Acute phase ketosis-prone atypical diabetes is associated with a pro-inflammatory profile: a case-control study in a sub-Saharan African population

It is unknown whether inflammation plays a role in metabolic dysfunction on ketosis-prone diabetes (KPD). We aimed to assess the inflammatory profile in sub-Saharan African patients with KPD during the acute ketotic phase as well as during non-ketotic hyperglycemic crises. We studied 72 patients with non-autoimmune diabetes: 23 with type 2 diabetes mellitus (T2D), and 49 with KPD, all admitted in hyperglycemic crisis (plasma glucose ≥250 mg/dl). The T2D and KPD groups were matched by sex, age, and Body Mass Index. KPD was sub-classified into new-onset ketotic phase (n = 34) or non-ketotic phase (n = 15). We measured TNF-α, MCP-1, MIP1-α, IL-8, MIP1-β, and VEGF in the serum of all participants. TNF-α and IL-8 were higher in participants with KPD compared to those with T2D (p = 0.02 TNF-α; p = 0.03 IL-8). TNF-α and IL-8 were also higher in the ketotic phase KPD group compared to the T2D group (p = 0.03 TNF-α; p
