BACKGROUND. Exposure of pregnant women to angiotensin converting enzyme inhibitor may have side effects on the fetus or newborn, mainly oligoamnios and impaired renal function. CASE REPORT N zero 1. A 34 year-old woman was given enalapril from the onset of her pregnancy because of hypertension from the age of 18 years. Oligoamnios was diagnosed in the fetus on gestational week 28; enalapril was then replaced by nifedipine but this drug was badly tolerated so that the woman was again given enalapril 8 days later. The baby (1700 g) was born by cesarean section at gestational week 34 because of acute distress syndrome; he developed hypotension, anuria, generalized oedema and was placed in intensive care. Treatment included ventilation, sympathomimetic agents, and diuretics. An exchange-transfusion followed by peritoneal dialysis was performed a few hours later. Renal function returned to normal between the 3rd and 5th day. Unilateral kidney hypoplasia was diagnosed at the age of 2 years. CASE N zero 2. A 24 year-old woman was given enalapril at the third trimester of a twin pregnancy. Delivery was full term at 37 weeks. The first baby, a boy weighing 2610 g, suffered from hypoglycemia and vomiting followed by hypotension and oliguria that required exchange-transfusion and repeated peritoneal dialysis. This boy has developed moderate chronic renal failure and hypertension. The second baby, a girl weighing 2,165 g, suffered from respiratory distress syndrome followed by hypotension and oliguria, but her renal function returned to normal within a few days. CONCLUSIONS. The use of angiotension converting enzyme inhibitor by pregnant women places the fetus at severe risk: treatment with this type of drug should be stopped as soon as pregnancy is confirmed.

Renal failure secondary to CDDP is due to acute tubular necrosis and is usually reversible. We report 4 cases of definitive renal failure secondary to administration of cisplatin (CDDP). Three women and one man, mean age 40 +/- 8 years (24 to 64 years), at onset of dialysis are reported. They had received 1 to 4 courses of CDDP for an endometrial carcinoma (n = 2), a breast carcinoma or a thymoma. The mean total dose of CDDP was 447 +/- 169 mg (160 to 900 mg). There was no additional nephrotoxic drug. Before treatment serum creatinine concentration was normal (77 +/- 7 mumol per liter) in all patients. In 2 cases dehydration (due to vomiting and use of mannitol) occurred during CDDP treatment. One patient was treated 30 days after a nephrectomy. At the onset of dialysis, renal ultrasound was normal. In 3 cases dialysis was necessary within 15 days following chemotherapy. In one case renal function deteriorated progressively to end stage renal failure 12 months after CDDP treatment. Dialysis was performed in 3 cases by hemodialysis and in one patient by peritoneal dialysis. All patients remained more than 6 months on dialysis. Three patients died from their cancer. One patient, being considered cured from his thymoma, is currently being evaluated for a kidney transplantation. Our observations outline the potential severity of CDDP nephrotoxicity. Systemic hydration with serial serum creatinine measurements are mandatory during and after CDDP administration these patients.

The medical records of 101 dogs with acute pancreatitis, diagnosed on the basis of medical histories of acute vomiting, with serum lipase or amylase activity greater than the reference range, or with gross signs of pancreatitis at surgery or histopathologic evidence at necropsy, were evaluated to identify potential risk factors for the development of acute pancreatitis. Age, sex, and breed of dogs with acute pancreatitis were compared with those from a reference population of 100 dogs admitted for other medical emergencies during the same period. Analysis of multiple regression models indicated that dogs > 7 years old were at increased risk for acute pancreatitis. Spayed dogs and castrated male dogs had an increased risk, compared with that of sexually intact males. Similarly, terrier and nonsporting breeds appeared to be at higher risk of developing acute pancreatitis than were other breed types. Most dogs in this study (63/101) had intercurrent diseases, including diabetes mellitus (n = 14), hyperadrenocorticism (n = 12), chronic renal failure (n = 8), neoplasia (n = 17), congestive heart failure (n = 6), and autoimmune disorders (n = 5). Fourteen dogs had undergone anesthesia or surgery in the week before admission; only 3 had undergone abdominal procedures. Recent medication use was listed in 52 of 101 cases. Antibiotics (n = 18) and corticosteroids (n = 18) were most frequently described. Anticancer chemotherapeutic agents (n = 5) and organophosphate insecticides (n = 5) also were listed.(ABSTRACT TRUNCATED AT 250 WORDS)

Glomerulonephritis (GN) is a leading cause of chronic renal failure in dogs. However, little is known about the efficacy of available treatment options for GN in this species. The purpose of this study was to determine the effects of cyclosporine (Cy) administration on the outcome of naturally occurring GN in dogs. Thirteen dogs from 4 institutions were included in the study. Randomization of dogs into placebo-versus Cy-treated groups was stratified according to initial morphological diagnosis and contributing institution. Seven and 6 dogs were assigned to be given placebo or Cy, respectively. The initial Cy dose of 10 mg/kg every 24 hours was adjusted to maintain 24-hour trough, whole blood Cy concentrations between 250 and 400 ng/mL. There were no statistically significant differences between placebo- and Cy-treated groups with respect to serum total protein, albumin, urea nitrogen and creatinine, and plasma protein concentrations; platelet count; urine protein-creatinine ratio; endogenous creatinine clearance; 24-hour urine protein concentrations; or 24-hour urine protein-endogenous creatinine clearance ratio. However, PCV was significantly lower in the Cy-treated group. Decreased appetite, diarrhea, vomiting, weight loss, involuntary shaking, and thrombocytopenia were noted in both treatment groups; however, clinical signs in Cy-treated dogs subjectively were more severe. One Cy-treated dog developed gingival hyperplasia.(ABSTRACT TRUNCATED AT 250 WORDS)

Growth retardation commonly complicates chronic renal failure in children. Although the etiology of this growth impairment is multifactorial, inadequate nutrition is considered an important cause in infants and young children. An "aggressive" nutritional approach has been repeatedly suggested in children with early onset chronic renal failure and poor feeding habits, but the possibility of inducing catch-up growth by energy supplementation is still controversial. The nutritional effects of a long-term, home-based enteral feeding program were studied in two infants and three children with moderate to severe chronic renal failure and impaired growth associated with persistent anorexia. In all patients, renal failure had developed during the first year of life due to congenital diseases. Enteral feeding was performed at home, during the night, through a silicone rubber nasogastric tube. The treatment lasted for 1 year. The energy intake ranged between 101% and 116% of the recommended dietary allowance (RDA), and the protein intake between 96% and 113% of the RDA in all patients but one, in whom proteins were restricted to 75% of the RDA. All children showed a substantial improvement in deviation score for both weight (mean increase +1.76), height (mean increase +1.52) and in the general metabolic condition, irrespective of age, severity of osteodystrophy, or degree of renal failure. The treatment was well tolerated and, apart from a few episodes of vomiting, no complications arose during the treatment. Tube feeding may be an effective therapeutic option for overcoming malnutrition when chronic renal failure is associated with persistent anorexia. In infants and young children, growth retardation can be opposed and catch-up growth obtained.

Diet and nutrition are integral to the management of individuals with renal disease. Uremia engenders anorexia, nausea, meat aversion, and emesis, disturbances that ultimately reduce appetite and cause weight loss and malnutrition. Protein restriction can alleviate these uremic symptoms and improve patient health and vigor, but overly zealous protein restriction may, itself, produce malnutrition. This is particularly likely when energy intake is restricted by either design or anorexia. End-stage renal disease patients require renal replacement therapy for survival, and although dialysis is life sustaining, it neither replaces normal kidney function nor obviates the need for dietary management. In this setting of controlled, persistent uremia, undernutrition can develop surreptitiously. Dialysis physicians have long regarded malnutrition as a sign of uncontrolled uremia and failing health. This supposition has now been validated by epidemiologic studies demonstrating that serum albumin and protein catabolic rate (PCR) discriminate between dialysis patients at high and low risk of death or illness. This correlation of undernutrition with health and survival persists across wide ranges of age, medical diagnoses, and dialysis prescriptions. Because PCR is readily measured using urea kinetic analyses, it has been promoted as a patient monitoring tool and under steady-state conditions it is a reliable method of determining protein intake. Although a single PCR measurement does not integrate day-to-day dietary and metabolic fluctuations and contains an inherent uncertainty of +/- 20%, sequential measurements can be used to assess changes in an individual's dietary protein intake. PCR defines nitrogen losses and, when normalized to a realistic index of metabolic activity (metabolically active body size), it can disclose subtle individual variances in nitrogen utilization. These normalized protein catabolic rates (NPCR) do not, however, measure or describe overall nutrition. The normalization schemes employed are based on population averages and only approximate an individual's true metabolic activity. Thus, using NPCR to define nutritional needs can result in overfeeding obese and underfeeding wasted subjects. Instead, nutritional adequacy should be defined by clinical inspection and comparison with defined standards. Once that state is defined, and desirable protein and calorie intakes are determined, NPCR can be used to monitor the patient's ability to maintain homeostasis.

Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often ineffective. Gastritis, duodenitis and peptic ulcer are often found in adults with CRF on regular haemodialysis and following renal transplantation. Despite persistent hypergastrinaemia, gastric acid secretion is decreased rather than increased in most of these patients, and active peptic disease appears to be promoted by the removal of the acid output inhibition (neutralisation of gastric acid by ammonia) that follows active treatment. Helicobacter pylori, on the other hand, does not seem to play a significant role in the pathogenesis of peptic disease in CRF. Gastro-oesophageal reflux has been found in about 70% of infants and children with CRF suffering from vomiting and feeding problems, and thus appears to be a major problem in these patients. In a number of symptomatic patients with CRF, gastric dysrhythmias and delayed gastric emptying have also been found; hence there appears to be a complex disorder of gastrointestinal motility in CRF. Serum levels of several polypeptide hormones involved in the modulation of gastrointestinal motility [e.g. gastrin, cholecystokinin (CCK), neurotensin] and the regulation of hunger and satiety (e.g. glucagon, CCK) are significantly raised as a consequence of renal insufficiency, and can be reverted to normal by renal transplantation. Furthermore, several other humoral abnormalities (e.g. hypercalcaemia, hypokalaemia, acidosis, etc.) are not uncommon in CRF. By directly affecting the smooth muscle of the gut or stimulating particular areas within the central nervous system, all these humoral alterations may well play a major role in the gastrointestinal dysmotility, anorexia, nausea and vomiting in patients with CRF. Specific pharmacological and nutritional interventions should thus be considered for the treatment of vomiting and feeding problems in CRF.

A 25-year-old man developed nausea, vomiting, severe headache, and confusion. He had a past history of hyperuricemia and mild renal dysfunction. On admission he had somatic growth retardation, hypertrichosis, and bilateral auditory impairment. A cranial CT scan showed a small area of low density in the left temporal lobe and cerebellar atrophy. Five days later, he developed right homonymous hemianopia, sensory aphasia, and sensory inattention, and a new, large area of low density in the left occipital lobe on a cranial CT scan. On laboratory examination, lactate, pyruvate, and the lactate-to-pyruvate ratio were elevated in both the serum and cerebrospinal fluid. The biopsied muscle showed ragged red fibers and strongly SDH-reactive blood vessels. Gene analysis revealed the presence of the A 3243 G point mutation of the mitochondrial tRNA(Leu) gene in his blood leucocytes and muscle. Serum concentrations of BUN and creatinine were elevated to 46 mg/dl and 2.2 mg/dl, respectively. Creatinine clearance was 14.1 ml/min. An abdominal CT scan disclosed atrophy of his left kidney with subcapsular calcification and the findings of his abdominal ultrasonography were compatible with chronic renal failure. His mother, who suffered from renal failure and became dialysis dependent in her late forties also bore the A 3243 G mutation of the mitochondrial tRNA(Leu) gene in her circulating leucocytes. Though the association between MELAS and renal dysfunction still remains obscure, we speculate that renal failure can be a manifestation of MELAS.

Fifty-two patients with chronic renal failure undergoing hospital haemodialysis were given a single bolus dose of tinzaparin (Innohep, Leo Laboratories, UK) into the arterial side of the dialyser, for up to 43 consecutive dialyses. The mean tinzaparin dose at the beginning was 2,139 IU anti-Xa and at the end 2,186 IU anti-Xa. Overall, tinzaparin proved a satisfactory anticoagulant for 1,370 (96.0%) out of 1,427 dialyses. Significant clot formation was prevented in 1,326 (92.8%) out of 1,429 dialyses. The clinically effective dose was associated with a mean plasma anti-Xa activity 1 h after dosing of 0.4 IU/ml and suppressed fibrinopeptide A formation for up to 4 h. Bleeding, from the skin or mucous membranes, was recorded at 27 (1.9%) of 1,408 dialyses. Prolonged fistula bleeding on completion of dialysis was recorded on only 20 occasions. Other haemorrhagic events included haematemesis, bruising and subconjunctival haemorrhage (each in 1 patient) and epistaxis (2 patients). Three patients died during the study of causes considered unrelated to tinzaparin therapy, myocardial infarction (2 patients) and multiple myeloma. Other adverse events reported included vomiting (3 patients) and hypotension (3 patients). Three patients ceased treatment due to haematemesis, prolonged bleeding from fistula puncture and thrombosis of the arteriovenous access, respectively. A small, but statistically significant, increase within the normal reference range was recorded in the mean values for aspartate aminotransferase and alanine aminotransferase.

We describe the features of intestinal strongyloidiasis in six patients; five of them were immunosuppressed (four on corticosteroids, one with chronic renal failure). Vomiting and diarrhea were the predominant symptoms. Duodenal mucosa on endoscopy varied from normal to severe ulceration. Albendazole 400 mg/day for two weeks was effective. This condition should be considered in immunosuppressed individuals with gastrointestinal symptoms, especially since these symptoms may be mistakenly attributed to the underlying disease.
