Rehabilitation Program in Patients With Acromegaly

Impact of a Physical Rehabilitation Program on the Quality of Life of Patients With Acromegaly: a Non-randomized Clinical Trial.

Peripheral muscle strength and fatigue strength will be evaluated using an EMG -810 surface electromyograph and a DIN_TRO traction dynamometer. For the strength test, the muscle evaluated will be the femoral quadriceps, the patient will be instructed to perform the knee extension, with the highest possible isometric force. Your positioning will be seated with your hands crossed over the chest, with the upright trunk adjusted by the backrest in order to allow the angle of 90 ° for hip flexion. For analysis of fatigue strength, surface electromyography of the medial vastus muscle (VM) of the dominant lower limb will be used through the 8-channel surface electromyograph from the gross signal. The endurance test consists of a contraction sustained for 60 seconds using 50% of the highest MIVM obtained in the strength test.

For the execution of the TC6M, the patient will be previously oriented to use sneakers and comfortable clothing. Later it will be positioned in a corridor of 30 meters, demarcated every 3 meters and oriented to walk as fast as possible, but without running, for a total period of 6 minutes. Peripheral saturation of O2 (SpO2), heart rate (HR), modified Borg scale, blood pressure (BP) during the test will be checked. There will be two tests with a 30 minute interval between them. The distance selected will be the patient's best performance. This is based on reducing the learning effect. Subsequently, the data found will be associated with the forecast of Britto et al. (2013) according to age, height and body weight of each individual.

The Acromegaly Quality of Life Questionnaire (AcroQol) is a specific, simple and valid instrument for assessing quality of life in people suffering from acromegaly aged 18-70 years. It can be used in two different fields: in clinical trials of new drugs as well as in the follow-up of patients in clinical practice. This is particularly useful in evaluating the effects of intervention or treatment. The questionnaire is one-dimensional and contains 22 items divided into two scales: one that evaluates physical aspects (eight items) and another that evaluates the psychological aspects (14 items). The latter is also divided into two sub-scales: one evaluates physical appearance and another evaluates the impact of the disease on the patient's personal relationships (seven items each). The score is given from 1 to 5 where, the lower the score, the worse the quality of life.

The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale was developed for individuals with chronic diseases to evaluate health-related quality of life, treating fatigue as a multidimensional concept. This scale has been applied in different groups of patients with different types of dysfunctions. FACIT-F is a specific scale of evaluation of fatigue that has good representation of the individual's frame, considered as an instrument of easy application, and its use authorized by the author of the same. It will be answered by the researcher himself, with 13 questions ranging from 0 to 4, where the higher the score, the less fatigue. Your score goes from 0 to 52.

The Lower Extremity Functional Scale (LEFS) is a self-administered questionnaire for orthopedic assessment of lower limb integrity. It was developed according to the concepts of functionality and disability of the World Health Organization (WHO). This scale comprises 20 questions and each has a score that varies between the minimum of zero (extremely difficult) and the maximum of four points (without difficulty). The sum of all items can generate a maximum total of 80 points. Such a level of punctuation suggests a normal functional state, that is, the higher the value obtained, the higher the level of functionality of the individual. The LEFS scale is easy to apply and can be used at different levels of functionality and disability related to the lower limbs. It is usually used in initial evaluations, during treatment and thereafter, in order to establish new therapeutic goals for patients.

Body weight and height of patients will be measured using a Filizola® mechanical scale with a maximum capacity of 150 kilograms and a sensitivity of 100 grams and a stadiometer. Body mass index (BMI) will be calculated by dividing body mass by height squared.

Evaluates the perception of the degree of effort, performed during the exercise. Currently, it is used in the modified form described with a score varying with scores between 0 where the level of perception of dyspnea (fatigue) or muscle fatigue is "none" until 10 where the level of perception of dyspnea (fatigue) or muscle fatigue is " maximum".

After a physical therapy evaluation, the patient underwent a booklet-guided physical exercise program that lasted two months (3 times per week with a duration of 60 minutes per session). Activities included overall stretching and strengthening (flexion, extension, adduction and abduction movements) and muscular endurance exercises (exercises involving open and closed kinetic chains), along with aerobic conditioning using a functional circuit. The patient was evaluated at 3 different timepoints (baseline, after 8 weeks of training, and after a 4-week washout period with no treatment); thus, he served as his own control. The physiotherapist contacted the patient by phone weekly to follow the progression of the treatment. Throughout the application of the protocol, the patient regularly maintained his follow-up visits with the multidisciplinary team. Moreover, there was no change in pharmacological treatment throughout this period.

Subjects are randomized to have the second bone biopsy done 1,2, or 4 years after the start of PTH.

Cohort 1 was treated with HPTH therapy on original protocol. Cohort 1 participants who consented to the new protocol and were treated with HPTH on the new protocol were followed for safety outcomes only. The Safety population of Cohort 1 consisted of 7 participants.

Cohort 1 (HPTH on Old Study) and Received HPTH on New Study

Cohort 2 consists of participants previously treated with conventional care (CC) throughout the original protocol. Cohort 2 participants who received at least one dose of HPTH on the new protocol were included in safety population. Cohort 2 safety population includes 5 participants.

Cohort 2 (CC on Old Study) and Treated With HPTH on New Study

Cohort 3 consists of new participants (i.e. not previously enrolled) that consented to the revised protocol. The Cohort 3 safety population includes 19 subjects who received any HPTH on the new study.

Participants (in Cohorts 2 and 3) were randomized to receive their second bone biopsy at year 1, 2, or 4 after the start of HPTH therapy. For Cohort 2, the baseline bone biopsy was completed at the start of CC on the original protocol. For Cohort 3, the baseline biopsy was completed immediately prior to the first HPTH dose. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced due to the early termination of the study, so the 2-, and 4-year biopsies were collapsed into one biopsy year group. Cn.BV/TV is one of 8 primary endpoints measured from the bone biopsy. The changes in Cn.BV/TV outcome between two time-points are being reported. The unit of measure is a z-score. Z-scores are normed to standard populations to a mean of zero and a standard deviation of 1. The normal range for a z-score is from -2 to 2. Values above or below this normal range are considered worse outcomes.

Cohort 2 consists of participants previously treated with conventional care (CC) throughout the original protocol. Cohort 3 consisted of all new participants. Efficacy outcomes were only analyzed for Cohorts 2 and 3. (Cohort 1 consisted of previously enrolled participants who were on HPTH therapy on the original protocol and continued on HPTH on the new study as a separate group. These participants were not randomized to a bone biopsy year, nor did they have additional biopsies performed. Cohort 1 participants were followed for safety outcomes only. )

Following their baseline bone biopsy, 5, 5, and 2 participants were randomized to receive their second bone biopsy at years 1, 2, and 4 after the start of HPTH therapy, respectively. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced in size due to withdrawal and the early termination of the study, the 2-, and 4-year biopsies were collapsed into one biopsy year group. Cn.MS/BS is measured from the bone biopsy. This measure demonstrates the percentage of the cancellous bone surface that is actively forming bone. The region of interest is the predefined area of total bone that is being measured. The changes in Cn.MS/BS between two time-points are being reported.

For Cohort 2, the baseline bone biopsy was completed at the start of CC on the original protocol. For Cohort 3, the baseline biopsy was completed immediately prior to the first HPTH dose. Because the sample sizes for the 1-, 2- and 4-year biopsies are reduced due to the early termination of the study, the 2-, and 4-year biopsies were collapsed into one biopsy year group. Ec.OS/BS is measured from the bone biopsy. This measures the rate mineral is being laid down per day on the inner cortical (endocortical) surface in a predefined region of cortical bone. The changes in Ec.OS/BS between two time-points are being reported. The n's in the outcome measure table refer to the number of complete records (non-missing baseline and post-baseline measures).

The 8 primary bone biopsy measures were to be adjusted HPTH dose by fitting the primary bone biopsy model with both linear and quadratic dose covariates added to the model. However, the study was terminated early resulting in only 5, 5, and 2 participants having their biopsies at 1, 2, and 4 years respectively. To add additional linear and quadratic dose covariates to the statistical model with an already small sample sizes would highly risk over-parameterizing the model. Thus no new analysis was performed.
