BACKGROUND: SARS-CoV-2 is the cause of a pandemic with high mortality. In the present study, the effects of the lipase/lymphocyte ratio on mortality were investigated in cases diagnosed with Covid-19 and acute pancreatitis. METHODS: A total of 21 patients who were diagnosed with Covid-19 and acute pancreatitis, 34 patients who were not diagnosed with COVID-19 but diagnosed with acute pancreatitis, and 55 healthy control groups were divided into 3 groups and included in the study retrospectively. The patients who had positive RT-PCR (real-time polymerized chain reaction) test results were included in the study. Complete blood count and biochemical values of the patients were compared with those of the control group. RESULTS: When the data of the cases diagnosed with COVID-19 and acute pancreatitis were examined retrospectively, the amylase, lipase, lipase/lymphocyte ratio, and D-dimer levels were found to be signifi cantly higher than in the control group (p < 0.01). In the ROC analysis, the amylase, lipase, and lipase/lymphocyte ratio had a high AUC (area under the curve) value (0.993 / 0.949 / 0.978, respectively). CONCLUSION: The lipase/lymphocyte ratio can be used in cases diagnosed with Covid-19 and acute pancreatitis to predict mortality (Tab.

The aim of present study was to investigate the dynamic thiol/disulfide homeostasis as oxidative stress marker in diabetic ketoacidosis (DKA). Materials and methods:A total of 77 participants consisting of 32 patients with DKA and 45 healthy volunteers were included in the study. Thiol/disulfide homeostasis (TDH) [total thiol-native thiol/disulfide changes] were measured in both groups (patient group and control group) using a brand new method developed by Erel and Neselioglu. Half of the difference between total thiol and native thiol concentrations gives the amount of disulfide bond. Results: Total thiol, native thiol, and disulfide levels in blood were found to be low. The levels of total thiol (P < 0.001) and native thiol (P < 0.001 ) were significantly lower in patients with DKA than in the control group. At the same time, the level of disulfide was nonsignificantly lower in the patient group than the control group (P = 0.388). The level of IMA was higher in the patient group than in the control group (P < 0.001). Conclusion:The total thiol, native thiol, and disulfide levels in DKA decrease in favor of oxidative stress.

Bu çalışmanın amacı acil servise karbon monoksit zehirlenmesi nedeniyle başvuran hastalarda oksidatif stres markerlarından olan thiol/disülfit homeostazis parametreleri ile Nötrofil-Lenfosit (NLO) beraber kullanımının tanı açısından yararlı olup olmadığını araştırmaktır. Materyal ve Metot: Çalışma 01.01.2014 ile 01.03.2015 tarihleri arasında acil servise başvuran ve çalışmaya alınan 45 hasta ve kontrol grubu olarak belirlenen 40 sağlıklı kişi ile prospektif olarak yapıldı. Erel ve Neşelioğlu tarafından yeni geliştirilen bir metot ile oksidatif stres markerı olan thiol/disülfit homeostazis parametreleri (Thiol, disülfit, disülfit/native thiol, disülfit/total thiol, native thiol/total thiol) ile NLO hasta ve kontrol grubunda çalışıldı. Bulgular: Karbonmonoksit zehirlenmesi olanlarda kontrol grubuna göre, NT, TT, index 3 ve NLO oranlarında anlamlı farklılık tespit edildi. NT, TT ve index 3 hasta grubunda daha düşük, NLO ortalama değerleri daha yüksek bulundu (sırasıyla p =0,005; < 0,001; < 0,032 ve < 0,001). Sonuç: NLO ile thiol/disülfit homeostasis parametrelerinin karbonmonoksit zehirlenmesi tanısında beraber kullanılması bu hastalarda tanının konulması açısından faydalıdır.

BACKGROUND: Acute pancreatitis is a common disease seen in emergency departments because of abdominal pain. The present study aims to evaluate the relation between measurements of thiol-disulfide parameters in patients diagnosed with acute pancreatitis and other blood parameters. METHODS: A total of 56 (56%) patients, who were admitted to the emergency department, and 44 (44%) healthy volunteers participated in this study. A total of 100 samples were taken from the participants. Detailed blood samples were taken from the patients at the time of arrival at the hospital. The thiol-disulfide level in serum was examined using a brand new method that was developed by Erel and Neşelioğlu in the venous blood samples of the patients who were diagnosed with acute pancreatitis during the admission. The data were evaluated in the computer medium. RESULTS: Gallstones were defined as the etiology of AP in 41 patients (73.2%); in one patient, hypertriglyceridemia (1.7%); in four patients, alcohol use (7.1%), and idiopathic 10 patients (17.8%). While the blood thiol levels were low, the disulfide levels were high at a significant level. No statistically significant relations were detected between the amylase, lipase, neutrophil lymphocyte ratio (NLR), which are other blood parameters, and thiol-disulfide balance parameters. CONCLUSION: The disruption of the thiol-disulfide balance may play a role in the pathogenesis of acute pancreatitis. In acute pancreatitis, since the thiol level is decreased in the blood, administration of the complementary therapies for this thiol deficiency may contribute to the treatment of the disease.
