Role of Clinical Features, Pathogenic and Etiological Characteristics of Community-acquired Pneumonia with Type 2 Diabetes Mellitus in Early Diagnosis.

OBJECTIVE

To study the etiological characteristics of community-acquired pneumonia (CAP) combined with type 2 diabetes (T2D), providing a reference for early clinical diagnosis and treatment of the disease.

METHODS

We selected a total of 93 patients with CAP and analyzed their metagenomics nextgeneration sequencing (mNGS) data. The case group comprised 46 patients with combined CAP/T2D, and the control group comprised 47 patients without diabetes. We analyzed the pathogenic findings of the two groups.

RESULTS

There were statistically significant differences in age between the two groups (P = 0.001). Leukocytes (P = 0.012), blood platelets (P = 0.034), fibrinogen (P = 0.037), D-dimer (P = 0.000), calcitonin ogen (P = 0.015), ultrasensitive C-reactive protein or C-reactive protein (CRP) (P = 0.000), serum amyloid A (P = 0.000), and erythrocyte sedimentation rate (P = 0.003) were higher in the case group than in the control group. Albumin was lower in the case group than in the control group. All differences were statistically significant. The infection rates of (P = 0.030), (P = 0.043), and (P = 0.032) were significantly different between the two groups.

CONCLUSION

Compared with those without diabetes, the infection rates of were higher in patients with combined CAP/T2D.
