Clinical Trial Summary

the study is intended to test the effect of Nigella sativa nasal oil drops on selected outcomes among patients with chronic rhinosinusitis using prospective clinical trial design. To achieve the aim of the current trial the following research hypotheses are postulated: H1. The total severity of symptoms mean scores of patients with CRS who will use Nigella sativa nasal oil drops will be different from the total severity of symptoms mean scores of a control group. H2. The total sleep quality mean scores of patients with CRS who will use Nigella sativa nasal oil drops will be different from the total sleep quality mean scores of a control group. H3. The total patient satisfaction mean scores of patients with CRS who will use Nigella sativa nasal oil drops will be different from the total patient satisfaction mean scores of a control group.


Description:

The clinical trial will be conducted to examine the effect of administering a daily dose of 100 mg Nigella sativa nasal oil drops for four weeks on selected outcomes which include severity of symptoms, sleep quality and patient satisfaction among patients with chronic rhinosinusitis. The trial will be conducted on 102 adult patients with chronic rhinosinusitis who will be randomly assigned to either a study group (51 participant) who will receive Nigella sativa beside the standard treatment or a control group (51 participant) who will receive the standard treatment only. The current trial will be conducted in the Ear, Nose and Throat (ENT) outpatient clinic at Kasr Al Ainy University Hospital, Cairo, Egypt. Required data will be collected by using the following four tools: (a) Demographic and Medical Data Form (DMDF), (b) Sino-Nasal Outcome Test 22 (SNOT-22), (c) Sleep Quality Scale (SQS) and (d) Treatment Satisfaction Questionnaire for Medication (TSQM). The researcher prepared a flyer that will be handed in for the study group to explain how the oil will be utilized by the participants. The formal initial approval was obtained from Research Ethics Committee at Faculty of Nursing, Cairo University and an official permission was also obtained from the hospital administrators for conducting the trial. The researcher collaborated with Emeritus Professor in Pharmacognosy from the College of Pharmacy for the preparation of N. sativa nasal oil drops from Nigella sativa and Sesame seeds. Thereafter, data collection will be carried out from both groups using the following five steps as follows: recruitment and randomization; interviewing; initial assessment; intervention; follow-up and monitoring.

Intervention

Other:
Nigella sativa nasal oil drops
in addition to the standard treatment, the study group will receive one nasal drop of the prepared N. sativa nasal oil drops in each nostril twice daily which are equivalent to a daily dose of 100 milligram of a pure N. sativa oil for four weeks. N. sativa oil was prepared from N. sativa seeds and it was mixed in Sesame oil with a ratio of 1 to 1. The prepared drops will then be placed in dark containers with a specific dropper. Each participant will be instructed regarding the dose, proper position and steps, assisted by a flyer which will be developed by the researcher.
Drug:
standard treatment
intranasal corticosteroids in addition to nasal irrigation with sea water; for patients with allergy the standard treatment is oral antihistamines with or without oral corticosteroids.

Outcome

Type Measure Description Time frame Safety issue
Primary Severity of physiological symptoms as measured by Sino-Nasal Outcome Test 22 (SNOT-22) SNOT-22 consists of 22 items that measure four domains as follows: (a) nasal symptoms domain that contains eight items, (b) otologic symptoms domain which includes four items, (c) sleep symptoms domain which includes seven items and (d) emotional symptoms domain that contains three items. SNOT-22 is scored using a Likert scale where 0="No problem", 1="Very mild problem", 2="Mild or slight problem", 3="Moderate problem", 4="Severe problem" and 5="Problem as bad as it can be". The overall scores of the SNOT-22 is ranged from 0 to 110 with higher scores suggesting symptom severity. from two to four weeks
Primary Sleep quality as measured by Sleep Quality Scale (SQS) Sleep Quality Scale (SQS) consists of 28 items, which evaluate six domains of sleep quality as follows: (a) daytime dysfunction/symptoms which contain twelve items, (b) restoration after sleep which include four items, (c) difficulty falling asleep that contain four items, (d) difficulty getting up that include three items, (e) difficulty in maintaining asleep which contain two items and (f) satisfaction with sleep which include three items. Sleep Quality Scale is scored through a four-point, Likert-type scale; (0 = "few," 1 = "sometimes," 2 = "often," and 3 = "almost always"). Scores on items belong to factors 2 and 5 (restoration after sleep and satisfaction with sleep) are reversely scored. Total scores are ranged from 0 to 84, with higher scores denoting more acute sleep problems. from two to four weeks
Secondary severity of sleep and emotional symptoms as measured by Sino-Nasal Outcome Test 22 (SNOT-22) (sleep and emotional symptoms domains) SNOT-22 consists of 22 items that measure four domains as follows: (a) nasal symptoms domain that contains eight items, (b) otologic symptoms domain which includes four items, (c) sleep symptoms domain which includes seven items and (d) emotional symptoms domain that contains three items. SNOT-22 is scored using a Likert scale where 0="No problem", 1="Very mild problem", 2="Mild or slight problem", 3="Moderate problem", 4="Severe problem" and 5="Problem as bad as it can be". The overall scores of the SNOT-22 is ranged from 0 to 110 with higher scores suggesting symptom severity. from two to eight weeks
Secondary patient satisfaction as measured by Treatment Satisfaction Questionnaire with Medications (TSQM) Treatment Satisfaction Questionnaire for Medication includes 14 items that assess four key dimensions of treatment satisfaction: (a) effectiveness which includes three items, (b) side Effects which contain five items, (c) convenience that include three items and (d) global Satisfaction that contain three items. Item of TAQM are scaled on 5 or 7 point Likert scale, except one item which is answered with 1= "Yes" or 0= "No". Scores for each domain are calculated independently by adding the TSQM items in each domain and then transforming the composite score into a value ranging from 0 to 100; higher values indicate higher satisfaction, better perceived effectiveness, lower burden associated to side-effects, better convenience. from two to eight weeks
