Abstract
Pulmonary complications are common in children following hematopoietic cell transplantation (HCT) and contribute to their morbidity and mortality. Early diagnosis is essential for management and prevention of progression of lung injury and damage. In many cases, diagnosis can be challenging and may require diagnostic imaging and more invasive testing such as bronchoscopy and lung biopsy. We report the case of a 12-year-old girl who developed recurrent episodes of acute respiratory failure requiring intensive care unit admission in the post-HCT phase and describe the diagnostic and multidisciplinary approach for her management. In addition, we review the diagnostic approach of pulmonary complications post-HCT and highlight the utility and risks of bronchoscopy and lung biopsy in these children.

Abstract
BACKGROUND Acute respiratory distress syndrome (ARDS) is one of the pulmonary complications after hematopoietic cell transplantation (HSCT) with a poor prognosis. The effects of corticosteroid therapy in HSCT patients with ARDS have never been described. In this study, we aim to evaluate the effect of corticosteroid on hospital mortality and other outcomes in patients with HSCT and ARDS. METHODS In this bicenter retrospective study, data were collected from patients diagnosed with ARDS and HSCT. Patients were divided into an early high dose steroids group (receiving a cumulative dose ⩾480 mg of methylprednisolone or its equivalent within the first 3 days after ARDS onset) and a no early high dose steroids group. Univariate and multivariate analyses were used to determine the risk factors of hospital mortality. Cox regression was performed to assess the effect of early high dose steroids on patient survival. A propensity score matched cohort was built to validate the results from the original study cohort. RESULTS Two hundred and sixty-four patients were included in the original study cohort; 89 (33.71%) patients received early high dose steroids; these patients had higher ventilator free days at day 28 (7.68 ± 4.32 versus 6.48 ± 4.76, p = 0.046); there was no difference in hospital mortality (64.04% versus 53.14%, p = 0.091). Patients with early high dose steroids had a higher incidence of new onset bacteremia (17.98% versus 4%, p < 0.001) and viremia (13.48% versus 3.43%, p = 0.002). The results were further confirmed in the propensity score matched cohort, except for the improvement of ventilator free days (6.02 ± 5.51 versus 5.57 ± 5.54, p = 0.643). CONCLUSION In this cohort of HSCT patients with ARDS, early high dose coticosteroids had no effect on hospital mortality. In addition, the incidences of new onset bacteremia and viremia were increased after early high dose steroids.The reviews of this paper are available via the supplemental material section.

Abstract
INTRODUCTION Bronchoalveolar lavage (BAL) was previously considered as the standard diagnostic procedure to investigate pneumonia occurring in immunocompromised patients, and it is probably still widely used. However, the development of new microbiological diagnostic tools, applicable to samples obtained non-invasively, leads to questioning of the predominant place of BAL in this situation. BACKGROUND The available studies agree on the acceptable tolerance of BAL performed in immunocompromised patients. Although imperfect, the diagnostic yield of BAL in immunocompromised patients is well established, but it may vary between studies depending on the underlying disease. However, it must also be compared to the yield of non-invasive microbiological tools, now widely available and effective. The position of BAL remains important both for the diagnosis of fungal infections (invasive aspergillosis, pneumocystis pneumonia) and non-infectious lung diseases both of which occur frequently in immunocompromised patients. CONCLUSION The place of BAL in the diagnostic work-up of pneumonia occurring in immunocompromised patients must be considered in the framework of a structured consideration, taking into account the diagnostic performance of non invasive microbiological tests and the broad spectrum of lung diseases occurring in this context.

Abstract
BACKGROUND We describe organisms found in the respiratory tracts of a multicenter cohort of pediatric hematopoietic cell transplant (HCT) recipients with respiratory failure. METHODS Twelve centers contributed up to 25 pediatric allogeneic HCT recipients requiring mechanical ventilation for respiratory failure to a retrospective database. Positive respiratory pathogens and method of obtaining sample were recorded. Outcomes were assessed using Mann-Whitney U test or chi-squared analysis. RESULTS Of the 222 patients in the database, ages 1 month through 21 years, 34.6% had a positive respiratory culture. 105 pathogens were identified in 77 patients; of those, 48.6% were viral, 34.3% bacterial, 16.2% fungal, and 1% parasitic. PICU mortality with a respiratory pathogen was 68.8% compared to 54.9% for those without a respiratory pathogen (P = .045). Those with a positive respiratory pathogen had longer PICU length of stay, 20 days (IQR 14.0, 36.8) vs 15 (IQR 6.5, 32.0), P = .002, and a longer course of mechanical ventilation, 17 days (IQR 10, 29.5) vs 8 (3, 17), P < .0001. Method of pathogen identification, type of pathogen, and the presence of multiple pathogens were not associated with changes in PICU outcomes. CONCLUSIONS In this multicenter retrospective cohort of intubated pediatric post-HCT patients, there was high variability in the respiratory pathogens identified. Type of pathogen and method of detection did not affect PICU mortality. The presence of any organism leads to increased PICU mortality, longer PICU stay, and increased duration of mechanical ventilation suggesting that early detection and treatment of pathogens may be beneficial in this population.

Abstract
Objectives To demonstrate the value of flexible bronchoscopy (FB) and bronchoalveolar lavage (BAL) when determining causes of lung infection in immunocompromised children; to investigate differences in causes and radiological features of lung infections following bone marrow transplantation (BMT) compared to other immunosuppressive conditions; to evaluate the reliability of radiological findings when predicting the pathogen. Methods We retrospectively evaluated 132 immunosuppressed children who underwent FB and BAL because pulmonary complications between January 1999 and May 2014 at the Hacettepe University Hospital Pediatric Pulmonology Unit. Two groups, Group I (n = 106) and Group II (n = 26), consisted of patients who had primary or secondary immunodeficiency and those who were immunosuppressed because BMT, respectively. Radiological findings before FB and macroscopic and microscopic findings of the procedure were evaluated. Results FB and BAL were diagnostic in 86/132 patients (65.1%) and the antimicrobial treatment changed for 75/132 patients (56.8%). The most common pathogen was bacteria (Streptococcus pneumoniae was the leading one). Bacteria were more frequent in Group I than Group II (P = .008). No significant difference in radiological findings between Groups I and II was found. Considering all patients, a significant association was detected between viral pathogens and radiologically interstitial infiltration and a ground‐glass appearance (P = .003). However, no significant association was detected between bacterial and fungal pathogens and the radiological findings. Conclusion In immunosuppressed patients, FB and BAL should be evaluated early for clarifying the causative agents. Then, appropriate treatments can be utilised and the side effects and high cost of unnecessary treatment may be mitigated.

Reduced Risk of Sinusoidal Obstruction Syndrome of the Liver after Busulfan-Cyclophosphamide Conditioning Prior to Allogeneic Hematopoietic Stem Cell Transplantation. Clin Transl Sci 2019; 13:293-300.

Abstract
The aim of this study is to evaluate the incidence of sinusoidal obstruction syndrome (SOS) of the liver and the clinical outcome after hematopoietic stem cell transplantation (HSCT) based on several modifications in our protocols. We retrospectively investigated 372 patients undergoing myeloablative conditioning with oral busulfan (Bu) and cyclophosphamide before allogeneic HSCT during 1990–2015. Patients' supportive care was changed in order to reduce the regimen‐related toxicities. Norethisterone use was terminated in 1998, therapeutic drug monitoring of Bu was initiated in 2000, and the use of liver supportive drugs, such as ursodeoxycholic acid and N‐acetyl‐L‐cysteine, were started in 2002 and 2009, respectively. In total, 26 patients (7.0%) developed SOS at a median of 19 days after transplantation. Of these 26 patients, 20 died at a median of 119 days after HSCT and 102 days after the diagnosis of SOS. The incidence of SOS decreased over time in accordance with the improvements in supportive care. The highest incidence of SOS was during 1995–1999 (16.2%) compared with 2.3% during 2010–2015. Overall survival for patients with SOS was 62%, 46%, and 27% at 100 days, 1 year, and 5 years after HSCT, respectively, compared with 92%, 77%, and 66% for those who did not develop SOS (P < 0.001). In conclusion, the incidence of SOS and related deaths were significantly decreased over the last years. Our institution pursues massive preventative and personalized measures for SOS. This strategy may also be applicable in other conditioning protocols in order to reduce the incidence of SOS and, hence, improve the clinical outcome.

Diagnostic Performance and Safety of Bronchoalveolar Lavage in Thrombocytopenic Haematological Patients for Invasive Fungal Infections Diagnosis: A Monocentric, Retrospective Experience. Mediterr J Hematol Infect Dis 2019; 11:e2019065. [PMID: 31700590 PMCID: PMC6827601 DOI: 10.4084/mjhid.2019.065] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Accepted: 10/14/2019] [Indexed: 01/11/2023] Open
Abstract
Background Although bronchoalveolar lavage (BAL) measurements of galactomannan antigen (GM) seems to be more sensitive than serum testing to detect invasive fungal infection (IFI), a consensus on the most appropriate diagnostic threshold of the BAL GM test is still unclear. Moreover, there is uncertainty as to whether BAL is a safe procedure in patients with hematological malignancies (HM) and thrombocytopenia. Objectives Based on this background, 102 adult patients with HM and associated thrombocytopenia were retrospectively analyzed with the dual aim of 1) determining whether BAL is a safe and feasible procedure; and, 2) identifying the most appropriate threshold for GM positivity in the diagnosis of IFI. Patients/Methods each BAL was considered as one case/patient. One hundred twelve BALs were carried out in 102 HM patients: at the time of the BAL, the median platelet count (PLTs) in all patients was 47×109/L (1–476), and 31 patients (27%) had PLTs< 20×109/L. Results complications from the BAL were infrequent (3.5%) and mild. No bleeding was reported. The BAL GM cut off of >0.8 was associated with the best diagnostic accuracy (sensitivity 72.97% and specificity 80%). Antifungal treatment of patients with BAL GM >0.8 resulted in a clinical-radiological improvement in 35/41 patients (85%). Conclusions BAL was a safe procedure also in thrombocytopenic patients, permitting an IFI diagnosis not otherwise identifiable using EORTC/MSG criteria. Our data suggest that a BAL GM value of>0.8 represents the most useful cut-off in terms of sensibility and specificity. Further prospective studies on a more significant number of patients are needed to confirm these results.

Abstract
Objective: To evaluate the diagnostic value of bronchoalveolar lavage (BAL) for pulmonary complications in patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and its safety. Methods: Patients with pulmonary complications after allo-HSCT underwent BAL. Microbiological smears, culture, PCR of CMV-DNA, EBV-DNA and TB-DNA, macro genomes new generation sequencing (mNGS) techniques were performed to detect pathogens in BAL fluid (BALF) . Results: A total of 73 allo-HSCT patients with 86 times of pulmonary complications enrolled this prospective study. They underwent 132 times of BAL procedures. The clinical diagnoses of 88.4% cases were made based on BALF analysis. Of them, 67 cases (77.9%) had infectious pulmonary complications, including 29 cases (33.7%) of fungal infection, 18 cases (20.9%) of mixed infection, 11 cases (12.8%) of viral infection and 9 cases (10.5%) of bacterial infection. The other 9 cases (10.5%) of non-infectious pulmonary complications included 8 cases (9.3%) of idiopathic pneumonia syndrome (IPS) and 1 case (1.2%) of pulmonary infiltration of lymphoma. The diagnoses of the remaining 10 cases (11.6%) were not determined. The platelet counts of 33 patients were less than 50×10(9)/L before BAL. None of them developed severe bleeding complications during or after BAL. Transient fever occurred in 10 patients after BAL. Blood cultures showed staphylococcal bacteremia in them and anti-infection therapies were effective. No life-threatening complications occurred in all of the patients during or after BAL. Conclusion: BALF analysis was informative for the diagnosis of pulmonary complication and safe for patients with pulmonary complications after allo-HSCT.

Abstract
Objective Since pulmonary complications are a major cause of mortality in patients with hematologic diseases, their rapid detection and treatment are essential. Bronchoalveolar lavage (BAL) is widely performed to diagnose pulmonary infiltrates not evident with non-invasive investigations; however, reports on its clinical benefits for patients with hematologic diseases are limited. The aim of our study was to investigate the utility of diagnostic bronchoscopy with BAL for those patients. Methods We retrospectively reviewed the clinical records of 37 consecutive BAL procedures in 33 adult patients with hematological diseases and pulmonary infiltrates with at least 6 months of follow-up between August 2013 and September 2017 (total 747 BAL procedures). The BAL results, ensuing treatment modifications, treatment outcomes, survival times, and adverse events were evaluated. Results Microbiological findings were detected in 11 (29.7%), even though wide-spectrum antibiotics and antifungal drugs had been empirically administered to most patients (>70%) prior to the bronchoscopy procedure. Overall, 25 of the 37 BAL procedures (67.6%) had some impact on the diagnosis of pulmonary diseases. Patients without specific diagnostic findings from BAL had a significantly poorer survival than those with diagnostic findings via BAL (30-day survival: 33.3% vs. 92.0%; 180-day survival: 8.3% vs. 64.0%). Four patients (12.1%) experienced complications associated with bronchoscopy; there were no procedure-related deaths. Conclusion BAL seems still important for diagnosing pulmonary infiltrates and/or excluding some of the important respiratory tract pathogens in patients with hematological diseases; furthermore, negative specific diagnostic findings from BAL may be associated with poor prognoses.

Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) recipients frequently develop acute respiratory failure (ARF) with pulmonary infiltrates. Molecular- and biomarker-based assays enhance pathogen detection, but data on their yield in this population are scarce. This was a retrospective single-center study of 156 consecutive HSCT recipients admitted to the intensive care unit (ICU) between May 2013 and July 2017. Findings from a microbiologic diagnostic workup using currently available methods on bronchoalveolar lavage (BAL) and blood samples from 66 patients (age, 58 years [range, 45 to 64]; HSCT to ICU, 176 days [range, 85 to 407]) with ARF and pulmonary infiltrates were analyzed. In 47 patients (71%) a causative pathogen was identified (fungal, n = 28; viral, n = 26; bacterial, n = 18). Polymicrobial findings involving several pathogen groups occurred in 20 patients (30%). Culture (12/16, 75%), galactomannan (13/15, 87%), and Aspergillus-PCR (8/9, 89%) from BAL but not serum galactomannan (6/14, 43%) helped to diagnose invasive aspergillosis (n = 16, 24%). Aspergillus-PCR detected azole resistance in 2 cases. Mucorales was found in 7 patients (11%; BAL culture, n = 6; Mucorales-PCR, n = 1). Patients with identified pathogens had higher Simplified Acute Physiology Score II scores (P = .049) and inferior ICU survival (6% versus 37%, P < .01), which largely related to the presence of an invasive fungal infection. Eight patients (12%) had 1 or more viruses with uncertain lung pathogenicity as the sole microbiologic finding. A diagnostic microbiologic workup incorporating molecular- and biomarker-based assays identified pathogens in most HSCT recipients with ARF and pulmonary infiltrates admitted to the ICU. Implications of polymicrobial infection and pathogen patterns in these patients warrant further investigation.

Abstract
Objectives Pulmonary infiltrates in allogeneic hematopoietic stem cell transplant (allo‐HSCT) patients are potentially life‐threatening and require early diagnosis and treatment. We aimed to retrospectively explore the clinical efficacy of polymerase chain reaction (PCR) in conjunction with flexible bronchoscopy (FB) in allo‐HSCT patients with pulmonary infiltrates. Patients and methods We retrospectively reviewed all patients undergoing FB after allo‐HSCT at the Peking University Institute of Hematology from January 2013 to December 2016. We used PCR to detect various viruses in FB specimens, particularly for 27 viruses. Results One hundred forty‐nine diagnostic FBs were performed in 130 patients. The overall diagnostic yield was 58%. Eighty‐nine percent of the patients with a positive FB result were diagnosed with a pulmonary infection. Viruses were the most common infectious diagnosis (70%), followed by fungi (48%), bacteria (38%), and Pneumocystis jirovecii (12%). Multivariate analyses showed that a chest computed tomography (CT) finding of diffuse pulmonary infiltrates (P = .012) and positive results in assisted microbiological and serological analyses (P = .000) predicted a positive FB result. FB results prompted a treatment modification in 61% of cases. Conclusions FB in conjunction with PCR is efficient in the rapid diagnosis and management of pulmonary infiltrates in allo‐HSCT patients.

Abstract
PURPOSE Stem cell transplant (SCT) recipients commonly undergo bronchoalveolar lavage (BAL) collection as an infectious pulmonary work-up. Previous studies report the utility and overall diagnostic yield of fiberoptic bronchoscopy with BAL in this vulnerable population, though none focused purely on microbiologic yield or made comparisons with less invasive means of pathogen detection. We sought to determine and elaborate on the microbiologic yield of BAL in SCT recipients, assess a correlation between BAL studies and less invasive means of pathogen detection, and assess the utility of repeating a BAL within 30 days. METHODS Between January 1, 2009, and July 31, 2013, we reviewed medical records of 125 SCT recipients who underwent 179 BALs. In addition to demographic information and details pertaining to their SCT, a comprehensive review of their microbiologic data was performed and recorded. RESULTS Our study showed an overall BAL microbiologic yield of 40%, despite 92% of patients receiving broad-spectrum antimicrobial therapy at the time of the BAL procedure. CONCLUSIONS Although an initial BAL sample in this population provides crucial microbiologic information, repeating the procedure within 30 days may have minimal additional microbiologic yield. BAL continues to be an essential diagnostic tool in SCT recipients undergoing an infectious pulmonary work-up.

Abstract
Over the past 20 years, considerable healthcare resources have shifted from an inpatient to an outpatient setting. To be in an outpatient setting or at home after allogeneic haematopoietic stem cell transplantation (allo-HSCT) has been shown to be medically safe and beneficial to the patient. In this study we describe patients' experiences of different care settings (hospital or home) and a new life situation during the acute post-transplant phase after HSCT. Semi-structured interviews were conducted with 15 patients (six women and nine men) 29-120 days after HSCT. An inductive qualitative content analysis was performed to analyse the data. The analysis resulted in four categories: To be in a safe place, To have a supportive network, My way of taking control, and My uncertain return to normality. The findings showed that patients undergoing HSCT felt medically safe regardless of the care setting. The importance of a supportive network (i.e. the healthcare team, family and friends) was evident for all patients. Both emotional and problem-focused strategies were used to cope with an uncertain future. Being at home had some positive advantages, including freedom, having the potential for more physical activity, and being with family members. The study highlights some key areas thought to provide more personalised care after HSCT.

Abstract
BACKGROUND Patients treated for hematological malignancies have an increased risk of serious infections. Diagnosis and prompt initiation of therapy are essential. Bronchoalveolar lavage (BAL) is a well-established investigation for identifying the cause of pulmonary infiltrates in immunocompromised patients. The aim of the study was to determine the diagnostic yield of BAL in patients treated for hematological malignancies and how often it contributed to a modification of the anti-infectious therapy. METHODS We reviewed records from 151 consecutive BAL procedures in 133 adult patients with hematological malignancies, treated at a tertiary hematology unit from 2004 to 2013. Extensive microbiological work-ups on BAL samples had been performed according to a standardized protocol. RESULTS A microbiological finding causing the infectious episode could be identified in 59 (39%) cases. In 44 (29%) of the cases, results from BAL had an impact on clinical management either by contributing to a specific diagnosis (25%) or by leading to cessation of ongoing microbiological therapy. The most common diagnoses were invasive pulmonary aspergillosis (IPA) and Pneumocystis jirovecii pneumonia (PJP). Diagnoses of IPA and PJP were based on results from BAL in 65% and 93% of cases, respectively. Several microbiological tests on BAL samples rendered no positive results. Complications were few and mainly mild. CONCLUSION BAL is still important for either verifying or excluding some of the most important respiratory tract pathogens in patients with hematological malignancies, particularly IPA and PJP. Standardized procedures for BAL sampling should be continually revised to exclude unnecessary microbiological tests.

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.

Abstract
Stenotrophomonas maltophilia (S. maltophilia) is a globally emerging Gram-negative bacillus that is widely spread in environment and hospital equipment. Recently, the incidence of infections caused by this organism has increased, particularly in patients with hematological malignancy and in recipients of hematopoietic stem cell transplantation (HSCT) having neutropenia, mucositis, diarrhea, central venous catheters or graft versus host disease and receiving intensive cytotoxic chemotherapy, immunosuppressive therapy, or broad-spectrum antibiotics. The spectrum of infections in HSCT recipients includes pneumonia, urinary tract and surgical site infection, peritonitis, bacteremia, septic shock, and infection of indwelling medical devices. The organism exhibits intrinsic resistance to many classes of antibiotics including carbapenems, aminoglycosides, most of the third-generation cephalosporins, and other β-lactams. Despite the increasingly reported drug resistance, trimethoprim-sulfamethoxazole is still the drug of choice. However, the organism is still susceptible to ticarcillin-clavulanic acid, tigecycline, fluoroquinolones, polymyxin-B, and rifampicin. Genetic factors play a significant role not only in evolution of drug resistance but also in virulence of the organism. The outcome of patients having S. maltophilia infections can be improved by: using various combinations of novel therapeutic agents and aerosolized aminoglycosides or colistin, prompt administration of in vitro active antibiotics, removal of possible sources of infection such as infected indwelling intravascular catheters, and application of strict infection control measures.

Abstract
Bronchoalveolar lavage (BAL) has been a useful initial diagnostic tool in the evaluation of pulmonary complications after hematopoietic stem cell transplantation (HSCT); however, the diagnostic sensitivity, prevalence, and outcome after BAL versus lung biopsy (LB) in pediatric HSCT patients remains to be determined. We reviewed 193 pediatric HSCT recipients who underwent a total of 235 HSCTs. Sixty-five patients (34%) underwent a total of 101 BALs for fever, respiratory distress, and/or pulmonary infiltrates on chest radiograph and/or computed tomography scan. The 1-year probability of undergoing BAL was 43.0% after allogeneic stem cell transplantation (alloSCT) and 8.5% after autologous stem cell transplantation (autoSCT) (P = .001). Sixteen of the 193 patients (8%) patients underwent 19 LBs. The probability of undergoing LB at 1 year after HSCT was 9.3%. No grade III or IV adverse events related to either procedure were observed. Of the 101 BALs performed, 40% (n = 40) were diagnostic, with a majority revealing a bacterial pathogen. Among the 19 LBs performed, 94% identified an etiology. In multivariate analysis, myeloablative conditioning alloSCT conferred the highest risk of requiring a BAL (hazard ratio [HR],8.5; P = .0002). The probability of 2-year overall survival was 20.2% in patients who underwent BAL, 17.5% for patients who underwent biopsy, and 67.4% for patients who had neither procedure. In multivariate analysis, only the requirement of a BAL was independently associated with an increased risk of mortality (HR, 2.96; P < .0001). In summary, in this cohort of pediatric HSCT recipients, BAL and LB were used in approximately 35% and 8% of pediatric HSCTs with diagnostic yields of approximately 40% and 94%, respectively, and were both associated with poor long-term outcomes.

Abstract
Infections are one of the most common complications in patients diagnosed with leukemia and serve as a major obstacle to treatment. Through the early 1970s, infections were the most common cause of death in patients diagnosed with acute leukemia, but improvement in treatment and supportive care over the past few decades, coupled with expanded prophylaxis and prevention regimens, have led to reduction in both the frequency and severity of infections. Regardless, due in part to an aging cancer population and the diversity of cancer treatments and procedures, infectious diseases remain a major cause of morbidity and mortality in patients with leukemia.

Bronchoalveolar lavage (BAL) is commonly used to help diagnose and characterize pneumonia in these patients. Mini-BAL is a less-invasive, less-costly and less-cumbersome diagnostic tool than BAL. OBJECTIVES In this study, we compared the diagnostic value of BAL and mini-BAL in the evaluation of pneumonia in immunocompromised patients with respiratory failure. METHODS Sixty-four respiratory samples were collected from 32 immunocompromised patients admitted to our respiratory intensive care unit with a clinical diagnosis of pneumonia and respiratory failure requiring invasive mechanical ventilation. A single BAL sample and a single mini-BAL sample were collected from each patient. Samples were examined for bacteriologic, mycologic, mycobacteriologic, and viral organisms. RESULTS The mean age of the patients was 56.0 ± 14.4 years. Of the 32 BAL samples, bacterial isolates were detected in 11 patients (34.4%) and on the other hand bacterial isolates were detected in 10 patients (31.3%) of the mini-BAL samples. Fungal isolates were detected in 11 patients (34.4%) from BAL samples and 13 patients (40.6%) from mini-BAL samples. Our analysis demonstrated a strong positive correlation between the results of BAL and mini-BAL testing (r = 0.850 and r = 0.821, respectively). CONCLUSION In this study, we demonstrated a strong correlation between the isolation rates of bacteria and fungi in BAL and mini-BAL samples obtained from immunocompromised patients with pneumonia and respiratory failure. The data strongly support the use of mini-BAL sampling in such patients as a less-invasive, less-costly and simpler alternative to traditional BAL.

C-reactive protein levels before reduced-intensity conditioning predict outcome after allogeneic stem cell transplantation. Int J Hematol 2010; 92:161-7. [PMID: 20577834 DOI: 10.1007/s12185-010-0632-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2010] [Revised: 04/19/2010] [Accepted: 06/07/2010] [Indexed: 01/22/2023]
Abstract
The prognostic value of CRP levels before conditioning for allogeneic stem-cell transplantation (ASCT) was evaluated. Reduced-intensity conditioning (RIC) was given to 205 patients and conventional myeloablative conditioning (MAC) to 299 patients. Most patients had an HLA-compatible related or unrelated donor. There were 287 males and 216 females, median age 36 (1-69) years. Most patients received peripheral blood stem cells. Increased CRP levels (>10 mg/L) were detected in 129 patients (26%). Overall survival (OS) and transplant-related mortality (TRM) were worse for RIC patients with elevated CRP (67 vs. 43%, p = 0.005, and 16 vs. 30%, p = 0.036) while no difference was seen in MAC patients. An infection at the start of conditioning was seen in 27 RIC patients. We identified a subgroup of patients with an infection and elevated CRP (n = 16) and these patients had the worst outcome. In multivariate analysis, both infection and elevated CRP was the strongest factor associated with OS (HR 3.27, p < 0.001) and TRM (HR 4.35, p < 0.001). No correlation between any outcome variable and CRP was seen in MAC-treated patients. CRP may be a good prognostic factor for outcome after RIC and ASCT. It should be analyzed before conditioning, especially in patients with coexisting infection since patients with increased CRP and infection seem to have a very poor outcome after ASCT.
