The aims of this study are to investigate the cytokine, chemokine and adhesion molecule profiles in cerebrospinal fluid from patients with neuropsychiatric systemic lupus erythematosus and systemic lupus erythematosus with central nervous system infection. Experimental sets were established which included 108 patients and 132 cerebrospinal fluid samples. The patients were grouped as neuropsychiatric systemic lupus erythematosus (n = 54), systemic lupus erythematosus with central nervous system infection (n = 16), systemic lupus erythematosus controls (n=20), and non-inflammatory neurological disease (n=18). The dynamic changes of 21 patients in the neuropsychiatric systemic lupus erythematosus group before and after induction therapy were further analyzed. IL-1 beta, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17, TNFalpha, IFN gamma, IP-10, MCP-1, RANTES, VCAM-1, and P-selectin were measured in cerebrospinal fluid samples by using a fluorescent bead-based assay. Cerebrospinal fluid levels of IL-8, MCP-1, P-selectin and VCAM-1 were significantly increased in neuropsychiatric systemic lupus erythematosus compared with systemic lupus erythematosus controls. IL-6, IL-17, IL-8 and VCAM-1 were higher in systemic lupus erythematosus with central nervous system infection than in systemic lupus erythematosus controls. Among systemic lupus erythematosus with central nervous system infection, the IL-6, IL-17, IL-8 and IP-10 levels were higher than those in neuropsychiatric systemic lupus erythematosus. After sufficient induction therapy, IL-8, MCP-1, P-selectin, VCAM-1 and IL-6 in patients with neuropsychiatric systemic lupus erythematosus decreased significantly. Levels of all molecules tested in non-inflammatory central nervous system disease were not different from those of systemic lupus erythematosus controls. From our data, the intrathecal cytokine/chemokine profile is different among patients with neuropsychiatric systemic lupus erythematosus, systemic lupus erythematosus complicated with central nervous system infection and systemic lupus erythematosus controls. IL-8, MCP-1, VCAM-1, P-selectin and IL-6 in cerebrospinal fluid are effective parameters to monitor neuropsychiatric systemic lupus erythematosus disease activity and response to treatment. Significantly elevated IL-17, IL-6, and to a lesser extent, IL-8, favors central nervous system infection in systemic lupus erythematosus.

Progressive multifocal leukoencephalopathy (PML) is a subacute central nervous system infection due to reactivation of the JC virus. Most reported cases occurred in HIV-infected patients (80% of cases), patients with lymphoid malignancies (13%) and transplant recipients taking immunosuppressants (5%). Less often, PML has been described in patients with chronic inflammatory joint diseases associated with autoimmune disorders (lupus, rheumatoid arthritis [RA] and vasculitis) (2%). Magnetic resonance imaging of the brain shows suggestive changes and confirmation of the diagnosis is obtained by performing PCR tests to identify the JC virus in the cerebrospinal fluid or, when necessary, a brain biopsy. No treatments have been proven effective. Most patients experience progressive disease that is fatal within a few months or induces incapacitating neurological impairments. The risk of PML is 0.4/100,000 in patients with RA. In the few case-reports of PML in RA patients, the treatments used included methotrexate (five cases) combined with a biological agent such as infliximab (one case), rituximab (four cases), or leflunomide (two cases including one with concomitant rituximab). PML is an extremely rare but devastating complication. Rituximab therapy is associated with an increased prevalence of PML in RA patients (4/100,000), who should be informed of this risk. In patients with lupus, the risk of PML is higher than in RA (4/100,000) and 40% of cases of PML occur during low-dose glucocorticoid therapy without immunosuppressive therapy.

To investigate the cytokine profile in serum and cerebrospinal fluid (CSF) from patients with systemic lupus erythematosus (SLE) and central nervous system infection, we measured interferon-g (IFN-g), interleukin-1b (IL-1b), IL-4, IL-6, IL-8, IL-10, and IL-17 levels in serum and CSF from 50 SLE patients and 38 matched controls. In patients with active compared to quiescent disease, serum levels were higher for IL-1b (P = 0.042) and IL-17 (P = 0.041) but we found no significant correlation between IL-1b and IL-17 and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) (r = 0.055, r = 0.219, respectively). IL-10 level in active patients was lower compared to that in quiescent controls (P = 0.032). When comparing specific disease manifestations, IL-1b levels in patients with fever (P = 0.035) and IL-6 (P = 0.048) and IL-8 (P = 0.048) levels in those showing nervous system involvement were higher than in controls. Based on MRI results, we found that only increased cerebral ischemia was associated with increased IFN-g levels (P = 0.009). In neuropsychiatric lupus erythematous patients, CSF levels of IL-6 (P = 0.002), IL-8 (P = 0.009), and IL-17 (P = 0.034) were significantly higher when compared with control patients. IL-10:IL-1b ratio in patients with moderate and quiescent disease was higher than in patients with disease activity (P = 0.000). Pro-inflammatory adaptive cytokines were elevated during disease flare, while regulatory mediators were elevated during periods of stable disease. Alterations in the balance between inflammatory and regulatory mediators may be targets for novel immunotherapeutic agents for managing autoimmune diseases.

We report a case of a new diagnosis of systemic lupus erythematosus (SLE) in a patient with HIV who presented to the outpatient department with a fever, headache and lymphadenopathy. Cerebrospinal fluid analysis showed lymphocytic pleocytosis. Initial concerns were for an infectious process, and investigations for systemic and central nervous system infection were negative. Serum testing for ANA, dsDNA, nucleosome, anti-histone and ribosomal-P antibodies was positive. A magnetic brain imaging scan of the brain showed a well-circumscribed lesion in the right cerebellar peduncle on T2/FLAIR. The patient was commenced on prednisolone and rituximab, and had a good clinical response. The cerebellar lesion resolved and has not recurred with sequential imaging. SLE and HIV are both multi-systemic diseases which rarely co-occur. Autoimmune processes should be considered in HIV patients with multi-systemic symptoms and signs.
