RESUMEN
Objectives: Pleural effusion (PE) is the most frequent pulmonary complication of dasatinib, a tyrosine kinase inhibitor (TKI). Concurrent pericardial effusions have been reported in about one-third of the cases. In this study, we aimed to investigate ascites generation in chronic-phase chronic myeloid leukemia (CML-CP) patients developing PE under dasatinib. Methods: We conducted a cross-sectional study to evaluate whether pericardial effusion and ascites accompany PE in CML-CP patients treated with dasatinib. For this purpose, consecutive patients with CML-CP who developed PE under dasatinib therapy have been evaluated with chest X-ray, transthoracic echocardiography, and abdominal ultrasonography. Results: There were seven patients, and the median age was 50 years (range, 31-73 years). Most of patients were male (n=5). All patients received imatinib as first-line TKI. Six patients received dasatinib following imatinib failure in second line. The median duration from dasatinib initiation to PE generation was 58 months (range, 8-135 months). Consequently, four patients had grade 1 pericardial effusion, and no patient had ascites. Conclusions: In our small study, dasatinib-related PE was associated with low-grade pericardial effusion but no ascites. There are hypothetical explanations of this phenomenon including the simultaneous activation/inhibition of kinases; however, more research needs to be performed on this topic.
RESUMEN
BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases with uncertain etiology. We aimed to determine the amounts of Akkermansia muciniphila and Faecalibacterium prausnitzii in the intestinal microbiota of these patients and to correlate their amounts with blood IL-8, IL-10, and IL-12 cytokine levels. METHODS: Thirty UC, 30 CDs, and 46 healthy controls were included. IL-8, IL-10, and IL-12 levels of blood samples were analyzed by ELISA. The amounts of Akkermansia muciniphila and Faecalibacterium prausnitzii were determined by the LightCycler 480 qPCR system. RESULTS: F. prausnitzii, A. muciniphila, IL-10, and IL-12 decreased in patient groups, while IL-8 decreased in UC but increased in CD. A significant difference was detected between the patient and control groups in terms of F. prausnitzii, A. muciniphila, and IL-8, but not for others. The amount of F. prausnitzii was correlated with IL-8 and IL-10 in UC and with IL-10 in CD patients. CONCLUSIONS: The decrease in the amount of F. prausnitzii was associated with the increase in UC disease severity. A. muciniphila and F. prausnitzii were detected in lower amounts in both diseases. F. prausnitzii decreased more with the severity of UC, suggesting that these bacteria may have complex roles in their etiopathogenesis.
