Pretreatment Immature Platelet Fraction as a Surrogate of Reticulated Platelets Predicts the Response to Corticosteroids in Adults with Immune Thrombocytopenia.

Objectives: Reticulated platelets circulating in the blood reflect megakaryopoietic activity and platelet turnover and can be automatically and low-invasively measured as the immature platelet fraction (IPF) using a Sysmex XN hematocytometer. The present study retrospectively investigated whether or not the IPF can predict the treatment response to corticosteroids in adult patients with primary immune thrombocytopenia (ITP).

Methods: Forty-six patients who had been newly diagnosed with primary treatment-naïve ITP and started treatment with corticosteroids were analyzed.

Potential role of Howell-Jolly bodies in identifying functional hyposplenism: a prospective single-institute study.

Although patients with cancer and immunosuppression are at a risk of functional hyposplenism, how to detect it promptly remains unclear. Since hyposplenism allows erythrocytes with nuclear remnants (Howell-Jolly bodies [HJBs]) to appear in the peripheral blood, HJB detection by a routine microscopic examination may help identify patients with functional hyposplenism. This prospective study was thus performed to determine the underlying diseases in patients who presented with HJBs.

Immunomodulatory and Metabolic Changes after Gnetin-C Supplementation in Humans.

Gnetin-C is a naturally occurring stilbene derived from the seeds of , an edible plant native to Southeast Asia that is called melinjo. Although the biological properties and safety of extract, which contains nearly 3% Gnetin-C, have been confirmed in various human studies, whether or not pure Gnetin-C is safe for humans is unclear at present. We conducted a randomized, double-blind, placebo-controlled trial.
