Demyelinating syndrome in systemic sclerosis and neuromyelitis optica.

BACKGROUND

This article reports a case diagnosis of a 44-year-old female who presented with intractable hiccups and vomit complicated with an acute onset of paraplegia. Transverse myelitis was evident on MRI and serological studies were consistent with Neuromyelitis Optica (NMO) based on NMO-IgG sero-positivity. Further studies revealed positive ANA, anti-RNA polymerase III autoantibodies, and Scl-70, leading to a concurrent diagnosis of systemic sclerosis (SSc). The coexistence of these two disease processes and their underlying clinical manifestations and therapeutic interventions are seldom reported in literature and are worth reporting.

CASE PRESENTATION

The patient was treated with high dose steroids, and subsequently developed malignant hypertension and acute renal failure, later identified on biopsy as steroids-induced scleroderma renal crisis. Although Neuromyelitis Optica spectrum disorder (NMOSD) has often been associated with various collagen and autoimmune diseases, the coexistence of NMOSD and SSc presented a challenge where the patient underwent aggressive physical therapy and necessitated an intervention with Rituximab to achieve an appropriate clinical response. We have received a written consent forms from the participant in our study, and we have them on file in case they are requested. We have also received the patient's written consent for the data and images presented in this article.

CONCLUSION

This article expands on NMOSD associated autoimmune diseases. Systemic Sclerosis is an insidious disease that is often diagnosed late as not all patients often report skin manifestation. The finding suggests that patients presenting with acute neurological manifestations get tested for NMO-IgG/AQP-4 antibodies and other immunological studies based on clinical findings.
