Serum Copeptin Levels Predict the Return of Spontaneous Circulation and the Short-Term Prognosis of Patients with Out-of-Hospital Cardiac Arrest: A Randomized Control Study.

INTRODUCTION: Early and accurate prediction of survival to hospital discharge following resuscitation after cardiac arrest (CA) is a major challenge. Biomarkers can be used for early and accurate prediction of survival and prognosis following resuscitation after CA, but none of those identified so far are sufficient by themselves. HYPOTHESIS/PROBLEM: The goal of this study was to investigate the predictive power of the serum copeptin level for determining the return of spontaneous circulation (ROSC) and prognosis of patients with non-traumatic out-of-hospital cardiac arrest (OHCA) who underwent cardiopulmonary resuscitation (CPR). METHODS: A total of 76 consecutive consenting adult patients who were diagnosed as non-traumatic OHCA and 63 age- and sex-matched healthy controls were enrolled. The patients were divided into two groups based on whether or not they had ROSC. The ROSC group was divided into two sub-groups according to whether death occurred within 24 hours or after 24 hours following ROSC. Serum copeptin, high-sensitivity cardiac troponin (hs-cTnI), creatine kinase-muscle/brain (CK-MB), glucose, and blood gas values were compared between the groups. RESULTS: Serum copeptin levels were significantly higher in the patient group than control group (P <.001). Receiving operator characteristic analysis revealed a cut-off copeptin level of 27.29pmol/L, with 98.7% sensitivity and 100.0% specificity, for distinguishing patients from controls. Serum copeptin levels were significantly lower in the ROSC group than non-ROSC group (P = .018). Additionally, the mean serum hs-cTnI level was significantly higher in the ROSC group than non-ROSC group (P = .032). However, there were no significant differences in the mean serum glucose level and CK-MB levels or arterial blood gas levels between the ROSC and non-ROSC groups (all P >.05).Ten (38.5%) of the patients died within the first 24 hours after ROSC, whereas 16 (61.5%) survived longer than 24 hours. Serum copeptin levels were significantly lower in patients who survived longer than 24 hours compared with those who died within the first 24 hours. Moreover, the mean CPR duration was significantly lower in patients surviving more than 24 hours compared with less than 24 hours. CONCLUSION: The serum copeptin level may serve as a guide in diagnostic decision making to predict ROSC in patients undergoing CPR and determining the short-term prognosis of patients with ROSC.

The role of high sensitive C-reactive protein and histopathological evaluation in chronic gastritis patients with or without Helicobacter pylori infection.

PURPOSE: To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. METHODS: A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in the study. On endoscopy, five gastric biopsies were taken according to Modified Sydney protocol, which were stained with hematoxylin & eosin and Giemsa. RESULTS: HP infection was found in 28.6% of patients, being significantly more common in specimens with acute and chronic inflammatory activity. Mucosal atrophy, intestinal metaplasia, and dysplasia were found in 20.2%, 18.8% and 2.7% of biopsy specimens. Mean hs-CRP was 1.9±1.6 mg/dl for males and 2.2±1.9 mg/dl for females. hs-CRP average were significantly higher in patients with severe acute inflammation (p:0.049), in patients with severe chronic inflammation (p:0.015) and in those with HP (p: 0.001) . The severity of HP infection increased significantly with the increased degree of acute inflammation, chronic inflammation and hs-CRP level (p=0.001 for both). CONCLUSION: Serum hs-CRP level increases in patients with chronic gastritis, it could be an indicator of severity of acute or chronic mucosal inflammation, and presence of HP infection. Therefore, hs-CRP may aid the diagnosis of chronic gastritis, but it is not associated with pre-cancerous lesions.

Frequency of fetal macrosomia and the associated risk factors in pregnancies without gestational diabetes mellitus.

INTRODUCTION: There has been an increased incidence of macrosomic newborns in the world and most of the macrosomic newborns are born from non-GDM pregnant women. The objective of this study was to determine the frequency and the associated risk factors of fetal macrosomia in non-GDM pregnant women. METHODS: A total 4246 consequtive pregnant women who had no GDM was included the study population. Data was collected from hospital database of Balikesir State Hospital between January 2014 and January 2015. Statistical analysis was carried out using the independent samples t-test and chi-squared test. Logistic regression analysis was used to determine the relationships between associated risk factors and the presence of fetal macrosomia. In this analysis, fetal macrosomia was taken as the dependent variable and associated risk factors were taken as independent variables. Results are shown as odds ratios (ORs) (95% CI) in the logistic regression analysis. RESULTS: 366 of the 4246 pregnant women were diagnosed with fetal macrosomia (8.6%). Compared the control women, a statistically significant correlation between fetal macrosomia and pre-pregnancy body mass index (BMI), gestational weight gain (GWG), parity, advanced maternal age, and male fetal sex was found. Maternal BMI, and GWG were the two risk factors most strongly associated with macrosomia. CONCLUSION: The prevalance of fetal macrosomia is rising among Turkish women. High pre-pregnancy BMI and GWG represent main modifiable risk factors for macrosomia and need more attention from health care providers.

The effect of Helicobacter pylori eradication on proteinuria in patients with primary glomerulonephritis.

INTRODUCTION: Glomerulonephritis is still the primary cause among the diseases causing end stage renal disease. Helicobacter pylori (HP), also having a local proinflammatory effect on gastric mucosa, can trigger a local and systemic inflammatory response, and consequently have a role in the development of extragastrointestinal defects. MATERIAL AND METHODS: The study was composed of patients diagnosed with primary glomerulonephritis who had dyspeptic complaints throughout the diagnosis. Patients who received endoscopic biopsy upon the determination of pathologic findings in their upper gastrointestinal endoscopy were HP positive in their biopsy material. A triple eradication therapy was initiated for HP. RESULTS: The study included 14 female and 19 male patients, 33 in total, whose biopsy material was determined to be HP positive. Before the eradication for HP, we found serum albumin to be 34.0 (19.0-51.0) g/l, serum total protein 58.6 ±12.9 g/l, serum creatinine 0.9 (0.5-1.2) and proteinuria 3069 (652-12392) mg/day in 24-hour urine. After the eradication, however, serum albumin was found to be 40 (20-52) g/l, serum total protein 62.3 ±11.1 g/l, serum creatinine 1.02 (0.6-1.29) mg/dl and proteinuria was 2850 (172-15181) mg/day in 24-hour urine. A comparison of the results showed that a statistically significant difference is established between the serum albumin, total protein and creatinine values (p = 0.001, p = 0.001 and p = 0.021, respectively), but not between proteinuria values in 24-hour urine (p = 0.990). CONCLUSIONS: Patients with primary glomerulonephritis, HP eradication treatment has an effect on serum albumin levels.

A new candidate as a hemostatic agent for difficult situations during variceal bleeding: Ankaferd blood stopper.

Variceal bleeding is the most challenging emergent situation among the causes of upper gastrointestinal bleeding. Despite substantial improvement, a need remains for therapeutic armamentarium of such cases, which is easy, effective and without side-effect. Ankaferd blood stopper (ABS) is a standardized herbal extract acting as a hemostatic agent on the bleeding or injured areas. In this observational study, a total of four patients with variceal bleeding were treated with endoscopic ABS application. The lesions were bleeding gastric varices (n:3) and bleeding duodenal varix (n:1). ABS was selected as a bridge to definitive therapies due to unavailability or inappropriateness of bleeding lesions to conventional measures. ABS was instilled or flushed onto the bleeding areas by sclerotherotherapy needle or heater probe catheter. Periprocedural control of the bleeding was achieved in all instances. Thereafter, on an elective basis, two patients with gastric varices underwent cyanoacrylate injection, while third underwent Transjugular intrahepatic portosystemic shunt and embolization. The patient with duodenal varix refused further therapy, after a few hours after admission and was discharged. He again presented the same day with rebleeding, but died before any attempt could be made to control his bleeding. ABS seems to be effective in cases of variceal bleeding as a bridge to therapy. Its major advantages are the ease of use and lack of side-effects.

Bleeding due to slippage of elastic band during variceal ligation: successful use of Ankaferd blood stopper.

Ankaferd blood stopper (ABS) is a hemostatic agent that induces clot formation by a special protein network which mainly causes powerful erythrocyte aggregation. The use of topical ABS as a hemostatic agent has been approved in Turkey for the management of dermal, external post-surgical and post-dental surgery bleeding. ABS has been successfully used in Dieulafoy lesion and bleeding from gastrointestinal neoplasms. We present a patient with alcoholic cirrhosis who developed severe bleeding during an elective endoscopic variceal ligation (EVL) session due to immediate band slippage, in whom endoscopic topical application of ABS was associated with cessation of bleeding. The major advantages of ABS appear to be ease of use and lack of side effect.

Modulation of the immune response to HBV vaccination by hemodialysis membranes.

INTRODUCTION: Seroconversion response to Hepatitis B virus (HBV) vaccination is limited in uremic patients because of impaired humoral and cellular immune activity. Recent studies show that high-flux (HF) hemodialysis (HD) membranes can improve T cell functions and decrease the proinflammatory cytokine activation more effectively than low-flux (LF) membranes. In regard to HF membranes may have immune modulator effects; we compared the antibody responses to hepatitis B vaccination between HF HD and LF HD membranes. METHODS: One thousand four hundred and eight patients on HD programmed for 4 h three times a week at three different centers with HF or LF membranes were scanned. Anti-HBs levels of these patients who were vaccinated with recombinant DNA HBV vaccine on the 0, 1st, 2nd and 6th month from the beginning were recorded on the 0, 3rd, 6th, 9th and 12th month of vaccination schedule. RESULTS: Seroconversion rate was 84.2% in HF group and 52.7% in LF group on the 6th month (P < 0.01). Ratio of the patients who had >100 IU/l antibody titers in HF group was 22.8%, while it was 10.9% in LF group (P < 0.01). Also on the 9th, 12th and 24th month; seroconversion rates in HF group were higher than LF group: 91.1-70.9% (P < 0.05), 95.0-81.8% (P < 0.05), 92.1-83.7% (P > 0.05), respectively. Ratio of the patients who did not show any seroconversion was higher in LF group than HF group; on the 6th month as 15.8-47.3% (P < 0.001), on the 9th month 8.9-29.1% (P < 0.05), on the 12th month as 5.0-18.2% (P < 0.05), and on the 24th month as 7.9-16.4% (P > 0.05), respectively. CONCLUSION: We showed that ratio of anti-HBs seroconversion response to hepatitis B vaccination in patients receiving HD with HF membranes was higher than LF membranes. This finding suggests that HF membranes may improve immune modulator effects.
