Despite evidence of associations between glucocorticoid treatment and adverse psychiatric and suicidal behaviour outcomes, large-scale observational evidence for serious outcomes is lacking.
Aims
To assess the risk of psychiatric and suicidal behaviour outcomes during glucocorticoid treatment.
Method
Using Swedish population registers, we identified 1 105 964 individuals aged 15–54 years who collected a glucocorticoid prescription in oral form between 2006 and 2020. We investigated associations with a range of psychiatric outcomes: unplanned specialist healthcare contacts due to depressive, bipolar, anxiety or schizophrenia-spectrum disorders; and deaths by suicide or unplanned specialist healthcare contacts due to self-harm (‘suicidal behaviour’). We estimated hazard ratios from Cox proportional hazards models in a medication-only cohort by comparing outcome rates during and outside treated periods within individuals. We further identified individuals with an autoimmune or gastrointestinal autoimmune disorder diagnosis and compared hazards of the outcomes between those who did and did not initiate a glucocorticoid using a target trial emulation approach.
Results
We found increased risks for psychiatric outcomes, with within-individual hazard ratios ranging from 1.08 (95% CI, 1.00–1.16) for depressive disorders to 1.23 (95% CI, 1.12–1.36) for bipolar disorder and 1.25 (95% CI, 1.20–1.31) for anxiety disorders. We found no clear association with suicidal behaviour (hazard ratio: 1.06; 95% CI, 0.96–1.17). These findings were similar when stratified by age and gender. Within-individual associations were attenuated in those diagnosed with an autoimmune disorder. The risk of anxiety and bipolar disorder outcomes appeared particularly elevated in the first weeks of treatment. Absolute rates were modestly elevated during treatment, and higher in those with a history of psychiatric disorders.
Conclusions
Glucocorticoid treatment is associated with elevated risks of serious psychiatric outcomes, including the onset and relapse of common psychiatric disorders. Individuals with psychiatric histories may require additional monitoring during glucocorticoid treatment.
The aim of this study was to assess the extent to which three non-invasive measures of welfare in laying hens (egg-shell quality, corticosteroid levels as measured from the birds' faeces, and behavioural preferences) were correlated over a period of five days in two groups of birds. One group had access to an enriched test area (bark chips on the floor and a tray of sprouted wheat); the other group had access to a comparably sized barren area (bare wire mesh floor). The measure of preference used was the amount of time hens spent in the test area as measured each day. It was predicted that birds with access to the less preferred environment would show higher levels of faecal corticosteroids and egg-shell anomalies. However, although the birds showed a preference for the enriched environment from Day 1, the other two measures did not follow the same pattern. Faecal corticosteroid metabolites showed an initial increase in both groups, which declined significantly by Day 4, with the ‘enriched’ birds in fact showing a trend for higher levels than the ‘barren’ birds. Shell thickness also showed a change over the five days, but with a different time course: declining to a minimal level on Day 3 and then rising again by Day 5. No measure of shell quality was significantly different between the two environments, but there was a trend for changes in shell thickness to be more pronounced in eggs from enriched birds. The results indicate the caution that needs to be exercised in using shell quality or corticosteroid measurements in isolation from assessments of what the animals themselves prefer.
Behavioural and salivary Cortisol responses were measured in hamadryas baboons (Papio hamadryas) (n = 5) undergoing positive reinforcement training (PRT). Compliance was assessed by collecting behavioural data on desirable and undesirable responses during each training session (33-46 training sessions per male). Saliva was collected before implementation of the training programme (3-4 baseline samples per male) and immediately before and ten minutes after a training session (24-53 saliva samples per male). During training, the incidence of leaving the training area, vocalising and threat displays changed across time. Performance of the desired behaviour (holding a target for increasing increments of time) improved for all males during the study period. Concentrations of salivary cortisol were similar for pre-training and post-training collection times, but both were significantly lower than baseline concentrations. The overall decline in undesirable behaviours and the absence of constantly elevated salivary cortisol suggest that PRT had no adverse effects on animal welfare.
Cross-institutional studies that combine non-invasive physiological measures of stress responses and the assessment of individual differences in behaviour and temperament have great potential as tools for assessing the well-being of zoo animals and for identifying key environmental stimuli relevant to well-being. In addition, such studies allow comparison of animals under a wide variety of conditions and enable researchers to obtain sufficiently large samples sizes for statistical data analyses. Faecal corticoid measurements, a method recently developed to monitor adrenal activity in wildlife and domestic species, can be obtained non-invasively as part of the normal husbandry routine. While basic techniques still need improvement, and interpretation of the acquired measures can be challenging, assessment of faecal corticoid concentrations can provide a useful indicator of stress responses under a variety of captive conditions. Here we report on three studies that illustrate this approach and the results that can be obtained. An on-going study reveals significant differences in the pattern of variability of faecal corticoid concentrations between polar bears that are reported by keepers to perform stereotypic behaviour and those that do not. In another study, faecal corticoid measures indicated that stress responses to certain extraneous noises might interfere with the breeding of Hawaiian honeycreepers in captivity. In a study of clouded leopards, higher faecal corticoid concentrations were measured when cats were kept on public display or near potential predators compared to individuals maintained off exhibit or in the absence of visible predators. The findings of an on-going experimental study suggest a causal relationship between the provision of additional hiding spaces and a decline in faecal corticoid concentrations in clouded leopards.
Implantation is a complex biological process and for the maternal tolerance of an antigenically different fetus, controlled inflammation and activation of immune response in the peri-implantation period is essential. Elevated follicular cortisol:cortisone ratio is associated with good follicular development, oocyte maturation and successful implantation. However, as the follicles are unable to biosynthesise cortisol, corticosteroid therapy has been tested and shown to improve clinical pregnancy in women having stimulated IVF/ICSI cycles. Corticosteroid gradient at the feto-maternal interface is essential and is facilitated by progesterone induced 11βHSD-I activity. In women with recurrent miscarriage, expression of 11βHSD-I in decidualising endometrium is blunted by high uterine natural killer (uNK) cell density, which also has a negative impact on decidualisation marker genes and endometrial cytokines, suggesting that local steroid deficiency leads to impaired decidualisation. Prednisolone has been shown to reduce uNK cell density and although a pilot RCT suggested possible clinical benefit, validation from larger trials is awaited.
Corticosteroids may induce psychiatric symptoms (agitation, fear, hypomania, insomnia, irritability, labile mood, pressured speech and restlessness) with incidence rates ranging from 1,8% to 57%. We present a case of corticosteroid-induced mania and psychosis.
Objectives
Non-systematic review on corticosteroid therapy induced psychiatric symptoms. Analysis and comparison of a patient’s case with the existing literature.
Methods
Case report and a non-systematic review through databases as Pubmed, UpToDate, Medscape, between 2000 and 2020.
Results
We present a female 70 year-old patient without psychiatric background, diagnosed with Rhizomelic Pseudopolyarthritis, who started treatment with prednisone 20 mg. During the third month of treatment the patient started progressively worse behavior changes (such as destruction of the neighbor’s property), developed persecutory delusions, decreased sleep and increased energy. The patient was committed to our psychiatric ward and started on diazepam 10 mg and olanzapine 15 mg per day. Despite introduction of antipsychotics, which has evidence for mood stabilization, the patient maintained the symptoms, so it was necessary to gradually reduce corticosteroids until symptomatic control.
Conclusions
Psychosis (24%), hypomania and mania (35%), are the most common psychiatric reactions to corticosteroid therapy. Several studies show that even a low dosage may induce psychiatric disturbances, most frequently during the first two weeks of treatment. However, as reported in this case, symptoms may occur at any time. Thus, a multidisciplinary team, as well as training of professionals from different specialties, such as psychiatry, rheumatology and endocrinology, are needed, since these syndromes may be confused with pure psychiatric conditions and consequently delay treatment and compromise prognosis.
Coronavirus disease 2019 was first seen in December 2019. Due to the insidious and complex nature of the disease, the list of symptoms is rapidly expanding. So far, few studies have reported sudden sensorineural hearing loss as a possible symptom of coronavirus disease 2019.
Case report
A 60-year-old woman with a complaint of sudden sensorineural hearing loss and subjective severe tinnitus presented to the ENT clinic. Coronavirus disease 2019 was subsequently confirmed with a polymerase chain reaction test. At the time of presentation, she was treated with intra-tympanic dexamethasone. Improvements in hearing threshold and speech perception, and a subjective reduction in tinnitus, were observed after treatment.
Conclusion
This case report supports evidence from other case reports of a possible association between coronavirus disease 2019 and sudden sensorineural hearing loss. Sudden sensorineural hearing loss may be a symptom of this disease that behaves as an underlying aggravating factor. Intra-tympanic injection of corticosteroids is recommended for managing these patients during the pandemic.
Steroids have been shown to be beneficial in patients and mice with eosinophilic meningitis caused by Angiostrongylus cantonensis infection; however, the mechanism for this beneficial effect is unknown. We speculated that the effect of steroids in eosinophilic meningitis caused by A. cantonensis infection may be mediated by the downregulation of matrix metallopeptidase-9 (MMP-9) and oxidative stress pathways via glucocorticoid receptors (GRs). We found blood–brain barrier (BBB) dysfunction in mice with eosinophilic meningitis 2–3 weeks after infection as evidenced by increased extravasation of Evans blue and cerebrospinal fluid (CSF) albumin levels. The administration of dexamethasone significantly decreased the amount of Evans blue and CSF albumin. The effect of dexamethasone was mediated by GRs and heat shock protein 70, resulting in subsequent decreases in the expressions of nuclear factor kappa B (NF-κB), c-Jun N-terminal kinase (JNK), and extracellular signal-regulated kinase (ERK) in the CSF and brain parenchymal after 2 weeks of steroid administration. Steroid treatment also decreased CSF/brain homogenate MMP-9 concentrations, but had no effect on CSF MMP-2 levels, indicating that MMP-9 rather than MMP-2 played a major role in BBB dysfunction in mice with eosinophilic meningitis. The concentration of 8-hydroxy-2'-deoxyguanosine (8-OHdG) gradually increased after 1–3 weeks of infection, and the administration of dexamethasone significantly downregulated the concentration of oxidized derivative 8-OHdG in CSF. In conclusion, increased 8-OHdG and MMP-9 concentrations were found in mice with eosinophilic meningitis caused by A. cantonensis infection. The effect of dexamethasone was mediated by GRs and significantly decreased not only the levels of 8-OHdG and MMP-9 but also NF-κB, JNK and ERK.
Converting from one steroid to another is often necessary and can cause much head scratching. However, help is at hand with this chapter detailing common conversions, and some basic rules on managing and withdrawing steroid therapy.
More closely analogous to the use of combination therapies in multiple sclerosis (MS) is the use of combination therapies in autoimmune diseases such as rheumatoid arthritis. In the case of MS, drugs could be directed at different therapeutic domains such as tissue destruction and tissue repair. Currently, natalizumab is approved only as a monotherapy. This is due to concern over combined toxicity because of the two cases of progressive multifocal leukoencephalopathy (PML) that occurred in patients enrolled in the combination arm of the SENTINEL trial. Perhaps the most frequently used combination therapy approach utilized in clinical practice for patients with relapsing-remitting MS and continued disease activity while on platform therapy is the ad hoc addition of periodic courses of corticosteroids, most often intravenous methylprednisolone. This chapter discusses cytotoxic therapies and combination trials with other immunomodulating agents such as daclizumab, terilunomide and statins.
Neuromuscular diseases include disorders of anterior horn cells, anterior and posterior roots, plexus, peripheral nerves, neuromuscular junctions, and muscles. Detailed history and physical examination most often provide reliable information to localize the neuromuscular disorder. Motor neuron diseases have in common the dysfunction of the superior or inferior motor neuron. Immune myasthenia gravis is caused by autoantibodies interfering with the normal neuromuscular transmission. Most myopathies are slowly progressing diseases involving predominantly proximal muscles. Corticosteroids are the first-line immunosuppressive treatment in most chronic immune-mediated neuromuscular diseases. Neurological disorders may cause respiratory failure by impairing pulmonary ventilation. For normal ventilation to occur, multiple central and peripheral nervous system structures need to be intact. Respiratory management of neuromuscular respiratory failure requires differentiating between slowly developing conditions in which respiratory failure occurs as an exacerbation of a chronic condition, and rapidly progressive diseases.
The inflammatory response is a central component of sepsis as it drives the physiological alterations that are recognized as systemic inflammatory response syndrome (SIRS). In contrast to the hypothesis of exuberant inflammatory response in sepsis is the finding that septic patients may have a relative anti-inflammatory environment. Cellular death may be a key factor in sepsis and its related mortality. Cells that are destined to die can do so by two mechanisms: apoptosis and necrosis. In sepsis, cytokine-induced coagulopathy triggers increased activity of tissue factor (TF) and plasminogen activator inhibitor-1 (PAI-1) and decreased levels of the natural anticoagulant protein C on mononuclear and endothelial cells. Critical illness related corticosteroid insufficiency (CIRCI) occurs as a result of either a decrease in adrenal steroid production. In patients with severe sepsis, a strategy of glycaemic control using intravenous insulin should include a nutritional protocol with preferential use of the enteral route.
The diagnosis of neuropathic pain (NP) encompasses a broad array of conditions. For the acute care provider, the goals of NP therapy are to decrease persistent pain and suppress breakthrough pain. One recommended strategy for NP treatment is to begin the therapy simultaneously with two drugs: an analgesic (e.g. mild opioid) and an adjuvant (e.g. antidepressant). Opioid doses in NP may be relatively higher than customary for non-NP indications, and in fact varying types of NP may warrant different opioid dosages. Clinically, patients with allodynia are potential candidates for local anesthetic use. Local anesthetics may also be useful in NP when administered in the form of regional nerve blocks. Since inflammatory mediators sensitize nociception, the anti-inflammatory corticosteroids have been used for NP. Corticosteroids also decrease local edema, thus reducing pressure on peripheral nerves. As dexamethasone has relative few mineralocorticoid effects, it is preferred by many who use corticosteroids in NP.
This chapter focuses on sore throat caused by viral or bacterial infection. It assumes that clinicians exercise appropriate precautions about airway management and possible complicating diagnoses. The NSAIDs, most commonly ibuprofen, are usually recommended for pain treatment of mild-to-moderate viral or bacterial pharyngitis (PG) in both adults and children. Aspirin, commonly dosed at 400-800 mg orally, is an effective PG pain reliever and is associated with symptomatic improvement. Acetaminophen is an effective reliever of mild pain, providing better PG relief than placebo within as little as 15 minutes. Corticosteroids, administered IM or PO in single or multiple doses, hasten the onset of both partial and complete pain relief in adults. In children, the utility of dexamethasone probably mirrors that of use of corticosteroids in adults with PG. Benzocaine (delivered by lozenges or spray) is commonly used for PG pain, but there are little applicable data for this indication.
To investigate the prevalence in adults of pharyngeal and laryngeal symptoms associated with the use of inhaled corticosteroids.
Design:
Prospective, observational and based on a structured, specifically designed postal questionnaire.
Setting:
University Hospital Aintree, Liverpool, UK.
Participants:
The questionnaire was distributed to 190 patients on the basis of current inhaled corticosteroid use. Recruitment was from the databases of two local general practices. Individuals were classified as mild, moderate or severe asthmatics, using the guidelines of the British Thoracic Society.
Main outcome measures:
Demographic data, including smoking history, were recorded. The number, type, strength, dosing regime and duration of individual inhaler use were recorded. Specific pharyngeal and laryngeal side effects were enquired about. Co-morbidities and preventive measures were also recorded. Results were analysed using univariate and multivariate statistical tests.
Results:
There was a 75.8 per cent response rate (144/190 questionnaires); 63 (43.8 per cent) of respondents were male and 81 (56.2 per cent) were female. The majority of our patients were either mild or moderate asthmatics. Longer use of an inhaled corticosteroid predisposed to weak voice (p = 0.0016), hoarseness (p = 0.0001) and throat irritation (p = 0.008). Hoarseness, throat irritation, sore throat and cough were observed much more frequently than anticipated. Severe asthmatics were more likely to use a spacer device compliantly (p = 0.0487; odds ratio 1.53). Side effects were more prevalent as asthma severity worsened (p = 0.0049; odds ratio 1.87).
Conclusions:
Inhaled corticosteroids cause sore throats, throat irritation, hoarseness and cough. Further research in this area is required in order to elucidate the mechanism of inflammation. Only then can effective preventive measures be introduced and implemented.
Corticosteroid excess is associated with impairment in declarative memory and hippocampal changes. in animals, phenytoin blocks the effects of stress on memory and hippocampal histology. Levetiracetam also shows neuroprotective properties in some animal models. This report examines whether levetiracetam prevents mood or cognitive changes secondary to prescription corticosteroids.
Materials and methods
Thirty outpatients given systemic corticosteroid therapy for asthma were randomized to either levetiracetam (1500 mg/day) or placebo given concurrently with the corticosteroids. Mood was assessed with the Hamilton rating scale for depression (HRSD), Young mania rating scale (YMRS) and activation (ACT) subscale of the internal state scale, declarative memory with the Rey auditory verbal learning test (RAVLT), and attention and executive functioning with the Stroop color and word test at baseline and after approximately 7 days of corticosteroid plus levetiracetam or placebo therapy.
Results
Levetiracetam and placebo groups showed significant improvement from baseline to exit on RAVLT total words recalled with a non-significant change on other outcomes. No significant between-group differences were found. initial prednisone dose showed a significant correlation with change in some cognitive domains.
Conclusions
Levetiracetam was well tolerated when combined with prednisone. Significant between-group differences in mood and cognition were not found.
