Alport's syndrome and intracranial aneurysm: mere coincidence or undiscovered causal relationship

A 44-year-old Caucasian man with a history of deceased donor renal transplant for end-stage renal disease from Alport's syndrome (AS), presented with a spontaneous subarachnoid haemorrhage and hydrocephalus. Following an external ventricular drain for the hydrocephalus, a CT angiography revealed a dissection of the left vertebral artery extending into vertebro-basilar junction necessitating a bypass between left occipital artery to left posterior inferior cerebellar artery. He had a posterior fossa Craniectomy, C1 laminectomy and coiling off, of the left vertebral artery. Postprocedure course was prolonged but uneventful with complete recovery and normal renal function 18 months postpresentation. AS, a disease caused by abnormalities in the synthesis of type IV collagen, can cause aneurysms with severe and permanent neurological sequalae. We present a case of AS with intracranial arterial dissection with potential life-threatening consequences and discuss the genetic and molecular basis of AS along with review of the relevant literature

Seizures, renal failure and acute respiratory failure: not your typical case of Henoch-Schonlein purpura

A 30-year-old Caucasian woman with no prior medical history presented with pedal oedema, arthralgias and abdominal pain with diarrhoea, following a respiratory infection. She had mild abdominal tenderness along with a purpuric rash on the extremities and was anaemic. Following initial workup for anaemia and rash, her condition deteriorated with renal impairment, respiratory failure and seizures necessitating ventilatory support, dialysis and steroids. Serologies were negative, and skin biopsy showed leucocytoclastic vasculitis without vascular IgA deposition, and renal biopsy showed subendothelial, mesangial deposits of IgA with C3 indicative of Henoch-Schonlein purpura (HSP). She was treated with steroids, haemodialysis and on 6-month follow-up recovered renal function. We present the case to illustrate that HSP, though rare in adults, can present with multiorgan failure, with renal, pulmonary and central nervous system involvement, and the need for early diagnosis and prompt treatment for rapid clinical recovery

Methamphetamine (N-methylamphetamine)-induced renal disease: underevaluated cause of end-stage renal disease (ESRD)

A 26-year-old Caucasian man with no medical history, except years of oral and intravenous drug abuse, presented with fatigue, shortness of breath, epistaxis and uncontrolled hypertension. He was pale with skin ecchymosis over his thighs and was anaemic, with severe renal failure and metabolic acidosis. Following initial clinical stabilisation of the patient, a renal biopsy was obtained, which showed vascular and glomerular changes consistent with thrombotic microangiopathic injury and advanced glomerulosclerosis. He was treated with antihypertensives and required haemodialysis. He admitted using ‘crystal meth’ regularly for many years, which is likely responsible for his renal failure. We present the case to illustrate methamphetamine-induced renal disease leading to end-stage renal disease and to bring awareness among practising clinicians, ancillary healthcare workers and public health professionals of this often undervalued cause of renal failure, which can be prevented
