Spironolactone

Uretic, or oxytocic agonistic analogs of neurohypophysial hormones on pregnenolone accumulation by cultured rat testicular cells. Testicular cells were cultured for 8 days without treatment as described in Fig. 2 and reincubated for an additional 7 2 h with cyanoketone 10-O M ; and spironolactone los5 M ; in the presence or absence of increasing concentrations 10-'1-10-6 M ; of [PhezOrn8] oxytocin, dVDAVP, or [Thr4Gly7]oxytocin. Medium content of pregnenolone was measured by radioimmunoassay. The results represent mean + - S.E. of quadruplicate determinations.
An article in the August 5, 2004 New England Journal of Medicine found a drug proven beneficial in heart failure was associated with increased risk of serious adverse effects when used in the "real-world."1 In September 1999, a prospective clinical trial known as "RALES" found spironolactone decreased risk of death among severe heart failure patients without causing significant hyperkalemia hyperkalemia is a potential serious adverse effect of spironolactone ; .2 As a result of this trial, spironolactone is recommended by guidelines for severe heart failure in persons with preserved renal function and normal potassium.3 In August 2004, Canadian researchers, in a retrospective time-series analysis, examined trends in spironolactone utilization and hyperkalemia-associated hospitalization.1 Conversely to the clinical study, this analysis found no evidence of benefit with increased spironolactone use, but did find increases in the rates of hospitalization and death due to hyperkalemia. The table on the following page summarizes, quantitatively, the disparate findings. Potential reasons for the discrepancy in results include: The controlled clinical trial included carefully selected patients. `Real-world' analyses of spironolactone use have found the drug is widely used in persons who are different, particularly in terms of age, severity of heart disease, and kidney function, from those in the pivotal clinical trial. Patients in the clinical trial were closely followed, with numerous scheduled tests of serum potassium levels and kidney function. Increasing use of -blockers, which can also cause hyperkalemia, in heart failure. In the Canadian health system analysis, 42% were on -blockers, compared to 10% in the pivotal clinical trial. A prospective clinical trial with the newer aldosterone antagonist, Inspra eplerenone ; found the drug beneficial in patients who had a heart attack.4 However, in that trial, eplerenone was found to have an increased risk of serious hyperkalemia 5.5% of patients ; compared with placebo 3.9% ; . Thus, concerns about hyperkalemia with the clinical use of spironolactone are also applicable to eplerenone. A comment in the Wall Street Journal summarized the Canadian analysis: "Everyone assumes that what you get in a clinical trial is what you will see in clinical practice." but "the broader population is always at greater risk for side effects than patients in a clinical trial."5 To take advantage of the proven benefit of spironolactone in heart failure, and to guard against the phenomenon described in the quote above, programs designed to encourage use in the appropriate population with vigilant monitoring of known adverse effects may be helpful: Spironolacotne should be reserved for those patients with severe heart failure current or recent New York Heart Association class IV, ejection fraction 35% ; , but with adequate renal function. Spironolactonr doses should generally not be titrated above those most commonly used in clinical trials, which was 25 mg daily. Care should be used when administering spironolactone with other agents that increase potassium, including potassium sparing diuretics, potassium supplements, ACE inhibitors and angiotensin receptor blockers, and -blockers. Careful monitoring of serum potassium and renal function is warranted.
Priority should be given to ensuring that available medicines have been made according to good manufacturing practices and are of assured quality. Factors that need to be considered include: -- knowledge of, and confidence in, the origin of the product; -- the pharmaceutical stability of the product, particularly in the environment that it will be used; -- where relevant, bioavailability and bioequivalence information. It is recommended that all medicines be purchased from known manufacturers, their duly accredited agents, or recognized international agencies known to apply high standards in selecting their suppliers.

Therapeutic benefit of spironolactone in experimental chronic cyclosporine A nephrotoxicity. Background. Cyclosporine A CsA ; is an immunosuppressive drug used to prevent tissue allograft rejection. However, its long-term utilization is limited due to chronic nephrotoxicity for which no prevention is available. This study evaluated the effect of spironolactone on renal functional and structural alterations induced by CsA, and assessed whether the protective effect was associated with a reduction of transforming growth factor- TGF- ; and the change of extracellular matrix protein mRNA level. Methods. Male Wistar rats fed with low sodium diet were divided in four treatment groups: vehicle, CsA 30 mg kg ; , spironolactone 20 mg kg ; , or CsA spironolactone. After 21 days, creatinine clearance CCr ; , blood CsA, arteriolopathy in renal tissue, and TGF- , collagen I, collagen IV, fibronectin, and epidermal growth factor EGF ; mRNA levels in renal cortex were determined. Results. CsA reduced the CCr and up-regulated TGF- , collagen I and fibronectin mRNA expression with a significant development of arteriolopathy, and reduced EGF mRNA levels. In contrast, spironolactone administration prevented the fall in renal function and TGF- , collagen I, and fibronectin up-regulation, together with a reduction of arteriolopathy and tubulointerstitial fibrosis. Conclusion. Our data show that aldosterone plays an important role as a mediator of renal injury induced by CsA. Thus, mineralocorticoid receptor blockade may be a potential strategy to prevent CsA nephrotoxicity.

Drug-Interactions Drugs that inhibit CYP2D6 can be expected to increase plasma levels of nebivolol. When BYSTOLIC is co-administered with an inhibitor or an inducer of this enzyme, patients should be closely monitored and the nebivolol dose adjusted according to blood pressure response. In vitro studies have demonstrated that at therapeutically relevant concentrations, d- and I-nebivolol do not inhibit any cytochrome P450 pathways. Digoxin: Concomitant administration of BYSTOLIC 10 mg once daily ; and digoxin 0.25 mg once daily ; for 10 days in 14 healthy adult individuals resulted in no significant changes in the pharmacokinetics of digoxin or nebivolol see PRECAUTION, Drug Interactions ; . Warfarin: Administration of BYSTOLIC 10 mg once daily for 10 days ; led to no significant changes in the pharmacokinetics of nebivolol or R- or S-warfarin following a single 10 mg dose of warfarin. Similarly, nebivolol has no significant effects on the anticoagulant activity of warfarin, as assessed by Prothrombin time and INR profiles from 0 to 144 hours after a single 10 mg warfarin dose in 12 healthy adult volunteers. Diuretics: No pharmacokinetic interactions were observed in healthy adults between nebivolol 10 mg daily for 10 days ; and furosemide 40 mg single dose ; , hydrochlorothiazide 25 mg once daily for 10 days ; , or spironolactone 25 mg once daily for 10 days ; . Ramipril: Concomitant administration of BYSTOLIC 10 mg once daily ; and ramipril 5 mg once daily ; for 10 days in 15 healthy adult volunteers produced no pharmacokinetic interactions. Losartan: Concomitant administration of BYSTOLIC 10 mg single dose ; and losartan 50 mg single dose ; in 20 healthy adult volunteers did not result in pharmacokinetic interactions. Fluoxetine: Fluoxetine, a CYP2D6 inhibitor, administered at 20 mg per day for 21 days prior to a single 10 mg dose of nebivolol to 10 healthy adults, led to an 8fold increase in the AUC and 3-fold increase in Cmax for d-nebivolol see PRECAUTIONS, Drug Interactions ; .

Spironolactone and digoxin drug interaction

Hyperkalemic Cardiac Arrhythmia Secondary to Sppironolactone Chalat Pongpaew, Revadee Na Songkhla and Robert L. Kozam Chest 1973; 63; 1023-1025 DOI 10.1378 chest.63.6.1023 This information is current as of July 27, 2008. Medicine. Around 1919 it was observed that organic mercury compounds used for syphilis caused diuresis and were beneficial in oedema fluid retention ; associated with heart failure. However, the side-effects were considerable and although many organic mercurial compounds were made, they have now passed out of use. The birth of modern diuretic medicines arose from another chance observation, namely that people being treated for rheumatic fever and bacterial infections with sulfa drugs also had increased urine output. In 1949 a sulfa drug was given to three people with marked oedema due to heart failure, and all three showed dramatic improvement. Long-term toxicity was again a problem. Building on these observations, research chemists prepared modified sulfa drugs, leading to the identification of chlorthiazide, which was even better at reducing both oedema and high blood pressure. They were also safer to use and with further chemical modification led to the introduction of acetazolamide in 1950. This compound was 300 times more potent and soon became the main antihypertensive used. It remains available today. Further advances led to the development of other thiazide diuretics. By the early 1960s loop diuretics with a different mechanism of action had been discovered, followed quickly by the potassium-sparing diuretics such as spironolactone and amiloride, many of which are still a mainstay in the treatment of heart failure. In parallel with these advances, other pharmacologists were unravelling the mechanism of the rise in blood pressure that was observed when extracts of adrenal gland were injected. In 1913 it emerged that adrenaline could cause the constriction of blood vessels or their relaxation, depending on their location. This resulted in the proposal that there may be two kinds of receptors, now named alpha and beta. The latter were to become major players in the design of medicines for heart disease. The first betablockers were identified in 1958 by Sir James Black, for which he received the Nobel Prize for and carvedilol.

High blood pressure and unhealthy cholesterol levelers -- the same important risk factors for heart disease and stroke -- are also risk factors for Alzheimer's disease. In fact, they appear to be more important than ApoE4, the genetic factor most commonly associated with Alzheimer's disease. High Blood Pressure. Some studies have reported an association between Alzheimer's disease and systolic hypertension the higher and first number in blood pressure measurement ; . Furthermore, some studies report a lower risk for Alzheimer's disease in patients whose blood pressure was reduced. Nevertheless, although hypertension is strongly linked to memory and mental difficulties, stronger evidence is needed to prove any causal relationship between hypertension and Alzheimer's disease. For example, some studies, including a large community study, report no relationship. High Cholesterol Levels. There has been research suggesting an association between high cholesterol levels and Alzheimer's disease AD ; in some people. A number of recent studies support the link between Alzheimer's disease and cholesterol by suggesting that certain cholesterol-lowing drugs statin drugs known as statins may be protective against Alzheimer's disease. High Homocysteine Levels. Homocysteine is an amino acid that has been identified as a modest risk factor in heart disease. Now, it has also been associated with a higher risk for Alzheimer's disease. High levels are general due to deficiencies of the B vitamins B6, B12, and folate. Such vitamins are also related to nerve protection. Researchers theorize that homocysteine impairs the ability of DNA to repair nerve cells. The weakened cells are then more vulnerable to the harmful effects of oxidized beta amyloid and rosuvastatin. NASAL ADMINISTRATION OF REMIFENTANIL IMPROVES CONDITIONS FOR INSERTION OF A LARYNGEAL MASK AIRWAY LMA ; FOLLOWING SEVOFLURANE INDUCTION IN CHILDREN AUTHORS: S. T. Verghese, R. S. Hannallah, M. P. Brennan, J. L. Yarvitz, K. M. Patel AFFILIATION: Children's National Medical Center, Washington, DC. INTRODUCTION: This study compares conditions for insertion of a Laryngeal Mask Airway LMA ; and airway response to LMA insertion gagging, coughing and or movement ; after sevoflurane induction, with or without supplementary intranasal administration of one of three doses of remifentanil 1, 1.5 or 2 mcg kg ; vs. saline in children 1- 7 yr. of age at 90 seconds following drug administration. METHODS: Anesthesia was induced using nitrous oxide oxygen and 8% sevoflurane. Sixty seconds later, nasal remifentanil 1, 1.5 or 2 mcg kg ; or saline was administered. Anesthesia induction continued with 5% sevoflurane in oxygen, with the child breathing spontaneously. A principal investigator, who was blinded to the dose of remifentanil, attempted LMA insertion 90 seconds after nasal drug administration, and scored the response. End-tidal sevoflurane concentration was recorded immediately before and after LMA insertion in each patient. Following LMA insertion, ventilation was assisted using the same gas mixture until the respiratory rate returned to base-line value, or for a minimum of ten minutes, whichever occurred earlier. RESULTS: To date, 52 patients have been studied. Good or excellent conditions for LMA insertion were seen in 93% of patients who received nasal remifentanil vs. 80% of controls. There was no difference in end-tidal sevoflurane or CO2 concentration among patients in the four groups. Patients who received remifentanil had significantly lower respiratory rate from 5 until 10 minutes following nasal administration vs. saline controls. There were no complications associated with the nasal administration of study drugs. Serum remifentanil levels at the time of LMA insertion are pending. DISCUSSION: Conditions for LMA insertion in adults following a single vital capacity breath of sevoflurane at 90 seconds compares favorably with those after propofol induction. Ninety seconds were chosen in adults and used in this study ; because it represented the time at which all patients would have completed their vital capacity breath. Remifentanil is commonly used by intravenous route to obtund the airway response to tracheal intubation or LMA insertion in adults, and more recently following IV induction in children. The use of the intranasal route to administer other lipophilic drugs e.g. fentanyl and sufentanil ; is well documented, especially before IV access is established. Our preliminary results indicate that nasal administration of remifentanil is a safe and potentially effective adjuvant technique to facilitate LMA insertion in children.

Glycoprotein IIb IIIa antagonists: The glycoprotein IIb IIIa agents are not recommended in conjunction with thrombolytic therapy as they increase the incidence of major and minor bleeding.57 However, these agents are used practically in every patient who is undergoing primary PCI.2, 4, 5, 21 There are different protocols for using these agents. Abciximab has been most extensively used in cardiac catheterization laboratory during primary PCI and it is reasonable to start treatment with abciximab as early as possible in patient scheduled for PCI. The data on tirofiban and eptifibatide in primary PCI are far more limited than for abciximab. However, these agents can be used as alternatives to abciximab during primary PCI. Converting enzyme inhibitors angiotensin receptor blockers: Oral ACE inhibitors ARBs if intolerant ; should be initiated within 24 hours, especially after an anterior infarction, pulmonary congestion, congestive failure or an LVEF 40% in the absence of systemic hypotension ; .2, 4 Beta-blockers: Intravenous beta-blockers should not be given as part of initial therapy. 58 Oral beta-blockers may be initiated once the patient's clinical condition has remained stable for atleast 24-48 hours. 2, 4, 58 Non-dihydropyridine, rate reducing calcium channel blockers can be used if beta-blockers are contraindicated and if LV function is normal. HMG-CoA reductase inhibitors: Therapy with statins atorvastatin preferably ; should be initiated as early after the MI as possible. In the clinical trials, high dose of atorvastatin 4080 mg has been utilized. Aldosterone antagonists: In patients with severe LV systolic dysfunction and congestive failure after MI, eplerenone if unavailable, spironolactone can be used instead ; should be added to standard therapy.2, 4 Magnesium: Patients with documented torsades de pointes should receive intravenous magnesium as a bolus of 1-2 g over 5 minutes and those with low serum magnesium levels should receive supplementation.2, 4 Glucose-Insulin-Potassium infusion: There is no role for GIK infusion in the management of STEMI. However, diabetic patients should receive insulin infusions to achieve good blood sugar control. Management of STEMI patients after thrombolysis: Risk stratification is a continuous process and requires the updating of initial assessment with data obtained during the hospital stay. The management of STEMI after thrombolysis has undergone a major change. Thrombolysis, even if successful should not be considered as a final treatment. The incidence of reocclusion, reinfarction remains high. Four randomized [SIAM III, GRACIA1, CAPITAL-AMI, and the Leipzig Prehospital Lysis Study LPLS ; ] studies 59-62 have contributed to recommend routine coronary angiography and-if applicable-PCI early postthrombolysis. On the basis of these studies recent European Society Guidelines 5 recommend coronary angiography in every patient within 24 hours of thrombolysis irrespective of results of thrombolysis ; . These studies have shown that early routine coronary angiography followed by necessary intervention is superior to conservative approach where angiography and intervention is guided by ischemia driven symptoms or stress testing. An excellent editorial63 summarizes the current practice of thrombolysis Lyse ; first and then stent. The indications for coronary angiography following thrombolysis are shown in Table 12. In situations where facilities for coronary angiography are not immediately available, risk stratification prior to hospital discharge is recommended using non-invasive techniques. All patients should have echocardiography to know the LV function prior to discharge. Stress echocardiography can be used in those patients who may not be able to perform stress testing. Exercise testing two weeks after STEMI may be performed in stable patients with good LVEF 40% or above ; to assess functional capacity, establish exercise parameters for cardiac rehabilitation, JAPI VOL. 54 JUNE 2006 and terazosin.

L. Prescribing, dispensing, or administering a drug by a veterinarian which results in a finding of a forbidden substance. In the event a positive report is received by the Federation for a horse or pony to which a forbidden substance has been administered in any manner and the veterinarian is identified in any manner as the source of said forbidden substance, said violation will be addressed pursuant to GR412. General Before instituting therapy with CRESTOR rosuvastatin calcium ; , an attempt should be made to control hypercholesterolemia with appropriate diet, exercise, weight reduction in overweight patients, and to treat other underlying medical problems and associated cardiovascular risk factors. The patient should be advised to inform subsequent physicians of the prior use of CRESTOR or any other lipid-lowering agent. Cardiovascular Co-enzyme Q10 ubiquinone ; Ubiquinone levels were not measured in CRESTOR clinical trials. Significant decreases in circulating ubiquinone levels in patients treated with other statins have been observed. The clinical significance of a potential long-term statin-induced deficiency of ubiquinone has not been established. It has been reported that a decrease in myocardial ubiquinone levels could lead to impaired cardiac function in patients with borderline congestive heart failure see REFERENCES ; . Endocrine and Metabolism Endocrine Function HMG-CoA reductase inhibitors interfere with cholesterol synthesis and lower cholesterol levels and, as such, might theoretically blunt adrenal or gonadal steroid hormone production. Rosuvastatin demonstrated no effect upon nonstimulated cortisol levels and no effect on thyroid metabolism as assessed by TSH plasma concentration. In CRESTOR treated patients, there was no impairment of adrenocortical reserve and no reduction in plasma cortisol concentrations. Clinical studies with other HMG-CoA reductase inhibitors have suggested that these agents do not reduce plasma testosterone concentration. The effects of HMG-CoA reductase inhibitors on male fertility have not been studied. The effects, if any, on the pituitary-gonadal axis in premenopausal women are unknown. Patients treated with rosuvastatin who develop clinical evidence of endocrine dysfunction should be evaluated appropriately. Caution should be exercised if an HMG-CoA reductase inhibitor or other agent used to lower cholesterol levels is administered to patients receiving other drugs e.g. ketoconazole, spironolactone or cimetidine ; that may decrease the levels of endogenous steroid hormones. Lipoprotein a ; In some patients, the beneficial effect of lowered total cholesterol and LDL-C levels may be partly blunted by a concomitant increase in the Lipoprotein a ; [LP a ; ] concentrations. Present knowledge suggests the importance of high LP a ; levels as an emerging risk factor for coronary heart disease. It is thus desirable to maintain and reinforce lifestyle changes in high risk patients placed on rosuvastatin therapy and candesartan.
3 AGE-RELATED CHANGES IN THE SYNAPTIC PLASTICITY IN APP + PS1 TRANSGENIC MICE I. Gureviciene, R. Pussinen, H. Tanila, A. Ylinen Dept. Neuroscience and Neurology, University of Kuopio, Finland Background: Transgenic mice carrying APPswe and PS1 mutations associated with familiar Alzheimer's disease develop amyloid depositions in the hippocampus and cortex, and demonstrate age-related spatial memory impairment. To elucidate the underlying mechanisms, we studied synaptic plasticity by recording long-term potentiation LTP ; in hippocampal slices. Methods: Male mice, transgenic TG ; and littermate controls NT ; , 3 n and 17 n 21 ; months old, were used in the study. Field EPSPs evoked by Schaffer collateral stimulation were recorded in the CA1 field in standard 450 m hippocampal slices. LTP was induced by theta burst stimulation at 100 Hz. Results: The baseline EPSP slopes were larger in young NT than in young TG mice p 0.003 ; but the genotype difference did not reach significance among the aged mice p 0.10 ; . The stimulation current needed to elicit the maximum population spike free EPSP did not differ between the genotypes. The LTP measured as EPSP slope either 15, 45 or 60 min after the induction, did not differ between the age groups or the genotypes. Conclusion: The age-related spatial learning impairment in APP + PS1 mice unlikely results from impaired synaptic plasticity in the field CA1 of the hippocampus.

Abstract In a previous study it was shown that acute perfusion of aldosterone into the isolated carotid sinus decreased baroreceptor activity. The aim of the present study was to determine whether chronic, systemic administration of aldosterone also depresses baroreflex function. In six conscious dogs, the baroreflex was determined before and 10 days after an osmotic minipump containing aldosterone 100 ixg kg in 2 ml ; was implanted. The slope of the relation between systolic arterial pressure and heart rate was significantly blunted after aldosterone administration 9.10.7 versus 13.31.2 for nitroglycerin, P .0l; 23.4 + 5.0 versus 40.1 + 5.0 for phenylephrine, P .01 ; . Baroreflex slopes did not change in a sham group minipump with saline ; and an aldosterone plus spironolactone 600 mg d ; group. Plasma aldosterone levels were significantly elevated after the aldosterone minipump was implanted 44372 versus 3711 pg ml, f .001 ; . Mean arterial pressure was not significantly increased after aldosterone 106.5 3.8 versus 100.42.6 mm Hg, P 2 ; . On the 10th day after aldosterone or saline infusion, an acute experiment was carried out. Single baroreceptor fibers were recorded from the carotid sinus nerve. Compared with the sham group, the threshold was significantly elevated in the aldosterone group 111.3 + 2.1 versus 85.82.8 mm Hg ; , and the peak discharge rate was markedly decreased 32.51.5 versus 54.7 + 2.5 spikes per second, P .01 ; . The depressed baroreceptor function could be partially restored after a bolus injection of the Na + , K -ATPase inhibitor ouabain 5 J-g kg IV ; . These data indicate that chronic administration of aldosterone decreases baroreflex function without inducing hypertension. An Na + , -ATPase mechanism is involved in this aldosterone-induced depression of baroreceptor function. This mechanism may be involved in the blunting of the baroreflex in heart failure and other hyperaldosteronemic states.

What accounts for its profound beneficial impact? VAN BAKEL Theoretically, the beneficial effect of spironolactone stems from its ability to block the effects of aldosterone. Spironolactobe may also help modulate the extracellular matrix and decrease cardiac fibrosis. ADVISORY BOARD In what situations would you favor the use of phosphodiesterase III inhibitors, such as milrinone, over -adrenergic agonists, such as dobutamine, which have traditionally been used as inotropic agents? VAN BAKEL I can think of 3 or scenarios in which milrinone might be favored. First, milrinone is a better pulmonary vasodilator than dobutamine, thus you would get more bang for your buck by using milrinone in a patient with both right and left heart failure and pulmonary hypertension. Second, in the CHF patient who has been stabilized on a blocker at a moderate to high dose and is admitted with decompensated CHF, milrinone would actually work faster than dobutamine since you have to use much higher doses of dobutamine to overcome the antagonism of the -receptor. Finally, studies have shown that milrinone in particular does not really increase myocardial oxygen consumption. So if you have someone with severe coronary disease in whom you are worried that dobutamine may provoke angina, milrinone might be a better first-line drug. In addition, I've also had occasion to use milrinone in patients who have become refractory to dobutamine, and the combination of low-dose dobutamine and milrinone seems to work a lot better in patients with refractory CHF. In patients with primary aldosteronism, administration of spironolactone 100 - 300 mg daily for 3 - 6 weeks ; is usually associated with a significant reduction in blood pressure, mild weight loss, and normalisation of serum potassium concentration. Sometimes referred to as "triple therapy": vasodilators especially ACE inhibitors, which can lead to 23% relative reduction in mortality 18 beta-blockers which can lead to a 35% relative reduction in mortality 19 and spironolactone which can lead to a 30% relative reduction in mortality ; .20 Sequence of Medication Titration Initially, diuretic agents and vasodilators should be used to stabilize the condition of patients with heart failure Figure 3 ; .11 ACE inhibitors are the vasodilators preferred on the basis of multiple clinical trials that showed mortality benefit.19 Use of angiotensin receptor blockers is an alternative for patients who have intolerance to ACE inhibitors eg, because these patients have cough, angioedema, or allergy ; . Patients with renal dysfunction or hyperkalemia should be treated with hydralazine and isosorbide dinitrate. After the patient's condition has stabilized, a regimen of beta-blockers is added. Beta-blockers may initially worsen heart failure and therefore must be initiated at a low dose. Spironolactone Usual maintenance dose 25 mg daily. Monitor for hyperkalaemia. Observe male patients for tender gynaecomastia. Eplerenone is an alternative if gynaecomastia develops licensed for post MI heart failure only.

Sir, Hepatic hydrothorax complicates advanced liver cirrhosis resulting from the transfer of ascitic fluid into the pleural space in the absence of primary cardiopulmonary disease and, occasionally, of clinically evident ascites. When management with sodium restriction and diuretics fails and repeated thoracenteses are needed, potentially dangerous invasive procedures, such as pleurodesis, thoracoscopic repair of diaphragmatic defects with pleural sclerosis or transjugular intrahepatic portosystemic shunting should be considered [1]. Recently, octreotide-induced natriuresis and reduction of hepatic hydrothorax was described [2, 3]. We report on a case of hepatic hydrothorax, which resolved after adding the a-adrenergic agonist midodrine to octreotide. A large sterile right hepatic hydrothorax was diagnosed in a 66-year-old female with hepatitis C virus HCV ; cirrhosis Child class C ; with mild ascites and deteriorating dyspnoea. Increasing doses of spironolactone and furosemide induced marked hyponatraemia and encephalopathy without a reduction of the pleural effusion, and repeated paracenteses were required. Diuretics were discontinued and octreotide 600 mg day was commenced on day 1; mean arterial pressure MAP ; was 80 mmHg, cardiac output CO ; 7.32 l min, serum urea Ure ; 7.6 mmol l, serum creatinine Cre ; 88.4 mmol l, serum sodium Na ; 124 mmol l, urinary sodium UNa ; 16 mmol day, urinary volume UV ; 1100 ml day, glomerular filtration rate GFR ; with Tc99m-DTPA 112 ml min, effective renal plasma flow ERPF ; with Tc99m-MAG3 615 ml min, plasma active renin PAR ; 119 mU ml, plasma aldosterone PA ; 82.5 ng dl, plasma antidiuretic hormone ADH.
