Investigating the risk of deep vein thrombosis with JAK inhibitors: a disproportionality analysis using FDA Adverse Event Reporting System Database (FAERS)

Safety Profile of Selective Serotonin Reuptake Inhibitors in Real-World Settings: A Pharmacovigilance Study Based on FDA Adverse Event Reporting System

BACKGROUND

Selective serotonin reuptake inhibitors (SSRIs) are the most frequently prescribed agents to treat depression. Considering the growth in antidepressant prescription rates, SSRI-induced adverse events (AEs) need to be comprehensively clarified.

OBJECTIVE

This study was to investigate safety profiles and potential AEs associated with SSRIs using the Food and Drug Administration Adverse Event Reporting System (FAERS).

METHODS

A retrospective pharmacovigilance analysis was conducted using the FAERS database, with Open Vigil 2.1 used for data extraction. The study included cases from the marketing date of each SSRI (ie, citalopram, escitalopram, fluoxetine, paroxetine, fluvoxamine, and sertraline) to April 30, 2023. We employed the reporting odds ratio and Bayesian confidence propagation neural network as analytical tools to assess the association between SSRIs and AEs. The Medical Dictionary for Regulatory Activities was used to standardize the definition of AEs. AE classification was achieved using system organ classes (SOCs).

RESULTS

Overall, 427 655 AE reports were identified for the 6 SSRIs, primarily associated with 25 SOCs, including psychiatric, nervous system, congenital, familial, genetic, cardiac, and reproductive disorders. Notably, sertraline (n = 967) and fluvoxamine (n = 169) exhibited the highest and lowest signal frequencies, respectively. All SSRIs had relatively strong signals related to congenital, psychiatric, and nervous disorders.

CONCLUSIONS AND RELEVANCE

Most of our findings are consistent with those reported previously, but some AEs were not previously identified. However, AEs attributed to SSRIs remain ambiguous, warranting further validation. Applying data-mining methods to the FAERS database can provide additional insights that can assist in appropriately utilizing SSRIs.

The Association Between Deep Vein Thrombosis, Pulmonary Embolism, and Janus Kinase Inhibitors: Reporting Status and Signal Detection in the Japanese Adverse Drug Event Report Database

BACKGROUND

Although Janus kinase (JAK) inhibitors have expanding indications, deep vein thrombosis (DVT) and pulmonary embolism (PE) are serious adverse events associated with their use. Moreover, their analysis using the Japanese database of spontaneous adverse drug reaction reports has not yet been conducted.

OBJECTIVE

The objective of this study was to analyze the Japanese Adverse Drug Event Report database (JADER) to evaluate the association between JAK inhibitors and DVT and PE.

METHODS

JADER reports from April 2004 to October 2023 were analyzed. A classification of reports for the period covered was performed by drug, and an imbalance analysis was performed with oral JAK inhibitors as the target drug and DVT, PE, and "embolic and thrombotic events, venous" (Standardised MedDRA Query; SMQ) as the target adverse events. Reported odds ratios (ROR) and information components (IC) were calculated for signal detection.

RESULTS

Overall, 6631 JAK inhibitor-related adverse events were reported, including 60 and 41 cases of DVT and PE, respectively. The ROR and IC of the JAK inhibitors for DVT were 2.52 (1.95-3.25) and 1.27 (0.41-2.13), while those of baricitinib for DVT were 4.37 (2.83-6.73) and 1.90 (0.47-3.33), respectively. ROR signals were detected for JAK inhibitors for PE and "embolic and thrombotic events, venous (SMQ)," overall and for several JAK inhibitors but none for IC.

CONCLUSIONS

Several JAK inhibitors are under postmarketing phase vigilance, and the number of reported adverse events is low. However, when administering these drugs, care should be taken to avoid the development of thromboembolism, considering the patient's background.

Combination therapy of high-dose intravenous anakinra and baricitinib in patients with critical COVID-19: Promising results from retrospective observational study

INTRODUCTION

In this study, we aimed to evaluate the safety and efficacy of combination treatment of high-dose intravenous anakinra and baricitinib in patients with critically ill COVID-19.

MATERIAL AND METHODS

This retrospective observational study was conducted in a tertiary center with diagnosis of COVID-19 patients.Study population consisted of patients with positive polymerase chain reaction and computer tomography findings compatible with COVID-19 as well as critical illness.

RESULTS

Data of 15 patients in combination group and 43 patients in control group were evaluated and included into the study. Overall mortality was 46.7 % (n = 7) in combination arm and 69.8 % (n = 30) in control group although it was not statistically significant (p = 0.1). Similarly, need of intubation was also lower in combination arm (46.7 %) compared to control group (69.8 %), it was not significantly different (p = 0.1). ICU admission was significantly lower in combination (46.7 %, n = 7) arm than control group (76.7 %, n = 33) (p = 0.03, Odds ratio [OR]:4.7). Development of severe infection (20 %, n = 3 vs 25 %, n = 9/36), pulmonary embolism (6.7 %, n = 1 vs 0), myocardial infarction (6.7 %, n = 1 vs 2.6 %, n = 1/38) and pneumothorax (13.3 %, n = 2 vs 2.6 %, n = 1/38) were not different between two groups (p = 0.7, p = 0.3, p = 0.5 and p = 0.2). In multivariable analysis only cHIS score was associated with high mortality (p = 0.018, OR:2.8, [95 % confidence interval: 1.2-6.6]). In survival analysis, mortality rate was significantly lower in combination arm than control group (Log-Rank:p = 0.04).

CONCLUSION

Combination therapy of high-dose anakinra and baricitinib may be an adequate treatment option in patients with COVID-19 who had critical disease and has acceptable safety profile.

Drugs associated with a risk of supraventricular tachycardia: analysis using the OpenVigil database

OBJECTIVE

The OpenVigil database can be used to assess medications that may cause supraventricular tachycardia (SVT) and to produce a reference for their safe use in clinical settings.

METHODS

We analyzed first-quarter data from 2004 to 2023, obtained by searching the OpenVigil database using the keyword "supraventricular tachycardia." Trade names and generic names were obtained by querying the RxNav database, and the proportions were summarized. The proportionate reporting ratio (PRR), reporting odds ratio, and chi-square values were also summarized. We created Asahi diagrams and set the screening criteria to drug events ≥30, PRR >2, and chi-square >4. Outcomes were evaluated using the Side Effect Resource database, several scientific literature databases, and the Hangzhou Yiyao Rational Medication System.

RESULTS

A total of 2435 distinct medications were found to induce SVT between the first quarter of 2004 and 2023, leading to 22,375 documented adverse events related to SVT. Further investigation revealed that salbutamol, paroxetine, formoterol, paclitaxel, venlafaxine, and theophylline were most likely to cause SVT.

CONCLUSION

We conducted signal mining of adverse drug events using the OpenVigil database and evaluated the six drugs most likely to cause SVT. The results of this research can serve as a drug safety reference in the clinic.

Hypertension associated with niraparib in cancer patients: A pharmacovigilance analysis based on the FAERS database and meta-analysis of randomized controlled trials

BACKGROUND

Niraparib plays a crucial role in the treatment of ovarian cancer. A comprehensive understanding of the incidence and risk of hypertension associated with niraparib would be of vital importance to healthcare practitioners.

METHODS

In this study, an observational, retrospective, pharmacovigilance study was conducted based on the FDA Adverse Event Reporting System (FAERS) database. Cases of hypertension related to niraparib were extracted for disproportionality analysis from the first quarter (Q1) of 2017 to Q1 of 2023. Moreover, a separate meta-analysis was performed using the randomized controlled trials (RCTs) on niraparib for cancer treatment published in PubMed, Embase, and Web of Science from inception to May 31st, 2023. The primary outcomes were the incidence and risk of hypertension associated with niraparib.

RESULTS

In the FAERS, 1196 hypertension cases were found to be related to niraparib treatment. Notably, niraparib exhibited the highest level of disproportionality, as indicated by a reporting odds ratio (ROR) of 2.85 (95% CI, 2.69-3.01), suggesting a greater likelihood of causing hypertension compared to other poly-ADP-ribose polymerase (PARP) inhibitors (P < 0.01). Our safety meta-analysis included five pivotal RCTs of niraparib that reported hypertension. In comparison to placebo treatment, the meta-analysis demonstrated a significant increase in the risk of hypertension with niraparib (OR 2.84 [95% CI, 2.17-3.72], P < 0.01), with no heterogeneity observed among the studies (I2 = 0%, χ2 = 2.02, P = 0.73). The incidence of niraparib-induced hypertension was determined to be 16.9% (95% CI, 14.9-18.9; I2 = 34%).

CONCLUSIONS

These findings suggest that hypertension is a distinctive adverse event associated with niraparib compared to other PARP inhibitors. Niraparib significantly increases the risk of hypertension that needs early recognition and management in clinical medication.
