Abstract
Cardiac aging involves the development of left ventricular hypertrophy alongside a decline in functional capacity. Here, we use neutral blood exchange to demonstrate that the acute removal of age-accumulated blood factors significantly regresses cardiac hypertrophy in aged mice. The reversal of hypertrophy was not attributed to age-associated hemodynamic effects, implicating a role of blood-derived factors. In addition, the overarching paradigm of systemic aging maintains that the age-related overabundance of plasma proteins are largely responsible for causing pathological phenotypes in tissues. Our results suggest that blood metabolites, not proteins, drive cardiac hypertrophy instead. Upon analyzing serum metabolomics data sets, we identified ophthalmic acid as a circulating metabolite whose levels increase with advanced age. Treatment of adult mouse and neonatal rat cardiomyocytes in culture with ophthalmic acid increased their relative surface areas. This study uncovers a non-protein metabolite that may contribute to cardiomyocyte hypertrophy during aging. Identifying a method to counteract ophthalmic acid's hypertrophic effects may reveal novel therapeutic opportunities for cardiac rejuvenation.

Abstract
Many pregnant women experience sleep disorders, and amino acid levels could play a crucial role in affecting maternal sleep. To explore this potential relationship, an accurate and effective UHPLC-MS/MS method has been developed to monitor 18 amino acids in the plasma samples of pregnant women. This method aims to assess how plasma amino acid levels might be linked to sleep disorders during pregnancy. Plasma samples were precipitated with acetonitrile containing 0.2% formic acid. We used 5% seralbumin as the surrogate matrix to establish quantitative curves for amino acid determination in human plasma. The method was validated in both the surrogate matrix and human plasma. The optimized UHPLC-MS/MS method was validated, showing that that the analytes had comparable recovery and negligible matrix effects in both 5% seralbumin and human plasma. The linearity, lower limit of quantification, precision, accuracy, and stability all met the acceptance criteria. The validated method was successfully applied to determination of the plasma levels of 18 amino acids in pregnant women with or without sleep disorders, indicating that alanine, lysine, tryptophan, glutamic acid, and phenylalanine levels had significant changes which may be related to sleep disorders during early pregnancy. An accurate, reliable, and efficient UHPLC-MS/MS method was successfully developed and support to find the specific amino acids as potential biomarkers for sleep disorders in pregnant women.

Therapeutic plasma exchange decreases serum triglyceride level rapidly and reduces early recurrence rate but no advantages in improving outcomes for patients with hyperlipidemic acute pancreatitis: a retrospective propensity score matching analysis based on twenty year's experience. BMC Endocr Disord 2024; 24:32. [PMID: 38443883 PMCID: PMC10916013 DOI: 10.1186/s12902-024-01562-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 02/23/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND Hyperlipidaemic acute pancreatitis (HLAP) has become the most common cause of acute pancreatitis (AP) not due to gallstones or alcohol (Mosztbacher et al, Pancreatology 20:608-616, 2020; Yin et al, Pancreas 46:504-509, 2017). Therapeutic plasma exchange (TPE) has been reported to be effective in reducing serum TG levels which is important in management of HLAP (World J Clin Cases 9:5794-803, 2021). However, studies on TPE are mostly focusing on cases reports, TPE remains poorly evaluated till date and need to be compared with conservative therapy with a well-designed study. METHODS A retrospectively cohort study on HLAP patients between January 2003 and July 2023 was conducted. Factors correlated with efficacy of TPE were included in a propensity model to balance the confounding factors and minimize selection bias. Patients with and without TPE were matched 1:2 based on the propensity score to generate the compared groups. Lipid profiles were detected on admission and consecutive 7 days. The triglyceride (TG) level decline rates, percentage of patients to reach the target TG levels, early recurrence rate, local complications and mortality were compared between groups. RESULTS A total of 504 HLAP patients were identified. Since TPE was scarcely performed on patients with TG < 11.3 mmol/L, 152 patients with TG level 5.65 to 11.3 mmol/L were excluded while 352 with TG ≧11.3 mmol/L were enrolled. After excluding 25 cases with incomplete data or pregnancy, 327 patients, of whom 109 treated without TPE while 218 treated with TPE, were included in data analysis. One-to-two propensity-score matching generated 78 pairs, 194 patients with well-balanced baseline characteristics. Of 194 patients enrolled after matching done, 78 were treated without while 116 with TPE. In the matched cohort (n = 194), patients treated with TPE had a higher TG decline rate in 48 h than those without TPE (70.00% vs 54.00%, P = 0.001); the early recurrence rates were 8.96% vs 1.83%, p = 0.055. If only SAP patients were analyzed, the early recurrence rates were 14.81% vs 0.00% (p = 0.026) respectively. For patients with CT severity index (CTSI) rechecked within 14 days, early CTSI improment rate were 40.90% vs 31.91%. Local complications checked 6 months after discharge were 44.12% vs 38.30%. Mortality was 1.28% vs 1.72%. No differences were found in early stage CTSI improment rate (P = .589), local complications (P = .451) or motality between two groups. CONCLUSIONS TPE reduces TG levels more quickly in 48 h compared with those with conservative treatment, but no difference in the consecutive days. TPE tends to reduce the early recurrence rate comparing with conventional therapy, but TPE has no advantages in improving CTSI in early stage, and no improvement for outcomes including local complications and mortalty.

Abstract
INTRODUCTION Simple plasma exchange (PE) with fresh-frozen plasma replacement allows antibody removal for ABO-incompatible living donor kidney transplantation, but is associated with a high incidence of allergic reactions. We developed, implemented, and evaluated a protocol for safe preoperative PE. METHODS The protocol comprised pretreatment (125 mg methylprednisolone infusion, 400 mg acetaminophen and 30 mg diphenhydramine orally) with a replacement fluid rate < 20 mL/min. Allergic reaction incidence was investigated in controls who underwent ABO-incompatible living donor kidney transplantation between 2016 and March 2020 (group C) and patients who underwent the protocol and procedure between April 2020 and February 2023 (group N). RESULTS Ten (group C) and 19 (group N) patients performed 11 and 30 sessions of PE, respectively. Allergic reactions occurred in 81.8% and 36.7% (p = 0.014), respectively, with an odds ratio of the protocol was 0.056 (95% CI 0.0059-0.5380, P = 0.013). CONCLUSION Our protocol resulted in a significantly lower incidence of allergic reactions.

Abstract
Intravenous immune globulin (IVIG) is a common treatment given after plasma exchange procedures to either prevent secondary hypogammaglobulinemia or as an adjunctive treatment for organ transplant rejection. However, side-effects are relatively common with this medication during and after infusion. This case-report describes our alternative to IVIG infusions post-plasma exchange. We hypothesize that in patients unable to tolerate IVIG, using thawed plasma as a replacement fluid provides a suitable increase in the patients post procedure immunoglobulin G (IgG) levels for patients with secondary hypogammaglobulinemia that are unable to tolerate IVIG infusions.

Abstract
BACKGROUND In the Alzheimer Management by Albumin Replacement (AMBAR) study, mild-to-moderate Alzheimer's disease (AD) patients were treated with a plasma exchange (PE) program. Feasibility and safety of PE in this specific population are poorly understood and were analyzed in detail in this study. METHODS Qualified patients were treated with 6 weeks of weekly conventional therapeutic plasma exchange (TPE) with albumin replacement followed by monthly low-volume plasma exchange (LVPE) for 12 months. The patients were divided into four groups: placebo (sham PE treatment), low-albumin (20 g), low-albumin + intravenous immunoglobulin (IVIG) (10 g), and high-albumin (40 g) + IVIG (20 g). Adverse events (AEs) were recorded and analyzed for all PE treatment groups and PE modalities. RESULTS PE procedure-related AEs were more common in the active treatment groups (16.9% out of 1283 TPE and 12.5% out of 2203 LVPE were associated with at least one AE, a similar rate than in other PE indications) than in the placebo group (0.7% out of 1223 sham PE). Percentage of procedures with at least one AEs was higher with central venous access compared to peripheral venous access in all three active treatment groups (20.1% vs 13.1%, respectively). CONCLUSION The TPE and LVPE procedures used in the AMBAR study on mild-to-moderate AD population were as safe and feasible as in other therapeutic applications of PE or routine plasmapheresis.

Abstract
Background The number of end-stage renal disease (ESRD) patients is increasing in Bangladesh. Currently, living kidney donation is the only viable option for transplantation in Bangladesh, and it is further restricted by ABO compatibility issues. We have performed ABO-incompatible kidney transplantations (ABOi KTs) in Bangladesh since 2018. This study examines our experiences with seven cases of ABOi KT. Methods The desensitization protocol included low-dose rituximab (100 mg/body) followed by plasma exchange (PEX), which was followed by a 5-g dose of intravenous immunoglobulin. Immunosuppression was undertaken using tacrolimus (0.1 mg/kg/day), mycophenolate mofetil (1,500 mg/day), and prednisolone (0.5 mg/kg/day). All patients received basiliximab for induction therapy. Results The median baseline anti-ABO antibody titer was 164 (range, 132–1128). Transplantation was performed at a titer of ≤18. Our patients attended three to five PEX sessions before transplantation. Graft survival was 100% in the seven cases over a mean period of 22 months. The mean creatinine level was 204.6±47.4 µmol/L. Two patients were suspected of having developed acute rejection and received intravenous methylprednisolone, resulting in improved kidney function. One patient required posttransplant hemodialysis due to delayed graft function and subsequently improved. Infection was the most common complication experienced by ABOi KT patients. Two patients developed severe cytomegalovirus pneumonia and died with functioning grafts. Conclusions ABOi KT in Bangladesh will substantially expand the living kidney donor pool and bring hope to a large number of ESRD patients without ABO-compatible donors. However, the high cost and risk of acute rejection and infection remain major concerns.

Abstract
Therapeutic plasma exchange is used as a trial method for the treatment of cancer patients. Therapeutic plasma exchange uses in vitro technology to remove pathogenic factors in the plasma, returning the replacement and remaining components to the patient to facilitate cure. In the effort to explore new methods of cancer treatment, the introduction of therapeutic plasma exchange brings new hope for cancer treatment; however, the current evidence supporting therapeutic plasma exchange is controversial, and most of the evidence comes from observational studies, lacking large prospective randomized trials. Therefore, this review attempts to focus on the main indications of therapeutic plasma exchange for the treatment of tumors and their complications, including hematological tumors (multiple myeloma cast nephropathy and hyperviscosity syndrome), nervous system tumors (myasthenia gravis associated with thymoma, paraneoplastic neurological syndrome, Lambert–Eaton myasthenia syndrome, and anti-N-methyl-D-aspartate receptor encephalitis), overdose of chemotherapy drugs. In addition, the issues of side-effects and safety in the use of therapeutic plasma exchange are also discussed. However, well-designed prospective trials are needed to better define the role of therapeutic plasma exchange in cancer.

Abstract
Extracorporeal therapy is a treatment modality where human blood undergoes favorable technical modifications and is reintroduced into the same patient. Since the last four decades this technique has been deployed in the management of difficult and refractory disorders in dermatology. Over a period of time newer techniques like immunoadsorption has emerged and opened new vistas in management of morbid dermatoses. In extracorporeal photopheresis a patient's leukocytes are separated and treated outside with Ultra Violet A in presence of 8-methoxypsoralen. Double filtration plasmapheresis and Immunoadsorption are techniques to remove offending immune complexes. They are safe and reduce the need of toxic medications that are conventionally used in recalcitrant skin diseases. In recent years immunoadsorption is emerging as first-line therapy in condition like immunobullous diseases. High cost is one of the important factors limiting their wider use in developing countries like India. Our review discusses different extracorporeal therapies, their applications, recommendations and guidelines based on various clinical trials.

Abstract
Aging is associated with the impairment of stem cell activation, leading to the functional decline of tissues and increasing the risk for age-associated diseases. The old, damaged or unrepaired tissues disturb distant tissue homeostasis by secreting factors into the circulation, which may not only serve as biomarkers for specific age-associated pathologies but also induce a variety of degenerative phenotypes. In this review, we summarize and discuss systemic determinants that perpetuate age-related tissue dysfunction. We further elaborate on the effects of attenuating these circulating factors by highlighting recent advances which utilize plasmapheresis in a pre-clinical or clinical setting. Overall, we postulate that repositioning therapeutic plasma exchange (TPE) to dilute the systemic factors, which become deleterious at their age-elevated levels, could be a rapidly effective rejuvenation therapy that recalibrates crucial signaling pathways to a youthful state.

Abstract
Therapeutic plasma exchange (PLEX) involves the removal of detrimental substances, commonly pathogenic antibodies or toxins, from a patient's blood by exchanging their plasma with a replacement fluid. While a variety of replacement fluids are available, human albumin (4-5 %) is the most commonly used, as it is widely available, easily stored, and generally well tolerated. Despite its excellent safety profile, adverse reactions to albumin are well documented, ranging in severity from mild allergic symptoms to severe anaphylaxis. This report describes two cases of patients receiving frequent PLEX who developed sensitivities to human albumin. These patients differed substantially in the manifestations of their symptoms, the duration of their treatment, and their medical indication for PLEX. In both cases, symptom onset occurred shortly after completion of plasma exchange procedures and lasted for several hours. Symptoms disappeared when the patients were switched to albumin from a different manufacturer, suggesting that the reaction was specific to that formulation of albumin and not to the albumin itself. These cases highlight the possibility of manufacturer-specific acquired albumin sensitivities and provide a simple framework for the initial approach to the management of such reactions.

Abstract
Antimicrobial treatment during therapeutic plasma exchange (TPE) remains a complex issue. Recommendations based on a limited number of experimental studies should be implemented in clinical practice with caution. Effective management of infections due to plasma or albumin-related interactions, as well as impaired pharmacokinetics, in critical illness is difficult. Knowing the pharmacokinetics of the drugs concerned and the procedural aspects of plasmapheresis should be helpful in planning personalized treatment. In general, possessing a low distribution volume, a high protein-binding affinity, a low endogenous clearance rate, and long distribution and elimination half-lives make a drug more prone to elimination during TPE. A high frequency and longer duration of the procedure may also contribute to altering a drug's concentration. The safest choice would be to start and finish TPE before antimicrobial agent infusion. If this not feasible, a reasonable alternative is to avoid administering the drug just before TPE and to delay the procedure for the time of the administered drug's distributive phase. Ultimately, if plasma exchange must be performed urgently or the drug has a very narrow therapeutic index, monitoring its plasma concentration is advised.

Exp Ther Med 2020; 19:2427-2432. [PMID: 32256719 PMCID: PMC7086183 DOI: 10.3892/etm.2020.8501] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Accepted: 09/10/2019] [Indexed: 02/07/2023] Open
Abstract
The aim of the present study was to investigate the effects of various triglyceride (TG)-lowering therapies on hypertriglyceridemia-induced acute pancreatitis (HTGAP). A total of 132 patients with HTGAP were retrospectively divided into an insulin intensive therapy (IIT), a plasma exchange (PE) and a non-intensive insulin therapy (NIIT) group according to the TG-lowering therapies they had received. The clinical and biochemical data of the subjects were analyzed. The baseline data, including sex, age, TG, amylase, severe acute pancreatitis and systemic inflammatory response syndrome were not significantly different among the three groups (P>0.05). The 24-h TG clearance rate (χ2=7.74, P=0.021), onset to treatment time (χ2=14.50, P<0.001) and the time required to reach the target TG level (χ2=6.12, P=0.047) were different in these three groups, but no significant differences were observed between the IIT and NIIT groups (P>0.05). The incidence of therapy-associated complications in the PE group (30.23%) was higher than that in the IIT (2.17%) and NIIT (4.65%) groups. The difference in the incidence of therapy-associated complications was significant among the three groups (P<0.001), but no significant difference was present between the IIT and NIIT groups (P>0.05). In the PE group, the length of stay was increased compared with that in the IIT and NIIT groups (χ2=7.05, P<0.05), while there was no significant difference between the IIT and NIIT groups (P>0.05). The present study suggested that NIIT at presentation had a similar therapeutic efficacy to that of IIT to improve the prognosis of HTGAP, and NIIT and IIT were associated with fewer complications than PE treatment. NIIT may favorably perform in patients presenting early after symptom onset and may be considered for clinical application.

Abstract
Background/aim High triglyceride (TG) levels are associated with increases in atherosclerotic cardiovascular disease (CVD), hepatic steatosis, and pancreatitis. Acute pancreatitis is a condition with high mortality. Therapeutic plasma exchange (TPE) in the treatment of hypertriglyceridemic pancreatitis (HTGP) is a rapid and effective treatment modality. In this study, the results of TPE were evaluated and the frequency of lipoprotein lipase (LPL) mutation in these patients was determined. Materials and methods TPE was performed in 31 patients with HTGP at the Adult Therapeutic Apheresis Center. Results A TG level under 500 mg/dL was achieved by applying apheresis at a median of 2 times (IQR 2–2, min 1, max 6) in the 31 cases. LPL mutation was detected in 8 (25.8%) of the 31 hypertriglyceridemia cases. When TG levels before and after TPE were evaluated, the mean TG level before TPE was significantly higher (3132 ± 1472 mg/dL) than the mean TG level afterwards (948 ± 465 mg/dL, P < 0.001). This result represented a decrease of 69.7% TG after TPE. Conclusion TPE is a safe, fast, and effective treatment modality in experienced centers.

Abstract
In recent years, the incidence of hyperlipidemic acute pancreatitis has increased year by year. At present, the exact pathogenesis is still unclear. It may be related to the increase of free fatty acids due to increased triglyceride (TG), which leads to toxicity to the pancreas, pancreatic microcirculation disorder, and calcium overload. The key to treatment is to reduce TG rapidly. Lifestyle changes and weight loss are the key to preventing recurrence.

Abstract
For decades, kidney diseases related to inappropriate complement activity, such as atypical hemolytic uremic syndrome and C3 glomerulopathy (a subtype of membranoproliferative glomerulonephritis), have mostly been complicated by worsened prognoses and rapid progression to end-stage renal failure. Alternative complement pathway dysregulation, whether congenital or acquired, is well-recognized as the main driver of the disease process in these patients. The list of triggers include: surgery, infection, immunologic factors, pregnancy and medications. The advent of complement activation blockade, however, revolutionized the clinical course and outcome of these diseases, rendering transplantation a viable option for patients who were previously considered as non-transplantable cases. Several less-costly therapeutic lines and likely better efficacy and safety profiles are currently underway. In view of the challenging nature of diagnosing these diseases and the long-term cost implications, a multidisciplinary approach including the nephrologist, renal pathologist and the genetic laboratory is required to help improve overall care of these patients and draw the optimum therapeutic plan.

Abstract
PURPOSE For the treatment of thyrotoxicosis, alternative treatment modalities may be necessary if anti-thyroid drugs cannot be used due to side effects, inefficiencies, or there is a need to start a rapid action such as thyroid storm. By using therapeutic plasma exchange (TPE), it is possible to effectively and rapidly remove the increased thyroid hormones. We evaluated our results and experience on a rapid, effective, and reliable alternative treatment modality in thyrotoxic patients. METHODS TPE was performed in 46 thyrotoxic patients at the Adult Therapeutic Apheresis Center. RESULTS Forty six patients with a median age of 30 years (interquartile range [IQR] 30-50) were assessed. In 40 (87%) of the cases, the diagnosis was Graves' disease. The other causes of thyrotoxicosis were amiodarone-induced thyrotoxicosis (n = 4) and toxic nodular goiter (n = 2). The median and IQR of fT3 values in patients before TPE were 9.9 (6.5-16.8) pg/mL (N: 2.3-4.2) and the median and IQR of fT4 values were 2.9 (2.3-4.1) ng/dL (N: 0.74-1.52). When the procedure was terminated, the median and IQR of fT3 values in patients were 4.0 (3.1-5.2) pg/mL and the median and IQR fT4 values were 1.6 (1.4-2.0) ng/dL. The decrease in both free thyroid hormones was found to be statistically significant (p < 0.000). CONCLUSION Our study is the largest series of TPE in the literature used for thyrotoxicosis. In the light of the literature and our results, we conclude that TPE is an effective alternative treatment option to prepare for ablative treatment for cases that have side effects or ineffectiveness of anti-thyroid drugs.

Abstract
About 30% of the cases of steroid resistant nephrotic syndrome display a genetically determined disease and will not recur after kidney transplant; the other cases with fully or partially immunological pathogenesis display a high risk of post transplant recurrence. Although lots of studies were carried out in the last 50 years the pathogenetic mechanism is still obscure and the therapeutic approach mostly empirical. The cornerstones principles of the therapies are based on removal of a still undefined "permeability factor" through plasma-exchange or other apheresis techniques and inhibition of its synthesis by the immunological system through different drugs. The probability of successfully inducing persistant remission is nowadays around 30%through the different schemes experimented so far which mostly include plasmapheresis. Rituximab in the last years has significantly increased the efficacy of the treatments. Non responders are rapidly evolving to graft loss and will most probably recur also in subsequent transplant. Apart from genetics no other risk factors are predictive for recurrence.

Abstract
BACKGROUND AND AIMS Circulating levels of von Willebrand factor (vWF) predict mortality in patients with cirrhosis. We hypothesized that systemic inflammation in acute-on-chronic liver failure (ACLF) will stimulate endothelium, increase vWF levels, and promote platelet microthrombi causing organ failure. METHODS In this prospective study, we correlated plasma vWF levels with organ failure, liver disease severity, sepsis, and systemic inflammatory response syndrome (SIRS) and also analyzed if vWF levels predicted in-hospital composite poor outcome (i.e. death/discharged in terminal condition/liver transplantation) in consecutive ACLF patients. RESULTS Twenty-one of the 50 ACLF patients studied had composite poor outcome. ACLF patients had markedly elevated vWF antigen and activity (sevenfold and fivefold median increase, respectively) on days 1 and 3. Median ratio of vWF to a disintegrin and metalloprotease with thrombospondin type 1 motif, member 13 (ADAMTS13) activity on day 1 was significantly higher in ACLF patients (11.2) compared to 20 compensated cirrhosis patients (3.3) and healthy volunteers (0.9). On day 1, area under ROC curve (AUROC) to predict composite poor outcome of hospital stay for ACLF patients for vWF antigen, vWF activity, and model for end-stage liver disease (MELD) score were 0.63, 0.68, and 0.74, respectively. vWF activity correlated better with liver disease severity (MELD score, ACLF grade) and organ failure (Sequential Organ Failure Assessment [SOFA] score) than vWF antigen; in contrast, neither vWF antigen nor activity correlated with platelet count, sepsis, or SIRS. CONCLUSIONS vWF levels are markedly elevated, correlate with organ failure, and predict in-hospital survival in ACLF patients. This data provides a mechanistic basis for postulating that vWF-reducing treatments such as plasma exchange may benefit ACLF patients.

Abstract
BACKGROUND Patients presenting with acute episodes of thrombotic microangiopathies (TMAs) require urgent access to plasma exchange (PEX). OctaplasLG, a solvent/detergent fresh-frozen plasma product that has undergone viral inactivation and prion reduction step, has been used in our institution since 2013, replacing Octaplas. STUDY DESIGN AND METHODS We prospectively reviewed 981 PEX procedures where OctaplasLG was the replacement fluid in 90 patients admitted acutely with a TMA presentation within our institution from January 1, 2013, to December 31, 2015. We recorded citrate toxicities, plasma reactions, viral transfer, complications related to central venous catheter, and venous thrombotic events (VTEs). RESULTS Citrate toxicities were 5.4%, plasma reactions were 2%, and all were classified as Grade 1 or 2. VTE had an incidence of 12.2%, although 50% of the episodes occurred in early remission when patients were not receiving PEX. No line insertions complications were recorded. Line-associated infections were 2.2%. Hepatitis B and C serology and human immunodeficiency virus (HIV) were checked on admission. There were four patients who may have had passive transient transfer of hepatitis B antibodies from pooled plasma. No hepatitis C or HIV viral transfer was documented after treatment and no seroconversion was detected after treatment. CONCLUSION Our data have demonstrated that the incidence of complications during PEX is low and using OctaplasLG is comparable to the low incidence of reactions. No cases of anaphylaxis, transfusion-related acute lung injury, or fatal plasma reactions were seen. There was no evidence of viral transmission or seroconversion after treatment.

Abstract
Human serum albumin (HSA) is a non-glycosylated, negatively charged protein (Mw: about 65-kDa) that has one free cystein residue (Cys 34), and 17 disulfide bridges that these bridges have main role in its stability and longer biological life-time (15 to 19 days). As HSA is a multifunctional protein, it can also bind to other molecules and ions in addition to its role in maintaining colloidal osmotic pressure (COP) in various diseases. In critical illnesses changes in the level of albumin between the intravascular and extravascular compartments and the decrease in its serum concentration need to be compensated using exogenous albumin; but as the size of HSA is an important parameter in retention within the circulation, therefore increasing its molecular size and hydrodynamic radius of HSA by covalent attachment of poly ethylene glycol (PEG), that is known as PEGylation, provides HSA as a superior volume expander that not only can prevent the interstitial edema but also can reduce the infusion frequency. This review focuses on various PEGylation methods of HSA (solid phase and liquid phase), and compares various methods to purifiy and characterize the pegylated form.

Abstract
OBJECTIVES Acute hypertriglyceridemia induced pancreatitis (HTP) presents with a more severe clinical course compared to other etiologies of pancreatitis. Therapeutic plasma exchange (TPE) is a potential treatment option for lowering plasma triglycerides and possibly decreasing morbidity and mortality. However, clinical data regarding its effectiveness are limited. METHODS We retrospectively examined the clinical data and outcomes of 13 consecutive episodes of HTP in which TPE was employed to reduce plasma triglycerides during a 15-month period. RESULTS The TPE was initiated at a median of 19 hours from the time of presentation. We performed 1.2-1.5 volume TPEs with 5% albumin as the replacement fluid. After only one TPE procedure, the mean plasma triglycerides values decreased from 2993 mg/dl to 487 mg/dl with a reduction of 84%. All 13 patients survived with a mean length of hospital stay of 9.5 days. There were no complications related to TPE. CONCLUSIONS One TPE procedure is an effective method for reducing plasma triglycerides and possibly decreases the length of hospital stay in patients admitted with HTP.

Abstract
Apheresis is a collective term for several activities in which a desirable specific blood component is separated and collected or a harmful component is removed. During the last decades the application of apheresis has expanded to a broad spectrum of diseases due to various studies on the clinical efficacy of this therapy as well as the innovation of new techniques. However, adverse events quite often occur during apheresis. In this article we will give a brief overview on general principles, indications and complications of apheresis.

Abstract
Therapeutic plasmapheresis has been used for intractable diseases that cannot be cured by conventional drug therapy. Currently, the use of therapeutic plasmapheresis has been approved for 27 diseases by Japan's National Health Insurance system and is mainly categorized into three modalities: plasma exchange (PE), double-filtration plasmapheresis (DFPP), and plasma adsorption (PA). Plasma separators and/or fractionators are essential for the therapy. PE is performed for two purposes: removal of pathogenic antigens or substances in the plasma fraction and supplementation of essential factors, such as albumin and coagulation factors. PE can be used for thrombotic microangiopathy and acute hepatic failure. DFPP can be performed for selective removal of macromolecules while avoiding the use of substitution fluid (i.e., albumin or fresh frozen plasma). DFPP has now been used for conditions involving relatively larger plasma molecules, including hyperviscosity syndrome and ABO-incompatible kidney transplantation. PA can specifically remove pathogenic agents, such as low-density lipoprotein or autoantibodies, in the IgG fractions by the adsorption column and does not require substitution fluids. PA has now been used for a wide variety of neurological diseases, including chronic inflammatory demyelinating polyneuropathy. This review describes the characteristics of each modality, seeking to improve the efficacy and specificity of removal of the target substance.

Abstract
Abstract
Plasma exchange is a therapeutic procedure used to treat a variety of diseases through the bulk removal of plasma. To apply this treatment to patients appropriately, it is essential to understand the methods to remove plasma, its effects on normal plasma constituents, the role of replacement fluids in the treatment, and the risks associated with the procedure. To facilitate the appropriate evidence-based use of plasma exchange and to encourage research, the American Society for Apheresis has published guidelines providing practical guidance and information to those responsible for ordering or providing this treatment.

Abstract
Albumin is one of the oldest known and studied human proteins. It is characterised by diverse physiological and biochemical properties that render it relevant to many aspects of the disordered vascular and cellular functions after trauma. Apart from the ability to maintain the colloid oncotic pressure, human serum albumin has multiple effects, including antioxidant activity and binding affinity for drugs and toxic substances, inhibition of apoptosis and modulation of trauma-induced inflammatory response. According to the current state of knowledge, there are conflicting results regarding the benefits of albumin administration in critically ill patients. Further investigations are warranted to resolve the continued uncertainty about the safety and efficacy of human serum albumin in specific clinical circumstances and selected populations of severely injured patients.
