  • Secondary Pulmonary Alveolar Proteinosis Associated with Hematological Malignancy: Three Cases Report and Literature Review

    ObjectiveTo highlight the characteristics of secondary pulmonary alveolar proteinosis (PAP) associated with malignant hematological diseases. MethodsThe clinical data of three patients with secondary PAP were analyzed and the related literature was reviewed. ResultsThree patients were diagnosed with secondary PAP by exclusion of primary or autoimmune PAP and denied the history of inhalation of occupational dusts. Two patients with secondary PAP were associated with chronic myelocytic leukemia, and the third one was associated with myelodysplastic syndrome. The performance on HRCT of the PAP associated with hematological malignancy was different from the primary PAP. Three patients were pathologically diagonised by brochoalveolar lavage fluid. One patient was successfully treated with inhalation of granulocyte-macrophage colony-stimulating factor (GM-CSF). ConclusionsSecondary PAP associated with hematological malignancy is very rare. The untypical HRCT is the main cause of misdiagnosis. Some patients may benefit from GM-CSF theatment.

  • Risk Factors of Invasive Pulmonary Aspergillosis in Patients with Interstitial Pneumonia

    Objective To analyze the risk factors of invasive pulmonary aspergillosis (IPA) in patients with interstitial pneumonia. Methods The clinical data of 770 cases of interstitial pneumonia admitted between December 2010 and August 2015 were collected. Among them, 46 cases were combined with IPA and 724 cases were not ombined with IPA. The clinical data was analyzed to explore the risk factors of IPA in patients with interstitial pneumonia. Results Univariate analysis showed that in the aspects of age (t=3.348, P=0.001), serum albumin level (t=8.381, P < 001), broad-spectrum antibiotic used within 3 months (χ2=87.157, P < 001), long-term administration of glucocorticoid (χ2=57.462, P < 001), long-term administration of immunosuppressive agents (χ2=31.715, P < 001), imaging in UIP type (χ2=20.632, P < 001), diabetes mellitus (χ2=9.737, P=0.002) and heart failure (χ2=9.300, P=0.002), there were significant differences between two groups. After multivariate logistic regression analysis, broad-spectrum antibiotic used within 3 months (OR=4.773, P < 001), long-term administration of glucocorticoid (OR=9.195, P < 001), long-term administration of immunosuppressive agents (OR=2.662, P=0.046), imaging in UIP type (OR=5.725, P < 001), and diabetes mellitus (OR=3.847, P=0.003) were found to be the risk factors of IPA in patients with interstitial pneumonia. Serum albumin level was negatively correlated with the occurrence of IPA in patients with interstitial pneumonia. Conclusions Various factors contribute to the occurrence of IPA in patients with interstitial pneumonia. Miscellaneous appropriate measures should be taken to reduce the incidence of IPA.
