Toxic megacolon associated with Campylobacter jejuni colitis

A Rare Case of Caecum Perforation Secondary to Campylobacter jejuni Infection

Campylobacter is a common cause of bacterial gastroenteritis worldwide. This report presents a rare case of a 44-year-old female who developed a caecum perforation following an initial diagnosis of Campylobacter jejuni infection. The patient initially presented with several episodes of diarrhoea, vomiting, and abdominal pain. Initial investigations confirmed an uncomplicated C. jejuni infection, which was treated with antibiotics and supportive measures. Despite treatment, the patient's symptoms persisted and worsened, and caecum perforation was confirmed on the abdomen and pelvis computed tomography. The patient underwent an emergency right hemicolectomy with an end ileostomy and was discharged home on postoperative day 14 after she made a full recovery. Healthcare professionals should be vigilant for possible severe complications in patients with C. jejuni infection. Frequent abdominal examinations with radiological investigations should be considered when symptoms are worsening to promptly identify any potentially life-threatening complications similar to those in the presenting case.

Pediatric sigmoid colonic perforation with Campylobacter enterocolitis: a case report and review of the literature

BACKGROUND

Campylobacter-related infectious gastroenteritis is common and usually self-limited. Intestinal perforation is a rare complication of the infectious colitis caused by Campylobacter, and only handful of cases have been reported. This is the first published case report of pediatric Campylobacter intestinal perforation located in the sigmoid colon.

CASE PRESENTATION

A 15-year-old previously Taiwanese healthy boy presented with 5 days of fever up to 39.8 °C, with right lower quadrant abdominal pain and watery diarrhea. Although he received antimotility agents and antipyretics at a local clinic to relieve symptoms, he came to the emergency department with signs of shock manifesting as hypothermia to 35.2 °C, tachycardia, and low blood pressure. Laboratory testing demonstrated leukocytosis with left shift and significant elevation of C-reactive protein. Stool and blood cultures were obtained, and he was admitted for fluid challenge and antibiotic treatment. On the second day of admission, he suffered from sudden onset of severe, diffuse abdominal pain. Physical examination revealed muscle guarding, rebounding tenderness, and silent bowel sound. Abdominal X-ray showed subdiaphragmatic free air at standing view. The patient underwent emergent exploratory laparotomy, which revealed sigmoid colon perforation about 0.5 cm. Enterolysis and repair of sigmoid colon were performed. Intraoperative stool specimen nucleic acid amplification testing had turned positive for Campylobacter spp. with negative results for other bacterial pathogens. His symptoms improved and he tolerated food well, and was discharged 15 days after admission.

CONCLUSIONS

We present this case because of the rarity of Campylobacter-induced sigmoid colon perforation in the pediatric population. It is important to keep in mind that sigmoid colon perforation can be due to an infectious cause, and one of the culprits can be Campylobacter. Infectious colitis caused by Campylobacter spp. should be managed cautiously and the use of antimotility agents in such conditions should be considered judiciously.

Campylobacter jejuni pancolitis complicated by toxic megacolon in an immunocompetent host

This is an unusual case of a middle-aged, immunocompetent man who developed toxic megacolon (TM) secondary to infection with a normally harmless bug, Campylobacter jejuni. He presented with diarrhoea, fever and abdominal pain. Faecal cultures were positive for C. jejuni. However, the patient did not show significant improvement after a trial of intravenous antibiotics. Bowel segment dilation on a CT scan combined with systemic signs (fever) led to the diagnosis of TM. A subtotal colectomy was planned but an unexpected positive response to conservative therapy deferred the surgery. Our case emphasises the crucial role that bowel rest and good nutritional support play in treating TM of infectious aetiology and how it can help avoid the need for a life-altering subtotal colectomy and ileostomy. For such presentations we also highlight how empirical steroid therapy or diagnostic sigmoidoscopy for suspected underlying ulcerative colitis can be detrimental to patient outcomes.

Increased incidence of Campylobacter enteritis and their quinolone resistance between 2010 and 2015: Results of a French national observatory conducted in 21 general hospitals (CHG)

INTRODUCTION

In Europe, the number of cases of Campylobacter enteritis and their quinolone resistance is increasing. The aims of this work were to evaluate: (1) the hospital epidemiology of bacterial enteritis between 2010 and 2015. (2) The proportion of Campylobacter and Salmonella enteritis. (3) Resistance to quinolones in adult and paediatric populations. (4) To investigate possible regional epidemiological and bacteriological disparities.

PATIENTS AND METHODS

This is a multicentric study carried out in 21 general hospitals (CHG) representing 14 French regions with a prospective collection of the results of coprocultures from 2010 to 2015 in adult and paediatric populations (children < 15 years old not exposed to quinolones). The epidemiological and bacteriological data were collected from software laboratory for positive stool cultures for Campylobacter and Salmonella. The results were compared year by year and by a period of 2 years.

RESULTS

In adults, Campylobacter enteritis was each year significantly more frequent than Salmonella (P < 0.001), with a significant increase from 2010 to 2015 (P < 0.05). In children, there was also a significant and stable predominance of Campylobacter enteritis over the study period (P = 0.002). The quinolone resistance of Campylobacter was greater than 50% on the whole territory, with no North-South difference over the three periods studied. It increased significantly from 2012 to 2015 in adults (48% to 55%, P < 0.05) and in children (54% to 61%, P = 0.04).

CONCLUSION

Our results confirm the increase in the prevalence of Campylobacter enteritis compared to Salmonella between 2010 and 2015. The quinolone resistance of Campylobacter is greater than 50% on the whole territory, stable between 2010 and 2015 in adults and significantly increased in children.

Campylobacter colitis: Rare cause of toxic megacolon

INTRODUCTION

Campylobacter is the leading cause of bacterial diarrhoeal illness worldwide. Toxic megacolon is a rare but potentially devastating complication.

PRESENTATION OF CASE

A 55year old female with liver cirrhosis, alcoholism and hepatitis C, presented with severe colitis and stool specimen positive for Campylobacter. She developed septic shock, multi-organ dysfunction syndrome and toxic megacolon unresponsive to medical therapy, and underwent a subtotal colectomy with end ileostomy. Despite initial improvement, the patient died on postoperative day 4.

DISCUSSION

Early surgical consultation is essential as toxic megacolon may be complicated by perforation or uncontrolled bleeding; progressive colonic dilatation with clinical deterioration is also an important indication for surgery.

CONCLUSION

Toxic megacolon should be considered in a patient with Campylobacter colitis who becomes critically unwell. Despite treatment, toxic megacolon is associated with a significant risk of mortality.
