Antenatal thyroid hormone therapy and antithyroid drug use in Norway from 2004 to 2018

Objective Thyroid disease during pregnancy is associated with adverse pregnancy outcomes and suboptimal fetal development. During the last decades, guidelines for diagnosing thyroid disease during pregnancy have changed considerably and there has been increased awareness. This study aimed to describe the prevalence of thyroid disease treatment over time among pregnant women in Norway. Design Nationwide register-based study. Methods We combined historical data from the Medical Birth Registry of Norway and the Norwegian Prescription Database, identifying pregnant women using thyroid therapy from 2004 to 2018. Results A total of 855,067 pregnancies were included in the analyses. The proportion of women using thyroid hormone replacement therapy during pregnancy increased from 1.46% (n  = 800) in 2004 to 3.57% (n  = 1940) in 2018. The proportion of women using antithyroid medications also increased from 0.04% (n  = 20) in 2004 to 0.10% (n  = 56). During these 15 years, the mean maternal age increased by 0.9 years. When adjusting for age, the risk for being on thyroid hormone replacement therapy during pregnancy increased by an average of 5% per year (odds ratio: 1.05, 95% CI: 1.05–1.05). Conclusion During the recent 15 years, there has been a substantial increase in the use of thyroid hormone therapy in Norwegian pregnant women. We speculate that this could be due to an increased awareness in combination with overdiagnosis because of inappropriate diagnostic criteria. To truly understand the possible causes and consequences of this development, further research is warranted.publishedVersio

TREATMENT OF CLOSTRIDIUM DIFFICILE- ASSOCIATED DISEASE

Clostridium difficile is a Gram-positive, spore-forming, anaerobic bacillus that is widely distributed in the environment, but is found as a part of a normal large bowel flora in approximately 3% of normal adults. C. difficile produces two protein exotoxins: toxin A and toxin B. Both toxins are responsible for causing the sings and symptoms of disease.C. difficile is now thought to be responsible for a spectrum of diseases, ranging from asymptomatic colonization to diarrhea of varying severity, life-threatening colitis, often as a consequence of long-term antibiotic exposure. This spectrum has become known as C. difficile-associated disease (CDAD).Treatment of Clostridium difficile-associated disease demand administration of effi-cient antibiotics (vancomycin, metronidazole), anion exchange resins and probiotics (Lactobacillus spp., Saccharomyces boulardii)
