Invasive pulmonary aspergillosis resulting in respiratory failure during neutrophil recovery from postchemotherapy neutropenia in three patients with acute leukaemia

Abstract.,Takuma T, Okada K, Uchida Y, Yamagata A, Sawae Y (Kyushu University Graduate School of Sciences, Fukuoka, Japan; University of California, CA, USA; and Shin-kokura Hospital, Fukuoka, Japan). Invasive pulmonary aspergillosis resulting in respiratory failure during neutrophil recovery from postchemotherapy neutropenia in three patients with acute leukaemia (Case Report). J Intern Med 2002; 252: 173,177. Respiratory failure is a severe complication of invasive pulmonary aspergillosis (IPA). Its pathogenesis is not well understood. We herein describe three cases of subacute respiratory failure that occurred during the recovery phase of neutropenia following induction chemotherapy for acute leukaemia with IPA. In each case, severe neutropenia (19,85 days), high-grade fever, severe anaemia, the use of granulocyte-colony-stimulating factor and increasing infusion volume were noted. As the neutrophil count was recovering, the shadows on the chest X-ray expanded with progressing hypoxia. We should pay attention to the respiratory failure during the recovery phase of neutropenia in patients with IPA. [source]

Invasive pulmonary aspergillosis in chronic obstructive pulmonary disease: an emerging fungal pathogen

CLINICAL MICROBIOLOGY AND INFECTION, Issue 6 2005
F. Ader
Abstract Acute invasive pulmonary aspergillosis occurs predominantly in immunocompromised hosts, with increasing numbers of cases of invasive aspergillosis among patients with chronic obstructive pulmonary disease (COPD) being reported. Among 13 cases of invasive aspergillosis diagnosed in COPD patients admitted to the intensive care unit with acute respiratory distress, the only risk factor for invasive fungal infection was corticosteroid treatment. Invasive aspergillosis should be suspected in COPD patients receiving steroid treatment who have extensive pulmonary infiltrates. Survival depends on rapid diagnosis and early appropriate treatment. A decrease or interruption of steroid treatment should be considered as part of the overall therapeutic strategy. [source]

Aspergillus Colonization of the Lung Allograft Is a Risk Factor for Bronchiolitis Obliterans Syndrome

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 8 2009
S. S. Weigt
Multiple infections have been linked with the development of bronchiolitis obliterans syndrome (BOS) post-lung transplantation. Lung allograft airway colonization by Aspergillus species is common among lung transplant recipients. We hypothesized that Aspergillus colonization may promote the development of BOS and may decrease survival post-lung transplantation. We reviewed all lung transplant recipients transplanted in our center between January 2000 and June 2006. Bronchoscopy was performed according to a surveillance protocol and when clinically indicated. Aspergillus colonization was defined as a positive culture from bronchoalveolar lavage or two sputum cultures positive for the same Aspergillus species, in the absence of invasive pulmonary Aspergillosis. We found that Aspergillus colonization was strongly associated with BOS and BOS related mortality in Cox regression analyses. Aspergillus colonization typically preceded the development of BOS by a median of 261 days (95% CI 87,520). Furthermore, in a multivariate Cox regression model, Aspergillus colonization was a distinct risk factor for BOS, independent of acute rejection. These data suggest a potential causative role for Aspergillus colonization in the development of BOS post-lung transplantation and raise the possibility that strategies aimed to prevent Aspergillus colonization may help delay or reduce the incidence of BOS.

Isolated invasive Aspergillus tracheobronchitis: a clinical study of 19 cases

Clin Microbiol Infect 2010; 16: 689,695 Abstract Isolated invasive Aspergillus tracheobronchitis (iIATB) is an uncommon clinical form of invasive Aspergillosis in which Aspergillus infection is limited entirely or predominantly to the tracheobronchial tree. In the present study, we retrospectively analyzed the medical records of 19 patients who had histological documented iIATB in the Department of Respiratory Medicine of Changhai Hospital between October 2000 and February 2008. Malignancy was the most common underlying disease, which existed in 14 patients (73.7%) in our series. Most patients had impaired airway structures or defence functions, whereas the systemic immune status was relatively normal. Only three patients (15.8%) had neutropenia. The clinical manifestations and chest radiograph were nonspecific. We classified iIATB into four different forms according to the bronchoscopic features of intraluminal lesions: superficial infiltration type (Type I, n = 4), full-layer involvement type (Type II, n = 2), occlusion type (Type III, n = 6) and mixed type (Type IV, n = 7). Type IV was the largest group in our study, followed by Type III. All patients with iIATB of Type IV had definite airway occlusion. Fourteen patients (73.7%) had a good response to antifungal treatments and five (26.3%) died as a result of the progression of Aspergillosis, all of whom had full-layer invasion of the involved bronchi. In conclusion, we found that iIATB could occur in moderately or non-immunocompromised patients with impaired airway structures or defence functions and may be an early period of invasive pulmonary Aspergillosis. Most of the iIATB patients had a favourable prognosis with early diagnosis and effective antifungal treatment. The morphological features of intraluminal lesions might be of prognostic value.

Zygomycosis , a case report and overview of the disease in India

MYCOSES, Issue 4 2007
Amit Diwakar
Summary A case of zygomycosis caused by Rhizopus oryzae in a diabetic patient previously misdiagnosed as invasive pulmonary aspergillosis and an overview of the disease in India are presented. The case was diagnosed by direct microscopy, histopathologic examination and culture. Following surgical resection of pulmonary cavity under cover of amphotericin B administration, the patient recovered completely. Of 461 cases reported to-date, approximately 70% had been diagnosed at the Postgraduate Institute of Medical Education and Research, Chandigarh, in north India. This may be attributed to better awareness, expertise and infrastructural facilities for mycological diagnosis than to any particular regional preponderance of the disease. Rhino-orbito-cerebral manifestations were the most common feature of zygomycosis (269 cases), followed by cutaneous disease (66 cases), which is in conformity with the pattern prevalent worldwide. The etiologic agents encountered were Rhizopus oryzae, Apophysomyces elegans, Saksenaea vasiformis, Cunninghamella bertholletiae, Absidia corymbifera, Basidiobolus ranarum and Conidiobolus coronatus. In contrast to cases from the developed world where transplant recipients and patients with haematological malignancies seem to be most vulnerable to zygomycosis, the most common risk factor in India was uncontrolled diabetes mellitus. Amphotericin B was the mainstay of various treatment modalities employed. The relevance of a strong clinical suspicion and early diagnosis of zygomycosis for favourable prognosis can hardly be over-emphasised. [source]
