Estudio de los mecanismos implicados en la génesis y evolución del asma (proyecto MEGA): creación y seguimiento a largo plazo de una cohorte de pacientes asmáticos

The general aim of this study is to create a cohort of asthma patients with varying grades of severity in order to gain greater insight into the mechanisms underlying the genesis and course of this disease.The specific objectives focus on various studies, including imaging, lung function, inflammation, and bronchial hyperresponsiveness, to determine the relevant events that characterize the asthma population, the long-term parameters that can determine changes in the severity of patients, and the treatments that influence disease progression. The study will also seek to identify the causes of exacerbations and how this affects the course of the disease.Patients will be contacted via the outpatient clinics of the 8 participating institutions under the auspices of the Spanish Respiratory Diseases Networking System (CIBER). In the inclusion visit, a standardized clinical history will be obtained, a clinical examination, including blood pressure, body mass index, complete respiratory function tests, and FENO will be performed, and the Asthma Control Test (ACT), Morisky-Green test, Asthma Quality of Life Questionnaire (Mini AQLQ), the Sino-Nasal Outcome Test 22 (SNOT-22), and the Hospital Anxiety and Depression scale (HADS) will be administered. A specific electronic database has been designed for data collection. Exhaled breath condensate, urine and blood samples will also be collected. Non-specific bronchial hyperresponsiveness testing with methacholine will be performed and an induced sputum sample will be collected at the beginning of the study and every 24 months. A skin prick test for airborne allergens and a chest CT will be performed at the beginning of the study and repeated every 5 years.     

Pediatric Cutaneous Lupus Erythematosus Treated with Pulsed Dye Laser

Pulsed dye laser (PDL) has been used in adults to treat refractory cutaneous lupus erythematosus (CLE). We report the first case of CLE in a child successfully treated with PDL.     

Programa de atención farmacéutica integrada en pacientes con enfermedades crónicas

ObjectivesTo assess whether an integrated pharmaceutical care programme (IPCP) improves clinical evolution, patient quality of life, and reduces health costs in chronic patients.Material and methodsA parallel, open, and multi-centre clinical trial of an IPCP in patients with heart failure (HF) and/or chronic obstructive pulmonary disease (COPD) in 8 different health areas in Cataluña. The intervened patient was monitored for pharmacotherapeutic evolution by hospital pharmacists, primary care physicians, and community pharmacists. Controls received normal follow-up. All patients were monitored for 12 months, with quality of life tests administered at the beginning and end of follow-up.ResultsWe had the participation of 8 different hospitals, 8 primary care centres, and 109 community pharmacies. 238 patients completed the study, with 2.9% of participants lost during the study period. There were no significant differences in terms of readmissions, visits to the doctors, or to emergency services. We detected 50 different medication-related problems (MRP) in 37 patients, with a statistically significant difference in terms of MRP between the control and treatment groups of patients with HF, and almost significant differences in COPD patients. MRP were moderate-severe in 36% of cases. MRP were avoidable in 94% of cases, and the pharmacist resolved the issue in 90% of cases. There were no differences in terms of patient quality of life or health costs between the start and end of the study.ConclusionsIntegrated pharmaceutical care programs facilitate an improvement in the quality of patient care, but electronic registries are necessary to promote communication between sections of the health care network.     

Molecular xenomonitoring and host identification of Leishmania sand fly vectors in a Mediterranean periurban wildlife park

The epidemiological cycle of zoonotic phlebotomine‐borne Leishmania infantum is a complex system in which domestic animals and wildlife interact and participate in its maintenance and transmission. In this study, we combined entomological surveillance, xenomonitoring of L. infantum and identification of host feeding sources of engorged females to investigate the potential contribution of a periurban wildlife park to leishmaniosis in neighbouring residential areas. Overall, 7,309 sand flies were collected in 111 trap‐days during the summers of 2016–2018 in an endemic area in south‐east Spain. Five different sand fly species were captured, with Phlebotomus perniciosus, the main L. infantum vector in this region, representing the most common species. Sand fly distribution was spatially heterogeneous in terms of species, sexes and female physiological stage (unfed, gravid and engorged females) and related to host distribution and management, and environmental features. None of the 602 sand flies analysed for L. infantum infection by kinetoplast real‐time PCR were positive. We used molecular tools to identify the vertebrate hosts of sand flies and identified 17 host species, mainly mammals. Human DNA was not identified in engorged sand flies. This study provides evidence that wildlife parks in south‐east Spain are ideal grounds for sand fly vectors but do not necessarily increase L. infantum infection risk to humans and dogs living in surrounding residential areas. This is probably because vectors feed mostly on non‐L. infantum competent hosts and this should be investigated for a better understanding of the contribution of wildlife parks to the local epidemiology of L. infantum.
