In this article, the acid-base disturbances encountered in hematologic diseases are discussed. Occurrence of lactic acidosis (LA) without obvious clinical tissue hypoxia has been reported in patients with leukemia and lymphoma. Most of the patients with LA had liver involvement and clinical evidence of impaired hepatic function, suggesting that both increased production and decreased lactate metabolism are necessary for the development of LA in leukemia and lymphoma. Acute tumor lysis syndrome consists of hyperuricemia, hyperpotassemia, and hyperphosphatemia with hypocalcemia following neoplastic cell lysis, particularly in lymphoproliferative disorders. In patients with multiple myeloma (MM), proximal renal tubular acidosis (Fanconi syndrome) associated with Bence Jones proteinuria has been reported. In addition, MM is one of the first conditions recognized to be associated with lower anion gap.

Serum hyperviscosity syndrome was diagnosed in 2 cats with multiple myeloma. Clinical signs included pale mucous membranes, dehydration, retinal hemorrhages, dilated and tortuous retinal vessels, seizures, head-tilt, nystagmus, systolic murmur, and gallop rhythm. Laboratory abnormalities included hyperglobulinemia, azotemia, hyperphosphatemia, nonregenerative anemia, and thrombocytopenia. Both cats had IgG monoclonal gammopathy, Bence Jones proteinuria, increased numbers of bone marrow plasma cells, and high values for relative serum viscosity. Renal disease was suspected in both cats. Cardiac hypertrophy was documented in 1 cat and was suspected in the other cat. Chemotherapy, using melphalan, prednisone, and vincristine, caused short-term remission in both cats, and plasmapheresis was used to lower serum protein concentration in 1 cat. Serum hyperviscosity syndrome rarely develops in cats, but should be suspected when monoclonal gammopathy exists with signs of neurologic, cardiac, or retinal disease.

Many renal structural and functional abnormalities have been associated with sickle cell disease. The patients have an impaired urinary concentrating ability but an intact diluting capacity. There are defects in both urinary acidification and potassium excretion, although overt metabolic acidosis and hyperkalemia occur infrequently. Proximal tubular function is supranormal, as manifested by increased reabsorption of phosphate and increased secretion of creatinine. The former results in mild hyperphosphatemia, while the latter causes substantial overestimation of the glomerular filtration rate (GFR) by creatinine clearance. Both GFR and renal plasma flow are increased in young patients with sickle cell disease, but prostaglandin inhibitors decrease the GFR. The GFR progressively decreases with increasing age. Proteinuria, and even nephrotic syndrome, are relatively frequent; the most common renal lesion in children is focal glomerular sclerosis, which may be associated with progressive deterioration in renal function. Glomerular hyperfiltration has been implicated in the pathogenesis of the glomerular lesions, as well as in the development of renal failure. In patients with end-stage renal disease, both hemodialysis and kidney transplantation have been successful. Recurrent hematuria is a relatively common problem in patients with sickle cell disease. The bleeding usually remits spontaneously, but occasionally requires therapy with aminocaproic acid. Papillary necrosis may occur, and is thought to result from medullary ischemia.

Renal amyloidosis was diagnosed in 14 young Chinese Shar Pei dogs, all of which were related. Clinical signs were those of renal failure and included vomiting, anorexia, lethargy, polydipsia, polyuria, weight loss, and dehydration. Some dogs had a history of intermittent fever and joint swelling. Laboratory findings also were compatible with renal failure and included azotemia, hyperphosphatemia, low total CO2 content in serum, isosthenuria, proteinuria, and hypercholesterolemia. All dogs had medullary deposition of amyloid, and 9 of 14 (64%) had glomerular involvement. The remaining renal lesions were typical of end-stage renal disease. In some dogs, amyloid deposits were found in other tissues (eg, liver, spleen, stomach, small intestine, myocardium, lymph node, prostate gland, thyroid gland, and pancreas). Amyloid deposits were sensitive to potassium permanganate oxidation, suggesting the presence of amyloid protein AA.

The medical records of 59 dogs with renal amyloidosis were reviewed. Most dogs with amyloidosis were greater than 6 years old, and females were affected more often than males. Beagles, Collies, and Walker Hounds were at increased risk, whereas German Shepherd Dogs and mixed-breed dogs were at decreased risk. Common historical findings were anorexia, polyuria, polydipsia, lethargy, vomiting, and weight loss. Common laboratory findings were leukocytosis, lymphopenia, nonregenerative anemia, hypercholesterolemia, azotemia, hyperphosphatemia, metabolic acidosis, isosthenuria, cylindruria, and proteinuria. Proteinuria was moderate to severe in most dogs, as assessed by qualitative determination of urine protein concentration, urine protein/urine creatinine ratio, and 24-hour urine protein excretion. Conservative medical management was of little value, and survival ranged from 3 to 20 months in 12 dogs for which this information was available. Moderate to severe diffuse global glomerular amyloidosis was detected in all dogs. Medullary amyloid deposition was multifocal and less severe, but was evident in most dogs. Secondary tubulointerstitial and glomerular lesions were mild or absent in most dogs. Thromboembolism was identified in approximately 14% of affected dogs, underlying inflammatory disease in 37%, and neoplasia in 20%. Laboratory indicators of renal function correlated poorly with histologic lesions, with the exception of glomerular amyloid deposition and "chronic renal disease" index with endogenous creatinine clearance.

In a 10-year retrospective study, we evaluated the clinicopathologic features and renal immunofluorescence patterns of glomerulonephritis in 41 dogs. On the basis of results of histologic examinations, the dogs were segregated into 3 groups, including membranous (n = 12), mesangioproliferative (n = 15), or membranoproliferative glomerulonephritis (n = 14). No significant differences existed among groups in regard to age or duration of illness. Most dogs had been ill for one month or longer. The proportion of dogs with azotemia, anemia, and hyperphosphatemia were not different among the disease groups. Proportion of dogs with hypoalbuminemia and the severity of hypoalbuminemia were not different among groups. Highest urine protein losses and 24-hour urine protein/creatinine ratios developed in dogs with membranous glomerulonephritis. Although hypoalbuminemia and hypercholesterolemia were common (49%), the formation of edema or ascites was not (15%) and, therefore, few dogs had all of the classic features of the nephrotic syndrome. Few dogs suffered thromboembolic complications. Antinuclear antibody titers developed in 11 dogs, the highest titers developing in dogs with polyarthritis and systemic lupus erythematosis. Cellulose acetate electrophoresis detected alpha 2 and beta 1 globulin spikes in most dogs (87%). Results of renal immunofluorescence testing were positive in 36 dogs, using polyvalent antisera for immunoglobulins (Ig)G, IgA, IgM, and/or antisera for complement factor C3. When monovalent antisera for IgG, IgA, and IgM, and fibrinogen were used, immunofluorescence was not observed as often. The major fluorescent pattern was discrete multifocal segmental granular glomerular fluorescence, consistent with immune-complex deposition. Two dogs had linear glomerular staining patterns; however, antibodies directed against normal glomerular basement membrane were not found via elution studies. A high prevalence of glucocorticoid excess (treatment with glucocorticoids and spontaneous hyperadrenocorticism) (34%), chronic inflammatory skin disease (27%), neoplasia (17%), polyarthritis (12%), and systemic lupus erythematosis (7%) were observed as clinical problems concurrent with glomerulonephritis. In 5 dogs, treatment of glomerulonephritis with prednisolone (0.5 to 1.1 mg/kg) did not result in beneficial effects and in fact appeared to be detrimental, leading to azotemia and worsening proteinuria and physical condition in some of the dogs.(ABSTRACT TRUNCATED AT 400 WORDS)

Chronic renal failure was diagnosed in 6 young Standard Poodles from 2 related litters. Clinically, the disease was characterized by polydipsia, polyuria, anorexia, lethargy, vomiting, and bony deformities suggestive of fibrous osteodystrophy. Laboratory evaluation revealed azotemia and hypercholesterolemia in all 6 dogs and nonregenerative anemia in 3 dogs. Two dogs had hyperphosphatemia and another 2 were hypercalcemic. Isosthenuria and proteinuria were found in both dogs for which urinalyses were available. The kidneys were characterized pathologically by interstitial fibrosis, variable interstitial infiltrates of lymphocytes and plasma cells, tubular atrophy, tubular dilatation, tubular basement membrane mineralization, cystic glomerular atrophy, and immaturity of glomeruli, with inconspicuous capillary lumens.

Clinicopathologic findings were retrospectively evaluated in 26 cats and 24 dogs with ethylene glycol intoxication. Common clinical signs were ataxia, depression, vomiting, and hypothermia. Characteristic alterations in the hemogram and serum chemical profile included neutrophilia, lymphopenia, azotemia, hyperphosphatemia, hypocalcemia, hyperglycemia, and decreased whole blood bicarbonate. Common urinalysis findings included isosthenuria, proteinuria, glucosuria, hematuria, calcium oxalate and hippurate crystalluria, and the presence of renal epithelial cells, white blood cells, and granular and cellular casts in the urine sediment. The high death rate (78%) was attributed to delays in presentation, diagnosis, and therapy.

Renal amyloidosis was diagnosed in 8 related Abyssinian cats. The kidneys were characterized pathologically by medullary interstitial and glomerular amyloid deposition, interstitial fibrosis, and papillary necrosis. Amyloid deposits were birefringent under polarized light after Congo red staining, were thioflavine-T positive, and lost Congo red staining after permanganate oxidation. Four of the cats were evaluated clinically. Two of these cats were terminally uremic, with nonregenerative anemia, azotemia, hyperphosphatemia, metabolic acidosis, mild hyperglycemia, isosthenuria, proteinuria, cylindruria, and mild hematuria. The remaining 2 cats were only moderately azotemic. Three of the cats had severe gingivitis and all 4 cats had hyperproteinemia due to hyperglobulinemia.
