An unusual manifestation of brucellosis: A case with multisystemic involvement and adult respiratory distress syndrome

A rare complication of brucellosis is presented. A 23-year old man was admitted to the hospital with fever, chills, fatigue, dyspnea, and rash. The patient was diagnosed as brucellosis by the isolation Brucelia melitensis (B. melitensis) from blood and cerebrospinal fluid cultures. Multisystemic involvement; pneumonia, meningitis, hepatitis, endocarditis, cutaneous lesions and hematological abnormalities were observed. Adult respiratory distress syndrome (ARDS) developed. The patient treated with a combination of ceftriaxone, doxycycline and rifampicin, was operated for mitral valve replacement. Relapse has not been observed

Comparative evaluation of in vitro activities of carbapenemes against gram-negative pathogens: Turkish data of COMPACT study [Karbapenemlerin gram-negatif patojenlere kar§i in vitro aktivitelerinin karşilaştirmali deg`erlendirmesi: COMPACT çalis§masi türkiye verisi]

PubMed ID: 21644063The aim of this study was to determine the in vitro activities of doripenem, imipenem, and meropenem against clinical gram-negative isolates. A total of 596 clinical isolates were obtained from intensive care unit (ICU) and non-ICU patients in 10 centers over Turkey between September-December 2008. The origin of the isolates was patients with nosocomial pneumonia (42.4%), bloodstream infections (%40.4), and complicated intraabdominal infections (17.1%). Of the isolates, 51.8% were obtained from ICU patients. The study isolates consisted of Pseudomonas spp. in 49.8%, Enterobacteriaceae in 40.3%, and other gram-negative agents in 9.9%. The minimum inhibitory concentrations (MIC) for doripenem, imipenem and meropenem were determined for all isolates in each center using Etest¯strips (AB Biodisk, Solna, Sweden). Of the isolates, 188 (31.5%) were resistant to at least one of the carbapenems. MIC50 of doripenem against Pseudomonas spp. was 1 mg/L which was similar to that of meropenem and two-fold lower than imipenem. Susceptibility to carbapenems in P.aeruginosa was 64% for doripenem at an MIC level of 2 mg/L, 53.9% and 63% for imipenem and meropenem at an MIC level of 4 mg/L, respectively. Doripenem and meropenem showed similar activity with the MIC 90 of 0.12 mg/L whereas imipenem was four-fold less active at 0.5 mg/L. Against other gramnegative pathogens, mostly Acinetobacter spp., MIC 50 was 8 mg/L for doripenem and 32 mg/L for other two carbapenems. P.aeruginosa isolates were inhibited 84.2% with doripenem and 72.1% with meropenem at the MIC level of 8 mg/L. Doripenem generally showed similar or slightly better activity than meropenem and better activity than imipenem against pathogens collected in this study. Against Pseudomonas spp., doripenem was the most active of the three carbapenems. Doripenem and meropenem were equally active against Enterobacteriaceae and at least four-fold more active than imi-penem. It was concluded that doripenem seemed to be a promising agent in the treatment of nosocomial pneumonia, blood stream infections and intraabdominal infections particularly in patients who were under risk of developing antimicrobial resistance.

Salmonella enterica serotypes and Salmonella infections: A multicenter study covering ten provinces in Turkey [Salmonella enterica serotipleri ve Salmonella enfeksiyonlari: Türkiye'de on ili kapsayan çok merkezli bir çalişma]

PubMed ID: 15490836In order to find the distinctive features of Salmonellae and Salmonella infections in Turkey, 620 Salmonellae strains, isolated from various clinical samples (481 stool, 108 blood, 12 urine, 3 bone marrow, 3 cerebrospinal fluid, 9 pus, and one from each of the bile, pleural fluid, wound, catheter samples) in 13 clinical microbiology laboratories of 10 provinces in Turkey (Ankara, Antalya, Bursa, Edirne, Eskişehir, İstanbul, İzmir, Kayseri, Konya and Trabzon) between July 1, 2000 and June 30, 2002, were serotyped. Among the patients 43% were female, 57% were male, 63.2% were from outpatient clinics and 36.8% were hospitalized patients. Seventy eight percent of the patients had gastroenteritis, 10.7% had septicemia/local infection, 9.8% had typhoid/ paratyphoid fever and 1.5% were carriers. Incidence of gastroenteritis was higher in 0-5 years age group (p<0.001). Of the 620 Salmonella enterica isolates, 47.7% were S.Enteritidis, 34.7% S.Typhimurium, 6% S.Paratyphi B, 2.9% S.Typhi, 0.2% S.Paratyphi A, 6.1% serogroup C1, and 2.4% serogroup C2. S.Enteritidis was the most common serotype in all provinces except for Kayseri, where S.Typhimurium was found to be the most common serotype (68.2%). Overall, the most frequently isolated serotype was S.Enteritidis, also being the most common serotype in stool and blood cultures. During the surveillance period two outbreaks have occurred, the first one by S.Enteritidis strains in Edirne, and the second one by S.Typhimurium strains in Kayseri. As a result, Salmonella infections are still a common health problem in Turkey, and active surveillance of Salmonella infections has vital importance

Epidemiology Of Penicillin Resistance In Streptococcus Pneumoniae Isolates In Kayseri, Turkey

Objective To determine the penicillin resistance and serotype distribution of Streptococcus pneumoniae strains and to identify clonal relationships of isolates resistant to penicillin by means of pulsed-field gel electrophoresis (PFGE). Methods In total, 193 S. pneumoniae strains were isolated froth clinical specimens between November 1997 and January 2000. Susceptibility testing was carried out by E test, and serotyping by the Quellung reaction. Clonal relationship was analyzed by using PFGE with smaI endonuclease. Results Of the S. pneumoniae isolates, 23% were intermediately resistant to penicillin. There were no high-level resistant pneumococci. The majority of isolates intermediately resist-ant to penicillin were of serogroups/serotypes 19, 23, 14 and 1, in descending order of frequency. There were eight major clones in strains intermediately resistant to penicillin. It was seen that serogroups in the 23-valent polysaccharide vaccine, 7-valent, 9-valent, and 11-valent vaccine formulations caused 92%, 75%, 78% and 87% of pneumococcal diseases in our region, respectively. Conclusion Penicillin resistance in S. pneumoniae is relatively uncommon in Kayseri. All vaccine formulations can prevent the majority of pneumococcal diseases, and there is genetic heterogeneity in intermediately penicillin-resistant pneumococci in this region.WoSScopu
