way. Innovative models of care can address barriers to better serve hardly reached populations and scale national efforts in the United States and abroad. Herein, we highlight innovative models of HCV care that aid in our progress toward HCV elimination.

The purpose of this study was to assess predictors of sexual and physical assault among homeless women. A multivariate, correlation design was utilized to identify independent correlates of adult physical and sexual assault. The sample consisted of 202 homeless women residing in shelters or living on the street in the Skid Row area of Los Angeles. Respondents reporting a history of child sexual abuse were almost four times more likely to report being sexually assaulted as adults and were almost two and one third times more likely to report being physically assaulted as adults. A range of factors increase homeless women's risk of adult physical and sexual victimization, including child sexual abuse, substance use, lifetime sex trade activity, and previous incarceration. It is important for homeless service providers to develop an individual risk profile for homeless women and to intervene in order to decrease their risk of re-victimization.

Functional cure, defined as durable loss of hepatitis B surface antigen (HBsAg) and hepatitis B virus (HBV) DNA suppression off therapy, is an increasingly important goal in the treatment of chronic hepatitis B. Although novel treatments aimed at achieving functional cure are being developed and tested in clinical trials, it is important to assess the perspectives of people living with HBV towards these potential treatments and their participation in HBV functional cure research. We have performed a scoping review that revealed that there is limited knowledge regarding patient perspectives of HBV functional cure research and then identified gaps in knowledge for further investigation. Our work highlights the need for further studies in patient perspectives in HBV functional cure research.

Baseline data were collected to evaluate the effectiveness of interventions on completion of the hepatitis A and B vaccine series among 664 sheltered and street-based homeless adults who were: (a) homeless; (b) recently (<1 year) discharged from prison; (c) discharged 1 year or more; and (d) never incarcerated. Group differences at baseline were assessed for socio-demographic characteristics, drug and alcohol use, sexual activity, mental health and public assistance. More than one-third of homeless persons (38%) reported prison time and 16% of the sample had been recently discharged from prison. Almost half of persons who were discharged from prison at least 1 year ago reported daily use of drugs and alcohol over the past 6 months compared to about 1 in 5 among those who were recently released from prison. As risk for HCV and HIV co-infection continues among homeless ex-offenders, HIV/HCV prevention efforts are needed for this population.

Background

Successful hepatitis C virus (HCV) treatment may reduce cardiovascular disease (CVD) risk and improve levels of CVD biomarkers produced outside the liver (nonhepatic biomarkers).

Methods

Stored serum or plasma from before and 24 weeks after end of HCV treatment (EOT) from human immunodeficiency virus (HIV)/HCV-coinfected subjects who received up to 72 weeks of peginterferon/ribavirin, 27 with and 27 without sustained virologic response (SVR) matched by race, ethnicity and sex, were tested for nonhepatic (soluble intercellular adhesion molecule-1 [sICAM-1], soluble P-selectin [sP-selectin], interleukin [IL]-6, d-dimer, and lipoprotein-associated phospholipase A2 [Lp-PLA2]) and hepatic (cholesterol and high-sensitivity C-reactive protein) CVD and macrophage activation markers (soluble CD163 [sCD163] and soluble CD14). Changes in biomarkers and their association with SVR were examined by t tests or Wilcoxon tests and regression models.

Results

Of the 54 subjects, 30 were white, 24 were black, and 44 were male. Pretreatment levels of nonhepatic biomarkers were high: sICAM-1 overall median, 439.2 ng/mL (interquartile range [IQR], 365.6-592.8]; sP-selectin, 146.7 ng/mL (IQR, 94.1-209.9), and IL-6, 2.32 pg/mL (IQR, 1.61-3.49). Thirty-seven of 52 (71%) subjects had Lp-PLA2 >235 ng/mL. Sustained virologic response was associated with decrease in sICAM-1 (P = .033) and sCD163 (P = .042); this result was attenuated after controlling for changes in the alanine aminotransferase level. At 24 weeks after EOT, 17 (63%) SVRs had Lp-PLA2 >235 ng/mL vs 25 (93%) non-SVRs (P = .021).

Conclusions

Hepatitis C virus clearance may reduce hepatic and, subsequently, systemic inflammation and CVD risk in HIV/HCV coinfection.

We compared the Framingham risk score (FRS) for 10-year coronary heart disease (CHD) risk in age- and race-matched hepatitis C virus (HCV)-infected and HCV-uninfected persons: 114,073 HCV-infected (111,436 HCV-monoinfected and 2,637 HIV/HCV-coinfected) and 122,996 HCV-uninfected (121,380 HIV and HCV-uninfected and 1,616 HIV-monoinfected) males without cardiovascular disease, diabetes, or hepatitis B. In unadjusted analyses, FRS was similar between the HCV-infected and HCV-uninfected groups [median (interquartile range, IQR) risk points 13 (10-14) vs. 13 (10-14), p=0.192]. Cholesterol levels were lower and current smoking more prevalent in the HCV groups (both HCV and HIV/HCV) compared with the uninfected groups (p<0.001 for both). Prevalence of non-FRS CHD risk factors, such as substance abuse and chronic kidney disease, in the cohort was high, and differed by HCV and HIV status. Adjusting for age, race/ethnicity, body mass index, chronic kidney disease, drug and alcohol use, and HIV status, HCV infection was associated with minimally lower FRS (β=-0.095 risk points, p<0.001), suggesting a small but significant difference in 10-year CHD risk estimation in HCV-infected as compared to HCV-uninfected persons when measuring risk by FRS. Given the complex relationship between HCV, HIV, and CHD risk factors, some of which are not captured by the FRS, the FRS may underestimate CHD risk in HCV-monoinfected and HIV/HCV-coinfected persons. HCV- and HIV/HCV-specific risk scores may be needed to optimize CHD risk stratification.

A Hepatitis C (HCV) e-Consult Direct-To-Treatment (DTT) program managed by midlevel providers was developed at the Veteran Affairs Greater Los Angeles Healthcare System (VAGLAHS) which provided remote referral and, in some, remote management of HCV. DTT patients were more likely to be initiated on HCV treatment compared to standard of care (SOC), lending support for similar programs of remote engagement in HCV care.
