PRES occurs in young lupus patients and in the early part of the disease. Focal deficits are not uncommon. It can be the presenting manifestation of lupus. Management is predominantly symptomatic. Immunosuppression is directed by other major organ manifestations. Early diagnosis and appropriate management is productive.

Infections, renal failure and cardiovascular disease account for the majority of mortality in systemic lupus erythematosus (SLE). Although most infections are caused by Gram-positive or Gram-negative bacteria, there is an increase in the incidence of Mycobacterium tuberculosis and other opportunistic infections that also account for increased mortality. The higher prevalence of tuberculous infections in SLE is attributed to multiple immune abnormalities seen in these patients. SLE and tuberculosis (TB) interact in complicated ways - they may have similar presentation and may mimic each other. In an individual patient, it becomes important to differentiate one from the other. In this review, we have highlighted the complex interactions of these diseases, the impact of one on the other and the various modalities available for the evaluation and management and their shortcomings. Considering the high prevalence of TB in India, it becomes all the more important for us to be aware of this interaction in our population.
