Objective

Treatment with dopamine agonists has been associated with cardiopulmonary fibrotic reactions, predominantly in patients treated for Parkinson's disease. To our knowledge, these reactions have previously not been associated with low-dose cabergoline treatment for hyperprolactinaemia.

Method

A case of constrictive pericarditis in a patient treated with cabergoline for hyperprolactinaemia is presented. The patient has been treated at a county hospital and a university hospital in southern Sweden.

Results

A 20-year-old woman with a 3-year history of amenorrhoea was referred to the department in 1992. From 2001 to 2005, she was given cabergoline, 0.5–1.5 mg/week. In 2005 a pericardectomy was performed due to fibrotic, constrictive pericarditis.

Conclusions

Our present case suggests that constrictive pericarditis may develop even on low-dose cabergoline, which might indicate that this reaction, as opposed to valvular fibrosis, is not mediated by a 5-HT2B agonistic mechanism.

Objective:

Autonomous cortisol secretion and possible autonomous cortisol secretion (ACS/pACS) are associated to an increase of cardiovascular risk factors such as hypertension, diabetes mellitus and dyslipidaemia. To our knowledge, the prevalence of smoking, another well-established risk factor for cardiovascular disease, has not been studied in detail in people with ACS/pACS or adrenal incidentalomas.

Methods:

Patients with adrenal incidentalomas were examined with the 1-mg overnight dexamethasone suppression test (cortisolONDST). Information about current smoking was collected from the patient’s records.

Results:

We studied 1044 patients, of whom 370 (35%) were current smokers. Of these, 22% had bilateral AI compared to 12% of the non-smokers (P < 0.001). Among patients with unilateral adrenal incidentalomas, smokers had larger adrenal incidentalomas than non-smokers (22 mm vs 19 mm, P < 0.001). Smokers also more often had cortisolONDST ≥50 nmol/L than non-smokers, 54% vs 40% (P < 0.001), a finding independent of the size of the adrenal incidentaloma in patients with unilateral adrenal incidentalomas.

Conclusions:

In the present study of patients with adrenal incidentalomas, the prevalence of current smoking was higher than in the general population. Furthermore, smokers had larger unilateral adrenal incidentalomas, more often bilateral adrenal incidentalomas, and more frequently ACS/pACS. Whether smoking is a risk factor for adrenal incidentalomas and ACS/pACS or our findings are due to case selection needs to be further studied.
