Clinical analysis of invasive fungal infection in children of nephrology department / 中华实用儿科临床杂志

ABSTRACT

Objective To explore the clinical features of invasive fungal infection in 27 children treated at nephrology department between 1999 and 2014.Methods Twenty-seven cases of invasive fungal infection at nephrology department were analyzed retrospectively.Results Candida urinary infection was found in 9 cases,pneumocystis carinii pneumonia were found in 8 cases,invasive pulmonary aspergillosis and urinary aspergillosis found in 4 cases and 1 case respectively,cryptococcus neoformans meningitis and pulmonary candidiasis found respectively in 2 cases,and pulmonary filamentous fungal disease was found in 1 case.These 27 cases showed different features of illness10 primary nephrotic syndrome,7 secondary nephrotic syndrome,6 malformation of urinary development and 4 preterm birth ＜ 32 weeks gestational age with low birth weight.All of the cases had the history of taking antibiotics.Seventeen cases of them had used corticosteroid and cytotoxic drugs in a long-term.Sixteen cases had experienced invasive procedures.All children had fever in varying degrees,14 cases showed gasp,7 cases had progressive hypoxia and respiratory failure,and 5 cases developed into multiple organs failure.Chest computed tomographic (CT) imaging data showed diffuse ground-glass opacity with mosaic sign of pneumocystis carinii pneumonia(8 cases).The features of pulmonary aspergillosis included multiple nodules and cavity in bilateral lungs (4 cases).The radiologic findings showed patching lesions with indistinct edge and uncertained density of bilateral middle-lower lung fields with pulmonary candidiasis (2 cases).Full dose of antifungal drug was given to 23 cases of them,16 cases recovered completely,3 got better,4 cases died.Four cases gave up full dose antifungal therapy.Conclusions Long-term use of corticosteroid and cytotoxic drugs,use of broad-spectrum antibiotics,invasive therapies,such as indwelling centralvenous catheters,endotracheal intubation with mechanical ventilation,and preterm birth with low birth weight were risk factors in predicting invasive fungal infection.Chest CT findings were different among these cases.Even though not specific,the relatively differences were helpful to the differential diagnosis of these diseases.
