Guideline for oral healthcare of adults with Huntington’s disease

What we don't need to prove but need to do in multidisciplinary treatment and care in Huntington's disease: a position paper

BACKGROUND

Huntington's disease is a complex neurodegenerative hereditary disease with symptoms in all domains of a person's functioning. It begins after a healthy start in life and leads through the relentless progression over many years to complete care dependency and finally death. To date, the disease is incurable. The long progressive complex nature of the disease demands multiple disciplines for treatment and care of patient and family. These health care providers need inter- and multidisciplinary collaboration to persevere and be efficacious in this devastating disease trajectory.

DISCUSSION

The position paper outlines current knowledge and experience alongside the experience and consensus of a recognised group of HD multidisciplinary experts. Additionally the patient's voice is clear and calls for health care providers with a holistic view on patient and family. Building long-term trust is a cornerstone of the network around the patient. This paper describes a managed care network comprising all the needed professionals and services. In the health care system, the role of a central coordinator or case manager is of key importance but lacks an appropriate guideline. Other disciplines currently without guidelines are general practitioners, nurses, psychologists, and social workers. Guidelines for neurologists, psychiatrists, geneticists, occupational therapists, speech and language therapists, physiotherapists, dieticians, and dentists are being discussed. Apart from all these profession-specific guidelines, distinctive inter- and multidisciplinary collaboration requirements must be met.

CONCLUSIONS AND RECOMMENDATIONS

The complex nature of Huntington's disease demands multidisciplinary treatment and care endorsed by international regulations and the lay association. Available guidelines as reviewed in this paper should be used, made available by a central body, and updated every 3-5 years. Time needs to be invested in developing missing guidelines but the lack of this 'proof' should not prevent the 'doing' of good care.

The impact of 0.2% chlorhexidine gel on oral health and the incidence of pneumonia amongst adults with profound complex neurodisability

AIMS

Investigate the effect of toothbrushing with 0.2% chlorhexidine gel on oral health and pneumonia amongst patients with a neurodisability who are fed via percutaneous endoscopic gastrostomy.

METHOD

Forty-nine patients at the Royal Hospital for Neuro-disability were recruited to an observational study. Daily toothbrushing with 0.2% chlorhexidine gel was undertaken for 12 months by trained nursing staff. Plaque and gingival health were assessed every six weeks using the Simplified Debris Index and the Basic Periodontal Examination. The annual incidence and prevalence of episodes of pneumonia experienced by patients whilst using the chlorhexidine gel were compared to rates from the previous year.

RESULTS

Plaque levels and the proportion of patients with periodontal pocketing > 3.5 mm significantly reduced, P < .001, with chlorhexidine toothbrushing. Total number of pneumonia episodes (75-67), antibiotics administered (73-64), and radiographs taken (19 to 16) were lower in the year wherein chlorhexidine was employed, and hospitalisations dropped by 31% (16-11), but these reductions were not statistically significant. No adverse events were reported.

CONCLUSION

Daily toothbrushing with 0.2% chlorhexidine undertaken by a trained and supported nursing staff was effective in improving oral health but did not significantly affect annual rates of pneumonia amongst patients.

International Guidelines for the Treatment of Huntington's Disease

The European Huntington's Disease Network (EHDN) commissioned an international task force to provide global evidence-based recommendations for everyday clinical practice for treatment of Huntington's disease (HD). The objectives of such guidelines are to standardize pharmacological, surgical and non-pharmacological treatment regimen and improve care and quality of life of patients. A formalized consensus method, adapted from the French Health Authority recommendations was used. First, national committees (French and English Experts) reviewed all studies published between 1965 and 2015 included dealing with HD symptoms classified in motor, cognitive, psychiatric, and somatic categories. Quality grades were attributed to these studies based on levels of scientific evidence. Provisional recommendations were formulated based on the strength and the accumulation of scientific evidence available. When evidence was not available, recommendations were framed based on professional agreement. A European Steering committee supervised the writing of the final recommendations through a consensus process involving two rounds of online questionnaire completion with international multidisciplinary HD health professionals. Patients' associations were invited to review the guidelines including the HD symptoms. Two hundred and nineteen statements were retained in the final guidelines. We suggest to use this adapted method associating evidence base-medicine and expert consensus to other rare diseases.

Update on Huntington's disease: advances in care and emerging therapeutic options

INTRODUCTION

Huntington's disease (HD) is the most common hereditary neurodegenerative disorder. Despite the fact that both the gene and the mutation causing this monogenetic disorder were identified more than 20 years ago, disease-modifying therapies for HD have not yet been established.

REVIEW

While intense preclinical research and large cohort studies in HD have laid foundations for tangible improvements in understanding HD and caring for HD patients, identifying targets for therapeutic interventions and developing novel therapeutic modalities (new chemical entities and advanced therapies using DNA and RNA molecules as therapeutic agents) continues to be an ongoing process. The authors review recent achievements in HD research and focus on approaches towards disease-modifying therapies, ranging from huntingtin-lowering strategies to improving huntingtin clearance that may be promoted by posttranslational HTT modifications.

CONCLUSION

The nature and number of upcoming clinical studies/trials in HD is a reason for hope for HD patients and their families.
