Pseudotuberculosis (Yersinia): Follow-up
Updated: Sep 8, 2008
Follow-up
Further Inpatient Care
Supportive care for patients with Y pseudotuberculosis sepsis includes general hospital acute-level care (intensive medical/surgical care may be needed, although uncommon unless the patient is severely ill) and intravenous fluids, frequent monitoring, serial examinations, radiographic studies, intravenous antibiotics, and treatment of any complicating host- or disease-related factors.
Inpatient & Outpatient Medications
In outpatient settings or mild inpatient situations, vigilant observation without the use of antibiotics is reasonable. (See Complications, Prognosis.) Y pseudotuberculosis infection is often benign and self-limited.
Deterrence/Prevention
Food-borne epidemics of Y pseudotuberculosis infection can occur. Contact precautions, especially in the inpatient setting, apply to appropriate barriers (eg, gown, gloves) to exposure to enteric secretions, such as with diarrhea. Avoid ingestion of uncooked meat, contaminated water, or unpasteurized milk. Careful handwashing should follow consumption or handling of chitterlings (pork intestines).
Complications
Postinfectious sequelae may include arthritis and erythema nodosum. Additionally, severe Y pseudotuberculosis infection may be complicated by formation of coronary aneurysms, septic features associated with iron-overload states, and renal involvement with tubulointerstitial nephritis. Intussusception has also been reported in children.
Prognosis
Uncomplicated mesenteric lymphadenitis due to Y pseudotuberculosis infection is generally self-limited and commonly does not require antibiotic therapy. Septic forms of Y pseudotuberculosis infection or those associated with systemic manifestations are serious and carry a high mortality rate (often 75% despite antibiotic therapy).Patient Education
Patients with Y pseudotuberculosis infection (and their families) should be familiar with forms of exposure, routes of infection, variable manifestations of the disease, difficulties in the diagnostic issues, and the potential for associated complications, including sepsis, reactive arthritis, erythema nodosum, and rare events such as cardiac or renal sequelae.
Miscellaneous
Medicolegal Pitfalls
- Y pseudotuberculosis infection is an unusual infection, meaning that its diagnosis may be missed or delayed because of its variable presentation. In addition, because this infection has a wide variety of differential diagnoses based on which features predominate in a given patient (intestinal vs extra-intestinal), documentation and communication with the patient, family, and colleagues should be realistic and comprehensive.
- Patients with sepsis and those with complicated mesenteric adenitis syndromes should be treated promptly, and consultation with infectious diseases specialist and gastroenterologist (adult or pediatric, as indicated) is recommended.
- Because of the uncertainties involved in predicting the extent of disease and/or potential postinfectious sequelae, practitioners may opt for empirical antimicrobial therapy in patients with uncomplicated presentations. However, no significant data have shown that antibiotic therapy directly reduces the likelihood of postinfectious sequelae.
