Acquired hemophilia A (AHA) is a rare coagulation disorder due to the development of an autoantibody against and inhibitor of coagulation factor VIII. It has been reported that immunosuppressive therapy with corticosteroids, cyclophosphamide, azathioprine and vincristine are effective to decrease this inhibitor. When corticosteroids and cytotoxic drugs are ineffective, cyclosporine A (CyA) may be effective as a second-line salvage therapy. Except for postpartum conditions, AHA usually occurs in elderly patients who are often already suffering from diabetes mellitus, ischemic heart disease and/or hyperlipidemia. However, immunosuppressive and cytotoxic drugs may have adverse effects on these patients. We report on a 66-year-old man who developed AHA after colon cancer resection (factor VIII inhibitor: 61 Bethesda units/ml, aPTT : 97.9 s). Since he already had both diabetes mellitus and ischemic heart disease, we abandoned treatment with corticosteroids and oral cyclophosphamide was started, but was switched to CyA because of leukopenia. Within 3 months of starting the CyA treatment, aPTT levels returned to normal and 4 further months were required for complete eradication of the inhibitor. This case revealed that CyA is as effective as corticosteroids for AHA. For patients with AHA who have unfavorable complications due to corticosteroids and cytotoxic drugs, CyA could be a potential first-line drug.

A consensus view of soyabean phyto-oestrogens in clinical interventions in post-menopausal women is presented that is based on data from the EU-funded project Phytohealth. The phyto-oestrogens, primarily genistein and daidzein, were given as soyabean-protein isolates, whole-soyabean foods or extracts, supplements or pure compounds. A comprehensive literature search was conducted with well-defined inclusion or exclusion criteria. For areas for which substantial research exists only placebo-controlled double-blind randomised controlled trials (RCT) conducted on healthy post-menopausal women were included. For emerging areas all available human studies in post-menopausal women were reviewed. In order to make cross comparisons between studies the doses of isoflavones were calculated as aglycone equivalents. There is a suggestion, but no conclusive evidence, that isoflavones from the sources studied so far have a beneficial effect on bone health. The consumption of whole-soyabean foods and soyabean-protein isolates has some beneficial effects on lipid markers of cardiovascular risk. The consumption of isolated isoflavones does not affect blood lipid levels or blood pressure, although it may improve endothelial function. For menopausal symptoms there is currently limited evidence that soyabean-protein isolates, soyabean foods or red-clover (Trifolium pratense L.) extract are effective but soyabean isoflavone extracts may be effective in reducing hot flushes. There are too few RCT studies to reach conclusions on the effects of isoflavones on breast cancer, colon cancer, diabetes or cognitive function. The health benefits of soyabean phyto-oestrogens in healthy post-menopausal women are subtle and even some well-designed studies do not show protective effects. Future studies should focus on high-risk post-menopausal women, especially in the areas of diabetes, CVD, breast cancer and bone health.

We hypothesize that the peroxisome proliferator-activated receptor-gamma (PPARgamma) is associated with colorectal cancer given its association with insulin, diabetes, obesity, and inflammation. In this study, we evaluated the association between colorectal cancer and specific tumor mutations and the Pro12Ala (P12A) PPARgamma polymorphism. We also evaluated interactions between the PPARgamma gene and other insulin-related genes and use of aspirin and non-steroidal anti-inflammatory drug use. Data were available from 1,577 cases of colon cancer that were matched to 1,971 population-based controls and 794 cases of rectal cancer that were matched to 1,001 population-based controls. Colon tumors from the case subjects were evaluated for p53 and Ki-ras mutations and microsatellite instability (MSI). Insulin-related genes evaluated were the Bsm1, polyA, and Fok1 polymorphisms of the VDR gene; the G972R IRS1 polymorphism; the G1057D IRS2 polymorphism; the 19CA repeat polymorphism of the IGF1 gene; and the -200A>C IGFBP3 polymorphism. The odds ratio (OR) between the PA/AA genotypes and proximal tumors was 0.83 (95% CI: 0.69-1.01); for distal tumors was 1.00 (95% CI: 0.83-1.21); and for rectal tumors was 1.04 (95% CI: 0.86-1.25). Evaluation of specific types of tumor mutations showed that colon cancer cases with the PA or AA genotypes were less likely to have p53 tumor mutations (OR 0.78; 95% CI: 0.62-0.99), specifically transition mutations (OR 0.74; 95% CI: 0.56-0.97). Colon cancer cases also were less likely to have a tumor with MSI if they had the PA or AA PPARgamma genotype (OR 0.68; 95% CI: 0.47-0.98); differences in Ki-ras mutations were not seen in colon tumors by PPARgamma genotype. Those who did not take ibuprofen-type drugs and had the PA or AA genotypes were at a significantly greater risk of rectal cancer (OR 2.11; 95% CI: 1.52-2.92; p interaction 0.03) than people with the PP genotype regardless of ibuprofen-type drug use. There was a significant interaction between the -200A>C IGFBP3 polymorphism and the Pro12Ala PPARgamma polymorphism and risk of colon cancer (p for interaction = 0.02) with individuals being at significantly lower risk if they had both the CC IGFBP3 genotype and the PA/AA PPARgamma genotype. For rectal cancer there was a significant interaction between the Bsm1/polyA polymorphisms (p = 0.001) of the VDR gene and the PA/AA Pro12Ala PPARgamma polymorphism with the highest risk group being those with both the PA/AA Pro12Ala PPARgamma and the BB/SS VDR genotypes. These data suggest that PPARgamma may be associated with many aspects of colorectal cancer including insulin- and inflammation-related mechanisms.

The sun is our most important source of vitamin D. Exposure to solaria, in sub-erythemogenic doses, also gives large amounts of this vitamin. The ultraviolet radiation in these sources converts 7-dihydrocholesterol to previtamin D3 in the skin. Furthermore, heat isomerization to vitamin D3 takes place, then transport to the liver and hydroxylation to calcidiol, which is transported to the kidneys and hydroxylated to the active hormone calcitriol. The vitamin D3 status of the body is supposed to be reliably imaged by calcidiol measurements. Calcidiol levels above 12.5 nmol/l prevent rickets and osteomalacia, but optimal levels are probably higher, in the range 100-250 nmol/l. A daily food intake of 100-200 microg vitamin D3 (50-100 g cod-liver oil), or a weekly exposure to two minimal erythemal doses of ultraviolet radiation (20 to 40 minutes whole body exposure to midday midsummer sun in Oslo, Norway), will give this level. An adequate supply of vitamin D3 seems to reduce the incidence rates or improve the prognosis of several cancer forms, including prostate, breast and colon cancer, as well as of lymphomas. Several other diseases are related to a low vitamin D3 status: heart diseases, multiple sclerosis, diabetes, and arthritis. The action mechanisms of vitamin D are thought to be mainly related to its known cell-differentiating and immuno-modulating effects. Even though most of the 250 annual death cases from skin cancer in Norway are caused by sun exposure, we should, in view of the health effects of ultraviolet radiation, consider modifying our restrictive attitude towards sun exposure and use of solaria.

The role of obesity in diabetes mellitus, hyperlipidemia, colon cancer, sudden death and other cardiovascular diseases has confirmed in many recent research studies. In present study, it is hypothesized that obesity can serve as an independent risk factor for the decreased activities of cytoprotective antioxidants in humans and for the associated systemic oxidative stress. 150 age matched, female subjects with no history of smoking or biochemical evidence of diabetes mellitus, hypertension, hyperlipidemia, renal or liver disease or cancer were included in the study and were divided into different grades of obesity according to their body mass index (BMI). Hemoglobin and erythrocyte glutathione (GSH) concentrations were measured for each subject. The study suggests that increase BMI was found to be associated with a significant decrease in erythrocyte glutathione concentration. From these observations it is concluded that obesity even in the absence of smoking, diabetes mellitus, hyperlipidemia, renal or liver diseases can decrease the activities of body's protective antioxidants, and can enhance the systemic oxidative stress and should therefore receive the same attention as obesity with complications.

Several clinical cohort and case-control studies have suggested a link between diabetes and colon cancer. Otsuka Long-Evans Tokushima Fat (OLETF) rats spontaneously develop type 2 diabetes mellitus and Long-Evans Tokushima Otsuka (LETO) rats are non-diabetic. The relationship between type 2 diabetes mellitus and colon cancer was examined in these rats. The carcinogen 1,2-dimethylhydrazine was administered subcutaneously once weekly for 10 weeks, and the animals were killed and necropsied in week 29. All OLETF rats and 80% of the LETO rats developed cancer. The number of colon cancers per rat was significantly greater in the diabetic than in the non-diabetic rats. Although the tumours tended to be larger in diabetic rats, the difference was not statistically significant. No significant differences were observed in the depth of invasion or histological type of cancer in the two groups. Type 2 diabetes mellitus may enhance the generation and growth of colon cancer.

Initially, it was hoped that resistant starches (ie, starches that enter the colon) would have clear advantages in the reduction of colon cancer risk and possibly the treatment of ulcerative colitis. Recent studies have confirmed the ability of resistant starch to increase fecal bulk, to increase the molar ratio of butyrate in relation to other short-chain fatty acids, and to dilute fecal bile acids. However, reduction in fecal ammonia, phenols, and N-nitroso compounds have not been achieved. At this point the picture from the standpoint of colon cancer risk reduction is not clear. Nevertheless, there is a fraction of what has been termed resistant starch (RS1), which enters the colon and acts as slowly digested, or lente, carbohydrate. Foods in this class are low glycemic index and have been shown to reduce the risk of chronic disease. They have been associated with systemic physiologic effects such as reduced postprandial insulin levels and higher high-density lipoprotein cholesterol levels. Consumption of low glycemic index foods has been shown to be related to a reduced risk of type 2 diabetes. Type 2 diabetes has in turn been related to a higher risk of colon cancer, especially colon cancer deaths. If carbohydrate has a protective role in colon cancer prevention, it may lie in the systemic effects of low glycemic index foods. The colonic advantages of different carbohydrates, therefore, remain to be documented. However, there is reason for optimism about the possible health advantages of so-called resistant starches that are slowly digested in the small intestine.

Adjuvants are essential components of vaccines that augment an immunological reaction of organism. New vaccines based on recombinant proteins and DNA, are more save than traditional vaccines but they are less immunogenic. Therefore, there is an urgent need for the development of new, improved vaccine adjuvants. There are two classes of adjuvants: vaccine delivery systems (e.g. emulsions, microparticles, immune-stimulating complexes ISCOMs, liposomes) and immunostimulatory adjuvants (e.g. lipopolysaccharide, monophosphoryl lipid A, CpG DNA, or muramylpeptides). The discovery of more potent and safer adjuvants may allow to development better prophylactic and therapeutic vaccines against chronic infectious (e.g., HSV, HIV, HCV, HBV, HPV, or Helicobacter pylori) and noninfectious diseases as multiple sclerosis, insulin-dependent diabetes, rheumatoid arthritis, allergy and tumors (e.g., melanoma, breast, or colon cancer).

While studies reveal that individuals with both genetic and other chronic medical conditions have difficulty obtaining health insurance, no large-scale studies have compared the health insurance experiences of these groups. The goal of this study was to document and compare the health insurance experiences, attitudes, and beliefs of persons with genetic conditions to those of persons with or at risk for other serious medical conditions. We interviewed approximately 100 adults or parents of children with one of each of the following medical conditions: sickle cell disease (SCD), cystic fibrosis (CF), diabetes, and HIV, and 200 adults with or at risk for breast (BC) or colon cancer (CC). The interview included items related to respondents' experiences and attitudes regarding health insurance. Twenty-seven percent of 597 total respondents self-reported having been denied health insurance or offered insurance at a prohibitive rate. Respondents with single-gene disorders (CF and SCD) were twice as likely to report this as those with non-genetic conditions. Legislation that exists to limit genetic discrimination in insurance addresses genetic risks or traits only, however, rather than protecting those with actual disease. Thus, current legislation may not address the challenges faced by individuals like those in this study, who try to maintain access to health insurance when they or their children are symptomatic with a genetic or other serious health condition. More than one-third of all respondents thought there was a high chance they would be denied health insurance in the future or their insurance would become unaffordable. That individuals with all six health conditions expressed concern regarding their ability to obtain future health insurance suggests policy proposals should be broad-based, addressing the needs and concerns of individuals with diverse health conditions.

There is no doubt that fibers, in particular viscous dietary fibers, have positive effects on human health, both in the prevention and in treatment of chronic diseases. Dietary fibers from psyllium have been used extensively both as pharmacological supplements, food ingredients, in processed food to aid weight control, to regulation of glucose control for diabetic patients and reducing serum lipid levels in hyperlipidemics. Keeping in view, the pharmacological importance of psyllium polysaccharide and its gel-forming nature, this article discusses the therapeutic value of psyllium for the treatment of constipation, diarrhea, irritable bowel syndrome, inflammatory bowel disease-ulcerative colitis, colon cancer, diabetes and hypercholesterolemia and exploitation of psyllium for developing drug delivery systems.
