RESUMO
BACKGROUND: The treatment of hyperthyroid Graves' disease (GD) varies considerably among geographic areas. In this study, we aimed to evaluate practice patterns and treatment outcomes in Thai patients with hyperthyroid GD. METHODS: A retrospective cohort study over 35 years (1985-2019) in patients with hyperthyroid GD was conducted. The trends of treatment options were compared periodically during the study period and the overall remission rate from each option was determined. RESULTS: A total of 2736 hyperthyroid GD patients were treated and followed-up for at least 3 months over the study period (female 82.0%, mean age at diagnosis 36.3 ± 12.0 years, median duration of follow-up 74.5 months). Anti-thyroid drug (ATD) was the most commonly used treatment (78.0%), followed by RAI (21.0%), and surgery (1.0%). There was a significant downward trend for surgery, from 12.3% in the 1980s to only 0.2% in last phase of the study period. The preference for RAI therapy has also decreased in the last 5 years. Among ATD-treated patients, the remission rate was achieved only in 30.7 and 16.0% of all ATD-treated patients were eventually treated with RAI. Spontaneous hypothyroidism developed in 2.7% of the ATD-treated patients during a follow-up period. Almost all RAI-treated patients (97.1%) developed hypothyroidism. CONCLUSIONS: Our present study highlighted the changing landscape of primary treatments for hyperthyroid GD toward ATD and the sharp downward trend in the surgical option. Even though ATD was associated with a low remission rate, it was preferred by many patients and physicians. The use of RAI as the primary treatment decreased in the last decade. However, RAI was a very effective treatment for Graves' hyperthyroidism but will inevitably induce hypothyroidism and a requirement for life-long replacement therapy.
RESUMO
Trends in influenza and pneumococcal vaccine coverage in Thai patients with type 2 diabetes mellitus 2010-2018: Experience from a tertiary diabetes center in Bangkok. BACKGROUND: Routine vaccination is an important part of preventive services in treating patients with type 2 diabetes (T2DM). There are no available data in temporal trends of vaccination coverage rates in both influenza and pneumococcal vaccines among Thai patients with T2DM. AIM: This study aimed to elucidate influenza and pneumococcal vaccination trends and to identify factors that affect vaccination rates in those patients. METHOD: A retrospective study of randomly medical records stratified by 13 diabetologists was conducted in patients with T2DM from 2010 to 2018 at Theptarin Hospital, a private multi-disciplinary diabetes center in Bangkok. Adherence to influenza and pneumococcal vaccinations according to current guidance on adult immunization in Thailand had been studied. The rate of both vaccinations from each diabetologist had also been recorded. RESULTS: A total of 2114 medical records (female 51.7%, mean age 65.2 ± 12.8 years, BMI 26.5 ± 4.6 kg/m2, A1C 7.1 ± 1.3%, median duration of diabetes 13 years) were retrospectively reviewed covering a 9-year period. We audited 3554 selected outpatient visits for influenza and pneumococcal vaccinations rates as key performance index in each year. The overall vaccination rate was 39.6% for influenza, 17.4% for the pneumococcal vaccine, and only 13.7%, for both vaccines. The trends of influenza vaccination rates increased from 32.9% in 2010 to 52.2% in 2018 but the trends of pneumococcal vaccination rates were relatively stable at less than 20%. The rate of both vaccinations varied considerably from 0 to 44% among our diabetologists. Age ≥ 65 years, duration of DM ≥ 15 years, the presence of chronic respiratory disease, and moderate to severe Charlson Comorbidity Index (CCI) score were positively associated with both received vaccinations. CONCLUSIONS: The completeness and timeliness of influenza and pneumococcal vaccinations were unsatisfactory in Thai patients with T2DM. More efforts are needed to increase both influenza and pneumococcal vaccination rates.
