A Solution for the Treatment of a Neglected Subset of Rare Diseases

Grant E Fisher

Article Type: Position Statement | First Published: May 07, 2020

Individual HRDs are made up of small patient populations, thus the high individual prices will amount to a relatively small total cost to insurers and the healthcare system overall. Treatments for HRDs will, in almost all cases, represent the first and only available treatments. As the collective price will not be problematic and with treatments being the first available, insurers will have an incentive to cover the prices necessary to develop and commercialize these therapies....

Non-biopsy Diagnosis of Hereditary Transthyretin Amyloidosis Presented with Cardiomyopathy and Peripheral Neuropathy in a Chinese Man in Hong Kong

Mei Han Ho, MBBS, MRes (Med), MRCP, Pui Lun Yip, MB, ChB, FHKAM (Med), Cheuk Bong Ho, MBBS, MRCP, Felix Chi Kin Wong, MBBS, MHKC (Path), Sammy Pak Lam Chen, FRCPA, FHKAM (Pathology) and Chi Yuen Wong, FHKCP, FHKAM (Med)

Article Type: Case Report | First Published: May 16, 2020

Amyloidosis is a rare disease characterized by deposition of misfolded amyloid protein, which commonly affects myocardium, nerves, kidneys and various organs. The clinical presentation is highly variable. We herein describe, to our knowledge, the first case of a Chinese man with hereditary transthyretin related cardiac amyloidosis (ATTR) with Ala117Ser mutation in Hong Kong who presented with peripheral neuropathy and congestive heart failure. Echocardiography showed left ventricular hypertrophy...

Rare Diseases in Mediaeval Europe

Dooms M

Article Type: Review Article | First Published: March 28, 2020

Monastic rules made an end to infanticide and child neglect in the Middle-Ages by caring for children with (rare) disorders: Disabled and impaired citizens became part of daily life. Historic, paleo-pathological, iconographic and genetic research revealed several cases of acromegaly, achondroplasia, alpha-1-antitrypsin deficiency, cystic fibrosis, Down syndrome, Dupuytren’s contraction, goiter, Marfan syndrome, Paget’s disease and phenylketonuria. These observations want to illustrate that d...

Case Series Synopsis: Gaucher Disease Type 1 Patients Treated with Eliglustat over 6 Years

Cristina Fraga, Sonia Medeiros, Sara Serpa and David Silva

Article Type: Case Series | First Published: January 08, 2020

Gaucher disease (GD) type 1 is a lysosomal storage disorder associated with bone disease, hepatosplenomegaly, anemia and thrombocytopenia. Here we present a case series from 5 (3 females and 2 males) Portuguese individuals from a single institution with GD type 1 who were treated with substrate-reduction therapy (eliglustat, 84 mg once or twice daily) for 6-years. Four cases were switched from IV imiglucerase (28 U/kg q2 week [n = 1]) or 45 U/kg q2 week [n = 3]) and one was enzyme-replacement th...

Disseminated Cryptococcosis in a Deceptively Immunocompetent Adolescent

Vivek Sood, Raja Ramachandran, Rakesh Kumar Pilania, Arun Prabhakar, Neeraj Inamdar, Navin Pattanashetti, Vibhu Joshi, Madhubala Sharma, Amit Rawat, HS Kohli and KL Gupta

Article Type: Case Report | First Published: October 28, 2019

Cryptococcosis particularly if disseminated or extrapulmonary, in an otherwise immune-competent individual, especially if young, requires thorough evaluation for underlying primary immunodeficiency including Mendelian susceptibility to mycobacterial disease (MSMD). In this context, we describe an adolescent diagnosed with disseminated cryptococcosis involving skin, lymph nodes, spleen and hepato-biliary involvement with reduced IL-12β1 receptor expression suggesting underlying MSMD. Following i...

Fulminant Progressive Brainstem Encephalitis as Initial Manifestation of NeuroBechet's Disease

Tierra Rodriguez AM, MD, Fernandez Diaz A, M2, Perez Ruiz D, MD and Lopez Prada B, MD

Article Type: Case Report | First Published: October 07, 2019

Bechet's disease is a multisystemic process that can mimic many other diseases. Neurological features can be its first-onset symptoms. Brainstem is usually affected, so that a wide differential diagnosis is mandatory. We report the case of a patient who developed a fulminant and rapidly progressive brainstem encephalitis owing to NeuroBechet's disease. Bechet's disease (BD) is a hard-to-diagnose entity. Neurological features can sometimes be the first manifestation of the disease. Its symptoms c...

Dietary Intake and Hedonic Preferences for Sodium in Children, Adolescents and Young Adults with Barth Syndrome

Stacey Reynolds PhD, OTR/L, FAOTA, M Emily Tucker MS, OTR/L, W Todd Cade, PT, PhD, Nicol Clayton and Shelly J Lane PhD, OTR/L, FAOTA

Article Type: Original Research | First Published: September 28, 2019

Individuals with Barth syndrome (BTHS) present with decreased activity tolerance and high fatigability. Recent evidence suggests that differences in metabolic function in BTHS negatively impact the production of aerobic energy for activity and maintenance of muscle mass. Recommendations on a metabolically beneficial diet are complicated by selective eating behaviors often seen in individuals with BTHS. While known to be selective eaters with a preference for salty foods, there is limited evidenc...

Evaluation and Valuation of the Price of Expensive Medicinal Products: Application of the Discounted Cash Flow to Orphan Drugs

Mark Nuijten, Hans Joerg Fugel and Jan Vis

Article Type: Research Article | First Published: December 19, 2018

The current policy for price negotiations on high prices of orphan drugs in Europe is neither a transparent nor a structural solution for reimbursement decisions for orphan drugs. In a previous paper, we proposed the Discounted Cash Flow model as an alternative assessment methodology for the price of innovative drugs including the investor's perspective. The objective of this current paper was to apply this concept to orphan drugs in The Netherlands, where pharmaceutical companies were recently ...

Concurrent Breast Cancer and Thymoma in an Immune Reconstituted HIV Positive Patient

SJ Winceslaus, Venkateshwaran Sivaraj, Julia Hall and Ramsay Singer

Article Type: Case Report | First Published: April 21, 2018

The expectation that the introduction of modern cART against HIV, leading to viral suppression and functional cure, would also herald complete immunological recovery has not materialised. In reality, even with the most effective cART, complete immunological recovery is seldom achieved, especially, if initiated at later stages of the disease. Thus, patients who do not achieve full immunological recovery remain at increased risk of cancers, chronic immune activation, inflammation and impaired coag...
