The results showed that both dehydroleucodine and Artemisia douglasiana extract had activity against the microorganism with MICs between 1-8 and 60-120 mg/L, respectively.
H. pylori-positive patients self-administered lansoprazole, 30 mg; clarithromycin, 500 mg; and metronidazole, 500 mg bid for 7 days. Patients were assessed at pretreatment, at which time the presence of H. pylori was documented by rapid urease test or histology and culture, following study drug administration (week 1) for a brief evaluation only, and at least 4 weeks posttreatment (week 5), including endoscopy with collection of biopsy specimens for culture and histology testing.

A 54-year-old man with asthma, mitral valve prolapse, and a back injury developed erythematous nodules that progressed along the lymphatic drainage of his right arm. Skin biopsy revealed granulomatous inflammation with microabscess formation. Culture confirmed Mycobacterium marinum infection. The patient was treated with clarithromycin, ethambutol, rifampin, and topical silver sulfadiazine. Oral doxycycline hyclate was later added because of slow healing. Mycobacterium marinum is one of a group of infectious agents that can cause nodular lymphangitis. Sporotrichoid lesions most commonly develop after cutaneous inoculation with Sporothrix schenckii, Leishmania species, Nocardia species, and Mycobacterium marinum. A thorough clinical history and physical examination can narrow the differential diagnosis by eliciting information about the etiologic setting, incubation time, clinical appearance of the lesions, and presence or absence of systemic involvement for each of the causative organisms. Skin biopsy and microbiological tissue cultures are essential for diagnostic confirmation. The differential diagnosis and a suggested diagnostic paradigm will be reviewed.
Minimum inhibitory concentration (MIC) values of Brucella reference strains and three marine isolates to antibiotics binding the ribosome ranged from 0.032 to >256 microg/ml for the macrolides erythromycin, clarithromycin, and azithromycin and 2 to >256 microg/ml for the lincosamide, clindamycin. Though sequence polymorphisms were identified among ribosome associated loci 23S rrn, rplV, tuf-1 and tuf-2 but not rplD, they did not correlate with antibiotic resistance phenotypes. When spontaneous erythromycin resistant (eryR) mutants were examined, mutation of the peptidyl transferase center (A2058G Ec) correlated with increased resistance to both erythromycin and clindamycin. Brucella efflux was examined as an alternative antibiotic resistance mechanism by use of the inhibitor L-phenylalanine-L-arginine beta-naphthylamide (PAbetaN). Erythromycin MIC values of reference and all eryR strains, except the B. suis eryR mutants, were lowered variably by PAbetaN. A phylogenetic tree based on concatenated ribosomal associated loci supported separate evolutionary paths for B. abortus, B. melitensis, and B. suis/B. canis, clustering marine Brucella and B. neotomae with B. melitensis. Though Brucella ovis was clustered with B. abortus, the bootstrap value was low.

The guideline of the Korean College of Helicobacter and Upper Gastrointestinal Research group for Helicobacter pylori infection was first produced in 1998, when definite indication for H. pylori eradication is early gastric cancer in addition to the previous indications of peptic ulcer (PUD) including scar lesion and marginal zone B cell lymphoma (MALT type). Though treatment is recommended for the relatives of a patient with gastric cancer, unexplained iron deficiency anemia, and chronic idiopathic thrombocytopenic purpura, a consensus treatment guideline is the treatment of PUD, MALToma, and gastric cancer in Korea. One- or 2-week treatment with proton pump inhibitor (PPI)-based triple therapy consisting of one PPI and 2 antibiotics, clarithromycin and amoxicillin, is recommended as the first-line treatment regimen. In the case of treatment failure, one or 2 weeks of quadruple therapy (PPI + metronidazole + tetracycline + bismuth) is recommended, whose eradication regimen was not different between Korea and Japan. Though the treatment regimen was similar between two nations, the Japanese government declared the inclusion of H. pylori eradication in patients with H. pylori-associated chronic gastritis, reaching the conclusion that the treatment guideline became quite different between Korea and Japan from February 21, 2013. The prime rationale of the Japanese extended treatment guideline for H. pylori infection was based on the drastic intention to prevent gastric cancer as well as the improvement of chronic gastritis-associated functional dyspepsia based on their findings that H. pylori eradication might decrease gastric cancer incidence as well as mortality. In this review, the discrepancy between the Korean and Japanese treatment guidelines will be explained; why and how?

A clinical syndrome represented by the association of Mycobacterium avium complex (MAC) infection with initiation of highly active antiretroviral therapy (HAART) has been recently described in patients with advanced HIV disease. HAART-associated improvement of the immune status might convert a clinically silent MAC infection into an active mycobacterial disease. A 40-year-old man with severe factor VII deficiency, advanced HIV-1 disease, a CD4 + lymphocyte count of 15 cells microL-1 (CDC stage A3) and 470,000 HIV-RNA copies mL-1 (measurement by NASBA system) underwent standard HAART (lamivudine, stavudine and ritonavir). Two weeks after HAART onset, the patient developed enlargement of the lymph nodes throughout the mesentery and after seven weeks a rapidly enlarging mass on the left side of the neck. Culture from a needle aspirate specimen revealed MAC. His CD4 + count had increased to 97 cells microL-1 and viraemia dropped to undetectable HIV-RNA copies. While continuing antiviral therapy, multidrug therapy for MAC infection (clarithromycin, ciprofloxacin, ethambutol, amikacin) was started with progressive improvement and cure of the neck mycobacterial infection and disappearance of the abdominal lymph nodes. HAART has been shown to offer significant clinical and laboratory benefits in terms of HIV disease with limited side-effects in Haemophiliacs. However, the clinical manifestation of an opportunistic infection should be mentioned as a possible complication of HAART in these patients, as well as in other categories of HIV infected patients, and in patients with congenital coagulopathies.

A 58-year-old man was seen with complaints of fevers, night sweats, weight loss, and multiple bilateral cavitary lung lesions. Mycobacterium szulgai with nearly identical antibiograms grew from separate sputum specimens 9 years apart. He was treated with a combination of clarithromycin and ethambutol with clinical, microbiologic, and radiographic resolution of disease. This is the longest untreated case of documented Mycobacterium szulgai infection reported, and offers a glimpse of its natural history when left untreated. Despite an infrequent isolation (<0.5% of cases), it is a pathogenic organism which warrants treatment.

Helicobacter pylori infection is very common in India, as in other developing countries, but few data exist on the susceptibility of H. pylori to antimicrobial agents commonly used for eradication here.

To determine if microbiologic cure of AIDS-related disseminated Mycobacterium avium complex (MAC) is possible in patients receiving highly active antiretroviral therapy (HAART), 4 patients with a history of disseminated MAC received >/=12 months of macrolide-based antimycobacterial therapy. All were asymptomatic and had absolute CD4 cell count >100/microL (range, 137-301) and <10,000 copies/mL of human immunodeficiency virus RNA (range, <500-1250). A bone marrow aspirate and peripheral blood were obtained for mycobacterial culture. Follow-up blood cultures were obtained routinely at 4 weeks and every 8 weeks thereafter. All 4 patients had negative bone marrow and blood cultures and then discontinued antimycobacterial therapy. All patients' subsequent cultures remain sterile and all are clinically asymptomatic (range, 8-13 months follow-up). It appears that disseminated MAC infection can be cured by prolonged antimycobacterial therapy in some persons who experience sustained CD4 lymphocyte increases while receiving HAART.
The objective of this study was to compare the relative bioavailability and bioequivalence of a test (Claromycin®, GA Pharmaceuticals) and a reference (Klaricid®, Abbott) tablet containing 500mg clarithromycin in healthy volunteers under fasting conditions.
