Efeito da estimulação elétrica percutânea do campo nervoso no controle dos sintomas/atividade do sistema nervoso em pacientes com diabetes tipo 1 ou 2 (PENFS)
Efeito da estimulação elétrica percutânea do campo nervoso (PENFS) no controle dos sintomas e na atividade do sistema nervoso autônomo em pacientes com diabetes mellitus
The purpose of this study is to evaluate whether stimulation of the vagus nerve can improve nausea and vomiting in diabetic gastroparetic patients.

Descrição detalhada
The vagus nerve is one of the main determinants of gastrointestinal motility and gastric emptying. It has been speculated that neuropathy of the vagus nerve is the cause of the delay in gastric emptying in gastroparesis, the symptoms of which include nausea, vomiting, weight loss, early satiety, abdominal pain and bloating.
Percutaneous Electrical Nerve Field Stimulation (PENFS) has been approved by the FDA to treat adolescents with functional abdominal pain associated with irritable bowel syndrome. In this study, the impact of PENFS on gastroparesis symptoms will be evaluated.
After informed consent is obtained, participant eligibility will be assessed at a Screening Visit. A Hemoglobin A1C level (HgbA1c) will be drawn for this purpose. Eligible participants will then return for 5 Study Visits at which, they will:
- Complete will complete 4 questionnaires
- Lie in a supine position and have ECG electrodes applied to the chest and/or arms, palmar skin electrodes placed on the fingers of the non-dominant hand to measure galvanic skin response (GSR) and sympathetic nerve activity, and a chest strap to record respiratory activity. Once the equipment is placed, electrocardiogram (ECG) and GSR will be recorded for 20 minutes in the supine position. After the 20 minutes, participants will be asked to sit while ECG and GSR are recorded for 2 additional minutes. Participants will then stand for an additional 2 minutes of ECG and GSR recordings.
- Have a PENFS device applied to the left ear (the device will be applied at the first four study visits, and not at the fifth). The device will remain in place for 5 days after each visit.
Each participant will have a PENFS device applied at the study visits, however, participants are randomized to whether they will receive active stimulation during the study. The device will remain in place for 5 days after each visit. On the morning of Day 6 after each study visit, the participants will remove the PENFS device and return it at the next study visit.
Participants will also complete a daily diary to document symptoms over the previous 24 hours. Prior to each study visit, participants will be asked to refrain from caffeine on the day of the visit and to refrain from nicotine use for 24 hours prior to the visit.

Intervenção / Tratamento |
|---|---|
|
Comparador Ativo: ACTIVE (electrical charge)
The PENFS device is placed behind the patient's left ear and connected to stimulation needles on the auricle. The appliance transmits low-frequency electrical impulses throughout the auricle. |
The IB-Stim is a percutaneous electrical nerve field stimulator (PENFS) system intended to be used in patients 11-18 years of age with functional abdominal pain associated with irritable bowel syndrome (IBS). The IB-Stim is intended to be used for 120 hours per week up to 3 consecutive weeks, through application to branches of Cranial Nerves V, VII, IX and X, and the occipital nerves identified by transillumination, as an aid in the reduction of pain when combined with other therapies for IBS.

Descrição da medida |
Prazo |
|---|---|---|
|
Change in Gastroparesis Cardinal Symptom Index Daily Dairy
Prazo: Baseline, Week 5
|
A modified version of the GASTROPARESIS CARDINAL SYMPTOM INDEX - DAILY DIARY (GCSI-DD) will be used. The questionnaire evaluates 4 gastroparesis symptoms (nausea, early satiety, postprandial fullness, upper abdominal pain) and asks participants to rate the severity of symptoms over the past 24 hours on a scale from 0 (none) to 4 (very severe). Additionally, vomiting episodes are reported (0 for none, 1 for one episode, 2 for two episodes, 3 for three episodes, or 4 for four or more episodes). Lower total scores indicate fewer or less severe symptoms. |
Baseline, Week 5
|
|
Change in Patient Assessment of Upper Gastrointestinal Disorder Symptoms
Prazo: Baseline, Week 5
|
Scores are calculated by averaging the scores for each item in the subscale, with scores ranging from 0 (none or absent) to 5 (very severe). Optimal outcome would be a score of zero, no episodes/symptoms. |
