Background: The short Synacthen test (SST) is commonly used for assessing adrenal reserve. Depending on the cause, we often use serial SSTs in current practice, to assess whether people with adrenal insufficiency (AI) have adrenal axis recovery. We aimed to explore if baseline cortisol levels were a suitable screening test for recovery in people with AI rather than using serial SST in all cases.Methods: We retrospectivel...

Objectives: Eversense XL is a fully implantable sensor for continuous glucose monitoring (CGM) that lasts for up to 180 days. Our objective was to perform a survey on user acceptance and satisfaction among our type 1 diabetic patients who had been using the Eversense XL CGM for at least 3 months.Methods: A questionnaire was devised in which the patients were asked about their experience with the Eversense XL CGM, including:-Compari...

Background: Urinary concentrations of the major progesterone metabolite pregnanediol glucuronide (P3G) are used clinically and in research to monitor ovulation. This ELISA is laborious and costly. If it could be replaced by the automated sensitive chemiluminescence assays routinely used for serum this would be of great value.Objective: We aimed to determine the validity of urine progesterone as measured by two widely used automated assays in comparison t...

Objectives: Free thyroxine (fT4) measurements are performed to detect thyroid disorders and monitor treatment. FT4 is measured using automated immunoassays (IAs) which face established analytical challenges due to low serum concentrations in the picomolar range and the precarious equilibrium between free and bound T4 (to thyroid-binding globulin (TBG) and (pre-)albumin). Furthermore, IAs are known to be affected by the composition of the serum sample (matrix-effects), which ca...

Objectives: This prospective study aimed at investigating (1) the prevalence of vitamin D deficiency and insufficiency in diabetic adolescents and children in a multi-ethnic cohort, and (2) any association between vitamin D status and ethnic background, glycaemic control (HbA1C), biomarkers of metabolic bone health and lipids.Methodology: Venous blood was drawn from 199 patients with type 1 diabetes (mean age ± SD, 8.2 ± 3.7 years) and 48 patients ...

Background: As adoption of continuous glucose monitoring (CGM) continues to expand, lot more studies are investigating the effects of CGM on HbA1C and hypoglycaemia risks in people with Diabetes Mellitus (PwD). In PwD, established benefits of usage of CGM along with digital diabetes self-management and education (DSME) program in Indian real-world context are scarce. OneCare compares patients engaged in its “IMPACT’ DSME program alone vs program assisted by CGM.<...

Introduction: Diabetes mellitus secondary to exocrine pancreas diseases (pancreatogenic DM) has an unknown incidence and is considered underdiagnosed. Our objective was to evaluate the glycemic control parameters in patients with pancreatogenic DM who started Flash glucose monitoring (FGM).Methods: Prospective, observational study in a Spanish hospital. Patients with pancreatogenic DM who started FGM from January 2021 to August 2022 were recruited. Patie...

A 52-year-old patient with a history of secondary progressive multiple sclerosis was referred to our endocrine vetting service with deranged thyroid function tests (TFTs). Medicines reconciliation demonstrated that the patient was currently on regular fampridine and carbamazepine only. TFTs checked in the community revealed a free T4 of 65.8pmol/l (12.0-22.0pmol/l) with a TSH of 2.03mU/l (0.27-4.20mU/l) and a free T3 of 5pmol/l (3.1-6.8pmol/l). 25-OH vitamin D and vitamin B12 ...

Case history: A 47 year old male presented to his GP with non-specific symptoms of fatigue and weight gain. Thyroid function tests revealed elevated TSH (28.4 mU/l) with normal Free T4 (14.3 pmol/l). Anti-TPO antibodies were undetectable. A presumptive diagnosis of subclinical hypothyroidism was made and he was commenced on Levothyroxine which was titrated over 9 months to 150 mcg/d given a persistently elevated TSH. The patient was unable to tolerate this dose due to the deve...
