To characterise patients with systemic reactions and anaphylaxis with an acute serum tryptase of ≥14 μg/L against recently published World Allergy Organisation (WAO) diagnostic criteria. To also perform a clinical audit to assess adherence to National Institute of Health and Care Excellence (NICE) guideline recommendations regarding serial tryptase measurements and specialist referral. ⋯ The correlation between acute serum tryptase and severity of anaphylaxis/systemic reactions is weak. A significant proportion of patients with raised acute serum tryptase had mild reactions which did not meet WAO criteria for anaphylaxis and this may reduce the specificity of the test. The commonest aetiology in this cohort was idiopathic followed by drug and food allergies. NICE guidelines relating to serial tryptase measurements and specialist referral were not followed, and there is an urgent need to raise the awareness among clinicians involved in the management of anaphylaxis.

Integrin αv subunits are involved in tumour angiogenesis and tumour progression in various types of cancers. Clinical trials evaluating agents targeting integrin αv are ongoing. Integrin αv expression has been reported in several cancers in association with tumour progression or poor survival. However, no study has addressed the prognostic influence of integrin αv expression on survival of patients with colorectal cancer (CRC). ⋯ Overexpression of integrin αv is associated with advanced T and N stage and as an independent prognostic factor in CRC.
