Three patients treated for intracranial malignant astrocytomas developed adult respiratory distress syndrome (ARDS). All three patients had a Karnofaky performance status score of at least 80% and similar clinical characteristics. All demonstrated hypersensitivity to phenytoin. ARDS occurred in two patients during radiotherapy and in one with radiation-induced brain damage following initial radiochemotherapy. ARDS occurred shortly after tapering the long-term administration of betamethasone. The initial symptoms were dry cough, fever, and generalized toxic eruption. Serum lactic acid dehydrogenase (LDH) concentrations were increased up to 2500 IU/l. Several days later, the patients suddenly complained of dyspnea. All patients fulfilled the diagnostic criteria for ARDS. Two patients recovered, but a young woman died. Clinical symptoms such as fever of unknown origin, dry cough and skin eruptions, accompanied by abnormally increased serum LDH concentrations during or following the tapering of long-term administration of corticosteroids, are warning signs of ARDS in patients being treated for malignant gliomas.

The aim of this study was to evaluate when the serum level of KL-6, a sensitive marker for idiopathic pulmonary fibrosis (IPF), rise prior to clinical onset of IPF. Eight hepatitis C virus (HCV)-positive patients with IPF were enrolled in this trial. The serum samples of these eight patients were stored -80 degrees C every 1-3 month during a follow-up period and enzyme-linked immunosorbent assay (ELISA) for KL-6 was done at the same time. Diagnosis of IPF was based on computed tomography and/or histology. Diagnosis of clinical onset of IPF was based on presence of dyspnea, dry cough, and audible fine crackles. At 1 year before clinical onset of IPF, the sensitivities of serum marker for IPF were 75% (6/8) for KL-6, 25% (2/8) for each of lactic acid dehydrogenase (LDH) and C-reactive protein (CRP). At 2 years before clinical onset of IPF, the sensitivities of the same serum markers were 62.5% (5/8), 12.5% (1/8) and 0% (0/8), respectively. The sensitivity of KL-6 at 1 and 2 year before clinical onset of IPF was significantly higher compared with LDH and CRP. Our results indicate that many future patients with IPF may have high levels of serum KL-6 at 1 or 2 years before clinical onset of IPF, suggesting that changes in serum KL-6 level can provide useful information for the early diagnosis of IPF in patients with HCV.

Histoplasmosis occurs in approximately 5% of acquired immunodeficiency syndrome (AIDS) patients in endemic areas and often evolves to a disseminated picture if diagnosis is delayed and/or CD4 count falls below 150 cells x mm(3) without high active antiretroviral therapy (HAART). This report presents clinical features of patients with histoplasmosis admitted from 1992 to 2005. Of the 57 individuals, 45 (79%) were male, aged 20-40 years; 30 (52.6%) presented histoplasmosis together with HIV diagnosis and 35 (61.4%) referred illness course up to 4 weeks. Fever, hepatomegaly and/or splenomegaly, dyspnea and skin lesions were noticed in 50 (87.7%), 38 (66.7%), 30 (52.6%) and 25 (43.9%) patients respectively. High levels of lactic acid dehydrogenase, X-ray lung interstitial pattern, pancytopenia and CD4 count <100 cells x mm(3) were observed in 48 (84.2%), 35 (66%), 34 (59.6%) and 33 (94%) patients respectively. Mycological diagnosis was performed by one or more methods in all patients. Thirty nine (68.4%) received amphotericin B and/or itraconazole. A cure rate was observed in 76.9% and nine (23.1%) died early during therapy. Otherwise death occurred in 18 (31.6%) before diagnosis was completed. Despite free HAART disposal in public Brazilian health services, histoplasmosis still occurs as the first AIDS baseline condition in patients without antiretroviral therapy, many of whom are not receiving any medical care for HIV infection.
