Conservative treatment of prosthetic valve endocarditis due to Mycobacterium fortuitum.

Described here is the case of a patient with infective endocarditis in a prosthetic valve due to a Mycobacterium fortuitum-group organism. The patient was treated medically and had a favorable clinical response. This is only the second report of survival after Mycobacterium fortuitum-group endocarditis, and the first of survival without surgical intervention. The duration of treatment is not well defined for this patient, but life-long suppressive therapy will likely be required.

Expansion of large granular lymphocytes following Pseudomonas infection in a patient with adult-onset Still's disease.

We report a patient who had a 4-year history of adult-onset Still's disease (AOSD) and showed a prominent increase in large granular lymphocytes (LGL) when she developed severe Pseudomonas conjunctivitis due to Pseudomonas aeruginosa, skin eruptions, liver damage, and abnormal findings in coagulation studies, without any evidence of active viral activation, hemophagocytosis, or malignancies. The increased LGL cells were CD3(+)CD8(+), and disappeared promptly after the administration of antibiotics combined with prednisolone, with subsequent stabilization of her general condition.

Stability of SM-7338, a new carbapenem in mediums recommended for the susceptibility testing of anaerobic bacteria and gonococci.

The stability of SM-7338 was compared to that of imipenem in media used for susceptibility testing anaerobic bacteria and Neisseria gonorrhoeae. SM-7338 was more stable in all media than imipenem. For tests with anaerobic bacteria, the broth-disk elution (in thioglycolate) and other methods recommended by the National Committee for Clinical Laboratory Standards can be accurately used for SM-7338. However, the cysteine content of IsoVitaleX (25.9 g/L) supplement inactivates SM-7338 (20-fold reduction) in gonococcal susceptibility test systems with GC agar base. A cysteine-free supplement would be advised for tests with the carbapenems and clavulanic acid. The SM-7338 disk diffusion test (10 micrograms) results were not significantly influenced by the inactivating substances in the media.

Making the most of surveillance studies: summary of the OPTAMA Program.

Antibiotic surveillance studies lack consideration of pharmacodynamics and provide little information about optimal dosing. By using minimum inhibitory concentration (MIC) data derived from a global surveillance study and Monte Carlo simulation, the Optimizing Pharmacodynamic Target Attainment using the MYSTIC Antibiogram (OPTAMA) Program was established to impart greater understanding of the ability to attain pharmacodynamic exposure for specific dosing regimens and their relationship with percent susceptibility. Early OPTAMA studies focused on determining the cumulative fraction of response (CFR) for various antibiotics against Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa regionally in Europe and the Americas. Later reports considered the prevalence of specific bacteria causing infections to estimate the CFR for empiric therapy of pneumonia, bloodstream, complicated skin/skin structure, and intra-abdominal infections. Collectively, the approach of the OPTAMA Program provides a novel tool that complements susceptibility data to help in the selection of appropriate empirical antibiotic therapy at the national, regional, and institutional level.

Risk factors and clinical outcomes of nosocomial multi-drug resistant Pseudomonas aeruginosa infections.

Risk factors for multi-drug resistant Pseudomonas aeruginosa (MDRP) infections were investigated using a case-control study design involving MDRP patients (N = 44) and controls (N = 68). A retrospective cohort study was performed to study the predictive factors of clinical outcome in MDRP patients. Multivariate analysis demonstrated that previous exposure to imipenem/meropenem [odds ratio (OR), 44.8] and mechanical ventilation (OR 8.2) were risk factors for nosocomial infections of MDRP. Of 44 cases of MDRP infections, 20 patients died directly from P. aeruginosa infections. Pulsed-field gel electrophoresis (PFGE) analysis on serial isolates from three patients showed that profiles of isolates from the same patient were closely related or indistinguishable. Multivariate analysis demonstrated that patients with adverse clinical outcomes were more likely to have been treated with mechanical ventilation (OR 12.8), and more likely to have MDRP resistance patterns that did not change during treatments (OR 26.5). We concluded that mechanical ventilation and previous exposure to imipenem/meropenem were independent risk factors for MDRP infections, while mechanical ventilation and antibiotic resistance switch were predictive factors of outcomes of MDRP infections.

Trimethoprim-sulfamethoxazole induced rash and fatal hematologic disorders.

Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination chemotherapeutic agent, a commonly used antibiotic. Adverse drug reactions occur in 6-8% of patients. Although, the most common adverse reactions include mild gastrointestinal distress and cutaneous events, also a wide range of hematological abnormalities have been ascribed to TMP-SMX. We report a 40-year-old male patient who developed an early onset neutropenia, thrombocytopenia, generalised rash and oral candidiasis after 5 days long TMP-SMX therapy. Although generalised rash may seen more and improves with discontinuation of the therapy; severe neutropenia, thrombocytopenia and oral candidiasis are seen very rare and rarely leads to fatality as it was in our case. Despite thrombocyte transfusions, whole blood transfusions, red cell concentrates and filgrastim therapy we lost our patient. We want to underline that although the TMP-SMX combination is usually well tolerated it can also lead to fatal complications.

Antibiotic susceptibility of Burkholderia pseudomallei from tropical northern Australia and implications for therapy of melioidosis.

From a prospective melioidosis study commencing in 1989 at Royal Darwin Hospital, 170 initial isolates of Burkholderia pseudomallei were available for susceptibility testing. Of these 163 (96%) were susceptible to meropenem/imipenem, ceftazidime, trimethoprim-sulphamethoxazole (SMX/TMP) and doxycycline. Seven (4%) showed primary resistance; three had low-level resistance to SMX/TMP, one to ceftriaxone and amoxycillin/clavulanate (AMOX/CA) and three to doxycycline. Of 167 patients who survived their initial presentation, seven (4%) had culture positive infections which persisted for greater than 3 months after start of therapy. All ultimately cleared carriage of B. pseudomallei though three required changing to SMX/TMP after development of doxycycline resistance. Nineteen (11%) of the initial survivors clinically relapsed and 17 of these had repeat isolates available for testing. Four of these had acquired resistance: one to doxycycline, one to AMOX/CA and ceftazidime, one to SMX/TMP and one to both SMX/TMP and doxycycline. Molecular typing using randomly amplified polymorphic DNA and pulsed-field gel electrophoresis showed all but one relapse isolate to be the same as the original strain. These data are similar to published data from Thailand. As melioidosis has a high mortality (21% in this series) these results emphasize the need for prolonged eradication therapy and regular clinical and microbiological monitoring so that the emergence of resistance can be detected early and appropriate treatment modifications made.

Emphysematous gastritis and severe aplastic anemia.

Emphysematous gastritis is a life-threatening disease. It is characterized by the presence of gas within the wall of the stomach. The etiology includes firstly infections with gas-forming organisms; other predisposing causes are the ingestion of corrosive substances and alcohol abuse. Diagnosis is based on radiological techniques, mainly computed tomographic scan (CT). The election treatment is antibiotics and surgery. The evolution is generally fatal. We present the first known case reported, which is associated with aplastic anemia with immunosuppressive therapy, its evolution with medical treatment and a literature review.
