Respiratory perspective of COVID-19 in pregnancy.

The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a global pandemic in March 2020 by the World Health Organization (WHO). By February 2022, the disease had infected more than 500 million people globally. COVID-19 frequently manifests as pneumonia and mortality is mainly caused by acute respiratory distress syndrome (ARDS). Previous studies have reported that pregnant women are at a higher risk of SARS-CoV-2 infection and complications can happen due to alterations in the immune response, respiratory physiology, hypercoagulable state, and placental pathology. Clinicians face the challenge of selecting the proper treatment for pregnant patients with different physiological characteristics compared with the non-pregnant population. Furthermore, drug safety for both the patient and the fetus should also be considered. Efforts to prevent COVID-19, including prioritizing vaccination for pregnant women, are essential to break the chain of COVID-19 transmission in the pregnant population. This review aims to summarize the current literature regarding the effect of COVID-19 in pregnant women, its clinical manifestations, treatment, complications, and prevention.

Correlation expression Toll-like receptor 4 with multidrugs resistant tuberculosis in diabetes mellitus condition.

BACKGROUND: Toll-like receptor (TLR) are ligand homologous protein in the APC cell membrane that has functions as a receptor to triger leukocytes and innate immune responses. When there is a Microbacterium tuberculosis (MTB) infection enters from droplets to the lungs, the alveolar macrophages perform a phagocytic function. The interaction between M. tuberculosis and the TLR macrophage receptors produces chemokines which induce migration of monocytes and dendrite cells for destruction. Diabetes militus (DM) has become risk factor for developing tuberculosis. DM condition will reduce immunity and the ability of immune cell phagocytes bactery and triger severe infections. The consequences of more severe infection and metabolic disorders that occur make a person more likely to experience Multidrugs resistant MTB. Not much data that reports on the expression of TLR4 as a ligand that triggers an immune response in conditions of MDR and DM. We try to find out correlation between TLR-4 in MDR MTB, diabetes and level of MTB bacteria in experimental animals. METHODS: We conducted an experimental study on 30 experimental mice weighing 25 grams consisting of negative control grub, infected with MTB, infected with MDR MTB, negative control diabetes, MTB DM, MDR MTB DM. DM animals were induced by streptozosin to experience DM, then in the treatment of infection, intraperitoneal MTB and MDR MTB bacterial injections were given. Termination was carried out on day 14. We count number of bacteria level in the lungs and perform evaluation TLR4 from blood sampel. RESULTS: The negative control group had mean TLR value of 1.47 (± 0.46) while the MTB group showed an increase in TLR 9.22 (± 0.39) followed by MDR MTB 9.50 (± 0.29), DM negative control 9, 21 (± 0.24) and more increasing in conditions of DM MTB 13.36 (± 0.32) and DM MDR MTB 13.35 (± 0.34). ANOVA analysis showed a significant difference (P = 0.00). pearson correlation analysis find strong correlation TLR4 in MTB and MDR MTB with diabetes. CONCLUSION: there were a significant difference level TLR4 between MTB and MDR TB infection with diabetes. higher TLR4 level higher in DM MTB, DM MDR MTB. TLR 4 strong correlates with an increase in the number of MTB bacteria.

Distribution and antibacterial susceptibility pattern of isolated bacteria from endotracheal aspirates among ventilator-assisted pneumonia patients in Indonesia.

An accurate and timely identification of causative microorganisms as well as determination of their antibiotic susceptibility patterns will help in the selection of proper antibiotics and prevention of their misuse in pneumonia patients. The aim of this study was to determine the distribution and antibiotic susceptibility pattern of bacteria isolated from endotracheal aspirates of ventilator-assisted pneumonia patients in Indonesia. A retrospective cross-sectional study was conducted at Dr. Zainoel Abidin Hospital, a provincial reference hospital in Banda Aceh, Indonesia, from January to December 2021. Ventilator-assisted pneumonia patients aged ≥17 years treated in the hospital were considered eligible. Antibiotic susceptibility was valuated using Kirby-Bauer disc-diffusion followed with VITEK 2 Compact. We included 57 patients of which 73.7% males and 26.3% aged 56-65 years (represent the majority group of the patients). Each patient reported at least one comorbidity and the average duration of receiving mechanical ventilation was 8.68 days, and more than half (59.7%) of the patients had a poor clinical outcome (died). A total 57 bacteria isolates (consisting nine species) were recovered; 68.5% Gram-negative and 31.5% Gram-positive bacteria. Among 57 patients, Acinetobacter baumannii was the most frequent isolated Gram-negative bacteria (19.3%), followed by Klebsiella pneumoniae (17.5%), Pseudomonas aeruginosa (15.8%), and Achromobacter denitrificans (12.3%). A. baumannii exhibited <70% sensitivity to aminoglycoside and carbapenem antibiotics and 100% resistance to third-generation cephalosporins. The most abundant Gram-positive bacteria was Staphylococcus aureus (17.5%), followed by S. haemolyticus (10.5%) and S. epidermidis (3.5%). All S. aureus were sensitive to linezolid, tigecycline, vancomycin, and macrolide antibiotics (azithromycin, clarithromycin, clindamycin, and erythromycin), whereas 50% were sensitive to some beta-lactams. However, 50% of S. aureus were methicillin resistant S. aureus (MRSA). Given the magnitude of multi-drug resistance, an empiric antimicrobial therapy in particular to specific settings and implementation of antibiotic stewardship programs are crucial.

Analysis of CD4 and CD8 expression in multidrug-resistant tuberculosis infection with diabetes mellitus: An experimental study in mice.

BACKGROUND: Tuberculosis (TB) remains a major global health problem, in the top 10 causes of death. As a regulator of the immune response, T-helper (Th) cells activate other lymphocytes from the immune system, such as B cells, to destroy the TB pathogen by releasing CD4 and CD8 Th cells. Diabetes mellitus (DM) is a known cause of developing active pulmonary TB. Few studies have examined the biomolecular expression affecting Mycobacterium tuberculosis (MTB) and multidrug-resistant (MDR) MTB, which are associated with low immunity represented by TB in diabetes and CD4 and CD8 levels. MATERIALS AND METHODS: This animal study used a post-test control group design. We performed an experimental study using 30 BALB/c mice, each weighing 25 g. It included six experimental animal groups, of which three had a diabetes condition induced using intraperitoneal streptozotocin, and all were infected with MTB or MDR TB. We evaluated the CD4 and CD8 levels in each group and analyzed the differences. RESULTS: We found a significant difference in CD4 and CD8 levels in MTB and MDR TB conditions. CONCLUSION: This study shows that acute infection in experimental mice with MTB and MDR TB with or without diabetes had the highest levels of both CD4 and CD8 cells, which can be a sign of increased cellular immunity in a mice model.

Outcomes of Daily Dose versus Part-daily Dose Treatment for Lung Tuberculosis: A Real-World Database Study in an Indonesian Hospital.

BACKGROUND: a meta-analysis of randomized control trials (RCTs) on category I pulmonary tuberculosis (PTB) treatments showed that either part-daily (2RHZE/4R3H3) or daily dose (2RHZE/4RH) had the same failure and recurrence rates. However, the World Health Organization (WHO) concluded that the part-daily dose had higher failure and recurrence rates. Therefore, this study was conducted to compare the treatment outcomes between both regimens, whether daily dose regimen has a better treatment outcome than part-daily dose regimen, and the adverse effects between both regimens. METHODS: this was an analytic cross-sectional study of patients at the Persahabatan General Hospital, over the period of January 2015-June 2018. Data were taken from medical records and supported by telephone interviews, each regimen group had 175 patients. RESULTS: there were no significant differences for success rates (p=0.470), lost to follow up rates (p=0.659), failure rates (p=1.000), death rates (p=1.000), and adverse effects in the continuation phase (p=0.324) between the groups. There were, however, significant differences in cure rates (p < 0.001) and complete treatment rates (p<0.001) between the groups. CONCLUSION: the cure rate and complete treatment rate were found to be better for the part-daily than the daily doses. The success rate of both regimens were the same as Indonesia's target (90%). In the continuation phase, there were no significant difference of adverse effects between both regimens.

Chronic Pulmonary Aspergillosis in Post Tuberculosis Patients in Indonesia and the Role of LDBio Aspergillus ICT as Part of the Diagnosis Scheme.

Chronic pulmonary aspergillosis (CPA) is a common sequela of pulmonary tuberculosis (TB). The diagnosis of CPA is difficult and often misdiagnosed as smear-negative TB in endemic settings. Aspergillus IgG detection is the cornerstone of CPA diagnosis. There are a lack of studies on the prevalence of CPA in GeneXpert/smear-negative TB patients in Indonesia, despite a high number of TB cases. This study aims to determine the CPA rate in HIV-negative, GeneXpert-negative patients presenting with symptoms following completion of TB therapy and to evaluate the performance of LDBio Aspergillus immunochromatographic technology (ICT) lateral flow assay in the diagnosis of CPA. CPA was diagnosed on the basis of symptoms for ≥3 months, characteristic chest imaging and positive Aspergillus culture. Twenty (22%) out of 90 patients met the criteria for CPA. The LDBio test was positive in 16 (80%) CPA patients and in 21 (30%) non-CPA patients (p < 0.001) with 80% sensitivity and 70% specificity. Logistic regression revealed a positive LDBio Aspergillus ICT result, smoking history and diabetes to be important predictors of CPA diagnosis. Although CPA is an unrecognised disease in Indonesia, this study suggests that more than one in five GeneXpert negative patients with persistent symptoms following completion of TB therapy may have CPA.

Discordance Between Clinical Status and Chest X-Ray (CXR) in COVID-19 Patient with Asymptomatic Transmission in Jakarta.

Coronavirus Disease 2019 (COVID-19) symptoms are highly various in each patient. CXR are routinely used to monitor the disease progression. However, it is not known whether chest X-Ray (CXR) is a good modality to assess COVID-19 pneumonia.Male, 55 years-old, with pneumonia caused by COVID-19. Discordance was found between patient's clinical status and CXR lesion. On the 7th day of symptoms, patient was clinically well despite severe lesion shown on CXR. On the following day, patient clinically deteriorated despite the improvement on CXR lesion.Improvement of CXR does not always correlate well with patient's clinical status. Clinician have to be careful when using CXR to monitor patient with COVID-19 pneumonia.

Comparative Effectiveness of Tuberculosis Treatment Daily versus Intermittent Regimen in Indonesian TB-DM Patients: Real World Patient Database Study.

BACKGROUND: diabetes mellitus (DM) increases the risk of active TB by three times; there is no specific treatment strategy for tuberculosis-DM (TB-DM) patients. The 2017 WHO guidelines no longer recommended an intermittent regimen in the advanced phase of TB treatment due to higher risk of failure, relapse, and drug resistance compared to the daily regimen. This study aims to compare the effectiveness of treatment, in terms of clinical response and sputum conversion, of TB-DM patients in the advanced phase between the two-treatment delivery schedules. METHODS: a retrospective cohort study from the medical records of patients from 1 January 2015 to 31 December 2018 at Persahabatan Hospital, Jakarta. The inclusion criteria are TB-DM patients aged >18 years with non-reactive HIV test, who have entered the advanced phase of category 1 TB treatment with smear positive at the time of diagnosis. RESULTS: a total of 72 patients met the inclusion criteria. (75% male and 88.8% had at least 1+ smear results at the time of diagnosis). Thirty subjects still have positive smear at the beginning of the advance phase of treatment. After the advanced phase, 44.2% in the intermittent and 41.4% in the daily group were curedhaving sputum conversion. Seven subjects had side effects; but there were lots of dropouts and it is unclear whether they dropped because of side effects or not. CONCLUSION: there is no difference between sputum conversion profile and treatment success in advanced phase TB-DM treatment category 1 between the daily and intermittent regimen.ly for diabetic patients.
