Background: Inflammation may trigger migraine development through neurovascular reactions in the brain. Most of the migraine patients, particularly the younger ones, do not have any risk factors for this disease. Hence, we assessed whether chronic osteomyelitis (COM), a chronic inflammatory disease, increases the risk of migraine. Objective: We aim to evaluate the risk of migraine among female and middle-age COM patients with a large patient sample. Study Design: A retrospective cohort study was conducted in this study. Setting: The data used in this study were extracted from the Taiwan National Health Insurance (NHI) Research Database. Methods: A study group with 2,012 COM patients and 8,048 randomly chosen gender- and age-matched controls were chosen from the Taiwan NHI Research Database (NHIRD) from the start of 2000 to the end of 2009. The risk of migraine was estimated with Cox proportional regression model. Both COM and control groups were followed-up until the occurrence of migraine during the study period (2000–2011). Prevalent covariates, such as age, gender, hypertension, diabetes, hyperlipidemia, stroke, coronary artery disease, depression, anxiety, sleep disorder, bipolar disorder, and epilepsy, were included for further evaluation. The hazard ratio (HR) of migraine was measured with Cox proportional hazard regression model. The primary outcome was the overall migraine risk among COM patients, and the secondary outcome was the migraine risk among COM patients lacking the comorbidities. Additional outcomes included migraine risk among COM patients in different age and gender subgroups. Results: The overall migraine risk was increased in COM patients (adjusted hazard ratio [aHR] 1.74, 95% confidence interval [CI] 1.14–2.65). Even without any prevalent comorbidities, COM patients still exhibited an increased risk of migraine (aHR 2.05, 95% CI 1.06–3.97) than the controls did. Moreover, this risk was relatively higher in COM patients aged < 40 and 45–54 years (aHR 2.07, 95% CI 0.97–4.46 and aHR 2.11, 95% CI 0.97–4.57, respectively) than in their counterparts. Female COM patients had a relatively higher migraine risk (aHR 1.85, 95% CI 1.05–3.24) than male patients did (aHR 1.68, 95% CI 0.89–3.16). Limitations: The messages about personal behaviors were unavailable in the Taiwan NHIRD. Other neurovascular risk factors that might increase migraine cannot be excluded completely in this research. Conclusion: An association between COM and increased risk of migraine was shown in this study. The results suggest that COM is a significant migraine predictor, and thus imply the necessity for rigorous migraine prevention in COM patients, especially female and younger ones.

ObjectivesThis study aimed to determine colorectal cancer (CRC) risks among patients with gout through a follow-up study on a nationwide population-based cohort that included patients with gout and the general population in Taiwan.ParticipantFrom the Taiwan National Health Insurance Research Database, we identified 28 061 patients who were newly diagnosed with gout between 2000 and 2010 as the study cohort. We randomly selected 84 248 subjects matching in gender, age and baseline year as comparison cohort. The cohorts were followed up until CRC occurrence, withdrawal from the system of National Health Insurance, or Dec. 31, 2013.Primary and secondary outcome measuresCumulative incidences and incidence rate ratios (IRRs) of CRC between two cohorts were examined. The Cox proportional hazards model was used to evaluate risk factors associated with CRC development.ResultsDuring the 13-year follow-up, the incidence rate of CRC development in the gout cohort reached 2.44 per 1000 person-years, which was higher than the 2.13 per 1000 person-years in the control cohort (IRR=1.15; 95% CI 1.04 to 1.26). After adjusting for age, gender, urbanisation status and comorbidities, including hypertension, diabetes and hyperlipidaemia, gout showed no significant association with increased risk of CRC occurrence (adjusted HR=1.03; 95% CI 0.93 to 1.14).ConclusionsSimilar risks of CRC incidence were observed in patients with and without gout in Taiwan. Allopurinol and colchicine are commonly used as urate-lowering drug and anti-inflammation medication in Taiwan and had been shown to reduce the risk of CRC incidence. Thus, further pharmaco-epidemiological studies should be carried out to specifically assess the role of allopurinol in the relationship between gout and CRC.

Objective: The prevention of chronic kidney disease (CKD) progression is an important issue from health and financial perspectives. We conducted a single-year cross-sectional study to clarify the prevalence of CKD and its risk factors along with variations in these factors among five medical regions in Okayama Prefecture, Japan. Methods and Results: Data concerning the renal function and proteinuria as well as other CKD risk factors were obtained from the database of the Japanese National Health Insurance. The proportion of CKD patients at an increased risk of progression to end-stage renal disease (ESRD), classified as orange and red on the CKD heatmap, ranged from 6–9% and did not vary significantly by the regions. However, the causes of the increased severity differed between regions where renal dysfunction was predominant and regions where there were many patients with proteinuria. CKD risk factors, such as diabetes mellitus, hypertension, hyper low-density lipoprotein-cholesterolemia, obesity, smoking and lack of exercise, also differed among these regions, suggesting that different regions need tailored interventions that suit the characteristics of the region, such as an increased health checkup ratio, dietary guidance and promotion of exercise opportunities. Conclusions: Approximately 6–9% of people are at an increased risk of developing ESRD (orange or red on a CKD heatmap) among the population with National Health Insurance in Okayama Prefecture. The underlying health problems that cause CKD may differ among the regions. Thus, it is necessary to consider intervention methods for preventing CKD progression that are tailored to each region’s health problems.

Inflammatory Bowel

Background: Prior literatures have shown inflammatory bowel disease (IBD) could increase fibromyalgia (FM) risk. However, studies about gender and age distributions of FM risk among patients with IBD are rare. With large study samples, this study aimed to evaluate the FM risk among IBD patients with different gender and different age. Objective: We aim to estimate the FM risk among male and younger IBD patients with a large patient sample. Study Design: A retrospective cohort study was arranged in this research. Setting: The data used in this research were selected from the Taiwan National Health Insurance Research Database (NHIRD). Methods: From the Taiwan NHIRD, we selected 4,510 patients with IBD and 18,040 randomly gender- and age-matched patients without a history of IBD from the beginning of 2000 to the end of 2005 to analyze the development of FM over a 12-year follow-up period (2000– 2011). The Cox regression model was used to assess the effects of IBD on the risk of FM by adjusting for gender, age, and comorbidities, including hypertension, diabetes, hyperlipidemia, depression, anxiety, and sleep disorder. Results: After adjusting suitable covariates, the IBD patients had a greater FM risk (adjusted hazard ratio [aHR] 1.70, 95% confidence interval [CI] 1.59–1.83) than the controls. Male IBD patients had a higher FM risk than female IBD patients did (aHR 2.00, 95% CI 1.79–2.23 and aHR 1.52, 95% CI 1.38–1.67, respectively). The greatest age-specific FM risk occurred in the youngest IBD subgroup (≤ 39 years old) (aHR 1.92, 95% CI 1.68–2.19). Limitations: The information about personal behaviors was unobtainable in the Taiwan NHIRD. Other risk factors for cardiovascular disease that might augment FM cannot be excluded entirely in this study. Conclusion: IBD is disclosed to be correlated with an enhanced risk to develop FM, particularly in male and younger IBD patients. For preventing FM, it is necessary to pay more attention to the management of the IBD patients. Future researches are needed to further confirm the findings in this study.

ObjectiveBoth physical diseases such as infection and chronic pain and psychological disorders such as depression have been associated with herpes zoster (HZ) reactivation. However, the relationship between de Quervain syndrome (DQS), a painful tenosynovitis and HZ remains unclear. We investigated whether DQS increases the risk of HZ reactivation.DesignA retrospective population-based cohort study.SettingTaiwan.ParticipantsWe used a subset of Taiwan’s National Health Insurance Research Database, the Longitudinal Health Insurance Database which contains the registration files and original claims data of 1 million randomly selected individuals from the National Health Insurance programme. The case group in this study comprised patients newly diagnosed with DQS between 2000 and 2012. Individuals without DQS comprised the control group. Cases and controls were 1:1 matched by age, sex and index year (defined as the year of DQS diagnosis).ResultsApproximately 55% of the participants were ≤49 years. Most participants were women (77%). The incidence rate of HZ in the DQS group was 8.39 per 1000 person years. After adjustments for age, sex and comorbidities, patients with DQS had a 1.30 times higher risk of HZ reactivation than the control group. Stratification analysis revealed taht DQS increases the HZ risk in individuals ≤64 years, women, and patients without comorbidities.ConclusionDQS is associated with an increased risk of HZ. Clinicians should be aware of this risk when dealing with patients with DQS, particularly in young adults.
