Abstract

Nosocomial central nervous system infections constitute 0.4% of all nosocomial infections. The responsible pathogens of nosocomial meningitis are quite different from community-acquired meningitis with high rates of morbidity and mortality. The most important prognostic factor is the appropriate choice of pathogen-specific antibacterial therapy. In this report, a 64 years old woman with nosocomial meningitis caused by Klebsiella pneumoniae and Acinetobacter spp. after lumbar disc hernia operation, has been presented. The risk factors were detected as recent history of neurosurgical operation for three times and long term (29 days) use of external ventricular drainaige (EVD) catheter. Empirical meropenem (3 x 2 g, IV) and vancomycin (2x1 g, IV) therapy was initiated upon the diagnosis of nosocomial meningitis based on the clinical and laboratory findings on the postoperative fifth day. Extended-spectrum beta-lactamase (ESBL) producing K. pneumoniae (susceptible to amikacin, imipenem, meropenem, cefoxitine, ciprofloxacin, piperasillin-tazobactam and trimethoprim/sulfamethoxazole) was recovered from cerebrospinal fluid (CSF) and blood samples obtained on the same day. There was no change in the status of the patient on the eighth day of meropenem therapy, with high leukocyte number (1300/mm3) and presence of gram-negative bacilli in CSF, and ESBL positive K. pneumoniae (antibiotic susceptibility pattern same with the previous isolate) growth in CSF culture. Thereupon intravenous ciprofloxacin (3 x 400 mg) was added to the therapy and her EVD has been changed. However, ESBL positive K. pneumoniae (antibiotic susceptibility pattern same with the previous isolate) together with Acinetobacter spp. (susceptible to gentamycin, tobramycin, netilmicin, ciprofloxacin, levofloxacin and cefepime) were isolated from CSF and blood cultures obtained on the 13th day of meropenem and fifth day of ciprofloxacin therapy. Therefore intraventricular and intravenous gentamicin (15 mg/days and 3 x 120 mg, respectively) were added to the therapy. The patient recovered at the end of three weeks treatment without any additional sequela other than her primary illness. This case was the first case of nosocomial meningitis due to ESBL positive K. pneumoniae together with Acinetobacter spp. in the available literature.

Özet

Nozokomiyal santral sinir sistemi enfeksiyonları, tüm nozokomiyal enfeksiyonların %0.4'ünden sorumludur. Nozokomiyal menenjit etkenleri toplum kökenli menenjit etkenlerinden farklı olup, morbidite ve mortalite oranları oldukça yüksektir. Prognozu etkileyen en önemli faktör ise etkene yönelik doğru antibakteriyel tedavi seçimidir. Bu raporda, lomber disk hernisi operasyonu sonrasında, Klebsiella pneumoniae ve Acinetobacter spp.'nin birlikte etken olduğu nozokomiyal menenjit gelişen 64 yaşında bir kadın hasta sunulmaktadır. Olgunun üç kez nöroşirürjik operasyon geçirmesi ve uzun süreli (29 gün) eksternal ventriküler drenaj (EVD) kateteri olması, risk faktörleri olarak değerlendirilmiştir. Olguya, postoperatif beşinci günde klinik ve laboratuvar bulgularına dayanılarak nozokomiyal menenjit tanısı konulmuş ve ampirik olarak meropenem (3 x 2 g, IV) ve vankomisin (2 x 1 g, IV) tedavisi verilmiştir. Aynı gün alınan beyin omurilik sıvısı (BOS) ve kan kültürlerinde, genişlemiş spektrumlu beta-laktamaz (GSBL) üreten K. pneumoniae (amikasin, imipenem, meropenem, sefoksitin, siprofloksasin, piperasilin-tazobaktam ve trimetoprim/sülfametoksazole duyarlı) üremiştir. Meropenem tedavisinin sekizinci gününde hastanın kliniğinde bir değişiklik olmamış; BOS incelemesinde yüksek lökosit (1300/mm3) ve gram-negatif basil varlığı saptanmış, BOS kültüründe de GSBL pozitif K. pneumoniae (antibiyotik duyarlılığı bir önceki suş ile aynı) üremesi devam etmiştir. Buruın üzerine tedaviye siprofloksasin (3 x 400 mg, IV) eklenmiş ve EVD kateteri değiştirilmiştir. Meropenem tedavisinin on üçüncü, siprofloksasin tedavisinin beşinci gününde, BOS ve kan kültüründe GSBL pozitif K. pneumoniae (antibiyotik duyarlılığı bir önceki suş ile aynı) ve Acinetobacter spp. (gentamisin, tobramisin, netilmisin, siprofloksasin, levofloksasin ve sefepime duyarlı) üremesi nedeniyle tedaviye intraventriküler gentamisin (15 mg/gün) ve IV gentamisin (3 x 120 mg) eklenmiştir. Olgu üç haftalık intraventriküler antibiyotik tedavisi sonunda primer hastalığının sekelleri dışında yeni bir sekel gelişmeksizin iyileşmiştir. Bu olgu, GSBL pozitif K. pneumoniae ve Acinetobacter spp.'nin birlikte etken olduğu, yerli ve yabancı literatür taramalarında ulaşabildiğimiz kadarıyla ilk nozokomiyal menenjit olgusu olması nedeniyle sunulmuştur.
