ABSTRACT The GIANT study collected information on patients with acute exacerbations of chronic bronchitis (AECB) and chronic obstructive pulmonary disease (COPD) and the effect of treatment with moxifloxacin.
AECB history, concomitant diseases, moxifloxacin treatment, concomitant medication, clinical symptoms and adverse events were recorded. A questionnaire at the end of treatment recorded the impact on patients' daily lives.
Among 9225 patients from eight European countries, marked variation was seen in characteristics including age, smoking history and type of exacerbation. Spirometry use was more common among chest physicians (66.7%) than GPs (15.5%). Patients with Anthonisen type 1 and 2 exacerbations had more frequent exacerbations and these patients experienced a greater impact on daily activities compared with patients with type 3 episodes. Patient symptoms improved with moxifloxacin treatment after a mean (SD) of 3.4 (1.8) days, allowing return to normal daily activities after 5.4 (4.4) days and with full recovery taking 6.5 (3.1) days.
Characteristics of patients with AECB and acute exacerbations of COPD differ among European countries. Spirometry is under-used, particularly in primary care and antibiotic treatment does not always follow current guidelines. Results confirm the efficacy of moxifloxacin in the treatment of AECB in real-life conditions.

    ABSTRACT: IntroductionWhile it is known that asthma symptoms have a very variable pattern, the general belief is that the respiratory symptoms in COPD patients usually present little or no variability. Nevertheless, COPD patients report having “bad days”. The objective of this present study was to evaluate the variability of the respiratory symptoms and their impact on the daily activities of a cohort of Spanish COPD patients.

    ABSTRACT: Chronic obstructive pulmonary disease (COPD) is a multicomponent disorder that leads to substantial disability, impaired quality of life, and increased mortality. Although the majority of COPD patients are first diagnosed and treated in primary care practices, there is comparatively little information on the management of COPD patients in primary care. A web-based pilot survey was conducted to evaluate the primary care physician's, or general practitioner's (GP's), knowledge, understanding, and management of COPD in twelve territories across the Asia-Pacific region, Africa, eastern Europe, and Latin America, using a 10-minute questionnaire comprising 20 questions and translated into the native language of each participating territory. The questionnaire was administered to a total of 600 GPs (50 from each territory) involved in the management of COPD patients and all data were collated and analyzed by an independent health care research consultant. This survey demonstrated that the GPs' understanding of COPD was variable across the territories, with large numbers of GPs having very limited knowledge of COPD and its management. A consistent finding across all territories was the underutilization of spirometry (median 26%; range 10%–48%) and reliance on X-rays (median 14%; range 5%–22%) for COPD diagnosis, whereas overuse of blood tests (unspecified) was particularly high in Russia and South Africa. Similarly, there was considerable underrecognition of the importance of exacerbation history as an important factor of COPD and its initial management in most territories (median 4%; range 0%–22%). Management of COPD was well below guideline-recommended levels in most of the regions investigated. The findings of this survey suggest there is a need for more ongoing education and information, specifically directed towards GPs outside of Europe and North America, and that global COPD guidelines appear to have limited reach and application in most of the areas studied.

    ABSTRACT: New initiatives have been introduced in Europe and the USA to encourage more rapid development of antibiotics. The need to ensure these new antibiotics can be safely used in children, and especially neonates, is important owing to high antimicrobial resistance in these patient groups. This review aims to determine what lessons can be learnt from the recent regulatory processes to speed up access to new medicines for children, focusing on antibiotics licensed for adults by the EMA since 2000. For the 11 newly approved antibiotics, 31 clinical trials enrolling children in Europe were identified. However, many of these trials included both adults and children but did not provide a subset analysis for paediatrics, limiting the relevance of their findings. Some studies have been prematurely terminated and others are apparently active but are still not yet recruiting patients. Among paediatric-specific studies, 18 evaluate safety and efficacy of new compounds, 4 are pharmacokinetic studies, but only 2 focus on neonates. Nearly all studies with an agreed Paediatric Investigation Plan have just started or are not yet recruiting. For most antibiotics, despite adult phase 3 studies being completed, with specific concerns for particular drugs already noted, it will take another 3-5 years before adequate prescribing information becomes available for paediatricians. Evidence from this review suggests that we could do better. Lessons should be learnt from paediatric antiretroviral development, with neonatal and paediatric pharmacokinetic, clinical trial and pharmacovigilance drug development programmes being run directly in parallel with adult studies-not a decade behind.
