Losartan/hydrochlorothiazide combination is safe and effective for morning hypertension in Very-Elderly patients.

Morning hypertension is an independent risk for cerebrovascular and cardiovascular events. Although the prevalence of morning hypertension increases with age, treatment of morning hypertension has not been established, particularly in Very-Elderly patients. We compared the safety and efficacy of a losartan/hydrochlorothiazide (HCTZ) combination in controlling morning hypertension between Very-Elderly (≥75 years) and Young/Elderly patients (<75 years).

Benefit of losartan/hydrochlorothiazide-fixed dose combination treatment for isolated morning hypertension: The MAPPY study.

Morning hypertension is an established risk factor for cardiovascular events. In the Morning Hypertension and Angiotensin Receptor Blocker/Hydrochlorothiazide Combination Therapy (MAPPY) study, a 50-mg losartan/12.5-mg hydrochlorothiazide combination (Los/HCTZ) lowered morning blood pressure (BP) more effectively than 100-mg losartan (High-Los) in treated hypertensive patients with morning hypertension.

Large blood pressure variability aggravates arteriolosclerosis and cortical sclerotic changes in the kidney in hypertensive rats.

Background: It has been shown that increased short-term blood pressure (BP) variability (BPV) aggravates hypertensive cardiac remodeling in spontaneously hypertensive rats (SHRs) through a cardiac angiotensin II (angII) system. However, little was known about the renal damage induced by large BPV. Thus, histological changes in the kidney were investigated and candesartan, an angII type 1 receptor blocker (ARB), was also examined to see whether it would prevent renal damage in SHRs with large BPV.

BMP type I receptor inhibition attenuates endothelial dysfunction in mice with chronic kidney disease.

The molecular mechanisms of endothelial dysfunction and vascular calcification have been considered independently and potential links are currently unknown in chronic kidney disease (CKD). Bone morphogenetic protein (BMP) receptor signaling mediates calcification of atherosclerotic plaques. Here we tested whether BMP receptor signaling contributes to endothelial dysfunction, as well as to osteogenic differentiation of vascular smooth muscle cells (VSMCs), in a model of short-term CKD.

Laronidase replacement therapy improves myocardial function in mucopolysaccharidosis I.

We assessed whether laronidase (recombinant human α-L-iduronidase) replacement therapy could improve left ventricular (LV) myocardial function in a 49-year-old woman with mucopolysaccharidosis I (MPS I) and valvular heart disease. After 6 months of laronidase treatment, the concentration of urinary uron acid decreased by 78.8%.
