RESUMO
Various severe acute respiratory syndrome coronavirus 2 vaccines with different platforms have been administered worldwide; however, their effectiveness in critical cases of COVID-19 has remained a concern. In this national cohort study, 24 016 intensive care unit (ICU) coronavirus disease-2019 (COVID-19) admissions were included from January to April 2022. The mortality and length of ICU stay were compared between the vaccinated and unvaccinated patients. A total of 9428 (39.25%) patients were unvaccinated, and 14 588 (60.75%) patients had received at least one dose of the vaccine. Compared with the unvaccinated, the first, second, and third doses of vaccine resulted in 8%, 20%, and 33% lower risk of ICU mortality in the adjusted model, with risk ratio (RR): 0.92, 95% confidence interval (CI): 0.84-1.001, RR: 0.80, 95% CI: 0.77-0.83, and RR: 0.67, 95% CI: 0.64-0.71, respectively. The mean survival time was significantly shorter in the unvaccinated versus the fully vaccinated patients (hazard ratio [HR]: 0.84, 95% CI: 0.80-0.88); p < 0.001). All vaccine platforms successfully decreased the hazard of ICU death compared with the unvaccinated group. The duration of ICU stay was significantly shorter in the fully vaccinated than in unvaccinated group (MD, -0.62, 95% CI: -0.82 to -0.42; p < 0.001). Since COVID-19 vaccination in all doses and platforms has been able to reduce the risk of mortality and length of ICU-stay, universal vaccination is recommended based on vaccine availability.

PURPOSE: Obstructive sleep apnea (OSA) is a common serious sleep disorder. Melatonin-based drugs such as agomelatine may have beneficial effects on patients with sleep disorders. This study aimed to evaluate agomelatine effects on polysomnography parameters in patients with OSA. METHODS: In this randomized, parallel, and single-blind study, seventy patients 18 years of age or older with obstructive sleep apnea who were referred to the sleep clinic were evaluated. The patients were randomly assigned into agomelatine and control groups. Patients in the agomelatine group received 50 mg agomelatine, one hour before sleep, for three consecutive nights prior to the polysomnography test, while the patients in the control group did not receive agomelatine. Sleep test parameters were compared between the two groups. RESULTS: Three parameters in the agomelatine versus control group showed significant differences. They were the median and interquartile range of the total sleep time, 397 [326.5-437.4] vs. 287.5 [184-393.1; p, 0.004] minuets, sleep efficiency percentage, 75.6 [71-87.4] vs. 65.1 [50.8-80.1; p, 0.005] and the wakening percentage, 7.5 [12.01-27.6] vs. 8.8[18.3-49; p, 0.004] agomelatine vs. control group. Other polysomnography parameters revealed no significant differences between the two groups. CONCLUSIONS: Agomelatine administration in patients with OSA may improve total sleep time, sleep efficiency percentage and the percentage of patients' awakening.

BACKGROUND: Coronavirus disease 2019 (COVID-19), an acute, sometimes severe respiratory illness caused by a novel coronavirus has led to a vast pandemic with an astonishing spread rate. Its treatment is unknown, its mortality is significant, and its socioeconomic complications are uncontrollable. Although there is still little known about the pathogenesis of the disease, severe cases of COVID-19 are usually associated with cytokine release syndrome and high serum levels of inflammatory cytokines, which are believed to be a major cause of mortality in these patients. Different pathways cause inflammation and the release of cytokines. One of these pathways is the Bruton tyrosine kinase (BTK) pathway, which is essential for the production of several anti-inflammatory cytokines. Theoretically, the inhibition of BTK signaling can reduce cytokine levels and subsequent anti-inflammatory effects. OBJECTIVE: This review aims to investigate the role of the BTK pathway in the pathogenesis of COVID-19 and the possible effects of its inhibition in the treatment of this disease. METHODS: This narrative review provides information regarding the use of BTK inhibitors in patients with COVID-19 and discusses whether clinicians should consider these medications while managing their patients based on the literature. Data were gathered using the PubMed, Scopus, and Web of Science databases. RESULTS: Some data support the use of BTK inhibitors for treating COVID-19. CONCLUSIONS: It is recommended that patients continue their medications in this class if they develop COVID-19 and were receiving these agents before the disease developed. The use of BTK inhibitors might enable patients to experience less severe immune responses to the COVID-19. Well-designed studies are needed to evaluate the effectiveness of BTKis in the management of COVID-19. (Curr Ther Res Clin Exp. 2022; 82:XXX-XXX) © 2022 Elsevier HS Journals.
RESUMO
Background: COVID-19 is responsible for the latest pandemic. Dipeptidyl peptidase-4 (DPP-4) is one of the cellular receptors of interest for coronavirus. The aim of this study was to assess the roles of DPP-4 inhibitors in prognosis of COVID-19 infection in patients with type 2 diabetes mellitus. Materials and Methods: retrospective cohort study was performed in 2020 in military medical centers affiliated to AJA University of Medical Sciences in Tehran on 220 patients with type 2 diabetes mellitus who were admitted in medical centers with COVID-19 infection. We collected demographic data of patients including age, gender, drug history, usage of DPP-4 inhibitors, clinical presentations at the time of the first visit, and the disease outcome including hospitalization duration and need for respiratory assist. Results: The study population consisted of 133 males (60.5%) and 87 females (39.5%), with a mean age of 66.13 ± 12.3 years. Forty-four patients (20%) consumed DPP-4 inhibitors (sitagliptin and linagliptin). Patients who were treated with DPP-4 inhibitors required less oxygen (O2) therapies compared to other cases (76.7% vs. 88.6%, P = 0.04). Patients who were treated with DPP-4 inhibitors had significantly lower hospitalization duration compared to other cases (6.57 ± 2.3 days vs. 8.03 ± 4.4 days, respectively, P = 0.01). There were no significant differences between the two groups of patients regarding survival rates (P = 0.55). Age was a predictive factor for survival (odds ratio, 1.13; 95% confidence interval, 1.04-1.23; P = 0.004). Conclusion: DPP-4 inhibitors could significantly decrease hospitalization days in patients with type 2 diabetes mellitus who were hospitalized for COVID-19. However, DPP-4 inhibitor usage showed no statistically significant impact on survival. Age was the important prognostic factor.
RESUMO
PURPOSE: Invasive aspergillosis is a prevalent fungal disease, especially in Asian countries with a high mortality rate. Voriconazole (VRZ) is the first choice for invasive aspergillosis treatment. Plasma concentration of this drug is unpredictable and varies among individuals. This variability is influenced by many factors leading to clinical implication. Therapeutic drug monitoring (TDM) may have a crucial role in the patients' treatment process. The HPLC method provides sufficient specificity and sensitivity for plasma VRZ concentration determination for TDM purposes of this drug. METHODS: Patients who initiated oral or intravenous VRZ for invasive aspergillosis were enrolled in this study. Demographic characteristics and clinical data, outcome, and adverse effects were documented. For each patient, the plasma sample was collected under steady-state condition and analyzed using a validated HPLC method. RESULTS: A total of 22 measurements were performed. Fifty percent of patients were out of the therapeutic range. From them, 27.27% and 22.73% were in subtherapeutic and supratherapeutic ranges (<1 µg/mL and >5.5 µg/mL), respectively. There was a significant correlation between VRZ plasma concentration and treatment outcomes (P=0.022). Treatment failure was five times higher than treatment success in those in the subtherapeutic range. Adverse effects were observed more frequently in patients with supratherapeutic concentrations compared to those with non-supratherapeutic levels. Furthermore, the mortality rate in patients experiencing treatment failure was 2.17 times higher than those with treatment success. CONCLUSIONS: TDM of VRZ plays an important role in better evaluation of efficacy and toxicity during treatment. Therefore, determination of the drug level may be of clinical significance.
RESUMO
INTRODUCTION: Venovenous extracorporeal membrane oxygenation (VV-ECMO) is a therapeutic strategy for the coronavirus disease 2019 (COVID-19) induced acute respiratory distress syndrome (ARDS). There are inconclusive data in this regard and causes of VV-ECMO failure are not yet understood well. CASE SERIES: Here, seven patients with COVID-19-induced ARDS who underwent VV-ECMO introduced and causes of VV-ECMO failure discussed. Medical records of seven COVID-19 patients treated with VV-ECMO were retrospectively evaluated to determine the clinical outcomes of VV-ECMO. Oxygenator failure occurred in four patients whom needed to oxygenator replacement. Successful VV-ECMO decannulation was done in three patients, however finally one patient survived. CONCLUSIONS: Hypercoagulability state and oxygenator failure were the most main etiologies for VV-ECMO failure in our study. All patients with COVID-19 undergoing VV-ECMO should be monitored for such problems and highly specialized healthcare team should monitor the patients during VV-ECMO.

AIM AND BACKGROUND: Propolis has been used for the management of oral mucositis in a number of studies. Due to lack of sufficient evidence especially in radiotherapy induced oral mucositis, the present study was designed to evaluate the efficacy and safety of propolis mouthwash in oral mucositis and dysphagia in patients undergoing head and neck radiotherapy. MATERIALS AND METHODS: This study was a prospective, randomised, double-blind, placebo-controlled trial. The patients randomly divided into two groups receiving either the propolis or the placebo mouthwash. Patients were advised to rinse their mouth with 15â¯mL three times daily for four weeks. Severity of mucositis and dysphagia were evaluated by the National Cancer Institute Common Toxicity Criteria (NCI-CTC) and Common Terminology Criteria for Adverse Events (CTCAE), respectively. RESULTS: Thirty patients completed the study. Each group consisted of 15 patients. Although, there is not any significant difference between two groups in the first week of radiotherapy, a significant difference was seen in the second, the third and the fourth week (pâ¯=â¯0.03, 0.02, 0.02, respectively). Dysphagia reported as a mild score in the propolis group only in the fourth week which is significant compared with the placebo group (pâ¯=â¯0.01). There is not any serious adverse effect related to propolis or placebo during the study. CONCLUSION: It seems that propolis mouthwash is an effective and safe medication for alleviation of oral mucositis and dysphagia in patients under head and neck radiotherapy.
RESUMO
Chronic Obstructive Pulmonary Disease (COPD) is associated with increased inflammatory responses to noxious particles, which can be further enhanced during Acute Exacerbation of COPD (AECOPD). Considering the important immunoregulatory function of vitamin D, high prevalence of Vitamin D Deficiency (VDD) in COPD patients and a negative link between vitamin D levels and inflammatory biomarkers, suggests the seemingly interesting mechanism of vitamin D effects on inflammation resolution during the conventional treatment of AECOPD. The admitted AECOPD patients with VDD were recruited and randomly allocated to receive either 300,000 IU of intramuscular vitamin D (n = 35) or placebo (n = 35). Primary outcomes included inflammation resolution dynamics, which were assessed by monitoring the serum levels of IL-6, IL-8, and hs-CRP. Symptom recovery was evaluated based on the modified Medical Research Council (mMRC) dyspnea scale on the 1st and 6th days of admission. Secondary outcomes included the length of hospital stay (LOS) and 30-day mortality rates. Inflammatory biomarkers were highest at Day 1. Baseline vitamin D levels were 11.25 ± 3.09 and 10.59 ± 3.90 ng/ml (P = 0.45), which reached 11.35 ± 3.16 and 18.17 ± 4.24 by Day 6 (P < 0.001) in the placebo and, vitamin-D groups, respectively. IL-6 levels significantly decreased in the vitamin-D vs. placebo group on the 6th day (P = 0.02); however, no significant differences were observed in IL-8 (P = 0.15) and hs-CRP (P = 0.24) levels, mMRC scale (P = 0.45), LOS (P = 0.20), and mortality rates (P = 0.61). Vitamin D replacement as adjunctive therapy may accelerate inflammation resolution in hospitalized AECOPD patients. Further studies were needed to establish vitamin D exact role on inflammation resolution in AECOPD.

OBJECTIVE: A case with reversible symmetrical sensorineural hearing loss following hydroxychloroquine therapy is described. CASE SUMMARY: A 57-year-old, human immunodeficiency virus (HIV) positive man was referred to the HIV clinic of Imam Khomeini Hospital, Tehran with chief complaint of bilateral slowly progressive hearing loss starting from two months ago. The man had history of rheumatoid arthritis diagnosed from 3 months ago and was administered hydroxychloroquine 200 mg and prednisolone 5 mg twice daily. Audiometry test showed moderate to severe neuronal hearing loss and reduced speech recognition in both ears of the patient. With suspicion of hydroxychloroquine-induced hearing loss, this drug was discontinued. After 2 months of hydroxychloroquine discontinuation, his audiometry findings were improved. DISCUSSION: A few cases of hydroxychloroquine-induced hearing loss have been reported. All of the cases were non-HIV positive individuals. Irreversible hearing loss was developed following long-term therapy with hydroxychloroquine. The present case was a HIV-positive man who developed hearing loss following short course (one month) hydroxychloroquine therapy and his problem was resolved following discontinuation of hydroxychloroquine and continuation of prednisolone. CONCLUSIONS: Hydroxychloroquine-induced hearing loss may reversibly occur following short term therapy in HIV patients.
RESUMO
Background: Hematopoietic stem cell transplantation (HSCT) patients are at risk of thromboembolic events, making thromboprophylaxis crucial. Objectives: This study aimed to compare apixaban, a direct factor Xa inhibitor (DOAC), with dalteparin and unfractionated heparin for thromboprophylaxis in HSCT recipients. The safety outcome included the assessment of hemorrhagic events. Methods: In this open-label randomized clinical trial, 182 HSCT recipients were divided into three groups: Apixaban (n = 61, 2.5 mg two times a day), dalteparin (n = 59, 5000 IU daily), and unfractionated heparin (n = 62, 5000 IU twice daily). These anticoagulant regimens were administered after central vein catheterization and during hospitalization. The primary clinical outcome was the risk of thrombosis, and the secondary outcome was the rate of bleeding. Relevant laboratory results were analyzed using appropriate statistical tests. Results: Among the 61 patients in the apixaban group, six experienced thrombosis (9.83%), with four (6.65%) of them on anticoagulants. In the dalteparin group, three patients (5%) developed thrombosis, two of whom (3.38%) were on anticoagulants. In the heparin group, all four thrombosis cases (6.4%) occurred in patients on anticoagulants (P = 0.543 overall and P = 0.776 in anticoagulant users). Only two cases of bleeding were reported (1.09% overall), one in the dalteparin group (1.69%) and the other in the apixaban group (1.63%). Conclusions: Apixaban, dalteparin, and heparin demonstrated similar effectiveness in preventing thromboembolism in HSCT recipients. Furthermore, the comparison of bleeding rates across the study groups did not reveal significant differences. Larger studies with higher event rates may yield more precise conclusions.
RESUMO
Background and purpose: Though controversial, many clinical trials have been conducted to evaluate the efficacy of intravenous immunoglobulins (IVIG) in COVID-19 cases. Therefore, a systematic review and meta-analysis have been performed to evaluate the efficacy of IVIG in the treatment of COVID-19 patients. Experimental approach: A systematic search was performed in electronic databases and preprint servers up to November 20, 2021. Since substantial heterogeneity was expected, a random-effects model was applied to pool effect size from included studies to calculate the standardized mean differences (SMDs) for the continuous variables and relative risks (RRs) for the dichotomous variable with 95% confidence intervals (CIs). Findings/Results: Five randomized clinical trials and seven cohort studies were analyzed among the 12 eligible studies with a total of 2,156 patients. The pooled RR of mortality was 0.77 (CI 0.59-1.01, P-value = 0.06), and of mechanical ventilation was 1.50 (CI 0.29-7.83; P-value = 0.63) in the IVIG group compared with the standard care group. The pooled SMD of hospital length of stay was 0.84 (CI -0.43-2.11; P-value = 0.20) and of ICU length of stay was -0.07 (CI -0.92-0.78; P-value = 0.86) in the IVIG group compared with the standard care group. Conclusion and implications: This meta-analysis found that the IVIG therapy was not statistically different from the standard care group. Mortality, ICU admission, mechanical ventilation, length of hospital stay, and length of ICU stay were not significantly improved among IVIG recipients. However, statistical indifference is not equal to clinical indifference.
RESUMO
BACKGROUND: Bromhexine is a potent inhibitor of transmembrane serine protease 2 and appears to have an antiviral effect in controlling influenza and parainfluenza infection; however, its efficacy in COVID-19 is controversial. METHODS: A group of hospitalized patients with confirmed COVID-19 pneumonia were randomized using 1:1 allocation to either standard treatment lopinavir/ritonavir and interferon beta-1a or bromhexine 8 mg four times a day in addition to standard therapy. The primary outcome was clinical improvement within 28 days, and the secondary outcome measures were time to hospital discharge, all-cause mortality, duration of mechanical ventilation, the temporal trend in 2019-nCoV reverse transcription-polymerase chain reaction positivity and the frequency of adverse drug events within 28 days from the start of medication. RESULTS: A total of 111 patients were enrolled in this randomized clinical trial and data from 100 patients (48 patients in the treatment arm and 52 patients in the control arm) were analyzed. There was no significant difference in the primary outcome of this study, which was clinical improvement. There was no significant difference in the average time to hospital discharge between the two arms. There were also no differences observed in the mean intensive care unit stay, frequency of intermittent mandatory ventilation, duration of supplemental oxygenation or risk of death by day 28 noted between the two arms. CONCLUSION: Bromhexine is not an effective treatment for hospitalized patients with COVID-19. The potential prevention benefits of bromhexine in asymptomatic postexposure or with mild infection managed in the community remain to be determined.

BACKGROUND AND AIM: Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by the obstruction of the main pulmonary artery due to thrombosis and vascular remodeling. Regarding the need for anticoagulant therapy in CTEPH patients, this study aimed to compare rivaroxaban with warfarin in terms of its efficacy and safety in patients undergoing endarterectomy surgery. METHODS: The study was a parallel clinical trial in patients who underwent endarterectomy following CTEPH. A total of 96 patients were randomly selected and assigned to two groups: warfarin-treated (control) and rivaroxaban-treated (intervention). Patients were clinically assessed for re-thrombosis, re-admission, bleeding, and mortality in the first, third, and sixth months after surgery. RESULTS: There was no significant difference in the occurrence of thrombosis between the two groups within the first, third-, and sixth-months post-surgery (p=0.52, 1, 0.38 respectively). Moreover, the mortality rate (p=0.9), bleeding rate (p=0.06), and re-admission rate (p=0.15) showed no significant differences between the two groups. CONCLUSION: Rivaroxaban may be as effective as warfarin in treating CTEPH patients after endarterectomy in the short term and can be used as an anticoagulant in these patients. However, studies with long-term follow-ups are needed to consolidate the strategy of treating these patients with rivaroxaban.

Background: As February 2023, SARS-CoV-2 is still infecting people and children worldwide. Cough and dyspnea are annoying symptoms almost present in a large proportion of COVID-19 outpatients, and the duration of these symptoms might be long enough to affect the patients' quality of life. Studies have shown positive effects for noscapine plus licorice in the previous COVID-19 trials. This study aimed to assess the effects of the combination of noscapine and licorice-for relieving cough in outpatients with COVID-19. Methods: This randomized controlled trial was conducted on 124 patients at the Dr. Masih Daneshvari Hospital. Participants over 18 years of age with confirmed COVID-19 and cough were allowed to enter the study if the onset of symptoms was less than 5 days. The primary outcome was to assess the response to treatment over 5 days using the visual analogue scale. Secondary outcomes included the assessment of cough severity after 5 days using Cough Symptom Score, as well as the cough-related quality of life and dyspnea relieving. Patients in the noscapine plus licorice group received Noscough® syrup 20 mL every 6 h for 5 days. The control group received diphenhydramine elixir 7 mL every 8 h. Results: By day five, 53 (85.48%) patients in the Noscough® group and 49 (79.03%) patients in the diphenhydramine group had response to treatment. This difference was not statistically significant (p-value = 0.34). The presence of dyspnea was significantly lower in the Noscough® group versus diphenhydramine at day five (1.61% in the Noscough® group vs. 12.9% in the diphenhydramine group; p-value = 0.03). The cough-related quality of life and severity also significantly favored Noscough® syrup (p-values <0.001). Conclusion: Noscapine plus licorice syrup was slightly superior to diphenhydramine in relieving cough symptoms and dyspnea in the COVID-19 outpatients. The severity of cough and cough-related quality of life were also significantly better in the noscapine plus licorice syrup. Noscapine plus licorice may be a valuable treatment in relieving cough in COVID-19 outpatients.
RESUMO
Background: Tocilizumab and baricitinib are considered standard treatments for hospitalized COVID-19 patients with an inflammatory status. However, the effects of co-administering these medications aiming for more rapid patient recovery are controversial among practitioners. The potential benefits include the rapid improvement of patients and regulation of the immune system, and the potential risks include the increased chance of serious adverse events, including infections. This study aimed to investigate the effects of co-administering these two medications on the 28-day mortality rate, other efficacy parameters, and safety issues. Methods: In this randomized open-label trial, 68 patients were recruited. The study was conducted at Dr. Masih Daneshvari Hospital during 6 months (from 21 March 2022 to 23 August 2022). Severely ill patients aged between 18 and 100 years old with confirmed COVID-19 were enrolled. The primary outcomes included the need for invasive mechanical ventilation and a 28-day mortality rate. Secondary outcomes included the need for non-invasive mechanical ventilation, the need for admission to the intensive care unit (ICU), the length of hospital stay, and the need for a second dose of tocilizumab. Safety assessments were also performed for 28 days. The data were collected from the patients' medical records, which included age, gender, and comorbidities. Results: The 28-day mortality rate or the need for mechanical ventilation was not statistically different among the two groups (p-value = 0.49 for both outcomes). The need for non-invasive mechanical ventilation, the need for admission to the ICU, or the need for a second dose of tocilizumab and the length of hospital stay was not affected either (p-value = 1; 0.1; 0.49 and 0.9, respectively). One patient developed thrombosis in the combination group. No adverse events related to infectious complications were recorded in any groups. Conclusion: This study showed no beneficial effects of combining tocilizumab and baricitinib in managing severe COVID-19 cases. However, the need for ICU admission was meaningfully lower in the combination group. Studies with larger sample sizes are needed to confirm these results. Clinical Trial Registration: Identifier: RCT20151227025726N30M.
RESUMO
Background: Pseudomonas aeruginosa is the most common microorganism found in the sputum culture of Cystic fibrosis (CF) patients causing the pulmonary destruction. Aminoglycosides have a low diffuse rate from lipid membranes, and respiratory system secretions. Regarding the burden of pulmonary exacerbation caused by the pseudomonas aeruginosa in cystic fibrosis patients in the long term and the limited number of clinical trials focused on appropriate treatment strategies, the present study evaluated the concurrent inhaled and intravenous aminoglycoside antibiotics for pulmonary exacerbation caused by the pseudomonas aeruginosa as a safe and effective treatment in children. Method: This study was a blinded, randomized clinical trial phase conducted in a tertiary referral pediatric teaching hospital from May 2021 to May 2022. The patients were randomly allocated to receive intravenously administered ceftazidime and Amikacin alone or with inhaled Amikacin. Forced expiratory volume (FEV1), Amikacin via the level, kidney function tests, audiometry, inflammatory markers (erythrocyte sedimentation rate and C-reactive protein), hospital stay, and bacterial eradication rate were compared in two therapy groups. Results: the average FEV1 has increased by 47% in Neb + group compared to Neb- group following treatment. Hospital stay was lower in Neb + group. No renal toxicity or ototoxicity was observed in both therapy groups. Pseudomonas aeruginosa eradication rate Neb- and Neb + groups were 44% and 69%, respectively (p-value = 0.15). Conclusion: Concurrent inhaled and intravenous Amikacin is safe and effective to treat Pseudomonas aeruginosa exacerbation in CF patients. Moreover, co-delivery antibiotics' route treatment increased the eradication rate. Although not statistically significant, never the less, it is clinically relevant. The intervention reduced the length of hospitalization in this group. Clinical Trial Registration: clinicaltrials.gov, identifier [IRCT20120415009475N10].
RESUMO
Background: The symptoms of pulmonary sarcoidosis may lead to fatigue, excessive daytime sleepiness, poor sleep quality, and a decrease in quality of life in these patients. Objectives: This study was designed to evaluate the effects of oral melatonin on sleep disorders of patients with pulmonary sarcoidosis. Methods: A randomized, single-blinded clinical trial was conducted on patients with pulmonary sarcoidosis. Eligible patients were randomly allocated into melatonin and control groups. Patients in the melatonin group were given 3 mg melatonin one hour before bedtime for three months. Sleep quality, daytime sleepiness, fatigue status, and quality of life were assessed applying General Sleep Disturbance Scale (GSDS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Fatigue Assessment Scale (FAS), and the Patient-Reported Outcomes Measurement Information System (PROMIS), respectively, as well as the 12-item Short Form Survey (SF-12) scores at the baseline and three months after treatment. Results: There was a significant change in the GSDS (P < 0.001), PSQI (P < 0.001), ESS (P = 0.002), and FAS (P < 0.001) scores, which were decreased, compared to those of the control group. After intervention¸ global physical health and global mental health raw scores were improved comparing to the control group (P = 0.006, P = 0.02, respectively). The 12-item Short Form Survey evaluation showed that there was a significant difference between the melatonin (3.38 ± 4.61) and control (0.55 ± 7.25) groups in PCS-12 score after three months of therapy (P = 0.02). Conclusions: Our findings showed that supplemental melatonin could significantly improve sleep problems, quality of life, and excessive daytime sleepiness in sarcoidosis patients.
RESUMO
Behçet's disease (BD) is a multisystem, progressive, and inflammatory disorder of unknown etiology. Vasculitis is believed to underlie various clinical manifestations of BD and is known to be one of the main causes of death due to BD, in cases of large vessel involvement. The current study is done in order to examine the effects of rituximab on the patient's debilitating clinical manifestations, as a result of not responding to the standard treatment regimens. The present case is a 28-year-old female patient with BD associated vasculitis. She was referred to the respiratory referral center, chiefly complaining of intermittent episodes of massive hemoptysis. She had also recurrent oral and genital ulcers, and difficulty in walking, despite considering the common treatment approaches for BD. Our patient received two courses of rituximab in combination with intravenous methylprednisolone. Over six months follow-up period from the date of treatment initiation with rituximab, symptoms of BD such as recurrent hemoptysis and aphthous ulcers were reduced in both frequency and severity. Lower limb weakness and difficulty in walking were improved as well. To summarize, rituximab appears to be an effective alternative for treatment-resistant vasculitis in BD patients.
