1/4. Effects of cyclosporine A in hyperzincaemia and hypercalprotectinaemia.INTRODUCTION: Hyperzincaemia and hypercalprotectinaemia with systemic inflammation, recurrent infections, hepatosplenomegaly, arthritis, anemia, cutaneous inflammation, and failure to thrive is an extremely rare disease and no therapy is reported. AIM: To evaluated the effects of cyclosporine A in hyperzincaemia and hypercalprotectinaemia in terms of serum cytokine level changes before and after treatment. methods: A 10-year-old girl was admitted suffering from pyoderma gangrenosum, hepatosplenomegaly, anemia that was unresponsive to iron supplementation, persistent inflammation, arthritis, and increased serum zinc. The level of serum calprotectin was extremely high; therefore, we diagnosed hyperzincaemia and hypercalprotectinaemia and started cyclosporine A treatment. Twelve cytokines in serum were measured before and one year after treatment. RESULTS: cyclosporine A was very effective. Her skin lesion and joint pain were alleviated and quality of life was markedly improved. c-reactive protein had decreased and anemia had improved. While zinc levels had fallen, calprotectin remained at an extremely high level. Of the cytokines examined, interleukin -6 serum levels had fallen and interleukin -8 showed a marked reduction after treatment. CONCLUSION: cyclosporine A is effective for hyperzincaemia and hypercalprotectinaemia. serum interleukin -8 may be useful in assessing the therapeutic effects of cyclosporine A in hyperzincaemia and hypercalprotectinaemia.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
2/4. Identification of the carrier of the Bedlington Terrier copper disease.copper (Cu) was assayed in serial liver biopsy specimens of 5 pups resulting from a mating of 2 Bedlington Terrier carriers of inherited Cu toxicosis; the latter were sibling offspring of an affected Bedlington Terrier and a normal dog. Between 5 and 7 months of age, 1 of the pups had acceptable hepatic Cu values in each of 6 specimens. The hepatic concentration of Cu in another pup increased steadily from 801 to 3,874 micrograms/g dry weight. The other 3 pups may be heterozygotes (carriers); in 1--the hepatic Cu peaked at 1,043 micrograms/g at 9 months, in the 2nd--at 636 micrograms/g at 7 months, and in the 3rd--at 492 micrograms/g at 7 months. Acceptable concentrations were present in these 3 dogs at 9 to 14 months. Results in the present study indicate that heterozygotes may have 1 normal and 1 abnormal controller gene for regulating their hepatic Cu metabolism, thus accounting for the increased hepatic Cu concentration only in the early months of life. The affected Bedlington Terrier with 2 abnormal genes was unable to suppress the progressive hepatic accumulation of Cu. Paired liver biopsy specimens obtained at 5 to 7 months and at 14 or 15 months of are might distinguish the heterozygote from the normal and the affected Bedlington Terrier pups.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
3/4. An X-linked disease of the nervous system with disordered copper metabolism and features differing from Menkes disease.We studied 2 of 4 affected boys with a new disease associated with abnormalities of copper metabolism. The four cases occurred in two generations of a family. This syndrome was similar to Menkes disease in some respects: X-linked recessive inheritance, marked psychomotor retardation with seizures, low serum copper and ceruloplasmin levels, and a block in gut copper absorption. There were also striking differences from Menkes disease. patients had normal birthweight at term, no hypothermia, and survived beyond the usual Menkes age group with static neurologic disease including hypotonia and choreoathetosis. In addition, general examination of both children was unremarkable apart from undescended testes and growth retardation. The hair, facies, and skin were normal and there was no radiologic evidence of bony changes. Detailed studies of copper absorption were performed.- - - - - - - - - - ranking = 52.002708116545keywords = family (Clic here for more details about this article) |
4/4. The congenital "magnesium-losing kidney". Report of two patients.A 39-year-old man with a lifelong history of tetany and hypocalcaemia was found to have hypomagnesaemia (0.29 mmol/l) due to renal magnesium loss. His asymptomatic 29-year-old brother had a similar disorder. Both were infertile and had severe oligospermia but normal endocrine function. They had medullary nephrocalcinosis and glomerular filtration rate was reduced. Renal biopsy showed patchy interstitial fibrosis and some glomerular sclerosis. Electron microscopy showed thickened basement membranes in damaged glomeruli and in tubules in areas of fibrosis. Tests of renal tubule function were normal. Hypocalcaemia and tetany were corrected by oral magnesium supplements which raised the serum magnesium level to around 0.54 mmol/l.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
