[Symptoms of HELLP syndrome due to vitamin B12 deficiency: report of seven cases]. / Pseudo-HELLP syndrome par carence en vitamine B12: à propos de sept cas.

ABSTRACT

INTRODUCTION: HELLP syndrome is characterized by generalised thrombotic microangiopathy predominant in the liver. Many investigators consider HELLP syndrome to be a variant of severe preeclampsia. Several other conditions have similar laboratory findings in common with HELLP syndrome and should be eliminated before pregnancy termination. PATIENTS AND METHODS: The authors report seven observations of patients with biological criteria that mimic HELLP syndrome secondary to severe vitamin B12 deficiency. CONCLUSION: Vitamin B12 or B9 deficiency developed during pregnancy have laboratory findings similar to those of HELLP syndrome.
