Active clinical trials for "Infections"

Previous studies suggest that chronic idiopathic thrombocytopenic purpura is associated with Helicobacter pylori infection. The objective is to study the effect of Helicobacter pylori eradication on platelet count.

Tigecycline's activity against resistant organisms, as well as significant coverage of both gram-positive and gram-negative bacteria, may provide a valuable therapeutic alternative in treating patients with complicated skin and/or skin structure infections.

Researchers want to find out if a drug called Cipro® XR (ciprofloxacin extended-release) can help people with a complicated urinary tract infection caused by a kind of bacteria called Pseudomonas aeruginosa. The study doctor will give Cipro XR to some people to see if it is safe and works to treat complicated urinary tract infections caused by Pseudomonas aeruginosa. The study doctor will also gather information about using Cipro XR to treat complicated urinary tract infections caused by other bacteria. About 500 people with complicated urinary tract infections who are 18 years old and older will join this study. Cipro XR is approved by the U.S. Food and Drug Administration (FDA) for the treatment of complicated urinary tract infections and acute uncomplicated pyelonephritis (inflammation of the kidney). The dose of Cipro XR used in this study (1000 mg a day for 7 to 14 days), has been shown to be safe and effective. This study is being done to gather more information on using this dose of Cipro XR for complicated urinary tract infections caused by Pseudomonas aeruginosa, as well as by other bacteria.

To assess if a sequential treatment regimen better eradicates H. pylori than does a triple drug regimen in adults with dyspepsia or peptic ulcer disease.

The purpose of this study is to compare the antiviral activity of two treatment groups for HIV chronic infection: a QD regimen of didanosine, lamivudine and efavirenz versus a BID regimen of zidovudine, lamivudine and efavirenz. Both will be administered with food in the starting treatment of human immunodeficiency virus infection at Week 48.

The purpose of this study is to evaluate the safety and effectiveness of levofloxacin, an antibiotic, compared with another antibiotic, ciprofloxacin, in the treatment of adults with uncomplicated infections of the skin and the supportive layers beneath the skin.

The purpose of the study is to compare the safety and effectiveness of oral levofloxacin (an antibiotic) with that of oral ciprofloxacin in the treatment of complicated urinary tract infections in adults.

The purpose of this study is to evaluate any differences in the effectiveness, safety, and tolerability of PREZISTA (darunavir; DRV) 600 mg, administered with ritonavir (RTV) 100 mg twice a day on virologic response (defined as a viral load (VL) of < 50 copies/mL) over a 48-week treatment period in HIV-positive women and men. Additional antiretroviral (ARV) agents will also be administered and will be chosen by the Investigator based on resistance testing and prior treatment history (referred to as the Optimized Background Regimen (OBR)).

This is a 24-week study to evaluate the efficacy and safety of a once-daily ritonavir-boosted fosamprenavir regimen (1400mg/100mg QD) to a 200mg ritonavir-boosted fosamprenavir regimen administered either twice-daily or once-daily.

This 3 arm study will compare the efficacy and safety of beta-lactam with that of 'standard care' in patients with complicated skin and skin structure infections requiring hospitalization. Patients will be randomized to receive 1)beta-lactam 750mg iv q8h 2)beta-lactam 1500mg iv q8h or 3)'standard care' [PRP (nafcillin or flucloxacillin) or vancomycin, plus aztreonam or ciprofloxacin]. The anticipated time on study treatment is <3 months and the target sample size is 100-500 individuals.
