RESUMO

BACKGROUND: The prevalence of chronic hepatitis C virus (HCV) infection in the United States is ≤1%. Universal HCV screening is recommended nationwide. Here we describe our experience implementing universal HCV screening at a cancer center. METHODS: In October 2016, universal HCV screening with HCV antibody (anti-HCV) was initiated for all new outpatients. Universal screening was promoted through widespread provider education, orders in the Epic electronic health records (EHRs), SmartSets, and automated EHR reminders. The effort focused on patients with solid tumors, because universal screening in patients with hematologic malignancies was already standard practice. Primary outcomes were the proportion of patients screened and the proportion of patients with reactive anti-HCV test results linked to HCV care. The secondary outcome was the incidence of HCV-associated hepatocellular carcinoma as a second primary malignancy (HCC-SPM) in patients with a history of other cancers before HCC diagnosis. Epic's Reporting Workbench Business Intelligence tools were used. Statistical significance was defined as P<.05 on chi-square analysis. RESULTS: From April 2016 through April 2023, 56,075 patients with solid tumors were screened for HCV, of whom 1,300 (2.3%) had reactive anti-HCV test results. The proportion of patients screened was 10.1% in the 6 months before study implementation and 34.4% in the last 6 months of the study (P<.001). HCV screening was ordered using SmartSets in 39,332 (45.8%) patients and in response to automated EHR reminders in 10,972 (12.8%) patients. Most patients with reactive anti-HCV test results were linked to care (765/1,300; 59%), most with proven HCV infection were treated (425/562; 76%), and most treated patients achieved sustained virologic response (414/425; 97%). The incidence of HCC-SPMs was 15% in historical controls treated from 2011 to 2017 and 5.7% following implementation of universal screening (P=.0002). CONCLUSIONS: Universal HCV screening can be successfully implemented in cancer hospitals using an EHR-based multipronged approach to eliminate HCV and prevent HCV-associated HCC-SPMs.

RESUMO

OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent liver disease, with the highest prevalence observed in the U.S. among Hispanic/Latino adults. While physical activity and dietary behaviors have established protective associations with NAFLD and its severity, these associations have not been well-characterized in Hispanic/Latino adults. The purpose of this study was to assess the association of lifestyle behaviors with NAFLD and advanced fibrosis in US Hispanic/Latino adults. DESIGN: We selected all Hispanic/Latino adults from the 2017-2018 National Health and Nutrition Examination Survey (NHANES). NAFLD was defined as CAP ≥285 dB/m, and advanced fibrosis as liver stiffness measurements ≥8.6 kPa. Multivariate-adjusted logistic regression models assessed associations of physical activity and sedentary behavior (Global Physical Activity Questionnaire), as well as diet quality (Healthy Eating Index [HEI]-2015) and total energy intake (24-hour recall) with NAFLD and advanced fibrosis. RESULTS: In Hispanic/Latino adults, the overall prevalence of NAFLD was 41.5%, while the prevalence of advanced fibrosis among those with NAFLD was 17.2%. We found that higher levels of physical activity and high diet quality were associated with lower risk of NAFLD. Compared to those reporting on average 0 metabolic equivalent (MET) hours/week of physical activity, participants reporting high levels of physical activity (≥32 MET hours/week) had 40% lower risk of NAFLD (Adjusted OR = 0.60, 95%CI 0.38, 0.93). High diet quality (HEI-2015) was associated with a 30% lower risk of NAFLD (Adjusted OR = 0.70, 95% CI 0.51, 0.97) and 72% lower risk of advanced fibrosis (Adjusted OR = 0.28, 95% CI 0.12, 0.66), as compared to those with low diet quality. CONCLUSIONS: In this population-based study, high levels of physical activity and diet quality were associated with lower risk of NAFLD in Hispanic/Latino adults. Public health and medical professionals need to concentrate efforts on lifestyle behavior change in Hispanic/Latino adults who are at high risk for serious liver disease.

RESUMO

The association of physical activity (PA) and diet quality with non-alcoholic fatty liver disease (NAFLD) and NAFLD-related fibrosis have never been examined in a representative sample of U.S. adults using a more precise form of measuring NAFLD. The purpose of this study was to assess the associations of PA and diet quality (Healthy Eating Index [HEI]-2015) with NAFLD and a subset with advanced fibrosis (F3-4) as assessed by vibration-controlled transient elastography with controlled attenuation parameter in a representative sample of U.S. adults. This cross-sectional analysis uses data from 2017-2018 National Health and Nutrition Examination Survey. NAFLD was defined as controlled attenuation parameter ≥285 dB/m, and high likelihood of advanced fibrosis as liver stiffness measurements ≥8.6 kPa. Associations of HEI-2015 from 24-h dietary recalls and self-reported PA and sedentary behavior were estimated in multivariable-adjusted logistic regression models of NAFLD and advanced fibrosis. In 2892 adults, the prevalence of NAFLD and advanced fibrosis was 35.6% and 5.6%, respectively. We found that high adherence to U.S. dietary recommendations (highest vs. lowest HEI-2015 tertile) and more PA (middle tertile vs. lowest) were associated with reduced odds of NAFLD (Adjusted OR and 95% CI; 0.60 (0.44, 0.84) and 0.65 (0.42, 0.99), respectively). More PA was inversely associated with advanced fibrosis (Adjusted OR = 0.35, 95%CI 0.16, 0.75). Diet quality and PA are associated with reduced odds of NAFLD, and PA may be critical even for those with advanced liver disease. These behaviors should be the focus of targeted public health interventions.

RESUMO

PURPOSE: Information is limited about adherence to practice guidelines in patients with hepatitis B virus (HBV), hepatitis C virus (HCV), or HIV infection receiving anticancer treatment. METHODS: Newly diagnosed adult cancer patients were enrolled in a multicenter, prospective cohort study (SWOG S1204) during 2013-2017 to evaluate the prevalence of HBV, HCV, or HIV in patients initiating anticancer treatment. At 6 months, records of virus-positive patients were reviewed for antiviral therapy use; anticancer treatment dose reduction; and HBV reactivation (elevated viral load). Categorical variables were compared using chi-square or Fisher's exact test. RESULTS: Of 3055 enrolled patients with viral testing, 230 had chronic or past HBV, HCV, or HIV with 6-month follow-up data (chronic HBV, 15 patients; past HBV, 158; HCV, 49; HIV, 30). Twenty percent (3/15) of chronic HBV and 11% (17/158) of past HBV patients were co-infected with HCV and/or HIV. Rates of antiviral therapy use by 6 months were as follows: chronic HBV, 85% (11/13); past HBV receiving anti-B cell therapy, 60% (3/5); past HBV receiving systemic anticancer therapy without anti-B cell therapy, 8% (8/105); HCV, 6% (2/35); and HIV, 90% (19/21). Among patients with available data, anticancer treatment dose was reduced in 1 of 145 patients with past HBV and 1 of 42 with HCV. HBV reactivation occurred in 1 of 15 patients with chronic HBV; this patient was not receiving antiviral therapy. CONCLUSION: Many patients with cancer and viral infections either do not receive guideline-recommended antiviral treatment or receive antiviral treatment that is not recommended in guidelines. Further education is needed to improve adherence to guidelines.

RESUMO

BACKGROUND: Optimal hepatitis C virus (HCV) screening strategies for cancer patients have not been established. We compared the performance of selective HCV screening strategies. METHODS: We surveyed patients presenting for first systemic anticancer therapy during 2013-2014 for HCV risk factors. We estimated the prevalence of positivity for HCV antibody (anti-HCV) and examined factors associated with anti-HCV status using Fisher's exact test or Student's t test. Sensitivity was calculated for screening patients born during 1945-1965, patients with ≥ 1 other risk factor, or both cohorts ("combined screening"). RESULTS: We enrolled 2122 participants. Median age was 59 years (range, 18-91); 1138 participants were women. Race/ethnicity distribution was white non-Hispanic, 76% (n = 1616); Hispanic, 11% (n = 233); black non-Hispanic, 8% (n = 160); Asian, 4% (n = 78); and other, 2% (n = 35). Primary cancer distribution was non-liver solid tumor, 78% (n = 1664); hematologic cancer, 20% (n = 422); and liver cancer, 1% (n = 28). Prevalence of anti-HCV was 1.93% (95% CI, 1.39%-2.61%). Over 28% of patients with detectable HCV RNA were unaware of infection. Factors significantly associated with anti-HCV positivity included less than a bachelor's degree, birth in 1945-1965, chronic liver disease, injection drug use, and blood transfusion or organ transplant before 1992. A total of 1315 participants (62%), including 39 of 41 with anti-HCV, reported ≥ 1 risk factor. Sensitivity was 80% (95% CI, 65-91%) for birth-cohort-based, 68% (95% CI, 52-82%) for other-risk-factor-based, and 95% (95% 83-99%) for combined screening. CONCLUSION: Combined screening still missed 5% of patients with anti-HCV. These findings favor universal HCV screening to identify all HCV-infected cancer patients.

RESUMO

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) affects about 25% of the general population worldwide. Although epidemiology of NAFLD is well studied in the United States, there is paucity of data for the Asian Americans. Our aim was to assess the prevalence and risk factors for NAFLD among Asian Americans. METHODS: We utilized NHANES data for 2011-2016. We defined NAFLD using recently derived US-FLI. Relative risks (RRs) and population attributable fractions (PAFs) of metabolic components on atherosclerotic cardiovascular disease (ASCVD) and advanced fibrosis were calculated for Asian Americans, and these rates were compared to non-Hispanic whites. RESULTS: NAFLD prevalence was 18.3% among Asian Americans and 28.4% among non-Hispanic whites. Asian Americans with NAFLD had lower BMI and waist circumference than non-Hispanic whites with NAFLD and were less likely to have metabolic syndrome, cardiovascular disease (CVD), chronic obstructive pulmonary disease, cancer and incident ASCVD (P < 0.05). Hyperlipidaemia had the highest attributable fraction (76.6%) for risk of ASCVD among Asian Americans with NAFLD, followed by diabetes (24.0%), current smoking (9.2%), and obesity (3.7%). Advanced fibrosis in Asian American with NAFLD was independently associated with presence of type 2 diabetes (RR = 2.70, 95% CI: 1.00-7.27). CONCLUSIONS: Asian Americans have lower prevalence of NAFLD than non-Hispanic whites. However, Asian Americans with NAFLD have similar risk factors for advanced fibrosis and ASCVD than non-Hispanic Whites.

RESUMO

Annual cervical cancer screening with Papanicolaou (Pap) and human papillomavirus (HPV) testing after stem cell transplant (SCT) is recommended, but the uptake is unknown. We aimed to determine the prevalence and predictors of cervical cancer screening in patients with hematologic malignancies. We searched MarketScan Commercial Claims database for women who underwent allogeneic or autologous SCT. The primary outcome was cervical cancer screening, defined as procedures or abnormal results for HPV and/or Pap testing according administrative codes within 2 years after SCT. A multivariable logistic regression model was fitted with cancer type, SCT year, age, geographic area, insurance plan, comorbidity, and presence of graft-versus-host disease (GVHD).The study included 1484 patients; 1048 patients (70.6%) had autologous and 436 (29.4%) allogeneic SCT. Mean age was 52.5 years. Overall, 660 patients (44.5%) had screening within 2 years after SCT, 214 (49.1%) with allogeneic SCT and 446 (42.6%) with autologous SCT (P = .02). In the allogeneic SCT group, patients with GVHD had a lower rate of screening than patients without GVHD (42.5% versus 55.4%, P < .01), and GVHD was associated with lower odds of screening (odds ratio, .50; 95% confidence interval, .32 to .79). In the autologous SCT group, patients with comorbid medical conditions had a lower rate of screening than patients without comorbidity (36.0% versus 45.7%, P < .01). In both allogeneic and autologous SCT groups older patients had lower odds of screening. Cervical cancer screening rates after SCT are low, particularly in patients with GVHD, who are at significant risk of second malignancies. Future work is needed to develop strategies to increase uptake.

RESUMO

BACKGROUND & AIMS: Tumor necrosis factor (TNF) antagonists are the first-line treatment for many autoimmune diseases. However, they have been associated with reactivation of hepatitis B virus (HBV). We determined the rate of HBV reactivation and hepatotoxicity grade 3 or 4 (HT ≥3) in patients treated with an anti-TNF agent for an autoimmune disease. METHODS: We collected data from 8887 adult patients in the Kaiser Permanente Northern California database who began treatment with TNF antagonists for autoimmune diseases (dermatologic, rheumatologic, or gastrointestinal) from 2001 through 2010, followed through December 2012. We obtained data on HBV infection (52% of patients were screened for HBV before treatment), demographic features, comorbidities, and use of immunosuppressive agents. HBV reactivation was defined as 1 of the following: >1 log increase in HBV DNA, HBV DNA-positive when previously negative, HBV DNA >2000 IU/mL if no baseline level was available, or reverse seroconversion. HT ≥3 was defined according to the National Cancer Institute Common Toxicity Criteria. We performed multivariable logistic regression to identify factors associated with HT ≥3. RESULTS: Twenty-three patients tested positive for HB surface antigen (HBsAg) at baseline and 9 of these had HBV reactivation; of the 4267 patients with unknown HBV status at baseline, 2 had HBV reactivation. None of the 178 patients who were HBsAg negative and positive for the hepatitis B core antibody (anti-HBc+) had HBV reactivation. HBV reactivation occurred in 1/5 HBsAg+ patients who received prophylactic antiviral therapy and 8/18 who did not (P = .61). No one with HBV reactivation had liver failure. HT ≥3 occurred in 273 patients (2.7%), but only 3 cases were attributed to HBV. Cirrhosis was significantly associated with HT ≥3 (P < .001). CONCLUSION: In a retrospective analysis of patients treated with TNF antagonists for autoimmune diseases, we found HBV reactivation in 39% of patients who were HBsAg+ before therapy, but not in any patients who were HBsAg-negative and anti-HBc+ before therapy. Patients should be screened for HBV infection before anti-TNF therapy; HBsAg+ patients should receive prophylactic antiviral therapy, but not HBsAg-negative, anti-HBc+ patients.

RESUMO

PURPOSE OF REVIEW: To provide an update on recent studies of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in cancer patients with an emphasis on viral reactivation after cancer treatment, new antiviral therapies, and safety concerns. RECENT FINDINGS: The diagnostic criteria for HBV reactivation in patients receiving cancer therapy were revised in 2018. HBV reactivation in these patients is preventable, even with the use of new cancer therapies. HCV reactivation also has been reported in cancer patients, particularly those with hematologic malignancies, and is not a virologic condition usually associated with poor outcome. Prophylaxis to prevent HCV reactivation is not recommended because therapy with direct-acting antivirals eradicates the infection in the majority of cancer patients. SUMMARY: Cancer patients with HBV or HCV infection are at risk for viral reactivation, with many similarities between these two infections. Patients at high risk for reactivation will benefit significantly from taking oral antivirals, which will reduce the risk of HBV reactivation or prevent development of HCV reactivation following its virologic cure.

RESUMO

Diabetes occurs in 1/90 000 to 1/160 000 births and when diagnosed under 6 months of age is very likely to have a primary genetic cause. FOXP3 encodes a transcription factor critical for T regulatory cell function and mutations are known to cause "immune dysregulation, polyendocrinopathy (including insulin-requiring diabetes), enteropathy, X-linked" (IPEX) syndrome. This condition is often fatal unless patients receive a bone-marrow transplant. Here we describe the phenotype of male neonates and infants who had insulin-requiring diabetes without other features of IPEX syndrome and were found to have mutations in FOXP3. Whole-exome or next generation sequencing of genes of interest was carried out in subjects with isolated neonatal diabetes without a known genetic cause. RT-PCR was carried out to investigate the effects on RNA splicing of a novel intronic splice-site variant. Four male subjects were found to have FOXP3 variants in the hemizygous state: p.Arg114Trp, p.Arg347His, p.Lys393Met, and c.1044+5G>A which was detected in 2 unrelated probands and in a brother diagnosed with diabetes at 2.1 years of age. Of these, p.Arg114Trp is likely a benign rare variant found in individuals of Ashkenazi Jewish ancestry and p.Arg347His has been previously described in patients with classic IPEX syndrome. The p.Lys393Met and c.1044+5G>A variants are novel to this study. RT-PCR studies of the c.1044+5G>A splice variant confirmed it affected RNA splicing by generating both a wild type and truncated transcript. We conclude that FOXP3 mutations can cause early-onset insulin-requiring diabetes with or without other features of IPEX syndrome.

RESUMO

NASH is becoming increasingly common worldwide because of the growing global prevalence of obesity and consequently NAFLD. Unfortunately, the mechanism of progression of NAFLD to NASH and then cirrhosis is not completely understood. Several factors, including insulin resistance, inflammation, oxidative stress, lipotoxicity, and bile acid (BA) toxicity, have been reported to be associated with NASH progression. The release of fatty acids from dysfunctional and insulin-resistant adipocytes results in lipotoxicity, which is caused by the ectopic accumulation of triglyceride-derived toxic metabolites and the subsequent activation of inflammatory pathways, cellular dysfunction, and lipoapoptosis. Adipose tissue (AT), especially visceral AT, comprises multiple cell populations that produce adipokines and insulin-like growth factor, plus macrophages and other immune cells that stimulate the development of lipotoxic liver disease. These biomolecules have been recently linked with many digestive diseases and gastrointestinal malignancies such as hepatocellular carcinoma. This made us question what role lipotoxicity has in the natural history of liver fibrosis. Therefore, this review focuses on the close relationship between AT and NASH. A good comprehension of the pathways that are related to dysregulated AT, metabolic dysfunction, and hepatic lipotoxicity will result in the development of prevention strategies and promising therapeutics for patients with NASH.

RESUMO

BACKGROUND: Data on the incidence of adverse liver outcomes are limited for cancer patients with chronic (hepatitis B surface antigen [HBsAg]-positive/hepatitis B core antibody [anti-HBc]-positive) or past (HBsAg-negative/anti-HBc-positive) hepatitis B virus (HBV) after chemotherapy. This study was aimed at determining the impact of test timing and anti-HBV therapy on adverse liver outcomes in these patients. METHODS: Patients with solid or hematologic malignancies who received chemotherapy between 2004 and 2011 were retrospectively studied. HBV testing and anti-HBV therapy were defined as early at the initiation of cancer therapy and as late after initiation. Outcomes included hepatitis flares, hepatic impairment, liver failure, and death. Time-to-event analysis was used to determine incidence, and multivariate hazard models were used to determine predictors of outcomes. RESULTS: There were 18,688 study patients (80.4% with solid tumors). The prevalence of chronic HBV was 1.1% (52 of 4905), and the prevalence of past HBV was 7.1% (350 of 4905). Among patients with solid tumors, late identification of chronic HBV was associated with a higher risk of hepatitis flare (hazard ratio [HR], 4.02; 95% confidence interval [CI], 1.26-12.86), hepatic impairment (HR, 8.48; 95% CI, 1.86-38.66), liver failure (HR, 9.38; 95% CI, 1.50-58.86), and death (HR, 3.90; 95% CI, 1.19-12.83) in comparison with early identification. Among patients with hematologic malignancies and chronic HBV, the risk of death was 7.8 (95% CI, 1.73-35.27) times higher for persons with late initiation of anti-HBV therapy versus early initiation. Patients with late identification of chronic HBV had late or no anti-HBV therapy. Chronic HBV predicted liver failure in patients with solid or hematologic malignancies, whereas male sex and late identification were predictors for patients with solid tumors. CONCLUSIONS: Early identification correlates with early anti-HBV therapy and reduces the risk of liver failure and death in chronic HBV patients receiving chemotherapy.

RESUMO

BACKGROUND: SWOG initiated a cancer care delivery research study of virus infection rates among newly diagnosed cancer patients. This study will inform viral screening guidelines in oncology clinics. METHODS: In a first step 'vanguard' phase, we evaluated the feasibility of multiple study procedures. Site investigators were surveyed to obtain feedback on study implementation. RESULTS: Much higher enrollment occurred at sites where all physicians participated and viral testing was performed as routine practice. These procedures will be required going forward. Additional protocol changes based on site investigator input were implemented. CONCLUSION: This multistep protocol design process illustrates how cancer care delivery research studies can adapt to real-world strategies and procedures that exist at community clinics where the predominance of cancer patients are treated.

RESUMO

AIM: Immunocompromised patients can develop chronic hepatitis E virus (HEV) infection and progress to cirrhosis. Hepatitis C virus (HCV)-infected cancer patients who have received chemotherapeutic agents experience accelerated liver fibrosis progression. Our aim was to investigate the prevalence and impact of HEV seropositivity on liver-related outcomes in HCV-infected cancer patients. METHODS: As part of a prospective study of HCV-infected cancer patients conducted at our center, we investigate the characteristics associated with progression of their liver disease. RESULTS: Of the 115 patients tested, 13 (11%) were positive for HEV immunoglobulin G. HEV seropositivity was associated with advanced age (P = 0.004), race (P = 0.02), place of birth outside the USA (P = 0.021), cirrhosis (P = 0.027), history of reused needles/syringes during massive vaccination campaigns (P = 0.015) and coronary artery disease (P = 0.039). Overall, 47 (41%) of the patients had cirrhosis. Factors independently associated with cirrhosis were male sex (odds ratio [OR], 2.8; P = 0.028) and HEV seropositivity (OR, 4.1; P = 0.032). CONCLUSION: HEV seropositivity is present in 11% of HCV-infected cancer patients and seems to be associated with cirrhosis. Our results suggest that HEV screening should be implemented in HCV-infected patients with cancer.
