Background:N-terminal pro-B-type natriuretic peptide (NT-proBNP) has been used for risk stratification in heart failure or acute coronary syndrome, but the beyond 5-year predictive value of NT-proBNP for stroke remains an unsettled issue in Asian patients. The aim of the present study was to clarify this point.Methods and Results:We followed 1,198 participants (33.4% men; mean age, 60.5±11.1 years old) in the Japanese general population for a median of 13.0 years. A first stroke occurred in 93 participants. Referencing previous reports, we stratified participants according to NT-proBNP 30.0, 55.0, and 125.0 pg/mL. Using the NT-proBNP <30.0 pg/mL group as a reference, adjusted HR for stroke (95% CI) in the NT-proBNP 30.0–54.9-pg/mL, 55.0–124.9-pg/mL, and ≥125.0-pg/mL groups were 1.92 (0.94–3.94), 1.77 (0.85–3.66), and 1.99 (0.86–4.61), respectively. With the maximum follow-up period set at 5 years, the hazard ratio of the NT-proBNP≥125.0-pg/mL group compared with the <30.0-pg/mL group increased significantly (HR, 4.51; 95% CI: 1.03–19.85). On extension of the maximum follow-up period, however, the association between NT-proBNP and stroke risk weakened.Conclusions:NT-proBNP was significantly associated with an elevated stroke risk. Given, however, that the predictive power decreased with the number of years after NT-proBNP measurement, NT-proBNP should be re-evaluated periodically in Asian patients.

Background:N-terminal pro-B-type natriuretic peptide (NT-proBNP) is known to increase in heart failure patients. Given that no reports have described the association between NT-proBNP and chronic kidney disease (CKD) incidence in Asian populations, we investigated this association in the Japanese population.Methods and Results:We followed up 867 participants without CKD from the general population of Ohasama, Japan. We defined CKD as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2and/or proteinuria. In accordance with previous studies, the participants were classified into 4 groups according to NT-proBNP level (<30.0, 30.0–54.9, 55.0–124.9, and ≥125.0 pg/mL). The Cox model was applied to assess adjusted hazard ratios (HR) for CKD incidence after full adjustment including baseline eGFR. Participant mean age was 59.1 years, and 587 (67.7%) were women. During the mean follow-up period of 9.7 years, 177 participants developed CKD. When the group with NT-proBNP <30.0 pg/mL was used as the reference, adjusted HR for CKD incidence in the 30.0–54.9, 55.0–124.9, and ≥125.0 pg/mL groups were 1.34 (95% CI: 0.90–2.01), 1.25 (95% CI: 0.81–1.92), and 1.83 (95% CI: 1.05–3.18), respectively.Conclusions:NT-proBNP can be significantly predictive for CKD incidence in Asian populations.

Patients with renal failure undergoing hemodialysis often have muscle cramps during and after the dialysis therapy. Muscle cramps are defined as the sudden onset of a prolonged involuntary muscle contraction accompanied with severe pain, resulting in early termination of a HD session and inadequate dialysis. The etiology of the cramps is unknown and effective anti-cramp medicine is not available. We have hypothesized that water-soluble vitamins are deficient in HD patients. Accordingly, we administrated biotin to 14 patients who had frequent muscle cramps during HD sessions. Oral administration of 1 mg/day biotin promptly reduced the onset and the severity of cramps in 12 patients both during and after HD. Then, the plasma biotin levels were measured by an enzyme-linked immunosorbent assay method (ELISA) in HD patients, including 14 patients with cramps and 13 patients without cramps, and 11 healthy volunteers. Plasma biotin levels were elevated in 27 HD patients at baseline compared with healthy volunteers [451 (377 - 649) vs. 224 (148 - 308) ng/l, median (lower-upper quartiles); p < 0.0001]. Unexpectedly, among the 14 cramp patients, the biotin levels were significantly higher in biotin-ineffective 7 patients than biotin-effective 7 patients [1,064 (710 - 1,187) vs. 445 (359 - 476) ng/l; p < 0.001]. Thus, the biotins measured by ELISA may consist of not only intact biotin but also its metabolites that do not function as a vitamin. In conclusion, biotin administration is one choice to relieve HD patients from muscle cramps regardless of their elevated plasma biotin levels.
