  • Effect of Exogenous Glucocorticoid on Osmotically Stimulated Antidiuretic

Hypocortisolism in secondary adrenocortical insufficiency can result in a clinical picture similar to the syndrome of inappropriate ADH secretion. On the other hand, in vitro and in vivo results provide evidence for ADH suppression in states of hypercortisolism. To test the hypothesis that ADH suppression is of relevance during glucocorticoid therapy, we investigated the influence of prednisolone on the osmotic stimulation of ADH. Design and methods: Seven healthy men were subjected to water deprivation tests with the measurement of plasma ADH (pADH) and osmolality (posmol) before and after glucocorticoid treatment (5 days 30 mg prednisolone per day). Results: Before glucocorticoid treatment, the volunteers showed a normal test with an adequate increase of pADH (basal 0.54G0.2 to 1.9G0.72 pg/ml (meanGS.D.)) in relation to posmol(basal 283.3G8.5 to 293.7G6 mosmol/kg). After prednisolone intake, pADH was attenuated (!0.4 pg/ml) in spite of an increase of posmol from 289.3G3.6 to 297.0G5.5 mosmol/kg.

  • The Necessity and Effectiveness of Mineralocorticoid Receptor Antagonist in the Treatment of Diabetic Nephropathy
    Hypertension Research (2015) 38, 367–374 & 2015 The Japanese Society of Hypertension All rights reserved 0916-9636/15 www.nature.com/hr REVIEW The necessity and effectiveness of mineralocorticoid receptor antagonist in the treatment of diabetic nephropathy Atsuhisa Sato Diabetes mellitus is a major cause of chronic kidney disease (CKD), and diabetic nephropathy is the most common primary disease necessitating dialysis treatment in the world including Japan. Major guidelines for treatment of hypertension in Japan, the United States and Europe recommend the use of angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, which suppress the renin-angiotensin system (RAS), as the antihypertensive drugs of first choice in patients with coexisting diabetes. However, even with the administration of RAS inhibitors, failure to achieve adequate anti-albuminuric, renoprotective effects and a reduction in cardiovascular events has also been reported. Inadequate blockade of aldosterone may be one of the reasons why long-term administration of RAS inhibitors may not be sufficiently effective in patients with diabetic nephropathy. This review focuses on treatment in diabetic nephropathy and discusses the significance of aldosterone blockade. In pre-nephropathy without overt nephropathy, a mineralocorticoid receptor antagonist can be used to enhance the blood pressure-lowering effects of RAS inhibitors, improve insulin resistance and prevent clinical progression of nephropathy. In CKD categories A2 and A3, the addition of a mineralocorticoid receptor antagonist to an RAS inhibitor can help to maintain ‘long-term’ antiproteinuric and anti-albuminuric effects. However, in category G3a and higher, sufficient attention must be paid to hyperkalemia. Mineralocorticoid receptor antagonists are not currently recommended as standard treatment in diabetic nephropathy.

Correspondence to: Dr. Sarabjeet S. Suri, MD. University of Alabama at Birmingham, 1900 University Blvd, THT 321, Birmingham, AL 35223, USA. Email: [email protected]. Abstract: Heart failure (HF) is one of the major causes of morbidity and mortality in the world. According to a 2019 American Heart Association report, about 6.2 million American adults had HF between 2013 and 2016, being responsible for almost 1 million admissions. As the population ages, the prevalence of HF is anticipated to increase, with 8 million Americans projected to have HF by 2030, posing a significant public health and financial burden. Acute decompensated HF (ADHF) is a syndrome characterized by volume overload and inadequate cardiac output associated with symptoms including some combination of exertional shortness of breath, orthopnea, paroxysmal nocturnal dyspnea (PND), fatigue, tissue congestion (e.g., peripheral edema) and decreased mentation. The pathology is characterized by hemodynamic abnormalities that result in autonomic imbalance with an increase in sympathetic activity, withdrawal of vagal activity and neurohormonal activation (NA) resulting in increased plasma volume in the setting of decreased sodium excretion, increased water retention and in turn an elevation of filling pressures.

Although over a billion people are affected worldwide, only half of them receive adequate treatment. Current guidelines on antihypertensive treatment recommend combination therapy for patients not responding to monotherapy, but as the number of pills increase, patient compliance tends to decrease. As a result, fixed-dose combination drugs with different antihypertensive agents have been developed and widely used in recent years. CCBs have been shown to be better at reducing central blood pressure and arterial stiffness than diuretics. Recent studies have reported that central blood pressure and arterial stiffness are associated with cardiovascular outcomes. This trial aims to compare the efficacy of combination of calcium channel blocker (CCB) or thiazide diuretic with an angiotensin receptor blocker (ARB).

  • Managing Diuretic-Induced Hypokalemia in Ambulatory Hypertensive Patients
    Managing Diuretic-Induced Hypokalemia in Ambulatory Hypertensive Patients Richard G.

Many treatment alternatives exist for managing hypokalemia, and physicians aware of all the options will be able to control patients effectively and many times at a much lower cost.
