Growth of asthmatic children during treatment with budesonide: a double blind trial.

OBJECTIVE--To determine whether the inhaled glucocorticosteroid budesonide has any adverse effect on short term linear growth in children with mild asthma. SETTING--Outpatient clinic in secondary referral centre. PATIENTS--15 children aged 6-13 years with normal statural growth velocity during the previous year, no signs of puberty, and no use of systemic or topical steroids in the two months before the study. DESIGN OF INTERVENTIONS--Double blind, randomised crossover trial with two active periods in which budesonide was given in divided daily doses of 200 micrograms and 800 micrograms. During run in and two washout periods placebo was given. After the second washout period the children received open treatment with 400 micrograms budesonide daily. All periods were of 18 days'' duration. MAIN OUTCOME MEASURE--Growth of the lower leg as measured twice a week by knemometry. RESULTS--Mean growth velocity of the lower leg was 0.63 mm/week during run in and during washout 0.64 mm/week. Budesonide treatment was associated with a significant dose related reduction of growth velocity: the mean reduction in growth velocity during treatment was 0.11 (95% confidence interval -0.15 0.36 (0.13 to 0.59) mm/week with 800 micrograms budesonide (p less than 0.05; Page''s test). During treatment with 400 micrograms budesonide a reduction of 0.17 (-0.10 to 0.45) mm/week was found. CONCLUSIONS--Treatment with inhaled budesonide is associated with a dose related suppression of short term linear growth in children with mild asthma.     

Effect of long-term prazosin treatment on certain humoral and metabolic factors in patients with primary hypertension]

An effect of the long-term prazosin therapy on sympathetic activity, renin plasma activity and beta-endorphin and lipid blood levels was investigated in 23 patients with the primary arterial blood hypertension. Group A included 18 patients treated with prazosin, and group B - 5 patients treated with prazosin combined with propranolol. Mean daily dose of prazosin in group A was 3.0-10.0 +/- 1.3 mg in different phases of therapy whereas in group B mean daily dose of prazosin was 3.0-6.5 +/- 1.8 mg and propranolol 50-80 mg. Significant decrease in diastolic and systolic blood pressure (p < 0.01) was achieved in both groups. Additionally significant decrease in pulse rate (p < 0.01) was seen in group B. It was found that prazosin produced significant increase in plasma noradrenaline in group A and decrease in 4-hydroxy-3-methoxyglycol excretion with the urine (p < 0.05) in both groups. Moreover, negative correlation between a decrease in blood pressure (diastolic) and noradrenaline excretion with the urine (p < 0.05) was noted in group A. No effect of prazosin therapy on plasma renin activity, beta-endorphin and lipids blood levels was observed in both groups. These results suggest that prazosin therapy in patients with the primary blood hypertension exerts an effect on sympathetic activity and does not change plasma renin activity or blood beta-endorphin and lipids levels.     

Ampicillin Dosage and Use of Prednisolone in Treatment of Pneumonia: Co-operative Controlled Trial

A controlled trial was carried out to investigate whether the rate of recovery from pneumonia treated with ampicillin is dose related. Sixty-three patients received 1 g ampicillin daily and 63 received 2 g ampicillin daily for seven or 14 days depending on the rate of response. Twenty patients in each of these groups received, in addition, 20 mg prednisolone daily for seven days. The treatment groups were comparable and the results of treatment were similar in the four groups. The only difference which was of statistical significance was that a larger proportion of patients receiving 1 g ampicillin daily became afebrile within one week. All the ampicillin rashes occurred in the patients receiving 2 g ampicillin daily with and without prednisolone. Ampicillin 1 g daily appears to be adequate dosage in the treatment of pneumonia, and the rate of recovery has not been shown to be accelerated by using 2 g. No deleterious effects were noted with additional prednisolone therapy and this appeared to increase the rate at which the patients became afebrile, although the figures were not statistically significant.     

Phase II clinical study of high-dose toremifene in patients with advanced breast cancer

Thirteen postmenopausal women with advanced local or metastatic breast cancer were treated with the antiestrogen toremifene at a daily dose of 200 mg. All patients had failed previous treatment with different types of endocrine therapy and/or cytotoxic drugs. Objective response was only seen in one patient. Treatment was usually well tolerated but in three cases the drug had to be withdrawn due to side effects.     

SYSTEMIC LUPUS ERYTHEMATOSUS—Results of Treatment with Triamcinolone

Twenty-nine patients with systemic lupus erythematosus were treated with a new synthetic unsaturated prednisolone derivative, triamcinolone, for as long as 11 months. This hormone is 1.3 times as powerful as prednisone and 4.4 times more potent than hydrocortisone as an anti-inflammatory agent. The average dose for beginning therapy in cases of mild systemic lupus erythematosus was 20.6 mg. a day. The average maintenance dose used to control mild exacerbations of the disease was 26.0 mg. a day. There was no evidence of sodium retention or potassium loss.Sixteen patients had upper gastrointestinal x-ray studies before and during therapy with triamcinolone. There was no evidence of peptic ulceration except in one patient who was receiving 96 mg. a day. Nine patients had gastric analysis with histamine before and during therapy. No significant changes were noted in results of these tests, even in the patient who had an ulcer. No abnormal increase in uropepsin was noted in cases in which this factor was tested.The pattern of clinical improvement closely paralleled that obtained by previous treatment with older steroids. There was a disappearance of all the clinical and laboratory abnormalities produced by the disease, with the exception of long standing renal involvement. A major difference between triamcinolone and other steroids was a tendency to progressive gradual loss of weight, partly owing to fluid loss. Cushingoid appearance produced by other steroid therapy did not disappear.The cutaneous side effects, particularly Cushingoid appearance, hirsutism and striae were more pronounced than with older steroids. The most serious side effect was muscle weakness which appeared in six patients, all women, in from four to thirty-two weeks after starting triamcinolone. The profound muscle weakness, most pronounced in the quadriceps group, gradually cleared after several weeks of therapy with another steroid.Fourteen patients had received prior steroid therapy with all the older anti-inflammatory hormones and seven of them were better controlled and felt better with triamcinolone.     

Converting-enzyme inhibitor enalapril (MK421) in treatment of hypertension with renal artery stenosis.

Enalapril maleate (MK421), a new inhibitor of angiotensin converting enzyme, in single daily doses of 1.25-40 mg was assessed in five patients with hypertension and renal artery stenosis. Only small falls in plasma angiotensin II concentrations were seen at doses less than 10 mg; even with 10 and 20 mg, angiotensin II concentrations had risen again 24 hours from the last dose. During long-term treatment with 10-40 mg daily all patients achieved good blood-pressure control. No significant changes of body sodium or potassium values were seen. The drug was well tolerated with no serious side effects. These findings are evidence of the efficacy and acceptability of enalapril in the medical management of hypertension with renal artery stenosis.     

Systemic lupus erythematosus; results of treatment with triamcinolone

Twenty-nine patients with systemic lupus erythematosus were treated with a new synthetic unsaturated prednisolone derivative, triamcinolone, for as long as 11 months. This hormone is 1.3 times as powerful as prednisone and 4.4 times more potent than hydrocortisone as an anti-inflammatory agent. The average dose for beginning therapy in cases of mild systemic lupus erythematosus was 20.6 mg. a day. The average maintenance dose used to control mild exacerbations of the disease was 26.0 mg. a day. There was no evidence of sodium retention or potassium loss. Sixteen patients had upper gastrointestinal x-ray studies before and during therapy with triamcinolone. There was no evidence of peptic ulceration except in one patient who was receiving 96 mg. a day. Nine patients had gastric analysis with histamine before and during therapy. No significant changes were noted in results of these tests, even in the patient who had an ulcer. No abnormal increase in uropepsin was noted in cases in which this factor was tested. The pattern of clinical improvement closely paralleled that obtained by previous treatment with older steroids. There was a disappearance of all the clinical and laboratory abnormalities produced by the disease, with the exception of long standing renal involvement. A major difference between triamcinolone and other steroids was a tendency to progressive gradual loss of weight, partly owing to fluid loss.

The most serious side effect was muscle weakness which appeared in six patients, all women, in from four to thirty-two weeks after starting triamcinolone. The profound muscle weakness, most pronounced in the quadriceps group, gradually cleared after several weeks of therapy with another steroid. Fourteen patients had received prior steroid therapy with all the older anti-inflammatory hormones and seven of them were better controlled and felt better with triamcinolone.     

Beclomethasone dipropionate in asthma.

Beclomethasone dipropionate aerosol therapy can replace or diminish systemic corticosteroid therapy in the majority of asthmatics. In a clinical trial of 41 patients with perennial asthma, the 10 who had not required long-term corticosteroid therapy improved symptomatically and in pulmonary function. Of the 31 who had required prolonged systemic corticosteroid therapy 12 were able to discontinue oral prednisone therapy, 15 were able to decrease the maintenance dose of prednisone and only 4 were unable to decrease the dose; all maintained satisfactory lung function and some showed improvement. Discontinuation of systemic corticosteroid therapy was accomplished more readily in patients whose daily maintenance dose was less than 15 mg and who had been taking the drug for less than 3 years. Side effects consisted of a "dry throat" in seven patients, two of whom had throat infections with Candida albicans. Recurrence of rhinitis after discontinuation or reduction of systemic corticosteroid therapy was noted in 11 patients.     

Effect of inhalation therapy with beclomethasone dipropionate on unspecific bronchial hyperreactivity in patients with asthma]

An effect of beclomethasone dipropionate (Beclocort-Polfa) was investigated in the group of 24 patients with atopic and non-atopic bronchial asthma who have shown unspecific bronchial hyperreactivity to histamine during the periods of remission. The drug was administered in the form of aerosol in a daily dose of 1.0 mg for 4 weeks. Provocative histamine dose was established with Bronchoscreen device (Jaeger) thrice:prior to the treatment, after 1 week of placebo therapy, and after 1 month of beclomethasone administration. Statistically significant increase in histamine dose for provocation of bronchospasm (p < 0.01) being nearly twice higher than the baseline value has been noted in patients treated with beclomethasone dipropionate aerosol. It advocates such a treatment in unspecific bronchial hyperreactivity independently of the type of the bronchial asthma.     

Phase I evaluation of coumarin (1,2-benzopyrone) and cimetidine in patients with advanced malignancies.

Fifty-four patients with advanced malignancies were treated on this phase I trial of coumarin and cimetidine. The dose of coumarin was escalated, with three patients treated at each dose level, while the cimetidine dose was held constant at 300 mg four times daily. Patients received coumarin alone as a single daily oral dose for 14 days; on day 15, cimetidine was added and both drugs were continued until progression of disease. This trial was initiated with patients receiving coumarin at 400 mg daily and closed at 7 g daily with four of five patients on this dose experiencing nausea and vomiting. Treatment was generally well tolerated over a wide range of coumarin doses. Symptomatic side effects were few, mild, and usually self limited. Side effects included insomnia, nausea, vomiting, diarrhea, and dizziness. Two patients withdrew from therapy because of daily nausea and vomiting. Typically, nausea, vomiting, and dizziness occurred 2.5-3 hours after a dose of coumarin. In most patients, these side effects abated spontaneously with continuation of therapy. There was no significant hematologic or renal toxicity. Hepatotoxicity occurred in only one patient and was manifested by asymptomatic abnormal elevations of serum hepatic transaminases. This toxicity was reversible upon interruption of therapy. Objective tumor regressions were observed in six patients with renal cell carcinoma. Responses occurred at coumarin doses ranging from 600 mg to 5 g daily. Coumarin is a relatively nontoxic, oral, outpatient therapy that warrants further investigations for the treatment of human malignancies. Because of its low toxicity, there is potential for combining coumarin with chemotherapeutic and/or biological agents in an attempt to improve on efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)     

Therapeutic experience with fludrocortisone in diabetic postural hypotension.

Fourteen patients with diabetic postural hypotension were treated with fludrocortisone for a mean 12 months (range 6-30 months). The mean daily dose of fludrocortisone was 0.2 mg (range 0.1 mg-0.4 mg). Standing systolic and diastolic blood pressures increased significantly (P less than 0.001) after treatment with fludrocortisone and the postural hypotension decreased significantly (P less than 0.001). Thirteen patients noted considerable symptomatic improvement. Fludrocortisone should be used cautiously in patients with congestive cardiac failure or the nephrotic syndrome.     

Androgen therapy in constitutional delay of growth

BACKGROUND/AIMS: Two modalities of androgen therapy prevail in the treatment of constitutional delay of growth (CDG): monthly injections of testosterone or daily tablets of the non-aromatizable oxandrolone. The present study was undertaken to prospectively compare both compounds and dose. METHODS: Thirty patients with CDG were the subjects of this study. The protocol required that they all be at age 12-14 years with a bone age delay of more than 2 'years', height less than -2 SDS and growth velocity less than -0.5 SDS. The subjects were at a Tanner stage 1 or 2 and testicular volume were no larger than 4 ml. They were randomly assigned into 3 treatment groups: group 1 patients received monthly injections of 25 mg testosterone propionate-enanthate; group 2 patients received monthly injections of 50 mg testosterone propionate-enanthate; group 3 patients received oral oxandrolone at a weekly dose of 0.7 mg/kg. Treatment was given for a period of 6 months and follow-up commenced 6 months later and yearly thereafter for 2 years. RESULTS: Height velocity and height increased significantly only in groups 2 and 3. Bone age advanced most in group 2. Puberty progressed faster in that group as compared with group 3. The predicted adult height before and 2 years after completion of treatment remained unchanged in the two testosterone groups. It increased significantly in the oxandrolone group from a mean 169.8 cm before therapy to a mean 177.5 cm 2 years after completion of therapy. Peak GH levels were significantly higher on both testosterone 50 mg and oxandrolone, as compared to pretreatment levels. The increment was significantly greater in group 2 as was the increment in serum IGF-1 and IGFBP3. CONCLUSIONS: These results imply that 6 months of testosterone injections at a dose of 50 mg, but not 25 mg, is an effective and safe treatment for patients with CDG, with no considerable impact on final height prediction. On the other hand, daily oxandrolone treatment, starting at age 12-14 years, may increase the predicted final adult height.     

Controlled trial of budesonide given by the nebuhaler in preschool children with asthma.

OBJECTIVE--To determine whether the inhaled corticosteroid budesonide, given by a Nebuhaler spacing device, was effective in prophylaxis of asthma in preschool children. DESIGN--Double blind, placebo controlled, random order crossover trial with two week practice run in period. SETTING--Outpatient clinic referrals in secondary referral centre. PATIENTS--39 children aged 2-6 years selected for the following: able to use Nebuhaler; parents able to complete record card; poorly controlled asthma (defined); not already on systemic or inhaled steroids. Eleven withdrew for various reasons not connected with intolerance to budesonide. Age, sex, other atopies, and symptoms during run in period were similar in the 28 children who completed the trial and in the 11 who withdrew. INTERVENTIONS--Budesonide 200 micrograms or placebo (both one puff) given twice daily during 6-week treatment or control periods, using Nebuhaler after prior training. Three week "washout" at crossover. Compliance monitored by weighing canisters. Patients withdrawn if their acute attacks required treatment with systemic steroids. END POINT--Control of asthma. MEASUREMENTS AND MAIN RESULTS--Peak expiratory flow rate measured twice daily where cooperation allowed. Diary of symptoms and concomitant drug use kept daily. Results showed mean peak flow significantly higher (12% in mornings, 14% in evenings) in second three weeks of intervention compared with control period (95% confidence intervals 6.3-17.3% and 7.2-21.0%). Supplementary bronchodilator drugs reduced by 50% during intervention periods. CONCLUSIONS--Budesonide given by Nebuhaler is effective prophylaxis for preschool children with frequent asthma.     

Effect of long-term treatment with salmeterol on asthma control: a double blind,randomised crossover study.

OBJECTIVES: To determine the effect of adding salmeterol 50 micrograms twice daily for six months to current treatment in subjects with asthma who control their inhaled corticosteroid dose according to a management plan. DESIGN: A double blind, randomised crossover study. SETTING: Nottingham. SUBJECTS: 101 subjects with mild or moderate asthma taking at least 200 micrograms twice daily of beclomethasone dipropionate or budesonide. INTERVENTIONS: Salmeterol 50 micrograms twice daily and placebo for six months each, with a one month washout. Subjects adjusted inhaled steroid dose according to guidelines. MAIN OUTCOME MEASURE: Reduction in inhaled steroid use, exacerbations of asthma, and use of oral steroids. RESULTS: Data were available for 87 subjects. When compared with placebo salmeterol treatment was associated with a 17% reduction in inhaled steroid use (95% confidence interval 12% to 22%) with no significant difference in the number of subjects who had an exacerbation (placebo 25%, salmeterol 16%) or use of oral steroids. For secondary end points salmeterol treatment was associated with higher morning and evening peak expiratory flow and forced expiratory volume in one second; a reduction in symptoms, bronchodilator use and airway responsiveness to methacholine; and no effect on serum potassium concentration, 24 hour heart rate, or the final forced expiratory volume in one second achieved during a salbutamol dose-response study. CONCLUSIONS: In subjects who adjusted their inhaled steroid treatment according to guidelines the addition of salmeterol 50 micrograms twice daily was associated with a reduction in inhaled steroid use and improved lung function and symptom control.     

Effect of ACE inhibitors on proteinuria and renal functioning in primary glomerulopathies]

Angiotensin converting enzyme inhibitors was given to 16 patients with glomerular nephritis in whom a complete remission of nephrotic syndrome could not be achieved with immunosuppressive-anti-inflammatory therapy. Captopril in the daily dose of 25-75 mg and enalapril in the daily dose of 10 mg were administered for 1-36 months (mean 12.6 months). Daily proteinuria decreased by 40-80% comparing with baseline value in 2/3 of patients. Total protein and albumin serum levels increased simultaneously. No changes in blood creatinine were noted in patients with initially normal renal functioning except one patient. Renal functioning was stable in 50% of patients with increased blood creatinine levels (mean 200 mumol/L). Blood creatinine was increasing in the remaining patients.     

4-Hydroxyandrostenedione treatment for postmenopausal patients with advanced breast cancer

We have treated 128 postmenopausal women with advanced breast cancer with 4-hydroxyandrostenedione. Of these, 118 were assessable for toxicity and 100 for response to treatment. Response to therapy was seen in 34% of patients and stabilization of disease in 12 patients. Three dose regimens were used (500 mg intramuscularly weekly; 250 mg intramuscularly every 2 weeks; and 500 mg orally daily). There was no difference in response in these three groups. Side effects were minimal and local reaction to injected drug was seen in 13% of patients. The sole severe side effect observed was neutropenia which was transient and reversible on discontinuing therapy. 4-Hydroxyandrostenedione is an effective nontoxic agent in the treatment of breast cancer.     

Effect of statin therapy on the progression of coronary atherosclerosis

ABSTRACT: BACKGROUND: An increasing number of authors employing intravascular ultrasound (IVUS) and virtual histology (VH-IVUS) have investigated the effect of statin use on plaque volume (PV) and plaque composition. However, inconsistent results have been reported. Therefore, we conducted a meta-analysis to determine the appropriate regimen of statins to effectively stabilize vulnerable coronary plaques. METHODS: Online electronic databases were carefully searched for all relevant studies. We compared mean values of PV and plaque composition between baseline and follow-up in patients receiving statin therapy. We pooled treatment effects and calculated mean differences (MD) with the 95% confidence interval (CI) using a random-effects model. By stratified analyses, we explored the influence of clinical presentation, dose and duration of statin treatment, and low-density lipoprotein-cholesterol (LDL-C) levels on the effects of statins. RESULTS: Seventeen studies involving 2,171 patients were analyzed. Statin therapy significantly decreased PV (-5.3 mm3; 95% CI: --3.3 mm3 to -7.2 mm3; P < 0.001), without heterogeneity. When considering the dose and duration of statins used, only subgroups employing a high dose and long duration demonstrated a significant reduction in PV (p < 0.001). A significant decrease in PV was noted if achieved LDL-C levels were <100 mg/dL (p < 0.001). Statin treatment could induce a twofold decrease in PV in patients with acute coronary syndrome (ACS) compared with that observed in patients with stable angina pectoris (SAP). A regressive trend was seen for necrotic core volume (MD: --2.1 mm3; 95% CI: --4.7 mm3 to 0.5 mm3, P = 0.11). However, statin use did not induce a significant change for fibrotic, fibro-fatty, or dense calcium compositions. CONCLUSIONS: Our meta-analysis demonstrated that statin therapy (especially that involving a high dose and long duration and achieving <100 mg/dL LDL-C levels) can significantly decrease PV in patients with SAP or ACS. These data suggested that statins can be used to reduce the atheroma burden for secondary prevention by appropriately selecting the statin regimen. No significant change in plaque composition was seen after statin therapy.     

Hydrochlorothiazide, allopurinol and magnesium oxide in the treatment of recurrent calcium urolithiasis]

The study aimed at presenting own experience in prevention of new urinary calculi in 18 patients with metabolically active calcium urolithiasis treated with hydrochlorothiazide in daily doses of 100 mg (group I) for 2 years, and in 6 patients with the same disease treated with magnesium oxide in daily doses 300 mg twice a day (group II) for average period of 10 months. In 9 patients a new calculus was formed during the treatment with hydrochlorothiazide, in 7 patients no recurrence was noted, and in 2 remaining patients the results were controversial (coral calculus). Therefore, patients were subdivided into group Ia (failure of hydrochlorothiazide therapy), and group Ib (no recurrence noted). Hydrochlorothiazide did not lead to the stable decrease in the saturation of the urine with calcium oxalate in group Ia whereas in group Ib (without recurrence of urolithiasis) the content of calcium oxalate in the urine was significantly lower than that in group Ia after a 2-year treatment with hydrochlorothiazide (p < 0.01) Recurrence of the disease was seen only in one patient of group II, i.e. treated with magnesium oxide. The treatment of the recurrent calcium urolithiasis is justified and efficient in those patients in whom therapy decreases the content of calcium oxalate in the urine.     

Chronic treatment of Paget's disease of bone with synthetic human calcitonin.

Twelve patients with Paget''s disease of bone were treated with synthetic human calcitonin for seven to 26 months (mean 15.3 months). This group included six patients who had previous therapy. Eleven of the 12 patients experienced relief of the symptoms associated with Paget''s disease. The initial therapy of synthetic human calcitonin 0.5-1.0 mg subcutaneously was administered daily until the alkaline phosphatase had declined to a plateau response; the dose was then decreased to thrice weekly. The major biochemical findings were a 47 percent fall in serum alkaline phosphatase and a comparable decline in 24-hour urinary hydroxyproline. Two subjects discontinued therapy because of side effects; persistent nausea and vomiting in one and a cutaneous allergic reaction in the other. Other side effects were minor. Preliminary results suggest that some patients will maintain the same biochemical response on the reduced dose but that this is not predictable by pre-treatment data. We conclude that synthetic human calcitonin is a safe and effective treatment for Paget''s disease of bone. Preliminary results suggest that the dose and frequency of administration of this agent must be individualized.
