Patient: Mrs. Savita, 45F | USG Whole Abdomen (22/07/2026)

Summary of Findings

Diagnosis: Subacute Pelvic Inflammatory Disease (PID)

• Neisseria gonorrhoeae and Chlamydia trachomatis (~35% of cases)
• Mycoplasma genitalium
• Anaerobes, gram-negative bacteria, streptococci

Diagnostic Criteria (Clinical - CDC)

• Cervical motion tenderness
• Uterine tenderness
• Adnexal tenderness

• Oral temp >38.3°C
• Abnormal cervical/vaginal mucopurulent discharge
• WBCs on wet prep
• Elevated ESR or CRP
• Lab-confirmed N. gonorrhoeae or C. trachomatis

Ultrasound: findings include tubal hyperemia, thickened/fluid-filled tubes, free fluid in POD, or abscess. The USG here supports the diagnosis. - Goldman-Cecil Medicine

Management

Step 1 - Assess Severity

• Pregnancy
• Cannot exclude surgical emergency (appendicitis, ectopic)
• Severe illness (high fever, vomiting, inability to take oral meds)
• Tubo-ovarian abscess
• Failure of outpatient treatment

Step 2 - Antibiotic Regimen

Outpatient (Mild-to-Moderate Disease) - Recommended Regimen:

Note: Fluoroquinolones are no longer recommended as first-line treatment due to rising resistance. - Swanson's Family Medicine

Inpatient (Moderate-to-Severe Disease):

Step 3 - Additional Workup

1. Cervical/vaginal swab - NAAT (nucleic acid amplification test) for N. gonorrhoeae and C. trachomatis
2. CBC - look for leukocytosis
3. ESR, CRP - elevated in PID
4. HVS (High Vaginal Swab) culture and sensitivity
5. Beta-hCG - rule out ectopic pregnancy

Step 4 - Address Borderline Hepatomegaly

• LFTs (AST, ALT, ALP, GGT, bilirubin)
• Lipid profile - rule out fatty liver (NAFLD/MASLD)
• Blood glucose / HbA1c - metabolic syndrome
• Viral hepatitis screen (HBsAg, anti-HCV) if clinically indicated
• Note: Fitz-Hugh-Curtis syndrome (perihepatitis from PID spreading to the liver capsule) can cause right upper quadrant pain and is an important consideration when PID is present alongside liver findings.

Step 5 - Address Gaseous Oedematous Bowel Loops

• Likely secondary to pelvic inflammation/ileus
• No obstruction or perforation on USG
• Manage conservatively - oral fluids, avoid NSAIDs, reassess

Prognosis & Follow-Up

• Reassess clinically in 72 hours - if no improvement, consider hospitalization
• Long-term risk: each episode of PID carries ~10% risk of tubal occlusion/infertility; risk rises to 40% after three episodes
• Screen and treat sexual partner(s)
• Educate on barrier contraception

A recent meta-analysis (Zhang & Wang, 2025) confirms fluoroquinolone efficacy in PID but notes rising resistance - cephalosporin-based regimens remain preferred first-line.

Revised Clinical Assessment

What this means:

Management Plan (Pain-only Presentation)

1. Antibiotic Treatment (Outpatient)

This triple combination covers gonococci, chlamydia, and anaerobes - all likely organisms in PID.

2. Pain Relief

• Ibuprofen 400 mg orally three times daily with food (short course, 3-5 days) - for anti-inflammatory and analgesic effect
• Avoid if there is any concern about peptic ulcer disease - use Paracetamol 500-1000 mg TDS as alternative
• Antispasmodic (e.g., Drotaverine or Mefenamic acid) can be added for uterine/pelvic cramps

3. Supportive Care

• Pelvic rest (avoid intercourse during treatment)
• Adequate hydration and rest
• Treat sexual partner empirically (even if asymptomatic)

4. Minimum Workup (Do not delay treatment, but send these)

• Cervical/vaginal swab for NAAT (N. gonorrhoeae + C. trachomatis)
• CBC, CRP, ESR - to confirm inflammatory activity and have a baseline
• LFTs - to address the borderline hepatomegaly finding
• Urine pregnancy test - mandatory to rule out ectopic pregnancy before starting treatment

5. Review in 72 Hours

• Hospitalization for IV antibiotics
• Repeat USG or MRI pelvis to look for tubo-ovarian abscess
• Gynaecology referral

Red Flags - Return Immediately If:

• Fever develops (>38.3°C)
• Severe worsening of pain
• Vomiting begins
• Dizziness or fainting (raises concern for ectopic/internal bleeding)

Amoxicillin-Clavulanate (625mg) for PID - What You Need to Know

Short answer: It can work, but it has a significant gap

• ✅ Anaerobes
• ✅ Gram-negative bacteria
• ✅ Some streptococci
• ❌ Poor coverage for Chlamydia trachomatis (does NOT cover it)
• ❌ Unreliable coverage for N. gonorrhoeae (increasing resistance)

Practical Options (in order of preference)

The Cochrane systematic review on PID antibiotics (Savaris et al.) found azithromycin was non-inferior to doxycycline in cure rates, and in one low-bias study azithromycin was actually superior for mild-moderate PID.

Recommendation Summary

Best available option:

Ceftriaxone 500mg IM (single dose)
+ Azithromycin 500mg OD x 14 days    ← replaces Doxycycline
+ Metronidazole 400mg BD x 14 days

What You Have vs. What You Need

Immediate Practical Prescription

If you can get Azithromycin (most important):

• ✅ Chlamydia → Azithromycin
• ✅ N. gonorrhoeae → Amoxicillin-Clavulanate (partial)
• ✅ Anaerobes → Metronidazole + Clavulanate
• ✅ Gram-negatives → Amoxicillin-Clavulanate

If Azithromycin is also not available right now:

Pain Management (add alongside antibiotics)

Follow-up Instructions

• 72-hour review - pain should be improving
• If fever develops, pain worsens, or vomiting starts → refer to hospital immediately for IV antibiotics
• Complete the full 14-day course even if pain resolves early - stopping early is a common cause of treatment failure and tubal scarring
• Partner treatment is essential

Summary Prescription (Practical)

1. Azithromycin 500mg  - 1 tab OD x 14 days  ← get this today
2. Amoxyclav 625mg     - 1 tab BD x 14 days
3. Metronidazole 400mg - 1 tab BD x 14 days
4. Ibuprofen 400mg     - 1 tab TDS with food x 5 days
5. Pantoprazole 40mg   - 1 tab OD (morning) x 14 days

Final Prescription (Confirmed)

1. Ceftriaxone 500mg IM        - Single dose on Day 1 only
2. Doxycycline 100mg           - 1 tab TWICE daily x 14 days
3. Metronidazole 400mg         - 1 tab TWICE daily x 14 days
4. Ibuprofen 400mg             - 1 tab THREE times daily with food x 5 days
5. Pantoprazole 40mg           - 1 tab ONCE daily (morning) x 14 days

Coverage Achieved

Key Instructions for Patient

Review at 72 Hours

• Pain should start improving within 2-3 days
• If no improvement by Day 3 → hospital referral for IV antibiotics
• If fever, vomiting, or worsening pain at any point → go to hospital immediately

After Treatment (Important for 45F)

• Bulky uterus evaluation (rule out fibroids / adenomyosis)
• LFTs to address borderline hepatomegaly
• Lipid profile and blood sugar (NAFLD workup)

This Case: Medical Management Only ✅

When Surgery IS Required in PID

1. Tubo-ovarian Abscess (TOA) - not responding to antibiotics

• Abscess >8-9 cm or no improvement after 48-72 hours of IV antibiotics
• Procedure: Ultrasound-guided drainage or laparoscopic drainage

2. Ruptured TOA

• Surgical emergency - immediate laparotomy/laparoscopy
• Signs: sudden severe pain, peritonitis, septic shock

3. Cannot exclude Appendicitis or Ectopic Pregnancy

• Diagnostic laparoscopy to confirm/exclude

4. Recurrent PID with Chronic Sequelae

• Chronic pelvic pain from hydrosalpinx or tubal scarring
• Procedure: Laparoscopic salpingectomy or adhesiolysis (elective)

Progression Risk if Undertreated

Untreated/undertreated PID
        ↓
Tubo-ovarian Abscess (TOA)
        ↓
Rupture → Peritonitis → Sepsis
        ↓
Emergency Surgery

Bottom Line

This patient needs medicine, not surgery. Treat with the confirmed antibiotic regimen for 14 days, review at 72 hours, and refer for gynaecology follow-up after treatment. Surgery would only become relevant if she develops a tubo-ovarian abscess or does not respond to antibiotics - neither of which is the case right now.

Mrs. Savita, 45F — Treatment Summary

💊 Medicines

⚠️ Important Instructions

• Take Doxycycline with food and do not lie down for 30 minutes after
• No alcohol during Metronidazole course
• Avoid direct sunlight (Doxycycline causes photosensitivity)
• Complete full 14 days even if pain resolves early
• No intercourse during treatment
• Partner must also be treated

🔁 Review at 72 Hours

• Pain improving → continue full course
• No improvement → refer for IV antibiotics (hospital)
• Fever / vomiting / worsening pain → go to hospital immediately

🔬 Investigations to Send

• CBC, CRP, ESR
• Urine pregnancy test
• Vaginal swab - NAAT for Chlamydia & Gonorrhoea
• LFTs + Lipid profile + Blood sugar (for hepatomegaly workup)

📅 After Treatment

• Gynaecology follow-up — bulky uterus evaluation
• LFT review — borderline hepatomegaly
• No surgery required at this stage

Doxycycline — After Food ✅

Why it matters:

Correct Way to Take It:

✅ Eat food first
✅ Take Doxycycline 100mg with a FULL glass of water (200-250 ml)
✅ Stay sitting upright or standing for 30 minutes after
❌ Do NOT take lying down
❌ Do NOT take on empty stomach
❌ Do NOT take with milk alone (reduces absorption)
    — food is fine, but not milk by itself

Timing for This Patient (Twice Daily):

Keep approximately 12 hours apart for consistent blood levels.

NAB DT — ✅ Yes, This is Suitable

Good News - This is Actually Better Than Plain Doxycycline

• The Lactic Acid Bacillus (probiotic) already included in this tablet will reduce nausea, loose stools and stomach upset - common side effects of Doxycycline
• The Betacyclodextrin improves bioavailability, meaning the drug is better absorbed
• No need to separately prescribe a probiotic

How to Take NAB DT

Option 1: Dissolve in half a glass of water, stir and drink
Option 2: Swallow whole with a full glass of water

Confirmed Final Prescription (No changes needed)

Since NAB DT already contains a probiotic, no separate probiotic (like Sporlac or Econorm) is needed. ✅

Complete Blood Count

Differential Count

Immunology

Key Findings & Interpretation

1. 🔴 Anaemia - Significant Finding

2. 🔴 ESR 48 mm/hr - Elevated

• Normal for females is 0-20 mm/hr
• ESR of 48 confirms active inflammation - supports the PID diagnosis
• Will be used as a monitoring marker - should fall with treatment

3. ✅ TLC Normal - Important Reassurance

• White cell count 4600 is within normal range
• No leukocytosis = infection is not severe/systemic
• Confirms this is subacute/mild PID, not severe septic PID
• Supports outpatient management decision ✅

4. 🟡 CRP 5.51 mg/L - Borderline

• Just within normal (<6 mg/L)
• Mild inflammatory marker elevation - consistent with subacute presentation
• Repeat CRP after 2 weeks of treatment to confirm resolution

Revised Management - Add Iron Supplementation

⚠️ Do NOT take iron and Doxycycline together - iron reduces Doxycycline absorption. Space them at least 2-3 hours apart.

Morning (empty stomach): Pantoprazole 40mg
After breakfast:         Doxycycline (NAB DT) + Metronidazole
Midday:                  Iron tablet (2-3 hrs after Doxycycline)
Evening:                 Ibuprofen with food
Night (after dinner):    Doxycycline (NAB DT) + Metronidazole

Follow-up Labs After Treatment

• Repeat Hb + CBC at 6-8 weeks to confirm anaemia responding to iron
• Repeat ESR + CRP at 2 weeks to confirm PID resolving
• Peripheral smear if Hb does not improve - to confirm iron deficiency vs other cause
• Serum Ferritin if available - gold standard for iron deficiency confirmation

Iron Syrup Dose for Mrs. Savita (45F, Hb 9.0 g/dl)

Most Common Iron Syrups Available in India

Standard Adult Dose (for Hb 9.0 - moderate anaemia)

Iron syrup: 10 ml (2 teaspoons) TWICE daily
→ Once in the afternoon (2-3 hrs after morning Doxycycline)
→ Once at bedtime (2-3 hrs after night Doxycycline)

Duration: 3 months

How to Take Iron Syrup

• ✅ Take on empty stomach or between meals for best absorption
• ✅ Mix with or follow with a small glass of orange juice - Vitamin C doubles iron absorption
• ❌ Do NOT take with tea, coffee or milk - reduces absorption
• ❌ Do NOT take within 2-3 hours of Doxycycline
• 🟤 Stools will turn dark/black - this is normal, not blood

Expected Response

Repeat Hb at 6-8 weeks to confirm response. If Hb not improving, check Serum Ferritin and peripheral smear.
