Background: Single donor apheresis platelets are superior in quality, but their usage is limited in a developing country due to cost and time constraints. Hence the product obtained must exceed in terms of yield, donor safety and technical convenience. Previous literature available on cell separators is on older versions.
Aims: Prospective comparison of 5 latest cell separators (AmiCORE, COM.TEC, Haemonetics MCS+, SpectraOptia and TrimaAccel) for product yield, performance variables and donor adverse effects.
Material & Methods: From October 2019 - March 2020, 1108 donors were randomly allotted to a cell separator. Post-donation sample was taken from the donor 15-20 minutes after procedure completion. The platelet yield from the product collected was measured twice (day 0 and day 1). Donor demography, pre-and post-procedural donor peripheral blood values, performance and product variables were statistically analyzed.
Results: AmiCORE had an optimal collection efficacy (44.6%) and collection rate (0.037 x 1011/minute). Haemonetics MCS+ had a better collection efficacy (48.4%) and rate (0.038 x 1011/minute). Spectra Optia achieved least procedural time (59.5 minutes), donor adverse effects (6.3%); highest collection efficacy (52.8%) and rate (0.056 x 1011/minute). Trima Accel achieved highest collection rate (0.056 x 1011/minute) and the least product volume (228 ml).
Conclusion: Highest collection efficacy was achieved by Trima Accel, highest collection rate by Trima Accel and Spectra Optia, lowest donor adverse effects by Spectra Optia and least number of procedural troubleshooting by COM.TEC. Apart from this, fiscal factors and service availability also need to be considered before choosing a cell separator.

Red cell exchange is important to treat acutely ill sickle cell patients, but it is time-consuming. An automated red cell exchange technique using cell separators developed by different manufacturers helps in removal of sickled hemoglobin and improving blood viscosity. The use of these cell separators permits automated red cell exchange to be performed safely and smoothly with the isovolemic hemodilution.

To support the evidence of plasma exchange's ability to rapidly lower serum TG levels and provide upcoming research opportunities for evaluating the long-term effects of this treatment, we present the case of a 35-year-old female who was admitted for Hypertriglyceridemia-induced Pancreatitis (HTGP). She underwent Therapeutic Plasma Exchange (TPE) using Spectra Optia Apheresis System on an emergency basis. The patient had a remarkable reduction of serum Triglycerides (TG) from 3953 to 291 mg/dl, which was life saving.

With the increasing prevalence of Crohn's disease (CD), treatment options for patients who fail conventional and advanced therapy are highly needed. Therefore, we explored the safety and efficacy of extracorporeal photopheresis (ECP) using 5-aminolevulinic acid (ALA) and blue light (405 nm). Patients with active CD who failed or were intolerant to biological therapy were eligible.

Unlabelled: : Extracorporeal photopheresis (ECP) is a well-established and efficacious cell therapy for a range of diseases. The objective of this retrospective study was to compare the new Amicus Blue inline system with the Therakos Cellex inline system and the Spectra Optia offline system in terms of collection efficiency, mononuclear cell (MNC) yield of mononuclear cell products (MCPs), processing time and correlation between MCP cell count and peripheral blood count of patients.
Methods: This retrospective study compared 127 procedures utilizing the Spectra Optia offline system, 93 procedures employing the Amicus Blue inline system, and 81 procedures applying the Therakos Cellex inline system.

Article Synopsis
- This review focuses on how sickle cell disease (SCD) affects patients' quality of life (QoL) and evaluates the effectiveness of automated red blood cell exchange (aRBCX) in improving QoL for these patients.
- Some studies show that aRBCX can improve health-related QoL by reducing hospital stays and pain-related admissions, while others find no significant changes, and it may lead to increased complications and complex vascular access.
- Although aRBCX shows promise in enhancing QoL for SCD patients, more in-depth studies with patient feedback are needed, and an approach that includes psychological support and pain management might further improve their QoL.*
