Nephrogenic systemic fibrosis typically occurs in patients with renal failure and is strongly associated with gadolinium exposure through stimulation of macrophage-activated fibrosis. Patients present with prominent fibrosis of the skin and internal organs. Quality of life is significantly diminished due to impairment from restrictive mobility of large and small joint contractures, pain, and ensuing psychological stress. Nephrogenic systemic fibrosis can be severe and life-threatening. Nephrogenic systemic fibrosis patients reliant on hemodialysis with cutaneous symptoms, defined as hyperpigmentation, hardening, and tethering of skin on the extremities, experience rates of mortality as high as 48%. Physician awareness and preventive strategies coincided with a reduction in the incidence of nephrogenic systemic fibrosis. Several treatments, of which physical therapy may be a key adjuvant, have been used to treat nephrogenic systemic fibrosis, with variable and inconsistent results, lacking wide consensus. Improvement of renal function may improve nephrogenic systemic fibrosis, with some patients demonstrating stabilization or improvement after renal transplantation or resolution of acute renal failure. Imatinib, a tyrosine kinase inhibitor, demonstrates antifibrotic effects in the skin and recently was used to successfully treat nephrogenic systemic fibrosis. We report a case of severe nephrogenic systemic fibrosis with extensive skin fibrosis causing extrapulmonary restriction who demonstrated improved lung function following treatment with imatinib. |
