Clinical Trials

The microbiome within the gut lumen has been found in prior studies to differ in individuals with C. difficile infection (CDI) in comparison to those without diarrhea. The microbiome associated with the mucosal surface on the colon has been noted to differ from that of the lumen in other clinical scenarios, although this has not been studied in depth in patients with CDI. The goal of this research is to characterize the mucosal microbiome in patients with CDI after treatment to characterize this microbiome and determine the effect on recurrence of CDI.

The purpose of this study is to describe the results of antibiotic resistant organisms after the use of topical antibiotics in the treatment of chronic rhinosinusitis.

The purpose of this study is to determine the percentage of patients at moderate risk for infective endocarditis (IE) who are receiving antibiotic prophylaxis post-2007 in Olmsted County, Minnesota.

Women have problems with oral antibiotics, including vagina and bowel infections. Also, bacteria causing urinary infections are becoming more resistant to oral antibiotis. Placement of antibiotic directly into the bladder does not cause these problems and are at doses that are may be able to stop bacteria from being resistant to antibiotics.

The purpose of this study is to determine whether 2-drug therapy is non-inferior to 3-drug therapy against pulmonary mycobacterium avium complex (MAC) disease, and whether 2-drug therapy is better tolerated than 3-drug therapy.

The purposes of this study are to determine if patients treated with fluoroquinolone (FQ) antibiotics have depletion of mitochondrial DNA (mtDNA) in buccal swab samples, and whether the degree of depletion correlates with the likelihood of developing FQ-associated toxicity.

2nd arm - An additional group of patients will be enrolled if they previously received FQ antibiotics. appear to be symptomatic and have a previously collected muscle or nerve biopsy for clinical purposes available for this research study. 

The purpose of this study is to characterize mucosal and luminal microbiome in patients diagnosed with Clostridium difficile infection (CDI), at the time of diagnosis and after treatment, to determine the effect of mucosa associated microbiome on outcome of CDI and the effect of antibiotic treatment on mucosa associated microbiome

The study is investigating the ability of UroGen's MitoGel™ procedure to treat urothelial carcinoma tumors from the upper urinary tract. If this treatment will prove to be effective this will lead to the development of a new treatment approach for patients suffering from Low Grade Upper Urinary Urothelial Carcinoma (UTUC).

The purpose of this study is to observe and characterize the pharmacokinetics of anti-pseudomonal beta-lactam antibiotics (cefepime, piperacillin/tazobactam, meropenem) in critically ill adults..

The purpose of this study is to analyze the effectiveness of antibiotics and closer monitoring on decreasing infection in patients discharging with a chest tube and valve in place.

The purpose of this study is to determine if the use of preoperative  antibiotics given to prevent infection actually decreases the postoperative risk in patients having surgery to remove kidney stones.

The purpose of this study is to compare change in SNOT-22 score in patients who received medication therapy such as oral antibiotics, topical antibiotics, oral corticosteroids, topical corticosteroids, leukotriene receptor antagonist, and interleukin 5 receptor antagonist following endoscopic sinus surgery versus control in patient with chronic sinusitis with nasal polyps and a positive culture.

The purpose of this study is to assess the effectiveness and safety of D-PLEX administered concomitantly over a period of 90 days (3 months)with the standard of care (SOC) IV prophylactic antibiotic treatment vs. SOC in prevention of post-cardiac surgery sternal infections.

The primary aims of this study are to determine whether extended oral prophylactic antibiotics after primary total joint arthropasty (TJA) decreases the incidence of periprosthetic joint infection (PJI) in a high-risk patient population, and to determine whether extended oral prophylactic antibiotics after primary TJA decreases the incidence of surgical wound complications in a high-risk patient population.
