Severe diarrhea improved dramatically with administration of the humanized anti-interleukin-6 receptor antibody tocilizumab (TCZ) in a patient with secondary reactive amyloidosis, which was associated with rheumatoid arthritis (RA). A 53-year-old woman with RA went into hypovolemic shock because of severe watery diarrhea associated with gastrointestinal amyloidosis. The high-dose prednisolone therapy and glucocorticoid pulse therapy did not improve her intractable diarrhea. After TCZ administration, the life-threatening diarrhea lessened in about 6 h, and her vital signs became stable the next day. Perforation of the small intestine, however, occurred 2 days after TCZ administration. Whether TCZ could have been involved in the perforation in such a short time is unknown. Surgery was successful, and the patient recovered. TCZ may work immediately in diarrhea associated with secondary amyloidosis.
To minimize patient suffering, the smallest possible volume of blood should be collected for diagnosis and disease monitoring. When estimating insulin secretion capacity and resistance to insulin in diabetes mellitus (DM), increasing insulin assay immunosensitivity would reduce the blood sample volume required for testing. Here we present an ultrasensitive ELISA coupled with thio-NAD cycling to measure immunoreactive insulin in blood serum. Only 5 μL of serum was required for testing, with a limit of detection (LOD) for the assay of 10(-16) moles/assay. Additional recovery tests confirmed this method can detect insulin in sera. Comparisons between a commercially available immunoreactive insulin kit and our ultrasensitive ELISA using the same commercially available reference demonstrated good data correlation, providing further evidence of assay accuracy. Together, these results demonstrate our ultrasensitive ELISA could be a powerful tool in the diagnosis and treatment of not only DM but also many other diseases in the future.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
