Twenty-one asymptomatic patients presenting isolated elevations of gamma-glutamyltranspeptidase (GGT) were studied over the previous 10 years with all the findings being accidental. No other analytical alterations were demonstrated. Ingestion of alcohol, drugs or another type of toxic substance, diabetes, neurologic disease or neoplasm were discarded. Echography of the liver and the biliary tract was normal. In the first nine patients studied, liver biopsy was performed being normal or with minimum unspecific alterations. In two patients endoscopic retrograde cholangiography was carried out with no alterations being observed. Lipid study was performed in all the patients with alpha hypolipoproteinemia being found in 15 patients, compensated type II lipid profile in 5 and a normal lipid profile in one. To the author's knowledge there have been no reports of this lipid disorder causing elevations in GGT. However, on being the only abnormality found in these patients the authors believe that this may be the cause although the mechanism is unknown.

Atherosclerosis is a disease with a chronic-progressive course. We report on the statistic prevalence of vascular lesions in 1,500 asymptomatic patients with vascular diseases examined with Computed Tomography (CT) for different reasons. The aortoiliac arterial district was involved in 934/1,500 patients (62.3%), with simple or calcified plaques, thrombosis or dilatations. We investigated the involvement of other arterial vessels (47%) whenever feasible (57.7% of cases). The aorta was thrombosed in 107 patients (2.8%) and the thrombus associated with a calcification and a dilated vessel in 45 of them (42.1%). The aorta or the iliac arteries were enlarged in 62 patients (4.1%) and arterial diameter exceeded 4 cm in 20 patients (1.3%). Finally, the statistical significance was analyzed considering risk factors-i.e., smoking, arterial hypertension, diabetes and hypolipoproteinemia. All the patients with 2 or more risk factors had positive CT findings; the prevalence was 75% in cigarette smokers, 83% in hypertensive, 81.3% in dislipidemic and 93.5% in diabetic patients. These data demonstrate that, in agreement with international literature reports, it is possible to single out the groups of patients that, because of their age, risk factors and sex, should be considered for color Doppler screening programs and the selected cases to be submitted to CT.

LDs (lipid droplets) carrying TAG (triacylglycerol) and cholesteryl esters are emerging as dynamic cellular organelles that are generated in nearly every cell. They play a key role in lipid and membrane homoeostasis. Abnormal LD dynamics are associated with the pathophysiology of many metabolic diseases, such as obesity, diabetes, atherosclerosis, fatty liver and even cancer. Chylomicrons, stable droplets also consisting of TAG and cholesterol are generated in the intestinal epithelium to transport exogenous (dietary) lipids after meals from the small intestine to tissues for degradation. Defective chylomicron formation is responsible for inherited lipoprotein deficiencies, including abetalipoproteinaemia, hypobetalipoproteinaemia and chylomicron retention disease. These are disorders sharing characteristics such as fat malabsorption, low levels of circulating lipids and fat-soluble vitamins, failure to thrive in early childhood, ataxic neuropathy and visual impairment. Thus understanding the molecular mechanisms governing the dynamics of LDs and chylomicrons, namely, their biogenesis, growth, maintenance and degradation, will not only clarify their molecular role, but might also provide additional indications to treatment of metabolic diseases. In this review, we highlight the role of two small GTPases [ARFRP1 (ADP-ribosylation factor related protein 1) and ARL1 (ADP-ribosylation factor-like 1)] and their downstream targets acting on the trans-Golgi (Golgins and Rab proteins) on LD and chylomicron formation.
