Obsessive-Compulsive Symptoms as a Manifestation of Neuropsychiatric Systemic Lupus Erythematosus

Neuropsychiatric involvement in systemic lupus erythematosus: A case series

Patients with systemic lupus erythematous that suffers from one or more of several neuropsychiatric symptoms represent a subcategory termed "neuropsychiatric systemic lupus erythematosus" (NPSLE). Different environmental factors, such as infection, stress, and ischemia, mediated by inflammatory cytokines, may damage the blood-brain barrier, further contributing to neuropsychiatric symptoms. Antiribosomal-P antibodies are specifically related to psychosis in NPSLE. Three patients of systemic lupus erythematosus who developed features of psychosis are presented and the condition is briefly discussed.

The Psychopharmacology of Obsessive-Compulsive Disorder: A Preclinical Roadmap

This review evaluates current knowledge about obsessive-compulsive disorder (OCD), with the goal of providing a roadmap for future directions in research on the psychopharmacology of the disorder. It first addresses issues in the description and diagnosis of OCD, including the structure, measurement, and appropriate description of the disorder and issues of differential diagnosis. Current pharmacotherapies for OCD are then reviewed, including monotherapy with serotonin reuptake inhibitors and augmentation with antipsychotic medication and with psychologic treatment. Neuromodulatory therapies for OCD are also described, including psychosurgery, deep brain stimulation, and noninvasive brain stimulation. Psychotherapies for OCD are then reviewed, focusing on behavior therapy, including exposure and response prevention and cognitive therapy, and the efficacy of these interventions is discussed, touching on issues such as the timing of sessions, the adjunctive role of pharmacotherapy, and the underlying mechanisms. Next, current research on the neurobiology of OCD is examined, including work probing the role of various neurotransmitters and other endogenous processes and etiology as clues to the neurobiological fault that may underlie OCD. A new perspective on preclinical research is advanced, using the Research Domain Criteria to propose an adaptationist viewpoint that regards OCD as the dysfunction of a normal motivational system. A systems-design approach introduces the security motivation system (SMS) theory of OCD as a framework for research. Finally, a new perspective on psychopharmacological research for OCD is advanced, exploring three approaches: boosting infrastructure facilities of the brain, facilitating psychotherapeutic relearning, and targeting specific pathways of the SMS network to fix deficient SMS shut-down processes. SIGNIFICANCE STATEMENT: A significant proportion of patients with obsessive-compulsive disorder (OCD) do not achieve remission with current treatments, indicating the need for innovations in psychopharmacology for the disorder. OCD may be conceptualized as the dysfunction of a normal, special motivation system that evolved to manage the prospect of potential danger. This perspective, together with a wide-ranging review of the literature, suggests novel directions for psychopharmacological research, including boosting support systems of the brain, facilitating relearning that occurs in psychotherapy, and targeting specific pathways in the brain that provide deficient stopping processes in OCD.

A case of neuropsychiatric lupus Erythematosus characterized by the Owl's eye sign: a case report

Background

Systemic lupus erythematosus (SLE) is an autoimmune inflammatory disorder characterized by multiple affected systems. More than half of SLE patients will suffer from neuropsychiatric lupus erythematosus (NPSLE) during the course of their disease. Although nearly half of the NPSLE patients have normal MRI manifestations, the abnormalities found in the remainder can be located anywhere in the brain, and especially in the subcortical white matter of the frontal and temporal lobe. However, NPSLE involving the medulla oblongata and spinal cord which presents as the “owl’s eye” sign has to our best knowledge not been reported to date.

Case presentation

A 19-year-old girl presented at our hospital with a 7-day history of fever and headache since a one day’s exertion, accompanied by 2 days of weakness. The patient had slurred speech. Neurological examination revealed the presence of horizontal nystagmus and a limitation of bilateral eye movement when looking up and down. At the same time, she showed difficulty in raising the jaw, accompanied by a weak pharyngeal reflex. Muscle strength was remarkably decreased in all four extremities: the MRCS grade of the upper limbs was 4/5, while in the lower limbs it was 0/5. Hypotonia was apparent in the lower extremities. Regarding subjective sensation, the patient appeared to be experiencing an increased sense of pain in the whole body, and especially in the cervical region, abdomen, and feet. An examination of shallow reflex documented the reinforcement of the abdominal reflex. Deep tendon reflexes were symmetric: absent in lower, normal in upper extremities. The patient also had a stiff neck with a positive Kernig’s sign. The laboratory examination showed elevated C - reactive protein and rheumatoid factor, as well as complement components 3 and 4. Symptomatic treatments were applied, but she did not respond well, after which we did immunological laboratory examinations. The results showed the presence of anti-nRNP/Sm, anti-dsDNA and anti-AMA M2 antibodies. An MRI scan and enhancement of the cervical and thoracic regions displayed abnormal signs in the medulla and bilateral anterior horn of the lower thoracic spine. Following the exclusion of other possible diseases, neuropsychiatric lupus was diagnosed. High-dose intravenous gamma-globulin combined with methylprednisolone gradually improved her condition.

Conclusion

We report the first case of NPSLE presenting with medulla oblongata and spinal cord involvement, manifesting as the “owl’s eye” sign in MRI.

Executive dysfunction, obsessive-compulsive symptoms, and attention deficit and hyperactivity disorder in Systemic Lupus Erythematosus: Evidence for basal ganglia dysfunction?

INTRODUCTION

Chorea is well described in a group of patients with Systemic Lupus Erythematosus (SLE). There is less information, however, on other movement disorders as well as non-motor neuropsychiatric features such as obsessive-compulsive symptoms (OCS), executive dysfunction and attention deficit and hyperactivity disorder (ADHD) in subjects with SLE.

METHODS

Fifty-four subjects with SLE underwent a battery of neuropsychiatric tests that included the Mini Mental State Examination, the Montreal Cognitive Assessment, the Frontal Assessment Battery (FAB), the FAS verbal and the categorical (animals) semantic fluency tests, the Obsessive and Compulsive Inventory - Revised, the Yale-Brown Obsessive and Compulsive Scale and Beck's Anxiety and Depression Scales. ADHD was diagnosed according to DSM-IV criteria. SLE disease activity and cumulative damage were evaluated according to the modified SLE Disease Activity Index 2000 (mSLEDAI-2K) and the SLICC/ACR, respectively.

RESULTS

Six (11.1%) and 33 (61.1%) patients had cognitive impairment according to the MMSE and MoCA, respectively. Eleven (20.4%) had abnormal FAB scores, and 5 (9.3%) had lower semantic fluency scores than expected. The overall frequency of cognitive dysfunction was 72.2% (39 patients) and of neuropsychiatric SLE was 77.8% (42 patients). Two patients (3.7%) had movement disorders. Fifteen (27.8%) had OCS and 17 (31.5%) met diagnostic criteria for ADHD. ADHD and OCS correlated with higher disease activity, p=0.003 and 0.006, respectively. Higher cumulative damage correlated with lower FAB scores (p 0.026).

CONCLUSIONS

Executive dysfunction, ADHD, OCS, and movement disorders are common in SLE. Our finding suggests that there is frequent basal ganglia dysfunction in SLE.
