Systemic, asymptomatic skeletal muscle infiltration by MALT lymphoma: Defining a 'silent infiltrator' phenotype with 18F-FDG PET/CT.

We report a rare phenotype of Stage IV extranodal marginal zone lymphoma (MALT lymphoma) manifesting as diffuse, asymptomatic skeletal muscle and bone marrow infiltration in a 60-year-old female. Despite a high tumor burden and intense ¹⁸F-FDG avidity (SUVmax 8.8), muscle enzymes remained normal, indicating a non-destructive "silent infiltrator" growth pattern. The diagnosis was confirmed via biopsy (CD20+, CD5-, CyclinD1-) and negative MYD88 L265P mutation status, excluding lymphoplasmacytic lymphoma. The patient achieved a Complete Metabolic Response following Bendamustine-Rituximab therapy.

Acute ischaemia of the lower limb due to non-bacterial thrombotic endocarditis with recent venous thrombo-embolic disease as the initial manifestation of lung adenocarcinoma: a case report.

BackgroundNon-bacterial thrombotic endocarditis is a rare condition. Optimal management is based on early diagnosis which remains difficult.Case summaryA 75-year-old male patient was admitted to the hospital with acute ischaemia of the left lower limb due to popliteal artery occlusion despite anticoagulation with rivaroxaban for pulmonary embolism diagnosed 2 weeks earlier. Transoesophageal echocardiography (TOE) showed a mobile vegetation with mild mitral valve regurgitation. Positron emission tomography (PET) scan did not show hyperfixation at the mitral valve but rather lymphadenopathy hype

Cardiac Involvement in Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma.

Cardiac involvement of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is recognized extremely rarely. In addition, most CLL/SLL patients with heart infiltration are asymptomatic. In this review, we present the results of a literature search for English language articles concerning CLL/SLL or Richter transformation with symptomatic cardiac involvement. In total, 18 well-described cases with CLL/SLL and heart infiltration were identified. Only three patients were not diagnosed with CLL/SLL before the cardiac manifestation. In other patients, cardiac CLL/SLL was diagnosed betwe

Rituximab resistance in ITP and beyond.

The pathophysiology of immune thrombocytopenia (ITP) is complex and encompasses innate and adaptive immune responses, as well as megakaryocyte dysfunction. Rituximab is administered in relapsed cases and has the added benefit of inducing treatment-free remission in over 50% of patients. Nevertheless, the responses to this therapy are not long-lasting, and resistance development is frequent. B cells, T cells, and plasma cells play a role in developing resistance. To overcome this resistance, targeting these pathways through splenectomy and novel therapies that target FcγR pathway, FcRn, complem

Current Status of Gene Engineering Cell Therapeutics.

Ex vivo manipulations of autologous patient's cells or gene-engineered cell therapeutics have allowed the development of cell and gene therapy approaches to treat otherwise incurable diseases. These modalities of personalized medicine have already shown great promises including product commercialization for some rare diseases. The transfer of a chimeric antigen receptor or T cell receptor genes into autologous T cells has led to very promising outcomes for some cancers, and particularly for hematological malignancies. In addition, gene-engineered cell therapeutics are also being explored to in

Challenges in the Role of Gammaglobulin Replacement Therapy and Vaccination Strategies for Hematological Malignancy.

Patients with chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are prone to present with antibody production deficits associated with recurrent or severe bacterial infections that might benefit from human immunoglobulin (Ig) (IVIg/SCIg) replacement therapy. However, the original IVIg trial data were done before modern therapies were available, and the current indications do not take into account the shift in the immune situation of current treatment combinations and changes in the spectrum of infections. Besides, patients affected by other B cell malignancies present with similar i

Long-term outcomes of children after solid organ transplantation.

Solid organ transplantation has transformed the lives of many children and adults by providing treatment for patients with organ failure who would have otherwise succumbed to their disease. The first successful transplant in 1954 was a kidney transplant between identical twins, which circumvented the problem of rejection from MHC incompatibility. Further progress in solid organ transplantation was enabled by the discovery of immunosuppressive agents such as corticosteroids and azathioprine in the 1950s and ciclosporin in 1970. Today, solid organ transplantation is a conventional treatment with

Дело о том, что скрытая и литичная инфекция Эпштейна-Барра была направлена на множественный склероз.

Вирус Эпштейн-Барр (EBV) тесно связан с множественным склерозом (MS). Он, вероятно, сыграет причинно-следственную роль в патогенезе MS, возможно, путем инициирования автономного иммунитета с помощью молекулярной имитации, автоантигенного представления или регулирования иммунной дистрибьюции. С другой стороны, имеющиеся данные подтверждают прямую роль ЭБВ в стимулировании деятельности по болезням MS посредством скрытых литических инфекций в циклическом режиме либо в рамках ЦНС, либо на периферии. Мы обращаем особое внимание на недавние иммунологические и вирологические выводы, подтверждающие ро

Nutrition and Lifestyle-Related Factors as Predictors of Muscle Atrophy in Hematological Cancer Patients.

BACKGROUND: Cancer and side effects from cytostatic treatment commonly affect nutritional status manifested as a decrease in muscle mass. We aimed to investigate the impact of nutrition and lifestyle-related factors on muscle mass in patients with hematological cancer. METHODS: Dietary intake, food preferences, quality of life (QoL), and physical activity level (PAL) were monitored during 1-2 cytostatic treatment series. Body composition was estimated using bioelectrical impedance analysis (BIA). RESULTS: 61 patients were included. Weight loss and loss of muscle mass were detected in 64% and

Pathological fracture of primary lymphoma of bone: A case report on diagnosis and novel surgical management.

Primary lymphoma of bone (PLB) is an uncommon malignancy, representing ~4-5% of primary malignant bone tumors and 1% of all malignant lymphomas. Diffuse large B-cell lymphoma (DLBCL) is the most common subtype, accounting for ~80% of cases, and is highly curable with appropriate treatment. Therefore, accurate and timely diagnosis is crucial for favorable outcomes. The current study presents a 42-year-old male with primary DLBCL of the proximal humerus. The initial diagnosis was challenging due to overlapping morphological features with other small round cell tumors like Ewing's sarcoma and sma

A Rare Presentation of HIV-Negative Plasmablastic Lymphoma: A Diagnostic Dilemma.

Plasmablastic lymphoma (PBL) and plasmablastic plasma cell myeloma (PCM) have many overlapping characteristics. Clinical correlation can help make the distinction between the two entities. Human immunodeficiency virus- (HIV-) negative PBL is a rare disease, making the diagnosis more challenging. While there is no standard of care for PBL, current recommendations include dose-adjusted EPOCH (etoposide, vincristine, doxorubicin, cyclophosphamide, and prednisone), with or without bortezomib. We report an aggressive case of HIV-negative plasmablastic lymphoma and discuss the challenge in establish

Case Report: Management of Primary Tracheobronchial Light Chain Amyloidosis in a Patient With Biclonal Gammopathy Using a Systemic Bortezomib-Based Regimen.

Primary tracheobronchial light chain (AL) amyloidosis is a rare and heterogeneous disease characterized by the buildup of amyloid deposits in the airway mucosa. Although its treatment remains challenging, the current view is that the localized form can be treated conservatively due to its slow progression. While radiotherapy has proven effective in treating localized form of the disease, some patients do not respond to local treatment and continue to experience poor quality of life, highlighting the need to explore additional treatment strategies. In this report, we discuss a case of primary t

Incidence and risk factors for suicide and attempted suicide following a diagnosis of hematological malignancy.

Solid tumors are associated with an increased risk of suicide, however, there is limited detailed information on the risk of suicide in patients with hematological malignancies. Therefore, we conducted a population-based study including 47,220 patients with hematological malignancies (diagnosed 1992-2006) and their 235,868 matched controls to define the incidence and risk factors for suicide and suicide attempt. Information on suicides, suicide attempts, and preexisting psychiatric disorders was obtained from Swedish registers and individual medical records. There was a twofold increased (haza

Septic shock in the immunocompromised cancer patient: a narrative review.

Immunosuppressed patients, particularly those with cancer, represent a momentous and increasing portion of the population, especially as cancer incidence rises with population growth and aging. These patients are at a heightened risk of developing severe infections, including sepsis and septic shock, due to multiple immunologic defects such as neutropenia, lymphopenia, and T and B-cell impairment. The diverse and complex nature of these immunologic profiles, compounded by the concomitant use of immunosuppressive therapies (e.g., corticosteroids, cytotoxic drugs, and immunotherapy), superimpose

Serum Interleukin-6 is Not Linked with Sleep-Quality, Restless Legs Syndrome, and Depression, But with 6-Month Survival in Hematological Malignancies.

BackgroundSerum interleukin (IL)-6 has been found to be associated with sleep quality, mood, and survival in patients with solid tumors. Results in these studies were confounded by knowledge of diagnosis to study subjects. Moreover, such data among subjects with hematological malignancies and data regarding restless legs syndrome is limited. The present study was, therefore, conducted to assess the sleep quality, depression, and restless leg syndrome in hematological malignancies and to study if there is any role of IL6 associated with it.MethodsSixty-six subjects having hematological malignan

Oral and Maxillo-Facial Manifestations of Systemic Diseases: An Overview.

Many systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors pre

Paraneoplastic Neuropathies: What's New Since the 2004 Recommended Diagnostic Criteria.

The diagnostic criteria published by the PNS (Paraneoplastic Neurological Syndromes) Euronetwork in 2004 provided a useful classification of PNS, including paraneoplastic neuropathies. Subacute sensory neuronopathy (SSN) was the most frequently observed peripheral PNS, whereas other forms of neuropathy, as sensory polyneuropathy, sensorimotor polyneuropathy, demyelinating neuropathies, autonomic neuropathies, and focal nerve or plexus lesions, were less frequent. At the time of publication, the main focus was on onconeural antibodies, but knowledge regarding the mechanisms has since expanded.

Assessing the benefit: risk ratio of a drug--randomized and naturalistic evidence.

Randomized evidence from clinical trials and naturalistic evidence collected from pharmacoepidemiology and pharmacovigilance activities both contribute to the initial and continuous assessment of the benefits and risks of a drug, ie, the balance between therapeutic efficacy and safety risks. Benefit-risk assessment (BRA) mainly relies on a qualitative assessment of quantitative data. Current attempts to quantify BRA are reviewed and discussed, along with the expectations of regulatory authorities such as the Food and Drug Administration and the European Medicines Agency. No method provides a f
