BertoliAbstractFew case series of pagophagia and iron deficiency include men. We performed a retrospective study of non-Hispanic white men with iron-deficiency anemia whose anemia and pagophagia, thrombocytosis, and thrombocytopenia (if present) resolved after iron replacement. Iron-deficiency anemia was defined as transferrin saturation (TS) <15%, serum ferritin (SF) <30 μg/L, and hemoglobin (Hb) <13.0 g/dL. We excluded men with: anemia, thrombocytosis, or thrombocytopenia due to non-iron-deficiency causes; malignancy; chronic inflammatory conditions; hemochromatosis; or creatinine>1.1 mg/dL. We computed univariate and multivariable pagophagia associations with: age; gastrointestinal bleeding; TS; SF; Hb; red blood cell (RBC) count; mean corpuscular volume (MCV); RBC distribution width (RDW); and platelet count. Median age of 41 men was 54 y (range 18–81). Fourteen men (34.1%) had pagophagia. Thirty-six men (87.8%) had gastrointestinal bleeding. Mean Hb was 9.4 ± 2.2 g/dL. Six men (14.6%) had thrombocytosis; two (4.9%) had thrombocytopenia. Logistic regression on pagophagia revealed: age (p = 0.0158; odds ratio 0.92 [95% confidence interval: 0.85, 0.99]) and platelet count (p = 0.0187; 0.98 [0.97, 1.00]) (41.4% of pagophagia occurrence; ANOVA p = 0.0053). We conclude that pagophagia occurre...
