Endocrine Disorders in Autoimmune Rheumatological Diseases: A Focus on Thyroid Autoimmune Diseases and on the Effects of Chronic Glucocorticoid Treatment

Autoimmune rheumatological diseases’ incidence and prevalence have risen over the last decades and they are becoming increasingly important worldwide. Thyroid autoimmune diseases share with them an imbalance in the immune system that lead to a pro-inflammatory environment. Usually this is the result of a multi-factorial process. In fact, it includes not only a possible genetic predisposition, but also environmental causes like microbiota dysbiosis, diet rich in processed foods, exposure to toxicants and infections. However, many aspects are currently under study. This paper aims to examine the factors that participate in the developing of rheumatological and thyroid autoimmune diseases. Moreover, as glucocorticoids still represent a leading treatment for systemic autoimmune rheumatological diseases, our secondary aim is to summarize the main effects of glucocorticoids treatment focusing on iatrogenic Cushing’s syndrome and glucocorticoids’ withdrawal syndrome.

Safety of epidural steroids: a review

Spine disease is one of the most common musculoskeletal diseases, especially in an aging society. An epidural steroid injection (ESI) is a highly effective treatment that can be used to bridge the gap between physical therapy and surgery. Recently, it has been increasingly used clinically. The purpose of this article is to review the complications of corticosteroids administered epidurally. Common complications include: hypothalamic-pituitary-adrenal (HPA) axis suppression, adrenal insufficiency, iatrogenic Cushing's syndrome, hyperglycemia, osteoporosis, and immunological or infectious diseases. Other less common complications include psychiatric problems and ocular ailments. However, the incidence of complications related to epidural steroids is not high, and most of them are not serious. The use of nonparticulate steroids is recommended to minimize the complications associated with epidural steroids. The appropriate interval and dosage of ESI are disputed. We recommend that the selection of appropriate ESI protocol should be based on the suppression of HPA axis, which reflects the systemic absorption of the corticosteroid.
