Health-Related Quality of Life and Mental Health in Drug Hypersensitivity Reactions and Drug-Induced Anaphylaxis: A Systematic Review and Meta-Analysis

BACKGROUND

Drug hypersensitivity reactions (DHRs) are adverse drug reactions (ADRs) that are particularly impactful on health-related quality of life (HRQoL) and mental health. Although the role of HRQoL as an important patient-reported outcome has been recognized in past years, HRQoL and mental health in patients with ADRs are still poorly investigated.

OBJECTIVE

To evaluate the prevalence, severity, and risk factors of HRQoL and mental health in DHRs, with a particular focus on drug-induced anaphylaxis.

METHODS

We searched the MEDLINE, Scopus, and American Psychological Association PsycArticles databases to identify all studies up to December 31, 2022 that included subjects with at least one episode of DHR and assessments of mental health and/or quality of life. Results were reported as qualitative and quantitative analyses, with meta-analyses after assessment for risk of bias and heterogeneity.

RESULTS

A total of 45 observational studies were included. Overall, a high prevalence of depression (up to 51.4%; odd ratio = 2.94; 95% CI, 1.42-6.10) and anxiety (up to 48%; odd ratio = 3.92; 95% CI, 1.91-8.05) were reported compared with healthy subjects. The HRQoL was significantly affected, especially in the case of drug-induced anaphylaxis (mean score, +5.88; 95% CI, 0.77-10.98).

CONCLUSIONS

Despite the scarce and heterogeneous studies on this topic, the review shows that HRQoL and mental health are markedly affected after ADRs. A better assessment of HRQoL and characterization of patients' mental status may improve the efficacy of therapeutic strategies, which should include psychological support.

Maternal term pruritus and long-term neuropsychiatric hospitalizations of the offspring

PURPOSE

Pruritus during pregnancy is associated with adverse maternal, pregnancy, and neonatal outcomes. We opted to assess the association between term pruritus and long-term neuropsychiatric hospitalizations of the offspring.

METHODS

In a population-based retrospective cohort study, the incidence of long-term neuropsychiatric hospitalizations was compared between offspring born to women with or without pruritus at term. Neuropsychiatric morbidity was assessed up to the age of 18 years according to ICD-9 codes associated with hospitalization of the offspring. A Kaplan-Meier survival curve was used to compare cumulative neuropsychiatric hospitalizations incidence and Cox proportional hazards models were used to control for confounders. The study included 226,918 deliveries of which 600 (0.26%) were in women with term pruritus.

RESULTS

Offspring born to women with pruritus exhibited a higher rate of long-term neuropsychiatric hospitalizations, specifically due to developmental and neurodegenerative disorders. Kaplan-Meier survival curve demonstrated a significantly higher cumulative incidence of long-term neuropsychiatric hospitalizations in offspring of women with pruritus. Using several Cox proportional hazards models, being born to a woman with pruritus was independently associated with an increased risk of long-term neuropsychiatric hospitalizations.

CONCLUSIONS

Maternal term pruritus was found to be independently associated with long-term neuropsychiatric hospitalizations of the offspring.

Perinatal outcome and long-term infectious hospitalizations of offspring born to women with known drug allergy

PROBLEM

Maternal drug allergy has been associated with altered immune status and an inflammatory environment, which may affect the risk of future infectious diseases in the offspring.

OBJECTIVES

We aimed to evaluate perinatal outcomes and long-term infectious hospitalization in the offspring of women with documented drug allergy.

METHOD OF STUDY

The study was conducted at the Soroka University Medical Center, a tertiary medical center. For perinatal outcomes, generalized estimation equation (GEE) models were used controlling for maternal age, maternal diabetes mellitus, smoking, and hypertensive disorders. The study groups were followed until 18 years of age for infectious-related hospitalizations. A Kaplan-Meier survival-curve was used to compare cumulative incidence of long-term infectious hospitalizations. A Cox proportional hazards model was conducted to control for confounders.

RESULTS

During the study period, 243,682 deliveries met the inclusion criteria, of which 9,756 (4.0%) occurred in women with documented drug allergy. Using GEE, maternal drug allergy was found to be a significant independent risk factor for hypertensive disorders, diabetes mellitus, intra-uterine growth restriction (IUGR) and preterm delivery. Offspring also had significantly higher rates of long-term infectious hospitalizations. Kaplan-Meier survival-curves demonstrated significantly higher cumulative incidence rates of infectious hospitalization (log rank p<0. 001). In a Cox proportional hazards model, being born to a mother with documented a drug allergy was independently associated with infectious hospitalization of the offspring in the long-term.

CONCLUSIONS

Maternal documented drug allergy is independently associated with adverse perinatal outcome such as IUGR and preterm delivery and increased risk of long- term infectious hospitalization of the offspring. This article is protected by copyright. All rights reserved.
