Massive intrasplenic arterial thrombosis in a patient with chronic ITP during the development of an Evans syndrome.

Long-term safety and efficacy of eltrombopag in adults with persitent/chronic primary immune thrombocytopenia (ITP) evaluated in EXTEND study, showed a high response rate (80%) but, in the clinical safety study, it was observed that 6% of the patients presented venous and arterial thrombotic events. In addition, in the course of the disease, autoimmune hemolytic anemia (Evans syndrome, ES) may occur and could increase the risk of thrombosis. We report an interesting case of splenic rupture due to massive intrasplenic arterial thrombosis in the course of ES in a patient with chronic ITP treated with eltrombopag. The purpose of this case report is to highlight the potential increase in thrombotic risk that may involve the use of eltrombopag in hemolysis situations in patients with ITP.

Therapy-related myelodysplastic syndromes deserve specific diagnostic sub-classification and risk-stratification-an approach to classification of patients with t-MDS.

In the current World Health Organization (WHO)-classification, therapy-related myelodysplastic syndromes (t-MDS) are categorized together with therapy-related acute myeloid leukemia (AML) and t-myelodysplastic/myeloproliferative neoplasms into one subgroup independent of morphologic or prognostic features. Analyzing data of 2087 t-MDS patients from different international MDS groups to evaluate classification and prognostication tools we found that applying the WHO classification for p-MDS successfully predicts time to transformation and survival (both p < 0.001). The results regarding carefully reviewed cytogenetic data, classifications, and prognostic scores confirmed that t-MDS are similarly heterogeneous as p-MDS and therefore deserve the same careful differentiation regarding risk. As reference, these results were compared with 4593 primary MDS (p-MDS) patients represented in the International Working Group for Prognosis in MDS database (IWG-PM). Although a less favorable clinical outcome occurred in each t-MDS subset compared with p-MDS subgroups, FAB and WHO-classification, IPSS-R, and WPSS-R separated t-MDS patients into differing risk groups effectively, indicating that all established risk factors for p-MDS maintained relevance in t-MDS, with cytogenetic features having enhanced predictive power. These data strongly argue to classify t-MDS as a separate entity distinct from other WHO-classified t-myeloid neoplasms, which would enhance treatment decisions and facilitate the inclusion of t-MDS patients into clinical studies.

Is there a pressing need for improving prognostication strategies in therapy-related myelodysplastic syndromes?

Development and psychometric validation of a brief comprehensive health status assessment scale in older patients with hematological malignancies: The GAH Scale.

OBJECTIVES: The purpose of this study was to develop a new brief, comprehensive geriatric assessment scale for older patients diagnosed with different hematological malignancies, the Geriatric Assessment in Hematology (GAH scale), and to determine its psychometric properties. MATERIALS AND METHODS: The 30-item GAH scale was designed through a multi-step process to cover 8 relevant dimensions. This is an observational study conducted in 363 patients aged≥65years, newly diagnosed with different hematological malignancies (myelodysplasic syndrome/acute myeloblastic leukemia, multiple myeloma, or chronic lymphocytic leukemia), and treatment-naïve. The scale psychometric validation process included the analyses of feasibility, floor and ceiling effect, validity and reliability criteria. RESULTS: Mean time taken to complete the GAH scale was 11.9±4.7min that improved through a learning-curve effect. Almost 90% of patients completed all items, and no floor or ceiling effects were identified. Criterion validity was supported by reasonable correlations between the GAH scale dimensions and three contrast variables (global health visual analogue scale, ECOG and Karnofsky), except for comorbidities. Factor analysis (supported by the scree plot) revealed nine factors that explained almost 60% of the total variance. Moderate internal consistency reliability was found (Cronbach's α: 0.610), and test-retest was excellent (ICC coefficients, 0.695-0.928). CONCLUSION: Our study suggests that the GAH scale is a valid, internally reliable and a consistent tool to assess health status in older patients with different hematological malignancies. Future large studies should confirm whether the GAH scale may be a tool to improve clinical decision-making in older patients with hematological malignancies.

Serial intestinal endoscopic examinations of patients with persistent diarrhea after allo-SCT.

Gastrointestinal (GI) GVHD after allo-SCT is diagnosed on the basis of symptoms and findings in endoscopic mucosal biopsy specimens. However, GI symptoms often persist despite treatment and whether a second endoscopy may be helpful in determining the most suitable therapy is not established. We identified 31 patients with persistent diarrhea who underwent more than one endoscopic study. All cases underwent serial microbiological stool analysis and CMV-detecting assays on serum and biopsies. Of the 31 initial GI biopsies, 20 (64.5%) were classified as GVHD, two (6.5%) as GVHD with CMV, four (13%) as non-CMV infection, and five (16%) as normal or unspecific. The second GI biopsies were diagnostic of GVHD in nine cases (29%), GVHD simultaneously with CMV infection in four (13%), regenerative changes post-GVHD in five (16%), CMV infection in four (13%), and normal or unspecific in nine (29%). In 22 of the 31 patients (71%), the histological findings of the second/third endoscopic biopsies differed from the findings of the first endoscopy and led to a therapy change in 77%. In conclusion, serial GI endoscopies are of reliable diagnostic value and can impact on therapeutic decision-making for patients with persistent diarrhea after allo-SCT.

[Benefits of treatment to eradicate Helicobacter pylori infection in patients with ulcer at a primary care center]. / Beneficios del tratamiento erradicador de la infección por Helicobacter pylori en pacientes ulcerosos en un centro de atención primaria.

OBJECTIVES: To evaluate the clinical evolution and the use of Primary Care health resources one year after treatment to eradicate Helicobacter pylori (Hp) infection in patients with peptic ulcers and Hp infection. DESIGN: Retrospective study on the effect of an intervention. SETTING: Urban, reformed primary care centre. PATIENTS: 102 patients with peptic ulcers and Hp infection. INTERVENTION: Treatment to eradicate Hp. MEASUREMENTS AND MAIN RESULTS: a) Total medical attendance; b) attendance for dyspepsia; c) number of ulcerous outbreaks; d) medicines taken to treat dyspepsia. 79.4% of the patients treated were male. Overall mean age was 47.8 +/- 12.4. After the intervention, total attendance (from 8.3 to 6.6, p < 0.001), attendance for dyspepsia (from 3.1 to 1.1, p < 0.00001), and ulcerous outbreaks (from 1.2 to 0.06, p < 0.00001) all dropped sharply. The mean number of medicines prescribed for dyspepsia per patient fell from 1.24 to 0.43, p < 0.0001. Ranitidine prescription fell from 72.7 to 13.8 days (p < 0.001); and omeprazol from 35.1 to 12.2 days (p < 0.03). Estimated total saving per patient was 26,792 pesetas at 1998 values. CONCLUSIONS: Treatment in primary care to eradicate Hp(+) in ulcerous patients reduced the needs of attendance and the prescription of drugs for ulcers. Just in the first year this supposed a clinical benefit for these patients and important economic savings for the public health service.
