Health-related Quality of Life in Pediatric Patients With Chronic Hepatitis B Living in the United States and Canada

OBJECTIVES: The aim of the study was to determine whether selected sociodemographic and hepatitis B virus (HBV)-specific clinical factors are associated with health-related quality of life (HRQoL) among pediatric patients chronically infected with HBV. METHODS: Children with chronic HBV enrolled in the Hepatitis B Research Network completed the Child Health Questionnaire at study entry. Caregivers of children 5 to <10 years completed the parent-reported form (CHQ-Parent Report Form); youth 10 to <18 years completed the child-reported CHQ-Child Report Form. We examined univariable associations of the Child Health Questionnaire scores with selected independent variables: sex, adoption status, maternal education, alanine aminotransferase (U/L), aspartate aminotransferase-to-platelet ratio index, and HBV-specific symptom count. RESULTS: A total of 244 participants (83 young children 5-<10 years, 161 youth 10-<18 years) were included, all HBV treatment-naïve. Among young children, increased alanine aminotransferase level was negatively associated with CHQ-Parent Report Form psychosocial summary t score (r = -0.28, P = 0.01). No other subscale comparisons for young children were statistically significant. Among youth, adoption was associated with better physical functioning and general health (P < 0.01). Higher maternal education was associated with better role/functioning-physical and -emotional scores (P < 0.05). Maternal education and adoption status were linked with adoption associated with higher maternal education. Increased symptom count in youth was associated with worse HRQoL in subscales measuring bodily pain, behavior, mental health, and self-esteem (P < 0.01). CONCLUSIONS: Although overall HRQoL is preserved in children with chronic HBV, some sociodemographic and HBV-related clinical factors were associated with impaired HRQoL in our pediatric patients at baseline. Measurement of HRQoL can focus resources on education and psychosocial support in children and families most in need

Characteristics of Adults in the Hepatitis B Research Network in North America Reflect Their Country of Origin and Hepatitis B Virus Genotype

Chronic hepatitis B virus (HBV) infection is an important cause of cirrhosis and hepatocellular carcinoma worldwide; populations that migrate to the US and Canada might be disproportionately affected. The Hepatitis B Research Network (HBRN) is a cooperative network of investigators from the United States and Canada, created to facilitate clinical, therapeutic, and translational research in adults and children with hepatitis B. We describe the structure of the network and baseline characteristics of adults with hepatitis B enrolled in the network

Prevalence and associated risk factors of sleep-disordered breathing symptoms in young and middle-aged Pakistani employed adults

Purpose: The objective of this study was to evaluate the prevalence of self-reported sleep-disordered breathing (SDB symptoms and its associated risk factors in Pakistani employed adults. Method: Full-time employees (n = 3470) of a medical university were evaluated. Self-administered questionnaire elicited information about demographic data, symptoms of SDB, smoking and alcohol use, presence of nasal congestion, family history of snoring, and included the Epworth Sleepiness Scale. Prevalence of self-reported snoring and of combined SDB symptoms (snoring plus at least one other SDB symptom) was evaluated. Regression analyses were used to assess risk factors associated with self-reported snoring and combined SDB symptoms. Results: Among the 2,497 (72%) responders, prevalence of self-reported snoring was 32%, and combined SDB symptoms 25%. A higher prevalence of snoring and combined SDB symptoms in male gender diminished with age. In univariate analysis, the odds of snoring was higher with age a parts per thousand yen35 yrs (odds ratio (OR) 2.6, confidence interval (CI) 2.2-3.2), body mass index a parts per thousand yen23 (OR 2.6, CI 2.2-3.1), and collar size above 40 cm (OR 2.7, CI 2.3-3.3). Self-reported nasal blockage (OR 1.9, CI 1.6-2.2) and family history of snoring (OR 2.9, 2.5-3.5) were other risk factors. In logistic regression analysis, significant risk factors for SDB symptoms were age, body mass index, collar size, nasal blockage, and family history of snoring. Male gender, smoking and alcohol were not significant risk factors for SDB symptoms. Conclusion: The prevalence of SDB symptoms in Pakistani employed adults was comparable to Western populations. However, male gender and smoking were not significant risk factors for SDB symptoms

Association of self-reported nasal blockage with sleep-disordered breathing and excessive daytime sleepiness in Pakistani employed adults

Purpose: To assess prevalence of self-reported nasal congestion and its association with sleep-disordered breathing (SDB) and excessive daytime sleepiness (EDS) in Pakistani adults employed at a medical university. Methods: All full-time employees of a medical university (n=3,470) were delivered a questionnaire that elicited demographic data, symptoms of nasal blockage and SDB and Epworth Sleepiness Scale score. Overnight pulse oximetry was performed on self-reported snorers and a random sample of non-snorers. Supervised polysomnography was performed on subjects with oxygen desaturation index \u3e5/h. Logistic regression analysis was used to assess the association of nasal blockage with SDB and EDS. Results: Of 2,497 (72%) responders, 45.2% reported nasal congestion. Self-reported nasal blockage was significantly associated with an increased risk of SDB symptoms: snoring (odds ratio [OR] 1.9), witnessed apnoea (OR, 2.2) and unrefreshing sleep (OR, 1.7). Those with nasal blockage had higher Epworth Sleepiness Scale score (5.5 +/- 3.6 vs. 3.9 +/- 3.3, pConclusion: Self-reported nasal blockage is a common symptom in employed Pakistani adults. Self-reported nasal blockage is significantly associated with symptoms of SDB and EDS but not with respiratory variables on overnight sleep monitoring
