HEMATOLOGICAL AND BIOCHEMICAL PARAMETERS AS PROGNOSTIC INDICATORS FOR SUCCESSFUL REHABILITATION IN CONFISCATED TEMMINCK'S PANGOLINS (SMUTSIA TEMMINCKII)

The establishment of prognostic indicators in wildlife patients aids clinical decision-making and resource allocation. Hematological and plasma biochemical parameters were evaluated as potential prognostic indicators in wild Temminck's pangolins (<i>Smutsia temminckii</i>) rescued from the illegal wildlife trade. In this prospective cohort study, EDTA and lithium heparin blood samples were collected from the ventral coccygeal vein in 41 pangolins within 48 h of confiscation and before veterinary intervention. Receiving operator characteristic curve analysis was performed to assess each parameter as a prognostic indicator for release outcome and, where known, for 28 d survival postadmission. RBC counts, hemoglobin concentration, and Hct were significantly lower in female than in male pangolins. On intake, pangolins that later failed to be released had significantly lower mean corpuscular hemoglobin concentration (MCHC), higher blood urea nitrogen (BUN), and higher creatinine (Crea) values than individuals that were released. Individuals with lower MCHC or higher Crea values were also less likely to achieve 28-d survival. No pangolin with MCHC < 30.2 g/dl, BUN > 84 mg/dl, or Crea > 0.8 mg/dl was successfully rehabilitated. No other hematological or biochemical parameter, including plasma cortisol, total protein, lactate, lactate dehydrogenase, and glucose, showed significant prognostic value. This study suggests that MCHC, BUN, and Crea measured on intake are useful prognostic indicators for rehabilitation success and MCHC and Crea for short-term survival in Temminck's pangolins.
