[Epidemiology and clinical features in diabetic patients with invasive infections treated at the Clinical Hospital of Infectious Diseases of Iasi, Romania, between 2008-2010]. / Cercetari clinico-epidemiologice retrospective asupra infectiilor invazive la bolnavii diabetici în spitalul clinic de boli infectioase Iasi, în perioada 2008-2010.

UNLABELLED: Infections in the diabetic population can be severe and life threatning at least for two reasons: clinical signs are often torpid, masqued by chronical complications of diabetes leading to late recognition and medical adresability and also because of the inability to control established infection due to complex cell-mediated and humoral immunity deffects. The aim of the study was to evaluate the etiology, clinical features and outcome in diabetic patients with invazive disease. MATERIAL AND METHODS: A retrospective study was conducted between January 2008 and December 2010 at The Clinical Hospital of Infectious Diseases Iasi among 75 diabetic patients with sepsis of microbiologically confirmed etiology (positive cultures from normally sterile sites) and sepsis with clinically suspected etiology (positive cultures from pus). Cases with positive urocultures and coprocultures only, were excluded. RESULTS: From 75 diabetics, 56% were males, 90,7% being over 50 years. Severe cases of sepsis (33/75, 44%) were associated more often with insulin-treated diabetes than non-insulin treated group (40% vs. 4%, p<0,005) probably because of multiple comorbidities associated as suggested by a high Charlson score (6,09 vs. 4,09, p<0,05). There were 64 cases with confirmed etiology and 11 cases with clinically suspected etiology. Staphylococcus aureus and Escherichia coli were the most common agents isolated, being involved in 16 (21,3%) cases each, followed by coagulase negative Staphylococci (14/18,66%), Enterococcus spp.(6/8%), group B Streptococcus (3/4%), Streptococcus pneumoniae, Enterobacter spp., Salmonella spp. (2/2,66% each), Aerococcus viridans, Streptococcus equi, Klebsiella pneumoniae, Neisseria meningitidis, Sphyngomonas paucimobilis, Pseudomonas aeruginosa, Proteus mirabilis (1/1,33%). Multiple septic disseminations occured in 17(22,6%) cases and meningeal involvment was doccumented in 10(15,6%) cases. Meticillin resistance was noted in 53,3% for invasive isolates of S. aureus. Among 16 invazive strains of E. coli, 25% were resistant to 3rd generation cephalosporins, 17% to ciprofloxacin and 6,6% to aminoglycosides and colimycin. There were no E. coli strains resistant to imipenem, piperacillin-tazobactam and aztreonam. The mean mortality rate was 14,66%. CONCLUSIONS: The high level of resistance of S. aureus and E. coli to commonly used antibiotics and meningeal involvement imposes a multidisciplinary approach of the diabetic patient. Proper knowledge of the pathogers involved in the potential invazive diseases is an important tool for successful treatment with appropriate empirical broad-spectrum antimicrobial agents.

[Cryptococcus meningitis, five years of experience and literature review]. / Meningita cu Cryptococcus spp. Cinci ani de experienta si revista literaturii.

UNLABELLED: The aim of this study was to determine the distribution and antifungal susceptibility profile of Cryptococcus spp. isolated from patients in northeast Romania. MATERIAL AND METHOD: Fungi isolated from blood and cerebrospinal fluid (CSF) cultures were identified by ID32C strips (bioMerieux, France). Susceptibility testing was performed using ATB FUNGUS2 strips (bioMerieux, France). RESULTS: A total of 20 significant strains have been isolated. Overall, Cryptococcus neoformans was the most frequent isolate (95%). We mention the first Cryptococcus albidus meningitis in Romania (strain with multiple resistance). All cryptococci tested were susceptible to amphotericin B with minimal inhibitory concentration (MIC) =1 microg/mL; 90% strains were susceptible to flucytosine. Resistance to fluconazole and itraconazole was observed in 2 and 1 case, respectively. Most of the patients had an associated infection, tuberculosis in 37.5% cases. Despite appropriate therapy 4 patients died (21%). CONCLUSION: First choice induction therapy with amphotericin B plus flucytosine followed by fluconazole is highly recommended since resistance to antifungal agents is still very low.
