Chronic inflammation with the presence of excess serum acute-phase proteins, cytokines and cell adhesion molecules is increasingly being implicated in atherosclerosis. The association between inflammatory bowel disease (IBD) and coronary artery disease (CAD) is unstudied. This is a preliminary, thesis-generating cross-sectional study aimed at evaluating the presence of traditional atherosclerotic risk factors in patients with IBD and CAD compared with the control population. The medical records of 42 consecutive IBD patients with CAD from 1999 to 2005 (27 men) were reviewed for the Framingham risk factors. The Framingham risk score (FRS) is calculated based on age, sex, hypertension, diabetes and hyperlipidemia. FRS of patients with IBD and CAD was compared with the FRS of 137 age- and sex-matched (102 men) consecutive patients with CAD (controls). When the Framingham risk score adjusted for group and gender with age as a covariate, the adjusted total FRS score was higher in patients with CAD alone (10.0 [3.75]) as compared to those with; IBD and CAD: (8.1 [3.47]; p = 0.001). FRS is lower in cases (patients with IBD and CAD) when compared with the controls (CAD alone).

Patients with inflammatory bowel disease (IBD) often rely on their gastroenterologist for healthcare maintenance. In addition, the gastroenterologist also provides guidance to the patient's primary care physician on a broad range of issues such as vaccinations, osteoporosis screening, and cancer/dysplasia surveillance. Appropriate vaccinations should be administered to patients with IBD, particularly those likely to receive immunosuppression. Live virus vaccines are not appropriate for patients on immunosuppressive therapy, and therefore should be anticipated and given prior to initiating immunosuppression. Screening for osteoporosis is based on a combination of individual risk factors, but a history of prolonged (>3 months) steroid use over 10 mg is reason enough to obtain dual-energy x-ray absorptiometry scanning. Smoking cessation also falls within the realm of the gastroenterologist, as current smoking has a negative impact on Crohn's disease and cessation can be related to exacerbation in ulcerative colitis. Cancer screening includes not only colorectal cancer, but discussion regarding cervical dysplasia, skin cancer, and prostate cancer. Other primary care issues include hypertension and cholesterol monitoring, depression, and ocular health. A comprehensive understanding of all of the issues that can affect a patient with IBD throughout their life cycle is important, as it can impact their natural history, medication decisions, and overall outcomes.

There has been an ample interest in delivery of therapeutic molecules using live cells. Oral delivery has been stipulated as best way to deliver live cells to humans for therapy. Colon, in particular, is a part of gastrointestinal (GI) tract that has been proposed to be an oral targeted site. The main objective of these oral therapy procedures is to deliver live cells not only to treat diseases like colorectal cancer, inflammatory bowel disease, and other GI tract diseases like intestinal obstruction and gastritis, but also to deliver therapeutic molecules for overall therapy in various diseases such as renal failure, coronary heart disease, hypertension, and others. This review provides a comprehensive summary of recent advancement in colon targeted live bacterial cell biotherapeutics. Current status of bacterial cell therapy, principles of artificial cells and its potentials in oral delivery of live bacterial cell biotherapeutics for clinical applications as well as biotherapeutic future perspectives are also discussed in our review.

The natural selection hypothesis suggests that lighter skin colour evolved to optimise vitamin D production. Some authors question if vitamin D deficiency leads to sufficient health problems to act as a selection pressure. This paper reviews the numerous effects of vitamin D deficiency on human health and argues that vitamin D deficiency is sufficient to pose as a potent selection pressure for lighter skin colour. Vitamin D deficiency manifesting as rickets and osteomalacia are sufficient to impair reproductive success, but additionally, animal studies and some clinical observations suggest that vitamin D may have more direct impact on human fertility. Vitamin D deficiency may lead to a whole host of clinical conditions which impair health and increase mortality rates: increase susceptibility to bacterial and viral infections; rickets, osteomalacia and osteoporosis, with increased risk of falls and fractures; increased risk of cancers; hypertension and cardiovascular disease; maturity onset diabetes; autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease and Type 1 diabetes; and gum disease. We submit that at higher latitudes, lighter skin colour evolved to facilitate vitamin D production under conditions of low ultra-violet B radiation in order to avoid a plethora of ill health, reproductive difficulties and early mortality.

Drugs used for treating inflammatory bowel disease are known to have a number of gastrointestinal and liver adverse effects. 5-ASA products are relatively safe and have few adverse events. In contrast sulfasalazine has side effects in 11-40% of treated patients including fatigue, nausea, abdominal pain and diarrhoea. Glucocorticoids can induce or propagate peptic ulcers and upper GI bleeding especially in combination with NSAIDs. Thioguanins may have severe gastrointestinal side effects including gastrointestinal complaints (in up to 12%), hepatotoxicity (up to 4%) and pancreatitis (1%). Nodular regenerative hyperplasia (NRH) is an important potential side effect of thiopurine therapy especially in men with Crohn's disease after ileocecal resection. NRH may ultimately lead to portal hypertension. A major concern of methotrexate therapy in IBD besides myelosuppression and pulmonary fibrosis is hepatotoxicity. 5mg of folic acid substitution per week potentially decreases gastrointestinal side effects by 80% without interfering with the efficacy of methotrexate. Besides renal dysfunction, tremor, hirsutism, hypertension and gum hyperplasia cyclosporine is known to have a number of gastrointestinal side effects that occur with less frequency such as diarrhoea (up to 8%) nausea and vomiting (up to 10%) and hepatotoxicity in 1-4%. Rare gastrointestinal adverse events are gastritis and peptic ulcers. Paying attention to these potential deleterious side effects is mandatory for physicians treating IBD patients.

The PROLONG randomised clinical trial showed that an abnormal D-dimer at one month after vitamin K antagonist (VKA) suspension for a first episode of unprovoked venous thromboembolism (VTE) is associated with a higher risk of recurrence. However, other patient characteristics, such as comorbidities, in combination with D-dimer could also influence the recurrence risk. It was the objective of this study to assess the predictive value of comorbidities and D-dimer in combination for recurrence after withdrawal of VKA in patients enrolled in the PROLONG study. On the day of VKA suspension, the presence of known (coronary, peripheral,cerebral) vascular disease, chronic inflammatory bowel disease, chronic obstructive pulmonary disease, autoimmune disease, diabetes, arterial hypertension, obesity and dyslipidaemias was registered. D-dimer was measured at 30 +/- 10 days afterwards. The primary outcome was recurrent objectively documented VTE. Mean follow-up was 2.55 years. An abnormal D-dimer was observed in 44% (135/309) of patients with comorbidities and in 29% (87/299) of patients without (p=0.0003). An on-treatment analysis was conducted in 483 patients in whom VKAs were not resumed. In patients with a normal D-dimer, recurrences were observed in 14.3% (24/168) of patients with comorbidities and 10.8% (22/203) of subjects without (p=ns). In patients with an abnormal D-dimer, recurrences were observed in 24.6% (16/65) patients with comorbidities and 21.3% (10/47) of patients without (p=ns). Although abnormal D-dimer levels were significantly more frequent in patients with comorbidities, D-dimer was an independent risk factor for recurrence and the presence of comorbidities did not increase the risk of recurrence associated with an abnormal post-anticoagulation D-dimer.

Within endocrinology, the long-term management of Turner syndrome (TS) in adults is fast becoming a specialist subject in its own right. The complications of TS can affect every system in the body, and the main reason why it falls to endocrinologists to coordinate health care is that many features are clearly within the endocrine remit: hypothyroidism, diabetes, hypertension, osteoporosis, hypogonadism. Endocrinologists as general physicians can often cover surveillance of problems in other areas such as congenital heart disease, inflammatory bowel disease and deafness, calling upon specialist input only if the need arises. In this way, a simple 'one stop shop' can offer a well-woman service for women with TS in a cost-effective manner. Such a service requires a multidisciplinary approach.

Hypertrophic pachymeningitis is rarely observed in inflammatory bowel disease. We report a woman with ulcerative colitis whose biopsy-confirmed hypertrophic pachymeningitis was complicated by cerebral venous sinus thrombosis and intracranial hypertension and required ventriculostomy and steroid therapy. This report highlights the challenges of the diagnosis and management of hypertrophic pachymeningitis from an unusual primary cause.

Glucocorticoids (GC) are drugs commonly used, by approximately 1% of the total adult population as anti-inflammatory and immunosuppressive therapies for asthma, inflammatory bowel disease, dermatological, ophthalmic, neurological, and rheumatic autoimmune diseases. Supporting evidence exists of GC use in both immune mediated and non-immune mediated heart disease. The molecular mechanisms by which GC induces immune-modulation and direct cardioprotection, are complex and not fully understood. We review herein, the current knowledge of GC use in various immune-mediated or non-immune mediated cardiovascular conditions. GC have been investigated in autoimmune, inflammatory and idiopathic heart diseases such as atrio-ventricular conduction abnormalities, rheumatic fever, myocarditis, dilated cardiomyopathy, Churg-Strauss syndrome, Kawasaki disease and sarcoidosis. GC therapy has been studied in non-autoimmune and non-inflammatory indications such as acute myocardial infarction, angina, postpericardiotomy syndrome and other pericardial diseases, endocarditis and cardiac amyloidosis, as well as in invasive cardiology, coronary interventions, and cardiopulmonary-bypass surgery. Despite GC's role as natural, physiologic regulators of the immune system, cardiovascular adverse outcomes may occur. Some of the well-known side effects of GC therapy involve bone, metabolic, and cardiovascular systems and include osteoporosis, fractures, dyslipidemia, diabetes, obesity, and hypertension.

The aim of this paper is to review the latest data on the pharmacological modulation of asymmetric dimethylarginine in human disease. When the terminal nitrogens of the guanidine portion of an arginine become methylated through the action of N-methyl transferases, two chemically close, but physiologically different amino acids are synthesized: symmetric and asymmetric dimethylarginine. The vascular origin of asymmetric dimethylarginine and its inhibitory activity on endothelial nitric oxide synthase give it an important role in certain diseases in which microcirculation is compromised: hypertension, atherosclerosis, inflammatory bowel disease, and diabetes. This review discusses the role that asymmetric dimethylarginine plays in the development of vascular disease, and, wherever possible, evaluates its use in clinical diagnosis. The fact that a number of chemically unrelated drugs, such as angiotensin II antagonists, selective beta- 1 adrenergic antagonists, plant phenolics, statins, and farnesoid X receptor agonists have all been found to reduce dimethylarginine levels in plasma or tissue allows for an integrated study. Although it is difficult to determine exactly why these various agents all have the same effect on arginine metabolism, an explanation of their mechanisms of action is needed. We have thus analyzed the mechanisms involved and reviewed potential trends in the therapeutic use of these drugs.
