Can inflammatory indexes predict the spontaneous passage of common bile duct stones?

OBJECTIVES: We aimed to determine whether inflammatory indexes (II), including the neutrophil-lymphocyte ratio (NLR), the C-reactive protein (CRP) to albumin ratio (CAR), the CRP-lymphocyte ratio (CLR), and the systemic immune-inflammation index (SIII) can be diagnostic for common bile duct stones (CBDSs) excretion before endoscopic retrograde cholangiopancreatography (ERCP). BACKGROUNDS: Because of the spontaneous clearance, it is mandatory to ascertain the presence of CBDSs before ERCP. METHODS: Retrospectively, we evaluated two groups. Group A included 96 records in which CBDSs existed in magnetic resonance cholangiopancreatography (MRCP) and ERCP. Group B included 36 records in which CBDSs existed in MRCP but not ERCP. IIs were calculated on presentation and before ERCP. RESULTS: Stone detection in ERCP had a 3.992-fold (95% 1.769-9.007) higher probability with a stone larger than 3.25 mm in MRCP. Before ERCP, CAR, and CLR values were higher in group A than in group B (3.88 [1.25-14.14] and 1.24 [0.50-9.66], p = 0.027 versus 8.79 [2.19-35] and 2.67 [1.02-20.05], p = 0.029, respectively). Higher CRP, CAR, and CLR values were considered significant for detecting a stone in ERCP (AUC: 0.627 [0.519-0.739], 0.625 [0.513-0.737], and 0.624 [0.514-0.734], respectively). CONCLUSION: Low CRP, CAR, and CLR values might associate with the spontaneous migration of CBDS.

The Efficacy of Biofeedback Therapy in Patients with Solitary Rectal Ulcer and Dyssynergic Defecation.

BACKGROUND: The treatment of solitary rectal ulcer (SRU) is challenging and controversial; generally, no response to conventional treatments can be obtained, particularly in patients with dyssynergic defecation (DD). We assessed the efficiency of biofeedback therapy (BFT) in patients who did not respond to conservative treatments and had coexistence of SRU and DD. METHODS: BFT responses, as well as anorectal manometry and rectoscopy results of 20 patients with the coexistence of SRU and DD, were assessed. RESULTS: Mean age was 32.5 years. Of the patients, 12 were female, and 8 of them were male. An average of 12 sessions of BFT was performed on the patients. Ulcer disappeared in 11 patients (55%) after BFT, and the ulcer size decreased in 3 patients (15%). However, ulcers healed in 9 (90%) of 10 patients whose DD pattern disappeared following BFT, and ulcers healed in only 20% of patients whose DD pattern continued (p = 0.005). The change in anal resting pressure after BFT was significant (p = 0.016). Ulcers were healed in 87.5% (7/8) of the patients whose anal resting pressure decreased after BFT and whose DD disappeared, while ulcers remained untreated in 85.7% of the patients whose anal resting pressure decreased, but the DD pattern continued (p = 0.005). CONCLUSIONS: SRU patients with DD are typically unresponsive to medical treatments. Ameliorating anorectal dyssynergia should be the priority of treatment in these patients. BFT is an effective treatment for DD. BFT enhances the healing of ulcers in patients with SRU by restoring coordination of the pelvic floor.

Vagococcus fluvialis first isolated from the ascitic fluid of a patient with cirrhosis.

Ascites is the most common complication of the decompansated cirrhosis. The most common organisms isolated in patients with ascidic fluid infections and spontaneous bacterial peritonitis (SBP) are intestinal pathogens including Escherichia coli, Gram-positive cocci (mainly Streptococcus species) and Enterococci. As an infectious pathogen Vagococcus spp. can be isolated from animals such as pigs, cats, horses and fishes and also rarely in humans. In this paper, we present a case of Vagococcus fluvialis peritonitis which is the first one reported in a cirrhotic patient with ascites.

Favorable efficacy of adalimumab treatment in experimental acute pancreatitis model.

BACKGROUND: Acute pancreatitis is a clinical picture with a wide range of symptoms from mild inflammation to multiorgan failure and death. The aim of this study is to investigate the effects of Adalimumab (ADA) on inflammation and apoptosis in a cerulein-induced acute pancreatitis model in rats. METHODS: Experimental cerulein-induced acute pancreatitis model was created by applying 4 intraperitoneal cerulein injections at 1-h intervals. A total of 40 rats, 8 in each group, were randomly distributed into five groups. In the groups that ADA treatment was given, two different doses of ADA were administered 5 mg/kg and 20 mg/kg as low and high doses, respectively. The rats were sacrificed 12 h after the last intraperitoneal administration of ADA. Blood samples were obtained from each rat for amylase, IL-6, and IL-1ß measurements. Hematoxylin and Eosin (H&E) stains were used to undertake the histopathological analysis of the pancreas. The terminal deoxynucleotidyl transferase-mediated nick-end-labeling (TUNEL) method was used to evaluate apoptosis. RESULTS: : Plasma amylase, IL-6, and IL-1ß levels were significantly elevated in acute pancreatitis groups (p < 0.05). It was determined that both low (5 mg/kg) and high doses (20 mg/kg) of ADA ameliorated the parameters (plasma amylase, IL-6, and IL-1ß) (p < 0.05). Although significant improvements were detected in the Schoenberg scoring system and the apoptotic index from the TUNEL method after highdose ADA treatment, no significant amelioration was observed in the histopathological examinations in the low-dose ADA group. DISCUSSION: : It has been determined that the administration of high-dose ADA effectively alleviated the symptoms of acute pancreatitis and reduced the level of apoptosis. In line with the findings of our study, we have predicted that high-dose (20 mg/kg) ADA can be used as an effective and safe drug in the treatment of patients with acute pancreatitis.

Assessment of severity and mortality of COVID-19 with anti-A1 and anti-B IgM isohaemagglutinins, a reflection of the innate immune status.

AIMS: The relationship between the innate immune system that creates the polysaccharide antibody response and COVID-19 is not fully understood. In this study, it was aimed to determine the predictive values of isohaemagglutinins in COVID-19 severity/mortality. METHODS: Approximately 15 440 patients diagnosed with COVID-19 were examined, and a total of 286 patients with anti-B and anti-A1 IgM isohaemagglutinins test results were randomly enrolled in the study. These patients were stratified into two groups according to anti-A1 (n: 138 blood type B or O) and anti-B (n: 148 blood type A) IgM isohaemagglutinins. Anti-A1 or/and anti-B IgM, biochemical parameters, symptoms, chronic diseases, hospitalisation status, intubation status, admission to intensive care unit (ICU) and exitus status were recorded and evaluated for all patients. RESULTS: Anti-A1 IgM and anti-B IgM were significantly lower in ICU patients (7.5 ± 9.9 vs 18.0 ± 20.4 and 5.5 ± 6.3 vs 19.3 ± 33.6 titres, respectively; P < .01) and in exitus patients (3.8 ± 3.6 vs 16.7 ± 18.7 and 3.5 ± 4.7 vs 16.9 ± 29.6 titres respectively; P < .01). In the ROC analysis performed to differentiate between exitus and discharge within groups, the sensitivity of anti-B IgM and anti-A1 IgM at cut-off ≤4 was 88.9% and 79.6%, specificity 66.0% and 73.4%, and AUC 0.831 and 0.861, respectively (P < .01). Anti-A1 IgM decreased the mortality risk 0.811 times per unit while anti-B IgM decreased 0.717 times (P < .01). CONCLUSION: Anti-B and anti-A1 isohaemagglutinins, which are an expression of the innate immune system, can be used to predict the severity and mortality of COVID-19 disease.

Long-term proton pump inhibitor use is a risk factor for mortality in patients hospitalized for COVID-19

Background and aim: The aim of this study is to evaluate whether the long-term (≥4 weeks) use of proton pump inhibitors (PPIs) is a risk factor for intubation requirement and mortality in patients hospitalized for COVID-19. Materials and methods: In this multicentric retrospective study, a total of 382 adult patients (≥18 years of age) with confirmed COVID-19 who were hospitalized for treatment were enrolled. The patients were divided into two groups according to the periods during which they used PPIs: the first group included patients who were not on PPI treatment, and the second group included those who have used PPIs for more than 4 weeks. Results: The study participants were grouped according to their PPI usage history over the last 6 months. In total, 291 patients did not use any type of PPI over the last 6 months, and 91 patients used PPIs for more than 4 weeks. Older age (HR: 1.047, 95% CI: 1.026­1.068), current smoking (HR: 2.590, 95% CI: 1.334­5.025), and PPI therapy for more than 4 weeks (HR: 1.83, 95% CI: 1.06­2.41) were found to be independent risk factors for mortality. Conclusion: The results obtained in this study show that using PPIs for more than 4 weeks is associated with negative outcomes for patients with COVID-19. Patients receiving PPI therapy should be evaluated more carefully if they are hospitalized for COVID-19 treatment.

Pentoxifylline has favorable preventive effects on experimental chronic pancreatitis model.

Background: To investigate the protective efficacy of pentoxifylline through biochemical parameters and histopathological scores in a caerulein- and alcohol-induced experimental model of chronic pancreatitis in rats.Methods: A model of chronic pancreatitis with caerulein and alcohol was created in female rats of the genus Sprague Dawley. Pentoxifylline was administered in doses of 25 mg/kg (low dose) and 50 mg/kg (high dose) as a protective agent. Each group contained 8 animals. The groups were: group 1 (control group); caerulein + alcohol, group 2 (low-dose pentoxifylline group); caerulein + alcohol + pentoxifylline 25 mg/kg, group 3 (high-dose pentoxifylline group); caerulein + alcohol + pentoxifylline 50 mg/kg, group 4 (placebo); caerulein + alcohol + saline, group 5 (sham group); only saline injection.Rats were sacrificed 12 h after the last injection, and TNF-α, TGF-ß, MDA, and GPx concentrations were measured in blood samples. The histopathologic examination was conducted by a pathologist who was unaware of the groups.Results: The biochemical results of the treatment groups (group 2 and group 3) were statistically significantly lower compared with the control group (group 1) (p < .05). The difference between the low-dose treatment group (group 2) and high-dose treatment group (group 3) was significant in terms of biochemical parameters (p < .05). The difference between group 2 and the control group was not significant in terms of histopathologic scores (p > .05), whereas the difference between the group 3 and the control group was statistically significant (p < .05).Conclusions: As a result, pentoxifylline, which has anti-inflammatory and antioxidant properties, was shown to have protective efficacy in an experimentally generated model of chronic pancreatitis.

Review-Current Concepts in Inflammatory Skin Diseases Evolved by Transcriptome Analysis: In-Depth Analysis of Atopic Dermatitis and Psoriasis.

During the last decades, high-throughput assessment of gene expression in patient tissues using microarray technology or RNA-Seq took center stage in clinical research. Insights into the diversity and frequency of transcripts in healthy and diseased conditions provide valuable information on the cellular status in the respective tissues. Growing with the technique, the bioinformatic analysis toolkit reveals biologically relevant pathways which assist in understanding basic pathophysiological mechanisms. Conventional classification systems of inflammatory skin diseases rely on descriptive assessments by pathologists. In contrast to this, molecular profiling may uncover previously unknown disease classifying features. Thereby, treatments and prognostics of patients may be improved. Furthermore, disease models in basic research in comparison to the human disease can be directly validated. The aim of this article is not only to provide the reader with information on the opportunities of these techniques, but to outline potential pitfalls and technical limitations as well. Major published findings are briefly discussed to provide a broad overview on the current findings in transcriptomics in inflammatory skin diseases.

Comparison of organically and conventionally produced Batavia type lettuce stored in modified atmosphere packaging for postharvest quality and nutritional parameters.

BACKGROUND: The impacts of organic and conventional production systems on postharvest life and quality parameters of Batavia type 'Caipira' lettuce heads (Lactuca sativa L.) were investigated. Harvested lettuce heads grown in two different production systems were stored at 0 °C temperature and 95-98% relative humidity for 20 days in modified atmosphere packaging. RESULTS: The lowest weight loss, the highest ascorbic acid content and antioxidant activity were obtained from the organic production system (Org-2). The conventional production system had higher total soluble solids, titratable acidity, and total phenolic contents. During the shelf-life period at 20 °C, the weight losses of lettuce heads grown conventionally were higher than with the other production system. Conventionally grown heads had higher titratable acidity and total phenolic contents than organically grown heads. The highest titratable acidity and h° values were obtained from the plants grown under conventional and organic production systems (Org-2), while the highest chroma value and antioxidant activity were detected from the control treatment. The highest ascorbic acid content was detected in the control treatment, but the effects of control, organic (Org-2) and conventional production systems on ascorbic acid content were not statistically significant. CONCLUSION: The results indicated that the organic production system (Org-2) was the most effective treatment in prolonging postharvest life and protecting the quality of Batavia type 'Caipira' lettuce heads stored in modified atmosphere packaging. © 2018 Society of Chemical Industry.

Cloning and molecular characterization of thiol-specific antioxidant gene of Leishmania tropica Turkey isolate

Background/aim: Thiol-specific antioxidant (TSA) protein is one of the most promising molecules among candidates for vaccine against cutaneous leishmaniasis. It was found to be significantly protective against different Leishmania species. In this study, cloning and molecular characterization of thiol-specific antioxidant gene of L. tropica Turkey isolate (LtTSA) were aimed. Materials and methods: LtTSA was amplified by PCR using the specific primers of TSA gene and cloned into the pcDNA3.1 vector. The cloning was confirmed by PCR screening, restriction enzyme reactions, and DNA sequence analysis. Finally, three-dimensional structure and antigenic properties of the protein encoded by the LtTSA were determined Results: Six hundred base pair bands belonging to LtTSA were shown with electrophoresis. It was found that LtTSA and its encoded protein have high similarity with different Leishmania species. LtTSA protein consisting of 199 amino acids was found to have 7 different antigenic regions. Conclusion: LtTSA and its encoded TSA protein were found to be highly immunogenic and similar to TSA proteins previously tested as a vaccine candidate.

Tp-e Interval, Tp-e/QTc Ratio, and Fragmented QRS Are Correlated with the Severity of Liver Cirrhosis.

BACKGROUND: Arrhythmias and electrocardiographic changes are reported in several noncardiac diseases, including liver cirrhosis (LC). We intended to evaluate the interval from the peak to the end of the electrocardiographic T wave (Tp-e), Tp-e/QTc ratio, and fQRS as presumed markers of arrhythmias in LC. METHODS: In this cross-sectional study, a total of 88 consecutive patients with LC according to clinical, biological, ultrasonographic, or histological criteria and 73 control subjects were enrolled. The severity of cirrhosis was classified according to Pugh-Child's classification and Model for End-Stage Liver Disease (MELD) score. Tp-e interval, Tp-e/QTc ratio, and fQRS rates were measured from the 12-lead electrocardiogram. RESULTS: Tp-e interval, Tp-e/QTc ratio and fQRS rates were significantly increased in parallel to the severity of LC (P < 0.001, P < 0.001, and P = 0.003, respectively). In correlation analysis, Pugh-Child stage showed a significantly positive correlation with Tp-e interval (r = 0.462, P < 0.001), QTc interval (r = 0.373, P < 0.001), Tp-e/QTc ratio (r = 0.352, P < 0.001), and fQRS (r = 0.407, P < 0.001). Furthermore, Tp-e interval (r = 0.414, P < 0.001) and Tp-e/QTc ratio (r = 0.426, P< 0.001) had significant positive correlation with MELD score. CONCLUSIONS: Our study demonstrated that Tp-e interval, Tp-e/QTc ratios, and fQRS rates were significantly increased in parallel to the severity of LC. Thus, these findings may implicate that Tp-e interval, Tp-e/QTc ratio, and fQRS may be novel and useful indicators for prediction of arrhythmias in LC.

Predictive value of C-reactive protein/albumin ratio in acute pancreatitis.

BACKGROUND: Serum C-reactive protein (CRP) increases and albumin decreases in patients with inflammation and infection. However, their role in patients with acute pancreatitis is not clear. The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients. METHODS: This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015. Ranson scores, Atlanta classification and CRP/albumin ratios of the patients were calculated. RESULTS: The CRP/albumin ratio was higher in deceased patients compared to survivors. The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time, CRP and erythrocyte sedimentation rate. In addition to the CRP/albumin ratio, necrotizing pancreatitis type, moderately severe and severe Atlanta classification, and total Ranson score were independent risk factors of mortality. It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk. A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity. It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28. Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death. CONCLUSION: The CRP/albumin ratio is a novel but promising, easy-to-measure, repeatable, non-invasive inflammation-based prognostic score in acute pancreatitis.

Management of suspected common bile duct stone: diagnostic yield of current guidelines.

BACKGROUND: The American Society for Gastrointestinal Endoscopy (ASGE) has recently published a guideline for suspected CBDS with the intention of reducing unnecessary ERCP and thereby complications. The aim of this study was to assess the diagnostic efficacy of the ASGE guideline. METHODS: Data of patients who underwent ERCP with suspected CBDS were analyzed retrospectively. Patients were classified into high, intermediate and low risk groups based on predictors that have been suggested by the ASGE. Very strong predictors of the presence of ductal stones included: CBDS on transabdominal ultrasonography (US), clinical ascending cholangitis or total bilirubin (TBIL) >4 mg/dL). Strong predictors included dilated CBD >6 mm on US with gallbladder in situ and TBIL level of 1.8-4.0 mg/dL whereas moderate predictor included abnormal liver biochemical test other than bilirubin, age more than 55 years and clinical findings of biliary pancreatitis. RESULTS: Of 888 enrolled patients, 704 had CBDS demonstrated by ERCP and the remainder did not. All very strong and strong predictors were found to be significantly higher among patients who had CBDS. Detection of CBDS by ultrasonography and a dilated common biliary duct were observed to be independent risk factors associated with the existence of CBDS. The high risk group had a high (86.7%) positive predictive value (PPV), however, sensitivity and specificity were observed to be moderate (67.8% and 60.3% respectively). PPV was 67.9% in the intermediate risk group and the sensitivity and specificity were very low (31.9% and 42.3%). DISCUSSION: The probability of CBDS was observed to be high in the intermediate and high risk groups. However due to low sensitivity and specificity values, the ASGE guideline needs additional or different predictors.

Clinical and histological features of idiosyncratic liver injury: Dilemma in diagnosis of autoimmune hepatitis.

AIM: Drug-induced liver injury (DILI) is becoming a worldwide problem with its still unexplained properties. METHODS: The data of patients who were diagnosed with DILI between January 2008 and December 2013 were assessed. RESULTS: Five patients had been diagnosed with intrinsic and 82 patients with idiosyncratic DILI. The most common causative agents were antimicrobial drugs. The most common injury pattern was hepatocellular. When patients with bilirubin levels of more than 5 mg/dL were divided into two groups according to receiving steroid therapy (n = 11) or not (n = 40), there was not any significant difference according to their clinical results (P > 0.05). Five of the idiosyncratic DILI patients were diagnosed with drug-induced autoimmune hepatitis (DI-AIH). In histopathological examination, hepatic rosette formation and emperipolesis were observed to be more common among patients with DI-AIH when compared with ones without (P < 0.05). Interestingly, in the remaining patients with DILI (n = 77), three of them were diagnosed with classic autoimmune hepatitis during long-term follow up (range, 11-51 months). CONCLUSION: The most common causes were antimicrobials, but any agents that have not been defined to cause DILI can induce DILI. The efficacy of steroids in DILI has not been observed but all deaths were observed in the steroid-free group. The association of DILI and AIH was observed in two different types in terms of diagnosis in our study. The first association was DI-AIH. The second one is the classical AIH which developed in three patients after a few months following spontaneous recovery of DILI.

Is ischemia modified albumin a disease activity marker for inflammatory bowel diseases?

BACKGROUND AND AIM: We aimed to identify ischemia-modified albumin (IMA) levels in inflammatory bowel disease (IBD) and IBD subgroups, and to examine its relation with disease activity index. METHODS: Sixty-eight patients with IBD (35 ulcerative colitis [UC] and 33 crohn disease [CD]) and 65 healthy volunteers were included in the study. Rachmilewitz scoring system (endoscopic activity index [EAI]) was used to determine UC activity, and as for CD activity, CD activity index (CDAI) scoring was used. IMA measurement was performed with ELISA kit. RESULTS: Ischemia-modified albumin levels in IBD, UC, and CD groups were comparably higher than the control group (37.7 ng/mL vs 42.4 ng/mL vs 36.4 ng/mL vs 21.8 ng/mL, respectively; P < 0.05). In IBD group, a positive correlation was identified between IMA level and CRP (r = 0.325, P = 0.011), EAI(r = 0.302, P = 0.020), and CDAI (r = 0.311, P = 0.013). In stepwise regression model; it was identified that IMA(OR = 1.496; P = 0.016) and CRP(OR = 3.457; P = 0.015) are predictors of IBD in comparison with the control group. In linear regression model, it was identified that risk factors such as log(IMA) and log(CRP) were independent predictors of log(CDAI) and log(EAI) levels. CONCLUSION: This is the first study showing that IMA levels in IBD were determined higher in comparison with the control group. Moreover, IMA being a predictor for IBD and being positively correlated with disease activity indexes were determined for the first time in the study. In accordance with these results, it is possible to say that IMA in IBD might be related with the pathogenesis of disease and correlated with the severity of the disease.

Transient Ischemic Attacks of Spinal Cord due to Abdominal Aortic Aneurysm Thrombus.

Thrombosis due to abdominal aortic aneurysm is a rare condition that causes high mortality. Transient ischemic attack of the spinal cord can occur as a result of trash emboli from thrombus in abdominal aortic aneurysm. This condition generally occurs during operation of abdominal aortic aneurysm; very rarely, it can also be seen in laminated abdominal aortic aneurysm. Here, we present a case of a patient presenting with bilateral lower extremity paralysis resulting from transient ischemic attack of the spinal cord due to infrarenal abdominal aortic aneurysm.

Kisspeptin levels in idiopathic hypogonadotropic hypogonadism diagnosed male patients and its relation with glucose-insulin dynamic.

Male hypogonadism is defined as the deficiency of testosterone or sperm production synthesized by testicles or the deficiency of both. The reasons for hypogonadism may be primary, meaning testicular or secondary, meaning hypothalamohypophyseal. In hypogonadotropic hypogonadism (HH), there is indeficiency in gonadotropic hormones due to hypothalamic or hypophyseal reasons. Gonadotropin-releasing hormone (GnRH) is an important stimulant in releasing follicular stimulant hormone (FSH), mainly luteinizing hormone (LH). GnRH omitted is under the effect of many hormonal or stimulating factors. Kisspeptin is present in many places of the body, mostly in hypothalamic anteroventral periventricular nucleus and arcuate nucleus. Kisspeptin has a suppressor effect on the metastasis of many tumors such as breast cancer and malign melanoma metastases, and is called "metastin" for this reason. Kisspeptin is a strong stimulant of GnRH. In idiopathic hypogonadotropic hypogonadism (IHH) etiology, there is gonadotropic hormone release indeficiency which cannot be clearly described. A total of 30 male hypogonatropic hypogonadism diagnosed patients over 30 years of age who have applied to Haydarpasa Education Hospital Endocrinology and Metabolic Diseases Service were included in the study. Compared to the control group, the effect of kisspeptin on male patients with hypogonatropic hypogonadism and on insulin resistance developing in hypogonadism patients was investigated in our study. A statistically significant difference was detected between average kisspeptin measurements of the groups (p < 0.01). Kisspeptin measurement of the cases in the patient group were detected significantly high. No statistically significant relation was detected among kisspeptin and LH/FSH levels. Although a positive low relation was detected between kisspeptin measurements of patient group cases and homeostasis model assessment of insulin resistance (HOMA-IR) measurements, this relation was statistically insignificant. When the patient and control groups were compared for HOMA-IR, no statistically significant difference was detected. The reason for high kisspeptin levels in the patient group compared to the control group makes us consider that there may be a GPR54 resistance or GnRH neuronal transfer pathway defect. When patients and control groups were compared for HOMA-IR, the difference was not statistically significant. It is considered that kisspeptin is one of the reasons for hypogonatropic hypogonadism and has less effect on insulin resistance.

Relationship between socioeconomic level, and the prevalence of masked hypertension and asymptomatic organ damage.

BACKGROUND: This study aimed to determine the prevalence of masked hypertension (MHT) and its association with asymptomatic organ damage (AOD) in a low socioeconomic district of Ankara, Turkey. MATERIAL AND METHODS: We retrospectively reviewed data obtained from the medical records of 712 patients with no known diagnosis of hypertension who presented to a polyclinic due to symptoms related to elevated blood pressure (BP) and were screened for MHT. Essential hypertension (EHT) existed in 86 patients screened for AOD. The presence of AOD in patients diagnosed with MHT and EHT was recorded. RESULTS: Among the 712 patients, 206 were diagnosed with EHT. Among the remaining 506 patients, 73 were diagnosed with MHT. The patients with MHT had significantly higher left ventricular mass index, carotid intima-media thickness, and 24-h urinary microalbuminuria level (all indicators of AOD) than those with EHT. CONCLUSIONS: A significantly higher percentage of patients with MHT had AOD, as compared to those with EHT, in a low socioeconomic district of Ankara. Based on this finding, patients who present with hypertensive symptoms but have a normal BP should be advised to measure their BP at home.

Effectiveness of interleukin-1 receptor antagonist (Anakinra) on cerulein-induced experimental acute pancreatitis in rats.

AIM: Acute pancreatitis (AP) is defined as an inflammatory disease of the pancreas. The purpose of this study was to examine the effectiveness of Anakinra on cerulein-induced experimental pancreatitis rat model by using the results of biochemical and histopathological findings. MATERIALS AND METHODS: Cerulein was administered to induce AP in rats. Group 1 was the sham group. Subcutancerulein was injected to the rats in group 2 for experimental pancreatitis group. In groups 3 and 4, 100 and 50 mg/kg intraperitoneal Anakinra were injected after the induction of experimental pancreatitis by subcutaneous cerulein in rats, respectively. Lastly, in group 5, rats were injected with intraperitoneal saline and subcutan cerulean for placebo group. The following parameters were evaluated: histopathological score of pancreatitis, apoptotic index, amylase, lipase, TNF-α levels, IL-1ß and the leukocyte count. RESULTS: When the results of serum amylase, lipase, TNF-α and IL-1ß levels, the leukocyte count, histopathologic scores and apoptotic indices of control group compared to the results of other groups, the differences exhibited statistical significance (all p < 0.05). On the other hand, when the results of fourth group compared with the results of third group, the data demonstrated statistical insignificance (p > 0.05). However, no any significant differences were found between the results of fourth and fifth groups (p > 0.05). CONCLUSION: In the light of these results, cerulein is an appropriate agent for experimental AP rat model and Anakinra has a favorable therapeutic effect on acute experimental pancreatitis model. Moreover, Anakinra significantly decreases cerulein-related pancreatic tissue injury and pancreatic apoptosis.
