The conv. HD group. In addition, there were little but considerable variations in each RAF709 site therapy groups regarding the time period from hospital admission to initiation of chemotherapy or extracorporeal therapy (Table 1). In the HCO-HD group, chemotherapy and extracorporeal remedy had been initiated almost simultaneously. Inside the conv. HD group, dialysis was began in median 4 days ahead of chemotherapy initiation.OutcomesThe HCO-HD group showed a drastically greater price of renal recovery compared with the conv. HD group (64.3 vs. 29.four , odds ratio [OR] four.3, 95 self-assurance interval [CI] 1.3?four.6, p = 0.014), as shown by the Kaplan-Meier curves (Fig 2A). In addition, a sustained sFLC response was observed more typically in HCO-HD sufferers (83.three ) compared with conv. HD sufferers (29.four ) (p = 0.007) (Table 2). Moreover, there was no important difference in renal recovery with PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/211
regard to which HCO filter was used (HCO-1100 vs. Theralite; data not shown). The typical duration of sFLC expected to attain values <1000 mg/l was 14.5 days in the HCO-HD group, compared with 36 days in the conv. HD group. The corresponding regression curves are shown in Fig 2B. Of course, we cannot exclude an additional effect of the varying antimyeloma therapy on this parameter. Regardless, a sustained decline of sFLC values to <1000 mg/l was associated with a higher rate of renal recovery (S1 Fig). Specifically, patients with a sustained sFLC reduction had a renal recovery rate of 70 (21 of 30 patients), compared with a rate of 37.9 (11 of 29 patients) among patients with sFLC values !1000 mg/dl (OR = 3.8, 95 CI 1.3?1.2, p = 0.015). The associated regression curve of sFLC is shown in S1 Fig. Predictors of a sustained sFLC decrease are presented in S2 Table. The corresponding one-year overall survival of patients with renal recovery was 78.1 , compared with 44.4 of dialysis-dependent patients (p = 0.117; data not shown). Among the survivors free of dialysis, the median eGFR (CKD-EPI) at day 90 was lower in the HCO-HD group than in the conv. HD group (48 and 100 ml/min/1.73 m2, respectively, p = 0.035). The rate of renal recovery in the HCO group (64 ) was comparable to that in previous reports.[10?2,19,20] Furthermore, we found that HCO-HD was independently associated with a greater sFLC decline and a higher rate of renal recovery than conv. HD, as shown by two different statistical multivariate approaches. Almost a decade ago, Hutchison and coworkers discovered that protein-leaking dialysis filters (HCO filters) allowed the removal of immunoglobulin sFLC in large amounts. Subsequent studies utilized HCO filters and found that renal recovery in the myeloma kidney depends on the early reduction of sFLC and is associated with a significant survival advantage. [10?2] In these and other studies, the rate of renal recovery from dialysis-dependent AKI secondary to MM was consistently >60 .[10?2,19,20] Importantly, the big majority of individuals with renal function recovery soon after combination therapy with chemotherapy and HCO-HD did not call for additional dialysis throughout long-term follow-up. Therefore, early reduction of sFLC is currently broadly accepted as a significant therapeutic purpose in dialysis-dependent AKI secondary to MM. On the other hand, mainly because none with the published research integrated a handle group of patients treated with conv. HD (i.e., with no extracorporeal sFLC removal), the added advantage of HCO-HD as an add-on remedy to common chemotherapy alone has not b.
