To compare clinical features, diagnosis and therapeutic effect between pulmonary histoplasmosis and progressive disseminated histoplasmosis.
 Methods: A retrospective analysis for 12 cases of hospitalized patients with histoplasmosis, who was admitted in Xiangya Hospital, Central South University during the time from February 2009 to October 2015, was carried out. Four cases of pulmonary histoplasmosis and 8 cases of progressive disseminated histoplasmosis were included. The differences of clinical features, imaging tests, means for diagnosis and prognosis were analyzed between the two types of histoplasmosis.
 Results: The clinical manifestations of pulmonary histoplasmosis were mild, such as dry cough. However, the main clinical symptoms of progressive disseminated histoplasmosis were severe, including recurrence of high fever, superficial lymph node enlargement over the whole body, hepatosplenomegaly, accompanied by cough, abdominal pain, joint pain, skin changes, etc.Laboratory examination showed pancytopenia, abnormal liver function and abnormal coagulation function. One pulmonary case received the operation of left lower lung lobectomy, 3 cases of pulmonary histoplasmosis and 6 cases of progressive disseminated histoplasmosis patients were given deoxycholate amphotericin B, itraconazole, voriconazole or fluconazole for antifungal therapy. One disseminated case discharged from the hospital without treatment after diagnosis of histoplasmosis, and 1 disseminated case combined with severe pneumonia and active tuberculosis died ultimately.
 Conclusion: As a rare fungal infection, histoplasmosis is easily to be misdiagnosed. The diagnostic criteria depends on etiology through bone marrow smear and tissues biopsy. Liposomeal amphotericin B, deoxycholate amphotericin B and itraconazole are recommended to treat infection for histoplasma capsulatum.

Korea is not known as an endemic area for Histoplasma. However, we experienced a case of histoplasmosis in a person who had never been abroad. A 65-year-old female was admitted to the hospital for evaluation of multiple lung nodules. A computed tomography (CT) scan of the chest showed multiple ill-defined consolidations and cavitations in all lobes of both lungs. The patient underwent a CT-guided lung biopsy, and a histopathology study showed findings compatible with histoplasmosis. Based on biopsy results and clinical findings, the patient was diagnosed with chronic cavitary pulmonary histoplasmosis. The patient recovered completely following itraconazole treatment. This is the first case report of pulmonary histoplasmosis unconnected with either HIV infection or endemicity in Korea.

OBJECTIVETo clarify the clinical feature, diagnosis and therapy of the pulmonary cryptococcosis (PC).

METHODSA retrospective study of cases with PC who were diagnosed by pathological examinations between January 1996 and December 2010 was conducted. Eighty-one cases were enrolled in the study (58 male and 23 female patients; mean age of (51±11) years). Forty-one cases were asymptomatic at the time of diagnosis. There were single pulmonary lesions in 50 cases, and multiple lesions in 31 cases. Fourteen lesions (17.3%) were located in left upper lobe, 27 (33.3%) in left lower lobe, 21 (25.9%) in right upper lobe, 3 (3.7%) in right middle lobe, 28 (34.6%) in right lower lobe, and 3 (3.7%) diffusely involved bilateral lungs. The tumors ranged from 0.8 to 10.0 cm in diameter with a mean of (2.9±1.8) cm. All the cases were misdiagnosis prior to the surgical resection, and histologically confirmed by postoperative pathological specimens.

RESULTSAll the cases received surgical treatment including complete resection in 69 cases, and palliative resection in 12 cases. Resections were performed by means of video-assisted thoracoscopy in 31 cases and thoracotomy in 50 cases. Surgical resections included pulmonary wedge excisions in 42 cases, and lobectomies in 39 cases. After histological confirmation, 63 cases (77.8%) were treated with antifungal agents, which consisted of fluconazole in 38 cases, itraconazole in 18 cases, amphotericin B in 6 cases, and flucytosine in 4 cases. There were no intraoperative death, but two cases died for cryptococcal meningoencephalitis in the postoperative period. Operative morbidity occurred in 7 (8.6%) cases. The median follow-up was 42.5 months (6 to 84 months). There were 2 local relapses of PC, and 9 cases with complications of anti-fungal agents.

CONCLUSIONSThe clinical manifestations of PC are mild and non-specific, with no characteristic radiographic manifestations. Surgical resection is usually indicated for definite diagnosis and treatment. Antifungal drug therapy is indispensable even after complete resection.

BACKGROUNDIn our clinical practice we have been attracted by a group of patients with airway aspergillosis who have airway obstruction; we termed the condition as pseudomembranous necrotizing tracheobronchial aspergillosis (PNTA). In this study we analyzed the clinical data from patients with PNTA, so as to guide the diagnosis and treatment of the disease.

METHODSA total of 16 PNTA patients were treated in Changhai Hospital from January 2000 to January 2009. Their clinical data, including the demographic information, clinical symptoms, imaging findings, bronchoscopy findings, treatment strategies and efficacy, and prognosis, were retrospectively analyzed.

RESULTSAll 16 patients were found to have primary systemic immunodeficiency diseases and/or damage of the focal airways. Nine patients (9/16, 56.3%) had pulmonary and tracheobronchial tumors, 5/16 (31.3%) had tracheobronchial involvement secondary to non-pulmonary tumors, and 2/16 (12.5%) had lung transplantation. The most common causes of PNTA included local radiotherapy (10/16, 62.5%), repeated chemotherapy (7/16, 43.8%) and recurrent intervention therapy by bronchoscope (4/16, 25.0%). Aspergillus fumigatus was the most frequent pathogen (62.5%, 10/16). The main clinical manifestations included progressive dyspnea (14/16, 87.5%) and irritable cough (12/16, 75.0%). The trachea was involved in 9/16 patients (56.3%), right main bronchus in 10/16 (62.5%). All 16 patients were treated with systemic anti-aspergillosis agents, local anti-aspergillosis agents with amphotericin B inhalation and direct perfusion of amphotericin B by bronchoscope, and interventional treatment by bronchoscope to ensure an unobstructed airway. The total efficiency was 31.3%.

CONCLUSIONSPNTA is an infectious disease caused by aspergillus and it mainly involves the trachea, primary bronchus and segmental bronchus. A. fumigatus is the most common pathogen. PNTA can pose a severe clinical threat and often occurs after systemic immunodeficiency and/or local airway damage, with the main symptoms including dyspnea and irritable cough. Bronchoscopic findings supply the main evidence for diagnosis of PNTA. Treatment of PNTA is difficult and requires a long course. Systemic and local anti-aspergillosis agents plus bronchoscopy debridement can improve the prognosis of the disease.

BACKGROUNDInvasive pulmonary mycosis is the most common type of invasive fungal infection. It is often severe and difficult to treat, and is accompanied by high mortality. In this study, we aimed to evaluate the efficacy and safety of intravenous itraconazole followed by oral itraconazole solution in the treatment of invasive pulmonary mycosis and to determine the distribution of different fungi species.

METHODSThis was a multi-center, open-label study which enrolled 71 patients who were diagnosed as invasive pulmonary mycosis between July 2007 and January 2009. All patients received intravenous itraconazole therapy followed by oral itraconazole solution with a total treatment duration of 6 weeks. Intravenous itraconazole was given at a dose of 200 mg bid (intravenous infusion every 12 hours) for the first two days, 200 mg qd for the subsequent 12 days. Sequential oral itraconazole solution was given at a dose of 100 mg bid for 4 weeks. Efficacy and safety were assessed according to clinical as well as microbiological criteria.

RESULTSSeventy one patients participated in this study. Of the 60 patients in the full analysis dataset, the clinical response rate was 61.7% and the mycological eradication rate was 66.7%. The overall response rate was 66.7%. Drug-related adverse events occurred in 18.0% of patients: hypokalemia, liver function impairment and mild gastrointestinal side effects were the most common. One patient suffered from severe adverse event, with limb and facial swelling.

CONCLUSIONThis study showed that in patients with invasive pulmonary mycosis, intravenous itraconazole followed by oral itraconazole solution therapy was safe and effective.

OBJECTIVETo summarize the clinical features of invasive pulmonary fungal infection (IPFI) secondary to malignant blood diseases (MBD).

METHODSWe retrospectively analyzed the clinical data of 52 patients with IPFI secondary to MBD admitted to Peking Union Medical College Hospital from January 1995 to December 2008.

RESULTSThe incidences of IPFI secondary to acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), non-Hodgkin's lymphoma (NHL), and aplastic anemia (AA) were 4.6%, 3.2%, 2.8%, and 2.5%, respectively. In patients with IPFI secondary to AML, 88.5% (23/26) of the patients suffered from the infections during the non-remission (NR) period (including relapse), and 11.5% (3/26) in the complete-remission (CR) period. In all the patients with IPFI secondary to malignant blood diseases, 86.5% (45/52) of MBD were neutropenic or agranulocytic, and 67.3% (35/52) had been treated with broad-spectrum antibiotics for more than 96 hours before anti-fungal therapy. The total mortality after anti-fungal therapy was 13.7% (7/51). More than half of patients with fluconazole or itraconazole as the first-line therapy had to switch to other medicines because of poor infection control.

CONCLUSIONSIPFI secondary to MBD is most common in AML patients. Patients with NR of AML, neutropenia or agranulocytosis, and long-term broad-spectrum antibiotics usage are susceptible to IPFI. Fluconazole and itraconazole have low efficacy, and other more potent anti-fungal medicines should be considered.
