This study examined the relationship between levels of vitamin D and autoantibodies in people with lupus.
The researchers hoped to learn about whether a protein in the blood called C4d could serve as an indicator of lupus nephritis activity in people with lupus.
As people with lupus have become increasingly educated about their disease and involved in their medical care, input from patients about their condition has become increasingly important and useful. Recently, the Lupus Damage Index Questionnaire (LDIQ) was developed for this purpose and captures the spectrum of knowledge acquired from the SDI in a patient-reported questionnaire.
The researchers hoped to learn about the effects of lupus and/or its treatments on multiple indicators or growth and development in children.
The researchers hoped to learn about the relationship between the presence of specific lupus susceptibility genes and the development of specific disease manifestations.
The researchers hoped to learn the prevalence of self-reported photosensitivity among people with lupus, as well as its effects on quality of life.
The researchers aimed to estimate the risk of breast, endometrial, and ovarian cancers in women with lupus relative to that for the general population.
The researchers aimed to determine the effects of the ISN-RPS re-classifications for lupus nephritis on patient outcomes.
