c) THROMBOXANE INHIBITION IMPROVES RENAL PERFUSION AND
EXCRETORY FUNCTION IN SEVERE CONGESTIVE HEART FAILURE
Sergio Castellani, Rita Paniccia, Claudia Di Serio, et al
Journal of the American College of Cardiology, July 2, 2003, Vol. 4, No. 1, pp.
133-139
BACKGROUND
The renal formation of the vasoconstrictor thromboxane A
2
(TxA
2
)
is increased during cardiac failure.
OBJECTIVES
The aim of this study was to evaluate whether thromboxane
inhibition
can beneficially affect renal perfusion and clinical conditions
in patients
affected by severe heart failure.
METHODS
By oral administration of picotamide we blocked renal
TxA
2
.
Fourteen patients were studied according to a randomized, double-blinded,
cross-
over design.
RESULTS
Daily 24-hour total urinary thromboxane decreased at the end of
picotamide treatment. Compared with placebo, effective renal perfusion
and the
glomerular filtration rate increased. In all patients,
picotamide treatment was
associated with an increase in diuresis. Patients also showed improvement
in
several clinical parameters, including a significant decrease
in both pulmonary and
venous pressure.
CONCLUSIONS
These results indicate that renal thromboxane formation plays
an important role in renal vascular resistance in patients with
severe heart failure.
Inhibition of TxA
2
improves kidney
function and beneficially affects indexes of
cardiac performance.

35B
BACKGROUND
Antibiotics are widely administered to children for preventing
urinary tract infection, but relevant placebo-controlled trials regarding efficacy are
lacking.
OBJECTIVES
This study examined whether low-dose, continuous oral antibiotic
therapy prevents urinary tract infection in children.
DESIGNED
A randomized, placebo-controlled study.
36B
METHODS
We randomly assigned children under the age of 18 years with
urinary tract infections to receive either daily trimethoprim–sulfamethoxazole
suspension (as 2 mg of trimethoprim plus 10 mg of sulfamethoxazole per kilogram
52
of body weight) or placebo for 12 months. The primary outcome was
microbiologically confirmed symptomatic urinary tract infection.
37B
RESULTS
From December 1998 to March 2007, a total of 576 children
underwent randomization. During the study, urinary tract infection developed in 36
of 288 patients (13%) in the group receiving trimethoprim–sulfamethoxazole
(antibiotic group) and in 55 of 288 patients (19%) in the placebo group.
38B
CONCLUSIONS
Long-term, low-dose trimethoprim–sulfamethoxazole was
associated with a decreased number of urinary tract infections in children.

HELICOBACTER PYLORI–NEGATIVE DUODENAL ULCERS:
PREVALENCE, CLINICAL CHARACTERISTICS, AND PROGNOSIS—
RESULTS FROM A RANDOMIZED TRIAL WITH 2-YEAR FOLLOW-UP
Peter Bytzer, Peter Stubbe
The American Journal of Gastroenterology
, 2001, Vol. 96, pp.1409–1416
45B
OBJECTIVE
The proportion of
Helicobacter pylori
–negative duodenal ulcer
disease appears to be increasing. Data on clinical outcome and prognosis in this
subgroup are lacking.
DESIGN
A blinded, randomised study
.
55
46B
METHODS
276 randomly selected duodenal ulcer patients were studied. Patients
were followed up for a total of 2 years. Endoscopies for assessment of ulcer relapse
were done at 6 and 12 months.
H. pylori
status was assessed. Study staff were
blinded to
H. pylori
results.
47B
RESULTS
Thirty-two (12%) patients were H. pylori-negative at entry. Only 28%
of the H. pylori–negative patients completed the study, as compared with 40% of
H. pylori–positive patients. The main reasons for the poorer prognosis in H.
pylori–negative patients were relapse of ulcer/ulcer not healed (35% vs 26%) and
relapse of severe dyspepsia symptoms without ulcer relapse (16% vs 7%). H.
pylori–negative patients randomized to eradication therapy left the study early
compared with H. pylori–negative patients randomized to long-term omeprazole
therapy.
48B
CONCLUSIONS
Clinical outcome over 2 year is significantly poorer in H.
pylori–negative patients, especially if treated with eradication therapy. These
results suggest that H. pylori infection should be assessed in all duodenal ulcer
patients before treatment is decided.

CONTEXT
Autoimmune pancreatitis (AIP) is a chronic inflammatory condition
of the pancreas constituting 1/4th of all resections performed for benign conditions
in North America.
OBJECTIVE
To review the clinical and characteristic histologic patterns of this
disease and discuss the extrapancreatic manifestations of AIP.
DESIGN
We searched the literature using MEDLINE, related conference
abstracts, and bibliographies of selected studies.
RESULTS
Autoimmune pancreatitis generally affects elderly individuals,
frequently presenting as obstructive jaundice and occasionally in association with
other autoimmune diseases. The disease can involve the bile ducts, gallbladder,
and kidney and can form inflammatory masses in the lungs. A prepancreatectomy
diagnosis can be made using a combination of clinical findings, elevated
immunoglobulin G4 levels, endoscopic fine-needle aspiration biopsy, and response
to steroids.
CONCLUSIONS
Despite significant evolution in our understanding of AIP, a
prepancreatectomy diagnosis remains a problem in the North American population.
