Atypical hemolytic uremic syndrome is a thrombotic microangiopathy that can cause life-threatening anemia, thrombocytopenia, and acute renal failure. When triggered during pregnancy or the acute postpartum period, the disease is referred to as pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS). Women who suffer P-aHUS may later want to consider future pregnancy. These patients are at high, though not well-estimated, risk of relapse. Eculizumab, a monoclonal antibody against complement 5 (C5), has been highly successful in treating acute attacks of P-aHUS, but little is known about the effectiveness of eculizumab maintenance therapy throughout pregnancy. In this case report, we present a woman whose first pregnancy was complicated by severe P-aHUS. In her next pregnancy, she was maintained on eculizumab. She delivered a healthy infant at term and had no recurrences of P-aHUS during the pregnancy or in the postpartum period.
Viral meningitis, also known as aseptic meningitis, is the most common cause of meningitis and is responsible for between 26,000 and 42,000 hospitalizations yearly in the United States. Bacterial meningitis affects about 4,000 people each year, while viral meningitis affects about 10 people in every 100,000. The most commonly identified pathogens are enterovirus, herpes simplex virus and human immunodeficiency virus. Varicella, rabies and influenza are other viruses that are rarely responsible for viral meningitis. Varicella Zoster is a relatively common disorder in immunocompromised patients characterized by radicular pain and grouped vesicular eruptions. The typical findings in reported cases of VZV meningitis involve skin manifestations and classical signs of meningitis such as neck stiffness. However, only a few cases of meningitis caused by Varicella Zoster Virus (VZV) have been reported. The incidence of VZV meningitis in immunocompetent patients has been reported to be as low as 0.5%. We report an atypical presentation of VZV meningitis in an immunocompetent patient with headache, dizziness, sequalae of seizures without fever and skin manifestations. Our patient is a 59‐year‐ old African American male who presented with worsening dizziness, confusion, ataxia, lethargy and left‐sided frontal headache. Magnetic resonance imaging revealed mild to moderate burden of white matter abnormality, nonspecific but most likely due to chronic microvascular ischemic disease. No acute stroke. The next day sedation was weaned off and patient remained seizure free on continuous EEG and was extubated 3 days later the CSF came back positive for an elevated Varicella PCR of 42016. Patient was seen by infectious diseases consultant and was advised a course of acyclovir 10mg/kg intravenous every 8 hours for 14 days. All other antibiotics were stopped. Upon discharge, the patient had fully recovered from his symptoms with no neurologic sequalae. This unique case illustrates an atypical presentation of VZV meningoencephalitis in an immunocompetent patient that lacks many of the obvious features that usually distinguish the disease. Our patient lacked the vesicular rash, as well as other typical features of aseptic meningitis including nuchal rigidity, headache, photophobia, etc. Additionally, the patient's course was complicated by seizure, another relatively uncommon feature of VZV meningoencephalitis. VZV infection or reactivation is, rightfully, most commonly associated with the vesicular rash and prodromal pain that usually accompanies it.
