Association between antibodies to carbonic anhydrase II (CA-II Ab), IgG4, clinical, morphological, and biochemical parameters in patients with idiopathic chronic pancreatitis
| Increased CA-II Ab% (n = 15) | Increased IgG4% (n = 8) | |
|---|---|---|
| Results are expressed as percentage of cases with increased CA-II Ab or IgG4 levels. | ||
