A case of minimal change disease during pregnancy - benefits of early diagnosis and use of corticosteroids.

Nephrotic syndrome presenting in pregnancy is rare and poses a diagnostic and therapeutic challenge. Timing of renal biopsy is important given the increased risk of bleeding and miscarriage, and the choice of immunosuppression is limited due to the teratogenicity profiles of standard drugs. We report and discuss a case of minimal change disease diagnosed by renal biopsy during early pregnancy and treated with corticosteroids throughout the pregnancy. Prompt diagnosis and treatment of glomerular disease in pregnancy are vital to prevent poor maternal and fetal outcomes.

Post-partum catastrophic antiphospholipid syndrome presenting with shock and digital ischaemia - A diagnostic and management challenge.

Catastrophic antiphospholipid syndrome is a rare multisystem autoimmune condition characterised by rapid development of widespread thrombotic disease and subsequent multi-organ failure. It is the most severe complication of antiphospholipid syndrome, carrying significant morbidity and mortality. We report a patient with post-partum catastrophic antiphospholipid syndrome with cardiac, hepatic, renal and cutaneous manifestations. The diagnostic challenges in establishing a definitive diagnosis in catastrophic antiphospholipid syndrome is discussed, along with the difficulties in managing these patients in the intensive care unit.

A novel nucleotide oligomerisation domain 2 mutation in a family with Blau syndrome: Phenotype and function.

Mutations in the nucleotide binding domain of the PRR, NOD2, are associated with the autoinflammatory diseases Blau syndrome and early-onset sarcoidosis. Current theories suggest that constitutive activation of the NOD2 pathway may be responsible for pathogenesis of these diseases. Here, we report the phenotype of a kindred with Blau syndrome caused by a novel NOD2 mutation (p.E383D). Signaling protein and cytokine expression were examined, and the results of these experiments challenge current theories of constitutive NOD2 activation in the pathophysiology of Blau syndrome.

Novel complement factor H gene mutation causing atypical haemolytic uraemic syndrome: early Eculizumab prevents acute dialysis.

We describe the clinical course and response to treatment of atypical haemolytic uraemic syndrome (aHUS) in two sisters presenting to our hospital 6 years apart with a novel complement factor H mutation that has not been described previously in literature and demonstrates the genetic complexity of this ultra-rare disease. The contrast in course and outcome of disease between the two sisters highlights the rapid evolution of management of aHUS, the importance of rapidly establishing a diagnosis, and how minimizing time to eculizumab therapy significantly reduces associated morbidity and mortality.
