Preserving residual renal function: Is interdialytic acupuncture an add-on option? A case series report.

BACKGROUND: Whether acupuncture therapy contributes to preserving residual renal function (RRF) remains largely unknown. This case series demonstrated the potential beneficial effects of acupuncture for preserving RRF in five patients with end-stage renal disease undergoing hemodialysis (HD) treatment. PARTICIPANTS: HD patients received eight sessions of weekly 30 min interdialytic acupuncture (Inter-A) at ten selected acupoints, namely Yintang (GV29), Yingxiang (LI20), Shuijin (Tung's Acupuncture), Lianquan (CV23), Shangqu (KI17), Tianshu (ST25), Siman (KI14), Hegu (LI4), Zusanli (ST36) and Sanyingjao (SP6). Residual urine volume (rUV) and residual glomerular filtration rate (rGFR) were recorded once every two weeks Outcomes: Changes in rUV and rGFR were calculated using 24 h urine collection data to assess RRF. Variations in hemoglobin, urea Kt/V and serum albumin levels were measured monthly to evaluate HD adequacy. RESULTS: After eight Inter-A sessions, the mean[standard deviation] rUV and rGFR increased from 612[184] ml/day and 1.48[0.94] ml/min/1.73 m2 at baseline to the peak of 803[289] ml/day and 2.04[1.17] ml/min/1.73 m2 at 2- and 4-week follow-up, respectively. The mean percentage difference increased by 31% in the rUV and 37% in the rGFR. Routine measurements of HD adequacy also showed improvements. CONCLUSIONS: Acupuncture might be an optional add-on treatment for HD population with poor control of water; however, further well-designed controlled trials are warranted.

The association between nocturia, hormonal symptoms and bladder parameters in women: an observational study.

OBJECTIVE: Postmenopausal nocturia is poorly understood. This study aimed to identify hormonal and lifestyle factors associated with nocturia and to understand the relative contribution of altered urine production and bladder storage dysfunction in women. DESIGN, SETTING, POPULATION AND METHODS: Women ≥40 years presenting to public continence services were enrolled in a cross-sectional study. A total of 153 participants completed a hormone status questionnaire, a validated nocturia causality screening tool and a 3-day bladder diary. Descriptive statistics and logistic regression models for nocturia severity and bladder diary parameters were computed. RESULTS: Overall, 91.5% reported nocturia, 55% ≥2 /night. There was a difference of 167.5 ml (P < 0.001) in nocturnal urine volume between women with nocturia ≥2 (median 736 ml) versus less often (517 ml). Significant predictors of self-reported disruptive nocturia were age (odds ratio [OR] 1.04, 95% CI 1.002-1.073) and vitamin D supplementation (OR 2.33, 95% CI 1.11-4.91). Nocturnal polyuria was significantly more common with nocturia ≥2 compared with less frequent nocturia (P < 0.002). Exercise for 150 minutes a week was protective for nocturnal polyuria (OR 0.22, P = 0.001). Nocturia index >1.3 was significantly predicted by age (OR 1.07, P < 0.001), regular exercise (OR 0.41, P = 0.036), day flushes (OR 4.00, P = 0.013) and use of vitamin D (OR 2.34, P = 0.043). Maximum voided volumes were significantly lower with nocturia ≥2 versus less often (night: 268 ml versus 350 ml; day: 200 ml versus 290 ml). CONCLUSIONS: Bothersome nocturia in postmenopausal women is associated with changes to both nocturnal diuresis and bladder storage. Regular physical activity, prolapse reduction and oestrogen replacement may be adjunctive in managing bothersome nocturia in women.

San-Ao Decoction () Regulates Urine Volume on Bronchial Asthma Model Mice.

OBJECTIVE: To observe the effect of San-Ao Decoction (, SAD) on water metabolism of bronchial asthra model mice. METHODS: Forty-five female BALB/c mice were randomly divided into control, model and SAD groups by a random number table, 15 mice in each group. A composite method with ovalbumin (OVA) sensitization and challenge was developed to establish bronchial asthma model. Mice in the control group were intraperitoneally injected with distilled water without aerosol inhalation challenge. On day 15-22, 0.3 mL SAD was administered via gastric route in SAD group, one time per day, while an equivalent volume of normal saline was used for gastric administration in the control and model groups. Changes in airway resistance in the inspiratory phase (RI-R-Area) were detected using an AniRes2005 system, and 5-h urine output was collected by metabolic cages. Histopathological changes in lung and kidney were observed by hematoxylin-eosin staining. mRNA expressions of aquaporin (AQP) 1 and AQP2 in kidney were detected by reverse transcription-polymerase chain reaction, and the protein expressions of AQP1 and AQP2 in kidney were detected by immunohistochemistry. Enzyme-linked immune sorbent assay was used to detect the OVA-specific endothelium-1 (ET-1), antidiuretic hormone (ADH), atrial natriuretic peptide (ANP), prostaglandin E2 (PGE2), and angiotensin II (Ang II) levels in serum, lung and kidney tissues, respectively. The nitric oxide (NO) contents in serum, lung, and kidney tissues were tested by chemical method, respectively. RESULTS: Compared with the control group, the serum IgE level in model group increased (P<0.01). Following the pathologic changes in lung tissue, no significant change in kidney tissue was observed among 3 groups. Compared with the control group, the mice in the model group showed elevated airway resistance during inhalation phase, higher mRNA and protein expression levels on AQP1 and AQP2 in kidney tissue and higher ET-1 levels in serum, lung and kidney tissues, ADH and ANP in lung and serum, PGE2 in kidney, Ang II in lung and kidney tissues (P<0.05 or P<0.01), but decreased in 5-h urinary output as well as NO and PGE2 contents in serum and lung tissues (P<0.05 or P<0.01). Compared with the model group, the mice in the SAD group showed a weakened airway resistance in inspiratory phase, lower mRNA and protein expressions of AQP1 and AQP2 in kidney tissues, lower levels of ET-1, ADH, ANP in serum as well as ET-1, ANP, Ang II levels in kidney tissues (P<0.05 or P<0.01), whereas 5-h urinary output, NO content in kidney, ADH, ANP and PGE2 levels in lung and Ang II in serum increased (P<0.05 or P<0.01). CONCLUSION: San-Ao Decoction can regulate the urine volume through regulating AQP1 and AQP2 expression, and the expression of these in the kidneys might be regulated by ET-1, NO and Ang II.

Hyponatremia presenting with hourly fluctuating urine osmolality.

SUMMARY: The etiology of hyponatremia is assessed based on urine osmolality and sodium. We herein describe a 35-year-old Asian man with pulmonary tuberculosis and perforated duodenal ulcer who presented with hyponatremia with hourly fluctuating urine osmolality ranging from 100 to 600 mosmol/kg, which resembled urine osmolality observed in typical polydipsia and SIADH simultaneously. Further review revealed correlation of body temperature and urine osmolality. Since fever is a known non-osmotic stimulus of ADH secretion, we theorized that hyponatremia in this patient was due to transient ADH secretion due to fever. In our case, empiric exogenous glucocorticoid suppressed transient non-osmotic ADH secretion and urine osmolality showed highly variable concentrations. Transient ADH secretion-related hyponatremia may be underrecognized due to occasional empiric glucocorticoid administration in patients with critical illnesses. Repeatedly monitoring of urine chemistries and interpretation of urine chemistries with careful review of non-osmotic stimuli of ADH including fever is crucial in recognition of this etiology. LEARNING POINTS: Hourly fluctuations in urine osmolality can be observed in patients with fever, which is a non-osmotic stimulant of ADH secretion. Repeated monitoring of urine chemistries aids in the diagnosis of the etiology underlying hyponatremia, including fever, in patients with transient ADH secretion. Glucocorticoid administration suppresses ADH secretion and improves hyponatremia even in the absence of adrenal insufficiency; the etiology of hyponatremia should be determined carefully in these patients.

Potential effect of Silybum marianum L. and Cistus ladaniferus L. extracts on urine volume, creatinine clearance and renal function

Objective:To investigate the diuretic and renal effects of Silybum marianum L. and Cistus ladaniferus L. in normal rats.Methods:Four groups of rats were used in each experiment. The first group received water, the second group received Cistus ladaniferus L. extract (100 mg/kg b.wt), the third group received Silybum marianum L. extract (100 mg/kg b.wt), and the fourth group received furosemide (10 mg/kg b.wt). Variables including urine volume, plasma and urine sodium, potassium and creatinine, and creatinine clearance were measured. Two experiments were conducted. A single dose of each intervention was used and the variables were measured during 24 h, and the interventions were given daily for a total of 8 d and the variables were measured during various intervals.Results:The single dose of each plant extract increased urine volume at all-time intervals and increased urine sodium and potassium excretion without affecting plasma sodium and potassium (P<0.05). On the day 8 after daily administration, the plant extracts induced a significant diuresis and natriuresis without affecting serum electrolytes (P<0.05), while furosemide caused hypokalemia. Both plant extracts significantly increased creatinine clearance (P<0.05).Conclusions:Silybum marianum L. and Cistus ladaniferus L. increase creatinine clearance and have a significant diuretic effect without affecting serum electrolytes. Silybum marianum L. is more potent than furosemide or Cistus ladaniferus L.

Diuretic activity of the aqueous crude extract and hot tea infusion of Moringa stenopetala (Baker f.) Cufod. leaves in rats.

Moringa stenopetala (Baker f.) Cufod. is a medicinal plant that has been used for the treatment of different ailments such as hypertension and diabetes in Ethiopia. This study aims to assess the diuretic activity of the aqueous crude extract and hot tea infusion of M. stenopetala leaves in saline-loaded rats. Male Wistar rats were divided into ten groups (n = 5). The control group received distilled water (5 mL/kg), whereas the reference group received Furosemide (10 mg/kg). Groups III-X orally received different doses of aqueous crude extract (62.5, 125, 250, and 500 mg/kg) and hot tea infusion (1, 2, 4, and 6 teaspoons [Tsp]) based on community use. Urine volume was recorded every hour until the end of the 5th hour, and total urine volume of each animal was calculated. The diuretic activity and diuretic action were determined based on the urine output. Additionally, concentration of urinary sodium, chloride, and potassium ions was determined. The urinary Na+/K+ ratio and carbonyl anhydrase activity (Cl-/(Na+/K+)) were also assessed. The findings verified that the aqueous crude extract as well as the hot tea infusion of the leaves of M. stenopetala possesses significant (P < 0.01) diuretic, natriuretic, and kaliuretic effects. The aqueous crude extract (125 mg/kg) and hot tea infusion (2 Tsp) displayed the highest diuretic activity (101% and 96%, respectively) comparable to the reference drug, Furosemide (10 mg/kg). They also displayed a good natriuretic activity. The aqueous crude extract and hot tea infusion revealed a significant Na+ urinary excretion (P < 0.001) and Na+/K+ ratio (P < 0.05) at all test doses. There was also a significant (P < 0.01) Cl- urinary excretion at all test doses of aqueous crude extract except 62.5 mg/kg and all test doses of hot tea infusion except higher doses (4 and 6 Tsp). Thus, the aqueous crude extract as well as the hot tea infusion of the leaves of M. stenopetala causes a plausible increase in the urine volume and concentration of urinary electrolytes in rats.

A two-week, double-blind, placebo-controlled trial of Viola odorata, Echium amoenum and Physalis alkekengi mixture in symptomatic benign prostate hyperplasia (BPH) men.

CONTEXT: As an alternative approach, administration of phytotherapeutic agents in management of benign prostate hyperplasia (BPH), is rapidly growing each day. Different authors have indicated effectiveness of Viola odorata L. (Violaceae), Echium amoenum Fisch. & C.A.Mey. (Boraginaceae) and Physalis alkekengi L. (Solanaceae) in treatment of BPH. However, none have reported the beneficial outcomes of the mixture yet. OBJECTIVE: This study evaluates the therapeutical effects of V. odorata, E. amoenum and P. alkekengi mixture on symptomatic BPH patients. MATERIALS AND METHODS: Eighty six symptomatic BPH patients with International Prostate Symptom Score (IPSS) of more than 13 and prostate volume of more than 30 cm3 were randomly allocated to receive a two-week course of placebo (control group) or 1 mL of mixed hydro-alcoholic solution of P. alkekengi, E. amoenum and V. odorata extracts (1.5, 1 and 1.5% respectively) (treatment group). RESULTS: IPSS score of incomplete urination (42.3 ± 2.04%), frequency of urination (20.08 ± 1.02%), intermittency (40.78 ± 2.16%), urgency (60.91 ± 3.14%), weak stream (50.58 ± 2.14%), straining (55.67 ± 2.53%) and nocturia (40.14 ± 1.89%) in treatment group were significantly decreased after treatment compare to placebo receiving group. Furthermore, the prostate volume (16.92 ± 0.89%) and extant urine volume (28.12 ± 1.36%) also significantly decreased in treatment group compared to control group. No significant side effects or abnormalities in biochemical tests and urinalysis were observed throughout the study. DISCUSSION AND CONCLUSIONS: Based on results, mentioned mixture is safe and effective in improving life quality of patients suffering from BPH.

Does consumption of an aqueous extract of Hibscus sabdariffa affect renal function in subjects with mild to moderate hypertension?

Hibiscus sabdariffa (HS) has been traditionally used as a herbal medicine in Nigeria mainly because of its antihypertensive action. In view of the recent increase in the prevalence of renal failure, we have investigated the effect of HS consumption on renal function in Nigerians with mild to moderate hypertension. A total of 78 newly diagnosed but untreated subjects with mild to moderate hypertension attending the medical outpatients unit of Enugu State University Teaching Hospital (Enugu, Nigeria) were recruited for the study. These subjects were randomly divided into three equally sized groups that received HS or lisinopril (treatment groups) or placebo (control group), once daily for 4 weeks. Indices of renal function (urine volume and creatinine clearance) were measured at baseline and weekly throughout the study period. HS and lisinopril significantly increased (P < 0.001) urine volume compared to placebo, and HS significantly (P < 0.001) increased urine volume more than lisinopril. HS significantly increased (P < 0.001) creatinine clearance compared to placebo whereas lisinopril did not. These results indicate that HS consumption improved indices of renal function in our study population of Nigerians with mild to moderate hypertension.

Objective To observe the clinical efficacy of acupuncture plus moxibustion in the treatment of benign prostatic hyperplasia.Method Sixty cases of benign prostatic hyperplasia were randomly divided into two groups, 30 cases in the treatment group, 30 cases in the control group. The treatment group was intervened by Acupuncture and moxibustion, while the control group was by orally takingJingzhu Qianlie Longbitong capsules. The International Prostate Symptom Score (IPSS), Quality of Life score (QOL), maximal urinary flow rate (Qmax), residual urine volume (RUV) were compared before and after 3 courses of treatment. Result The total effective rate was 93.3% in the treatment group, versus 66.7% in the control group, and the difference was statistically significant (P<0.05); the IPSS score, QOL score, Qmax, and RUV were significantly changed in both groups after intervention (P<0.05).Conclusion The treatment group and the control group both show improvements in IPSS, QOL score and Qmax and reduction of RUV, which proves that acupuncture plus moxibustion can produce a content efficacy in treating benign prostatic hyperplasia.

Effects on milk urea concentration, urine output, and drinking water intake from incremental doses of potassium bicarbonate fed to mid-lactation dairy cows.

Large variation exists in the potassium content of dairy cow feeds and also within a feed type due to soil type and fertilization. Increased ration K concentration causes a subsequent increase in urinary volume and could be expected to also lower milk urea concentration. Six multiparous mid-lactation Swedish Red dairy cows, all fitted with rumen cannulas, were subjected to 3 different levels of K intake in a Latin square experiment with three 2-wk periods to evaluate the effects on concentrations of milk urea and rumen ammonia, urinary output, and drinking water intake. The treatments were achieved by K supplementation on top of a low-K basal ration fed at individual allowances fixed throughout the experiment. The basal ration, consumed at 20.2 kg of dry matter (DM)/d, provided 165 g of crude protein/kg of DM and consisted of grass silage, concentrates, and urea in the proportions 39.3:60.0:0.7 on a DM basis. Potassium bicarbonate supplementation was 0, 616, and 1,142 g/d, respectively, to give total ration K concentrations that were low (LO; 12 g/kg of DM), medium (MED; 23 g/kg of DM), or high (HI; 32 g/kg of DM). Production and composition of milk was not affected by treatment. A linear effect on milk urea concentration was detected, being 4.48, 4.18, and 3.77 mM for LO, MED, and HI, respectively, and a linear tendency for rumen ammonia concentration with 6.65, 6.51, and 5.84 mg of NH3-N/dL for LO, MED, and HI, respectively. Milk urea concentration peaked about 3h after the rumen ammonia peak from the morning feeding, at a level 1.3mM over the baseline. Urinary urea excretion declined linearly (105, 103, and 98 g of urea-N/d for LO, MED, and HI, respectively). Linear increases occurred in urinary output (0.058 ± 0.001 kg of urine/g of K intake; no intercept; coefficient of determination=0.997) and drinking water intake (65.9 ± 2.02 + 0.069 ± 0.004 kg of water/g of K intake; coefficient of determination=0.95). Urinary K concentration leveled off at 12.4 g/L. Urinary creatinine excretion was not affected by K addition, but allantoin excretion increased linearly by 27% from LO to HI, suggesting increased rumen microbial growth. Rumen pH, acetate proportion of total volatile fatty acids, and digestibility of DM, organic matter, and neutral detergent fiber increased linearly with increasing potassium intake. We concluded that increased ration K concentration lowers milk urea concentration with a magnitude significant for the interpretation of milk urea values, but other sources of variation, such as sampling time relative to feeding, may be even more important.

Effect of Modified Zexie Decoction on Renal Aquaporin-2 Expression in Hypertension Rats Induced by High-Salt / 天津医药

Objective To explore the effect of modified Zexie Decoction on renal aquaporin-2 (AQP2) expression in high-salt hypertensive rat. Methods Hypertensive rats model was established by feeding rat with 8%high salt. Rats (n=50) were divided into model group, modern medicine group, traditional Chinese medicine groups of high, medium, low dose, with 10 rats in each group. The other 10 rats were fed with ordinary diet as normal group. Rats in traditional Chinese medi?cine of high, medium, low groups were given Zexie Decoction suspension of 16.2, 10.8 and 5.4 g/(kg·d) respectively;Rats in modern medicine group was given Valsartan hydrochlorothiazide 16.65 mg/(kg·d);the model group and normal group was ad?ministered with equal volume of distilled water. Animals were feed with medications at 1 mL/100 g by gavage for 4 weeks. On the 1st , 4th , 7th , 14th and, 28th day of administration, we measured SBP and collected 24 h urine. We employed immunohis?tochemistry to detect renal AQP-2 protein expression level and RT-PCR to detect renal AQP-2 mRNA transcription level. Results The rank of SBP from high to low is:model group>traditional Chinese medicine medium and low dose groups>traditional Chinese medicine high dose group and western medicine group>normal group. The rank of urine volume from high to low is:Western medicine group and traditional Chinese medicine high dose group>traditional Chinese medicine me?dium and low dose group > normal group, the difference was not statistically significant between traditional Chinese medi?cine medium and low dose group , or between western medicine group and traditional Chinese medicine high dose group. The renal AQP-2 in epithelial cells along the collecting duct wall of rats in model group show brown particles which are darker and wider distributed than those in normal group and traditional Chinese medicine of high, medium, low dose groups. RT-PCR results show that AQP-2 mRNA expression is highest in rats of model group and lowest in rats of traditional Chi?nese medicine high dose group (P<0.05). No statistical significance of AQP mRNA level was found between traditional Chi?nese medicine low group and model group (P < 0.05). Conclusion Modified Zexie Decoction can lower blood pres?sure by inhibiting the expression of AQP-2.

Study on the diuretic activity of Euphorbia fusiformis Buch.-Ham. in albino rats.

The present study was undertaken to evaluate diuretic activity of Euphorbia fusiformis root powder in Wistar strain albino rats. Randomly selected animals were divided into three groups of six animals each. The root powder was suspended in distilled water and administered orally at a dose of 90 mg/kg therapeutically equivalent dose (TED) and 180 mg/kg (TED × 02) to overnight fasted rats. The diuretic activity was evaluated by determination of urine volume and urinary electrolyte concentrations. Test drug showed significant increase in urine volume and urinary electrolyte excretion in a dose-dependant manner. Thus, from this study, it can be concluded that roots of E. fusiformis possess diuretic activity.
