[Steroid-Dependent Nephrotic Syndrome Due to Minimal Change Glomerulonephritis Treated with Rituximab].

47-year-old woman suffering from minimal lesion glomerulonephritis previously undergone high-dose steroid therapy and subjected to exacerbations of nephrotic syndrome after therapy discontinuation. It was decided to initiate off-label treatment with Rituximab at a dosage of 375 mg/m2 administred at zero-time, one-month and three months with good therapeutic response and resolution of the clinical laboratory picture. The therapy was well tolerated and had no side effects. This scheme could be an alternative to the conventional therapeutic scheme with steroids or other classes of immunosuppressive drugs, especially in order to avoid problems related to prolonged exposure to steroid therapy.

[Extra-hepatic manifestations associated with Hepatitis and virus infection].

Hepatitis E virus (HEV) is a significant public health problem that affects almost 20 million individuals annually and cause acute liver injury in 3,5 million. Hepatitis E virus can cause acute, fulminant and chronic hepatitis and has been associated with a range of extrahepatic manifestation. The spectrum of these manifestation is still emerging. Acute pancreatitis and neurological, renal, hematologic, and muscoloskeletal manifestations have been described. Renal injury include membranoproliferative glomerulonephritis with or without cryoglobulinemia, membranous glomerulonephritis and tubular necrosis. The etiopathogenesis of extrahepatic manifestation is only supposed. It could be caused by a direct tossic effect of HEV or by an autoimmune process. We report a case of a 46 years old man who presented with acute hepatitis E. He was diagnosed to have acute severe renal failure and severe pancreatitis due to hepatitis E. Few cases have been reported in the literature concerning patients suffering from hepatitis E and severe extraepatic manifestations with a benign course and complete recovery.

[Therapy of glucocorticoid induced osteoporosis]. / Terapia dell'osteoporosi da glucocorticoidi.

Glucocorticoid-induced osteoporosis (GIO) is a major cause of secondary osteoporosis that starts early after the beginning of therapy even for low drug doses. Glucocorticoids are used for the treatment of immunologic nephropathies and in the setting of kidney transplant. In clinical practice, a number of algorithms are available; they allow us to estimate the long-term risk of major osteoporotic fracture; but none of them is specific for GIO. To date, the therapeutic approach comprises both general measures aimed at correcting calcium and vitamin D intake, and drugs (bisphosphonates, teriparatide, hormone replacement therapy, denosumab) that ameliorate bone mineral density and patient outcomes.
