The article offers a guide on identifying immunodeficiency. HIV infection is cited as the most common cause of secondary immunodeficiency. The epidemiology of immunodeficiency and the high rate of delay in diagnosis in Great Britain are tackled. Patients suffering from severe, persistent, unusual or recurrent infections are recommended to be considered for immunodeficiency investigation. The common first-line investigation comprises of full blood count, immunoglobulins, serum complement C3/C4, and human immunodeficiency virus (HIV) test (FISH).

Pollen food syndrome (PFS) is a highly prevalent food allergy affecting pollen‐sensitized children and adults. Sufferers experience allergic symptoms when consuming raw plant foods, due to the homology between the pollen allergens and unstable proteins in these foods. The triggers involved can vary depending on the pollen sensitization, which in turn is affected by geographical location. The British Society of Allergy and Clinical Immunology (BSACI) Standards of Care Committee (SOCC) identified a need to develop a guideline for the diagnosis and management of PFS in the United Kingdom (UK). Guidelines produced by the BSACI use either the GRADE or SIGN methodology; due to a lack of high‐quality evidence these recommendations were formulated using the SIGN guidelines, which is acknowledged to be less robust than the GRADE approach. The correct diagnosis of PFS ensures the avoidance of a misdiagnosis of a primary peanut or tree nut allergy or confusion with another plant food allergy to non‐specific lipid transfer proteins. The characteristic foods involved, and rapid‐onset oropharyngeal symptoms, mean PFS can often be diagnosed from the clinical history alone. However, reactions involving tree nuts, peanuts and soya milk or severe/atypical reactions to fruits and vegetables may require additional diagnostic tests. Management is through the exclusion of known trigger foods, which may appear to be simple, but is highly problematic if coupled with a pre‐existing food allergy or for individuals following a vegetarian/vegan diet. Immunotherapy to pollens is not an effective treatment for PFS, and although oral or sublingual immunotherapy to foods seems more promising, large, controlled studies are needed. The typically mild symptoms of PFS can lead to an erroneous perception that this condition is always easily managed, but severe reactions can occur, and anxiety about the onset of symptoms to new foods can have a profound effect on quality of life.

Specifically, the risk of AE, ARC, SLE, ATD and vitiligo is uniformly higher amongst British ethnic minority groups in comparison with the White population.

However, ALK has advised that the Pharmalgen product line will be discontinued, with a plan to substitute with Alutard SQ Bee and Wasp Venom products. In contrast to Pharmalgen which was supplied in a single vial that required manual dilution during updosing, Alutard SQ Bee and Wasp Venoms are supplied in two product kits. There is sufficient existing Pharmalgen product to allow all patients currently being updosed to reach maintenance therapy, but once on maintenance they should all be switched over to Alutard SQ.
