[Abstract]:Objective to compare the clinical features and prognosis of cryptogenic pneumonia with that secondary to connective tissue disease (OP). Methods A retrospective study was conducted in 37 patients with OP confirmed by pathology from February 2006 to January 2012 in the affiliated Chinese University Hospital of Southeast University. The pulmonary function was examined according to the clinical symptoms. The results of immunological examination and high resolution CT (HRCT) scan of chest, combined with typical histopathological manifestations of OP, were reviewed by experienced doctors in respiratory department, rheumatology department, radiology department and pathologist, and 5 cases of pathogeny were excluded as drugs. Thirty-two patients with OP caused by radiation therapy or infection were included in the study and were divided into two groups: (COP) group (n = 14) and CTD-OP group (n = 18). Patients in both groups were treated with glucocorticoid for 3-12 months and followed up for 18 months. The clinical symptoms, pulmonary function, arterial blood gas, imaging features and prognosis were compared between the two groups. Results there was no significant difference in age, incidence of dyspnea, oxygenation index (PaO2/FiO2) and C-reactive protein (CRP) between the two groups (P0.05). The percentage of women, the positive rate of rheumatoid factor (RF) and the positive rate of anti-nuclear antibody (ANA) in CTD-OP group were higher than those in COP group (P0.05). Forced expiratory volume (FEV1%), forced vital capacity (FVC%), total lung volume (TLC%), and residual volume (RV%) in the first second of the two groups were compared. Forced expiratory volume / forced vital capacity (FEV1/FVC), carbon monoxide diffusion as a percentage of predicted value (DLCO%), arterial partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), (P (A-a) O 2) there was no significant difference before and after treatment (P0.05). Intragroup comparison showed that there were significant differences in FEV1%,FVC%,TLC%,RV%,FEV1/FVC,DLCO%,PaO2,P (A-a) O _ 2 between the two groups before and after treatment (P0.05). There was no significant difference between the two groups (P0.05). The total effective rate of the two groups was 93.8% (30 / 32) after hormone therapy, and the difference between the two groups was statistically significant (u-2.080). The recovery rate in COP group (50.0%) was higher than that in CTD-OP group (16.7%), and the recurrence rate (7.1%) was lower than that in CTD-OP group (38.9%). The difference was statistically significant (蠂 2 4.17 4.20 P 0.04 0. 03). Conclusion the early clinical symptoms of patients with COP and CTD-OP are similar, showing mild and moderate restrictive ventilation dysfunction and abnormal diffusion function, and mild hypoxemia. Hormone therapy in the early stage of the high effective rate, in the latter stage of follow-up found that the recurrence rate of CTD-OP patients than COP patients, the recovery rate is low, so OP patients need to be followed up regularly.
