Proctitis

Proctitis is not a single disease but a clinical manifestation of various underlying triggers. Pathophysiologically, the inflammation is an immune response to injury, infection, or autoimmune dysfunction. Research published in the American Journal of Gastroenterology (2024) suggests that the breakdown of the mucosal barrier allows bacteria or irritants to penetrate the tissue, triggering a cascade of inflammatory cytokines.

Non-Modifiable Risk Factors

• Genetics: A family history of Crohn’s disease or ulcerative colitis increases the risk of developing ulcerative proctitis.
• Age: While it can occur at any age, IBD-related proctitis often peaks between ages 15 and 30.
• Sex/Gender: Certain infectious causes are statistically more prevalent in specific demographic groups based on sexual health practices.

Modifiable Risk Factors

• Unprotected Sexual Contact: Engaging in anal intercourse without barrier protection increases the risk of infectious proctitis.
• Radiation Therapy: Undergoing radiation for pelvic malignancies is a primary risk factor for radiation proctitis.
• Antibiotic Use: Frequent use of broad-spectrum antibiotics can disrupt gut flora, potentially leading to infections like Clostridioides difficile (C. diff) which can involve the rectum.

According to the Centers for Disease Control and Prevention (CDC, 2023), individuals with multiple sexual partners are at a higher risk for infectious proctitis. Additionally, patients treated for prostate or cervical cancer have a 5% to 20% lifetime risk of developing chronic radiation proctitis, per clinical oncology data (2024).

Prevention strategies focus on the specific cause:

• Infectious Prevention: Consistent use of condoms and regular STI screenings.
• Radiation Protection: Modern radiation techniques (like IMRT) aim to minimize exposure to healthy rectal tissue.
• IBD Management: While the onset of IBD cannot be prevented, strict adherence to maintenance therapy can prevent the progression of inflammation to the rectum.

The diagnostic journey typically begins with a primary care physician or a gastroenterologist who reviews the patient's medical history, sexual history, and recent travel or antibiotic use.

A digital rectal exam (DRE) is often performed, where the provider uses a lubricated, gloved finger to check for abnormalities, tenderness, or blood in the lower rectum.

• Proctosigmoidoscopy: A thin, flexible tube with a camera is inserted into the rectum to visualize the lining directly. This is the gold standard for diagnosis.
• Biopsy: During the endoscopy, small tissue samples are taken to be examined under a microscope. This helps distinguish between IBD, infection, and radiation damage.
• Stool Tests: Used to check for bacterial infections, parasites, or the presence of calprotectin (a marker of inflammation).
• STI Screening: Blood or swab tests for gonorrhea, chlamydia, syphilis, and herpes.
• Imaging: In complex cases, a CT or MRI may be used to assess the extent of inflammation or look for complications like fistulas (abnormal connections between tissues).

Diagnosis is confirmed when clinical symptoms (like tenesmus and bleeding) correlate with endoscopic findings of mucosal edema (swelling), erythema (redness), or ulceration, and are supported by histological (tissue) evidence from a biopsy.

Healthcare providers must rule out other conditions that mimic proctitis, including:

• Hemorrhoids (swollen veins).
• Anal fissures (small tears in the lining).
• Solitary rectal ulcer syndrome.
• Rectal cancer or polyps.
• Diverticulitis (if inflammation extends higher).

The primary goals of treatment are to reduce rectal inflammation, eliminate any underlying infection, manage pain, and achieve long-term remission (a period without symptoms).

According to the American College of Gastroenterology (ACG) guidelines (2023), the first-line treatment for ulcerative proctitis typically involves topical therapy, as this delivers the medication directly to the site of inflammation. Talk to your healthcare provider about which approach is right for you.

• Aminosalicylates (5-ASAs): These are anti-inflammatory drugs specifically designed for the digestive tract. They are often administered via suppositories or enemas for proctitis. Side effects are generally mild but can include abdominal pain or headache.
• Corticosteroids: Used for more severe inflammation or when 5-ASAs are insufficient. These work by broadly suppressing the immune response. They are usually intended for short-term use due to side effects like weight gain, mood changes, and bone density loss.
• Antibiotics and Antivirals: If the proctitis is found to be infectious, specific antimicrobial agents are used to clear the pathogen. The duration depends on the specific infection identified.
• Immunomodulators and Biologics: For chronic proctitis related to IBD that does not respond to other treatments, these classes target specific proteins in the immune system to stop the inflammatory cascade.

In cases of radiation proctitis, healthcare providers may use specialized treatments like Argon Plasma Coagulation (APC), which uses ionized gas to seal bleeding vessels, or sucralfate enemas to coat and protect the lining.

• Surgery: Rarely needed for proctitis alone, but may be considered if complications like abscesses or fistulas develop, or if the condition is part of severe, refractory ulcerative colitis.
• Fecal Microbiota Transplant (FMT): Currently being studied for certain types of inflammatory and infectious proctitis (like C. diff) to restore healthy gut bacteria.

Acute infectious proctitis may resolve in 7-14 days with treatment. Chronic IBD-related proctitis requires lifelong monitoring and maintenance therapy to prevent flares. Regular follow-up endoscopies may be required.

• Pregnancy: Many 5-ASA medications are considered safe, but corticosteroids and biologics require careful management by a specialist.
• Elderly: Older patients may be more sensitive to the side effects of steroids and are at higher risk for ischemic proctitis.

> Important: Talk to your healthcare provider about which approach is right for you.

While diet does not cause proctitis, it can significantly influence symptom severity. During a flare, a low-residue (low-fiber) diet may be recommended to reduce the frequency of bowel movements and minimize rectal irritation. Research published in the journal Nutrients (2023) suggests that avoiding caffeine, spicy foods, and high-fat dairy can help reduce tenesmus and cramping. Hydration is critical, especially if diarrhea is present.

Moderate exercise is generally encouraged to reduce stress and improve overall well-being. However, during acute flares, high-impact activities (like running) may exacerbate the urge to defecate. Walking, yoga, and swimming are often better tolerated.

Inflammation can cause systemic fatigue. Prioritizing 7-9 hours of sleep helps the body's immune system regulate inflammation. Using a heating pad on the lower abdomen may provide comfort before sleep.

Stress is a known trigger for IBD flares. Evidence-based techniques such as Mindfulness-Based Stress Reduction (MBSR) and Cognitive Behavioral Therapy (CBT) have been shown to improve the perceived quality of life in patients with chronic rectal inflammation.

• Acupuncture: Some small studies suggest it may help with pelvic pain management, though more evidence is needed.
• Omega-3 Supplements: May have mild anti-inflammatory effects, but should only be used as an adjunct to medical therapy.
• Probiotics: Certain strains may help maintain remission in ulcerative proctitis, but their use should be discussed with a gastroenterologist.

Caregivers should offer emotional support, as the condition can be embarrassing for the patient. Helping with meal preparation that adheres to dietary restrictions and providing a supportive environment for rest are vital.

The prognosis for proctitis is generally excellent when the underlying cause is identified and treated early. According to data from the Crohn's & Colitis Foundation (2024), most patients with ulcerative proctitis can achieve long-term remission with appropriate medication. Infectious proctitis typically clears completely with a standard course of antibiotics or antivirals.

If left untreated, proctitis can lead to:

• Anemia: Due to chronic blood loss.
• Ulcers: Deep sores in the rectal lining.
• Fistulas: Abnormal tunnels connecting the rectum to other organs or the skin.
• Strictures: Narrowing of the rectum due to scar tissue, making bowel movements difficult.

For those with chronic forms (IBD or radiation-induced), long-term management involves regular check-ups and adherence to maintenance medications. Patients with long-standing ulcerative proctitis may have a slightly increased risk of colorectal cancer, necessitating periodic screening colonoscopies.

Most individuals live full, active lives. Joining support groups and staying informed about new treatment options can empower patients to manage the condition effectively.

Contact your healthcare provider if you notice a return of symptoms after a period of remission, if your current treatment is causing side effects, or if you develop new symptoms like joint pain or skin rashes.
