Abstract
BACKGROUND There is a limited number of studies comparing the levels of inflammation in adolescent patients with anorexia nervosa (AN) and healthy controls based on complete blood count and platelet parameters. METHODS This study is a retrospective cross-sectional analysis of 53 drug-naive patients with AN and 53 healthy controls. RESULTS Significant differences were observed for WBC (white blood cell), neutrophil, MCV (mean corpuscular volume), MCH (mean corpuscular haemoglobin) and neutrophils/lymphocytes ratio (NLR) between the study groups. Patients with AN had lower WBC, neutrophiles and NLR values. But there was no difference between the groups in terms of inflammation-related platelet parameters. A strong positive correlation between BMI (body mass index) and PLT (platelet), PCT (plateletcrit) was determined in the patient group (r = 0.454, p = 0.001; r = 0.386, p = 0.007). Inflammation-related parameters may increase as BMI increases with nutrition and weight restoration. CONCLUSIONS The present study provides further evidence for level of inflammation in these patients does not increase during the acute period, unlike other mental diseases.

Thrombocytopenia and PT-INR in patients with anorexia nervosa and severe liver dysfunction. Biopsychosoc Med 2023; 17:9. [PMID: 36890598 PMCID: PMC9996900 DOI: 10.1186/s13030-023-00269-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 02/28/2023] [Indexed: 03/10/2023] Open
Abstract
BACKGROUND We previously reported a case that led us to hypothesize that decreased production of thrombopoietin (TPO) leads to thrombocytopenia in patients with anorexia nervosa (AN) with severe liver dysfunction and that prolonged prothrombin time-international normalized ratio (PT-INR) predicts thrombocytopenia in such cases. To validate this hypothesis, we report another case in which TPO levels were measured. In addition, we examined the association between prolonged PT-INR and thrombocytopenia in such patients. MAIN BODY Similar to the previously reported patient, a patient with AN with severe liver dysfunction showed that TPO levels increased after improvements in liver enzyme levels and PT-INR, followed by recovery of platelet count. In addition, a retrospective study was also conducted to review patients with AN whose liver enzyme levels were > 3 × the upper limit of normal (aspartate aminotransferase > 120 U/L or alanine aminotransferase > 135 U/L). The study included 58 patients and showed a correlation coefficient of -0.486 (95% confidence interval [CI], -0.661 to -0.260; P < 0.001) between maximum PT-INR and minimum platelet count. These patients showed higher PT-INR (β, 0.07; 95% CI, 0.02 to 0.13; P = 0.005) and lower platelet count (β, -5.49; 95% CI, -7.47 to -3.52; P < 0.001) than the 58 matched control patients without severe liver dysfunction, even after adjusting for body mass index. CONCLUSIONS In patients with AN with severe liver dysfunction, prolongation of PT-INR could predict thrombocytopenia, which may be mediated by decreased TPO production due to decreased hepatic synthetic function.

Polymorphisms in the ovine GP5 gene associated with blood physiological indices. Anim Biotechnol 2021:1-11.

Abstract
This study aimed to analyze the effects of polymorphisms in GP5 on blood physiological indices of 1065 sheep. The coefficients of variation of the red blood cell count (RBC), hemoglobin concentration (HGB), mean platelet volume (MPV), mean erythrocyte hemoglobin content (MCH), and red blood cell distribution-coefficient of variation (RDW-CV) were greater than 10%, and there was a very significant correlation between the main indices such as RBC, white blood cell, and platelet count (PLT) and most other indices (p < 0.01). qRT-PCR showed that GP5 was expressed in the heart, liver, spleen, lung, kidney, rumen, duodenum, muscle, tail fat, and lymph tissue, with significantly higher expression in the lymph. Subsequently, we detected single nucleotide polymorphisms (SNPs) in GP5 from group, which identified synonymous mutation g.657 T > C in the first exon of GP5. Association analysis showed significant correlations between the SNP and the physiological traits (p < 0.05), in which the RBC, neutrophilic granulocyte (NEUT) and RDW-CV values in sheep with the TC genotype and TT genotype were markedly lower than those in the CC genotype (p < 0.05). Thus, GP5 polymorphisms could be candidate biomarkers to screen blood physiological indices.

"Case series: ischemic stroke associated with dehydration and arteriosclerosis in individuals with severe anorexia nervosa". J Eat Disord 2021; 9:39.

Abstract
BACKGROUND Numerous reports have indicated that patients with anorexia nervosa (AN) are at a relatively high risk of developing vascular diseases, including cardiovascular events and venous thromboembolism. However, there have been no previous reports of the development of ischemic stroke during refeeding therapy in patients with severe AN. This report is aimed at reporting the characteristics of an ischemic stroke in patients with AN. CASE PRESENTATIONS Our study included 29 admissions by independent 19 female patients cases (19 patients), who received thorough medical, neurological, and psychiatric examinations. Two patients were diagnosed as having developed ischemic stroke; the first patient showed multiple infarctions in the brain, while the second showed symptomatic focal infarction. Our findings suggest that dehydration and arteriosclerosis, in association with severe malnutrition, could predispose to the development of ischemic stroke in patients with severe AN. CONCLUSIONS Development of ischemic stroke in patients with AN might be overlooked. Watching out for neurological signs would help in early diagnosis of ischemic stroke in patients with AN during refeeding. Specific etiology could induce ischemic stroke in patients with AN even if they have no common risk factors of ischemia.
