[Characterisation of Candida sp. isolated from patients after abdominal surgery]
Introduction:
Intraabdominal candidiasis (IAC) is the predominant type of invasive candidiasis after candidemia. The majority of epidemiological studies on Candida are focused only on bloodstream infections. Nevertheless, the role of blood cultures has limited application in patients with abdominal candidiasis. IAC, which includes peritonitis and intraabdominal abscesses, may occur in around 40% of patients following repeat gastrointestinal (GI) surgery or GI perforation.
Method:
Retrospective analysis of culture isolates of Candida sp. from clinical specimens of patients after abdominal surgery. The study period was from January 1 to October 31, 2016.
Results:
Our study of 33 patients with findings of Candida sp. from the abdominal cavity found a mortality of 15.2%, the most frequent strain being C. albicans and C. glabrata. All strains of Candida sp. were susceptible to echinocandins.
Conclusions:
Candida sp. is part of normal microbiota of the gastrointestinal tract and its isolation is often difficult to interpret. Unfortunately, the pathophysiologic importance of Candida isolation from the abdominal space is not completely clear in many clinical situations.Key words: invasive candidiasis intra-abdominal candidiasis laboratory diagnostics.
Insights
Intraabdominal candidiasis (IAC) is common after GI surgery. This study found Candida strains were susceptible to echinocandins, offering insights into invasive candidiasis treatment.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Surgical Infections
Background:
- Intraabdominal candidiasis (IAC) is a significant complication following gastrointestinal (GI) surgery or perforation.
- Epidemiological studies often overlook IAC, focusing primarily on candidemia.
- Blood cultures have limited utility in diagnosing abdominal candidiasis.
Purpose of the Study:
- To analyze Candida species isolated from the abdominal cavity in patients post-surgery.
- To determine the mortality rate associated with IAC.
- To assess the antifungal susceptibility patterns of isolated Candida strains.
Main Methods:
- Retrospective analysis of Candida isolates from clinical specimens.
- Study included patients who underwent abdominal surgery between January 1 and October 31, 2016.
- Identification of Candida species and antifungal susceptibility testing.
Main Results:
- 33 patients with intraabdominal Candida isolates were analyzed.
- The overall mortality rate was 15.2%.
- Candida albicans and Candida glabrata were the most frequent species; all isolates were susceptible to echinocandins.
Conclusions:
- The clinical significance of Candida isolation from the abdominal space requires further clarification.
- Echinocandins demonstrate in vitro efficacy against common Candida species found in IAC.
- Improved laboratory diagnostics are crucial for interpreting Candida findings in abdominal infections.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
