[Minimal change disease during lithium therapy: case report].

Lithium is a largely used and effective therapy in the treatment of bipolar disorder. Its toxic effects on kidneys are mostly diabetes insipidus, hyperchloremic metabolic acidosis and tubulointerstitial nephritis. Also, a correlation between lithium and minimal change disease has sometimes been described. We report here the case of a patient with severe bipolar disorder on lithium therapy who, without any pre-existing nephropathy, developed nephrotic syndrome and AKI with histopathologic findings pointing to minimal change disease. The patient was treated with symptomatic therapy; the discontinuation of lithium therapy resulted in the remission of AKI and of the nephrotic syndrome, thus suggesting a close relationship between lithium and minimal change disease.

[Minimal Change Relapse During Pregnancy].

The appearance of nephrotic syndrome during pregnancy is considered an exceptional event, whose incidence is around 0.012-0.025% of all pregnancies, and it is even more rare when the cause is represented by minimal lesions glomerulonephritis. In this article we will describe the case of a patient with a histological diagnosis of glomerulonephritis with minimal lesions, tending to frequent relapses. She was in complete remission since 2013 after treatment with cyclosporine. suspended in May 2017. After few weeks she become pregnant, and the pregnancy was regular until the 23rd week. when a recurrence of nephrotic syndrome appears. She was treated with steroids bolus followed by oral steroid, and afterwards gave birth to a live fetus with spontaneous delivery at 37 weeks The few data in the literature confirm that recurrence of glomerulonephritis due to minimal lesions in pregnancy should be treated rapidly with steroids, that can induce rapid remission and protect both the pregnant than the fetus from even serious damage.

[Atypical hemolytic uremic syndrome related to Oxalyplatin Cancer Chemotherapy responsive to Eculizumab]. / Sindrome emolitico uremica atipica secondaria a chemioterapia con Oxaliplatino responsiva a Eculizumab.

We describe the case of a patient with adenocarcinoma of the colon treated with FOLFOX-4 (5-Fluorouracil, Folinic acid, Oxalyplatin), with subsequent appearance of atypical hemolytic uremic syndrome (aHUS). From 1999 to 2009, 13 cases of atypical HUS receiving chemotherapy with oxaliplatin have been described, as well as some sporadic cases. None of these cases has been treated with eculizumab. This is the first report of a patient with aHUS secondary to Oxalyplatin treated with Eculizumab. This treatment induced a complete remission of the syndrome and, later on, it has been discontinued with clinical and laboratory permanent remission. We identified some genetic mutations in this patient that might have a pathogenic role in the determining aHUS when associated with exposure to Oxalyplatin. Oxalyplatin withdrawal and its replacement to Irinotecan allowed the patient to receive first line chemotherapy continuation (FOLFIRI) with the same life expectancy and the same symptoms free period.
