RESUMO

Extraintestinal manifestations of celiac disease (CD) are an integral part of the disease's clinical profile and, frequently, appear as the presenting feature. Given that anemia in CD may be multifactorial, increased awareness is needed on the part of treating physicians, and especially hematologists, to screen for CD. In this study, we highlight anemia as the presenting feature of CD which has remained undiagnosed for several years. In patients with a positive antibody testing or high suspicion of CD, endoscopy with a biopsy of the small intestine is performed, as it is considered the "gold standard" for diagnosing CD. Since most of the manifestations of CD are preventable or treatable with a gluten-free diet, an early diagnosis is vital for the prevention of serious and potentially lethal complications.

RESUMO

It is uncommon for the left anterior descending coronary artery to arise from the contralateral Valsalva sinus, and more of a rarity to see coexistent left main coronary artery anomaly. Our patient reported normal daily physical activity and denied further evaluation (stress test, scintigraphy) or cardiothoracic consultation. She continues to be symptom free at 1-month follow-up.

RESUMO

Panagglutination on the indirect antiglobulin test is one of the most challenging dilemmas of pretransfusion testing. It occurs when patient sera react with all red blood cells tested, that is, with both screening and identification panel cells. Two main questions must be answered. The first is to determine whether panagglutination results from the presence of autoantibody and/or alloantibody (single alloantibody or multiple alloantibodies or antibody to high-incidence antigen). The second problem is to detect the possible concomitant presence of clinically significant alloantibodies masked by panagglutination. The purpose of this mini-review is to describe the situations that can cause panagglutination and to develop algorithms which can resolve the problem. The two main points in the evaluation of panagglutination involve the assessment of the intensity of reactivity with the reagent red cells used and whether the autocontrol is positive or not. It is imperative to understand the laboratory results and the techniques available that guide the investigative process.

RESUMO

AIM: Limited data are available regarding the clinical relevance of platelet function measurements in stable patients with coronary artery disease (CAD). Our aim is to evaluate the agreement between multiple electrode aggregometry (MEA) and light transmittance aggregometry (LTA) in detecting clopidogrel low responders and their prognostic value in CAD patients with type 2 diabetes mellitus (T2DM) on dual platelet inhibition. METHODS: LTA and MEA were performed in 122 stable cardiovascular patients with T2DM. The upper quartile of patients according to maximum LTA (LTAmax) and MEA measurements were defined as clopidogrel low responders. Agreement between the two methods was evaluated by kappa statistics. We assessed the potential correlation between antiplatelet response and clinical outcome and the optimal cutoff value according to ROC analysis to predict the occurrence of major adverse cardiovascular events (MACE), during 1-year follow-up period. RESULTS: Cohen's kappa coefficients (0.214) indicated fair agreement (70.2%) between LTA and MEA. A total of 25 MACE occurred in 108 patients (23.1%). Patients with MACE had higher LTAmax than those without (57.1 ±â€¯16.5 vs 49.3 ±â€¯18.3, respectively, p = 0.023). MEA measurements were similar between patients with and without MACE (30.1 ±â€¯15.4 vs 30.6 ±â€¯20.8, respectively; p = 0.84). Multiple logistic regression showed LTAmax response as an independent predictor of death from cardiovascular causes (Odds Ratio, adjusted:0.2;0.05-0.81). ROC analysis indicated that LTAmax cutoff of 62.5% best predicted death (AUC = 0.67, sensitivity = 78%, specificity = 61.5%). CONCLUSIONS: The assessment of platelet responsiveness remains highly test-specific. Our results support the prognostic role of LTA, but not MEA testing, for death risk evaluation in stable cardiovascular T2DM patients.

RESUMO

BACKGROUND: The purpose of the present study is to present new data concerning the diagnostic efficacy of neutrophil to lymphocyte (NLR) and platelet to lymphocyte (PLR) ratios in detecting endometrial carcinoma and to summarize the existing knowledge by accumulating all the available data in the existing literature. MATERIALS AND METHODS: We retrospectively identified patients with evidence of endometrial pathology (vaginal bleeding or increased endometrial thickness) that undergone dilatation and curettage. For the meta-analysis we used the Medline, Scopus, Clinicaltrials.gov, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar databases to identify relevant articles in the field. RESULTS: In our retrospective series we identified 106 women with endometrioid endometrial carcinoma and 72 controls. PLR and NLR values were comparable among the two groups (p>.05). Eleven studies were included in the present systematic review with a total of 4168 patients. The meta-analysis included 1013 patients. PLR values were not significantly different among the two groups. On the other hand, NLR was significantly raised among patients with endometrial carcinoma (MD 0.73, 95% CI 0.01, 1.45). CONCLUSION: The findings of our meta-analysis support that NLR values are significantly elevated in patients with endometrial cancer compared to controls. Moreover, there seem to be evidence to support that both PLR and NLR values increase in patients with advanced stage disease, including positive lymph nodes, lymphovascular space involvement and distant metastases. Future studies are needed in this field to reach firm conclusions and these should specifically target patients with advanced stage disease.

RESUMO

We report the case of a 12-year-old child who was admitted to our Department, with 7 days' history of high fever and splenomegaly. His father had similar symptoms starting on the same day. A rapid test and microscopy for malaria yielded a positive result for Plasmodium vivax Antimalarial therapy was initiated. He developed methemoglobinemia treated with ascorbic acid and had uneventful recovery.

RESUMO

BACKGROUND: Our aim was to identify laboratory assays in order to assess the anticoagulant effects of dabigatran etexilate (DE). METHODS: Twenty patients with nonvalvular atrial fibrillation treated on DE (110 mg per os twice daily) and 20 on acenocoumarol were studied. Conventional coagulation tests, endogenous thrombin potential (ETP), thromboelastometry (ROTEM), epinephrine-induced light transmission aggregometry (LTA), and Hemoclot Thrombin Inhibitors (HTI) were performed in all patients. RESULTS: In ROTEM analysis, the lysis index at 60 minutes was significantly lower in patients receiving DE (P = .011). In LTA, patients on DE showed decreased aggregation compared to those on acenocoumarol, marginally insignificant (P = .068). Regarding ETP, acenocoumarol affected thrombin generation more than dabigatran (area under the curve [AUC], P < .001), while statistically significant associations were detected between dabigatran levels, as determined by the HTI assay, and almost all parameters of ETP assay (AUC, P < .001). CONCLUSION: The role of ETP in estimating anticoagulant activity of dabigatran possibly requires further research.

RESUMO

BACKGROUND: The cost-effectiveness of universal leucoreduction of blood components remains unclear. When using leucoreduced red blood cells, the decrease in the rate of febrile non-haemolytic transfusion reactions (FNHTR) is the only proven, meaningful clinical benefit, whose relationship to costs can be calculated relatively easily. The aim of this study was to evaluate the cost-effectiveness of leucoreduction in avoiding FNHTR. MATERIALS AND METHODS: Data were obtained from two large tertiary hospitals in Athens, Greece, over a 4-year period (2009-2012). The incidence of FNHTR in patients transfused with leucoreduced or non-leucodepleted red blood cells, the additional cost of leucoreduction and the cost to treat the FNHTR were estimated. The incremental cost-effectiveness ratio (ICER), which is the ratio of the change in costs to the incremental benefits of leucoreduction, was calculated. RESULTS: In total, 86,032 red blood cell units were transfused. Of these, 53,409 were leucodepleted and 32,623 were non-leucoreduced. Among patients transfused with leucodepleted units, 25 cases (0.047%) met the criteria for having a FNHTR, while in patients treated with non-leucoreduced components, 134 FNHTR were observed (0.411%). The ICER of leucoreduction was € 6,916 (i.e., the cost to prevent one case of FNHTR). CONCLUSIONS: Leucoreduction does not have a favourable cost-effectiveness ratio in relation to the occurrence of FNHTR. However, many factors, which could not be easily and accurately assessed, influence the long-term costs of transfusion. It is imperative to undertake a series of large, meticulously designed clinical studies across the entire spectrum of blood transfusion settings, to investigate most of the parameters involved.
