INTRODUCTION: Lipoprotein X (Lp-X) is an abnormal lipoprotein found in multiple disease conditions, including liver dysfunction and cholestasis. High Lp-X concentrations can interfere with some laboratory testing that may result in spurious results. The detection of Lp-X can be challenging, and there is currently a lack of consensus regarding the management of Lp-X other than treating the underlying disease. CASE PRESENTATION: A 42-year-old female with Hodgkin's lymphoma treated with dexamethasone, high dose cytarabine and cisplatin and vanishing bile duct syndrome confirmed by liver biopsy presented with cholestasis, pseudohyponatremia (sodium, 113 mmol/L; reference range 136-146 mmL/L; serum osmolality, 303 mOsm/kg), and hypercholesterolemia (> 2800 mg/dL, reference range < 200 mg/dL)...

BACKGROUND AND AIMS: Primary sclerosing cholangitis has a poor prognosis and can be accompanied by ulcerative colitis. Infection control is essential, so immunosuppressive drugs should ideally be preferably. Granulocyte and monocyte adsorptive apheresis does not suppress the immune system and is used to treat ulcerative colitis. Therefore, this study investigated the efficacy and safety of granulocyte and monocyte adsorptive apheresis in patients with primary sclerosing cholangitis and ulcerative colitis...

BACKGROUND: Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic inflammation of the gastrointestinal tract, affecting millions of individuals throughout the world, and producing an impaired health-related quality of life. Granulocyte and monocyte apheresis (GMA) is a therapeutic option for UC management to induce remission by selective removal of activated leukocytes from bloodstream. Despite the knowledge of the important role of epigenetics in UC pathogenesis, and in the response to different treatments, nothing is known about the role of microRNAs in GMA therapy in UC patients...

Chronic lymphocytic leukemia (CLL) is a clonal mature B-cell neoplasm with a typically indolent clinical course. Though most clinicians follow these neoplasms through observation alone, an aggressive transformation to prolymphocytic leukemia, diffuse large-B-cell lymphoma (Richter transformation) or classical Hodgkin lymphoma requires immediate attention. We present a case of extreme leukocytosis (>1 million/μL) in a previously diagnosed CLL patient. Due to symptomatic leukostasis, she was started on cytoreductive therapies including leukocytapheresis...

Guillain-Barré syndrome (GBS) is an immune-mediated polyradiculoneuropathy and the most common cause of acute flaccid paralysis worldwide. GBS classically presents with acute, progressive, ascending weakness, reduced to absent reflexes, and albuminocytological dissociation on cerebrospinal fluid (CSF) analysis. Botulism is a neurotoxin-mediated acute descending flaccid paralysis with cranial nerve palsies and dysautonomia. Botulism in adults is caused by ingestion/inhalation of botulinum toxin or wound infection with Clostridium botulinum...

INTRODUCTION: Peripheral blood stem cell (PBSC) harvesting requires reliable and safe vascular access. In our institution, a change of practice was implemented and the central venous catheter (CVC) placement for all autologous PBSC collections was abandoned in favor of a careful evaluation of peripheral venous access (PVA) for each individual patient. The aim of this prospective study was to evaluate the rate of patients with adequate peripheral veins for autologous PBSC collection and compare patient characteristics, collection efficacy, and complication rate between patients with PVA and CVC...

Understanding the apheresis principles for harvesting hematopoietic stem cells (HSCs) is critical for performing efficient procedures. However, despite significant advances in estimating the collection efficiency (CE) of aphereses, many confounding factors still need to be addressed in the classical calculations. The CE values are unrestricted, and many procedures exhibit CEs of a given cell population greater than 100%. This report introduces a simple equation that estimates the "crude" CE, which ranges from 0% to 100% and intrinsically considers the contribution of donor-related variables such as the pre-procedure mobilization and intra-apheresis recruitment of CD34+ cells (as a convenient marker for HSCs), as well as the performance of the apheresis system itself...

We present three cases of severely elevated plasma free hemoglobin (PFH) in pediatric patients on mechanical circulatory support devices at a tertiary pediatric care center. Due to severe levels of PFH in the setting of critical illness with the inability to pursue immediate mechanical device exchange, membrane filtration therapeutic plasma exchange (TPE) was performed, which resulted in a lowering of PFH levels. However, long-term outcomes were heterogeneous across the cases. This case series reviews patient presentation, organ function before and after TPE, and the overall role of TPE as an effective treatment option to decrease severely elevated PFH levels...

Therapeutic plasma exchange (TPE) is an effective treatment for several renal disorders, including renal transplant rejection. However, repeated plasma exchanges can result in various metabolic disturbances and complications. We present a 61-year old male with a medical history of type 2 diabetes, hypertension, successfully treated multiple myeloma, and a post-mortem kidney transplantation 7 months prior to presentation. The patient was hospitalized with an antibody-mediated transplant rejection for which treatment with methylprednisolone, TPE with a 40 g/L albumin solution as a replacement fluid, and intravenous immunoglobulins was initiated...

Adsorptive cytapheresis proves effective in a proportion of patients affected by ulcerative colitis. Relatively high cost and the need for apheresis facilities, prevented the widespread use of this therapeutic approach. More so following the introduction of anti-TNFα biosimilars which proved both effective and inexpensive. Anti-TNFα agents, however, are burdened by high rate of primary and secondary non-response and prompt switching to new, high-cost biologics, and small molecules. The present review analyzes advantages and disadvantages of adsorptive cytapheresis in the present clinical scenario and suggests its repositioning in the therapeutic workup of selected subgroups of ulcerative colitis patients...

BACKGROUND: Therapeutic plasma exchange (TPE) removes both pathologic and protective immunoglobulins (Ig). SARS-CoV-2 immunity is partially mediated by anti-SARS-CoV-2 spike antibodies (SAb), which impair viral host-cell invasion. Nonetheless, the systematic effect of TPE on SAb concentration and SARS-CoV-2 immunity is unknown. METHODS: Paired plasma waste specimens from the first (first-TPE) and last (last-TPE) TPE treatment were collected from 9 patients between July 21, 2021 and March 1, 2022...
