This house believes that prednisolone should be the first line for glucocorticoid replacement in adrenal insufficiency: The case FOR…

Meeran Karim

Natural hormones are continuously secreted and metabolised and thus have a short half-life. When administered exogenously, either the natural hormone needs to be administered often, or analogues with longer half-lives are given. For insulin, slow release (zinc suspensions) have been used, and more recently, the molecule has been extensively modified to give longer lasting insulins. Similarly, hydrocortisone can be given as a slow release or modified release preparation, or the...

Endocrinologists as teachers: integrating teaching and practice in the real world

Meeran Karim

Endocrinologists are ideal teachers of physiology and biochemistry, major aspects of the underpinning of the science behind clinical practice. There are many methods that are successful in imparting this core knowledge to our medical students. Patients with endocrine disease also display symptoms and signs that that give clues to diagnoses, and the subject is ideal to serve as a broad general medical education.Evidence that teachers are effective comes f...

Investigating and diagnosing Cushing’s syndrome: not as straightforward as it seems?

Meeran Karim

Cushing’s syndrome is rare at about 20 per million of population each year. Patients with Cushing’s syndrome complain of increased weight, high blood pressure and diabetes. Obesity not caused by Cushing’s is becoming very much more common, and obesity itself can also cause high blood pressure and diabetes. Distinguishing common simple obesity from rare Cushing’s disease can be difficult. Patients with simple obesity are now able to surf the internet, and fi...

Preventing and managing long term complications of acromegaly

Meeran Karim

The treatment of Acromegaly includes radiotherapy, surgery, and medical treatment to reduce GH levels. The aim of treatment is to reduce GH levels to a “safe” level. The secretion of GH in normal individuals is pulsatile, so that most normal people have concentrations of GH close to zero for most of the time, with concentrations rising to about 6 ng/ml three or ten times per day (approx 20 mU/l). The height and frequency of these GH peaks is variable. However because...

Cannulated prolactin is useful to confirm hyperprolactinemia and to minimize inappropriate imaging

Almazrouei Raya , Meeran Karim

Background: Current Endocrine Society guideline recommends a single prolactin level to confirm the diagnosis of hyperprolactinemia. This may lead to over diagnosis and inappropriate imaging. Our institution protocol is to repeat the prolactin and measure macroprolactin. If the second prolactin is elevated, then a cannulated prolactin to role out venipuncture stress effect is undertaken.Methods: Data were collected for 49 patients between January 2017 to ...

Sheehan’s syndrome in a man

Almazrouei Raya , Meeran Karim

Background: The blood supply of the pituitary gland comes via a portal circulation from the hypothalamus. During pregnancy, the anterior pituitary gland enlarges but the blood supply cannot increase, as it is derived from a capillary plexus. The pituitary is thus vulnerable to arterial pressure changes and infarction secondary to hypotension. We describe a case of a male patient with large pituitary adenoma who developed Sheehan’s like syndrome due to adenoma infarction s...

Enteric coating delays the absorption of prednisolone variably and should not be used

Zhang Jennifer , Choudhury Sirazum , Meeran Karim

Once daily oral prednisolone has been shown to mimic the normal circadian rhythm better than other glucocorticoids. Our advice is to take prednisolone first thing on waking and before breakfast to try to mimic the normal circadian rhythm as closely as possible. The leaflet that comes with prednisolone suggests that it should be taken with food. Enteric-coated prednisolone (EC) is believed to be kinder on the stomach, but there is no evidence for its use. We compared EC with st...

Lodotra (delayed release prednisone) is variably absorbed, and should not be used in adrenal insufficiency

Zhang Jennifer , Choudhury Sirazum , Meeran Karim

Replacing glucocorticoids in patients with adrenal insufficiency is challenging, as endogenous cortisol levels rise before waking. Currently we use steroid replacement first thing in the morning. Administration of a delayed release preparation last thing at night, if reliable, could mimic the rise in cortisol that occurs before waking. Lodotra is a modified release prednisone that has a delay in the onset of action, and when given last thing at night, might cause a rise in lev...

Primum Non Nocere – the need for appropriate assessment before starting testosterone therapy

Moriarty Maura , Meeran Karim , George Emad

A 41 year old Emirati man was reviewed in January 2016 for hypercholesterolaemia managed on diet alone, but direct questioning revealed gradual onset erectile dysfunction over 2 years, treated by a urologist elsewhere. Initial response to Cialis had waned over 18 months. Testosterone replacement (Nebido) had been initiated in June 2015 on the basis of one low morning total testosterone of 3.89 nmol/L (normal range 8.64 – 29). SHBG and prolactin...
