과수면 증후군의 Clarithromycin 기전
각성에 대한 항생제 매개 개선: 수면과다 증후군에서 Clarithromycin의 작용 기전
연구 개요
상세 설명
과도한 주간 졸음과 긴 수면 시간은 근긴장 이영양증, 파킨슨병, 중추신경계 과다수면 증후군을 포함한 많은 신경학적 장애의 공통적인 특징입니다. 이러한 후자의 증후군은 임상적 표현형이 겹치는 장애 그룹이며, 하이포크레틴 결핍으로 인한 기면증(기면증 유형 1)의 경우를 제외하고 잠재적으로 병태생리학을 공유합니다.
이러한 장애에서 병리학적 주간 졸음은 직업 수행 능력을 손상시키고 삶의 질을 제한하며 자동차 및 기타 사고 위험을 두 배 이상 증가시킵니다. 이러한 수면과다증 증후군의 대부분의 근본적인 원인은 알려져 있지 않기 때문에 치료는 각성 촉진과 관련된 모노아민성 신호를 증가시키는 것을 목표로 합니다. 그러나 수면과다증 환자의 최소 4분의 1은 이러한 치료로 만족스러운 증상 조절을 달성할 수 없으며 종종 장애 또는 병가가 필요합니다. 현재 치료 표준의 이러한 실패를 해결하기 위해 과도한 주간 졸음에 대한 새로운 치료법이 분명히 필요합니다.
이전 연구에서 클래리스로마이신은 졸음의 중증도, 일상 생활의 확장된 활동에서 졸음과 관련된 제한 및 졸음과 관련된 삶의 질에서 임상적으로 유의미하고 의미 있는 개선을 가져왔습니다. 기능 장애에 기여하는 과다수면 장애의 부수적인 증상인 긴 수면 시간과 수면 관성도 클래리스로마이신으로 개선되었습니다.
가설: Clarithromycin은 자가 보고 및 객관적 테스트로 측정한 바와 같이 과도한 졸음 및 기타 수면과다 장애 증상을 감소시킬 것입니다.
목표 1: 중추 과다수면 증후군 환자에서 각성을 촉진하고 졸음을 감소시키는 클래리스로마이신의 중추 신경계 매개체를 확인합니다.
가설 1a: 체외에서 감마-아미노부티르산-A(GABA-A) 수용체 기능의 뇌척수액(CSF) 향상의 변화는 자가 보고 및 객관적으로 측정된 졸음의 개선과 연관될 것입니다.
가설 1b: 기능적 연결성의 변화는 자가 보고 및 객관적으로 측정된 졸음의 개선과 관련될 것입니다.
목표 2: 클라리스로마이신이 중추성 수면과다 증후군 환자에서 전신 염증의 변화 및 위장관 미생물 구성의 변화를 포함하여 졸음을 감소시킬 수 있는 신경 외 메커니즘을 조사합니다.
가설 2a: 클래리트로마이신 사용으로 졸음 개선은 전신 염증 감소, 특히 종양 괴사 인자-알파(TNFα) 수치 감소와 양의 관계가 있을 것입니다.
가설 2b: clarithromycin 사용으로 인한 졸음의 개선은 위장 장세균불균형의 조절과 양의 상관관계가 있을 것입니다.

Change in Epworth Sleepiness Scale (ESS) Score
기간: Day -1, Day 14
|
The Epworth Sleepiness Scale asks participants to respond to 8 scenarios with how likely they are to fall asleep on a 4-point scale where 0 = "would never doze" and 3 = "high chance of dozing".
Total scores range from 0 to 24 where higher scores indicate a higher chance of falling asleep during daytime activities.
The change in ESS score is obtained by subtracting the total score at Day 14 from the baseline score.
Scores above 0 mean that the mean score at Day 14 was lower than the mean score at Baseline, indicating less sleepiness.

Change in Maintenance of Wakefulness Test (MWT) for Sleep Latency
기간: Day -1, Day 14
|
The MWT polysomnographic procedure for sleep latency examines how well participants stay awake during several trials where participants relax in a quiet room for 40 minutes.
One study found the mean sleep latency among persons without a sleep disorder to be 35.2
minutes.
The change from baseline is calculated as baseline sleep latency minus sleep latency at Day 14, in minutes.
Positive values result when the duration of sleep latency at Day 14 is lower than at Baseline.

Change in Gamma-aminobutyric Acid Receptor A (GABA-A) Potentiation
기간: Day -1, Day 14
|
Cerebrospinal fluid (CSF) is drawn to determine the change in levels of GABA-A potentiation between the study arms.
The difference between measured current with GABA alone and the current measured with GABA + CSF yields a measure of potentiation for each CSF sample in each condition.
The change from baseline is calculated as the baseline value minus the value at Day 14.
|
Day -1, Day 14
|
|
Change in Default Mode Network (DMN) Connectivity
기간: Day -2, Day 13
|
The default mode network (DMN) consists of a group of highly correlated brain regions most active during quiet rest, while the task positive network (TPN) is the brain network activated for goal-directed tasks.
DMN connectivity changes with sleep states and it is increasingly implicated in the symptomatology of sleepiness.
During resting state, sleep deprived participants demonstrate reduced static connectivity with the DMN.
Changes in DMN between the Baseline 1 (Day - 2) and Day 13 visits are compared between treatment groups, particularly using quasi-periodic patterns (QPPs), which interrogate network-level connectivity on a dynamic scale.
Preservation of the temporal dimension provides more insight into how this spatiotemporal network propagates across condition and pathology.
The DMN/TPN QPP correlation is reported.

Day -2, Day 13
|
|
Change in Tumor Necrosis Factor - Alpha (TNF-α)
기간: Day -1, Day 14
|

|
Change in Gastrointestinal Microbiome Composition
기간: Day -1, Day 14
|
Changes in microbiome composition, as measured by alpha diversity using the Shannon Index, via 16S ribosomal ribonucleic acid (rRNA) sequencing results are compared between study arms.
The Shannon Index measures both abundance and evenness of microbial species, values of 0 indicate that a community has only one species.
The higher the value the higher the diversity of species in a particular community.
Change from baseline is calculated by subtracting the Day 14 value from the value at Baseline.
Numbers greater than 0 indicate that the Day 14 Shannon index value is lower than at Baseline.

Change in Fatigue Severity Scale (FSS) Score
기간: Day -1, Day 14

Fatigue severity is measured with the Fatigue Severity Scale (FSS).
The FSS is a 9-item instrument where responses are on a scale of 1 to 7 where 1 = "disagree" and 7 = "agree".
Total scores range from 9 to 63 where higher scores indicate greater fatigue.
The change in FSS score is obtained by subtracting the total score at Day 14 from the Baseline score.
Scores above 0 signify that the mean score at Day 14 was lower than the mean score at Baseline, indicating decreased fatigue.

Positively phrased items are reverse scored so that the total score ranges from 20 to 100 where higher scores indicate greater severity of fatigue.
The change in MFI-20 score is obtained by subtracting the total score at Day 14 from the Baseline score.
Scores above 0 signify that the mean score at Day 14 was lower than the mean score at Baseline, indicating decreased fatigue.

Two additional questions relate to how much time it takes for the respondent to wake up in the morning.
Total scores range from 21 to 105 and higher scores indicate increased difficulty from tiredness.
The change in SIQ score is obtained by subtracting the total score at Day 14 from the baseline score.
Scores above 0 signify that the mean score at Day 14 was lower than the mean score at Baseline, indicating reduced difficulty awakening.

Change in Functional Outcomes of Sleep Questionnaire (FOSQ) Score
기간: Day -1, Day 14
|
The FOSQ is a 30-item instrument assessing how sleepiness impacts daily activities.
There are five subscales assessing General Productivity, Activity Level, Vigilance, Social Outcomes, and Intimate and Sexual Relationships.
Items are scored on a 4-point scale where 1 = extreme difficulty and 4 = no difficulty.
Subscale scores are obtained by calculating the mean score for the items in that subscale and each can range from 1 to 4, where higher scores indicate less difficulty due to sleepiness.
A total score is obtained by calculating the means of the subscale scores and multiplying that by the number of subscales with a score.
The total score ranges from 5 to 20 and higher scores indicate less difficulty from sleepiness.
The change in FOSQ score is obtained by subtracting the total score at Day 14 from the Baseline score.
Scores below 0 signify that the mean score at Day 14 was higher than the mean score at Baseline, indicating reduced difficulty from sleepiness.

Change in MRI Functional Connectivity
기간: Day -2, Day 13
|
For functional connectivity analyses, each functional scan is parceled into the 246 regions of interest (ROIs), spanning Yeo's 7 networks contained in the Brainnetome Atlas and mean timecourse is calculated for each group.
Pearson correlations between each pair of ROIs are calculated, to determine the strength of functional connectivity between each pair of regions and inter/intra-network.
This yields a functional connectivity matrix for each functional scan (at both a subject- and group-level).
These correlation matrices are Fischer z-transformed and averaged across each condition to create a mean functional connectivity matrix for each condition.
Here, the average default mode network (DMN) connectivity is reported.
Z-scores have a mean of 0 and scores higher than 0 indicate increased functional connectivity.
The change from Baseline is calculated by subtracting the Day 13 score from the score at Day -2.
Values lower than 0 mean that the Day 13 score was higher than at baseline.

Change in MRI Task Performance - N-Back Accuracy
기간: Day -2, Day 13

Participants complete a working memory task during functional magnetic resonance imaging (fMRI).
The change in task performance is measured as accuracy during 3 different levels of back tasks (0-back, 1-back, and 2-back), from baseline to on-treatment (Day 13).
The 0-back test has participants respond to a prespecified stimulus and is a control condition.
The 1-back involves remembering and responding to a prior stimulus, while a stimulus two trials earlier is responded to with the 2-back.
The change in the percentage of correct responses is obtained by subtracting the percentage at Day 14 from the Baseline percentage.
Values below 0 signify that the mean percent accuracy at Day 14 was higher than the mean percent accuracy at Baseline, indicating increased accuracy.
