New concepts to reduce glucocorticoid toxicity

Addressing Glucocorticoid-Related Problems with the Clinical Pharmacist Collaboration in Rheumatology Practice: A Prospective Follow-Up Study

INTRODUCTION

Glucocorticoids (GCs) play a crucial role in the treatment of many rheumatic diseases regarding their anti-inflammatory and immunosuppressive effects. Inappropriate use of GCs can exacerbate GC-related problems besides complex treatment regimens and miscellaneous well-established adverse events. Although several guidelines exist for managing these problems, there is lack of real-life studies evaluating the problems at the patient level. This study aims to identify GC-related problems among patients with rheumatic diseases and address how they have been solved.

METHODS

This prospective follow-up study was conducted between January 2021 and June 2022 at a university rheumatology outpatient clinic and included patients using GCs. A clinical pharmacist assessed patients for possible GC-related problems at baseline, 3 months, and 6 months. Identified problems, their causes, interventions to address these problems, and their outcomes were categorized using the Pharmaceutical Care Network Europe (PCNE v9.1) classification system. The resolution of the problems was evaluated at the patient's next follow-up visit.

RESULTS

A total of 156 patients were included, and 236 GC-related problems were identified in 66% of the patients. Adverse drug events (possible) accounted for the highest proportion of GC-related problems (94.1%), and the most common causes were lack of laboratory monitoring of GC-related adverse events (41.5%) and lack of drug treatment despite existing indications (39.8%). The median cumulative prednisolone dose was higher in patients with GC-related problems (3115 vs. 5455 mg, p = 0.007). The clinical pharmacist suggested 381 interventions: 47.7% (n = 182) at the 'prescriber level', 31.8% (n = 121) at the 'patient level', and 20.5% (n = 78) at the 'drug level'. Of those interventions, 98% were accepted, and 80.1% of the problems were solved.

CONCLUSIONS

This study showed that the prevalence of GC-related problems is high in patients with rheumatic diseases. Integrating clinical pharmacists into the multidisciplinary rheumatology team provides an advantage in effectively identifying and managing GC-related problems at an early stage.

Side effects of chronic systemic glucocorticoid therapy: what dermatologists should know

In dermatologists' clinical practice, the use of systemic glucocorticoids is recurrent for the management of different comorbidities that require chronic immunosuppression. The prescription of this medication requires caution and basic clinical knowledge due to the several adverse effects inherent to the treatment. However, different doubts may arise or inappropriate conduct may be adopted due to the lack of objective and specific guidelines for the screening, prophylaxis and management of complications from chronic corticosteroid therapy. Considering this problem, the authors carried out a narrative review of the literature to gather up-to-date data on adverse effects secondary to the chronic use of systemic glucocorticoids. The broad approach to this topic made it possible to review the pathophysiology and risk factors for these complications, as well as to develop updated orientation that can be used as a learning tool and quick reference for dermatologists during their clinical practice with glucocorticoids.

Applicability of glucocorticoid toxicity index in pemphigus: Comparison between two groups of rituximab-treated and rituximab-naïve patients

Rituximab (RTX) combined with short-term glucocorticoids (GC) is an effective therapeutic option for pemphigus. The newly developed Glucocorticoid Toxicity Index (GTI) tool provides the possibility to measure GC toxicities over time. To compare 1-year GTI between two groups of RTX-treated and RTX-naïve patients with pemphigus. The responsiveness of the GTI was also investigated. A prospective cohort of 129 adults with newly diagnosed pemphigus was conducted. GC-related toxicities were assessed at 3-month intervals according to Composite and Specific lists of the GTI. Of the patients, 76.7% (n = 99) received RTX. Throughout the time intervals, RTX-treated patients had lower GTI compared to RTX-naïve ones (p = 0.036). The mean GTI at 1-year was 34.3 in the RTX-treated group and 50.8 in the RTX-naïve group (p = 0.04). The most commonly observed GC-related toxicity was neuropsychiatric manifestations for 34% (224 events). The relapse rate of RTX-treated patients (1%) was significantly lower than RTX-naïve patients (10%) (p = 0.037). The GTI showed no correlation with cumulative GC consumption in both groups (p > 0.05, both). Patients treated with GC alone had remarkably higher GTI than patients treated with GC plus RTX. The GTI is an applicable tool to quantitatively capture GC toxicities at the patient level in pemphigus.

The safety of glucocorticoids in the treatment of inflammatory rheumatic disease: new evidence

PURPOSE OF REVIEW

Glucocorticoids justifiably remain a cornerstone in the treatment of many inflammatory rheumatic diseases but many are opposed to their use because of the side effects, most of them known to be dose-dependent. Most concerns regarding glucocorticoids stem from observational studies which are affected by several forms of bias, mainly confounding by indication, that may result in overestimation of harm. Solid evidence regarding the safety of low-dose glucocorticoids remains remarkably scarce.

RECENT FINDINGS

Several observational studies showed heterogeneous results and two 6-month trials showed no increase of harm. The GLORIA trial of 5 mg/day prednisolone vs. placebo in patients aged 65+ is the first randomized control trial with glucocorticoids safety as coprimary outcome. The benefits of glucocorticoids in terms of symptoms and structural damage were confirmed, but the proportion of patients with at least one adverse event of special interest (serious or glucocorticoids-related) was increased by 24%, mostly due to nonsevere infections.

SUMMARY

Based on current evidence the benefit-risk balance of low-dose glucocorticoids in rheumatoid arthritis, and probably in other rheumatic diseases is generally favourable. Physicians should be aware of the risks and mitigate them, but avoid the negative effects of unfounded fear.

Effect of IV Acetaminophen Usage on Opioid Requirements, Outcomes and Costs of Care for Postoperative Children in a Pediatric Intensive Care Unit

OBJECTIVE

Children admitted to the ICU are commonly treated with opioids for postoperative pain. We hypothesized that administration of IV acetaminophen in the immediate postoperative period is effective in lowering cumulative opioid use leading to other benefits.

METHODS

This was a retrospective chart review of patients admitted to the PICU between December 2016 and April 2019. For each patient, data including demographics, cumulative opioid usage per kilogram, oral or rectal acetaminophen, x-ray findings, hospital costs, and surgical procedure were collected. Cumulative opioid usage was determined by converting all opioids to morphine equivalents (MEs) per kg. Standard descriptive and comparative analyses were conducted using SAS 9.4 (SAS Institute, Inc, Cary, NC).

RESULTS

A total of 200 patients met inclusion and exclusion criteria (N = 92 in IV acetaminophen group and N = 108 in no IV acetaminophen group). There was no significant difference in ME per kilogram between the groups (0.3 ME/kg in IV acetaminophen group, IQR 0.5 ME/kg versus 0.4 ME/kg in no IV acetaminophen group, IQR 0.5 ME/kg, adjusted p = 0.38). Rate of atelectasis was not significant between the groups (47.8% in IV acetaminophen versus 45.4% in no acetaminophen group, p = 0.28). There was a significant difference in median total hospital costs between the groups ($22,456 in IV acetaminophen group, IQR $18,650 versus $18,552 in no IV acetaminophen group, IQR $13,361, adjusted p = 0.04).

CONCLUSIONS

IV acetaminophen in the immediate postoperative period did not lead to a decrease in cumulative opioid usage or rate of atelectasis. IV acetaminophen usage was associated with increase in overall hospital costs per patient.
