Is there a role for Natural Desiccated Thyroid in the treatment of levothyroxine unresponsive hypothyroidism? Results from a Consecutive Case Series

Introduction Some levothyroxine unresponsive individuals with hypothyroidism are prescribed a Natural Desiccated Thyroid (NDT) preparation such as Armour Thyroid® or ERFA Thyroid®. These contain a mixture of levothyroxine and liothyronine in a fixed ratio. We evaluated the response to NDT in individuals at a single endocrine centre in terms of how the change from levothyroxine to NDT impacted on their lives in relation to quality of life (QOL) and thyroid symptoms. Methods The ThyPRO39 (thyroid symptomatology) and EQ-5D-5L-related QoL)/EQ5D5L (generic QOL) questionnaires were administered to 31 consecutive patients who had been initiated on NDT, before initiating treatment/6 months later. Results There were 28women/3men. The dose range of NDT was 60mg-180mg daily. Age range was 26-77 years with length of time since diagnosis with hypothyroidism ranging from 2-40 years. One person discontinued the NDT because of lack of response; 2 because of cardiac symptoms. EQ-5D-5L utility increased from a mean (SD) of 0.214 (0.338) at baseline, to 0.606 (0.248) after 6 months; corresponding to a difference of 0.392 (95% CI 0.241-0.542), t=6.82, p<0.001. EQ-VAS scores increased from 33.4 (17.2) to 71.1 (17.5), a difference of 37.7 (95%CI 25.2-50.2), t=-4.9, p<0.001. ThyPRO scores showed consistent fall across all domains with the composite QoL-impact Score improving from 68.3 (95%CI 60.9-75.7) to 25.2 (95%CI 18.7-31.7), a difference of 43.1 (95%CI 33. -53.2) (t=5.6, p<0.001). Conclusion Significant symptomatic benefit and improvement in QOL was experienced by people with a history of levothyroxine unresponsive hypothyroidism, suggesting the need for further evaluation of NDT in this context.

Benefits of blood transfusions in palliative care patients with advanced cancer.

e24090 Background: Anemia is highly prevalent in patients with advanced cancer and adversely affects quality of life. There is limited data on the frequency, clinical utility and effectiveness of red blood cell transfusions (RBC), and no randomized controlled trials or clinical practice guidelines on this subject are available. The aim of this study was to evaluate clinician practices on RBC transfusion in an oncologic palliative care unit (PCU), its impact on patients’ symptoms, overall survival and to identify predictive factors for survival. Methods: Retrospective cohort study of all advanced cancer patients who had received RBC transfusions over a 3-year period, after admission to the PCU for symptomatic control, as inpatients or outpatients. All had histologically confirmed malignant tumors and were not under anti-cancer treatments. Patients’demographics, clinical and laboratory features, symptoms and mortality were reviewed. Survival analysis was estimated using the Kaplan-Meier method and Cox's regression was used for multivariate analysis. Results: We identified 179 patients with a median age of 68 years [30-93], 60% were male, with a mean Charlson comorbidity index of 8.9 (SD ±2.3). The majority had gastrointestinal (42%) and genitourinary (35%) malignancies. A total of 435 RBC units, during 301 transfusion episodes were recorded. The majority (58%) were performed as inpatients. A combination of symptoms with low haemoglobin (Hb) levels was the main reason for transfusion (80%). Asthenia/fatigue was the most frequent symptom (68%). Prior to transfusion, the majority (73%) had an ECOG-performance status (ECOG-PS) greater than 2. The mean pretransfusion Hb was 6.9 g/dL and 48% patients had an Hb above 7 g/dL. Symptomatic benefit post-transfusion was achieved in 36% of patients. A statistically significant association between ECOG-PS and symptomatic benefit was found (p = 0.005). Median overall survival post-transfusion was 41 days (IC95% 30.6-51.4). On multivariate analysis, Hb level pre-transfusion, ECOG-PS and symptomatic benefit with transfusions were significantly associated with survival. Conclusions: Transfusion practices are more liberal in palliative care, increasing iatrogenic risk, while consuming a valuable and limited resource. However, transfusion does provide symptom relief, and should be offered to advanced cancer patients with a higher level of functioning. Post-transfusion symptomatic benefit, and pre-transfusion ECOG-PS and hemoglobin levels seem to be independent predictors of survival. Further high-quality trials are needed to develop validated measures of objective functional changes to evaluate the clinical impact of transfusions and to identify patients most likely to be positively impacted by transfusion.

Predicting benefit of radium 223 based on biochemical response and site of metastasis: A real life multicenter UK study.

e17034 Background: Studies have shown an improvement in overall survival (OS) and symptom control in metastatic castration-resistant prostate cancer (mCRPC) with Radium-223 treatment. However, there is little information about predicting outcomes using either PSA or Alkaline Phosphatase (ALP) response or comparing bone only disease to bone and lymph node (LN) involvement. Methods: 335 patients receiving Radium 223 at 6 UK centres between March 2014 and June 2020 were included. The primary endpoint was overall survival, secondary endpoints were toxicity, symptomatic benefit and skeletal-related events(SRE) Results: The median age was 75, with 71% having bone only metastases and 29% also having lymph node involvement. Those with PSA response (30%) had a statistically significant improvement in OS, compared to non-responders (18.2 vs 13.8 months, p = 0.026). They also showed highest rate of imaging response/stable disease (54% vs 34%). ALP response was seen in 82%. This did not translate to significantly improved OS, but did correlate with better symptomatic benefit (40% vs 29%). Those with bone only disease showed a survival benefit compared to those with LN involvement (19.4 vs 11.4 months, p = 0.046). Other than anaemia (23.5%), Grade 2 or above toxicities were uncommon including thrombocytopenia and neutropenia(5.5 and 6.2% respectively ) . 14% patients required at-least one blood transfusion. SRE were seen in 24% overall, but lower of in PSA responders(18%). Conclusions: Real life multicentre data suggests that PSA response and bone only disease could be predictors for better survival following Radium-223, whereas ALP response correlates better with symptomatic benefit.

Transfusion Practices In Advanced Cancer Patients

Purpose: Anemia is highly prevalent in patients with advanced cancer and adversely affects quality of life. There is limited data on the frequency, clinical utility and effectiveness of red blood cell transfusions (RBC), and no randomized controlled trials or clinical practice guidelines are available. The aim of this study was to evaluate clinician practices on RBC transfusion in an oncologic palliative care service (PCS) and its impact in patients’ symptoms, adverse events and overall survival.Methods: Retrospective analyses of all advanced cancer patients who received RBC transfusions admitted, during a 3-year period. Pre-blood counts, reason for transfusion, subjective benefit and objective outcomes were listed.Results: We identified 179 patients with a mean age of 67 years. A total of 435 RBC units, during 301 transfusion episodes were recorded. Asthenia/fatigue was the most frequent symptom (68%). The mean pretransfusion hemoglobin (Hb) was 6.85 g/dL and 48% patients had an Hb above 7 g/dL. Symptomatic benefit was achieved in 36% of patients. Adverse events were reported in 4%, with a 30-day survival rate of 57%. A statistically significant association between ECOG performance status (ECOG-PS) and symptomatic benefit was found (p=0.005). Hemoglobin level pre-transfusion, ECOG-PS and symptomatic benefit with transfusions were significantly associated with survival.Conclusion: This study suggests that advanced cancer patients with a higher level of functioning may have a bigger benefit from RBC transfusion. Post-transfusion symptomatic benefit, and pre-transfusion ECOG-PS and hemoglobin levels seem to be independent predictors of survival. Further studies are needed to develop validated measures of objective functional changes to evaluate the clinical impact of transfusions and to identify patients most likely to benefit from it.

Concomitant tricuspid regurgitation severity and its secondary reduction determine long-term prognosis after transcatheter mitral valve edge-to-edge repair

Background Concomitant tricuspid regurgitation (TR) is a common finding in mitral regurgitation (MR). Transcatheter repair (TMVR) is a favorable treatment option in patients at elevated surgical risk. To date, evidence on long-term prognosis and the prognostic impact of TR after TMVR is limited. Methods Long-term survival data of patients undergoing isolated edge-to-edge repair from June 2010 to March 2018 (combinations with other forms of TMVR or tricuspid valve therapy excluded) were analyzed in a retrospective monocentric study. TR severity was categorized and the impact of TR on survival was analysed. Results Overall, 606 patients [46.5% female, 56.4% functional MR (FMR)] were enrolled in this study. TR at baseline was categorized severe/medium/mild/no or trace in 23.2/34.3/36.3/6.3% of the cases. At 30-day follow-up, improvement of at least one TR-grade was documented in 34.9%. Severe TR at baseline was identified as predictor of 1-year survival [65.2% vs. 77.0%, p = 0.030; HR for death 1.68 (95% CI 1.12–2.54), p = 0.013] and in FMR-patients also regarding long-term prognosis [adjusted HR for long-term mortality 1.57 (95% CI 1.00–2.45), p = 0.049]. Missing post-interventional reduction of TR severity was predictive for poor prognosis, especially in the FMR-subgroup [1-year survival: 92.9% vs. 78.3%, p = 0.025; HR for death at 1-year follow-up 3.31 (95% CI 1.15–9.58), p = 0.027]. While BNP levels decreased in both subgroups, TR reduction was associated with improved symptomatic benefit (NYHA-class-reduction 78.6 vs. 65.9%, p = 0.021). Conclusion In this large study, both, severe TR at baseline as well as missing secondary reduction were predictive for impaired long-term prognosis, especially in patients with FMR etiology. TR reduction was associated with increased symptomatic benefit. Graphic abstract

Systematic Review of Thumb Carpometacarpal Joint Hemiresection Interposition Arthroplasty Materials

Background Osteoarthritis of the first carpometacarpal joint is a common condition. Various management options and surgical procedures have been described to treat symptomatic cases. Many systematic reviews examine aspects of thumb carpometacarpal joint osteoarthritis treatment, although none solely examines the outcomes of trapezial partial resection and interposition arthroplasty in stage II to III patients in detail, yet this technique is of growing interest as surgeons seek more nuanced, tailored approaches for osteoarthritis of the first carpometacarpal joint. Methods A systematic review of the thumb carpometacarpal joint hemiresection and interposition arthroplasty was performed with pain assessment as a primary outcome measure and patient-reported outcome measures (PROMs) and reoperation rate as secondary outcome measures. A search was performed between 2004 and 2019 using MEDLINE, Embase, and PubMed. Preferred Reporting Items and Systematic Reviews and Meta-Analyses guidelines were used. Results Twenty-nine articles met the inclusion criteria and were included in the final review. Pain relief and improved PROMs were described in all the articles using this technique with all the interposition materials. Materials such as polyurethane urea matrix and poly-l/d-lactide scaffold had higher complication rates. Revision rates varied and were highest with the polyurethane urea matrix. Conclusions This review shows that hemiresection interposition arthroplasty is a useful technique and provides symptomatic benefit in patients with Eaton-Littler stage II and III osteoarthritis. Revision surgery rates due to persistent pain and instability were higher with the use of implants. Larger and long-term studies of this technique using autologous or more bioinert materials and implants are required to assess duration of symptomatic benefit.
