About Us

Clinical Services

All members are actively involved in providing clinical consultative services in Allergy and Immunology to the community.

A major initiative at St. Paul’s Hospital is to improve the care of patients with primary immunodeficiency.  We have been at the forefront of providing home subcutaneous immunoglobulin therapy (SCIG) as well as maintaining our intravenous immunoglobulin therapy (IVIG) at St. Paul’s Hospital. The Primary Immunodeficiency Transition Clinic led by Drs. Catherine Biggs and Persia Pourshahnazari has not only provided advanced diagnostic tests including exploring the genetic origins of many immune diseases but provides team based care for patients previously followed at BC Children’s.

Our division has created many clinical programs which are the first of its kind in the country. Drs Raymond Mak and Juan Ruiz have established the first Perioperative Anaphylaxis Clinic in Canada at Vancouver General Hospital which services the entire province. Dr Mak also helped establish the MED Safe clinic, a unique interdisciplinary adverse drug reactions clinic with a focus on severe cutaneous adverse reactions . This clinic combines translational research with clinical care. Dr. Mak is also involved in Canada’s first dedicated pregnancy penicillin allergy clinic at BC Women’s hospital.

Our entire faculty provides community and hospital care for patients with a wide variety of allergy and immunology conditions.  These include: allergic rhinitis, asthma, aspirin/NSAID sensitive asthma (also known as aspirin-exacerbated respiratory disease-AERD), chronic sinusitis, nasal polyps, drug allergy, food allergy, insect sting allergy, atopic dermatitis (eczema), urticaria (hives), angioedema, anaphylaxis, mast cell disorders such as mastocytosis and mast cell activation syndrome, eosinophilic esophagitis, other eosinophilic disorders, hereditary angioedema and immunodeficiency conditions such as common variable immunodeficiency (CVID) and IgA deficiency.

Many members of our Faculty are also actively involved in local, national and international committees dealing with their areas of interest.
