Evidence for the treatment of calciphylaxis with pharmacotherapeutic interventions is limited to case reports. Further research is necessary to fully describe the optimal use of sodium thiosulfate, bisphosphonates, and cinacalcet for the treatment of calciphylaxis, including their pharmacokinetics in adults with CKD, optimal dosing strategies, and duration of therapy.

Vancomycin-induced immediate hypersensitivity reactions include RMS and anaphylaxis. Vancomycin desensitization should be considered for severe RMS reactions not responding to usual measures and in anaphylactic reactions to vancomycin, when substitution of another antbiotic is not feasible.

The numerous drugs to which the acutely ill are exposed place these patients at a significant risk of developing drug-induced thrombocytopenia. Such patients tend to have preexisting hemostatic defects that place them at additional risk of complications as a result of the drug-induced thrombocytopenia. The clinical challenge is to provide rapid identification and removal of the offending agent before clinically significant bleeding or, in the case of heparin, thrombosis results. Drug-induced thrombocytopenic disorders can be classified into three mechanisms: bone marrow suppression, immune-mediated destruction, and platelet aggregation. Clinical characteristics, preliminary laboratory findings, and drug history specific to the mechanisms can assist clinicians in rapidly isolating the causative drug.

Based on antifactor Xa activity, ESRD has little effect on the pharmacokinetics of enoxaparin, and dosing adjustments are unnecessary.
