acyclovir and Neuromyelitis-Optica

Intractable or persistent hiccups and nausea (IHN) are rarely associated with herpes zoster (HZ-IHN). We aimed to identify the clinical characteristics of HZ-IHN by comparing them with those of neuromyelitis optica spectrum disorder associated with IHN (NMOSD-IHN).. We collected 8 patients with HZ-IHN and 12 patients with NMOSD-IHN diagnosed between 2002 and 2020 from medical databases. Medical records including clinical information, laboratory data on serum anti-aquaporin 4 (AQP4) antibodies, serological or cerebrospinal fluid findings for the varicella zoster virus, medullary MRI findings, and efficacy of intravenous methylprednisolone pulse (IVMP) therapy were analyzed retrospectively.. The age of onset (69 ± 13 years versus 46 ± 17 years, P = 0.003), percentage of men [7/8 patients (88%) versus 3/12 patients (25%), P = 0.020], serum CRP levels (1.41 ± 1.17 mg/dL versus 0.14 ± 0.33 mg/dL, P = 0.018), and frequency of hemi-cranial nerve involvement [6/8 patients (75%) versus 1/12 patients (8%), P = 0.004] were significantly higher in patients with HZ-IHN than in those with NMOSD-IHN. The hypoglossal and vagus nerves were involved in 5/8 patients (63%) with HZ-IHN. Other clinical parameters, excluding anti-AQP4 antibodies, were similar to those of NMOSD-IHN. MRI revealed ipsilateral hemi-dorsal medullar hyper-intense lesions in 5/8 patients (63%) with HZ-IHN. Acyclovir with IVMP therapy was effective for HZ-IHN.. Clinicians should include HZ-IHN in the differential diagnosis for IHN, and promptly administer acyclovir and IVMP therapy. HZ-IHN is frequently accompanied by lower hemi-cranial nerve palsies and ipsilateral hemi-dorsal medullary hyper-intensity on MRI.. The authors confirm that the data supporting the findings of this study are available within the article (Tables 1 and 2), or its supplementary materials (Table S1).

We report an acute myelitis in a 53-year-old woman that occurred in 7 days after the diagnosis of Th5-6 herpes zoster. Clinical examination revealed hyperhidrosis of left side of her face, neck, arm and upper chest. She also had muscle weakness of her left leg and sensory impairment for light touch and temperature in her chest and legs. Spinal cord MRI demonstrated a longitudinal T

We report a case of bilateral acute retinal necrosis (ARN) following an acute optic neuromyelitis (AONM) in an immunodepressed patient (T CD4 lymphocyte count under 50/mm3) suffering from acquired immunodeficiency syndrome (AIDS). Despite the medical treatment the evolution led to blindness by bilateral total retinal detachment. The neuro-ophthalmological features occurred prior to the retinal manifestation, and the acute optic neuromyelitis occurred after a spreading zoster. The varicella-zoster virus (VZV) seemed to be involved because of recurring cutaneous zoster, spreading of this zoster just before the AONM, previous reports showing a link between VZV and AONM, and VZV and ARN. However, our patient had first an AONM responding well to corticosteroid therapy following one month later by an ARN leading to blindness despite the antiviral treatments received as soon as possible. There is a chronical viremia+ in immunodepressed patients with recurring and spreading zoster. The rupture of the hemato-encephalic barrier observed in AONM could facilitate the invasion of the eye by the virus, leading to an ARN. This hypothesis could explain the two complications due to the VZV, the AONM and the ARN, the first one is of dysimmunitary origin and the second one could probably result of a direct viral attack of the retina. This should incite to treat as soon as possible each retrobulbar optic neuritis in patients with AIDS, especially if past history of zoster.
