ENCEPHALITIS
Psnxmics, May 1961
F
ORTY-TWO PATIENTS with measlesen-cephalitis were observed at the Queens
General Hospital from 1952-1958 and at the
Long Island Jewish Hospital from
1954-1959. All survived. The cases were reviewed
to evaluate the results of treatment, with
particular emphasis on the effects of
adreno-corticotnopin (ACTH) and adrenal
corti-costeroids, and to report the status of the
patient 2 to 7 years after discharge from
the hospital.
Earlier reports indicate a mortality of 10
to 15% and sequelae in an even larger
per-centage. Tyler1 reviewed 67 eases of
mea-sles encephalitis; 10 were patients who had
hemiplegia, probably due to cerebral
vas-eular pathology rather than encephalitis,
and 3 were excluded as likely cases of toxic
eneephalopathy. Of the remaining 54, 4
died in status epilepticus at the time of the
initial illness and 1 died 8 years later; 11
had severe residua. The mortality was
ap-proximately 9% and sequelae occurred in
223%. The use of ACTH or adrenal steroids
is not mentioned.
Only a few publications deal with the
re-suits of therapy with ACTH and
corticoster-oids. Allen2 and Applebaum and Abler3
related the survival of 10 and 17 consecutive
cases, respectively, and sequelae occurred
in only 1 of the 17 cases of the latter
au-thors. Swanson4 reported 24 cases; 7
re-ceived steroids and 6 of these developed
sequelae.
CASE MATERIAL
Most of the 42 eases in the present series
were observed personally by one or both of the
authors, the remainder were treated by other
members of the staffs of the two hospitals. No
fixed regimen of therapy was employed.
Never-theless there was considerable similarity in the
treatment, both as to choice and dosage of the
drugs. Six patients received almost the identical
regimen suggested by Allen.2
CLINICAL FEATURES
The disease was characterized by
head-ache, vomiting, fever, irritability, muscular
weakness, strange behavior, transient
star-ing episodes, rolling of the eyes, diplopia
and nystagmus, hallucinations,
disorienta-tion and lethargy. These were frequently
followed by coma and convulsions. In a
few, athetosis and myelitic symptoms
(
weakness of the extremities) developed.The dominant findings upon admission
were : coma, convulsions, lethargy, athetosis,
pareses, ataxia, fever and respiratory
diffi-culties. At the time of admission, 23
pa-tients were in coma, 15 were lethargic and
30 were convulsing-indicating severe
dis-ease in most instances. No cases of
hemi-plegia or of toxic encephalitis, as described
by Tyler,1 were encountered. Encephalitis
was not encountered in any patient who had
measles modified by gamma-globulin.
The encephalitis became manifest from 1
to 7 days after appearance of the measles
rash in 41 eases and in 1 case after 10 days;
most frequently (27 out of 42) on the third,
fourth or fifth day (Table I). It is noteworthy
that in no instance did the disease occur
during the incubation or pre-eruptive phases
of measles.
More cases were observed in the years of
greater incidence of measles. The disease

May and June, the months of highest
in-cidence of measles in this area (Table II).
The encephalitis was most frequent
be-tween 5 and 10 years of age. This is in
keep-ing with the greatest incidence of measles in
our community. Only six patients were less
than 5 years of age (Table III).
There were only two Negro children in
the 42 cases. This is striking and probably
significant because of the high percentage
of Negro children admitted to the Queens
General Hospital. That the disease occurs
rarely in Negroes was also reported by
Hoyne and Slotkowski. There were 23 males
and 19 females in the present series.
Convulsions associated with measles but
not caused by encephalitis were observed
in two children; one was 6 years old and
one was 4 years old, both with
tempera-tunes over 104#{176}F(40#{176}C).Tile cerebrospinal
fluid was normal in both instances and the
measles progressed without further
cvi-dence of central nervous system disease.
Both children had Koplik spots within the
next 24 hours and thereafter experienced
uneventful uncomplicated measles. The
convulsions were considered to be due to
fever and these patients were not included
in this series.
LABORATORY DATA
The cerebrospinal fluid revealed wide
variations in the cell count and the protein
and the sugar content. In 12 patients there
were less than 20 cells in the cerebrospinal
fluid and in 24 patients, between 51 and
650 cells. Lymphocytes predominated but
in one instance 60% of 160 cells were
poly-morphonuclear. The protein content was
less than 50 mg/100 ml in 15 patients and
between 50 and 197 mg/100 ml in 27.
Sugar in the fluid ranged from 48 to 197
mg/100 ml; it was 48 to 74 in 12 and 75 to
197 mg/100 ml in 26.
Of the 12 patients with cell counts in the
cerebrospinal fluid less than 20, 11 had

vulsions and 1 was in coma. Nine were
treated with steroids, but none prior to the
first cenebrospinal spinal fluid examination;
6 developed sequelae, 2 behavior defects,
1 headaches, 1 mental deterioration, 1
epi-lepsy and 1 paresis of the lower extremities.
All of the 6 children with less than 5 cells
in the cerebnospinal fluid were admitted on
the first or second day of encephalitis; 1
with only 4 cells in the fluid developed a
behavior disturbance; 1 with 3 cells had
mental deterioration and 1 with no cells
developed epilepsy; the other 3 seemed to
recover. Of the 6 patients with cell counts
in tile eenebrospinal fluid less than 5, the
proteins were 21, 34, 12, 49, 67 and 172 mgI
100 ml. Where the fluid contained from 6
to 19 cells, the proteins were 35, 12, 197,
76, 67 and 68 mg/100 ml. Thus there was no
consistent correlation between the number
of cells and the level of protein in the
eere-brospinal fluid, on between either of these
and tile severity and outcome of the illness.
The leukocyte count in the blood and the
percentage of polymorphonuclear cells
varied widely. In 17 patients the counts were
less than 10,000/mm3, 7 had 15,000 to
20,000, and 5 had more than 20,000/mm3.
The polymorphonuelear cells ranged from
40 to 93%, most often 60 to 83%. The two
children with pneumonia and the one with
tracheostomy had high counts, but others
with leukocytosis did not manifest
bac-tenial complications.
Electnoencephalographs obtained on the
fourth to the thirtieth days of illness
re-vealed diffuse pathology in 17 of 19
pa-tients. Many whose tracings were abnormal
were free of signs on symptoms at the time.
A child with schizophrenic behavior had
abnormal tracings on several occasions, the
last being 2 months after the onset of
ill-ness. A child with myelitie signs had a
non-mal tracing, as did one other child free of
central nervous system symptoms at the
time. Of the 19 who had
eleetroeneephalo-grams, 19 were treated with adrenal
eon-ticosteniods and/or ACTH and only 2 of
these had normal tracings.
TREATMENT
Intensive nursing and medical care was
given to all patients who required it.
Twenty-eight patients were placed in
oxy-gen tents because of cyanosis, irregular
res-piration or poor peripheral circulation.
Electrolyte imbalance was corrected with
appropriate fluids given intravenously. All
but a few were given antibiotics
intrave-nously or intramuscularly on admission and
orally thereafter, during the acute phase
of the disease. The drugs were continued
after the acute phase only for patients with
complications; 32 received penicillin daily
and 6 of these were also given
ch!oram-phenical, while 5 were given tetracycline.
Tracheostomy was performed in two
in-stances because of inability to clear
pharyn-geal secretions. Adrenocortica! extract (4 to
12 ml) was administered to three patients
in collapse on admission. Convulsions were
controlled with intravenous use of
bar-biturates, usually sodium phenobarbital.
Three patients received injections of
gamma-globulin : one, 48 ml on the second
day; another, 10 ml daily for three doses
be-ginning on the second day of illness; and a
third, 12 ml on the fourth day.
Six had daily diminishing doses of ACTH
(40, 20, 10 and 5 units) and cortisone (300,
200, 150 and 100 or 75 mg on the fourth
day).
This regimen was adopted becauseof tile dosage recommended by Allen.2
5ev-era! other patients were given 25 units of
ACTH on admission and every 6 hours
thereafter for 5 to 22 doses; several received
other corticosteroids, as indicated in Table
Iv, where tile results of therapy are also
shown.
COURSE AND RESULTS
All but three patients were admitted
witilin 24 hours after onset of the
eneephal-itis; treatment was started promptly.
Seque-lae were observed in 13. There were no
deaths. Improvement and recovery were
rapid in all who seemed to recover
eom-plete!y, slower in those who had residua at

t Number of cases.
(
Table \7). Emergence from coma orleth-argy, cessation of convulsions and return of
temperature to normal occurred in most
in-stances in 24 to 72 hours after admission to
the hospital.
Of the 13 patients with sequelae on
dis-charge from the hospital, 9 were treated
with steroids and/or ACTH, 4 were not.
One child who received a single dose of 25
units of ACTH on admission continued to
have muscle spasticity after 14 days. The
inclusion of this case in the treated group
may be questioned because of the limited
amount of therapy. Of tile other 8 patients
\Vitil sequelae, who received ACTH and/on
corticosteroids in larger amounts, 3
de-veloped behavior defects, 3 mental
de-terioration, 1 schizophrenia and epilepsy
and 1 paresis of the extremities. Of the 4
patients with seque!ae, who received neither
steroids nor ACTH, 3 had behavior
dis-turbances and 1 mental deterioration.
FOLLOW-UP
Follow-up examinations were attempted
from 2 to 7 years after discharge from the
hospital. Twenty families responded; 18
children were examined and their parents
were interviewed. The parents of two other
children supplied information about their
progress. Fourteen of the children seen on
follow-up had been treated with ACTH
and/or corticosteroids, and six without
these drugs. The children were evaluated
by a group consisting of a social service
case worker, two third-year resident
pedia-tnicians and the authors. Social histories
and complete physical, neurologic and
fun-duscopie examination were performed. The
results are revealed in Table V. Several of
the patients had had psychologic and
psy-chiatnic evaluation while attending child
guidance or psychiatric clinics. Follow-up
psyehologie testing of patients, such as was
employed by Meyer and Byers6 in
pa-tients with measles encephalitis, was not
possible.
Of the steroid-treated group, 1 with
sequelae on discharge was normal at
fol-low-up, 6 with sequelae had the same or
other complications on follow-up, 1
be-lieved to he well on discharge was well
later but 5 others considered well on
dis-change developed late sequelae. Therefore,
of the 14 steroid-treated children seen at
follow-up, 7 originally had had
compliea-tions and 7 did not; at follow-up, 12
re-vealed sequelae and only 2 did not. Three
of those wilo were found to have developed
sequelae were among the six patients
treated with a regimen similar to that used
by Allen.2
Two of the non-treated patients, who
were considered normal on discharge,
de-veloped changes later; 2 of the 4 with
follow-up while the other 2 remained
affected. Thus, of the 22 non-treated
chil-dren, 4 had sequelae on discharge while 4
of the 6 seen at follow-up had evidence of
sequelae.
Sequelae observed at follow-up varied
frequently in type or severity or both from
those observed on discharge from the
hos-pital. Three patients had developed
epi-lepsy. The onset of epilepsy occurred 1
month to 23 years after discharge from the
hospital. None had family histories of
epi-lepsy. One, the child who received only
one dose of 25 units of ACTH, was
ob-served to have developed a visual deficit in
one eye, and another had a 30% hearing
loss; these changes may have been present
and missed at the time of discharge. One
patient continued to have paresis of the
lower extremities, but it was less severe
2 years after discharge from the hospital.
Seven patients had moderate to severe
emo-tional disturbance; all were under
psycho-therapy
at the time of follow-up examina-tion.One 14-year-old girl, who was first in her
class prior to encephalitis at 9 years of age,
was now at the lowest level. Two others had
considerable loss of intellectual ability. Two
were noted to have hallucinations, with
temperatures of 101#{176}to 102#{176}F;previously
this was not observed even with
tempera-tures of 104#{176}F.
DISCUSSION
The outstanding observation in this study
is the survival of 42 consecutive cases of
measles encephalitis. Except for identical
results presented by Steinhardt at a
con-ference,7 our experience is at variance with
earlier reports. Close examination of the
variables involved is therefore mandatory.
The likelihood that conditions other than
measles caused the encephalitis must be
rejected on the basis of clinical and
labora-tory evidence. All patients included in this
study presented characteristic Koplik
spots and measles rash prior to the onset
of encephalopathy. While no attempts to
isolate rubeok virus from the cerebrospinal
fluid were made, occasional efforts to
iso-late other viral agents from such fluids were
unsuccessful.
Tile pathogenesis of measles encephalitis
remains an enigma. Analysis of the
avail-able studies does not permit a definite
con-elusion. The isolation of rubeola virus from
the central nervous system in 19428 still
awaits corroboration. The failure of large
doses of gamma-globulin to alter the disease
may serve as negative evidence for this
theory as such amounts of gamma-globulin
do modify measles, even when given in tile
prodromal period. The theory that measles
activates a latent virus in tile host, which
is responsible for the brain involvement,9
has not been established. Another
hypoth-esis ascribes the observed changes in
measles encephalitis to a hypersensitivity
reaction. This theory is based on the
similar-ity of this measles complication to tile
en-cephalitides accompanying vaccinia,
van-ola and rubella,bO as well as to tile reactions
observed with rabies and pertussis vaccines.
The observations of others1’3 concerning
comparable central nervous system
involve-ment when experimental animals were
sen-sitized with homologous and heterologous
brain homogenates further support the
hy-persensitivity theory as the most likely
cx-planation.
The acceptance of this latter theory
oc-easioned tile use of adrenal steroids and
ACTH in an effort to interrupt the
sensi-tization sequence. While excellent clinical
results have been claimed by some authors,
the findings of others indicated that
conclu-sions based on a comparatively small
num-ben of patients may be misleading, e.g., 6
of 7 treated patients in Swanson’s series
developed sequelae.
Since no deaths occurred in either the
treated or the untreated cases in our series,
the effect of ACTH and steroid hormones
cannot be evaluated with respect to
stir-vival. It is not likely that the severity of the
encephalitis in the individual influenced our
decision to treat because both groups were
severly involved; 16 patients with
20 treated individuals, while 14 with
con-vulsions and 12 ill coma were among tile
untreated group of 22. Treatment with
these drugs was probably dependent on the
availability and popularity of the drugs at
the time. Thus, steroids and/or ACTH were
administered to only 2 of 19 patients from
1952 to 1954, while 18 of 23 were treated
between 1955 and 1958.
Analysis of our data concerning tile
bene-fits of tile hormone therapy seems
dis-counaging. Three of tile treated patients
with sequelae were admitted on or after
the third day of encephalitis with an
tin-avoidable delay in hormone therapy.
Treat-Iflellt ‘as initiated on the tenth day for
tile paretic patient, while the child with
prolonged spasticity and one with mental
deterioration were first seen on tile third
day of the complication. Animal
expeni-ments’ 14 suggest that in sensitization
cx-peniments irreversible changes are present
silontly after the initial symptoms of
enceph-alitis appear, and that these changes are
minimized only if ACTH on conticosteroids
are administered prior to sensitization.
Therefore it is questionable whether
de-lay in treatment with ACTH on
cortico-steroids resulted ill a loss of possible
bene-ficial effects.
The follow-up investigation revealed that
the status OIl discharge from tile hospital
was a poor indication of the patient’s
fu-tune. While 12 on possibly 13 patients with
sequelae were observed among tile entire
series of 42 on discharge from tile hospital,
16 of the 20 seen at follow-up had residua.
It is important to reiterate that few of those
with sequelae on discharge seemed veli at
the time of follow-up, while more of those
whose discharge examination indicated
complete recovery developed changes later.
Our experience offers no evidence that
we were able to reverse the central nervous
system changes. The data indicate further
that treatment with the amounts of ACTH
and adrenal hormones recorded in Table
V did not favorably influence tile course
of convalescence. In fact, it seems that
those treated with ACTH and/on steroids,
even those treated with the regimen
rec-ommended by Allen,2 fared poorly. Only
6 patients treated without ACTH or
corti-costenoids appeared for follow-up
examina-tion, and the finding of sequelae in 4 of
them suggests that more of this group
might have developed late complications.
Therefore, tile difference in the results
be-tween those treated with and those treated
without ACTH and/on corticosteroids
rnigilt have been of smaller magnitude.
Even if this is taken into account, the
over-all results of treatment raises serious doubts
as to tile advisability of the use of these
drugs in tile management of measles
en-cephalitis.
The most likely explanation for tile
sur-viva! of the patients in our series may rest
with tile intensive supl)Ortive thera)y
ac-corded to all children, treated and
un-treated alike. These included connection of
dehydration and electrolyte imbalance,
early tracheostomy to avoid respiratory
phanyngeal distress, treatment or
preven-tion of bacterial complications with
ade-quate antibiotic therapy. Oxygen
ad-ministration for cyanosis, impaired
cireula-tion or respiratory difficulty, the use of
anti-convulsant drugs ‘hen indicated, and
ade-quate nursing and medical attention are
very important.
SUMMARY AND CONCLUSIONS
The histories of 42 patients with measles
encephalitis were reviewed to evaluate tile
treatment, in particular to determine
whe-then adrenal corticostenoids or
adrenocorti-cotropin were helpful, beyond the results
with usual supportive therapy.
There were no fatalities, but 13 patients
had central nervous system sequelae on
dis-charge; 9 of these had been treated with,
and 4 without ACTH and/or corticosteroids.
Re-examination of 20 of the 42 cases 2 to
7 years after discharge from the hospital
revealed that of 14 children treated during
the acute phase of encephalitis with ACTH
and/or corticosteroids, 12 had central
nerv-oils system sequelae, while only 6 of these
dis-charge. Four of 6 untreated patients among
the 20 followed-up had central nervous
sys-tem sequelae, as compared to 4 of 22 at the
time of discharge from the hospital.
The patient’s condition on discharge from
the hospital did not accurately indicate the
future course; some sequelae became
mani-fest later, others disappeared, some became
milder and others worse.
Adrenal corticosteroids and ACTH
ad-ministered to these patients did not prevent
central nervous system complications.
The advisability of the use of these
hor-mones in the management of measles
en-cephalitis is questioned.
The survival of 42 consecutive patients
in-dicates that some fatalities ma be
pre-vented by constant supervision and
in-tensive supportive therapy.
