Clinical Significance of Post-Treatment Viral Load of Cytomegalovirus in Patients with Hematologic Malignancies

ConclusionsIn patients with hematologic diseases suffering CMV viremia, failure to eradicate viremia after antiviral therapy indicates a higher chance of mortality and can be regarded as a useful indicator in evaluating the patient’s long-term prognosis.

AbstractObjectivesThe aims of this study were to compare the high-resolution computed tomography (HRCT) findings of pulmonary infections in immunocompromised patients and to assess the usefulness of HRCT in the differential diagnosis of these infections.MethodsA total of 345 immunocompromised patients with pulmonary infections were included in this study. The diagnoses of the patients consisted of bacterial pneumonia (123 cases), pneumocystis pneumonia (PCP) (105 cases), fungal pneumonia (80 cases), tuberculosis (15 cases), cytomegalovirus pneumonia (11 cases), and septic embolism (11 cases). Two chest radiologists retrosp...

In this study they also showed PTX3 localized in NETs formed after neutrophil activation (5). Proteomics analysis revealed that PTX3 forms complexes with two anti-microbial proteins [azurocidin (AZU1) and myeloperoxidase (MPO)] associated to NETs (30). More recently, PTX3 localization in NETs has been confirmed, and the colocalization with AZU1 and MPO has been defined more accurately (31). Further investigation will be needed to understand the involvement of PTX3 interaction with AZU1 and MPO in their antibacterial role during NET formation. Regulation of Complement Activation PTX3 interaction with microorganisms is not...

BackgroundHigh dose chemotherapy and autologous stem cell transplant (ASCT) results in cure for up to 50% of patients with Hodgkin (HL) and aggressive non-Hodgkin lymphoma (NHL) that relapse after initial treatment with chemo-immunotherapy. Despite improvements in supportive care and patient selection, death after ASCT remains a concern due to progressive disease, infection, and other treatment- and non-treatment-related causes. We evaluated causes and predictors of death in patients undergoing ASCT for HL and NHL.MethodsWe conducted a single-institution, retrospective study of all patients with HL and NHL including diffus...

CONCLUSIONS: The risk of death due to infectious causes after kidney transplantation in Finland dropped by one half since the 1990s. Common bacterial infections remained the most frequent cause of infection-related mortality, whereas opportunistic viral, fungal, or unconventional bacterial infections rarely caused deaths after kidney transplantation.

Mannose‐binding lectin (MBL) is synthesized by the liver and binds to microbes. MBL2 gene polymorphisms produce intermediate/low/null or normal MBL serum levels (MBL‐deficient or MBL‐sufficient phenotypes, respectively). We aimed to evaluate the incidence and severity of infection, rejection, and survival within 1 year after liver transplantation (LT) according to donor and recipient MBL2 gene polymorphisms. A repeated‐event analysis for infection episodes (negative binomial regression, Andersen–Gill model) was performed in 240 LTs. Four hundred twenty‐eight infectious episodes (310 bacterial, 15 fungal, 65...

Komanduri Despite the refinements in molecular methods for the detection of cytomegalovirus (CMV) and the advent of highly effective preemptive strategies, CMV remains a leading cause of morbidity and mortality in hematopoietic cell transplant (HCT) recipients. CMV can cause tissue-invasive disease including pneumonia, hepatitis, colitis, retinitis, and encephalitis. Mortality in HCT recipients with CMV disease can be as high as 60%. CMV infection has been associated with increased risk o...

Opportunistic infections are a major cause of morbidity and mortality in severely immunocompromised patients, such as those receiving chemotherapy or biological therapies, patients with haematological malignancy, aplastic anaemia or HIV infection, and recipients of solid-organ or stem cell transplants. The type and degree of the immune defect dictate the profile of potential opportunistic pathogens; T-cell-mediated defects increase the risk of viral (cytomegalovirus, respiratory viruses) and Pneumocystis jirovecii infections, whereas neutrophil defects are associated with bacterial pneumonia and invasive aspergillosis.

​BY MARGARET MARY S. LANDEL, DO; &CARLA DUGAS, DOA 59-year-old otherwise healthy man presented with an upper respiratory illness of four weeks' duration. His initial presentation to his primary care physician one month prior included a nonproductive cough and low-grade fever, which lasted approximately two weeks until his internist ordered a chest x-ray. That showed a 3 cm well-circumscribed right lower lobe lesion, and was followed by a contrast enhanced chest CT. The chest CT was concerning for pulmonary neoplasm, and he received an interventional radiology-guided biopsy of the lesion. Results were still pending at...

CONCLUSIONS: In this study, we hypothesized that daily use of low-dose valacyclovir (1000 mg/d) is not only sufficient for cytomegalovirus prophylaxis but also beneficial in terms of cost. PMID: 26976362 [PubMed - as supplied by publisher]
