Abstract
Background Mature blood cells can be differentiated from hematopoietic stem cells; thus, the latter can play a crucial role in maintaining defense against different microorganisms. Thus, hematopoietic stem cell transplantation is one of the most important lines of immunotherapy. Major systemic complications may occur post transplantation and could be fatal. Pulmonary complications include infectious and non-infectious complications. The aim of this study was to detect the pulmonary complications in allogeneic stem cell transplantation patients. Results We studied 20 patients after transplantation of allogeneic stem cells with regular follow-up in outpatient clinic of hematology department of Alexandria Main University Hospital. All the studied patients were subjected to history taking, plain x-ray chest PA view, CT chest, complete blood count, serum creatinine, liver enzymes, and serum cytomegalovirus (CMV) detection by antibodies IgG and IgM. Regarding sputum sampling, 7 patients’ samples (35%) were obtained either spontaneously or by induction via hypertonic saline 3%. One patient (5%) had miniBAL done, while bronchoalveolar lavage using fiber optic bronchoscopy was done for 2 patients (10%). Samples could not be obtained from the remaining patients. Samples were analyzed for culture for bacteria, Pneumocystis jiroveci using immunofluorescence test, CMV PCR, fungal culture, and smear for acid fast bacilli (AFB). Among the examined patients, 2 patients (20%) had pulmonary bacterial infection including streptococcus and multidrug-resistant strain of Klebsiella, 3 patients (30%) had pulmonary candida infection, and one patient (10%) had positive result of pulmonary CMV of low count which was considered insignificant. None of our patients had positive results for pulmonary tuberculosis nor Pneumocystis jiroveci. Six patients (30%) had CMV in serum; 3 patients (15.8%) had manifested CMV reactivation. One patient (5%) of our patients had pulmonary graft versus host disease GVHD. One patient (5%) had died during our study course within 12 days post-transplantation due to ARDS followed by multiple organ failure. Conclusion The prevalence of pulmonary infectious complications after allogenic stem cell transplantation was 50% of all studied patients, while 5% of the studied patients presented with non-infectious pulmonary complications.

[PMID: 30808314 PMCID: PMC6390608 DOI: 10.1186/s12890-019-0801-2] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Accepted: 02/04/2019] [Indexed: 02/08/2023] Open
Abstract
Background Bronchoalveolar lavage (BAL) is utilized for diagnosing lung infiltrates in immunocompromised. There is heterogeneity in the data and reported diagnostic yields range from 26 to 69%. Therefore, selection criteria for BAL to maximize yield and minimize complications are unclear. Objectives of this study were to determine the diagnostic yield and complication rate of BAL in immunocompromised patients presenting with lung infiltrates, and identify factors impacting these outcomes. Exploratory aims included characterization of pathogens, rate of treatment modification and mortality. Methods Retrospective study from January 2012 to December 2016. Patients on mechanical ventilation were excluded. Positive diagnostic yield was defined as confirmed microbiological or cytological diagnosis. Results A total of 217 patients were recruited (70.1% male and mean age: 51.7 ± 14.6 years). Diagnostic yield was 60.8% and complication rate 14.7%. Complications (hypoxemia and endobronchial bleeding) were all sell-limiting. Treatment modification based on BAL results was 63.3%. In 97.0% an infectious aetiology was identified. HIV infection (OR 5.304, 95% CI 1.611–17.458, p = 0.006) and severe neutropenia (OR 4.253, 95% CI 1.288–14.045, p = 0.018) were associated with positive yield. Leukemia (OR 0.317, 95% CI 0.102–0.982, p = 0.047) was associated with lower yield. No factors impacted complication rate. Overall mortality (90-day) was 17.5% and in those with hematologic malignancy, it was 28.3%. Conclusion BAL retains utility in diagnosis of immunocompromised patients with lung infiltrates. However, patients with hematologic malignancy have a high mortality and alternative sampling should be considered because of poor results with BAL. Trial registration ClinicalTrials.gov identifier NCT01374542. Registered June 16, 2011.

Abstract
PURPOSE The objective of this study was to describe the diagnostic yield and complication rate of bronchoalveolar lavage (BAL) and lung biopsy in the evaluation of pulmonary lesions in patients with cancer and recipients of hematopoietic stem-cell transplantation (HSCT). METHODS We conducted a systematic literature review and performed electronic searches of Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials. Studies were included if patients had cancer or were recipients of HSCT, and if they underwent BAL or lung biopsy for the evaluation of pulmonary lesions. Only English language publications were included. RESULTS In all, 14,148 studies were screened; 72 studies of BAL and 31 of lung biopsy were included. The proportion of procedures leading to any diagnosis was similar by procedure type (0.53 v 0.54; P = .94) but an infectious diagnosis was more common with BAL compared with lung biopsy (0.49 v 0.34; P < .001). Lung biopsy more commonly led to a noninfectious diagnosis (0.43 v 0.07; P < .001) and was more likely to change how the patient was managed (0.48 v 0.31; P = .002) compared with BAL. However, complications were more common with lung biopsy (0.15 v 0.08; P = .006), and procedure-related mortality was four-fold higher for lung biopsy (0.0078) compared with BAL (0.0018). CONCLUSION BAL may be the preferred diagnostic modality for the evaluation of potentially infectious pulmonary lesions because of lower complication and mortality rates; thus, choice of procedure depends on clinical suspicion of infection. Guidelines to promote consistency in the approach to the evaluation of lung infiltrates may improve clinical care of patients.

Utility of flexible bronchoscopy in the evaluation of pulmonary infiltrates in the hematopoietic stem cell transplant population -- a single center fourteen year experience. Arch Bronconeumol 2013; 49:189-95. [PMID: 23455477 DOI: 10.1016/j.arbres.2012.11.012] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2012] [Revised: 11/05/2012] [Accepted: 11/27/2012] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Pulmonary infiltrates are common within the hematopoietic stem cell transplant (HSCT) population and unfortunately portend an increased mortality. Bronchoscopy is often utilized as an initial diagnostic tool, but the literature supporting its diagnostic utility and effect on clinical management varies significantly. The aim of this study was to investigate the diagnostic ability, complication rate, and clinical impact of flexible bronchoscopy (FB) in evaluating pulmonary infiltrates in a large HSCT population. PATIENTS AND METHOD Retrospective review of all patients undergoing FB after HSCT in the Bone Marrow Transplant Unit from 1996 to 2009. RESULTS FB was performed 162times in 144patients with pulmonary infiltrates yielding positive results in 52.5%. The most common positive results were bacterial pneumonia (31%), fungal pneumonia (15%), and alveolar hemorrhage (11%). Treatment changes occurred in 44% of patients after FB. Treatment changes included antibiotic modification (59%), addition of corticosteroids (21%), antifungal modification (12%), and antiviral modification (7%). The overall complication rate associated with FB was 30%, although 84% of these complications were considered minor. CONCLUSIONS FB in patients with pulmonary infiltrates after HSCT should still be considered a valuable tool in the evaluation and management of pulmonary infiltrates in the HSCT population. Future prospective, multicenter randomized studies are needed to evaluate the overall clinical impact that bronchoscopic results and management changes have in this unique population.
