Correlation of Serum Asprosin Levels With Normalized Protein Catabolic Rate in Patients Receiving Peritoneal Dialysis Treatment.
Background Peritoneal dialysis patients are malnourished due to loss of protein in the dialysate and inadequate dialysis, although they take additional calories every day during treatment. Many parameters are used to assess nutritional status, with normalized protein catabolic rate (nPCR) being one of the most common. Asprosin, a novel adipokine secreted by adipose tissue, peaks during fasting and induces hepatic glucose release through the activation of the G-protein- cAMP-PKA pathway, which has been indicated to have a curative effect on chronic inflammation. In this study, we aimed to investigate the relationship between asprosin levels and nutritional parameters in patients receiving peritoneal dialysis treatment as well as to investigate the applicability of more practical tests. Methodology A total of 70 peritoneal dialysis patients, 35 female (59%) and 24 male (41%), were included in the study. The mean age of the patients was 53 +/- 14 years (range = 18-80 years), and the median peritoneal dialysis duration was 31.5 months (range = 20-56.2 months). The most common etiologic cause was hypertension (37%). Patients over 18 years of age who had been receiving peritoneal dialysis treatment for at least 24 months were included in the study. The correlation between patients' nPCR levels and serum asprosin, body mass index, and lipids was evaluated. Results The correlation between the level of nPCR and the serum asprosin level, body mass index, and lipids was evaluated. Patients with nPCR <0.815 were considered malnourished, and factors affecting malnutrition were determined by univariate analysis. Among the factors affecting malnutrition according to univariate analysis, those with p-value <0.05 were analyzed by multivariate analysis. Low asprosin level was one of the independent factors affecting malnutrition in patients (Exp(B) = 0.944, 95% confidence interval (CI) = 0.896-0.994). Other independent factors affecting malnutrition were Kt/V (Exp(B) = 0.018, 95% CI = 0.001-0.550) and residual renal function (Exp(B) = -0.004, 95% CI = 0.993-0.999). Conclusions There is a need for more accessible tests and reliable parameters to evaluate dialysis and nutritional deficiency in peritoneal dialysis patients. One possible hormone that could serve as a guide is asprosin
Central Nervous System Infections in the Intensive Care Units and Risk Factors for Mortality; Retrospective Study
Acute Motor and Sensory Axonal Neuropathy (AMSAN) Associated with COVID-19 Infection; A Case Report
Myalgia and headache are relatively common in COVID-19 disease, but a serious neurological disease is uncommon. In this case, we describe the symptoms and clinic of AMSAN, a rare variant of Guillain Barre syndrome (GBS) due to COVID 19. We presented a case of AMSAN, a rare variant of GBS, in a 46-year-old male patient with poor overall condition that did not recover after COVID-19 disease, loss of strength and decreased sensation in distal limbs. electromyography-nerve conduction study findings were suggestive acute motor and sensory axonal neuropathy. Cerebrospinal fluid analysis was elevated protein with a normal white blood cell count. The clinical diagnosis of AMSAN supported by results of diagnostic testing such as cerebrospinal fluid and electromyography-nerve conduction study

Does serum butyrylcholinesterase level determine the severity and mortality of COVID-19 pneumonia?: Prospective study
Copyright © 2022 Sipahioglu, Esmaoglu, Kiris, Dursun, Kuzuguden, Cavus and Artan.Background: The WHO emphasized the importance of knowing the risk factors for the severity of the disease in the COVID-19 pandemic. Our aim in this study was to determine the relationship between serum Butyrylcholinesterase (BChE) level, which is rapidly affected by inflammation, and the severity of COVID-19 pneumonia and mortality. Methods: Patients diagnosed with COVID-19 pneumonia between March and May 2021 were included in the study. The patients were divided into two groups as severe and mild to moderate pneumonia according to the WHO's guidelines. Serum BChE levels were studied by ELISA method from the blood samples taken from the patients on the day of hospitalization. The severity of the disease and other factors affecting hospital mortality were also evaluated. Results: 147 patients with COVID-19 pneumonia were included in this study. Of these patients, 58% had severe pneumonia and 42% had mild to moderate pneumonia. The BChE level was median 13 (IQR: 11.2–21.5)ng/ml in patients with severe COVID-19 pneumonia and median 20 (IQR: 10–35.7)ng/ml in patients with mild to moderate pneumonia (p: 0.001). Hospital with mortality rate was higher in patients with low BChE levels. However, statistically, BChE hasn't associated mortality in COVID-19 pneumonia [OR 1.002 (0.957–1.049) p: 0.490]. CRP, procalcitonin, lactate, and D-dimer levels were associated mortality in COVID-19 pneumonia. Conclusion: Being not statistically significant, the mortality rate was higher in patients with low BChE levels. BChE level is an important marker in determining the severity of COVID-19 pneumonia. Early prediction of the severity of COVID-19 pneumonia will enable early planning of the treatment process
Importance of Asprosin for Changes of M. Rectus Femoris Area during the Acute Phase of Medical Critical Illness: A Prospective Observational Study
Asprosin, a new adipokine, is secreted by subcutaneous white adipose tissue and causes rapid glucose release. The skeletal muscle mass gradually diminishes with aging. The combination of decreased skeletal muscle mass and critical illness may cause poor clinical outcomes in critically ill older adults. To determine the relationship between the serum asprosin level, fat-free mass, and nutritional status of critically ill older adult patients, critically ill patients over the age of 65 receiving enteral nutrition via feeding tube were included in the study. The patients’ cross-sectional area of the rectus femoris (RF) of the lower extremity quadriceps muscle was evaluated by serial measurements. The mean age of the patients was 72 ± 6 years. The median (IQR) serum asprosin level was 31.8 (27.4–38.1) ng/mL on the first study day and 26.1 (23.4–32.3) ng/mL on the fourth study day. Serum asprosin level was high in 96% of the patients on the first day, and it was high in 74% on the fourth day after initiation of enteral feeding. The patients achieved 65.9 ± 34.1% of the daily energy requirement for four study days. A significant moderate correlation between delta serum asprosin level and delta RF was found (Rho = −0.369, p = 0.013). In critically ill older adult patients, a significant negative correlation was determined between serum asprosin level with energy adequacy and lean muscle mass
GAS6/sAXL ratio correlates with National Institutes of Health Stroke Scale (NIHSS) and infarction size in patients with acute ischemic stroke
Background & Objective: Ischemic stroke is the leading cause of death and long-term disability worldwide. In patients with ischemic stroke, both cell loss and inflammation are observed. GAS6/sAXL signaling is effective in both inflammation and clearance of dead/dying cells. This study investigated the GAS6/sAXL pathway and its role in patients with acute stroke. Specifically, we evaluated whether GAS6/sAXL was associated with stroke severity and infarct volume. Methods: This study involved 53 patients with acute ischemic stroke (AIS) and 49 healthy controls. GAS6 and sAXL proteins were collected in the first 24 hours in the acute stroke. NIHSS scores, GCS, and demographic data of the patients at the time of admission to the hospital were recorded. The infarct area was calculated using cranial magnetic resonance imaging. Results: Mean age of the patients was 64±12 years, 60% were female. HDL was lower in AIS group (40.5±13.01 mg/dl) than in the control group (55.4±14.9 mg/ dl) (p<0.05). The GAS6 levels of patients with ischemic stroke (30.58 [1.58-162.33] ng/dL) were significantly lower than the control group (83.33 [10.71-181.96] ng/dL) (p < 0.001). There was a significant difference in the GAS6/sAXL ratio between the AIS (8.60 [0.55-48] ng/mL) and control groups (14.78 [1.82-53.71] ng/mL) (p < 0.001). The serum GAS6 level and MR infarct area was positively correlated (r = 0.381 p = 0.005). The GAS6/sAXL ratio was positively correlated with the NIHSS and infarct area (p = 0.004). The GAS6/sAXL ratio and GCS showed a negative correlation (p = 0.001). Conclusion: Plasma GAS6 levels were positively correlated with infarct size, and the GAS6/sAXL ratio was positively correlated with the NIHSS score and infarct area in patients with AIS. Plasma GAS levels and GAS6/sAXL ratio can be used as an indicator of severity of AIS

Outcomes of High-Dose Vitamin C Therapy on Patients Diagnosed with COVID-19 Associated ARDS in Intensive Care Units: Multi-Center Retrospective Study
Background and Aim: The new type of Severe Acute Respiratory Syndrome Coronavirus 2 (Coronavirus 2019-COVID-19) infection is the largest pandemic in the last decade. Acute respiratory distress syndrome is the complication with the highest mortality rate of this infection and there is no adequate treatment with proven efficacy to reduce mortality. This multi-center, retrospective study aimed to determine the effect of high-dose vitamin C on survival and other endpoints in invasively ventilated ARDS patients.Methods: This multi-center, observational retrospective cohort study was performed at five ICU centers between March 2020 and July 2020. Patients with ARDS due to COVID-19 who required IMV were included. High-dose vitamin C group was defined as patients who were treated with vitamin C over 200 mg/kg for four days. Patients who were not given vitamin C treatment were defined as the control group by using propensity score match analysis, as well. The groups were compared about the effects of high-dose vitamin C treatment on ICU mortality.Result: A total of 86 patients with a mean age of 67.85 +/- 10.38 were included in the study. 72.1% of the patients were male. Forty-two (49%) patients were in the high dose vitamin C group, and 44 (51%) were in the control group. The mean PaO2/FiO2 at the time of admission to the ICU was 128.27 +/- 58.69 mmHg (133.63 +/- 56.51 mmHg in the control group, 122.36 +/- 61.18 mmHg in the study group, p=0.389). The mortality rate of high dose vitamin C group was lower than the control group (73.8% vs. 90.9%, p = 0.037,respectively).Conclusion: As an adjunctive therapy in invasively ventilated patients with COVID-19-associated ARDS, high doses of vitamin C may reduce mortality and development of organ damage. Prospective, randomized controlled studies with larger numbers of patients are needed to confirm these findings
