A 1-3/12-year-old Turkish boy born of consanguineous parents was hospitalized in poor general condition with disorientation, hepatosplenomegaly, and rickets. Laboratory tests showed pronounced symptoms of hepatic dysfunction, rickets, and Fanconi's syndrome with acidosis. The diagnosis juvenile type I tyrosinemia was based on the anamnesis, hepatorenal symptoms, and elevated tyrosine and methionine blood levels as well as the pathognomic findings of heavy succinylacetonuria and absent fumarylacetoacetase activity in the fibroblasts. Etiology, pathobiochemistry, clinical symptoms, differential diagnosis, and therapy of this rare autosomal-recessive inherited metabolic disease were discussed.

Clinical, pathologic, and biochemical data are reported in two male infants who had rapidly progressive renal failure, enlarged kidneys, hepatosplenomegaly, and fat malabsorption. One infant, studied prior to the onset of significant renal insufficiency, manifested renal Fanconi syndrome, hyperparathyroidism, and marked hypocalcemia. After a brief period of dialysis, both received renal transplants. Neither has clinical evidence of reoccurrence of the renal disorder in the transplant, but both still have hepatic abnormalities. Morphologic features present in both patients include a renal lesion characterized by tubulointerstitial injury with a tubulocystic component and hepatic abnormalities with bile duct proliferation, portal fibrosis, and inflammation. These cases do not readily conform to any single published diagnostic category, including nephronophthisis-congenital hepatic fibrosis or infantile polycystic kidney disease, and appear to be unique.

We report a unique case of brucellosis transmitted by BMT. An 8-year-old boy with the diagnosis of Fanconi's anemia received an allogeneic BMT from his HLA-identical sibling. Routine culture from the infused marrow suspension grew Brucella abortus on day +4 post BMT. Spiking fevers occurred on days +2 and +16. The first febrile episode responded to broad-spectrum antibiotic therapy. However, the second episode did not. B. abortus was isolated from blood cultures taken during the second febrile episode. The Brucella agglutination titer was negative. Antibiotic therapy with oral doxycycline and i.v. gentamycin was successful with no recurrence of infection during 13 months of follow-up. The donor's blood culture was also positive for B. abortus and Brucella antibodies were detectable at 1:320 titer when he presented with fever and hepatosplenomegaly on day +32. We emphasize the need to consider brucellosis in patients undergoing BMT. We suggest that donor and recipient be evaluated for brucellosis especially in countries where the incidence of this infection is relatively high.

Renal Fanconi syndrome developed rapidly in a 3-year-old Moroccan girl with established lysinuric protein intolerance. She was hospitalized because of lowered consciousness, uncoordinated movements and hepatosplenomegaly after a febrile period. Laboratory investigations revealed plasma ammonia 270 micromol/L (normal <70 micromol/L), ferritin 159 micromol/L (normal 2-59 micromol/L), LDH 1180 U/L (normal 26-534 U/L). LPI was diagnosed based on the findings of reduced plasma ornithine, arginine and lysine, and an increased level of glutamine. Urinary orotic acid (645 micromol/mmol creatinine; normal <3.6) was strongly increased. A defect in the SLC7A7 amino acid transporter was established (homozygous c.726G > A mutation). Detailed renal function tests including an acid challenge test, bicarbonate loading, and tubular maximal reabsorption of glucose showed complex tubular dysfunction. No evidence of respiratory chain defects was found in muscle or kidney tissue. No morphological abnormalities were demonstrated in the mitochondria. Ultrastructural analysis of proximal tubular cells showed vacuolization and sloughing of the apical brush border (Fig. 1). Renal involvement in LPI has only been described in a few reports; however, no detailed studies of the renal acidification mechanism were performed. Our patient had evidence of a full-blown Fanconi syndrome. Surprisingly, a metabolic acidosis was found with a moderately increased serum anion gap combined with repeatedly normal plasma organic acid values. This finding is in contrast with the diagnosis of renal tubular acidosis. Patients with hyperlysinaemia have a similar heavy load on the renal tubules; they never develop a renal Fanconi syndrome. Therefore, we consider the intratubular accumulation of lysine an unlikely candidate for the development of the renal Fanconi syndrome.

A-14-year old boy, presented with a short history of excessive thirst and increased urine output. Clinical examination showed pallor, generalized lymphadenopathy and hepatosplenomegaly. For evaluation of his polyuric state he underwent routine laboratory investigations, including renal function test, acid-base studies, urine analysis. Blood tests suggested hypokalemia, hypouricemia, hypocalcemia and hyperchloremia with normal liver and kidney function tests. The arterial blood gas analysis was suggestive of normal anion gap metabolic acidosis. Urine analysis was suggestive of hyperuricosuria, hypercalciuria and glycosuria with a positive urine anion gap. His hemogram showed pancytopenia with differential count showing 88% blasts. Bone marrow examination and flowcytometry confirmed the diagnosis of B cell acute lymphoblastic leukemia. Hence this case was atypical and very interesting in the sense that the Fanconi syndrome is very rare to be an initial presenting feature of acute lymphoblastic leukemia. The patient was started on oral as well intravenous supplementation with potassium, bicarbonate, calcium and phosphorus. Simultaneously, as per the modified BFM -90 protocol (four drug based regimen-Prednisolone, vincristine, daunorubicin, cyclophosphamide along with l-asparaginase), he was started on induction protocol. By the end of 3rd week of induction therapy, his urine output started normalizing and finally settled at the end of induction therapy. At present he is in the maintenance phase of chemotherapy.

We report the case of a 16-year-old female patient with a known history of coeliac disease, who presented with the complaints of diarrhea, vomiting and generalized body weakness. On examination, she was found to have dehydration, decreased power in all her limbs, cervical lymphadenopathy and hepatosplenomegaly. Investigations showed severe hypokalemia, hyponatremia, hypomagnesemia, hypoglycemia and mildly enlarged kidneys on ultrasonography. Biopsy of the duodenum confirmed the flare up of coeliac disease, while cervical lymph node biopsy was positive for atypical lymphoid infiltrate and a morphology suggestive of non-Hodgkin's lymphoma. The immune profile performed on this sample confirmed the presence of activated/non-germinal center type of diffuse large B cell lymphoma (DLBCL), which was morphologically aggressive in type. The bone marrow biopsy was hypocellular and was negative for any infiltration. The patient was suspected to have developed infiltration of one or both kidneys leading to a rare presentation of Fanconi's syndrome. She was given first dose of rituximab on the 14th day of her admission. Unfortunately, she developed cardiopulmonary arrest and expired on the next day. We recommend screening for a possible renal involvement in patients with DLBCL and in patients with unusually deranged serum electrolytes as seen in Fanconi's syndrome. Renal biopsy is considered the gold standard modality for diagnosis and if possible, an earlier sample in a patient with newly developed acute kidney injury can save future complications.
