The Role Of Allograft Inflammatory Factor 1 In Systemic Sclerosis, Francesco Del Galdo, Carol M. Artlett, Sergio A. Jimenez Nov 2006

The Role Of Allograft Inflammatory Factor 1 In Systemic Sclerosis, Francesco Del Galdo, Carol M. Artlett, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

ABSTRACT

Purpose: To review studies which support the hypothesis that allograft inflammatory factor-1 (AIF-1), a protein initially identified in chronically rejected cardiac allografts, may be involved in the pathogenesis of the progressive fibroproliferative vasculopathy which is a hallmark of systemic sclerosis (SSc).

Recent findings: Recent findings demonstrated elevated AIF-1 expression both in SSc affected tissues and peripheral blood mononuclear cells. A detailed immunohistopathologic study examined the tissue and cellular localization of the protein in affected SSc tissues and demonstrated its expression in the endothelium of dermal and pulmonary vessels, in the pulmonary parenchyma, and in relevant inflammatory cells including T …


Description Of Twelve Cases Of Nephrogenic Fibrosing Dermopathy And Review Of The Literature, Fabian A. Mendoza, Carol M. Artlett, Nora Sandorfi, Kevin Latinis, Sonoles Piera-Velazquez, Sergio A. Jimenez Feb 2006

Description Of Twelve Cases Of Nephrogenic Fibrosing Dermopathy And Review Of The Literature, Fabian A. Mendoza, Carol M. Artlett, Nora Sandorfi, Kevin Latinis, Sonoles Piera-Velazquez, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

ABSTRACT

Objectives: To review the clinical and laboratory features of twelve cases of nephrogenic fibrosing dermopathy (NFD) studied at our institution and of 70 previously described cases in the literature.

Methods: Clinical evaluation and laboratory studies of twelve patients with NFD associated with chronic hemodialysis or peritoneal dialysis for end-stage renal disease and a review of 23 previous publications describing 70 patients with this disease.

Results: Eleven patients undergoing chronic hemodialysis and one patient undergoing chronic peritoneal dialysis for end-stage renal failure developed a severe and progressive cutaneous fibrotic process with woody induration of legs, thighs, hands and forearms, and …


Inhibition Of Collagen Gene Expression In Systemic Sclerosis Dermal Fibroblasts By Mithramycin, Nora Sandorfi, Natalia Louneva, Elena Hitraya, Gyorgy Hajnoczky, Biagio Saitta, Sergio A. Jimenez Dec 2005

Inhibition Of Collagen Gene Expression In Systemic Sclerosis Dermal Fibroblasts By Mithramycin, Nora Sandorfi, Natalia Louneva, Elena Hitraya, Gyorgy Hajnoczky, Biagio Saitta, Sergio A. Jimenez

Selected Works of Sergio Jiménez, MD, MACR

ABSTRACT

Introduction. The antitumor antibiotic mithramycin has also been shown to be a potent and effective inhibitor of fibrosis following glaucoma surgery. This DNA interacting drug displays high affinity binding to GC rich sequences in DNA, including those present in the promoter of the gene encoding the Α1 chain of type I collagen (COL1A1).

Objective. To evaluate the effects of mithramycin on the production of type I collagen in fibroblast cultures from patients with systemic sclerosis. Methods. Confluent cultures of dermal fibroblasts from patients with recent onset of the diffuse form of systemic sclerosis were treated with varius concentrations of …

Utilization Of Juvenile Animals Studies To Determine The Human Effects And Risks Of Environmental Toxicants During Postnatal Developmental Stages, Robert L. Brent Jan 2004

Utilization Of Juvenile Animals Studies To Determine The Human Effects And Risks Of Environmental Toxicants During Postnatal Developmental Stages, Robert L. Brent

The Selected Works of Robert Brent

Toxicology studies utilizing animals and in-vitro cellular or tissue preparations have been used to study the toxic effects and mechanism of action of drugs and chemicals and to determine the effective and safe dose of drugs in humans and the risk of toxicity from chemical exposures. Testing in animals could be improved if animal dosing using the mg/kg basis was abandoned and drugs and chemicals were administered to compare the effects of pharmacokinetically and toxicokinetically equivalent serum levels in the animal model and human. Since alert physicians or epidemiology studies, not animal studies have discovered most human teratogens and toxicities …

Medical, Social And Legal Implications Of Treating Nausea And Vomiting Of Pregnancy, Robert L. Brent Jan 2002

Medical, Social And Legal Implications Of Treating Nausea And Vomiting Of Pregnancy, Robert L. Brent

The Selected Works of Robert Brent

This article will deal with medical, social, and legal implications of treating nausea and vomiting of pregnancy (NVP). Clinical problems occur when the symptoms become exaggerated and result in debilitation, dehydration, and hospitalization. The treatment of NVP in its early stages has the implication that it will prevent the more serious complications, including hospitalization. Therapeutic modalities discussed in this conference that have been used or are being tested are primarily symptomatic treatments (antihistamines, Bendectin (Merrell Dow; Cincinatti, Ohio), phenothiazines, hyponosis, accupressure, relaxation behavioral modification, audiogenic feedback training, newer medications, diet, and nutritional support). Bendectin is probably the most studied medication …


Teratogen Update: Reproductive Risks Of Leflunomide (Arava); A Pyrimidine Synthesis Inhibitor: Counseling Women Taking Leflunomide Before Or During Pregnancy And Men Taking Leflunomide Who Are Contemplating Fathering A Child, Robert L. Brent Feb 2001

Teratogen Update: Reproductive Risks Of Leflunomide (Arava); A Pyrimidine Synthesis Inhibitor: Counseling Women Taking Leflunomide Before Or During Pregnancy And Men Taking Leflunomide Who Are Contemplating Fathering A Child, Robert L. Brent

The Selected Works of Robert Brent

Arava™ (leflunomide) is a pyrimidine synthesis inhibitor used in the treatment of active rheumatoid arthritis (RA). The chemical name for leflunomide is N- (4’-trifluoromethylphenyl)-5-methylisoxazole-4-carboxamide. Because the drug has been successful in the treatment of rheumatoid arthritis (RA), it is being widely prescribed. In spite of the clear warning that the drug should not be prescribed for pregnant women, approximately 30 women have become pregnant while taking leflunomide as of December 1999. This commentary was prepared to aid teratology counselors and genetic counselors that might be contacted by physicians or patients about the risk of leflunomide exposure during pregnancy. Before the …
