20 Sefoperazon/sulbaktamın kanıtlanmış klinik etkinliği
Nozokomiyal sinüzit , pnömoni (pediatrik hastalar dahil) Karın içi infeksiyonlar Obstetrik/jinekolojik infeksiyonlar Üriner sistem infeksiyonları Nötropenik ateş A large number of clinical trials have demonstrated the clinical efficacy of cefoperazone/sulbactam to treat adult and pediatric infections. Comparative studies have demonstrated that the clinical efficacy of cefoperazone/sulbactam is comparable or superior to that of standard treatment options, including antibiotic combinations. As a result of this proven clinical efficacy, guidelines for the treatment of community-acquired respiratory tract infections and the treatment or prophylaxis of intra-abdominal/surgical infections have acknowledged a role for cefoperazone/sulbactam in the hospital-based management of patients with community- or hospital-acquired infections.

21 Nötropenik ateş Eşleştirmeli, prospektif, çift kör çalışma (ABD)
Kemoterapi ilişkili nötropenik ateşi olan erişkin kanser hastaları ( >16 yaş) Tedavi: Cefoperazone/sulbactam 2 g/1 g günde 3 kez IV Ceftazidime 2 g günde 3 kez IV İnfeksiyon iyileşene kadar Değerlendirme: Klinik cevap (semptom ve bulgular) Bakteriyolojik cevap Adult (age >16 years) cancer patients with chemotherapy-associated neutropenia (absolute neutrophil count of 500/mm3 confirmed or likely) and fever (38.5°C) were enrolled in a comparative, prospective, double-blind study conducted in the USA.1 Patients were randomized to treatment with cefoperazone/sulbactam 2 g/1 g three times daily or ceftazidime 2 g three times daily, administered intravenously until the resolution of infection. Ceftazidime is a well accepted single-agent therapy for neutropenic fever.2 Clinical response was evaluated after 72 h, on Day 5 and at the end of therapy and was classified as: initial response (marked improvement in signs and symptoms within 72 h), continued response (initial response maintained beyond 72 h), no response (persistence of signs and symptoms beyond 72 h) or relapse (initial response followed by reappearance of signs or symptoms).1 Bacteriologic response was based on the elimination of culturable material or the elimination of principal pathogens after therapy.

The mean durations of therapy were 8.5 days (range 1–28 days) and 9.5 days (range 1–37 days) respectively. More than two-thirds of patients in each group received norfloxican/fluconazole prophylaxis from the start of chemotherapy until resolution of neutropenia. The clinical response rate among clinically evaluable patients was similar for cefoperazone/sulbactam and ceftazidime at 72 h, on Day 2 and at the end of therapy (p>0.05 in all cases). A total of 56 isolates (of which 51 [86.4%] were Gram-positive, predominantly staphylococci and streptococci) were isolated from bacteremic patients. The pathogen eradication rate was 15/19 (78.9%) for cefoperazone/sulbactam and 13/24 (54.2%) for ceftazidime (p=0.09). The results of this study indicate that cefoperazone/sulbactam is clinically and bacteriologically as effective as ceftazidime in the treatment of fever-inducing bacterial infections in neutropenic patients.

There was no fixed treatment period. Imipenem/cilastatin is a well accepted single-agent therapy for neutropenic fever.2 Clinical response at the end of therapy was classified as improvement (disappearance of fever with clinical improvement and pathogen eradication) or failure (persistence of fever and/or pathogen requiring modification of therapy).1 Bacteriologic response at the end of therapy was assessed according to the eradication of isolates collected prior to therapy.

The median age of patients in the cefoperazone/sulbactam group was 47 years (range 16–76 years) compared with 39 (16–81) years for patients who received imipenem/cilastatin. The median duration range of therapy was 12 (3–69) days and 14 (3–50) days, respectively. For all infections, the overall clinical response rates for cefoperazone/sulbactam and imipenem/cilastatin were similar (p=0.17). The response rates for microbiologically documented infections, clinically documented infections or possible infections for the two groups were also similar. Of 78 pre-therapy isolates, 52 (66.7%) were Gram-positive organisms (the most common being viridans group streptococcus, 21 isolates).The overall eradication rate was similar for the cefoperazone/sulbactam and imipenem/cilastatin groups (p=0.37). These data demonstrate that cefoperazone/sulbactam is clinically and bacteriologically as effective as imipenem/cilastatin in the treatment of fever-inducing bacterial infections in neutropenic (granulocytopenic) patients.

Açık, prospektif, eşleştirmeli, tek merkezli çalışma(Turkiye) Erişkin febril nötroepnik hastalar Tedavi: Cefoperazone/sulbactam 2 g 2 kez günde ve amikacin günde 2 kez 500 mg IV Ceftazidime 2 g günde 3 kez ve amikacin günde 2 kez 500 mg IV Minimum tedavi süresi 7 gün Değerlendirme: Klinik cevap (teavinin başlamasından sonra 72 saat veya ateşsiz 5. gün) In an open-label, prospective, comparative, single-center study conducted in Turkey, adult febrile neutropenic patients were randomized to one of two intravenous treatments: cefoperazone/sulbactam 2 g twice daily plus amikacin 500 mg twice daily, or ceftazidime 2 g three times daily plus amikacin 500 mg twice daily.1 Each treatment was given for at least 7 days. Ceftazidime plus amikacin is a standard therapy for febile neutropenia.2 Clinical response (assessed 72 h after the start of therapy and after the fifth afebrile day) was classified as success (eradication of the pathogen, or five fever-free days without clinical findings of infection) or failure (need for alternative antibiotic therapy, death after five days’ treatment or withdrawal from treatment).1 Akan H et al. Mikrobiyol Bült 1995;29:131–5. 1. Akan H et al. A single center randomized study comparing the efficacy of sulbactam/cefoperazone and amikacin versus ceftazidim and amikacin in febrile neutropenic patients. Mikrobiyol Bült 1995;29:131–5. 2.

26 Akan H et al. Mikrobiyol Bült 1995;29:131–5.
The mean age (range) of the patients was 37 (16–64) years in the cefoperazone/ sulbactam plus amikacin group and 32 (14–69) years in the ceftazidime plus amikacin group. The most common underlying disease was acute myeloblastic leukemia (60% and 52% of patients, respectively). There was a trend towards greater clinical success with cefoperazone/sulbactam plus amikacin at both endpoints but this did not reach statistical significance (p>0.05). Therefore, these data indicate that cefoperazone/sulbactam is as clinically effective as ceftazidime when combined with amikacin in the treatment of fever-inducing bacterial infections in neutropenic patients.

Imipenem/cilastatin is an established monotherapy for neutropenic fever,2 and vancomycin was added to ensure coverage of methicillin-resistant pathogens. All agents were administered by intravenous drip infusion. Bone marrow transplant patients received imipenem/cilastatin at a lower dose (500 mg four times daily) because of expected lower tolerability in those patients. Clinical success was defined as the disappearance of all clinical and laboratory evidence of infection. Bodey G et al. Eur J Clin Microbiol Infect Dis 1996;15:625–34. 1. Bodey G et al.

A total of 369 febrile/infections episodes were clinically evaluable. The median age (range) of patients was 52 (17–84) years for the cefoperazone/sulbactam plus vancomycin group and 50 (18–79) years for the imipenem plus vancomycin group. The distribution of disease conditions was similar for the two groups except that a greater proportion of patients in the cefoperazone/sulbactam group had lymphoma or myeloma (18.6% versus 10.3%). Clinical success rates were similar for the two treatment groups. There were no significant differences in success rate between treatments in relation to documentation of infection, underlying disease, pathogens or prior antibacterial prophylaxis. The results of this study indicate that cefoperazone/sulbactam plus vancomycin is clinically and bacteriologically effective as imipenem/cilastatin plus vancomycin in the treatment of neutropenic fever.

Clinical trials involving approximately 2500 patients have reported a variety of adverse events, none of which occurs at a frequency of more than 6.2%. Most adverse events are of mild or moderate severity and are tolerated with continued treatment. The most common adverse events are: elevated liver function tests (serum glutamic–pyruvic transaminase and serum glutamic–oxaloacetic transaminase), positive direct Coombs test, diarrhea/loose stools, hypo-prothrombinemia, and transient eosinophilia. Cefoperazone/sulbactam is appropriate for administration to a wide variety of patients. Dose adjustments may be required in patients with renal and/or hepatic dysfunction, and should be used with care in pregnant women and nursing mothers.
