Henoch–Schönlein purpura in adults

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.

An exceptional cause of hemoptysis in the elderly patient : IgA vasculitis

We describe here the case of a 73-year-old woman who presented a recurrent macular rash, acute respiratory distress, and hemoptysis. Chest CT scan showed diffuse ground-glass opacities that were suggestive of alveolar hemorrhage. With the development of severe acute kidney injury and nephrotic-range proteinuria (creatininemia 2.6 from 1.9 mg/dL with overt proteinuria 34 from 2.1 g/g creat), a kidney-lung syndrome was evoked. Skin biopsy revealed leukocytoclastic vasculitis with IgA deposits. Blood tests showed an increased IgA level. Those findings were consistent with a rare form of IgA vasculitis (formerly Henoch-Schönlein syndrome), the originality of the case lying in the occurrence of a kidney-lung syndrome in an elderly patient.

[Management of mesenteric ischemia in the era of intestinal stroke centers: The gut and lifesaving strategy]

Mesenteric ischemia is a gut and life-threatening, medical and surgical, digestive and vascular emergency. Mesenteric ischemia is the result of an arterial or venous occlusion, a vasospasm secondary to low-flow states in intensive care patients, aortic clamping during vascular surgery or intestinal transplantation. Progression towards mesenteric infarction and its complications is unpredictable and correlates with high rates of mortality or a high risk of short bowel syndrome in case of survival. Thus, mesenteric ischemia should be diagnosed and treated at an early stage, when gut injury is still reversible. Diagnostic workup lacks sensitive and specific clinical and biological marker. Consequently, diagnosis and effective therapy can be achieved by a high clinical suspicion and a specific multimodal management: the gut and lifesaving strategy. Based on the model of ischemic stroke centers, the need for a multidisciplinary and expert 24/24 emergency care has led, in 2016, to the inauguration of the first Intestinal Stroke Center (Structure d'urgences vasculaires intestinales [SURVI]) in France. This review highlights the pathophysiological features of chronic and acute mesenteric ischemia, as well as the diagnosis workup and the therapeutic management developed in this Intestinal Stroke Center.
