AbstractIntroduction Patients with Multiple Myeloma (MM) often have a significant delay between onset of symptoms and diagnosis of disease. As a result, a significant number of patients present via emergency routes with severe co-morbidities which affect survival rates. Timely diagnosis relies on the early recognition of symptoms and blood test results which may indicate disease. Methods We examined the medical records of 142 newly diagnosed MM patients (121 intact immunoglobulin and 21 light chains) across 2 UK Hospitals. Patients included had not previously been diagnosed with a plasma cell dyscrasia, including Monoclonal Gammopathy of Undetermined Significance (MGUS). Clinical symptoms and blood test results were examined from the time of initial presentation to the healthcare system with symptoms indicative of MM, to the point of diagnosis in order to highlight patterns of symptoms and blood tests results which may give an early indication of disease. Blood tests results recorded included globulin, calcium, creatinine, erythroid sedimentation rate and haemoglobin. Time to diagnosis from presentation with symptoms indicative of MM was also measured as well as the patient pathway from the point of presentation to the point of diagnosis. Results The median time to diagnosis from initial presentation was 77 days (range 0 - 12,986). Initial presentation was most commonly via primary care (58.1%). Urgent secondary care presentation was documented in 28.5% which included acute medical unit (15.6%), the emergency department (7.1%), and other secondary care specialities (5.7%) respectively. Multiple GP visits were common prior to haematology referral with a median of 3 visits (range 1 - 40). Initial presenting symptoms varied, but of those with data recorded (n=107) back/bone pain was the most common (58.2%) followed by anaemia (18.7%), fracture (7.5%), recurrent infection (7.5%) and renal impairment (3.7%) respectively. Interestingly, analysis of evaluable blood test results revealed a raised globulin was most often evident prior to diagnosis with 58% of patients recording an abnormal globulin a median of 140 days (range 3 - 4297) prior to diagnosis of disease. Conclusions Multiple GP visits prior to establishing a diagnosis of myeloma is very common. Inclusion of abnormal globulin to reflex electrophoresis request and serum free light chain assay may serve as a useful trigger for investigation when interpreted alongside presenting symptoms and other blood test results. Increased awareness of myeloma warning signs in primary care may reduce diagnostic delay and avoid presentation with severe co-morbidities in emergency settings.

AbstractBackground: The association of dialysis fistulas and heart failure is believed to be due to high cardiac output. N-terminal pro-B-Type Natriuretic Peptide (pro-BNP) which is secreted by the cardiac ventricles in response to excessive stretching of the myocytes has been used as a marker of heart failure with 90% sensitivity. We report our early experience using pro-BNP levels to test the efficacy of the novel 'secondary extension technique' (SET) in improving myocardial function by reducing fistula flow. Method(s): Eleven patients with high fistula flows (>3000 mL/m, all brachio-cephalic) and raised pro-BNP underwent SET between 2011 and 2015. SET involves extending the anastomosis from brachial to either proximal radial or ulnar arteries. We measured pro-BNP levels, fistula flow and clinical improvements both pre and post operatively. Result(s): SET resulted in a median (IQR) flow rate decrease of 57.9 (11.9)% which correlated with a fall in pro-BNP of 69.6 (39)%. Seven of the 11 patients in the series pro-BNP level returned to a normal value at average follow-up of 3 months post SET. All patients had HOF-related symptom resolution post-procedure and remained asymptomatic at last follow-up Conclusion(s): Our pilot data suggests that SET is an effective way of reducing fistula flow. It also shows that BNP may be a reliable biomarker in assessing the impact of the technique on cardiac function. These results warrant further investigation in the form of a definitive, multicenter study.Copyright © 2021
