Symptomatic and pathophysiologic predictors of hepatitis C virus progression in pediatric patients.

ABSTRACT: BACKGROUND:The slow progression of hepatitis C virus (HCV) infection could ultimately negatively impact pediatric patients during their lifespan. This study describes the symptomatic and pathophysiologic presentation of HCV infection in a cohort of pediatric outpatients. METHODS:HCV-positive patients were identified by diagnosis codes from outpatient visits. Demographic and pathophysiologic indicators (comorbidities, reported symptoms, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV viral load, genotype, and liver biopsy results) were collected and analyzed. RESULTS:We reviewed 62 patients with HCV infection who were from 3 months and 19 years of age (M +/- SD, 12.5 +/- 5.8 years). Sixty percent presented with clinical symptoms of fatigue, joint-abdominal pain, bruising/bleeding, or other non-specific symptoms. On liver biopsy (n = 35) 80% had evidence of inflammation, 57% had fibrosis, and 9% had steatosis. All patients with steatosis or cirrhosis reported symptoms. Males were significantly more likely than women to be symptomatic (58.3% vs. 41.7%, P = 0.04). Patients with symptoms were significantly older (M = 13.5 +/- 5.2 vs. 8.9 +/- 5.5 years, P = 0.003). There was a significant inverse relationship between viral load and symptoms (chi = 4.75, P = 0.03). Patients with low viral load (<2 million copies) were 5 times more likely to have symptoms than those with high viral loads (P = 0.03). Significance was also noted between HCV genotype and ALT levels (chi = 3.72, P = 0.05). There were no significant relationships between symptom status and race, comorbidities, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV genotype, or liver histology. CONCLUSION:Pediatric patients with HCV can have significant symptoms and physiologic liver changes related to HCV.

Project description:Background and purposeWhile prior studies identified risk factors for recurrent stroke in patients with symptomatic intracranial atherosclerotic disease, few have assessed risk factors for early infarct recurrence.MethodsWe performed a post hoc analysis of the MYRIAD study (Mechanisms of Early Recurrence in Intracranial Atherosclerotic Disease) of intracranial atherosclerotic disease patients with recent (<21 days) stroke/transient ischemic attack, 50% to 99% stenosis and who underwent 6- to 8-week magnetic resonance imaging (MRI) per protocol. Infarct recurrence was defined as new infarcts in the territory of the symptomatic artery on brain MRI at 6 to 8 weeks compared to index brain MRI. Qualifying events and clinical and imaging outcomes were centrally ascertained by 2 independent reviewers. We assessed the association between baseline clinical and imaging variables and recurrent infarct in bivariate models and multivariable logistic regression to identify independent predictors of infarct recurrence.ResultsOf 105 enrolled patients in MYRIAD, 89 (84.8%) were included in this analysis (mean age, 64±12 years, 54 [60.7%] were male, and 53 [59.6%] were White). The median time from qualifying event to MRI was 51+16 days, on which 22 (24.7%) patients had new or recurrent infarcts. Younger age (57.7 versus 66.0 years; P<0.01), diabetes (32.6% versus 14.6%, P=0.05), index stroke (31.3% versus 4.6%, P=0.01), anterior circulation location of stenosis (29.7% versus 12.0%, P=0.08), number of diffusion-weighted imaging lesions (>1: 40.0%, 1: 26.9% versus 0: 4.4%, P<0.01), and borderzone infarct pattern (63.6% versus 25.0%, P=0.01) on baseline MRI were associated with new or recurrent infarcts. Age (adjusted odds ratio, 0.93 [95% CI, 0.89-0.98], P<0.01) and number of diffusion-weighted imaging lesions (adjusted odds ratio, 3.24 [95% CI, 1.36-7.71], P<0.01) were independently associated with recurrent infarct adjusting for hypertension, diabetes, and stenosis location (anterior versus posterior circulation).ConclusionsAn index multi-infarct pattern is associated with early recurrent infarcts, a finding that might be explained by plaque instability and artery-to-artery embolism. Further investigation of plaque vulnerability in intracranial atherosclerotic disease is needed. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT02121028.
