Primary disorders of water balance (central diabetes insipidus, congenital nephrogenic diabetes insipidus, and psychogenic polydipsia) should always be considered in the differential diagnosis of polyuria and polydipsia. In general, animals with these disorders have only one laboratory abnormality, a low urine specific gravity. The more common causes of polyuria and polydipsia (eg, hypercalcemia, chronic renal insufficiency, pyelonephritis, hyperadrenocorticism), in most instances, have specific and obvious abnormalities associated with the complete blood count (CBC), serum chemistry profile, and urinalysis. However, in some cases, a low urine specific gravity may initially be the only abnormality in these more common ruleouts. The workup for polyuria and polydipsia, especially in those cases with normal or near normal blood work, can be tedious, time consuming, confusing, and not without significant patient morbidity. This chapter will focus on the problems associated with diagnostic testing used to evaluate animals with disorders of water balance.

Experimental pyelonephritis was induced by intravenous inoculation of Staphylococcus aureus in homozygous Brattleboro diabetes insipidus (Hom Brattleboro DI), heterozygous Brattleboro (Het Brattleboro) and Wistar rats. One group of rats from each strain was implanted with morphine-containing pellet three days before inoculation. Another series of groups received D-aspartic acid (D-ASP) intraperitoneally, starting three days before inoculation throughout the experiments. Owing to the inhibition by morphine or D-ASP of food intake, another control group from each strain was subjected to food restriction. Pyelonephritis development on the tenth day of inoculation was evaluated by the determination of viable bacteria in urine and total kidney tissue, and pathomorphological lesions in kidney. Hom Brattleboro DI rats appeared more resistant. Morphine or D-ASP significantly increased the findings in three strains of rat.

A comparative study was performed on haematogenous experimental pyelonephritis by injecting a Staphylococcus aureus suspension i.v. to homozygous and heterozygous Brattleboro and Wistar rats. The numbers of viable bacteria in blood, urine and kidney homogenates and the pathomorphological scores determined on the tenth day of infection were significantly lower in Brattleboro diabetes insipidus rats than in heterozygous Brattleboro and normal Wistar rats. The results suggest that homozygous Brattleboro rats are much more resistant to experimental pyelonephritis.

The etiology of persistent hypokalemia and renal potassium loss was investigated in three children. Each had normal blood pressure but low plasma aldosterone values in relation to elevated plasma renin activity. None had a history of licorice abuse, laxative or diuretic use, persistent vomiting or diarrhea, pyelonephritis, or diabetes insipidus. Additional studies in one patient showed low prostaglandin E excretion and a normal platelet aggregation response to epinephrine and ADP. Although certain aspects of this condition resemble Bartter syndrome, the low concentrations of aldosterone and the absence of evidence for mineralocorticoid excess suggest a previously undescribed syndrome.

Primary disorders of water balance (central diabetes insipidus [DI], nephrogenic DI, and psychogenic polydipsia) should always be considered in the differential diagnosis of polyuria and polydipsia. In general, animals with these disorders have only one laboratory abnormality: a low urine specific gravity. In most instances, the more common causes of polyuria and polydipsia (e.g., hyperadrenocorticism, chronic renal failure, pyelonephritis, pyometra) have specific and obvious abnormalities associated with the complete blood cell count, the serum chemistry profile, and urinalysis. In some cases, however, a low urine specific gravity may be the only abnormality associated with these more common findings. The workup for polyuria and polydipsia can be tedious, time-consuming, expensive, confusing, and not without significant patient morbidity, especially in those cases with normal or near-normal blood work. This article focuses on the diagnostic approach and problems associated with diagnostic testing in patients with disorders of water balance.

We describe the complicated course of a rare pregnant woman with symptomatic Huntington disease (HD) and discuss multidisciplinary care issues that may be encountered. A 31-year-old gravida 2, para 1 with advanced HD was admitted at 30 weeks gestation for preterm labor. Her course was complicated by progressive cognitive and physical impairment, dysphagia, malnutrition, diabetes insipidus, aspiration pneumonia, chorioamnionitis, preterm delivery and pyelonephritis. Pregnant women with symptomatic HD may present multiple challenges requiring extensive multidisciplinary input.
