Rheumatic Heart Disease School Project

Rheumatic Heart Disease

Acute rheumatic Fever (ARF) results from an autoimmune response due to molecular mimicry between the M-protein on the group A β-hemolytic streptococci (GABHS) cell membrane and cardiac myosin, and may lead through recurrent or sustained inflammation to Rheumatic Heart Disease (RHD). RHD remains a major contributor to morbidity and premature death in the working age population in Nepal. Secondary prevention with regular oral or intravenous administration of penicillin continued until early adulthood is recommended to prevent the progression of the development of endocarditis and subsequent valvular dysfunction. Screening for rheumatic heart disease using echocardiography has the potential to detect rheumatic valvular lesions at an earlier, clinically silent stage, as compared to clinical examination alone and might have a beneficial impact on long-term outcome of children with RHD. Schoolchildren aged 5-16 years from several public and private schools from rural and urban areas in Southeastern Nepal will be screened for RHD using portable echocardiography. Three main inter-related objectives will be pursued in three phases of the study: In a first phase using a cross sectional approach, the prevalence of clinical and subclinical RHD will be investigated among a representative sample of schoolchildren from public and private schools in urban and rural areas. In a second phase, using a cohort study approach among those children diagnosed at different stages of RHD, clinical outcomes with regular medical surveillance will be assessed (a), and clinical and social risk factors associated with prognosis of the disease after receiving medical care at various stages of disease at diagnosis will be determined (b). A third phase will integrate the prevalence rates from phase 1 and the clinical outcomes from phase 2 in a mathematical model to assess the impact of screening and RHD treatment on health resource utilization.

A Comparison of Patients Receiving a Unicompartmental Knee Replacement With Robotic Assistance or...

ArthritisOsteoarthritis4 more

A unicompartmental (partial) knee replacement (UKR) is the removal of one part of the knee joint (a condyle), that has become damaged due to osteoarthritis, and replacing it with an artificial implant. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. A UKR is a highly effective, recognised procedure for patients with end-stage osteoarthritis affecting one compartment of the knee joint. The functional outcomes following UKA are at a minimum of equivalence to total knee arthroplasty procedures, with some recent literature demonstrating improved functional patient reported outcome scores. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). These systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery. With both the NAVIO and CORI Surgical Systems there is a reduction in radiation exposure due to them being image-free. At present, there is some evidence available for the long-term outcomes of knee replacement implanted using robotic assistance (i.e. 2-10 years) however this study is designed to look at the early outcomes following UKR. There is no literature to date to show that robotic-assisted UKR is superior to conventional methods, within the early post-operative period (up to 12 months). This study is designed to show that the NAVIO/CORI surgical systems are better than conventional methods for UKR. The hypothesis is that they will be cost-effective, will reduce the time a patient spends in hospital following their surgery, will improve patient satisfaction during the early recovery period and will improve the patient's early post-operative mobility and function.

Combined Pneumococcal Conjugate and Polysaccharide Vaccination in Inflammatory Rheumatic Disease...

Rheumatoid ArthritisSystemic Lupus3 more

The overall objective of this project is to study the influence of modern anti-inflammatory treatments in established inflammatory rheumatic diseases (IRD) on antibody response elicited by pneumococcal vaccination using 13-valent conjugate vaccine in combined schedules with 23-valent polysaccharide vaccine. In addition, the aim is to study the clinical aspects of vaccination regarding: tolerability in immunosuppressed patients with IRD, impact on existing rheumatic disease, possible association with onset of new autoimmune diseases, long-term immunity following pneumococcal vaccination and efficacy in preventing invasive pneumococcal disease. Results from this study are expected to bridge the existing knowledge gap and contribute to body of evidence needed for recommendations and implementation of vaccination program in IRD patients.

Hepatitis A Vaccine Dosing Regimens Among Pediatric Patients on Immunosuppressive Therapy

Autoimmune Rheumatologic Disease

The study is a prospective, single centre, double-blinded randomized controlled trial whose goal is to compare the immune response of a population of immunosuppressed pediatric rheumatology patients on immunosuppressive medications to two different doses of Hepatitis A vaccine. The objectives are (a) to confirm that adolescents, like their adult counterparts, have a reduced immune response to hepatitis A vaccine, and (b) to compare the immunogenicity of two different dosing options of vaccine for this age group after one and two doses. A total of 60 adolescents aged 12 - 15 years with confirmed chronic rheumatologic conditions for which they are being treated with an immunosuppressive therapy will be recruited from the Rheumatology Clinic at Alberta Children's Hospital (ACH). Those found to have no immunity to hepatitis A will be enrolled. Informed, written consent will be obtained from the parent or guardian of subject, with assent obtained from the study subjects. Subjects will be randomly assigned to two doses of either Avaxim Pediatric® or Avaxim ® (adult) vaccine (Sanofi Pasteur Canada), six months apart, with hepatitis A titres done at baseline and one month after each dose. Both formulations are licensed for this age group.

Evaluation of Influenza A/H3N2 Vaccine in Patients With Rheumatologic Diseases

Systemic LupusSjogren's Syndrome

Studies in the literature have shown reduced effectiveness of influenza A (H3N2) virus vaccine (20-40%) when compared to A (H1N1) and influenza B. This reduction in efficacy may partly result of the need to propagate A (H3N2) virus into egg components for the preparation of the vaccine. Other factors that may also contribute to the reduction of efficacy against A (H3N2) viruses include the high level of genetic diversity and the rate of rapid evolution of this particular virus subtype and the modification of the immune response to the vaccine secondary of prior infection or vaccination. Vaccine efficacy studies are required to verify the immunogenicity of the H3N2 influenza vaccine in immunosuppressed patients with rheumatologic disease. In addition, it is relevant to evaluate the safety of the vaccine in this population as well as the possibility of reactivation of the rheumatologic disease itself. The objectives of this study are to evaluate the immunogenicity of the H3N2 component of the inactivated and fragmented influenza vaccine in patients with two systemic autoimmune rheumatic diseases (Systemic Lupus Erythematosus - Adult and Juvenile, Primary Sjögren's Syndrome).

Dutch Version Fear-Avoidance Component Scale (FACS)

Musculoskeletal PainMusculoskeletal Pain Disorder9 more

Chronic musculoskeletal disorders such as low back and neck pain are responsible for an enormous global burden. Fear-avoidance (FA) can be a predictor for the transition from subacute to chronic low back pain. In patients with neck pain, those who were less fearful about harming their neck, had higher pain tolerance, which might have a positive impact on their level of disability. A new scale, the Fear-Avoidance Component Scale (FACS) was developed by Neblett, Mayer, Hartzell, Williams and Gatchel (2015) to assess FA. It consists of an all-encompassing set of constructs that more effectively deals with all critical issues of the FA concept than current scales do. Current scales have been criticized because of following findings: limited construct validity, little evidence on treatment responsiveness, a lack of evidence-based cut-off scores and items being too narrow or too general. The new scale comprehensively assesses all cognitive, emotional and behavioral components related to the updated version of the FA model by combining items of well-known scales in context of the FA model with items on one's perception of victimization and blame related to an injury. A Dutch version of the FACS is currently lacking. Subsequently, the aim of this study is to investigate different psychometric properties of the generated Dutch version in patients with musculoskeletal disorders.

Yellow Fever Vaccine in Patients With Rheumatic Diseases

Systemic LupusRheumatoid Arthritis9 more

According to World Health Organization (WHO), since December 2016, Brazil is showing a significant increase in cases of yellow fever in humans. In view of this, vaccination is suitable for residents and travelers to the risk area. However, for immunosuppressed patients there is a formal recommendation not to vaccinate with live virus vaccine. On the other hand, the safety and efficacy of the vaccine has been demonstrated in patients with HIV, and safety and seroconversion have also been demonstrated in patients with rheumatic disease who were inadvertently revaccinated for yellow fever. Faced with the impossibility of leaving the high-risk area for some patients the vaccination could be released to only those who have low level of immunosuppression as suggested by some recommendations of medical societies. The availability of a fractional vaccine in the State of São Paulo, which has proved its efficacy, opens the possibility of exposure to a lower number of copies of the virus in the first exposure of immunosuppressed patients, allowing, if necessary, a safer revaccination, after 28 days to obtain of a more effective immunogenic response. The objectives of the study are to evaluate the immune response of the immunization with fractional yellow fever vaccine (neutralizing antibodies) in patients with systemic autoimmune rheumatic diseases residing in a high-risk area. Secondarily, evaluate the possible association between immunogenicity and vaccination with: demographic data, clinical and laboratory activity of the disease in patients with chronic rheumatic diseases, evaluate the curve of viremia and report adverse events. Patients and healthy controls will be vaccinated for yellow fever in the Immunization Center of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP). The patients' screening for exclusion and inclusion criteria will be done at the rheumatology outpatient clinic after medical evaluation. For the controls will be the routine screening of the Immunization Center. The vaccination protocol will be a fractional dose of the yellow fever vaccine on day D0 for both groups. Patients will be evaluated on day D0, D5, D10, D30-4 and D365 and controls only on days D0, D10, D30-45 and D365 for aspartate aminotransferase (AST), alanine aminotransferase (ALT), platelets, urea and creatinine, immunoglobulin M (IgM) by immunofluorescence for Yellow Fever, viremia, autoantibodies.
