ObjectiveTo highlight the characteristics of pulmonary MALT lymphoma with diffuse lung disease. MethodsThe clinical,radiological and pathological data of two patients with pulmonary MALT lymphoma were analyzed,and relevant literature was reviewed. ResultsOne patient was a 59-year-old male with cough for five years while antibiotic treatment was ineffective. The chest CT scan demonstrated diffuse lung disease,bilateral multiple consolidation and ground-glass opacities,small nodules and bronchiectasis. Thoracoscopy biopsy was performed and the pathology study confirmed the diagnosis of MALT lymphoma. Another case was a 50-year-old female,who suffered from fever,cough and dyspnea. The chest CT scan revealed bilateral multiple patchy consolidation,with air bronchogram. The eosinophils count in blood was high. Diagnosed initially as eosinophilic pneumonia,she was treated with corticosteroids. The clinical symptoms were improved,but the CT scan revealed no change. After the computed tomography guided percutaneous lung biopsy,pathological examination confirmed the diagnosis of MALT lymphoma. ConclusionMALT lymphoma with diffuse lung disease is rare and easy to be misdiagnosed. The positive rate of bronchoscopy is low and percutaneous lung biopsy or thoracoscopy biopsy is more useful for diagnosis.
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.
