Renal Failure Dec 2023To investigate the effects of low-dose furosemide and aminophylline on the renal function in patients with septic shock. (Randomized Controlled Trial)
Randomized Controlled Trial
BACKGROUND
To investigate the effects of low-dose furosemide and aminophylline on the renal function in patients with septic shock.
METHODS AND RESULTS
A total of 109 eligible septic shock patients in the intensive care unit were randomly divided into a control group ( = 55) and an intervention group ( = 54). The control group received normal saline, and the intervention group received low-dose furosemide (0.048 mg/kg.h) with aminophylline (0.3 mg/kg.h). The primary outcomes included the levels of serum creatinine (Scr), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), glomerular filtration rate (GFR), and urine output on admission and on days 3, 7 and 14. The secondary outcomes were the sequential organ failure assessment (SOFA) scores, continuous renal replacement therapy (CRRT) time and intensive care unit (ICU) mortality, hospital mortality and 28-day mortality. There were no significant differences in the levels of Scr, Ccr, BUN, or GFR between the two groups, while the urine output was higher in the intervention group on days 3, 7, and 14. Compared with the control group, the SOFA scores, ICU mortality, hospital mortality and 28-day mortality were significantly lower in the intervention group on days 3, 7, and 14, the CRRT time was shorter, and the cumulative fluid balance was lower on days 3 and 7 in the intervention group.
CONCLUSIONS
Although low-dose furosemide and aminophylline have fewer protective effects on the renal function in septic shock patients, they could reduce the CRRT time and improve the prognosis.

Review
BACKGROUND
Asthma is the most common chronic disease of childhood and a major source of childhood health burden worldwide. These burdens are particularly marked when children experience characteristic 'symptom flare-ups' or acute asthma exacerbations (AAEs). AAE are associated with significant health and economic impacts, including acute Emergency Department visits, occasional hospitalizations, and rarely, death. To treat children with AAE, several medications have been studied and used.
METHODS
We conducted a narrative review of the literature with the primary objective of understanding the evidence of their efficacy. We present this efficacy evidence in the context of a general stepwise management pathway for paediatric AAEs. This framework is developed from the combined recommendations of eight established (inter)national paediatric guidelines.
DISCUSSION
Management of paediatric AAE centres around four major care goals: (1) immediate and objective assessment of AAE severity; (2) prompt and effective medical interventions to decrease respiratory distress and improve oxygenation; (3) appropriate disposition of patient; and (4) safe discharge plans. Several medications are currently recommended with varying efficacies, including heliox, systemic corticosteroids, first-line bronchodilators (salbutamol/albuterol), adjunctive bronchodilators (ipratropium bromide, magnesium sulfate) and second-line bronchodilators (aminophylline, i.v. salbutamol, i.v. terbutaline, epinephrine, ketamine). Care of children with AAE is further enhanced using clinical severity scoring, pathway-driven care and after-event discharge planning.
CONCLUSIONS
AAEs in children are primarily managed by medications supported by a growing body of literature. Continued efforts to study the efficacy of second-line bronchodilators, integrate AAE management with long-term asthma control and provide fair/equitable care are required.

Review
Adult bronchial asthma is characterized by chronic airway inflammation, and presents clinically with variable airway narrowing (wheezes and dyspnea) and cough. Long-standing asthma induces airway remodeling, leading to intractable asthma. The number of patients with asthma has increased; however, the number of patients who die of asthma has decreased (1.2 per 100,000 patients in 2015). The goal of asthma treatment is to enable patients with asthma to attain normal pulmonary function and lead a normal life, without any symptoms. A good relationship between physicians and patients is indispensable for appropriate treatment. Long-term management by therapeutic agents and elimination of the causes and risk factors of asthma are fundamental to its treatment. Four steps in pharmacotherapy differentiate between mild and intensive treatments; each step includes an appropriate daily dose of an inhaled corticosteroid, varying from low to high levels. Long-acting β-agonists, leukotriene receptor antagonists, sustained-release theophylline, and long-acting muscarinic antagonist are recommended as add-on drugs, while anti-immunoglobulin E antibody and oral steroids are considered for the most severe and persistent asthma related to allergic reactions. Bronchial thermoplasty has recently been developed for severe, persistent asthma, but its long-term efficacy is not known. Inhaled β-agonists, aminophylline, corticosteroids, adrenaline, oxygen therapy, and other approaches are used as needed during acute exacerbations, by choosing treatment steps for asthma in accordance with the severity of exacerbations. Allergic rhinitis, eosinophilic chronic rhinosinusitis, eosinophilic otitis, chronic obstructive pulmonary disease, aspirin-induced asthma, and pregnancy are also important issues that need to be considered in asthma therapy.

Review
BACKGROUND
Electroconvulsive therapy (ECT) is a highly efficacious treatment modality used to produce seizures in patients diagnosed with major depressive disorders and psychotic episodes. In general, ECT treatment is successful in most patients; however, in some populations, ECT fails to produce adequate response. Caffeine, theophylline, and aminophylline are documented to augment seizure activity in ECT. By inhibiting adenosine, these medications can improve ECT response rate in a certain patient population. Caffeine and aminophylline have been documented to prolong seizure duration. Theophylline has been shown to improve seizure duration along with decreasing seizure threshold. All of these medications have very minimal side effect profiles. This review will discuss up-to-date evidence on the effects of xanthine derivatives in patients receiving ECT treatment.
METHODS
A literature review of PubMed and EMBASE was performed for related studies.
RESULTS
Eight studies were included in our review. Premedication with caffeine, theophylline, or aminophylline was associated with increased seizure duration in patients suffering from mental disorders and were indicated to manage ECT.
CONCLUSION
Xanthine derivatives prolong seizure duration in patients treated with ECT.

Meta-Analysis Review
BACKGROUND
In cardiac ischaemia, the accumulation of adenosine may lead to or exacerbate bradyasystole and diminish the effectiveness of catecholamines administered during resuscitation. Aminophylline is a competitive adenosine antagonist. Case studies suggest that aminophylline may be effective for atropine-resistant bradyasystolic arrest.
OBJECTIVES
To determine the effects of aminophylline in the treatment of patients in bradyasystolic cardiac arrest, primarily survival to hospital discharge. We also considered survival to admission, return of spontaneous circulation, neurological outcomes and adverse events.
SEARCH METHODS
For this updated review, we searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, LILACS, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform in November 2014. We checked the reference lists of retrieved articles, reviewed conference proceedings, contacted experts and searched further using Google.
SELECTION CRITERIA
All randomised controlled trials comparing intravenous aminophylline with administered placebo in adults with non-traumatic, normothermic bradyasystolic cardiac arrest who were treated with standard advanced cardiac life support (ACLS).
DATA COLLECTION AND ANALYSIS
Two review authors independently reviewed the studies and extracted the included data. We contacted study authors when needed. Pooled risk ratio (RR) was estimated for each study outcome. Subgroup analysis was predefined according to the timing of aminophylline administration.
MAIN RESULTS
We included five trials in this analysis, all of which were performed in the prehospital setting. The risk of bias was low in four of these studies (n = 1186). The trials accumulated 1254 participants. Aminophylline was found to have no effect on survival to hospital discharge (risk ratio (RR) 0.58, 95% confidence interval (CI) 0.12 to 2.74) or on secondary survival outcome (survival to hospital admission: RR 0.92, 95% CI 0.61 to 1.39; return of spontaneous circulation: RR 1.15, 95% CI 0.89 to 1.49). Survival was rare (6/1254), making data about neurological outcomes and adverse events quite limited. The planned subgroup analysis for early administration of aminophylline included 37 participants. No one in the subgroup survived to hospital discharge.
AUTHORS' CONCLUSIONS
The prehospital administration of aminophylline in bradyasystolic arrest is not associated with improved return of circulation, survival to admission or survival to hospital discharge. The benefits of aminophylline administered early in resuscitative efforts are not known.

Review
UNLABELLED
The diuretic effect of the combined furosemide and aminophylline/theophylline among pediatric patients remains unclear. The primary aim of this systematic review was to examine the clinical diuretic effects (urine output and fluid balance) of co-administration of furosemide and aminophylline/theophylline as compared to furosemide alone in pediatric population. Ovid MEDLINE, CENTRAL, and EMBASE were searched from its inception until March 2022 for observational studies and randomized controlled trials (RCTs) comparing the administration of furosemide versus furosemide and aminophylline/theophylline in pediatric population. Case reports, case series, commentaries, letters to editors, systematic reviews, and meta-analyses were excluded. Five articles with a total sample population of 187 patients were included in this systematic review. As compared to the furosemide alone, our pooled data demonstrated that co-administration of furosemide and aminophylline/theophylline was associated with higher urine output (mean difference: 2.91 [90% CI 1.54 to 4.27], p < 0.0001, I = 90%) and a more negative fluid balance (mean difference - 28.27 [95% CI: - 46.21 to - 10.33], p = 0.002, I = 56%) than those who received furosemide alone.
CONCLUSION
This is the first paper summarizing the evidence of combined use of furosemide with aminophylline/theophylline in pediatric population. Our systematic review demonstrated that the co-administration of furosemide and aminophylline/theophylline could potentially yield better diuretic effects of urine output and negative fluid balance than furosemide alone in pediatric patients with fluid overload. Given the substantial degree of heterogeneity and low level of evidence, future adequately powered trials are warranted to provide evidence regarding the combined use of aminophylline/theophylline and furosemide as diuretic in the pediatric population.
WHAT IS KNOWN
• Fluid overload is associated with poor prognosis for children in the intensive care unit. • The ineffective result of furosemide alone, even at high dose, as diuretic agent for children with diuretic resistant fluid overload in the intensive care unit.
WHAT IS NEW
• This is the first systematic review that compares furosemide alone and co-administration of furosemide and aminophylline/theophylline. • This paper showed potential benefit of co-administration of furosemide and aminophylline/theophylline promoting urine output and negative fluid balance compared to furosemide alone.

Effect of Intravenous Aminophylline on Hemodynamics and Recovery of Patients Undergoing Functional Endoscopic Sinus Surgery Under Dexmedetomidine Hypotensive Anesthesia: A Randomized Controlled Study.
BACKGROUND
The sympatholytic property of dexmedetomidine (DEX) makes it suitable as a hypotensive drug during functional endoscopic sinus surgery (FESS); however, delayed emergence from anesthesia and high postoperative sedation have been reported.
OBJECTIVES
Delayed emergence from anesthesia and high postoperative sedation are associated with a prolonged length of stay in the operating room and the postanesthesia care unit (PACU), which increases health care costs. This study aimed to overcome the negative impact of DEX on recovery by using aminophylline.
METHODS
This randomized, double-blind, placebo-controlled study was conducted on 52 patients planned for elective FESS under general anesthesia with DEX infusion for controlled hypotension during surgery. Patients were equally divided into 2 groups. The aminophylline group received 4 mg/kg aminophylline diluted in 50 mL saline 0.9% over 30 minutes after positioning in a 20-degree reverse Trendelenburg position. The control group received 50 mL saline 0.9% with a similar volume and period as the aminophylline group.
RESULTS
The extubation time was significantly shorter in the aminophylline group (6.5 (5.25 - 7.75) minutes) than in the control group (9 (7.25 - 10) minutes) (P-value < 0.001). The PACU discharge time was significantly shorter in the aminophylline group (15 (10 - 20) minutes) compared to the control group (20 (15 - 28.75) minutes) (P-value = 0.036). Intraoperative heart rate and mean arterial pressure were nonsignificantly different between the 2 groups. Ramsay sedation score measurements at 15 min, 30 min, and 60 min after extubation were significantly lower in the aminophylline than in the control group (P-value < 0.05). Complications were nonsignificantly different between the 2 groups.
CONCLUSIONS
Intraoperative aminophylline infusion enhances the recovery of patients undergoing FESS under DEX hypotensive anesthesia without intraoperative hemodynamic alterations and decreases their postoperative sedation without significant postoperative side effects.

Chronic renal failure (CRF) is a severe syndrome affecting the urinary system for which there are no effective therapeutics. In this study, we investigate the effects and mechanisms of aminophylline in preventing CRF development. A rat model of chronic renal failure is established by 5/6 nephrectomy. The levels of serum creatinine (SCR), urinary protein (UPR), and blood urea nitrogen (BUN) are detected by ELISA. Histological evaluations of renal tissues are performed by H&E, Masson staining, and PAS staining. Functional protein expression is detected by western blot analysis or immunofluorescence microscopy. Glomerular cell apoptosis is determined using the TUNEL method. Results show that Aminophylline significantly reduces the levels of SCR, UPR, and BUN in the CRF model rats. Histological analyses show that aminophylline effectively alleviates renal tissue injuries in CRF rats. The protein expression levels of nephrin, podocin, SIRT1, p-AMPK, and p-ULK1 are greatly increased, while p-mTOR protein expression is markedly decreased by aminophylline treatment. Additionally, the protein level of LC3B in CRF rats is significantly increased by aminophylline. Moreover, aminophylline alleviates apoptosis in the glomerular tissues of CRF rats. Furthermore, resveratrol promotes SIRT1, p-AMPK, and p-ULK1 protein expressions and reduces p-mTOR and LC3B protein expressions in CRF rats. Selisistat (a SIRT1 inhibitor) mitigates the changes in SIRT1, p-AMPK, p-ULK1, p-mTOR, and LC3B expressions induced by aminophylline. Finally, RAPA alleviates renal injury and apoptosis in CRF rats, and 3-MA eliminates the aminophylline-induced inhibition of renal injury and apoptosis in CRF rats. Aminophylline suppresses chronic renal failure progression by modulating the SIRT1/AMPK/mTOR-mediated autophagy process.

Randomized Controlled Trial
BACKGROUND
Sepsis is a serious disease caused by infection. Aminophylline has anti-asthma and anti-inflammatory effects. We aimed to explore the safety and effect of aminophylline in sepsis.
METHODS
We conducted a clinical randomized controlled trial involving 100 patients diagnosed with sepsis within 48 h after intensive care unit (ICU) admission in two sites. All patients were randomized in a 1:1 ratio to receive standard therapy with or without aminophylline. The primary clinical outcome was all-cause mortality at 28 days.
RESULTS
From September 27, 2018 to February 12, 2020, we screened 277 septic patients and eventually enrolled 100 patients, with 50 assigned to the aminophylline group and 50 to the usual-care group. At 28 days, 7 of 50 patients (14.0%) in the aminophylline group had died, compared with 16 of 50 (32.0%) in the usual-care group ( P = 0.032). Cox regression showed that the aminophylline group had a lower hazard of death (hazard ratio = 0.312, 95% confidence interval: 0.129-0.753). Compared with the usual-care group, patients in the aminophylline group had a longer survival time ( P = 0.039 by the log-rank test). The effects of aminophylline on vasopressor dose, oxygenation index, and sequential organ failure assessment score were time-dependent with treatment. There were no significant differences in total hospitalization days, ICU hospitalization days, and rates of serious adverse events (all P > 0.05). No adverse events were observed in the trial.
CONCLUSIONS
Aminophylline as an adjunct therapy could significantly reduce the risk of death and prolong the survival time of patients with sepsis.

OBJECTIVES
Post-dural Puncture Headache (PDPH) is prevalent among individuals undergoing lumbar punctures. The non-invasive effect of some drugs, such as aminophylline on PDPH has been investigated in several clinical studies. As there is no comprehensive systematic review and meta-analysis about the preventive and therapeutic effects of aminophylline on PDPH in the literature, the clinical effectiveness of this drug on the prevention and/or treatment of PDPH will be assessed in this study.
METHODS
PubMed/MEDLINE, Embase, WoS (Clarivate Analytics), the Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL Complete, Scopus, and Google Scholar as electronic databases will be precisely searched for clinical studies that assessed the effect of aminophylline on PDPH. Studies between 01-01-1980 and 30-06-2020 will be evaluated in this study, and there will not be any language restrictions. Contradictions between the reviewers within any phase of the study (screening, selecting, quality assessment, and data extraction) will be resolved by consensus; in case of unsolved disagreements, a third reviewer will eventually decide. The combination method will be applied according to the methodological resemblance in the selected articles using the Random Effect Model or the Fixed Effect Model. Also, for the included articles, forest plots will be drawn. For assessing statistical heterogeneity, the I statistic and the Q-statistic test will be applied. In addition, funnel plots will be used for assessing non-significant study effects and potential reporting bias. Furthermore, Egger's and Begg's tests will be done, and publication bias will be indicated by significant findings (P < 0.05).
CONCLUSIONS
It is expected that the results of this study will be of benefit to researchers and clinicians for managing PDPH, and will be reported in conferences and publications.
