About Us

Hypersensitivity pneumonitis (HP) is an inflammatory and/or fibrotic interstitial lung disease arising in susceptible individuals after inhaled exposure to an inciting antigen. Identifying the cause of HP is an important part of diagnosis and management. There are many potential exposures associated with HP, with new ones described each year.

hpLung.com is a free, online repository of potential causes of HP, as identified within the published medical literature, excluding conference abstracts. Currently, our database is up-to-date with references from a comprehensive literature review from January 1, 2002 to December 31, 2019. Data extraction from older citations is still ongoing. This is a living resource that will continue to be manually updated on a regular basis as new exposures associated with HP are described.

If you are aware of a reference describing a potential cause of HP that is not included here, please send an email with the reference to contact@hplung.com.

hpLung.com was created by Dr. Jesse Lu, Dr. Hayley Barnes and Dr. Kerri Johannson in 2018.
