Bendamustine and rituximab as frontline therapy in extranodal marginal zone lymphoma: a single-institution experience.

Extranodal marginal zone lymphoma (EMZL) encompasses 70% of cases of marginal zone lymphoma. Frontline bendamustine and rituximab (BR) were derived from trials involving other indolent non-Hodgkin's lymphomas. Only one trial has evaluated frontline BR prospectively in EMZL.

Impact of Anti-PEG IgM Induced via the Topical Application of a Cosmetic Product Containing PEG Derivatives on the Antitumor Effects of PEGylated Liposomal Antitumor Drug Formulations in Mice.

Poly(ethylene glycol) (PEG) is used in many common products, such as cosmetics. PEG, however, is also used to covalently conjugate drug molecules, proteins, or nanocarriers, which is termed PEGylation, to serve as a shield against the natural immune system of the human body. Repeated administration of some PEGylated products, however, is known to induce anti-PEG antibodies.

Treatment-induced and Pre-existing Anti-peg Antibodies: Prevalence, Clinical Implications, and Future Perspectives.

Polyethylene glycol (PEG) is a versatile polymer that is used in numerous pharmaceutical applications like the food industry, a wide range of disinfectants, cosmetics, and many commonly used household products. PEGylation is the term used to describe the covalent attachment of PEG molecules to nanocarriers, proteins and peptides, and it is used to prolong the circulation half-life of the PEGylated products. Consequently, PEGylation improves the efficacy of PEGylated therapeutics.

Brentuximab vedotin plus AVD for Hodgkin lymphoma: incidence and management of peripheral neuropathy in a multisite cohort.

Brentuximab vedotin (BV) in combination with doxorubicin, vinblastine, and dacarbazine (AVD) is increasingly used for frontline treatment of stage III/IV classical Hodgkin lymphoma (cHL). Peripheral neuropathy (PN) was the most common and treatment-limiting side effect seen in clinical trials but has not been studied in a nontrial setting, in which clinicians may have different strategies for managing it. We conducted a multisite retrospective study to characterize PN in patients who received BV + AVD for newly diagnosed cHL.

Toxicity of a Modified PEG-Asparaginase-Based SMILE Regimen Is Comparable to L-Asparaginase-Based SMILE in a Non-Asian Population.

Introduction: L-asparaginase-based chemotherapy regimens are effective for treating chemotherapy-resistant natural killer- (NK-) cell neoplasms. To treat these lymphoma subtypes in Asia, where NK/T-cell lymphomas are more prevalent, the NK-Cell Tumor Study Group developed the SMILE regimen, which includes a steroid, methotrexate, ifosfamide, L-asparaginase, and etoposide. In the US however, the only commercially available form of asparaginase is the pegylated form (PEG-asparaginase) which has been incorporated into a modified SMILE (mSMILE).

Outcomes of CD19-Targeted Chimeric Antigen Receptor T Cell Therapy for Patients with Reduced Renal Function Including Dialysis.

Patients with renal impairment (RI) are typically excluded from trials evaluating chimeric antigen receptor (CAR) T cell therapies. We evaluated the outcomes of patients with RI receiving standard of care (SOC) CAR T cell therapy for relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL). In this retrospective, single-center cohort study of patients with R/R DLBCL treated with SOC axicabtagene ciloleucel (axi-cel) or tisagenlecleucel (tisa-cel) after 2 or more prior lines of therapy, renal and survival outcomes were compared based on RI and fludarabine dose reduction (DR) status.

Pneumococcal Conjugate Vaccine Does Not Induce Humoral Response When Administrated Within the Six Months After CD19 CAR T-Cell Therapy.

CD19 targeted chimeric antigen receptor-modified T cell therapy (CAR-T) leads to B cell aplasia and low serum immunoglobulin levels. Long-lived CD19-negative plasma cells may persist through the therapy and generate antibodies. There is a paucity of data describing how CAR-T impacts the persistence of antibodies against vaccine-related antigens and the degree to which CAR-T recipients may respond to vaccines.

Spontaneous Spinal Subdural Hematoma Secondary to Hemophilia A and Zanubrutinib.

Spontaneous spinal subdural hematomas (SSH) are rare occurrences that can occur most commonly secondary to vascular malformations or coagulopathies. Only a small fraction of spontaneous SSHs are caused by acquired coagulation disorders such as leukemia, hemophilia, and thrombocytopenia. This case report describes a patient with a history of Guillain-Barré syndrome (GBS), hemophilia A, and mantle cell lymphoma, on zanubrutinib therapy, a Bruton tyrosine kinase inhibitor associated with a risk of spontaneous hemorrhage.

An international analysis evaluating frontline bendamustine with rituximab in extranodal marginal zone lymphoma.

Extranodal marginal zone lymphoma (EMZL) is a heterogeneous non-Hodgkin lymphoma. No consensus exists regarding the standard-of-care in patients with advanced-stage disease. Current recommendations are largely adapted from follicular lymphoma, for which bendamustine with rituximab (BR) is an established approach.

BTK Inhibitors in Chronic Lymphocytic Leukemia.

Purpose Of Review: The treatment landscape of chronic lymphocytic leukemia (CLL) has dramatically changed over the last few years with the introduction of novel targeted agents. Physicians are now faced with several equally effective therapy options when treating patients with CLL. Here, we review the role of Bruton tyrosine kinase (BTK) inhibitors in treating patients with treatment-naïve and relapsed or refractory CLL.

Phase I/II study of bendamustine in combination with ofatumumab, carboplatin, etoposide (BOCE) for relapsed or refractory aggressive B-cell non-Hodgkin lymphoma.

We developed an outpatient salvage chemotherapy regimen using bendamustine, ofatumumab, carboplatin and etoposide (BOCE) to treat relapsed/refractory non-Hodgkin lymphoma (RR NHL) in a single-center phase I/II study. Primary objectives were safety, tolerability and overall response rate (ORR). Thirty-five RR NHL patients (57% de novo large cell [DLBCL] or grade 3B follicular [FL], 26% transformed DLBCL, 9% grade 3A FL, 3% mantle cell; median age = 62, median prior therapies = 1) were treated.

Hodgkin lymphoma arising in patients with chronic lymphocytic leukemia: outcomes from a large multi-center collaboration.

Chronic lymphocytic leukemia (CLL) patients who develop Hodgkin lymphoma (HL) have limited survival. No current therapeutic standard of care exists. We conducted a multi-center retrospective study of patients with Hodgkin Transformation (HT) of CLL.

Serratia marcescens Tricuspid Valve Vegetation and Successful Use of the AngioVac® System.

bacteremia is common in patient populations with a history of intravenous drug use (IVDU), but it rarely causes infective endocarditis. We are reporting a 27-year-old female with a medical history significant for IVDU and hepatitis C virus infection who presented to the emergency department complaining of fever and shortness of breath. Computed tomography of the chest with intravenous (IV) contrast revealed extensive bilateral pulmonary infiltrates with multiple cavitary lesions.

Preparation and Evaluation of Cubosomes/Cubosomal Gels for Ocular Delivery of Beclomethasone Dipropionate for Management of Uveitis.

Purpose: Topical corticosteroids administration is commonly used for management of various ocular conditions especially those affecting the anterior segment of the eye. Poor solubility and limited pre-corneal residence time result in insufficient drug penetration to the outer (cornea and conjunctival-scleral) coats of the eye. This study aimed to prepare and evaluate cubosomes for prolonging residence time and enhancing ocular bioavailability of BDP.

Impending Cardiac Tamponade as the Initial Manifestation of BCR-ABL Positive Chronic Myeloid Leukemia.

Leukemia involves all organs and tissues of the body. Leukemic infiltration of the pericardium has been documented frequently at post-mortem examinations. Clinically, however, pericardial effusion with cardiac tamponade is rare, and only isolated case reports have been described.

Corticosteroids in ophthalmology: drug delivery innovations, pharmacology, clinical applications, and future perspectives.

Corticosteroids remain the mainstay of the treatment for various ocular conditions affecting the ocular surface, anterior and posterior segments of the eye due to their anti-inflammatory, anti-oedematous, and anti-neovascularization properties. Prednisolone, prednisolone acetate, dexamethasone, triamcinolone acetonide, fluocinolone acetonide, and loteprednol etabonate are amongst the most widely used ophthalmic corticosteroids. Corticosteroids differ in their activity and potency in the eye due to their inherent pharmacological and pharmaceutical differences.

A Rare Case of Subacute Painful Thyroiditis Causing Thyroid Storm and a Successful Trial of Propylthiouracil.

Thyroid storm is a rare, life-threatening condition characterized by severe or exaggerated clinical manifestations of thyrotoxicosis, commonly occurring in patients with longstanding, untreated hyperthyroidism such as Graves' disease and toxic nodular goiter. Subacute painful thyroiditis, also known as de Quervain thyroiditis, is a self-limited inflammatory disease of the thyroid gland that is characterized by neck pain, a tender diffuse thyroid goiter, elevated inflammatory markers, and a predictable course of thyroid function evolution. Rarely, it can cause thyroid storm.

A Rare Case of Serratia marcescens Causing Mycotic Aneurysm and Septic Emboli in Intravenous Drug User.

There are few literatures highlighting the presence of a mycotic aneurysm in the setting of bloodstream infection by Serratia. A 33-year-old male with a history of Marfan syndrome, mitral valve prolapse, and intravenous drug use (IVDU) presented to the ED with fever, nausea, and non-bloody emesis, and vague abdominal pain with concern for sepsis. With the strong association between IVDU and infective endocarditis, transthoracic and transesophageal echocardiograms were performed and were negative for vegetations.

Acute Unilateral Oculomotor Nerve Palsy as the Initial Presenting Sign of Nonfunctioning Apoplectic Gonadotroph Adenoma.

Pituitary macroadenoma usually presents with visual field defects. Oculomotor nerve palsy is a rare presentation, and usually a sign of para-sellar growth and cavernous sinus extension. The oculomotor nerve is more susceptible to laterally transmitted pressure by pituitary mass expansion because of its anatomical location.

COVID-19 Fears May Be Worse Than the Virus: A Case of Cardiogenic Shock Secondary to Post-Myocardial Infarction Ventricular Septum Rupture.

Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, there has been a growing and justifiable fear of catching the virus from the emergency rooms, thus decreasing the hospital visits. With Virginia State slowly reopening and HCA local hospitals resuming elective procedures, the number of emergency room visits, are recovering and increasing. We report a sad and unfortunate case of an 87-year-old female who was experiencing pressure-like chest pain but presented to the emergency room five days later out of fear of catching COVID-19 from the hospital.
