Definition
Inflammatory disorders of the upper
FGT
Any combination of
endometritis,
salpingitis,
tubo-ovarian abscess&
pelvic peritonitis.
ABOUBAKR ELNASHAR
Pathophysiology I. Ascending: common, from the LGT
1. Through sperm, TV, along surfaces
traveling from the cervix to the endometrium,
through the salpinx, and into the peritoneal
cavity
2. Through the lymphatic systems:
infection of the parametrium from IUCD
II. Lateral:
Rare, from infected appendix
III. Through hematogenous routes
Rare: tuberculosis
ABOUBAKR ELNASHAR
Factors associated with PID:
I. Factors related to sexual behaviour
•young age
•multiple partners
•recent new partner (within previous 3 months)
•past history of (STIs) in the patient or their partner
II. Instrumentation of the uterus / interruption of the
cervical barrier
• termination of pregnancy
• insertion of IUCD within the past 6 w
• HSG
• IVF

•Difficult:
1. No single historical, physical, or lab finding
is both sensitive & specific
Combinations of diagnostic findings to
improve sensitivity &specificity
ABOUBAKR ELNASHAR
2. Clinical Diagnosis
PPV: 65%– 90% compared with laparoscopy. a. Wide variation in S & S. b. Sym:
± No ±Subtle, mild, non specific e.g. AUB Dyspareunia VD
ABOUBAKR ELNASHAR
3. Laparoscopy:
accurate diagnosis of salpingitis
bacteriologic diagnosis.
not readily available
not easy to justify when sym are mild or vague.
not detect endometritis
might not detect subtle inflammation of FT.
ABOUBAKR ELNASHAR
Grading (Soper,1991):
Mild: erythema, edema, exudates, tubes are patent & mobile,
Moderate: purulent discharge & fixed tubes
Severe: TO abscess, pyosalpinx ABOUBAKR ELNASHAR
Hager criteria (Hager et al,1983)

3. Adnexal tenderness
ABOUBAKR ELNASHAR
•One or more of the following minimum criteria must
be present on pelvic examination to diagnose PID:
•The requirement that all 3 minimum criteria be
present before the initiation of empiric tt: insufficient
sensitivity for the diagnosis of PID.
ABOUBAKR ELNASHAR
Supportive criteria:
Improving the specificity of the minimum criteria
1. T >38.3°C,
2. Discharge: mucopurulent
3. Saline microscopy: WBC 6-10/HPF
4. ESR: elevated
5. CRP: elevated
6. laboratory documentation of NG or CT.
ABOUBAKR ELNASHAR
Specific criteria:
1. TVS or MRI showing
thickened, fluid-filled tubes with or without free pelvic
fluid or tubo-ovarian complex, or
Doppler studies suggesting pelvic infection (e.g.,
tubal hyperemia)
2. Laparoscopic abnormalities consistent with PID 3. Endometrial biopsy with histopathologic evidence of endometritis
ABOUBAKR ELNASHAR
Ovarian abscess
Pelvic abscess ABOUBAKR ELNASHAR
PID & tubo-ovarian complex
Tubo-ovarian abscess: an echo poor
septated process close to the uterus
(U).
ABOUBAKR ELNASHAR
Complications • Tuboovarian abscesses and pelvic peritonitis:
Acute lower abdominal pain and fever are usually
present.
US: confirm a pelvic abscess
CT: rule out other peritonitis.
• The Fitz-Hugh-Curtis syndrome:
Rt upper quadrant pain associated with Perihepatitis
±dominant symptom.
treatment for PID
ABOUBAKR ELNASHAR
• In pregnancy PID
Uncommon
: increase maternal and fetal morbidity
parenteral therapy effective against gonorrhoea,
chlamydia and anaerobic infections
(e.g. i.v. cefoxitin 2g three times daily plus i.v.
erythromycin 50mg/kg continuous infusion, with the
possible addition of i.v. metronidazole 500mg three
times daily)
(Evidence level III, B)
ABOUBAKR ELNASHAR
Differential Diagnosis
lower abdominal pain in a young woman:
• ectopic pregnancy
• acute appendicitis
• endometriosis
• irritable bowel syndrome
• complications of an ovarian cyst i.e. rupture,
torsion
• functional pain (pain of unknown physical origin)
ABOUBAKR ELNASHAR
Empiric treatment of PID
WHY? 1. Diagnosis is difficult
2. Delay in diagnosis & tt: inflam sequelae in upper
FGT.
3. Empiric antimicrobial tt of PID:
Not impair Diagnosis & management of other causes of
lower abd pain: ectopic pregnancy
ac appendicitis
functional pain
ABOUBAKR ELNASHAR
Recommendation
{lack of definitive clinical diagnostic criteria}
a low threshold for empirical tt of PID is
recommended (RCOG, 2003, B)
Outpatient antibiotic tt should be commenced as
soon as the diagnosis is suspected. (RCOG, 2003, A)
ABOUBAKR ELNASHAR
When? 1. Sexually active young women and other
women at risk for STDs
2. Pain: pelvic or lower abd
3. Other causes are excluded 4. Tenderness on pelvic examination (minimum criteria):
a) cervical motion OR
b) uterine OR
c) adnexal.
ABOUBAKR ELNASHAR
Treatment should be initiated as soon
as the presumptive diagnosis has been
made {prevention of long-term
sequelae}
ABOUBAKR ELNASHAR
Indication of hospitalization
1. Surgical emergencies (appendicitis) cannot
be excluded
2. Pregnant
3. No response to oral antimicrobial therapy
4. Unable to follow or tolerate an outpatient
oral regimen
5. Severe illness (N&V, or high fever)
6. Tubo-ovarian abscess.
ABOUBAKR ELNASHAR
General measures include:
• Rest is advised for those with severe disease (Evidence level C)
• If there is a possibility that the patient could be
pregnant, a pregnancy test should be
performed (Evidence level C)
• Appropriate analgesia should be provided (Evidence level C)
• Intravenous therapy is recommended for patients
with more severe clinical disease (Evidence level IV, C)
ABOUBAKR ELNASHAR
In inpatients the tt response can be monitored by changes in C
reactive protein and WBC .
In severe cases and cases with failure of the initial tt tuboovarian
abcess should be excluded by TVS, CT or MRI
All patients should be offered screening for STD (Evidence level IV, C) .
It is likely that delaying treatment increases the risk of long term
sequelae such as ectopic pregnancy, infertility and pelvic pain 15.
Because of this, and the lack of definitive diagnostic criteria, a low
threshold for empiric treatment of PID is recommended (Evidence
level IV, C).
In cases with suspected repeat PID, especially if it is of mild
severity, other causes should be sought and treated accordingly,
especially functional pain, pain originating in the ileopsoas
muscles, the pelvic floor and urinary tract (Evidence level IV, C).
ABOUBAKR ELNASHAR
Choice of treatment regime should be influenced
by the following:
• Mild and moderate cases should be treated as
outpatients with oral therapy16 (Evidence
level Ib, A).
• Intravenous therapy, when given, should be
continued until 24 hours after clinical improvement
and then switched to oral (Evidence level IV, C).
• Dosage recommendations may need to be
adjusted slightly depending on local licensing
regulations and the availability of drug formulations.
• The optimal duration of treatment is not known but
most clinical trials report a response to 10-14 days
of therapy.
• No difference in efficacy has been demonstrated
between the recommended regimens ABOUBAKR ELNASHAR
Selection of antibiotics
1. Effective against N. G&C. T. {negative endocervical screening does not rule out PID}.
The need to eradicate anaerobes has not
been determined definitively. Regimens with anaerobic activity should be considered
{a. Anaerobic bacteria have been isolated b. BV is present in many women who have PID}
2. Consider
availability
cost
patient acceptance.
3. Parenteral & oral therapy have similar
efficacy in mild or moderate PID
ABOUBAKR ELNASHAR
Recommended Parenteral Regimen A (RCOG, 2003, B)
I. Initial:
Cefotetan (Cefotan) 2 g IV/12 h
OR
Cefoxitin (Mefoxin) 2 g IV/ 6 h
PLUS Doxycycline 100 mg orally or IV*/12 h *Oral and IV administration of doxycycline provide similar bioavailability.
II. Continued
24 h after a patient improves clinically
doxycycline (100 mg twice a day) to complete 14
days ABOUBAKR ELNASHAR
Recommmended Parenteral Regimen B I. Initial
Clindamycin 900 mg IV/8 h
PLUS Gentamicin loading dose IV or IM (2 mg/kg),
followed by a maintenance dose (1.5 mg/kg)/8
h. Single daily dosing may be substituted. Although use of a single daily dose of
gentamicin has not been evaluated for the treatment of PID, it is efficacious in
analogous situations.
II. Continued:
24 h after a patient improves clinically
doxycycline 100 mg orally twice a day or
clindamycin 450 mg orally four times a day to complete a total
of 14 days of therapy.

•Bevan CD, Ridgway GL, Rothermel CD. Efficacy and safety of azithromycin as monotherapy or combined with metronidazole compared with two standard multidrug regimens for the treatment of acute PID. (J Int Med Res 2003;31:45–54).
•Azithromycin (Zithromax)
500 mg/d IV for 1 day or 2 days followed by 250 mg/d orally for a total of 7 days, alone or with Metronidazole 400 mg tds or 500 mg IV then orally for a total of 14 days.
ABOUBAKR ELNASHAR
•Rates of clinical success for Azithromycin alone: 97.1% with metronidazole: 98.1% Conclusion: Azithromycin, alone or with metronidazole, provides a shorter, simpler treatment option for the successful management of acute PID.
ABOUBAKR ELNASHAR
Recommended Regimen A (RCOG, 2003, B) Levofloxacin (levaquin) 500 mg orally once
daily for 14 days*
OR
Ofloxacin (floxin) 400 mg orally once daily
for 14 days*
WITH OR WITHOUT
Metronidazole 500 mg orally twice a day
for 14 days
ABOUBAKR ELNASHAR
Azithromycin: 250 mg daily for 7 days Plus Metronidazole: 500 mg tds for 14 d {effective against anaerobes and BV} (Bevan et al, 2003).
ABOUBAKR ELNASHAR
Surgical treatment should be
considered in severe cases or where
there is clear evidence of a pelvic
abscess (RCOG, 2003,B)
1. Hospitalization: at least 24 h
2. Laparotomy/laparoscopy:
a. division of adhesions & drainage of pelvic
abscesses.
b. adhesiolysis in cases of perihepatitis
although there is no evidence as to whether
this is superior to antibiotic therapy alone.
3. US-guided aspiration:
less invasive and may be equally effective.
ABOUBAKR ELNASHAR
Tubo-ovarian abscess:
I. Initial
II. Contiued:
Clindamycin or metronidazole with
doxycycline {more effective anaerobic
coverage}.
ABOUBAKR ELNASHAR
Management of Sex Partners •Examined and treated if they had sexual contact
with the patient during the 60 days preceding the
patient’s onset of symptoms.
{ a. Risk for reinfection of the patient
b. strong likelihood of urethral gonococcal or
chlamydial infection in the sex partner}. •With regimens effective against both of these
infections Patients should be advised to avoid unprotected intercourse until they, and their partner(s), have completed treatment and follow-up (Evidence level IV, C)
ABOUBAKR ELNASHAR
IUD •Risk of PID
confined to the first 3 w after insertion
uncommon thereafter. A Cochrane review:
Doxycycline or azithromycin (Zithromax) before
IUD insertion confers little benefit. •PID in IUD users: No evidence that IUDs should be removed
Close clinical follow-up is mandatory.
IUCD may be left in mild PID but should be
removed in severe cases (RCOG, 2003,B)
In women with an intrauterine contraceptive device (IUD) in situ, consider removing the IUD
since this may be associated with better short term improvement in symptoms and signs.
(Evidence level Ib, A)
ABOUBAKR ELNASHAR
Role of Prophylactic Antibiotics (2014)
Recommendation
Routine use of prophylactic antibiotics is not
recommended prior to IUD insertion, although it may
be used in certain high-risk situations. (I-C) Management of PID with IUD In Situ Recommendation In treating mild to moderate PID, it is not necessary to remove the IUD during treatment unless the patient requests removal or there is no clinical improvement after 72 hours of appropriate antibiotic treatment. In cases of severe PID, consideration can be given to removing the IUD after an appropriate antibiotic regimen has been started. (I-B)
ABOUBAKR ELNASHAR
HSG:
{Postoperative PID is an uncommon but
potentially serious complication.
Patients with dilated fallopian tubes are at
greater risk}.
1. Dilated fallopian tubes: 100 mg of
doxycycline twice daily for 5 d.
2. History of pelvic infection: doxycycline
before the procedure & continued if dilated
fallopian tubes are found (ACOG, 2006).
ABOUBAKR ELNASHAR
Surgical Abortion/D&C
{periabortal antibiotics had a 42% overall
decreased risk of infection}.
ACOG: antibiotic prophylaxis is effective,
regardless of risk.
Doxycycline: 100 mg orally 1 h before
procedure & 200 mg after procedure
Metronidazole: 500 mg orally twice daily
for 5 d
ABOUBAKR ELNASHAR
COC and PID
BTB: screen for C. trachomatis (RCOG, 2003,
C)
COC has been regarded as protective
against symptomatic PID.
Increased risk of CT. may mask endometritis.
Effectiveness may be reduced when
taking antibiotic
ABOUBAKR ELNASHAR
Recent data suggest that few antibiotics
(azithromycin and moxifloxacin, mainly) are
effective against Mycoplasma genitalium
ABOUBAKR ELNASHAR

PID is a polymicrobial infection of the upper genital
tract. It primarily affects young, sexually active
women.
The diagnosis is made clinically; no single test or
study is sensitive or specific enough for a definitive
diagnosis.
PID should be suspected in at-risk patients who
present with pelvic or lower abdominal pain with no
identified etiology, and who have cervical motion,
uterine, or adnexal tenderness.
Chlamydia trachomatis and Neisseria gonorrhoeae
are the most commonly; however, other
microorganisms may be involved.
ABOUBAKR ELNASHAR
The spectrum of disease ranges from
asymptomatic to life-threatening tubo-ovarian
abscess.
Patients should be treated empirically, even if they
present with few symptoms. Most women can be
treated successfully as outpatients with a single
dose of a parenteral cephalosporin plus oral
doxycycline, with or without oral metronidazole.
Delay in treatment may lead to major sequelae,
including chronic pelvic pain, ectopic pregnancy,
and infertility.
Hospitalization and parenteral treatment are
recommended if the patient is pregnant, has
human immunodeficiency virus infection, does not
respond to oral medication, or is severely ill. ABOUBAKR ELNASHAR
No single clinical finding or laboratory test is
sensitive or specific enough to definitively
diagnose PID.
Empiric antibiotic treatment should be initiated at
the time of presentation in patients with symptoms
suspicious for PID, even if the diagnosis has not
been confirmed. B
Women with mild to moderate PID may receive
outpatient oral medical treatment without
increased risk of long-term sequelae.
