All-cause and pneumococcal pneumonia rates were highest in asthma
and chronic lung disease patients. IPD rates were highest in chronic
liver and lung disease patients. Per IPD episode, adults with chronic
conditions had slightly more hospital visits and longer length of stay
compared to healthy adults
–
0.9 vs. 0.8 visits and 7.6 vs 6.6 days
respectively, but substantially higher costs ($12,577 vs. $10,510). IPD
costs were highest in diabetics ($13,357) and heart disease patients
($12,865).
Conclusion:
Older adults with chronic conditions are at high risk of
pneumococcal disease, consume more healthcare resources and incur
greater costs.

Low rates of severe injection-site and systemic adverse events
within 7 days postvaccinationwith ZOSTAVAX
™
, a post hoc analysis
of two pivotal Phase 3 trials

Introduction:
ZOSTAVAX
™
, is a single dose live attenuated vaccine
licensed in >50 countries for the prevention of herpes zoster (HZ) and
postherpetic neuralgia (PHN) in adults
≥
50 years-of-age. The objective
of this post-hoc analysis was to determine the rates of severe injection-
site and systemic adverse events (AEs) within 7 days postvaccination
in two pivotal trials, Shingles Prevention Study (SPS) and ZOSTAVAX
™
Efficacy and Safety Trial (ZEST), utilizing current FDA Toxicity Grading
Scale.
Methods:
Injection-site (erythema, swelling, pain) and systemic AEs
were reported by the subject via vaccination report card; SPS n = 6,608;
ZEST n = 22,210. Injection-site erythema and swelling were reported
by size and/or with an intensity category. Severe injection-site and
systemic AEs were defined as incapacitating with inability to work or
do usual activity. The FDA Toxicity Grading Scale was not used in SPS
and ZESTwhich defined severe injection-site (erythema, swelling) and
fever using different scale.
Results:
Utilizing FDA Toxicity Grading Scale, severe injection site AEs
(swelling, erythema, pain) occurred in <1.2% of recipients of
ZOSTAVAX
™
within 7 days postvaccination in SPS and ZEST. Higher
rates were observed in recipients of ZOSTAVAX
™
compared to placebo
and in subjects 50
–
59 years-of-age. The most frequently reported
severe systemic AE within 7 days postvaccination was headache in
both ZOSTAVAX
™
and placebo groups (SPS 0.18% vs 0.18%; ZEST 0.48%
vs 0.38%, respectively). Other severe systemic AEs occurred in <0.2% of
subjects after ZOSTAVAX
™
administration.
Conclusions:
Severe injection-site and systemic AEs were reported
infrequently within 7 days postvaccination with ZOSTAVAX
™
in SPS
and ZEST.

Introduction:
Prolonged suppressive antibiotic therapy (PSAT) is
usually defined as an antibiotic therapy prescribed as a long-life
treatment. Data about PSATare scarce. Our objectivewas to describe its
characteristics and outcomes in PJI in elderly patients.
Methods:
Using a national retrospective multicentric study, we
analyzed epidemiological characteristics, drug indications, tolerance,
outcomes of a cohort of patients
≥
75 years old and treated with PSAT
for PJI. Event or failure was defined as withdrawal of PSAT, systemic
progression of infection under PSAT and/or death, We used a
composite binary outcome defined as the first occuring event among
these 3 previous type of events.
Results:
136 patients had a median age of 84 years {IQR 79
–
89}.
The predominant pathogens among 132 patients with identified
pathogen were staphylococcus (62.1%) (Staphylococcus aureus in
41.7%), enterobacteriacea (15.9%) and streptococcus (15.2%). Initial
intravenous (IV) antibiotic therapy was prescribed for 95 patients
(69.9%). PSAT was prescribed as immediate palliative in 30.1% of cases:
usually with betalactam, cotrimoxazole, fluoroquinolone. First-line
PSAT was stopped in 45 patients (33.1%). 24 patients died (17.6%); 2
were infection-related (8.3%). The median follow-up of patients was 16
months (range 0
–
112). The 2-year survival rate without event was 70%
(95% confidence interval [CI], 62.5
–
77.5%). Stepwise backward regres-
sion showed that variables associated with an increased risk of an
event were: monomicrobial infection (HR = 9.15, P = 0.041), a Mac Cabe
score equal to 3 (HR = 2.47, P = 0.054), PSAT given by another person
(HR = 3.39, P = 0.006), bactaeremia (HR = 2.73, P = 0.032). Initial IV
antibiotic therapy was associated with a decreased risk of treatment
failure (HR = 0.43, P = 0.006).
Conclusion:
Life-long antibiotic therapy might postpone treatment
failure and may be beneficial in selected cases, in particular in older
patients with limited life expectancy in whom surgery is limb or life-
threatening. Moreover, IV therapy may partially reduce the inoculum
size, facilitating the efficacy of oral PSAT. Large prospective multi-
centric studies, including comprehensive geriatric assessment, are
needed to confirm the place, efficacy and safety of PSAT in PJI and to
homogenize medical practice.

Getafe, Madrid, Spain
Objectives:
The main objectives of this study are to describe the
pathogens isolated in urine cultures differentiating between the sexes
in hospitalized patients over 65 years developing nosocomial urinary
tract infection, and analyze the antibiotic resistance of these
pathogens.
Methods:
Retrospective descriptive study with a sample of 1843 urine
cultures of patients admitted >65 years in the Hospital of Getafe from
2009 to 2015. Using database WASPSS Project.
Results:
Between January 2009 and December 2015 1843 urine
cultures were isolated with >100,000 CFU of patients with more
than 72 hours of admission. The isolated pathogens were Escherichia
coli 39.45%, Pseudomonas aeruginosa 15.74%, Enterococcus sp 11.39%
and 10.31% Klebsiella pneumoniae. Differentiating between sexes
Pseudomonas aeruginosa was the second most common pathogen in
men and the fourth in women. E. coli has resistance rate of 0% to
carbapenems, 5% to Fosfomycin and up to 30% to amoxicillin-
clavulanate and levofloxacin. P. aeruginosa has a rate of resistance to
carbapenems (meropenem and imipenem) of 10%, 32% to piperacillin-
tazobactam and 14% to levofloxacin. Enterococcus sp, presents
resistance rates of 0% to Nitrofurantoin, Ampicillin and Vancomycin,
and 55% to Quinolone.
Conclusions:
More frequent nosocomial infection pathogens were
related to E. coli, Pseudomonas aeruginosa and Enterococcus sp. High
rate of resistance to recommended clinical guidelines for first-line
treatment antibiotics. Emergence of resistance to broad-spectrum
antibiotics in the last seven years.
