Recurrence of ibuprofen-induced aseptic meningitis in an otherwise healthy patient

Ibuprofen: The Hidden Culprit Behind Aseptic Meningitis

Drug-induced aseptic meningitis represents a significant clinical entity characterized by an inflammatory response of the meninges triggered by specific pharmacological agents. This condition predominantly manifests as a delayed hypersensitivity reaction to a variety of drugs, most notably non-steroidal anti-inflammatory drugs, antibiotics, immune checkpoint inhibitors, and monoclonal antibodies. We report a case of aseptic meningitis in a 54-year-old male presenting with nausea and blurred vision two hours after taking ibuprofen. This case aims to highlight one underrecognized adverse event associated with one of the most commonly used over-the-counter medications worldwide.

Drug-induced meningitis: A review of the literature and comparison with an historical cohort of viral meningitis cases

BACKGROUND

Drug-induced aseptic meningitis (DIAM) is potentially insufficiently considered by clinician, being of rare etiology, with there being no previously published exhaustive study describing its clinical and biological features.

METHODS

Two independent academic clinicians searched all the case reports of DIAM from 1995 until 15^th April, 2017. The search was limited to studies performed in humans, published in English or French. Clinical and biological data of subjects were compared with those of patients with documented viral meningitis.

RESULTS

One hundred and fifty-one case reports fulfilled our inclusion criteria. Non-steroidal anti-inflammatory drugs were the commonest drug cause of AM n=49, followed by antibiotics n=46, biotherapy n=19 and finally immunomodulators n=15. The clinical and biological presentation of DIAM varies according to the causative etiological drug, especially with respect to the interval between exposure and presentation and cerebrospinal fluid (CSF) pleiocytosis. Clinical symptoms associated with meningitis were more prevalent in viral meningitis than in DIAM, except for fever and signs of encephalitis. Cerebrospinal fluid examination in DIAM reveals an increased CSF white cell count and an increased proportion of neutrophils and protein, compared with viral meningitis.

DISCUSSION

We present an extensive review of the DIAM case reports, and highlight their clinical and biological characteristics according to the drugs involved. While comparing for the first time their characteristics with those of viral meningitis, this review hopes in facilitate earlier diagnosis and management of DIAM in clinical practice.

IBUPROFEN-INDUCED ASEPTIC MENINGITIS: A CASE REPORT

ABSTRACT Objective: To report a case of a male adolescent with the diagnosis of ibuprofen-induced meningitis. We discuss themain causes of drug-induced aseptic meningitis (DIAM) and highlight the importance of early recognition of DIAM, sothat the offending drug can be withdrawn, and recurrences prevented. Only few DIAM cases have been reported in pediatric age. Case description: A healthy 15-year-old boy presented to the emergency department with headache, nausea, dizziness, fever, conjunctival hyperemia and blurred vision 30 minutes after ibuprofen-intake. During his stay, he developed emesis and neck stiffness. Cerebrospinal fluid analysis excluded infectious causes, and DIAM was considered. He totally recovered after drug withdrawal. Comments: DIAM is a rare entity, that should be considered in the differential diagnosis of an aseptic meningitis. The major causative agents are nonsteroidal anti-inflammatory drugs, particularly ibuprofen. Suspicion is made by the chronologic link between drug intake and the beginning of symptoms, but infectious causes should always be ruled out.

A rare coexistence: drug induced hepatitis and meningitis in association with Ibuprofen

Ibuprofen, a commonly used NSAID is reported to be associated with drug induced liver injury. Ibuprofen is also known to be associated with drug-induced meningitis especially in patients with connective tissue disorders. However presentation of hepatitis and meningitis in association with Ibuprofen use in the same individual has never been reported. We present a case of young woman who developed abnormal liver chemistries and neurological symptoms while on Ibuprofen. Her liver biopsy findings were suggestive of drug induced liver injury and cerebrospinal fluid analysis was suggestive of aseptic meningitis. Clinical and biochemical improvement was noted on cessation of Ibuprofen.

Mollaret meningitis may be caused by reactivation of latent cerebral toxoplasmosis

Mollaret meningitis (MM) occurs mainly in females and is characterized by recurrent episodes of headache, transient neurological abnormalities, and the cerebrospinal fluid containing mononuclear cells. HSV-2 was usually identified as the causative agent. Recently, we found that recurrent headaches in non-HIV-infected subjects were due to acquired cerebral toxoplasmosis (CT). The aim of the study was therefore to focus on molecular pathomechanisms that may lead to reactivation of latent CT and manifest as MM. Literature data cited in this work were selected to illustrate that various factors may affect latent CNS Toxoplasma gondii infection/inflammation intensity and/or host defense mechanisms, i.e., the production of NO, cytokines, tryptophan degradation by indoleamine 2,3-dioxygenase, mechanisms mediated by an IFN-gamma responsive gene family, limiting the availability of intracellular iron to T. gondii, and production of reactive oxygen/nitrogen species, finally inducing choroid plexitis and/or vasculitis. Examples of triggers revealing MM and accompanying disturbances of IFN-gamma-mediated immune responses that control HSV-2 and T. gondii include: female predominance (female mice are more susceptible to T. gondii infection than males); HSV-2 infection (increased IFN-gamma, IL-12); metaraminol (increased plasma catecholamine levels, changes in cytokine expression favoring T(H)2 cells responses); probably cholesterol contained in debris from ruptured epidermoid cysts (decreased NO; increased TNF-alpha, IL-6, IL-8). These irregularities induced by the triggers may be responsible for reactivation of latent CT and development of MM. Thus, subjects with MM should have test(s) for T. gondii infection performed obligatorily.

Characteristics of meningitis caused by Ibuprofen: report of 2 cases with recurrent episodes and review of the literature

Ibuprofen is a common nonsteroidal antiinflammatory drug that is the most frequent cause of aseptic meningitis induced by drugs. The incidence of this type of aseptic meningitis is increasing, mainly among patients with underlying autoimmune connective tissue disorder, but also among healthy people. We report 2 patients with recurrent meningitis caused by ibuprofen mimicking bacterial meningitis: the first patient a woman with dermatomyositis and the second patient a previously healthy woman who developed autoimmune thyroiditis a few months later. We then review 71 episodes of ibuprofen-related meningitis in 36 patients reported in the literature. Twenty-two patients (61%) presented with an autoimmune connective tissue disorder, mainly systemic lupus erythematosus, and 22 (61%) had recurrent episodes. Most episodes consisted of an acute meningeal syndrome with a predominance of neutrophils in cerebrospinal fluid (CSF) in 72.2% of episodes and elevated protein in the CSF, so the clinical presentation of this type of aseptic meningitis may be quite similar to that of acute bacterial meningitis. CSF glucose levels are usually normal, which may help to differentiate between these 2 types of meningitis. In some cases the clinical presentation is that of meningoencephalitis with neurologic focal deficits. Although based on the close relation between the administration of ibuprofen and the onset of symptoms, especially if previous episodes have occurred, the diagnosis of ibuprofen-induced aseptic meningitis is a diagnosis by exclusion. If the clinical picture is compatible with bacterial meningitis, empirical antibiotic therapy must be administered until negativity of cultures and other microbiologic tests is determined. Rechallenge to ibuprofen reproduces the symptoms and confirms the diagnosis, but is usually not advised. Whatever the clinical presentation, physicians must consider the possibility of ibuprofen-related meningitis or meningoencephalitis in patients taking ibuprofen, especially if they are suffering from an autoimmune connective tissue disorder. On the other hand, we think it would be appropriate to screen for autoimmune disease in previously healthy patients diagnosed with ibuprofen-related meningitis or meningoencephalitis. Finally, we propose that meningitis due to ibuprofen be included in the list of causes of recurrent aseptic meningitis.

Ibuprofen-Associated Aseptic Meningitis

Aseptic meningitis is a rare condition associated with ibuprofen use. It is a diagnosis of exclusion and should be considered only after all infectious and most well-known noninfectious causes have been ruled out. The mechanism of ibuprofen-induced aseptic meningitis is not fully understood; however, most believe it is caused by a hypersensitivity-related reaction. Common symptoms of aseptic meningitis include headache, fever, nuchal rigidity, and confusion. Cerebral spinal fluid analysis generally reveals pleocytosis (the predominant white blood cell varies), with high protein concentrations and normal to low glucose concentrations. Autoimmune diseases and connective tissue diseases may predispose an individual to this condition. It is treated solely by withdrawal of the medication, although supportive treatment is often necessary. It is important that health care practitioners recognize this condition so that they are able to treat and prevent recurrence through patient education.

A child with transient neurologic deficits and headache associated with cerebrospinal fluid pleocytosis

We report a case of a 10-year-old girl who had several episodes of severe headache, altered consciousness, and temporary neurologic signs and symptoms within a 2-month period. Cerebrospinal fluid examination showed lymphocytic pleocytosis and increased protein. Extensive microbiologic investigation and neuroimaging studies were negative. Cerebrospinal fluid findings were normalized within a 3-month period, and the patient has not had further episodes through 15 months of follow-up. This combination of symptoms represents a benign, monophasic illness without further progression. The etiology, however, remains unclear.

Drug-induced aseptic meningitis

Drug-induced aseptic meningitis (DIAM) is an important entity. This article reviews the literature on this rare idiosyncratic event which may occur after local or systemic drug administration. The data on this adverse reaction is predominantly collated from anecdotal case reports and case series.
