Context.—Assessing the amount of globotriaosylceramide inclusions in renal peritubular capillaries by a semiquantitative approach is a standard and useful measure of therapeutic efficacy in Fabry disease, achievable by light microscopy analysis. Objective.—To describe a novel virtual microscopy quantitative method to measure globotriaosylceramide inclusions (Barisoni Lipid Inclusion Scoring System [BLISS]) in renal biopsies from patients with Fabry disease. Design.—Plastic embedded 1-µm-thick sections from kidney biopsies from 17 patients enrolled in a Fabry disease clinical trial were evaluated using a standard semiquantitative methodology and BLISS to compare sensitivity. We also tested intrareader and interreader variability of BLISS and compared results from conventional light microscopy analysis with a virtual microscopy-based methodology. Peritubular capillaries were first annotated on digital images of whole slides by 1 pathologist and then scored for globotriaosylceramide inclusions by 2 additional pathologists. Results.—We demonstrated that (1) quantitative analysis by BLISS results in detection of small amount of globotriaosylceramide inclusions even when by semiquantitative analysis the score is 0, (2) application of BLISS combined with conventional light microscopy results in low intrareader and interreader variability, and (3) BLISS combined with virtual microscopy results in significant reduction of intrareader and interreader variability compared with BLISS–light microscopy. Conclusions.—BLISS is a simpler and more sensitive scoring system compared to the semiquantitative approach. The virtual microscopy–based methodology increases accuracy and reproducibility; moreover, it provides a permanent record of retrievable data with full transparency in clinical trials.

This paper describes the use of microcrystalline cellulose (MCC) as hydrophilic filler in two types of natural rubber latexes which are high ammonia natural rubber (HA) and epoxidised natural rubber latex (ENR). Light microscopy (LM), Scanning electron microscopy (SEM) and tensile strength measurements were then conducted on the resulting films. The light microscopy analysis revealed that more MCC particles appeared at the air–facing (AF) surfaces relative to the substrate-facing (SF) surfaces of the HA films with increasing MCC content. In contrary, the ENR25 films showed more or less similar MCC particles appearing at both air-facing surfaces and substrate-facing surfaces. Further SEM cryo-fracture analysis at the cross sections of the MCC filled ENR25 films indicated that the MCC particles were randomly dispersed in the rubber matrix. It can be suggested that the phase separation of MCC particles to the films surfaces occurred due to the incompatibility of MCC with the rubber matrix. Thus, it can be inferred that the occurrence of phase separation is minimised in the MCC filled ENR films in comparison to the MCC filled HA films.
