Background: Antibiotic treatment of Clostridium difficile infection (CDI) has a high failure rate. Fecal microbiota transplantation (FMT) has proven very effective in treating these recurrences. 

Objectives: To determine which method of fecal microbiota transplantation (upper or lower gastrointestinal) and which type of donor (a relative or unrelated) is superior.

Methods: This is a retrospective analysis of treatment protocols and outcomes in 22 patients with refractory or recurrent CDI who underwent FMT at two Israeli facilities. Each center used a different donor type, stool preparation and method of delivery. The Tel Aviv Sourasky Medical Center used unrelated fecal donors and frozen stool samples and delivered them primarily (92%) via the lower gastrointestinal (GI) tract. Shaare Zedek Medical Center used fresh donor stool of relatives and delivered them primarily (90%) via the upper GI tract.

Results: FMT had an overall 2 month cure rate of 89%. Patients treated with FMT that was executed through the lower GI tract recovered faster from the infection (1.6 ± 1.08 vs. 2.4 ± 1 days for the upper tract, P = 0.03). The results also showed that patients who received lower GI tract FMTs were more likely to be cured of CDI (100% vs. 75% for upper tract FMTs, P = 0.16). Five patients (22%) died of CDI/FMT-unrelated causes and two (10%) died of CDI/FMT-related causes during the study period.

Conclusions: Lower GI tract FMT is a safe and effective treatment for refractory and recurrent CDI, and yields quicker results than upper GI tract FMT. 

 

Background: Cardiac rupture is a rare but ominous complication of myocardial infarction.

Objectives: To study the clinical presentation, medical course, outcome and echocardiographic predictors of patients with myocardial rupture.

Methods: We evaluated 15 consecutive patients with cardiac rupture during a 4 year period in our department. The current report explores the presence of potential risk factors, timing, relation to the thrombolysis, coronary interventions and outcome.

Results: The index event in all patients was first ST elevation myocardial infarction. In seven patients rupture occurred in the first 24 hours. Pericardial effusion on admission with a clot was present in three patients. Five patients received thrombolytic therapy. Only three patients underwent coronary angioplasty, but in one case it was performed late and in two patients the culprit artery could not be opened. Six patients reached the operating room, of whom three survived.

Conclusions: The lack of early mechanical reperfusion in acute myocardial infarction and thrombolytic therapy are risk factors for cardiac rupture. Pericardial effusion on admission and evidence of a clot are echocardiographic indicators of cardiac rupture and should alert the medical team to further assess the possibility of cardiac rupture.
