The amylase/creatinine clearance ratio (Cam/Ccr ratio) was determined in 239 subjects. In 87 hospitalised patients without pancreatic disease (controls) the Cam/Ccr ratio was 3.02 +/- 0.69 (mean +/- ISD). The ratio was above the normal range in all patients with acute pancreatitis but was normal in those with chronic pancreatitis and carcinoma of the pancreas. In 18 patients with choledocholithiasis a raised ratio distinguished those with pancreatitis as assessed independently by the surgeon at laparotomy from those with a macroscopically normal pancreas. Raised Cam/Ccr ratios were also found in diabetics with ketoacidosis and in three patients with fulminant alcoholic liver disease. Though a positive correlation was found between the Cam/Ccr ratio and serum creatinine concentration, abnormally high ratios did not occur in 30 patients with chronic renal failure. A significant increase in Cam/Ccr ratios was produced in six healthy volunteers by intravenous injection of glucagon. However, it is unlikely that hyperglucagonaemia alone accounts for the increased Cam/Ccr ratio seen in acute pancreatitis, as no correlation was found between the clearance ratio and the plasma glucagon concentration in a series of patients. In two other patients in whom excess circulating pancreatic polypeptide was detected the Cam/Ccr ratio was normal. It is concluded that, in view of the sensitivity and relative specificity of finding an increased Cam/Ccr ratio in acute pancreatitis, its determination should be valuable clinically, especially in those cases of hyperamylasaemia where the cause is in doubt. The mechanism whereby the ratio is increased is unknown, and it is unlikely that either glucagon or pancreatic polypeptide is a major factor in its production.

Immunoglobulin (Ig)G4-related sclerosing disease (ISD) (also called IgG4-related systemic disease, IgG4-related disease or hyper-IgG4 disease) is a recently described systemic fibroinflammatory disease associated with elevated circulating levels of IgG4. Although initial descriptions of this disorder focused on its pancreatic presentation (autoimmune pancreatitis), it has become apparent that ISD is a systemic disease with many facets. The lesion of ISD is characterised by lymphoplasmacytic inflammation, fibrosis, phlebitis and increased numbers of IgG4-positive plasma cells. The disease can either be localised to one or two organs, or be present with diffuse multi-organ disease. Furthermore, lesions in different organs can present simultaneously or metachronously. In the thorax, lesions associated with ISD have been described in the lung parenchyma, airways and pleura, as well as the mediastinum. Data published to date suggest that ISD may account for a portion of various fibroinflammatory conditions of unknown cause encountered in the chest, including inflammatory pseudotumours, idiopathic interstitial pneumonias, fibrosing mediastinitis, inflammatory pleural lesions and, occasionally, airway disease. Some aspects of pulmonary manifestations attributed to ISD remain controversial and additional studies are needed to clarify the relationship along with the increasing relevance of this disorder to pulmonary medicine.
