Secondary amyloidosis was diagnosed in five Rhesus monkeys with chronic indwelling venous catheters. Diagnostic enzymology demonstrated normal serum alanine aminotransferase concentration and consistently elevated serum alkaline phosphatase. Serum protein electrophoresis on all five animals showed a typical pattern of decreased albumin and increased gamma globulin. Necropsy or biopsy specimens verified the presence of amyloid deposits in all animals. The diagnostic usefulness of clinical enzymology, serum protein electrophoresis and liver biopsy were demonstrated and the importance of considering amyloidosis as a differential diagnosis in monkeys with indwelling vascular catheters is emphasized.

Secondary amyloidosis is a progressive systemic disease for which there is no reliable diagnostic assay, preventive measure, or treatment. In an attempt to elucidate an antemortem diagnosis, 30 female pig-tailed macaques (Macaca nemestrina) at the Washington National Primate Research Center were surveyed for amyloidosis. Amyloid was demonstrated histologically in 47% (14 of 30) of the animals. The distribution and severity of amyloid deposition was variable. Affected animals had a mean age (+/-1 standard deviation) of 13.2 +/- 4.9 y, which was significantly greater than the mean age of unaffected animals (9.3 +/- 4.1) y. Twelve tests were evaluated for detection of amyloidosis; the diagnostic value of each was determined through comparison of histologically positive and histologically negative animals. Diagnostic tests evaluated were endoscopic examination and biopsy of the stomach and colon, abdominal ultrasonography, hepatic radiology, serum amyloid A (SAA), endothelin 1, alpha-fetal protein, aspartate aminotransferase (AST), alanine aminotransferase, gamma-glutamyltransferase (GGT), alkaline phosphatase, cholesterol, blood urea nitrogen, total bilirubin, C-reactive proteins, and erythrocyte sedimentation rate. Amyloidotic animals demonstrated a distinctive serologic profile: elevated SAA, GGT, and AST in combination with decreased total protein and albumin. Radiology demonstrated hepatomegaly in animals with hepatic amyloid deposition. In the absence of known infection or trauma, an amyloidotic serologic profile and radiologic hepatomegaly are consistent with systemic amyloidosis in M. nemestrina.

Amyloidosis is characterized by extracellular deposition of abnormal protein. There are six types: primary, secondary, hemodialysis-related, hereditary, senile, and localized. Primary (AL) amyloidosis is associated with monoclonal light chains in serum and/or urine with 15% of patients having multiple myeloma. Secondary (AA) amyloidosis is associated with inflammatory, infectious, and neoplastic diseases. The presentation is protean, including macroglossia, a dilated and atonic esophagus, gastric polyps or enlarged folds, and luminal narrowing or ulceration of the colon. Amyloid deposition in the gastrointestinal (GI) tract is greatest in the small intestine. The symptoms include diarrhea, steatorrhea, or constipation. Pseudo-obstruction carries a particularly grave prognosis, often not responding to pro-motility agents. Hepatic involvement is common, but the clinical manifestations are usually mild with hepatomegaly and an elevated alkaline phosphatase level. Biopsies to diagnose amyloidosis can be taken from the fat, kidney, intestine, or bone marrow. The safety of liver biopsies is controversial. With Congo Red stain, amyloid appears red in normal light and apple-green in polarized light. Treatment for AL amyloidosis is chemotherapy and stem cell transplantation; treatment for AA amyloidosis is control of the underlying disease. Amyloidosis should be considered in patients with proteinuria, cardiomyopathy, hepatomegaly (with mildly abnormal liver tests), peripheral and autonomic neuropathy, weight loss, and GI symptoms.

A 48-year-old lady presented with a parotid mass found to be secondary to recurrent sialadenitis. She was also found to have microcytic anemia, renal dysfunction, an elevated gamma gap, and an isolated alkaline phosphatase elevation. Later, she developed altered mental status and shock, and was found to have adrenal insufficiency, pulmonary hypertension, and pulmonary nodules. A liver biopsy was consistent with amyloid deposition. The constellation of findings was consistent with systemic amyloid A (AA) amyloidosis secondary to recurrent sialadenitis with hepatic, renal, pulmonary, and adrenal involvement. The patient later passed away due to acute hypoxic respiratory failure. This case demonstrates rare sequelae of systemic AA amyloidosis of pulmonary hypertension and adrenal insufficiency.
