Antithrombotic activity, necessary doses and effects on coagulation and lipid variables of the low molecular weight heparin derivative Fragmin were compared to unfractionated (UF) heparin in long-term multicentre trials. Results of more than 10,000 dialyses are reported. On the basis of preliminary studies, UF heparin and Fragmin doses were used that lead to anti-Xa activities of more than 0.5 U/ml. With this dose, sufficient antithrombotic activity was achieved with both heparins. Bleeding complications were not noticed. Partial thromboplastin time (PTT) and thrombin time were only marginally increased by Fragmin (5-8 s) in contrast to UF heparin (PTT 90-120 s, thrombin time 230-260 s). Surprisingly, the elevated levels of factor VIII strongly decreased during the 6-month treatment period with Fragmin and increased again during the following 6-month treatment period with UF heparin. Creatinine, urea, haemoglobin and transaminases did not change in both heparin groups: this excluded reduced dialysis efficiency or occult blood loss. Additionally, 15 patients with acute renal failure and high bleeding risk were dialysed with low doses of Fragmin (anti-FXa: 0.2-0.3 U/ml). No severe bleeding occurred. A continuous ambulant peritoneal dialysis patient with deep vein thrombosis was treated effectively with intraperitoneal application of Fragmin for 6 months without any problems.

The prevalence of venous thromboembolism (VTE) in cancer patients has been estimated as up to 15% antemortem, and higher (over 50% in pancreatic tumours) postmortem owing to the asymptomatic nature of many episodes of VTE. We investigated the prevalence of deep venous thrombosis (DVT) in a population of 298 hospice inpatients with advanced cancer. They were screened for the presence of DVT using light reflection rheography; 258 (86.6%) patients were evaluable for DVT, which was found in 135 (52%; 95% confidence interval 46-58). Factors associated (multivariate analysis) with the presence of DVT were: poor mobility, reduced serum albumin level and higher serum urea. A DVT risk assessment index was calculated using these variables. The three highest categories all had significant rates of DVT and, although the lowest category had a low rate of DVT, it accounted for less than 10% of all patients tested. DVT is common in patients with advanced cancer. It was found to be significantly associated with the above variables, but a combined index was of limited clinical application. In view of the number of patients identified with DVT, repeated small pulmonary emboli may be responsible for more symptoms than previously recognized in cancer patients.

Congenital insensitivity to pain with anhidrosis (CIPA) is an autosomal recessive disorder caused by mutations in the neurotrophic tyrosine receptor kinase 1 (NTRK1) gene which encodes the receptor for nerve growth factor (NGF). We report the clinical course in three sibs with CIPA and proven NTRK1 gene mutations with a follow-up over a 25-year period in one of them. They had the characteristic clinical features of an abnormally high pain threshold, and mental retardation; in addition their clinical course was marked by the occurrence of early onset renal disease with recurrent microhematuria and proteinuria and frequent observations of increased serum creatinine and blood urea levels. Light microscopy study of a renal biopsy performed in one of them at age of 20 months showed focal glomerulosclerosis, interstitial fibrosis and tubular atrophy. This patient and his younger brother died because of renal failure at the age of 25 years and 14 years, respectively. The sister still alive showed renal impairment and deep venous thrombosis associated with lupus anticoagulant activity, decrease of circulating autoreactive CD5 (+) B lymphocytes and increased urinary levels of IgG and kappa and lambda light chains, suggesting a possible defect in regulation of B-lymphocyte function. In the light of the NGF-related molecular defect, the extraneurological tissue involvement in CIPA might in part reflect dysregulation of immune mechanisms which possibly brings about a chronic inflammatory response. This, in turn, could result in renal disease which should be mentioned among the life-threatening complications associated with this disorder.

We report the case of an 87-year-old white woman with myasthenia gravis who presented with nausea, shortness of breath, azotemia, and hyperkalemia shortly after completing a course of intravenous immunoglobulin (IVIG). She had been receiving monthly transfusions of IVIG, but this time had received daily infusions for 5 days rather than 1 day. She had received this same dose in the past without incident. Her history was significant for coronary artery disease, atrial fibrillation, deep venous thrombosis, pulmonary embolism, chronic steroid use, and recurrent urinary tract infection. On examination, she was slightly confused, mildly dehydrated, had a grade II systolic ejection murmur along the upper left sternal border, had bilateral and symmetric mild weakness of the upper and lower extremities, and exhibited mild edema of the lower extremities. Before transfer from the emergency room, she was found to have an elevated serum urea nitrogen and creatinine of 55 and 5.8 mg/dL (19.6 mmol/L and 512.7 micromol/L, respectively). Creatinine 8 days earlier was 0.9 mg/dL (79.6 micromol/L). The hospital course of the acute renal failure is presented with a review of the literature on cases of acute renal failure after IVIG.
