| NCT00163982 ↗ | Vasoactive Peptides in Portal Pressure | Unknown status | Bayside Health | N/A | 1969-12-31 | This study is looking at the detection of vasoactive peptides in portal hypertension. |
| NCT00359853 ↗ | Norfloxacin In The Primary Prophylaxis Of Spontaneous Bacterial Peritonitis | Completed | Hospital Clinic of Barcelona | Phase 4 | 2000-09-01 | Advanced liver disease and low ascitic fluid protein concentration have been identified as risk factors for spontaneous bacterial peritonitis in cirrhosis. Moreover, renal impairment and hyponatremia increase mortality rate of this infection. Aims: To investigate if oral administration of norfloxacin prevents the first episode of SBP, hepatorenal syndrome and improves survival in cirrhotic patients with ascites and low protein concentration in ascitic fluid (<15 g/L) and at least one of the following inclusion criteria: functional renal failure (serum creatinine ≥ 1,2 mg/dl or BUN ≥ 25 mg/dl), hyponatremia (serum sodium ≤ 130 mEq/L) or advanced liver disease (Child ≥ 9 points with serum bilirubin ≥ 3 mg/dl). Methods: Prospective, multicenter, randomized, double-blind placebo controlled trial comparing oral norfloxacin (400 mg/d; n=35) with placebo (n=35). |
| NCT00362752 ↗ | A Pilot Study of Norfloxacin for Hepatopulmonary Syndrome | Completed | University of Toronto | Phase 2 | 2006-10-01 | The hepatopulmonary syndrome (HPS)and pre-HPS is a disease seen in patients with chronic liver disease, whereby patients develop dilations in the blood vessels of the lungs, resulting in low oxygen levels and shortness of breath. In this study, each HPS and pre-HPS subject will be treated with a commonly used antibiotic called "norfloxacin" (approved for use in the treatment of gonorrhea, prostatitis and urinary tract infections) for a 4-week period. In order to ensure that any observed improvement was indeed due to norfloxacin, each subject will also be treated with a separate 4-week course of an identical placebo. There will also be a 4 week wash-out period (no study medication/placebo) between the 2 courses of treatment. The primary aim of the study will be to measure improvements in oxygen levels while on norfloxacin, although a number of secondary parameters will also be followed. |

| NCT00501995 ↗ | High Dose Cyclophosphamide for Treatment of Scleroderma | Completed | Johns Hopkins University | Phase 3 | 2001-02-01 | Systemic Sclerosis (Scleroderma) varies greatly in clinical manifestations, mode of presentation, and course. The natural history of this chronic autoimmune disease ranges from benign to fatal. Patients are classified into limited and diffuse scleroderma defined by the degree of skin involvement. Patients with limited disease (e.g. the C.R.E.S.T. syndrome) generally have mild disease and normal survival. However, patients with diffuse cutaneous scleroderma often have severe multi-system disease that is not only devastating emotionally and physically but is associated with a 60-70% five year survival and a 40-50% 10 year survival. No therapies have proven effective in the treatment of scleroderma. Strategy to treat scleroderma have included attempts to prevent fibrosis with drugs that interfere with collagen metabolism, attempts to modify the disease process by immunosuppression and attempts to alter the disease by vasoactive drugs. High dose of corticosteroids and other immunosuppressive drugs (e.g. chlorambucil, 5-fluorouracil, methotrexate, cyclophosphamide, cyclosporine) used at conventional doses have not proven curative, but have shown some benefit for inflammatory features of the disease (e.g. arthritis, myositis, fibrosing alveolitis). Both allogeneic and autologous bone marrow transplantation (BMT) have shown to modify and in some instances reverse a variety of animal models of autoimmune disease. This has prompted many investigators to propose the use of peripheral blood stem cell transplantation (PBSCT) for the treatment of autoimmune disease including scleroderma. Unfortunately, this approach risks infusing untreated autoreactive lymphocyte clones after the immunoablative preparative regimen. We have previously demonstrated that high-dose cyclophosphamide without BMT can induce durable and complete remissions in another autoimmune disease, severe aplastic anemia. Recent data with high dose cyclophosphamide show that it can induce complete remissions in other autoimmune hematologic disorders. The objective of this study is to determine whether high dose cyclophosphamide can induce a durable remission in scleroderma patients with life-threatening disease, and to determine toxicity of high dose cyclophosphamide in high risk scleroderma patients. |
| NCT00678613 ↗ | Role of Probiotics in the Prevention of Spontaneous Bacterial Peritonitis in Cirrhotic Patients: A Randomized Placebo Control Trial | Unknown status | All India Institute of Medical Sciences, New Delhi | Phase 2/Phase 3 | 2007-07-01 | Cirrhotic patients are predisposed to bacterial infection. A large proportion of which is spontaneous bacterial peritonitis(SBP), which are mainly caused by enteric bacteria.SBP in a cirrhotic patients is associated with a high mortality rate in the order of 30-80% per year.It has been demonstrated that cirrhotics who have an ascitic fluid protein concentration less than 1gm% are most susceptible to develop SBP by virtue of having low opsonising activity of ascitic fluid.Patients with liver cirrhosis have significant degrees of imbalance of intestinal flora.Translocation of intestinal bacteria being the major mechanism for the production of SBP. Long-term antibiotic (norfloxacin) is very effective in preventing SBP caused by gram negative bacteria.But the problem with the long-term antibiotic prophylaxis is the potential for the development of infection with antibiotic-resistant bacteria.Further, quinolones have no effect on gram positive bacteria which is becoming one of the important cause of SBP. Such experiences necessitate the need for strategies, other than antibiotic, to prevent intestinal bacterial overgrowth, bacterial translocation and SBP in patients with cirrhosis.Probiotics have been used successfully to alter the gut flora in many clinical conditions where growth and localization of non pathogenic bacteria replaces the pathogenic bacteria in the intestine.The probiotic bacteria, among which the most common are the lactose fermenting Lactobacilli, inhibit the growth of pathogenic bacteria by acidifying the gut lumen, competing for nutrients, and by producing antimicrobial substances. They adhere to the gut mucosa and by that are thought to prevent bacterial translocation from the gut. The purpose of this study is to determine the effectiveness of probiotics in the prevention of spontaneous bacterial peritonitis in patients with cirrhosis with low protein ascites and those already have developed an episode SBP. |
