What This Means
This research investigated whether three blood-based scoring systems — the HALP score (combining hemoglobin, albumin, lymphocyte, and platelet levels), the modified systemic immune-inflammatory index (mSII), and the modified systemic inflammatory response index (mSIRI) — could help identify how severe a patient's diabetic foot condition is. The study looked back at records from 367 patients with diabetic foot, dividing them into mild (lower Wagner grades) and severe (higher Wagner grades) groups. All three scores showed raw differences between mild and severe patients, but only the HALP score remained a significant predictor of severity after accounting for other factors like age, smoking history, and other health conditions.
Specifically, patients with a HALP score of 16.8 or below were more than twice as likely to have severe diabetic foot compared to those with higher scores. The mSII and mSIRI, despite showing differences between groups in initial comparisons, lost their predictive value when other health factors were taken into account. This suggests that the HALP score, which reflects both nutritional status and immune function, captures something uniquely relevant to diabetic foot severity that inflammation-only markers do not.
This research suggests that the HALP score could be a useful, relatively simple tool for clinicians to help gauge how serious a patient's diabetic foot condition is, potentially guiding earlier or more aggressive treatment decisions. Since diabetic foot complications can lead to amputation or life-threatening infections, having reliable markers of severity is clinically important. However, as this was a retrospective study, further prospective research would be needed to confirm these findings and establish clinical utility.
