RESUMEN
BACKGROUND: Inflammatory bowel disease (IBD), which is an umbrella term used for ulcerative colitis (UC) and Crohn's disease (CD), is associated with an increased risk for atherosclerotic cardiovascular disease (CVD). We aimed to investigate the association of local and systemic biomarkers of inflammation and gut microbiota-derived metabolite trimethylamine N-oxide (TMAO) with endothelial and coronary microvascular dysfunction in IBD. METHODS: A total of 56 patients with IBD (20 with UC and 36 with CD) and 34 age and gender matched controls were included. For all participants, samples were collected to analyze faecal calprotectin, and TMAO concentrations. Ultrasound-based examinations were done to measure flow-mediated vasodilatation (FMD) and coronary flow velocity reserve (CFVR). RESULTS: Patients with IBD had lower CFVR (2.07 (1.82-2.40)) and FMD (8.7 ± 3.7) as compared to controls (2.30 (2.07-2.74), p = 0.005 and 11.9 ± 6.8, p = 0.03). In patients with IBD, TMAO concentration (r = -0.30, p = 0.03), C-reactive protein (r = -0.29, p = 0.03) and WBC count (r = -0.37, p = 0.006) had a significant negative correlation with CFVR, and TMAO (ß = -0.27, 95 % CI: -0.23 to -0.02) and WBC count (ß = -0.31, 95 % CI: -0.56 to -0.06) were significant predictors of CFVR after multivariate adjustment. None of the biomarkers of inflammation or TMAO showed significant correlations with FMD. In patients with UC, TMAO showed a significant correlation with both CFVR (r = -0.55, p = 0.01) and FMD (r = -0.60, p = 0.005) while only WBC count had a statistically significant correlation with CFVR (r = -0.49, p = 0.004) in patients with CD. CONCLUSIONS: Gut microbiota-derived metabolite TMAO and biomarkers of systemic inflammation are associated with measures of endothelial/coronary microvascular dysfunction in patients with IBD.

BACKGROUND: A history of preeclampsia (pPE) and gestational diabetes (pGDM) are female-specific risk markers for atherosclerosis and future cardiovascular risk. In addition to increasing the risk of established risk factors for atherosclerosis, such as hypertension or diabetes, evidence suggests that pregnancy-related complications can also directly accelerate atherosclerosis by inducing endothelial dysfunction. A combination of both conditions is seen in a subset of patients with pregnancy, though it is not known whether this combination increases the overall risk for cardiovascular events. AIMS: Present study aimed to find the impact of combined pPE/pGDM on the prevalence of coronary microvascular dysfunction (CMD). METHODS: A total of 24 patients with combined pPE/pGDM, 19 patients with isolated pPE and 63 patients with pGDM were included to the present study and a further 36 healthy women with no previous pregnancy-related complications served as controls. Coronary flow reserve was measured using echocardiography and CMD was defined as a coronary flow reserve ≤2.5. RESULTS: Patients with combined pPE/pGDM had a high prevalence of CMD (91%), which was significantly higher than controls (5.6%, p < 0.001) and patients with pGDM (55%, p = 0.01). A history of pPE on top of pGDM was associated with an increased risk of CMD (HR:6.28, 95%CI:1.69-23.37, p = 0.006) after multivariate adjustment, but pGDM did not increase the odds for CMD in those with pPE. CONCLUSIONS: Combined pPE/pDM is associated with a very high prevalence of CMD, which may indicate an increased risk for future cardiovascular events.

BACKGROUND: Celiac disease (CD) is an enteropathy characterized with immune reaction to gliadin protein. AIM: In this study, we aimed to assess effect of CD on coronary microvascular circulation and the association between coronary flow velocity reserve (CFVR) and hs-CRP/Albumin ratio. MATERIAL AND METHODS: Study was conducted between March 2017 and November 2018 with CD at Umraniye Training and Research Hospital Gastroenterology Clinic. CFVR was defined as the ratio of hyperemic to baseline diastolic peak velocities. CFVR ≥ 2.0 was considered normal. C-reactive protein/albumin ratio (CAR) was calculated as hs-CRP/albumin. RESULTS: Serum albumin (4.27 ± 0.56 vs 4.50 ± 0.34; P value: .04) level was significantly lower in celiac group but higher Hs-CRP (2.44 ± 1.24 vs 1.82 ± 1.29; P value < .01), hs-CRP/albumin ratio (0.57 ± 0.30 vs 0.41 ± 0.31; P value: .03) were recorded in celiac group. Both hyperemic flow and CFVR substantially lower in the celiac group compared to controls. In univariate analysis; age, hs-CRP, and hs-CRP/albumin ratio were associated with low CFVR and hs-CRP/albumin level was an accurate predictor of low CFVR at the ROC curve. CONCLUSION: In this study, we found that in patients with CD, coronary flow reserve is impaired.

BACKGROUND AND AIM: Increased incidence of coronary vascular events in patients with inflammatory bowel disease (IBD) is known. However, the association between coronary microvascular function and IBD has not been fully defined. We aimed to investigate whether coronary flow reserve (CFR) and left ventricular diastolic function were impaired in IBD patients. METHODS: Seventy-two patients with IBD (36 patients with ulcerative colitis [UC] and 36 Crohn's disease [CD]) were registered. Each subject was evaluated after a minimum 15-day attack-free period. For the control group, 36 age- and sex-matched healthy volunteers were included into the study. IBD clinical disease activity in UC was assessed by the Truelove-Witts Index (TWAS) and in CD by the Crohn's Disease Activity Index (CDAI). In each subject, CFR was measured through transthoracic Doppler echocardiography. RESULTS: Compared to the controls, the CD group and UC group had significantly higher high-sensitivity C-reactive protein (hs-CRP) and erythrocyte sedimentation rate. Baseline diastolic peak flow velocity (DPFV) of the left anterior descending artery (LAD) was significantly higher in the IBD group (24.1±3.9 vs. 22. 4±2.9, p<0.05), and hyperemic DPFV (56.1±12.5 vs. 70.6±15.3, p<0.05) and CFR (2.34±0.44 vs. 3.14±0.54, p<0.05) were significantly lower in the IBD group than in the control group. In stepwise linear regression analysis, hs-CRP and lateral Em/Am ratio were independently correlated with CFR. CONCLUSION: CFR, reflecting coronary microvascular function, is impaired in patients with IBD. CFR and left ventricular diastolic function parameters are well correlated with hs-CRP.

BACKGROUND: Gestational diabetes mellitus (GDM) is defined as glucose intolerance that has begun during pregnancy. Recent studies have proven that development of atherosclerosis may be established in this population even without presence of type 2 diabetes. For assessment of atherosclerosis, epicardial fat thickness (EFT) is recently being used as a surrogate marker. In this study, we aimed to prove that women with GDM history are more inclined to have higher EFT levels than women without GDM history. METHODS: Sixty-two patients with previous GDM and 33 age- and sex-matched controls were allocated. Epicardial fat thicknesses of the subjects were measured with transthorasic echocardiography and carotid intima media thickness (c-IMT) was measured with ultrasound. Insulin resistance (IR) of each subject was assessed with Homeostasis model of assessment-insulin resistance (HOMA-IR). RESULTS: Carotid IMT and EFT were significantly higher in previous GDM group than controls. Serum gamma-glutamyl transferase (GGT), uric acid, and high-sensitivity C-reactive protein (hs-CRP) levels were also found significantly higher in the patients with previous GDM as compared to the controls. We observed that carotid IMT (ß = 310, P = 0.003), total cholesterol (ß = 315, P = 0.002), BMI (ß = 308, P = 0.002), HbA1c (ß = 227, P = 0.018), and HOMA-IR (ß = 184, P = 0.049) were independently correlated with EFT. CONCLUSIONS: Although the number of patients included in this study is limited, high EFT results may indicate presence of atherosclerosis in women with previous GDM.

INTRODUCTION AND OBJECTIVE: Contrast-induced nephropathy (CIN) significantly increases the morbidity and mortality of patients. The aim of this study is to investigate and compare the protective effects of isotonic sodium chloride with sodium bicarbonate infusion and isotonic sodium chloride infusion with diltiazem, a calcium channel blocker, in preventing CIN. MATERIALS AND METHODS: Our study included patients who were administered 30-60 mL of iodinated contrast agent for percutaneous coronary angiography (PCAG), all with creatinine values between 1.1 and 3.1 mg/dL. Patients were divided into three groups and each group had 20 patients. The first group of patients was administered isotonic sodium chloride; the second group was administered a solution that of 5% dextrose and sodium bicarbonate, while the third group was administered isotonic sodium chloride before and after the contrast injection. The third group received an additional injection of diltiazem the day before and first 2 days after the contrast injection. All of the patients' plasma blood urea nitrogen (BUN) and creatinine levels were measured on the second and seventh day after the administration of intravenous contrast material. RESULTS: The basal creatinine levels were similar for all three groups (p > 0.05). Among a total of 60 patients included in the study, 16 patients developed acute renal failure (ARF) on the second day after contrast material was injected (26.6%). The number of patients who developed ARF on the second day after the injection in the first group was five (25%), in the second group was six (30%) and the third group was five (25%) (p > 0.05). CONCLUSION: There was no significant difference between isotonic sodium chloride, sodium bicarbonate and isotonic sodium chloride with diltiazem application in prevention of CIN.

In this study, we have measured coronary flow reserve (CFR) using transthoracic echocardiography and brachial artery flow-mediated dilatation using vascular ultrasound in 36 subjects with masked hypertension (MH), 62 patients with sustained hypertension (SH), 40 patients with white-coat hypertension (WCH), and 39 healthy volunteers. CFR was significantly lower in the MH and SH groups (2.30 ± 0.39 and 2.28 ± 0.52, respectively) than in the control and WCH groups (2.85 ± 0.39 and 2.77 ± 0.41, respectively; P < .05). CFR was significantly impaired in patients with MH and SH compared with WCH and normotensive subjects. MH and SH groups are comparable with regard to cardiovascular risks and target organ damage.

Lysinuric protein intolerance (LPI) is a rare, inherited aminoaciduria caused by biallelic pathogenic variants in the amino acid transporter gene SLC7A7 (OMIM *603593). Individuals with LPI show extreme variability in their clinical presentation, and LPI is included in the differential diagnosis of several disorders such as urea cycle disorders, lysosomal storage diseases, malabsorption diseases, autoimmune disorders, hemochromatosis, and osteoporosis. The phenotypic variability of LPI and the lack of a specific clinical presentation have caused various misdiagnoses. Here, we report two siblings diagnosed in their 4th decade of life with LPI, manifesting rare hyperferritinemia. Additionally, they presented with short stature, multiple bone fractures due to osteoporosis, and they showed an aversion to protein-rich food. Using a combination of exome sequencing, microarray analysis and qPCR, we identified a novel homozygous deletion in SLC7A7 encompassing exons 3 to 10, which is predicted to lead to disruption of SLC7A7 function. This is the first report of lysinuric protein intolerance in a Turkish family associated with this so far unknown deletion in SLC7A7.
RESUMEN
Photodynamic inactivation (PDI) has a potential application for food preservation that can minimize food pathogens posing risks to consumer health. This study aimed to evaluate the antibacterial activity of 405â nm light-emitting diodes (LEDs) illumination in the presence of carvacrol and curcumin against Salmonella Enteritidis and S. Enteritidis PT4 at different temperatures (4 °C, 25 °C and 37 °C) and time parameters (15â min, 30â min and 45â min) in the illumination system. Compared to their individual treatment, the decrease in the bacterial population was stronger in bacteria treated with LEDs + carvacrol or LEDs + curcumin. Co-application of carvacrol or curcumin with LEDs at 37 °C showed strong antibacterial activity against both bacteria depending on the application time. Co-application at 37 °C for 45â min completely inhibited the growth of S. Enteritidis. LEDs, curcumin, carvacrol applications alone or LEDs + curcumin, LEDs + carvacrol applications caused a decrease in bacterial population in proportion to the increase in the storage temperature and application times. These results showed that carvacrol or curcumin potentiates LEDs illumination therapy against both bacteria. Future studies on adapting the PDI system to control bacteria in a variety of foods may help develop novel strategies to fight against foodborne bacterial pathogens.

Mortality from cardiovascular disease has been found to be increased in patients with systemic lupus erythematosus (SLE). Coronary flow reserve (CFR) measurement is used both to assess epicardial coronary arteries and to examine the integrity of coronary microvascular circulation. Oxidative stress, enhancing modification of plasma lipids, is also associated with atherosclerotic events in lupus patients. Impairment of CFR and TAS has been shown to be an early manifestation of coronary atherosclerosis. Forty patients with SLE and 33 healthy volunteers were included in this study. Echocardiographic examination included left ventricular myocardial velocity measurements and coronary flow reserve (CFR) measurement. Serum total antioxidant status levels (TAS) also were measured using TAS kit. Lateral myocardial early peak velocity (Em) and lateral Em/Am ratio did not differ between the groups, but lateral myocardial atrial peak velocity (Am) was significantly higher in SLE group than the control group. Baseline coronary diastolic peak flow velocity (DPFV) of left anterior descending was similar in both the groups. However, hyperemic DPFV and CFR (2.50 ± 0.42 vs. 3.09 ± 0.45, P < 0.0001) were significantly lower in the SLE group than in the control group. CFR significantly and inversely correlated with CRP and significantly correlated with TAS. Subclinical coronary microvascular dysfunction can occur in SLE patients without traditional cardiovascular risk factors, probably associated with underlying inflammation and impairment of TAS.

BACKGROUND: Dysphagia is a geriatric syndrome. Changes in the whole body that occur with aging also affect swallowing functions and cause presbyphagia. This condition may progress to oropharyngeal and/or esophageal dysphagia in the presence of secondary causes that increase in incidence with aging. However, no study has been published that provides recommendations for use in clinical practice that addresses in detail all aspects of the management of dysphagia in geriatric individuals. This study aimed to answer almost all potential questions and problems in the management of geriatric dysphagia in clinical practice. METHODS: A multidisciplinary team created this recommendation guide using the seven-step and three-round modified Delphi method via e-mail. The study included 39 experts from 29 centers in 14 cities. RESULTS: Based on the 5W and 1H method, we developed 216 detailed recommendations for older adults from the perspective of different disciplines dealing with older people. CONCLUSION: This consensus-based recommendation is a useful guide to address practical clinical questions in the diagnosis, rehabilitation, and follow-up for the management of geriatric dysphagia and also contains detailed commentary on these issues.
RESUMEN
OBJECTIVE: In our study, we aimed to evaluate the endoscopic features such as prevalence and localization of polypoid lesions determined by us using esophagogastroduodenoscopy and histopathological characteristics of biopsy specimens taken in detail. METHODS: The data of 19,560 patients undergoing upper gastrointestinal endoscopy for any reason between 2009 and 2015 in our endoscopy unit were screened retrospectively and endoscopic and histopathological findings were analyzed in detail. RESULTS: In our study, the polypoid lesion was detected in 1.60% (n=313) of 19,560 patients. The most common localization of the polypoid lesions was determined to be gastric localization (n=301, 96.2%) and antrum with a rate of 33.5% (n=105). When 272 patients in whom biopsy specimen could be taken was investigated, the most frequently seen lesion was polyp (n=115, 43.4%). Hyperplastic polyps (n=81, 29.8%) were the most frequently seen type among all polyps. In histopathological evaluation of the lesions, the prevalence rates of intestinal metaplasia (IM), surrounding tissue IM, atrophy, dysplasia, and neoplasia (adenocarcinoma, squamous cell carcinoma, gastrointestinal stromal tumor, neuroendocrine tumor, and metastatic tumor) among premalignant lesions were determined to be 16.9%, 11.2%, 4.1%, 1.1%, and 3.7%, respectively. CONCLUSION: Polypoid lesions can be seen in endoscopic investigations. In histopathological investigations, while the vast majority of these lesions are benign polyps, some of them are diagnosed as premalignant or malignant lesions. In our study, we determined malignant lesions higher than the similar studies in the literature. This condition shows how effective endoscopic procedure and histopathological evaluation are of vital importance.
RESUMEN
BACKGROUND AND AIMS: Patients with inflammatory bowel disease (IBD) are at increased risk for coronary artery disease (CAD), even after adjusting for traditional risk factors for atherosclerosis. While inflammation is widely regarded as the pathophysiologic link between IBD and CAD, the exact mechanisms are largely unknown. This study was conducted to investigate the association of lipid parameters and indices with coronary flow reserve and markers of inflammation in IBD patients. METHODS: A total of 73 patients with IBD and 26 healthy controls were enrolled. Patients in the IBD arm were either in remission or had mild disease activity. Lipid parameters, Creactive protein (CRP) and erythrocyte sedimentation rate (ESR) were analyzed using standard laboratory techniques. Coronary flow reserve (CFR) was measured using two-dimensional echocardiography. RESULTS: Both CRP and ESR were higher and CFR was significantly lower in IBD patients, but there were no differences in terms of lipid parameters or indices; however, patients with IBD and a CFR <2.0 had significantly higher triglyceride (TG) level (155.0 (80.0)â¯mg/dl vs. 108.0 (68.0)â¯mg/dl, pâ¯< 0.001) and there was a strong trend towards lower high-density lipoprotein (HDL) cholesterol (40.0 (8.5)â¯mg/dl vs. 45.0 (10.0)â¯mg/dl, pâ¯= 0.05) level in the latter group when compared to patients with a CFR ≥2.0. The atherogenic index of plasma (AIP), measured as log(TG/HDL-C) had the best predictive value for CFR in IBD group and was an independent predictor of CFR after multivariate adjustment for confounders (unstandardized coefficient: -0.75, 95% CI: (-1.13)-(-0.37)), ßâ¯= -0.41, pâ¯= <0.001). CONCLUSION: The atherogenic index of plasma is a marker for reduced CFR in IBD patients and could be useful to screen those at risk for early atherogenesis and CAD.

OBJECTIVE: There are many instruments to measure disease activity in ulcerative colitis. While determining clinical activity according to these instruments, many clinical and laboratory parameters are needed to be followed. Determination of disease activity with non-invasive and objective inflammatory indicators may be a practical and objective way. CRP/Albumin ratio (CAR) is an inflammatory marker that is considered to have prognostic value in various cancers, sepsis and acute pancreatitis. In this study, we aim to investigate diagnostic performance CAR in determining the clinical severity of ulcerative colitis. METHODS: Between November 2011 and February 2017, hospital records and follow-up cards of patients with ulcerative colitis were reviewed retrospectively. One hundred forty-nine patients were included in this study. Patient's demographic data, laboratory values, clinical disease activity, according to Truelove & Witts criteria and endoscopic activity according to the Mayo sub-score and treatments, were recorded. Diagnostic performance of CAR analyzed to determine the clinical severity. RESULTS: Of the patients included in this study, 99 (62%) were male, and 50 (38%) were female. Mean age was 45.22±14 years. When patients were grouped into remission, mild, moderate and severe disease according to disease activity, there was a statistically significant difference between CRP, CAR, erythrocyte sedimentation rate (ESR) and albumin levels (p=0.001; p<0.05). Area under the curve (AUC) values for the diagnosis of severe disease were 0.941, 0.931, 0.888 and 0.883 for CAR, CRP, ESR and albumin levels, respectively. Cut-off value to determine severe disease for CAR was 0.6 (sensitivity: 88.9%, specificity of 90.3%, positive predictive value (PPV) 85.1%, negative predictive value (NPV) 92.8%, AUC: 0.941, p<0.001). CONCLUSION: There was a significant relationship between CAR, CRP, ESR and albumin levels and clinical disease severity in patients with ulcerative colitis. CAR is a cheap and practical marker for the diagnosis of acute severe ulcerative colitis.
RESUMEN
BACKGROUND/AIMS: Hepatitis B reactivation (HBVR) is an important risk of treatment with tumor necrosis factor inhibitors (anti-TNF). While antiviral prophylaxis is recommended before treatment in HBsAg-positive patients, there is no clear approach for the follow-up or prophylactic treatment of patients with past hepatitis B virus (HBV) infection. The aim of this study was to evaluate patients with past HBV infection treated with anti-TNF for HBVR and/or HBVR-associated biochemical breakthrough. MATERIAL AND METHODS: Patients who received anti-TNF therapy and had past HBV infection (HBsAg negative, anti-HBc IgG positive, anti-HBs negative or positive) were screened and evaluated at 3-month intervals for viral and biochemical breakthrough according to a liver function test (ALT) and HBV DNA level. RESULTS: A total of 653 patients who received anti-TNF therapy were screened. Ninety of these patients had past HBV infection and had not received antiviral prophylaxis. Anti-HBs positivity and isolated anti-HBc IgG positivity were seen in 87.7% (n: 79) and 12.2% (n: 11) of these patients, respectively. No HBVR was seen in 20% (n: 18) of patients who were followed up regularly, and no HBVR-associated biochemical breakthrough was found in patients who were not followed up regularly in terms of HBV DNA level (80%, n: 72) during the follow-up period (26±16 months). CONCLUSION: The use of anti-TNF in patients with past HBV infection has a low risk for HBVR. A follow-up for the ALT and HBV DNA levels at 3-month intervals may be more reasonable than administering antiviral prophylaxis to all patients.

OBJECTIVE: An association of gastric cancer and precursor lesions with gastric xanthelasma has frequently been reported. However, the incidence of both gastric xanthelasma and gastric cancer precursor lesions increases with age. The aim of this study was to evaluate the frequency and characteristics of atrophic gastritis, intestinal metaplasia and dysplasia in patients with gastric xanthelasma compared to controls. MATERIAL AND METHODS: Cases with gastric xanthelasma endoscopically and histopathologically were included in this prospective study. The patients included in the study were compared with age- and sex-matched controls in terms of the frequency and characteristics of atrophic gastritis, intestinal metaplasia, dysplasia and cancer. RESULTS: In a series of 1892 upper endoscopies, 108 patients (5.7%) were found to have gastric xanthelasma. The average age of the patients was 61.41 ± 11.43 years. Among the patients, 58 (53.7%) were male. The frequencies of atrophic gastritis, intestinal metaplasia, dysplasia and gastric cancer in the xanthelasma group (n = 108) were 31.5, 68.5, 3.7 and 2.8%, respectively. The frequencies of atrophic gastritis, intestinal metaplasia, dysplasia and gastric cancer in the control group (n = 183) were 11.5, 31.7, 0.5 and 0.5%, respectively. Compared to the control group, the frequency of these cancer precursor lesions and the prevalence of advanced stage based on operative link on gastritis intestinal metaplasia assessment were found to be higher in the xanthelasma group (P < 0.05). CONCLUSION: Gastric xanthelasma is associated with an increased frequency of gastric precancerous lesions and should be considered an important marker.

OBJECTIVE: In this study, we aimed to investigate the presence of subclinical atherosclerosis by measuring epicardial fat thickness (EFT) and carotid intima-media thickness (cIMT), evaluate low-level inflammation with high-sensitivity C-reactive protein (hsCRP), and evaluate whether there is a relationship among lipid profile, atherogenic indices, and hsCRP with these subclinical atherosclerosis markers in patients with celiac disease (CD). METHODS: After exclusion and inclusion criteria were applied, 31 patients with CD (24 female, mean age: 39.4±12.3 years) and 32 healthy controls (21 female, mean age: 39.5±4.4 years), totally 63 cases, were recruited. Subclinical atherosclerosis was evaluated with EFT by transthoracic echocardiography and cIMT by ultrasonography. Inflammatory markers including erythrocyte sedimentation rate (ESR), hsCRP, and lipid profile were recorded. Also, atherogenic indices were calculated: Castelli risk index I and II (TG/HDL-c and LDL-c/HDL-c, respectively), atherogenic index of plasma (AIP; logarithm TG/HDL-c), non-HDL-c (TG-HDL-c), and atherogenic coefficient (AC; non-HDL-c/HDL-c). RESULTS: EFT was significantly higher in the CD group (0.49±0.10 vs. 0.49±0.09; p-value: 0.02). Although cIMT was higher in the patient group, it did not reach statistical significance (0.51±0.08, 0.47±0.08; p-value: 0.10). HDL cholesterol level was found to be significantly lower (42.0±8.8 vs. 50.0±13.7; p-value: 0.01), and the plasma atherogenic index was found to be significantly higher in the patient group (0.98±0.50 vs. 0.62±0.64; p-value: 0.02). hsCRP (3.51±3.18 vs. 1.92±1.40; p-value: 0.02) and ESR (17.2±12.8 with 9.7±3.1; p-value: 0.01) were found to be significantly higher in the CD group. Although there was a significant positive correlation between EFT and hsCRP (r: 0.453; p-value: 0.01), there was a significant negative correlation between cIMT and HDL-cholesterol (-0.339; p-value: 0.05), and a significant positive correlation with the other components of the atherogenic index was found. CONCLUSION: The risk of atherosclerosis has been increased in patients with CD. Chronic inflammation may be responsible for this increase along with atherogenic indices.
RESUMEN
OBJECTIVE: The recurring inflammation of mucosal layer of intestines is known as inflammatory bowel disease (IBD), which can be accompanied by nutritional deficiencies. The association between inflammation and coronary artery disease has been established. Coronary flow reserve (CFR), which is an established method to evaluate combined microvascular and epicardial flow of coronary arteries, can be assessed by using transthoracic echocardiography. The aim of this study was to evaluate the association of Prognostic Nutritional Index (PNI) with CFR in IBD patients. METHOD: This prospective study included 101 patients with IBD. These patients were compared to control group (n=32). PNI was calculated by using serum albumin level and lymphocyte count. CFR was assessed by using Doppler echocardiography. RESULTS: Multivariate regression analysis indicated that the presence of IBD, age (>40 years) and decreased PNI (<53.8) independently predict impairment of CFR. The area under the curve (AUC) was 75.1% (95% CI:0.664-0.838), and PNI levels were significant predictor of low CFR (p<0.001). CONCLUSION: This study showed that PNI, which is calculated using the serum level of albumin and lymphocyte count, is a strong predictor of decreased CFR in IBD patients in remission. Our findings support previous studies showing the relationship between PNI and coronary artery disease. This immunonutritional index has only two components and is easy to calculate, and inexpensive.
RESUMEN
OBJECTIVE: Morning blood pressure (BP) surge (MBPS) is defined as an excessive increase in the morning BP from the lowest systolic BP during sleep and is reported as a risk factor for cardiovascular events in current clinical studies. In this study, we aimed to investigate the relationship between MBPS and carotid intima-media thickness (C-IMT) in prehypertensive patients. PATIENTS AND METHODS: We evaluated the association between the rate of BP variation derived from ambulatory BP monitoring and C-IMT in patients with prehypertension. RESULTS: One hundred and seventy patients with prehypertension were included in the study. All office BP measurements and ambulatory 24-h, day-time, and night-time measurements were similar between each group. C-IMT [0.60 (range: 0.57-0.65) vs. 0.55 (range: 0.50-0.60) cm; P<0.001] and the mean platelet volume [8.7 (range: 7.9-9.1) vs. 7.9 (range: 7.3-8.8) fl; P=0.002] were significantly higher in the greater MBPS group than the lower group. In multivariate analysis, male sex [odds ratio (OR): 2.271, confidence interval (CI): 1.011-5.100, P=0.047], greater MBPS (OR: 8.474, CI: 3.623-19.608, P<0.001), and elevated mean platelet volume levels (OR: 3.359, CI: 1.978-5.705, P<0.001) were found to be independent predictors of greater C-IMT in prehypertensive patients. CONCLUSION: Our study suggests that greater MBPS is associated independently with C-IMT in prehypertensive patients.

This study examined the adiponectin and leptin levels and insulin resistance (IR) in patients with inflammatory bowel disease (IBD) and the associations between these factors and IBD characteristics. Fasting serum leptin, adiponectin, glucose, and insulin levels, as well as inflammatory parameters, were measured in 105 patients with IBD (49 patients with Crohn's disease [CD], 56 patients with ulcerative colitis [UC]) and 98 healthy controls [HC]. IR was evaluated using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). Disease activity and severity in patients with UC were evaluated using the Truelove-Witts index, and patients with CD were evaluated using the Crohn's Disease Activity Index. Serum adiponectin levels were found to be significantly lower in patients with CD and UC (p<0.001). Serum leptin levels were also found to be significantly higher in both the UC and CD groups (p<0.001). When HOMA-IR levels were compared, no significant difference was detected for either the CD or UC groups compared with the controls. In conclusion, it was shown that leptin levels increased and adiponectin levels decreased in patients with IBD, which is thought to be related to chronic inflammation. The effects of adipocytokines in patients with IBD with inflammatory and metabolic processes need to be investigated in further broader studies.
