A patient with transfusion-dependent thalassemia was undergoing home intravenous desferrioxamine (DFX) treatment by means of a totally implanted system because of his poor compliance with the nightly subcutaneous therapy. Due to an accidental malfunctioning of the infusion pump, the patient was inadvertently administered a toxic dosage of the drug which caused renal insufficiency. Given the progressive deterioration of the symptoms and of the laboratory values, despite adequate medical treatment, a decision was made to introduce haemodialytical therapy in order to remove the drug and therapy reduce the nephrotoxicity. From the results obtained, haemodialysis can therefore be suggested as a useful therapy in rare cases of progressive acute renal failure caused by desferrioxamine.

A double-blind, randomized, dose-finding, phase II mefloquine trial was carried out in 147 adult male patients suffering from acute, uncomplicated, falciparum malaria and admitted to the Hospital for Tropical Diseases, Bangkok, between January 1980 and April 1981. Mefloquine was administered as a single oral dose of 500, 750, or 1000 mg (base) in the form of the hydrochloride. The clinical and parasitological responses were satisfactory with all three dosage regimens. The cure rates for the 1000-, 750-, and 500-mg doses were 100%, 92.5%, and 95% respectively, over an observation period of 63 days.The side-effects, which were transient and generally mild, included nausea, vomiting, and diarrhoea. No significant changes were noted in haematological or biochemical parameters in any of the three groups. Sinus bradycardia, which started 4-7 days after drug administration and lasted for a few weeks, was seen in 10 patients. It was symptomless and needed no treatment.Acute brain syndrome was observed in one patient on day 21 after receiving a 1000-mg dose of mefloquine.Mefloquine was well tolerated in one case of acute renal failure, in 10 cases of moderately severe malaria with jaundice, in 13 cases with glucose-6-phosphate dehydrogenase deficiency, and in one case of thalassaemia.Mefloquine showed no effect on either gametocytes of Plasmodium falciparum or tissue forms of P. vivax.Mefloquine hydrochloride was found to be an effective drug for the treatment of falciparum malaria and tended to produce a more rapid clinical and parasitological response at the highest tested dose of 1000 mg (base).

Advanced renal failure occurred in nine adult sickle cell disease patients. There were six men and three women with a mean age of 38.6 years. Eight patients had homozygous SS disease, one had sickle cell thalassemia. Three patients had acute renal failure from which they partially recovered. Six developed endstage kidney disease requiring dialysis. Two of these received a kidney transplant, and there was one death in the immediate postoperative period. Angina pectoris, hyperkalemia, and severe anemia complicated chronic dialysis, suggesting that early transplantation should be considered for sickle cell anemia patients with renal failure.

We report an unusual case of transfusion-transmitted malaria which remained undiagnosed for several months in an Italian woman splenectomised and polytransfused for thalassaemia major. The infecting species was Plasmodium malariae, and the patient developed acute renal failure, severe thrombocytopenia, and hepatic failure. Treatment with chlorochine was followed by a slow, but complete recovery of renal function.

Advances in hematopoietic stem cell transplantation (HSCT) for beta-thalassemia major make the long-term outcome of these patients very important. Few data on long-term renal function of thalassemia patients are available. We evaluated the renal function in children after successful allogeneic HSCT for beta-thalassemia. Twenty-nine patients were included; the mean age at HSCT was 4.9 years. Mean follow-up time was 7.6 years. After HSCT, two patients developed acute renal failure and two had graft versus host disease. At last follow up, height standard deviation score (SDS) remained the same, but weight SDS had improved. Mean hemoglobin was 12.5 g/dl, and serum ferritin level was 545 ng/ml. All children had normal estimated glomerular filtration rate (GFR). One patient had hypertension and proteinuria, 10 years after HSCT. When comparing 39 children of the same age with beta-thalassemia of similar disease severity but who had not experienced HSCT, we found that the parameters of renal tubule function were better in patients that had undergone HSCT, as demonstrated by urine protein level (0.36 mg/mg creatinine vs 3.03 mg/mg creatinine, P < 0.001), osmolality (712 mosmol/kg vs 573 mosmol/kg, P = 0.006), N-acetyl-beta-D: -glucosaminidase (17.7 U/g creatinine vs 42.9 U/g creatinine, P = 0.045), and beta 2 microglobulin (0.09 microg/mg creatinine vs 0.13 microg/mg creatinine, P = 0.029). This study showed a low incidence of long-term renal impairment after HSCT and indicated that renal tubule function may be better in beta-thalassemia patients after HSCT.

Perioperative management of a child with sickle-cell disease requires close collaboration between hematologist, surgeon and anesthetist. The level of preoperative preparation must consider both the surgical risk and the impact of the disease. Preoperative hydration and blood transfusion are the most important part of preoperative management. Anesthetic technique is not as important as preoperative preparation, management of stress and anxiety, and optimization of intraoperative physiological parameters (oxygenation, acid-base balance, tissue perfusion, normothermia). Pain management must be optimal for these children with increased needs of analgesic. Preoperative assessment of a child with thalassemia must include evaluation of the impact of chronic hemolytic anemia and iron overload induced by repeated transfusions. The most important factor in the management of a child with glucose-6-phosphate dehydrogenase deficiency is to avoid exposure to oxidative stressors. Outpatients should be informed of the risk of hemolytic crisis, and free hemoglobin in the urine should lead to discontinuation of drugs associated with hemolysis and to maintenance of urine output to prevent acute renal failure.
