Homoharringtonine (HHT) has been reported to induce hyperglycemia. This report describes a study conducted to characterize the effect of HHT on insulin production and action. Our data indicate that HHT-induced hyperglycemia results from the development of insulin resistance. A review of the literature suggests that patients receiving HHT continuous infusions of 5 mg/m2/d or greater and patients greater than 10 years of age may be at increased risk for the development of HHT-induced hyperglycemia. We recommend that patients with these risk factors, as well as diabetic patients and patients concurrently receiving asparaginase and/or prednisone, have their blood glucoses routinely monitored for hyperglycemia.
In support of the theory of a toxic genesis of mental diseases arising from chronic infection, some authors have attributed a special rôle to the B. coli. As long ago as 1904 Johnsohn and Goodall (1) examined the agglutination of a series of psychotics to the B. coli. They found this reaction completely or weakly positive in 50% of their cases of insanity (mostly with a serum dilution of 1: 100), while only 15.5% of their control cases showed a positive reaction. These results were not confirmed by Puca (2). Later on Goodall, together with Barton White (3), also examined the stool flora of psychotics, and found no qualitative difference as to the coliform group between psychotics and normal persons. On the other hand, Stewart (4), in more recent experiments, claims to have found such differences; thus he emphasizes the much higher frequency of the B. para-coli and B. coli mutabile in mental patients, especially in recent cases, and the parallelism between their presence and the intensity of the symptoms. Further, he found a difference in the phenol formation in broth cultures obtained from stools-of psychotics and normal persons, the former producing on the average 0.02 to 0.03%, and the latter only 0.008 to 0.03% of phenol. This stronger production of phenol is attributed by Stewart to the high frequency of B. Morgan and other phenol-producing bacteria in psychotics. He discusses the possibility that aromatic bodies produced by these bacteria in the acid milieu of the large intestine may represent the toxic agent in mental diseases.
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.
