Jj. Stavola et Gj. Noel, EFFICACY AND SAFETY OF DAPSONE PROPHYLAXIS AGAINST PNEUMOCYSTIS-CARINII PNEUMONIA IN HUMAN IMMUNODEFICIENCY VIRUS-INFECTED CHILDREN, The Pediatric infectious disease journal, 12(8), 1993, pp. 644-647
Dapsone (4,4'-diaminodiphenylsulfone) is recommended as an alternative
agent for prophylaxis against Pneumocystis carinii in children with h
uman immunodeficiency virus infection. We reviewed our experience over
the past 100 months with 20 children (age range, 2 months to 13 years
) who received dapsone and examined the safety and efficacy of this re
gimen. Dapsone was taken for an average of 7.33 months/patient or a to
tal of 4410 days by those children in whom safety could be assessed. T
hree of the 20 patients had an adverse reaction to dapsone. One had mi
ld elevation of blood methemoglobin values (5.6%) and transient elevat
ion of serum transaminases that resolved without discontinuing drug. T
he other two developed allergic skin rashes which necessitated discont
inuation. Efficacy of dapsone in preventing P. carinii pneumonia (PCP)
was assessed in 16 children at high risk for developing PCP (defined
by CD4 counts or prior PCP infection). These 16 children took dapsone
for an average of 6.88 months and a total of 3300 days. Two of the 16
high risk children, one who had had a previous P. carinii pneumonia, d
eveloped PCP while taking dapsone. Both had CD4 counts less-than-or-eq
ual-to 200 cells/mm3 and were taking dapsone for greater-than-or-equal
-to 12 months before developing PCP. Dapsone is well-tolerated in chil
dren and appears to be as effective in preventing PCP in children with
human immunodeficiency virus infection as it is in adults.
