Antiphospholipid antibodies: anticardiolipin and the lupus anticoagulant in systemic lupus erythematosus (SLE) and in non-SLE disorders. Prevalence and clinical significance.

PURPOSE - To determine the prevalence of lupus anticoagulant and anticardiolipin in systemic lupus erythematosus (SLE) and in non-SLE disorders, and to evaluate the clinical significance of these autoantibodies as they relate to thromboembolic events, neuropsychiatric disorders, thrombocytopenia, and fetal loss.
DATA IDENTIFICATION - A computer-assisted search of the literature (MEDLINE, 1966 to 1989) and review of the bibliographies of all identified articles.
STUDY SELECTION - Series of ten or more subjects were included if the assays used for detecting lupus anticoagulant or anticardiolipin met the specified minimal criteria for validity.
DATA EXTRACTION - Series were categorized according to antibody type and underlying disease. A systematic appraisal of patient selection methods, study design, and assay methods was done.
RESULTS OF DATA ANALYSIS - An analysis of 29 published series (comprising over 1000 patients with SLE) yielded an average frequency of 34% for the lupus anticoagulant and 44% for anticardiolipin. Antiphospholipid antibodies are also prevalent in patients with various non-SLE disorders. In patients with SLE, a statistically significant association exists between the presence of either antibody and a history of thrombosis, neurologic disorders, or thrombocytopenia. The available data suggest, but do not firmly support, an association between antiphospholipid antibodies and history of fetal loss in women with SLE. Contrary to prevailing opinion, none of these associations have been shown conclusively in patients with non-SLE disorders.
CONCLUSIONS - The results of predominantly retrospective series suggest that for certain persons (patients with SLE or closely related disorders) antiphospholipid antibodies may be important risk factors for thrombosis, neurologic disease, thrombocytopenia, and fetal loss. Standardized tests for lupus anticoagulant and anticardiolipin, as well as long-term, prospective clinical studies, are needed to determine the prognostic value of antiphospholipid antibodies.

Vascular trauma as a result of therapeutic procedures for the treatment of malignancy.
Myers SI, Harward TR, Putnam JB, Frazier OH
(1991) J Vasc Surg 14: 314-9
MeSH Terms: Adolescent, Adult, Aged, Aneurysm, Antineoplastic Agents, Arteries, Blood Vessel Prosthesis, Catheters, Indwelling, Female, Follow-Up Studies, Hemorrhage, Humans, Iatrogenic Disease, Infusions, Intra-Arterial, Ischemia, Leg, Male, Middle Aged, Neoplasm Invasiveness, Neoplasm Metastasis, Neoplasms, Retrospective Studies, Thromboembolism, Vascular Diseases
Show Abstract · Added March 27, 2014
Twenty-two iatrogenic vascular injuries caused by resection of tumors with local recurrences or adjuvant chemotherapy were treated over a 42-month period in 11 female and 8 male patients with cancer (58% had documented metastases). Sixteen of 22 vascular injuries were caused by intraarterial administration of chemotherapy (8 emboli; 8 direct catheter trauma), and six were caused by resection of tumors with local invasion. The injuries were extremity ischemia (15 extremities in 13 patients), pseudoaneurysm (4), expanding hematoma (3 injuries in 2 patients). Twenty-two surgical repairs included bypass of severely damaged arteries in five, embolectomy in five, interposition grafts in three, pseudoaneurysm resection and primary repair in three, primary repair of three vascular injuries, and one patch angioplasty. Leg amputation was required in two patients. Seventeen of 19 patients had successful vascular repairs with resolution of preoperative indications for vascular repair without intraoperative or postoperative deaths. Long term follow-up (mean, 17 months) showed no recurrence of vascular problems; however, two patients died of metastatic cancer at 6 and 24 weeks after vascular repair. This study supports an aggressive approach to the management of vascular injuries caused by therapeutic interventions for malignancy despite the presence of metastatic disease.

Oxygen-induced retinopathy in the rat: hemorrhages and dysplasias may lead to retinal detachment.
Penn JS, Tolman BL, Lowery LA, Koutz CA
(1992) Curr Eye Res 11: 939-53
MeSH Terms: Animals, Animals, Newborn, Disease Models, Animal, Humans, Infant, Newborn, Oxygen, Photoreceptor Cells, Rats, Rats, Sprague-Dawley, Retinal Detachment, Retinal Dysplasia, Retinal Hemorrhage, Retinopathy of Prematurity
Show Abstract · Added October 9, 2013
Rearing neonatal rats in hyperoxia induces the development of retinal hemorrhages and retinal dysplasia. Albino rats were placed in 80% oxygen immediately after birth and were exposed for either 5, 10, or 14 days, followed by sacrifice or exposure to normoxia for an additional 2, 4, 5, 7, 8, 10, 38, 45 or 56 days. Control rats were simultaneously raised in room air and sacrificed at the same times. All animals were enucleated and their eyes processed for light and electron microscopy. Eyecups were trimmed to facilitate cross-sectioning of the retina in the vertical meridian. No control rats showed signs of retinal hemorrhages or of dysplastic folds or rosettes. Nor did the retinas of rats killed immediately after oxygen exposure contain hemorrhages, but the incidence of retinal folds or rosettes in this group was 54%. For rats exposed to combinations of hyperoxia and brief normoxia (10 days or less), 40% suffered hemorrhages and 50% developed retinal folds or rosettes. Although hemorrhages were more prominent in rats subjected to longer periods of oxygen (73% of all rats exposed for 14 days followed by brief normoxia vs. 6% of those exposed for 5 days followed by brief normoxia), the incidence decreased with time post-exposure in room air. Hemorrhages occurred in 100% of the rats raised in oxygen for 14 days followed by 2 days in room air, and decreased to 50% by 7 days in room air and to 0% by 38 days, indicating a spontaneous resolution with time. In each case, the blood appeared to leak from the newly-forming vessels of the deep capillary net, with most of the red blood cells migrating to the subretinal space. Retinal fold or rosette formation, indicative of developmental dysplasia, occurred in a fraction of virtually all groups of exposed rats, and persisted at the longest post-exposure periods. These two manifestations of oxygen-induced retinopathy are emphasized because they lead to an abnormal separation of the retina from the epithelial layer, which may increase the likelihood of the most serious consequence of ROP--retinal detachment. In fact, all rats that endured post-exposure periods of 38 days or longer before sacrifice exhibited retinal detachment.

Massive intrahepatic hemorrhage following routine liver biopsy in a patient with rheumatoid arthritis treated with methotrexate.
Cash JM, Swain M, Di Bisceglie AM, Wilder RL, Crofford LJ
(1992) J Rheumatol 19: 1466-8
MeSH Terms: Adult, Arthritis, Rheumatoid, Biopsy, Chemical and Drug Induced Liver Injury, Dose-Response Relationship, Drug, Female, Hemorrhage, Humans, Liver, Liver Diseases, Methotrexate
Show Abstract · Added September 18, 2013
Massive intrahepatic hemorrhage occurred in a patient with rheumatoid arthritis (RA) after a routine liver biopsy done to assess possible methotrexate (MTX) hepatotoxicity. Major complications of liver biopsy occur about once in every 600 biopsies, and mortality from liver biopsy has been reported. Life threatening hepatic toxicity occurs rarely during low dose MTX administration, and it is unclear whether routine liver biopsies identify patients at high risk for these complications. Until the relative risks of liver biopsy and serious MTX liver toxicity are better defined, the use of routine liver biopsies should be recommended only after careful consideration of potential procedural complications in patients with RA treated with MTX.
