Abstract. The effectiveness of sulfamethoxazole Key Words

and the combination of both (39 patients) in therapy Sulfamethoxazole
for acute urinary tract infections after major gynecol­ Combination

tions of TMP and SMZ were measured on the 1st Urinary tract infections
and 5th days of treatment before as well as 4, 7 and
12 h after administering the drugs. No difference was found between TMP and
TMP/SMZ, although there are minor differences in the antibacterial spectrum.
Treatment with TMP alone is superior to the combined regimen due to a smaller in­
cidence of side effects; thus, in addition to the combination with SMZ, introduction
of TMP alone on the market is recommended.
In a previous paper [28] we reported on comparative studies on the
antibacterial action of trimethoprim (TMP), sulfamethoxazole (SMZ),
and their combination (TMP/SMZ) in vitro. We concluded that TMP
alone is often as effective as its combination with SMZ. Other investiga­
tors found that the efficacy of TMP was equal to the combination of
TMP/SMZ in acute urinary tract infections [26, 27].
The combined administration of two chemotherapeutics is only recom­
mended for a few specified reasons: for example, to enlarge the antibac­
terial spectrum, to intensify antibacterial activity, or to prevent chemoresistance. But the combination may at the same time increase the frequency

of adverse reactions. Therefore, it has to be shown under what conditions
the combination is superior to the single components.
This paper reports on the results of the treatment with TMP, SMZ,
and their combination in acute urinary tract infections occurring after ma­
jor gynecological operations. The plasma concentrations of the two com­
pounds were estimated routinely in all patients in order to make sure that
the drugs were present at effective levels.

Patients. 75 women, ranging from 32 to 77 years, who suffered from acute uri­
nary tract infection after gynecological surgery were treated. Table I gives the types
of operation preceding investigation of urinary tract infection treatment. No patient
had a history of former urinary tract infection.
Diagnosis of acute urinary tract infection. Diagnosis was based on history (uri­
nary frequency, burning on urination, and continual urge to void), leukocyte count
of noncentrifuged urine in counting chamber, and bacteriological examination. Pa­
tients were catheterized routinely on the day before and 5 days after surgery. If
there were major complaints, postoperative catheterization was performed earlier.
Bacteriological cultures from the urine samples were inoculated within 4 h after
catheterization. The bacterial count was determined semiquantitatively by spreading
0.01 ml urine evenly on a sheep-blood agar plate and by counting the colonies after
18 h of incubation at 37 °C [28].
Therapy and clinical observation. Therapy was initiated only after the results of
bacteriological, chemical (i.e. total protein content of serum, electrophoresis, and
creatinine) and microscopic data (e.g. leukocytes and erythrocytes in urine) were ob­
tained.
Depending on the results of the bacteriological tests, either TMP or SMZ alone
or TMP/SMZ were given. The individual doses of the compounds were as follows:
SMZ: 2 X 3 tablets daily, each tablet containing 400 mg SMZ; TMP: 2 X 3 tablets
daily, each tablet containing 80 mg TMP; TMP/SMZ: 2 X 3 tablets daily, each tab­
let containing 400 mg SMZ and 80 mg TMP. The tablets were administered at
8 a.m. and 8 p.m.; 13 patients were treated with SMZ, 23 with TMP, and 39 with
TMP/SMZ.1
To check treatment, urine samples were studied microscopically and bacteriologically before onset of the antibacterial treatment. This occurred on the 5th day of
treatment and 2-4 weeks after the end of treatment. On the 1st and 5th days of
treatment, urine was collected during a 24-hour period to determine the excretion
of TMP and SMZ. Serum protein, electrophoresis, and serum creatinine were
checked once between the 1st and 5th days of treatment. Blood examinations for
leukocytes, erythrocytes and thrombocytes were performed before, during, and after
the course of treatment.
To measure TMP and SMZ concentrations in plasma, 10 ml of blood were col­
lected on the 1st and 5th days of treatment at 8 a.m., 11 a.m., 3 p.m., and 8 p.m.

Immediately after collection, the samples were centrifuged. In the morning and at
night the samples were obtained directly before applying the drugs.
The treatment was withdrawn if the bacteriological examination on the 5th day
resulted in ‘no growth’ and the patients were free of complaints. In no case did the
period of medication last longer than 10 days.
Determination of TMP and SMZ concentrations in plasma and urine. TMP con­
centrations were quantitated according to Schwartz et al. [31]. Total sulfonamide
was analyzed by the Bratton-Marshall reaction as suggested by R ieder [36]. All de­
terminations were done in triplicate. Statistical analysis followed standard proce­
dures (Student test) [37]. Success of therapy was assumed if the examination was
negative 2-4 weeks after the end of antibacterial treatment.

The clinical results after treatment with TMP, SMZ, or TMP/SMZ are
presented in table II. The side effects that were observed in the course of
treatment are reported in table III. Additional side effects were observed
in only one patient of the TMP group, who suffered from an acute, re­
versible leukopenia.
The concentrations of TMP and SMZ, as observed at various times on
days 1 and 5 of treatment, are presented in table IV. The average sulfon­
amide concentrations on the 1st day of treatment were significantly higher
with SMZ alone than with TMP/SMZ (11a.m.: p<0.1; 3 and 8 p.m.:
p<0.0125).

On the 5th day of treatment, total sulfonamide concentrations after
combined therapy with TMP were significantly higher than after applica­
tion of SMZ alone (8 a.m. and 8 p.m.: p<0.0125; 11a.m. and 3 p.m.:
0.0125<p<0.025).
The highest levels of total sulfonamide were observed at 3 p.m. on day
1 of treatment and at 11 a.m. on day 5. The highest levels of TMP were
found at 11 a.m. on both days 1 and 5 of therapy. The TMP concentra­
tions on the 1st day of medication were almost identical in patients treat­
ed with TMP alone or with TMP/SMZ.
On the 5th day of treatment TMP levels after administration of TMP
alone were significantly higher than after combined therapy with SMZ
(8 a.m.: p<0.05; 11 a.m.: 0.0005<p<0.0025; 3 p.m.: 0.0125<p<0.025;
8 p.m.: 0.025<p<0.05). The levels of TMP and SMZ in urine were even
higher than in plasma.

Based on the results of bacteriological examination and sensitivity
tests, no difference in the therapeutical effectiveness of the three treat­
ments was observed in our study. Similar results have been reported by
other investigators [26, 27J. The one failure in the SMZ group was due to
an error in interpretation of isolated bacteria in the agar diffusion test. In
the TMP group there was one case of chronical pyelonephritis which had
not been recognized prior to surgery; this patient was not treated long
enough to allow a final judgement on effectiveness. In the TMP/SMZ
group there were two therapeutical failures. One was due to a re-infection
with a different bacterium; the other patient was suffering from subchronical pyelonephritis which was not treated sufficiently. Further treatment
of this case also proved to be rather difficult.
Combination of Both in Acute Urinary Tract Infection

According to our measurements, the recommended standard doses
lead to fully effective plasma concentrations of the single compounds: the
lowest plasma concentration of TMP observed in the course of this study
was 0.9 jUg/ml with a mean value of 2.3 ±0.9 .«g/ml 12 h after repeated
administration. The lowest plasma concentration of total sulfonamide was
52 /rg/ml with a mean value of 75.1 ± 17.7 ;tg/ml 12 h after repeated
administration. Sensitivity of bacteria towards TMP and SMZ was as­
sumed if the minimal inhibiting concentration was less than 0.75 and
12.5 /tg/ml, respectively.
Concentrations of the two compounds are even higher in urine [8,
32-34], According to our results, the biological half-life of SMZ is
13.2 h, that of TMP 9.2 h. Schwartz and R ieder [32] reported a mean
biological TMP half-life of 8.6 h. The difference in mean plasma concen­
trations of SMZ after single and combined administrations are obscure.
Patients receiving TMP alone had considerably less complaints than
patients taking SMZ or TMP/SMZ. These include gastrointestinal dis­
turbances as well as allergic exanthemas. The frequency of gastrointestin­
al distress was high in all groups, because patients were few after surgery,
and the drugs were given before meals. One additional adverse reaction
after treatment with TMP alone was found in one patient, i.e. a reversi­
ble, acute leukopenia. Allergic exanthemas, as appearing in the SMZ
groups, were reported with similar frequency by other investigators [27,
35], Exanthemas have not yet been observed after administration of TMP
alone.
According to the results reported here and elsewhere in the literature
[26, 27], TMP is equally effective alone as in combination with SMZ
when treating acute urinary tract infection, although a synergism has been
reported in treating chronic pyelonephritis, gonorrhea, and in animal ex­
periments [4-7, 9-16, 20, 22, 26].
Considering the frequency of adverse reactions, therapy of acute uri­
nary tract infections with TMP alone is superior to the combined regi­
men. Introduction on the market of a TMP preparation for treatment of
acute urinary tract infections is therefore desirable.
