The main goal of hypercholesterolemia management for coronary prevention is to reduce serum low-density lipoprotein cholesterol (LDL-C) levels. D-003 is a mixture of high molecular weight aliphatic acids purified from sugarcane wax, while policosanol is a cholesterol-lowering drug purified from the same source, consisting in a mixture of higher aliphatic alcohols. No previous comparative study of both drugs in humans has been reported. This randomized, double-blind study compares the efficacy and tolerability of D-003 and policosanol (5 and 10 mg/day) in patients with type II hypercholesterolemia...

The term sensitive skin has been used to describe a clinical phenomenon of skin hyperreactivity induced after exposure to different external factors. The diagnosis is mainly based on patient's self-assessment because of the lack of objective clinical signs of the disease. The aim of this study was to investigate psychiatric factors in patients with sensitive skin and to estimate the possible need for psychological intervention to these patients. Thirty-seven patients with sensitive skin and 38 individuals with nonsensitive skin were studied...

Mycotic scalp infection caused by Microsporum canis is the most dominant cause of tinea capitis in Greece. Griseofulvin has been the gold standard for the treatment of tinea capitis, but it is unavailable in our country. In this study, we evaluated 111 children with M. canis tinea capitis that were treated with itraconazole. Eighty-one of them were treated with itraconazole capsule pulse therapy (group A) and 30 (group B) were treated with oral suspension administered in continuous regimen. Twenty-one patients, all from group A, were lost to follow-up, probably due to the length of this regimen...

Otitis media with effusion (OME) is a common pediatric disease and there is great controversy concerning its management. Mechanical, medical and surgical treatments have not proven adequate in resolving the disease and serve mainly to manage complications. Leukotriene inhibitors are new drugs that have been approved recently for the treatment of asthma in children. The aim of this study was to evaluate the impact of leukotriene inhibitor therapy for asthma on the clinical course of OME in children with co-existing disease...

Pigment epithelium-derived factor (PEDF) is a natural extracellular component of the retina with neuronal differentiating activity. Recently, decreased levels of PEDF in the mammalian eye have been shown to participate in the pathogenesis of diabetic retinopathy In addition, advanced glycation end products (AGEs), senescent macroprotein derivatives that form at an accelerated rate under diabetes, have also been implicated in the development and progression of diabetic retinopathy. However the role of AGEs in decreased levels of PEDF in the eye remains to be elucidated...

Advanced glycation end products (AGEs), the senescent macroprotein derivatives that form in increased amounts in diabetes, have been implicated in the pathogenesis of accelerated atherosclerosis. There is a growing body of evidence that CD40-CD40 ligand (CD40L) interaction also plays an important role in atherogenesis. However, the effects of AGEs on CD40-CD40L signaling in endothelial cells (ECs) remain to be elucidated. In this study, we investigated (i) whether injection of AGE-proteins to normal rats stimulates CD40L expression on circulating platelets and (ii) whether AGEs up-regulate CD40 mRNA levels in cultured ECs...

We have previously shown that azelnidipine, a long-acting dihydropyridine-based calcium antagonist (DHP), inhibited tumor necrosis factor-alpha-induced endothelial cell (EC) activation through its antioxidative properties. However whether azelnidipine could also block the angiotensin II (Ang II)-signaling in ECs remains to be elucidated. Since Ang II-type 1 receptor interaction could contribute to exacerbation of diabetic retinopathy by downregulating pigment epithelium-derived factor (PEDF) gene expression in ECs, we examined here whether azelnidipine inhibited the Ang II-induced reactive oxygen species (ROS) generation and subsequent PEDF gene suppression in microvascular ECs...

Juzen-Taiho-To (JTT) is a Japanese herbal medicine that has been administered mainly to patients weakened by long illness. Currently, it has also been used for cancer patients and showed antitumor effects that have been reported as phagocytosis enhancement, cytokine induction and antibody production. In this study, we examined the effect of oral administration of JTT in mice on the immunological restoration of the liver, especially focused on natural killer (NK) T-cell induction. Mice were grouped to receive JTT or placebo orally for a period of 1, 3 and 7 days...

Benign prostatic hyperplasia (BPH) is a nonmalignant growth of prostate leading to difficulty in urinating. Drug therapy, phytotherapy included, is frequently used to treat BPH. D-004 is a lipid extract from Roystonea regia fruits, and previous studies have shown that oral treatment with D-004 for 14 days prevented prostate hyperplasia (PH) induced by testosterone in rats. No information is available, however; about the effects of D-004 in reverting already established PH. This study investigated whether D-004 could improve PH after oral dosing with testosterone in rats...

The mevalonate pathway is relevant in bone cells. Statins inhibit 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the key enzyme of this route, stimulating osteoblast differentiation and activity. Pravastatin increases bone formation markers in postmenopausal women and bone density in diabetics. D-003 is a mixture of high-molecular-weight acids purified from sugarcane wax which inhibits cholesterol biosynthesis through HMG-CoA reductase regulation, preventing bone loss in osteoporosis induced with ovariectomy and prednisolone in rats...

Benzodiazepine-like compounds (BZDs), either taken with the diet or synthesized by intestinal bacterial flora, may represent a precipitating factor for hepatic encephalopathy (HE) in cirrhotic patients. We evaluated whether a diet and/or treatment with rifaximin or lactulose can reduce serum concentrations of BZDs in 18 cirrhotic patients without HE. Patients were given a standard diet for 7 days to keep the dietary intake of BZDs constant and were then randomized to a 7-day treatment with rifaximin 1,200 mg/day, lactulose 10-20 g three times daily, or placebo...

Insulin resistance is one of the determinants of postprandial hyperglycemia. Acarbose is an alpha-glucosidase inhibitor that delays the absorption of carbohydrates from the small intestine, thereby suppressing postprandial hyperglycemia. Recently, acarbose has been found to reduce the incidence of cardiovascular disease (CVD) in patients with diabetes. These observations suggest that intervention of postprandial hyperglycemia with acarbose is a promising strategy for the prevention of CVD in diabetic patients...

Tacrolimus is an immunomodulatory agent that inhibits the activation and maturation of T-cells and blocks transcriptional activation of several cytokine genes. It also interferes with the function of Langerhans cells, basophil cells and mast cells. Recent studies have demonstrated the efficacy of topical tacrolimus in inflammatory skin disorders. Our objective was to assess the efficacy of topical treatment with tacrolimus ointment 0.1% in patients with psoriasis on the anogenital region and the face. Included in the study were 10 patients with a long-standing history of genital and facial psoriasis, partially controlled with periodic use of topical corticosteroids...
