Treatment of acute hypersensitivity reaction

Uitgangsvraag

Wat is de optimale behandeling voor acute overgevoeligheidsreacties op contrastmiddelen?

Aanbeveling

Acute allergische reacties verschillen in ernst; de aanbevelingen zijn per ernst van de situatie geformuleerd.

 

Bij anafylactische reactie:

  • Geef adrenaline intramusculair. Let op de juiste dosering:
    • >25 kg lichaamsgewicht 300 microgram adrenaline (adrenaline auto-injectors beschikbaar, zoals de Epipen® or Jext®),
    • 7.5-25 kg lichaamsgewicht 150 microgram adrenaline (adrenaline auto-injectors beschikbaar, zoals de Epipen Junior® or Jext®),
    • < 7.5 kg lichaamsgewicht , 10 mcg/kg, overeenkomend met 0.1 ml/kg uit 1mg/10ml adrenaline ampul (1:10.000).
    • Indien het gewicht niet bekend is: ≥ 6 jaar 300 microgram (Epipen® or Jext®), < 6 jaar 150 microgram (Epipen Junior® or Jext®).
  • Geef 15 liter/minuut zuurstof via een non-rebreathing masker.
  • Alarmeer het (kinder)reanimatie team (naam varieert per ziekenhuis).
  • Als de symptomen niet afnemen of verergeren, kan een tweede dosis adrenaline nodig zijn. Een tweede injectie kan 5-15 minuten na de eerste dosis gegeven worden.

Bij niet-anafylactische acute overgevoeligheidsreacties:

  • Overleg met een kinderarts over verdere behandeling en/of beleid.

Overwegingen

Advantages and disadvantages of the intervention and quality of evidence

The work group conducted a systematic review of the optimal treatment for acute hypersensitivity reactions to contrast agents. No articles were found that met the inclusion criteria. Therefore, no conclusions could be drawn about the effects of treatment for acute hypersensitivity reactions on the outcome measures duration of acute allergic reaction, severity of symptoms, morbidity, mortality, costs, ICU admission, length of stay. Therefore, a knowledge gap exists on this topic.

 

As there are no comparative studies investigating the optimal treatment for acute hypersensitivity reactions to contrast agents in children, the recommendations in this national guideline are based mainly on expert opinion in combination with two other sources of relevant literature. The first is the Dutch National Advanced Paediatric Life Support book (Turner, 2022). This is considered the standard with regard to dealing with life threatening pediatric conditions, including anaphylaxis.

We also used the adult guideline for the treatment of acute hypersensitivity reactions to contrast media (NVvR, 2020). We adhere to the adult guidelines as much as possible, taking into account differences between adults and children in physiology and treatment options. First, we describe key differences to consider, followed by the treatment options.

 

Differences between adults and children

  • The airways in children differ from those in adults in diameter and shape, making children especially vulnerable to airway narrowing due to anaphylaxis.
  • Unlike adults, children in general have better developed mechanisms of compensation. Unfortunately, the degree of sickness can easily be underestimated.
  • In children medication is based on body weight in kilograms. If this is unknown, age is used as a surrogate to estimate body weight.
  • Like in adults, APLS guidelines with an ABC-type approach is used (NVvR, 2020).

Acute hypersensitivity reactions

Patients who develop an acute hypersensitivity reaction to contrast agents may have a variety of symptoms. Varying from mild symptoms, for example a rash, to severe potentially life-threatening reactions with symptoms like (airway) edema, inspiratory and expiratory stridor, hypotension, collapse and persistent vomiting. These severe reactions are also called anaphylaxis. Since the frequency of severe hypersensitivity reactions to contrast agents is quite rare, the guideline development group focuses on three simple but effective ways to stabilize the patient while waiting for a pediatric resuscitation team. Further treatment is best done by a pediatrician or pediatric anesthesiologist. The three measures to treat anaphylaxis are described in more detail below. For non-anaphylactic acute hypersensitivity reactions to contrast agents, the guideline development group recommends consulting a pediatrician.

 

Three measures to treat anaphylaxis

Anaphylaxis or severe hypersensitivity reactions are potentially life-threatening and it is important to start treatment as soon as possible. Quick administration of intramuscular adrenaline will swiftly alleviate symptoms. The second most important treatment will be administration of 15 liter per minute of oxygen, via a non-rebreathing mask. It is important to have smaller masks suitable for children on hand in the CT room. However, since the effect of the adrenaline may be temporary, specialized pediatric care is required. So third, a (pediatric) resuscitation team needs to be called to assist immediately (the exact name and composition of this team differs between hospitals). The goal of treatment for anaphylaxis is to stabilize the patient, while waiting for a pediatric resuscitation team. Further recommendations regarding the treatment of children with hypersensitivity reactions are beyond the scope of this guideline. Pediatricians will follow APLS guidelines for further treatment of hypersensitivity reactions.

Unlike the treatment of anaphylaxis in adults, clemastine is no longer recommended for treatment of anaphylaxis in children. It’s known to cause hypotension and drowsiness; this last side effect can further compromise airway patency.

 

Adrenaline administration

In the setting of anaphylaxis, adrenaline should be administered into the muscle (intramuscular injection). The recommended dose is:

  • >25 kg body weight: 300 microgram adrenaline (adrenalin auto-injectors available, such as Epipen® or Jext®),
  • 7.5-25 kg body weight: 150 microgram adrenaline (adrenalin auto-injectors available, such as Epipen Junior® or Jext®),
  • < 7.5 kg body weight: 10 mcg/kg, (equals 0.1 ml/kg from 1mg/10ml adrenaline vial ( 1:10,000).
  • When weight is unknown: ≥ 6 years 300 microgram (adrenalin auto-injectors available, such as Epipen® or Jext®), < 6 years 150 microgram (adrenalin auto-injectors available, such as Epipen Junior® or Jext®).
  • When symptoms do not decrease or progress a second dose of adrenalin can be necessary. A second injection can be given 5-15 minutes after the first dose.

Adrenaline is available in vials, from which the solution must be aspirated into a syringe before it can be administered to the child. Another option is to use an adrenalin auto-injector, in which an adrenaline solution is already in a syringe. These devices can be spring loaded, such as the Epipen®. An adrenaline auto-injector is used to administer adrenaline intramuscularly in an acute setting. Since most healthcare providers in radiology do not use needles and syringes to administer medication on a daily basis, and since time is of the utmost essence, the guideline development group strongly advises use of an adrenalin auto-injector despite a higher cost (see cost paragraph below for more details).

 

Patient (and their caretakers) values and preferences

Acute hypersensitivity reactions to contrast media are a cause of concern for patients and their caregivers, especially if they have experienced acute hypersensitivity reactions in the past. It is important to distinguish severe reactions such as anaphylaxis from mild reactions such as rash, since treatment and response should be in proportion. In case of severe reactions, namely anaphylaxis, the focus is on swift intervention to reduce the immediate concern (airway restriction), meanwhile ensuring the correct expertise is sent by contacting a pediatric resuscitation team for any further decisions on treatment. In case of mild acute hypersensitivity reactions, there is more time to formulate a treatment strategy and, if necessary, consult the appropriate experts.

 

Costs

It is important to act quickly and effectively to prevent serious complications from acute hypersensitivity reactions, and reduce associated additional healthcare costs both in the short and long term. Most of the recommendations in this guideline lead no or little additional costs. Oxygen is usually already available in CT suites and non-rebreathing masks cost around 5 euros each. Only for adrenaline administration in children weighing >10 kg does the guideline development group strongly advice a higher priced alternative, based on the ease of use and thus more time efficient administration. For example, the use of adrenalin auto-injectors such as the Epipen® (cost 38-42 euros) instead of adrenaline injection using vials (3 euros for 1mg/1ml solution) (Zorginstituut Nederland, n.d.). For children weighing less than 10 kilograms, the only option is to administer the (=weight adjusted) amount of adrenaline with a syringe.

 

Acceptability, feasibility and implementation

The guideline development group does not anticipate any acceptance or feasibility issues. The triad adrenaline / high flow oxygen / calling for help is a simple but effective strategy in cases of anaphylactic acute hypersensitivity reactions. High oxygen flow is already standard in the treatment of anaphylactic acute hypersensitivity reactions in adults. Ensuring smaller non-rebreathing masks suitable for children are present should not provide problems as these are already used and readily available in hospital. Similarly, the guideline development group anticipates it will be feasible to ensure the way to contact the paediatric resuscitation team is clearly signposted near the CT scanner and contact details for a paediatrician are available. Regarding adrenaline, many radiology departments are already familiar with the use of an adrenalin auto-injectors. Therefore, the introduction of an Adrenaline auto-injector (for children who weigh more than 7.5 kilograms) is expected to be acceptable and feasible. If contrast media is also given to children who weigh less than 7.5 kilograms, a 0,1mg/10 ml vial of adrenaline (with needles and syringes) also needs to be present.

In terms of implementation, given the rarity of these types of reactions it is important to provide adequate training of personnel on how to handle acute contrast reactions in children. Thus, ensuring the correct level of expertise is maintained to act when necessary.

 

Rationale of the recommendation: weighing arguments for and against the interventions

Unfortunately, there were no comparative studies investigating the optimal treatment for acute hypersensitivity reactions to contrast agents in children. Therefore, the recommendations in this national guideline are based mainly on expert opinion in combination with a current standard book on Advanced Paediatric Life Support (Turner, 2022) and the existing adult guideline for the treatment of acute hypersensitivity reactions to contrast media (NVvR, 2020).

 

Since the airways in children differ from those in adults in diameter and shape, this makes children especially vulnerable to airway narrowing due to anaphylaxis. To treat airway narrowing due to an anaphylactic acute hypersensitivity reaction to contrast media, adrenaline should be administered intramuscularly. In addition to this, high flow oxygen should be given by means of a non-rebreathing mask. Since anaphylaxis is a paediatric emergency, advanced paediatric life support expertise is required immediately, to further treat the child and prevent rapid deterioration of the condition of the child.

 

Overall, there is consensus in our guideline development group that these three basic measures (adrenaline, oxygen, call for help) are critical in the primary treatment of life-threatening anaphylaxis. In case of mild acute hypersensitivity reactions, there is more time to formulate a treatment strategy and, if necessary, consult the appropriate experts.

 

The guideline development group does not anticipate any acceptance, feasibility or implementation issues.

Onderbouwing

Anaphylaxis due to intravenous contrast media is rare in children. Currently, radiologists use a combination of adult guidelines and experience to treat acute hypersensitivity reactions to contrast media in children. However, children are a heterogeneous population in terms of age and background. Children have a different anatomy of the upper airways, making them especially vulnerable to airway constriction due to anaphylaxis. Also, since children come in different shapes and sizes, tailormade approach based on body weight and anatomical differences in comparison to adults, is required. Therefore, the current guideline describes the optimal treatment for acute hypersensitivity reactions to contrast media in children.

Level of evidence of the literature

The level of evidence could not be determined as no studies were included in the analysis of the literature.

A systematic review of the literature was performed to answer the following question:

What are the effects of different measures to reduce symptoms of hypersensitivity reactions in children (<18 years of age) undergoing radiological examinations with contrast media?

 

P(atients): Children (<18 years) with acute hypersensitivity reaction after administration of contrast media;
I(ntervention): Treatment, antihistamines, corticosteroids, epinephrine, adrenalin, dopamine, norepinephrine, noradrenalin, histamine H1 antagonists, histamine H2 antagonists, H1 antihistamines, H2 antihistamines, adrenergic beta-2 receptor agonists, glucocorticoids, management/treatment of hypersensitivity reactions/allergic reactions after contrast media, antihistamines, volume resuscitation, bronchodilators;
C(ontrol): Conservative treatment or comparison of interventions mentioned above;
O(utcome):

Curation of acute allergic reactions, severity of complaints, morbidity, mortality, costs, hospitalization in an IC-unit, length of stay.

 

Relevant outcome measures

The guideline development group considered morbidity, mortality, and hospitalization in an IC-unit as critical outcome measures for decision making; and duration of acute reaction, length of stay and costs, as outcome measures for decision making.

 

A priori, the guideline development group did not define the outcome measures listed above but used the definitions used in the studies.

 

The guideline development group defined the following as a minimal clinically (patient) important difference:

  • Duration of acute allergic reaction: 0.5 SD (continuous);
  • Severity of complaints: 0.5 SD (continuous);
  • Morbidity: relative risk <0.91 or >1.10;
  • Mortality: relative risk <0.95 or >1.05;
  • Hospitalization in an IC-unit: relative risk <0.80 or >1.25;
  • Length of stay in hospital: 0.5 SD (continuous);
  • Costs: 0.5 SD (continuous);

Search and select (Methods)

The databases Medline (via OVID) and Embase (via Embase.com) were searched with relevant search terms from 1990 until 14-03-2023. The detailed search strategy is depicted under the tab Methods. The systematic literature search resulted in 147 hits. Studies were selected based on the following criteria:

  • Systematic review, randomized controlled trial or observational research comparing treatment for acute hypersensitivity reactions to conservative treatment or another kind of treatment.
  • Including children (<18 years) with an acute hypersensitivity reaction after administration of contrast media.
  • Reporting at least one of the following outcome measures: duration of acute allergic reaction, severity of complaints, morbidity, mortality, costs, hospitalization in an IC-unit, length of stay.

26 studies were initially selected based on title and abstract screening. After reading the full text, all studies were excluded (see the table with reasons for exclusion under the tab Methods), and no studies were included.

Inbreng patiëntenperspectief

Input of patient’s perspective

The guideline does not address a specific child patient group, but a diverse set of diagnoses. Therefore, it was decided to invite a broad spectrum of patient organisations for the stakeholder consultation, and invite the patient organisation Kind & Ziekenhuis (translated as Child and Hospital Foundation) in the Advisory group. The stakeholder consultation was performed at the beginning of the process for feedbacking on the framework of subjects and clinical questions addressed in the guideline, and during the commentary phase to provide feedback on the concept guideline. The list of organisations which were invited for the stakeholder consultation can be requested from the Kennisinstituut van de Federatie Medisch Specialisten (secretariaat@kennisinstituut.nl). In addition, patient information on safe use of contrast media in children was developed for Thuisarts.nl, a platform to inform patients about health and disease.

Implementatie

Implementation

During different phases of the guideline development, implementation and practical enforceability of the guideline were considered. The factors that could facilitate or hinder the introduction of the guideline in clinical practice have been explicitly considered. The implementation plan can be found in the ‘Appendices to modules’. Furthermore, quality indicators were developed to enhance the implementation of the guideline. The indicators can also be found in the ‘Appendices to modules’.

Werkwijze

Methodology

AGREE

This guideline has been developed conforming to the requirements of the report of Guidelines for Medical Specialists 2.0 by the advisory committee of the Quality Counsel (www.kwaliteitskoepel.nl). This report is based on the AGREE II instrument (Appraisal of Guidelines for Research & Evaluation II) (www.agreetrust.org), a broadly accepted instrument in the international community and based on the national quality standards for guidelines: “Guidelines for guidelines” (www.zorginstituutnederland.nl).

 

Identification of subject matter

During the initial phase of the guideline development, the GDG identified the relevant subject matter for the guideline. The framework is consisted of both new matters, which were not yet addressed in Part 1, 2 and 3 of the guideline, and an update of matters that were subject to modification (for example in case of new published literature). Furthermore, a stakeholder consultation was performed, whre input on the framework was requested.

 

Clinical questions and outcomes

The outcome of the stakeholder consultation was discussed with the GDG, after which definitive clinical questions were formulated. Subsequently, the GDG formulated relevant outcome measures (both beneficial and harmful effects). The GDG rated the outcome measures as critical, important and of limited importance (GRADE method). Furthermore, where applicable, the GDG defined relevant clinical differences.

 

Search and select

For clinical questions, specific search strategies were formulated, and scientific articles published in several electronic databases were searched. First, the studies that potentially had the highest quality of research were reviewed. The GDG selected literature in pairs (independently of each other) based on the title and abstract. A second selection was performed by the methodological advisor based on full text. The databases used, selection criteria and number of included articles can be found in the modules, the search strategy can be found in the appendix.

 

Quality assessment of individual studies

Individual studies were systematically assessed, based on methodological quality criteria that were determined prior to the search. For systematic reviews, a combination of the AMSTAR checklist and PRISMA checklist was used. For RCTs the Cochrane risk of bias tool and suggestions by the CLARITY Group at McMaster University were used, and for cohort studies/observational studies the risk of bias tool by the CLARITY Group at McMaster University was used. The risk of bias tables can be found in the separate document “Appendices to modules”.

 

Summary of literature

The relevant research findings of all selected articles were shown in evidence tables. The evidence tables can be found in the separate document “Appendices to modules”. The most important findings in literature were described in literature summaries. When there were enough similarities between studies, the study data were pooled.

 

Grading quality of evidence and strength of recommendations

The strength of the conclusions of the included studies was determined using the GRADE-method. GRADE stands for Grading Recommendations Assessment, Development and Evaluation (see http://www.gradeworkinggroup.org) (Atkins, 2004). GRADE defines four levels for the quality of scientific evidence: high, moderate, low, or very low. These levels provide information about the certainty level of the literature conclusions (http://www.guidelinedevelopment.org/handbook).

The evidence was summarized in the literature analysis, followed by one or more conclusions, drawn from the body of evidence. The level of evidence for the conclusions can be found above the conclusions. Aspects such as expertise of GDG members, local expertise, patient preferences, costs, availability of facilities and organisation of healthcare are important to consider when formulating a recommendation. These aspects are discussed in the paragraph “Justifications”. The recommendations provide an answer to the clinical question or help to increase awareness and were based on the available scientific evidence and the most relevant “Justifications”.

 

Appendices

Internal (meant for use by scientific society or its members) quality indicators were developed during the conception of the guideline and can be found in the separate document “Appendices to modules”. In most cases, indicators were not applicable. For most questions, additional scientific research on the subject is warranted. Therefore, the GDG formulated knowledge gaps to aid in future research, which can be found in the separate document “Appendices to modules”.

 

Commentary and authorisation phase

The concept guideline was subjected to commentaries by the involved scientific societies. The list of parties that participated in the commentary phase can be requested from the Kennisinstituut van de Federatie Medisch Specialisten (secretariaat@kennisinstituut.nl).
The commentaries were collected and discussed with the GDG. The feedback was used to improve the guideline; afterwards the guideline was made definitive by the GDG. The final version of the guideline was offered to the involved scientific societies for authorization and was authorized.
