[Correlation between the SF-8 health status questionnaire and JRQLQ in patients with Japanese cedar pollinosis].

BACKGROUND: It is reported that the health-related quality of life (HRQL) is an important outcome in the Japanese Cedar Pollinosis (JCP) treatment. In Japan, the disease-specific Japan Rhino-conjunctivitis Quality of Life Questionnaire (JRQLQ) and the generic SF-36 Health Survey (SF-36) has been used. The aim of this study is to investigate more profitable QOL by using both the disease-specific questionnaire and the non-disease-specific questionnaire together. METHODS: 411 patients with JCP who visited 10 ENT clinics in Osaka from March 14 to March 26 (peak pollen season) in 2005 were questioned, and 240 patients were engaged in this study as subjects. In this study, the QOL scores were evaluated using the JRQLQ and SF-8 Health Survey (Japanese Version), a new, even shorter generic health survey. RESULTS: Using factor analysis and the correlation matrix, we showed that the disease-specific and the general health instrument covered a different half the total measurable HRQL. There was some correlation between the SF-8 items with the JRQLQ domains. There was little correlation between the SF-8 items and symptom scores, while, there was high correlation between the JRQLQ and symptom scores. The "Usual daily activities" domain in the JRQLQ correlated with any rhinoconjunctivitis symptoms. CONCLUSION: Both JRQLQ and SF-8 can be used to assess the quality of life of patients with JCP. Each instrument measures the aspects of the HRQL that hardly overlaps. For an assessment of the HRQL in JCP that is complete and responsive both instruments should be employed together.

[Quality of life in patients with Japanese cedar pollinosis: using the SF-8 health status questionnaire (Japanese version)].

BACKGROUND: The number of patients with Japanese cedar pollinosis (JCP) is increasing, and now, has extended up to about 15% of the Japanese. It is reported that the QOL is an important outcome in the JCP treatment. This study aimed to evaluate the QOL in patients with JCP by means of the SF-8 Health Survey (Japanese Version), a new, even shorter generic health survey. METHODS: 411 patients with JCP who visited 10 ENT clinics in Osaka from March 14 to March 26 (peak pollen season) were questioned, and 204 patients without any treatments in this season were engaged in this study as subjects. In this study, the QOL scores were evaluated using the SF-8. This is an 8-item version of the SF-36 that yields a comparable 8-dimension health profile and comparable estimates of summary scores for the physical and mental components of health. RESULTS: The QOL score depressed in the patients with JCP compared with healthy subjects (Japanese national norms). Both Mental Component Score (MCS) and Physical Component Score (PCS) scores decreased more in females than in males. In females, MCS were significantly lower than national norms. The older the patients were, the lower PCS scores were showed. The severity of nasal symptoms influenced the PCS scores. CONCLUSION: These results showed the tendency similar to the early studies using SF-36 questionnaire. The sensitivity of SF-8 in the individual is not better than that of other specific QOL questionnaires, but SF-8 can be answered in a short time compared with other questionnaires including SF-36. We suggested that SF-8 become a useful questionnaire in the future.

[Case of primary Sjögren's syndrome with hypereosinophilia and elevation of serum IgE: measurements of serum IL-4, IL-5 and the IgG subclass].

A 62-year-old man admitted to our hospital because of dry eyes and thirst. On admission, his bilateral parotid and submandibular glands were swelling. Laboratory data revealed severe eosinophilia (3309/microl), elevated serum IgE (1821IU/dl) and hypergammaglobulinemia (IgG 6049 mg/dl). Interstitial pneumonia and renal dysfunction were present. He was diagnosed with Sjögren's syndrome (SjS) according to the European criteria. After the initiation of the therapy with 30 mg of prednisolone, all abnormal findings including salivation ameliorated promptly. In the absence of any other obvious causes of eosinophilia and elevation of serum IgE, these findings might be associated with SjS itself. Moreover, both serum IL-5 and IgG4 levels were elevated in this patient, suggesting that Th2 type cytokines were dominant. Elevation of serum IgE and IgG4, and hypereosinophilia were likely to be reactive. To our knowledge, there have been no reports of these cytokines and of IgG subclass in such patients. We propose the existence of Th2-type-cytokine-dominant subtype of SjS.

[Self-care for pollinosis of cedar and cypress--from a questionnaire survey].

For patients with pollinosis, self-care is important as well as medical care. In this study, we investigated the real situation of patients with pollinosis-how they manage their symptoms. A questionnaire-based examination was conducted among 488 patients who visited National Osaka-Minami hospital and Sano ENT clinic. The onset of pollen dispersion occurred 17th Feb. 34.6% of patients visited before the onset of pollen dispersion. 45.5% of them had a checkup for allergens. 84.8% of them utilized pollen information. 41.4% of them did self-care. The rate of patients who utilized pollen information and did self-care was higher in female compared with male. The rate of those who did self-care was significantly higher in the patients who visited before pollen dispersion, who had a checkup for allergens, who utilized pollen information, compared with the patients did not. It is necessary to show the information of self-care as well as pollen, and suggest the importance of self-care against pollen allergens.

Measurement of quality of life during different clinical phases of Japanese cedar pollinosis.

OBJECTIVE: To assess Quality of Life (QOL) scores in patients with Japanese cedar (Cryptomeria japonica, CJ) pollinosis. METHODS: QOL was measured intraseasonally and extraseasonally in patients (n = 69) using the Medical Outcomes Study Short-Form Health Survey, and compared with healthy control subjects (n = 50). The differences in intraseasonal QOL scores between short and long disease duration groups were studied. The relation of intraseasonal QOL scores to nose symptoms was evaluated using Spearman's rank correlation. RESULTS: Significant decrease was observed in two of eight QOL items in intraseasonal measurements of patients. These QOL impairments improved extraseasonally. Scores for emotional problems in patients with long disease duration were less impaired than those with short disease duration. QOL scores in patients correlated poorly with the severity of nasal symptom. CONCLUSIONS: This is the first study to report QOL impairment in CJ pollinosis. Based on the findings long disease duration may improve emotional problems, and the correlation between disease severity and QOL is low.
