Risk factors for nosocomial bacteremia in a large Spanish teaching hospital: a case-control study.

OBJECTIVE: Identify independent risk factors associated with the development of nosocomial bacteremia. DESIGN: Exploratory, unmatched, case-control study. SETTING: A 970-bed Spanish university hospital. PATIENTS: All non-neutropenic adult patients with nosocomial bacteremia admitted during a 12-month period were eligible as cases. All adult non-neutropenic patients without nosocomial bacteremia were eligible as controls. RESULTS: The incidence of bacteremia in the study population was 6.9/1000 admissions/year. One hundred eighty cases and 180 controls were analyzed. Multivariate analysis (stepwise logistic regression techniques) identified seven risk factors independently associated with nosocomial bacteremia: age above 65 years; prior admission (within six months) to the hospital; underlying diseases that were ultimately or rapidly fatal; indwelling urethral catheter in place for more than three days; intravenous central lines or peripheral venous lines (if in place for more than four days); "high-risk surgery" (i.e., lower abdominal, cardiac or thoracic); and admission to an intensive care unit. CONCLUSIONS: Although five variables are not modifiable, the remaining two relate to the use and duration of devices. Our data give strong support for the value of testing strict guidelines for limiting vascular catheters and evaluating the need for prolonged urethral catheterization. If effective infection control measures are identified, we could target hospital-wide surveillance to patients whose risk factors are amenable to intervention.

[Severe leptospirosis. Description of a series of 10 cases].

Clinical aspects of 10 consecutive patients hospitalized for acute human leptospirosis, confirmed by serology using the microscopic agglutination test (MAT), between 1975 and 1988 in a 1000 beds Teaching Hospital are retrospectively analyzed. All of them were male, mean age of 55, presenting a suggestive epidemiological data to be at risk for Leptospira infection. Leptospira icterohaemorrhagiae was responsible for 8 cases and Leptospira canicola for 2. 7 patients were treated, after 3-4 days of admittance, with penicillin. 5 patients died. Cause of death was gastrointestinal haemorrhage in 3 and cardiogenic shock in 2. We discuss the clinical, biochemical, pathological and therapeutic aspects of the acute human leptospirosis.

[Acute enteritis caused by Salmonella: effect of mecillinam and cotrimoxazole on the clinical course and fecal carrier state].

In a prospective randomized study we have evaluated the influence of co-trimoxazole and mecillinam on the clinical outcome and the fecal Salmonella sp carrier status in 134 adult patients with acute non-typhi Salmonella sp enteritis. The patients were distributed in three groups on the basis of predefined clinical and biological criteria, depending on their risk of bacteremia or severe complications of it, or on the enteroinvasive character of the causative organism. The inclusion in any group determined the treatment. Seventy-six patients received mecillinam (1.200 mg/day p.o.), 36 co-trimoxazole (1.600 mg/day p.o.), both during five days, and 22 only diet. The patients were investigated after 1, 3 and 6 weeks until stool culture was negative. The isolated Salmonella strains, either in stool or blood culture, had a sensitivity of 98.3% to mecillinam and 96.9% to cotrimoxazole. Resistance did not develop during therapy. All patients had a favorable outcome, including the six with bacteremia. No differences were found regarding clinical features (diarrhea, abdominal pain, fever) or the rate of positive stool cultures in the three therapeutic groups in any of the follow-up controls. It was concluded that the administration of mecillinam or co-trimoxazole to patients with Salmonella sp enteritis is not associated with a prolongation of the state of fecal carrier or with the development of resistant strains.

[Treatment of atypical pneumonia with josamycin].

In the present study the clinical efficacy and tolerance of josamycin (1 g every 12 hours) was prospectively evaluated for the empirical therapy of patients below 70 years with community acquired pneumonia of atypical presentation (AP), without respiratory failure, radiological cavitation or risk factors of pharyngeal colonization by gram-negative bacilli. During a 28-month period 168 patients adequate for the study were included. The etiological diagnosis was established in 56 cases (33.3%); in 55 by seroconversion (28 Mycoplasma pneumoniae, 22 Legionella pneumophila, 1 Chlamydia psittaci and 4 Coxiella burnetii) and in only one case by positive blood culture (Streptococcus pneumoniae). The mean duration of therapy was 9 days and that of fever 1.4 days. Five patients (3%) had mild transient gastrointestinal complaints. No patient required a change of therapy. Relapses were not observed in the 45 days of follow up. In conclusion, josamycin (1 g/12 h p.o.) is an effective and well tolerated antibiotic for the therapy of pneumonia by M. pneumoniae or L. pneumophila, and it represents a good empirical treatment of AP in patients below 70 years without risk factors of GNB infection, respiratory failure or radiological cavitation.
