A group of 50 patients (26 men and 24 women, mean age 50 +/- 19 years and range 21 to 67) on chronic hemodialysis (HD) and with basal levels of hemoglobin (Hb) less than or equal to 8 g/dl was treated with recombinant human erythropoietin (r-HuEpo) during 3 months. r-HuEpo was started at 50 U/kg I.V. 3 times a week, immediately after each session of HD, for 4 weeks, and this dose was increased in steps of 25 U/kg until a Hb level of 12 g/dl or a maximum dose of 100 U/kg were reached. Complete blood counts and biochemical profile were performed before the first dose of r-HuEpo and once weekly and monthly respectively during the period of treatment. In 8 patients the red-cell life span was studied with cromium 51 labelled erythrocytes just before and after treatment. One patient had a grand mal seizure and the r-HuEpo was discontinued. In 44 patients the mean hematocrit increased from 21.8% to 32.1% and in the other 5 there were no response because of iron deficiency. There were no changes in leucocytes and platelets counts and consistent decreases in iron and ferritin serum concentrations were observed despite oral supplementation of iron. In the 8 patients studied the shortened erythrocyte survival did not suffer any significant variation with r-HuEpo. Predialysis creatinine, urea and phosphorus blood levels increased significantly at 3th month of treatment but there was no increase in potassium. In 32.6% of previously normotensive and hypertensive patients an increase in blood pressure was founded. Thrombosis of arteriovenous fistulas and other severe clinical side effects were not observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Eclampsia is a hypertensive disorder of pregnancy that is defined by the new onset of grand mal seizures on the basis of preeclampsia and a leading cause of maternal and fetal mortality worldwide. Presently, magnesium sulfate (MgSO4) is the most effective treatment, but the mechanism by which MgSO4 prevents eclampsia has yet to be fully elucidated. We previously showed that systemic inflammation decreases the seizure threshold in a rat eclampsia-like model, and MgSO4 treatment can decrease systemic inflammation. Here, we hypothesized that MgSO4 plays a neuroprotective role in eclampsia by reducing neuroinflammation and brain edema. Pregnant Sprague-Dawley rats were given an intraperitoneal injection of pentylenetetrazol following a tail vein injection of lipopolysaccharide to establish the eclampsia-like seizure model. Seizure activity was assessed by behavioral testing. Neuronal loss in the hippocampal CA1 region (CA1) was detected by Nissl staining. Cerebrospinal fluid levels of S100-B and ferritin, indicators of neuroinflammation, were detected by enzyme-linked immunosorbent assay, and ionized calcium binder adapter molecule 1 (Iba-1, a marker for microglia) and glial fibrillary acid protein (GFAP, a marker for astrocytes) expression in the CA1 area was determined by immunofluorescence staining. Brain edema was measured. Our results revealed that MgSO4 effectively attenuated seizure severity and CA1 neuronal loss. In addition, MgSO4 significantly reduced cerebrospinal fluid levels of S100-B and ferritin, Iba-1 and GFAP activation in the CA1 area, and brain edema. Our results indicate that MgSO4 plays a neuroprotective role against eclampsia-like seizure by reducing neuroinflammation and brain edema.

Atypical hemolytic uremic syndrome (aHUS) is a rare form of thrombotic microangiopathy (TMA) which generally presents as a triad of thrombocytopenia, hemolytic anemia and renal failure. We present the case of a 69-year-old woman with ongoing fevers, arthralgias, diffuse rash and pharyngitis for 3 months. Investigation revealed an elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and ferritin; however, autoimmune and infectious studies were unremarkable, raising the suspicion for adult onset Still's disease (AOSD). Before out patient therapy could be initiated, she presented to our emergency room (ER) with a grand mal seizure and persistence of her initial triad of fevers, arthralgias and rash. Evaluation revealed non-immune hemolytic anemia, thrombocytopenia, and abnormal renal function consistent with TMA and the patient was subsequently started on plasmapheresis, hemodialysis and corticosteroid therapy. ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs)-13 activity was 38%, ruling out thrombotic thrombocytopenic purpura (TTP). A kidney biopsy demonstrated glomerular changes of TMA and a diagnosis of secondary aHUS triggered by AOSD was established. The patient was treated with eculizumab and high dose steroids with improvement in her laboratory values, eventually becoming hemodialysis-independent. This case highlights the clinical urgency in the prompt recognition of AOSD, a potent inflammatory disorder, which when co-existing with a complement- dysregulatory defect, can significantly augment TMA disease severity.
