RESUMO

Objective: This study aimed to evaluate the effects of TX-001HR (17ß-estradiol [E2] and progesterone [P4] in a single oral capsule) on cardiometabolic markers and outcomes. Methods: Four E2/P4 doses (1 mg/100 mg, 0.5 mg/100 mg, 0.5 mg/50 mg, 0.25 mg/50 mg) were compared with placebo in menopausal women with vasomotor symptoms (VMS) and a uterus in the phase 3 REPLENISH (ClinicalTrials.gov, NCT01942668) trial. Changes in lipid and coagulation parameters and blood glucose from baseline at 6, 9, and 12 months as well as cardiovascular events are summarized. Results: A total of 1835 participants took ≥1 capsule of daily E2/P4; 1684 received E2/P4 and 151 received placebo. No clinically significant changes in lipid parameters, coagulation factors, or glucose were observed between treatment groups. Minimal increases of potential clinical importance were observed in total cholesterol, triglycerides, and glucose at month 12 with E2/P4 (1-4%, 6-11%, and 1%, respectively) and placebo (3%, 7%, and 2%, respectively). One episode of deep venous thrombosis and three cases of cardiovascular disease were observed, similar to expected rates of these events in the general population. Conclusions: In the REPLENISH trial, postmenopausal women with VMS treated with E2/P4 had no clinically meaningful effects on lipids, glucose, or coagulation parameters compared with placebo.

RESUMO

Melkersson-Rosenthal syndrome is a rare granulomatous neuro-mucocutaneous systemic disease that is characterized by relapsing peripheral facial paralysis, orofacial edema and fissured tongue. The disease etiology is still not well known, but it has been hypothesized that a possible role is played by various causal agents such as infectious diseases, genetic causes, allergic conditions, benign lymphogranulomatosis, various associations with other pathological conditions, particularly with immune-mediated diseases and food contact allergies. In this report we describe the case of a woman, 42 years old, with psoriatic arthritis who developed neurological episodes related to MRS after treatment with anti-TNF therapy. This finding further supports the hypothesis that TNF-alpha blockade, and particularly the use of the TNF-alpha receptor, could trigger the development of granulomatous lesions in predisposed patients. The case we report further sustains the importance for the clinician to take into account this potential adverse event in patients receiving anti-TNF-alpha therapies.

RESUMO

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the leading liver disorder among U.S. children and is most prevalent among Hispanic children with obesity. Previous research has shown that reducing the consumption of free sugars (added sugars + naturally occurring sugars in fruit juice) can reverse liver steatosis in adolescents with NAFLD. This study aims to determine if a low-free sugar diet (LFSD) can prevent liver fat accumulation and NAFLD in high-risk children. METHODS: In this randomized controlled trial, we will enroll 140 Hispanic children aged 6 to 9 years who are ≥50th percentile BMI and without a previous diagnosis of NAFLD. Participants will be randomly assigned to either an experimental (LFSD) or a control (usual diet + educational materials) group. The one-year intervention includes removal of foods high in free sugars from the home at baseline, provision of LFSD household groceries for the entire family (weeks 1-4, 12, 24, and 36), dietitian-guided family grocery shopping sessions (weeks 12, 24, and 36), and ongoing education and motivational interviewing to promote LFSD. Both groups complete assessment measures at baseline, 6, 12, 18, and 24 months. Primary study outcomes are percent hepatic fat at 12 months and incidence of clinically significant hepatic steatosis (>5%) + elevated liver enzymes at 24 months. Secondary outcomes include metabolic markers potentially mediating or moderating NAFLD pathogenesis. DISCUSSION: This protocol describes the rationale, eligibility criteria, recruitment strategies, analysis plan as well as a novel dietary intervention design. Study results will inform future dietary guidelines for pediatric NAFLD prevention. TRIAL REGISTRATION: ClinicalTrials.gov, NCT05292352.

RESUMO

OBJECTIVES: According to most existing models, a computer is usually needed for predicting stroke outcome. Our purpose was to construct a simple and reliable prognostic scale not requiring the use of a calculating machine. MATERIALS AND METHODS: The scale [the Bologna Outcome Algorithm for Stroke (BOAS)] was obtained in 221 patients with ischemic stroke not undergoing thrombolysis and was then validated in a test group of 100 different patients. Outcome was assessed at 9 months as the number of dependent or dead patients (modified Rankin scale - mRS > 2). RESULTS: By a preliminary systematic univariate analysis, 25 of 415 baseline variables were found to be associated with a mRS > 2 independently of stroke severity and age. Subsequent multivariable analyses led to a final model based on five dichotomous risk factors (RF): National Institutes of Health Stroke Scale score ≥10, age ≥78, need of urinary catheter, oxygen administration, and persistence of upper limb paralysis at discharge from stroke unit. The patients with two or more RF (53%) had a mRS > 2 in 91% of cases and were dead in 42% of cases. With 0-1 RF, the two percentages were 24% and 2%, respectively (overall accuracy of prediction 83.9%, area under ROC curve [AUC] 0.891). In the test group, the accuracy was 79.0% and the AUC was 0.839. CONCLUSIONS: The need of urinary catheter, oxygen administration, and persistence of upper limb paralysis, together with stroke severity and advanced age, allow a simple and accurate prediction of dependency or death after ischemic stroke.

RESUMO

BACKGROUND: Thromboembolism is a complication of acute lymphoblastic leukemia therapy in children. The majority of thromboembolic events are cerebral thromboses and deep venous thromboses; many asymptomatic deep venous thromboses are detected in children with acute lymphoblastic leukemia by instrumental screening. The aim of this study was to assess the incidence of asymptomatic cerebral thromboembolic events in children with acute lymphoblastic leukemia (ALL) screened by magnetic resonance imaging and magnetic resonance venography. METHODS: 46 children with acute lymphoblastic leukemia, during the induction phase of the AIEOP ALL 2000 protocol, were stratified into 2 groups. In group "A" cerebral thromboembolic events were suspected following the appearance of suggestive signs and symptoms and confirmed by cerebral magnetic resonance imaging and magnetic resonance venography; in group "B" children underwent a screening by cerebral magnetic resonance imaging and magnetic resonance venography, at set times, in absence of symptoms. RESULTS: We observed one cerebral thromboembolic event in both groups; we found no differences between early detecting asymptomatic cerebral thromboembolic events among monitored and not monitored patients. CONCLUSIONS: Our study does not seem to suggest a screening for asymptomatic cerebral thromboembolic events in children with ALL during the induction phase.

RESUMO

The hypothalamic-pituitary-ovarian (HPO) axis goes through a series of complicated, but well coordinated changes as a women enters the menopausal transition. The reproductive consequences of these changes are obvious, but there are also a number of general health consequences as well. As our understanding of the complex inter-workings of the HPO axis evolves, we will be better able to predict menopausal events and create strategies and treatments to optimize women's health as the progress through the menopausal transition.

RESUMO

AIMS/HYPOTHESIS: A high but normal fasting plasma glucose level in adults is a risk factor for future development of type 2 diabetes mellitus and cardiovascular disease. We investigated whether normal fasting plasma glucose levels (<5.60 mmol/l) are associated with decreases in insulin sensitivity and beta cell function, as well as an adverse cardiovascular profile in obese youth. METHODS: We performed a cross-sectional analysis in a multiethnic sample of 1,020 obese youth (614 girls and 406 boys; mean age 12.9 years [CI 95% 12.7-13.1], BMI z score 2.34 [CI 95% 2.31-2.38]) with normal fasting plasma glucose. All participants had a standard OGTT, with calculation of indices of insulin sensitivity and beta cell function. For the analysis, prepubertal and pubertal participants were stratified into quartiles of normal fasting plasma glucose. RESULTS: We observed a significant increase in fasting insulin and AUC 2 h glucose across quartiles. Pronounced changes were observed in insulin sensitivity and secretion, particularly in the pubertal group. Moreover, the odds of presenting with impaired glucose tolerance increased by 4.5% with each 0.06 mmol/l increase in fasting plasma glucose. No significant differences in cardiovascular indices were seen across quartiles. CONCLUSIONS/INTERPRETATION: These data suggest that in obese youth, independent of age, BMI z score, sex, family history and ethnicity, insulin sensitivity and secretion decline when moving from low to high normal fasting plasma glucose. The simple measure of fasting plasma glucose could assist clinicians in identifying children for targeted diabetes screening and subsequent lifestyle management.

RESUMO

Iron deficiency has been linked to obesity. Hepcidin is the main regulator of iron homeostasis and is higher in obese children compared to controls. To gain insight into the link between obesity and hepcidin, we performed an intervention study in 15 obese children. These children were subjected to a 6-month weight loss program and underwent physical examination and iron status and absorption as well as hepcidin, interleukin-6 and leptin serum levels evaluation at baseline and after the weight loss program. After the program all children reduced their body mass index standard deviation score (BMI SDS) of at least 0.5. We observed a significant decrease in hepcidin (P=0.003) and leptin levels (P=0.005), and a significant increase in iron absorption (P=0.02). A direct correlation between the measure of hepcidin and leptin reduction was observed and this correlation appeared significant (r²=0.33, P=0.003) when adjusted for interleukin-6 and BMI SDS variations. In conclusion, we have shown that, in obese children, BMI reduction is associated with hepcidin reduction, potentially improving iron status and absorption. Implications of these findings could be considered in the management of obese children with poor iron status.

RESUMO

METHOD: To test the hypothesis that psychosocial symptomatology differs by country of origin and acculturation among Hispanic women, we examined 419 women, aged 42-52 years at baseline, enrolled in the New Jersey site of the Study of Women's Health Across the Nation (SWAN). Women were categorized into six groups: Central (CA, n = 29) or South American (SA, n = 106), Puerto Rican (PR, n = 56), Dominican (D, n = 42), Cuban (Cu, n = 44) and non-Hispanic Caucasian (NHC, n = 142). Acculturation, depressive symptoms, hostility/cynicism, mistreatment/discrimination, sleep quality, social support, and perceived stress were assessed at baseline. Physical functioning, trait anxiety and anger were assessed at the fourth annual follow-up. Comparisons between Hispanic and non-Hispanic Caucasians used χ², t test or non-parametric alternatives; ANOVA or Kruskal-Wallis testing examined differences among the five Hispanic sub-groups. Multivariable regression models used PR women as the reference group. RESULTS: Hispanic women were overall less educated, less acculturated (p < 0.001 for both) and reported more depressive symptoms, cynicism, perceived stress, and less mistreatment/discrimination than NHCs. Along with D women, PR women reported worse sleep than Cu women (p < 0.01) and more trait anxiety than SA and Cu women (p < 0.01). Yet, PR women were most acculturated (21.4% highly acculturated vs. CA (0.0%), D (4.8%), SA (4.8%) and Cu (2.3%) women; p < 0.001). In regression models, PR women reported depressive symptoms more frequently than D, Cu, or SA women, and reported trait anxiety more frequently than Cu or SA women. Greater acculturation was associated with more favorable psychosocial status, but PR ethnicity was negatively related to psychosocial status. CONCLUSION: Psychosocial symptomatology among Hispanic women differs by country of origin and the relatively adverse profile of Puerto Rican women is not explained by acculturation.

RESUMO

INTRODUCTION: Since the designation of people as Hispanic involves the amalgamation of a number of different cultures and languages, we sought to test the hypothesis that menopausal symptoms would differ among Hispanic women, based upon country of origin and degree of acculturation. METHODS: A total of 419 women, aged 42-52 years at baseline, were categorized as: Central American (CA, n = 29) or South American (SA, n = 106), Puerto Rican (PR, n = 56), Dominican (D, n = 42), Cuban (Cu, n = 44) and non-Hispanic Caucasian (n = 142). We assessed vasomotor symptoms, vaginal dryness and trouble in sleeping. Hispanics and non-Hispanic Caucasians were compared using the chi(2) test, t test or non-parametric alternatives; ANOVA or Kruskal-Wallis testing examined differences among the five Hispanic sub-groups. Multivariable regression models used PR women as the reference group. RESULTS: Hispanic women were overall less educated, less acculturated (p < 0.001 for both) than non-Hispanic Caucasians and more of them reported vasomotor symptoms (34.1-72.4% vs. 38.3% among non-Hispanic Caucasians; p = 0.0293) and vaginal dryness (17.9-58.6% vs. 21.1% among non-Hispanic Caucasians, p = 0.0287). Among Hispanics, more CA women reported vasomotor symptoms than D, Cu, SA, or PR women (72.4% vs. 45.2%, 34.1%, 50.9%, and 51.8%, respectively). More CA (58.6%) and D women (38.1%) reported vaginal dryness than PR (17.9%), Cu (25.0%) and SA (31.4%) women. More PR and D women reported trouble in sleeping (66.1 and 64.3%, respectively) compared to CA (51.7%), Cu (36.4%), and SA (45.3%) women. CONCLUSION: Symptoms associated with menopause among Hispanic women differed by country of origin but not acculturation. Central American women appear to be at greatest risk for both vasomotor symptoms and vaginal dryness.

RESUMO

OBJECTIVE: Scanty data are available about the thyroid function in childhood acute lymphoblastic leukemia (ALL) off-therapy patients treated only with chemotherapy. We aimed to assess the prevalence of thyroid autoimmunity and thyroid dysfunction in such patients. DESIGN: Case-control cross-sectional study. METHODS: Eighty-four patients diagnosed with ALL and treated only with chemotherapy. Mean age at diagnosis 5.9+/-3.6 yr, at recruitment 12.1+/-4.3 yr. The treatment had been stopped 4.3+/-3.2 yr before recruitment. A control group of 60 subjects was recruited. Free T4, TSH, anti-thyroperoxidase, and anti-thyroglobulin antibodies were measured. RESULTS: Anti-thyroglobulin and anti-thyroperoxidase antibodies were negative in all patients. TSH was increased in 7 patients (8.3%) and 3 controls (5.0%). Free T4 was within the normal limits in all patients and controls.Mean TSH and free T4 levels did not statistically differ between controls and ALL offtherapy patients. TSH was negatively correlated with the age at the diagnosis (p=0.01) and the age at the end of therapy (p=0.008). Anti-thyroglobulin and/or anti-thyroperoxidase antibodies were detected in 3 controls (5%; vs study group: p=0.038), 1 of them with increased TSH. CONCLUSIONS: Some patients present hyperthyrotropinemia, without anti-thyroid antibodies, with a prevalence comparable to the control group. The thyroid gland seems more prone to be damaged by chemotherapy at a younger age. We think that a thyroid follow- up in ALL off-therapy patients may be advisable and should be differentiated on the basis of the age at the end of treatment, with more frequent tests for younger patients.

RESUMO

A nosocomial outbreak of 2009 pandemic influenza A(H1N1), with eight confirmed cases, occurred in a paediatric oncology ward in Italy, in October/November 2009. The fact that one case was infected despite being isolated and without contact to a symptomatic patient, hints towards potential transmission through a health care worker (HCW) and underlines the importance of vaccination of HCW who are involved in the care of critically ill patients.

RESUMO

Retinol binding protein 4 (RBP4) is an adipokine involved in the pathogenesis of insulin resistance in obese adults and children. Since insulin resistance occurs during puberty, independently of adiposity, a role for RBP4 in the onset of this phenomenon may be hypothesized. In order to verify our hypothesis, we studied 90 subjects (45 obese and 45 lean controls). A complete physical examination was assessed, the z-score body mass index (BMI) was calculated, fat mass was assessed by bioelectric impedance analysis, and pubertal stage was assessed according to Tanner. Serum insulin and serum RBP4 levels were assayed. Obese and lean children differed for z-score BMI, fat mass, homeostasis model assessment of insulin resistance (HOMA-IR) and RBP4 levels. z-score BMI and HOMA-IR showed a direct correlation with RBP4 in the total population. When the subjects were divided in lean and obese, this correlation was evident only in obese (r2: 0.2; p=0.009 and r2: 0.2; p=0.01), but not in lean subjects (r2: 0.09; p=0.1 and r2: 0.03; p=0.4). Both in obese and lean HOMA-IR values were higher in pubertal subjects than in pre-pubertal (p<0.001), while serum RBP4 levels were similar in pubertal and in pre-pubertal subjects (>0.1). We conclude that RBP4 is correlated with adiposity and insulin resistance in obese children, but it is not involved in the insulin resistance occurring during puberty.

RESUMO

Aim of our study is to verify the association between the genetic predisposition to hyperinsulinism due to the presence of the insulin gene (INS) I/I genotype and the development of sleep-related breathing disorders (SRBD) in obese children and adolescents. Two hundred and fifty-six obese children and adolescents (125 girls) have been investigated. As initial screening all subjects' mothers filled out the Sleep Disturbances Scale for Children (SDSC). The Sleep-Disordered Breathing (SDB) scale has been taken into account. Successively, a subgroup of 34 patients belonging to the first (14 children) and the last (20 children) SDB score quintiles underwent an overnight polysomnography and the apnea-hypopnea index (AHI) was evaluated. All subjects were genotyped for the INS VNTR and fasting insulin levels were evaluated. The population was divided into two groups according to the genotype: the first group was comprehensive of patients homozygotes for class I allele and the second group was composed by class III allele heterozygotes and homozygotes patients. Subjects I/I showed statistically signifIcant higher insulin levels (p<0.001) and SDB scores (p<0.001). Moreover, in the subgroup of patients investigated with polysomnography, class I homozygous subjects showed higher AHI compared to those patients carrying class III allele (p<0.001). Our data support the hypothesis that INS VNTR is associated with the development of SDB among obese children and adolescents.

RESUMO

CONTEXT: Reproductive hormones are incompletely characterized during the menopause transition (MT). HYPOTHESIS: Increased anovulation and decreased progesterone accompany progress through the MT. DESIGN: The Daily Hormone Study (DHS) of the Study of Women's Health Across the Nation (SWAN) included 848 women aged 43-53 yr at baseline who collected daily urine for one cycle or up to 50 d annually for 3 yr. MAIN OUTCOME MEASURES: LH, FSH, estrone conjugates, and pregnanediol glucuronide levels were assessed. Cycles were classified by presumed luteal (ovulatory) status and bleeding. Hormones were related to time in study, age, menopausal status, and selected variables. RESULTS: Ovulatory-appearing cycles declined from 80.9% at baseline to 64.7% by the third assessment (H3). Cycles presumed anovulatory and not ending with bleeding by 50 d (anovulatory/nonbleeding) increased from 8.4 to 24% by H3 and were associated with progress to early perimenopause [odds ratio (OR) = 2.66; confidence interval (CI) = 1.17-6.04] or late perimenopause (OR = 56.21; CI = 18.79-168.12; P < 0.0001), African-American ethnicity (OR = 1.91; CI = 1.06-3.43), and less than high school education (OR = 3.51; CI = 1.62-7.62). Anovulatory cycles ending with bleeding remained at about 10% from baseline to H3; compared with ovulatory cycles, they were associated with obesity (OR = 4.68; CI = 1.33-16.52) and more than high school education (OR = 2.12; CI = 1.22-3.69; P = 0.02). Serum estradiol in both the highest and lowest categories was associated with anovulatory/nonbleeding collections. Pregnanediol glucuronide decreased 6.6% for each year on study. Insulin sensitivity measures did not relate strongly to menstrual cycle hormones. CONCLUSIONS: Anovulation without bleeding represents progression of the MT. A small but detectable decrease in luteal progesterone excretion occurs as women progress through the MT.

RESUMO

Hypogonadotropic hypogonadism (HH) is a clinical syndrome occurring in both sexes which has long puzzled clinicians due to the apparent paradox of nonfunctioning gonads in the face of normal or only slightly lowered levels of circulating gonadotropins. Using frequent sampling of gonadotropin levels as an index of hypothalamic GnRH secretion, we have examined the hypothesis that this group of disorders represents a spectrum of abnormal patterns of the pulsatile release of endogenous GnRH. After a broad, normative data base was established in both men and women for purposes of comparison, it appears that quantifiable abnormalities of GnRH secretion are discernible in both males and females with HH. These abnormalities include a total absence of GnRH secretion, defects of the amplitude and frequency of its secretion, and altered bioactivity of the gonadotropins released. In addition, physiological regimens of hypothalamic replacement therapy with exogenous GnRH, which are fashioned to mimic the normal frequency of endogenous GnRH secretion, result in complete normalization of reproductive function and fertility in hypogonadotropic subjects of both sexes. Thus, the heterogeneous nature of HH, as well as its favorable clinical and biochemical responses to GnRH, suggest that the basic defect in this family of disorders involves a partial or complete inability to synthesize and/or release GnRH from the hypothalamus in a manner compatible with physiological reproductive function. Conversely, these findings imply that maintenance of a physiological amplitude and frequency of endogenous GnRH secretion appear to be essential for normal reproductive function.

RESUMO

BACKGROUND: The purpose of this study was to provide practical, evidence-based guidelines for evaluating and treating common menopausal symptoms following breast cancer. METHODS: Literature review of the causes, assessment and management of menopausal symptoms in breast cancer patients. RESULTS: A number of nonhormonal treatments are effective in treating hot flashes. Whether pharmacological treatment is given will depend on the severity of symptoms and on patient wishes. For severe and frequent hot flashes, the best data support the use of venlafaxine, paroxetine and gabapentin in women with breast cancer. Side-effects are relatively common with all these agents. For vaginal dryness, topical estrogen treatment is the most effective but the safety of estrogens following breast cancer is not established. There are limited data on effective treatments for sexual dysfunction during menopause. CONCLUSION: Menopausal symptoms after breast cancer should be evaluated and managed as warranted using a systematic approach and may benefit from multidisciplinary input.

RESUMO

The natural history of impaired glucose tolerance (IGT) and Type 2 diabetes among obese children is not clear. Although the cut-off for impaired fasting glucose (IFG) has recently been changed from 110 (6.1 mmol/l) to 100 mg/dl (5.6 mmol/l), it does not seem a reliable way to find all subjects with impaired glucose homeostasis. The aim of our study was to determine whether high-normal fasting glucose level could predict the occurrence of IGT and metabolic syndrome. Three hundred and twenty-three Italian obese children and adolescents were included in the study (176 females, mean age 11+/-2.9 yr; mean body mass index z-score: 3+/-0.6). Waist circumference, serum glucose, insulin, triglyceride, cholesterol HDL, blood pressure were evaluated and an oral glucose tolerance test (OGTT) was performed. The prevalence of IFG and IGT were respectively 1.5% (5 subjects) and 5% (18 patients); no diabetic patients were found. Metabolic syndrome was diagnosed in 20% of patients. Fasting glycemia values <100 mg/dl (5.6 mmol/l) have been divided in quintiles. Metabolic syndrome prevalence increased across quintiles, although not in a statistically significantly manner, but it could depend on the selected diagnostic criteria as no univocal definition exists for metabolic syndrome in youths. Interestingly high-normal fasting plasma glucose levels constitute an independent risk factor for IGT among obese children and adolescents; therefore, this very easy-to-use parameter may help to identify obese patients at increased risk of diabetes or at least could suggest in which subjects to perform an OGTT.

RESUMO

Scheuermann's disease (SD) or vertebral osteochondrosis is the most frequent cause of non postural kyphosis and one of more frequent cause of adolescent's dorsalgia. The criteria for the diagnosis are: more than 5 degrees of wedging of at least three adjacent vertebrae at the apex of the kyphosis; a toracic kyphosis of more than 45 of Cobb's degree; Schmorl's nodes and endplates irregularities. In addition to classic SD, there are radiological alterations that remain asymptomatic for a long time to reveal in adult age: in that case it speaks of adult Scheuermann's disease (ASD). We considered the diagnosis of patients came from April 2006 to April 2007 on Day Hospital in our Clinic. ASD was diagnosed, besides, in 10 of these patients. 7 patients had previous diagnosis such as: dorsal Spondiloarthrosis (4 subjects); Osteoporosis with vertebral fractures (3 subjects). All these diagnosis was not confirmed by us. In case of chronic dorsalgia of adult, ASD is rarely considered as differential diagnosis. Besides, the vertebral dorsalgia, even in absence of red flags as fever, asthenia,hypersedimetry, functional loss and aching spinal processes to tapping, could hide a serious scene that lead us to be careful in the differential diagnosis, because of similar radiological pictures of the MSA to other pathology as spondylodiscitis, primitive or metastasic spinal tumors, and brittleness vertebral fractures.

RESUMO

INTRODUCTION: Traffic-related air pollution causes fatty liver, inflammation and fibrosis in animal models, but there have been few studies in humans. OBJECTIVES: To test the hypothesis that traffic-related air pollution causes non-alcoholic fatty liver disease (NAFLD) and increased markers for non-alcoholic steatohepatitis (NASH); and that NAFLD increases liver susceptibility to increased NASH risk. METHODS: Data collected prospectively from 74 overweight or obese children were obtained from the Yale Pediatric Obesity Clinic. Traffic-related air pollution was characterized as vehicle traffic volume on major roads within a 1 km residential buffer, and as residential nitrogen dioxide (NO2 ) exposure. Outcomes were hepatic fat fraction (HFF) measured by magnetic resonance imaging, liver enzymes using standard assays and plasma cytokeratin-18 (CK-18) by immunosorbent assays. RESULTS: Significant non-linear relationships with air pollution and CK-18 were found. Plasma CK-18 at follow-up increased from approximately 150 U/L to almost 200 U/L as residential traffic volume increased from 220 000 vehicle-km to 330 000 vehicle-km, after adjustment for baseline CK-18, age and gender. Among patients with NAFLD at baseline, CK-18 increased from 140 U/L to 200 U/L (a 1.5 standard deviation increase in CK-18) as NO2 increased from 8 to 10 ppb. CONCLUSIONS: Traffic-related air pollution was associated with CK-18. Effects were larger in children with pre-existing NAFLD at study entry.
