Splenectomized andnonsplenectomized dogs were experimentally infected with Babesia gibsoni. Infectivity of parasites was retained for 1 month in samples of blood kept at 4 C in a mixture with Alsever's, acid-citrate-dextrose (ACD), or ammonium-potassium oxalate solutions. When samples were slowly frozen to -70 C in a mixture with citrate solution, the parasites remained infective for 4 months. The average prepatent period was 3.3 days in splenectomized dogs and 4 days in nonsplenectomized dogs. Clinical signs were mild fever and anemia in nonsplenectomized dogs and fever, anemia, icterus, and rarely, hemoglobinuria in splenectomized dogs. Blood packed cell volume (PCV) decreased to as little as 11%, and total bilirubin increased to as great as 0.85 mg/dl. Latent parasitemia was still detectable in some dogs 135 days after the initial parasitemia. Gross pathologic changes mainly involved liver and spleen. Hepatic degeneration was always present.

From November 1970 to August 1974 small intestinal bypass was performed in 475 patients for morbid obesity with an operative mortality of 1.6%. Immediate postoperative complications were superficial wound infection (17 patients), pulmonary complications (seven patients), cardiac complications (five patients), wound dehiscence (nine patients), intestinal tract fistula (four patients), and miscellaneous complications (14 patients). Delayed complications included hypokalemia (28%), hypocalcemia (9%), anemia (11%), calcium oxalate urinary calculi (6%), gout (2%), and hepatic failure (1.4%). Fourteen patients died of late complications. Ventral incisional hernia occurred in 3% of the patients; failure to lose sufficient weight in 21%, all but one occurring in patients with end-to-side shunts. Thirteen end-to-side shunts have been converted to end-to-end shunts because of insufficient weight loss. A team concept is important in the handling of the morbidly obese. Small bowel bypass is effective in producing sustained weight reduction in these patients. Careful and continued study of these patients for the rest of their lives is of paramount importance.

The changes in the osmotic resistance of red blood cells (RBC), due to various pathological conditions like exposure to heat, anemia as well as the effect of storage and anticoagulants have been investigated. The results have shown that exposure to a temperature of 50 degrees C makes the red blood cells fragile to osmotic pressures. Also, red blood cells from the patients suffering from anemia exhibited decreased osmotic resistance. Storage upto 9 days showed a marginal increase in the osmotic fragility of the RBC and beyond that, there was no significant effect upto 15 days. Also, exposure to anticoagulants like citrate, ammonium oxalate, and EDTA increased the osmotic fragility of the cells. The present study shows that the various traumas investigated will affect the mechanical properties of the red blood cell membrane.

A 9-year-old castrated male domestic shorthair cat with dysuria, anorexia, vomiting, and lethargy was admitted to the veterinary teaching hospital. A large, firm mass was palpable in the ventral cervical region. Hypercalcemia, azotemia, and nonregenerative anemia were evident on serum biochemical analysis and CBC, and multiple uroliths were detected by abdominal radiography. At necropsy, light microscopy of the ventral cervical mass revealed a parathyroid adenocarcinoma. Light microscopy of sections of the kidneys revealed multifocal, chronic, lymphocytic/plasmacytic, tubulointerstitial nephritis, as well as moderate multifocal acute tubular necrosis. On quantitative analysis, the uroliths were composed of calcium oxalate. Determination of serum calcium concentration is indicated in cats with calcium oxalate urolithiasis to aid in detection of primary hyperparathyroidism.

We report a male patient with primary hyperoxaluria from childhood who survived more than 21 years on conventional haemodialysis. Despite the severity of his bone disease, he was married and actively employed up until 2 years before his death. His condition really worsened a few months before his death. He presented with only renal and bone involvement and had hardly any cardiovascular complications, that was probably a reason for his prolonged survival. Such an evolution is very unusual and we speculate that the length of haemodialysis sessions in addition to the large surface of the membrane probably contributed to such an outcome. During the time period on HD, anemia was transiently controlled by recombinant erythropoietin despite oxalate involvement of the marrow. He was refused a liver-kidney transplant and died from malnourishment at 43 years of age. To our knowledge, such an outcome has not yet been reported. It shows that careful prolonged hemodialysis sessions should be helped in admet patients without severe cardiovascular involvement.

A 63-year-old woman who had received hemodialysis therapy since she fell acute on chronic renal failure 4 years ago presented with multiple joint pain. Nephrocalcinosis was not detected by abdominal X-ray when hemodialysis therapy was initiated. Laboratory testing showed azotemia, anemia, hypoproteinemia and mild liver dysfunction but no liver cirrhosis. Biopsied bone tissue demonstrated numerous calcium oxalate crystal depositions. Laparoscopy revealed black liver in macroscopic view. Histological studies showed numerous lipofuscin-like dark brown granules were deposited in hepatocytes. The activity of alanine : glyoxylate aminotransferase (AGT) was less than 0.1 U/g in biopsied patient's liver tissue. Generally, clinical symptoms demonstrated by Japanese primary hyperoxaluria type I (PH-I) patients are milder than those of European patients. Some PH-I patients may successfully avoid urinary tract calcification unless they fall into oliguria by some other causes. The lipofuscin granules are most likely the source of the dark color. Massive deposition of the lipofuscin granules indicated that the duration of the liver metabolic abnormality had lasted for long time. Thus, black liver may be related to a mild form of PH-I.

We present the case of a young woman with end-stage renal disease secondary to primary hyperoxaluria type 1, who after 3 years and 6 months of maintenance hemodialysis, and despite intensification of the dialytic treatment, developed severe livedo reticularis in her extremities leading to ischemic cutaneous ulcerations, necessitating continuous intravenous infusion of narcotics for pain control. She received a liver transplant after native hepatectomy. However, due to positive crossmatch, she could not receive a kidney from that donor. After transplantation, following serial serum oxalate levels, the hemodialysis regimen was safely reduced from 4 h daily to 3 h three times weekly. Over the course of 6 weeks after liver transplantation, her livedo reticularis resolved, the ischemic ulcers markedly improved, she was weaned off all pain medications, and her erythropoietin-resistant anemia resolved. Our results suggest that in patients with primary hyperoxaluria type 1, who have received a liver transplant and are on maintenance hemodialysis, after serial serum oxalate determinations, some may safely be changed to a thrice-weekly maintenance hemodialysis regimen. Moreover, with this regimen the complications of systemic oxalosis can reverse.

Disulone (dapsone + ferrous oxalate) is a sulphone marketed in France since 1958 and authorized in P. Carinii prophylaxis in HIV+ cotrimoxazole intolerant patients, bullous dermatosis, leprosy and polychondritis. Between 1983 and 1998, 249 adverse reactions were reported to French pharmacovigilance centres and Aventis, the manufacturer. Every side-effect was reviewed and the causal relationship was assessed on the basis of the French method for causality assessment. Main side-effects were divided as follows: 117 blood dyscrasias (generally neutropenia and agranulocytosis, rarely methaemoglobinaemia, haemolysis, macrocytosis, anaemia, aplastic anaemia, haemochromatosis and sulphaemoglobinaemia); 29 hypersensitivity syndrome; 39 cutaneous reactions, generally rash; 27 liver injuries (cholestatic, cytolytic and mixed hepatitis); 27 neurological and psychiatric side-effects including 7 axonal neuropathy; 10 gastrointestinal effects, generally nausea and vomiting. Five deaths were reported (4 septicaemia including one case not due to dapsone and 1 digestive bleeding due to underlying disease). In the other cases the outcome was favourable. The results were compared with the published references. It would seem to be important to reinforce information to prescribers about the possible serious adverse reactions with dapsone, particularly hypersensitivity syndrome and agranulocytosis, that can cause death if the drug is not stopped in time.

The three platinum derivatives currently available share many pharmacokinetic and pharmacodynamic (PK-PD) properties but present also some distinct characteristics, due to their structural differences. They result in different systemic PK-PD and metabolic behaviour and toxicity profile. Oxaliplatin is quickly transformed into dach-platinum, the active metabolite, by loosing oxalate chain. Eighty to eighty-eight per cent of platinum are bound to proteins, as for cisplatin, whereas carboplatin is less reactive. Cisplatin and oxaliplatin active metabolites, i.e. monoaquo platin and dach-platin quickly react with small proteins with sulfhydryl groups, such as glutathione, cysteine and methionine, and then with high molecular weight proteins, such as albumin and gammaglobulins through covalent link. Thus, their terminal half lives are long, about ten days, but no platinum accumulation has been reported in plasma with oxaliplatin, whereas after cisplatin administration, both total and ultrafiltrable platinum progressively accumulate in plasma. This difference may play a role in the lack of oxaliplatin nephrotoxicity and its more delayed and reversible neurotoxicity. On the other hand, carboplatin is more stable, less bound to proteins and is largely excreted inchanged in urine. This can explain that it passes more easily through the blood brain barrier. Erythrocytes represent an important deep compartment, especially for oxaliplatin, a little bit less for cisplatin. Oxaliplatin is trapped in erythrocytes through a covalent binding to globin. There, its half life is identical to that of erythrocytes. According to certain authors, this trapping would be involved in the incidence of anemia. On the contrary, carboplatin is quickly extruded from erythrocytes. The three derivatives kinetics in plasma present a wide interindividual variability, resulting in differences in term of toxicity and efficacy. For the three of them, plasma clearance is correlated to creatinine clearance, but only carboplatin dosage can be individually adjusted, based on creatinine clearance measurement, thanks to its simple renal excretion, due to exclusive glomerular filtration, and after Calvert's, Egorin's and Chatelut's population kinetics studies. Cisplatin renal excretion is more complex, combining reabsorption and secretion processes. Therefore, individual dosage adjustment needs platinum concentration measurement in plasma, but there is no general agreement on the platinum species to measure, ultrafiltrable or bound. Oxaliplatin is too recent in clinical practice and still lacks of PK-PD data. These characteristics can help us for a better knowledge of the three platinum derivatives clinical properties, both in term of kinetics, behaviour and toxicity.

Among human bicarbonate transporters, two major gene families encode Na-independent Cl(-)/HCO(3)(-) exchangers: the SLC4 anion exchanger (AE) family, and the SLC26 "sulfate permease" anion transporter family. The SLC4 AE family contains at least three genes, and comprises a subfamily within the larger and phylogenetically more ancient bicarbonate transporter superfamily that includes the Na bicarbonate cotransporters (NBC) and the Na-driven Cl/base exchangers. Mutations in the human AE1 gene cause autosomal dominant spherocytic anemia and distal renal tubular acidosis of both dominant and recessive forms. Anemia is also associated with AE1 mutations in mouse, cow, and zebrafish. Naturally occurring mutations in the human AE2 and AE3 genes have not been detected. The SLC26 family in humans consists of at least 10 members, and includes anion exchangers which exchange chloride for bicarbonate, hydroxyl, sulfate, formate, iodide, and/or oxalate. Mutations in three of these genes cause hereditary disease, including chondrodysplasia (SLC26A2, DTD), diarrhea (A3, down-regulated in adenoma/chloride-losing diarrhea protein: DRA/CLD), and goiter/deafness syndrome (A4, pendrin). Little is known about the acute regulation of these modulators of intracellular and compartmental pH and volume.
