Abstract
INTRODUCTION: Anemia of chronic inflammation is associated with many inflammatory diseases. Little is known about anemia in hidradenitis suppurativa (HS). This study aimed to review the levels of hemoglobin (Hb) and investigate its relationship with serum C-reactive protein (CRP) and disease severity in HS patients. METHODS: This was a retrospective chart review of all HS patients from 2015 to 2017 with Hb and CRP blood work. Patient demographics, disease severity, and laboratory results were extracted. Data were analyzed descriptively. A linear regression model was used for the association between Hb and CRP. Two-tailed t-tests and one-way ANOVA were used to compare differences between sexes and disease severities. RESULTS: Of the 25 patients included, 14 (56%) were female. The median age and disease duration of all patients were 41 years (range, 19-56 years) and 10 years (range, 1-40 years), respectively. The overall median CRP level was 11.5 mg/dL (range, 1-86.7 mg/dL). The median Hb levels for women and men were and 123.5 g/L (range, 90-142 g/L) and 152.0 g/L (range, 109-166 g/L), respectively. Anemia was found in 42.9% (6/14) of women and 27.3% (3/11) of men. There was an inverse relationship between Hb and CRP levels in both sexes (men: r = ‒0.88; P = .0006; women r = ‒0.65; P = .012). CONCLUSIONS: Anemia was prevalent in the HS population, and Hb levels inversely correlated with CRP. Physicians should be aware that anemia is common in inflammatory states, and that CRP could be a biomarker in patients with HS.
