No detailed reports regarding extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae are currently available from Indonesia, the fourth most populous country in the world. A survey was carried out to investigate the molecular epidemiology and genetic characteristics of clinical ESBL-producing Escherichia coli and Klebsiella pneumoniae isolates originating from the Dr. Soetomo Academic Hospital in Surabaya, Indonesia, over a 4 month period (January to April 2005). ESBLs were characterized by isoelectric focusing and PCR assays. Clonality of the isolates was assessed by PFGE and repetitive-sequence-based PCR (rep-PCR). Phylogenetic grouping was performed among CTX-M-15-producing E. coli. In total, 73 consecutive non-duplicate ESBL-positive E. coli and 72 K. pneumoniae strains were isolated. The bla_CTX-M-15 gene was found to be highly prevalent (69/73 strains, 94.5%) among the 73 ESBL-positive E. coli isolates. The gene was detected in both clonal and non-clonal isolates, as defined by PFGE and rep-PCR. Sixteen CTX-M-15-positive E. coli could be assigned to a single rep-PCR type and phylogenetic group B2 and belonged to the well-known O25b-ST131 clone. Among the 72 ESBL-positive K. pneumoniae isolates, bla_CTX-M-15 was again the most prevalent ESBL (40/72, 55.6%). Several SHV-type enzymes were also frequently detected: SHV-5 (n = 28); SHV-12 (n = 13); and SHV-2 (n = 6). TEM-type ESBLs were not detected in any of the isolates. Indonesia is another developing country affected by the emergence and spread of bacterial strains harbouring ESBL genes, including the CTX-M-15-producing B2-E. coli O25b-ST131 clone.

Background: Drug-resistant tuberculosis (DR-TB) is the barrier for global TB elimination efforts with a lower treatment success rate. Loss to follow-up (LTFU) in DR-TB is a serious problem, causes mortality and morbidity for patients, and leads to wide spreading of DR-TB to their family and the wider community, as well as wasting health resources. Prevention and management of LTFU is crucial to reduce mortality, prevent further spread of DR-TB, and inhibit the development and transmission of more extensively drug-resistant strains of bacteria. A study about the factors associated with loss to follow-up is needed to develop appropriate strategies to prevent DR-TB patients become loss to follow-up. This study was conducted to identify the factors correlated with loss to follow-up in DR-TB patients, using questionnaires from the point of view of patients. Methods: An observational study with a cross-sectional design was conducted. Study subjects were all DR-TB patients who have declared as treatment success and loss to follow-up from DR-TB treatment. A structured questionnaire was used to collect information by interviewing the subjects as respondents. Obtained data were analyzed potential factors correlated with loss to follow-up in DR-TB patients. Results: A total of 280 subjects were included in this study. Sex, working status, income, and body mass index showed a significant difference between treatment success and loss to follow-up DR-TB patients with p-value of 0.013, 0.010, 0.007, and 0.006, respectively. In regression analysis, factors correlated with increased LTFU were negative attitude towards treatment (OR = 1.2; 95% CI = 1.1–1.3), limitation of social support (OR = 1.1; 95% CI = 1.0–1.2), dissatisfaction with health service (OR = 2.1; 95% CI = 1.5–3.0)), and limitation of economic status (OR = 1.1; 95% CI = 1.0–1.2)). Conclusions: Male patients, jobless, non-regular employee, lower income, and underweight BMI were found in higher proportion in LTFU patients. Negative attitude towards treatment, limitation of social support, dissatisfaction with health service, and limitation of economic status are factors correlated with increased LTFU in DR-TB patients. Non-compliance to treatment is complex, we suggest that the involvement and support from the combination of health ministry, labor and employment ministry, and social ministry may help to resolve the complex problems of LTFU in DR-TB patients.

Objective/Background: The aim of this study was to analyze the detection of nontuberculous mycobacterial (NTM) species derived from sputum specimens of pulmonary tuberculosis (TB) suspects. Increasing prevalence and incidence of pulmonary infection by NTM species have widely been reported in several countries with geographical variation. Materials and Methods: Between January 2014 and September 2015, sputum specimens from chronic pulmonary TB suspect patients were analyzed. Laboratory examination of mycobacteria was conducted in the TB laboratory, Department of Clinical Microbiology, Dr. Soetomo Hospital, Surabaya. Detection and identification of mycobacteria were performed by the standard culture method using the BACTEC MGIT 960 system (BD) and Lowenstein–Jensen medium. Identification of positive Mycobacterium tuberculosis complex (MTBC) was based on positive acid-fast bacilli microscopic smear, positive niacin accumulation, and positive TB Ag MPT 64 test results (SD Bioline). If the growth of positive cultures and acid-fast bacilli microscopic smear was positive, but niacin accumulation and TB Ag MPT 64 (SD Bioline) results were negative, then the isolates were categorized as NTM species. MTBC isolates were also tested for their sensitivity toward first-line anti-TB drugs, using isoniazid, rifampin, ethambutol, and streptomycin. Results: From 2440 sputum specimens of pulmonary TB suspect patients, 459 isolates (18.81%) were detected as MTBC and 141 (5.78%) as NTM species. Conclusion: From the analyzed sputum specimens, 18.81% were detected as MTBC and 5.78% as NTM species. Each pulmonary TB suspect patient needed clinical settings to suspect causative agents of MTBC and/or NTM species; clinicians have to understand the local epidemiological data for the evaluation of causes of lung infection to determine appropriate therapy.

Purpose: Patients with tuberculosis need to religiously take medication daily. However, they experience several side effects from these medications. The main reason for measuring the quality of life is to explain closely related factors that affect the patient’s daily life that have been compromised with illness, while considering a patients’ well-being that has associations with individual characteristics. Patients and Methods: This study included 157 patients with tuberculosis at 5 primary health-care centers and 2 hospitals in Surabaya. Quality of life is determined based on eight domains: general health, pain, social functioning, physical functioning, role limitation due to physical health, role limitation due to emotional problems, energy, and emotional well-being. The research instrument used to measure the quality of life is the RAND-36 Item Health Survey, whereas that used to measure mental distress is the Self-Reporting Questionnaire. Results: Our study results show that, of the eight domains measuring the quality of life, only age exhibited a significant effect on general health (P = 0.018); sex did not significantly affect the quality of life in all domains. The level of education exhibited a significant effect only on role limitation due to emotional problems (P = 0.014). Mental distress demonstrated a significant effect on the quality of life in all domains. Conclusion: There are several factors affecting TB patients’ quality of life. The study found that age, level of education, and comorbidity affect quality of life in several domains. However, mental distress affects quality of life in all domains.

Objective  To characterise commensal Escherichia coli and other Enterobacteriaceae with reduced susceptibility to cefotaxime that were collected in a large survey carried out among 3995 patients and healthy persons in two urban regions on Java, Indonesia, in 2001–2002.Methods  The putative extended‐spectrum β‐lactamase (ESBL)‐producing Enterobacteriaceae were analysed using double‐disk synergy tests, isoelectric focusing, PCR assays, DNA sequencing, and pulsed‐field gel electrophoresis (PFGE).Results  On the day of discharge after five or more days of hospitalisation, at least 95 of 999 (9.5%) patients carried ESBL‐positive Enterobacteriaceae as dominant faecal flora. Six patients were simultaneously colonised with E. coli and Klebsiella pneumoniae isolates with ESBL activity. On admission, only 6 of 998 (0.6%) patients were colonised. Faecal carriage of ESBL‐producing Enterobacteriaceae among healthy persons or persons visiting a public health centre was not detected. The 107 ESBL‐positive strains included 68 E. coli, 35 K. pneumoniae, and four other Enterobacteriaceae. bla_CTX‐M‐15 was the most prevalent ESBL in both E. coli (47.1%) and K. pneumoniae (45.7%), but the E. coli O25b‐ST131 clone was virtually absent. Other ESBL types found were: SHV‐2, ‐2a, ‐5, ‐12, CTX‐M‐3, ‐9, ‐14, and TEM‐19. PFGE revealed extensive genetic diversity among the isolates.Conclusions  In 2001–2002, faecal carriage of ESBL‐producing Enterobacteriaceae as dominant flora in Indonesia was almost exclusively hospital‐associated. The presence of various bla_ESBL genes and the extensive genetic diversity among isolates argue against a single/dominant strain outbreak.
