Increased Cyclosporine Concentrations in the Absence of Cyclosporine Administration

Increased cyclosporine concentrations in the absence of cyclosporine administration.

A 9-year-old girl was admitted to our hospital with juvenile metachromatic leukodystrophy (arylsulfatase A deficiency). Symptoms of this lysosomal storage disease, such as decreased school performance and compromised motor skills, had started 1 year earlier. She underwent bone marrow transplantation from a matched unrelated donor after receiving conditioning with fludarabine, treosulfan, and th...

Determination of cyclosporine concentrations with monoclonal antibodies.

We measured cyclosporine in whole blood from normal volunteers administered single oral doses of the drug and from two renal-transplant patients on immunosuppressive maintenance therapy, by liquid chromatography (I) and by radioimmunoassay with use of nonspecific polyclonal (II), specific monoclonal (III), and nonspecific monoclonal (IV) antibodies. Concentrations determined by III were equival...

Evaluation of cyclosporine A eye penetration after administration of liposomal or conventional forms in animal model

A lot of researches have investigated the effects of topical cyclosporine A on the eye surface layers’ diseases. By now the main limitation in cyclosporine application is the low permeation of the drug into the posterior segments of the eye. The aim of present study was to formulate high permeable dosage form can be beneficial in the topical treatment of the uveitis. To reach higher corneal dru...

Concomitant administration of cyclosporine and ketoconazole in idiopathic nephrotic syndrome.

BACKGROUND The deliberate use of ketoconazole to reduce the need for cyclosporine (CsA) is not new, but it is particularly relevant because of the high cost of CsA. Many studies have documented this benefit in renal and cardiac transplants, but this co-administration has not been reported in patients with nephrotic syndrome. METHODS This retrospective study included 207 nephrotic patients who...
