Overview
Typhlitis occurs in neutropenic patients undergoing treatment for a malignancy, most frequently patients with acute leukemia who are receiving chemotherapy. It has also been reported in patients with aplastic anemia, lymphoma, or acquired immunodeficiency syndrome and after kidney transplantation. Typhlitis is characterized by edema and inflammation of the cecum, the ascending colon, and sometimes the terminal ileum. The inflammation can be so severe that transmural necrosis, perforation, and death can result. The mechanism of the condition is not known, but it is probably due to a combination of ischemia, infection (especially with cytomegalovirus), mucosal hemorrhage, and perhaps neoplastic infiltration. Treatment consists of bowel rest, total parenteral nutrition, antibiotics, and aggressive fluid and electrolyte replacement.

In [year], [diagnostic test/therapy] was developed by [scientist] to treat/diagnose [disease name].
Classification
There is no established system for the classification of typhlitis.
Pathophysiology
- The exact pathogenesis of neutropenic enterocolitis is not fully understood.
- Intestinal mucosal damage, neutropenia, and the immunocompromised status of the afflicted patients appear to be the key factors in disease initiation.
- Intestinal edema, engorged veins, and a disturbed mucosal surface result from these early circumstances, making the mucosa more prone to bacterial intramural invasion.
- The intestinal motility is affected by the distension and necrosis caused directly by chemotherapeutic agents.
- Superimposed infections caused by bacteria,fungi and viruses can also disrupts the already damaged mucosa leading further intestinal edema,distension and necrosis of intestinal layer which lead to intestinal perforation.[1]
- Gram-negative rods, gram-positive cocci, enterococci, fungi, and viruses have all been blamed for the outbreak.[2][3]

Causes in Alphabetical Order
Differentiating Typhlitis from other Diseases
Typhlitis must be distinguished from other diseases characterized by fever, abdominal pain, and diarrhea. Before diagnosing this condition, some diseases with similar clinical manifestations should be ruled out.
- Clostridium difficile infection[4]
- Cytomegalovirus colitis[5]
- Norovirus infection[6]
- Graft versus host disease[7]
- Acute appendicitis[8]
- Ischemic colitis[9]
Epidemiology and Demographics
The prevalence of neutropenic enterocolitis varies between studies. Gorschlüter et al. conducted a systematic review and found that the incidence rate from 21 studies was 5.3 percent in patients hospitalized for hematological malignancies, high-dose chemotherapy for solid tumors, or aplastic anemia. Another cohort study discovered it in 3.5% of 317 severely neutropenic patients. The prevalence of neutropenic enterocolitis has been increasing in tandem with the increased use of chemotherapy, especially the agents known for causing mucositis.[10][11]
Patients with hematologic malignancies are more likely to develop neutropenic enterocolitis as a result of their underlying malignancy as well as their treatment regimens. Neutropenic enterocolitis has also been reported in patients taking immunosuppressive medications, patients diagnosed with solid tumors and autoimmune conditions.[12]
Risk Factors
Common risk factors in the development of typhlitis include hematological, solid tumors, neutropenic and Immunocompromised individuals.[13]
Screening
There is insufficient evidence to recommend routine screening for neutropenic enterocolitis.
Natural History, Complications, and Prognosis
Common complications of neutropenic enterocolitis include perforation, peritonitis, sepsis, and abscess formation, which are all caused by the pathology (bowel wall inflammation). Other risks are related to pancytopenia include thrombocytopenia-related extreme bleeding and delayed healing.
Diagnosis
Neutropenic enterocolitis is typically diagnosed based on a combination of clinical and radiologic findings.
Diagnostic Study of Choice
There are no established criteria for the diagnosis of Typhlitis.
History and Symptoms
The most common symptoms of typhlitis include fever, abdominal pain, and diarrhea. In severe cases, diarrhea can be bloody. Abdominal distension and paralytic ileus may also ocur in patients.
Physical Examination
Common physical examination of patients with neutropenic enterocolitis is usually remarkable for Abdominal discomfort which can be diffuse or localized, with the right lower quadrant being the most common location. A rigid abdomen could be an indication of bowel perforation.[14]
Laboratory Findings??
There are no diagnostic laboratory findings associated with Typhlitis. (neutropenia, thrombocytopenia or coagulopathy)
Electrocardiogram
There are no ECG findings associated with Typhlitis
Echocardiography
There are no echocardiography associated with neutropenic colitis.
CT Abdomen
- A computed tomography (CT) scan of the abdomen may be helpful in the diagnosis of neutropenic enterocolitis. Findings on CT scan suggestive of neutropenic enterocolitis include
- Intestinal wall thickening, mesenteric stranding, intestinal dilatation, pneumatosis, distention and circumferential thickening of the cecal wall.[15]
Other Imaging Findings/Ultrasound Abdomen
Ultrasound (US) may be helpful in the diagnosis of neutropenic enterocolitis. Findings on an ultrasound suggestive of neutropenic enterocolitis include circumferential wall thickening and prominent submucosa .[16]
Life Threatening Causes
Life-threatening causes include conditions such as pneumatosis, pneumoperitoneum, and pericolic fluid collections is important because they indicate a need for urgent surgical management
Treatment
Medical Therapy
- The mainstay of treatment for neutropenic enterocolitis consists of both supportive therapy and antimicrobials
- Supportive therapy for Neutropenic colitis include bowel rest with nasogastric suction, intravenous fluids, and, if necessary, parenteral nutrition.
- Empiric therapy for neutropenic colitis depends on antimicrobial exposure, bacteremia and local resistance pattern.
- Pipericillin-tazobactum, carbapenam, or an antipseudomonal cephalosporin is recommended among patients who develop neutropenic colitis and vancomycin is considered in case of mucositis is suspected, which is against gram positive bacteria.[17][18]
Surgery
- All individuals with Neutropenic enterocolitis should seek surgical advice as soon as possible.
- Surgery is usually reserved for patients with either bowel perforation, pneumoperitoneum, or persistent gastrointestinal bleeding[19].
