OBJECTIVES: We aimed to describe the current time to positivity (TTP) of blood cultures in onco-hematological patients with febrile neutropenia. We assessed the probability of having multidrug-resistant gram-negative bacilli (MDR-GNB) bloodstream infection (BSI) 24h after cultures were taken, to use this information for antibiotic de-escalation strategies. METHODS: BSI episodes were prospectively collected (2003-2017). When a patient experienced more than one BSI, only one episode was randomly chosen...

Neutropenic patients with hematological diseases are prone to severe infections. Granulocyte transfusion therapy (GTX) is considered as a logical therapeutic approach for these problems. However, the efficacy and complications of GTX have not been well identified. We retrospectively analyzed the clinical outcomes of GTX therapy in our hospital from 2009 to 2015. After 117 granulocyte transfusions for 47 patients, 72.3% of these patients' infections were effectively improved, and the overall survival rates at 30 and 120 days were 66...

Helicobacter pylori ( H. pylori ) infection is very common and affects approximately half of the world population. It causes gastric diseases, but some authors have reported an association of H. pylori infection with other systemic manifestations beginning in 1994. The list of potential effects of H. pylori outside the stomach includes a number of extragastric manifestations and we focused on neurological, dermatological, hematologic, ocular, cardiovascular, metabolic, allergic, and hepatobiliary diseases. This review discusses these important reported manifestations that are not related to the gastrointestinal tract...

Visceral leishmaniasis is an infectious disease that infects and multiplies in macrophages of the liver, spleen, and bone marrow. The most common clinical features are fever, splenomegaly, and anemia. Anemia, leucopenia, and thrombocytopenia are the main hematologic abnormalities commonly seen in visceral leishmaniasis. These findings can be seen in several types of hematologic disorders. The findings are similar to most hematologic disorders and so may make diagnosis problematic. It is difficult to confirm when it is seen except in epidemiologic areas...

BACKGROUND: Quizartinib, an inhibitor of class III receptor tyrosine kinases (RTKs), is currently in phase 3 development for the treatment of acute myeloid leukemia (AML) bearing internal tandem duplications in the FLT3 gene. Aberrant RTK signaling is implicated in the pathogenesis of a variety of solid tumors, suggesting that inhibiting quizartinib-sensitive RTKs may be beneficial in precision cancer therapy. METHODS: This was a phase 1, open-label, modified Fibonacci dose-escalation study of orally administered quizartinib in patients with advanced solid tumors whose disease progressed despite standard therapy or for which there was no available standard treatment...

Type I interferons (IFNα/β) regulate diverse aspects of host defense, but their impact on hematopoietic stem and progenitor cells (HSC/HSPCs) during infection remains unclear. Hematologic impairment can occur in severe infections, thus we sought to investigate the impact of type I IFNs on hematopoiesis in a tick-borne infection with a virulent ehrlichial pathogen that causes shock-like disease. During infection, IFNα/β induced severe bone marrow (BM) loss, blunted infection-induced emergency myelopoiesis, and reduced phenotypic HSPCs and HSCs...

Invasive fungal infections are a common life-threatening disease and a major cause of morbidity, particularly in patients with malignancies, and Candida spp. is the most common isolated fungi in bloodstream. Candidemia is the focus of this review, which covers an approach to diagnosis and treatment, with an emphasis on patients with malignancies. Acute leukemia, lymphoma or myelodysplastic syndrome, are the most common hematological malignancies associated with candidemia, while among solid tumors gastrointestinal cancer has the majority of fungemia cases...

Chronic neutropenia is a rare hematological entity characterized by isolated neutropenia without anemia or thrombocytopenia. The diagnostic criteria and classification of chronic neutropenia have been more elusive in adult cases than pediatric cases. We herein propose the Reference Guide for Adult Chronic Neutropenia. In this guide, diagnosis of chronic neutropenia is based on recurrent or continuous neutropenia defined by absolute neutrophil count (ANC) less than 1,500/µl for over three or more months. Severity of chronic neutropenia is defined as follows: severe, ANC <500/µl; moderate, ANC between 500 and 1,000/µl; mild, ANC between 1,000 and 1,500/µl...

Preliminary evaluation of qualitative and semi-quantitative clinical laboratory measurements is a prerequisite for the accreditation of clinical laboratories, according to the French committee of accreditation guidelines following the European reference standard EN ISO 15189. Numerous papers have been published regarding biochemistry, hematology or immunology. However, data are still lacking for molecular biology. We report our experience and present the performance characteristics of Allplex™ STI Essential real time PCR assay for the detection of seven pathogens, among which some are systematically responsible of sexually-transmitted infections...

Hemophagocytic lymphohistiocytosis (HLH) is a highly fatal, hyperinflammatory syndrome in adults triggered by an underlying illness in most cases. As such, suspicion of HLH dictates further investigation to identify the HLH trigger and determine treatment. HLH is clinically challenging due to diverse presentations and underlying triggers, provider unfamiliarity, and bleeding complications. Clinically, we observed diagnostic error from incorrect testing and cognitive biases (interleukin-2 confused with soluble interleukin-2 receptor and natural killer cell quantification confused with functional assays)...

BACKGROUND: Revision total joint arthroplasties (TJAs) have been empirically associated with significant postoperative morbidity and mortality. Red blood cell distribution width (RDW), a frequently measured hematological parameter, has been shown to predict mortality in hip fracture patients. However, its utility in risk-stratifying patients before revision TJA remains unknown. The aim of this study was to investigate the possible relationship between preoperative RDW levels and outcome of revision arthroplasty in terms of mortality, adverse outcomes, and length of hospital stay...

There has been a progressive rise in the incidence of blood stream infections (BSI) caused by multidrug-resistant Gram-negative organisms (MDR GN), which cause increased morbidity and mortality. For this reason, recent studies have focused on risk factors of acquisition of carbapenemase-producing Enterobacteriaceae and extended-spectrum beta-lactamase producers. However, there is limited data on risk factors for BSI caused by AmpC-producing Enterobacteriaceae (AmpC EC), especially in low prevalence settings such as Australia...

Sweet's syndrome is a rare dermatosis with little-known pathogenesis, associated with some clinical conditions such as infections, autoimmune diseases, inflammatory bowel diseases, vaccination, medications and neoplasms. Hematologic malignancies are the diseases most related to paraneoplastic Sweet's syndrome, but this clinical entity can also be found occasionally in some solid tumors, including genitourinary tract tumors. We report a rare case of paraneoplastic Sweet's syndrome associated with the diagnosis of cervical cancer...

Cancers induced by human papillomavirus (HPV) infection remain a significant public health threat, fueling the study of new therapies. Laurel (Laurus nobilis) compounds and extracts recently showed in vitro activity against HPV-transformed cell lines. This work aims to evaluate the in vivo efficacy and hepatic toxicity of a laurel extract in a transgenic mouse model of HPV16-induced cancer. The extract was administered in drinking water (20 mg per animal per day) for three consecutive weeks, using four experimental groups (n = 10) (group I: HPV16-/- without treatment, group II: treated HPV16-/-, group III: HPV16+/- without treatment and group IV: treated HPV16+/-)...

Feline lower urinary tract diseases are known to be life threatening conditions in cats, especially when they occur as obstructive diseases in males. Early diagnosis and treatment is necessary, otherwise it may lead to death. A 3-year-old male Persian cat was referred to the clinic with a history of anuria, lethargy, loss of appetite and exploratory cystotomy 6 months ago due to urethral obstruction following urolithiasis. Urinary bladder was enlarged and painful on palpation and urine accumulation was observed in ultrasonography...

Dear Editor, Subcutaneous granuloma annulare (SGA) is considered a rare clinical variant of granuloma annulare, a common self-healing chronic inflammatory disorder that may appear in childhood as well as in adult age (1-3). A 29-year-old female patient reported the onset of several small subcutaneous nodules on the dorsal aspect of the second interphalangeal joint of the left medius finger and the left elbow, accompanied by vague joint pain, had occurred 13 years ago. Specific markers for rheumatoid arthritis were negative, leading to a diagnosis of sero-negative rheumatoid arthritis, for which treatment with methotrexate was initiated...

Background: Among the severe malaria syndromes, severe malarial anemia (SMA) is the most common, whereas cerebral malaria (CM) is the most lethal. However, the mechanisms that lead to CM and SMA are unclear. Methods: We compared transcriptomic profiles of whole blood obtained from Ugandan children with acute CM (n=17) or SMA (n=17) and community children without Plasmodium falciparum infection (n=12) and determined the relationships between gene expression, hematological indices, and relevant plasma biomarkers...
