AIMS: To ascertain the prevalence of acute trachoma as a supposed endemic disease among infants in the Saharan refugee camps of Tindouf (Algeria) and to evaluate the efficacy of treatment with a single dose of azithromycin. METHODS: 527 children aged between 3 and 17 were evaluated in the camp schools in October 2001. All the children were clinically and microbiologically examined, including slit lamp checks of anterior segment and two conjunctival swabs, one for the detection of membrane lipopolysaccharide by quick immunoassay test Clearview Chlamydia MF and the other for the detection of specific DNA by chlamydia plasmid specific polymerase chain reaction (PCR) assay. After examination, a single dose of azithromycin was administered to each child. One month later samples from positive children and 12 random negative children by the first PCR were taken to perform a new PCR assay. RESULTS: Chlamydia trachomatis was suspected in 2.47% of the children, papillary hypertrophy being the most frequently seen clinical sign. Scarring changes secondary to trachoma were detected in 11.7% of the children. Only four cases (0.8%) were positive to the immunoassay test and 12 cases (2.27%) were positive by PCR. After treatment a second PCR was performed on positive children and they were negative of chlamydia DNA amplification. However, one child who was negative and received the treatment was positive in the second PCR assay. CONCLUSION: Acute trachoma prevalence is much lower than expected among infants in this Saharan population. The possible reasons could be the recent improvements in hygiene and health care. Cicatricial trachoma is more frequent. The Clearview immunoassay test has very low sensitivity in the detection of this disease. A single dose of azithromycin is sufficient to treat chlamydial conjunctivitis. However, a programme of improvement in hygiene and health care is necessary to prevent re-infection.

The in-vitro activity of moxifloxacin, a new 8-methoxyquinolone, was compared with minocycline and azithromycin against 40 strains of Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia psittaci. Both the MIC and the MBC of moxifloxacin ranged from 0.03 to 0.125 mg/L. MICs of minocycline ranged from 0.015 to 0.06 mg/L and MBCs between 0.03 and 0.25 mg/L. MICs of azithromycin ranged from 0.03 to 0.125 mg/L and the MBCs between 0.06 and 0.5 mg/L. MBC values of moxifloxacin were the same as MICs in 32 (80%) of 40 strains tested, whereas those of minocycline and azithromycin were two to four times higher than their MICs. These data confirm those previously obtained indicating that quinolones kill chlamydial strains at concentrations equivalent to their MICs.

BACKGROUND: Helicobacter pylori infection is highly prevalent and may cause disease in 10% to 15% of infected individuals: duodenal and gastric ulcer, gastric cancer and gastric lymphoma. Guidelines for a test-and-treat policy have been published by the European H. pylori working group in Maastricht. GOALS: To assess the current approach to H. pylori-related diseases, indications for testing and eradication therapy, among internists and surgeons of a University affiliated medical center. STUDY: A 15-items questionnaire was formulated according to the Maastricht II test-and-treat recommendation and distributed among the physicians of 6 internal medicine departments and the department of surgery. The questionnaires were completed anonymously at the department's staff meeting, under the supervision of the head of the department. All questions required a yes/no answer; the maximum possible score was 15. The relative ratio (RR) of correct answers was calculated for every question and by subgroups as follows: all participants, internists, surgeons, experts and residents in internal medicine and surgery. RESULTS: The response rate was 68% (55 out of 80 physicians). Total score for all participants was 10.9 (RR = 0.73), significantly lower than the maximum score of 15 (RR = 1.00). The internists had significantly higher average score than the surgeons for 2 questions: causative agent in gastric cancer (p = 0.003) or gastric lymphoma (p = 0.003), 1 question about triple therapy, PPI, penicillin and azythromycin being not recommended (p = 0.022), and for 1 question of test-and-treat policy: should this strategy apply to family members of gastric cancer patients (p = 0.045). Only 56% of the internists and 21% of surgeons knew what MALToma is, and the correlation with H. pylori infection. CONCLUSION: Knowledge of Surgeons and Internists regarding infection and correlation with diseases or test and treat policy should be improved.
