Abstract:
Objective:To investigate the efficacy and safety of micafungin (MCF) for pulmonary invasive fungal disease (PIFD) in pediatric patients with acute leukemia or post hematopoietic stem cells transplantation.
Method:Twenty-five neutropenic PIFD children with acute leukemia or post hematopoietic stem cells transplantation in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were selected from January 2012 to June 2015, including 12 males and 13 females, age range 2-15 (average 6.2±2.0) years. There were 12 cases of acute leukemia (AL) after chemotherapy, 4 cases of acute leukemia (AL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and 9 cases of β-thalassemia major after allo-HSCT. All children received MCM for the treatment of PIFD, the dosage of MCM was 3-4 mg/ (kg·d) , once a day. The children received 2 to 6 courses of treatment, individually with a course of 7 days. 1, 3-β-D glucan assay (G test), galactomannan antigen test (GM test), high-resolution CT and the biochemical indexes for organ functions were closely monitored.
Result:Twenty-five cases were diagnosed as PIFD, including 2 patients diagnosed as proven, 6 as probable and 17 as possible. Of the 25 cases, 1 was confirmed aspergillus by biopsy pathology and 1 was candida albicans by blood culture. The G and GM test with positive results was 5 and 2 respectively. Chest CT scans of the 25 cases had obvious lesions: air crescent sign and cavitation in 4 cases, diffuse ground glass change in 9 cases, double lung scattered patchy, small nodules and cord like high density shadow in 7 cases, unilateral or bilateral chest wall wedge-shaped consolidation edge in 5 cases and pleural effusion in 5 patients. The effective rate of MCF in treatment of PIFD was 68% (17/25), including 13 cases cured, 4 cases improved, 4 cases were improved clinically and in 4 cases the treatment was ineffective. Eight cases were effective in MCF monotherapy group (12 cases) and nine were effective in MCF combined therapy group(13 cases), respectively. Side-effects including allergies, gastrointestinal side effects, electrolyte disturbances, impairment of liver and kidney function, and myelosuppression were not found in those children treated with MCF.
Conclusion:Micafungin is effective and safe in the treatment of pulmonary invasive fungal disease in pediatric patients with acute leukemia or post hematopoietic stem cell transplantation.
