RESUMO
Objectives: Glucocorticoid steroids are frequently prescribed, and side effects are well-known, such as glucocorticoid-induced osteoporosis. Our aim was to estimate the nationwide trend in the prevalence of glucocorticoid steroid prescriptions over 17 years and to elucidate the proportion of patients on long-term glucocorticoid steroid therapy who receive active bone protective therapy. As well as to examine which medical specialties prescribe glucocorticoid steroids the most. Methods: This study was a retrospective observational registry study extended over 17 years (2003-2020). Data were retrieved from the Icelandic Prescription Medicine Register on all delivered glucocorticoid steroids (Anatomic therapeutic chemical code: H02AB) for oral use. Long-term users were defined as those who annually received ⩾90 defined daily doses of glucocorticoid steroids. Results: Annually, 3.8% of the population received oral glucocorticoid steroids, from 3.3% in 2006 to 4.3% in 2017. Prednisolone was most frequently prescribed. Females dispatched glucocorticoid steroid prescriptions more often than males (55.8%). Males and females reached their peak prevalence between the ages of 60 and 70. General practitioners most often prescribe glucocorticoid steroids, followed by physicians in training, rheumatologists, internists, and medical students. Of those who received prescriptions for glucocorticoid steroids, 12.2%-18.1% were classified as long-term users. A declining number of patients have been receiving bone-protective therapy in recent years. Only 13.0% of chronic users received bone protective therapy in 2020. Conclusion: The use of glucocorticoid steroids has increased during the last 2 decades despite improvements in treatment for inflammatory disorders. The prevalence of long-term users has remained stable. Meanwhile, the use of parallel active bone-protective therapy among long-term users of glucocorticoid steroids is declining. Thus, improvements in prophylaxis for corticosteroid-induced osteoporosis are urgently needed for patients who require long-term treatment with glucocorticoid steroids.
RESUMO
We examined changing patterns in cancer incidence and deaths in diabetes compared to the background population. A total of 457,473 patients with type 2 diabetes, included between 1998 and 2014, were matched on age, sex, and county to five controls from the population. Incidence, trends in incidence and post-cancer mortality for cancer were estimated with Cox regression and standardised incidence rates. Causes of death were estimated using logistic regression. Relative importance of risk factors was estimated using Heller's relative importance model. Type 2 diabetes had a higher risk for all cancer, HR 1.10 (95% CI 1.09-1.12), with highest HRs for liver (3.31), pancreas (2.19) and uterine cancer (1.78). There were lesser increases in risk for breast (1.05) and colorectal cancers (1.20). Type 2 diabetes patients experienced a higher HR 1.23 (1.21-1.25) of overall post-cancer mortality and mortality from prostate, breast, and colorectal cancers. By the year 2030 cancer could become the most common cause of death in type 2 diabetes. Persons with type 2 diabetes are at greater risk of developing cancer and lower chance of surviving it. Notably, hazards for specific cancers (e.g. liver, pancreas) in type 2 patients cannot be explained by obesity alone.
