Brief summary
Neutropenia after induction or consolidation therapy for acute myeloid leukemia (AML) patients is associated with a high morbi-mortality rates, especially due to infectious complications. These are managed according to international recommandations (ECIL and IDSA) with antibiotherapy and antifungal strategy. Although the patients suffer of digestive symptoms, intestinale complications are really less explored. Neutropenic enterocolitis (NE), cytomegalovirus (CMV) colitis, Clostridium difficile colitis, specific lesion, ischemic colitis are not well-known. No prospective study evaluate NE and these digestive complications which have high morbi-mortality rates.
Detailed description
This is the first prospective study on digestive affections in an homogeneous cohort of hematological patients. These affections are unknown in neutropenic patients with digestive symptoms after induction or consolidation courses pour AML although causing high morbi-mortality rates (infections, denutrition, loss of autonomy…). The aim of the study is to evaluate incidence of NE by clinical signs and with a systematic CT scan performed at day 5 of fever during aplastic period. An early diagnostic could decrease complications and evaluate gravity criteria which could imply surgery therapy. The physician will performe a CTscan with injection during the induction and/or every consolidation, at the same time as the thoracic CTscan (to research an invasive fungal bronchopulmonary infection), in front of a febrile neutropenia with persistent fever after 5 days of antibiotics and presence of digestive signs. The clinical, microbiological, radiological symptoms will be registered at every time of febrile neutropenia with digestive symptoms at induction and each consolidation courses. The patient will be get out of the study when the AML is refractory, hematopoietic stem cell transplantation is required or if whenever he want. The last visit will be at the end of consolidation courses.
Interventions
OTHERprospective study on digestive affections in an homogeneous cohort of hematological patients
Systematic realization during the induction and/or every consolidation of a CTscan with injection, at the same time as the thoracic CTscan (to research an invasive fungal bronchopulmonary infection), in front of a febrile neutropenia with persistent fever after 5 days of antibiotics and presence of digestive signs. Statement of the information characterizing the digestive affection: clinical symptoms, microbiological, characteristic, realized additional explorations, infectious complications and specific therapeutics. The abdominal scanner will be repeated in case of suspicion of complication or clinical worsening. In case of EC, the abdominal scanner will be realized before beginning the next cycle of AML treatment to evaluate digestive remission. Finally, a CT scan, will be performed when digestive disease, digestive neoplasia or digestive symptoms are noted at AML diagnosis.
