P92 C REACTIVE PROTEIN AS A PREDICTIVE INDICATOR OF TREATMENT AND DISEASE PROGRESSION IN PATIENTS WITH SARCOIDOSIS: A RETROSPECTIVE OBSERVATIONAL

patient had polyclonal hypogammaglobulinaemia, but levels were not measured in 11/42 (26%) with potential features of CVID. Conclusion Our study identified a cohort of patients with a diag-nosis of sarcoidosis and features associated with CVID. We found that immunoglobulins were not being routinely measured during the work-up of patients with sarcoidosis as recommended by the Map of Medicine. Recent review of 28 local CVID patients identified two who were initially misdiagnosed with sarcoidosis. In one case this misdiagnosis persisted for 8 years. Granulomatous CVID is uncommon, but respiratory physicians should ensure that their routine work-up for sarcoidosis excludes this treatable condition
