Two elements are associates with symptomatic hyponatremia. Such factors are diuretic at higher dosage (HCTZ dose between 35 and 50 mg) and low salt intake with a preexisting reduction in free water clearance or a high fluid intake [12]. Unless these two www.selleckchem.com/products/salubrinal.html conditions meet, serious hyponatremia is unlikely occur particularly if Forskolin patients are mobile. Uzu et al. [26] showed that treatment with HCTZ 12.5 mg and LOS 50 mg did not induce significant reduction in serum Na concentration. The present

study, however, cast a caution that careful monitoring of serum Na concentration is indispensable in the treatment with HCTZ, even in a low prescribed dose of 12.5 mg. With respect to serum K concentration, our study showed that there was no change in this parameter. Combining LOS with HCTZ exerts a beneficial offsetting effect in K metabolism, because the former increases serum K selleck compound concentration and the latter decreases, diminishing the risk of either hyper-, or hypokalemia. Effect of LOS/HCTZ on BNP and ACR There was a substantial decrease in BNP, a marker for cardiac hypertrophy (Fig. 4). Furthermore, the reduction in BNP was obvious in patients with elevated BNP values and in those who responded well to the therapy, suggesting that the BNP lowering effect depends on BP reduction (Fig. 5). Strict BP control, therefore, appears to be indispensable for cardio-protection. There was a substantial

decrease in ACR, and the effect was profound especially in patients with elevated ACR (Fig. 6). The reno-protective effects of LOS have been demonstrated in the RENAAL study in patients with type 2 diabetic nephropathy

[27]. The risk of a doubling of the serum Cr concentration, end-stage renal disease, or death from any cause, was reduced by about 16–28% with LOS. In addition, the LIFE study, demonstrating the superiority of LOS over atenolol for reduction of CV morbidity and mortality, was accompanied by the reduction in albuminuria [28–30]. The present study clearly confirmed that treatment with LOS/HCTZ is effective to improve microalbuminuria. Decreases in BNP and ACR may portend good clinical outcomes for cardio- and reno-protection. However, longer term follow up would be needed Progesterone to prove such. Effect of LOS/HCTZ on UA metabolism Despite the potent antihypertensive effect, diuretics have been less frequently used in clinical practice for fear of their adverse effects, including increase in serum UA concentration. In the present study, a subtle but significant increase in serum UA concentration was observed in overall patients, although such changes still remained within the normal range (Fig. 7). Of note is that when patients were stratified into a high-UA group and a low-UA group, significant decrease was observed only in the former. The same results were noted in the study by Kita et al.
