Recentstudies inpatients, who are hospitalized in Intensive Care Unit (ICU), show
that 51% of them have infections, and 71% are given treatment. Bacterial and
some fungal infections, as opportunistic microorganism are the primary concern.
Hospitalizing in ICU is associated with increasing in mortality rate and excess
expenses. Pharmacokinetics, absorption, distribution, metabolism, and excretion
of drugs experience many changes in critical illness.
NTM, are a group of mycobacteria which
is not a causative organism of tuberculosis or leprosy, so they called as
Mycobacteria Other Than Tuberculosis (MOTT). NTM bacteria are a family of
small, rod-shaped bacilli which have more than 150 species. Atypical
mycobacteria have different favor in choosing their environment and are
identified as environmental mycobacteria. NTM are the causative organisms in
pulmonary diseases like tuberculosis, lymphadenitis, skin disease, or
disseminated disease. Major clinical manifestations of NTM Infections are
presented in Table 1. In 1950s, they were accepted as human pathogens. Unlike
tuberculosis and leprosy, spreading NTM infections from one person to another
person is rare. Environmental exposure is the major way of contagion. The risk
of getting infected by a particular species of NTM is dependent on
pathogenicity of microorganism, the method of exposure and frequency of exposure.
In the last decade, (NTM) infections have worldwide increasing in incidence and
mortality. The reasons for this increase are not obvious. But increasing
incidence of acquired immune compromised syndrome, cancer, diabetes mellitus,
chronic lung injuries, and continues supportive ventilation could be causative.
A retrospective study in medical center
of Taiwan from January 1999 to June 2007 was planned to evaluate medical ICU
patients whose respiratory specimens were positive for NTM. They defined tree
group of patients, one group with NTM pulmonary infection, the other with NTM
colonization and a control group who have culture negative samples for
mycobacteria. Clinical sign, symptoms and outcomes were compared. Their finally
result was that, increment in mortality rate in patients who have NTM
pulmonary. Suitable treatment against NTM would followed by better result.
