Innovative Hematology Analysis Using Menstrual Blood.

Purpose: The main aim of this study was to compare and analyze hematological profiles using menstrual blood, as an alternative to peripheral blood. Patients and Methods: This study used menstrual and peripheral blood samples from women who were menstruating. The design of this research is analytical observational. Results: Menstrual blood can show an overall hematological profile similar to peripheral blood. Data shows the detection of blood component parameters, white blood cells and reticulocytes in MB with a range within and outside normal blood. Data on MB that show higher values (WBC, MCH, MCHC, PLT, RDW-CV, PDW, MPV, P-LCR, PCT, neutrophils, lymphocytes, monocytes, basophils, reticulocytes, LFR, Ret-He) and lower values lower (RBC, HGB, HCT, MVC, RDW-SD, Eosinophils, IRF, MFR, HFR) when compared with peripheral blood controls. The hematological profiles of Menstrual and peripheral blood showed significant differences (p < 0.01) for several parameters, while several other parameters did not show significant differences (p > 0.05) according to the Wilcoxon test. Conclusion: All hematological profile parameters were detected in menstrual blood. The new concept that menstrual blood can be used as a supporting medium for hematological examinations opens up opportunities for developing independent hematological detection tools in productive women.

6-gingerol ameliorates weight gain and insulin resistance in metabolic syndrome rats by regulating adipocytokines.

Metabolic syndrome (MetS) can lead to increase of insulin resistance (IR) and visceral adipose tissue production of adipocytokines. 6-gingerol is known to have antioxidant and anti-inflammatory activities. Aim of this study is to investigate the effects of 6-gingerol on high-fat high-fructose (HFHF) diet-induced weight gain and IR in rats through modulation of adipocytokines. To induce MetS, male Sprague-Dawley rats were fed with a HFHF diet for 16 weeks and at Week 8, single-dose low-dose streptozotocin (22 mg/kg) were intraperitoneally injected. After 8 weeks of HFHF diet feeding, the rats were treated orally with 6-gingerol (50, 100, and 200 mg/kg/day) once daily for 8 weeks. At the end of the study, all animals were terminated, serum, liver, and visceral adipose tissues were harvested for biochemical analysis including the measurements of total cholesterol, triglycerides, HDL-cholesterol, fasting plasma glucose, insulin, leptin, adiponectin, proinflammatory cytokines (TNF-α and IL-6) and liver and adipose tissue histopathology. Biochemical parameters namely serum total cholesterol (243.7 ± 127.6 vs 72.6 ± 3 mg/dL), triglycerides (469.2 ± 164.9 vs 49.3 ± 6.3 mg/dL), fasting plasma glucose (334 ± 49.5 vs 121 ± 8.5 mg/dL), HOMA-IR (0.70 ± 0.24 vs 0.32 ± 0.06), and leptin (6.19 ± 1.24 vs 3.45 ± 0.33 ng/mL) were significantly enhanced, whereas HDL-cholesterol (26.2 ± 5.2 vs 27.9 ± 1.1 mg/dL) and adiponectin level (14.4 ± 5.5 vs 52.8 ± 10.7 ng/mL) were lowered in MetS vs normal control. Moreover, MetS were marked a significant increase in body weight and proinflammatory cytokines. Treatment with 6-gingerol dose-dependently restored all of those alterations towards normal values as well as the accumulation of lipid in liver and adipose tissues. These findings demonstrate that 6-gingerol, in a dose-dependent mode, showed capability of improving weight gain and IR in MetS rats through modulation of adipocytokines.

Preparation of Solid Lipid Nanoparticle-Ferrous Sulfate by Double Emulsion Method Based on Fat Rich in Monolaurin and Stearic Acid.

Ferrous sulfate is one type of iron that is commonly used in iron supplementation and fortification in food products, but it has low stability and an unfavorable flavor, causing its use to be limited. Encapsulation in a solid lipid nanoparticle (SLN) system is one technology that offers stable active compound protection and a good delivery system; however, a solid lipid matrix should be selected which has good health effects, such as glycerol monolaurate or monolaurin. The purpose of this study was to obtain SLN-ferrous sulfate based on stearic acid and fat rich in monolaurin. SLN-Ferrous sulfate was synthesized at various concentrations of monolaurin-rich fat (20%; 30%; 40% w/w lipid) and various concentrations of ferrous sulfate (5%; 10%; 15% w/w lipid). The results showed that the use of monolaurin-rich fat 40% w/w lipid and 15% w/w ferrous sulfate produced the best characteristics with high entrapment efficiency and loading capacity of 0.06%. The Z-average value of SLN was 292.4 nm with a polydispersity index (PI) of 1.03. SLN-ferrous sulfate showed a spherical morphology, where the Fe trapped in the SLN was evenly dispersed in the lipid matrix to form a nanosphere system. Preparation of SLN-ferrous sulfate by double emulsion method based on stearic acid and fat rich in monolaurin effectively encapsulated ferrous sulfate with high entrapment efficiency and good physicochemical properties.

Serious fungal disease incidence and prevalence in Indonesia.

BACKGROUND: Indonesia is a tropical country, warm and humid, with numerous environmental fungi. Data on fungal disease burden help policymakers and clinicians. OBJECTIVES: We have estimated the incidence and prevalence of serious fungal diseases. METHODS: We found all published and unpublished data and estimated the incidence and prevalence of fungal diseases based on populations at risk. HIV data were derived from UNAIDS (2017), pulmonary tuberculosis (PTB) data from 2013-2019, data on chronic pulmonary aspergillosis (CPA) were used to estimate CPA prevalence and likely deaths, COPD data from Hammond (2020), lung cancer incidence was from Globocan 2018, and fungal rhinosinusitis was estimated using community data from India. RESULTS: Overall ~7.7 million Indonesians (2.89%) have a serious fungal infection each year. The annual incidence of cryptococcosis in AIDS was 7,540. Pneumocystis pneumonia incidence was estimated at 15,400 in HIV and an equal number in non-HIV patients. An estimated 1% and 0.2% of new AIDS patients have disseminated histoplasmosis or Talaromyces marneffei infection. The incidence of candidaemia is 26,710. The annual incidence of invasive aspergillosis was estimated at 49,500 and the prevalence of CPA is at 378,700 cases. Allergic bronchopulmonary aspergillosis prevalence in adults is estimated at 336,200, severe asthma with fungal sensitisation at 443,800, and fungal rhinosinusitis at 294,000. Recurrent vulvovaginal candidiasis is estimated at 5 million/year (15-50 years old). The incidence of fungal keratitis around 40,050. Tinea capitis prevalence in schoolchildren about 729,000. CONCLUSIONS: Indonesia has a high burden of fungal infections.

Effect of atorvastatin on subclinical atherosclerosis in virally-suppressed HIV-infected patients with CMV seropositivity: a randomized double-blind placebo-controlled trial.

Background: Persistent immune activation and inflammation in HIV-infection are linked to excess cardiovascular risk and other non-communicable diseases. Periodic asymptomatic CMV-reactivity in HIV infected patients over a lifetime may contribute to non-AIDS defining morbidity. Despite undetectable levels of HIV and CMV, these patients continue to have increased levels of biomarkers and immune activations. Statin administration is thought to reduce subclinical atherosclerosis by decreasing LDL-C levels. It may also add beneficial effects against CMV infection. Methods: We are conducting a double-blind placebo-controlled trial in which patients are randomized to receive either atorvastatin or placebo with a ratio of 1:1. This trial aims to study the effect of atorvastatin in statin-naive virally-suppressed HIV-infected patients with stable ART and CMV seropositivity on carotid intima media thickness (CIMT), tool that evaluates subclinical atherosclerosis. The study recruits 80 patients at HIV integrated care unit of Cipto Mangunkusumo hospital. All eligible subjects have CIMT evaluation as primary outcome, along with flow mediated vasodilatation (FMD), liver fibrosis and steatosis evaluation, fasting lipid, neurocognitive test, community periodontal index (CPI), and residual immune activation as secondary outcomes in 48 weeks. Ethics and dissemination: This study has received an ethical approval from Health Research Ethics Commitee-Universitas Indonesia and Cipto Mangunkusumo Hospital. Before joining the study, all participants fill in an informed consent form. At the end of study analysis, the trial results will be published and disseminated in peer-reviewed journals. Discussion: The main purpose of our study is to evaluate the effect of atorvastatin administration on CIMT changes in statin naïve virally suppressed HIV-infected patients with stable ART and CMV seropositivity Registration: ClinicalTrials.gov ID NCT04101136; registered on 24 September 2019.

Periodontitis and Cytomegalovirus Associate With Atherosclerosis Among HIV Patients After 5 Years on ART.

OBJECTIVES: Atherosclerosis has been linked with periodontitis in the general population and with persistent immune activation and a high burden of cytomegalovirus (CMV) in HIV patients responding to antiretroviral therapy (ART). Here, we assess risk factors for cardiovascular changes in younger HIV patients representative of patient populations in Asia. STUDY DESIGN: HIV-infected adults (n = 82) with <200 CD4 T-cells/µl were examined as they began ART at Cipto Mangunkusumo Hospital, Jakarta, and after 3 months. 32 patients were re-assessed after 5 years, alongside 32 age-matched healthy controls. METHODS: We assessed the community periodontal index of treatment needs, carotid -thickness (cIMT), plasma markers of immune activation (using commercial enzyme-linked immunosorbent assay) and CMV antibodies by in-house enzyme-linked immunosorbent assay. RESULTS: Periodontitis persisted in 16/32 patients after 5 years and was potentiated by greater age (P = 0.03) and poor oral hygiene (P = 0.05), with no effect of smoking, pulmonary tuberculosis, oral candidiasis, or low CD4 T-cell counts (P > 0.05). After 5 years on ART, right and left cIMT were greater in HIV patients with periodontitis (P = 0.02, 0.006, respectively). Moreover, cIMT values were higher in patients with periodontitis (P = 0.05-0.01) than in equivalent controls. Simple linear regressions showed that patients with periodontitis had greater right (P = 0.01) and left (P = 0.004) cIMT than those without periodontitis. Multiple linear regressions showed that periodontitis and CMV antibody levels optimally predicted poor right and left cIMT (Adjusted R = 0.36, P = 0.0013; Adjusted R = 0.40, P = 0.001, respectively). CONCLUSIONS: Our data identify periodontitis and CMV as independent predictors of atherosclerosis in young adult HIV patients.

Active and Persistent Cytomegalovirus Infections Affect T Cells in Young Adult HIV Patients Commencing Antiretroviral Therapy.

Altered T cell profiles have been linked with metrics of persistent cytomegalovirus (CMV) infections in healthy aging and older HIV patients stable on antiretroviral therapy (ART). In this study, we use CMV DNA to identify active infections, and levels of CMV-reactive antibody to assess the persistent burden of CMV in a longitudinal study of 78 young adult patients beginning ART in Jakarta, Indonesia, with <200 CD4 T cells/µL. CMV antibodies, inflammatory markers (C-reactive protein [CRP], soluble interferon-α/ß receptor) and T cell phenotypes were assessed before ART (V0) and after 1, 3, 6, and 12 months (V1-V12). CMV DNA was detected in 41 patients (52%) at V0, irrespective of CD4 T cell counts, gender, age, or plasma HIV RNA. CMV DNA+ patients had higher levels of antibody reactive with CMV Immediate Early 1 (IE-1) at V0 and V12 (p = 0.04), and with CMV lysate at V12 (p = 0.01). Detectable CMV DNA did not align with inflammatory markers, but associated with lower CD4/CD8 ratios until V3. CMV antibody levels correlated inversely with proportions of naive CD4 and CD8 T cells, and directly with proportions of CD57+ and activated memory T cells (CD3+ CD45RA-) after 3-12 months on ART. Overall, active CMV replication is common in HIV patients beginning ART in Indonesia and associates with low CD4/CD8 ratios. Elevated levels of CMV-reactive antibody measured on ART also mark a depletion of naive T cells, accumulation of memory T cells, and may be a stable metric of the burden of CMV.

Immunological and epidemiological factors affecting candidiasis in HIV patients beginning antiretroviral therapy in an Asian clinic.

OBJECTIVES: Oropharyngeal candidiasis (OPC) is common in HIV patients beginning antiretroviral therapy (ART). Here we address the response to ART, and the roles of poor oral hygiene and defects in local innate immunity with a focus on salivary ß-defensins, as they are implicated in control of candidiasis but have not been investigated in this context. DESIGN: ART naïve HIV-infected adults (n=82) with <200 CD4+ T-cells/mm3 attending clinics at Cipto Mangunkusumo Hospital, Jakarta, were examined at the commencement of ART, and 73 were re-examined after 3 months. OPC was detected by clinical examination, and Candida albicans and fungal burdens were determined following culture on CHROMagar and saboroud-dextrose agar (resp). Salivary ß-defensins (-2 and -3) were quantified by ELISA. Healthy control subjects (n=40) matched the patients by age and gender. RESULTS: OPC was evident in 47 patients before ART, and associated with greater fingal burdens. No OPC was detected in healthy controls and culture positivity was rare. ART decreased the prevalence of OPC to 8/73 HIV patients re-examined after 3 months, with reduced total fungal and C. albicans burdens. The incidence of OPC was independent of oral hygiene. Hyposalivation was more common in untreated HIV patients (16%) than after 3 months on ART and was rare in healthy controls. HIV patients were also more likely to have acidic saliva. Salivary ß-defensin-2 was elevated in the presence of C. albicans pseudohyphae and OPC after 3 months on ART, but ß-defensin-3 was not affected by OPC or ART. CONCLUSIONS: ART reduces the prevalence of OPC, and the total fungal and C. albicans burden. Levels of salivary ß-defensin-2 may associate with OPC in HIV patients responding to ART.

Expressions of Collagen I and III in Hypoxic Keloid Tissue.

BACKGROUND: Wound heals itself spontaneously as physiological process. However, in some individuals, small wounds such as parenteral injections or body piercings may cause increased expression of collagen synthesis. The condition is known as keloid. Histopathology of keloid demonstrates extensive tissue proliferation that extends beyond the margin of primary wound. As a result, it develops uncontrolled or excessive fibrogenesis and tremendous source of collagen that still causes clinical problems until now. A wound, no matter how small the size is, will be followed by increased expression of collagen synthesis. Procollagen I and III is one of markers indicating the development of fibrosis. In fibrosis, there is hypoxia, which is characterized by stabilization of HIF-1α. Therefore, our study was aimed to obtain information about expression of collagen I and III in hypoxic keloid tissue. METHOD: The study design was observational descriptive. Keloid specimens were obtained from biopsy and preputium skins as the control specimens were obtained from circumcision. There were 10 tissue specimens for each specimen group. The analysis performed were evaluation of mRNA expression on collagen I, collagen III and HIF-1α using RT-PCR, the evaluation of HIF-1α protein level using ELISA and the expression of collagen I and collagen III protein using immunohistochemistry. Statistically, data was analyzed by unpaired t-test. RESULTS: In keloid with excessive cell proliferation, we found that the expression of procollagen I mRNA increased 35 times and the expression of procollagen III mRNA increased 27.1 times compared to preputium control group (p<0.05). The expression of procollagen I protein in the dermal layer of keloid was 61% and in the preputium was 37% (p<0.05). The expression of collagen III protein in the dermal layer of keloid was 39% and in the preputium was 16% (p<0.05). There was a 5-fold increase on expression of HIF-1α mRNA in keloid tissue compared to those in preputium (p<0.05). The levels of HIF-1α protein in keloid tissue was 0.201 ng/mg protein and the level in preputium was 0.122 ng/mg protein (p<0.05). There was a strong positive and extremely significant correlation between the expression of HIF-1α protein and procollagen III (R=0.744; p<0.05, Pearson), but HIF-1α with procollagen I are weak correlation (R=0.360; p>0.05, Pearson) Conclusion: Expression of collagen I and III have important role in hypoxic keloid tissue characterized by increased expressions. The expression of collagen I and III is associated with stable HIF-1α in keloid tissue.
