Background Nephrotic syndrome is associated with an increased risk of venous thromboembolism (VTE). However, the risk factors of VTE in nephrotic syndrome, other than hypoalbuminemia and severe proteinuria, are not well established. Therefore we aimed to investigate the risk factors of VTE in patients with nephrotic syndrome. Methods This retrospective cohort study used data from a Japanese nationwide claims database. We identified patients ≥18 years of age hospitalized with nephrotic syndrome. Through multivariable logistic regression, we determined the risk factors of VTE in patients with nephrotic syndrome during hospitalization. Results Of the 7473 hospitalized patients with nephrotic syndrome without VTE, 221 (3.0%) developed VTE. In the VTE group, 14 (6.3%), 11 (5.0%) and 198 (89.6%) patients developed pulmonary embolism, renal vein thrombosis and deep vein thrombosis, respectively. We found that female sex {odds ratio [OR] 1.39 [95% confidence interval (CI) 1.05–1.85]}, body mass index (BMI) ≥30 [OR 2.01 (95% CI 1.35–2.99)], acute kidney injury [AKI; OR 1.67 (95% CI 1.07–2.62)], sepsis [OR 2.85 (95% CI 1.37–5.93)], lupus nephritis [OR 3.64 (95% CI 1.58–8.37)] and intravenous corticosteroids use [OR 2.40 (95% CI 1.52–3.80)] were associated with a significantly higher risk of developing VTE. Conclusions In patients with nephrotic syndrome, female sex, BMI ≥30, AKI, sepsis, lupus nephritis and intravenous corticosteroid use may help evaluate the risk of VTE.

Background Septic shock is a common and life-threatening condition that requires intensive care. Intensive care units (ICUs) in Japan are classified into ICUs and high-dependency care units (HDUs), depending on presence of full-time certified intensivists and the number of assigned nurses. Compared with other developed countries, there are fewer intensive care beds and certified intensivists in Japan; therefore, non-intensivists often treat patients with septic shock in HDUs. It is unknown where we should treat patients with septic shock because no studies have compared the clinical outcomes between ICU and HDU treatment. This study aimed to elucidate which units should admit patients with septic shock by comparing mortality data and resource use between ICU and HDU admissions. Methods In this retrospective cohort study, we used a nationwide Japanese administrative database to identify adult patients with septic shock who were admitted to ICUs or HDUs between January 2010 and February 2021. The patients were divided into two groups, based on admittance to ICU or HDU on the day of hospitalization. The primary outcome was 30-day all-cause mortality adjusted for covariates using Cox regression analyses; the secondary outcomes were the length of ICU or HDU stay and length of hospital stay. Results Of the 10,818 eligible hospitalizations for septic shock, 6584 were in the ICU group, and 4234 were in the HDU group. Cox regression analyses revealed that patients admitted to the ICUs had lower 30-day mortality (adjusted hazard ratio: 0.89; 95% confidence interval: 0.83–0.96; P = 0.005). Linear regression analyses showed no significant difference in hospital length of stay or ICU or HDU length of stay. Conclusions An association was observed between ICU admission and lower 30-day mortality in patients with septic shock. These findings could provide essential insights for building a more appropriate treatment system.
