[Use of antiviral substances in respiratory tract diseases].

Viral infections are an important factor in pathogenesis of symptom aggravation in COPD, which is usually accompanied by immunological system insufficiency, i.e. local immunity. Respiratory syncytial viruses are of vital importance. The paper presents possibilities of using active antiviral substances: amantadine, remantadine, ribavirine, zanamivir preparation. Substances isolated from natural resources have also been mentioned.

Human metapneumovirus and lower respiratory tract disease in otherwise healthy infants and children.

BACKGROUND: We sought to determine the role of human metapneumovirus in lower respiratory tract illness in previously healthy infants and children. METHODS: We tested nasal-wash specimens, obtained over a 25-year period from otherwise healthy children presenting with acute respiratory tract illness, for human metapneumovirus. RESULTS: A viral cause other than human metapneumovirus was determined for 279 of 687 visits for acute lower respiratory tract illness (41 percent) by 463 children in a population of 2009 infants and children prospectively seen from 1976 to 2001. There were 408 visits for lower respiratory tract illness by 321 children for which no cause was identified. Of these 321 children, specimens from 248 were available. Forty-nine of these 248 specimens (20 percent) contained human metapneumovirus RNA or viable virus. Thus, 20 percent of all previously virus-negative lower respiratory tract illnesses were attributable to human metapneumovirus, which means that 12 percent of all lower respiratory tract illnesses in this cohort were most likely due to this virus. The mean age of human metapneumovirus-infected children was 11.6 months, the male:female ratio was 1.8:1, 78 percent of illnesses occurred between December and April, and the hospitalization rate was 2 percent. The virus was associated with bronchiolitis in 59 percent of cases, pneumonia in 8 percent, croup in 18 percent, and an exacerbation of asthma in 14 percent. We also detected human metapneumovirus in 15 percent of samples from 261 patients with upper respiratory tract infection but in only 1 of 86 samples from asymptomatic children. CONCLUSIONS: Human metapneumovirus infection is a leading cause of respiratory tract infection in the first years of life, with a spectrum of disease similar to that of respiratory syncytial virus.

[The value of studies of quality of life in chronic respiratory tract diseases in the framework of holistic medicine].

Quality of Life (QOL) is a new area of research evaluating the psychical, functional and psychological components of human life. According to current understanding of health issues the measurement of morbidity or mortality does not estimate the health status and describe the influence of illness on human life. The theoretical framework of Health Related Quality of Life is largely based on a multidimensional perspective of human as physical, psychological and social functioning and well-being, along the WHO definition of health. QOL assessment could be carried out using different psychological methods. There are several questionnaires developed to assess the quality of life in patients. The measurement instruments are generic (used in wide range of health related issues), domain specific (concerning some important outcome such as social support, coping), and disease specific which are used to assess patients with particular health problems. QOL assessment could be used as the measurements in pharmacoeconomics and clinical trials. Polish QOL Initiative Group produce Polish version of existing questionnaires--for example The Asthma Quality of Life Questionnaire was registered in Polish language version. Quality of Life researches facilitate doctors to understand patient's perceiving of the health state and help them to live a fulfilling life.
