Bone pain after transplantation is a frequent complication that can be caused by several diseases. Treatment strategies depend on the correct diagnosis of the pain. Nine patients with severe pain in their feet, which was registered after transplantation, were investigated. Bone scans showed an increased tracer uptake of the foot bones. Magnetic resonance imaging demonstrated bone marrow oedema in the painful bones. Pain was not explained by other diseases causing foot pain, like reflex sympathetic dystrophy, polyneuropathy, Morton's neuralgia, gout, osteoporosis, avascular necrosis, intermittent claudication, orthopaedic foot deformities, stress fractures, and hyperparathyroidism. The reduction of cyclosporine- or tacrolimus trough levels and the administration of calcium channel blockers led to relief of pain. The Calcineurin-inhibitor Induced Pain Syndrome (CIPS) is a rare but severe side effect of cyclosporine or tacrolimus and is accurately diagnosed by its typical presentation, magnetic resonance imaging and bone scans. Incorrect diagnosis of the syndrome will lead to a significant reduction of life quality in patients suffering from CIPS.
HCV infection after transplantation is associated with a high mortality whereas chronic HCV infection before trans plantation does not have a significant impact on mortality. Patients with replicating HBV infection or concomitant HBV and HCV infection have a high risk of graft loss and mortality.
BACKGROUNDOne of the common late sequela in patients with end-stage renal disease (ESRD) is the calcium phosphate disorder leading to chronic hypercalcemia and hyperphosphatemia causing the precipitation of calcium salt in soft tissues. Tumoral calcinosis is an extremely rare clinical manifestation of cyst-like soft tissue deposits in different periarticular regions in patients with ESRD and is characterized by extensive calcium salt containing space-consuming painful lesions. The treatment of ESRD patients with tumoral calcinosis manifestation involves an increase in or switching of renal replacement therapy regimes and the adjustment of oral medication with the goal of improved hypercalcemia and hyperphosphatemia.CASE SUMMARYWe describe a 40-year-old woman with ESRD secondary to IgA-nephritis and severe bilateral manifestation of tumoral calcinosis associated with hypercalcemia, hyperphosphatemia and tertiary hyperparathyroidism. The patient was on continuous ambulatory peritoneal dialysis and treatment with vitamin D analogues. After switching her to a daily hemodialysis schedule and adjusting the medical treatment, the patient experienced a significant dissolution of her soft tissue calcifications within a couple of weeks. Complete remission was achieved 11 mo after the initial diagnosis.CONCLUSIONReduced patient compliance and subsequent insufficiency of dialysis regime quality contribute to the aggravation of calcium phosphate disorder in a patient with ESRD leading to the manifestation of tumoral calcinosis. However, the improvement of the treatment strategy and reinforcement of patient compliance enabled complete remission of this rare disease entity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
