Rheumatic fever is a multisystem inflammatory disease that occurs as a delayed sequel to group A streptococcal pharyngitis. It is less common than it was 50 years ago but is still a major cause of heart disease in developing areas of the world. The relationship between the site of infection, the type of causative organism, and susceptibility of the host is essential in the development of the disease. Its major clinical manifestations include carditis, migratory polyarthritis, chorea, erythema marginatum, and subcutaneous nodules. It can manifest as an acute febrile illness consisting of migratory polyarthritis involving the large joints, as carditis and valvulitis, or as Sydenham's chorea with involvement of the central nervous system. The disorder in its milder form resolves itself without sequelae. Carditis is the condition most associated with increased mortality and morbidity and may be fatal in its severe forms. Penicillin is the most appropriate primary and secondary prophylaxis. Anti- inflammatory agents provide symptomatic relief but do not prevent rheumatic heart disease.

Accelerated vascular calcification is a well-described complication of chronic kidney disease often affecting large and small vessels alike through a variety of mechanisms. Accordingly, dysregulation of calcium and phosphate balance, vitamin D metabolism, hyperparathyroidism, and endothelial injury can lead to both macrovascular and microvascular complications. We describe a 56-year-old Hispanic male with a history of end-stage renal disease, diabetes mellitus type 2, and medical noncompliance who developed sequential digital ischemia and necrosis involving both hands as well as right foot as a result of Mönckeberg sclerosis. An extensive metabolic and serologic workup was unrevealing but radiographic studies and histopathology revealed the diagnosis. A multifaceted approach was instituted including wound debridement and amputations along with intensive medical support. In addition to improving hypertensive control and striving for improved calcium and phosphate balance, sodium thiosulfate solution was administered for more than 1 year. This aggressive approach allowed his wounds to heal and has arrested further digital ischemia from occurring.
