Nephrogenic Fibrosing Dermopathy/Nephrogenic Systemic Fibrosis in 2 Patients With End-Stage Renal Disease on Hemodialysis

Nephrogenic fibrosing dermopathy/nephrogenic systemic fibrosis (NFD/NSF) is a newly recognized disorder occurring in patients with renal failure. It is manifested by progressive cutaneous and systemic fibrosis involving the extremities and the trunk with usual sparing of the face and internal organs. NFD/NSF can lead to joint contractures and painful disability. The etiology is unknown and there are no proven effective treatments. NFD/NSF must be distinguished from other clinically similar disorders such as scleroderma, scleromyxedema, and eosinophilic fasciitis among a myriad of others. NFD/NSF can pose many diagnostic challenges to physicians; however, a team of experienced rheumatologists, nephrologists, dermatologists, and dermatopathologists is essential in identifying this disorder. We report 2 new cases of NFD/NSF in patients on hemodialysis.

Flare of arthritis with successful treatment of Felty's syndrome with granulocyte colony stimulating factor (GCSF)

A 58-year-old white male with Felty's syndrome was successfully treated with granulocyte colony stimulating factor (GCSF). GCSF can correct the granulocytopenia of Felty's syndrome and may be a beneficial therapeutic adjunct in patients who have serious infections associated with neutropenia. The patient developed a flare of arthritis concomitant with increased circulating neutrophils following GCSF therapy.
