“…10 Conversely, a study conducted in Turkey by Adem et al showed a different pattern, with 52.6% of cases being male. 11 In our research, slightly over half of the participants (50.78%) did not exhibit any antibodies in the HP panel, while the remaining 49.22% tested positive for HP panel antibodies. This aligns with a study by the National Data Coordinating Centre in India, which found a prevalence rate of 47.3% for HP in India.…”

Identifying the underlying antigen responsible for Hypersensitivity Pneumonitis (HP) in patients poses a significant challenge within the confines of a typical clinical environment. Our primary objective in this study was to investigate the distribution and prevalence of G antibodies among individuals diagnosed with HP, taking into account factors such as age, gender, and geographical location.A retrospective study spanning 5 years (from January 2018 to June 2023) was conducted, involving patients over the age of 18 who had undergone screening for HP. Data collected from 1087 patients was analysed, and the patients were categorized based on age, gender, location, and their antibody status.Out of the total cohort of 1087 patients, 62.47% were female, while 37.53% were male. The overall positivity rate for HP panel testing was determined to be 49.22%. Among the patients subjected to testing, 174 individuals (16.01%) tested positive for at least one specific antibody. Notably, among patients aged 18 to 30 years, Penicillium emerged as the most prevalent (48.28%), closely followed by fumigatus Fumigatus (44.83%). In contrast, for patients aged 31 to 45 years, Pigeon serum feathers exhibited the highest prevalence (39.69%). Moreover, the positivity rates varied across different regions in India.HP can be attributed to an array of agents commonly encountered in both workplace and home settings, encompassing microorganisms, animal and plant proteins, as well as organic and inorganic chemicals. Discerning the causative antigen not only holds immense value for physicians in optimizing patient treatment but also plays a pivotal role in pinpointing the source of exposure. Armed with this knowledge, physicians can provide patients with tailored advice to minimize their exposure risk, potentially leading to disease stabilization or even reversal. In summary, the successful identification of the etiologic antigen emerges as a formidable tool for enhancing the overall quality of patient care.

Introduction The aim of this study was to examine the clinical features of hypersensitivity pneumonia (HP) cases, diagnostic methods, and related conditions in our hospital, which is a reference clinic in Turkey for chest disease. Methods The population of this retrospective cross‐sectional study consists of all hypersensitivity pneumonia patients followed in a tertiary hospital between 2010 and 2019. The data of 78 patients were included in the analysis. Data were grouped by source of exposure (occupational, environmental, and cryptogenic) by examining the files of the patients. Results Occupational risk factors were detected in 29 (37.2%) of the cases, environmental risk factors were found in 24 (30.8%) cases, neither occupational nor environmental risk factors were detected in 25 (32%) cases, and they were evaluated as cryptogenic. The time from the onset of symptoms to diagnosis was 15.8 ± 26.6 months. The time from the onset of symptoms to diagnosis was found to be longer in the group with occupational risk factors compared with the other groups and was statistically significant (0.044). Conclusion HP is a immune‐mediated interstitial lung disease induced by repeated exposure to environmental and occupational antigens. Etiological agent can be detected in HP patients by detailed questioning of occupational and environmental exposure that may be associated with the onset of symptoms in cases with suspected HP.
