Abstract

OBJECTIVE: In patients with Cushing's syndrome (CS) cardiovascular complications determine a mortality rate four times higher than in an age- and gender-matched population. Therefore, we calculated the global cardiovascular risk in patients with CS. DESIGN AND PATIENTS: We applied the World Health Organization--International Society of Hypertension (WHO/ISH) 1999 guidelines for the estimation of cardiovascular risk in 38 females and 11 males with CS; 27 pituitary adenomas, 15 adrenal adenomas, four adrenal carcinomas and three ectopic ACTH-secreting tumours. The risk of major cardiovascular events was estimated considering the combined effect of several risk factors (hypertension, diabetes, etc.), organ damage (left ventricular hypertrophy (LVH), proteinuria, etc.) and associated pathologies. Four categories of absolute cardiovascular disease risk were defined (low, medium, high, very high). RESULTS: Eighty per cent of patients presented a 'high' or 'very high' cardiovascular risk; 85.1% of the patients were hypertensive with a mild-moderate hypertension (68%). Forty-seven per cent of patients were diabetics and 41.3% were obese. Hyperlipidaemia was less frequent (37.5%). Fasting glycaemia was the only cardiovascular risk factor that correlated with a degree of hypercortisolism. Duration of disease correlated with the presence of obesity (P < 0.0008) and hypertension (P < 0.03) but not with the presence of diabetes or dyslipidaemia and seemed to be the only significant predictor of cardiovascular risk (P = 0.03). CONCLUSIONS: Patients with active CS present a remarkably increased cardiovascular risk. Considering that the biochemical cure of hypercortisolism is often difficult to obtain, especially in Cushing's disease, and that cardiovascular risk could persist even after the 'cure', control of risk factors should be one of the primary goals of the therapy.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Among patients with endogenous Cushing syndrome, 20% to 45% have diabetes and 10% to 30% have defective glucose tolerance, so overall prevalence of glucose metabolism impairment can approach 70%.

    “From % to % of patients with endogenous CS have DM, and % to % have defective glucose tolerance, so the overall prevalence of glucose metabolism impairments can come close to %, as shown in Table  (, , -).”
  • Fasting plasma glucose may not suffice to assess glucose homeostasis in Cushing syndrome because 64% of patients with endogenous Cushing syndrome and diabetes have normal fasting glucose levels.

    “Fasting plasma glucose (FPG) level may not suffice to assess glucose homeostasis in CS because more than one in two patients (%) with endogenous CS and DM have normal FGP levels () and because an oral glucose tolerance test (OGTT) is not always performed in patients with apparently normal fasting glycemia ().”
  • The onset of diabetes does not seem to correlate with the duration of endogenous Cushing syndrome.

    “Diabetes can develop irrespective of the etiology of cortisol excess in patients with endogenous CS (, ), and its onset does not seem to correlate with the duration of the latter disease ().”
  • The severity of hypercortisolism correlates with the presence of insulin resistance and diabetes, as shown by an association with higher urinary free cortisol levels, though not all studies found this.

    “Generally speaking, the severity of hypercortisolism correlates with the presence of IR and DM, as evidenced by an association with higher urinary free cortisol (UFC) levels (, ), though this was not identified in all studies (, ).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
