INTRODUCTION Children with steroid resistant nephrotic syndrome usually require treatment with second-line agents and calcineurin inhibitors such as cyclosporine are now recommended as initial therapy. These agents only recently become available in our environment and their impact on care is unknown. We reviewed the short-term treatment outcomes of their use in comparison with previous outcomes...

Intravenous supra-pharmacological doses of corticosteroids are used in various inflammatory and autoimmune conditions because they are cumulatively less toxic than sustained steroid treatment at lower quantitative dosage. Their action is supposed to be mediated through non-genomic actions within the cell. Common indications for use in children include steroid resistant and steroid dependent nep...

There are limited studies on long-term outcomes of childhood onset nephrotic syndrome (NS). A majority of children with NS have steroid-sensitive nephrotic syndrome (SSNS). Steroid-resistant nephrotic syndrome (SRNS) is associated with a high risk of developing end-stage renal disease. Biomarkers and analysis of genetic mutations may provide new information for prognosis in SRNS. Frequently rel...

Idiopathic nephrotic syndrome, characterized by altered permselectivity of the glomerular filter, is a common chronic renal disorder in children. Most patients are steroid sensitive and respond to therapy with remission of proteinuria (steroid sensitive nephrotic syndrome). Revised Guidelines for treatment of these patients were published recently(1). Approximately 10-20% children with nephroti...

Glucocorticoid-resistant mutants isolated form the glucocorticoid-sensitive human leukemic cell line CEM-C7 can be divided into three phenotypes: those with almost no glucocorticoid-binding activity (r-); those whose steroid-receptor complexes are unstable during attempted activation but are stabilized by the presence of sodium molybdate (actl:molybdate-sensitive); and those whose steroid-recep...

Immune thrombocytopenic purpura (ITP) is a hematological disorder characterized by immunologically mediated destruction of platelets and absence of other causes of thrombocytopenia. Treatment is required when the low platelet count entails risk of serious bleeding. Steroid is the first line of management. Acute refractory ITP with very low platelet count is variably treated with high dose stero...

Eosinophilic gastroenteritis is a rare condition of unknown etiology characterized by eosinophilic infiltration of the bowel. Corticosteroids are the mainstay of EG therapy. Although rare, steroid-resistant EG could be a life-threatening condition with tissue destructive evolution. Associations of eosinophilic gastroenteritis with systemic lupus erythematosus have rarely been reported. In this ...

In this brief article, we summarize recent reports about endogenous ouabain (EO), a cardiotonic steroid hormone. This includes analysis of mammalian EO, the discovery of EO isomers, regulation of intracellular signaling by EO, and the roles of EO in hypertension, pregnancy, and heart and kidney diseases. Novel ouabain-resistant mice that elucidate the key roles of α2 Na pumps and their cardioto...
