Usefulness of assessment of the Clinical Frailty Scale and the Dementia Assessment Sheet for Community-based Integrated Care System 21-items at the time of initiation of maintenance hemodialysis in older patients with chronic kidney disease.

INTRODUCTION: We examined whether the Clinical Frailty Scale (CFS), a widely adopted tool for stratifying the degree of frailty, and the Dementia Assessment Sheet for Community-based Integrated Care System 21-items (DASC-21), a simple tool for simultaneous assessment of impaired cognition and impaired ADL, at the time of initiation of hemodialysis is useful tool of older patients for the outcome and prognosis. METHODS: Data for 101 patients aged 75 years or older (mean age, 84.3 years) with ESRD who were initiated on hemodialysis and could be followed up for a period of 6 months were reviewed. RESULTS: The 6-month survival curves showed a significantly higher number of deaths in the frailty (CFS≥5) group than in the normal to vulnerable (CFS<5) group (p<0.01). The CFS level was also significantly higher (6.5±1.5) in patients who died within 6 months of dialysis initiation as compared with that (4.6±1.7) in patients who survived (p<0.01). On the other hand, the total score of DASC-21 was related to need for inpatient maintenance dialysis (p<0.01). The total score on the DASC-21 were found as showing significant correlations with the CFS level. The IADL outside the home was identified in the DASC-21 sub-analyses as being correlated with CFS. CONCLUSIONS: The CFS and the DASC-21 appeared to be a useful predictive tool of outcome and prognosis for older patients being initiated on hemodialysis. Assessment by the CFS or the DASC-21 might be useful for selecting the renal replacement therapy by shared decision-making and for advance care planning.

Anti-glomerular basement membrane disease developing 3 years after the development of Sweet syndrome and 1 year after the development of anti-neutrophil cytoplasmic antibody-associated vasculitis: a case report.

A 73-year-old Japanese woman, with a history of Sweet syndrome diagnosed 3 years earlier and anti-myeloperoxidase (MPO) antibody anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis diagnosed 1 year earlier, presented with an episode of rapidly progressive glomerulonephritis (RPGN) with anti-glomerular basement membrane (GBM) disease. At the time of diagnosis of the ANCA-associated vasculitis 1 year earlier, serological testing yielded a negative result for anti-GBM antibody. However, at the present visit, serology for anti-MPO antibody was negative, while that for anti-GBM antibody was positive. This is the first report of anti-GBM disease developing sequentially after Sweet syndrome and ANCA-associated vasculitis. This case may provide clues to the potential immunological links among these three distinct conditions.

[Fatal primary influenza virus pneumonia in a patient with secondary myelofibrosis during ruxolitinib therapy].

In recent years, fatal cases of primary influenza virus pneumonia have been rare. A 67-year-old woman with secondary myelofibrosis, who had been diagnosed with polycythemia vera 25 years prior, died of primary influenza virus pneumonia. She was immunocompromised due to the underlying disease and ruxolitinib therapy, but she was not vaccinated against influenza. She might have caught the flu from an infected family member. This case reminds us of the importance of infection control measures such as preventing familial infection during ruxolitinib therapy in severely immunocompromised patients.
