RESUMO
In 2011, autochthonous Plasmodium vivax malaria emerged in a focal geographical area in Greece after importation by immigrants from the Indian subcontinent. We report the case of complicated P. vivax malaria in a previously healthy 42-year-old Greek female. The patient presented acute respiratory distress syndrome (ARDS), worsening jaundice, and thrombocytopenia after the administration of antimalarial treatment and despite a decreasing burden of parasitemia. She recovered fully after admission in the intensive care unit and support with mechanical ventilation. We discuss the risks potentially associated with the reappearance of P. vivax malaria in a previously malaria-free area.

A matched 1:3 case-control study investigated factors predicting colistin-resistant versus colistin-susceptible KPC-producing Klebsiella pneumoniae acquisition and its impact on patient outcomes. Case patients were more often admitted from other institutions (P = 0.019) and had longer therapy with beta-lactam/beta-lactamase inhibitors (P = 0.002) and higher overall mortality (P = 0.05). All 52 study isolates were clonally related, suggesting horizontal dissemination. None of these parameters independently predicted colistin resistance, which probably occurred in a susceptible KPC-KP strain that was subsequently disseminated horizontally.

The objectives of this study were to explore the epidemiological features and resistance rates in uropathogens isolated from cases of acute uncomplicated cystitis (AUC) in Greece, and subsequently to guide empirical treatment. Urine samples from outpatients aged >16 years were cultured and for each uropathogen isolated non-susceptibility to orally administered antimicrobial agents was defined. Demographic and clinical data were provided in questionnaire form. From January 2005 to March 2006 a total of 1936 non-duplicate positive urinary cultures were collected and 889 AUC cases were evaluated. Escherichia coli was the main aetiological agent (83%). In the AUC group, non-susceptibility rates for E. coli isolates were as follows: amoxicillin 25.8%; co-trimoxazole 19.2%; cefalothin 14.9%; nitrofurantoin 10.7%; amoxicillin/clavulanic acid 5.2%; nalidixic acid 6%; mecillinam 3.4%; ciprofloxacin 2.2%; cefuroxime 1.7%, and fosfomycin 1.6%. Amoxicillin and/or co-trimoxazole use in the previous 3 months was significantly associated with isolation of a co-trimoxazole-resistant E. coli isolate. The same applied for previous use of a fluoroquinolone agent and isolation of a ciprofloxacin-resistant E. coli isolate. In conclusion, increased co-trimoxazole non-susceptibility rates undermine its use as a first-line agent in empirical treatment, especially in cases of recent use of co-trimoxazole and/or amoxicillin. Fluoroquinolones display potent in vitro activity against community uropathogens, but prudent use is warranted for uncomplicated infections. Mecillinam and nitrofurantoin could serve as effective front-line agents in an effort to design fluoroquinolones-sparing regimens.
