Efficacy of nebulized flunisolide combined with salbutamol and ipratropium bromide in stable patients with moderate-to-severe chronic obstructive pulmonary disease.

BACKGROUND: The efficacy of nebulized corticosteroids in the prevention of exacerbation of chronic obstructive pulmonary disease (COPD) has been poorly studied. OBJECTIVE: To evaluate the efficacy and tolerability of nebulized flunisolide (1 mg) + salbutamol/ipratropium bromide (1,875/375 microg) b.i.d. in comparison with placebo + salbutamol/ipratropium bromide. METHODS: This was a randomized, parallel-group, double-blind study on 114 patients with COPD of moderate-to-severe degree. The main outcome was the frequency of severe exacerbations over a 6-month period. Before and after treatment, respiratory symptoms, forced expiratory volume in 1 s (FEV(1)), shuttle walking test distance and St. George's Respiratory Questionnaire scores were evaluated. RESULTS: The total number of exacerbations was slightly lower in the flunisolide group compared to the placebo group (19 vs. 34, p = 0.054); the number of patients experiencing at least one exacerbation during the study was also decreased (16 vs. 26, p = 0.059). In particular, type 3 Anthonisens's exacerbations were significantly reduced by flunisolide (p = 0.044). In the placebo group, scores were higher than in the flunisolide group but nonsignificant for dyspnea, cough, sputum amount and purulence. FEV(1) was significantly increased compared to baseline in both groups, and the area under the FEV(1)-time curve during the 6-month period was significantly greater in the flunisolide group (5.2 +/- 10.6 vs. 2.1 +/- 5.0, flunisolide vs. placebo, respectively; p = 0.047). For shuttle walking test distance and scores of the St. George's Respiratory Questionnaire, no significant difference between the baseline evaluation and the end of the study was observed in both groups. CONCLUSIONS: Nebulized flunisolide is a good alternative to other inhaled corticosteroids when added to nebulized salbutamol/ipratropium bromide in the long-term treatment of moderate-to-severe COPD patients.

Nocturnal enuresis in the adolescent: a neglected problem.

OBJECTIVE: To assess the features of adolescent bedwetters, as few data are available on enuresis in this age group. PATIENTS AND METHODS: A specific database for adolescents and young adults was created with the collaboration of various specialists (paediatricians, urologists, gynaecologists, psychiatrists). Questions focused on family and personal history, stressful events, age of attaining urinary and fecal control, characteristics of enuresis (primary vs secondary, monosymptomatic vs enuresis associated with daytime urinary symptoms), school performance, diagnostic examination and physical examinations, and treatment and its response. RESULTS: Data were collected from 107 enuretic adolescents (mean age 15.3 years, median 14, range 13-23; 63 males and 44 females). A positive family history for enuresis was recorded in 82%. Enuresis was primary in 79 patients (74%), secondary in 28 (26%), monosymptomatic in 76 (71%) and associated with daytime urinary symptoms in 31 (29%). In males monosymptomatic enuresis was significantly more frequent than in females (P < 0.01). Urinary tract infections were reported by 13 patients, all females; eating disorders (anorexia, polyphagia) were present in six. In 85 patients (80%) enuresis was considered severe (> or = three nights/week). Of the 107 patients, 27 (20%) had never consulted a doctor about their problem and 43 (40%) had received no therapy; 66 received desmopressin monotherapy, with a good response (half the number of wet nights) in 44 (79%). There was no relation between response to desmopressin and gender, age, type and severity of enuresis or positive family history of enuresis. Eight patients were provided with a nocturnal alarm but this was not tolerated by two. Altogether, 25 patients refused any therapy or did not comply with the given therapy. CONCLUSIONS: Enuresis can persist into adolescence and be a significant problem; 80% of these patients had severe enuresis and 31% also had associated daytime urinary symptoms, with 40% receiving no previous therapy. The treatment of enuresis can be particularly difficult at this age; 22% of patients did not respond to desmopressin and 23% had low compliance with the given therapy. Enuresis in adolescents requires further study; hopefully more enuretic children will receive adequate treatment before reaching adolescence.

Effectiveness and acceptability of a domiciliary multidrug inhalation treatment in elderly patients with chronic airflow obstruction: metered dose inhaler versus jet nebulizer.

The aim of this study was to compare the immediate and long-term bronchodilator effect as well as the patient acceptability of a 2-week, multidrug, inhalation treatment delivered by a metered dose inhaler (MDI) versus a jet nebulizer in a group of elderly patients with chronic obstructive pulmonary disease (COPD) or asthma and an at least partially reversible airflow obstruction. Twenty elderly outpatients (17 men; mean +/- SD age, 67 +/- 2 years; mean +/- SD baseline forced expiratory volume in 1 second [FEV1], 46.5 +/- 14% of predicted value) with COPD or asthma participated in the study, which was of an open, randomized, crossover design. After a 1-day baseline evaluation, including patient history, clinical examination, and spirometry, participants were randomly assigned to receive a multidrug inhalation treatment (a combination of salbutamol, ipratropium, and flunisolide) with either an MDI or a jet nebulizer. Two weeks later, they were shifted to treatment with the alternative system for a further 2 weeks. FEV1 was measured on the first and fourteenth days of each treatment period, on each occasion both before and 30 minutes after the morning inhalation. At the end of the study, patients were asked to express a personal preference for one of the two inhalation treatments with regard to effectiveness and acceptability by filling out a simple questionnaire. Both the MDI and jet nebulizer had a significant immediate bronchodilator effect on the first and fourteenth days of treatment, with no differences between treatments. No long-term bronchodilator effect was seen with either aerosol delivery system. Patient preferences were clearly in favor of the jet nebulizer with regard to effectiveness and in favor of the MDI with regard to acceptability. In conclusion, in elderly patients with COPD or asthma and partially reversible airflow obstruction, a maintenance multidrug bronchodilator/anti-inflammatory inhalation treatment produced a statistically significant and clinically relevant bronchodilator effect without substantial differences between the two delivery systems. Most patients considered the MDI to be more acceptable and the jet nebulizer to be more effective. These preferences should be taken into consideration when prescribing a maintenance aerosol inhalation treatment.

Italian multicentre open trial on DDAVP spray in nocturnal enuresis.

OBJECTIVE: The aim of the study was to compare the efficacy and safety of different doses of DDAVP spray treatment (20 to 40 mcg/day) in patients with primary monosymptomatic nocturnal enuresis (defined as three or more wet nights per week). MATERIAL AND METHODS: 237 patients (152 males, 75 females; age range 5-17 years), with no infections or organic abnormalities of the urinary apparatus and no neurological disorders, were admitted into the trial. The experimental design was planned as an "open study" with five different treatments schedules (5 groups). The daily doses of DDAVP at bedtime in groups 1 and 2 were 20 and 30 mcg, respectively, for 6 weeks. In groups 3 and 4 the daily doses for the first 2 weeks were 20 and 30 mcg, respectively, and then, after a washout period of 2 weeks, the daily doses for the two groups were 30 and 20 mcg, respectively. A dose-response study (20 to 40 mcg/day) was carried out in group 5. RESULTS: DDAVP spray therapy in primary monosymptomatic nocturnal enuresis was found to be resolutive in 70-75% of treated patients. No difference in response was found between the patients treated with the daily dose of 20 and those on 30 mcg. No important reactions were observed in patients treated with DDAVP spray at the different daily dose (20 to 40 mcg) or for different periods of time (up to 6 weeks). CONCLUSIONS: DDAVP spray therapy at a dose of 20 mcg/day was effective in 70-75% of primary monosymptomatic nocturnal enuretics. In non-responders the daily dose of DDAVP should be increased to 30 to 40 mcg.

[The topical therapy of ulcerative colitis. A multicenter study with beclomethasone dipropionate foam].

BACKGROUND AND AIMS: The use of steroids was recently extended to the various forms of ulcerative rectocolitis by the introduction of topical formulations, above all steroids with an hepatic "first pass" devoid of systemic interference. The aim of this study was to evaluate the efficacy and tolerability of Beclomethasone dipropionate (BDP) in a rectal foam formulation, in the treatment of patients suffering from ulcerative colitis. METHODS: The experimental protocol took the form of a 28-day open prospective trial using BDP rectal foam in patients suffering from ulcerative colitis. Endoscopic, histological, clinical and tolerability parameters were evaluated. The centres taking part in the trial collected data for 60 cases out of a total of 80 patients enrolled in the study, of both sexes and aged between 20 and 81 years old, suffering from proctosigmoiditis (46.7%) and ulcerative rectocolitis (53.3%). RESULTS: Endoscopic parameters showed an improvement after 28 days of treatment in 74.5% of patients; a clinical improvement was achieved in 65.2% of cases. In percentage terms of the mean value of all the improved parameters, histological parameters were altered in 56.9% of patients. With regard to tolerability 82% of patients judged the treatment to be good/excellent. CONCLUSIONS: In conclusion, in line with recent reports regarding other pharmaceutical forms of BDP, including the use of rectal foam, these data confirm the efficacy and tolerability of this molecule and emphasise the validity of its use in the treatment of ulcerative colitis and proctosigmoiditis.

[Topical beclomethasone dipropionate (BDP) in intestinal inflammatory diseases: the results of a multicentre trial].

The authors assessed the efficacy and tolerability of BDP in an open protocol using rectal enemas and suppositories and in a double-blind protocol vs mesalazine using rectal enemas. A total of 47 patients suffering from ulcerous rectocolitis were enrolled in the study and treated for 42 days while undergoing endoscopic, histologic and clinical controls. In conclusion, the authors affirm that BDP may represent a useful new therapeutic instrument in the treatment of slight to moderately severe forms of inflammatory intestinal disease.

Evaluation of antidiuretic hormone before and after long-term treatment with desmopressin in a group of enuretic children.

OBJECTIVE: To determine the effect of long-term desmopressin therapy in enuretic patients on the levels of antidiuretic hormone (ADH) during and after the end of therapy. PATIENTS AND METHODS: The study comprised 25 outpatients (18 boys and seven girls) aged 8-12 years at the start of therapy and 12-16 years at the end. The morning (08.00 hours) plasma ADH level was determined before treatment (T0) with desmopressin and 2 years after (T1) ending the therapy. Seven of the 25 patients evaluated had monosymptomatic (simple enuresis, SE) and 18 had other symptoms (complex enuresis, CE). RESULTS: In the patients with SE, the mean (SD) duration of therapy was 305 (183) days and they were reevaluated 2.5 (0.67) years later. Of 18 patients with CE, eight were treated only with desmopressin for 204 (117) days. In 10 with an incomplete response after 30 days with only desmopressin, oxybutynin (5 mg twice daily) was added; the duration of their therapy was 255 (152) days and they were re-evaluated 3.9 (0.6) years later. The mean (SD) ADH level in those with SE and CE was 2.14 (0.93) ng/L and 2.53 (1.16) ng/L), respectively, both significantly lower (P < 0.001) than in controls, at 5.1 (1.6) ng/L. On re-evaluation at T1, there was a significant (P < 0.001) increase in ADH levels over those at T0 in both groups, at 5.2 (0.8) and 5.3 (1.9) ng/L, respectively. CONCLUSION: These results seem to confirm the role played by ADH in the pathophysiology of enuresis.

Nocturnal enuresis and daytime wetting: a multicentric trial with oxybutynin and desmopressin.

OBJECTIVE: Different etiopathological mechanisms of enuresis are today under study, and different therapies and drugs have been proposed. The Italian Multicentric Trial was undertaken in twelve pediatric and urological centers in order to assess the efficacy of two of the most popular drugs, desmopressin (DDAVP) and oxybutynin. METHODS: 114 enuretic patients were enrolled in the study. After a 2-week observation period, 66 patients with primary monosymptomatic enuresis were treated with DDAVP, 30 micrograms/day intranasally, for 6 weeks, 48 patients with enuresis and voiding dysfunction were randomly assigned to a protocol with oxybutynin alone or oxybutynin plus DDAVP. The efficacy of the two drugs was measured in terms of reduction of wet nights per week during the 6-week treatment period and a 2-week follow-up period. Children with 0-3 dry nights/week were considered as nonresponders. RESULTS: Patients with monosymptomatic enuresis treated with DDAVP reported a significantly lower number of wet night during treatment than during the baseline period, with 79% showing a 'good' (6-7 dry nights/week) or 'intermediate' response (4-5 dry nights/week). Of the patients with diurnal voiding disturbances and enuresis, those treated with oxybutynin alone had a 54% success rate. The patients treated with both oxybutynin and DDAVP showed a better response, with a 71% rate of success. CONCLUSIONS: The efficacy of the two drugs is confirmed in patients carefully selected on the clinical basis of voiding disturbances. In patients with enuresis and voiding dysfunction, the reduced urinary output and the lower bladder filling rate due to DDAVP can reduce uninhibited bladder contractions, thus enhancing the oxybutynin action.

Platelet plasma membrane in subjects with primary nocturnal enuresis: effect of desmopressin.

Plasma membrane fluidity of platelets (PLT) obtained from subjects with primary nocturnal enuresis (PNE) and healthy controls was investigated before and after addition of desmopressin (DDAVP). Membrane fluidity was studied by measuring steady-state fluorescence anisotropy of 1-(4-trimethylammoniumphenyl)-6-phenyl-1,3, 5-hexatriene incorporated into PLT plasma membrane. Our results show an increase in membrane fluidity at the surface level of PLT from subjects with PNE. Moreover, the addition of DDAVP induces a stable and significant decrease of membrane fluidity in both groups. These results suggest alterations of the lipid order in the exterior part of the PLT plasma membrane from patients with PNE.

[Upper digestive hemorrhage. Comparison of terlipressin and octreotide].

The efficacy and tolerability of both Terlipressin and Octreotide in the treatment of upper digestive haemorrhage (oesophagus, stomach and duodenum) have been compared, at random, on 30 adult patients. Terlipressin dosage was 2 mg/4 hours i.v. during the first 24 hours, 2 mg/6 hours during the following 24 hours. Octreotide dosage was 50 micrograms i.v. and infusional therapy, 25 micrograms/hours, followed. Haemostasis was obtained in 100% of patients treated with Terlipressin and in 73% of patients treated with Octreotide. Rebleeding occurred in 3 patients treated with Terlipressin and 4 patients treated with Octreotide. Side effects occurred in 4 patients treated with Terlipressin and 8 patients treated with Octreotide. Terlipressin proved to have a better efficacy in comparison with Octreotide, and had less side effects.

[Effectiveness of and tolerability to oral desmopressin in the treatment of central diabetes insipidus].

Intranasal desmopressin represents the treatment of choice in Central Diabetes Insipidus. Nevertheless, this route of administration bears some practical disadvantage, linked to either difficult delivering technique, or the status of nasal mucose. The antidiuretic effectiveness of oral desmopressin has been recently demonstrated, both in experimental animals and in man. In our study we compared oral vs. intranasal desmopressin efficacy in 13 patients affected by Central Diabetes Insipidus. The results show that the peroral administration of Desmopressin at a mean dose of 500-600 micrograms/die determines an antidiuretic effect comparable to that of intranasal route, without affecting body weight, arterial pressure and chemical analysis. Side effects, generally limited to the first week of treatment, were described (nausea, vomiting, headache, dizziness [corrected], bitter taste, epygastralgia, asthenia, epystassis), inducing 4/13 patients to withdrawal the trial.

[Somatostatin in the treatment of acute pancreatitis and prevention of postoperative acute pancreatitis. Personal experience].

Authors' personal experience is reported in the use of somatostatin for the treatment of acute pancreatitis and after bilio-pancreatic surgery. The drug has proved to be highly effective in reducing the pain and in controlling the biohumoral balance. The preliminary results appear to confirm the opinion that somatostatin is a major therapeutic tool in the treatment of bilio-pancreatic diseases.

Effectiveness of calcium antagonist drugs in patients with unstable angina and proven coronary artery disease.

Eighty-five patients admitted to our CCU for unstable angina (UA) with proven coronary artery disease, in whom i.v. therapy with nitroglycerin (N) and heparin (H) did not reduce both painful and painless episodes of myocardial ischaemia, were treated by i.v. administration of verapamil (V) and diltiazem (D) in order to assess the efficacy of calcium antagonists in reducing myocardial ischaemia. All patients were given i.v. N + H throughout the whole study period; none showed significant increase in serum CK MB concentration. V and D were assigned following a double-blind, cross-over, placebo-controlled design after a 48 h period of N + H therapy. Continuous Holter monitoring (CHM) was performed during the whole study period. V and D significantly reduced the total number of ischaemic episodes day-1 (N + H = 6.8 +/- 3.9; D = 2.1 +/- 2.3, P less than 0.001; V = 1.7 +/- 2.7, P less than 0.001), the number of silent episodes (SE) (N + H = 5.2 +/- 3; D = 1.4 +/- 1.4, P less than 0.001; V = 1.5 +/- 2.5, P less than 0.001) and the duration of SE (N + H: 428 min for all patients, D: 61 min, V: 112 min). In patients with UA and proven CAD in whom i.v. N and H are ineffective to control myocardial ischaemia, V and D given i.v. reduced both painful and painless ischaemic episodes and allow safe delay of coronary arteriography and myocardial revascularization without adjunctive risk. Continuous Holter monitoring is important to detect the total ischaemic burden.

[Experimental study on the use of cisplatin in oncology].

29 patients affected by ovarian (9 cases), head and neck, and miscellaneous neoplasms were treated with Cisplatinum. Most cases had been previously treated with different drugs. Complete and partial remission achieved significative results in 4, 7 and 9 ovarian patients. In the patients with head and neck tumor no complete remission and 4 partial remissions were obtained. These observations confirm that Cisplatinum may be a useful drug in chemotherapy of cancer.

Comparison of the effectiveness of several formulations of sodium valproate: tablets, enteric-coated capsules, solutions and rectal capsules.

The effects of an oral enteric-coated preparation (VAL 579 capsules) of sodium valproate (VPA) were compared with those of conventional oral and rectal preparations in 24 epileptic patients. Enteric-coated capsules are useful for avoiding gastric intolerance to VPA. Plasma VPA level peaks after the enteric- coated form were later than after other forms. The bioavailability appeared to be the same for all the forms.
