The main objective of this study was to compare health-related quality of life (HRQOL) of primary immune thrombocytopenia (pITP) patients with that of general population, overall, and by patient group (i.e., newly diagnosed, persistent, and chronic patients). Fatigue was also investigated as a secondary objective. Overall, 424 adult patients were enrolled in a multicenter observational study and the control group consisted of a representative sample from the general population. Propensity score matching plus further multivariate linear regression adjustment was used to compare HRQOL outcomes between pITP patients and general population. Mean age of patients was 54 years. Of those with HRQOL assessment, 99 patients (23.6%) were newly diagnosed, 53 (12.6%) were persistent, and 268 (63.8%) were chronic pITP patients. Comparison by patient group versus their respective peers in the general population revealed greater impairments in persistent pITP patients. Persistent pITP patients reported clinically meaningful impairments in physical functioning (-15; 95% CI -24.1 to -5.8; P = 0.002), social functioning (-15.3; 95% CI -25.5 to -5.1; P = 0.004), role physical (-28.4; 95% CI -43.1 to -13.7; P

Higher fatigue severity was associated with lower physical and mental HRQOL outcomes. Our findings suggest that the burden of the disease and treatment might depend on the disease phase and that persistent pITP patients are the most vulnerable subgroup. Am. J.

Several studies have shown the existence of an association between celiac disease (CD) and non-Hodgkin's lymphoma (NHL). Our aim was to evaluate the usefulness of the serum anti-tissue transglutaminase (anti-tTG) antibody assay in screening for CD in consecutive NHL patients. In all, 80 consecutive patients (median age 61 years) with a new diagnosis of NHL were included. To compare the frequency of CD and of positive results for the anti-tTG assay, we enrolled 500 blood donors. In all patients serum anti-tTG was determined with two different ELISA: one based on tTG from guinea pig (gp-tTG) and the other based on human recombinant t-TG (h-tTG) as the antigens. Serum anti-endomysial antibodies (EmA) were also assayed. Subjects with positive serum EmA and/or anti-tTG underwent intestinal biopsy for histology study, HLA-DQ phenotype determination, and serum anti-gliadin (AGA) assay. Eight of 80 (10%) NHL patients were positive for anti-tTG ELISA—two of these exclusively for anti-gp-tTG and six for anti-h-tTG (7.5%). None of the 80 NHL patients were positive for serum EmA. The frequency of anti-tTG positivity in the blood donor controls was 2/500 (0.4%), significantly lower than that observed in the NHL patients (P < 0.0001). Both these blood donors were found to have CD. Only in one anti-h-tTG-positive NHL patient was there intestinal mucosa atrophy, and follow-up confirmed a CD diagnosis (CD frequency in NHL patients is 1.2%; versus blood donors: P = 0.4). In all the other seven anti-tTG-positive NHL patients a normal intestinal architecture was found, although, inflammatory infiltration of the lamina propria was observed in four patients. No anti-tTG-positive NHL patients, including the subject diagnosed as having CD, had a family history of CD, and all had normal weight and no signs of malabsorption. Anti-tTG false positive results were associated with a higher frequency of serum autoantibody positivity and T-cell type NHL. In conclusion, NHL patients the anti-tTG assay often gives discordant data with the EmA assay, with a high frequency of anti-tTG false positive results for CD diagnosis.

Introduction: Very little is known about health-related quality of life (HRQOL) of patients diagnosed with primary Immune Thrombocytopenia (pITP). Also, the paucity of available data mainly stems from patients enrolled in randomized controlled trials thus limiting generalizability of findings to patients routinely seen in real world practice. Aim: The main objective of this study is to compare HRQOL of pITP patients with that of their peers from the general population and to investigate whether HRQOL differences exist among those classified as (Rodeghiero et al, Blood. 2009 Mar 12;113(11):2386-93): newly diagnosed, persistent and chronic pITP patients. Methods: Adult patients with pITP were consecutively enrolled, regardless of therapy, in 25 centers. All patients were invited by their treating physicians in the hospital. Consenting patients were requested to complete a battery of patient-reported outcome (PRO) questionnaires. The primary HRQOL outcome measure was the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). It consists of 36 items covering eight generic health status/QoL domains: physical functioning (PF), role limitations due to physical health (RP), bodily pain (BP), general health perceptions (GH), vitality (VT), social functioning (SF), role limitations due to emotional problems (RE), and mental health (MH). To minimize possible bias in comparisons of pITP patients HRQOL outcomes to general population norms, a propensity score matching approach plus further regression adjustment was adopted to select the best possible case-control pairs. The group of potential controls was a representative sample of 1997 adults without the disease from a previous study which provided SF-36 population norms. Controls from these data were matched to pITP patients by an optimal nearest-neighbour matching algorithm based on age, sex, education, and geographic area. Multiple linear regression analyses were performed on the matched dataset to compute adjusted mean differences (α=0.05), using selected a priori key HRQOL confounders as covariates: age, sex, education, geographic area, and marital status. Effect sizes were computed and clinical significance of mean scores SF-36 differences was also estimated. Results: Out of 424 patients invited to participate, 420 returned the questionnaires (99% compliance). At study participation, mean age of patients was 54 years (range 18-89) with the majority being women (N=264, 64%). The mean platelet count at diagnosis was 27.6 x109/L and the mean platelet count at last medical visit, before the HRQOL assessment, was 119 x109/L. Two-hundred twenty patients (50%) had at least 1 comorbidity. At the time of HRQOL assessment there were 82%, 64% and 44% of patients receiving active treatments, respectively in the newly diagnosed, persistent and chronic pITP group. Splenectomy was performed in 8% and 22% of the persistent and chronic pITP patients, respectively. No statistically significant differences existed among the three disease groups with regard to age, gender and presence of comorbidity. When compared with their peers in the general population, worse statistically significant outcomes (P Conclusions: Persistent pITP patients are those experiencing the most important limitations in both physical and mental HRQOL domains with respect to their peers from the general population. This information can help physicians to pay special attention to this patient group in their daily clinical practice.

We have read with interest the paper of Huhn et al on rituximab therapy of patients with B-cell chronic lymphocytic leukemia (CLL).[1][1] Seven of 28 heavily pretreated patients showed a partial remission (NCI criteria), lasting for a median of 20 weeks. Huhn et al conclude that rituximab as a
