Drug Survival of Tumor Necrosis Factor-Alpha Inhibitors and Switched Subsequent Biologic Agents in Patients with Psoriasis: A Retrospective Study.

INTRODUCTION: This study aimed to retrospectively examine the drug survival of tumor necrosis factor (TNF)-alpha inhibitors and switched subsequent biologic agents after discontinuation of TNF inhibitors. METHODS: This real-world setting study was conducted at a single academic center. We included patients who were treated with adalimumab (n = 111), certolizumab pegol (n = 12), and infliximab (n = 74) at Jichi Medical University Hospital from 1 January 2010 to 31 July 2021. RESULTS: No significant differences were noted in drug survival between the three TNF inhibitors. The 10-year drug survival rate for adalimumab and infliximab was 14% and 18%, respectively. Of the patients who discontinued TNF inhibitors for any reason (n = 137), 105 chose biologics as their subsequent treatment. The subsequent biologics included 31 cases of TNF inhibitors (adalimumab in 20, certolizumab pegol in 1, and infliximab in 10), 19 of interleukin-12/23 inhibitor (ustekinumab), 42 of interleukin-17 inhibitors (secukinumab in 19, brodalumab in 9, and ixekizumab in 14) and 13 of interleukin-23 inhibitors (guselkumab in 11, risankizumab in 1, and tildrakizumab in 1). Cox proportional hazards analysis for the subsequent drugs in cases of discontinuation due to inadequate efficacy revealed that female sex was a predictor of drug discontinuation (hazard ratio 2.58, 95% confidence interval 1.17-5.70) and that taking interleukin-17 inhibitors rather than TNF inhibitors was a predictor of drug persistence (hazard ratio 0.37, 95% confidence interval 0.15-0.93). CONCLUSIONS: Interleukin-17 inhibitors may be a favorable option for patients who need to switch from TNF inhibitors due to inadequate efficacy. However, this study is limited by the small number of cases and its retrospective design.

With many biologic options available for the treatment of psoriasis, choosing the optimal drug can be challenging, especially when switching drugs. Tumor necrosis factor (TNF) inhibitors are the oldest category of biologics used for psoriasis, with adalimumab and infliximab being available since 2010 and certolizumab pegol since 2019 in Japan. In this study, we examined the drug survival of TNF inhibitors in patients treated with adalimumab (n = 111), certolizumab pegol (n = 12), and infliximab (n = 74) at Jichi Medical University Hospital from 1 January 2010 to 31 July 2021. No significant differences were noted in drug survival between the three TNF inhibitors, and the 10-year drug survival rate for adalimumab and infliximab was 14% and 18%, respectively. We examined the drug survival of subsequent biologics used by patients who discontinued TNF inhibitors for any reason (n = 137) and found that among patients who discontinued TNF inhibitors due to inadequate efficacy, female sex was a predictor of drug discontinuation and that taking interleukin-17 inhibitors rather than TNF inhibitors was a predictor of drug continuation. The study results suggest that interleukin-17 inhibitors is a favorable option for patients who discontinue TNF inhibitors due to inadequate efficacy and need to switch to other agents. However, this study has limitations, including the small number of cases and the single-center and retrospective study design.

Single-center survey of incidental imaging findings on computed tomography in patients with psoriasis on biologic therapy.

Psoriasis is an immune-mediated chronic inflammatory disease that predominantly affects the skin and joints. Systemic therapies are required for patients with moderate-to-severe psoriasis, and biologics can provide significant symptomatic improvement. Computed tomography (CT) analysis is recommended before and after biologic therapy to exclude the possibility of comorbid infections and malignancies; incidental findings are often detected in asymptomatic patients. In this study, we analyzed the common incidental findings on CT in 227 patients with psoriasis on biologic therapy and 219 living-kidney transplant donors at our hospital. Incidental findings on CT were observed in 176 (77.5%) patients with psoriasis. The most common were fatty liver (82 patients, 36.1%), urolithiasis (54 patients, 23.8%), pulmonary lesions (47 patients, 20.7%), gallstones or postoperative gallstones (38 patients, 16.7%), liver cysts (36 patients, 15.9%), renal cysts (33 patients, 14.5%), and colonic diverticulum (22 patients, 9.7%), which were observed in 38 (17.4%), eight (3.7%), 68 (31.1%), 12 (5.5%), 58 (26.5%), 88 (40.2%), and 10 (4.6%) donors, respectively. The prevalence of fatty liver, urolithiasis, gallstones, and postoperative gallstones was significantly higher in patients with psoriasis. Multivariate logistic regression showed that psoriasis was a risk factor for fatty liver disease, urolithiasis, and gallstones. Currently, incidental findings on CT in patients with psoriasis have not been well studied. The results of this survey will lead to increased awareness of the incidental findings on CT as a complication of psoriasis.

Four-year drug survival of apremilast in patients with psoriasis.

This real-world study at a single academic center retrospectively examined the drug survival of apremilast for patients with psoriasis. Retrospective information was extracted from the medical records of patients with psoriasis treated with apremilast at the Department of Dermatology, Jichi Medical University Hospital, between March 1, 2017, and June 31, 2021. In total, 281 patients were included in this study. Of these patients, 22% had psoriatic arthritis and 57% had a history of prior systemic treatment, including biologics, before the initiation of apremilast. The 1-, 2-, 3-, and 4-year drug survival rates were 54%, 41%, 32%, and 30%, respectively. Cox regression analysis revealed that sex, duration of plaque psoriasis (<10 years vs ≥10 years), presence of psoriatic arthritis, involvement of scalp lesions, involvement of palmoplantar lesion, involvement of nail lesions, having cardiometabolic comorbidities, and a history of prior systemic treatment did not have any significant impact on drug survival. The most common reason for apremilast discontinuation was inadequate efficacy (27%), followed by adverse events (12%). Approximately 49% of the patients experienced one or more adverse events. Diarrhea was the most common adverse event (24%), followed by nausea (19%) and headache (11%).

Histopathological Features of Cancer-Associated Venous Thromboembolism: Presence of Intrathrombus Cancer Cells and Prothrombotic Factors.

BACKGROUND: Cancer-associated venous thromboembolism (VTE) is a critical complication in patients with cancer. However, the pathological findings of VTE are limited. Here, we investigated the histopathological features of cancer-associated VTE in human autopsy cases. METHODS: We clinically examined the autopsy cases of VTE with (n=114) and without cancer (n=66) and immunohistochemically analyzed the expression of prothrombotic factors in intrathrombus cancer cells, the thrombus contents of erythrocytes, fibrin, platelets, citrullinated histone H3, and degree of organization. RESULTS: Vascular wall invasion or small cell clusters of cancer cells was observed in thrombi in 27.5% of deep vein thrombosis and 25.9% of pulmonary embolism cases. The majority of the cancer cells in deep vein thrombi appeared to be invading the vessel wall, whereas the majority of pulmonary thrombi had cancer cell clusters, consistent with embolization via blood flow. These cancer cells were immunohistochemically positive for TF (tissue factors) or podoplanin in up to 88% of VTE cases. The frequency of TF-positive monocyte/macrophages in thrombi was higher in cancer-associated VTE than that in VTE without cancer. Citrullinated histone H3 was predominantly observed in the early stages of organizing thrombi. There was no significant difference in thrombus components between VTE with cancer and without cancer groups. CONCLUSIONS: Vascular wall invasion or cancer cell clusters in thrombi might influence thrombogenesis of cancer-associated VTE. TF and podoplanin in cancer cells and in monocyte/macrophages may induce coagulation reactions and platelet aggregation. Neutrophil extracellular traps may play a role in the early stages of VTE, regardless of cancer status.

Single-center survey of biologic use for inflammatory skin diseases during the coronavirus disease 2019 pandemic.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The ongoing COVID-19 pandemic has affected both daily life and medical care; therefore, the aim of this study was to analyze the use of biologics for inflammatory skin diseases during the COVID-19 pandemic in our hospital. The observation period was between 1 January 2020 and 23 February 2021. In this study, we enrolled 227 patients with psoriasis, six patients with palmoplantar pustulosis (PPP), 69 patients with atopic dermatitis (AD), and five patients with hidradenitis suppurativa (HS). Bioswitch was performed in 25 patients with psoriasis (11.0%). Biologics were discontinued in 14 patients with psoriasis (6.2%), 10 patients with AD (14.5%), and four patients with HS (80.0%); they were not discontinued in patients with PPP. The introduction of biologics was observed in 27 patients with psoriasis (11.9%), four patients with PPP (66.7%), 33 patients with AD (47.8%), and two patients with HS (40.0%). The use of telephone consultations was observed in four patients with psoriasis and two patients with AD. One patient, who received adalimumab for the treatment of psoriatic arthritis, suffered from COVID-19 and recovered after a mild course. In conclusion, we report our experience regarding the use of biologic drugs for inflammatory skin diseases. The use of biologics seemed safe for use amidst COVID-19 infection during the observation period; however, further observation on a larger number of patients is required to confirm the risks and benefits of biologic use in the COVID-19 era.

Tissue factor expression and tumor-infiltrating T lymphocytes in ovarian carcinomas and their association with venous thromboembolism.

Ovarian cancer is a known risk factor of venous thromboembolism (VTE). Thrombogenic factor expression and lymphocytic infiltrate have been reported in endometriosis and ovarian cancers. We reviewed 30 cases of ovarian carcinomas (high grade serous carcinoma, 10; endometrioid carcinoma, 10; clear cell carcinoma (CCC), 10) and 16 endometriotic lesions. We immunohistochemically investigated the expressions of tissue factor (TF), podoplanin, P-selectin, and number of CD4 and CD8 positive lymphocytes in cancer tissue and endometriotic lesions, along with their relationship with VTE. The expression of TF was higher in CCC. The TF expression and the number of CD8 positive cells were higher in cancer tissues with VTE than in those without VTE. The podoplanin or P-selectin expression did not differ among histological types or between cases with and without VTE. Our results demonstrated a high TF expression and intraepithelial CD8 cells in CCC, which were associated with VTE. The results suggest that infiltrating lymphocytes may affect TF expression that, in turn, influences VTE.

Socioeconomic status and gastric cancer survival in Japan.

BACKGROUND: Few studies have investigated the association between socioeconomic status and the survival of cancer patients in Japan. METHODS: We examined whether occupation or educational level was associated with the survival of 725 gastric cancer patients who were diagnosed within an ongoing large population-based cohort study. RESULTS: After adjustment for age at diagnosis, and sex, we found that, compared with professionals or office workers, unemployed subjects (hazard ratio [HR], 2.23; 95% confidence interval [CI], 1.27-3.92) and manual laborers (HR, 1.68; 95% CI, 1.07-2.62) had an increased risk of gastric cancer death. After further adjustment for the clinical extent of disease, the increased risk disappeared. Educational level was not associated with the risk. CONCLUSIONS: These findings suggest that a disparity in survival by occupation exists among Japanese gastric cancer patients, largely due to a lower proportion of early disease among the unemployed and manual laborers.

Reliability and validity of the Multidimensional Health Locus of Control Scale in Japan: relationship with demographic factors and health-related behavior.

We assessed the reliability and validity of the Multidimensional Health Locus of Control Scale (MHLC scale) in a rural Japanese community. The study subjects were 2388 men and 2454 women aged 40-79 years, who completed a questionnaire regarding socio-demographics, health-related behavior, such as smoking and drinking, and the MHLC. The Cronbach alpha of the MHLC scale, which is an indicator of the internal consistency of the scale, was within the range 0.62-0.76. Elderly subjects, women, and subjects with fewer years of education showed more "external" belief, which is generally consistent with previous reports from overseas. Subjects with adverse health behavior, such as smoking and excess drinking, also had more "external" belief. These results indicate that the MHLC scale has sufficient reliability and validity among the Japanese population. Use of the MHLC scale should help to provide a better understanding of health belief among Japanese, and development of health education programs to prevent lifestyle-related disease.

Validation of walking questionnaire for population-based prospective studies in Japan: comparison with pedometer.

PURPOSE: To assess the reproducibility and validity of a single-item, self-administered questionnaire on walking used in two population-based prospective cohort studies in northern Japan, using pedometer counts as the reference standard. METHODS: Fifty-one men and 55 women participating in the main cohort studies (mean age: 61.7 years) responded to a question on the average duration of walking per day five times at 3-month intervals. The subjects also provided 3 consecutive days of pedometer counts four times along with the first four questionnaire surveys. RESULTS: For the first and the fifth questionnaires administered one year apart, 55% of the subjects chose concordant categories among three options (< or = 30 min/ between 30 and 60 min/> or = 60 min), and 13% chose the highest category in one questionnaire and the lowest in the other questionnaire. The sex- and age-adjusted mean daily numbers of walking steps counted by the pedometer were 5,857, 7,047, and 7,621 for the three categories of walking duration in the fifth questionnaire, and it showed significant linear associations with all of the five questionnaire measurements. CONCLUSION: The single-item questionnaire on walking is reasonably reproducible and valid, and useful in studying the health effects of walking among the Japanese population.
