6-ketoprostaglandin-f1-alpha and Nephrotic-Syndrome

To observe the clinical effect of Modified Taohong Siwu Decoction (MTSD) in treating pediatric intractable nephropathy (PIN).. Ninety-five cases of PIN were divided into 2 groups at random. The 60 cases in the treated group were administered with MTSD and the 35 patients in the control group were treated with heparin. The clinical therapeutic effect and levels of thromboxane B2(TXB2) and 6-keto-prostaglandin F1 alpha before and after treatment were observed.. The total effective rate of the treated group was 81.7%, which was similar to that in the control group (80.0%, P > 0.05). The levels of TXB2 and TXB2/6-ketoprostaglandin F1 alpha ratio were higher in both groups of patients as compared with those of the healthy control (P < 0.01), After treatment, the two criteria were significantly improved in the two groups, as compared with those before treatment, the difference was significant (P < 0.01), while in comparson between the treated and the control group, no significant difference was found (P > 0.05).. MTSD has good effect in treating PIN, it could improve the metabolic unbalance of thromboxane and prostacyclin.

To explore the mechanism of Buyang Huanwu Decoction (BHD) in treating primary nephrotic syndrome (PNS).. Based on the treatment of prednisone acetate and cytoxan, two groups of PNS patients were treated with aspirin and persantin (western medicine group, 35 patients) and BHD and western medicine (TCM-WM group, 35 patients) respectively. The effect on anticoagulation was observed and compared. Plasma levels of thromboxane B2 (TXB2), 6-keto-prostaglandin F1 alpha (6-Keto-PGF1 alpha), endothelin (ET), calcitonin gene related peptide (CGRP) were determined before and after treatment, and at the time of reducing dose and turning to maintenance dose of prednisone. The therapeutic effect of the two groups were also observed. Another group of 30 healthy person was established for control.. The difference of TXB2, 6-Keto-PGF1 alpha, ET, CGRP between patients and healthy persons was very significant before treatment (P < 0.001). Above-mentioned 4 parameters improved synchronously with the clinical improvement in the therapeutic course and they were better in the TCM-WM group than those in the western medicine group (P < 0.001) and the complete remission rate of the former group was also higher than that of the latter (62.9% vs 37.1%, chi 2 = 4.63, P < 0.05).. BHD could improve the therapeutic effect in treating PNS through the mechanism of improving TXB2, 6-Keto-PGF1 alpha, ET and CGRP levels.

While cyclosporine A (CsA) is an effective therapy for nephrotic syndrome, it has nephrotoxic side effects. We compared the anti-proteinuric effects and nephrotoxicity in rats with passive Heymann nephritis (PHN) of CsA and mycophenolate mofetil (MMF).. PHN was induced in female Wistar rats. Two treatment groups consisting of 8 rats each received either 25 mg of CsA or 25 mg of MMF/kg body weight/day and were compared with untreated controls. Kidney function and proteinuria were monitored over 4 weeks. Western blots were used for densitometric analysis of renal cyclooxygenase-2 (COX-2) protein expression. Thromboxane B2 (TxB2) and 6-keto-PGF(1alpha) were determined by radioimmunoassays (RIAs) in renal tissue and urine.. Rats with PHN exhibited a marked proteinuria of 12.76 +/- 4.42 vs. 0.73 +/- 0.28 mg/24 h (p < 0.01) and showed increased glomerular concentrations of TxB2 and 6-keto-PGF(1alpha) (992.6 +/- 216.9 and 1,187.0 +/- 54.2 pg/mg protein, respectively) compared with healthy controls (595 +/- 196.17 and 729 +/- 297.84, respectively) and a strongly induced COX-2 protein expression. CsA and MMF treatment reduced PHN-related proteinuria to 2.10 +/- 1.47 and 1.47 +/- 7.2 mg/24 h, respectively. In rats with PHN, CsA induced a significant deterioration of renal function and enhanced urine excretion of thromboxane A2, paralleled by a significant, twofold increase in COX-2 protein expression and renal prostaglandins. By contrast, MMF treatment in rats with PHN was not nephrotoxic and had no effect on prostaglandin production. COX-2 protein expression under MMF was suppressed.. While the antiproteinuric efficacy of MMF and CsA in PHN was comparable, the absence of nephrotoxicity might favor MMF in the treatment of nephrotic syndrome. The CsA-induced increase in COX-2 expression and COX-2-dependent prostacyclin may indicate a mechanism that compensates nephrotoxicity in the diseased and CsA-exposed kidney.

Plasmic and urinary TXB2 and 6-Keto-PGF1 alpha of 87 patients of nephrotic syndrome (NS) and 25 healthy subjects were measured by RIA, and the influence of Yiqi Huoxue Jiedu decoction (YHJ) and corticosteroid on above-mentioned parameters was investigated.. Plasmic and urinary TXB2 as well as the ratio of TXB2/6-K-PGF1 alpha of both types of NS increased (P < 0.01-0.05). The plasmic TXB2 of II type was higher than that of I type of NS (P < 0.01), 6-K-PGF1 alpha increased as well (P < 0.05). After treatment, plasmic and urinary TXB2 of both types of NS were remarkably lower (P < 0.01), while urinary 6-K-PGF1 alpha increased significantly (P < 0.05). In comparing with pre-treatment investigation, the plasmic 6-K-PGF1 alpha of II type was reduced (P < 0.05). It was shown that YHJ would inhibit the synthesis of TXA2 and regulate the TXA2-PGI2 balance. YHJ was markedly effective in producing TXB2 and 6-K-PGF1 alpha increase, its therapeutical effects was better to patients with Yin Deficiency and both Qi-Yin Deficiency, but not so well with Yang Deficiency Syndrome.

In accordance with the results of examining 40 children with nephrotic and mixed glomerulonephritis, it has been established that in the pathogenesis of the nephrotic syndrome of paramount importance is imbalance of the output of renal prostanoids, manifesting in the predominance of the vasopressor and proaggregate fraction--thromboxane A2 and in the deficiency of its antagonist prostacyclin that exerts a protective action on glomerular filtration. Sodium and water retention in patients with the nephrotic syndrome favours an increase of the content of antidiuretic hormone and plasma renin activity.

To determine if a selective thromboxane (TX)A2 synthetase inhibitor is clinically effective for the treatment of nephrotic syndrome, 11 patients with nephrotic syndrome were treated only with OKY-046, (E)-3-4-(1-imidazolylmethyl)phenyl-2-propenoic acid hydrochloride monohydrate, for at least 8 weeks. Urinary excretion of protein, TXB2, 2,3-dinor-TXB2, and beta-N-acetyl-D-glucosaminidase decreased with OKY-046. Creatinine clearance value, and urinary excretion of 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha), however, did not show any significant change, while serum albumin level increased. Two patients with minimal change nephrotic syndrome showed complete remission only with OKY-046. These results demonstrate that the selective TXA2 synthetase inhibitor is an effective drug for the treatment of chronic glomerulonephritis accompanied by nephrotic syndrome.
