Methotrexate in the management of severe steroid dependent asthma

AIMS: This study was designed to assess the efficacy of low dose methotrexate, 15 mg weekly, as a steroid-sparing agent in asthmatic patients requiring long-term oral prednisone treatment. METHODS: The study was a randomised, double blind, placebo controlled, cross over study of 48 weeks duration. Eleven patients with severe steroid-dependent asthma were included. A successful outcome was defined as a reduction in mean prednisone requirements of 7 mg daily compared to baseline requirements, during active treatment. RESULTS: Two patients were required to be withdrawn owing to methotrexate-related adverse effects. The mean prednisone dose for patients who completed the study was 14.4 mg per day (95% CI; 13.6, 15.1) during active treatment, and 12.9 mg per day (95% CI: 12.2, 13.6) during placebo treatment (NS). Only one patient reduced his individual dose requirements by more than 7 mg per day, whereas in three patients prednisone requirements actually increased during active treatment. There were no significant differences in symptom scores, pulmonary function data, and exacerbations between active and placebo treatments. CONCLUSION: No significant steroid-sparing effect was obtained using low dose methotrexate in this study. This negative outcome may be attributable to the small population of patients studied, low baseline FEV1, and the omission of a steroid minimisation run-in period. Our results highlight the importance of careful patient selection and a painstaking approach in the management of patients with steroid-dependent asthma.     

Immunosuppressive agents in Horton's disease. Which drug for which indication?

Corticosteroids remain the cornerstone treatment of giant cell arteritis. Steroid-related toxicity and needs for alternative therapeutic regimens in patients experiencing recurrent active or steroid-resistant diseases, are the main reasons for searching a steroid-sparing agent. Regarding disease pathogenesis, immunosuppressive agents might be useful drugs. Methotrexate is the most widely studied agent in this indication. However, available data are incomplete and studies have included only polymyalgia rheumatica or both polymyalgia rheumatica and giant cell arteritis affected patients. Results of these studies evoke the possibility of using methotrexate in steroid-dependent or resistant diseases, as well as a steroid-sparing agent in order to taper off and stop steroids quickly; with an acceptable toxicity. Azathioprine may be used to control steroid-dependant or resistant diseases, but toxicity appears to be higher. An open prospective study compared azathioprine and methotrexate and concluded to the superiority of methotrexate. Available data concerning cyclophosphamide and cyclosporine A are too incomplete. A satisfactory steroid-sparing agent in giant cell arteritis is still unknown. Currently, methotrexate, and probably azathioprine, appear to be the most useful agents in this indication. However, there is no demonstration that using an immunosuppressive agent in giant cell arteritis could reduce steroid-related morbidity.     

A randomized, placebo-controlled trial of topical cyclosporin A in steroid-dependent atopic keratoconjunctivitis

OBJECTIVE: This study aimed to investigate the therapeutic effect of topical cyclosporin A (CsA) 2% in maize oil as a steroid-sparing agent in steroid-dependent atopic keratoconjunctivitis. DESIGN: Prospective, randomized, double-masked, placebo-controlled trial. PARTICIPANTS: Twenty-one patients with steroid-dependent atopic keratoconjunctivitis were studied. INTERVENTION: Patients used either topical CsA or vehicle four times daily for 3 months in addition to their usual therapy, and the clinical response was used to taper or stop topical steroids when possible. MAIN OUTCOME MEASURES: Steroid drop usage per week, ability to cease steroid use, scores for symptoms and clinical signs, drop side effects, and overall subjective rating of trial drop by patients and clinician were measured. RESULTS: Cyclosporin A had a greater steroid-sparing effect than did placebo. Nine of 12 CsA patients ceased steroids compared to 1 of 9 placebo patients (P = 0.01), the final steroid use was lower in the CsA group (2.6 +/- 1.4 vs. 27.7 +/- 17.7, P = 0.005), and the mean reduction in steroid use was greater for CsA (85.5 +/- 14.7 vs. 13.9 +/- 16.0, P = 0.005). Clinical signs and symptom scores were reduced to a greater level for CsA. Serious side effects were lid skin maceration in one patient using CsA and an allergic reaction in one placebo patient. Marked blurring of vision after drop instillation was common in both groups, but intense stinging was more common in CsA patients (9/12 vs. 1/9, P = 0.01), limiting frequency of drop use. The clinician rated the trial drops as good or excellent more frequently for CsA (11/12 vs. 0/9, P < 0.0001). CONCLUSIONS: Topical CsA is an effective and safe steroid-sparing agent in atopic keratoconjunctivitis and, despite difficulties in patient tolerance, also improves symptoms and signs.     

Benefits of high-dose i.v. immunoglobulin in patients with severe steroid-dependent asthma

STUDY OBJECTIVE: To determine the efficacy of IV immunoglobulin (IVIg) in severe asthma to reduce steroid requirements. DESIGN: Pre- and posttreatment measurements were analyzed using Dunnett's multiple comparison procedure. SETTING: Hospital clinical research center. PATIENTS: Eleven adolescents and adults with severe, steroid-dependent asthma enrolled over a 14-month period. INTERVENTIONS: IVIg was administered at a dose of 2 g/kg every 4 weeks for a total of seven infusions. MEASUREMENTS AND RESULTS: Steroid requirements, pulmonary function including lung volumes, symptom scores, bone densitometry, and airway reactivity monitored by methacholine challenge were followed over the course of 7 months. A significant decrease in steroid usage was achieved. Despite substantial steroid reduction, the patients demonstrated improvement in their pulmonary function and symptom scores. The responses to methacholine challenge were unaffected by IVIg treatment. CONCLUSIONS: IVIg provides a potentially important adjunctive therapy in severe asthma, reducing oral steroid requirements and steroid side effects without deterioration of lung function.     

A prospective comparison of four study designs used in assessing safety and effectiveness of drug therapy in hypertension management

The objective of the study was to compare prospectively the impact of study design on drug therapy safety and effectiveness data obtained in hypertension management. The main study was a randomized controlled clinical trial of four different prospective study designs used in postmarketing assessment involving 1008 primary care practices in nine Canadian provinces. Two thousand nine hundred sixty-four patients with mild to moderate hypertension received an angiotensin converting enzyme (ACE) inhibitor daily for 14 weeks in one of four postmarketing studies--a randomized double-blind clinical trial (RCT) (10 to 40 mg fosinopril daily v 5 to 20 mg enalapril daily), two structured open label trials of 10 to 40 mg fosinopril daily (one with free drugs), or an unstructured open label trial of 10 to 40 mg fosinopril daily. Patient demographic and baseline characteristics, systolic and diastolic blood pressures, adverse events reported, and data quality were recorded as the outcome measures. The results showed that the RCT patients were titrated to higher doses of ACE inhibitor than patients in the open studies, P < .008; patients in the open studies were more likely to receive adjuvant diuretic therapy, P < .008. The decrease in blood pressure was similar for patients in all four studies, mean decrease in systolic BP was between 18 and 20 mm Hg, mean decrease in diastolic BP was between 11 and 13 mm Hg. Fewer patients in the unstructured open trial reported adverse events than patients in the RCT; a 55% relative reduction in reported adverse events (P < .008) was associated with the unstructured trial. There were also fewer drug-related adverse events per patient reported in the unstructured study (17 per 100 patients) than in the other studies (27 to 41 per 100 patients), P < .008. Physician preference for rounding off blood pressure measurements to 0 or 5 occurred most often in the unstructured open trial (P < .008). In conclusion, despite differences in dose titration and in the use of adjuvant therapy, antihypertensive drug therapy effectiveness observed in an RCT may be similar to uncontrolled postmarketing studies. Open trials with scheduled follow-up visits are as effective in detecting severe adverse events as RCT, but postmarketing studies with unstructured schedules of follow-up are insufficient in identifying drug-related adverse events and have poorer quality data.     

Management of steroid-dependent asthma with methotrexate: a meta-analysis of randomized clinical trials

Our objective was to determine whether methotrexate is an effective steroid-sparing agent for patients with severe asthma. Published reports of controlled trials assessing the use of methotrexate in asthma were identified by a search of the MEDLINE, EMBASE, CINAHL, Biological Abstracts on CD, and Current Contents databases. Bibliographies from identified studies and from review articles were manually searched. Published and unpublished reports in any language were identified and assessed for inclusion in the meta-analysis. We selected randomized, double-blind, placebo-controlled trials in which low-dose methotrexate was administered to corticosteroid-dependent asthmatics, and oral steroids were subsequently tapered according to the patients' clinical status. Data were extracted independently by two reviewers. For all eligible trials, the mean reduction in oral corticosteroid dose, the mean change in FEV1, and the standard deviations, were calculated for the treatment and control groups. Data concerning side-effects of therapy were also extracted. Data from 12 studies, reporting on a total of 250 patients, were pooled using a weighted average method, with weights proportional to the inverse of the variance of the treatment effect. Compared to placebo, the use of methotrexate was associated with a pooled 6.0% improvement in FEV1 (95% CI, 1.0-11%) and an 18.2% reduction in oral steroid use (95% CI, 11.7-24.7%). This corresponded to a 3.3 mg day-1 greater reduction in oral steroid use for patients taking methotrexate than for those taking placebo (95% CI, 2.1-4.4 mg day-1). Gastrointestinal complications and transient increases in liver enzymes were more common in patients randomized to methotrexate. Three potentially life-threatening side-effects (two pneumonias and one liver dysfunction) occurred in 159 patients randomized to methotrexate vs. none in those patients on placebo. It was concluded that methotrexate allowed a modest reduction in oral corticosteroid compared to patients receiving placebo. The benefit is relatively small, however, and should be balanced against the potential for side-effects associated with the use of methotrexate.     

Safety and efficacy of hydroxychloroquine as maintenance therapy for rheumatoid arthritis after combination therapy with methotrexate and hydroxychloroquine

OBJECTIVE: To evaluate the ability of hydroxychloroquine sulfate (HCQ) to extend the response to combination therapy with HCQ and methotrexate (MTX) and the safety of longterm HCQ maintenance therapy in patients with active rheumatoid arthritis (RA). METHODS: Two-part study consisting of an open label segment evaluating combination HCQ/MTX therapy followed by a double blind segment evaluating maintenance therapy for a total of 60 weeks. First, all patients were treated with HCQ 400 mg/day and MTX 7.5 to 15 mg/week for 24 weeks. Then, responders were randomized into 3 groups: (1) HCQ with MTX as needed for disease flare (n = 40), (2) HCQ 400 mg/day (n = 41), or (3) placebo with MTX as needed for disease flare (n = 40), each for 36 weeks. RESULTS: Clinical disease and laboratory variables improved significantly during initial combination therapy with HCQ and MTX. After MTX withdrawal, HCQ-containing maintenance regimens delayed the onset of disease flare (p = 0.023). There were no unexpected adverse events at any time or between-group differences in the distribution of adverse events during the double blind segment. CONCLUSION: Combination of HCQ and MTX appeared to be effective and well tolerated for 24 weeks. After withdrawal of MTX, HCQ extended the response seen with combination therapy and was well tolerated for 36 weeks. Initial therapy with HCQ and MTX, followed by maintenance HCQ, may be a useful alternative for the treatment of RA.     

Phase I/II study of a short course of weekly cisplatin in patients with advanced solid tumours

Twenty-five patients with advanced solid tumours were entered in a phase I/II study of six, weekly cycles of cisplatin. Nineteen patients were chemonaive and six were previously treated. The starting dose was 50 mg m-2 week-1. This dose could be escalated without major toxicity to 70 mg m-2 week-1. At a dose of 80 mg m-2 myelosuppression grade 3 occurred as well as grade 1 nephro- and neurotoxicity. The maximum tolerated dose was 85 mg m-2 with dose limiting thrombocytopenia. Hypertonic saline was effective in preventing nephrotoxicity. Ondansetron was a very effective antiemetic in the first weeks of treatment but its efficacy waned later on. Responses were observed in head and neck cancer, melanoma and mesothelioma. At the dose level of 80 mg m-2 the optimal dose intensity was reached. This schedule will be tested further in phase II studies.     

Treatment of rheumatoid arthritis with recombinant human interleukin-1 receptor antagonist

OBJECTIVE: To evaluate the efficacy and safety of interleukin-1 receptor antagonist (IL-1Ra) in patients with rheumatoid arthritis (RA). METHODS: Patients with active and severe RA (disease duration <8 years) were recruited into a 24-week, double-blind, randomized, placebo-controlled, multicenter study. Doses of nonsteroidal antiinflammatory drugs and/or oral corticosteroids (< or =10 mg prednisolone daily) remained constant throughout the study. Any disease-modifying antirheumatic drugs that were being administered were discontinued at least 6 weeks prior to enrollment. Patients were randomized to 1 of 4 treatment groups: placebo or a single, self-administered subcutaneous injection of IL-1Ra at a daily dose of 30 mg, 75 mg, or 150 mg. RESULTS: A total of 472 patients were recruited. At enrollment, the mean age, sex ratio, disease duration, and percentage of patients with rheumatoid factor and erosions were similar in the 4 treatment groups. The clinical parameters of disease activity were similar in each treatment group and were consistent with active and severe RA. At 24 weeks, of the patients who received 150 mg/day IL-1Ra, 43% met the American College of Rheumatology criteria for response (the primary efficacy measure), 44% met the Paulus criteria, and statistically significant improvements were seen in the number of swollen joints, number of tender joints, investigator's assessment of disease activity, patient's assessment of disease activity, pain score on a visual analog scale, duration of morning stiffness, Health Assessment Questionnaire score, C-reactive protein level, and erythrocyte sedimentation rate. In addition, the rate of radiologic progression in the patients receiving IL-1Ra was significantly less than in the placebo group at 24 weeks, as evidenced by the Larsen score and the erosive joint count. IL-1Ra was well tolerated and no serious adverse events were observed. An injection-site reaction was the most frequently observed adverse event, and this resulted in a 5% rate of withdrawal from the study among those receiving IL-1Ra at 150 mg/day. CONCLUSION: This study confirmed both the efficacy and the safety of IL-1Ra in a large cohort of patients with active and severe RA. IL-1Ra is the first biologic agent to demonstrate a beneficial effect on the rate of joint erosion.     

Renal function improves in liver transplant recipients when switched from a calcineurin inhibitor to sirolimus

Sirolimus (Rapamune; Wyeth-Ayerst, Philadelphia, PA) is a newer immunosuppressive drug with no known acute or chronic nephrotoxic effects; however, limited data are available in liver transplant recipients. We prospectively evaluated changes in renal function in liver transplant recipients after conversion from a calcineurin inhibitor to sirolimus monotherapy. We measured serial serum creatinine levels in liver transplant recipients with chronic nephrotoxicity caused by calcineurin inhibitors before and after conversion to sirolimus therapy. Estimated glomerular filtration rate (eGFR) was calculated from the Modification of Diet in Renal Disease formula. Change in eGFR over time, incidence of acute hepatocellular rejection, and adverse events while being administered sirolimus monotherapy were recorded. Mean interval between liver transplantation and initiation of sirolimus therapy was 310 weeks (range, 9 to 780 weeks). Of 21 patients included in our study, 18 patients were converted to sirolimus monotherapy and 3 patients were switched to sirolimus and low-dose steroid therapy. Patients were followed up for a mean of 66.8 +/- 38.9 (SD) weeks after conversion. Renal function improved in 71% of patients (15 of 21 patients). Median eGFR improved significantly from 34 mL/min/1.73 m2 at the time of conversion to 43 mL/min/1.73 m2 at the last follow-up (27% increase in eGFR; P = 001). Median monthly change in eGFR was from -0.25 mL/min/1.73 m2 pre-sirolimus therapy to +1.28 mL/min/1.73 m2 post-sirolimus therapy (P =.09). Adverse events were mostly mild and self-limited. Only 1 patient developed biopsy-proven acute cellular rejection, which was treated with sirolimus and mycophenolate mofetil. Two patients discontinued sirolimus therapy because of toxicity (oral ulceration, 1 patient; interstitial pneumonitis, 1 patient). Renal function improved significantly in the majority of liver transplant recipients with renal insufficiency caused by calcineurin inhibitors when converted to sirolimus therapy. Sirolimus monotherapy provided adequate immunosuppression with a low incidence of acute cellular rejection and minimal adverse events.     

A guinea pig''s view on prostate cancer screening trials

Although the combination of paclitaxel with doxorubicin has yielded high response rates in metastatic breast cancer, severe cardiotoxic events have been reported in several patients. The rationale for our study was to evaluate the activity of paclitaxel/doxorubicin combination in patients with this disease but to avoid excessive cardiotoxicity. Therefore, we administered 4 cycles of doxorubicin/paclitaxel followed by 6 cycles of standard cyclophosphamide, methotrexate and 5-fluorouracil (CMF) regimen. Study medication consisted of doxorubicin 60 mg/m2 as a 15-min intravenous infusion followed by paclitaxel 175 mg/m2 as a 3-hour infusion. CMF regimen consisted of cyclophosphamide 600 mg/m2 as 1-hour intravenous infusion followed by methotrexate 40 mg/m2 and 5-fluorouracil 600 mg/m2 bolus injection. The main toxicity of doxorubicin/paclitaxel treatment phase was neutropenia (WHO grade 3/4, 58%), but we observed only one cardiac adverse event. Toxicities of the CMF treatment phase were not significant. Of 24 patients evaluable for response, 2 (8%) had complete responses and 11 (46%) achieved partial response. Ten additional patients (42%) had stable disease. The median time to progression was 12 months and the median overall survival was 18.5 months. The sequential administration of doxorubicin and paclitaxel followed by CMF appeared active and well tolerated in patients with metastatic breast cancer.     

Parkinson's disease: improved function with GM1 ganglioside treatment in a randomized placebo-controlled study

BACKGROUND/OBJECTIVE: Studies in animal models of Parkinson's disease (PD) suggest that GM1 ganglioside treatment can restore neurologic and dopaminergic function. In view of positive preclinical findings and the results of a previous open-label study demonstrating efficacy of GM1 in PD patients, this study compared effects of GM1 ganglioside and placebo on motor functions in PD patients. METHODS: Forty-five patients with mild to moderate PD were studied. The primary efficacy measure was change in the Unified Parkinson's Disease Rating Scale (UPDRS) motor score. After three independent baseline assessments, patients received IV infusion of the test drug (1,000 mg GM1 or placebo) and then self-administered either GM1 or placebo twice daily (200 mg/day, subcutaneously) for 16 weeks. Patients were examined during monthly follow-up visits. RESULTS: There was a significant difference between groups in UPDRS motor scores at 16 weeks (p=0.0001). The activities of daily living portion of the UPDRS (off-period assessment) also showed a significant effect in favor of the GM1-treated patients (p=0.04). GM1-treated patients also had significantly greater mean improvements than placebo-treated patients in performance of timed motor tests including tests of arm, hand, and foot movements, and walking. GM1 was well tolerated and no serious adverse events were reported. CONCLUSIONS: This study demonstrates that GM1 ganglioside treatment enhances neurologic function significantly in PD patients. Further study is warranted to evaluate long-term effects of GM1 in PD patients and to elucidate further the mechanisms underlying patient improvements.     

The acute and chronic effect of oxprenolol and propranolol on peripheral blood flow in hypertensive patients

1 The effects of oxprenolol and propranolol on peripheral blood flow were compared in patients with mild and moderate essential hypertension. 2 In an acute double-blind crossover study in which eight patients participated there was a significant reduction in resting forearm blood flow (RFBF) 2 h after 80 mg propranolol (mean +/- s.e. mean) (-0.87 +/- 0.13 microliter min-1 100 g-1) and after 80 mg oxprenolol (-0.30 +/- 0.12) but not after placebo. This reduction was significantly greater after propranolol (P = 0.022). 3 Seven patients continued into a double-blind crossover study comparing the above dose of the two drugs twice a day. On both the beta-adrenoceptor blockers there was a significant reduction in blood pressure after 2 weeks of treatment and also a significant reduction in RFBF. 4 After 6 weeks treatment with propranolol the reduction in RFBF persisted and was significantly less (P = 0.04) than after 6 weeks treatment of oxprenolol, at which time RFBF was back to control. 5 There were no consistent changes in skin temperature. 6 Neither propranolol nor oxprenolol should be used in patients with severe peripheral vascular disease. 7 If beta-adrenoceptor blockade is necessary in patients with mild peripheral vascular disease oxprenolol should be used in preference to propranolol but should be prescribed with caution.     

Pulse therapy with prospidin and methotrexate: comparative efficacy in rheumatoid arthritis (12-month controlled study)

Efficiency of pulse-therapy with prospidin (500 mg for 5 days in hospital, 500-1000 mg for a month as maintenance) and methotrexate (30 mg a week i.v. in hospital, 7-10 mg a week as maintenance) was investigated in 93 patients with severe RA. The response to prospidin and methotrexate arose quickly (within 10-14 and 4-5 weeks, respectively) and occurred in 73 and 70% of patients, respectively. Withdrawal of the drug was caused by side effects of methotrexate (19.3%) and resistance to prospidin (23.2%).     

"Remembrance and reflection"

Takayasu's arteritis (TA) is a chronic inflammatory arteriopathy affecting the large vessels and has been described predominantly in young adult women. In children it presents as an aggressive disease usually requiring chronic corticosteroid therapy. At present, low dose oral methotrexate (MTX) appears to be an effective steroid-sparing agent in adult patients with active TA. We report a 4-year-old child with Takayasu's arteritis who was initially placed on oral prednisone (2 mg/kg/day) therapy. Three months later, low-dose oral MTX (10 mg/m2/week) was added. Prednisone was successfully tapered over the following year to 0.2 mg/kg every other day. A repeat angiography following 12 months of therapy revealed a dramatic improvement of the vascular lesions. No toxicity was observed with MTX therapy. In conclusion, low-dose oral MTX appeared to be an efficient, safe and steroid-sparing agent in the treatment of a young child with TA.     

Naratriptan is effective and well tolerated in the acute treatment of migraine. Results of a double-blind, placebo-controlled, crossover study. The Naratriptan S2WA3003 Study Group

The efficacy and tolerability of naratriptan tablets (2.5 mg, 1 mg, and 0.25 mg) compared with placebo in the acute treatment of migraine were evaluated in a randomized, double-blind, four-period crossover study. Five hundred eighty-six assessable patients received naratriptan 2.5 mg, 595 received 1 mg, 591 received 0.25 mg, 602 received placebo. Headache relief (moderate or severe pain reduced to mild or none) 4 hours postdose was reported in 68% of patients after treatment with naratriptan 2.5 mg compared with 57% after 1 mg, 39% after 0.25 mg, and 33% after placebo (p < 0.001 naratriptan 2.5 mg and 1 mg versus placebo and 1 mg and 2.5 mg versus 0.25 mg). Headache relief was maintained 8, 12, and 24 hours postdose with no use of rescue medication or a second dose of study medication by significantly (p < 0.001) greater percentages of patients after treatment with naratriptan 2.5 mg or 1 mg compared with naratriptan 0.25 mg or placebo. Naratriptan was also more effective than placebo in reducing clinical disability and the incidences of nausea, photophobia, and phonophobia. The overall incidence of adverse events and the incidences of specific adverse events did not differ in the naratriptan groups compared with placebo. No clinically relevant changes in ECG, blood pressure, or laboratory findings were reported. These data demonstrate that naratriptan is effective and well tolerated for the acute treatment of migraine. The 2.5-mg dose was associated with superior efficacy, whereas its adverse event profile was similar to that of placebo.     

A second phase III multicenter placebo controlled study of 2 dosages of modified release tamsulosin in patients with symptoms of benign prostatic hyperplasia. United States 93-01 Study Group

PURPOSE: In a double-blind, phase III clinical trial we evaluate the safety and efficacy of 0.4 and 0.8 mg. tamsulosin daily for the treatment of patients with symptoms of moderate to severe benign prostatic hyperplasia. MATERIALS AND METHODS: Patients meeting the basic requirements of the study underwent a 4-week single-blind placebo evaluation period. A total of 735 patients were randomized to double-blind therapy with tamsulosin or placebo. Treatment duration was 13 weeks. Efficacy and safety were evaluated at 5 visits during the double-blind treatment period. RESULTS: When efficacy data between baseline and end point were compared there was a significant reduction in total American Urological Association symptom score (25%) in each tamsulosin group compared with placebo (p = 0.01) and the percentage of patients with a 30% or more reduction in peak urinary flow rate was significantly greater in the tamsulosin versus placebo group (p <0.05). Improvements in American Urological Association symptom scores and maximum flow rate occurred at 1 week of treatment. None of the patients experienced a first dose effect. There were no significant changes in blood pressure on standing at any visit during the study except for a decrease in systolic blood pressure of 20 mm. Hg or more between the 0.8 mg. dose and placebo groups at visit 4 (p = 0.036). Positive orthostatic tests were significantly more frequent in the 0.8 mg. group compared with placebo at visit 4 (p = 0.012). The treatment groups did not differ significantly in incidence of electrocardiogram abnormalities at each post-baseline visit and at end point. CONCLUSIONS: Tamsulosin was safe and effective, and clinically and statistically superior to placebo in relieving symptoms of benign prostatic hyperplasia in men with moderate to severe symptoms at baseline. There was no evidence of a first dose effect and no clinically significant orthostatic hypertension. In addition, response to treatment was rapid.     

Methotrexate treatment of idiopathic granulomatous hepatitis

OBJECTIVE: To test the efficacy and safety of low-dose oral pulse methotrexate therapy in patients with idiopathic granulomatous hepatitis who had complications of, did not respond to, or refused glucocorticoid therapy. DESIGN: Prospective case study. SETTING: Academic medical center hospital. PATIENTS: Seven patients with biopsy-proven, idiopathic granulomatous hepatitis who could not tolerate or were unresponsive to glucocorticoid therapy. INTERVENTION: Low-dose oral pulse methotrexate, 15 mg/wk. MEASUREMENTS: Temperature, symptoms, dose of concurrent glucocorticoids, biochemical tests of liver function, side effects of methotrexate, and assessment of liver biopsy specimens. RESULTS: All six febrile patients became afebrile within 3 months of starting methotrexate. Fatigue and anorexia improved in all patients. Glucocorticoid therapy was successfully discontinued within 6 months of starting methotrexate in four patients receiving prednisone at entry. Liver biopsy specimens were obtained again after methotrexate therapy and showed absence of granulomas in four of four patients. The minimum effective dose of methotrexate was 0.20 mg/kg body weight per week. No serious adverse effects and no failures to respond to methotrexate therapy were noted in this group of patients. In three patients, methotrexate therapy has been successfully tapered without signs or symptoms of recurrent disease. CONCLUSIONS: Low-dose oral pulse methotrexate was effective in treating patients with granulomatous hepatitis.     

Treatment of nocturnal asthma with nedocromil sodium

BACKGROUND: The association of nocturnal asthma symptoms with a diurnal increase in inflammatory activity suggests a role for anti-inflammatory therapy in nocturnal asthma. METHODS: Fifty patients with asthma with nocturnal symptoms entered a randomised, double blind, placebo controlled, crossover study. After a two week baseline period patients received nedocromil sodium (4 mg) or placebo four times daily. After eight weeks of treatment patients crossed to the alternative treatment for a further eight weeks. Symptom severity was recorded on a scale of 0-4 and inhaled bronchodilator use and peak flow (PEFR) were also recorded daily by the patients. Asthma severity, pulmonary function (FEV1, PEFR, FVC), and adverse events were recorded at clinic visits (baseline and after four and eight weeks of treatment). Global effectiveness was rated by clinician and patient, and treatment preference was recorded. RESULTS: Efficacy was assessed from data from 28 patients. Night-time asthma (mean (SE) difference between nedocromil sodium and placebo: -0.52 (0.13)), total nocturnal symptom severity defined as night-time asthma plus morning tightness (-0.72 (0.20)), and night-time bronchodilator use (-0.62 (0.23)) were reduced with nedocromil sodium compared with placebo treatment during the primary efficacy period (weeks 5-8) and during weeks 1-4 (-0.36 (0.12), -0.63 (0.20), and -0.55 (0.28), respectively). Morning and evening PEFR values improved slightly--but not significantly--compared with placebo. Patient and clinician opinions favoured nedocromil sodium treatment. Daytime asthma, daytime cough, and clinic assessment of asthma severity (secondary efficacy variables) were improved with nedocromil sodium treatment; day-time bronchodilator use and clinic pulmonary function were not. CONCLUSIONS: Nedocromil sodium was more effective than placebo in reducing nocturnal symptoms of asthma and bronchodilator use in this group of patients.     

Incidence and prevalence of different uveitis entities in Finland

A prospective, open, multicentre study was performed to investigate the efficacy and safety of long-term treatment with cyclosporin in adults with severe atopic dermatitis. Subjects were treated for a maximum of 48 weeks. For the first 8 weeks, cyclosporin was administered at 2.5 mg/kg per day. The dose was then adjusted according to response. Disease activity was monitored using the six-area, six-sign score and the proportion of skin involved. Pruritus and sleep disturbance were assessed using four-point scales. Response was further evaluated on a five-point scale. Adverse events, blood pressure and serum biochemistry were monitored. Tolerability was assessed on a five-point scale. One hundred subjects were enrolled and 65 completed 48 weeks of treatment. Withdrawals occurred due to remission (three), inadequate response (seven), protocol violations (11) and adverse events (14, of which seven were probably treatment related). Cyclosporin produced rapid and highly significant improvements in all indices of disease activity. Sixty-five subjects considered that they had shown a considerable improvement or complete clearance of disease. Most patients relapsed after cessation of treatment, but neither signs nor symptoms had returned to baseline severity 8 weeks later. Blood pressure and serum creatinine levels increased slightly, and in one subject renal impairment was a major factor contributing to withdrawal of the drug. Overall, 85 subjects rated the tolerability of cyclosporin as good or very good. The results indicate that cyclosporin has a place in the long-term treatment of severe atopic dermatitis provided that appropriate patients are selected and careful monitoring is performed.
