Real-world evidence of sorafenib for the treatment of hepatocellular carcinoma: A single-center study.

Context: Hepatocellular carcinoma is the third leading cause of cancer death. Currently, sorafenib is the treatment of choice in advanced hepatocarcinoma. Aims: Assessing the effectiveness and toxicity of sorafenib in real-word clinical practice in patients with hepatocarcinoma. Settings and Design: Single-centered observational retrospective study. Methods and Material: We included patients with hepatocarcinoma who began treatment with sorafenib between 2008 and 2018. We evaluated overall survival, time to progression, and response using RECIST (Response Evaluation Criteria in Solid Tumors) criteria. Toxicity was assessed according to the Common Terminology Criteria for Adverse Events version 5. 2020. Statistical Analysis Used: Kaplan-Meier curves and the log-rank test were used to determine the survival time and estimate factors associated with these events. Data were analyzed with SPSS 19.0 software. Results: We included 36 patients (88.9% male) with an average age of 64 ± 3.4 years. The tumor stage was advanced (C) in 21 patients (61.8%). We obtained a median overall survival of 8.5 months (IQR 3.14-18.9) and a time to progression of 4.5 months (IQR 2.4-8.8). The main degree of response was progression in 19 patients (36.1%), followed by stable disease in 13 (52.8%). The most commonly reported adverse reactions were: constitutional (83.3%), gastrointestinal (55%) and dermatological symptoms (50.0%). The development of grades 3 or 4 toxicity was not associated with increased overall survival (P = 0.719). Conclusions: The findings of the survival analysis obtained in real practice are similar to those obtained in pivotal clinical trials. Adverse reactions were different from those expected.

Direct costs in patients with chronic inflammatory arthropathies on biological therapy: a real-world data study.

OBJECTIVES: The aim of the study was to assess the direct costs for the Spanish Health System of patients with chronic inflammatory arthropathies treated with biological therapies in daily clinical practice and to establish possible factors associated with lower costs. METHODS: A descriptive, observational and retrospective study was conducted. Patients with rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis who started a biological therapy between 1 January 2009 and 31 December 2016 were included. Variables related to socioeconomic status, disease and biological therapy were included. The annual cost of biological treatment and other direct medical costs were calculated for each disease. The analysis of costs was based on the National Health Service perspective. The time horizon comprised the 8-year long study period. RESULTS: A total of 422 biological therapy lines were analysed. The annual biological therapy cost per patient was €12,494±3,865 for rheumatoid arthritis, €11,248±2,763 for ankylosing spondylitis and €12,263±35,155 for psoriatic arthritis (p=0.008). The cost of biological therapies entailed about 80% of the total cost of these diseases. Hospital admission was a factor which contributed to an increasing cost in all these conditions. A longer duration of the biological therapy was associated with lower cost in all the diseases. CONCLUSIONS: The cost of ankylosing spondylitis is lower than that of rheumatoid arthritis and psoriatic arthritis. The biological therapy is the factor with the highest impact on the overall cost of these diseases. Preventing hospital admissions and a higher persistence to the biological therapy can contribute to lower costs for the system.

Medication persistence on biological therapies prescribed for the treatment of chronic inflammatory arthropathies: a real-world data study.

OBJECTIVES: Medication persistence, defined as the duration of time from its initiation to its discontinuation, is a surrogate for treatment effectiveness. The aim of the study was to evaluate persistence and causes of biological therapy (BT) suspension in patients with chronic inflammatory arthropathies: rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis. METHODS: Single institution, descriptive, retrospective cohort study. Adult patients with chronic inflammatory arthropathies on BT between January 2009 and December 2016 were included. Persistence to BT was compared considering the type of pathology and treatment. The Kaplan-Meier test was used to analyse medication persistanence and factors associated with it. An analysis of reasons for therapy discontinuation was performed. RESULTS: Three hundred and sixty-two patients were included in the study, which comprised 478 BT lines. For all patients, the 12-month persistence rate was 71.3% (341 out of 478). At the end of the study, 45.2% of the patients continued on their initial BT. Median treatment persistence was 1489 days (CI 95% 1195 to 1783). Longer BT persistence was associated with naïve BT patients: 1945 days (95% CI 1523 to 2367; P<0.001) and ankylosing spondylitis diagnosis: 2402 days (95% CI 1604 to 3200; P=0.014). The most frequent causes of treatment discontinuation were therapeutic failure (47.6%) and adverse drug events (28.2%). CONCLUSIONS: We found good long-term persistence in patients with chronic inflammatory arthropathies treated with BT. Patients with rheumatoid arthritis had significantly shorter persistence compared with those with ankylosing spondylitis and psoriatic arthritis. Naïve BT was associated with longer persistence. Therapeutic failure was the main cause of BT withdrawal.

Accuracy of transcutaneous bilirubin on covered skin in preterm and term newborns receiving phototherapy using a JM-105 bilirubinometer.

OBJECTIVE: Determine the suitability of transcutaneous bilirubin (TCB) as a tool to assess the effectiveness of phototherapy on patched skin. STUDY DESIGN: A prospective observational study was conducted. We covered a fragment of skin (sternum) with a photo-opaque patch. Several simultaneous TCB and TSB measurements were performed with the JM-105 bilirubinometer. Bland and Altman test evaluated the agreement between bilirubin levels. RESULT: A total of 217 patients were studied, 48.8% were preterm. The mean difference between TSB and TCB before the start of treatment was 1.07 mg/dL. During phototherapy, differences on covered skin were 0.52, 0.27, and 0.39 mg/dL at 24, 48, and 72 h of therapy respectively. The best correlation was observed at 48 h in preterm infants. CONCLUSION: The measurement of TCB on patched skin (PTCB) is useful for monitoring the response to phototherapy in term and preterm infants. We use a patch with a removable flap that eases successive measures without disturbing the patients.
