High serum levels of cholesterol and triglycerides are risk factors for coronary heart disease and are strongly related to several haemostatic parameters. Thyroid disorders are a frequent feature in hyperlipidemic patients and are also associated with a variety of haemostatic abnormalities. Therefore, we analysed the relationships between free T4 (fT4) levels and Factor VII and VIII activities (FVIIc and FVIIc), D-Dimers (DDI) and Plasminogen Activator Inhibitor type 1 (PAI-1), in a group of 472 healthy patients referred for hyperlipidemia. Fourty patients were found to have primary hypothyroidism. A negative correlation was found in the whole study population between fT4 and DDI (p = 0.0001, r = -0.21) and the same results were found after exclusion of the patients with fT4 below the normal range (p = 0.0007, r = -0.17). In a multivariate regression analysis, the relationship between DDI and fT4 was independent of age, Body Mass Index (BMI), gender and total cholesterol. Less impressive correlation coefficients were found with FVIIc (r = -0.10), FVIIIc (r = -0.09) and PAI-1 (r = -0.09). These results suggest that fT4 may play a physiological role in the regulation of the haemostatic equilibrium in hyperlipidemic patients and that low levels of fT4 are associated with a hypercoagulable state.

Currently, technical methods to obtain precocious and reliable diagnosis of thyroid disorders are available for physicians. Therefore today, patients affected by mild hypo- or hyperthyroidism are more often diagnosed when they are still asymptomatic; these mild forms of thyroid disorder are known as subclinical hypo- and hyperthyroidism. In comparison with '80ties, over the last few years we have observed that patients come to endocrinological examination for subclinical forms of thyroid disorders (particularly for hypothyroidism) more frequently than for severe thyroid diseases. However, before to start a therapy, it is necessary for these patients to determine the causes of subclinical hypo- and hyperthyroidism. The main goals of therapy are to reduce the prevalence of cardiac arrhythmia and osteoporosis of patients with subclinical hyperthyroidism, and to slow down the course of arteriosclerotic disease (linked to hyperlipidemia and/or to hyperhomocysteinemia) of patients with subclinical hypothyroidism.

Urinary neopterin is increased in less than 20% of patients with breast carcinoma. Moderately increased neopterin concentrations are also known to accompany comorbid conditions commonly observed in patients with breast carcinoma, for example, diabetes mellitus or complications of atherosclerosis. In the present study, we evaluated the effect of the presence of comorbid conditions on urinary neopterin. A trend for higher neopterin concentrations was observed in patients with most of the comorbid conditions, but significantly higher neopterin was observed only in patients aged 70 years or older and in a heterogeneous group of patients with comorbidity other than diabetes mellitus, thyroid disorder, hyperlipidaemia, cardiac disorder or other malignancy. Significantly higher neopterin levels were noted in patients with two or more comorbid conditions. In conclusion, present data demonstrate an association between systemic immune activation reflected in increased urinary neopterin concentrations and age or presence of comorbid diseases in patients with breast carcinoma. A cumulative effect was observed with the presence of two or more comorbid conditions resulting in significantly increased urinary neopterin. These observations should be taken into account when interpreting the changes of parameters of systemic immune and inflammatory response in patients with breast carcinoma.

The objective of this study was to define the types of disease seen at the only endocrine clinic in Jamaica. The diagnoses of all patients attending the endocrinology clinic of the University Hospital of the West Indies over a 7-year period were analysed. Of the 1503 patients attending 263 weekly endocrinology clinics, 1251 patients had thyroid-related diseases, of which 684 patients had thyrotoxicosis and 233 patients had hypothyroidism. There were 17 pituitary tumours, eight cases of Cushing's syndrome and four of acromegaly. Cases of Sheehan's syndrome (n=11), hypopituitarism (n=17), hypoadrenalism (n=13), hypogonadism (n=9), primary hyperparathyroidism (n=3) and phaeochromocytoma (n=3) were rare. Thyroid disease was the most common diagnosis. New emerging endocrine disorders that are public health problems, such as obesity (n 21) and hyperlipidaemia (n=1), were rare. More traditional diseases, such as Sheehan's syndrome have become rare with improvements in obstetric care.
