Trial of Antimycobacterial Therapy in Sarcoidosis

2014-08-27 03:15:41 | BioPortfolio

Summary

Growing research from independent laboratories provide an association between mycobacteria and sarcoidosis. More recent immunologic and molecular studies demonstrate immune responses to mycobacteria virulence factors. We hypothesize that sarcoidosis pathogenesis reflects an immune response against metabolically-active mycobacterial species. The purpose of this study is to assess if administration of anti-mycobacterial drug therapy will aid in resolution of cutaneous sarcoidosis lesions.

Sarcoidosis diagnostic score (SDS): a systematic evaluation to enhance the diagnosis of sarcoidosis.

The diagnosis of sarcoidosis is made by the combination of clinical features and biopsy results. The clinical features of sarcoidosis can be quite variable. We developed a Sarcoidosis Diagnostic Score...

Pleuroparenchymal sarcoidosis - A recognised but rare manifestation of disease.

Pleural involvement is rare in sarcoidosis. The presence of a large symptomatic effusion in a patient with sarcoidosis should therefore prompt further investigation for an alternate aetiology. Here we...

Cutaneous sarcoidosis - a great imitator.

Skin manifestation occurs in approximately 25% of patients with sarcoidosis and is often the first symptom of the disease. The availability of skin biopsy material is helpful in establishing the early...

To describe changes in the retina during ethambutol-induced optic neuropathy (EON) progression, and determine the retinal layer thickness as a predictive factor for vision recovery after stoppage of e...

Obesity and sarcoidosis: consequence or contributor?

Sarcoidosis is a multisystem disease of unknown cause. Obesity can affect many physiological factors. The relationship between obesity and sarcoidosis is unclear, and can been described as posing a 'c...

Medical and Biotech [MESH] Definitions

Sarcoidosis affecting predominantly the lungs, the site most frequently involved and most commonly causing morbidity and mortality in sarcoidosis. Pulmonary sarcoidosis is characterized by sharply circumscribed granulomas in the alveolar, bronchial, and vascular walls, composed of tightly packed cells derived from the mononuclear phagocyte system. The clinical symptoms when present are dyspnea upon exertion, nonproductive cough, and wheezing. (Cecil Textbook of Medicine, 19th ed, p431)

A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p1160)

A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.

An antitubercular agent that inhibits the transfer of mycolic acids into the cell wall of the tubercle bacillus. It may also inhibit the synthesis of spermidine in mycobacteria. The action is usually bactericidal, and the drug can penetrate human cell membranes to exert its lethal effect. (From Smith and Reynard, Textbook of Pharmacology, 1992, p863)

Tuberculosis resistant to ISONIAZID and RIFAMPIN and at least three of the six main classes of second-line drugs (AMINOGLYCOSIDES; polypeptide agents; FLUOROQUINOLONES; THIOAMIDES; CYCLOSERINE; and PARA-AMINOSALICYLIC ACID) as defined by the CDC.
