Abstract
BACKGROUND Antiretroviral regimens containing a second-generation integrase strand-transfer inhibitor (INSTI) plus 2 nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) are the recommended therapy for people with HIV (PWH) who are antiretroviral-naïve or on stable antiretroviral therapy (ART) with viral suppression. Real-world data on the virologic effectiveness of co-formulated bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) among PWH with virologic failure while receiving other ART remain sparse. METHODS We retrospectively reviewed the medical records of PWH who had viral rebound with plasma HIV RNA >1000 copies/mL and were switched to either dolutegravir combined with 2 NRTIs or BIC/FTC/TAF. The primary end point was re-achieving viral suppression within the first 48 weeks of switch. The association between NRTI-related resistance-associated mutations (RAMs) and virologic effectiveness was examined. RESULTS Seventy-nine PWH with viral rebound while receiving other antiretroviral regimens were included. Within the first 48 weeks of switch, the overall probability of re-achieving viral suppression was 79.7% (82.5% [33/40] and 76.9% [30/39] for BIC/FTC/TAF and dolutegravir-based regimens, respectively, p = 0.78). PWH with a higher CD4 lymphocyte count (adjusted odds ratio, per 100-cell/mm3 increase, 1.41; 95% confidence interval, 1.02-1.95) were more likely to re-achieve viral suppression. Among PWH switching to BIC/FTC/TAF who had pre-existing RAMs to NRTIs before switch, 14 of 15 (93.3%) successfully achieved viral suppression. CONCLUSIONS Switching to BIC/FTC/TAF and dolutegravir-based regimens could re-achieve viral suppression in four-fifth of the PWH who experienced viral rebound during treatment with other antiretroviral regimens. Pre-existing NRTI-related RAMs did not have adverse impact on the effectiveness of dolutegravir combined with 2 NRTIs or BIC/FTC/TAF.

Abstract
BACKGROUND Real-world experience with low-level viremia (LLV) and its impact remain less reported among people living with HIV (PLWH) who receive antiretroviral therapy (ART) containing second-generation integrase strand transferase inhibitors (INSTIs), including dolutegravir and bictegravir. METHODS Virally suppressed PLWH who had achieved plasma HIV RNA load (PVL) <50 copies/mL for ≥6 months and were switched to either dolutegravir- or bictegravir-based ART were included in this retrospective cohort study. The incidence rates of developing LLV events (PVL, 50-199 copies/mL) and virologic failure (VF) (PVL ≥1000 copies/mL) were compared between the dolutegravir and bictegravir cohorts. RESULTS A total of 623 and 862 PLWH switched to dolutegravir-based and bictegravir-based ART, respectively, were included. The incidence rates of developing LLV were 6.2 per 100 person-years of follow-up (PYFU) in the bictegravir cohort and 3.8 per 100 PYFU in the dolutegravir cohort (incidence rate ratio [IRR], 1.63; 95% confidence interval [CI], 0.90-2.95, p=0.08), while the rates of VF were 0.69 per 100 PYFU and 0.95 per 100 PYFU, respectively, in the bictegravir and dolutegravir cohort (IRR, 0.72; 95% CI, 0.12-3.39, p=0.34). Presence of LLV events was not associated with subsequent VF in multivariate analysis. Secondary analysis also demonstrated that resistance-associated mutations (RAMs) to nucleoside reverse-transcriptase inhibitors before switch were not associated with adverse virologic outcomes in either cohort. CONCLUSIONS Among virally suppressed PLWH, the incidences of developing LLV or VF were similar after switch to dolutegravir- or bictegravir-based ART. Preexisting RAMs to nucleoside reverse-transcriptase inhibitors or the LLV events were not associated with subsequent VF.

Abstract
The nephrotoxicity of sofosbuvir (SOF) on human immunodeficiency virus and hepatitis C virus (HIV/HCV)-coinfected patients receiving antiretroviral therapy (ART) remains controversial. We prospectively compared the estimated glomerular filtration rate (eGFR) changes in 167 patients receiving SOF-based direct-acting antivirals (DAAs) who also received tenofovir disoproxil fumarate (TFV)-based (n = 116) and TFV-free ART (n = 51). The eGFR was assessed by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation, and the eGFR changes between ART regimens were compared by the generalized estimated equation. During DAA treatment, participants on TFV-based ART had a higher eGFR decline than those on TFV-free ART (slope coefficient difference: -0.82 ml/min/1.73 m2 /month [95% CI: -1.21 to -0.43]; p < 0.001), whereas the eGFR changes did not differ between groups (slope coefficient difference: 0.13 ml/min/1.73 m2 /month [95% CI: -0.32 to 0.58]; p = 0.42) after discontinuing DAAs. Participants on TFV TDF-based ART had a higher eGFR decline than those on TFV alafenamide fumarate (TAF)-based ART (slope coefficient difference: -0.31 ml/min/1.73 m2 /month [95% CI: -0.50 to -0.12]; p = 0.01). After discontinuing DAAs, the eGFR changes did not differ between groups (slope coefficient difference: 0.06 ml/min/1.73 m2 /month [95% CI: -0.98 to 1.10]; p = 0.91). In conclusion, HIV/HCV-coinfected patients on TFV-based ART had a slight eGFR decline compared to those on TFV-free ART during SOF-based DAA therapy. A similar trend between TDF-based and TAF-based ART was also observed. Because the differences of eGFR changes are limited, the physicians should not discourage the use of SOF-based DAAs in HIV-positive patients on TFV-based ART.

Abstract
We used an in-house saponin-based extraction method to evaluate the performance of the Bruker Biotyper matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) system for the identification of bacteria and fungi in 405 positively flagged blood culture bottles. Results obtained from MALDI-TOF/MS were compared with those obtained using conventional phenotypic identification methods. Of the 405 positively flagged blood culture bottles, 365 showed monomicrobal growth and were correctly identified to the species (72.1%) or genus (89.6%) level using the Bruker Biotyper system. The remaining 40 positively flagged blood culture bottles showed polymicrobial growth. Of them, 82.5% (n = 33) of the isolates were correctly identified to the species level and 92.5% (n = 37) to the genus level using the Bruker Biotyper system. The overall accuracy of identification to the genus level in flagged blood cultures was 89.5% for Gram-positive organisms, 93.5% for Gram-negative pathogens and 71.9% for fungi. Confidence scores were ≥1.500 for 307 (75.8%) bottles, ≥1.700 for 249 (61.5%) bottles and ≥2.000 for 142 (35.1%) bottles. None of the yeast cultures yielded scores ≥1.700. Using an identification-score cutoff of ≥1.500, the MALDI Biotyper correctly identified 99.2% of Gram-positive bacteria, 97.6% of Gram-negative bacteria and 100% of yeast isolates to the genus level and 77.6% of Gram-positive bacteria, 87.1% of Gram-negative bacteria and 100.0% of yeast isolates to the species level. The overall rate of identification using our protocol was 89.9% (364/405) for genus level identification and 73.1% (296/405) for species level identification. Yeast isolates yielded the lowest confidence scores, which compromised the accuracy of identification. Further optimization of the protein extraction procedure in positive blood cultures is needed to improve the rate of identification.

Abstract
Lactic acidosis (LA), a rare but life-threatening adverse effect associated with antiretroviral therapy, has been reported with an increasing frequency since the mid1990s. From June 1994 to June 2002, a total of six patients, four males and two females with a median age of 43 years (range, 30 to 74 years), had been diagnosed with LA. The estimated incidence of LA was 5.1 per 1000 patient-years (PYs) on highly active antiretroviral therapy (HAART) (95% confidence interval [95% CI], 4.5-5.5 per 1000 PYs) and 4.4 per 1000 PY on nucleoside analogues (NAs) (95% CI, 3.9-4.7 per 1000 PYs). Their median body mass index at diagnosis of LA was 17.6 kg/m2 (range 16.3 to 22.6 kg/m2). The median CD4+ lymphocyte count at the initial diagnosis of HIV infection and at the onset of LA was 38 cells/µL (range, 4 to 103 cells/µL) and 108 cells/µL (range, 79 to 224 cells/µL), respectively. The most common symptoms were nausea, vomiting, and dyspnoea. All of the patients had findings suggestive of NA-related mitochondrial toxicity, such as myositis, pancreatitis, fatty hepatitis, peripheral neuropathy or lipodystrophy. The prescribed NA related to LA were stavudine in six patients, lamivudine, five, and didanosine, one. Despite treatment, all patients died of persistent circulatory collapse following LA. The median duration from diagnosis to death was eight days (range, 4-17 days). Our report highlights that clinicians caring for patients with AIDS should be alerted to the potentially fatal LA associated with antiretroviral therapy when patients present with low body mass index, lipodystrophy, unexplained abdominal symptoms, dyspnoea, or elevated aminotransferases.

Abstract
We assessed the seroprevalence of Toxoplasma gondii infection and incidence of toxoplasma encephalitis (TE) in 844 non-haemophiliac HIV-infected patients in Taiwan between June 1994 and April 2003. Approximately 70% (69.3%) of them had a baseline CD4+ lymphocyte count of 200 × 106/L or less, and more than 70% (73.9%) having initiated highly active antiretroviral therapy. The seroprevalence of T. gondii infection was 10.2%, which did not differ with sex, age, route of transmission, birth inside or outside of Taiwan, or CD4+ lymphocyte stratifications. After a median observation duration of 603 days (range, 1–3264 days), 10 (1.2%) patients developed 11 episodes of TE after a median interval of 30 days (range, 1–941 days) between enrolment and diagnosis of TE, with an incidence of 0.59 per 100 person-years (PY) (95% confidence interval, 0.56–0.63 per 100 PY). We concluded that the incidence of TE of HIV-infected patients in Taiwan was lower than that reported in western countries because of a lower seroprevalence of T. gondii infection and use of antimicrobial prophylaxis and antiretroviral therapy, although most of the patients were at the late stage of HIV infection.

Abstract
Data are limited on the effectiveness and safety of peginterferon plus ribavirin in HIV-infected Asian patients with acute or chronic HCV infection. HIV-infected Taiwanese patients with acute HCV infection received peginterferon plus weight-based ribavirin for 24 weeks (n = 24), and those with chronic HCV genotype 1 or 6 (HCV-1/6) and HCV genotype 2 or 3 (HCV-2/3) infection received response-guided therapy for 12-72 and 24-48 weeks, respectively (n = 92). The primary endpoint was sustained virologic response (SVR), defined as undetectable HCV RNA 24 weeks off-therapy. The SVR rates were 83% and 72% in patients with acute and chronic HCV infection (p = 0.30), and 68% and 72% in patients with chronic HCV-1/6 and HCV-2/3 infection (p = 0.48), respectively. While no factors predicted SVR in acute HCV and chronic HCV-2/3 infection, age (odds ratio [OR] per 1-year increase: 0.88, 95% confidence interval [CI]: 0.78-0.99, p = 0.04), HCV RNA (OR per 1-log10 increase: 0.18, 95% CI: 0.03-0.98, p = 0.03), IL28B genotype (OR: 5.52, 95% CI: 1.55-12.2, p = 0.02), and RVR (OR: 9.62, 95% CI: 3.89-15.3, p = 0.007) predicted SVR in chronic HCV-1/6 infection. In conclusion, the SVR rates of peginterferon plus ribavirin for 24 weeks and for response-guided 12-72 weeks are satisfactory in HIV-infected Taiwanese patients with acute and chronic HCV infection.

Abstract
To ascertain whether hepatitis C (HCV) co-infection affects the progression of HIV infection, we initiated an eight-year prospective observational study at a university hospital in Taiwan where seroprevalences of HCV antibody and HIV antibody were low. Fifty-three (12.0%) consecutive non-haemophiliac HIV1-infected patients with HCV co-infection and 387 (88.0%) patients without HCV and hepatitis B co-infection were enrolled between June 1994 and June 2002 and observed until December 2002. Outcomes evaluated included the risk for acute hepatitis, hepatic decompensation, HIV disease progression and mortality, and changes of CD4+ count and plasma viral load (PVL) after initiation of highly active antiretroviral therapy (HAART) at the end of the study. The baseline CD4+ count, PVL and proportion of patients with AIDS-defining opportunistic illnesses (OI) at study entry were similar between patients with HCV co-infection and those without co-infection, but HCV-co-infected patients were older (39 versus 35 years, P = 0.01) and had a higher proportion of intravenous drug use (17.0% versus 0.8%, P < 0.001). After a total observation duration of 1137 patient-years (PY) (median, 791 days; range, 3-3053 days), the incidence of acute hepatitis in HCV-co-infected patients was 13.89 per 100 PY (95% confidence interval [CI], 13.31-14.49) and that in patients without co-infection was 6.39 per 100 PY (95% CI, 6.24-6.55 per 100 PY), with an adjusted odds ratio (OR) of 2.769 (95% CI, 1.652-4.640). At the end of the study, CD4+ count increased by 137 x 10(6) and 157 x 10(6)/L in patients with and without HCV co-infection, respectively, (P = 0.47). The proportions of achieving undetectable PVL (<400 copies/mL) after HAART was similar (76.7% versus 74.9%, P = 0.79). The adjusted OR for development of new AIDS-defining OI was 1.826 (95% CI, 0.738-4.522) in HCV-co-infected patients as compared with HCV- uninfected patients. The adjusted hazards ratio for death of HCV-co-infected patients when compared with those without co-infection was 0.781 (95% CI, 0.426-1.432). Our findings suggested that HCV co-infection was associated with a significantly higher risk for acute hepatitis in HIV-infected patients receiving antiretroviral therapy, but it had no adverse impact on virological, immunological and clinical responses to HAART and survival when compared with patients without HCV and HBV co-infection.

Abstract
To understand the impact of hospital-acquired infections on mortality and medical costs in modern medical care systems in different healthcare settings, we performed a case-control study at a medical centre and two community hospitals. A total of 144 and 129 adult case-control pairs who received care in a 2000-bed tertiary referral medical centre and two 800-bed community hospitals, respectively, between October 2002 and December 2002 were enrolled. Prolongation of hospital stay, extra costs and complications associated with hospital-acquired infections were analysed. Patients in the medical centre had more severe underlying disease status (P < 0.001), more malignancies (P < 0.001), more multiple episodes of hospital-acquired infection (p = 0.03), and more infections with multidrug-resistant bacteria (P < 0.001) than patients in community hospitals. The additional length of hospital stay and extra costs were similar for patients with hospital-acquired infections in the community hospitals and the medical centre (mean 19.2 days vs. 20.1 days, P = 0.79; mean 5335 US dollars vs. 5058 US dollars, P = 0.83; respectively). The additional length of hospital stay and extra costs in both the medical centre and the community hospitals were not related to the sites of infection or the bacterial pathogens causing hospital-acquired infections, although medical costs attributable to hospital-acquired fungal infections due to Candida spp. were much higher for patients in the medical centre. Prevalence of hospital-acquired-infection-related complications, such as adult respiratory distress syndrome, disseminated intravascular coagulation, organ failure or shock, was similar between the two groups, but patients in the medical centre had a higher mortality rate because of their underlying co-morbidities.

Abstract
Acinetobacter baumannii is ubiquitous and has recently become one of the most important healthcare-associated (HA) pathogens in hospitals. Infection caused by this organism often leads to significant morbidity and mortality. Outbreaks of pan-drug resistant Acinetobacter baumannii (PDRAB) have rarely been reported. During a two-month period, an outbreak of PDRAB colonization and infection affecting 7 patients occurred in our surgical intensive care unit (SICU). The colonized sites were respiratory tract (N = 7) and central venous catheter (N = 2). One of the patients had a surgical wound infection. Extensive environmental contamination was identified, including sites such as bed rails, bedside tables, surface of ventilators and infusion pump, water for nasogastric feeding and ventilator rinsing and sinks. All of the isolates were analysed by pulsed-field gel electrophoresis (PFGE) and showed an identical pattern. After use of strict cohort nursing, hand hygiene environmental cleaning, and replacement of a dysfunctional high-efficiency particulate air filter (HEPA), the outbreak was controlled.

Abstract
Seven AIDS patients with disseminated cryptococcosis who had had immune reconstitution following highly active antiretroviral therapy (HAART) had discontinued their secondary antifungal prophylaxis to prevent relapse of Cryptococcus neoformans infection. The median CD4+ count was 236 cells/ micro L (range, 117-404 cells/ micro L; mean, 247 cells/ micro L) and the plasma viral loads were undetectable in five patients at discontinuation of antifungal prophylaxis. No relapse of cryptococcosis was detected in these patients after a median observation duration of nine months (range, 5.5-4.1 months, mean, 14.6 months) following discontinuation. Our data and review of the literature suggest that discontinuation of fluconazole prophylaxis is safe in patients with reconstitution of immunity following#10; initiation of HAART.

Abstract
The in vitro antimicrobial activities of moxifloxacin were compared with 7 other antimicrobial agents. A total of 707 isolates of 11 common pathogenic bacteria were collected from the National Taiwan University Hospital; antimicrobial activities against these isolates were evaluated by minimum inhibitory concentration using an agar-dilution method. Most common pathogenic bacteria were susceptible to moxifloxacin, including methicillin-susceptible and -resistant Staphylococcus aureus, methicillin-susceptible and -resistant Staphylococcus epidermidis, Streptococcus pneumoniae, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Pseudomonas aeruginosa, Burkholderia cepacia, Acinetobacter baumannii, and Stenotrophomonas maltophilia. For many of these bacterial species, moxifloxacin was the most active antimicrobial agent compared with the third- and fourth- generation cephalosporins, carbapenems, monobactam, and other quinolones. Some strains of methicillin-resistant S. aureus and methicillin-resistant S. epidermidis demonstrated very low levels of minimum inhibitory concentration for moxifloxacin, suggesting the potential application of the drug to treat some drug-resistant gram-positive bacterial infections. Moxifloxacin was less active against P. aeruginosa, but was more active against S. maltophilia when compared with other fluoroquinolones. In conclusion, moxifloxacin exhibits an increased potency against gram-positive bacteria as compared with other tested antimicrobial agents, while preserving excellent activity against gram-negative bacteria. The drug appears to be a promising agent expressing activity against a wide variety of bacteria in Taiwan.

Abstract
OBJECTIVE To investigate the effect of combined treatment of Shanghanglian (SHHL) and recombinant interferon alpha 2a on Coxsackie virus B3 replication. METHODS Microdose cytopathogenic inhibition effect assay was used in Wish and Vero cultured cells. rIFN-alpha 2a was applied 12 hours before Coxsackievirus B3 inoculation and SHHL was applied 1 hour after Coxsackievirus B3 inoculation. RESULTS 0.125 mg.ml-1 SHHL has a synergism with rIFN-alpha 2a to inhibit CPE caused by Coxsackievirus B3 on the Wish and Vero cells. The anti-cox-sackievirus activity of combined treatment was 2.58 times higher than that of rIFN-alpha 2a treatment. CONCLUSION This combined treatment of drugs may be useful in preventing and treating Coxsackie B3 Virus infection.

Abstract
Chylothorax is bacteriostatic in nature. Bacterial infection rarely develops in chylothorax and has never been reported in a non-immunocompromised host. A 33-year-old woman was admitted to National Taiwan University Hospital because of fever and right pleuritic pain. Chest roentgenography and computed tomography revealed right pleural effusion. Examination of the pleural effusion revealed a profile compatible with empyema and chylothorax. Culture of the pleural effusion yielded Streptococcus agalactiae. The woman was not immunocompromised. This is the first report of infected chylothorax caused by Streptococcus agalactiae in a non-immunocompromised host.

Abstract
BACKGROUND The safety and efficacy of cefpirome (CPM), a fourth-generation cephalosporin, has not yet been studied in an Asian population. METHODS Sixty-nine adult Chinese patients with sepsis due to bacterial infections were enrolled in the study and randomly assigned to receive CPM (2 g i.v. every 12 h) or ceftazidime (2 g i.v. every 8 h). RESULTS Both groups were comparable in terms of demographic, clinical and microbiological features. The causative pathogen was Escherichia coli or Klebsiella pneumoniae in the majority of microbiologically documented cases. The rates of clinical response (94 vs. 94%) and bacteriological response (65 vs. 68%) were similar in both groups. Similar adverse events, including rashes, gastrointestinal upset and asymptomatic elevation of hepatic enzymes, occurred in a minority of patients in both groups. All events were self-limited after discontinuation of the drugs. CONCLUSION CPM is as safe and effective as ceftazidime in the treatment of sepsis due to bacterial infections in Chinese patients.

Abstract
Central venous catheterization represents a significant medical advancement, particularly in the treatment of critical ill. However, there is a high risk of central venous catheters-related infection. A novel antiseptic central venous catheter, made of polyurethane and impregnated with chlorhexidine and silver sulfadiazine, was developed to reduce the risk of catheters-related infection. In this study, we did a randomized clinical study to determine the efficacy by using antiseptic catheters for the prevention of central venous catheters-related infection in the intensive care units. A total of 204 patients with 235 central venous catheters were studied at the surgical intensive care units at National Taiwan University Hospital between November 1998 and June 1999. Participants received either a standard triple-lumen polyurethane catheter or an antiseptic catheter (Arrow International, Reading, Pennsylvania, USA). Both were indistinguishable from each other. Compared to standard polyurethane catheters, antiseptic catheters were less likely to be colonized by microorganisms when they were cultured at the removal (8.0 versus 20.0 colonized catheters per 100 catheters; relative risk 0.34 [95% CI, 0.15 to 0.74]; p<0.01). There was no significant differences between both groups in catheter-related infections (0.9 versus 4.9 infections per 100 catheters; relative risk 0.17 [95% CI, 0.03 to 1.15]; p = 0.07). Gram-positive cocci and fungi were more likely to colonize in the standard polyurethane catheters (p = 0.06 and 0.04, compared to antiseptic catheters respectively). Two of our cases in the control group died directly due to catheter-related candidemia. No adverse reactions such as hypersensitivity or leukopenia were found in the antiseptic catheter group. Our study showed that central venous catheters with antiseptic coating were safe and had less risk of colonization of bacteria and fungi than standard catheters in the critically ill patients.

Abstract
The clinical spectrum of AIDS and changes of morbidity and mortality associated with HIV infection following initiation of highly active antiretroviral therapy (HAART) are rarely described in the less developed countries in the Asia-Pacific region. We prospectively observed on a follow-up basis 309 HIV-infected patients (82.8% with AIDS) at National Taiwan University Hospital in Taiwan, where highly active antiretroviral therapy (HAART) has been provided to all patients at no charge at any stage of HIV infection since April 1, 1997, to describe the spectrum of HIV-associated opportunistic diseases and evaluate changes of morbidity and mortality from June 24, 1994 through June 23, 1999. Of the patients, 59.3% at study entry had a CD4+ lymphocyte count of <50 cells/microliter. The five leading HIV-associated opportunistic infections included oroesophageal candidiasis (195 patients), Pneumocystis carinii pneumonia (93), tuberculosis (77), mucocutaneous herpes simplex infection (74), and cytomegalovirus diseases (73). The incidence rates of seven major AIDS-defining opportunistic diseases were declining though the changes of the relative proportions varied. The median duration of hospitalization decreased from 36 days in 1995 to 12 days in 1999 (p =.0001). Overestimated mortality rate declined from 148.4 per 100 patient-years in 1995 to 7.4 per 100 patient-years in 1999 (p =.0001) whereas the underestimated mortality rate declined from 110.5 to 5.39 per 100 patient-years (p =.0001). Risk ratio (RR) for mortality in patients who received HAART compared with those who did not was 0.410 (95% confidence interval [CI], 0.249-0.674; p =.0004) and the RR was 0.250 (95% CI, 0.127-0.492; p =.0001) when the analysis was limited to patients with an initial CD4+ lymphocyte count <100 cells/microliter and follow-up duration >30 days after adjusting for their age, gender, type of risk behavior, and CD4+ lymphocyte count. Morbidity and mortality were declining with each study year even in a population consisting mainly of patients at the advanced stage of HIV infection in Taiwan. Earlier diagnosis, accumulation of clinical experience, and use of HAART were associated with lower mortality rates.

Abstract
Proper and timely choice of the antibiotic therapy for the management of infection in hospitalized patients is an immense challenge to the clinician. A newly developed extended-spectrum fourth-generation cephalosporin cefepime, has been shown to have good activity against both gram-positive and gram-negative organisms. In order to further establish the efficacy and safety of cefepime in the treatment of adult hospitalized patients in Taiwan, we reviewed the medical records of all patients who received cefepime therapy for more than 72 h at the National Taiwan University Hospital during the period from January 1999 to April 1999. A total of 55 patients were treated with cefepime during this period. Thirty-two of them were males and 23 were females. Their ages ranged from 16 to 94 years old (average, 67). All had severe infections with a mean Acute Physiology and Chronic Health Evaluation II (APACHE II) score of 18. More than half (56%) of the infections were nosocomial. The most common infections included pulmonary infection (49%), intra-abdominal infection (27%), skin and soft tissue infection (15%), febrile neutropenia (7%), and intravascular device infection (5%). All but one of the patients (98%) had pre-existing medical disease. Malignancy (49%) was the most common underlying illness. Pseudomonas aeruginosa (23 isolates) and Enterobacter cloacae (21) were the most common pathogens causing infections. Thirty-one (58%) of the patients were effectively treated with cefepime. Twenty of the patients died during the study period with most deaths attributable to persistent microbial infection and superinfection, especially Acinetobacter baumannii and fungal infection. Adverse effects developed in six patients, including eosinophilia (3 patients), leukopenia (2), skin rash (1), and drug related fever (1), but all were mild and transient. The results of this study show that cefepime is a safe and effective agent in the treatment of adult patients with severe infection in Taiwan.

Abstract
Bacteremia due to Erysipelothrix rhusiopathiae is rare; the most common presentation reported in the literature is endocarditis. We report a 32-year-old man with oropharyngeal cancer who developed aspiration pneumonia and E. rhusiopathiae bacteremia, and presented with fever, chills, dyspnea, and productive cough with purulent sputum. Despite treatment with amoxicillin/clavulanate and nutritional support for 9 days, he died of respiratory failure. He had no clinical evidence of endocarditis. He had no history of animal or occupational exposure, and might have been colonized with E. rhusiopathiae in the oral cavity, followed by aspiration pneumonia and bacteremia. A fatal outcome in a patient with bacteremia due to E. rhusiopathiae without endocarditis is rare.

Abstract
Carriers of methicillin-resistant Staphylococcus aureus (MRSA) in hospital constitute a reservoir of infections and increase the risk of bacteremia and wound infection. In this prospective randomized trial, we tested the effectiveness of oral fusidic acid for eradication of MRSA colonization. From March 1997 through February 1998, patients with MRSA colonization in medical intensive care units in a large urban teaching hospital were randomly assigned to receive fusidic acid 500 mg q8h orally for 7 days or no anti-staphylococcal treatment. Twenty-three MRSA carriers were found during the study period and 16 were eligible for evaluation; six of them received fusidic acid. MRSA colonization was cleared in only two of the six patients with fusidic acid treatment, and later recurred in one of them. MRSA disappeared for 1, 2, 7, 7, and 8 weeks, respectively, in five of the 10 patients without treatment. MRSA persisted in the other five cases. Although all MRSA isolates found in the initial surveillance culture were susceptible to fusidic acid (MIC </= 2 microg/mL), seven isolates from two patients after fusidic acid treatment demonstrated high fusidic acid resistance (MIC 64 to >/= 256 microg/mL). Pulsed-field gel electrophoresis pattern analysis showed that the resistant strains were genetically identical to the susceptible strains isolated from the same patient before fusidic acid treatment, in both cases. However, genetically distinct strains colonized in the same individual during follow-up were found in four out of 16 cases. We conclude that oral fusidic acid alone is not suitable for eradication of MRSA colonization, and may lead to the emergence of resistant strains.

Abstract
The pattern of fever response to empiric anti-tuberculosis therapy in patients with tuberculosis (TB) and human immunodeficiency virus (HIV) infection, and the relationship between fever response patterns and anti-TB drug susceptibility profiles of Mycobacterium tuberculosis isolates are rarely described. In this study, we evaluated the fever responses to a four-drug anti-TB regimen in 26 HIV-infected patients with culture-proven extrapulmonary TB, and compared the results with those in 12 patients with disseminated Mycobacterium avium complex (DMAC) infection treated with a clarithromycin-containing regimen. The CD4 lymphocyte counts did not differ significantly between TB and DMAC patients (26 x 10(6)/L in TB patients vs 5 x 10(6)/L in DMAC patients). Drug susceptibility data were available for 22 patients with TB. Most TB patients had rapid defervescence after initiation of anti-TB therapy. Fever resolved within 1 week in 85% (22/26) of patients, including three of six (50%) with multidrug-resistant (MDR) TB. The median duration of fever in patients with drug-susceptible TB was similar to that in patients with drug-resistant TB (3 vs 4 days, p = 0.33). However, patients with MDR-TB were more likely than those with non-MDR TB to have fevers lasting longer than 1 week after initiating anti-TB therapy (3/6 vs 1/16, p = 0.046). Only 17% (2/12) of the patients with DMAC infection became afebrile within 1 week of beginning anti-MAC therapy (p < 0.001 vs those with TB). Our observations suggest that in HIV-infected patients with advanced immunosuppression, anti-TB regimens achieve significantly faster defervescence in TB patients than do anti-MAC regimens in DMAC patients. Rapid defervescence in patients with TB does not necessarily indicate that TB isolates are not MDR strains.

Abstract
Agranulocytosis is a rare complication of antithyroid drugs, and the aetiologies of community-acquired, life-threatening infections in patients taking these drugs have not previously been systematically described. Of 5653 hyperthyroid patients treated with antithyroid drugs at National Taiwan University Hospital between January 1987 and December 1997, 13 (0.23%) developed agranulocytosis with life-threatening infections. The most common presentations were fever (92%) and sore throat (85%). Initial clinical diagnoses were acute pharyngitis (46%), acute tonsillitis (38%), pneumonia (15%) and urinary tract infection (8%). Positive blood cultures from six patients yielded Pseudomonas aeruginosa (3), Escherichia coli (1), Staphylococcus aureus (1), Capnocytophaga species (1). Two patients died of uncontrolled infection, thyroid storm and multiple organ failure. Cases of antithyroid-drug-induced agranulocytosis in the English language literature are reviewed; Gram-negative bacilli, including Klebsiella pneumoniae (4 patients) and P. aeruginosa (3), were the most common pathogens in clinical isolates. Our observation and review suggest that broad-spectrum antibiotics with anti-pseudomonal activity should be given to patients with antithyroid drug-induced agranulocytosis who present with severe infection.

Abstract
OBJECTIVE To examine whether the serial measurement of plasma cytokine levels can assist in the early recognition of AIDS/tuberculosis patients with poor response to anti-tuberculosis treatment. DESIGN Longitudinal, prospective cohort study. SETTING A university hospital, the largest centre for HIV/AIDS patients in Taiwan. METHODS Between January 1997 and September 1998, 25 consecutive patients with advanced HIV infection and suspected tuberculosis were enrolled in the study. Plasma samples were obtained on day 1 (baseline), 3, 7 and 14 of anti-tuberculosis treatment and the levels of tumour necrosis factor-alpha (TNF-alpha) were measured. Patients were classified as either responders or non-responders according to the results of assessment of symptoms and follow-up cultures during the sixth and eighth week of anti-tuberculosis treatment. Thirty consecutive HIV-negative tuberculosis patients were also enrolled in the study. RESULTS The data of a total of 16 AIDS patients (median CD4 cell count 16 x 10(6)/l; 12 responders and four non-responders) and 21 HIV-negative patients (16 responders and five non-responders), whose tuberculosis was culture-proven, were included for analysis. In responders, TNF-alpha levels declined remarkably within the first week of anti-tuberculosis treatment; however, the decline of TNF-alpha levels in non-responders was significantly less [the median ratio of TNF-alpha level on day 7 to that at baseline was 0.32 versus 0.85 (P < 0.001) in AIDS patients; 0.34 versus 0.80 (P = 0.001) in HIV-negative patients). The lack of a > or = 50% reduction in pre-treatment TNF-alpha levels during the first week of treatment was strongly associated with a poor response to anti-tuberculosis treatment (P = 0.001 in AIDS patients; P < 0.001 in HIV-negative patients). CONCLUSION Serial measurement of plasma TNF-alpha levels may help to assess the response to anti-tuberculosis treatment in AIDS patients, in spite of very low CD4 cell counts. Failure of TNF-alpha levels to decline by > or = 50 % of pre-treatment levels in the first week of treatment may be an early surrogate marker of a poor response.

Abstract
Pulmonary diseases remain the most common complication associated with high morbidity and mortality in patients with human immunodeficiency virus (HIV) infection. Invasive diagnostic procedures are often needed to establish a specific diagnosis of pulmonary disease. We report our experience with ultrasound (US)-guided percutaneous transthoracic needle aspiration (PTNA) biopsy in 20 consecutive patients with advanced HIV infection who presented with a variety of pulmonary lesions with or without pleural effusion. A specific diagnosis was established in 16 patients (80%), with infection being the most common etiology. Sputum culture yielded the same causative pathogen in three patients (15%) and all had more than one bacterial or fungal isolates. Mild pneumothorax, the only complication, was observed in two patients (10%) following the procedure. Neither patient required chest tube drainage. Our findings suggest that US-guided PTNA can be a useful and safe alternative to fluoroscopy-guided PTNA in selected HIV-infected patients with focal pulmonary lesions and pleural effusion.

Abstract
An open label, randomized comparative study was conducted to evaluate the safety and efficacy of cefepime, in comparison with ceftazidime, in the treatment of adult hospitalized Chinese patients with severe bacterial infections. Forty patients with severe infections including septicemia, urinary tract infection and bacterial pneumonia were randomly assigned to receive treatment with cefepime (2 g intravenously every 12 h) or ceftazidime (2 g intravenously every 8 h). The cefepime group (20 evaluable patients) and ceftazidime group (16 evaluable patients) were comparable with respect to age, sex, underlying diseases and distribution of infection type. In both groups urinary tract infection was the most common type of infection and Escherichia coli was the most common etiologic microorganism. The rates of satisfactory clinical response were similar in the cefepime and ceftazidime groups (95 versus 93.7%; 95% confidence interval: -0.14 - 0.17, P = 0.87). The bacteriological response rates of the cefepime and ceftazidime groups did not differ significantly (88.9 versus 85.7%; 95% confidence interval: -0.30 - 0.36, P = 0.85). Both cefepime and ceftazidime were well tolerated, with similar incidence of side effects. The results of this study suggest that cefepime is as safe and effective as ceftazidime for the treatment of serious infections in adult hospitalized Chinese patients.
