Therefore, an assessment of safety and efficacy is needed in order to generalize this practice. The publication of this study can potentially introduce a new alternative to guideline-directed therapies for secondary prevention of SBP. Doxycycline is non-inferior to guideline-directed therapies regarding safety and efficacy in primary and secondary prophylaxis for SBP.', 'detailedDescription': 'Spontaneous bacterial peritonitis (SBP) is a common and serious complication in cirrhotic patients with a reported mortality rate of 20 to 30%.1-3 A SBP diagnosis requires abdominal paracentesis and is made in the presence of an elevated ascitic fluid absolute polymorphonuclear leukocyte (PMN) count without an evident intra-abdominal, surgically treatable source of infection.2,3 Common pathogens associated with SBP are Gram-negative colonic organisms. However, in recent years, Gram-positive pathogens have become more common, suggesting the need to evaluate SBP management.1,4-6 The recurrence rate of SBP after an initial episode has been reported to be as high as 70%.1-3 Currently, the American Association for the Study of Liver Disease (AASLD) and European Association for the Study of the Liver (EASL) guidelines recommend the use of sulfamethoxazole/trimethoprim, norfloxacin, or ciprofloxacin for the prevention of recurrent SBP. Fluoroquinolones as a class have had increased black box warnings in recent years, making ciprofloxacin fall out of favor for long-term prophylaxis.5 Sulfamethoxazole/trimethoprim is extensively metabolized by the liver and is contraindicated in marked liver impairment.8 Therefore, it is necessary to search for a prophylaxis alternative with similar efficacy and a better safety profile.\n\nDoxycycline is a broad-spectrum antibiotic that covers Gram-positive bacteria, including Streptococcus spp., resistant strains of Staphylococcus and Enterococcus, and Gram-negative bacteria, including Enterobacteriaceae. One randomized trial in cirrhotic patients with a previous episode of SBP showed that doxycycline was associated with a reduction in inflammatory markers, such as interleukin-6 and C-reactive protein, suggesting potential benefits of doxycycline in this patient population.7 At Methodist Dallas Medical Center (MDMC) and the Liver Institute at MDMC, doxycycline has been utilized for both primary and secondary prevention of SBP. In order to compare doxycycline with guideline-directed therapies for SBP prevention in cirrhotic patients, a retrospective, cohort study was designed to review patients who meet the criteria from July 2014 to July 2018. This study aims to compare the efficacy of doxycycline with that of guideline recommended therapies for primary and secondary SBP prophylaxis, the safety of doxycycline with that of guideline recommended therapies for primary and secondary SBP prophylaxis, and identify the association between chemoprophylaxis and the risk of infections from multidrug resistant organisms (MDROs) in SBP.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients hospitalized at MDMC at the Liver Institute Clinic with a diagnosis of SBP based on ascitic fluid PMN count greater than 250 cells/mm3 from July 2014 to July 2018.', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Patients ≥ 18 year-old with refractory ascites who are candidates for SBP prophylaxis per clinician's decision\n* Patients diagnosed with cirrhosis based on clinical criteria\n* Patients with a diagnosis of SBP confirmed by paracentesis\n\nExclusion Criteria:\n\n* Patients who have secondary peritonitis other than SBP\n* Patients who have a history of liver transplant prior to the initial episode of SBP\n* Patients with incomplete medical records"}, 'identificationModule': {'nctId': 'NCT04153604', 'briefTitle': 'Doxycycline for the Prevention of Spontaneous Bacterial Peritonitis', 'organization': {'class': 'OTHER', 'fullName': 'Methodist Health System'}, 'officialTitle': 'Doxycycline for the Prevention of Spontaneous Bacterial Peritonitis', 'orgStudyIdInfo': {'id': '061.PHA.2019.D'}}, 'armsInterventionsModule': {'interventions': [{'name': 'doxycycline', 'type': 'DRUG', 'description': 'a tetracycline antibiotic that fights bacteria in the body.'}]}, 'contactsLocationsModule': {'locations': [{'zip': '75203', 'city': 'Dallas', 'state': 'Texas', 'country': 'United States', 'facility': 'Methodist Dallas Medical Center', 'geoPoint': {'lat': 32.78306, 'lon': -96.80667}}], 'overallOfficials': [{'name': 'Jessica Rago, PharmD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'The Methodist Hospital Research Institute'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Methodist Health System', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
