Background: The etiology of herniated intervertebral disc (HIVD) disease in children and adolescents is multifactorial and not merely related to disc degeneration. Therefore, in the present study, we investigated the relationship between young asthma patients and the risk of early HIVD disease in a population under 30 years of age.Methods: Data from the National Health Insurance Research Database (NHIRD) of Taiwan were used to conduct a retrospective longitudinal cohort study. The study cohort comprised 23,470 patients with asthma (asthma group) and 23,470 patients without asthma (non-asthma group), who were selected through frequency matching on the basis of sex, age, and the index year. The study patients were followed until HIVD disease occurrence, withdrawal from the National Health Insurance program, or 31 December 2013. Cox proportional hazards regression analysis was conducted to assess the risk of HIVD disease in the asthma group after adjustment for sex, age, and comorbidities.Results: After adjustment for sex, age, and comorbidities, the asthma group had a 1.69-fold (95% confidence interval [CI] = 1.29-2.23) higher risk of HIVD disease than did the non-asthma group. In addition, the asthma group had a higher risk of cervical and lumbar HIVD diseases than did the non-asthma group (adjusted hazard ratio [HR] = 2.38; 95% CI = 1.25-4.57 and adjusted HR = 1.56; 95% CI = 1.15-2.12, respectively).Conclusions: Young patients with asthma are at a significantly higher risk of early cervical or lumbar HIVD disease.

In Oriental countries, combinations of Chinese herbal products (CHPs) are often utilized as therapeutic agents for chronic obstructive pulmonary disease (COPD). The effects of CHPs on COPD have been previously reported. This study aimed to analyze the frequency of prescription and usage of CHPs in patients with COPD in Taiwan. In this nationwide population-based cross-sectional study, 19,142 patients from a random sample of one million individuals in the Longitudinal Health Insurance Database 2000 (LHID 2000) of the National Health Insurance Research Database (NHIRD) were enrolled from 2000 to 2011. The multiple logistic regression method was used to evaluate the adjusted odds ratios for the utilization of CHPs. For patients with COPD, there was an average of 6.31 CHPs in a single prescription. The most frequently prescribed CHP for COPD was Xiao-Qing-Long-Tang (XQLT) (2.6%), and the most commonly used combination of two formula CHPs was XQLT with Ma-Xing-Gan-Shi-Tang (MXGST) (1.28%). The most commonly used single CHP for COPD was Bulbus Fritillariae (3.65%), and the most commonly used combination of two single CHPs was Bulbus Fritillariae with Puerariae Lobatae (1.09%). These results provide information regarding personalized therapies and may promote further clinical experiments and pharmacologic research on the use of CHPs for the management of COPD. Furthermore, we found that TCM usage was more prevalent among men, younger, manual workers, residents of Northern Taiwan, and patients with chronic bronchitis and asthma. This information on the distribution of TCM usage around the country is valuable to public health policymakers and clinicians. [ABSTRACT FROM AUTHOR]
