Medical evacuation from abroad of critically ill patients: A case report and ethical issues

RATIONALE

Patients repatriated from foreign hospitals are sources of extensively drug-resistant (XDR) bacteria outbreaks. Thus, an individual benefit potential for the patient opposes a collective ecological risk potential. These ethical issues have not been well studied.

PATIENT CONCERNS

We report the case of a 74-year-old patient repatriated from Mauritius to the French island of Reunion who presented mesenteric infarction evolving over several days, and who suffered a cardiac arrest before transfer.

DIAGNOSES

In Reunion Island, a CT-scan revealed a multisegmental enlarged parietal enlargement associated with free peritoneal effusion and a suboccluded aspect of the superior mesenteric artery.

INTERVENTIONS

Surgical exploration showed a severe mesenteric infarction with peritonitis, and a resection of 120cm of the small intestine was conducted. This patient was infected with a vanA glycopeptide-resistant Enterococcus faecium and a carbapenem-resistant Klebsiella pneumoniae which produced carbapenemases NDM-1 and OXA-181, which required specific care and could have led to a local epidemic.

OUTCOMES

The patient died after 9 days after being admitted to the ICU.

LESSONS

Repatriation of critically ill patients from abroad should be considered according to ethical criteria, evaluating, if possible, the expected benefits, and ecological risks incurred. Limiting unnecessary transfers could be an effective measure to limit the spread of XDR bacteria.

[Cardiac arrest during serve Pneumocystis jiroveci infection in an immune-compromised patient after splenectomy]

BACKGROUND

Pneumocystis jiroveci (old name Pneumocystis carini) can cause severe pneumonia in immune-compromised patients, most commonly those who are HIV infected.

CASE REPORT

A 68-yr-old man, who eight years earlier had undergone trauma related splenectomy, was admitted to ITU after a cardiac arrest due to septic shock caused by unknown pathogen. He had been treated for three weeks with various antibiotics without improvement. On the second day after resuscitation, high concentration of lgM anti-Pneumocystis jivecii antibodies was found, and high-dose trimetoprim therapy was started and continued for two weeks, Further treatment was complicated by ventilator-associated pneumonia (Acinetobacter baumannii); the patient eventually recovered without any neurological sequelae, and was transferred to a low-dependency area after 4 weeks in ITU.

CONCLUSION

We conclude that Pneumocystis jiroveci infection should be suspected as a cause of severe pneumonia in splenectomised patients.

Fatal acute purulent pericarditis in a patient with renal transplant: a case report

OBJECTIVES

Acute purulent pericarditis is a lifethreatening disease, although it is becoming uncommon in the era of antibiotics.

MATERIALS AND METHODS

We present a case of fatal acute massive purulent pericarditis in a kidney transplant recipient.

RESULTS

A 46-year-old woman had an unrelated commercial renal transplant in 2003. She had a history of diabetes mellitus and hepatitis C infection. Kaposi sarcoma developed in the posttransplant period. Her last admission was prompted by the development of acute rejection confirmed by transplant biopsy, and she was treated with intravenous methylprednisolone. Three days before her death, thrombophlebitis of the right forearm was noted. We postulate that this could have been the source of the fulminant purulent pericarditis, as the organism in the pericardial fluid was Staphylococcus aureus, a common pathogen in thrombophlebitis. She was initially resuscitated after cardiac arrest but died shortly after.

CONCLUSIONS

Severe purulent pericarditis in the immunocompromised patient can occur abruptly. The source of infection may show minimal signs and symptoms. Thrombophlebitis and other apparently minor infections should not be overlooked in such patients.

Clostridium septicum aortitis causing aortic dissection in a 22-year-old man

Clostridium septicum infection is a rare cause of aortic dissection, and the mortality rate for the condition is high. Only 26 cases of C. septicum aortitis have been reported; all of those patients were elderly, and 20 of them had an associated colonic neoplasm. Herein, we present the case of a 22-year-old man whose C. septicum aortitis resulted in aortic dissection that involved the entire length of the aorta. Upon autopsy, no neoplasm or other predisposing condition was identified in this patient. To the best of our knowledge, this is the 1st report of C. septicum aortitis, fatal or otherwise, in a young individual.

Predictors of unfavorable outcomes in enterovirus 71-related cardiopulmonary failure in children

BACKGROUND

Enterovirus 71 (EV71) can sometimes cause fatal or disabling diseases in children; therefore EV71-infected children with cardiopulmonary failure were investigated at Chang Gung Children's Hospital to discover the prognostic predictors.

METHODS

We investigated 27 EV71-infected children with cardiopulmonary failure from May 2000 to September 2001 and analyzed their clinical data to find predictors associated with unfavorable outcomes of deaths or ventilator dependence.

RESULTS

Of the 27 patients, 8 (30%) died and 10 (37%) were ventilator-dependent. Troponin I levels correlated most strongly with fatality, with 5 of the 6 children with troponin I levels >40 ng/ml dying (P = 0.001). Other factors correlated with fatality were cerebrospinal fluid white blood cell count > or =100/microL (P = 0.002) and initial systolic pressure < or =100 mm Hg (P = 0.05). Of the 19 survivors, 10 (53%) were left with central hypoventilation, dysphagia and/or limb weakness plus atrophy. The factors associated with ventilator dependence included higher inotrope equivalent (P < 0.001), duration of hypotension > or =40 hours, initial blood systolic pressure < or =100 mm Hg, positive EV71 isolation and age > or =12 months.

CONCLUSIONS

Poor prognostic factors were related to cardiovascular and neurologic damage; therefore physicians may consider advanced cardiovascular support for EV71-infected children with cardiopulmonary failure.
