RÉSUMÉ
AIMS: This retrospective claims data study characterized real-world treatment patterns, healthcare resource utilization (HCRU), and costs in patients with metastatic urothelial carcinoma (mUC) in Germany. MATERIALS AND METHODS: Continuously insured adults with incident mUC diagnosis (=index; ICD-10: C65-C68/C77-C79) in 2015-2019 were identified from two German claims databases. Patients who received first-line (1 L) treatment within 12 months of index were divided into three mutually exclusive sub-cohorts: platinum-based chemotherapy (PB-CT), non-PB-CT, and immunotherapy (IO). Patient characteristics were assessed during a 24-month baseline period; treatments, HCRU, and costs (of the health insurance fund) per patient-year (ppy) were described during 12-month follow-up. RESULTS: We identified 3,226 patients with mUC (mean age, 73.8 years; male, 70.8%; mean Elixhauser Comorbidity Index, 17.6); 1,286 (39.9%) received 1 L treatment within 12 months of index. Of these, 825 (64.2%) received PB-CT, 322 (25.0%) non-PB-CT, and 139 (10.8%) IO. On average, treated patients had 5.1 hospitalizations ppy. Most UC-related hospitalizations ppy were observed in the PB-CT cohort (5.8), followed by the non-PB-CT (4.2) and IO (2.3) cohorts. Mean UC-related hospitalization costs ppy were 22,218 in the treated cohort, 24,294 in PB-CT, 19,079 in IO, and 18,530 in non-PB-CT cohorts. Cancer-related prescription costs ppy averaged 6,323 in treated patients, and 25,955 in IO, 4,318 in non-PB-CT, and 4,270 in PB-CT cohorts. LIMITATIONS: We recognized limitations in our study's sample selection due to unavailable mUC disease status data. We addressed this through an upstream feasibility study conducted in consultation with clinical experts to determine a suitable proxy. Proxies were also used to delineate treatment lines, switches, and discontinuations due to data absence. Furthermore, due to data restrictions, collective dataset analysis was not possible, prompting a meta-analysis for pooled results. CONCLUSIONS: The study shows that mUC is associated with significant HCRU and costs across different types of 1 L systemic therapy.

Aim: This study assessed real-world treatment in patients with metastatic urothelial carcinoma (mUC) in Germany. Materials & methods: Patients diagnosed with mUC from 2015 to 2019 were identified in two claims databases: AOK PLUS and GWQ. Results: 3226 patients with mUC were analyzed; 1286 (39.9%) received systemic treatment within 12 months of diagnosis (platinum-based chemotherapy: 64.2%). Factors associated with receiving treatment were: younger age, male sex, less comorbidity and recent diagnosis. In AOK PLUS and GWQ populations, unadjusted median overall survival (interquartile range) from diagnosis in treated patients was 13.7 (6.8-32.9) and 13.8 (7.1-41.7) months, and in untreated patients was 3.0 (1.2-10.8) and 3.6 (1.2-18.8) months, respectively. Conclusion: A significant proportion of patients with mUC in Germany receive no systemic treatment.
What is this article about? This article reports the results from a study in Germany between 2015 and 2019 that investigated how advanced bladder cancer that has spread to other organs was treated and how long people lived after diagnosis. The study looked at systemic therapies, which means treatments that affect the entire body.What were the results? Only 40% of people diagnosed with advanced bladder cancer received systemic treatment within the first 12 months. Of those who did receive systemic treatment, the majority received combination therapy that included a chemotherapy drug containing platinum (64%). Systemic treatment was more likely to be given to people who were younger, less sick, male, or more recently diagnosed. After 12 months, 56% of treated people were still alive, compared with 26% of people without treatment. On average, people who received systemic treatment lived for about 14 months, while people without systemic treatment lived for only 3 to 4 months.What do the results of the study mean? Many people with advanced bladder cancer in Germany do not receive systemic treatment. People who receive treatment are likely to live longer than those who do not receive treatment.

INTRODUCTION: Hydrochlorothiazide (HCT) has been suggested to induce photosensitivity, thereby increasing the incidence of skin cancers. After a pharmacovigilance alert, HCT was frequently withdrawn or substituted by other diuretics. The aim of this study was to compare the association of exposure to HCT with cancer risk versus alternative diuretics. METHODS: A retrospective cohort study was conducted based on data from the AOK PLUS, a large German statutory health insurance fund. Patients with HCT treatment were propensity score matching to patients using non-HCT diuretics. Incidence of cancer of any kind and, specifically, skin cancer was assessed in both groups. Time-to-incident cancer diagnosis was evaluated and compared between the groups. RESULTS: A total of 199â708 patients were included in the final analysis ( n â=â76â855 in the HCT group; n â=â122â853 in the non-HCT-diuretics group). After propensity score matching, 122â554 patients remained in the sample ( n â=â61â277 for both groups, of which >96% had hypertension, mean age 73 years, 61% female). HCT treatment was associated with a lower incidence of cancer of any kind compared with non-HCT diuretics (incidence rate ratio per 100 patient years 0.84 95% confidence interval: 0.82-0.87). HCT treatment was associated with a small albeit significantly higher incidence rate ratio of skin cancer (1.15 95% confidence interval: 1.06-1.24) with significant variances over time. Although numerically higher, the difference accounts to only 0.05 more skin cancer diagnoses in 100 patient-years. CONCLUSION: HCT treatment compared with alternative diuretics was associated with a lower all-cancer risk and a numerically small increased skin cancer risk in a large German population. Risk-benefit evaluation should be executed in patients with increased skin cancer risk and treatment with HCT. Furthermore, advice for skin protection is warranted in all patients taking thiazide or thiazide-like diuretics.

BACKGROUND: Asthma causes various clinical symptoms, including unpredictable severe exacerbations, and even though most patients can achieve a reasonable disease control due to adequate treatment, some patients do not. This study seeks to describe healthcare resource utilization (HCRU) and treatment of asthma and severe asthma patients in Germany. METHOD: A retrospective claims data analysis has been conducted on adult asthma patients and a subset of patients with severe asthma, identified during July 2017 - June 2018. A proxy was used to identify severe asthma patients based on therapy options recommended within the German treatment guideline for treating these patients. These include (i) biologics, (ii) medium/high-dose inhaled corticosteroids (ICS) in conjunction with LABA/montelukast and antibiotics/oral corticosteroids (OCS), and (iii) long-term OCS therapy. HCRU and treatment of patients were observed during a 1-year follow-up period (July 2018 - June 2019). RESULTS: The study included 388 932 adult asthma patients (prevalence: 7.90%), with 2.51%-12.88% affected by severe asthma (depending on the definition). 22.60% of all asthma patients experienced hospitalizations (severe asthma: 36.11%). Furthermore, 13.59% received OCS (severe asthma: 39.91%), but only 0.18% (severe asthma: 1.25%) received biologics. Only 23.95% (severe asthma: 41.17%) visited a pulmonologist. CONCLUSIONS: A considerable proportion of severe asthma patients receive long-term OCS therapy. However, less than 50% have seen a pulmonologist who would typically seek a change in treatment to avoid the long-term consequences of OCS. To optimize the treatment of severe asthma in Germany, better referral of these patients to specialists is needed and considering potential treatment alternatives.

BACKGROUND: People with multiple sclerosis (pwMS) have a higher risk of serious infection (i.e., infection-related hospitalizations) than people without MS. Few studies have explored the risk of serious infections by MS phenotype in a real-world setting. This retrospective study compared the incidence of serious infections among people with relapse remitting MS (RRMS), primary progressive MS (PPMS), and secondary progressive MS (SPMS). METHODS: Adult pwMS were selected from a German claims database, based on one inpatient or two outpatient diagnoses of MS (ICD-10 G35) by a neurologist from 01/01/2016 to 12/31/2018. Three cohorts (RRMS, PPMS, SPMS) were identified based on codes for MS subtypes included in the German Modification of the ICD-10 system. A fourth cohort of unspecified MS patients combined those with conflicting MS subtype diagnoses and multiple unspecified codes for MS. Serious infections were defined as hospitalizations for which infections were selected as the primary inpatient diagnosis. Infections were identified from a basket of ICD-10 codes distributed across 11 main categories, according to possible pathogen (e.g., other bacterial diseases [A30-A49]) or anatomical location (e.g., urinary tract infection [N39.0]). Multiple infections were counted if an interval of at least 60 days was recorded between episodes. Serious infections were counted from index (i.e., first recorded MS code) until the end of the study period or death. Incidence rates (IRs) were reported per 100 patient years (PY). RESULTS: A total of 4,250 pwMS (RRMS: 2,307, PPMS: 282, SPMS: 558, unspecified MS: 1,135) were included; 32 patients progressed from RRMS to SPMS during the follow-up period. Mean (SD) age at baseline was 46.6 (13.6), 61.9 (12.4), and 62.5 (11.8) years in patients with RRMS, PPMS, and SPMS, respectively. Most pwMS were female (RRMS 74.8%, PPMS 62.1%, SPMS 67.4%). Progressive pwMS were more likely to have at least 1 comorbidity (PPMS 87.2%, SPMS 87.5%) compared to those with relapsing MS (61.9%). Most RRMS patients received disease-modifying therapy during follow-up (82.1%), while less than half of progressive MS patients did (PPMS 23.8%, SPMS 31.4%). Over a mean (SD) follow-up period of 3.5 (0.8) years, the IR of serious infections per 100 PY was higher in progressive MS cohorts (PPMS 13.5 [11.3-16.1], SPMS 13.6 [12.0-15.3]) than in the RRMS group (3.4 [3.0-3.7]). Yearly IRs remained stable over time in each cohort. Where anatomical location was specified, respiratory (2.0 per 100 PY) and genitourinary (1.9 per 100 PY) infections were most common. Across all subtypes, higher rates of serious infections were observed in men and older patients. CONCLUSION: Progressive MS, older age and male sex are associated with an increased risk of serious infections. Overall, respiratory and genitourinary infections were the most commonly reported serious infections.

Background: Asthma is one of the most common chronic diseases in Germany. While many patients achieve asthma control under standard therapies, some patients still experience exacerbations and persistent airway obstructions. Thus, further pharmacological treatment is needed, and biologics could fill this gap, as they have shown clinical benefit in patients with severe asthma. Therefore, this real-world study aimed to compare healthcare resource utilization (HCRU) and associated costs before and after biologic therapy initiation. Methods: A retrospective claims data analysis has been conducted on adult asthma patients who initiated a long-term biologic therapy between January 2015 and June 2018. Patients were therapy-naïve to biologics for at least 12 months. HCRU and cost incurred by patients during 12 months before and after therapy initiation were compared. Results: Overall, 571 asthma patients initiated a biologic therapy during the observational period (316 omalizumab, 232 mepolizumab, 16 benralizumab, and 7 reslizumab). Patients had a mean age of 54.86 (62.70% female), and the majority (93.70%) received at least one follow-up prescription of their index-biologic agent within one year. During baseline, patients received on average 2.75 OCS prescriptions compared to 2.17 during follow-up. Most patients received less or the same amount of OCS after therapy initiation. Moreover, hospitalizations and asthma-related sick leave days decreased significantly. The average total costs per patient were 6618.90 during baseline and 22,832.33 during follow-up. Biologics mainly drove the increase; however, hospitalization costs were reduced significantly (2443.37 vs 1941.93; p<0.001). Conclusion: Our study demonstrates an improved asthma control due to the initiation of a biologic therapy in terms of decreased hospitalization frequency, OCS consumption, and sick leave days. However, biologics are associated with high costs for healthcare providers during the first year after initiation. Therefore, short- and long-term clinical benefits and financial burden must be considered in the overall context of healthcare.
RÉSUMÉ
BACKGROUND/AIM: Rhabdomyolysis is associated with the release of myoglobin into the circulation, promoting acute kidney injury (AKI). In severe rhabdomyolysis, dialysis-dependent AKI doubles mortality. Standard blood purification techniques have limited efficacy in removing myoglobin. We describe high cut-off (HCO) renal replacement therapy (RRT) as a novel approach for extracorporeal elimination of myoglobin in rhabdomyolysis-associated AKI. METHODS: With an in vivo molecular cut-off at 45 kDa, HCO filters are effective in removing myoglobin (17.8 kDa). Clearances across standard and HCO filters using continuous or intermittent RRT are reviewed in a case series of 11 patients with severe rhabdomyolysis and dialysis-dependent AKI. RESULTS: Median myoglobin clearance across standard high-flux filters was 3.3 (interquartile range 2.3-3.9) ml/min for sustained low-efficiency daily dialysis (SLEDD) batch hemodialysis (HD) and 3.7 (2.9-6.7) ml/min for conventional HD. Respective clearances using HCO filters (membrane surface area: 1.1 m(2)) were 21.7 (20.3-26.1) ml/min (SLEDD) and 44.2 (41.3-47.0) ml/min (HD). Corrected for filter size, up to 20-fold higher clearances were obtained using HCO filters, resulting in profound and sustained reduction of plasma myoglobin concentration. CONCLUSIONS: As a novel approach, HCO RRT allows for rapid and effective removal of myoglobin from the circulation. In light of the pathogenic role in AKI, reducing exposure of the kidney to myoglobin may improve renal recovery and patient outcome. Our data pave the way for prospective trials, addressing this issue.
