An 81-year-old woman with a history of temporal lobe epilepsy-induced psychotic episodes was initially admitted to a general hospital where she was started on a course of oral antibiotics for community-acquired pneumonia, and ciprofloxacin eye drops to treat nasolacrimal duct obstruction. After one week, the patient was discharged back to a nursing home with these medications. However, she was admitted to our psychiatric ward two days later due to a relapse of psychosis. Another six days later, she developed breakthrough seizures associated with subtherapeutic serum phenytoin levels. Having explored all possible causes of reduced serum phenytoin levels, ciprofloxacin eye drops was discontinued in the patient, resulting in gradual return of phenytoin levels to the therapeutic range, with no further seizures observed in the patient.

TNF-alpha mediated apoptosis of the hematopoietic cells has been thought to contribute to the ineffective hematopoiesis observed in myelodysplastic syndrome (MDS). The combination of pentoxifylline (P) and ciprofloxacin (C) has been shown to reduce the serum levels of TNF-alpha, and an earlier trial of P and C with dexamethasone (D) provided good palliation for patients with MDS. The purpose of this study is to assess the hematologic response to PCD therapy for patients suffering with MDS. 21 of 25 patients who completed at least of 12 weeks of treatment were evaluable for the treatment efficacy. At baseline, the patient's median age was 60 yr (range: 18-75 yr). The diagnoses according to WHO classification included: RA (n=5), RCMD (n=10), RARS (n=1), RCMD/RS (n=1), RAEB (3), and CMML (n=1). 11 patients (52%) had at least single lineage response. 3 patients (11%) showed improvement of triple lineage cytopenia. There were no differences in the response rates between the FAB subtypes. The median time to response was 4 weeks (range: 2-12 weeks), and it is interesting that 9 of 11 patients who had a response remained without relapse for a median of 177 days (range: 78-634 days). These preliminary results indicate that anti-cytokine therapy with PCD is an effective and well tolerated palliative treatment for patients with MDS.

BACKGROUNDA prior study showed significant antibiotic resistance to quinolone in our population. In this study we aimed to evaluate and compare the efficacy of a single versus a combined prophylactic antibiotic regimen before transrectal ultrasound-guided prostate biopsy (TRUGPB).

METHODSA prospective randomized study was conducted at a university hospital. Patients undergoing TRUGPB were randomized into an amoxicillin-clavulanate alone (1 mg; one dose before and two doses after biopsy) or an amoxicillin-clavulanate + ciprofloxacin group (250 mg; one dose before and two doses after biopsy). Patients were surveyed for infection symptoms by phone on days 3 and 30 after TRUGPB. We defined an infective complication as the occurrence of symptoms including fever, chills or rigor within 30 days after prostate biopsy, requiring medical treatment or hospitalization, aided by a territory-wide electronic medical record system.

RESULTSBetween November 2007 and July 2009, 367 patients were randomized to either amoxicillin-clavulanate alone or amoxicillin-clavulanate + ciprofloxacin group. The infection rates after TRUGPB were 3.91% in the former group (7 out of 179 patients) versus 0.53% (1 out of 188 patients) in the latter. Sixty-three percent (5/8) of patients with infective complications needed hospitalization. There was no intensive care unit admission or mortality during the study period.

CONCLUSIONSCombining prophylactic antibiotics with amoxicillin-clavulanate + ciprofloxacin significantly reduced the incidence of infective complications after TRUGPB. We recommended a combination regimen, especially in centre with high incidence of post-TRUGPB infection.

BACKGROUND/AIMS: Ciprofloxacin is considered to be a safe and effective treatment for acute infectious colitis. However, this drug may cause drug-induced pancreatitis, albeit rarely. METHODS: From March 2007 to February 2012, we studied 227 patients who were hospitalized for infectious colitis at St. Mary's Hospital. All of the patients received ciprofloxacin therapy for the treatment of infectious colitis. We observed a few cases of rare adverse events, including ciprofloxacin-induced acute pancreatitis diagnosed based on the Naranjo algorithm. RESULTS: During ciprofloxacin therapy, seven of 227 patients (3.1%) developed rare pancreatitis as defined by the Naranjo algorithm; pancreatic enzyme activity was sporadically elevated with ciprofloxacin use. After ciprofloxacin administration, the average interval until the development of pancreatitis was 5.5 days (range, 4 to 7 days). On abdominal computed tomography, pancreatic swelling and homogenous enhancement was noted in three of seven patients. Complicating acute pancreatitis was gradually but completely resolved after cessation of ciprofloxacin administration. The mean recovery time was 11.3 days (range, 8 to 15 days). CONCLUSIONS: We observed that ciprofloxacin-induced pancreatitis may occur with an incidence of approximately 3%. Ciprofloxacin-induced pancreatitis presents a short latency, suggesting an idiosyncratic hypersensitivity reaction. Practitioners should be aware that drug-induced pancreatitis can occur during ciprofloxacin therapy.

Drug-induced hypersensitivity pneumonitis results from interactions between pharmacologic agents and the human immune system. We describe a 54-year-old man with hypersensitivity pneumonitis caused by cephalosporins with identical R1 side chains. The patient, who complained of cough with sputum, was prescribed ceftriaxone and clarithromycin at a local clinic. The following day, he complained of dyspnea, and chest X-ray revealed worsening of inflammation. Upon admission to our hospital, antibiotics were changed to cefepime with levofloxacin, but his pneumonia appeared to progress. Changing antibiotics to meropenem with ciprofloxacin improved his symptoms and radiologic findings. Antibiotics were de-escalated to ceftazidime with levofloxacin, and his condition improved. During later treatment, he was mistakenly prescribed cefotaxime, which led to nausea, vomiting, dyspnea and fever, and indications of pneumonitis on chest X-ray. We performed bronchoalveolar lavage, and the findings included lymphocytosis (23%), eosinophilia (17%), and a low cluster of differentiation (CD) 4 to CD8 ratio (0.1), informing a diagnosis of drug-induced pneumonitis. After a medication change, his symptoms improved and he was discharged. One year later, he was hospitalized for acute respiratory distress syndrome following treatment with ceftriaxone and aminoglycosides for an upper respiratory tract infection. After steroid therapy, he recovered completely. In this patient, hypersensitivity reaction in the lungs was caused by ceftriaxone, cefotaxime, and cefepime, but not by ceftazidime, indicating that the patient's hypersensitivity pneumonitis was to the common R1 side chain of the cephalosporins.
