Although post-transplant lymphoproliferative disorder (PTLD) is the second most common type of cancer in kidney transplantation (KT), plasma cell neoplasia (PCN) occurs only rarely after KT, and little is known about its characteristics and evolution. We included twenty-two cases of post-transplant PCN occurring between 1991 and 2013. These included 12 symptomatic multiple myeloma, eight indolent myeloma and two plasmacytomas. The median age at diagnosis was 56.5 years and the median onset after transplantation was 66...

Pyoderma gangrenosum (PG) is a chronic inflammatory disease of unknown cause that presents as an inflammatory and ulcerative disorder of the skin. PG is often associated with an underlying systemic disease. However, the frequencies of the underlying diseases are unclear in Japanese patients. In this retrospective, observational study, all patients diagnosed with PG who visited dermatology departments of nine regional hospitals in and around Ibaraki Prefecture were collected from 1982 to 2011 or 2014. The diagnoses of PG were based on the characteristic clinical and histological appearances and ruling out of infection...

BACKGROUND: Bone Marrow Transplantation(BMT) is used to treat children with various hematologic, oncologic and metabolic diseases. While the treatment is lifesaving, it is also found to be related with anxiety, posttraumatic stress disorder, depression and psychosocial problems both in children and parents. METHODS: The aim of this study was to investigate psychopathology in pediatric BMT survivors and their mothers compared to the healthy controls. All children were interviewed using Kiddie Schedule for Affective Disorders and Schizophrenia for assessing the life-long psychopathology...

Patients with overgrowth and complex vascular malformation syndromes, including Proteus syndrome have an increased risk of thromboembolism. Proteus syndrome is a mosaic, progressive overgrowth disorder involving vasculature, skin, and skeleton, and caused by a somatic activating mutation in AKT1. We conducted a comprehensive review of the medical histories and hematologic evaluations of 57 patients with Proteus syndrome to identify potential risk factors for thrombosis. We found that six of ten patients, who were deceased, died secondary to deep venous thrombosis and/or pulmonary embolism...

Direct oral anticoagulants (DOACs) have been approved to treat and prevent thrombotic events. However, they are not yet labeled for use in patients with active cancers. Myeloproliferative neoplasms (MPNs) are clonal chronic disorders with a high incidence of thrombotic events, for which low-dose aspirin (LDA) is the standard drug treatment. We analyzed efficacy and safety of DOACs prescription in patients treated for MPNs. An MPN database, the OBENE registry, was established at our institution. We collected biological and clinical data from diagnosis to last follow-up for every patient included in this study...

Acetazolamide is a carbonic anhydrase (CA) inhibitor sometimes used as a respiratory stimulant for patients with COPD with the goal of improving oxygenation, reducing carbon dioxide retention and aiding liberation from mechanical ventilation and/or attempting to correct a metabolic alkalosis. However, the net effect of CA inhibition is multifactorial and complex since CA is inhibited in many tissues that may negatively affect the patient with lung disease. The full impact of acetazolamide and other CA inhibitors depends critically on dosing, age, and pulmonary, renal, hepatic, hematological, and respiratory muscle function and reserves...

Multiple myelomas is a neoplastic plasma cell disorder that accounts for one percent of all cancers and 13% of hematologic malignancies. Although primarily known to be a bone marrow disorder, it can metastasize to extramedullary sites or it can present as a solitary extramedullary plasmacytoma. Primary pleural effusion from myeloma is rare, occurring in less than one percent of the patients. The following case report highlights a case of bilateral pleural effusion, directly attributable to multiple myeloma after other causes were ruled out...

Precursor B cell acute lymphoblastic leukemia (B-ALL) is a B cell-derived, malignant disorder with the highest incidence among children. In addition to the genetic abnormality, a dysregulated immune system also has an important role in the pathogenesis of B-ALL. Myeloid-derived suppressor cells (MDSCs) represent one of the key drivers in immune tolerance against tumor cells, including various solid tumors and hematologic malignancies. The role of MDSCs in B-ALL remains poorly understood. Here, we showed that the granulocytic (G)-MDSC population was significantly elevated in both the peripheral blood and BM of patients with B-ALL, when compared with age-matched healthy controls...

BACKGROUND: Systemic lupus erythematosus (SLE) is a genetically complex rheumatic disease characterized by heterogeneous clinical manifestations of unknown etiology. Recent studies have suggested the existence of a genetic basis for SLE heterogeneity. The objective of the present study was to identify new genetic variation associated with the clinically relevant phenotypes in SLE. METHODS: A two-stage pathway-based approach was used to identify the genetic variation associated with the main clinical phenotypes in SLE...

Helicobacter pylori is a spiral-shaped bacterium that grows in the digestive tract and may be present in more than half of the world's population. The clinical features of Helicobacter pylori range from asymptomatic gastritis to gastrointestinal malignancy. Mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade B-cell marginal zone lymphoma and Helicobacter pylori has been detected in more than 75% of the patients with MALT lymphoma. Many tests for the detection of Helicobacter pylori are available, including antibody tests, urea breath tests, stool antigen tests and endoscopic biopsies...

Gastrointestinal amyloidosis (GIA), a protein deposition disorder, represents a complex common pathway that encompasses multiple etiologies and presentations. It represents a significant diagnostic and treatment challenge. The disease results from the deposition of insoluble extracellular protein fragments that have been rendered resistant to digestion. GIA can be acquired or genetic, and most commonly results from chronic inflammatory disorders (AA amyloidosis), hematologic malignancy (AL amyloidosis), and end-stage renal disease (Beta-2 amyloidosis)...

Chronic myelomonocytic leukemia (CMML) is a complex clonal hematological disorder classified among myelodysplastic/myeloproliferative neoplasms (MDS/MPNs). Prognosis is poor and there is a lack of effective treatments. The hypomethylating agent decitabine has shown activity against MDS and elderly acute myeloid leukemia, but there is little data focusing specifically on its efficacy in CMML. In this prospective, phase 2 Italian study, CMML patients received i.v. decitabine 20 mg/m(2)/day on Days 1 to 5 of a 28-day treatment cycle...

Myelodysplastic syndromes (MDS) represent a heterogeneous group of hematologic disorders characterized by cytopenia(s) and predisposition to leukemic progression. An immune dysregulation and an aberrant bone marrow microenvironment seem to be key elements in the physiopathological process of MDS. In order to evaluate a possible association between susceptibility and clinic-pathologic features, we genotyped 153 MDS patients for functional cytokine polymorphisms: TNF (-308 G/A), IFNG (+874 A/T and +875 CAn), IL6 (-174 G/C), and TGFB1 (+869 C/T and +915 G/C)...

As our technological capacities improve, genomic testing is increasingly integrating into patient care. The field of clinical hematology is no exception. Genomic testing carries great promise, but several ethical issues must be considered whenever such testing is performed. This review addresses these ethical considerations, including issues surrounding informed consent and the uncertainty of the results of genomic testing; the challenge of incidental findings; and possible inequities in access to and benefit from such testing...

As individuals with germline predisposition to hematologic malignancies are diagnosed with increasing frequency, the need for clinical surveillance has become apparent. Unfortunately, few prospective data are available, so recommendations are based on collective experience and expert consensus. There is general agreement to advocate for expert consultation or referral of patients to centers with expertise in these syndromes, since presentations and disease progression can be subtle, and treatment strategies must be tailored...

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis seen in association with systemic disorders including hematologic malignancies. Hairy cell leukemia (HCL) however, is an unusual association of PG. We describe a 49-year old lady who presented to our hematology clinic with easy fatiguability and ulcerative skin lesions of 6 months duration. Examination revealed pallor and massive splenomegaly. Indurated, ulcerated lesion with undermined edges and necrotic base was observed on left thigh. Investigations revealed pancytopenia and bone marrow examination identified typical hairy cells...

PURPOSE OF REVIEW: Patient-derived tumor xenografts (PDTXs) have emerged as powerful platforms in medical oncology. A plethora of PDTXs were generated to study solid cancers, but limited data are as yet available on hematological diseases. The aim of this review is to describe the state of art of lymphoma PDTXs, discussing future directions for the development of integrated/personalized cancer programs. RECENT FINDINGS: In the last decades, several PDTXs of lymphoproliferative disorders have been produced...

Practical relevance: Hematologic disorders are relatively common in cats, as inflammatory, immune-mediated and infectious diseases have the potential to impact erythroid, myeloid and thrombopoietic lines within the bone marrow. Clinical challenges: Clinicians often benefit from information obtained from bone marrow cytology and histopathology in diagnosing hematologic disorders in feline patients. However, these sampling procedures are ones that many veterinarians are intimidated by and thus not comfortably performing in clinical practice...

Invasive fungal disease(IFD) is a common yet highly lethal complication in patients with hematological malignancies receiving chemotherapy or stem cell transplantation, as well as immune suppressive conditions including aplastic anemia and other malignancies. According to the diagnostic criteria, patients are defined as proven, probable, possible and undefined IFD based on the evidence provided by histopathologic/cytologic, culture, radiographic and biomarker examinations. For the management of IFD, the major treatment strategies consist of prophylaxis, empirical, diagnostic-driven and target therapy...
