TREATMENT
OF
LEPROSY

Susana V. Caseria, MD

What is MDT?
• Multi-Drug Therapy (MDT) is the
accepted standard treatment for
leprosy.
• It is a combination of two (2) or
more anti-leprosy drugs:
• Dapsone • Ofloxacin
• Rifampicin • Minocycline
• Clofazimine

PB Blister Pack PB Blister Pack
(Adult) (Child)

MB Blister Pack MB Blister Pack
(Adult) (Child)

SIDE EFFECTS:

Rifampicin:
• May cause slightly reddish discoloration
of urine within a few hours after intake.
• Patient may experience body malaise,
joint and muscle pains.

SIDE EFFECTS:

Clofazimine:
• Gastric irritation.
• Skin discoloration
(disappears a few months
after stopping treatment).

SIDE EFFECTS:

Clofazimine:
• Gastric irritation.
• Skin discoloration
(disappears a few months
after stopping treatment).
• Dryness of skin.

SIDE EFFECTS:

Dapsone:
• Side effects are rare.
• Some patients may develop allergic
reactions causing itchy skin rashes and
exfoliative dermatitis.
• Patients who are allergic to any of the
sulfa drugs should not be given Dapsone.

SIDE EFFECTS
DAPSONE
 Hemolytic anemia – most common
G6PD deficiency
 Psychosis
 DDS Syndrome - 1st 6 weeks
 Fever
 Exfoliative dermatitis
 Hepatitis
 Cholestatic jaundice
 splenomegaly
 lymphadenopathy

FLUOROQUINOLONES
 Inhibit DNA gyrase
 Basically vs. gram (-) bacteria
 In vivo & in vitro activity of Ofloxacin against M.leprae (Saito,et
al, 1986)
 3 commercial derivatives tested in mouse footpad system
(Grosset, et al)
-Ciprofloxacin was inactive
-Pefloxacin had bactericidal activity at
150mg/KBNW/day
-Ofloxacin at 50 mg/KBW/day had the same effect
-Ofloxacin at 1500 mg/KBW/day had profound killing
activity

SIDE EFFECTS:

Ofloxacin:
• Well absorbed, reaches peak serum
concentration after 2 hours.
• May cause nausea, diarrhea, headache,
dizziness and insomnia.

MINOCYCLINE
 Activity of minocycline in M. leprae infected
mice ( Dr. Gelber, 1987)
 Clinical trial of minocycline in lepromatous
leprosy (Dr. Gelber et al)
- 8 untreated lepromatous pts
- 100 OD X 3 mos.
- all were negative after 3 months
- clearance :faster than dapsone &,
clofazimine, slower than rifampicin &
similar to pefloxacin, ofloxacin

SIDE EFFECTS:

Minocycline:
• Has significant bactericidal activity
against M. leprae.
• May cause discoloration of teeth in
children, occasional pigmentation of the
skin, gastro-intestinal disturbance and
dizziness.

CONTRA-INDICATIONS TO MDT:
• Cases with severe liver and kidney
disease.
• Severe hypersensitivity to any of the
MDT drugs.
• Severe anemia.
• Ofloxacin & Minocycline are not
recommended for use in pregnant women
and children below five (5) years old.

TREATMENT

 Leprosy can now be treated at home
 Health Education is an integral part of
treatment
 To be effective, treatment should be
adequate, regular and continuous

TREAT CORRECTLY THEN STOP
TREATMENT
 Always treat with full doses

 Never reduce the dose

 If complications arise, may use a different
drug

THE MAJOR PROBLEM IN
LEPROSY CONTROL
IS
PATIENT COMPLIANCE
Use every means to gain patient’s
cooperation, so that they will take
treatment as long as necessary

PATIENT EDUCATION:
The success of MDT treatment is the
joint responsibility of the doctor and the
leprosy patient.
Please educate your patient about the
importance of treatment compliance and give
corresponding instructions or advice.

TREATMENT COMPLETION:
Treatment is completed when:
• A PB patient has taken 6 MDT blister
packs within 6-9 months.
• An MB patient has taken 12 MDT blister
packs within 12-18 months.
• An SLPB patient has taken the single
dose of ROM.

Remember: A leprosy
case who has completed a
full course of treatment
i
should no longer be regarded as a
leprosy patient.

TREATMENT COMPLETION:
Upon completion of treatment:
• Remind the patient about the early signs
of a leprosy reaction.
• Teach him the early signs of a relapse.
• Encourage him to continue self-care of
the eyes, hands and feet to prevent
injuries that may lead to deformities.

DEFAULTERS:
A defaulter is a patient who has started
treatment but who has not collected his
MDT drugs for six (6) consecutive months.
It is, however, important that adequate
efforts are made to trace these patients and
persuade them to return for assessment and
re-treatment.

A defaulter who returns
for re-treatment should
be given a new course of
i
MDT.

PATIENTS WITH SPECIAL NEEDS:
Accompanied MDT:
Sometimes, patients have to interrupt
their treatment for one reason or another:
• Poor access to the health service;
• No one is at the Health Center when they
come to collect their blister packs;
• Nature of work (e.g. fisherman);
• Insurgency.

Accompanied MDT:
With Accompanied MDT, they are given
the first dose at the Health Center, and
allowed to bring home the remaining blister
packs to complete the treatment at home.

Accompanied MDT:
The treatment procedure is taught to the
patient and, if possible, a home companion.
They are then instructed to report to the
Health Center if problems occur or when
treatment is completed.

Pregnancy:
The standard regimens are considered
safe for both the mother and child.
If a woman becomes pregnant during the
course of treatment, continue MDT.
However, if a woman is 1-3 months
pregnant, wait until the 2nd trimester before
starting MDT.

Tuberculosis:
Patients suffering from both leprosy and
tuberculosis require appropriate anti-TB
therapy in addition to MDT.

Tuberculosis:
Since Rifampicin doses for TB are larger
than those in MDT, remove the Rifampicin
capsules from the MDT blister packs for the
duration of the TB therapy.
Give the Clofazimine and Dapsone
together with the TB regimen.
When the TB treatment is completed,
resume the prescribed MDT regimen.

HIV Infection:
The management of a leprosy patient
infected with HIV is the same as with any
other leprosy patient.
Information available so far indicate that
their response to MDT is the same.
The management, including treatment of
reactions, does not require modifications.

Relapse:
Relapse is the recurrence of leprosy after
the successful completion of treatment.
It is characterized by the occurrence of
new lesions.

Relapse:
The probability of relapse after MDT is
very rare.
It is often confused with reactions which
can also occur after cure.
A Morphological Index is highly
recommended when there is suspicion of a
relapse.
