“…The J-CKD-DB is a multicenter, automatically extracted comprehensive database of patients with CKD from 21 university hospitals in Japan (UMIN trial number, UMIN000026272) [23,24]. The inclusion criteria for the J-CKD-DB are as follows: 1) age �18 years; 2) proteinuria �1+ (dipstick test) and/or eGFR <60 ml/min/1.73 m 2 , where eGFR is calculated using the Japanese eGFR equation: eGFR (ml/min/1.73 m 2 ) = 194 × serum creatinine value -1.094 × age -0.287 (× 0.739 [for women]) [26].…”

“…In this study, we performed an observational cross-sectional investigation. To exclude most patients with acute kidney injury, we omitted inpatients from this analysis [24]. We identified 39,121 adult outpatients with at least one measurement of serum creatinine in seven university hospitals from January 1, 2014 to December 31, 2014.…”

“…The Japan Chronic Kidney Disease Database (J-CKD-DB) is a large-scale, nationwide comprehensive clinical database of patients with CKD based on electronic health records data from participating university hospitals [23,24]. Using a standardized method for information exchange (Standardized Structured Medical Information eXchange; SS-MIX2) [25], the J-CKD-DB efficiently compiles clinical data of patients with CKD across hospitals, regardless of differences in electronic health records systems.…”

Aims Pulmonary congestion, reduced cardiac output, neurohumoral factor activation, and decreased renal function associated with decreased cardiac function may have various effects on haemograms. The relationship between these factors and haemograms in patients with heart failure has not been sufficiently investigated. Recently, it was suggested that the lungs are an important site for platelet (Plt) biosynthesis and that it is necessary to study the relationship between pulmonary congestion and Plt count in heart failure in detail. In this study, we examined the relationship between various haemodynamic indicators and haemograms in detail using statistical analyses. Methods and results A total of 345 patients who underwent cardiac catheterization for the evaluation of cardiac function between 1 January 2015 and 31 December 2020 were included in the study. Haemodynamic indices, including left ventricular end‐diastolic pressure (LVEDP) and cardiac index (CI), were measured. Plasma noradrenaline (Nor) concentration, estimated glomerular filtration rate (eGFR), white blood cell (WBC) count, haemoglobin (Hb) level, and Plt count were measured using blood samples collected at the same time. Structural equation modelling (SEM) was used to examine the relationship between LVEDP, CI, plasma Nor concentration, eGFR, WBC count, Hb level, and Plt count. Bayesian inference using SEM was performed for Plt count. A total of 345 patients (mean age: 66.0 ± 13.2 years) were included in this study, and 251 (73%) patients were men. After simple and multiple regression analyses, path diagrams were drawn and analysed using SEM. LVEDP showed a significant negative relationship with Plt count (standardized estimate: −0.129, P = 0.015), and CI showed a significant negative relationship with Hb level (standardized estimate: −0.263, P < 0.001). Plasma Nor concentration showed a significant positive relationship with WBC count (standardized estimate: 0.165, P = 0.003) and Plt count (standardized estimate: 0.198, P < 0.001). The eGFR had a significant positive relationship with Hb level (standardized estimate: 0.274, P < 0.001). Bayesian inference using SEM revealed no relationship between LVEDP and Hb level or WBC count but a significant negative relationship between LVEDP and Plt count. Conclusions LVEDP, CI, plasma Nor concentration, and eGFR were related to WBC count, Hb level, and Plt count in patients with heart failure. There was a strong relationship between elevated LVEDP and decreased Plt count, suggesting that pressure overload on the lungs may interfere with the function of the lung as a site of Plt biosynthesis.

Disproportionality Analysis on Hypothyroidism With Roxadustat Using the Japanese Adverse Drug Event Database

Hypoxia‐inducible factor prolyl‐hydroxylase inhibitor (HIF‐PHI) is a novel agent for the treatment of renal anemia. HIF‐PHI increases endogenous erythropoietin production by inhibiting the degradation of an erythropoietin transcription factor. Although beneficial effects are expected from HIF‐PHI, its novel mechanism raises concerns regarding the risk of potential adverse events. The cases of hypothyroidism, which had not been reported in clinical trials, were reported after the administration of roxadustat in a real‐world setting. However, the effects of HIF‐PHIs on thyroid function have not yet been fully evaluated. This study aimed to assess the clinical impact of HIF‐PHIs on thyroid function using the Japanese Adverse Drug Event Report database, a spontaneous reporting system in Japan, because HIF‐PHIs were made available in Japan before they were available in other countries. Although a disproportionality signal for hypothyroidism was detected with roxadustat (reporting odds ratio [ROR]:22.1, 95% confidence interval [CI]:18.3‐26.7, no signals were detected with another HIF‐PHI, daprodustat (ROR:1.3, 95%CI:0.3‐5.4), and epoetin beta pegol (ROR:1.2, 95%CI:0.5‐2.7). Signals of hypothyroidism due to roxadustat were also detected regardless of age or sex. Approximately 50% of hypothyroidism cases were reported within 50 days of starting roxadustat use. These results indicate that roxadustat use may be related to the development of hypothyroidism. The need for monitoring of thyroid function should be alerted during roxadustat administration regardless of age or sex.
