Sequential Impact of Diabetes Mellitus on Deep Neck Infections: Comparison of the Clinical Characteristics of Patients with and without Diabetes Mellitus.

BACKGROUND

Deep neck infections (DNIs) can compromise the airway and are associated with high morbidity and mortality rates. Diabetes mellitus (DM) is a metabolic disorder characterized by chronic hyperglycemia that is associated with several comorbidities. We compared the clinical characteristics of DNI patients with and without DM.

METHODS

This study recorded the relevant clinical variables of 383 patients with DNIs between November 2016 and September 2022; of those patients, 147 (38.38%) had DM. The clinical factors between DNI patients with and without DM were assessed.

RESULTS

Patients with DM were older ( < 0.001), had higher white blood cell counts ( = 0.029) and C-reactive protein levels (CRP, < 0.001), had a greater number of deep neck spaces ( = 0.002) compared to patients without DM, and had longer hospital stays ( < 0.001). was cultured more frequently from patients with DM than those without DM ( = 0.002). A higher CRP level (OR = 1.0094, 95% CI: 1.0047-1.0142, < 0.001) was a significant independent risk factor for DM patients with prolonged hospitalization. The lengths of hospital stays in patients with poorly controlled DM were longer than those with well-controlled DM ( = 0.027).

CONCLUSIONS

DNI disease severity and outcomes were worse in patients with DM than those without DM. Antibiotics effective against should be used for DNI patients with DM. DNI patients with DM and high CRP levels had more prolonged hospitalizations. Appropriate blood glucose control is essential for DNI patients with DM.
