The Stratified Population Screening of Hereditary Hemorrhagic Telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant multisystemic vascular disease with a wordwide prevalence of 1:5000-1:10000. We introduce our algorithm for the stratified population screening of HHT. Probands are selected from the consecutive hospital database review for HHT (I7800) and recurrent epistaxis (R0400) and the review of patient records referred by family practicioners. A proportion of probands might be de novo diagnosed with HHT in the 10-year study period. The checkup of probands consists of physical examination, arteriovenous malformation exploration and and genetic testing (ACVRL1 and ENG sequence analysis). The family screening of HHT consists of physical examination and screening for the family-specific mutation of each at-risk individual, and furthermore, arteriovenous malformation exploration in individuals with suspected/definite HHT and/or carrying the mutation. Twenty-five definite HHT patients were explored: 7 of them by the I7800 review, 1 by the R0400 review, 3 were de novo diagnosed, and the remaining 14 were explored by the systematic family screening. Considering the 20 patients alive at the end of the study period and the unavailable 5 potential HHT patients and 12 at-risk family members, the HHT prevalence is estimated to be 1:6090-1:11267 in our study area, implying our algorithm's effectivity in the stratified population screening of HHT.

Effectiveness of the Combination of Rituximab and Standard Chemotherapeutic Regimens in Previously Untreated Patients with Chronic Lymphocytic Leukaemia in Real-Life: Results from a Noninterventional Study (CILI Study).

Chronic lymphocytic leukemia (CLL) is one of the most common haematological malignancies exhibiting remarkable heterogeneity in clinical course. Rituximab added to standard chemotherapy has been proven to increase response rate and eventually survival among previously untreated CLL patients. CILI was an open-label, non-randomized, single arm, multicentric, observational study aimed to collect real-life effectiveness data for rituximab used according to the current label in combination with standard chemotherapy in previously untreated CLL patients. Overall response rates (ORR) in the entire study population as well as in various subgroups were estimated. Adverse events were recorded during the entire course of the study. A total number of 150 patients were enrolled by 15 Hungarian study sites. Out of these, 82 patients received 6 cycles of rituximab containing treatment. Overall response rates of 88.24% (CI95%: 81.6-93.12%) and 94.59% (CI95%: 86.73-98.51%) were recorded in the intent-to-treat (ITT) and per-protocol (PP) populations, respectively. In both study populations, somewhat higher ORR was observed in patients aged ≥65 years. Subgroups defined according to either chromosomal aberrations (presence of 11q and 17p deletions) showed apparently high ORRs, though these rates were most probably biased by low patient numbers. 144 adverse events were reported during the study, of which 15 AEs were considered to be related to the administration of rituximab. Analyses of the efficacy variables have revealed comparable results to those previously reported by controlled clinical trials.
