Hypertriglyceridemia has frequently been found both in subjects with AIDS and in asymptomatic HIV-positive ones. In order to evaluate the importance of hyperlipemia as an index of the clinical evolution of HIV infection, the levels of triglycerides, total cholesterol and CD4 lymphocytes were determined over a period of 2 years in 8 haemophiliacs with AIDS, 13 asymptomatic HIV-positive and 45 HIV-negative haemophiliacs attending the Operative Unit of Coagulation Disorders of the University of Pisa. The mean concentration of triglycerides and incidence of hypertriglyceridemia were significantly higher in haemophiliacs with AIDS, compared with HIV-negative subjects (p<0.0001), while the triglycerides values of asymptomatic HIV-positives fell between those of the other groups. Cholesterol levels were lower in HIV-positive haemophiliacs and in those with AIDS compared with HIV-negatives. No correlation was found between triglyceride levels and those of CD4 lymphocytes.

Background: Stroke mainly affects the older population, although it has also been reported in younger patients. In this study, we focused on patients 65 years of age or younger with stroke. Methods: The files of three patient populations were studied: 93 patients aged 65 years or younger with stroke (group A), 93 patients older than 65 with stroke (group B), and 604 patients without stroke representing the general population of patients admitted to our service during January 2000 (group C). We reviewed the patient files and compared patient characteristics, epidemiological features, clinical picture,imaging findings, and coagulation tests. Results: Overall, 318 patients were studied. The mean age of group A was 55 years compared to 77 years in group B and 71 years in group C. In both stroke groups (A and B), the male: female ratio was 2:1, in contrast with a balanced ratio in group C. Most of the patients in group A (63%) were of Sephardic origin compared to 39% in group B (P=0.002) and 30% in group C. The clinical picture in both stroke groups (A and B) was similar. The risk factor smoking was reported by 45% in group A and by only 29% in group B (P=0.034). Hypertension, diabetes mellitus, and hyperlipidemia were evenly prevalent in both stroke groups. The coagulation system was studied in the "young" patients (group A): hyperhomocysteinemia was found in 37%, high titers of anticardiolipin antibodies in 35%, low levels of antithrombin III in 13%, protein C deficiency in 5%, and activated protein C resistance (APCR) in 4%. Overall, 49% of the patients from group A were found to have coagulation abnormalities. Conclusions: We found in our study that the younger patient with stroke tends to be a Sephardic male with the classical risk factors as well as a history of smoking and coagulopathy. These findings suggest strict medical supervision and primary prophylaxis. This work also lays the basis for a prospective, interventional trial with younger patients.

Cardiovascular disease is the leading cause of morbidity and mortality following renal transplantation. Because many renal transplant recipients die with functioning grafts, deaths resulting from cardiovascular disease have became an increasingly important cause of graft loss, particularly after the first post-transplantation year. Moreover, a contribution of some cardiovascular risk factors to renal allograft dysfunction has been demonstrated. A number of observational studies suggest that cardiovascular disease is more common in renal transplant patients than in the general population. The excessive risk for cardiovascular disease is related to a high prevalence and accumulation of atherogenic risk factors before and after transplantation. Hypertension, post-transplantation diabetes and hyperlipidemia are well-recognized risk factors for the development of cardiovascular events after renal transplantation and are strongly associated with immunosuppressive therapy. Progressive renal dysfunction may also influence the risk of cardiovascular complications after renal transplantation. The elevated risk may also be caused by non- traditional risk factors such as anaemia, adhesion molecules, hyperhomocysteinemia, microinflammatory state, abnormal coagulation and oxidative stress. To prevent post-transplantation cardiovascular disease it is crucial to define the etiological risk factors. Some risk factors can be modified, and for some of these, there is strong evidence from studies in the general population that intervention improves survival. Given the significant morbidity and mortality of cardiovascular disease in renal transplant recipients, aggressive treatment intervention for potentially modifiable factors are strongly advocated after transplantation. In addition to treatment intervention, risk management should also involve tailoring the immunosuppressive regimen to minimize both direct and indirect cardiovascular risks. In this article we attempted to review and quantify the post-transplant risk factors for cardiovascular disease as well as offer suggestions on optimizing the therapy or treatment strategies to minimize the risk of cardiovascular complications in renal transplant patients. Reduction of cardiovascular morbidity and mortality can improve not only the life expectancy and quality of life of the transplant recipients but also their graft function and survival.

Intrauterine growth restriction (IUGR) and preeclampsia differ in their association with maternal disease but share a similar placental pathology. Moreover, mothers who have had pregnancies complicated by preeclampsia or IUGR are at elevated later-life cardiovascular risk. Why, then, do some women develop IUGR and others develop preeclampsia? In this clinical opinion, based on a review of the literature, we hypothesize that both women experiencing preeclampsia and IUGR enter pregnancy with some degree of endothelial dysfunction, a lesion that predisposes to shallow placentation. In our opinion, preeclampsia develops when abnormal placentation, through the mediator of elevated circulating cytokines, interacts with maternal metabolic syndrome, comprised of adiposity, insulin resistance/hyperglycemia, hyperlipidemia, and coagulopathy. IUGR develops in the absence of antenatal metabolic syndrome. Among these women, the baby is affected by shallow placentation but the mother does not develop clinically apparent disease. This conceptualization provides a testable framework for future etiologic studies of preeclampsia and IUGR.

We report a patient with carnitine palmitoyltransferase I (CPT I) deficiency, who presented with acute encephalopathy at 6 months of age. This was precipitated by an episode of gastroenteritis. No hypoglycaemia was documented, but there was hepatomegaly; blood tests revealed raised transaminases, a coagulopathy and severe hypertriglyceridaemia (48.8 mmol/L) and hypercholesterolaemia (9.5 mmol/L). The hyperlipidaemia resolved within 3 days of treatment and did not recur. At 2 years of age, the patient's liver function, growth and development are all normal. Hyperlipidaemia has been reported during acute illness in previous patients with CPT I deficiency but it is not a well-recognized feature; it should alert metabolic specialists to this potential diagnosis.

Endothelial dysfunction, including impaired vasomotor disturbance, abnormal coagulation, and increased vascular proliferation, is closely associated with the development of atherosclerosis and precedes the clinical manifestations of atherosclerosis. The impairment of endothelium-dependent vasodilation, which is chiefly attributed to decreased endothelial nitric oxide (NO) bioavailability, represents the functional characteristic of endothelial dysfunction and a early key step in the occurrence of atherosclerotic complications. An impairment of endothelial vasodilation is attributed to decreased NO production, deficiency of substrate or cofactor availability, and increased NO inactivation, and is not confined to a certain artery such as the coronary artery, but rather represents a systemic disorder that also affects peripheral vascular beds. Noninvasive endothelial function tests using extremities are a new popular method for the detection of endothelial NO bioavailability. The assessment of endothelial function detected before established atherosclerosis may be a more important risk factor to predict future atherosclerotic diseases compared with conventional risk factors such as hypertension and hyperlipidemia.

A 41-year-old woman presented with acute angina in the emergency unit. Additionally, she reported pain in both legs and a weight loss of 5 kilograms within the last 10 days. ECG revealed an acute anterior myocardial infarction. However, immediate coronary angiography showed open arteries with minimal arteriosclerosis. A characteristic rise of cardiac enzymes together with an akinesis of the anterior wall and an adjacent mural thrombus was highly suggestive of a transient coronary thrombosis. Further investigations showed occlusion of multiple arteries in both legs and a splenic infarct. Although there was a typical risk profile including smoking, hyperlipidemia and regular estrogen medication, a further work-up was started. Urin analysis was decisive for the presence of proteinuria and a severe nephrotic syndrome. The definite diagnosis was made by direct biopsy of the kidney that revealed the characteristic findings of a minimal change glomerulopathy. Rapid remission could be induced by high-dose oral steroids. During routine work-up of coronary syndromes, especially in those with normal coronaries, rare but treatable causes of myocardial infarction and coagulopathy have to be thought of and should carefully be excluded.

The congenital nephrotic syndrome (NS) in infancy and childhood is an important entity but combination with acyanotic congenital heart disease is uncommon. Anesthesia in such cases is challenging because of associated problems like hypo-protienemia, anti-thrombin III deficiency, edema, hyperlipidemia, coagulopathy, cardiomyopathy, immunodeficiency, increased lung water etc. We describe anesthetic management of a patient with childhood NS and sinus venosus atrial septal defect (ASD) undergoing open heart surgery. We also suggest guidelines for safe conduct of anesthesia and CPB in such patients.

Blood stasis is one of the important pathological concepts in Korean medicine. We analyzed the Korean studies concerning blood stasis. We searched for articles in eight electronic databases from their inception to September, 2014. We included reviews, clinical studies, and preclinical studies that had studied blood stasis and excluded articles in which blood stasis was not mentioned or in which the original authors had not explained blood stasis. Of 211 total included studies, 19 were reviews, 52 were clinical studies, and 140 were preclinical articles. "Stagnant blood within the body" was the most frequently mentioned phrase of the traditional concept of blood stasis. Traumatic injury was the most frequently studied disease/condition in the clinical studies. In the preclinical studies, coagulopathy was studied most frequently, followed by hyperviscosity, hyperlipidemia, inflammation, neoplasm, ischemic brain injury, and atherosclerosis. Hyeolbuchukeo-tang and Angelicae Gigantis Radix were the most frequent formula and single herb, respectively, used in the blood stasis researches. The results showed that blood stasis was mainly recognized as disorder of circulation and many studies showed the effectiveness of activating blood circulating herbs for diseases and pathologies such as traumatic injury or coagulopathy. Further studies are needed in the pathologic mechanisms and various diseases of blood stasis.

Polyunsaturated fatty acids such as omega-3 eicosapentaenoic acid and omega-6 docosahexaenoic acid, found in over-the-counter fish oil supplements, are often consumed for their beneficial, prophylactic, anti-inflammatory effects. Although the mechanisms of action are not fully known, a diet rich in polyunsaturated fats may reduce the risk of hyperlipidemia, atherosclerosis, high low-density lipoprotein cholesterol levels, hypertension, and inflammatory diseases. Masked by its many benefits, the risks of omega-3 fatty acid supplementation are often underappreciated, particularly its ability to inhibit platelet aggregation and promote bleeding in patients taking anticoagulant medications. The following details the clinical case of an elderly patient taking warfarin and fish oil supplementation whose warfarin-induced coagulopathy could not be reversed after suffering blunt head trauma.
