'Steroid psychosis': a case report

Systemic Absorption and Side Effects of Locally Injected Glucocorticoids

Local glucocorticoid injections are often used to treat joint, soft tissue, or spinal pain, but the systemic side effects associated with these injections are poorly understood and not well recognized. There are significant known risks to systemic administration of glucocorticoids. However, there are no guidelines that address issues of systemic absorption, overall systemic risks, or other side effects of locally injected glucocorticoids. For this review, a literature search was performed, and the available evidence on systemic absorption and clinical side effects of intra-articular and epidural glucocorticoids was synthesized. The goal was to improve clinical understanding of risks associated with these injections. Existing data suggest there is significant individual variability in the amount of systemic absorption and clinical effects of locally injected glucocorticoids. However, it is clear that both intra-articular and epidural injections can have systemic effects for weeks and that complications may be associated with their use, including Cushing syndrome, loss of bone density, infection, and hyperglycemia. The concurrent use of oral steroids, the number of injections, and the type and dose of glucocorticoids used all are important considerations in estimating risks. The total dose calculation of cumulative glucocorticoid exposure should include all local injections. Caution should be exercised when local glucocorticoid injections are used in higher risk patients, such as postmenopausal women, people with diabetes, and those considering surgery in the near term. Better provider awareness of possible systemic risks should improve decision making and informed consent with patients when considering intra-articular and epidural steroid injections for painful conditions. LEVEL OF EVIDENCE: IV.

Psychosis in Systemic Lupus Erythematosus: Results From an International Inception Cohort Study

Objective

To determine, in a large, multiethnic/multiracial, prospective inception cohort of patients with systemic lupus erythematosus (SLE), the frequency, attribution, clinical, and autoantibody associations with lupus psychosis and the short‐ and long‐term outcomes as assessed by physicians and patients.

Methods

Patients were evaluated annually for 19 neuropsychiatric (NP) events including psychosis. Scores on the Systemic Lupus Erythematosus Disease Activity Index 2000, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, and the Short Form 36 (SF‐36) were recorded. Time to event and linear regressions were used as appropriate.

Results

Of 1,826 SLE patients, 88.8% were female and 48.8% were Caucasian. The mean ± SD age was 35.1 ± 13.3 years, the mean ± SD disease duration was 5.6 ± 4.2 months, and the mean ± SD follow‐up period was 7.4 ± 4.5 years. There were 31 psychotic events in 28 of 1,826 patients (1.53%), and most patients had a single event (26 of 28 [93%]). In the majority of patients (20 of 25 [80%]) and events (28 of 31 [90%]), psychosis was attributed to SLE, usually either in the year prior to or within 3 years of SLE diagnosis. Positive associations (hazard ratios [HRs] and 95% confidence intervals [95% CIs]) with lupus psychosis were previous SLE NP events (HR 3.59 [95% CI 1.16–11.14]), male sex (HR 3.0 [95% CI 1.20–7.50]), younger age at SLE diagnosis (per 10 years) (HR 1.45 [95% CI 1.01–2.07]), and African ancestry (HR 4.59 [95% CI 1.79–11.76]). By physician assessment, most psychotic events resolved by the second annual visit following onset, in parallel with an improvement in patient‐reported SF‐36 summary and subscale scores.

Conclusion

Psychosis is an infrequent manifestation of NPSLE. Generally, it occurs early after SLE onset and has a significant negative impact on health status. As determined by patient and physician report, the short‐ and long‐term outlooks are good for most patients, although careful follow‐up is required.

Steroid psychosis: a review for neurosurgeons

Steroids are beneficial in neurological illness, but have many serious side effects. Having observed several patients with severe steroid psychoses, which greatly prolonged their hospitalizations, the authors sought to improve understanding of this entity. A literature review was conducted. The incidence of severe psychiatric symptoms was estimated in a meta-analysis of 2,555 patients to be 5.7 % and the incidence of any psychiatric symptoms was 18.6 % in patients receiving >80 mg/day of prednisone (12 mg/day dexamethasone). Dose is not predictive of time of onset, severity, type, or duration of symptoms. Symptoms can develop rapidly following exposure to even low doses and with oral, epidural, or intra-articular administration. Glucocorticoid effects on the brain fall into three categories: genomic, non-genomic, and neurotrophic/neurotoxic and can be permanent. Excessive glucocorticoid exposure may result in decreased production of endogenous neurosteroid molecules, resulting in unopposed glucocorticoid effects. Treatment includes early recognition, steroid withdrawal when appropriate, reduction in stimulation, and medication. Atypical antipsychotics like olanzapine and risperidone may cause fewer dystonic reactions and extrapyramidal symptoms than typical antipsychotics like haloperidol, and therefore, are often recommended as first line treatment. Steroids are powerful medications with many undesirable side effects. They should be used with caution. More research is needed on their effects on the human central nervous system.

Central nervous system effects of natural and synthetic glucocorticoids

Natural glucocorticoids (NGC) physiologically modulate body homeostasis and coordinate adaptive responses to stress, involving almost all organs and tissues, including brain. Since their therapeutic availability, synthetic GC (SGC) have been successfully prescribed for a variety of diseases. Mounting evidence, however, demonstrated pleiotropic adverse effects (AE), including central nervous system (CNS) disturbances, which are often misdiagnosed or underestimated. The aim of the present study was therefore to review and discuss the CNS effects of both NGC and SGC. A detailed search was carried out of the available literature using the PubMed (US National Library of Medicine) database. Cortisolemia plays a crucial role in control of behavior, cognition, mood, and early life programming of stress reactivity. Hypercortisolemia or SGC treatments may induce behavioral, psychic and cognitive disturbances, due to functional and, over time, structural alterations in specific brain target areas. These AE are generally dose and time dependent (infrequent at prednisone-equivalent doses <20 mg/day) and usually reversible. Pediatric patients are particularly susceptible. Behavioral changes, including feeding and sleeping modifications, are common. Psychic AE are unpredictable and heterogeneous, usually mild/moderate, severe in 5-10% of cases. Manic symptoms have been mostly associated with short SGC courses, and depressive disorder with long-term treatments. Suicidality has been reported. Cognitive AE peculiarly affect declarative memory performance. Physiologic levels of NGC are essential for efficient brain functions. Otherwise, hypercortisolemia and SGC treatments may cause dose-/time-dependent neuropsychic AE and, over time, structural alterations in brain target areas. Clinicians should carefully monitor patients, especially children and/or when administering high doses SGC.

Systemic effects of intra-articular corticosteroids

The objective of this study was to review all the published articles in the English literature about the systemic effects of intra-articular corticosteroid injection (IACI) in humans. Reports were searched through Pubmed using the terms intraarticular or intra-articular and steroids, corticosteroids, or glucocorticosteroids up and including the year 2007. Reports were also located through references of articles. Only objective findings outside the injected joint were included. The overwhelming majority of the studies was done at the knee joint and in rheumatoid arthritis/juvenile idiopathic arthritis patients. Many of the studies were done on the hypothalamic-pituitary-adrenal axis. Serum cortisol decreased within hours with a nadir after usually 24-48 h following the IACI. Recovery to baseline takes 1-4 weeks and sometimes longer depending on the type and dose of IACI and on the number of injected joints. Serum cortisol levels were blunted following adrenocorticotropic hormone stimulation in a small proportion of patients following methylprednisolone acetate injection and more common following other preparations. IACI resulted in a transient increase in blood glucose levels over few days in controlled diabetic patients with knee osteoarthritis. Peak levels are around 300 mg%. IACIs are associated with reduction in inflammatory markers like C-reactive protein and erythrocyte sedimentation rate that start few days following the IACI and could last for months. The effect on inflammatory cytokines is immediate with significant decrease within hours. IACI may induce remission also in patients with oligo-/polyarthritis and/or in patients with extra-articular manifestations. Other metabolic, hematologic, vascular, allergic, visual, psychologic, and other effects were also reported.

Steroid psychosis: a review

This review is built upon a time-framed perspective to unfold the growth of evidence and the shifting of focus from primary affective short-term reactions to later findings of cognitive deficits and possible permanent impairment linked to steroid treatment. An incidence related to dosage has been documented and delirium and withdrawal symptoms have been reported in later studies. A hypothesis of sensitization process with multiple course of steroids has been proposed with the reporting of recurrent cases. The issue of individual risk appears unsettled while management of psychiatric reactions to steroids has shifted toward prophylactic use of lithium.

Mood and Cognitive Changes During Systemic Corticosteroid Therapy

BACKGROUND: Physicians in the United States write approximately 10 million new prescriptions for oral corticosteroids each year. Common side effects of corticosteroids include weight gain, osteoporosis, and diabetes mellitus. This article reviews the available literature on psychiatric and cognitive changes during corticosteroid therapy. METHOD: A search of the MEDLINE and psycINFO databases was conducted to find clinically relevant articles on psychiatric and cognitive side effects with corticosteroids using search terms including corticosteroid, prednisone, mania, depression, psychosis, mood, memory, and cognition. RESULTS: Symptoms of hypomania, mania, depression, and psychosis occur during corticosteroid therapy as do cognitive changes, particularly deficits in verbal or declarative memory. Psychiatric symptoms appear to be dose-dependent and generally occur during the first few weeks of therapy. Patients who must remain on corticosteroids may benefit from pharmacotherapeutic approaches, such as lithium and the new antipsychotic medications. CONCLUSION: Mood and cognitive changes with corticosteroids appear to be common but generally mild and reversible side effects. More studies are needed to determine effective treatment for steroid-induced psychiatric disorders.

Corticosteroid-induced adverse psychiatric effects: incidence, diagnosis and management

Reports of corticosteroid-induced adverse psychiatric effects began to appear in the literature soon after the introduction of these medications in the 1950s. Unfortunately, early studies relied on informal classification and measurement procedures and tended to utilise nonspecific descriptive terminology (such as steroid psychosis'). A growing number of contemporary investigations have begun to address these problems. However, the literature remains surprisingly undeveloped from a pharmacoepidemiological perspective, consisting largely of case reports and case series. The objective of this review is to summarise published data concerning corticosteroid-induced adverse psychiatric effects. A clinical perspective will be adopted since opportunities to minimise the impact of corticosteroid-induced adverse effects tend to present themselves most readily within the sphere of clinical management. Some of the psychiatric adverse effects of corticosteroids are mild, and not necessarily clinically significant. However, several serious psychiatric syndromes can be caused by corticosteroids: substance-induced mood disorders (with depressive, manic and mixed features), substance-induced psychotic disorders and delirium. While certain clinical groups may be at greater risk of corticosteroid-induced adverse psychiatric effects, corticosteroid-induced psychiatric toxicity is remarkably unpredictable. The literature regarding prevention and treatment of corticosteroid-induced adverse psychiatric effects is poorly developed. As a result, the emphasis of this review is on clinical and epidemiological evidence linking specific adverse effects to corticosteroid medications. However, clinical reports do provide some practical guidance for prevention and treatment, and these are summarised as well. A variety of pharmacological strategies for treatment and prevention have been proposed. Education and support also appear to be important, and perhaps neglected.

The psychiatric side effects of corticosteroids

LEARNING OBJECTIVES

Readers will learn the importance of psychiatric symptomatology with corticosteroid drug therapy, especially when combined with other medications.

DATA SOURCES

A brief history of corticosteroid use over the last five decades was complied utilizing MEDLINE and PSYCHOINFO as sources of information which include peer-reviewed research articles, case studies, and relevant reviews in English.

CONCLUSION

Corticosteroids are routinely prescribed for a variety of allergic and immunologic illnesses. Psychiatric side effects from corticosteroids include mania, depression and mood disturbances. Psychiatric symptoms usually occur within the first two weeks of corticosteroid therapy and seem to be dose related. Treatment with lithium or antipsychotics may be helpful. Physicians should carefully monitor patients for psychiatric and cognitive side effects of corticosteroid use.

Prednisone mood disorder with associated catatonia

Since steroid-induced psychoses often appear as mood disorders and since catatonia may be associated with psychotic mood disorders, the possibility exists for a steroid-induced psychotic mood disorder to present with associated catatonia. In a computer review of the medical literature, however, I found no such cases in adult patients. This report is presented as a possible case of steroid-induced catatonia in a 62-year-old woman following treatment with melphalan, prednisone, and cimetidine for multiple myeloma of the IgA class with associated mild hypercalcemia.

Corticosteroids in cancer: neuropsychiatric complications

The addition of corticosteroids in the early 1950s to the treatment armamentarium provided cure of some diseases and control of many. They have become an integral part of many cancer treatment regimens. Early reports of severe affective disorders appear less frequent today in patients receiving steroids, though controlled studies are rare. Minor mood changes are common, ranging from the euphoria of initial treatment to depressive symptoms on withdrawal. The most common severe disturbances seen clinically in cancer patients are the organic mood disorders and delirium. Studies are needed, especially in cancer, which control for prior psychiatric history, cancer site, cancer treatment, pain regimen, coexisting cancer complications, especially central nervous system complications, and physical performance status. DSM-III-R terminology must be used as the diagnostic classification for reliable investigation. A more careful clinical delineation of the mental changes with steroids is desirable not only for the clinical relevance, but for the potential understanding of the etiology of mood disorders and mental changes seen in delirium.

Prednisolone psychosis: clinical observations

Corticosteroid-induced acute psychoses in three Chinese patients receiving prednisolone 15-75 mg/d are described. The cases are compared with other cases of corticosteroid mental disturbances in the literature. It is concluded that the mental disturbance usually occurs within the first ten days of treatment, and presents most often in women, as either an acute manic or depressive episode accompanied by delusion and/or hallucinations. An exponential increase in the risk of the mental disturbance occurs as the corticosteroid dose increases.

Steroid-induced psychiatric syndromes. A report of 14 cases and a review of the literature

Although it is well-established that psychiatric symptoms can develop in association with the administration of corticosteroids, the nature of this relationship is poorly understood. We reviewed 14 previously unreported cases of steroid-induced psychiatric syndromes, 79 cases from the literature and 29 studies of the clinical efficacy of steroids in various medical illnesses. Our findings indicate that severe psychiatric reactions occur in approximately 5% of steroid-treated patients, and that a large proportion of these patients have affective and/or psychotic symptoms. Psychiatric disturbances usually occur early in the course of steroid therapy. Female sex, systemic lupus erythematosus and high doses of prednisone may be risk factors for the development of a steroid-induced psychiatric syndrome. Treatment with steroid-taper, neuroleptics or electroconvulsive therapy is generally effective, although tricyclic antidepressants do not appear to be useful therapeutic agents. Most patients recover within several weeks of the onset of symptoms.

Genetic disorders presenting as "schizophrenia". Karl Bonhoeffer's early view of the psychoses in the light of medical genetics

There is overwhelming empirical evidence for the influence of genetic factors in the etiology of schizophrenic psychoses. An appreciable and still increasing number of exogenous factors have been known for decades that are capable of inducing psychoses that present as "schizophrenia" or are more or less similar to it. In this article, genetic disorders--chromosomal abnormalities and Mendelian diseases--are summarized that may be associated with such psychoses. These disorders frequently but not necessarily exhibit additional physical symptoms. Although the majority of schizophrenic psychoses can so far not be explained by exogenous factors or well-defined genetic disorders, the proportion of these etiologies among all cases may be higher than presumed so far, because they evade detection. Data from the literature are discussed in the light of Karl Bonhoeffer's early concept of exogenous reaction types and modern medical genetics.

Adverse psychiatric reactions to modern medication

From this survey it will be apparent that many psychiatric reactions to drugs are largely caused by their direct toxic actions or from combinations of drugs. As such, they are often dose related, although age and slow speed of detoxification will increase the risk of patients developing delirium, hallucinations, sleep disturbances, anxiety etc. Similar toxic reactions can also occur when drugs to which a patient has developed some measure of tolerance are abruptly withdrawn. In this context the effects of drugs upon patterns of sleep may be important determinants of adverse withdrawal symptoms. In contrast are the reactions which resemble one or other of the functional psychoses. In these patients it appears that a past history of an affective or schizophrenic psychosis is the best predictor of a similar illness being precipitated by a particular drug. Nonetheless, with substances like reserpine and cycloserine there is good reason for thinking that, given a sufficient quantity, practically any patient can develop an adverse psychiatric reaction.

Psychological effects caused by drugs in overdose

Drug overdose is a common occurrence which accounts for up to 25% of medical inpatient admissions. Intentional overdose or attempted suicide is the most common cause of overdose, but there are other types of overdose which are often unrecognised as are the effects caused by these overdoses. Iatrogenic overdose occurs frequently and is often unavoidable. Many patients will make mistakes with their treatment and unwittingly suffer from the toxic effects of the drugs they are taking. About 7% of intentional overdose patients who are admitted to hospital have taken the drug for some psychological effect they have been seeking and have taken too much. This group is described as those who take 'drugs for kicks'. As many of the drugs taken cross the blood-brain barrier and exert some toxic effect on the cerebral cortex, secondary psychological disturbances frequently occur in all of these groups of patients, and can sometimes be the only sign of dangerous toxicity. It is important to recognise the patient's gross disturbances of behaviour, thinking and perception as a manifestation of drug toxicity which can be life threatening and often requires intense medical treatment. The range of the psychological response is somewhat limited and there is not a specific psychological disturbance characteristic of the toxicity of each group of drugs. However, there are some reactions which, coupled with the physical symptoms shown by the patient, can help to identify the patient as suffering from the toxic effects of drugs and even give some indication as to the type of drugs taken. This article describes the various psychiatric syndromes caused by drugs in overdose and attempts to identify these with most of the commonly encountered groups of drugs.
