Which of the following management strategies for allergic disease has been shown to influence the natural course of the disease?
allergen avoidance
allergen-specific immunotherapy
antihistamines
patient education
topical steroids.
In the UK, allergen immunotherapy is used in the treatment of which of the following conditions?
allergic rhinitis
atopic dermatitis
food allergy
idiopathic anaphylaxis
latex allergy.
Which of the following statements regarding immunoglobulin therapy is correct?
According to Department of Health figures, expenditure on immunoglobulin A is less than £100 million annually.
British plasma is used as a source of immunoglobulin production.
Immunoglobulin can be prescribed for any autoimmune or inflammatory condition.
The Demand Management Programme aims to secure immunoglobulin supplies for patients in greatest clinical need.
There are no safety concerns related to the use of immunoglobulin.
Which of the following statements is correct regarding ‘blue indications’ for immunoglobulin?
Alternative treatments should not be considered, even at times of immunoglobulin shortage, for patients with blue indication diseases.
Blue indications are considered highest priority because of risk to life without treatment.
Blue indications are divided into likely immune-mediated diseases with limited evidence of immunoglobulin efficacy and presumed immune-mediated diseases with little or no evidence of immunoglobulin efficacy.
Blue indications are those conditions where there is evidence of benefit from immunoglobulin but for which there may be alternative treatment options.
Blue indications have no evidence base on which to support immunoglobulin treatment.
A 62-year-old male patient presented with recurrent episodes of feeling faint, associated with flushing, abdominal cramps and diarrhoea. The patient had been rushed to the emergency department with an anaphylactic reaction to a wasp sting 6 months earlier. On examination, there was no visible rash and no palpable organomegally. A full blood count was unremarkable. You suspect a mast cell activation disorder. What would be the most appropriate next investigation?
bone marrow biopsy
CT chest, abdomen, pelvis
screening for a D816V KIT mutation of an EDTA blood sample[c1]
serum tryptase
specific IgE to wasp venom.
A 45-year-old female patient presented with red brown macules increasing in number over the abdomen and thighs over the preceding 6 months. The patient noted that when the rash was rubbed, some of the lesions became raised and itchy. She was otherwise well with no associated symptoms, such as flushing or diarrhoea. There was no history of anaphylaxis. A skin biopsy was performed and a diagnosis of urticaria pigmentosa was confirmed. Serum tryptase was <14 ng/mL. Which of the following treatments are likely to benefit the patient at this stage?
antihistamines
dairy free diet
hydrocortisone ointment
imatinib
sodium cromoglicate.
Skin prick testing is generally helpful for the diagnosis of:
allergy to nonsteroidal anti-inflammatory drugs
angiotensin-converting enzyme inhibitor angioedema
opiate reactions
penicillin allergy
Stevens-Johnson syndrome.
Which of the following is correct about angiotensin-converting enzyme (ACE) inhibitor angioedema?
Angiotensin receptor blockers must not be tried.
Episodes always stop immediately following discontinuation of the ACE inhibitor.
Episodes can happen several years after starting the ACE inhibitor.
Patients should be referred for specialist review.
The ACE inhibitor should be continued with addition of antihistamine prophylaxis.
Clinically significant secondary antibody deficiency:
always occurs with B-cell depleting therapies
can be managed with prophylactic antibiotic therapy
can lead to silent end-organ damage, eg bronchiectasis
typically presents with recurrent infections with staphylococcus
usually occurs in solid organ malignancies.
Rituximab therapy-induced hypogammaglobulinaemia
depletes plasma cells, resulting in loss of antibody production
is managed with prophylactic antibiotic therapy
is more likely with multiple cycles of therapy
is significant in the majority of patients treated with the drug
is usually permanent.
