Abstract
Psoriasis is an immune-mediated inflammatory skin disease, involving a complex interplay between genetic and environmental factors. Previous studies have demonstrated that genetic factors play a major role in the pathogenesis of psoriasis. However, non-genetic factors are also necessary to trigger the onset and recurrence of psoriasis in genetically predisposed individuals, which include infections, microbiota dysbiosis of the skin and gut, dysregulated lipid metabolism, dysregulated sex hormones, and mental illness. Psoriasis can also be induced by other environmental triggers, such as skin trauma, unhealthy lifestyles, and medications. Understanding how these triggers play a role in the onset and recurrence of psoriasis provides insights into psoriasis pathogenesis, as well as better clinical administration. In this review, we summarize the triggers for the onset and recurrence of psoriasis and update the current evidence on the underlying mechanism of how these factors elicit the disease.

Front Endocrinol (Lausanne) 2024; 15:1323994. [PMID: 38405150 PMCID: PMC10884096 DOI: 10.3389/fendo.2024.1323994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 01/23/2024] [Indexed: 02/27/2024] Open
Abstract
Background Thyroid autoimmunity is one of the most prevalent autoimmune diseases. However, its association with extra-thyroid diseases and mortality risk in the general population remains uncertain. Our study aims to evaluate the association of thyroid autoimmunity with extra-thyroid disease and the risk of mortality. Methods A prospective cohort study was conducted using data from the National Health and Nutrition Examination Survey (NHANES) with participants from 2007-2008, 2009-2010, and 2011-2012, tracking their mortality until 2019. Associations between thyroid autoimmunity, which was defined as having positive thyroid peroxidase antibody (TPOAb) and/or thyroglobulin antibody (TgAb), and extra-thyroid disease including diabetes, hypertension, cardiovascular disease, chronic lung disease, arthritis, cancer and chronic renal disease and the risk of mortality were investigated. Results A total of 7431 participants were included in this study. Positive The prevalence of positive TgAb was 7.54%, and positive TPOAb prevalence was 11.48%. TgAb was significantly associated with diabetes (Model 1: OR=1.64, 95% CI:1.08-2.50; Model 2: OR=1.93, 95% CI: 1.21-3.08) and hypertension (Model 1: OR=0.67, 95% CI: 0.49-0.91; Model 2: OR=0.62, 95% CI: 0.44-0.88). TPOAb was associated with a lower prevalence of chronic lung disease (model 1: OR=0.71, 95% CI: 0.54-0.95; model 2: OR=0.71, 95% CI: 0.53-0.95). No associations were observed between TgAb, TPOAb and other extra-thyroid diseases. Neither TgAb nor TPOAb were associated with all-cause mortality or heart disease mortality. Conclusion TgAb was linked to a higher prevalence of diabetes and a lower prevalence of hypertension, while TPOAb was associated with a decreased prevalence of chronic lung disease. However, neither TgAb nor TPOAb posed a risk for all-cause mortality or heart disease mortality.

Abstract
Introduction Guillain-Barré syndrome (GBS) is an autoimmune disorder targeting the peripheral nervous system. The neutrophil-to-lymphocyte ratio (NLR), a simple indicator of immune function, is potentially related to its incidence and severity; however, this should be confirmed. We aimed to evaluate the role of NLR in the diagnosis, severity, and prognosis of GBS. Methods Data of GBS patients and controls visiting our hospital from January 2010 to December 2020 were retrospectively analyzed (Clinical trial registration: ChiCTR2100053540). Risk factors were determined through logistic regression. Smoothing curves, receiver-operating characteristic curves, and forest plots were drawn. Results We included 136 GBS patients and 211 controls. NLR, as a continuous variable, was associated with GBS risk (OR, 2.32; 95% CI, 1.68-3.21; p < 0.001), severe functional disability (OR, 1.23; 95% CI, 1.06-1.43; p = 0.006), severe weakness (OR, 1.19; 95% CI, 1.06-1.35, p = 0.004), and short-term prognosis (OR, 1.21; 95% CI, 1.08-1.36; p = 0.001). NLR was more strongly associated with GBS risk in older (≥60 years) (OR, 7.17; 95% CI, 2.38-21.61) or male (OR, 2.88; 95% CI, 1.78-4.64) patients than in younger (<60 years) (OR, 1.88; 95% CI, 1.37-2.57) or female (OR, 1.85; 95% CI, 1.24-2.77) patients. NLR was significantly associated with severe functional disability in faster disease progression (OR, 1.53; 95% CI, 1.03-12.29) and male patients (OR, 1.41; 95% CI, 1.03-1.92) versus in slower disease progression (OR, 1.12; 95% CI, 0.77-1.64) and female patients (OR, 1.12; 95% CI, 0.77-1.64). Conclusions NLR may be an independent GBS risk factor and predictor of severe functional disability, severe weakness, and short-term prognosis.

Abstract
BACKGROUND Androgen deprivation therapy (ADT) is the major treatment for metastatic prostate cancer (PCa), but few studies have investigated the effects of ADT on thyroid diseases. METHODS This population-based, nationwide cohort study utilized the Taiwan National Health Insurance Research Database (NHIRD) with 17,192 PCa patients between 1997 and 2013. We used the Cox proportional hazards models and propensity score-matched analysis to analyze the association between ADT and the development of thyroid diseases. RESULTS A total of 17,192 newly diagnosed men with PCa were selected from the NHIRD. There were 6200 ADT users and 6200 non-ADT users after 1:1 propensity score matching. There was a significantly decreased risk of thyroid diseases among ADT users compared with non-ADT users (adjusted hazard ratio (aHR): 0.79, 95% confidence interval (CI): 0.65-0.95, p < 0.001). Further analysis showed a significantly decreased risk of thyroid diseases with increasing ADT duration (p < 0.001). CONCLUSIONS The result showed that ADT use in men with PCa was associated with a decreased risk of thyroid disease development.

Association between Androgen Deprivation Therapy and the Risk of Inflammatory Rheumatic Diseases in Men with Prostate Cancer: Nationwide Cohort Study in Lithuania. J Clin Med 2022; 11:jcm11072039. [PMID: 35407647 PMCID: PMC8999943 DOI: 10.3390/jcm11072039] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 03/24/2022] [Accepted: 04/01/2022] [Indexed: 11/16/2022] Open
Abstract
Background: The aim of this study was to assess the association between androgen deprivation therapy (ADT) and the risk of inflammatory rheumatic diseases in men with prostate cancer. Methods: Patients with prostate cancer between 2012 and 2016 were identified from the Lithuanian Cancer Registry and the National Health Insurance Fund database, on the basis of rheumatic diseases diagnoses and information on prescriptions for androgen deprivation therapy. Cox proportional hazard models were used to estimate hazard ratios (HR) to compare the risks of rheumatic diseases caused by androgen deprivation therapy exposure in groups of prostate cancer patients. Results: A total of 12,505 prostate cancer patients were included in this study, out of whom 3070 were ADT users and 9390 were ADT non-users. We observed a higher risk of rheumatic diseases in the cohort of prostate cancer patients treated with ADT compared with ADT non-users (HR 1.55, 95% confidence interval (CI) 1.01−2.28). Detailed risk by cumulative use of ADT was performed for rheumatoid arthritis, and a statistically significant higher risk was found in the group with longest cumulative ADT exposure (>105 weeks) (HR 3.18, 95% CI 1.39−7.29). Conclusions: Our study suggests that ADT usage could be associated with increased risk of rheumatoid arthritis, adding to the many known side effects of ADT.

Acta Pharm Sin B 2022; 12:692-707. [PMID: 35256940 PMCID: PMC8897216 DOI: 10.1016/j.apsb.2021.07.016] [Citation(s) in RCA: 37] [Impact Index Per Article: 18.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 06/20/2021] [Accepted: 07/09/2021] [Indexed: 01/18/2023] Open
Abstract
Owing to incurable castration-resistant prostate cancer (CRPC) ultimately developing after treating with androgen deprivation therapy (ADT), it is vital to devise new therapeutic strategies to treat CRPC. Treatments that target programmed cell death protein 1 (PD-1) and programmed death ligand-1 (PD-L1) have been approved for human cancers with clinical benefit. However, many patients, especially prostate cancer, fail to respond to anti-PD-1/PD-L1 treatment, so it is an urgent need to seek a support strategy for improving the traditional PD-1/PD-L1 targeting immunotherapy. In the present study, analyzing the data from our prostate cancer tissue microarray, we found that PD-L1 expression was positively correlated with the expression of heterogeneous nuclear ribonucleoprotein L (HnRNP L). Hence, we further investigated the potential role of HnRNP L on the PD-L1 expression, the sensitivity of cancer cells to T-cell killing and the synergistic effect with anti-PD-1 therapy in CRPC. Indeed, HnRNP L knockdown effectively decreased PD-L1 expression and recovered the sensitivity of cancer cells to T-cell killing in vitro and in vivo, on the contrary, HnRNP L overexpression led to the opposite effect in CRPC cells. In addition, consistent with the previous study, we revealed that ferroptosis played a critical role in T-cell-induced cancer cell death, and HnRNP L promoted the cancer immune escape partly through targeting YY1/PD-L1 axis and inhibiting ferroptosis in CRPC cells. Furthermore, HnRNP L knockdown enhanced antitumor immunity by recruiting infiltrating CD8+ T cells and synergized with anti-PD-1 therapy in CRPC tumors. This study provided biological evidence that HnRNP L knockdown might be a novel therapeutic agent in PD-L1/PD-1 blockade strategy that enhanced anti-tumor immune response in CRPC.

Abstract
(1) Background: In Taiwan, prostate cancer is a major malignancy with an increasing incidence among men. This study explores the medical utilization of emergency departments among patients with prostate cancer in Taiwan. (2) Methods: This nationwide, population-based study was conducted via a cross-sectional method based on the Registry for Catastrophic Illness Patient Database from Taiwan’s National Health Insurance Research Database. Patients with newly diagnosed prostate cancer between 1997 and 2013 were enrolled in the study and divided into four treatment-related groups. The rate of emergency department presentation, disease categorization of emergency department visits, emergency department-related medical expenditures, and temporal trends were investigated. (3) Results: A total of 18,728 patients with prostate cancer were identified between 1997 and 2013, for whom 13,098 emergency department visits were recorded. The number of emergency department visits increased during the study period. The incidence rate for the medical utilization of emergency department visits was 822 per 1000 people during the study period. The incidence rates for patients with prostate cancer in the radical prostatectomy, radiotherapy, androgen deprivation therapy, and chemotherapy groups were 549, 1611, 1101, and 372, respectively. The average medical expenditure per emergency department visit was TWD 3779.8 ± 5116.2, and the expenditure was recorded for the chemotherapy group at TWD 4690.8 ± 7043.3. The most common disease diagnoses among patients with prostate cancer who presented to the emergency department were injury/poisoning (16.79%), genitourinary disorders (10.66%), and digestive disorders (10.48%). (4) Conclusions: This nationwide population-based study examined the emergency department visits of patients with prostate cancer in Taiwan, providing useful information for improving the quality of medical care.

Abstract
Purpose Helicobacter pylori (H. pylori) is a major risk factor for gastric cancer and may affect androgen activity in men. The association between H. pylori and androgen deprivation therapy (ADT) in patients with prostate cancer (PCa) remains unclear. Methods This retrospective cohort study linked National Health Insurance (NHI) data to Taiwan Cancer Registry (TCR) and Taiwan Death Registry (TDR) between 1995 and 2016. PCa patients who received ADT were classified into H. pylori infection and non‐H. pylori infection groups. The outcomes were overall mortality, prostate cancer‐specific mortality, and castration‐resistant prostate cancer (CRPC). Propensity score matching was adopted for the primary analysis and inverse probability of treatment weighting (IPTW) was used for the sensitivity analysis. Results Of the 62,014 selected PCa patients, 23,701 received ADT, of whom 3516 had H. pylori infections and 20,185 did not. After matching, there were 3022 patients in the H. pylori infection group and 6044 patients in the non‐H. pylori infection group. The mean follow‐up period for the matched cohort was 4.8 years. Compared to the non‐H. pylori group, the H. pylori group was significantly associated with decreased risks of all‐cause mortality (hazard ratio [HR] 0.90; 95% confidence interval [CI] 0.84–0.96) and prostate cancer‐specific mortality (HR 0.88; 95% CI 0.81–0.95) in the matched analysis. Conclusions H. pylori infection was associated with a reduced risk of mortality in PCa patients receiving ADT.

Abstract
OBJECTIVES We aimed to investigate whether the risk of diabetes mellitus (DM) is heightened in patients with prostate cancer receiving injection therapy. METHODS Men diagnosed with prostate cancer between 2000 and 2012 were included in the case cohort, and men without prostate cancer were included as controls. Each patient with prostate cancer was matched with a control patient with the same index year, demographic variables and comorbidities, and comparisons were made using propensity score matching. The hazard ratio of DM was estimated using the Cox proportional hazards model. RESULTS This cohort study consisted of 1213 patients with prostate cancer and 1213 control patients. The risk of DM in patients with prostate cancer was 1.60 times (95% CI = 1.12, 2.27) that of patients without prostate cancer. Compared with the controls, the hazard ratios of DM for patients with prostate cancer not receiving oral hormone therapy, patients with prostate cancer receiving oral hormone therapy, and patients with prostate cancer not receiving injection hormone therapy were 1.65 (95% CI = 1.01, 2.70), 1.57 (95% CI = 1.07, 2.70), and 1.94 (95% CI = 1.34, 2.81), respectively. The risk of DM in patients who received injection hormone therapy was 0.45 times (95% CI = 0.25, 0.82) that of patients who did not receive injection hormone therapy. CONCLUSION Patients with prostate cancer had an increased risk of DM compared with patients without prostate cancer. Patients with prostate cancer who received injection therapy had a lower risk of DM compared with those who did not.

[PMID: 34359762 PMCID: PMC8345520 DOI: 10.3390/cancers13153861] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 07/26/2021] [Accepted: 07/27/2021] [Indexed: 11/16/2022] Open
Abstract
The risk of dementia after androgen deprivation therapy (ADT) in patients with advanced prostate cancer (PCa) remains controversial. This study aimed to evaluate the association between ADT and the incidence of dementia in patients with PCa. We identified patients newly diagnosed with PCa in the National Health Insurance Database of Taiwan from 1 January 2002 to 30 June 2016 and in The Health Improvement Network of the United Kingdom (UK) from 1 January 1998 to 31 March 2018. We classified patients with PCa into ADT and ADT-naïve groups. Propensity score (PS) methods were used to minimize the differences in characteristics between the groups. We performed a Cox proportional hazard model to obtain the adjusted hazard ratio (HR) to compare the incidence of dementia between the groups. Our ADT group comprised 8743 and 73,816 patients in Taiwan and the UK, respectively, which were matched 1:1 to ADT-naïve patients by PS. The incidence rates of dementia in the ADT group were 2.74 versus 3.03 per 1000 person-years in the ADT naïve groups in Taiwan, and 2.81 versus 2.79 per 1000 person-years in the UK. There was no statistical difference between ADT and ADT-naïve groups (adjusted HR: 1.12; 95% confidence interval (CI): 0.87-1.43 in Taiwan and adjusted HR: 1.02; 95% CI: 0.85-1.23 in the UK). We found no association between the incidence of dementia and ADT in patients with advanced PCa in either database. Further studies are warranted to evaluate other possible triggers of incident dementia in patients receiving ADT for advanced PCa.

Risk of major adverse cardiovascular events among second-line hormonal therapy for metastatic castration-resistant prostate cancer: A real-world evidence study. Prostate 2021; 81:194-201. [PMID: 33393676 DOI: 10.1002/pros.24096] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 12/11/2020] [Accepted: 12/14/2020] [Indexed: 11/12/2022]
Abstract
BACKGROUND To evaluate the possible major adverse cardiovascular events (MACE) associated with second-line hormonal therapy in patients with metastatic castration-resistant prostate cancer (mCRPC). METHODS We performed a population-based real-world cohort study of 4962 prostate cancer patients between 2014 and 2017 utilizing the Chang Gung Research Database of Taiwan. The second-line hormonal therapies included enzalutamide and abiraterone acetate. The outcomes of interest were MACE, including acute coronary syndrome (ACS), ischemic stroke (IS), and heart failure (HF) events that resulted in hospitalization. Cox proportional-hazards models with inverse probability of treatment weighting (IPTW) with propensity scores were used. RESULTS After IPTW, 288 patients were prescribed second-line hormonal therapy and 1575 received first-line androgen-deprivation therapy (ADT). Of all patients diagnosed with MACE, the event rates were 2.92% in the second-line hormonal group and 2.22% in the first-line ADT group. The mean follow-up period was 9.52 months for the second-line hormonal group. Patients who received second-line hormonal therapy exhibited a significantly increased risk for MACE (hazard ratio [HR]: 3.15; 95% confidence interval [CI]: 2.03-4.89), ACS (HR: 4.94; 95% CI: 2.36-10.33), and HF (HR: 2.83; 95% CI: 1.53-5.25), compared with the first-line ADT group, but a similar risk for IS was observed in both groups (HR: 1.70; 95% CI: 0.95-3.04). CONCLUSIONS The real-world evidence study revealed increased risks for MACE in mCRPC patients receiving second-line hormonal therapy.

Abstract
Objectives: The objective of the study was to determine the risk of subsequent keratitis in prostate cancer (PCa) patients treated with androgen deprivation therapy (ADT). Materials and Methods: Three thousand three hundred and nine patients with PCa were identified using data from Taiwan’s National Health Insurance Research Database for 2001 through 2013. Among those patients, 856 treated with ADT comprised the study group, while 856 non-ADT-treated patients matched with 1:1 propensity-score-matched analysis comprised the control group. The demographic characteristics and comorbidities of all the patients were analyzed, and Cox proportional hazards regression was utilized to determine the hazard ratios (HRs) for subsequent keratitis. Results: A total of 157 (9.2%) patients had newly diagnosed keratitis. Compared to the non-ADT-treated patients, the ADT-treated patients had a reduced risk of subsequent keratitis, with an adjusted HR of 0.38 (95% confidence interval: 0.27–0.55; P < 0.001). Conclusion: ADT treatment apparently decreased the risk of subsequent keratitis in the investigated PCa patients, but the clinical significance of this finding should be further assessed in additional studies.

ZRSR2 overexpression is a frequent and early event in castration-resistant prostate cancer development. Prostate Cancer Prostatic Dis 2021; 24:775-785.

Abstract
BACKGROUND Androgen deprivation therapy (ADT) remains the leading systemic therapy for locally advanced and metastatic prostate cancers (PCa). While a majority of PCa patients initially respond to ADT, the durability of response is variable and most patients will eventually develop incurable castration-resistant prostate cancer (CRPC). Our research objective is to identify potential early driver genes responsible for CRPC development. METHODS We have developed a unique panel of hormone-naïve PCa (HNPC) patient-derived xenograft (PDX) models at the Living Tumor Laboratory. The PDXs provide a unique platform for driver gene discovery as they allow for the analysis of differentially expressed genes via transcriptomic profiling at various time points after mouse host castration. In the present study, we focused on genes with expression changes shortly after castration but before CRPC has fully developed. These are likely to be potential early drivers of CRPC development. Such genes were further validated for their clinical relevance using data from PCa patient databases. ZRSR2 was identified as a top gene candidate and selected for further functional studies. RESULTS ZRSR2 is significantly upregulated in our PDX models during the early phases of CRPC development after mouse host castration and remains consistently high in fully developed CRPC PDX models. Moreover, high ZRSR2 expression is also observed in clinical CRPC samples. Importantly, elevated ZRSR2 in PCa samples is correlated with poor patient treatment outcomes. ZRSR2 knockdown reduced PCa cell proliferation and delayed cell cycle progression at least partially through inhibition of the Cyclin D1 (CCND1) pathway. CONCLUSION Using our unique HNPC PDX models that develop into CRPC after host castration, we identified ZRSR2 as a potential early driver of CRPC development.

Abstract
COVID-19 has a clear sex disparity in clinical outcome. Globally, infection rates between men and women are similar; however, men are more likely to have more severe disease and are more likely to die. The causes for this disparity are currently under investigation and are most likely multifactorial. Sex hormones play an important role in the immune response with estrogen seen as immune boosting and testosterone as immunosuppressing. Additionally, an important protease involved in viral entry, TMPRSS2, is regulated by androgens. Many observational and prospective studies are ongoing or initiating to further examine the role of sex hormones in SARS-CoV-2 infection and if modulation of them is a realistic treatment option.

Abstract
Androgen deprivation therapy (ADT) is a cornerstone of treatment for prostate cancer and, in recent years, androgen receptor (AR)-targeted therapies (abiraterone and enzalutamide) have both been used for the treatment of castration-resistant prostate cancer (CRPC). In our study, we sought to investigate the association between ADT and immune disorders, considering a potential role of androgens in the immune modulation. We retrospectively evaluated CRPC patients treated with abiraterone/enzalutamide between July 2011 and December 2018. We assessed the risk of developing immune alterations and their impact on outcome. We included 844 CRPC patients receiving AR-directed therapies, of whom 36 (4.3%) had autoimmune diseases and 47 (5.6%) second tumors as comorbidities. Median age was 70 years [interquartile range (IQR) = 63–75)]. We showed higher significant incidence of autoimmune diseases during their hormone sensitive status (p = 0.021) and the presence of autoimmune comorbidities before starting treatment with abiraterone/enzalutamide was significantly associated with worse overall survival (OS) (10.1 vs. 13.7 months, HR = 1.59, 95% CI 1.03–2.27, p = 0.038). In a multivariate analysis, the presence of autoimmune disorders was an independent predictor of OS (HR = 1.65, 95% CI 1.05–2.60, p = 0.031). In conclusion, CRPC patients with autoimmune alterations before starting AR-directed therapies may have worse prognosis. Further prospective studies are warranted to assess the role of immune modulation in the management of prostate cancer patients.

Abstract
Renal calculi are common, with male predilection and androgen exposure potentially increasing the risk of renal calculi. Systemic effects of androgen deprivation therapy (ADT) have been observed but the influence of ADT on renal calculi in prostate cancer (PCa) patients is not fully understood. We conducted this population-based study to evaluate the impact of ADT on the subsequent risk of renal calculi. We used the National Health Insurance Research Database of Taiwan to analyze the incidences of renal calculi in ADT patients and non-ADT patients from 2001 to 2013. In total, 3309 patients with PCa were selected. After matching with 1:1 propensity-score analysis, 758 ADT patients with 758 matched non-ADT controls were enrolled in the final analysis. Demographic characteristics were analyzed and Cox regression analysis for calculating the hazard ratios (HR) was performed for the subsequent risk of renal calculi. Finally, 186 (186/1516, 12.3%) patients with diagnosed renal calculi were detected. ADT patients had a lower risk of subsequent renal calculi with an adjusted HR of 0.38 (7% vs. 17.5%, 95% confidence interval (CI) 0.28-0.53; p < 0.001) in comparison with the non-ADT group. The Kaplan-Meier curve showed significant differences of cumulative incidences of renal calculi. In conclusion, ADT patients had approximately one-third lower risk of subsequent renal calculi. Further studies are warranted to evaluate the clinical significance.

Abstract
We evaluated the efficacy of second-line hormonal therapy for treatment of metastatic castration-resistant prostate cancer (mCRPC) in a real-world retrospective study. We conducted a population-based real-world cohort study of 258 mCRPC patients between 2014 and 2018 using the Chang Gung Research Database (CGRD) of Taiwan. The second-line hormonal therapy included abiraterone acetate and enzalutamide. The clinical efficacy outcomes were overall survival (OS) and prostate-specific antigen (PSA) doubling time. The median PSA level was also assessed. In total, 223 mCRPC patients who underwent second-line hormonal therapy met all of the inclusion and exclusion criteria for this study. Among them, 65 (29.1%) patients were in the PSA response group and 158 (70.9%) were in the non-response group. The median age was 72.9 years. The median OS was 12.3 months (range: 9.9–19.9 months) and 9.6 months (range: 5.3–15.9 months) in the response and non-response groups, respectively, and the respective PSA doubling times were 9.0 months (range: 4.4–11.6 months) and 3.9 months (range: 2.2–9.1 months), with a median follow-up period of 10.5 months. A significantly longer median OS was seen in the PSA response group. This real-world database study demonstrated that clinical outcomes of second-line hormonal therapy were better in patients with a PSA response. Further studies are warranted to achieve a better understanding of second-line hormonal therapy for mCRPC in Asian populations.

Abstract
Purpose This study aimed to investigate the association between androgen deprivation therapy (ADT) and the risk of subsequently developing hematologic disorders in patients with prostate cancer. Materials and methods This population-based nationwide cohort study utilized data from the Taiwan National Health Insurance Research Database between 1997 and 2013. The patients were divided into three groups—those who received ADT only (ADT-only group), those who had radiotherapy (RT) only (RT-only group), and those treated with radical prostatectomy (RP) only (RP-only group). The study outcome was newly diagnosed hematologic disorder, including anemia and hematologic malignancy. Propensity score-matched, Cox regression, and Kaplan–Meier curve analyses were performed to investigate the risk of subsequently developing hematologic disorders after ADT. Results Of the 17,168 patients with prostate cancer who were included in the study, 13,318 met the inclusion and exclusion criteria. After propensity score matching, 1,797, 1,797, and 1,797 patients treated with ADT only, RT only, and RP only, respectively, who had a median follow-up period of 4.32 years were included in the study cohort. Compared with the patients treated with RP only, those who received ADT and RT were significantly at increased risk of subsequently developing hematologic disorders (ADT: adjusted hazard ratio [aHR]: 1.60, 95% confidence interval [CI]: 1.29–1.97; RT: aHR, 1.98, 95% CI: 1.62–2.42) according to the Cox regression analysis. Based on the Kaplan–Meier curve analysis, patients with bone metastasis who received ADT only had the lowest cumulative probabilities of not developing hematologic disorders. Moreover, a significantly increased risk of hematologic disorders was observed with the increasing duration of ADT (P for trend < .001). Conclusions The use of ADT in patients with prostate cancer may increase the risk of subsequently developing hematologic disorders.

[PMID: 31520539 DOI: 10.1111/jcpt.13046] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 07/27/2019] [Accepted: 08/23/2019] [Indexed: 12/17/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVE Hashimoto's thyroiditis, also referred to as autoimmune thyroiditis, is characterized by sexual dimorphism, suggesting an important role of sex hormones in its development. No interventional study has investigated whether drugs exerting antiandrogen properties affect thyroid antibody titres and thyroid function tests in subjects with autoimmune thyroiditis. METHODS This study included 35 levothyroxine-naïve men with euthyroid Hashimoto's thyroiditis. At the physician's discretion, 18 men were then treated with spironolactone (50-200 mg daily), while the remaining patients (n = 17) received other diuretics. Serum levels of thyrotropin, free thyroid hormones, testosterone and 25-hydroxyvitamin D, as well as titres of thyroid peroxidase and thyroglobulin, were measured at the beginning of the study and 6 months later. Based on hormone levels, constant structure parameters of thyroid homeostasis were calculated. RESULTS AND DISCUSSION At baseline, there was no difference between the treatment arms in terms of thyroid antibody titres, hormone levels and the calculated parameters of thyroid homeostasis. Thirty-two patients completed the study. Spironolactone increased thyroid antibody titres, decreased testosterone and 25-hydroxyvitamin D levels and reduced SPINA-GT. The drug produced a neutral effect on serum levels of thyrotropin, free thyroid hormones, Jostel's thyrotropin index and SPINA-GD. The effect of spironolactone on antibody titres correlated with treatment-induced changes in SPINA-GT, testosterone and 25-hydroxyvitamin D. No significant changes in antibody titres, hormone levels and the calculated parameters of thyroid homeostasis were observed in spironolactone-naïve men. WHAT IS NEW AND CONCLUSION The obtained results indicate that spironolactone may exert an unfavourable effect on progression of autoimmune thyroiditis in men.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) is a major pulmonary disease. However, few studies have investigated the relationship between COPD and prostate cancer (PCa). This study aimed to investigate the association between COPD severity and PCa risk. Patients and methods We conducted a nationwide population-based cohort study utilizing data from 2001 to 2013 from the National Health Insurance Research Database of Taiwan. Cox proportional hazards models with 1:1 propensity score-matched analysis were used to investigate the association between COPD and PCa risk. We further divided the COPD group according to severe complications (including acute respiratory failure, cardiopulmonary arrest, pneumonia, and acute exacerbation) to test for the relationship between COPD severity and PCa risk. Results This study included 47,634 patients (23,817 COPD patients and 23,817 matched non-COPD controls). Among them, 756 (1.59%) were diagnosed with PCa during a mean follow-up period of 7.05±4.13 years; 387 (1.62%) were from the COPD group and 369 (1.55%) were from the control group. Compared with the patients without COPD, the adjusted hazard ratio (HR) for PCa in the COPD patients was 1.10 (95% confidence interval [CI] 0.95–1.27), while that in the COPD patients with complications was 2.46 (95% CI 1.96–3.61). Conclusions An increased risk for PCa was found among the COPD patients with complications. COPD complications included acute respiratory failure, cardiopulmonary arrest, pneumonia, and acute exacerbation. These findings may help physicians in treating COPD with complications and in remaining alert to the potential development of PCa.

Abstract
INTRODUCTION Two recent observational studies have investigated the association between androgen deprivation therapy (ADT) and rheumatoid arthritis (RA), but generated discrepant findings and had important methodological limitations. Thus, the objective of this study was to determine whether the use of ADT is associated with an increased risk of RA in men with prostate cancer. PATIENTS AND METHODS We conducted a population-based cohort study using the United Kingdom Clinical Practice Research Datalink. The cohort included all men, at least 40 years of age, newly diagnosed with prostate cancer between 1 January 1988 and 31 March 2014, with follow-up until 30 September 2014. Exposure to ADT was treated as a time-varying variable and lagged by 1 year to account for diagnostic delays and latency. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of RA, comparing use of ADT with non-use. Secondary analyses were conducted to assess whether the association varied according to ADT type and cumulative duration of use. Finally, we conducted several sensitivity analyses to assess the robustness of our findings. RESULTS The cohort included 32,302 men followed for a median of 3.3 years. During follow-up, 63 patients were newly diagnosed with RA, generating an incidence rate of 46.5/100,000 person-years. Compared with non-use, the use of ADT was not associated with an increased risk of RA (HR 0.84, 95% CI 0.49-1.45). In secondary analyses, the association did not vary according to ADT type or with cumulative duration of use (p trend = 0.53). The results remained consistent in sensitivity analyses. CONCLUSION In this population-based study, the use of ADT was not associated with an increased risk of RA in men with prostate cancer.

Abstract
Membranous nephropathy is a cause of the nephrotic syndrome in adults; it can be a primary or secondary process. Secondary causes include solid organ and lymphoid malignancies. Prostate cancer has been reported as the second most common causative malignancy. Remission of membranous nephropathy following treatment of metastatic prostate cancer is well established. In this case, we describe a patient with localised prostate cancer who developed severe nephrotic syndrome (urine protein creatinine ratio 1,616 mg/mmol and serum albumin 17 g/L) secondary to membranous nephropathy. The prostate cancer was deemed of low risk and so was being managed with active surveillance rather than medical treatment. Given the severity of the nephrotic syndrome a trial of androgen deprivation therapy with bicalutamide was agreed between the nephrology and urology teams. Full remission of the nephrotic syndrome was observed within 6 months of commencement of treatment (normalisation of serum albumin, non-nephrotic range urine protein creatinine ratio and resolution of oedema). The bicalutamide has been continued indefinitely.

Abstract
OBJECTIVES Androgen deprivation therapy (ADT) use in prostate cancer (PCa) patients has been reported to have an association with rheumatoid arthritis. We aimed to assess the impact of ADT on the subsequent risk of tenosynovitis. METHODS Using data from the National Health Insurance Research Database of Taiwan between 2001 and 2013, 3309 patients with PCa were identified. Among them, 729 ADT patients comprised the study group with 729 matched non-ADT controls. We used a 1:1 propensity score matched analysis. The demographic characteristics and comorbidities of the patients were analyzed; Cox proportional hazards regression was used to calculate the hazard ratios (HR) for the risk of tenosynovitis. RESULTS There were 224 (15.3%) patients with newly diagnosed tenosynovitis. Compared with non-ADT patients, ADT patients had a lower risk of subsequent tenosynovitis with an adjusted HR of 0.38 [95% confidence interval (CI) 0.28-0.51; P < 0.001]. CONCLUSIONS ADT use apparently did not increase the risk of tenosynovitis in patients with PCa. Further studies are warranted to assess the clinical significance.

Abstract
Depression is associated with higher mortality in prostate cancer. However, whether traditional Chinese medicine (TCM) for depression improves outcomes in patients with prostate cancer is unclear. This retrospective cohort study evaluated the association between TCM for depression and mortality in patients with prostate cancer. During the period 1998⁻2012, a total of 248 prostate cancer patients in Taiwan with depression were enrolled and divided into three groups: TCM for depression (n = 81, 32.7%), TCM for other purposes (n = 53, 21.3%), and no TCM (n = 114, 46.0%). During a median follow-up of 6.2 years, 12 (14.8%), 13 (24.5%), and 36 (31.6%) deaths occurred in the TCM for depression, TCM for other purposes, and no TCM groups, respectively. After adjusting age at diagnosis, urbanization, insured amount, comorbidity disease, and prostate cancer type, TCM for depression was associated with a significantly lower risk of overall mortality based on a multivariate-adjusted Cox proportional-hazards model (hazard ratio 0.42, 95% confidence interval: 0.21⁻0.85, p = 0.02) and Kaplan⁻Meier survival curve (log-rank test, p = 0.0055) compared to no TCM. In conclusion, TCM for depression may have a positive association with the survival of prostate cancer patients with depression.
