All patients included had at least one year of follow up since diagnosis.RESULTS: 179 patients were studied, mean age 60.1 (13.3); 103 were female. The median follow-up was (p25-p75) of 5.9 (3.9-8.6) years. Nineteen patients were excluded due to monitoring loss. Of the 160 patients followed, 87 patients remained alive and 73 had died or had received a lung transplant at the time of the study. The median survival to the date of death or transplantation was 7.0 (4.4-14.5) years. The final study using a proportional hazards model of Cox, which included all potentially influential variables identified in the univariate analysis, showed that the factors independently associated with a reduced survival were age, sex, the percentage of lymphocytes in pulmonary lavage, total lung capacity (TLC) and the CO transfer test (DLCO).CONCLUSION: The median survival of the patients with chronic HP was 7.0 (4.4-14.5) años. The percentage of lymphocites in the pulmonary lavage, the TLC and DLCO were independently associated with survival.
