Abstract Background Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease with a complex progression of many clinical presentations, and clinically important deterioration (CID) has been proposed in the Western studies as a composite endpoint of disease progression. The aim of this study was to investigate the relationships between 1-year CID and the following long-term clinical outcomes in Japanese patients with COPD who have been reported to have different characteristics compared to the Westerners. Methods Among Japanese patients with COPD enrolled in the Hokkaido COPD cohort study, 259 patients who did not drop out within the first year were analyzed in this study. Two definitions of CID were used. Definition 1 comprised ≥ 100 mL decrease in forced expiratory volume in 1 s (FEV1), ≥ 4-unit increase in St George’s Respiratory Questionnaire (SGRQ) score from baseline, or moderate or severe exacerbation. For Definition 2, the thresholds for the FEV1 and SGRQ score components were doubled. The presence of CID was evaluated within the first year from enrollment, and analyzed the association of the presence of CID with following 4-year risk of exacerbations and 9-year mortality. Results Patients with CID using Definition 1, but not any single CID component, during the first year had a significantly worse mortality compared with those without CID. Patients with CID using Definition 2 showed a similar trend on mortality, and had a shorter exacerbation-free survival compared with those without CID. Conclusions Adoption of CID is a beneficial and useful way for the assessment of long-term disease progression and clinical outcomes even in Japanese population with COPD. The definition of CID might be optimized according to the characteristics of COPD population and the observation period for CID.

The outcomes of hemorrhagic fever with renal syndrome (HFRS) were analyzed in 55 patients who were under the supervision of a physician – infectious within one year after the disease. This issue has been studied in more detail by the example of Hantaan virus infection in the Far East, the effects of Puumala infection aren’t well understood, vigilance among physicians concerning the formation of chronic kidney disease in patients is lacking. However, it is proved that the peculiarities of the clinical course of HFRS are caused by a specific serotype of the virus. It is revealed that the leading clinical manifestation in patients in early reconvalescence period of HFRS was astheno vegetative syndrome. Long-term prognosis of patients with HFRS, isn’t always favorable, it may be associated with prolonged disorders of the kidneys. Renal pathology includes lumbar – pain, eyelid swelling, dysuric phenomena, polyuria, nycturia, proteinuria, hematuria, cylindruria, reposotory. It is established that the disease is accompanied by a prolonged dysfunction of the nervous system, cardiovascular system, hepato-biliary system, this suggests the possibility of development of chronic pathology of different organs and the need for surveillance of HFRS patients, not only the infectious, but the nephrologist, cardiologist, neurologist.
