Abstract-National guidelines for the prevention and treatment of hypertension recommend sodium reduction, weight loss, the Dietary Approach to Stop Hypertension (DASH) diet, and regular aerobic exercise. However, no trial has assessed the efficacy of simultaneously implementing all of these recommendations. The objective of this study was to determine the effects on blood pressure and other cardiovascular disease risk factors of a comprehensive lifestyle intervention. We conducted a randomized controlled trial of 44 hypertensive, overweight adults on a single blood pressure medication.Participants were randomized to a lifestyle or control group. For 9 weeks, the lifestyle group was fed a hypocaloric version of the DASH diet that provided 100 mmol/d of sodium. This group also participated in a supervised, moderate-intensity exercise program 3 times per week. The control group received no intervention. Outcomes were ambulatory blood pressure, serum lipids, weight, and fitness. At the end of the intervention, mean weight loss in the lifestyle group, net of control, was 4.9 kilograms. In the lifestyle group mean net reductions in 24-hour ambulatory systolic and diastolic blood pressures were 9.5 mm Hg (PϽ0.001) and 5.3 mm Hg (PϽ0.002), respectively. Corresponding changes in daytime systolic and diastolic blood pressures were 12.1 mm Hg (PϽ0.001) and 6.6 mm Hg (PϽ0.001).

The increasing use of corticosteroids, immune modulators, and biologics as a mainstay of therapy in certain Crohn's disease and ulcerative colitis patients have placed these inflammatory bowel disease (IBD) patients at increased risk for a variety of infections, many of which are preventable by prior vaccination. This article provides a review of the issues surrounding immunizations in the IBD patient and a practical guide for clinicians regarding the appropriate vaccinations to administer both before and during immunosuppressive therapy.
