Background: cHL patients with relapsed/refractory (RR) disease who relapse after or are ineligible for autologous stem cell transplantation have a poor prognosis. Recently, the anti-PD1 monoclonal antibodies nivolumab and pembrolizumab were approved by the FDA (May 2016 and March 2017, respectively) as treatment options for RR cHL patients.Aims: This study aims to describe real-world patient characteristics and HRU (hospitalizations and outpatient [OP] visits) among patients with RR cHL receiving pembrolizumab or nivolumab in the US. Methods: A retrospective database analysis was conducted using Symphony Health's Patient Integrated Dataverse ® (07/2014-06/2018). The date of the first dispensing or administration of pembrolizumab or nivolumab was termed the index date. Patients with ≥12 months of clinical activity prior to the index date, ≥1 hospitalization or ≥2 OP encounters with an ICD-9/10-CM diagnosis of cHL prior to the index date, no diagnosis of nodular lymphocyte-predominant HL, and ≥18 years of age were included. Baseline patient characteristics were assessed in the 12 months prior to the index date. HRU was evaluated over the entire follow-up period, from the index date to the end of clinical activity or data availability. Crude rates of hospitalizations and OP visits were calculated as number of events divided by person-time of observation, expressed as rate per person per year (PPPY), to account for varying durations of observation across patients. Mean and median hospital length of stay (LOS) were reported. Results: Among cHL patients, 92 received pembrolizumab and 225 received nivolumab. The mean age was 59 and 53 years among those treated with pembrolizumab and nivolumab, of whom 40% and 44% were female, respectively. Corresponding median (IQR) follow-up periods were 214 (92-325) and 249 (126-443) days. Mean baseline Quan-Charlson comorbidity index score for pembrolizumab and nivolumab patients was 4.9 and 4.0; 18% and 14% had depressive disorders, and 16% and 8% had substance-related and addictive disorders, respectively. Of pembrolizumab patients, 7% had received nivolumab and 26% brentuximab vedotin (BV). Of nivolumab patients, none had received pembrolizumab, 40% received BV, and 2% received ibrutinib. Pembrolizumab and nivolumab patients had an average of 1.5 and 1.4 all-cause hospitalizations during the baseline period, respectively, while the corresponding rate of all-cause hospitalizations during follow-up was 0.9 and 1.3 PPPY with an associated mean [median] LOS of 3.1 [1.5] and 4.2 [2] days (Figure). The rate of all-cause OP visits during follow-up was 36.4 and 35.5 PPPY for pembrolizumab and nivolumab patients, respectively. The rate of cHL-related hospitalizations during follow-up was 0.1 PPPY for pembrolizumab patients, with a mean [median] LOS of 4.7 [1] days, and 0.4 PPPY for nivolumab patients, with a mean [median] LOS of 7.4 [4] days.
Summary/Conclusion:This real-world descriptive study attempts to provide an early assessment of nivolumab and pembrolizumab user profiles and resourc...
Öz Huzursuz bacak sendromu (HBS) bacaklarda hareket etme dürtüsü ile kendini gösteren, şikayetlerin istirahatte arttığı, bacaklarda rahatsızlık veren duyumlar ile karakterize uyku ilişkili bir hastalık olarak tanımlanmış nörolojik duyusal-motor bir bozukluktur. Hastalığın primer (idiyopatik) HBS ve sekonder (semptomatik) HBS olmak üzere iki formu vardır. İdiyopatik form genetik ve kaynağı bilinmeyen etiyolojik nedenleri içerirken, sekonder formun çok çeşitli sebepleri olabilir. Sekonder HBS'nin etiyolojik sebepleri değerlendirildiğinde %43' ünün anemi ile birlikte veya anemi olmaksızın sistemik demir eksikliği ilişkili olduğu tespit edilmiştir. Bu yazıda; son 2 yılda 8 kez tam kan bağışında bulunan ve ferritin düşüklüğüne atfedilen sekonder HBS' lu bir olgumuzu sunduk.
