Study Description

Brief summary:

2528/5000 Historically the city of Guarapari / ES is known as the city health by the popular therapeutic effect of its sands in diverse diseases. The articular diseases are among the list of the aggravations that popularly the monazitic sands exert some therapeutic effect, emphasizing. Rheumatic diseases include osteoarthritis of the knee. It is a disease with a high prevalence and in recent years have presented an increase in the incidence supposedly caused by the aging population and due to the epidemic of obesity. Osteoarthrosis is proven to be a disease that leads to the incapacity and restriction of the individual's ability to come and go with high monetary costs for the patient and the government. In view of these facts presented, the objective is to investigate the therapeutic potential of monazite sands in elderly patients submitted to serial, controlled and standardized exposure, compared to patients exposed to beach sand without radiation.

  • Condition or Disease:Osteo Arthritis Knee
  • Intervention/Treatment: Radiation: Natural gamma radiation from the monazite sands
    Radiation: Normal sands exposure patients
  • Phase: N/A
Detailed Description

A sample of 150 patients with primary knee osteoarthrosis will be selected for the study, divided into two random groups that will be exposed to sand (one monazite sand group and another beach sand group without radiation) for 12 months. The groups will be evaluated at time 0 (at the patient's arrival in the group) and at 1, 2, 3, 6, 9 and 12 months of exposure following the literature criteria for evaluation of knee osteoarthrosis (Visual Analogue Scale (EVA) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)) and non-specific and specific biomarkers (C-reactive protein, erythrocyte sedimentation rate, IL-1β, IL-6, IL-8, TGF-β, and TNF-α). In addition, the groups will undergo an initial interview and monitoring of the pharmacological therapies used prior to the study and during the months of follow-up using the Dáder methodology of pharmaceutical care adapted to the study. As a result, the scientific evidence of the efficacy of monazitic sands in knee osteoarthrosis is expected not only by clinical criteria but also by laboratory evidence on the markers of the inflammatory and degenerative process that allow us to document the real value of the monazitic sands for health of the population, to establish a great line of research for the state of Espírito Santo and to value the State of Espírito Santo and the municipality of Guarapari as potential itineraries for SPA tourism (aiming to improve health).

Study Design
  • Study Type: Interventional
  • Estimated Enrollment: 150 participants
  • Allocation: Randomized
  • Intervention Model: Parallel Assignment
  • Intervention Model Description: The study will be carried out on the beaches of Areia Preta de Guarapari (source of monazitic sands) and on the beach of Itapoã in Vila Velha (sand without radiation). Selected patients will have their knees fully covered with beach sand, properly analyzed for radioactivity and temperature, for 30 minutes on 2 mornings a week for a period of 1 (one) year.
  • Masking: Single (Outcomes Assessor)
  • Primary Purpose: Health Services Research
  • Official Title: Effect of Monazite Sands in Patients With Osteoarthritis of the Knee
  • Actual Study Start Date: May 2019
  • Estimated Primary Completion Date: December 2019
  • Estimated Study Completion Date: August 2020
Arms and interventions
Arm Intervention/treatment
Experimental: Natural gamma radiation from the monazite sands
Patients selected for the study will have their knee (s) affected by osteoarthrose fully submerged in the monazite beach sand 2 (two) times per week for 30 (thirty) minutes each session at the same location and at the same time of day. The natural gamma radiation doses of the monazite sands will be monitored, the radiation measurements gamma will be associated with the atmospheric and climatic measurements of each group. It is understood here as atmospheric measurements, level of solar radiation, spectrum of sunlight at the time of exposure, humidity, wind speed, ultraviolet radiation level, amount of ions present in the air and measurements of the magnetic field in the place.
Radiation: Natural gamma radiation from the monazite sands
Patients selected for the study will have their knee (s) affected by osteoarthrose fully submerged in the monazite beach sand 2 (two) times per week for 30 (thirty) minutes each session at the same location and at the same time of day.
Placebo Comparator: Normal sands exposure patients
Patients selected for the study will have their knee (s) affected by osteoarthrose fully submerged in the no-monazite beach sand 2 (two) times per week for 30 (thirty) minutes each session at the same location and at the same time of day. To ensure the absence of radiation, mesuaraments of possible radiation will be monitored.
Radiation: Normal sands exposure patients
Patients selected for the study will have their knee (s) affected by osteoarthrose fully submerged in the no-monazite beach sand 2 (two) times per week for 30 (thirty) minutes each session at the same location and at the same time of day.
Outcome Measures
  • Primary Outcome Measures: 1. Change in the Visual analgesic scale (0-10) [ Time Frame: 1, 3, 6, 8 and 12 months ]
    Change pain perception through the visual analgesic scale of the volunteers. It consists of a graduated scale of 0 to 10 with regular intervals where zero means absence of pain and 10 is the maximum pain already experienced by the patient.
  • Secondary Outcome Measures: 1. Change total score (0 - 96) the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)- (lower scores indicate lower levels of symptoms or physical disability) [ Time Frame: 1, 3, 6, 8 and 12 months ]
    Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire comprises three subscale. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function.
  • 2. Change the number of patient with higher concentration of Nonspecific inflammatory markers [ Time Frame: 1, 3, 6, 8 and 12 months ]
    Quantification of nonspecific inflammatory markers (HSV and CRP) and specific (IL-1β, IL-6, IL-8, IL-17, TNF-α and TGF-β) per patient
  • 3. Change the frequency of Self-medicatition to treat pain [ Time Frame: 1, 3, 6, 8 and 12 months ]
    Evaluation of the frequency of self-medication before and during the intervention
