Measurement of T-cell receptor excision circles (TREC) in neonates has allowed for population-based screening of severe combined immunodeficiency and other disorders associated with T-cell lymphopenia. In addition to primary T-cell lymphopenic disorders, secondary causes of T-cell lymphopenia can be diagnosed with TREC analysis. We discuss the diagnostic evaluation of a patient with normal TREC analysis at birth that became abnormal after cardiac surgery. TREC analysis was performed by the Florida State Laboratory. Diagnostic evaluation and treatment were performed at All Children's Hospital, St Petersburg, Florida. We identified a 38-day-old female patient with thoracic duct injury, which caused chylothorax and chylous ascites diagnosed after an abnormal newborn screen. Chylothorax was secondary to thoracic duct injury after cardiac surgery and led to severe lymphopenia and hypogammaglobulinemia. Thoracic duct ligation led to improved lymphocyte counts and normalization of immunoglobulin levels. Secondary causes of lymphopenia are detected with TREC assay that lead to abnormal newborn screen results. Many secondary causes of lymphopenia can be acquired with normal initial newborn screens that become abnormal over time.

A 7-month-old Cavalier King Charles Spaniel female was referred due to a chronic cough refractory to antibiotic treatments. Laboratory findings showed leukocytosis, increased serum C-reactive protein, hypogammaglobulinemia, and decreased total serum immunoglobulin G concentration. Thoracic radiographs showed a mild bronchial pattern. Cytology of the bronchoalveolar lavage fluid revealed a septic inflammation. Bordetella bronchiseptica, Mycoplasma spp., and Pneumocystis carinii were identified by polymerase chain reaction testing, and Klebsiella pneumonia was cultured from the bronchoalveolar lavage fluid. Moreover, Escherichia coli was also cultured from urine. Pneumocystis spp. identification was done by sequencing of genetic amplicons. The dog died due to cardiopulmonary arrest secondary to a spontaneous pneumothorax on the day following the procedure. This report documents the detection of Pneumocystis carinii f. sp. canis in a suspected immunocompromised Cavalier King Charles Spaniel with concurrent pulmonary and urinary tract infections involving four different pathogens, and highlights the importance of the use of polymerase chain reaction testing to detect canine Pneumocystis spp. in cases with negative bronchoalveolar lavage cytology.
