- Do markers of eosinophil activation differ in their ability to detect subjects with atopy or bronchial hyper-responsiveness (BHR)? Comparisons of serum levels of eosinophil peroxidase (S-EPO), of eosinophil cationic protein (S-ECP) and the blood eosinophil count (B-Eos) have been made between 154 subjects aged 20-44 years, participating in the European Community Respiratory Health Survey in Uppsala, Sweden. Subjects with atopy had significantly higher levels of S-EPO and S-ECP than those without atopy (P <0 center dot 001). Subjects with BHR had significantly higher levels of S-EPO (P <0 center dot 001) and B-Eos (P <0 center dot 01) than subjects without BHR. Persons reporting asthma-related symptoms had significantly higher levels of S-EPO and B-Eos than subjects without such symptoms (P <0 center dot 001 and P <0 center dot 01, respectively). Asthma symptom score correlated significantly to S-EPO (r = 0 center dot 26, P <0 center dot 01), S-ECP (r = 0 center dot 20, P <0 center dot 05) and B-Eos (r = 0 center dot 18, P <0 center dot 05). Finally, S-EPO was significantly more sensitive than S-ECP for detecting subjects with BHR (P <0 center dot 05) and significantly more sensitive than B-Eos for detecting both subjects with BHR and subjects with a combination of atopy and BHR (P <0 center dot 05). It is concluded that S-EPO is a promising marker with a higher sensitivity for BHR than S-ECP or B-Eos. Further studies are needed to define the value of S-EPO when following disease activity.

- The aim of this study was to investigate the relationship between the effect of emergency treatment and inflammatory markers in patients with acute exacerbations of obstructive pulmonary disease, especially with respect to smoking history. We investigated 50 unselected patients with acute bronchial obstruction. Blood, urine and sputum samples were taken and analysed for eosinophil and neutrophil markers. The patients were observed for at least 2 h and recordings of forced expiratory volume in 1 s (FEV1) were taken. They were re-examined after 1 and 4 weeks. The absolute levels of inflammatory markers did not differ significantly between non- or short-term smokers (< or = 5 pack-years) and long-term smokers (> 5 pack-years) with the exception of myeloperoxidase in serum (S-MPO), which was higher in long-term smokers. The patients with higher levels of eosinophil markers before emergency treatment experienced a greater improvement in lung function. In non- or short-term smokers this relationship was found in blood and urine, whereas in long-term smokers it was seen in sputum. No correlation was found between neutrophil markers and changes in lung function. We conclude that patients with obstructive pulmonary disease with acute exacerbations and high levels of eosinophil markers respond well to treatment.

Sleep, psychological symptoms and quality of life in patients undergoing coronary artery bypass grafting
- 1999

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this thesis sleep, psychological symptoms and quality of life (Qol) in patients undergoing coronary artery bypass grafting (CABG) at the University Hospital in Linköping were evaluated. Interviews and 24-hour polysomnography were performed prior to surgery, immediately after surgery and again at one month, with a six-month-follow-up mailed questionnaire. Habitual sleep was evaluated using the Uppsala Sleep Inventory questionnaire and a diary the recorded mornings. The Spielberger State of Anxiety Scale and the Zung's Self-rating Depression Scale were used to measure anxiety and depression, respectively. Physical functional capacity was assessed according to the New York Heart Association's (NYHA) classes and Qol, with the Nottingham Health Profile instrument (NHP).A retrospective evaluation of nurse's documentation about sleep was also performed. In addition, the quality and quantity of sleep were assessed before surgery and in the immediate postoperative period in a pilot study, with a one-month follow-up interview. The results indicated disturbed sleep, and changes in behaviour and mental state after surgery due to fragmented sleep, pain and anxiety.Forty-four patients were examined prior to surgery. The results showed that almost two-fifths experienced too little sleep habitually and 50 % had a combination of at least two sleep problems. Poorer health, higher level of anxiety and increased difficulties maintaining sleep (DMS) were consistent with significantly longer sleep latency, increased fragmented sleep, and reduced stages 3 and 4 and RIM sleep measured by polysomnography. The level of Qol on the NBP was significantly associated with objectively measured sleep.In the immediate period following CABG there is a changed distribution of sleep, with a reduction of nocturnal sleep duration and an increase in daytime sleep, which had almost returned to preoperative values one month after surgery. Qol was significantly improved six months after surgery compared to before surgery.It was noted that patients with a more anxiety prone reactivity during six months following CABG had significantly more sleep disturbances, reduced energy and functional physical capacity, and lower quality of life, compared to those without such reactivity. Significantly more sleep disturbances, reduced energy and lower quality of life were more prominent among those with sadness/depression or cognitive/behavioural fatigue as reactions to sleep loss. A higher degree of cognitive/behavioural fatigue and dysphoria reactions were associated with a higher NYHA class.In conclusion, patients with coronary artery disease have poor quantity and quality of sleep. Increased psychological symptoms in patients with CAD prior to surgery were associated with greater symptoms six months after surgery. Physical functional capacity and quality of life were significantly improved six months after surgery.
