Adverse reactions associated with oral and parenteral use of cephalosporins: a retrospective population-based analysis.

Macy, Eric, Contreras, Richard·2015·Journal of Allergy and Clinical Immunology

Abstract

Background Few studies have provided population-based, route-specific data on allergy to cephalosporin or incidence of serious adverse drug reactions (ADRs).Objective We investigated the incidence of new reports of cephalosporin-associated "allergy" and serious ADRs.Methods We identified all members of the Kaiser Permanente Southern California health plan given cephalosporins (from January 1, 2010, through December 31, 2012), all new reports of cephalosporin-associated allergy, and all serious ADRs.Results There were 622,456 health plan members exposed to 901,908 courses of oral cephalosporins and 326,867 members exposed to 487,630 courses of parenteral cephalosporins over the 3-year study period. New reports of allergy to cephalosporin were more frequent among women (0.56%; 95% CI, 0.54% to 0.57%) than among men (0.43%; 95% CI, 0.41% to 0.44%) per course (P < .0001). The most frequent serious cephalosporin-associated ADRs were Clostridium difficile infection within 90 days (0.91%), nephropathy within 30 days (0.15%), and all-cause death within 1 day (0.10%). None correlated with history of drug allergy. Physician-documented cephalosporin-associated anaphylaxis occurred with 5 oral exposures (95% CI, 1/1,428,571-1/96,154) and 8 parenteral exposures (95% CI, 1/200,000-1/35,971) (P = .0761). There were 3 documented cephalosporin-associated serious cutaneous adverse reactions (95% CI, 0-1 in 217,291). All were associated with the use of another antibiotic at the same time as cephalosporin.Conclusions Cephalosporins are widely and safely used, even in individuals with a history of penicillin allergy. Physician-documented cephalosporin-associated anaphylaxis and serious cutaneous adverse reactions are rare compared with C difficile infection within 90 days, nephropathy within 30 days, and all-cause death within 1 day.

  • Anaphylaxis secondary to cephalosporins is extremely rare among persons who report a penicillin allergy and is estimated to occur at a rate of one per 52,000 persons.

    “Moreover, anaphylaxis secondary to cephalosporins is extremely rare among persons who report a penicillin allergy and is estimated to occur at a rate of one per 52,000 persons (652).”

  • Cross-reactivity between penicillin allergy and third-generation cephalosporins is low.

    “even though the cross-reactivity between penicillin allergy and third-generation cephalosporins is low (652–654).”

  • Data from the Kaiser health care system reported that among 3,313 patients with self-reported cephalosporin allergy who received a cephalosporin (mostly first generation), no cases of anaphylaxis were reported.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
