Abstract

Background The increasing global prevalence of pulmonary nontuberculous mycobacteria (NTM) disease has called attention to challenges in NTM diagnosis and management. This study was conducted to understand management and outcomes of patients with pulmonary NTM disease at diverse centers across the United States. Methods We conducted a 10-year (2005–2015) retrospective study at 7 Vaccine and Treatment Evaluation Units to evaluate pulmonary NTM treatment outcomes in human immunodeficiency virus–negative adults. Demographic and clinical information was abstracted through medical record review. Microbiologic and clinical cure were evaluated using previously defined criteria. Results Of 297 patients diagnosed with pulmonary NTM, the most frequent NTM species were Mycobacterium avium-intracellulare complex (83.2%), M. kansasii (7.7%), and M. abscessus (3.4%). Two hundred forty-five (82.5%) patients received treatment, while 45 (15.2%) were followed without treatment. Eighty-six patients had available drug susceptibility results; of these, >40% exhibited resistance to rifampin, ethambutol, or amikacin. Of the 138 patients with adequate outcome data, 78 (56.5%) experienced clinical and/or microbiologic cure. Adherence to the American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) treatment guidelines was significantly more common in patients who were cured (odds ratio, 4.5, 95% confidence interval, 2.0–10.4; P Conclusions Despite ATS/IDSA Guidelines, management of pulmonary NTM disease was heterogeneous and cure rates were relatively low. Further work is required to understand which patients are suitable for monitoring without treatment and the impact of antimicrobial therapy on pulmonary NTM morbidity and mortality.

Abstract

BACKGROUND & AIMS: Nonalcoholic fatty liver disease (NAFLD) is the most common pediatric chronic liver disease. Little is known about outcomes in recognized youth. METHODS: We compared paired liver biopsies from 122 of 139 children with NAFLD (74% male; 64% white; 71% Hispanic; mean age, 13 ± 3 years; age range, 8–17 years) who received placebo and standard of care lifestyle advice in 2 double-blind, randomized clinical trials within the nonalcoholic steatohepatitis (NASH) clinical research network from 2005 through 2015. We analyzed histologic changes with respect to baseline and longitudinal change in clinical variables using regression analysis. RESULTS: At enrollment, 31% of the children had definite NASH, 34% had borderline zone 1 NASH, 13% had borderline zone 3 NASH, and 21% had fatty liver but not NASH. Over a mean period of 1.6 ± 0.4 years, borderline or definite NASH resolved in 29% of the children, whereas 18% of the children with fatty liver or borderline NASH developed definite NASH. Fibrosis improved in 34% of the children but worsened in 23%. Any progression to definite NASH or in fibrosis occurred in 36% of the children, and both occurred in 11% of the children. Any improvement in NASH or fibrosis occurred in 52%, and both occurred in 20% of children. Type 2 diabetes developed in 5% of the cohort. Any progression to NASH and/or fibrosis was associated with adolescent age, higher waist circumference, levels of alanine or aspartate aminotransferase, total and low-density lipoprotein-cholesterol at baseline, increasing level of alanine aminotransferase, and hemoglobin A1C (P < .05). Progression to NASH and/or fibrosis were also associated with increasing level of gamma-glutamyl transferase and development of type 2 diabetes (P < .01). Increasing level of gamma-glutamyl transferase also associated with reduced odds of any improvement (P = .003). CONCLUSIONS: One-third of children with NAFLD enrolled in placebo groups of clinical trials had histologic features of progression within 2 years, in association with increasing obesity and serum levels of aminotransferases and loss of glucose homeostasis.

Abstract

To examine the distribution of birth weight in children with nonalcoholic fatty liver disease (NAFLD) compared with the general US population, and to investigate the relationship between birth weight and severity of NAFLD.A multicenter, cross-sectional study of children with biopsy-proven NAFLD enrolled in the Nonalcoholic Steatohepatitis Clinical Research Network Database. Birth weight was categorized as low birth weight (LBW), normal birth weight (NBW), or high birth weight (HBW) and compared with the birth weight distribution in the general US population. The severity of liver histology was assessed by birth weight category.Children with NAFLD (n = 538) had overrepresentation of both LBW and HBW compared with the general US population (LBW, 9.3%; NBW, 75.8%; HBW, 14.9% vs LBW, 6.1%; NBW, 83.5%; HBW 10.5%; P .0001). Children with HBW had significantly greater odds of having more severe steatosis (OR, 1.82, 95% CI. 1.15-2.88) and nonalcoholic steatohepatitis (OR, 2.03; 95% CI, 1.21-3.40) compared with children with NBW. In addition, children with NAFLD and LBW had significantly greater odds of having advanced fibrosis (OR, 2.23; 95% CI, 1.08-4.62).Birth weight involves maternal and in utero factors that may have long-lasting consequences. Children with both LBW and HBW may be at increased risk for developing NAFLD. Among children with NAFLD, those with LBW or HBW appear to be at increased risk for more severe disease.

Abstract

Iron deficiency is often observed in obese individuals. The iron regulatory hormone hepcidin is regulated by iron and cytokines interleukin (IL) 6 and IL1β. We examine the relationship between obesity, circulating levels of hepcidin, and IL6 and IL1β, and other risk factors in patients with nonalcoholic fatty liver disease (NAFLD) with iron deficiency.We collected data on 675 adult subjects (18 years old) enrolled in the Nonalcoholic Steatohepatitis Clinical Research Network. Subjects with transferrin saturation20% were categorized as iron deficient, whereas those with transferrin saturation ≥20% were classified as iron normal. We assessed clinical, demographic, anthropometric, laboratory, dietary, and histologic data from patients, and serum levels of hepcidin and cytokines IL6 and IL1β. Univariate and multivariate analysis were used to identify risk factors for iron deficiency.One-third of patients (231 of 675; 34%) were iron deficient. Obesity, diabetes, and metabolic syndrome were more common in subjects with iron deficiency (P.01), compared with those that were iron normal. Serum levels of hepcidin were significantly lower in subjects with iron deficiency (61 ± 45 vs 81 ± 51 ng/mL; P.0001). Iron deficiency was significantly associated with female gender, obesity, increased body mass index and waist circumference, presence of diabetes, lower alcohol consumption, black or American Indian/Alaska Native race (P ≤ .018), and increased levels of IL6 and IL1β (6.6 vs 4.8 for iron normal, P ≤ .0001; and 0.45 vs 0.32 for iron normal, P ≤ .005).Iron deficiency is prevalent in patients with NAFLD and associated with female gender, increased body mass index, and nonwhite race. Serum levels of hepcidin were lower in iron-deficient subjects, reflecting an appropriate physiologic response to decreased circulating levels of iron, rather than a primary cause of iron deficiency in the setting of obesity and NAFLD.

Abstract

BACKGROUND & AIMS: Noninvasive methods are needed to determine disease stage in patients with nonalcoholic fatty liver disease (NAFLD). We evaluated the diagnostic performance of several widely available fibrosis models for the assessment of hepatic fibrosis in patients with NAFLD. METHODS: We performed a retrospective analysis of data from individuals enrolled in the NIDDK NASH Clinical Research Network, from 2004 through 2018. Using biopsy as the reference standard, we determined the diagnostic performance of the aspartate aminotransferase (AST):platelet ratio (APRI), FIB-4, ratio of AST:alanine aminotransferase (ALT) and the NAFLD fibrosis score (NFS) in a cross-sectional study of 1904 subjects. The ability of these models to detect changes in fibrosis stage was assessed in a longitudinal data set of 292 subjects with 2 biopsies and accompanying laboratory data. Outcomes were detection of fibrosis of any stage (stages 0 to 4), detection of moderate fibrosis (stages 0–1 vs 2–4), and detection of advanced fibrosis (stages 0–2 vs 3–4). Diagnostic performance was evaluated using the C-statistic, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) analyses. RESULTS: In the cross-sectional study, FIB-4 and NFS outperformed other non-invasive models for detecting advanced fibrosis; the C-statistics were 0.80 for FIB-4 and 0.78 for NFS. In the longitudinal study, 216 patients had non-advanced fibrosis at baseline and 35 patients progressed to advanced fibrosis after median follow up of 2.6 years. After we adjusted for fibrosis stage and model score at initial biopsy, change in APRI, FIB-4, and NFS were significantly associated with change in fibrosis. A unit change in APRI, FIB-4, or NFS was associated with changes in fibrosis stage of 0.33 (95% CI, 0.20-0.45; P

Abstract

BACKGROUND & AIMS: Focal zone 1 steatosis, although rare in adults with nonalcoholic fatty liver disease (NAFLD), does occur in children with NAFLD. We investigated whether focal zone 1 steatosis and focal zone 3 steatosis are distinct subphenotypes of pediatric NAFLD. We aimed to determine associations between the zonality of steatosis and demographic, clinical, and histologic features in children with NAFLD. METHODS: We performed a cross-sectional study of baseline data from 813 children (age less than 18 years; mean age, 12.8±2.7 years). The subjects had biopsy-proven NAFLD and were enrolled in the NASH Clinical Research Network. Liver histology was reviewed using the Nonalcoholic Steatohepatitis Clinical Research Network scoring system. RESULTS: Zone 1 steatosis was present in 18% of children with NAFLD (n=146) and zone 3 steatosis was present in 32% (n=244). Children with zone 1 steatosis were significantly younger (10 vs 14 years; P

Abstract

OBJECTIVE:To determine the percentage of children with nonalcoholic fatty liver disease (NAFLD) in whom intervention for low-density lipoprotein cholesterol or triglycerides was indicated based on National Heart, Lung, and Blood Institute guidelines. STUDY DESIGN:This multicenter, longitudinal cohort study included children with NAFLD enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Nonalcoholic Steatohepatitis Clinical Research Network. Fasting lipid profiles were obtained at diagnosis. Standardized dietary recommendations were provided. After 1 year, lipid profiles were repeated and interpreted according to National Heart, Lung, and Blood Institute Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction. Main outcomes were meeting criteria for clinically actionable dyslipidemia at baseline, and either achieving lipid goal at follow-up or meeting criteria for ongoing intervention. RESULTS:There were 585 participants, with a mean age of 12.8 years. The prevalence of children warranting intervention for low-density lipoprotein cholesterol at baseline was 14%. After 1 year of recommended dietary changes, 51% achieved goal low-density lipoprotein cholesterol, 27% qualified for enhanced dietary and lifestyle modifications, and 22% met criteria for pharmacologic intervention. Elevated triglycerides were more prevalent, with 51% meeting criteria for intervention. At 1 year, 25% achieved goal triglycerides with diet and lifestyle changes, 38% met criteria for advanced dietary modifications, and 37% qualified for antihyperlipidemic medications. CONCLUSIONS:More than one-half of children with NAFLD met intervention thresholds for dyslipidemia. Based on the burden of clinically relevant dyslipidemia, lipid screening in children with NAFLD is warranted. Clinicians caring for children with NAFLD should be familiar with lipid management.

Abstract

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the United States. The association between NAFLD and quality of life (QOL) remains unclear. These data are important to estimate the burden of illness in NAFLD. The aim was to report QOL scores of adults with NAFLD and examine the association between NAFLD severity and QOL. QOL data were collected from adults with NAFLD enrolled in the Nonalcoholic Steatohepatitis Clinical Research Network using the Short Form 36 (SF-36) survey, and scores were compared with normative U.S. population scores. Liver biopsy histology was reviewed by a central pathology committee. A total of 713 subjects with NAFLD (male = 269, female = 444) were included. Mean age of subjects was 48.3 years; 61% had definite nonalcoholic steatohepatitis (NASH), and 28% had bridging fibrosis or cirrhosis. Diabetes was present in 27% of subjects. Subjects with NAFLD had worse physical (mean, 45.2) and mental health scores (mean, 47.6) compared with the U.S. population with (mean, 50) and without (physical, 55.8; mental, 52.5) chronic illness. Subjects with NASH reported lower physical health compared with subjects with fatty liver disease without NASH (44.5 versus 47.1, P = 0.02). Subjects with cirrhosis had significantly (P < 0.001) poorer physical health scores (38.4) than subjects with no (47.6), mild (46.2), moderate (44.6), or bridging fibrosis (44.6). Cirrhosis was associated with poorer physical health after adjusting for potential confounders. Mental health scores did not differ between participants with and without NASH or by degree of fibrosis. Conclusion: Adults with NAFLD have a significant decrement in QOL. Treatment of NAFLD should incorporate strategies to improve QOL, especially physical health. (HEPATOLOGY 2009.)

Abstract

Sex and sex hormones can affect responses of patients with nonalcoholic fatty liver disease (NAFLD) to metabolic stress and development of hepatocyte injury and inflammation. We collected data from 3 large US studies of patients with NAFLD (between October 2004 and June 2013) to assess the association between histologic severity and sex, menopause status, synthetic hormone use, and menstrual abnormalities in 1112 patients with a histologic diagnosis of NAFLD. We performed logistic or ordinal logistic regression models, adjusting for covariates relevant to an increase of hepatic metabolic stress. We found that pre-menopausal women were at an increased risk of lobular inflammation, hepatocyte ballooning, and Mallory-Denk bodies than men and also at an increased risk of lobular inflammation and Mallory-Denk bodies than post-menopausal women (P

Abstract

Aims: Fish and v-3 fatty acids are reported to be beneficial in pediatric nonalcoholic fatty liver disease (NAFLD), but no studies have assessed their relation to histological severity. The objectives of this study were to evaluate the dietary intake of fish and v-3 fatty acids in children with biopsy-proven NAFLD, and examine their association with serological and histological indicators of disease. Methods: This was a cross-sectional analysis of 223 children (6–18 years) who participated in the Treatment of Nonalcoholic Fatty Liver Disease in Children trial or the NAFLD Database study conducted by the Nonalcoholic Steatohepatitis Clinical Research Network. The distribution of fish and v-3 fatty acid intake was determined from responses to the Block Brief 2000 Food Frequency Questionnaire, and analyzed for associations with serum alanine aminotransferase, histological features of fatty liver disease, and diagnosis of steatohepatitis after adjusting for demographic, anthropometric, and dietary variables. Results: The minority of subjects consumed the recommended 8 ounces of fish per week (22/223 [10%]) and 200 mg of long-chain v-3 fatty acids per day (12/223 [5%]). Lack of fish and long-chain v-3 fatty acid intake was associated with greater portal (P ¼ 0.03 and P ¼ 0.10, respectively) and lobular inflammation (P ¼ 0.09 and P ¼ 0.004, respectively) after controlling for potential confounders. Conclusions: Fish and v-3 fatty acid intake was insufficient in children with NAFLD, which may increase susceptibility to hepatic inflammation. Patients with pediatric NAFLD should be encouraged to consume the recommended amount of fish per week.

Abstract

Adult nonalcoholic fatty liver disease (NAFLD) is characterized by absent or mild portal chronic inflammation (CI); in children, portal CI may be predominant. This study correlated clinical features with portal CI. Centrally-graded biopsies and temporally-related clinical parameters from 728 adults and 205 children. From the Nonalcoholic Steatohepatitis Clinical Research Network (NASH CRN) were evaluated. Mild, more than mild and no portal CI were found in 60%, 23% and 16% of adult biopsies and 76%, 14% and 10% of pediatric biopsies. Autoantibodies, and elevated alanine aminotransferase were not associated with portal CI. Clinical features associated with “more than mild” in adults were older age (P < 0.0001), female gender (P = 0.001), higher body mass index (P < 0.0001), elevated insulin levels (P = 0.001), higher homeostasis model assessment of insulin resistance score (HOMA-IR) (P < 0.0001), and medications used for NAFLD (P = 0.0004), diabetes (P < 0.0001), and hypertension (P < 0.0001). “More than mild” in the pediatric biopsies correlated with younger age (P = 0.01), but not with body mass index, insulin or HOMA-IR. In both groups, lobular and portal inflammation scores had no association, but there was an association with definite steatohepatitis (P < 0.0001). Features associated in the adult biopsies with “more than mild” were steatosis amount (P = 0.01) and location (P < 0.0001), ballooning (P < 0.0001), and advanced fibrosis (P < 0.0001). In the pediatric biopsies, “more than mild” was associated with steatosis location (P = 0.0008) and fibrosis score (P < 0.0001), specifically, the portal/periportal fibrosis or greater fibrosis) (P < 0.01). Conclusion: Increased portal CI is associated with many clinical and pathologic features of progressive NAFLD in both adults and children, but not with ALT, autoantibodies, or lobular inflammation. More than mild portal CI in liver biopsies of untreated NAFLD may be considered a marker of advanced disease. (HEPATOLOGY 2009.)
