Abstract
BACKGROUND Leptospirosis is a neglected but widespread zoonotic disease throughout the world. Most mammals are hosts of Leptospira spp., including domestic cats, species in which no consensus has been reached on the clinical presentation or diagnosis of the disease. The study of acute-phase proteins (APPs) and biomarkers of oxidative status would contribute to knowledge about the disease in cats. This report evaluated four APPs: Serum amyloid A-SAA, Haptoglobin-Hp, albumin and Paraoxonase 1-PON1 and the antioxidant response through Total Antioxidant Capacity-TAC, in 32 free-roaming cats. Cats were classified as seroreactive for anti-leptospiral antibodies (group 1, n = 8), infected with Leptospira spp (group 2, n = 5) and leptospires-free cats (group 3, n = 19). RESULTS SAA differences were observed between groups 1 and 2 (p-value = 0.01) and between groups 2 and 3 (p-value = 0.0001). Hp concentration differences were only detected between groups 2 and 3 (p-value = 0.001). Albumin concentrations only differed between groups 1 and 3 (p-value = 0.017) and 2 and 3 (p-value < 0.005). Cats in groups 1 (p-value < 0.005) and 2 (p-value < 0.005) had lower PON1 concentrations than group 3. No statistically significant differences between pairs of groups were detected for TAC concentrations. The principal component analysis (PCA) retained two principal components, (PC1 and PC2), explaining 60.1% of the observed variability of the inflammatory proteins and the antioxidant TAC. CONCLUSIONS Increases in Serum SAA, Hp, and decreases in PON1 activity may indicate an active inflammatory state in infected cats (currently or recently infected).

Abstract
Background Hematopoietic stem cell transplantation (HSCT) is the main treatment for acute radiation sickness, especially after fatal radiation. The determination of HSCT for radiation patients is mainly based on radiation dose, hemogram and bone marrow injury severity. This study aims to explore a better biomarker of acute radiation injury from the perspective of systemic immune response.
Methods C57BL/6J female mice were exposed to total body irradiation (TBI) and partial body irradiation (PBI). Changes in haptoglobin (Hp) level in plasma were shown at different doses and time points after the exposure and treatment with amifostine or bone marrow transplantation. Student’s t-test/two tailed test were used in two groups. To decide the Hp levels as a predictor of the radiation dose in TBI and PBI, multiple linear regression analysis were performed. The ability of biomarkers to identify two groups of different samples was determined by the receiver operating characteristic (ROC) curve. The results were expressed as mean ± standard deviation (SD). Significance was set at P value < 0.05, and P value < 0.01 was set as highly significant. Survival distribution was determined by log-rank test. Results In this study, we found that Hp was elevated dose-dependently in plasma in the early post-irradiation period and decreased on the second day, which can be used as a molecular indicator for early dose assessment. Moreover, we detected the second increase of Hp on the 3rd and 5th days after the lethal irradiation at 10 Gy, which was eliminated by amifostine, a radiation protection drug, while protected mice from death. Most importantly, bone marrow transplantation (BMT) on the 3rd and 5th day after 10 Gy radiation improved the 30-days survival rate, and effectively accelerated the regression of secondary increased Hp level. Conclusions Our study suggests that Hp can be used not only as an early molecule marker of radiation injury, but also as an important indicator of bone marrow transplantation therapy for radiation injury, bringing new scientific discoveries in the diagnosis and treatment of acute radiation injury from the perspective of systemic immunity.

Abstract
Sickle cell anemia is hallmarked by hemolysis, which releases hemoglobin (Hb) into the plasma promoting vaso-occlusive crisis (VOC). Haptoglobin (Hp) clears free Hb and decreases Hb-related pathophysiology in sickle cell anemia. There are two alleles (HP1 and HP2) and three genotypes (HP1-1, HP1-2 and HP2-2) of Hp with different frequencies in different populations. This study involved Hp level and genotype among normal and sickle cell anemia patients with varying severity of VOC. A total of 297 sickle cell anemia patients and 98 healthy controls were selected for the study. The sickle cell anemia patients were categorized as 'mild-phenotype' with no pain episodes and 'severe-phenotype' as having three or more acute pain episodes in the preceding 12 months. The Hp level was significantly lower (p < 0.001) in sickle cell patients anemia than controls; HP1-1 genotype had a higher Hp level compared to HP1-2 and HP2-2 (p < 0.05). Turkey-Kramer multiple comparison tests showed that mild and severe phenotypes have significant differences (p < 0.05) in Hb F%, Hb, platelet count, aspartate aminotransferase (AST), alanine aminotransferase (ALT), direct-bilirubin (Bil-D), total-bilirubin (Bil-T), lactate dehydrogenase (LDH) and Hp level. Pearson correlation revealed that Hp level has a positive (p < 0.05) correlation with Hb F%, Hb, packed cell volume (PCV) and serum urea; in contrast its level is negatively correlated with AST, ALT, Bil-T and LDH. A significantly higher frequency of HP2 allele and HP2-2 genotypes was found in severe phenotypes. In the studied population, it was found that higher HP2 frequency, low Hp level and more hemolysis favors the onset of VOC in sickle cell anemia.
