Comparison of immunoglobulin levels in various forms of inflammatory bowel disease
| Ig levels | All patients (n = 324) | CD (n = 185) | UC or IC (n = 41) | Ileal pouch (n = 98) | P-value |
|---|---|---|---|---|---|
| IgG | 980.5 (747.3–1200.0) | 940.5 (697.0–1170.0) | 1060.0 (806.0–1230.0) | 1040.0 (819.5–1290.0) | 0.042 |
| IgG1 | 577.5 (457.3–760.3) | 556.0 (384.0–720.0) | 589.0 (467.0–864.0) | 634.0 (485.3–765.8) | 0.25 |
| IgA | 223.0 (142.0–312.5) | 211.5 (140.5–325.3) | 176.0 (119.5–252.5) | 229.5 (166.0–331.0) | 0.062 |
| IgM | 107.5 (64.5–164.8) | 99.5 (60.8–152.3) | 112.0 (71.0–182.5) | 115.0 (85.0–203.0) | 0.099 |
Ig levels were measured in mg/dL and described as medians and interquartile ranges.
CD = Crohn’s disease; IC = indeterminate colitis; UC = ulcerative colitis.
