Hi Had reviewed her history. This is called as juvenile SLE; This is basically an autoimmune disease , where body’s own immunity is acting against self and trying to harm the body more. This could be due to underlying genetic changes and associated triggers like sunlight and other environmental factors. According to your history, there appears to be no major kidney involvement. Proteinuria can be estimated again using 24 hour urinary protein( to collect urine for 24 hours and check protein content). If it is more than 500 mg/ 24 hours then we consider a kidney biopsy and assess the amount of damage. In case there is no proteinuria of > 500 or no albumin in the urine, we usually just monitor. Definitely she has skin involvement, she strictly needs to avoid sunlight which is the most important protective measure to prevent / control flares. Unfortunately, there is no cure but definitely disease can be very well controlled.
