Neuromyelitis optica spectrum disorder with active replication of hepatitis B virus and seropositive anti-aquaporin-4 antibody: A case report

RATIONALE

Neuromyelitis optica spectrum disorder (NMOSD) associated with active replication of hepatitis B virus (HBV) is rare. High-dose corticosteroids are the mainstay treatment of NMOSD; however, these may cause reactivation of viral replication in patients with stable HBV which may lead to liver damage. Therefore, care should be placed in corticosteroid use in patients with NMOSD and HBV infection.

PATIENT CONCERNS

Herein, we report the case of a 31-year-old woman with NMOSD and HBV infection who was seropositive for anti-aquaporin-4 antibody. The stable and HBV carrier status of the patient led to the deferment of antiviral and hepatoprotective agents in early treatment. However, liver function impairment was detected during follow-up, with an improvement in the best-corrected visual acuity.

DIAGNOSES

The patient was diagnosed with NMOSD with active replication of HBV and seropositive anti-aquaporin-4 antibody considering the medical history and ancillary examinations.

INTERVENTIONS

To manage NMOSD, intravenous high-dose methylprednisolone (20 mg/kg d) was administered for 5 days which was gradually tapered to oral steroids. However, liver function impairment was observed during follow-up; therefore, anti-HBV drugs (entecavir) and hepatoprotective drugs (bicyclol or polyunsaturated phosphatidylcholine) were administered.

OUTCOMES

A marked improvement was observed in the patient's best-corrected visual acuity after 4 weeks of treatment. However, follow-up examinations revealed liver function damage which necessitated administration of antiviral and hepatoprotective drugs. Liver function normalized after 1 month.

LESSON

This case underscores the importance of preventive treatment of liver protection in patients with HBV infection prior to or simultaneous with glucocorticoid therapy and furthermore, there is an urgent need to develop authoritative guidelines regulating corticosteroid use in the treatment of patients with HBV infection.

Bilateral Optic Neuropathy Revealing Chronic Hepatitis B Infection: A Report of A Rare Case

Hepatitis B virus (HBV) infection is a major public health problem. Liver diseases such as cirrhosis and hepatocellular carcinoma are the main causes of mortality and morbidity associated with this viral infection. Ocular manifestations may also arise during the course of HBV infection. We herein present a 44-year-old male with bilateral optic neuropathy revealing chronic HBV infection.

Metabolic and Non-Metabolic Peripheral Neuropathy: Is there a Place for Therapeutic Apheresis?

As the rate of obesity and the incidence of diabetes mellitus have been increasing, diabetic neuropathy has become the most common cause of peripheral neuropathy in developed countries. In addition, a variety of pathogenetically heterogeneous disorders can lead to impairment of the peripheral nervous system including amyloidosis, vitamin deficiencies, uremia and lipid disorders, alcohol abuse, autoimmune and infectious diseases as well as exposure to environmental toxins. We have noted that a combination of these disorders may aggravate the manifestations of peripheral diabetic neuropathy, an effect, which is most pronounced when metabolic and non-metabolic pathologies lead to cumulative damage. Current treatment options are limited and generally have unsatisfactory results in most patients. Therapeutic apheresis (INUSpherese®) allows the removal of metabolic, inflammatory, immunologic and environmental contributors to the disease process and may be an effective treatment option. We reviewed the developments in therapeutic apheresis for metabolic and non-metabolic peripheral neuropathy, including the current literature as well as data from our university diabetes center.
