BackgroundThe emergence of transmitted drug resistance (TDR) compromises the effect of antiretroviral therapy (ART), resulting in treatment failure of human immunodeficiency virus (HIV) disease. Although more than a decade has passed since ART was introduced into Indonesia, information on TDR is limited. Here, a genotypic study of TDR among ART-naïve individuals was conducted in Surabaya, Indonesia.MethodHIV-1 seropositive participants were recruited from the communities of commercial sex workers and intravenous drug users as well as from the university teaching hospital in Surabaya. Protease (PR) and reverse transcriptase (RT) genes were sequenced in order to conduct HIV-1 subtyping and phylogenetic analysis and to detect TDR. TDR was defined as the presence of at least one surveillance drug resistance mutation on the WHO list or major drug resistance mutations in the International AIDS Society-USA panel.ResultFifty two and 47 of the PR and RT genes, respectively, were successfully sequenced in the 58 samples. HIV-1 subtyping revealed that 86.3% (50/58) of the sequenced samples were classified as CRF01_AE, 8.6% as subtype B, 3.4% as B/CRF01_AE, and 1.7% as A/G/CRF01_AE. TDR of PR inhibitors was not detected in this study. In contrast, TDR of RT inhibitors was detected in 4.3% (2/47) of samples. In addition, minor drug resistance mutations were detected in 98.1% (51/52) and 12.8% (6/47) of PR and RT genes, respectively.ConclusionThis study clarified the predominance of the CRF01_AE strain in Surabaya, Indonesia. The prevalence of TDR was below 5%, indicating that the currently available first-line regimen is still effective in Surabaya. However, the prevalence might be underestimated since we detected only major population of HIV-1 in individuals. Therefore, continuous surveillance is required in order to detect the emergence of TDR in the early phase.Electronic supplementary materialThe online version of this article (doi:10.1186/s12981-015-0046-y) contains supplementary material, which is available to authorized users.

Aim: To explore the circulating plasma miRNA-21 potential as an early detection biomarker by comparing early-stage breast cancer (BG) and healthy control (HG) in Indonesian population. Materials and methods: The enlisted patients were twenty-six adult female early-stage breast cancer patients (stage 1A, 1B, 2A, and 2B) of Airlangga University Hospital from August until October 2019. Sixteen volunteers were recruited as matched healthy subjects. MiRNA-21 expression was quantified by plasma qRT-PCR. Data analysis performed using IBM SPSS Statistics v.24. MiRNA-21 cutoff , sensitivity, and specificity were analyzed using receiver operating characteristic (ROC) curve. Results: The subject includes 26 BG and 16 HG subjects. The miRNA-21 expression in BG group was 3.933 (1.181-11.794) and 0.905 (0.164-4.532) in HG group (4.34 folds; p=0.001), with 1.66 cutoff (92.3% sensitivity; 81.2% specificity). MiRNA-21 expression separated analysis in HG showed a 0.578 times lower expression in menopause subjects [0.651 (0.164-0.414)] compared to pre-menopause [(1.123 (0.758-4.532); p=0.031]. Yet, in BG group 1.729 times higher miRNA-21 expression was observed in menopause subjects (6.021±3.583) compared to pre-menopause subjects (3.500±1.517;p=0.022). Conclusion: Circulating miRNA-21 expression is a potential biomarker for early detection of breast cancer and might act as a breast cancer risk predictor.

Although human immunodeficiency virus type 1 (HIV-1) infection causes serious health problems in Indonesia, information in regard to drug resistance is limited. We performed a genotypic study on HIV-1 integrase derived from drug-naive individuals in Surabaya, Indonesia. Sequencing analysis revealed that no primary mutations associated with drug resistance to integrase inhibitors were detected; however, secondary mutations, V72I, L74I/M, V165I, V201I, I203M, and S230N, were detected in more than 5% of samples. In addition, V201I was conserved among all samples. Most integrase genes were classified into CRF01_AE genes. Interestingly, 40% of the CRF01_AE genes had an unusual insertion in the C-terminus of integrase. These mutations and insertions were considered natural polymorphisms since these mutations coincided with previous reports, and integrase inhibitors have not been used in Indonesia. Our results indicated that further studies may be required to assess the impact of these mutations on integrase inhibitors prior to their introduction into Indonesia.

Breast cancer is still global burden especially for woman with 2.3 million cases every year dan 15% mortality among cancer diseases. In developing countries, most of the cases are diagnosed at terminal stage when metastasis already found. Bone metastasis is the highest among other metastasis sites such as: lung, liver and brain. Bone metastasis will cause hypercalcemia and bone pain as complications.  Both will gradually decrease patient’s quality of life. Comprehensive and holistic management for these complications will reduce deterioration and hopefully increase patient’s quality of life even they were at terminal stage. We describe a 40-year-old woman who got hypercalcemia crisis. Hypercalcemia usually manifest as a consequence of other diseases. Epidemiologically, majority come from metastasis, but can be other diseases, such as multiple myeloma. Interestingly, during medical investigation through her medical history, and physical examination, and laboratory examinations, we conclude that her hypercalcemia crisis was caused by bone metastasis from breast cancer.

Background: To date, coronavirus diseases 2019 (COVID-19) has no definitive treatment. Thrombosis and hypercoagulation may occur in the advanced stage. Further study on how to use anticoagulants is still required to promote the best prognosis. Methods: A cross-sectional study of 110 moderate, 140 severe, and 81 critical patients receiving unfractioned heparin (UFH), low-molecular-weight heparin (LMWH), and fondaparinux was conducted. Data were collected from March 15th to August 31st 2020 at Universitas Airlangga and Husada Utama Hospital. A comparative study of white blood cell (WBC), neutrophils, lymphocytes, neutrophil-lymphocyte ratio (NLR), c-reactive protein (CRP), procalcitonin (PCT), D-dimer, all-cause mortality rate, length of stay, and days of death among three severities of COVID-19 was done. Univariate and multivariate analysis were used to determine the correlation between inflammatory state after anti-coagulant with patients’ mortality. Results: Two deaths occurred in moderate cases, 36 deaths in severe cases, and 70 deaths in critical cases on ventilators. On day 13, moderate and severe groups showed decreased WBC, neutrophils, NLR, CRP, and D-dimer (p < 0.05). NLR, CRP, and D-dimer (p<0.05) in critically ill and ventilated patients decreased. Day-13 evaluation revealed 32.73% decrease of inflammatory markers in moderate group; 32.86% in severe patients; and 16.05% in critically ill, ventilated patients. A significant correlation between day 13 inflammatory status with mortality was seen in moderate and critical cases with a ventilator (r=0.337; p< 0.05 and r=0.25; p 0.05). Inflammatory profile on day 6 (adjusted odds ratio [aOR] = 2.36; p < 0.05) and day 13 ([aOR] = 4.15; p < 0.05) was associated with patients’ mortality. Conclusions: Anticoagulants in COVID-19 patients lower inflammation markers. Evaluating inflammatory status is essential to predict the mortality. Inflammatory markers on day 13, based on the severity of COVID-19 and comorbidities, were associated with mortality in moderate and critical cases.
