METHODS: This is an open comparative therapeutic trial conducted in the Department of Dermatology, Baghdad Teaching Hospital, Baghdad, Iraq between January and March 2008. Forty patients with perniosis were enrolled in this study, and divided randomly into 2 equal groups, according to the sort of treatment...

Whereas oxygen, continuous positive airway pressure (CPAP) and mechanical ventilation are the mainstays of treatment of pulmonary conditions in newborns, there are a number of adjunctive therapies that may improve the pulmonary function of these infants. These include the use of bronchodilators and diuretics given either systemically or through the inhaled route, mucolytic agents, and anti-inflammatory agents. This chapter gives an overview of the use of the most-studied agents including aerosolized bronchodilators, systemic and inhaled diuretics, and systemic and inhaled corticosteroids in the treatment and prevention of, where appropriate, respiratory distress syndrome, bronchopulmonary dysplasia, and meconium aspiration syndrome...

Behçet's disease is a multisystem inflammatory disorder, characterized by recurrent oral and genital ulceration and uveitis. Additionally, skin lesions, vasculitis, and arthritis may occur. The disease is chronic, with exacerbations and remissions. Treatment of Behcet's disease is symptomatic depending on the symptoms and their severity. Oral ulcers are seen in 98% of patients with Behçet's disease. Some aspects of oral health, such as the amount of plaque and the presence of periodontal disease, and possibly also caries, are more prevalent in patients with the disease when compared to healthy persons...

Hepatic ischemia should be considered in serious liver injury, liver tumor resection and liver transplantation. There are other conditions that decrease hepatic blood flow and cause hepatic ischemia, such as hemorrhagic shock, sepsis, hepatic artery ligation, trauma, and certain vascular lesions. In this study, effects of nimodipine (a calcium channel blocker) and pentoxyfylline (a derivative of methylxanthine) on duration and degree of hepatic ischemia in rats at normothermic and hypothermic conditions are investigated...

A 7-year-old girl of Colombian descent was referred for diagnosis and treatment. She initially presented signs of universal itchy eczema in the spring of 2003. She responded to local treatment with topical steroids, but her symptoms rapidly re-emerged after discharge. Further investigations led to the conclusion that the patient suffered from Actinic Prurigo. The disease was very severe and there was a lack of response to treatment with oral prednisolone, antihistamines and pentoxyfyllin. Therefore the patient was treated with Thalidomide 50 mg/25 mg daily (alternating)...

A fixed combination of aescin and troxerutin has been developed for treating inner ear perfusion problems of different aetiology. The efficacy of this combination is tested versus pentoxyfyllin in a randomized clinical study as group comparison with 34 patients for each group. The improvement of hearing after 40-44 days of treatment is determined as end point of treatment. Hearing was measured by threshold, whereby a difference of more than 10dB is judged as a significant improvement. After the treatment with the combination of aescin and troxerutin hearing is significantly improved, in 23 of 34 patients the threshold is changed more than 10dB, which is checked by sign-test with p<0...

Advanced glycation endproducts (AGEs) are unavoidable byproducts of various metabolic pathways. They are formed by reactive metabolic intermediates such as methylglyoxal (MG), glyoxal, and 3-deoxyglucosone. These reactive intermediates bind to proteins, DNA, and other molecules and disrupt their structures and functions, which leads to different diseases such as vascular complications of diabetes, atherosclerosis, hypertension, Alzheimer's disease, and aging. In recent years, more compounds that prevent the formation of AGEs or degrade the existing AGEs have been produced and patented...

Treatment options for IgA nephropathy (IgAN) must take into consideration the pathophysiology, namely the role of eicosanoids, angiotensin II and monocyte-macrophages releasing reactive oxygen species (ROS). Angiotensin converting enzyme inhibitors and early corticosteroid usage are prime therapies. Tonsillectomy should be considered. Other components of a therapeutic cocktail could be; (a) thromboxane antogonist, (b) leukotriene antagonist, (c) platelet activating factor antagonist, (d) an anti-oxidant and (e) an anti-fibrotic agent like pentoxyfylline...

The mass flows of selected pharmaceuticals and personal care products (PPCPs) were studied in the aqueous compartment of the river Somes in Romania. PPCPs were measured in wastewater treatment effluents and in the receiving river water. The analytical method for the determination of PPCPs in river water was based on solid phase extraction and GC-ITMS. Carbamazepine, pentoxyfylline, ibuprofen, diazepam, galaxolide, tonalide and triclosan were determined in wastewater effluents with individual concentrations ranging from 15 to 774 ng L(-1)...

BACKGROUND AND AIM: Inhibition of tumor necrosis factor (TNF)-alpha is a logical approach to manage patients with non-alcoholic steatohepatitis (NASH). Pentoxifylline reduces TNF-alpha and alanine aminotransferase (ALT) levels in patients with NASH. The aim of the present paper was to study if pentoxifylline can improve histological injury in patients with NASH. METHODS: Nine patients (mean age 31.6 +/- 7.2 years) with histologically proven NASH and with persistently elevated ALT (>1...

BACKGROUND: The main object of this study was to find out what treatment methods are currently preferred for central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) in Germany, Austria and Switzerland. METHODS: A questionnaire concerning the different medicamentous, surgical and laser treatments available for CRVO and BRVO was developed and sent out to the members of the German Retina Society. RESULTS: This analysis is based on 124 returned questionnaires...

The pharmacokinetic properties of pentoxyfylline and its metabolites were determined in healthy chickens after single intravenous and oral dosage of 100 mg/kg pentoxyfylline. Plasma concentrations of pentoxyfylline and its metabolites were determined by a validated high-performance liquid chromatographic method. After intravenous (i.v.) and oral (p.o.) administration, the plasma concentration-time curves were best described by a one-compartment open model. The mean elimination half-life (t(1/2el)) of pentoxyfylline was 1...

The effects of vitamin A, pentoxyfylline and methylprednisolone on experimentally induced amyloid arthropathy were investigated. In this study, 175 1-day-old brown layer chicks were used. Throughout the study Group II (vitamin A) received high doses of vitamin A (75,000 IU/kg), whereas Group I (negative control), Group III (positive control), Group IV (pentoxyfylline) and Group V (methylprednisolone) received normal levels of vitamin A in the diet. At the fifth week, the experimental Groups II, III, IV and V were injected with Freund's adjuvant intra-articularly to induce amyloid arthropathy...

Evidence from both experimental and clinical trials indicates that inflammatory mediators are important in the pathogenesis of chronic heart failure (HF), contributing to cardiac remodelling and peripheral vascular disturbances. Several studies have shown raised levels of inflammatory cytokines such as TNF-alpha, IL-1beta and -6 in HF patients in plasma, circulating leukocytes, atherosclerotic lesions, and in the failing myocardium itself. Importantly, this rise in inflammatory mediators does not seem to be accompanied by a corresponding increase in anti-inflammatory cytokines such as IL-10 and transforming growth factor-beta; thus resulting in an inflammatory imbalance in the cytokine network...

BACKGROUND: Thrombomodulin (TM) is an endothelial receptor that exerts anti-coagulant, anti-fibrinolytic, and anti-inflammatory activity by inhibiting thrombin and cellular adhesion. There is growing evidence that TM plays a role in tumour behaviour. METHODS: The electronic literature (1966-2004) was reviewed with a specific focus on tumour biology. RESULTS: TM is expressed on both the endothelium and tumour cells in several cancers. Loss of expression denotes a more malignant profile with poorer prognosis...

DESIGN: A multi-arm, modified blinded, placebo-controlled design was used. SETTING: The studies were conducted at the Boston VA Healthcare System and the Boston University School of Medicine Medication Development Research Unit (MDRU). PARTICIPANTS: Participants met criteria for cocaine dependence during a 2-week screening period...

Pharmacotherapy is limited for the relief of intermittent claudication (IC), a common manifestation of peripheral arterial disease (PAD). Pentoxyfylline, the only current pharmacological therapy for IC, has been shown to have similar efficacy as placebo. Cilostazol, a new phosphodiesterase III (PDE III) inhibitor, is a potent inhibitor of platelet aggregation with vasodilatory, antithrombotic, antiproliferative and positive lipid-altering effects. To evaluate the efficacy and safety of cilostazol for the treatment of IC in Indian patients, 123 patients were selected from 6 centres in India...

The anti-inflammatory effects of pentoxfylline are associated with a number of clinical benefits. These include reduction in mortality in patients who have undergone bone marrow transplants or suffer peritonitis. In infants with sepsis, a reduction in mortality has also been associated with pentoxyfylline administration. The anti-inflammatory effects of pentoxyfylline, as well as its bronchodilator, diuretic and respiratory muscle stimulant effects suggest it may have a useful role in BPD. Interim analysis of a prophylactic trial suggests pentoxyfylline may reduce treatment requirements after the neonatal period and that, in established BPD, pentoxyfylline and dexamethasone may be of similar efficacy...

Samples of influent (untreated) and effluent (treated) from 18 sewage treatment plants (STPs) in 14 municipalities in Canada were analyzed for residues of selected prescription and nonprescription drugs. Several neutral and acidic drugs were detected in effluents, including analgesic/anti-inflammatory agents, lipid regulators, and an antiepileptic drug, carbamazepine. Residues were extracted from effluents by solid-phase extraction, followed by either methylation and analysis of acidic drugs by gas chromatography/mass spectrometry or direct analysis of neutral drugs by liquid chromatography/tandem mass spectrometry...
