ABSTRACT
AIM: Hypoglycaemia in Type 1 diabetes is associated with mortality and morbidity, especially where awareness of hypoglycaemia is impaired. Clinical pathways for access to continuous glucose monitoring (CGM) and flash glucose monitoring technologies are unclear. We assessed the impact of CGM and flash glucose monitoring in a high-risk group of people with Type 1 diabetes. METHODS: A randomized, non-masked parallel group study was undertaken. Adults with Type 1 diabetes using a multiple-dose insulin-injection regimen with a Gold score of ≥ 4 or recent severe hypoglycaemia were recruited. Following 2 weeks of blinded CGM, they were randomly assigned to CGM (Dexcom G5) or flash glucose monitoring (Abbott Freestyle Libre) for 8 weeks. The primary outcome was the difference in time spent in hypoglycaemia (below 3.3 mmol/l) from baseline to endpoint with CGM versus flash glucose monitoring. RESULTS: Some 40 participants were randomized to CGM (n = 20) or flash glucose monitoring (n = 20). The participants (24 men, 16 women) had a median (IQR) age of 49.6 (37.5-63.5) years, duration of diabetes of 30.0 (21.0-36.5) years and HbA1c of 56 (48-63) mmol/mol [7.3 (6.5-7.8)%]. The baseline median percentage time < 3.3 mmol/l was 4.5% in the CGM group and 6.7% in the flash glucose monitoring. At the end-point the percentage time < 3.3 mmol/l was 2.4%, and 6.8% respectively (median between group difference -4.3%, P = 0.006). Time spent in hypoglycaemia at all thresholds, and hypoglycaemia fear, were different between groups, favouring CGM. CONCLUSION: CGM more effectively reduces time spent in hypoglycaemia in people with Type 1 diabetes and impaired awareness of hypoglycaemia compared with flash glucose monitoring.

INTRODUCTION: Extra-pulmonary complications of Burkholderia cepacia complex (Bcc) infection in patients with cystic fibrosis are unusual. To the best of the authors' knowledge no case of pyomyositis secondary to Bcc infection has been reported previously. CASE PRESENTATION: We report a case of pyomyositis of the forearm caused by Bcc infection in a patient with CF. We also briefly discuss the management of pyomyositis. CONCLUSION: Pyomyositis is a potential extra-pulmonary complication of Bcc infection in patients with CF. A high index of clinical suspicion is required to make a prompt diagnosis. Final diagnosis may need MRI. An early diagnosis, aggressive medical therapy, multidisciplinary care and timely surgical intervention are all essential for proper management of this condition.
