Clinical, radiological and pathological features of 12 Irish setters with canine leucocyte adhesion deficiency.
The clinical, radiological and pathological findings in 12 dogs with canine leucocyte adhesion deficiency (CLAD) from six litters are described. All the dogs were younger than 15 weeks at admission, all had been febrile and 11 had been treated with antibiotics. Seven had been treated for omphalophlebitis. At admission, all had gingivitis, lymph node enlargement and profound neutrophilia. Ten dogs were radiographed and showed various skeletal lesions compatible with metaphyseal osteopathy, craniomandibular osteopathy and osteomyelitis. Four dogs had clinical signs of respiratory distress and seven exhibited a mild interstitial pneumonia at necropsy. Six dogs had skin wounds, with strikingly few neutrophils seen on stained sections. All dogs were euthanased before six months of age due to severe and incurable infections. The clinical signs, radiological features and haematology were strongly suggestive of CLAD. The diagnosis was confirmed by granulocyte function tests and flow cytometry, which revealed impaired adhesion, impaired C3b-mediated phagocytosis and absence of adhesion proteins CD11b/CD18.
