Some ribosomal antibiotics used in clinical practice to fight pathogenic bacteria can provoke serious adverse drug reactions in patients. Sensitivity to the antibiotics is a multifactorial trait but the genetic variation of sensitive individuals to off-target effects of the drugs might be one of the factors contributing to this condition. Thus, the protein synthesis apparatus of mitochondria is similar to that of bacteria because of its endosymbiotic origin and, therefore, mitochondrial ribosomes are frequently unintended off-targets of these antibiotics...

PURPOSE: The case of a patient with multiple medication hypersensitivity reactions and a methicillin-resistant Staphylococcus aureus (MRSA) infection who underwent desensitization to ceftaroline is reported. SUMMARY: A 32-year-old Caucasian woman with asthma, gastroesophageal reflux disease, heart murmur, and major depression was admitted for MRSA cellulitis with a subcutaneous abscess along the left sternomanubrial joint and clavicular osteomyelitis secondary to port placement after gastric bypass surgery...

OBJECTIVE: To review the evidence for the use of steroids in adults presenting with Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), or overlap. DATA SOURCES: EMBASE (1974 to April 2014), MEDLINE (1946 to April 2014), Cochrane Database of Systematic Reviews, and International Pharmaceutical Abstracts (1970 to January 2014) were searched using the terms: prednisone, methylprednisolone, dexamethasone, prednisolone, steroids, glucocorticoids, corticosteroids, Stevens-Johnson Syndrome, toxic epidermal necrolysis, and SJS/TEN overlap...

BACKGROUND: Cross-reactivity between penicillins or cephalosporins and carbapenems is anticipated as all have a beta lactam ring. However, the true incidence of immunoglobulin (Ig)E-mediated cross-reactivity is not known. METHODS: A systematic review was conducted to collect and combine all published data on children and adults reported to have a clinical history of IgE-mediated hypersensitivity to a penicillin and/or cephalosporin who were subsequently given a carbapenem...

Among patients with a reported history of penicillin allergy, 80% to 90% have no evidence of IgE antibodies to penicillin on skin testing and thus avoid penicillin unnecessarily. Moreover, 97% to 99% of such patients with a penicillin skin test negative to the major and minor determinants can tolerate penicillin without risk of an immediate-type hypersensitivity reaction. A penicillin skin test is valuable for evaluating penicillin allergy in patients who need penicillin or cephalosporin. Assessment of sensitivities to penicillin is important to reduce the unnecessary use of antimicrobial agents such as vancomycin...
