Background: Glycated hemoglobin A1c (HbA1c) among diabetic hemodialysis patients continues to be the standard of care, although its limitations are well recognized. This study evaluated glycated albumin (GA) and glycated serum protein (GSP) as alternatives to HbA1c in detecting glycemic control among diabetic hemodialysis patients using continuous-glucose-monitoring (CGM)-derived glucose as reference standard.Methods: A CGM system (iPRO) was applied for 7 days in 37 diabetic hemodialysis patients to determine glycemic control. The accuracy of GA and GSP versus HbA1c in detecting a 7-day average glucose ≥184 mg/dL was evaluated via receiver-operating-characteristic (ROC) analysis.Results: CGM-derived glucose exhibited strong correlation (r = 0.970, p < 0.001) and acceptable agreement with corresponding capillary glucose measurements obtained by the patients themselves in 1,169 time-points over the 7-day-long CGM. The area under ROC curve (AUC) for GA, GSP, and HbA1c to detect poor glycemic control was 0.976 (0.862-1.000), 0.682 (0.502-0.862), and 0.776 (0.629-0.923) respectively. GA levels >20.3% had 90.9% sensitivity and 96.1% specificity in detecting a 7-day average glucose ≥184 mg/dL. The AUC for GA was significantly higher than the AUC for GSP (difference between areas: 0.294, p < 0.001) and the AUC for HbA1c (difference between areas: 0.199, p < 0.01).Conclusion: Among diabetic hemodialysis patients, GA is a stronger indicator of poor glycemic control assessed with 7-day-long CGM when compared to GSP and HbA1c.

Background: Sweet's syndrome (SS) is an acute febrile neutrophilic dermatosis. It can occur as an idiopathic, drug-induced or malignancy-associated entity. SS is also seen in patients with myelodysplastic syndrome (MDS) where it may present atypically, both clinically and histologically. In a few rare cases of MDS, lymphocytic infiltrates are the presenting feature of SS. Methods: MEDLINE and Scopus were the data sources for our review. Results: A clinicopathological subset emerged of 12 male SS patients with MDS and a mean age of 67.3 years in which the initial SS lesions were lymphocytic infiltrates. However, from 0.5 to 8 years later, sequential biopsies revealed neutrophilic dermal infiltration typical of SS. Conclusion: Initially lymphocytic infiltrates in this subset could be attributed either to an early timing of the biopsy concerning the age of the lesion or to the dysgranulopoiesis syndrome. A possible relationship between the dysfunction of the receptor of the granulocyte-macrophage colony stimulating factor, the gene of which is located on the pseudoautosomal X-Y region, may exist in MDS patients with initially lymphocytic SS. This could explain the male gender of this subset and might establish initially lymphocytic SS as a distinguished clinicopathological entity for predicting the occurrence and even the prognosis of MDS. © 2014 S.
