The Evaluation of Left Ventricular Functions with Tissue Doppler Echocardiography in Adults with Celiac Disease

Background/Aim:

The aim of this study was to investigate the effects of celiac disease on cardiac functions using tissue Doppler echocardiography (TDE).

Patients and Methods:

The study included 30 patients with celiac disease (CD) and 30 healthy volunteers. Echocardiographic examinations were assessed by conventional echocardiography and tissue Doppler imaging. The peak systolic velocity (S^''m), early diastolic myocardial peak velocity (E^''m), late diastolic myocardial peak velocity (A^''m), E^''m/A^''m ratio, myocardial precontraction time (PCT^''m), myocardial contraction time (CT^''m), and myocardial isovolumetric relaxation time (IVRT^''m), E to E^''m ratio were measured.

Results:

In pulsed wave Doppler echocardiography, mitral late diastolic flow (A) velocity and E to E^''m ratio were significantly higher (P = 0.02 and P = 0,017), E/A ratio was significantly lower (P = 0.008) and IVRT was significantly prolonged (P = 0.014) in patients with CD. In TDE, S^''m, E^''m, and E^''m/A^''m ratio were significantly lower, IVRT^''m was longer (P = 0.009) from septal mitral annulus and S^''m, E^''m, E^''m/A^''m ratio were significantly lower, PCT^''m, PCT/ET ratio, IVRT^''m were longer, and MPI was higher from lateral mitral annulus in celiac group than controls.

Conclusion:

Our study confirms that patients with CD have impaired diastolic function. More importantly, we also demonstrated an impairment of myocardial systolic function in patients with CD by TDE. We recommend using TDE in addition to conventional echocardiography parameters for the cardiovascular risk assessment of patients with CD.     

Adipokines and ghrelin in gastric cancer cachexia

AIM： To investigate the roles of the adipocytokines, ghrelin and leptin in gastric cancer cachexia.
METHODS： Resistin, ghrelin, leptin, adiponectin, insulin and insulin-like growth factor （IGF-Ⅰ）, were measured in 30 healthy subjects, and 60 gastric cancer patients of which 30 suffered from cancerinduced cachexia and 30 served as a control group. The relationships between hormones, body mass index （BMI） loss ratio, age, gender, and Glasgow Prognostic Score （GPS） were investigated.
RESULTS： Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients （P 〈 0.05）. Ghrelin, resistin, leptin, adiponectin and IGF- Ⅰ, showed a significant correlation with BMI loss ratio and GPS （P 〈 0.05）. A strong correlation was seen between GPS and BMI loss （R = -0.570, P 〈 0.0001）. Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin, resistin, leptin and IGF-Ⅰ （P 〈 0.05）. Existence of an important significant relationship between resistin and insulin resistance was also noted.
CONCLUSION： These results showed that serum ghrelin, leptin, adiponectin, and IGF-Ⅰ play important roles in cachexia-related gastric cancers. No relationship was found between resistin and cancer cachexia. Also, because of the correlation between these parameters and GPS, these parameters might be used as a predictor factor.     

The mediating role of C-reactive protein and handgrip strength between obesity and walking limitation

OBJECTIVES: To study the association between different obesity indicators and walking limitation and to examine the role of C‐reactive protein (CRP) and handgrip strength in that association. DESIGN: A cross‐sectional, population‐based study. SETTING: The Health 2000 Survey with a representative sample of the Finnish population. PARTICIPANTS: Subjects aged 55 and older with complete data on body composition, CRP, handgrip strength, and walking limitation (N=2,208). MEASUREMENTS: Body composition, anthropometrics, CRP, medical conditions, handgrip strength, and maximal walking speed were measured in the health examination. Walking limitation was defined as maximal walking speed less than 1.2 m/s or difficulty walking half a kilometer. RESULTS: The two highest quartiles of body fat percentage and CRP and the two lowest quartiles of handgrip strength were all significantly associated with greater risk of walking limitation when chronic diseases and other covariates were taken into account. In addition, high CRP and low handgrip strength partially explained the association between high body fat percentage and walking limitation, but the risk of walking limitation remained significantly greater in persons in the two highest quartiles than in those in the lowest quartile of body fat percentage (odds ratio (OR)=1.75, 95% confidence interval (CI)=1.19–2.57 and OR=2.80, 95% CI 1.89–4.16). The prevalence of walking limitation was much higher in persons who simultaneously had high body fat percentage and low handgrip strength (61%) than in those with a combination of low body fat percentage and high handgrip strength (7%). Using body mass index and waist circumference as indicators of obesity yielded similar results as body fat percentage. CONCLUSION: Low‐grade inflammation and muscle strength may partially mediate the association between obesity and walking limitation. Longitudinal studies and intervention trials are needed to verify this pathway.     

Cytomegalovirus colitis in a patient with Behcet’s disease receiving tumor necrosis factor alpha inhibitory treatment

Anti-tumor necrosis factor alpha （TNF-α） inhibitors are effective in the treatment of various inflammatory rheumatic conditions. Increased risks of serious infections are the major issues concerning the long-term safety of these agents. We present a case of a young male Behcet’s patient whose disease was complicated by cytomegalovirus （CMV） colitis. Colitis started 10 d after the third Infliximab dose and responded to the cessation of TNF blocking treatment and administration of ganciclovir. Tumor necrosis factor alpha and interferon gamma act at several levels in combating viral infections.CMV infections should be kept in mind and included in the differential diagnosis of severe gastrointestinal symptoms in patients receiving anti-TNF agents.     

Impact of Anti-Aggregant,Anti-Coagulant and Non-Steroidal Anti-Inflammatory Drugs on Hospital Outcomes in Patients with Peptic Ulcer Bleeding

Background/Aims:

There are a limited number of studies including the impact of antiplatelet drugs use on hospital outcomes for nonvariceal upper gastrointestinal bleeding. The aim of this study was to determine the effect of anti-aggregant, anti-coagulant and non-steroidal anti-inflammatory drugs upon hospital outcomes in patients with peptic ulcer bleeding.

Materials and Methods:

The patients under treatment with antiaggregant, anticoagulant or non-steroidal anti-inflammatory drugs were categorized as exposed group (n = 118) and the patients who were not taking any of these drugs were categorized as non-exposed group (n = 81). We analyzed the data of drug intake, comorbid disease, blood transfusion, duration of hospital stay, Blatchford/total Rockall score and diagnosis of patients.

Results:

In total, 199 patients were included. Of these 59.3% (exposed group) were taking drugs. The patients in exposed group were significantly older than those in non-exposed group (62.9 ± 17.3 years; 55.5 ± 19.3 years, P = 0.005, respectively). Mean number of red blood cell units transfused (2.21 ± 1.51; 2.05 ± 1.87, P = 0.5), duration of hospital stay (3.46 ± 2.80 days; 3.20 ± 2.30 days, P = 0.532) and gastric ulcer rate (33% vs 23.4%, P = 0.172) were higher in exposed group than in non-exposed group but the differences were not statistically significant. Total Rockall and Blatchford scores of the patients were significantly higher in exposed group than in non-exposed group (3.46 ± 1.72 vs 2.94 ± 1.87, P = 0.045; 10.29 ± 3.15 vs 9.31 ± 3.40, P = 0.038).

Conclusıon:

Our study has shown that anticoagulants, antiaggregants and nonsteroidal anti-inflammatory drugs do not effect duration of hospital stay, red blood cell transfusion requirement and rebleeding for peptic ulcer bleeding.
