Most active US LTx centers currently employ antifungal prophylaxis and treat Aspergillus colonization and IA, although choice of agent, route of administration, and duration of therapy across and within centers continue to differ substantially. The number of transplant dermatologists available among US LTx centers is limited. Overall, a strong need exists for more comprehensive consensus guidelines to direct antifungal prophylaxis and treatment of Aspergillus infection in LTx recipients.
Although there was no significant difference in SSI among patients prescribed prophylactic antibiotics, statistical precision was limited by the low incidence of infection. Larger population-based prospective registry studies including propensity adjustment are needed to confirm the benefit of prophylactic antibiotics in high-risk surgical cases.
Metabolic adverse effects such as hyperglycemia, alterations in insulin sensitivity, and weight gain are known to be potential complications of atypical antipsychotic therapy. In certain cases, hyperglycemia may be so profound that diabetic ketoacidosis (DKA) or hyperosmolar coma may result. Aripiprazole, approved by the United States Food and Drug Administration in 2002, appears to have fewer metabolic adverse effects than other atypical antipsychotics. We describe a 44-year-old man with no personal or family history of diabetes mellitus who was prescribed aripiprazole for schizoaffective disorder. Two weeks after starting this therapy, the patient developed DKA, which was corrected with insulin therapy and aggressive hydration. According to the Naranjo adverse drug reaction probability scale, aripiprazole was the probable trigger of his DKA. An exhaustive search for other causes of DKA was unrevealing. Administration of aripiprazole or any other atypical antipsychotic should be terminated when impaired glucose tolerance is suspected. Vigilance regarding the potential adverse effects of this class of drugs, including new agents such as aripiprazole, is crucial to preventing potentially life-threatening complications of hyperglycemia.
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.
