Ciprofloxacin, Piperacillin/tazobactam (pip/tazo) (used alone or in combinations not including cefuroxime) and none (no antimicrobials) compared to people receiving cefuroxime (used alone or in combinations non including the antibiotic in question). Smith ME, Reid DM, Jones CE, Jordan JV, Kautz CA, SHULMAN NR. Hansen, C. Wamberg, T.D. Ampicillin was developed to overcome the issue of drug resistance and extend the antimicrobial coverage of penicillins. There is also evidence that within GPIX there exists a site that is favored not only by quinine but also by rifampicin- and ranitidine-induced antibodies [25;26]. The epitopes recognized by antibodies from patients with quinine- and sulfonamide-induced thrombocytopenia have been characterized for selected target molecules. Immune-mediated thrombocytopenia secondary to suramin. Table 2. A site involving the "hybrid" and PSI homology domains of GPIIIa (beta 3-integrin subunit) is a common target for antibodies associated with quinine-induced immune thrombocytopenia. Immune-mediated platelet consumption is associated with a large number of drugs leading to drug-induced immunologic thrombocytopenia (DITP) in which platelet destruction is caused by immunoglobulins that recognize specific platelet membrane glycoproteins (GPs) only in the presence of the sensitizing drug noncovalently associated with a specific GP. Jensen, B. Lundgren, J. Grarup, M.L. Clausen, R. Winkel, J. Huusom, D.L. We report, using a randomized trial, the potential of antimicrobials to induce thrombocytopenia. Abstract Drug-induced immune hemolytic anemia (DIIHA) is rare, and a specialized laboratory is often required to provide the optimal serological tests to confirm the diagnosis. Finally, the existence of a drug-specific antibody has been recently reported that directly recognizes quinine itself in a subset of patients experiencing quinine-induced immune thrombocytopenia [47]. Antibody binding to the platelets is the causative mechanism. Kiefel V. The MAIPA assay and its applications in immunohaematology. Takahashi K, Kropshofer H, Vogt AB, Gleichmann E, Griem P.

Helps you get and maintain an erection when you need it. As discussed above, several factors may be associated with the probability of using certain antimicrobials which may introduce bias due to confounding. Unasyn has active ingredients of ampicillin sodium; sulbactam sodium. the contents by NLM or the National Institutes of Health. The combination of ampicillin and sulbactam is available in a parenteral form generically and previously under the name Unasyn. It was hypothesized that antibodies causing DITP recognize circulating drug directly to form immune complexes somehow reacting with platelets as "innocent bystanders" to cause their destruction [21;70;71]. Carey PJ. Patients with absolute thrombocytopenia within the first few days after ICU admission had a 67% relative elevated risk of dying within the 28 day study period. We compared single antimicrobial use in separate models with the use of cefuroxime as the comparator group. Some dosage forms listed on this page may not apply to the brand name Unasyn. Moreover, pseudothrombocytopenia, an artifactual clumping of platelets in vitro without clinical significance, should also be ruled out [36]. ELISA and IP-WB allow assessing both the presence and specificity of DDAbs. Hundreds of drugs have been implicated in the pathogenesis of DIT. Use NS for IV piggyback. Antimicrobials are often given in combinations related to type of infection. Careers, Unable to load your collection due to an error. Factors that should be considered for the failure to demonstrate DDAbs include poor solubility in an aqueous medium of some drugs; the possibility that the sensitizing agent can be a structurally modified form of the sensitizing drug resulting from in vivo metabolism [44;8385]; and a possible requirement that autologous cells be used for testing [86]. Plasma therapies in thrombotic syndromes. What is Unasyn? What is the best way to determine if thrombocytopenia in a patient on multiple medications is drug-induced? Demonstration of an immune-mediated mechanism of penicillin-induced neutropenia and thrombocytopenia. As noted, the ELISA techniques, while not as sensitive, facilitates identification of the target molecules with which DDAb react; these include the antigen capture ELISA assay, in which a monoclonal antibody specific for a platelet membrane glycoprotein is plated onto microtiter wells and used to capture the specific membrane glycoproteins from a platelet lysate (ACE, MAIPA) [80;82] and a modified antigen capture ELISA in which the drug-dependent antibodies are first incubated in the presence or absence of drug with intact platelets, the cells containing bound antibodies then lysed in Triton X-100, and the lysate applied to a monoclonal antibody coded ELISA well [46]. Yes Penicillin and penicillin derivatives are an example of this category. Drug-induced thrombocytopenia: an updated systematic review, 2006. To investigate potential drug effect on the absolute platelet count we included the four aforementioned antimicrobials in a mixed effect model. Of these, 98 (27.9%) never reached a platelet count 100 x 109/L. Quinine and quinidine are the most common causative drugs, but many other medications, including sulfonamide antibiotics and drug metabolites are implicated in the pathogenesis [21;44]. Antimicrobial-induced thrombocytopenia is frequently described in the literature among critically ill patients. Holler, K.A. eHealthMe is studying from 4,333 Unasyn users for its effectiveness, alternative drugs and more. Dosage of drugs is not considered in the study. Copenhagen HIV Programme at Rigshospitalet, University of Copenhagen, Copenhagen, Denmark, For analyses not involving death as an endpoint, follow-up time accrued from study entry to event or last available platelet count, whichever occurred first. The second part of the analysis combining both arms of the cohort was observational in nature. This signal was consistent with observed excess risk of relative thrombocytopenia associated with ongoing use of this drug. Curtis BR, Divgi A, Garritty M, Aster RH. Funding: Supported by grants from the Danish Research Council, The Lundbeck Foundation, Research Foundation for the Capital Region of Denmark, The Toyota Foundation, Brahms diagnostica (unrestricted grant), The Harboe Foundation, The A. P. Mller Foundation and the Idella Foundation. The ICUs participating in our study used heparin products as part of routine care in immobilized patients irrespective of which of the two randomized arms the patient was allocated to and which type of antimicrobial regiment the patient received. However, use of antimicrobials was fitted as a time-updated variables (i.e. There could be several reasons why ciprofloxacin in particular seems to affect the platelets in critically ill patients. All reported p values are two sided using a level of significance of 0.05. The primary analyses confirmed that patients randomized to the intervention group spent more days during follow-up receiving broad-spectrum antibiotics compared with the control group. Thrombocytopenia defined as absolute (one platelet count 100 x 109/L) or relative (20 % decrease in platelet count from study entry) was investigated. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final citable form. The evidence supporting the relationship between antimicrobial agents and thrombocytopenia is mainly based on case reports and laboratory studies; it is conversely rare that platelet-reactive antibodies are directly tested for [9-11]. In the absence of a more reliable method, the gold-standard for suspecting drug-induced thrombocytopenia is the observation of an increase in platelet count after discontinuation of the drug [9,10,12]. Tirofiban and eptifibatide are synthetic compounds that mimic or contain the Ang-Gly-Asp (RGD) motif and bind tightly to the RGD recognition site in GPIIb/IIIa (ligand-mimetic GPIIb/IIIa inhibitors); abciximab is a Fab fragment, of the chimeric human-murine monoclonal antibody 7E3 [53], specific for an epitope on GPIIIa [50;54]. Following the observation that drug-dependent antibodies bind to platelets via their Fab regions [32], subsequent studies have documented the mechanisms of drug-dependent antibody formation (Table 1) [21;22].

It works by killing the bacteria and preventing . Weltzien HU, Padovan E. Molecular features of penicillin allergy. DIT disorders can be a consequence of decreased platelet production (bone marrow suppression) or accelerated platelet destruction (especially immune-mediated destruction). Department of Anesthesia and Intensive Care, Aarhus University Hospital, Aarhus, Denmark, Affiliation Yes In subsequent observational analysis after combining the entire cohort, ciprofloxacin, and less so piperacillin/tazobactam, was found to be associated with thrombocytopenia compared with either using cefuroxime or no antibiotics.

In some instances, not only the drug itself but also its metabolites are responsible for the immune response in the patient. The frequency of DIT in acutely ill patients has been reported to be approximately 1925% [7;8]. Hansen, K.B. Table 1. Receiving piperacillin/tazobactam in combination with ciprofloxacin increased the risk; piperacillin/tazobactam vs. piperacillin/tazobactam + ciprofloxacin (RR: 1.15 [95% CI: 0.60 to 2.21] vs. 2.17 [95% CI: 1.10 to 4.26]. Hartmann, R. Albret, D.S. The members of the PASS study group are as follows: Central Coordinating Centre - J.U. Curtis BR, Swyers J, Divgi A, McFarland JG, Aster RH. Corticosteroids seem inefficient in the treatment of DIT [11]. Inclusion in an NLM database does not imply endorsement of, or agreement with, No, Is the Subject Area "Platelets" applicable to this article? It has been speculated that sensitivity reactions (including thrombocytopenia) seen in patients with rheumatoid arthritis who are treated with gold salts may be related to this mechanism [66], although other possibilities have been suggested. The onset of acute thrombocytopenia within hours of the first exposure to a GPIIb-IIIa inhibitor suggested that nonimmune factors might be responsible. RR-ratio=0 indicates no difference between the two groups. As noted, DIT disorders can be a consequence of decreased platelet production or accelerated platelet destruction. As a library, NLM provides access to scientific literature. RR-Ratio >1.0 indicates that the high-ex. A separate model was fitted for each of the exposure factors of interests. Call your doctor at once if you have: . Randomized trial allocated patients to antimicrobial treatment according to standard- of-care (SOC group) or drug-escalation in case of procalcitonin increases (high-exposure group). Heparin-induced thrombocytopenia in patients treated with low-molecular-weight heparin or unfractionated heparin. As critically ill patients are implicitly vulnerable, the discontinuation of a potential lifesaving drug is difficult and fraught with uncertainties regarding whether fluctuations in platelet count levels thereafter is explained by the treatment or resolution of the underlying condition it was used to treat. Accessibility Drugs are not the most common cause of hemolytic anemia. Gentilini G, Curtis BR, Aster RH. An official website of the United States government. Sensitivity to a metabolite of diclofenac as a cause of acute immune hemolytic anemia. Toxicology 2005;209:149153 [21]. In patients exposed only to a single drug, recovery after its discontinuation provides circumstantial evidence that the thrombocytopenia was caused by drug sensitivity [28;44]. Drenck; rhus-Centre (63) K.M. Thrombocytopenia is even more common with the oral GPIIb/IIIa inhibitors [52]. In order to identify a potential effect on platelet count not necessarily resulting in thrombocytopenia, an adjusted mixed effect models was built including platelet count during the first week as well as entire follow-up. Karl Landsteiners pioneering studies in the in the field of immunochemistry in the 1930's, showed that small molecules, such as drugs, organic compounds, peptides and oligosaccharides with a molecular weight of less than 25 kDa are not capable of inducing an immune response. Exposing critically ill patients to waste amount of broad-spectrum antimicrobials as part of a large randomized control trial, did not suggest a major effect of antimicrobials in inducing absolute nor relative thrombocytopenia nor was the absolute platelet count affected. The great diversity in timing is most likely explained by varying mechanisms causing drug-induced thrombocytopenia [7,10],including that prior exposure may have already sensitised some patients leading to more rapid effects upon reexposure [13].

Relative thrombocytopenia was observed more frequently than absolute thrombocytopenia, and is a more sensitive marker of more subtle changes in platelet count. Unadjusted analysis displaying the use of antimicrobials and occurrence of thrombocytopenia among the two randomized groups displayed as relative rate ratio (RR) during 28 day follow-up. Quinidine purpura: evidence that glycoprotein V is a target platelet antigen. Li X, Swisher KK, Vesely SK, George JN. Drug-induced thrombocytopenia: a systematic review of published case reports. A decrease in platelet count might protract clearance of infection [31]. DIT disorders can be a consequence of decreased platelet production (bone marrow suppression) or accelerated platelet destruction (especially immune-mediated destruction). As a service to our customers we are providing this early version of the manuscript. Department of Anesthesia and Intensive Care, Herlev University Hospital, Herlev, Denmark, Affiliation Patients with severe sepsis/septic shock had lower median platelet counts (x 109/L) within the first four days after study entry compared with patients without this condition; 157 [95% CI: 77 to 267] vs. 221 [95% CI: 149 to 326] respectively, p<0.0001. None of these had any influence on the design or conduct of the study; collection, management, analysis, and interpretation of the data; or the preparation, or approval of the manuscript. Patients in the high-exposure group received more antimicrobials including piperacillin/tazobactam, meropenem and ciprofloxacin compared with the SOC group, whereas cefuroxime was used more frequently in the SOC group (p<0.05). Kunicki TJ, Russell N, Nurden AT, Aster RH, Caen JP. As the knowledge regarding timing of ciprofloxacin- and piperacillin/tazobactam-induced thrombocytopenia is based on case reports, it is not possible to reliable estimate the time course of thrombocytopenia from that review. DIT can be distinguished from idiopathic thrombocytopenic purpura (ITP), a bleeding disorder . No, PLOS is a nonprofit 501(c)(3) corporation, #C2354500, based in San Francisco, California, US. Yes The association between current drug use and the risk of developing thrombocytopenia was investigated using a Poisson multivariable regression analysis. Absolute (one platelet count < 100 x 109/L) or relative (>=20 % decrease in platelet count from ICU admission) thrombocytopenia. broad scope, and wide readership a perfect fit for your research every time. Ampicillin and sulbactam combination is an antibiotic that belongs to the group of medicines known as penicillins and beta-lactamase inhibitors. Therefore, our findings suggests that antimicrobial drugs only marginally affect platelet counts in critically ill patients, and other factors such as severe infection, older age, surgery and chronic disease should be suspected as more likely candidates explaining this condition. Time-updated use of antimicrobials was included in the model.

During follow-up patients spent 11556 (44.8%) of 25776 days receiving antimicrobials. Mechanisms of immunologic reactions and red cell destruction. Drug-induced thrombocytopenia (DIT) is a relatively common clinical disorder. Drug-induced immune thrombocytopenia. These antibodies are heterogeneous and directed toward different epitopes on major platelet membranes glycoproteins (GPs), most often GPIb/IX, GPV and GPIIb/IIIa [23;3942] and platelet-endothelial cell adhesion molecule-1 (PECAM-1) [43] only when drug is present in soluble form [22]. Amiral J, Bridey F, Dreyfus M, et al. Save 2.20. These include the use of radiolabeled or fluorescein-labeled (platelet immunofluorescence test; PIFT) anti-IgG to detect platelet-bound immunoglobulin, enzyme-linked immunospecific assay (ELISA), flow cytometry and immunoprecipitation-Western blotting (IP-WB) [46;80;81].

Patients were followed until death or day 28. During follow-up, 337 patients (35.2% of patients at risk [95% CI: 33.2 to 37.2]) suffered absolute thrombocytopenia (one platelet count 100 x 109/L) of which 211 (18.0 % of patients at risk [95% CI: 16.2 to 19.0]) patients already had this condition at study entry. For more information about PLOS Subject Areas, click group have a relatively higher risk of occurrence of the asses variable and RR-Ratio <1.0 indicates relatively higher risk of patients in the SOC group of occurrence of the asses variable. Covariates included in the models were; randomization group (high-exposure group vs. SOC group), age 65 vs. <65 years, gender, APACHE II score (20 vs. <20), severe sepsis/septic shock at randomization (yes or no), surgical vs. medical patient, BMI (30 vs. <30) and chronic disease (Charlson score (2 vs. <2). Our study design did not allow us to address the potential mechanisms that may underlie our observation suggesting that exposure to specific antimicrobials may lead to smaller reductions in platelet counts. e81477. sharing sensitive information, make sure youre on a federal Coller BS. Curtis BR, McFarland JG, Wu GG, Visentin GP, Aster RH. It is also resistant to acid so it can be administered orally. In univariable analysis, a model including the exposure of interest, a linear term and a quadratic term for time as well as an interaction term between time and the exposure of interest was included. It has been proposed that antibodies from patients with abciximab-induced thrombocytopenia recognize either murine sequences incorporated into abciximab or conformational changes induced by abciximab in GPIIb/IIIa when abciximab binds [50]. However, single use of ciprofloxacin, and less so piperacillin/tazobactam, may contribute to a lower platelet count. It is imperative to provide rapid identification and removal of the offending agent before clinically significant bleeding or, in the case of heparin, thrombosis occurs. Importantly, this comparison was well-powered to detect even small differences in platelet counts. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. L. Mulla, U.

This particular analysis made is possible to detect the single effect of ciprofloxacin. Wrote the manuscript: MEJ JUJ MHB PIJ ACL JDl. Therefore, we built a model including drugs in combination with or without ciprofloxacin. Thrombocytopenia defined as absolute (platelet count 100x109/L) or relative (20% decrease in platelet count). Absolute and relative thrombocytopenia day 1-4 was associated with increased mortality (HR: 1.67 [95% CI: 1.30 to 2.14]; 1.71 [95% CI: 1.30 to 2.30], P<0.0001, respectively). A cut-off of 20% was chosen in order to include as many patients as possible for these analyses and at the same time avoid that a decrease in platelet count was due to measurement variability. within 24 hours of ICU admission) Severe sepsis/septic shock defined according to the American College of Chest Physicians/Society of Critical Care Medicine. Federal government websites often end in .gov or .mil. No interaction was detected for any of the drugs in question (piperacillin/tazobactam p= 0.1844; meropenem p=0.3806; ciprofloxacin p=0.0747; cefuroxime p=0.2020). In the past twenty years, much has been learned about the pathogenesis of DITP. 53 patients were excluded due to missing data on platelet counts at study entry (i.e. (2) Consider HIT. The second, an oral form called sultamicillin, is marketed under the brand name Ampictam outside the United States, and generic only in the United States. Flow cytometry is a rapid and highly sensitive technique for the detection of platelet-reactive antibodies induced by several drugs, including, but not limited to, quinine, quinidine and sulfamethoxazole [24;80]. and transmitted securely. This means that the endpoint of absolute and/or relative thrombocytopenia would provide a signal of excess risk if an agent actually resulted in the endpoint. DIT can be distinguished from idiopathic thrombocytopenic purpura (ITP), a bleeding disorder caused by thrombocytopenia not associated with a systemic disease, based on the history of drug ingestion or injection and laboratory findings. Peterson JA, Nyree CE, Newman PJ, Aster RH. Quinine-dependent antibodies bind a restricted set of epitopes on the glycoprotein Ib-IX complex: characterization of the epitopes. In analysis using all platelet measurements over the entire study period of 28 days, no difference in average platelet count was detected. Lee DH, Warkentin TE. The precise mechanism whereby ciprofloxacin might affect the platelets is unknown. Several antimicrobials have been implicated, although experimental evidence to demonstrate causality is limited. Consistent with the literature [10,15,16], current use of ciprofloxacin and/or piperacillin/tazobactam was associated with relative thrombocytopenia, whereas none of the drugs were associated with absolute thrombocytopenia. In order to assess the consistency of the observed differences between specific antimicrobials, we performed separate analyses in the subsets of people with or without septic shock at entry. Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).. Unasyn may cause serious side effects. Penicillins constitute a large family of compounds whose common structural basis is a beta-lactam ring condensed to a thiazolidine ring. The UK is the first country to allow OTC access to Sanofi's tadalafil-based erectile dysfunction drug Cialis following a successful switch. 1 The incidence of ITP is 6 per 100,000 adults/year. Thrombocytopenia (absolute and relative) occurred during the first 4 days after study entry in the majority of patients. Mueller-Eckhardt C, Salama A.

The publisher's final edited version of this article is available at, drug-dependent, drug-induced, immune-thrombocytopenia, thrombocytopenia, autoimmunity. Visentin GP, Newman PJ, Aster RH. Though, with an incidence of 0.1-0.5% [13], heparin-induced thrombocytopenia may have occurred in approximate 5 to 10 of the patients in our study. Curtis BR, Kaliszewski J, Marques MB, et al. Therefore, it is unlikely that unnoticed use of heparin is a relevant confounder that explains our findings. A potentially compounding factor may be severe infection known to induce platelet dysfunction which a great number of the patients in our study suffered from [6]. Department of Anesthesia and Intensive Care, Hvidovre University Hospital, Hvidovre, Denmark, Affiliation Remarkably, antibodies in an individual patient are often highly specific for a single GP. Precise localization, however, has been achieved only for a limited number of quinine-dependent antibodies shown to bind to a restricted 70 amino acid domain of GPIIIa located just N-terminal from a well-defined disulfide-bonded region that is resistant to protease digestion [46] and further restricted to a 17-amino acid sequence (AA residues 5066) [48]. Patients with quinine-induced immune thrombocytopenia have both "drug-dependent" and "drug-specific" antibodies.

Piperacillin/tazobactam, meropenem, cefuroxime and ciprofloxacin were the mostly used agents with; 3759 (15%), 1981 (8%), 2986 (12%) and 5660 (22%) days of total follow-up, respectively. McFarland JG. Since ciprofloxacin is often prescribed in combination with piperacillin/tazobactam we hypothesized that the association between piperacillin/tazobactam and relative thrombocytopenia was driven by the thrombocytopenic induction of ciprofloxacin. Main characteristic at study entry. Copyright: 2013 Johansen et al. Acute interstitial nephritis, hepatitis, drug fever. Since combination of ciprofloxacin and piperacillin/tazobactam is frequent, we created a separate model to compare the risk of relative thrombocytopenia associated with currently receiving piperacillin/tazobactam with or without ciprofloxacin; no difference was found between use of the single drug or as part of combination not including ciprofloxacin. Bozec L, Bierling P, Fromont P, et al. https://doi.org/10.1371/journal.pone.0081477.s002, https://doi.org/10.1371/journal.pone.0081477.s003. Of them, 170 (49.6% of patients at risk [95% CI: 47.0 to 52.2]) and 143 (41.7% of patients at risk [95% CI: 38.8 to 41.7]) suffered absolute and relative thrombocytopenia, respectively, within the first 4 days after study entry. 4 UNI | 4.95 per 1UNI. Primary Immune Thrombocytopenic Purpura (ITP) is an autoimmune disorder characterized by increased platelet destruction and decreased platelet production.
