This case series adds to the growing literature demonstrating that RTX, administered in our patients with concomitant methylprednisolone, is safe and clinically effective in the treatment of active, moderate to severe and sight-threatening GO. Randomized controlled trials are now needed to confirm the efficacy of RTX for GO.
Background: Agranulocytosis is a serious side effect of antithyroid drugs. Objective: To ascertain the knowledge of patients and review the quality of information available on the internet. Methods: A questionnaire survey was performed for patients receiving antithyroid drugs. Patients attending endocrine clinics who were receiving antithyroid drug treatment (group A, n = 33) were interviewed. A further national cohort of patients (group B, n = 100) treated with antithyroid drugs, participated in an online survey. Results: 60.9% of responders were not aware of the common symptoms of agranulocytosis. 18.6% had never received any information about side effects. Of the 108 patients who recalled receiving information, 30% rated the quality as ‘poor' or ‘not good at all'. Structured interviews of group A patients revealed that almost half (45.5%, 15/33) had experienced symptoms that could be indicative of agranulocytosis, but only 53.3% (8/15) had a blood count checked. A review of 20 selected patient information internet sites revealed a significant variation in advice given to patients. Conclusions: Inadequate knowledge about agranulocytosis among patients receiving antithyroid drug treatment is common. The available information on the internet is variable and inconsistent.
Summary
Oral calcium salts are recommended for the treatment of chronic hypoparathyroidism (HypoPT), although dosimetry is variable between individual patients and clinicians. However, patient feedback on calcium salts can be negative, particularly due to gastrointestinal side effects and hypercalciuria‐related complications. We begin with a clinical case of a HypoPT patient taking oral calcium salts following thyroid surgery, who requested support in reducing her dose of these with a view to stopping entirely. To evaluate her request, we first describe the usual treatment of HypoPT according to current guidance and then present data from (a) a case note review of a cohort of 24 HypoPT patients managed with a “no calcium” treatment regimen by single physician (b) a comprehensive online survey of HypoPT patients’ treatment and experiences (n = 330). The case note review found that target range serum calcium levels were successfully achieved in all 24 patients since transitioning to a “no calcium” regimen, without any breakthrough hypocalcaemia‐related symptoms, the development of new renal stones, the occurrence of calcium‐related hospital admissions or the finding of significant hypercalciuria. The online survey identified 36% of HypoPT patients who continued to take activated vitamin D, but had discontinued calcium supplements. HypoPT patients not currently taking calcium reported a significantly lower prevalence of adverse effects and outcomes, both compared with their previous experiences whilst taking calcium and also compared with the 64% of patients who continued to take oral calcium. We conclude that, subject to methodological limitations, there are significant issues of tolerability arising from conventional calcium‐based treatment regimens for patients with chronic HypoPT. For selected patients, it may be reasonable to facilitate a managed therapeutic transition to “no calcium” regimen, and we also propose that calcium‐based regimes be prospectively evaluated against calcium‐free (or calcium‐low) alternatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
