![]() ![]() Conclusions: Clinical classification of OP is useful to predict clinical course and outcome. Patients with focal OP required no treatment and had no relapse or respiratory-related deaths. Organizing pneumonia was an asymptomatic focal rounded opacity in 10 patients (14%), most often detected on chest radiograph and diagnosed on lung biopsy done for suspicion of lung cancer. Five-year survival was higher in patients with cryptogenic OP (73%) than in secondary OP (44%), and respiratory-related deaths were more frequent in patients with secondary OP. Relapse was infrequent in both of these groups. ![]() ![]() Resolution of symptoms was more frequent in patients with cryptogenic OP than those with secondary OP. Corticosteroids were given at a similar initial dose (prednisone, about 50 mg/d). No difference was found between cryptogenic and secondary OP in type or severity of symptoms, signs, laboratory and pulmonary function tests, or radiologic or pathologic findings. Thirty-seven patients (50%) had cryptogenic OP and 27 patients (36%) had secondary OP. Organizing pneumonia was classified into 3 clinical groups: symptomatic cryptogenic OP symptomatic OP related to underlying hematologic malignant neoplasm, collagen vascular disease, or drugs (secondary OP) and asymptomatic OP presenting as a focal nodule (focal OP). Results: Seventy-four patients had pathologically confirmed OP. Resolution, relapse, and survival were obtained from medical records and a follow-up patient questionnaire. Chest radiographs and pathology specimens were reviewed for this study. Initial features were obtained from medical records. Methods: A retrospective study of patients with OP seen at the Mayo Clinic, Rochester, Minn, from January 1, 1984, through June 30, 1994, was conducted. The goals of this study are to describe the clinical course and outcomes in patients with 3 clinical variants of OP. Clinicians frequently encounter pathology reports of OP in patients with no underlying condition (cryptogenic OP, also known as BOOP or bronchiolitis obliterans OP) or in association with drugs or nonpulmonary disease. If your dog is sick, vets say you should consider having your dog tested with a PCR test to help determine the cause.Ĭontact your local vet or follow the Oregon Veterinary Medical Association or American Veterinary Medical Association for updates and tips on how to keep your dog safe.Background: Organizing pneumonia (OP) is a non-specific response to many types of lung injury. “Just like with other respiratory pathogens, the more contacts your dog has, the greater the risk of encountering a dog that’s infectious,” the vet association said.įor dogs attending events or situations with a group of other dogs, vets suggested making sure all dogs are up-to-date on vaccines, conducting a health check 12 to 24 hours before the event and having a vet on-site to check dogs’ health issues. If dog owners are concerned, vets recommend reducing contact with large numbers of unknown dogs, keeping pets away from others that look sick and avoiding communal water bowls. The Oregon Veterinary Medical Association encourages dog owners to speak to a veterinarian about what vaccines may be appropriate for their dog, including ones that target canine influenza, Bordetella and parainfluenza. Oregon’s Agriculture Department recommend pet owners consult a veterinarian, since the state agency said there is no “one-size-fits-all recommendation” for a potentially broad range of respiratory diseases. What should you do and where can you get help? Cases more commonly occur in animals housed in settings such as shelters, boarding or training facilities rather than in animals housed in private homes, especially those with limited access to other dogs, the association explained. Periodic outbreaks of respiratory diseases occur in dogs and cases can be serious, the association said. ![]() The Oregon Veterinary Medical Association suggested “caution rather than worry” on Nov. Williams cautioned dog owners to not panic and told them to make sure pets are up-to-date on vaccinations. Kurt Williams, director of the Oregon Veterinary Diagnostic Laboratory at Oregon State University, is quoted as telling the Associated Press that “dogs have died,” but said that it’s hard to count how many died from a severe form of the infection without any clear way to define the disease or test for it yet. Ryan Scholz says the "number of deaths have been a very small percentage of total cases." The department notes that state veterinarian Dr. Oregon’s Department of Agriculture told TIME it is receiving "reports of illness and some deaths" although the desk is not actively tracking case outcomes. ![]()
