Andrej Petrov graduated cum laude from the University Of Belgrade School of Medicine in Belgrade, Serbia. He completed residency in Internal Medicine at Harrisburg Hospital, Pennsylvania and fellowship in Allergy and Clinical Immunology at the University of Pittsburgh Medical Center (UPMC). He has served as a Medical Director of Allergy and Clinical Immunology at UPMC Presbyterian/Montefiore since 2007. Additionally, he became a chief of Allergy at UPMC Shadyside in 2012. He serves as an associate fellowship program director in allergy and immunology and supervises training of allergy and pulmonary fellows in adult allergy and clinical immunology. Dr. Andrej Petrov is board certified in Allergy and Clinical Immunology and Internal Medicine.

Dr. Petrov is reviewing a chest CT with allergy-immunology fellows.

Dr. Petrov is discussing indications for flexible nasal endoscopy and laryngoscopy with allergy-immunology fellows.

Clinical Interests

During his tenure, Dr. Petrov has worked to establish and grow the allergy, asthma and immunology outpatient and inpatient clinical programs. This effort has led to remarkable growth of the outpatient allergy, asthma and immunology clinic in the Comprehensive Lung Center with a focus on difficult to manage clinical conditions including co-existent upper and lower airway diseases (chronic sinusitis and bronchiectasis in immunodeficiency patients, Samter’s triad [ nasal polyps, asthma and aspirin allergy], evaluation of multifactorial causes of chronic cough, and conditions that mimic or complicate asthma such as vocal cord dysfunction), adult immunodeficiency (including acquired immunodeficiency secondary to immunosuppressive medications), urticaria (hives) and angioedema (swelling), anaphylaxis and systemic mastocytosis, food allergy, and atopic and contact dermatitis. Dr. Petrov has implemented outpatient rapid desensitization protocols for patients with allergic rhinitis (environmental allergies) and bee sting allergy. He has introduced novel outpatient drug desensitization protocols in patients with drug allergies. Additionally, Dr. Petrov has established inpatient drug desensitization protocols for antibiotics, monoclonal antibodies, aspirin and other medications.

Academic and Research Interests

Dr. Petrov’s research interests focus on conditions that mimic asthma, hypogammaglobulinemia in lung transplant patients, and allergic drug reactions.

Vocal Cord Dysfunction (VCD) is often misdiagnosed and mistreated as asthma, leading to increased asthma medication use and healthcare utilization. While laryngoscopy remains the gold standard for VCD diagnosis, it is often not readily available or practiced by many physicians who may encounter this disorder. Additionally, laryngoscopy may be normal if performed when a patient is asymptomatic.
Dr. Petrov and co-inventers developed the Pittsburgh VCD Index, a simple, valid and easy to use tool for diagnosing VCD. This novel scoring system identified features of VCD that distinguish it from asthma. Symptoms of throat tightness and dysphonia, absence of wheezing, and the presence of odors as a symptom trigger were found to be key features of vocal cord dysfunction that distinguish it from asthma.  Using the appropriate cut-off, the index had a sensitivity and specificity of 83% and 95% respectively, and its utility was confirmed in a population of patients with laryngoscopy-proven VCD. Pittsburgh VCD Index may decrease health care costs, unnecessary medication use and healthcare utilization by making a timely diagnosis of VCD in a patient mistreated for asthma.
