RESUMO

Since uric acid to HDL cholesterol ratio (UHR) is proposed as a novel predictor of metabolic and inflammatory disorders, we aimed to study UHR levels in patients with new onset type 2 diabetes mellitus (T2DM) and compare them to those in healthy controls. Patients with new onset T2DM were enrolled and control subjects were volunteers to participate without any established diseases. Laboratory data including UHR, fasting blood glucose (FBG) and glycated hemoglobin (HbA1c) were compared. The mean UHR of the T2DM and control groups was 16±8% and 10±3%, respectively (p<0.001). Moreover, UHR was significantly and positively correlated with HbA1c (r=0.75, p<0.001), FBG (r=0.64, p<0.001), waist circumference (r=0.35, p<0.001), body mass index (r=0.20, p=0.002) and inversely correlated with glomerular filtration rate (r=-0.24, p<0.001). High levels of UHR might be associated with increased mean blood glucose levels for a long time, since UHR was correlated with both FBG and HbA1c in patients with new onset T2DM.

RESUMO

AIM: Chronic hepatitis B is associated with important morbidity and mortality. Inflammation has a pivotal role in hepatic fibrosis of this population. Hemogram-derived inflammatory predictors, such as mean platelet volume (MPV) and platelet to lymphocyte ratio (PLR), are supposed as inflammatory markers in various diseases. We aimed to compare MPV and PLR of the patients with chronic hepatitis B to those of healthy controls and to observe possible correlation between these markers and fibrosis. METHODS: Chronic hepatitis B patients that visited our outpatient gastroenterology clinics were enrolled in the study. Healthy volunteers were enrolled as controls. MPV, PLR and other parameters of the study groups were compared. RESULTS: Median MPV of the mild fibrosis, advanced fibrosis control groups were 8.1 (6.6-13) fL, 8.2 (6.3-14.5) fL and 7.2 (4.6-8.9) fL, respectively (P < 0.001). Median PLR of the mild fibrosis, advanced fibrosis control groups were 99.5 (36-259) %, 119 (61-1547) % and 122 (64-197) %, respectively (P = 0.02). PLR was correlated with the ISHAK score (r = 0.32, P = 0.002). A MPV value greater than 7.52 fL have 80% sensitivity and 56% specificity in determining advanced fibrosis (AUC: 0.68, P = 0.002, 95% confidence interval, 0.58-0.77). CONCLUSION: We think that increased MPV and decreased PLR are characteristics of chronic hepatitis B disease. Moreover, increased MPV could predict advanced fibrosis in this population.

RESUMO

OBJECTIVE: Non-alcoholic fatty liver disease, which is characterized by lipid being deposited into hepatocytes, affects nearly one in three adults globally. Inflammatory markers were suggested to be related with hepatic steatosis. Uric acid to HDL cholesterol ratio is proposed as a novel inflammatory and metabolic marker. We aimed to compare Uric acid to HDL cholesterol ratio levels of patients with Non-alcoholic fatty liver disease to those of healthy controls and find out potential correlations between Uric acid to HDL cholesterol ratio and other inflammatory and metabolic markers of Non-alcoholic fatty liver disease. METHODS: Patients with a diagnosis of Non-alcoholic fatty liver disease who were on clinical follow-up in our institution were enrolled in the study as the Non-alcoholic fatty liver disease group, while healthy volunteers were enrolled as the control group. The Uric acid to HDL cholesterol ratio of the groups was compared and potential correlations were studied between Uric acid to HDL cholesterol ratio and fasting blood glucose, transaminases, serum lipids (triglyceride, LDL-cholesterol), weight, and body mass index. RESULTS: The Uric acid to HDL cholesterol ratio of the Non-alcoholic fatty liver disease (13±5%) group was significantly higher compared to the Uric acid to HDL cholesterol ratio of the control (10±4%) group (p<0.001). Uric acid to HDL cholesterol ratio was significantly and positively correlated with fasting blood glucose, transaminases, triglyceride, body weight, waist circumference, hip circumference, and body mass index. A ROC analysis revealed that a Uric acid to HDL cholesterol ratio level greater than 9.6% has 73% sensitivity and 51% specificity in determining Non-alcoholic fatty liver disease. CONCLUSION: Due to the inexpensive and easy-to-assess nature of Uric acid to HDL cholesterol ratio, we suggest that elevated Uric acid to HDL cholesterol ratio levels be considered a useful tool in diagnosing hepatic steatosis.

RESUMO

OBJECTIVE: The effects of Certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α, on experimentally induced acute pancreatitis (AP) were examined. METHODS: Thirty-six Wistar Albino male rats were randomly divided into four groups. Group I was the control group and no medication administered to this group. Group II was the Certolizumab group, and 100 ml/kg serum physiologic administered into the biliopancreatic duct and a single dose of 10 µg Certolizumab was simultaneously administered intraperitoneally. Acute pancreatitis was induced with a retrograde injection of 3% Na taurocholate into the common biliopancreatic duct in the study (Group III) and treatment (Groups IV) groups. Rats were sacrificed 72 hours later. Serum amylase, lipase, lactate dehydrogenase activities, along with pancreatic histopathology, were examined. RESULTS: Certolizumab treatment significantly decreased serum amylase, lipase, and LDH levels; histopathologically edema, hemorrhage, parenchymal necrosis, fat necrosis, and infiltration scores; immunohistochemically MDA, MPO, TNF-α and Caspase-3 activity. CONCLUSION: The results support the idea that certolizumab might be beneficial for the severity of AP.

RESUMO

OBJECTIVES: To evaluate the effects of certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α (TNF-α), on experimentally induced acute pancreatitis. METHODS: Healthy Wistar Albino male rats (n = 36) were randomly divided into 4 groups (9 rats in each group): group 1, control group; group 2, certolizumab group; group 3, cerulein group; and group 4, cerulein + certolizumab group. Acute edematous pancreatitis was induced via intraperitoneal injection of 80-µg/kg cerulein (20 µg/kg, 4 times at 1-hour intervals) in groups 3 and 4. Certolizumab (10 µg) was intraperitoneally administered in groups 2 and 4. Serum levels of amylase, lipase, TNF-α, and lactate dehydrogenase were evaluated. Histopathology and immunohistochemistry of the pancreatic tissue for assessing the activities of malondialdehyde, myeloperoxidase, TNF-α, and caspase-3 were also performed after 72 hours. RESULTS: Certolizumab treatment significantly decreased the serum levels of amylase, lipase, and lactate dehydrogenase. Histopathological edema, hemorrhage, parenchymal necrosis, and infiltration scores were also decreased, along with a decrease in malondialdehyde, myeloperoxidase, TNF-α, and caspase-3 activities. CONCLUSION: This study suggests that certolizumab is a beneficial treatment mode for reducing the severity of acute pancreatitis.

RESUMO OBJETIVO: Os efeitos de Certolizumab, um anticorpo monoclonal pegilado para o fator de necrose tumoral α, na pancreatite aguda induzida experimentalmente (PA) foram examinados. MÉTODO: Trinta e seis ratos Wistar Albino foram divididos aleatoriamente em quatro grupos. O Grupo I foi considerado o grupo controle e não recebeu medicação; o Grupo II foi o grupo Certolizumab e recebeu 100 ml/kg de soro fisiológico administrado no ducto biliopancreático e dose única de 10 mg Certolizumab administrada por via intraperitoneal simultaneamente. A pancreatite aguda foi induzida com uma injeção retrógrada de uma solução de 3% taurocolato de sódio aplicada no ducto biliopancreático comum nos grupos de estudo (Grupo III) e tratamento (Grupos IV). Os ratos foram sacrificados 72 horas depois. As atividades séricas de amilase, lipase, lactato desidrogenase, juntamente com a histopatologia pancreática, foram examinadas. RESULTADOS: O tratamento com Certolizumab diminuiu significativamente os níveis séricos de amilase, lipase e LDH; edema histopatológico, hemorragia, necrose paranquimatosa, necrose gordurosa e escores de infiltração; atividade imuno-histoquímica de MDA, MPO, TNF-α e Caspase-3. CONCLUSÃO: Estes resultados suportam a ideia de que o Certolizumab pode ser benéfico para a gravidade da PA.

RESUMO

We aimed to evaluate the protective effects of pentoxifylline on alcohol-induced gastric injury, its relation with nitric oxide and prostaglandin synthesis, as well as gastric acidity in rats. Acute gastric mucosal injury was induced by intragastric infusion of 2 ml 98% alcohol. Pentoxifylline was given at 100 mg/kg intraperitoneally. Indomethacin and N(G)-nitro-L arginine were used to inhibit prostaglandin and nitric oxide synthesis, respectively. Macroscopic and microscopic gastric injuries were evaluated. Gastric pH, tissue malondialdehyde levels, oxidized and reduced glutathion (GSSG/GSH) levels, and effects of pentoxifylline on gastric acid output were measured. Pentoxifylline pretreatment significantly reduced macroscopic and microscopic gastric injury. Malondialdehyde level was lower in pentoxifylline treated rats (351.1 +/- 94.1 nmol/g vs 624.3 +/- 234.2 nmol/g). Pentoxifylline has a protective role on alcohol-induced gastric mucosal injury in rats. This effect is not related to synthesis of prostaglandins and changes in gastric acidity but does seem to be related to nitric oxide-mediated pathways. In contrast, pentoxifylline increases gastric acid output significantly.
