  • Clinicopathological Features of Acquired Immune Deficiency Syndrome Combined with Pneumocystis carinii Pneumonia

    ObjectiveTo summarize the clinical, radiological and pathological characteristics of acquired immune deficiency syndrome (AIDS) combined with Pneumocystis carinii pneumonia (PCP), so as to improve the clinicians' understanding of the disease. MethodsThe clinical data of 50 AIDS patients combined with PCP admitted between February 2006 and May 2015 were retrospectively analyzed, including medical history, physical signs, laboratory examination, chest high resolution CT (HRCT), pathological characteristics, treatment and prognosis, etc. ResultsThe clinical features of AIDS patients combined with PCP included cough, dyspnea and fever, without obvious positive signs in the lung.The patients were divided as a mild group, a moderate group and a severe group according to the levels of PaO2.There was significant difference among three groups in serum albumin level [(23±3) g/L vs. (30±5) g/L and (28±6) g/L, P < 0.01].There were no significant differences among three groups in CD4+ T lymphocyte and lactate dehydrogenase (LDH) (P > 0.05).The typical chest radiograph feature of HRCT was ground-glass shadows in both lungs, and may be associated with reticular shadows or "gravel sign" and cyst.Of 50 patients, 16 patients were diagnosed via pathology of transbronchial lung biopsy(TBLB) and only 5 patients were diagnosed via silver staining of the bronchoalveolar lavage fluid (BALF).The other patients were clinically diagnosed.100% of the patients were treated with sulfamethoxazole (SMZco), 64%with caspofungin, and 72% with glucocorticoid.All the patients relieved with no death in hospital. ConclusionWhen a patient got cough, dyspnea and fever, especially ground glass on HRCT in both lungs, AIDS combined with PCP should be highly considered, and diagnostic treatment with SMZco and CD4+ T lymphocyte measurement should be conducted as soon as possible, so as to reduce misdiagnosis and mortality.

  • 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.

  • Clinical,Radiological and Pathological Features of Hypersensitivity Pneumonitis: 24 Cases Analysis

    ObjectiveTo improve clinicians' knowledge of hypersensitivity pneumonitis (HP). MethodsWe retrospectively analyzed the clinical data of 24 HP patients who were diagnosed in the Affiliated Drum Tower Hospital of Nanjing University Medical School during February 2005 to February 2013. The clinical,radiological and pathological features of those patients were summarized. ResultsAmong those 24 patients,15 were male and 9 were female,with mean age of (48±13) years. All patients had a history of environmental exposure. Two patients showed acute clinical manifestations,and there were 17 subacute and 5 chronic cases. The main clinical manifestations were dyspnea,cough,sputum,fever and weight loss with hypoxemia via blood gas analysis. Restrictive ventilatory impairment was the most frequent functional pattern,and the carbon monoxide diffusing capacity was decreased. Pulmonary function test showed restrictive ventilatory defect and gas interchange disturbance. The features of chest HRCT included diffuse ground-glass attenuation and/or patchy consolidation,centrilobular micronodules,mosaic sign,reticular and/or honeycombing lesions. Bronchoalveolar lavage fluid (BALF) demonstrated an increase of total cell counts with predominant lymphocytosis. The transbronchoscopic lung biopsy (TBLB) pathological examination revealed lymphocytic alveolitis,noncaseating granuloma,and interstial pneumonia. All patients were treated by corticosteroid and avoided antigen exposure and showed significant clinical and radiological improvement. ConclusionThe diagnosis of HP is difficult. In most cases (acute and subacute HP),a diagnosis can be made by combination history of exposure,chest HRCT manifestations,cell classification of BALF and pathological examination of TBLB. For atypical cases (chronic HP),a surgery lung biopsy is needed for multi-disciplinary diagnosis including pathologist,radiologist and pulmonologists.
