Pleuropulmonary infection due to Clostridium subterminale.

Clostridial pleuropulmonary infection in a patient with suspected pulmonary embolism is described. Clostridium subterminale was recovered as the sole pathogen on several occasions despite antibiotic therapy. The patient died of cardiac failure after a complicated course in hospital. Clostridium subterminale is a rare pathogen and has not so far been reported as the sole cause of pleuropulmonary infection.

Clostridial myonecrosis cluster among injection drug users: a molecular epidemiology investigation.

A molecular epidemiologic investigation was performed on a cluster of severe necrotizing Clostridium infections in 5 injection drug users admitted to an urban community hospital. Interviews with survivors suggested a point source of infection. Pulsed-field gel electrophoresis of SmaI restriction digests was performed to determine the molecular relatedness of clinically obtained isolates and isolates obtained from heroin samples and the home environment. A common clonal strain was found in Clostridium sordellii isolates from 2 socially unrelated patients and from drug paraphernalia. Clonality of a Clostridium perfringens strain from another patient isolate was identical to an isolate from a syringe found in her home. Other C perfringens isolates from patients, heroin, and the environment were determined to be polyclonal. We postulate that rapid recognition and public health notification led to rapid resolution of the outbreak.

Clostridium difficile infection is a risk factor for bacteremia due to vancomycin-resistant enterococci (VRE) in VRE-colonized patients with acute leukemia.

A cohort study was conducted in a cancer center to identify risk factors for bacteremia with vancomycin-resistant enterococci (VRE) in neutropenic cancer patients colonized with VRE. There were 10 patients with VRE bacteremia among 56 colonized with VRE, of whose charts 51 were available for review. One hundred percent of patients with VRE bacteremia (10 of 10) vs. 56% of patients without VRE bacteremia (23 of 41) had acute leukemia (P = .01, Fisher's exact test). Four of the 10 patients with VRE bacteremia had a positive Clostridium difficile toxin assay within 6 days of their first positive VRE blood culture. Both C. difficile infection and antimicrobial (vancomycin and ciprofloxacin) use during VRE colonization were significant risk factors for VRE bacteremia in univariate analysis. When a Cox proportional hazards model was used to account for differences in follow-up time, C. difficile infection was the only statistically significant risk factor (risk ratio, 8.2; P = .007) for VRE bacteremia in VRE-colonized patients with acute leukemia.

[Relapsing infections with Clostridium difficile].

Two women, aged 78 and 85 years, presented with watery diarrhoea and fever after a course of antibiotic therapy. Pseudo-membranous colitis was diagnosed, which was adequately treated. In both patients the C. difficile colitis relapsed, which was successfully treated with a pulse and tapering scheme of vancomycin. C. difficile infection is a frequent cause of antibiotic-associated diarrhoea. Clinical presentation can vary in severity. Cytotoxin testing, immunoassay and endoscopy are important tools in diagnosing C. difficile colitis. Like the first infection, the first relapse must be treated with metronidazole or vancomycin. To treat a second relapse, a pulse and tapering dose of vancomycin has been recommended. Nevertheless, multiple recurrences may occur, which are difficult to treat.

Secondary infection of an endometrioma following fine-needle aspiration.

A Clostridium infection occurred in an endometrioma following fine-needle aspiration. Fine-needle aspirations are clinically useful and safe. The authors conclude, however, that this procedure may rarely result in a secondary infection. Specific recommendations to avoid such complications are stated.

Clostridium difficile infection in adult hamsters.

Diarrhea was encountered in a group of adult female golden Syrian hamsters (Mesocricetus auratus) used for titrating the scrapie agent. Ninety percent of the cases occurred in animals over 210 days old even though animals of all age groups lived in the colony concurrently. The cause of diarrhea was investigated in both uninoculated animals and those receiving greater than a limiting dilution of scrapie infectivity, i.e., animals that were not expected to contract the experimental scrapie disease. Three forms of diarrhea were observed. The most commonly encountered was profuse and watery. A chronic form presented with semiformed, thin fecal material smearing the retroperitoneal region. Hemorrhagic diarrhea was observed rarely. Mortality was high among animals with acute watery or hemorrhagic diarrhea. Animals with semiformed soft stools were dehydrated, had a roughened hair-coat, and hunched back. Cardinal lesions were necrosis, inflammation, and mucosal hyperplasia of the cecum and colon and cholangiohepatitis with amyloid deposition. Diffuse renal amyloidosis was present in chronic cases. Toxigenic, cytotoxin B-positive Clostridium difficile was isolated from a majority of affected animals. Cytotoxin B was also present in cecal homogenates of diarrheic animals with C. difficile. The pathological and microbiologic findings indicated a typhlitis and colitis in adult hamsters that was associated with C. difficile infection.

Diarrhea and Clostridium difficile infection in Latin American patients with AIDS. Working Group on AIDS in Peru.

Diarrhea and wasting are among the most debilitating and deadly manifestations of AIDS, yet only limited information is available regarding the etiology, clinical consequences, and immunologic effects of infection with diarrheal agents. Peruvian AIDS patients presenting with and without diarrhea were followed prospectively to examine the relations among diarrheal pathogens, clinical presentations, CD4 lymphocyte count, weight loss, and survival. Patients with chronic diarrhea had lower CD4 lymphocyte counts (P = .001) and lost more weight (P < .001). Weight loss and a decreased CD4 lymphocyte count were associated with increased mortality (P = .011 and P = .003, respectively). Mean CD4 lymphocyte count varied significantly by diarrheal agent. Clostridium difficile was the most prevalent pathogen and was associated with significantly increased mortality before and after adjustment for coinfection, length of follow-up, CD4 lymphocyte count, and weight loss (P = .006). C. difficile may be a more important and more prevalent etiologic agent in AIDS than previously recognized and may represent a preventable cause of death in patients with immunosuppression.
