The Role of Human Pluripotent Stem Cells in Amyotrophic Lateral Sclerosis: From Biological Mechanism to Practical Implications
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disorder, characterized by progressive loss of both upper and lower motor neurons, resulting in clinical features such as muscle weakness, paralysis, and ultimately, respiratory failure. Nowadays, there is not effective treatment to reverse the progression of the disease, that leads to death within 3–5 years after the onset. Nevertheless, the induced pluripotent stem cells (iPS) technology could be the answer, providing disease modelling, drug testing, and cell-based therapies for this pathology. The aim of this work was to conduct a literature review of the past 5 years about the role of iPS in ALS, to better define the neurobiological mechanisms involved in the pathogenesis and the potential future therapies. The review also deals with advanced and currently available technologies used to reprogram cell lines and generate human motor neurons in vitro, which represent the source to study the pathological processes, the relationship between phenotype and genotype, the disease progression and the potential therapeutic targets of these group of disorders. Specific treatment options with stem cells involve Advance Gene Editing Technology, neuroprotective agents, and cells or exosomes transplantation, aimed to replace dead or damaged nerve cells. In summary, this review comprehensively addresses the role of human pluripotent stem cells (hPSCs) in motor neuron diseases (MND), with a focus on physiopathology, diagnostic and prognostic implications, specific and potential future treatment options. Understanding the biological mechanisms and practical implications of hPSCs in MND is crucial for advancing therapeutic strategies and improving outcomes for patients affected by these devastating diseases
The accuracy of discharge diagnosis coding for Amyotrophic Lateral Sclerosis in a large teaching hospital
To evaluate the accuracy of hospital discharge data as a source of Amyotrophic Lateral Sclerosis (ALS) cases for epidemiological studies or disease registries, a validation study was performed. All records of patients discharged in 2005 and 2006 with principal or secondary International Classification of Diseases, 9th rev., Clinical Modification (ICD 9 CM) diagnosis code of ALS (335.20), other anterior horn cell disease (335), spinal cord disease (336), hereditary and idiopathic peripheral neuropathy (356), inflammatory and toxic neuropathy (357), myoneural disorders (358), muscular dystrophies and myopathies (359), were selected from the electronic archive of discharge data of the University Hospital of Udine, Friuli Venezia Giulia Region, North East Italy. Corresponding clinical documentation was reviewed to ascertain the presence of El Escorial criteria, the gold standard. Sensitivity of the ICD 9 CM discharge code 335.20 was 93% (95%CI: 82-99%) and decreased to 91% (95%CI: 77-98%) when suspect ALS was excluded. Specificity was 99% (95%CI: 97-99%). The ICD 9 CM discharge code 335.20 can identify a high percentage of hospitalizations of patients truly affected by ALS and of patients with no ALS, among selected neurological diagnostic codes. To ensure complete ALS case ascertainment, prospective population-based registries or epidemiologic studies require active prospective surveillance and use of multiple sources, among them hospital discharge archives can provide accurate information
The diagnostic, therapeutic and assistance pathway for amyotrophic lateral sclerosis in a north-eastern Italian region: satisfaction of patients and their caregivers
In order to evaluate the users’ satisfaction degree for the diagnostic, therapeutic and assistance services for amyotrophic lateral sclerosis (ALS) in the Italian region Friuli-Venezia Giulia (FVG), a self-compiled anonymous multiple-choice questionnaire was administered to ALS patients and their caregivers. The questionnaire explored 41 different issues covering the following areas: (a) access to diagnostic pathway and communication among patients, families and health professionals; (b) quality of disease monitoring and effectiveness of interventions aimed at mitigating ALS symptoms; (c) easiness of access to assistive devices (e.g. wheelchair, ankle-foot-orthosis) and home assistance; (d) patient’ choices sharing and health professionals empathy. The same issues were proposed both to patients and carers, appropriately adapting the questions, during the period between June and December 2019. The answers were categorised according to criticality level. Median with interquartile range of the numeric variables and percentages of the categorical variables and of the answers to questions were calculated. The mean percentage of satisfied users was 72.8%, considering all the areas. Pain treatment and easiness of access to ambulance transport were the most positive aspects (95.7% and 92.5% of satisfied respondents, respectively), while information about possible enrolment in clinical trials and about possible registration to the regional ALS association were the most critical issues (30.9% and 43.4% of satisfied users). Although the satisfaction level of ALS patients and their caregivers for the services provided resulted generally good, there were some areas that have to be improved. For this purpose, enhancement of multidisciplinary collaboration, sharing of points of view from users and different practitioners and rising awareness among healthcare professionals through clinical audits could be useful. Further research is needed to identify a wider range of users’ unexplored unmet needs
