ABSTRACT
AIMS: Diabetic ketoacidosis (DKA) is an emergency with high morbidity and mortality. This study examined patient factors associated with hospitalization for recurrent DKA. METHODS: Characteristics of 265 subjects admitted for DKA at Hennepin County Medical Center between January 2017 and January 2019 were retrospectively analyzed. Differences between subjects with a single admission versus multiple were reviewed. RESULTS: Forty-eight out of 265 patients had recurrent DKA. Risk factors included African American race (adjusted odds ratio (aOR) versus white non-Hispanic = 4.6, 95% CI 1.8-13, p = 0.001) or other race/ethnicity (aOR = 8.6, 2.9-28, p < 0.0001), younger age (aOR 37-52y versus 18-36y = 0.48, 0.19-1.16, p = 0.10; aOR 53-99y versus 18-36y = 0.37, 0.12-0.99, p = 0.05), type 1 diabetes mellitus (aOR = 2.4, 1.1-5.5, p = 0.04), ever homeless (aOR = 2.5, 1.1-5.4, p = 0.03), and drug abuse (aOR = 3.2, 1.3-7.8, p = 0.009). DKA cost a median of $29,981 per admission. CONCLUSIONS: Recurrent DKA is costly, and social determinants are strong predictors of recurrence. This study highlights the need for targeted preventative care programs.
ABSTRACT
Pituitary collision tumors are sporadically reported and rare. We present a case of pituitary collision tumors with nonfunctioning pituitary adenoma (NFPA) and craniopharyngioma. In order to look for any common activated pathway, we examined WNT/ß-CATENIN signaling activation, known to be involved in tumorigenesis in both craniopharyngioma and NFPA. We found nuclear accumulation of ß-CATENIN protein and expression of LEF1 protein, markers of active ß-CATENIN signaling in the craniopharyngioma but not in the pituitary adenomas. In our case, the NFPA is invasive macroadenoma, which is a frequently identified type of pituitary adenoma in collision tumor cases. Recurrence of this tumor was first observed after 8 years of follow-up. Based on this case, we suggest that pituitary collision tumors require long-term follow-up.
