The Bloody Crossroads: Interactions between Periodontitis and Hematologic Diseases.

Periodontitis is a common oral condition that can have a significant impact on the overall health of the body. In recent years, attention has been paid to potential relationships between periodontitis and various hematological disorders. This publication aims to present information available in the literature on this relationship, focusing on examples of red blood cell disorders (such as aplastic anemia and sickle cell anemia) and white blood cell disorders (such as cyclic neutropenia, maladaptive trained immunity, clonal hematopoiesis, leukemia, and multiple myeloma). Understanding these asso

… Aplastic Anemia (AA) Aplastic anemia is a rare disease defined as pancytopenia with bone marrow hypocellularity without abnormal infiltrates and without increased reticulocyte concentration. Most cases are acquired and have an immunological basis, but hereditary forms also occur. … The peripheral blood count shows decreased levels of HGB, erythrocytes, and HCT, with a simultaneously high level of reticulocytes, resulting from the marrow’s compensation for the destruction of sickled blood cells. …

Clinical and hematological evaluation of geriatric anemia.

BACKGROUND: Anemia in the elderly is a cause of concern. It is not merely physiological due to aging and requires appropriate evaluation. Anemia has a significant negative impact on cardiac function, cognition, sleep, frequent hospitalization, mobility, morbidity, and mortality. Anemia in the elderly is attributable to many causes: nutrient deficiencies, chronic inflammatory diseases, thyroid disorders, diabetes mellitus, gastrointestinal (GI) tumors and bleeding, chemotherapy-induced anemia, and drug-induced hemolysis. OBJECTIVES: We aimed to evaluate the clinical and hematological profile o

Actinium-225-PSMA-617 treatment in a patient with advanced prostate cancer causes secondary myelofibrosis: a case report and literature review.

Advanced prostate cancer (PCa) is still an incurable disease. Still, the field of PSMA-targeted radioligand therapy is developing rapidly and is playing an increasingly important role in the treatment of advanced Pca in the future. As an α -particle emitter, Ac-225 shows a potent killing ability for tumor cells due to its short range and high energy deposition in the tumor micrometastasis focus. However, the secondary myelofibrosis (SMF) associated with Ac-225-PSMA-617 treatment is a significant concern. We present a case of metastatic castration-resistant prostate cancer (mCRPC) who developed

Histiocytoid giant cellulitis-like Sweet syndrome at the site of sternal aspiration: A case report and review of literature.

BackgroundGiant cellulitis-like Sweet syndrome (SS) is a rare subtype of SS, and reports of the combined histiocytoid type of pathology are scarce. Here, we report a case of SS with distinctive clinical presentations and which was difficult to distinguish from cellulitis. By sharing this case and a discussion of the related literature in detail, we aim to provide clinicians with new insights into the characteristics of histiocytoid giant cellulitis-like (HGC)-SS and the pathogenesis of SS.Case summaryA 52-year-old male was admitted after experiencing progressive fatigue for 1 mo and tongue swe

Autoimmune Cytopenias Post Hematopoietic Stem Cell Transplantation in Pediatric Patients With Osteopetrosis and Other Nonmalignant Diseases.

Autoimmune cytopenia (AIC) is a rare complication post hematopoietic stem cell transplantation (HSCT), with a higher incidence in nonmalignant diseases. The etiology of post-HSCT AIC is poorly understood, and in many cases, the cytopenia is prolonged and refractory to treatment. Diagnosis of post-HSCT AIC may be challenging, and there is no consensus for a standard of care. In this retrospective study, we summarize our experience over the past five years with post-HSCT AIC in pediatric patients with osteopetrosis and other nonmalignant diseases. All pediatric patients who underwent HSCT for no

Экстренные ситуации в гематологии: Почему, когда и как я лечусь?

Гематологические чрезвычайные ситуации являются критическими медицинскими условиями, требующими неотложного внимания в силу их быстрого развития и опасного для жизни характера. В качестве примера можно привести гиперкальцемию, которая часто ассоциируется с раком, таким как множественная миелома, что может привести к серьезной неврологической и сердечной дисфункции. Гиперлейкоцитоз, распространенный в острой миэлоидной лейкемии, повышает риск лейкостаза и многоорганического отказа. Кислородный кризис, обычное осложнение серповидноклеточной болезни, является результатом вазооккуляции, приводящей

The Role of Extracellular Vesicles (EVs) in the Epigenetic Regulation of Bone Metabolism and Osteoporosis.

Extracellular vesicles (EVs) are complex phospholipidic structures actively released by cells. EVs are recognized as powerful means of intercellular communication since they contain many signaling molecules (including lipids, proteins, and nucleic acids). In parallel, changes in epigenetic processes can lead to changes in gene function and finally lead to disease onset and progression. Recent breakthroughs have revealed the complex roles of non-coding RNAs (microRNAs (miRNAs) and long non-coding RNAs (lncRNAs)) in epigenetic regulation. Moreover, a substantial body of evidence demonstrates tha

Clinical characteristics and outcome of tumor-associated acute pancreatitis: a single-center cohort study.

BACKGROUND: What features should alert clinicians to suspect underlying tumors in patients with acute pancreatitis (AP) was largely unknown. This study aimed to assess the clinical characteristics and outcome in patients with tumor-associated AP. METHODS: Patients who presented with AP and were diagnosed with tumor after admission were included according to the inclusion and exclusion criteria and followed up by hospital notes, telephone, WeChat and/or e-mail. The clinical characteristics and outcome were analyzed with multivariable logistic regression and were compared with AP patients witho

Recommendations of the SFH (French Society of Haematology) for the diagnosis, treatment and follow-up of hairy cell leukaemia.

Hairy cell leukaemia (HCL) is a rare haematological malignancy, with approximately 175 new incident cases in France. Diagnosis is based on a careful examination of the blood smear and immunophenotyping of the tumour cells, with a panel of four markers being used specifically to screen for hairy cells (CD11c, CD25, CD103 and CD123). In 2011, the V600E mutation of the BRAF gene in exon 15 was identified in HCL; being present in HCL, it is absent in the variant form of HCL (HCL-v) and in splenic red pulp lymphoma (SRPL), two entities related to HCL. The management of patients with HCL has changed

Endotoxaemia in haemodialysis: a novel factor in erythropoetin resistance?

Background/objectivesTranslocated endotoxin derived from intestinal bacteria is a driver of systemic inflammation and oxidative stress. Severe endotoxaemia is an underappreciated, but characteristic finding in haemodialysis (HD) patients, and appears to be driven by acute repetitive dialysis induced circulatory stress. Resistance to erythropoietin (EPO) has been identified as a predictor of mortality risk, and associated with inflammation and malnutrition. This study aims to explore the potential link between previously unrecognised endotoxaemia and EPO Resistance Index (ERI) in HD patients.Me

The potential therapeutic role of extracellular vesicles in critical-size bone defects: Spring of cell-free regenerative medicine is coming.

In recent years, the incidence of critical-size bone defects has significantly increased. Critical-size bone defects seriously affect patients' motor functions and quality of life and increase the need for additional clinical treatments. Bone tissue engineering (BTE) has made great progress in repairing critical-size bone defects. As one of the main components of bone tissue engineering, stem cell-based therapy is considered a potential effective strategy to regenerate bone tissues. However, there are some disadvantages including phenotypic changes, immune rejection, potential tumorigenicity,

T-Cell Lymphoma With Sarcoid-Like Reaction and Secondary Myelofibrosis: A Unique Case Report and Literature Review.

INTRODUCTION: T-cell lymphomas are rare, comprising 10%-15% of non-Hodgkin lymphomas (NHLs). Their etiology remains unclear, and pathophysiology varies widely among subtypes. Sarcoid-like reactions (SLRs) have been reported in approximately 7.3% of NHLs, including T-cell lymphomas, and can closely resemble sarcoidosis clinically/histologically. This overlap complicates diagnosis, particularly when secondary myelofibrosis-a rare and poorly understood complication-arises. Myelofibrosis has also been observed in sarcoidosis, further blurring the distinction between these entities. Treatment for T

The effect of oral nutrition supplement (ONS) on the nutritional and clinical status of patients undergoing autologous hematopoietic stem cell transplantation: study protocol for a randomized controlled clinical trial.

IntroductionSeveral side effects within the patients undergoing hematopoietic stem cell transplantation (HSCT), especially ones that influence nutrition intake, can cause weight loss and malnutrition. Based on studies, oral nutritional supplement (ONS) may reinforce their nutrient intake and progress clinical outcomes. The objective of this research is to investigate the effect of oral nutrition supplements on the nutritional and clinical status of patients undergoing autologous hematopoietic stem cell transplantation.MethodsAfter block randomization used the website www.randomization , 38 pat

SEOM clinical guidelines for anaemia treatment in cancer patients (2020).

Anaemia is defined by the presence of haemoglobin (Hb) levels < 13 g/dL in men and 12 g/dL in women. Up to 39% of cancer patients present it at the time of diagnosis and up to 40% have iron deficiency. Anaemia causes fatigue, functional deterioration and a reduction in the quality of life; it has also been associated with a poorer response to anti-tumour treatment and lower survival. Basic diagnostic tests for anaemia are simple and should be a routine part of clinical practice. These guidelines review the available evidence on the use of different therapies for treating anaemia: erythropoiesi

Experimental Drugs for Chemotherapy- and Cancer-Related Anemia.

Anemia in cancer patients is a relevant condition complicating the course of the neoplastic disease. Overall, we distinguish the anemia which arises under chemotherapy as pure adverse event of the toxic effects of the drugs used, and the anemia induced by the tumour-associated inflammation, oxidative stress, and systemic metabolic changes, which can be worsened by the concomitant anticancer treatments. This more properly cancer-related anemia depends on several overlapping mechanism, including impaired erythropoiesis and functional iron deficiency, which make its treatment more difficult. Stan

Unleashing the Impact of Exosomes Derived from Human Placental Mesenchymal Stem Cells (hPMSCs) on U-266 Myeloma Cell Line.

Multiple myeloma (MM) is a malignancy of plasma cells, terminally differentiated B cells, with complications like hypercalcemia, renal failure, anemia, and bone disease, which are also known as CRAB criteria. MM develops from monoclonal gammopathy of unknown significance (MGUS), a pre-malignant plasma cell dyscrasia. Over some time, MGUS has the potential to progress into smoldering multiple myeloma (SMM), which can evolve into MM. MM rarely progresses into plasma cell leukemia (PCL), a condition in which malignant plasma cells no longer stay in the bone marrow niche and circulate in the perip

Pathophysiology and Treatments of Complications of Waldenström's Macroglobulinemia.

Waldenstrom's macroglobulinemia (WM) or lymphoplasmacytic lymphoma is a B-cell malignancy characterized by lymphoplasmacytic cells in the bone marrow that secrete high amounts of immunoglobulin (Ig) M. The large pentameric structure of IgM leads to a variety of unique complications in WM, such as hyperviscosity syndrome, cryoglobulinemia and sensory neuropathy. Furthermore, malignant cells can infiltrate the central nervous system and lead to a variety of neurological complications, also known as Bing Neel Syndrome. Because of the unique pathophysiology of WM and these complications, their dia

Case report: Daratumumab treatment in pre-transplant alloimmunization and severe hemolytic anemia.

Daratumumab, a CD38 monoclonal antibody that has been FDA-approved to treat multiple myeloma, has acquired popularity and is used off-label for both auto- and alloantibody mediated disorders, particularly in refractory/resistant circumstances. Much of the published data for its use in pediatric blood disorders has been in post-transplant autoimmune cytopenias. Here we describe three patients in whom daratumumab was used outside of post-transplant autoimmune cytopenias, highlighting further potential uses of this medication.

Waldenström macroglobulinemia treatment algorithm 2018.

Waldenström macroglobulinemia is often an indolent disorder, and many patients are candidates for observation with careful monitoring. For symptomatic patients, one must distinguish between those patients whose symptoms are related to immunologic manifestations associated with the IgM monoclonal protein and those that have symptoms related to progressive marrow and nodal infiltration with lymphoplasmacytic lymphoma. In Waldenström macroglobulinemia, the driver for therapy in the majority of patients is progressive anemia, secondary to bone marrow replacement by lymphoplasmacytic lymphoma. Rece
