BACKGROUND: Treponema pallidum subspecies pertenue causes yaws. Strategies to better control, eliminate, and eradicate yaws are needed. METHODS: In an open-label, cluster-randomized, community-based trial conducted in a yaws-endemic area of Papua New Guinea, we randomly assigned 38 wards (i.e., clusters) to receive one round of mass administration of azithromycin followed by two rounds of target treatment of active cases (control group) or three rounds of mass administration of azithromycin (experimental group); round 1 was administered at baseline, round 2 at 6 months, and round 3 at 12 months. The coprimary end points were the prevalence of active cases of yaws, confirmed by polymerase-chain-reaction assay, in the entire trial population and the prevalence of latent yaws, confirmed by serologic testing, in a subgroup of asymptomatic children 1 to 15 years of age; prevalences were measured at 18 months, and the between-group differences were calculated. RESULTS: Of the 38 wards, 19 were randomly assigned to the control group (30,438 persons) and 19 to the experimental group (26,238 persons). A total of 24,848 doses of azithromycin were administered in the control group (22,033 were given to the participants at round 1 and 207 and 2608 were given to the participants with yaws-like lesions and their contacts, respectively, at rounds 2 and 3 [combined]), and 59,852 doses were administered in the experimental group. At 18 months, the prevalence of active yaws had decreased from 0.46% (102 of 22,033 persons) at baseline to 0.16% (47 of 29,954 persons) in the control group and from 0.43% (87 of 20,331 persons) at baseline to 0.04% (10 of 25,987 persons) in the experimental group (relative risk adjusted for clustering, 4.08; 95% confidence interval [CI], 1.90 to 8.76). The prevalence of other infectious ulcers decreased to a similar extent in the two treatment groups. The prevalence of latent yaws at 18 months was 6.54% (95% CI, 5.00 to 8.08) among 994 children in the control group and 3.28% (95% CI, 2.14 to 4.42) among 945 children in the experimental group (relative risk adjusted for clustering and age, 2.03; 95% CI, 1.12 to 3.70). Three cases of yaws with resistance to macrolides were found in the experimental group. CONCLUSIONS: The reduction in the community prevalence of yaws was greater with three rounds of mass administration of azithromycin at 6-month intervals than with one round of mass administration of azithromycin followed by two rounds of targeted treatment. Monitoring for the emergence and spread of antimicrobial resistance is needed. (Funded by Fundació "la Caixa" and others; ClinicalTrials.gov number, NCT03490123.).

Synonyma tropického vředu jsou pouštní vřed či tropická fagedena. Je to vřed způsobený většinou smíšenou bakteriální infekcí (nejčastěji streptokoky a směsí gramnegativních bakterií zjištěných v kultuře), obvykle se vyskytující po traumatických ranách na dolních končetinách, často u pacientů v malnutrici a s chronickými chorobami. Vyskytuje se v teplém a vlhkém klimatu, primárně u dospělých. Epidemicky se může vyskytnout v militárních skupinách či u dělníků na polích. Nejběžnější terapií je Penicilin pro jeho cenu a dostupnost v chudých oblastech. V případě alergie na Penicilin lze použít cefalosporiny, aminoglykosidy či ciprofloxacin. Též důležitá je péče o adekvátní výživu, vitaminy a dostatečnou podpůrnou léčbu. Z hlediska lokální terapie se jedná o běžnou léčbu ran (1). Ve článku je popsán případ pacienta, který se vrátil z dovolené v Thajsku se vředem na bérci a vyšetřeními byl nález uzavřen jako tropický vřed. Léčba probíhala za hospitalizace a posléze ambulantně.

The synonyms of ulcus tropicum are desert ulcer or tropical phagedena. It is ulcer almost caused by mixed bacterial infection (the most often streptococci and a variety of gramnegative organisms in culture), usually involving traumatic wounds of the legs, often in patients with malnutrition and with chronic diseases. It´s occur usually in warm, damp climates, primarily in adults. Epidemics may occur in military troops or plantation workers. Penicilin is most often used therapy because of its price and availability in poor regions. In case of allergy is possible to use cephalosporins, aminoglycosides or ciprofloxacin. Also important is care about adequate nutrition, vitamins and good supportive care. The local therapy is common wound care (1). In the article is presented a case report of patient, who returned from vacation in the Thailand with the ulcer on crura and the investigation was closed like ulcus tropicum. Also in the article there are the informations about treatment in hospital and then ambulancy.

Půda s amikacinem k záchytu beta-hemolytických streptokoků

Beta-hemolytické streptokoky se uplatňují jako etiologické agens sekundárních infekcí ran, ulcerací a dekubitů. Jejich laboratorní diagnostika bývá komplikována tím, že se na infekci často podílejí i další, růstově méně náročné bakterie (Staphylococcus aureus, pseudomonády a enterobakterie). Ty na krevním agaru přerůstají kolonie beta-hemolytických streptokoků. Byl srovnán záchyt beta-hemolytických streptokoků na krevním agaru a na selektivním krevním agaru s přídavkem amikacinu (36 μg/ ml). Celkem bylo vyšetřeno 836 vzorků od 782 pacientů. Zachyceno bylo 86 izolátů beta-hemolytických streptokoků. V 73 případech byly identifikovány další bakteriální druhy podílející se na infekci. Nejčastěji to byl S. aureus a Pseudomonas aeruginosa. U vzorků, kde byla zjištěna smíšená infekce, bylo 46 izolátů beta-hemolytických streptokoků zachyceno jak na krevním agaru, tak na krevním agaru s amikacinem. Dalších 27 izolátů bylo zachyceno pouze na krevním agaru s amikacinem. Bez použití selektivní půdy by uniklo 37 % izolátů beta-hemolytických streptokoků u vzorků z kožních lézí.

Beta-haemolytic streptococci are implicated in the etiology of secondary wound infection, ulcerations and decubitus ulcers. Laboratory diagnosis of these causative agents is complicated by the fact that other less fastidious bacteria (Staphylococcus aureus, pseudomonads and enterobacteria) may also be involved in the infection. On blood agar, these bacteria overgrow colonies of beta-haemolytic streptococci. Detectability of beta-haemolytic streptococci on blood agar and selective blood agar added with amikacin (36 μg/ ml) was compared. A total of 836 specimens from 782 patients were examined. Eighty-six isolates of beta-haemolytic streptococci were detected. Coinfection with other bacterial species, most frequently identified as Staphylococcus aureus and Pseudomonas aeruginosa, was observed in 73 specimens. Forty-six isolates of beta-hemolytic streptococci involved in coinfection were detected on both blood agar and blood agar with amikacin. Twenty-seven additional isolates were only recovered on blood agar with amikacin. Without the use of selective medium, 37 % of isolates of beta-haemolytic streptococci from skin lesion specimens would escape detection.
