How Does Comprehensive Care Impact Life of Pediatric Patients With Hemophilia? Results From a Center in a Developing Country.

BACKGROUND: Quality of life (QoL) has been included as a marker of treatment effectiveness in pediatric patients with chronic diseases. We believe that frequent multidisciplinary interventions and patient education could lead to an improvement in QoL. AIMS: Determine the QoL and economic impact of monthly interventions in multidisciplinary treatment. MATERIALS AND METHODS: The Haemo-QoL questionnaire was applied to patients who attended the hemophilia center of the University Hospital "Dr. José Eleuterio González," Monterrey, Mexico, at the time of enrollment and 1 year later. RESULTS: Male patients between 4 and 16 years diagnosed with hemophilia were included. The score results presented are based on Haemo-QoL versions that classify patients by their age group: group 1 (4 to 7 y) and group 2 (8 to 12 y). Statistical significant improvement was observed in the overall score (sociodemographic, psychosocial, etc.) after 1 year of follow-up in both groups (P<0.05). CONCLUSIONS: Impact on the QoL of patients receiving this approach was favorable. Improvement was observed regardless of severity and in those who were already in prophylaxis, suggesting that this type of approach could be causing the improvement. Results support the application of multidisciplinary treatment as the gold standard, and it should be considered in all centers including those with limited resources.

Real-world practice of acute leukemia intrathecal chemotherapy administration: A Mexican nationwide survey.

INTRODUCTION: Intrathecal chemotherapy is a mainstay component of acute lymphoblastic leukemia treatment. In Mexico, there is a considerable practice variability in aspects, such as the manner of preparation and the administration technique. OBJECTIVE: Our objective was to describe the different techniques used for the application of ITC and review the existing recommendations in the literature. METHOD: A cross-sectional, nationwide survey study was conducted by an electronic questionnaire sent to hematologists and oncologists in Mexico. We collected demographic data, personal experience, intrathecal chemotherapy techniques, drug preparation and postprocedural conduct. RESULTS: We received 173 responses. Twenty percent had an anesthesiologist administering sedation and pain management. The platelet count considered safe was 50 × 109/L in 48% of the participants. In 77% (n = 133) of the cases, the conventional needle with stylet used was, 49% did not receive any added diluent in the intrathecal chemotherapy and only 42% were recommended to rest in a horizontal position for more than 30 min. CONCLUSION: We identified a considerable variation in the administration of intrathecal chemotherapy across the hematologists in Mexico. We discuss the implications and opportunities in reducing the variation in our setting, highlighting the unmet need to establish guidelines that should be evaluated by the Mexican professional society to produce a position paper regarding practice standardization.

CD20 expression in B-cell precursor acute lymphoblastic leukemia is common in Mexican patients and lacks a prognostic value.

Classification of acute lymphoblastic leukemia (ALL) by flow cytometric immunophenotyping characterizes the disease and delineates potential therapeutic intervention. We retrospectively analyzed CD20 expression in 143 patients with newly diagnosed precursor B-cell ALL. CD20 was observed in 61% of patients at diagnosis. There was no correlation between CD20 expression and age, white blood cell count, or cytogenetic abnormalities. Despite the fact that CD20-positive ALL patients had a tendency toward a worse outcome, there was no significant difference between patients with and without CD20 expression in 3-year overall survival 65 vs. 82% (P = 0.14), and cumulative incidence of relapse 36 vs. 18% (P = 0.3) in pediatric patients and 51 vs. 53% (P = 0.31) and 35 vs. 38% (P = 0.6) in adults, respectively. In conclusion, CD20 expression appears to be more common in Mexican patients with newly diagnosed precursor B-cell ALL higher than in Caucasian populations and lacks prognostic value.
