Data collection on the apheresis activity in Italy throughout 1997 was performed by means of a standardized questionnaire. These data, provided by 96 Apheresis Units from 13 Italian regions, albeit rough, are sufficiently informative. In 1997, a total number of 170,373 apheresis sessions was carried out, with a clear-cut prevalence of productive apheresis (92%) that was performed by all Apheresis Units. Lombardy, Venetia and Latium were the most active regions for therapeutic apheresis (56% of total activity).

Background: Although revascularization is first-line therapy for chronic limb-threatening ischemia (CLTI), there are no established treatments for patients in whom revascularization is not (or is a poor) option, including CLTI that has responded poorly to revascularization. This study verified the efficacy of the Rheocarna, a novel apheresis device, for no-option CLTI or poor-response CLTI after revascularization.
Methods And Results: This multicenter retrospective observational study analyzed 221 patients (221 limbs) with no- or poor-option CLTI (mean [±SD] age 71±10 years; males, 70.
Objectives The optimal dosing schedule strategy for granulocyte colony-stimulating factor (G-CSF) in healthy stem cell donors remains controversial. This study aimed to compare the efficacy of once-daily versus twice-daily G-CSF administration in allogeneic stem cell donors. Materials and methods We retrospectively analyzed data from 388 healthy unrelated donors (282 males, 106 females) who underwent stem cell mobilization at our center between September 2018 and June 2022.

Background: Cold agglutinin disease (CAD) or syndrome (CAS) can be particularly challenging when autologous stem cell transplant (ASCT) is needed. Standard peripheral blood stem cell (PBSC) collection and manipulation involve ex vivo blood manipulations at lower than body temperature, predisposing to agglutination during graft collection, handling, processing, and infusion.
Study Design And Methods: We describe the first case of ASCT for relapsing lymphoma in a patient with high-titer CAD requiring anti-complement therapy and chronic transfusion.
Evaluation of ultrasonography and plethysmography in detecting blood loss and volume replacement in a platelet apheresis model.

Medical Faculty of Suleyman Demirel University, Blood Transfusion Center, Turkey.
Background: Rapid, reproducible, and noninvasive diagnostic methods like Ultrasonography (US) and plethysmographic measurements such as the perfusion index (PI) and pleth variablity index (PVI) have great potential value for emergency trauma cases in which blood loss needs to be recognized quickly and accurately.
Objectives: We planned this study to evaluate the utility of US, PI, and PVI in detecting early-stage hemorrhage and mimicking volume replacement using a platelet apheresis model.
Methods: This prospective, observational study included 46 healthy platelet apheresis volunteers who met inclusion criteria.
Complement-Mediated Hemolytic Uremic Syndrome Due to MCP/CD46 Mutation: A Case Report.

Marshall University, Huntington, WV, USA.
Thrombotic microangiopathy (TMA) is a severe condition characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage, often involving the kidneys. Complement-mediated hemolytic uremic syndrome (cHUS), a rare form of TMA, arises from dysregulated alternative complement pathway activation, frequently due to genetic mutations. We report the case of a 23-year-old male presenting with TMA secondary to a heterozygous mutation in the membrane cofactor protein (MCP/CD46) gene.
