Neuropsychiatric Lupus and The Curious Case of Molly – What Does This Case Teach Us? – Prof Hughes
Prof Graham Hughes introduces Molly, a 14-year-old girl from Ireland. She had a butterfly rash, hair loss, DNA binding (Anti- DNA antibodies), low C3 but no renal disease. She did not respond to steroid treatment and azathioprine but when Pulse cyclophosphamide 500mgs was administered as treatment, she had clear cerebral improvement and at 2-year follow-up had clinical and serological improvement.
What is this 14-year-old girl telling us? What is her long term prognosis? She is now 44 and a Professor of History Cambridge.
What is this patient teaching us? –
We don’t know how common CNS involvement is in lupus and this is where the fiction comes in. There are so many different figures.
According to Estes & Christian (1971), cerebral involvement occurs in up to 60% of SLE patients.
The Study by Jarpa et al., (2011) found that:
Psychiatric diagnoses occurred in 44.6% of patients; the most frequent was major depressive episode (21.7%). No association with lupus activity was observed in patients with a DSM-IV diagnosis or MDE or psychological suffering. ACR 1999 NPSLE criteria were present in 42.2% of patients, the majority corresponding to mood (28.9%) or anxiety disorders (15.6%). Suicidal risk was present in 9.6% of patients. Anti-ribosomal P antibodies (13.3%) were not associated with DSM-IV diagnosis.
They concluded –
Severe psychiatric disorders in SLE are common and not associated with disease activity.
According to Calderon –
Depression has only a marginal contribution to cognitive impairment in SLE, suggesting that different pathogenic mechanisms drive this Neuropsychiatric manifestation in this autoimmune disease.
Other neurological features have also been described such as a decreased sense of smell. The ACR has classified Neuropsychiatric Lupus into 19 syndromes.
