Haemophilus influenzae is a rarely reported cause of peritonitis in chronic ambulatory peritoneal dialysis (CAPD) patients. In this report, a peritonitis case due to H. influenzae in a 32-years-old female patient with end-stage renal failure receiving CAPD for 7 years, has been reported. The patient was admitted to our clinic with the complaints of nausea, vomiting, abdominal pain, and cloudy dialysate. She had diffuse abdominal tenderness, however, other systems and peritoneal catheter exit site were found to be normal in physical examination. White blood cell (WBC) count in peritoneal fluid was 1.500/mm3 with 90% neutrophils. Gram stain of the peritoneal fluid yielded moderate number of polymorphonuclear leucocytes but no microorganism. Empirical antibiotic therapy with vancomycin and amikacin was initiated intraperitoneally. Peritoneal fluid and blood cultures were performed using BacT/ALERT (bioMerieux, NC, USA) blood culture system. Although no growth was detected in the blood sample at the end of the 5 days, growth was observed in the peritoneal sample within 48 hours. Gram staining of the positive bottle revealed gram-negative coccobacilli. At the end of an overnight incubation period, the colonies, which grew on chocolate agar, were identified as H. influenzae by using API NH system (bioMerieux, NC, USA). The isolate was found to be beta-lactamase-negative. The antibiotic regimen was switched to cephazoline 2 g/day intraperitoneally. The patient rapidly recovered and the WBC count of the peritoneal effluent decreased to 70/mm3. The therapy was continued for 21 days and she was discharged. The peritoneal catheter was not removed. During 7 months after the therapy, peritonitis did not recur. In conclusion, H. influenzae should be kept in mind as a cause of peritonitis in CAPD patients even though it is an unusual agent and the infection may be successfully treated with intraperitoneal antibiotics without removal of peritoneal dialysis catheter.

Aerococcus viridans is a gram-positive, catalase and oxidase negative, microaerophylic and non-motile coccus which is rarely associated with human infections such as endocarditis, meningitis, artritis and bacteremia. We report a case of bacteremia due to A. viridans in a 61-years-old man with malignant gall bladder neoplasm. The patient underwent a surgical operation and on the 5th day of operation he had severe abdominal pain, vomiting, high fever and discharge from operation site. He was transferred to intensive care unit and blood cultures were obtained. Piperacillin-tazobactam was initiated as empirical therapy. Blood cultures performed in Bactec system (Becton Dickinson, USA) yielded catalase negative, gram-positive cocci in tetrads. The isolate was pyrrolidonyl aminopeptidase (PYR) positive and produced alfa-hemolysis on sheep blood agar. These cocci were identified as A. viridans by Vitek 2 Compact System (BioMerieux, France) and identification was confirmed by using mini API System (BioMerieux, France). Antibiotic susceptibility testing performed with Kirby-Bauer disk diffusion method revealed that the isolate was susceptible to trimethoprim-sulfamethoxazole, tigecycline and vancomycin and resistant to penicillin, ampicillin, piperacillin-tazobactam, ceftriaxone, erythromycin, clindamycin and amikacin. The patient was successfully treated with vancomycin (2 x 1 g/day) and completely recovered without complication. In conclusion, A. viridans should be suspected as an opportunistic pathogen in immunocompromised patients and these patients should be treated according to the antibiotic susceptibility test results.

Meningococcal infections may develop as episodic or endemic cases particularly among children attending day-care centers, boarding schools or among military personnel. Bivalent (A/C) meningococcal vaccine is applied to all new military stuff since 1993 in Turkey. In this report two cases of meningococcemia and meningitis, developed in two soldiers vaccinated with meningococcal vaccine, were presented. The first case was a 21 years old male patient who was admitted to the emergency service with the complaints of high fever, headache, fatigue and vomiting. He was conscious, cooperative and oriented with normal neurological findings. Maculopapular exanthems were detected at the lower extremities. The patient was hospitalized with the initial diagnosis of sepsis or meningococcemia and empirical treatment was initiated with ceftriaxone and dexamethasone. Cerebrospinal fluid (CSF) examination yielded 10 cells/mm3 (lymphocytes) with normal CSF biochemical parameters. A few hours later skin rashes spread over the body rapidly, the symptoms got worse, confusion, disorientation and disorientation developed, and the patient died due to cardiac and respiratory arrest at the seventh hour of his admission. The second case was also a 21 years old male patient who was admitted to the hospital with the complaints of fever, headache, painful urination, confusion and agitation. He was initially diagnosed as acute bacterial meningitis due to clinical (stiff neck, positive Kernig and Brudzinsky signs) and CSF (8000 cells/mm3; 80% polymorphonuclear leukocytes, increased protein and decreased glucose levels) findings. Empirical antibiotic therapy with ceftriaxone was initiated and continued for 14 days. The patient was discharged with complete cure and no complication was detected in his follow-up visit after two months. The first case had an history of vaccination with bivalent (A/C) meningococcal vaccine three months ago and the second case had been vaccinated one month ago. The bacteria isolated from the blood culture of the first case and the CFS culture of the second case, were identified as Neisseria meningitidis by conventional and API NH system (BioMerieux, France). The isolates were serogrouped as W135 by slide agglutination method (Difco, USA), and both were found to be susceptible to penicillin and ceftriaxone. As far as the last decade's literature and these two cases were considered, it might be concluded that N.meningitidis W135 strains which were not included in the current bivalent meningococcal vaccine, gained endemic potential in Turkey. Since N.meningitidis W135 strains may lead to serious diseases, vaccination of the risk population with the conjugate tetravalent meningococcal vaccine (A/C/Y/W135) should be taken into consideration in Turkey.

Brevundimonas vesicularis has rarely been isolated from clinical specimens. We report here a case of B. vesicularis bacteremia in a female infant who presented with fever, vomiting and altered sensorium. USG abdomen showed mild hepatomegaly, moderate ascitis with bilateral mild basal pleural effusion. Blood culture was processed by BACTEC BD. Isolate was identified as B. vesicularis, by API ID 32 GN automated system. We have come across only one report of neonatal sepsis caused by B. vesicularis from India. To the best of our knowledge, this is one of the rare case reports of B. vesicularis bacteremia in a female infant.

Porphyrias, particularly acute intermittent porphyria (AIP), are rare disorders which could be associated with systemic lupus erythematosus (SLE). Although the association with AIP has been known since 1952, only 11 cases have been published to date. It is widely known that precipitating causes such as infections, hormonal changes, sunlight exposure, stress and drugs could provoke an AIP crisis. Hydroxychloroquine (HCQ) is usually used in lupus patients, but rarely appears to trigger AIP crises even in SLE patients. The case of a 51-year-old man in whom AIP onset was probably due to hydroxychloroquine use during SLE management is presented. SLE onset was accompanied by fever, pleural, lung and joint involvement with a characteristic SLE autoantibody panel. Although prednisone was given, the joint symptoms did not subside. HCQ was then started; however, some days later the patient suffered anxiety, vomiting and severe abdominal pain refractory to pain-relief drugs and liver function had worsened. No cutaneous lesions were observed. The patient suffered similar episodes accompanied by paralytic ileus and dark-coloured urine, the sediment of which showed no abnormalities. In addition, no myoglobinuria was found. This finding raised the suspicion of AIP and urine tests revealed elevated values of delta-aminolevulinic acid and porphobilinogen. Hydroxychloroquine was preventively suspended and the patient improved notably within a few days. In the following months, the patient suffered no relapse and the prednisone dose could be lowered. Finally, a review of the literature on this topic highlighted the exceptional nature of an API/ SLE association particularly in men. Interestingly, porphyria may present first followed by SLE, or vice versa. The latency period between drug administration and disease onset varies from days to 2 years. Both chloroquine and HCQ may induce PAI in SLE patients. Clinicians should be alerted to a possible association with AIP when a patient with SLE recently put on HCQ presents acute onset of abdominal and/or neurological symptoms and dark urine. Appropriate tests and prompt HCQ cessation are mandatory.
