Renal infarction due to lupus vasculopathy.

In the ISN/RPS 2003 classification of lupus nephritis (LN) renal vascular lesions are not mentioned. We present a patient with postpartum lupus vasculopathy. The renal biopsy in our patient showed concentric intimal thickening with narrowed lumen. No inflammatory changes were found. It also revealed immunoglobulin and complement deposition on the wall of the arteriole. These changes indicate lupus vasculopathy. The glomeruli revealed diffuse proliferative glomerulonephritis, with wire loops and cellular crescent in one glomerulus. The patient showed improvement with immunosuppression.

Management of Guillain-Barré syndrome with plasmapheresis or immunoglobulin: our experience from a tertiary care institute in South India.

Guillain-Barré syndrome (GBS), an acute inflammatory demyelinating polyneuropathy is the most common generalized paralytic disorder. The objective was to study the outcome of disability grade in two groups of GBS treated with plasmapheresis alone and treated with IVIg alone. A retrospective analysis of all consecutive patients with GBS, admitted in our intensive care unit during the period of 3 years, 2009-2012 were included in the study. All patients of GBS who were to be treated with plasmapheresis or IVIg, the modality of management were always decided at their preference and consent after explaining the modalities to patient/family. The plasma exchange done was ∼200-250 mL of plasma per kilogram weight in five sessions (40-50 mL/kg per session) within 7-14 days. The replacement fluid contained 100 mL of 20% albumin diluted in 1000 mL of normal saline and 1000 mL of fresh frozen plasma. IVIg was administered as 0.4 g/kg body weight daily for 5 days. Our observations brought out the following, both the plasmapheresis and IVIg treatments were effective in reducing the disability grade amongst all time points, i.e., at presentation, immediate post-therapy and after 4 weeks. There was a marginal superiority in plasmapheresis over IVIg effect. However, whether the delay in presentation as noted in our study probably would have contributed to this effect was conjectural.
