This case shows that percutaneous transluminal angioplasty for an arteriovenous fistula may induce subclavian steal syndrome, and a modified graft inclusion technique was useful in improving the high flow of an arteriovenous fistula.
To examine the efficacy of long-term administration of lanthanum carbonate, changes in serum Ca, phosphate, whole parathyroid hormone (wPTH), and ALP were examined in 40 patients who were able to tolerate dosage of lanthanum carbonate over a continuous period of 24 months. Concurrently, concomitant administration of other phosphate binders, cinacalcet, vitamin D, etc., was also examined. After 24 months, serum phosphorus levels (P levels) had decreased to within management target of guidelines, from 6.16 ± 1.44 mg/dL to 5.58 ± 1.15 mg/dL, and this effect was maintained for 2 years. There were no changes in Ca level. wPTH did not change significantly but tended to increase at 12 months. The dose of concomitantly administered calcium carbonate and sevelamer hydrochloride was reduced. The P-lowering function of lanthanum carbonate still held steady at 24 months following the start of dosage. Because of the rising trend seen in wPTH, dose of cinacalcet and/or vitamin D need to be modulated. Reducing the number of concomitantly administered phosphate binder tablets was desirable from the standpoint of patient adherence.
A 50-year-old woman was transferred to our hospital because of acute renal failure and thrombocytopenia. Due to rapid enlargement of the kidney, we first suspected that she had diffuse renal invasion of anaplastic carcinoma or lymphoma of the kidney. Anti-bacterial treatment for complicated urinary tract infection and hemodialysis treatment resulted in recovery of both renal function and thrombocytopenia. Serial CT study demonstrated disappearance of kidney swelling and multiple masses within the kidney. We finally made a diagnosis of acute multifocal bacterial nephritis. Timely initiation of dialysis therapy and appropriate anti-bacterial treatment was essential to rescue this case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
