Resolution of Cholea Movement Secondary to Non-Wilsonian Hepatolenticular Degeneration (NWHD) Post Orthotopic Liver Transplantation (OLT) [Meeting Abstract]

Zivari, K; Tan, P; Kilaru, S; Park, J
Introduction: Non-Wilsonian hepatolenticular degeneration (NWHD) is a heterogeneous neurological disorder occurring secondary to chronic acquired liver disease. Genetically determined familial NWHD is rare, poorly understood, and often mistaken for Wilson's disease (WD). We present a case of a 65-year-old woman with a family history of NWHD, found to have dystonia, parkinsonism, tremor, cerebellar ataxia, progression of behavioral abnormalities who presented with cognitive decline and progression of liver failure. The patient was evaluated for and later underwent Orthotopic liver transplant (OLT) Case Description/Methods: 65-year-old woman with family history of early-onset cirrhosis with dystonia and dyskinesia in her father, sister, and daughter is transferred to our institution after she was noted to have accelerated progression of her neurological decline which started the year prior. The patient was not obese (BMI 27) and did not use any alcohol. Huntington's disease workup was negative. Workup for causes of cirrhosis did not yield any findings including multiple 24-hour urine copper collections, and no finding of Kayser Fleischer rings on ophthalmology exam. Multiple CT and MRI brain showed linear abnormal signal foci noted along a medial portion of the bilateral lentiform nucleus in anterior to posterior orientation. The patient was diagnosed with NWHD and underwent OLT. Pathology on explanted native liver showed focal steatohepatitis, Mallory-Denk bodies, and focal mixed inflammatory infiltrates. The copper stain was negative. Post liver transplant our patient's dystonia, parkinsonism, tremor, cerebellar ataxia, and behavioral abnormalities all resolved.
Discussion(s): Degeneration of basal ganglia leads to movement neurological disorders. There is an association between basal ganglia-related neurological disorders and cirrhosis of the liver in the absence of acquired liver disease such as Wilson's disease. NWHD is a distinct disease entity. Specific areas of the brain, such as the basal ganglia, are more likely to be injured from liver failure. The basal ganglia is involved in control of movement. If damage to this area is not from copper, this condition is the "non-Wilsonian" type. Non-Wilsonian hepatolenticular degeneration may represent a disorder of other poorly known toxic depositions. We demonstrate that with liver transplantation this damage can be reversible

Onabotulinum Toxin A Injections Into the Salivary Glands for Spinal Muscle Atrophy Type I: A Prospective Case Series of 4 Patients

OBJECTIVE:The aim of the study was to investigate the safety and efficacy of onabotulinum toxin A injection to the salivary glands under ultrasound guidance for the treatment of sialorrhea in patients with spinal muscular atrophy type I. DESIGN:Prospective case series with four patients with spinal muscular atrophy type I who received onabotulinum toxin A injection to parotid and submandibular glands for sialorrhea as part of clinical care. All four patients received validated surveys for measuring drooling, including objective measures of number of bib changes, and number of mouth wipes before injection and 4-6 wks after injection. Research was limited to survey completion. Scales included the Drooling Severity and Frequency Scale and the Drooling Impact Scale as well as a new scale used in our clinic, the Posterior Drooling Scales looking at coughing/choking and number of aspiration pneumonias. RESULTS:There were no adverse events. All four patients showed clinically significant improvements. The improvement in drooling using the Drooling Impact Scale was statistically significant (paired t test, t = 3.243, P = 0.048). All patients improved with number of mouth wipes. CONCLUSION:Ultrasound-guided onabotulinum toxin A injections to the salivary glands may be a safe and effective method of decreasing drooling in patients with spinal muscular atrophy type I.
