Previously, he was Section Chief of Allergy/Immunology in the Department of Medicine at Thomas Jefferson University in Philadelphia, Pa., Division Chief of Allergy/Immunology and Co-Director of the Allergy and Asthma Center at Hahnemann University.  Dr. Lang also teaches evidence based medicine at the Cleveland Clinic Lerner College of Medicine.

Dr. Lang has carried out a number of research projects. He has directed studies of the epidemiology of urban asthma, anaphylaxis and urticaria/angioedema. 

The asthma studies carried out revealed that in Philadelphia, showed an alarming rise in annual rates of asthma mortality that had occurred--disproportionately affected African Americans, Hispanic Americans, and residents of poverty areas--and highlighted a dramatic underuse of inhaled steroid medications. He is continuing studies of asthma epidemiology in Ohio.

He was principle investigator of a project investigating risk factors for anaphylactoid reaction to contrast media. This study showed that asthma, cardiovascular disease and beta blocker use were statistically significant risk factors for moderate-to-severe anaphylactoid reaction from intravenous contrast infusion. Females were also found to be at significantly elevated risk for anaphylactoid and severe anaphylactoid reaction from contrast material.  

Dr. Lang has been active in national and regional medical organizations, and he has published numerous articles, chapters, and abstracts. Dr. Lang’s professional affiliations include fellowships in the American Academy of Allergy, Asthma, and Immunology; the American College of Allergy, Asthma, and Immunology; and the American College of Physicians.  He has also served as president of the Pennsylvania Allergy and Asthma Association.

Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers’ discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.
