BACKGROUND: Therapeutic plasma exchange (TPE) is an extracorporeal procedure which consists of removing the patient's plasma and replacing it with an appropriate replacement fluid. Plasma and blood cells are separated by a centrifugation process. Our department has used TPE for several years, and in 2013 we introduced an institutional apheresis protocol. The main objective of this report is to describe the TPE procedures performed between 2013 and 2016 in the Peruvian population. METHODS: We analyzed the technical and clinical aspects of 864 centrifugal TPE procedures as well as the associated complications...

Thrombotic microangiopathies (TMAs) are rare, but life-threatening disorders characterized by microangiopathic hemolytic anemia and thrombocytopenia (MAHAT) associated with multiorgan dysfunction as a result of microvascular thrombosis and tissue ischemia. The differentiation of the etiology is of utmost importance as the pathophysiological basis will dictate the choice of appropriate treatment. We retrospectively evaluated 154 (99 females and 55 males) patients who received therapeutic plasma exchange (TPE) due to a presumptive diagnosis of TMA, who had serum ADAMTS13 activity/anti-ADAMTS13 antibody analysis at the time of hospital admission...

The use of therapeutic plasma exchange in the pediatric age group is mostly based on retrospective, single-center experiences. The decision to implement apheresis in pediatric patients is usually adopted from the results of studies on adult patients. In order to expand the limited data on pediatric TPE in general and non-hematooncological disorders in particular, we retrospectively evaluated TPE experience in pediatric patients who underwent the procedure for reasons other than hematooncological disorders. A total of 160 sessions in 34 patients (21 females and 13 males) with a median age of 7 (1-17) were analyzed...

Several neurological disorders have been described in patients with autoimmunity associated with GAD antibodies. Among these disorders, nystagmus and oculomotor dysfunction are increasingly recognized, although they have been rarely reported isolated or as the main manifestation of anti-GAD autoimmunity. Moreover, therapeutic approaches for such patients are unclear. Here we present a 44-year-old man with disabling oscillopsia secondary to downbeat nystagmus, abnormal saccades, ocular pursuit and optokinetic nystagmus, as well as mild gait ataxia and cerebellar atrophy associated with high serum GAD antibodies with intrathecal secretion of such antibodies...

Patients with clinically amyopathic dermatomyositis (CADM), a subset of dermatomyositis characterized by a lack of muscle involvement, frequently develop rapidly progressive and treatment-resistant interstitial lung disease. We report the case of a 49-year-old man who was diagnosed with CADM. He developed interstitial pneumonia, which did not respond to combination therapy with methylprednisolone pulse therapy, cyclophosphamide, and cyclosporine. We therefore attempted plasma exchange. After 7 courses of therapeutic plasma exchange, the interstitial pneumonia gradually improved...

Endothelial cells (ECs) are located at the interface between flowing blood and the vessel wall, and abnormal EC proliferation induced by pathologic environments plays an important role in vascular remodeling in hypertensive conditions. Exchanges of information between blood components and ECs are important for EC function. Hence, the present study sought to determine how platelets induce EC dysfunction under hypertensive conditions. EC proliferation was increased in renal hypertensive rats established by abdominal aortic coarctation compared with control rats and that elevated thrombin in plasma promoted platelet activation, which may induce the release of platelet-derived microparticles (PMPs)...

Catastrophic thrombotic syndrome is characterized by occurrence of several thromboembolic occlusions which affect a variety of vascular beds over a short period of time. Catastrophic Antiphospholipid syndrome (CAPS) (1%) is regarded as a rare but severe variant of Antiphospholipid Syndrome. Treatment with anticoagulants, steroids and therapeutic plasma exchange has been shown to give the best results. However, to treat CAPS, the best substitute for plasma is still a debatable issue because there are no standard methods...

Hyperviscosity syndrome (HVS) is most commonly associated with Waldenstrom's macroglobulinemia, where it may be life-threatening. HVS may also occur in autoimmune diseases; data pertaining to efficacy of therapeutic plasma exchange (TPE) in HVS arising in non-malignant gammopathy are limited. We report a case of 71-year-old female with erosive rheumatoid arthritis with profoundly elevated rheumatoid factor (57,400 IU/ml; normal <35) who presented with findings consistent with HVS: profound weakness, headache, epistaxis and plasma viscosity (8...

BACKGROUND: Rapidly progressive glomerulonephritis (RPGN) is characterized by a rapid deterioration of renal function and by extracapillary proliferation in >50% of glomeruli. The most common type of RPGN is "pauci-immune" glomerulonephritis caused by anti-neutrophil cytoplasmic antibodies-associated vasculitis (AAV). SUMMARY: The incidence of AAV increases with age and pauci-immune glomerulonephritis is the most common diagnosis found in renal biopsies in the elderly population...

BACKGROUND: Therapeutic hypothermia is neuroprotective in asphyxiated neonates by counteracting mechanisms contributing to brain injury. Although an initial increased permeability is part of an inflammatory reaction and thereby a natural healing process, an excessive endothelial permeability with edema formation may result in impaired hemodynamics. Reduced permeability may, however, benefit healing. Although plasma and interstitial colloid osmotic pressure are accessible and essential parameters for understanding fluid imbalance, the mechanisms of fluid exchange remain poorly understood...

Therapeutic plasma exchange is an apheresis modality in which plasma is separated from the blood cellular components ex vivo, discarded, and replaced with an isosmotic fluid (most commonly 5% albumin) to maintain appropriate oncotic pressure in the patient. Therapeutic plasma exchange is used in the treatment of many diseases and indications. The recent seventh edition of the American Society for Apheresis guidelines indicates approximately 72 diseases and 116 indications for which therapeutic plasma exchange may be effective...

Tunneled central venous catheters with ports are increasingly used for therapeutic apheresis procedures. Vortex ports have been used as access for therapeutic apheresis procedures, but are not ideal for therapeutic plasma exchange (TPE) procedures due to lower flow rates. We performed an in vitro experiment to compare flow characteristics of the single-lumen Vortex port (AngioDynamics) with the single-lumen TidalPort (Norfolk Medical). We used expired red blood cell units and adjusted the hematocrit to 40% with normal saline in a 2-L bag...

Therapeutic plasma exchange (TPE) on severely ill neonates poses many technical challenges, including obtaining adequate vascular access. In addition, clinical challenges such as risk of hypotension and cardiovascular instability are more pronounced in these patients. We report an approach to successfully managing these challenges while performing TPE on a 4 kilogram neonate using the Spectra Optia and 22 G venous access.

A 67-year-old right-handed woman presented with dysarthria, left upper extremity weakness and right-sided neglect of 3 hours duration. Imaging of the brain revealed acute right middle cerebral artery stroke; however, tissue plasminogen activator could not be administered due to severe thrombocytopenia. A peripheral smear revealed schistocytes and the patient was treated empirically for thrombotic thrombocytopenic purpura (TTP) with therapeutic plasma exchange. An extensive workup revealed no embolic source or other cause for stroke, and a diagnosis of large vessel infarct secondary to TTP was made...

Cryoglobulins are produced by the over-stimulated immune system of patients with hepatitis C virus (HCV). HCV-induced cryoglobulinemic vasculitis primarily affects small-sized vessels of systemic organs. The most common symptoms are purpura, joint pain, and peripheral neuropathy or Raynaud phenomenon. The blood tests of patients with HCV may exhibit raised erythrocyte sedimentation rate and C-reactive protein levels, positive rheumatoid factor and cryoglobulins, and decreased complement levels. Therapeutic options for HCV-induced cryoglobulinemic vasculitis, include anti-virals, Rituximab, steroids, immunosuppressant drugs, and plasma exchange...
