The different types of serum lipoproteins, including apolipoprotein E phenotypes, were measured in 50 patients with xanthelasma. Half of them were found to be hyperlipemic. The normolipemic and hyperlipemic groups with xanthelasma were compared with two control groups (one a group of normolipemic patients and another a group of hyperlipemic patients without xanthelasma) selected as homogeneously as possible with regard to age, sex, degree of obesity, and hyperlipemic phenotype. The only significant differences found among the groups, regardless of the presence of hyperlipemia, were the increased levels of total and high-density lipoprotein phospholipids, and lower levels of apolipoprotein B, found in the group with xanthelasmas. The distribution of apolipoprotein E phenotypes was the same in both groups, with slight differences between the normolipemic and hyperlipemic groups. Patients with xanthelasmas showed slight deviations in the metabolism of lipoproteins that require further clarification.

The prevalence rates of xanthelasma and corneal arcus were computed for normolipidemic and dyslipoproteinemic participants in the Lipid Research Clinics population surveys. The prevalence of both xanthelasma and corneal arcus increased with age, was highest in persons with type II phenotype, and usually low in those with type IV phenotype. The relative effects of age and use of gonadal hormones were different in the two lesions. Both xanthelasma and corneal arcus were associated with increased levels of plasma cholesterol and low-density lipoprotein cholesterol (LDL-C), especially in young males. In general, persons with either lesion had increased odds of having type IIa dyslipoproteinemia but decreased odds of having type IV. Xanthelasma and corneal arcus were highly associated with each other, especially in young people. There was no consistent univariate association of xanthelasma and corneal arcus with smoking, alcohol consumption, blood pressure, obesity, sedentary lifestyle, family history of ischemic heart disease, or glucose and uric acid plasma concentrations. Adjusted odds ratios for ischemic heart disease in participants with xanthelasma and corneal arcus were generally increased, except in older female nonusers of gonadal hormones, in whom they were significantly decreased. Neither xanthelasma nor corneal arcus showed a consistent association with manifestations of peripheral arterial disease. Thus the clinical findings of xanthelasma or corneal arcus, especially in young people, seem to identify persons with plasma lipoprotein abnormalities.

The clinical findings in 63 patients with xanthomas were analysed. Among them 5 had xanthelasmas and normal lipids. The largest group (37) consisted of females with xanthelasmas and heterozygotic form of hyperlipoproteinemia (HLP) type II. In this group HDL cholesterol values (1,5 mmol/l) were normal and ischemic heart disease (IHD) was rare. However, in 14 males HDL values (1,1 mml/l) were low while IHD was common. Cholesterol deposits in the folds of the palm (xanthochtomia striata palmaris), tuberous xanthoma and peripheral artery changes were characteristical findings for all three patients with HLP type III. In patients with HLP type IV and eruptive xanthomas, obesity was common finding (4/4) and disturbed glycoregulation (2/4) and triglyceride values were very high (X = 61,1 mmol/l).

In a retrospective study about 600 hyperlipoproteinaemic patients (390 men and 210 women, mean age 47), xanthelasma palpebrarum was infrequent (25 cases or 4.16 p. 100), since it was only at the third rank of chronic extra-vascular lipid deposits after arcus corneus and tendineous xanthomas. It was twice as frequent in men (5.12 p. 100) as in women (2.38 p. 100) and of regularly increasing occurrence until the sixth decade. Among the atherosclerotic risk factors, only obesity was significantly associated. The existence of atherosclerotic diseases was observed more frequently in patients with xanthelasma palpebrarum (40 p. 100) than in total hyperlipoproteinaemic population (28 p. 100). In a second retrospective study concerning 29 patients (15 men and 14 women, mean age 50), selected from the only presence of one or several xanthelasma palpebrarum, a lipoproteinaemic abnormality was observed in 27 cases (93 p. 100): 23 patients (71 p. 100) were hyperlipoproteinaemic (type IIa, IIb or IV) and in 4 out of 6 normolipidemic patients we observed an abnormal lipoprotein cholesterol distribution (LDL + VLDL cholesterol increase and HDL cholesterol decrease). In this group, we observed in nine patients (31 p. 100) unknown atherosclerotic diseases and tendineous xanthomas in other nine patients (31 p. 100).

In recent years, the association between hyperlipidemia and the development of arteriosclerosis has been addressed in several studies. Rabbit models of hypertriglyceridemia (TGH) and postprandial hypertriglyceridemia (PHT) have been developed at the authors' institute. TGH rabbits manifest pathology similar to that of humans with TGH, such as xanthoma, in addition to atherosclerosis of arterioles. Furthermore, PHT rabbits show visceral obesity, insulin resistance, and impaired glucose tolerance, with pathologic features similar to those of the metabolic syndrome assumed to be the cause of human ischemic heart disease. This study was designed to investigate the histopathologic features of TGH and PHT rabbits. TGH rabbits showed advanced aortic atherosclerosis, accompanied by intimal thickening of coronary and renal arteries, fatty liver changes, and xanthoma. PHT rabbits demonstrated aortic intimal thickening and hepatic fatty degeneration. The results of this study suggest that TGH and PHT rabbits are useful animal models for studying human hyperlipidemia and metabolic syndrome and the cardiovascular diseases that result from these conditions.

Coronary artery disease (CAD) is rapidly increasing in prevalence across the world and particularly in south Asians at a relatively younger age. As atherosclerosis starts in early childhood, the process of risk evaluation must start quite early. The present review addresses the issue of cutaneous markers associated with atherosclerosis, and the strengths and weaknesses of the markers in identifying early coronary atherosclerosis. A diligent search for such clinical markers, namely xanthelasma, xanthoma, arcus juvenilis, acanthosis nigricans, skin tags, ear lobe crease, nicotine stains, premature graying in smokers, hyperpigmented hands in betel quid sellers, central obesity, and signs of peripheral vascular disease may prove to be a rewarding exercise in identifying asymptomatic CAD in high risk individuals.

Psoriasis is currently considered a multifactorial disease, which can coexist with many somatic and psychological disorders. We present the case of a 50-year-old woman referred to our department due to erythroderma with concomitant peculiar violaceous, polycyclic lesions most likely induced by medications. Past medical history revealed numerous systemic disorders, including metabolic syndrome, hypertension, cardiac insufficiency, obesity, and depression. Additional examinations and consultations demonstrated dyslipidemia, xanthelasma, incomplete block of the right branch of His bundle, thyreocardiac syndrome, benign adrenal tumor, and delusions. Recently, psoriasis has been intensively studied. We present the case in which erythroderma was most likely triggered by acitretin combined with ceftriaxone. Treatment of many diseases and psychiatric disturbances coexisting with psoriasis is extremely difficult and requires cooperation of various specialists.

Some external features serve as a warning sign for accelerated atherosclerosis. Their early recognition may help in early detection and primary prevention/preemptive treatment of coronary artery disease (CAD). A 35-year-old nonsmoker, nonalcoholic, nonhypertensive, nondiabetic male presented with chest pain and was diagnosed to have acute ST elevation inferior wall myocardial infarction. His father had died of CAD at 40 years of age. The patient had bilateral extensive xanthelasma and gynoid obesity. His mother and younger brother also had evidence of bilateral xanthelasma; both turned out to be dyslipidemic - the younger brother qualifying for therapeutic intervention for dyslipidemia at 26 years of age. This case highlights the importance of familial xanthelasma as a cutaneous marker for underlying dyslipidemia and accelerated atherosclerosis in the young.

Currently, the familial hypercholesterolemia (FH) rises the interest. The reason is that this genetic disorder is targeted by newly emerged and highly effective hypolipidemic agents, PCSK-9 inhibitors, lomitapid and mipomersen. Present paper discusses 2 patient study groups, before 50 years and nowadays. Although direct statistical analysis is impossible some changes in clinical features of FH might be found over the course of the time. In fact, the basic FH characteristic has not changed dramatically. Severe isolated hypercholesterolemia with total cholesterol 9-10 mmol/l, LDL-cholesterol 7-8 mmol/l and normal values of triglycerides dominates in laboratory analysis. Interestingly, the values of triglycerides increase and almost reach the pathological range in comparison to the values from the period 50 years ago. The values of HDL-cholesterol are normal. Manifestation of CHD in male patients over 40 years of age and in female patients over 50 years of age is not exceptional (rarely occur cases of myocardial infarction in third decade of age). Typical clinical manifestation of FH is xanthomatosis. The early detection and aggressive treatment in FH patients cause that xanthoma tendinosum, xanthelesma and arcus lipoides are less frequent as decades ago. Obesity, diabetes mellitus (DM) and hypertension do not belong to typical clinical sign of FH.

Background: Xanthelasma palpebrarum refers to xanthomas that occur more often near the inner canthus of the eyelid. Periorbital hyperpigmentation presents as a dark area surrounding the eyelids. Objective: In the present study, the authors examined the prevalence and the associated factors of periorbital hyperpigmentation among patients with xanthelasma. Methods: One hundred and fourteen patients with xanthelasma palpebrarum were examined for the presence of dark circles. Detailed questionnaires regarding the history of diabetes, hypothyroidism, smoking status, and weight were completed by all patients. They were also tested for serum lipids (cholesterol, low-density lipoprotein, triglycerides, apolipoprotein A and apolipoprotein B). Results: From the 114 patients with xanthelasma, 94 (82.4%) were diagnosed with periorbital hyperpigmentation. At the time of the survey, 46 patients were smokers (48.9%), 23 of them had hypothyroidism (24.4%), and 16 patients were obese (17%). Only four patients had a history of diabetes. Cholesterol levels were elevated in 65 patients (69.1%). In 52 patients (55.3%), low-density lipoprotein was increased and in 51 patients (54.2%), both cholesterol and low-density lipoprotein were elevated. Apolipoprotein A was increased in 35 patients (37.2%), whereas apolipoprotein B was increased in 23 patients (24.4%). Conclusions: This study showed that a significant number of patients with xanthelasma exhibited periorbital hyperpigmentation. Smoking, obesity, and hyperlipidemia were observed in these patients.
