Background/Aims: We conducted a broad survey of 99 patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis and investigated both prognosis and outcomes. Methods: Clinical data evaluated were age, sex, patient survival, renal survival, serum albumin, serum creatinine, urinary protein, hematuria, C-reactive protein (CRP), ANCA titer, IgG and the Birmingham Vasculitis Activity Score (BVAS). Results: The patient survival rate at 6 months after onset was 84.8%, and that at 2 years after onset was 82.0%. Most deaths were within 6 months of onset. Infection accounted for 9 deaths (60.0%). Infection together with pulmonary involvement of active vasculitis accounted for 2 deaths (13.3%). Organ-specific involvement of active vasculitis alone caused 3 deaths (20.0%). Others died of cardiac events. At 1 and 3 months after onset, BVAS (p < 0.0001, p = 0.002), albumin (p = 0.006, p = 0.0004) and CRP (p = 0.04, p = 0.0002) were also associated with patient death. Conclusion: To improve the prognosis of those with ANCA-associated vasculitis, the intensity of initial treatment should be aimed at disease severity. Employing BVAS improved the ability to evaluate therapeutic responses. Finally, prescription with sulfamethoxazole-trimethoprim during the induction therapy with immunosuppressive agents may be advised.
Objective Patients in whom coronavirus disease 2019 was suspected or confirmed between January 1, 2020, and October 31, 2021, were enrolled from Japanese hospitals in this multicenter, retrospective, observational study. Methods Data on the treatment administered (including conventional and Kampo medicine) and changes in common cold-like symptoms (such as fever, cough, sputum, dyspnea, fatigue, and diarrhea) were collected from their medical records. The primary outcome was the number of days without a fever (with a body temperature <37 °C). The secondary outcomes were symptomatic relief and the worsening of illness, defined as the presence of a condition requiring oxygen inhalation. The outcomes of patients treated with and without Kampo medicine were compared. Patients We enrolled 962 patients, among whom 528 received conventional and Kampo treatment (Kampo group) and 434 received conventional treatment (non-Kampo group). Results Overall, after adjusting for the staging of COVID-19 and risk factors, there were no significant between-group differences in the symptoms or number of days being afebrile. After performing propensity score matching and restricting the included cases to those with confirmed COVID-19 who did not receive steroid administration and initiated treatment within 4 days from the onset, the risk of illness worsening was significantly lower in the Kampo group than in the non-Kampo group (odds ratio= 0.113, 95% confidence interval: 0.014-0.928, p=0.0424). Conclusion Early Kampo treatment may suppress illness worsening risk in COVID-19 cases without steroid use. Further randomized controlled studies are needed to confirm the clinical benefit of Kampo medicine for COVID-19.
Cardiovascular disease is the major cause of death in hemodialysis (HD) patients. We investigated the relation of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and left atrial volume index (LAVi) to left ventricular function in chronic HD patients. A total of 117 patients were enrolled as subjects (74 men and 43 women). Echocardiography was performed to evaluate the left atrial volume index (LAVi) and left ventricular mass index (LVMI). Diastolic left ventricular function was estimated as E/E' by tissue Doppler imaging with cardiac ultrasonography. Serum NT-proBNP was measured at the time of echocardiographic measurements. Multiple regression analysis showed that LAVi (F = 24.372, p < 0.0001) and E/E' (F = 23.473, p < 0.0116) were significant predictors for serum NT-proBNP levels, and LVMI (F = 46.807, p < 0.0001) was a best predictor for LAVi among associated factors. These findings suggest that serum NT-proBNP and LAVi are both good biomarkers for predicting the LV remodeling in chronic HD patients.
The validity of the Birmingham Vasculitis Activity Score (BVAS) as an index of disease activity and a predictor of the prognosis and outcome in patients with MPA has not yet been established in Japan. We conducted a retrospective study of the data of 73 patients with MPA who were followed up for at least 2 years. We divided the patients into two groups according to the BVAS, namely, the high-BVAS group (≥16) and the low-BVAS group (<16), and compared the clinical characteristics. In addition, the distribution of the BVAS items in the patients and the items contributing to the total score in MPA patients were analyzed. Remission was achieved in 85% of patients at 1 month. There were no significant differences in the serum CRP, creatinine (Cre), or MPO-ANCA between the high- and low-BVAS group; however, the survival time was significantly shorter (p = 0.048) and the mortality rate significantly higher in the high-BVAS group (p = 0.04). The items of the BVAS contributing to the total score were motor neuropathy, sensory neuropathy, pulmonary infiltrate, hematuria, proteinuria, Cre ≥5.6 mg/dL, hypertension, scleritis, rise in Cre by ≥30%, and myalgia. BVAS was found to be a useful tool for determining the disease activity and outcome in patients with MPA in Japan. The initial BVAS was also predictive of the mortality and survival time and can also be used as a prognostic tool; therefore, use of the tool may facilitate the selection of appropriate treatment.
