COVID-19: The New Caledonia Experience.

New Caledonia is a French territory in the South Pacific Ocean. While COVID-19 is expanding over the world, the situation on our island seems controlled with a total of 18 documented cases. We report the measures implemented on our island that probably helped contain the epidemic spread.

The Presence of Acinetobacter baumannii DNA on the Skin of Homeless People and Its Relationship With Body Lice Infestation. Preliminary Results.

The presence of Acinetobacter baumannii was demonstrated in body lice, however, little is known about the mechanism of natural lice infection. In 2013 and 2014, cross-sectional one-day studies were therefore performed within two Marseille homeless shelters to assess the presence of A. baumannii DNA on human skin, blood and in body lice collected from the same homeless individuals. All 332 participants completed questionnaires, were examined for dermatologic signs, and provided four skin samples (hair, neck, armpits, and pelvic belt), blood samples and body lice (if any). We developed a new real-time PCR tool targeting the ompA/motB gene for the detection of A. baumannii for all collected samples. Blood culture was also performed. Body lice were found in 24/325 (7.4%) of subjects. We showed a prevalence of A. baumannii DNA skin-carriage in 33/305 (10.8%) of subjects. No difference was found in A. baumannii DNA prevalence according to body sites. A strong association between body lice infestation (OR = 3.07, p = 0.029) and A. baumannii DNA skin-carriage was noted. In lice, A. baumannii DNA was detected in 59/219 arthropods (26.9%). All blood cultures and real-time PCR on blood samples were negative for A. baumannii. Lice probably get infected with A. baumannii while biting through the colonized skin and likely transmit the bacteria in their feces. We found no evidence that lice facilitate the invasion of A. baumannii into the blood stream. Further investigations are needed to compare phenotypic and genotypic features of A. baumannii isolates from human skin and lice from the same individuals.

Faecal microbiota transplantation shortens the colonisation period and allows re-entry of patients carrying carbapenamase-producing bacteria into medical care facilities.

BACKGROUND: Colonisation with carbapenemase-producing Enterobacteriaceae or Acinetobacter (CPE/A) is associated with complex medical care requiring implementation of specific isolation policies and limitation of patient discharge to other medical facilities. Faecal microbiota transplantation (FMT) has been proposed in order to reduce the duration of gut colonisation. OBJECTIVES: This study investigated whether a dedicated protocol of FMT could reduce the negativation time of CPE/A intestinal carriage in patients whose medical care has been delayed due to such colonisation. METHOD: A matched case-control retrospective study between patients who received FMT treatment and those who did not among CPE/A-colonised patients addressed for initial clustering at the current institute. The study adjusted two controls per case based on sex, age, bacterial species, and carbapenemase type. The primary outcome was delay in negativation of rectal-swab cultures. RESULTS: At day 14 post FMT, 8/10 (80%) treated patients were cleared for intestinal CPE/A carriage. In the control group, 2/20 (10%) had spontaneous clearance at day 14 after CPE/A diagnosis. Faecal microbiota transplantation led patients to reduce the delay in decolonisation (median 3 days post FMT for treated patients vs. 50.5 days after the first documentation of digestive carriage for control patients) and discharge from hospital (median 19.5 days post FMT for treated patients vs. 41 for control patients). CONCLUSION: Faecal microbiota transplantation is a safe and time-saving procedure to discharge CPE/A-colonised patients from the hospital. A standardised protocol, including 5 days of antibiotic treatment, bowel cleansing and systematic indwelling devices removal, should improve protocol effectiveness.

Early Fecal Microbiota Transplantation Improves Survival in Severe Clostridium difficile Infections.

Background: Severe Clostridium difficile infections (CDIs) are associated with a high mortality rate despite medical and/or surgical treatment. Fecal microbiota transplantation (FMT) prevents recurrences, but its effect on survival has been shown only in patients with O27 ribotype CDI. Here, we investigated whether early FMT could improve survival in hospitalized CDI patients, particularly those with severe infection. Methods: We performed a retrospective cohort study between May 2013 and April 2016 at the infectious diseases department of the North University Hospital of Marseille, France. Patients received either medical treatment alone or treatment with early FMT. The primary outcome was the 3-month mortality rate. Results: A total of 111 patients were included: 66 in the FMT group and 45 in the non-FMT group. No patient underwent surgery. The O27 ribotype (odds ratio [OR], 3.64 [95% confidence interval {CI}, 1.05- 12.6], P = .04), severe CDI (OR, 9.62 [95% CI, 2.16-42.8], P = .003), and FMT (OR, 0.13 [95% CI, .04-.44], P = .001) were independent predictors of 3-month mortality. FMT improved survival in severe cases (OR, 0.08 [95% CI, .016-.34], P = .001) but not in nonsevere cases (OR, 1.07 [95% CI, .02-56.3], P = .97), independent of age, sex, comorbidities (Charlson score), and ribotype. The number of severe patients who needed to be treated to save 1 life at 3 months was 2. Conclusions: Early FMT dramatically reduces mortality and should be proposed as a first-line treatment for severe CDI. Further studies are needed to clarify complications and contraindications. Surgery should be reassessed in this context.

Smartphone text message service to foster hand hygiene compliance in health care workers.

BACKGROUND: Health care-associated infections are a major worldwide public health issue. Hand hygiene is a major component in the prevention of pathogen transmission in hospitals, and hand hygiene adherence by health care workers is low in many studies. We report an intervention using text messages as reminders and feedback to improve hand hygiene adherence. MATERIALS AND METHODS: The study is a historical comparison proof-of-concept study. Eighteen health care workers were monitored during 12 months by a radiofrequency identification system. Afterward we sent 2 types of text messages, congratulation or encouragement, and we studied the evolution of hand hygiene adherence. RESULTS: We recorded 15,723 hand hygiene opportunities, 8,973 before intervention and 6,750 during and after the intervention. Using a multilevel logistic regression analysis, we found a significant increase in hand hygiene adherence during the intervention (odds ratio, 1.68) compared with the historical period. DISCUSSION: Despite limitations due to the type of study, a text message encouraging personnel to be more vigilant is effective in increasing hand hygiene adherence in health care workers. CONCLUSIONS: Text message feedback should be incorporated into multimodal approaches for improving hand hygiene compliance.

Thigh abscess and necrotizing fasciitis following an inside-out transobturator tape intervention: a case report.

BACKGROUND: Tension-free vaginal transobturator tapes are used worldwide in the treatment of urinary incontinence in women. Very few severe complications have been described following this procedure, with no standard treatment yet established. CASE PRESENTATION: We present the case of a 36-year-old French white woman with no remarkable medical history, presenting with an abscess and necrotizing fasciitis 48 hours after an inside-out tension-free transobturator procedure. Samples were collected by guided puncture from the abscess, retrieving Staphylococcus aureus and Citrobacter koseri. CONCLUSIONS: Severe complications following this procedure are rare, although it can have the potential for significant morbidity and even mortality, which is worth highlighting. We recommend early surgical treatment in combination with broad-spectrum antibiotics and coverage for Staphylococcus aureus, which may be a causative agent.
