Initiating a district-based public-private mix to overcome tuberculosis missing cases in Indonesia: readiness to engage.

BACKGROUND: District-based public-private mix (DPPM) is a variant of a relatively new PPM strategy of addressing missing cases in the tuberculosis (TB) care cascade in Indonesia. We aimed to determine the readiness of various stakeholders to engage in implementing the DPPM strategy. METHODS: The research design was sequential exploratory mixed methods. A qualitative study in the first stage was carried out through in-depth interviews, FGD and study documents. Data were analyzed through coding, categorizing, pattern matching and theorizing. The second stage was a survey conducted using instruments built in the first stage. Data were analyzed using Rasch modeling and logistic regression. RESULTS: District TB case detection rate (CDR) has improved from 35% (2018) to 104% (2019). The contribution of private hospitals has increased considerably. However, there were almost none from the private primary healthcare facilities. The substantive theory generated indicates that awareness and concern of the TB problem, TB program comprehension and involvement, and institutional support are behind the readiness of facilities to engage the TB program (the readiness to engage). The measurement results indicate the significant correlation of all dimensions on readiness to engage. Concern of the TB problem and institutional support are variables that influence readiness to engage (p < 0.05). CONCLUSIONS: Engaging private and public facility stakeholders is a challenge for local government. Intervention is through a personalized approach, encourages institutional support of health facilities for the TB program and system approach.

Female Genital Tuberculosis: Clinical Presentation, Current Diagnosis, and Treatment.

Female genital tuberculosis is a disease caused by Mycobacterium tuberculosis infection in the female reproductive tract. The disease burden among women leads to infertility is significant, especially in developing countries. The bacteria can spread from the lung into the reproductive organ through lymphatic or hematogenous. Many patients present with atypical symptoms, which mimic other gynecological conditions. Several investigations are needed to establish the diagnosis. Almost all cases of genital TB affect the fallopian tube and cause infertility in patients and endometrial involvement. Current treatment still relies on antituberculosis therapy with a combination of tubal surgery. The present review describes the epidemiological data, clinical presentation, diagnosis, and currently available treatment to cure the disease and for in vitro fertilization.

Rethinking Antimicrobial Resistance Surveillance: A Role for Lot Quality Assurance Sampling.

Global surveillance of antimicrobial resistance (AMR) is a key component of the 68th World Health Assembly Global Action Plan on AMR. Laboratory-based surveillance is inherently biased and lacks local relevance due to aggregation of data. We assessed the feasibility, sensitivity, and affordability of a population-based AMR survey using lot quality assurance sampling (LQAS), which classifies a population as having a high or low prevalence of AMR based on a priori defined criteria. Three studies were carried out in Medan and Bandung, Indonesia, between April 2014 and June 2017. LQAS classifications for 15 antibiotics were compared with AMR estimates from a conventional population-based survey, with an assessment of the cost of a single LQAS classification using microcosting methodology, among patients suspected of urinary tract infection at 11 sites in Indonesia. The sensitivity of LQAS was above 98%. The approach detected local variation in the prevalence of AMR across sites. Time to reach LQAS results ranged from 47 to 138 days. The average cost of an LQAS classification in a single facility was US$466. The findings indicate that LQAS-based AMR survey is a feasible, sensitive, and affordable strategy for population-based AMR surveys, providing essential data to inform local empirical treatment guidelines and antimicrobial stewardship efforts.

Association Between Arg753Gln and Arg677Trp Polymorphisms of TLR2 Gene with Active Pulmonary Tuberculosis in an Indonesian Population.

BACKGROUND: Toll-like receptor is a pattern recognition receptor (PRR) that recognize pathogen-associated molecular pattern (PAMP) in a microorganism. Macrophages recognize the presence of mycobacteria through Toll-Like Receptor 2 (TLR2) and signaling further lead to the production of cytokines, both proinflammatory TNF-α, IL-1ß, IL-6, IL-12, IL-15, IL-18 and IFN-γ, as well as anti-inflammatory IL4, IL-10 and TGF-ß. TLR2 gene polymorphism is strongly determined by ethnicity and geography. Therefore it is necessary to uncovered the existence and association between Arg753Gln and Arg677Trp TLR2 gene polymorphism with TB susceptibility and its underlying mechanisms in Indonesian population in Bandung West Java. METHODS: analytical observational study with cross-sectional design was conducted in Hasan Sadikin General Hospital Bandung from April 2011 to May 2012. Study population consisted of active pulmonary TB patient with positive AFB smear and Latent TB  to ascertain previous MTb exposure. Polymorphism of gen Arg753Gln and Arg677Trp gene was determined with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods. Plasma levels of IFN-γ, TNF-α, IL-10 and IL-12 were also compared between active and latent TB group. RESULTS: heterozygote Arg753Gln TLR2 gene polymorphism was found in 9 of 86 pulmonary TB subjects (10.5%) but none in the latent TB group. The Arg677Trp polymorphism was not found in both groups. The odds ratio for Arg753Gln existence was 28.07 (p=0.022). No differences in the levels of IFN-γ, TNF-α, IL-10 and IL-12 between active pulmonary TB and latent TB subjects with and without Arg753Gln TLR2 gene polymorphism. Conlusion: Arg753Gln polymorphism of TLR2 gene is a risk factor for active pulmonary TB while Arg677Trp polymorphism is not. The Increased risk is not mediated by the difference in IFN-γ, TNF-α, IL-10 and IL-12 serum levels.

Antimicrobial resistance in uropathogens and appropriateness of empirical treatment: a population-based surveillance study in Indonesia.

Objectives: Urinary tract infections (UTIs) are a common reason for empirical treatment with broad-spectrum antibiotics worldwide. However, population-based antimicrobial resistance (AMR) prevalence data to inform empirical treatment choice are lacking in many regions, because of limited surveillance capacity. We aimed to assess the prevalence of AMR to commonly used antimicrobial drugs in Escherichia coli and Klebsiella pneumoniae isolated from patients with community- or healthcare-associated UTIs on two islands of Indonesia. Methods: We performed a cross-sectional patient-based study in public and private hospitals and clinics between April 2014 and May 2015. We screened patients for symptoms of UTIs and through urine dipstick analysis. Urine culture and susceptibility testing were supported by telemicrobiology and interactive virtual laboratory rounds. Surveillance data were entered in forms on mobile phones. Results: Of 3424 eligible patients, 3380 (98.7%) were included in the final analysis, and yielded 840 positive cultures and antimicrobial susceptibility data for 657 E. coli and K. pneumoniae isolates. Fosfomycin was the single oral treatment option with resistance prevalence <20% in both E. coli and K. pneumoniae in community settings. Tigecycline and fosfomycin were the only options for treatment of catheter-associated UTIs with resistance prevalence <20%, whilst the prevalence of resistance to meropenem was 21.3% in K. pneumoniae . Conclusions: Patient-based surveillance of AMR in E. coli and K. pneumoniae causing UTIs indicates that resistance to the commonly available empirical treatment options is high in Indonesia. Smart AMR surveillance strategies are needed to inform policy makers and to guide interventions.

Improving Diagnostic of Pulmonary Tuberculosis in HIV Patients by Bronchoscopy: A Cross Sectional Study.

BACKGROUND: diagnostic of pulmonary TB in HIV patients is a problem due to non specific clinical features, or radiological appearance. HIV patients with CD4≤200 cells/mL infected with M. tuberculosis have less capacity in containing M. tuberculosis, developing granulomas, casseous necrosis, or cavities. This condition is caused by weakend inflammatory which later reduced sputum production and may cause false negative result. This study aimed to assess differences in the positivity level of acid fast bacilli (AFB) and cultures of M. tuberculosis from non-bronchoscopic sputum (spontaneous and induced sputum) compared to bronchoscopic sputum (bronchoalveolar lavage) in HIV positive patients suspected pulmonary tuberculosis with CD4<200 cells/µL. METHODS: this cross sectional study was conducted in adult HIV patients treated in Hasan Sadikin Hospital with CD4≤200 cells/µL suspected with pulmonary tuberculosis by using paired comparative analytic test. All patients expelled sputum spontaneously or with sputum induction on the first day. On the next day, bronchoalveolar lavage (BAL) was performed. The two samples obtained from two methods were examined by AFB examination with staining Ziehl Neelsen (ZN) and cultured of M. tuberculosis on solid media Ogawa on all patients. Positivity, sensitivity and increased sensitivity of AFB and culture of M. tuberculosis in the non bronchoscopic and bronchoscopic groups were compared. RESULTS: there were differences in the positivity level of AFB with ZN staining between non-bronchoscopic and bronchoscopic groups which were 7/40 (17.5%) vs 20/40 (50.0%) (p<0.001). The differences between the cultures of non-bronchoscopic and bronchoscopic groups were 16/40 (40.0%) vs 23/40 (57.5%) (p=0.039). Bronchoscopic sputum increased the positivity level of the ZN AFB examination by 32.5% (from 17.5% to 50.0%) as well as on culture examination by 17.5% (from 40.0% to 57.5%). CONCLUSION: Bronchoalveolar lavage can improve the positivity level of smears and cultures in patients suspected of pulmonary TB in HIV patients with CD4<200 cells/µL.

Molecular epidemiology study of Mycobacterium tuberculosis and its susceptibility to anti-tuberculosis drugs in Indonesia.

BACKGROUND: Genotyping of Mycobacterium tuberculosis helps to understand the molecular epidemiology of tuberculosis and to address evolutionary questions about the disease spread. Certain genotypes also have implications for the spread of infection and treatment. Indonesia is a very diverse country with a population with multiple ethnicities and cultures and a history of many trade and tourism routes. This study describes the first attempt to map the molecular epidemiology of TB in the Indonesian archipelago. METHOD: From 2008 to 2011, 404 clinical specimens from sputum-smear (SS+) TB patients, age ≥15 years, were collected from 16 TB referral primary health centers (PHC) in 16 provincial capitals in Indonesia. Susceptibility testing to first line drugs was conducted for 262 samples using the agar proportion method as per WHO guidelines. Spoligotyping was done on all samples. RESULTS: Ninety-three of the 404 samples (23 %) were from the Beijing family, making it the predominant family in the country. However, the geographic distribution of the family varied by region with 86/294 (29.3 %) in the western region, 6/72 (8.3 %) in the central region, and 2/72 (2.8 %) in the eastern region (p < 0.001). The predominant genotype in the central and eastern regions was from the East-African-Indian (EAI) family, comprising 15.3 % (11/72), and 26.3 % (10/38) of the isolates, respectively. Drug susceptibility to first-line anti-TB drugs was tested in 262 isolates. 162 (61.8 %) isolates were susceptible to all TB drugs, 70 (26.7 %) were mono-resistant 16 (6.1 %) were poly-resistant, and 14 (5.4 %) were multi-drug resistant (MDR). The proportion of Beijing family isolates in the susceptible, mono-resistant, poly-resistant, and MDR groups was 33/162 (20.4 %), 28/70 (40.0 %), 6/16 (37.5 %), and 3/14 (21.4 %), respectively. Overall, resistance of the Beijing family isolates to any of the first line TB drugs was significantly higher than non-Beijing families [37/71 (52.1 %) vs. 63/191 (33.0 %) (p-value = 0.003)]. CONCLUSION: The distribution of Mycobacterium tuberculosis genotypes in Indonesia showed high genetic diversity and tended to vary by geographic regions. Drug susceptibility testing confirmed that the Beijing family of M.tb in Indonesia exhibited greater resistance to first line anti-TB drugs than did other families.

Efficacy and Safety Profile of Tuberculin Protein Purified Derivative Injection As Immunotherapy For the Treatment of Cutaneous and Anogenital Warts: A Review Article.

Introduction: Various treatments available today for anogenital and cutaneous warts have limitations, including time-consuming, challenging to perform, and the risk of scarring. A new treatment using tuberculin purified protein derivative (PPD) has been developed, which is expected to generate cellular immunity against HPV. Objective: To assess the evidence for the efficacy and safety of PPD treatment for cutaneous and anogenital warts. Materials and methods: A literature search was performed with the keyword-based search on digital libraries, including the National Library of Medicine, Cochrane Controlled Register of Trial, and Google Scholar, using the following terms: anogenital warts, condyloma acuminata, cutaneous warts, human papillomavirus, immunotherapy, and tuberculin purified protein derivative. Original studies on treating cutaneous or anogenital warts with PPD were included. The results were 47 clinical trials and 4 case reports. Most of the research was done in countries with common Mycobacterium tuberculosis infection. The treatment showed good efficacy. Comparative studies showed that the treatment has similar efficacy with other immunotherapies. No significant side effects were reported, with evidence of the safety use on the pregnant population. Conclusion: Based on good efficacy and safety, PPD can be considered an alternative therapy, especially in countries where tuberculosis is frequent.

Evaluation of a real-time PCR assay performance to detect Mycobacterium tuberculosis, rifampicin, and isoniazid resistance in sputum specimens: a multicenter study in two major cities of Indonesia.

Background: Tuberculosis (TB) is one of the major global health issues due to its high mortality rate, especially in low- and middle-income countries. One of the key success points of the TB eradication program is early TB diagnosis, which requires rapid and accurate diagnostic testing. This study aimed to evaluate the performance of a newly developed RT-PCR kit (Indigen MTB/DR-TB RT-PCR) in a routine TB clinical setting. Method: A multi-fluorescence RT-PCR assay was designed and developed to detect regions within IS6110, rpoB, katG, and inhA of the Mycobacterium tuberculosis (MTB) genes. Sputum specimens were obtained from suspected TB patients who visited TB healthcare facilities in two major cities of Indonesia from September 2022 to May 2023. Specimens were assessed using Indigen MTB/DR-TB RT-PCR, acid-fast bacillus (AFB) smear microscopy, MTB culture, and drug susceptibility testing (DST) methods. Fisher's exact test (χ2) was used to analyze the Indigen performance relative to culture methods. Result: The performance of Indigen MTB/DR-TB RT-PCR to detect MTB was assessed using 610 sputum specimens obtained from suspected patients. The overall sensitivity and specificity were 94.12% (95% CI: 90.86-96.48%) and 98.32% (95% CI: 96.20-99.46%), respectively. When the analysis was performed on AFB smear-negative TB subjects (386 subjects), a lower sensitivity level was found at 78.57% (95% CI: 68.26-86.78%), while the specificity level remained similar at 98.34% (95% CI: 96.18-99.46%). The overall performance of Indigen MTB/DR-TB RT-PCR to detect MTB showed substantial agreement with the MTB culture method (kappa value 0.93). In comparison to DST, the sensitivity and specificity levels of Indigen to detect RIF resistance or INH resistance were 78.2% (95% CI: 61.8-90.2%) and 82.8% (95% CI: 64.2-94.2%), respectively, while the specificity level for both groups was at 100% (95% CI, 87.7-100%). Conclusion: Indigen MTB/DR-TB RT-PCR demonstrated reliable performance for TB molecular diagnostic testing and can be implemented in routine TB diagnostic settings.

Characteristics of Respiratory Syncytial Virus Infection in Hospitalized Children Before and During the COVID-19 Pandemic in Thailand.

OBJECTIVES: This study compared the epidemiological and clinical manifestations of patients hospitalized with respiratory syncytial virus (RSV) infection before and during the coronavirus disease 2019 (COVID-19) pandemic at a tertiary care hospital in Chiang Mai Province, Thailand. METHODS: This retrospective observational study utilized data from all cases of laboratory-confirmed RSV infection at Maharaj Nakorn Chiang Mai Hospital from January 2016 to December 2021. Differences in the clinical presentation of RSV infection before (2016 to 2019) and during (2020 to 2021) the COVID-19 pandemic were analyzed and compared. RESULTS: In total, 358 patients hospitalized with RSV infections were reported from January 2016 to December 2021. During the COVID-19 pandemic, only 74 cases of hospitalized RSV infection were reported. Compared to pre-pandemic levels, the clinical presentations of RSV infection showed statistically significant decreases in fever on admission (p=0.004), productive cough (p=0.004), sputum (p=0.003), nausea (p=0.03), cyanosis (p=0.004), pallor (p<0.001), diarrhea (p<0.001), and chest pain (p<0.001). Furthermore, vigilant measures to prevent the spread of COVID-19, including lockdowns, also interrupted the RSV season in Thailand from 2020 to 2021. CONCLUSIONS: The incidence of RSV infection was affected by the COVID-19 pandemic in Chiang Mai Province, Thailand, which also changed the clinical presentation and seasonal pattern of RSV infection in children.

The association between serum hypoxia inducible factor-1α level and urothelial bladder cancer: A preliminary study.

INTRODUCTION: We aim to evaluate the association between serum hypoxia inducible factor (HIF)-1α level and stage and grade of urothelial bladder cancer (UBC). METHODS: A case-control study was conducted at Haji Adam Malik Hospital Medan, Indonesia. Inclusion criteria for case group was subject aged 18 years or older and diagnosed with UBC based on histopathological examination. Control group consisted of gender and age matched healthy subjects. Serum HIF-1α level was determined using ELISA method. Data was analyzed with chi square, Mann Whitney, and independent T tests. RESULTS: A total of 80 subjects were enrolled and divided into case and control groups equally. Most subjects were males with mean age of 69.65 years for case group and 68.25 years for control group. Most subjects had advanced primary tumor and lymph node stages. Only 30% subjects had metastasized UBC. Higher serum HIF-1α level was observed in case group (p < 0.001). Serum HIF-1α level was strongly associated with metastasis stage (p < 0.001), followed by lymph node (p = 0.005) and primary tumor (p = 0. 013) stages. Serum HIF-1α level was not associated with grading (p = 0.134). CONCLUSIONS: Serum HIF-1α level is associated with staging but not grading of UBC.

The Single-Nucleotide Polymorphism (SNP) Validity to Detect Omicron Variants.

Introduction: Mutation of SARS-CoV-2 has generated several variants of concern (VOC) which spread promptly worldwide. These emerging variants affected global strategies to overcome COVID-19. Variants of SARS-CoV-2 are determined by the whole genome sequencing (WGS) assay, which is time-consuming, with limited availability (only in several laboratories). Hence, a faster and more accessible examination is needed. The single-nucleotide polymorphism (SNP) method is one of the options for genomic variation surveillance that can help provide an answer to this challenge. This study aims to determine the validity of the SNP method with PCR to detect omicron variants of SARS-CoV-2 compared with the gold standard, WGS. Methods: This is a diagnostic analysis of 140 confirmed COVID-19 nasopharyngeal samples taken from the Kemayoran COVID Emergency Hospital Laboratory and the West Java Provincial Health Laboratory from April to October 2022. Data analysis was carried out to determine conformity and validity values. Results: Analysis using Cohen's kappa coefficient test showed high conformity between SNP and WGS (p value <0.001; kappa coefficient = 0.948). SNP showed great validity values on omicron BA.1 (90% sensitivity; 100% specificity), omicron BA.2 (100% sensitivity; 99% specificity), and omicron BA.4/5 (99.2% sensitivity; 100% specificity). Conclusion: The SNP method can be a more time-efficient alternative to detect omicron variants of SARS-CoV-2 and distinguish their sublineages (BA.1, BA.2, and BA.4/5) by two different specific gene mutations in combination analysis (ΔH69/V70 and Q493R mutations).

Transcriptional Biomarkers for Treatment Monitoring of Pulmonary Drug-Resistant Tuberculosis: Protocol for a Prospective Observational Study in Indonesia.

Many blood-based gene expression biomarkers for monitoring tuberculosis (TB) treatment have been suggested so far, but promising biomarker results for drug-resistant TB treatment response have not been studied. This protocol presents a prospective observational study in Indonesia to profile the human blood transcriptome for predicting the response to drug-resistant TB treatment, focusing on pulmonary TB, and to adapt the specific RNA signature to the qRT-PCR platform. Longitudinal blood samples will be collected from 44 subjects with rifampicin resistant TB, confirmed by Xpert MTB/RIF, and 52 healthy controls. RNA-Seq will be performed to identify changes in the transcriptome following TB treatment. A discriminative RNA signature will be chosen and translated into a score for use in a quantitative PCR-based assay. This study will provide crucial information to guide the discovery and design of a clinically implementable tool to monitor the response of TB treatment.

Digital Health to Strengthen District-Based Public-Private Mix Tuberculosis Control in Purwakarta District, Indonesia: A Qualitative Research.

This study aimed to explore the problem that occurs in district-based public-private mix tuberculosis (DPPM TB) in the Purwakarta district, and how digital health can help overcome this problem. This study used a qualitative research design. By purposive sampling, 46 informants were selected to be interviewed and 9 informants participated in focus group discussion. Data were collected during January to November 2020 and analyzed using the content analysis technique. Trustworthiness is obtained through the triangulation method and peer debriefing. The problems identified in public and private partnership were the lack of communication and awareness, the under-reporting of TB cases in the private health sector, and the limitation of the existing information system. Communication is important in delivering information about a tuberculosis program, patient referrals, and contact investigation; therefore, digital health is considered as a potential strategy to facilitate that. Digital health must consider ethical issues, avoid redundancy, be user-friendly, and include intervention packages. We conclude that the lack of communication between the public and the private health sectors in TB control was a major problem in DPPM TB. Digital health is needed to ensure the flow of information and communication between the public and the private health sectors.

Female urogenital chlamydia: Epidemiology, chlamydia on pregnancy, current diagnosis, and treatment.

Female urogenital chlamydia is a disease caused by Chlamydia trachomatis infection in the female urogenital tract. It is a common bacterial sexually transmitted disease. The bacteria is transmitted through sexual contact with an infected partner or from mother to newborn during vaginal delivery. The prevalence varies among studies and the number is possibly higher due to the lack of massive screening. Many patients were asymptomatic and still be able to transmit the disease. The undiagnosed and untreated disease could cause pelvic inflammatory disease, which leads to infertility, ectopic pregnancy, and chronic pelvic pain. The prevalence among pregnant women is similar to non-pregnant women, therefore chlamydia screening in pregnant women is highly recommended. The nucleic acid amplification test is the most reliable method for the diagnosis due to high sensitivity. The current treatment is given by prescribing antibiotics.

The Magnitude of Anxiety and Depressive Symptoms Among Tuberculosis Patients in Community Health Centers Setting During the Peak of COVID-19 Pandemic.

Background: Mental health problems can occur in patients with chronic diseases such as tuberculosis, and the stress of a pandemic exacerbates the condition. The study aims to explore the magnitude of anxiety and depressive symptoms in tuberculosis (TB) patients in community health centers (CHCs) settings during the COVID-19 pandemic. Methods: The study design was quantitative and cross-sectional. Subjects were TB patients who were recruited from TB services by doctors in CHCs. TB patients (n=74) were screened for anxiety and depressive symptoms over 4 months. Screening results are uploaded on a cloud-based digital platform and analyzed. Non-TB patients, as a comparison, were recruited and screened from the same cloud-based digital platform (n=245) during the same period. Analysis was carried out using Rasch modeling for data transformation. Data was analyzed then for frequency distribution for both groups and the logistic binaries to measure the burden of the mixed anxiety and depressive symptoms among the TB patient age's sub-group. Results: In both groups, there were 48.9% of mild, moderate, and severe categories of anxiety and 63.9% of depressive symptoms. In the TB-patients group, anxiety occurred at 48.7%, of which 23% were in the moderate and severe categories, compared to 13.4% for non-TB patients. Depressive symptoms were present in 71.6% of the TB patient group, of which 28.4% were in the moderate and severe categories, compared to 15.5% of non-TB patients. TB patients aged less than 20 years experienced moderate-severe anxiety with depressive symptoms simultaneously (mixed) as much as 16.3% or 4.6 times more than those aged over 20 years (p<0.05). Conclusion: Moderate and severe anxiety and depressive symptoms were shown higher in the TB patients' group. Adolescents with TB are more susceptible to mental and emotional disorders.

Antibiotic Resistance in COVID-19 with Bacterial Infection: Laboratory-Based Surveillance Study at Single Tertiary Hospital in Indonesia.

Purpose: Coronavirus disease 2019 (COVID-19) is a new pandemic affecting the respiratory system and caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In addition to the increased use of antibiotics, the length of stay of hospitalized patients affects the risk of bacterial infections among the COVID-19 patients. However, this pandemic has interrupted antibiotic surveillance activity and led to an information gap about the prevalence and characteristics of bacterial infection. This study aims to describe the antibiotic resistance in COVID-19 patients with culture-proven bacterial infection using a laboratory-based surveillance approach. Patients and Methods: A retrospective study with a cross-sectional design was conducted on adult patients that confirmed positive for COVID-19 according to the International Classification of Diseases 10th Revision (ICD-10). From March 2020 to October 2021, data were obtained from the hospital information system and merged with the culture and antibiotic susceptibility test from laboratory information system at Hasan Sadikin General Hospital. The outcome is the prevalence percentage of resistance to selected antibiotics in patients with COVID-19. The resistance percentage is considered high when equal to or more than 20%. Results: There was 2786 adult patient confirmed for COVID-19 according to the ICD-10, and 26.3% (n = 733) of them submitted clinical specimen for culture. The prevalence of bacterial infection among COVID-19 patients was 16.4%, predominating Gram-negative bacteria (GNB). The respiratory specimen dominated the positive growth culture. The GNB were predominantly discovered among the respiratory and non-respiratory specimens. High range resistance to ampicillin-sulbactam (24-100%), ceftriaxone (22-81%), cefotaxime (22-73%) and ciprofloxacin (20-86%) are observed among the GNB. Conclusion: There is high resistance to fluoroquinolone and cephalosporins in identified isolate, commonly used as the first-line empirical treatment for respiratory and non-respiratory infection in Indonesia. The continuous antibiotic surveillance is mandatory and crucial to prevent the long-term effects of the COVID-19 pandemic, particularly bacterial infection.

The Potential Predictive Role of Tumour Necrosis Factor-α, Interleukin-1ß, and Monocyte Chemoattractant Protein-1 for COVID-19 Patients Survival.

Background: Tumour necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß), and monocyte chemoattractant protein-1 (MCP-1) are early phase cytokines often encountered when the body is exposed to severe acute respiratory syndrome-associated-coronavirus-2. TNF-α, IL-1ß, and MCP-1 are pro-inflammatory cytokines critical in the defence response against systemic infection and injury. Therefore, TNF-α, IL-1ß, and MCP-1 are the most aggressive responses to viral infections in the acute phase, so they can be used to determine the survival of coronavirus disease 2019 (COVID-19) patients. Purpose: The study aimed to determine the levels of TNF-α, IL-1ß, and MCP-1 as predictors of survival for COVID-19 patients. Patients and Methods: A prospective cohort study was conducted on confirmed COVID-19 by a reverse-transcriptase-polymerase-chain-reaction (RT-PCR) in 84 adults admitted to the hospital in Indonesia. TNF-α, IL-1ß, and MCP-1 level were measured from serum subjects using the enzyme-linked immunosorbent assay. Results: The results from logistic regression modelling of the survival status of COVID-19 patients based on TNF-α, IL-1ß, and MCP-1 levels were significant (p-value=0.024). The predictors of all cytokines had P Wald <0.05, so the three cytokines could be used simultaneously to predict the survival status of COVID-19 patients. MCP-1 has the most dominant risk relative value (2.76; 95% CI; 2.53-4.68) compared to TNF-α and IL-1ß in predicting patient survival. Conclusion: TNF-α, IL-1ß, and MCP-1 as markers of acute systemic inflammatory cytokines can be measured at the beginning of hospitalisation of COVID-19 patients for early diagnosis of disease severity so that healthcare professionals can determine clinical guidance needs for therapeutic programs.

Analysis of Adrenocorticotropic Hormone and Cortisol Levels in Acute Respiratory Distress Syndrome COVID-19 Patients.

Objective: SARS-CoV-2 infection may cause multiple organ failure. However, scarce information can be found on the impact on the endocrine system. This study was conducted to determine plasma Adrenocorticotropic hormone (ACTH) and plasma cortisol levels in a cohort of COVID-19 patients with Acute Respiratory Distress Syndrome (ARDS). Methods: A prospective cohort study was conducted on COVID-19 patients who manifested ARDS and were admitted to the ICU of Dr. Soetomo Tertiary Hospital, Surabaya, Indonesia. Morning plasma ACTH and plasma total cortisol were measured on 45 recruited patients. The outcome of the patient was justified based on the survivance on days 7th and 30th during the follow-up with groupings of surviving for survived patients and nonsurvive for deceased patients. Results: The ACTH and cortisol median were 1.06 (0.5-64.57) pg/mL and 17.61 (0.78-75) µg/dL, respectively. Both parameters were assembled to allow the allocation of the 45 subjects into the survive and nonsurvive groups. There was a moderate correlation between ACTH and cortisol levels in all groups (r = 0.46, p < 0.002) and particularly ACTH and cortisol levels in COVID-19 patients who survived on the 7th-day and 30th-day follow-up (r = 0.518 and r = 0.568, respectively, with p < 0.05). It is important to note that there was no correlation for an individual parameter, either ACTH only or cortisol only, compared to the outcome among patients with various comorbid. Conclusion: ACTH or cortisol alone has no correlation to the outcome of these patients. Therefore, further study of the potential use of corticosteroid treatments guided by ACTH and cortisol levels in reducing the risk of ARDS warrants further investigation.

Pharmacokinetics and safety/tolerability of isoniazid, rifampicin and pyrazinamide in children and adolescents treated for tuberculous meningitis.

OBJECTIVE: To assess the pharmacokinetics and safety/tolerability of isoniazid, rifampicin and pyrazinamide in children and adolescents with tuberculous meningitis (TBM). DESIGN: Prospective observational pharmacokinetic study with an exploratory pharmacokinetic/pharmacodynamic analysis. SETTING: Hasan Sadikin Hospital, Bandung, Indonesia. PATIENTS: Individuals aged 0-18 years clinically diagnosed with TBM and receiving first-line anti-tuberculosis drug dosages according to revised WHO-recommended treatment guidelines. INTERVENTIONS: Plasma and cerebrospinal fluid (CSF) concentrations of isoniazid, rifampicin and pyrazinamide were assessed on days 2 and 10 of treatment. MAIN OUTCOME MEASURES: Plasma exposures during the daily dosing interval (AUC0-24), peak plasma concentrations (Cmax) and CSF concentrations. RESULTS: Among 20 eligible patients, geometric mean AUC0-24 of isoniazid, rifampicin and pyrazinamide was 18.5, 66.9 and 315.5 hour∙mg/L on day 2; and 14.5, 71.8 and 328.4 hour∙mg/L on day 10, respectively. Large interindividual variabilities were observed in AUC0-24 and Cmax of all drugs. All patients had suboptimal rifampicin AUC0-24 for TBM treatment indication and very low rifampicin CSF concentrations. Four patients developed grade 2-3 drug-induced liver injury (DILI) within the first 4 weeks of treatment, in whom anti-tuberculosis drugs were temporarily stopped, and no DILI recurred after reintroduction of rifampicin and isoniazid. AUC0-24 of isoniazid, rifampicin and pyrazinamide along with Cmax of isoniazid and pyrazinamide on day 10 were higher in patients who developed DILI than those without DILI (p<0.05). CONCLUSION: Higher rifampicin doses are strongly warranted in treatment of children and adolescents with TBM. The association between higher plasma concentrations of isoniazid, rifampicin and pyrazinamide and the development of DILI needs confirmatory studies.
