CASE PRESENTATION: A 38-year-old Thai woman with systemic lupus erythematosus and myasthenia gravis treated with prednisolone and azathioprine presented to our hospital with low-grade fever, diarrhea, and indurated skin lesions on both thighs. [ncbi.nlm.nih.gov]

• Arthritis

  We report the first case, to our knowledge, of acute purulent arthritis due to Legionella pneumophila in an immunosuppressed patient. [ncbi.nlm.nih.gov]

• Skin Lesion

  Treatment comprised intravenous azithromycin for 3 weeks and the skin lesions, myositis and myocarditis resolved. Oral azithromycin and ciprofloxacin were continued for 3 months to ensure eradication of the organism. [ncbi.nlm.nih.gov]

• Indurated Skin Lesion

She was initially transferred to this institution for definitive workup of presumed B cell lymphoma and, during her hospital course, suffered a relapse of L. pneumophila-associated cellulitis that responded promptly to azithromycin. [ncbi.nlm.nih.gov]

• Colitis

  The first case had been treated initially with 60 mg prednisolone for ulcerative colitis, and L. pneumophila serogroup 1 was isolated from sputum samples after cavitation of the lung lesion. [ncbi.nlm.nih.gov]

To evaluate the effectiveness of different disinfection treatments in a spa water system contaminated by Legionella pneumophila and associated with a case of Legionella pneumonia. [ncbi.nlm.nih.gov]

We examined the clinical characteristics, including symptoms, laboratory findings, radiologic findings, pneumonia severity, initial treatment and prognosis. We also calculated scores using the six-point scoring system in these patients. [ncbi.nlm.nih.gov]

Abstract The use of urinary antigen tests (UATs) may provide early etiology in pneumonia, and facilitates rapid and directed antibiotic treatment. [ncbi.nlm.nih.gov]

Results : Epidemiologically unrelated ST345 isolates were clearly distinguishable from the epidemic clone. [ncbi.nlm.nih.gov]

We discuss the possible mechanisms of L. pneumophila associated acute pancreatitis for which the pathophysiology is still undetermined: infection, toxin release or cytokine secretion. [ncbi.nlm.nih.gov]
