[Asthma control in adult Algerian patients. Comparison with other North African and Middle-East countries]. / Contrôle de l'asthme chez l'adulte en Algérie. Comparaison avec les autres pays d'Afrique du Nord et du Moyen Orient.

INTRODUCTION: Lack of recent data on asthma control in Algeria led to this study whose results were compared with those of the same study conducted in the Middle East and North Africa (MENA). METHOD: This cross-sectional epidemiological study was performed in adults who had been diagnosed with asthma for at least one year and without exacerbation within the last 4 weeks. Asthma control was assessed using the 2012 Global Initiative for Asthma (GINA) criteria and the Asthma control test (ACT) questionnaire. RESULTS: We studied 984 patients mainly managed by specialist physicians; 61% female, mean age 45 years, body mass index 27kg/m2, active smokers 2%. Medication was prescribed in 92% with 78% receiving inhaled corticosteroids alone or with add-on therapies. Good adherence was observed in 27%. Asthma control was observed in 34.6% vs. 28.6% in other countries (P < 0.001). Low level of education, absence of medical insurance, lack of physical exercise, and-long duration of the disease were significantly associated with uncontrolled asthma. CONCLUSION: Poor control of asthma is still observed in Algeria despite a high level of specialist involvement. Except for adherence, known predictive factors of poor asthma control have been observed. Quality improvement training of health care professionals and patient education are probably the main issues to be addressed.

A trial comparing local pain after subcutaneous injection of epoetin-beta versus darbepoetin-alpha in healthy volunteers.

BACKGROUND: The aim of this study was to compare local pain experienced with subcutaneous (s.c.) injection of epoetin-beta vs. darbepoetin-alpha. METHODS: 40 healthy volunteers were enrolled into this single-blind, crossover study. After receiving an injection of placebo, individuals were randomized to receive s.c. injections of epoetin-beta 6,000 IU (0.3 ml) or darbepoetin-alpha 30 mg (0.3 ml), with a 1-week washout period between injections. Local pain was evaluated using a Visual Analog Scale (VAS) and a 6-item Verbal Rating Scale (VRS) immediately after (T0) and 1 h after injection (T1). RESULTS: The respective mean (standard deviation) and median (range) VAS values at T0 were 1.2 (1.7) and 0.5 (0.0 - 6.9) for epoetin-beta vs. 2.8 (2.4) and 1.9 (0.0 - 9.0) for darbepoetin-alpha (p < 0.0001). At T0, VRS scores demonstrated that 51% of individuals experienced no pain after epoetin- injection compared with 16% of those receiving darbepoetin-alpha. The percentage of individuals perceiving moderate or important pain was significantly greater with darbepoetin-alpha (38%) compared with epoetin-beta (5%, p = 0.0005) and placebo (14%). Pain evaluation at T1 showed no difference between treatment groups. Local tolerance was excellent except for a small hematoma with epoetin- at T1 and with darbepoetin-alpha at T0 which persisted at T1. CONCLUSION: In healthy volunteers, s.c. injection of epoetin-beta was significantly less painful than with darbepoetin-alpha and comparable with placebo. No significant pain was apparent at T1 in any group.

Multicentre, phase II study evaluating capecitabine monotherapy in patients with anthracycline- and taxane-pretreated metastatic breast cancer.

Treating patients with anthracycline- and taxane-pretreated metastatic breast cancer (MBC) represents a significant challenge to oncologists. The tumour-activated oral fluoropyrimidine, capecitabine, is the only treatment approved for these patients. Our study evaluated the efficacy, safety and impact on quality of life (QOL) of capecitabine in this setting. Patients (n=126) with anthracycline- and taxane-pretreated metastatic breast cancer received capecitabine 1250 mg/m(2) twice daily, days 1-14, followed by a 7-day rest period. Median time to progression was 4.9 months (95% Confidence Interval (CI): 4.0-6.4). Thirty-five patients (28%) achieved an objective response (95% CI: 20-36%), including five (4%) complete responses. Median overall survival was 15.2 months (95% CI: 13.5-19.6 months). Capecitabine demonstrated a favourable safety profile, with a low incidence of treatment-related grade 3/4 adverse events. The most common adverse events were hand-foot syndrome and gastrointestinal effects. QOL assessment showed that capecitabine treatment was associated with an increase in mean Global Health Score. Capecitabine is active, well tolerated and improves the QOL of patients with anthracycline- and taxane-pretreated metastatic breast cancer. Based on the consistently high activity demonstrated in clinical trials, capecitabine has become the reference treatment in this setting.

Rituximab (anti-CD20 monoclonal antibody) as single first-line therapy for patients with follicular lymphoma with a low tumor burden: clinical and molecular evaluation.

The clinical activity of rituximab, a chimeric monoclonal antibody which binds to the CD20 antigen, was evaluated as a single first-line therapy for patients with follicular non-Hodgkin lymphoma (NHL). Fifty patients with follicular CD20(+) NHL and a low tumor burden were analyzed for clinical and molecular responses. They received 4 weekly infusions of rituximab at a dose of 375 mg/m(2). The response rate a month after treatment (day 50) was 36 of 49 (73%), with 10 patients in complete remission, 3 patients in complete remission/unconfirmed, and 23 patients in partial remission. Ten patients had stable disease, and the disease progressed in 3 patients. One of 13 (8%) patients in complete remission, 9 of 23 (39%) patients in partial remission, and 5 of 10 (50%) patients with stable disease exhibited disease progression during the first year. Within the study population, 32 patients were initially informative for polymerase chain reaction (PCR) data on bcl-2-J(H) rearrangement. On day 50, 17 of 30 patients (57%) were negative for bcl-2-J(H) rearrangement in peripheral blood, and 9 of 29 (31%) were negative in bone marrow; a significant association was observed between molecular and clinical responses (P <.0001). At month 12, 16 of 26 patients (62%) were PCR negative in peripheral blood. These results indicate that early molecular responses can be sustained for up to 12 months and that this response is highly correlated with progression-free survival. Rituximab has a high clinical activity and a low toxicity and induces a high complete molecular response rate in patients with follicular lymphoma and a low tumor burden.
