Treatment of chronic depression with sulpiride: evidence of efficacy in placebo-controlled single case studies

1994

Systematic variation of treatment (alternating active drug and placebo in four treatment periods) in individual patients is proposed to collect preliminary evidence for a therapeutic effect of sulpiride in chronic depression; the ARIMA model is applied to evaluate the intervention effects of the tentatively effective treatment in single subjects. Ten single cases of chronic depression with a diagnosis of major depression or dysthymia were selected and seven of these provided evidence for beneficial effects of sulpiride with regard to treating the symptoms of depression and anxiety. However, the drug effects were intraindividually not always replicable. The results obtained with these single…

Antibiotic treatment of Crohn's disease: results of a multicentre, double blind, randomized, placebo-controlled trial with rifaximin.

2006

1. Aliment Pharmacol Ther. 2006 Apr 15;23(8):1117-25. Antibiotic treatment of Crohn's disease: results of a multicentre, double blind, randomized, placebo-controlled trial with rifaximin. Prantera C, Lochs H, Campieri M, Scribano ML, Sturniolo GC, Castiglione F, Cottone M. Operative Unit of Gastroenterology, St Camillo-Forlanini Hospital, Rome, Italy. prantera@tin.it BACKGROUND: Clinicians often employ antibiotics in Crohn's disease. Rifaximin is active against bacteria frequently found in the intestinal mucosa of Crohn's disease patients. AIM: To evaluate the difference in efficacy between once and twice/daily oral administration of rifaximin and placebo in the treatment of active Crohn's …

Shock wave application for chronic plantar fasciitis in running athletes. A prospective, randomized, placebo-controlled trial.

2003

Background:Recent articles have reported success with repeated low-energy shock wave application for treatment of chronic plantar fasciitis in runners.Hypothesis:Shock wave treatment for chronic plantar fasciitis is safe and effective.Study Design:Prospective, randomized, placebo-controlled trial.Methods:Forty-five running athletes with intractable plantar heel pain for more than 12 months were enrolled; half were assigned to a treatment group that received three applications of 2100 impulses of low-energy shock waves, and half received sham treatment. Follow-up examinations were performed at 6 months and at 1 year by a blinded observer.Results:After 6 months, self-assessment of pain on fir…

Ciamexone in endocrine orbitopathy. A randomized double-blind, placebo-controlled study.

1990

Abstract The influence of ciamexone on the activity and course of endocrine orbitopathy was investigated. Fifty-one patients with active orbitopathy classes II-VI were allocated randomly to two groups: over a period of six months, 26 patients received 300 mg/day ciamexone and 25 patients received placebo tablets. In both groups, prednisolone was administered in addition in the first four weeks. Ophthalmological investigations and clinical tests as well as orbit sonography were carried out before as well as one, three and six months after the beginning of therapy. Before and after treatment, computer tomography of the orbit was performed. Symptoms and signs did not show any significant impro…

Double-blind, randomized, placebo-controlled trial of allergen-specific immunotherapy with the major allergen Alt a1

2019

Background: There have been few studies conducted on the efficacy and safety of specific immunotherapy with allergen extracts of fungi compared with other allergen extracts, and there are no data on the major allergen Alt a 1 of the fungus Alternaria alternata. Objectives: We sought to evaluate the efficacy and safety of subcutaneous immunotherapy with 2 different doses of Alt a 1 in patients with rhinoconjunctivitis caused by sensitization to A alternata. Method: We performed a multicenter, randomized, double-blind, placebo-controlled trial with Alt a 1 administered subcutaneously in patients with allergic rhinoconjunctivitis with or without controlled asthma aged 12 to 65 years. Three gro…

A multicenter, double-blind, randomized, placebo-controlled trial of the β3-adrenoceptor agonist solabegron for overactive bladder

2012

Abstract Background β-Adrenoceptor agonists are effective in animal models of bladder dysfunction, and the human bladder primarily expresses the β3 receptor subtype. Objective To evaluate the efficacy and tolerability of the highly selective and potent β3-adrenoceptor agonist solabegron in a clinical proof-of-concept study in incontinent women with overactive bladder (OAB). Design, setting, and participants This was a randomized, double-blind trial in adult women with OAB (one or more 24-h incontinence episodes and eight or more average 24-h micturitions). Interventions Solabegron 50mg ( n =88), solabegron 125mg ( n =85), or placebo ( n =85)—all twice daily—were administered. Outcome measur…

Effects of Nrf2 deficiency on bone microarchitecture in an experimental model of osteoporosis

2014

Objective. Redox imbalance contributes to bone fragility. We have evaluated the in vivo role of nuclear factor erythroid derived 2-related factor-2 (Nrf2), an important regulator of cellular responses to oxidative stress, in bone metabolism using a model of postmenopausal osteoporosis. Methods. Ovariectomy was performed in both wild-type and mice deficient in Nrf2 (Nrf2-/-). Bone microarchitecture was analyzed by CT. Serum markers of bone metabolism were also measured. Reactive oxygen species production was determined using dihydrorhodamine 123. Results. Sham-operated or ovariectomized Nrf2 -/- mice exhibit a loss in trabecular bone mineral density in femur, accompanied by a reduction in co…

Synthesis, characterization of diorganotin(IV) complexes of N-(2-hydroxyarylidene)aminoacetic acid and antitumour screening in vivo in ehrlich ascite…

2001

Some new diorganotin(IV) complexes have been prepared by reacting potassium N-(2-hydroxyarylidene)aminoacetate with R2SnCl2(R = Me,nBu,Ph). The complexes have been characterized by 1H,13C,119Sn NMR, IR and 119mSn Mössbauer spectroscopic techniques in combination with elemental analysis. In the solid state, the complexes possess penta- and hexa-coordinated tin centres. The hexa-coordinated tin complexes were found to dissociate in solution, giving rise to penta-coordinated species as revealed by 119Sn NMR spectroscopy. Antitumour screening in vivo of the complexes L4snPh2,L4SnPh2· Ph3SnCl and L4SntBU2·t Bu2SnCl2 (L4 = N-(2-hydroxyacetophenone)aminoacetate) is also reported. Copyright © 2001 …
