Effect of Roxadustat on Thyroid Function in Patients With Renal Anemia.

CONTEXT: Roxadustat, a hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor, a recently developed class of drugs for treatment of anemia in chronic kidney disease (CKD), is reported to have a structure unlike that of other HIF-PH inhibitors but similar to that of triiodothyronine and bind to the thyroid hormone receptor in vitro. However, reports on the effects of roxadustat on thyroid function are limited and not detailed, and it remains unknown whether other HIF-PH inhibitors also affect thyroid function. OBJECTIVE: To compare the effect of roxadustat with daprodustat, another HIF-PH inhibitor, on thyroid function in patients with renal anemia in CKD. METHODS: This retrospective observational study included a total of 26 patients with anemia in CKD who were treated with roxadustat or daprodustat; thyroid-stimulating hormone (TSH) and free thyroxine (FT4) were measured before and after treatment with the drugs. RESULTS: After initiation of roxadustat, TSH showed a significant decrease (2.4732 [1.7858-4.9016] µIU/mL before treatment and 0.659 [0.112-2.005] µIU/mL after treatment, P < .05); FT4 showed a significant decrease (0.93 [0.84-1.05] ng/dL before treatment and 0.70 [0.53-0.85] ng/dL after treatment, P < .01). After daprodustat initiation, neither TSH nor FT4 showed a significant change (TSH: 3.044 [1.853-4.171] µIU/mL before treatment and 2.893 [1.866-4.894] µIU/mL after treatment, P = .635; FT4 was 0.93 [0.81-1.00] ng/dL before treatment and 0.97 [0.87-1.05] ng/dL after treatment, P = .328). CONCLUSION: Roxadustat decreases TSH and FT4 levels while daprodustat does not.

Stigma evaluation for diabetes and other chronic non-communicable disease patients: Development, validation and clinical use of stigma scale - The Kanden Institute Stigma Scale.

AIMS/INTRODUCTION: The aim of this study was to develop a scale to evaluate disease stigma in patients with lifestyle-related chronic non-communicable diseases (LCNCDs), which we named the Kanden Institute Stigma Scale (KISS), and to consider its possible clinical application for patients with diabetes. MATERIALS AND METHODS: An initial 90 questions were drafted and categorized into six subscales according to the manifestations of stigma. The final version of the KISS was developed as a 24-item questionnaire comprising four items for each subscale. RESULTS: A total of 539 outpatients including 452 patients with diabetes and 87 patients without diabetes were recruited. Construct validity was confirmed by assessing the correlation with previously established measures. Confirmatory factor analysis showed the KISS to have good model fitness (adjusted goodness-of-fit index = 0.856). Test-retest reproducibility analysis showed that the intraclass coefficient of the first and a second KISS was 0.843 (P < 0.001), indicating excellent reproducibility. The KISS showed higher scores for patients with diabetes than for patients without diabetes (12.23 ± 0.49 vs 5.76 ± 0.73, P < 0.05). The KISS score was significantly higher in type 1 and type 2 diabetes patients taking insulin therapy than in type 2 diabetes patients not taking insulin (P < 0.05). CONCLUSION: The KISS is a validated and reliable questionnaire for assessment of stigma among patients with diabetes as well as other lifestyle-related chronic non-communicable diseases, and might contribute to identifying and rectifying diabetes stigma, as well promoting awareness among health care professionals of this very consequential health problem.

Lifestyle changes as a result of COVID-19 containment measures: Bodyweight and glycemic control in patients with diabetes in the Japanese declaration of a state of emergency.

To clarify the association between lifestyle changes as a result of coronavirus disease 2019 containment measures and changes in metabolic and glycemic status in patients with diabetes, a cross-sectional, single-center, observation study was carried out. A self-reported questionnaire was provided to ascertain the frequency of various lifestyle activities before and after the coronavirus disease 2019 containment measures in Japan. Among 463 patients, change in glycated hemoglobin was significantly associated with change in bodyweight. After stratification by age 65 years, binary logistic regression analysis showed that increased frequency of snack eating increased bodyweight (odds ratio 1.709, P = 0.007) and glycated hemoglobin (odds ratio 1.420, P = 0.025) in the younger group, whereas in the older patients, reduced walking activities resulted in weight gain (odds ratio 0.726, P = 0.010). In conclusion, changes in eating behavior and physical activity increased bodyweight and reduced glycemic control among diabetes patients, but by different processes depending on age under the coronavirus disease 2019 containment measures in Japan.
