Treatment compliance in cystic fibrosis patients with chronic Pseudomonas aeruginosa infection treated with tobramycin inhalation powder : The FREE study

Background: A high treatment burden with nebulised therapies in cystic fibrosis (CF) patients is the major limitation for treatment compliance; moreover, studies on treatment compliance with inhaled antibiotics are limited. This study assessed compliance to TOBI\uae Podhaler\u2122 (TIP) treatment in CF patients with chronic Pseudomonas aeruginosa (Pa) infections in a real-world setting using the Italian Treatment Adherence CF Questionnaire (ITA-CFq). Methods: This longitudinal, multicentre, cohort study included 2 follow-up (FU) visits: FU-1 at 3-months\ub115-days from the baseline visit and FU-2 at the end of third TIP cycle (or 6-months after enrolment, whichever occurred first). The effect of TIP on quality-of-life (QoL) and treatment satisfaction were evaluated using Cystic Fibrosis Questionnaire-Revised (CFQ-R) and Treatment Satisfaction Questionnaire for Medication (TSQM), respectively. Overall compliance to treatments was assessed using ITA-CFq. Results: Eighty-two patients (mean age, 24.8 \ub1 7.9 years), including 22 paediatric patients (age, <18 years), were enrolled in the study; 56 (68.3%) patients, including 17 paediatric patients, completed the study. At baseline, the mean compliance score to aerosol antibiotic treatment was 7.8 \ub1 3.2; upon introducing TIP, the compliance score improved to 9.4 \ub1 1.2 at the FU-1 and thereafter remained stable at 9.5 \ub1 1.2. TSQM was higher for the convenience domain (74.2 \ub1 17.1 at enrolment and slightly improved to 77.8 \ub1 15.9 at FU-2) following TIP initiation. No substantial effect of TIP was observed on the QoL when measured using the revised CFQ-R. The safety profile was in line with previous findings. Conclusion: TIP was convenient to use and led to improved treatment adherence in CF patients with chronic Pa-infection

An overview of international literature from cystic fibrosis registries. Part 4: Update 2011.

A total of 53 national cystic fibrosis (CF) patient registry studies published between July 2008 and November 2011 have been reviewed, focusing on the following topics: CF epidemiology, nutrition, microbiology, clinical complications, factors influencing diagnosis and lung disease, effects of socioeconomic status, therapeutic strategy evaluation, clinical trial methodology. The studies describe the clinical characteristics of CF patients, the incidence and prevalence of disease and role of gender gap, as well as the influence of socioeconomic status and environmental factors on clinical outcomes, covering a variety of countries and ethnic groups. Original observations describe patients as they get older, with special reference to the adult presentation of CF and long-term survival. Methodological aspects are discussed, covering the design of clinical trials, survival analysis, auxometry, measures of quality of life, follow up of lung disease, predictability of disease progression and life expectancy. Microbiology studies have investigated the role of selected pathogens, such as Burkholderia species and MRSA. Pulmonary exacerbations are discussed both as a factor influencing morbidity and an endpoint in clinical trials. Finally, some studies give insights on complications, such as CF-related diabetes and hemoptysis, and emerging problems, such as chronic nephropathy

Toxicological aspects of cannabinoid, pesticide and metal levels detected in light Cannabis inflorescences grown in Italy

Recently, the cultivation of light Cannabis, with a total THC content less than 0.6%, has been encouraged due to its industrial and therapeutic potential. This has increased the consumption of hemp for both smoking purposes and food preparation. Even so, Cannabis inflorescences are not subject to EU regulations and standards provided for food and tobacco products. A study was carried out on thirty-one inflorescences samples, collected in different Italian regions, in order to determine cannabinoids, pesticides and metals and to evaluate the exposure of consumers to contaminants and ensure a safe consumption. Contents of THC were always below 0.5%, while CBD ranged between 0.3 and 8.64%. The determination of 154 pesticides showed that 87% of the samples contained fungicides and insecticides in the range 0.01-185 μg/g. The most found are spynosad and cyprodinil. The concentration of metals ranged from 1 to more than 100 μg/g, and As, Cd, Co, Cr, Hg, Cu, Mo, Ni and V exceeded the regulatory US limits for inhaled Cannabis products, while Pb exceeded them for both oral and inhaled products. These contaminants are intrinsically toxic and may affect public health. Actions are needed to establish regulatory measures and reduce the adverse effects caused by contaminants in Cannabis
