Thirteen leukemic patients with disease refractory to conventional chemotherapy were treated with 1.0 to 7.5 g/m2 of Cytosine Arabinoside (Ara-C) over 29 drug cycles. Drug infusions were spaced at 12-hour intervals; a maximum of four doses was administered over 36 hours. After single dose tolerance had been established, three or four dose cycles were given at 2- to 30-day intervals. There were three partial remissions (PR) and one complete remission (CR) in a treatment group of four patients with AML, five with ALL, two with lymphoma converted to leukemic phase, one CML in blast crisis, and one promyelocytic leukemia. Five of the patients were septic and considered terminally ill at the time of treatment. All other patients had evidence of drug responsiveness. The nadir of the white count occurred from 3 to 12 days after treatment, with subsequent recovery of the peripheral granulocyte count between days 12 and 28. Toxicity included nausea and vomiting (GI symptoms) in twelve patients, central nervous system (CNS) disturbances in eight patients, one episode of inappropriate antidiuretic hormone syndromes (SIADH), one of hyperuricemia, and fever in eleven patients. There was no evidence of hepatic or renal dysfunction. These high doses of Ara-C appear useful for treatment of patients with refractory leukemia. Hospitalization is brief and toxicity acceptable.

A case of transient nephrogenic diabetes insipidus occurred in late pregnancy, the first associated with biopsy-proven hepatitis. Five previously reported cases occurred in pregnancy. All six patients demonstrated similar but transient signs, symptoms and laboratory abnormalities suggesting a syndrome peculiar to pregnancy. The characteristics of this syndrome are elevated liver function studies, decreased renal function, hyperuricemia and transient vasopressin-resistant diabetes insipidus.

A 29-year-old nullipara was admitted at 31 weeks' gestation because of toxemia. She noted gradually polyuria, severe thirst, malaise, nausea and anorexia. A water-deprivation test and administration of aqueous vasopressin confirmed the diagnosis of nephrogenic diabetes insipidus. At 33 weeks' gestation, blood chemistry studies revealed moderately elevated transaminase levels and hyperuricemia. Male twins were delivered by vacuum extraction at 35 weeks' gestation. After delivery, she became drousy and icterus appeared. Acute hepatic failure with marked hyperuricemia was diagnosed. She was treated with glucose solution with glucagon and soluble insulin, branched chain amino acids, gabexate mesilate, lactulose and famotidine. Her consciousness cleared rapidly and all laboratory data became normal by 15 days postpartum. The urine volume was about 5 liters per day from the first to sixth postpartum day. The diuresis decreased after the eighth postpartum day. Rare pregnancy complicated by transient nephrogenic diabetes insipidus and acute hepatic failure is discussed.

Diminished glomerular filtration rate, proteinuria, and large hypercellular congested glomeruli with segmental sclerosis are found in late survivors with cyanotic congenital heart disease (CCHD). Hyperuricemia is common, acute gouty arthritis is less common than uric acid levels would predict, and overt tophaceous deposits of uric acid are exceptional. The role of the kidney in causing the basic biochemical disturbances, and the relative importance of impaired urate excretion vs urate overproduction have not been established. Accordingly, we reviewed the courses of two index patients and prospectively studied eight additional CCHD patients from 28 years to 46 years old with mean hematocrits of (62 +/- 10%). Plasma creatinine concentration was normal (0.9 +/- 0.1 mg/dl) yet glomerular filtration rate was mildly reduced to 93 +/- 14 ml/min as measured by creatinine clearance and to 81 +/- 6 ml/min as measured by 111In DTPA. Three patients had significant proteinuria and one was nephrotic. Plasma uric acid concentration was high in all but one (8.2 +/- 2.1 mg/dl), mean 24 hr uric acid excretion was normal (564 +/- 221 mg), and fractional uric acid excretion was relatively low (6.3 +/- 2.6%). The two patients with highest plasma uric acid levels (12.0 and 10.2 mg/dl) had the lowest fractional excretions (2.8% and 4.0%). Both of these patients had diminished capacity to excrete a water load (38% and 27%/4 hr) and to maximally concentrate urine (520 and 635 mOsm/kg after water deprivation and vasopressin). In conclusion, high plasma uric acid levels in late survivors with CCHD are secondary to inappropriately low fractional uric acid excretion, not to urate overproduction.(ABSTRACT TRUNCATED AT 250 WORDS)

Among the factors, which may influence on the uric acid metabolism, the excess or deficiency of some hormones apparently induces the abnormal serum uric acid level. We described hyperuricemia and hypouricemia associated with endocrine disorders. Hyperuricemia due to the increased production of uric acid is observed in myopathy associated with hypothyroidism, hyperthyroidism or hypoparathyroidism. Hyperuricemia due to the decreased renal uric acid clearance is associated with hypopituitarism, hypothyroidism, hyperparathyroidism, central diabetes insipidus, nephrogenic diabetes insipidus, Bartter syndrome, and diabetic ketoacidosis. Hypouricemia due to the increased renal uric acid clearance is associated with hypoparathyroidism, primary aldosteronism and inappropriate secretion of antidiuretic hormone (SIADH).

The acute tumor lysis syndrome (ATLS) is characterized by the rapid development of hyperuricemia, hyperkalemia, hyperphosphatemia, and acute renal failure (ARF). Hematologic malignancies are responsible for most cases of ATLS. Control of hyperuricemia and the achievement of a high urine flow are the mainstays of prevention. Urinary alkalinization should be performed only when hyperuricemia is present. Hypercalcemia occurs in 10% to 20% of patients with cancer at some time during the disease course. Parathyroid hormone-related protein (PTHrP) is the most common mediator of humoral hypercalcemia of malignancy (HHM), while local osteolysis is the principal mechanism in patients with bone metastasis. Hydration with saline and administration of pamidronate control hypercalcemia in most patients. Hyponatremia with an increase in total-body salt and water content, manifested as edema and/or ascites, is the most common electrolyte abnormality in cancer patients. Hyponatremia due to salt depletion may occur in patients who receive cisplatin. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) may occur in association with cancer of the lung, after high-dose cyclophosphamide, and during vigorous fluid administration in patients with chemotherapy-associated emesis. Lactic acidosis without tissue hypoperfusion may be seen in patients with extensive liver metastasis or with certain hematologic malignancies. In the latter cases, lactate levels parallel disease activity and chemotherapy often leads to resolution of the lactic acidosis. Idiopathic hyperammonemia has been described after intensive chemotherapy for hematological malignancies and following bone marrow transplantation.

Hyponatremia is seen in 40% to 60% of hospitalized acquired immune deficiency syndrome (AIDS) patients. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) and volume contraction are the most common causes. The serum uric acid level can be used to distinguish between these two causes of hyponatremia. Hypouricemia is the rule in SIADH, whereas hyperuricemia commonly accompanies volume contraction. This report presents an AIDS patient with SIADH and normouricemia secondary to pyrazinamide and ethambutol.

Dehydration, a condition that characterizes excessive loss of body water, is well known to be associated with acute renal dysfunction; however, it has largely been considered reversible and to be associated with no long-term effects on the kidney. Recently, an epidemic of chronic kidney disease has emerged in Central America in which the major risk factor seems to be recurrent heat-associated dehydration. This has led to studies investigating whether recurrent dehydration may lead to permanent kidney damage. Three major potential mechanisms have been identified, including the effects of vasopressin on the kidney, the activation of the aldose reductase-fructokinase pathway, and the effects of chronic hyperuricemia. The discovery of these pathways has also led to the recognition that mild dehydration may be a risk factor in progression of all types of chronic kidney diseases. Furthermore, there is some evidence that increasing hydration, particularly with water, may actually prevent CKD. Thus, a whole new area of investigation is developing that focuses on the role of water and osmolarity and their influence on kidney function and health.

The prevalence of juvenile-onset gout has been increasing. Hereditary factors and secondary diseases should be considered in these patients. Adipsic diabetes insipidus (ADI) is characterized by arginine vasopressin (AVP) deficiency, which results in hypotonic polyuria, and dysfunction of thirst osmoreceptors, which results in failure to generate a thirst sensation in response to hypernatremia. We herein report a case of a boy with gouty arthritis, refractory hyperuricemia, prominent hypernatremia, a high creatinine concentration, and a history of surgery for a hypothalamic hamartoma. The patient was diagnosed with central diabetes insipidus after endocrine evaluation. Because he never had symptoms of thirst, the final diagnosis was corrected to ADI. This is the first report of gout due to chronic ADI in an adolescent. Volume contraction due to ADI might be one cause of hyperuricemia and renal impairment in such patients. Moreover, AVP deficiency might directly lead to low urate clearance due to the lack of vasopressin receptor 1 stimulation. Lack of polydipsia and polyuria may delay the diagnosis of ADI and lead to severe complications of a chronic hyperosmolar status. Sufficient and effective establishment of normovolemia is critical for these patients.
