Background: Pleuro-pulmonary inflammatory fibrotic syndrome is a rare but recognised complication of dopamine agonist (DA) therapy in Parkinson’s disease. Here, we describe a case of asymptomatic pulmonary fibrosis, presumed secondary to DA therapy, in a patient treated with cabergoline for an invasive macroprolactinoma.Case report: A 47-year-old previously fit man was admitted as an emergency with a 3 days history of headache followed by collapse. ...

We report of a 71-year-old gentleman first diagnosed with acromegaly in 1981. He was initially treated with hypophysectomy and radiotherapy and subsequently bromocriptine therapy; requiring increments in the dose over the next ten-years (1981–1991) by which time he remained on maintenance dose of 10mgs thrice-daily. Bromocriptine was tolerated well and the patient had no side effects. Treatment was weaned off due to improvement in patient’s symptoms and growth hormon...

For more than a dozen years, a major combined biological and clinical research endeavour has been dedicated to the set up of new therapeutics based upon cell and gene therapy for neurodegenerative diseases. This research essentially takes into account two determinant characteristics of all these diseases, that can be briefly summarised as follows: 1. a neurodegenerative disease is due to the loss of one or a small number of specific populations of neurones, allowing in some ca...

Background: Insulinoma is the most common cause of hypoglycaemia due to endogenous hyperinsulinemia. However, they can sometimes present with atypical features. Some of the patients can also develop serious adverse effects to medical treatment. We present a case with atypical features and further developed serious adverse effects with medical treatment for insulinoma.Case presentation: A 42-year-old Caucasian female presented with recurr...

Aim: To determine the prevalence of impulse control disorder (ICD) in patients with Cushing’s disease (CD) treated with cabergoline (CBG) compared to CBG-naive patients with CD.Methods: We performed a cross-sectional study in patients with CD followed at 5 referral centers based in Istanbul. Eligible patients with CD were those with current CBG treatment for ≥ 3 months. Eligible controls were CBG-naive patients with CD that were matched for ag...

Background: Dopamine agonists (DAs) were associated with valvular dysfunction in patients with Parkinson’s disease due to their fibrotic effect through the serotoninergic receptor. It is more difficult to prove the same effects in patients with prolactinoma due to the lower doses, variable doses and the longer follow-up period. Aim: To assess echocardiographic features in patients with prolactinoma under DA treatment.Methods: ...

Late-onset hypogonadism (LOH) remains a debatable entity in terms of diagnosis and management. However, the finding of primary hypogonadism (PHG) in ageing men, in the absence of organic cause, provides an unequivocal biochemical diagnosis. Indeed, it has been established in European Male Ageing Study (EMAS) that PHG, and not secondary hypogonadism, is strongly associated with advanced age and multi-comorbidities. That would be consistent with the underlying pathophysiology of...

Introduction: The obstructive sleep apnea syndrome (OSAS) has a well-documented association with increase cardiovascular morbidity and mortality. The patients with OSAS have a high prevalence of hypertension and the OSAS may present similar to a pseudo-pheochromocytoma (PPH). We report two cases with PPH caused by OSAS; a common medical condition which is less recognized as a cause of raised catecholamines.Observations: Case 1: 54 year-old man had a hist...

72 years old patient was send to endocrinological outpatients clinic with suspect to nevroendocrine tumor (NET) with chromogranin A (CgA) level 379 μg/l (range 19.4–98.1). She described abdominal colic and diarrhoea lasting 2–3 hours after meals accompanied by dizziness, drenching sweat and lower blood pressure for the last 2 years. Comorbidities: arterial hypertension, chronic gastritis, heart failure and osteoporosis. Medications: omeprazole, losartan, pravast...

Introduction: Dopamine agonists (DAs) consisting of cabergoline (CAB) or bromocriptine is the primary therapy in prolactinomas. DAs are also used in Parkinson’s disease and restless leg syndrome with much higher doses. As a result of reports related to doses in these patients, it is known that long term use of DAs can lead to fibrotic syndromes affecting heart and lung. Cardiac valvulopathies are the most common investigated side effects but there are case reports of ple...
