Table 18-1 Lifestyle modifications 1. Restriction of salt intake to less than 6 g/day 2. Increased intake of BKM120 vegetables and fruitsa Restriction of intake of cholesterol and saturated fatty acid 3. Maintenance of appropriate body weight:

not exceeding BMI ([body weight (kg)]/[height (m)]2) of 25 4. Exercise: indicated for hypertensive patients without cardiovascular disease Regular aerobic exercise for 30 min or longer every day 5. Restriction of alcohol intake: 20–30 g/day or less in terms of ethanol for men and 10–20 g/day or less for women 6. No smoking Comprehensive modification of one’s lifestyle is more effective Quoted from: Lifestyle Modifications in Japanese Society click here of Hypertension Guidelines for the Management of Hypertension (JSH 2004). Hypertens Res 2006;29(Suppl):S1–S105 aIncreased intake of vegetables and fruits is not recommended in patients with severe renal dysfunction, because it may induce hyperkalemia. Also, increased intake of fruits is not recommended in diabetic patients, because it may lead to an increase in calories Salt restriction is particularly essential. Physicians should advise patients to take less than 6 g/day salt. Salt restriction enhances

antihypertensive effects of ACE inhibitors and ARBs. In the elderly, excessive salt restriction may disturb appetite, resulting in dehydration, leading to reduced kidney function. When salt restriction is difficult, a small dose of diuretics may be useful in combination. BIIB057 Concurrent use of thiazide diuretics (CKD stages 1–3) or loop diuretics (CKD stages 3–5) can accelerate salt excretion. However, physicians are to be aware of possible complications of diuretics such as hypokalemia, hyperuricemia, and dehydration. Kidney protection by ACE inhibitors or ARBs Kidney protection by ACE inhibitors and Thymidine kinase ARBs has been demonstrated. These agents are recommended for diabetic nephropathy with hypertension and even without hypertension. Nondiabetic CKD patients are expected to benefit from ACE inhibitors and ARBs. These agents, therefore, are prescribed

if blood pressure is high. Caution for administration of ACE inhibitors or ARBs Administration of ACE inhibitors or ARBs may increase serum creatinine level. Despite this, these agents are allowed to be continued, placing priority on pharmacological effects unless an increment of serum creatinine exceeds 30% of previous level or 1 mg/dL. For example, these agents may be continued if serum creatinine is elevated from 1.34 to 1.74 mg/dL after starting treatment. Serum creatinine and potassium are measured at 2 weeks or 1 month after starting ACE inhibitors or ARBs, and if continued, they are constantly monitored thereafter. If serum creatinine is elevated to the above-mentioned degree, these agents should be reduced in dosage or discontinued, and consultation to nephrologists is required.
