Allergy, Immunology and Rheumatology
We offer comprehensive inpatient and outpatient evaluations and follow-up for various disorders of allergy and immune regulation in children. Our physicians are regularly sought out for their consultation services by health care professionals in Northern California and Nevada.
Our pediatric allergy team offers evaluations and management of various allergic disorders, including:
- seasonal allergies
- food allergies
- drug allergies
- allergic asthma
- stinging insect allergy
The team utilizes skin prick testing, spirometry, laboratory analysis and family education/training to further aid in the development of their treatment plans. Food and drug challenge clinics are conducted weekly to help delineate the establishment of tolerance to these exposures.
Our Immunology service sees patients and offers treatment recommendations for children with a history of recurrent, severe, or unusual infections, recurrent fevers, low immunoglobulins, and for immune dysregulation syndromes.
Because of the complexity of many of these patients, the Immunology team has established a multidisciplinary presence within the healthcare system. Specialty clinics are offered in conjunction with other services and include 22q11.2 deletion syndrome clinics (with ENT, Genetics, Physical Therapy/Occupational Therapy and Developmental Pediatrics), Early Onset Inflammatory Bowel Disease clinics (with GI), as well as Recalcitrant Cytopenia clinics (with Hematology). In addition, we are now a primary Newborn Screening (NBS) Immunology Center, performing evaluations of children who have a concern for an immune deficiency based on their newborn screening results.
Our Rheumatology service is available to evaluate and manage patients with suspected or diagnosed rheumatologic conditions including:
- juvenile idiopathic arthritis
- systemic lupus erythematosus
- juvenile dermatomyositis
- systemic sclerosis
- periodic fever syndromes
Comprehensive articular exams, along with laboratory analysis and imaging, are all offered in our clinics to help with treatment plans.
Victoria Dimitriades sees patients for the following clinical conditions: food allergy, seasonal allergies, atopic dermatitis, recurrent hives, drug reactions, stinging insect reactivity, immunology, recurrent infections, recurrent fevers, low immunoglobulins and periodic fever syndromes. Her research interests include specific antibody deficiency and recurrent infections of the ears, sinuses and lungs. Additionally, she has an interest in patients with inflammation related to immune deficiency as well as hereditary periodic fever syndromes.

He provides medical care to children with rheumatologic conditions such as juvenile idiopathic arthritis, lupus, and juvenile dermatomyositis among others. He has a clinical interest in pediatric systemic sclerosis and pediatric lupus.
