Background: Among the total healthcare waste generated from health-related activities, 10–20% is considered haz ardous, posing significant threats to both the environment and human health. Approximately 3% of healthcare waste is pharmaceutical waste. In Ulaanbaatar city, an estimated 2.65 tons of healthcare waste is generated daily (0.78 tons of medical waste and 1.87 tons of general waste). With the continuous increase in pharmaceutical consumption, the improper disposal of pharmaceutical waste has emerged as a major environmental concern, adversely affecting nature, animals, and the food chain. Contamination from pharmaceutical waste, such as the development of antibiotic resistance, is closely linked to inadequate public awareness of waste management. Aim: This study aimed to assess the knowledge, skills, and attitudes of pharmacy technicians in community pharmacies regarding pharmaceutical waste management. Materials and Methods: A cross-sectional survey was conducted among pharmacy technicians across Mongolia. As of 2023, there are 4,959 licensed pharmacy professionals in the country. Using a representative sampling method, data were collected from 360 pharmacist and pharmacy technicians. Data were analyzed using MS Excel and SPSS version 26. Results: A total of 360 pharmacists from both urban and rural areas participated in the study. The assessment was based on a 5-point Likert scale, with scores of 1-2 considered negative and 3–5 considered positive. The average scores for knowledge, skills, and attitudes were 3.3, 3.06, and 3.25 respectively. While individual scores were satisfactory, the results of questions targeting social awareness were relatively low. Conclusion The knowledge, skills, and attitudes of pharmacy technicians regarding pharmaceutical waste management were found to be satisfactory. However, to further improve knowledge levels, it is recommended to implement additional training programs related to pharmaceutical waste management among pharmacy technicians.

Background: Hepatocellular carcinoma (HCC) is a primary liver cancer originating from liver cells, classified as a chronic liver disease. This cancer ranks third in the world in terms of mortality rate. The MELD (Model for End-Stage Liver Disease) and Child-Pugh scoring systems are utilized to assess the prognosis of chronic liver diseases. Based on studies suggesting that certain blood test indicators, particularly red cell distribution width (RDW), could be used to predict the prognosis of liver cancer and other cancers, as well as serve as diagnostic markers, this topic was chosen to evaluate the clinical significance of RDW in hepatocellular carcinoma. Aim: The aim is to study some blood test indicators and compare them with the MELD score and Child-Pugh score systems in order to determine the prognosis of chronic liver diseases. Materials and Methods: A retrospective, single-center, cross-sectional study was conducted at Mongolia-Japan Hospital. Among 322 patients diagnosed with HCC, 24 patients were selected for the case group, and 37 patients with liver cirrhosis were included in the control group. Results: According to the research criteria, 61 patients were selected and divided into 3 groups, and statistical analysis was performed. In the detailed blood test, platelet count and WBC count showed statistically significant differences among the 3 groups (p< 0.024). In the biochemical tests, C-reactive protein (CRP) was p< 0.018, total bilirubin p< 0.001, and the mean albumin level p< 0.015, all showing statistically significant differences among the 3 groups. A statistically significant inverse correlation was observed between RDW-CV and the clinical MELD score (r=-0.356). Conclusion Platelet count, RDW, CRP, total bilirubin, and average albumin levels are significantly different across the studied groups. RDW-CV shows a moderate inverse correlation with MELD scores, suggesting its potential as a prognostic marker in chronic liver diseases. Further research with larger sample sizes is recommended to confirm these findings.

Introduction: Coronavirus infection 2019 (Ковид-19) is an infection caused by a novel virus and induces severe ARDS. КОВИД-19 pandemic has rapidly spreaded in 221 countries, 245,373,039 cases and 4,979,421 mortalities have been reported. Pulmonary and renal thrombotic angiopathy occur in patients with complications of ARDS, sepsis, and multi-organ failure. Elevated D-dimer in КОВИД-19 patients has been reported firstly by doctors in Wuhan, China. In addition, many studies have revealed that elevated D-dimer has been associated with the severity of the diseases, an increased rate of poor prognosis. Objective: We aim to determine D-dimer in КОВИД-19 patients, and patient condition a decrease of D-dimer level after administration of anticoagulant therapy. Case report: We introduce a rare case of КОВИД-19. Laboratory test results and the effect of anticoagulant therapy have been evaluated during the infection. 85 aged women were admitted with a diagnosis other than КОВИД-19. PCR for SARS-Cov-2 was negative on the previous day of admission, and Sars-Cov-2 Ag rapid test was also negative on the admission day. However, the D-dimer test result was much higher with 7120 ng/мл and X-ray and CT revealed a similar pattern to the КОВИД-19 patient. Then anti-Sars-Cov-2 test was positive with 4,08 COI. Based on laboratory test results of D-dimer, LDH, CRP, and CT pattern the patient was diagnosed with post-КОВИД-19 pneumonia, and anticoagulant therapy was initiated additionally to prevent hypercoagulation induced by КОВИД-19. D-dimer test taken before administration of anticoagulant therapy increased more to 10910 ng/мл. 3 days later D-dimer level decreased to 8180ng/мл and the patient’s condition was improved. Conclusion The evaluation of D-dimer of the patients with КОВИД-19 is highly significant. Anticoagulant therapy might be necessary for КОВИД-19 patients with high D-dimer level in serum. Further studies are needed to assess the long-term outcome of the illness and mortality.

Introduction: Determining stages of liver fibrosis in chronic liver disease is essential for clinical practice such as decision making on medical treatment, setting the interval of follow-up examination for its complication, screening intervals for hepatocellular carcinoma. Goal: We compared non-invasive fibrosis markers among the patients with chronic hepatitis Delta. Materials and Methods: Totally 70 patients with chronic hepatitis D enrolled into this study. The blood samples were examined for complete blood count, liver function test and serum M2BPGi level. Non-invasive markers such as AAR, APRI, Fib-4 scores were calculated. Those with AAR >1, APRI >0.7, FIB-4 >1.45 were considered with advanced fibrosis. All patients underwent liver stiffness measurement using FibroScan M2 probe. The cutoff values of FibroScan for advanced fibrosis were 9 kPa for patient with normal transaminase level and 11 kPa for patients with elevated transaminase. Results: Advanced fibrosis was observed in 25.7%, 38.6% and 38.6% by AAR, APRI and Fib-4 score, respectively. When cut-off levels of serum M2BPGi for advanced fibrosis was 2.2 COI, 35.7% had advanced fibrosis. FibroScan tests showed 34.4% had advanced fibrosis. The AUROC of M2BPGi were 0.894 and 0.827 for predicting advanced fibrosis and liver cirrhosis. Conclusion Serum M2BPGi and FibroScan would be reliable diagnostic tool for identifying liver fibrosis in Mongolian patients with chronic hepatitis D.

Research of function of vitamin D on immune system has been studying since the study revealed that vitamin D receptor is expressed on the surface of the immune cells. 1,2-dihydroxyvitamin D3 [1,25(OH)2D], physiologically active form, can be generated through hydroxylation of 25-hydroxyvitamin D3 [25(OH)D], inactive form of vitamin D, in a liver, connecting with specific VDR make biological action. Vitamin D make different biological actions depends on connecting with different immunological cells. Some studies indicated that Vitamin D plays pivotal role in antibacterial innate immune responses through regulating reaction of the main cells as macrophages and dendritic cells. Moreover, calcitriol, the active form of vitamin D, is connected with VDRE, modulates the innate immune response through directly inducing expression of catelicithin and β-defensin as antimicrobial peptides, reducing secretion of IL-1b, IL-6, TNF-a, RANKL, COX-2 as proinflammatory cytokines and increasing production of IL-10, an anti-inflammatory cytokine. Vitamin D plays in proliferation and differentiation of T and B cells and regulates the activities of over 500 genes. Vitamin D differently impacts on per se stages of T cells’ proliferation. Vitamin D indirectly mitigates the differentiation from immature B cells to plasma B cells while it directly impacts on regulation of overloaded production of antibodies in plasma B cells. In conclusion, vitamin D modulates the innate- and adaptive immune response through regulation on activation of APCells, proliferation and differentiation of immune cells, secretion of some antibacterial peptides.

Background: Kidney transplantation has being performed in Mongolia since 2006. However there is currently no published data available on long-term graft and patient survival. Objective: Our aim was to assess the long-term graft and patient survival rate correlation with HLA-A-B-DR matching. Methods: We retrospectively analyzed data from 70 adult kidney transplants performed at our hospital from August 2006 through January 2014. The data was retrospectively collected from patient files, including characteristics of the recipient and donor, post transplant features and HLA-A-B-DR DNA based typing results. The Kaplan-Meier method was used to analyze graft and patient survival. Results: The mean patient follow-up period after kidney transplantation was 39,6±25.9 months, and the mean kidney graft follow-up period was 36.6±23.7 months for 70 cases. Overall graft and patient survivals were 52 (74.3%) and 60 (85.7%) respectively in 70 cases. Five-year graft and patient survivals were 23 (67.6%) and 29 (85.3%) respectively in 34 cases. The group with four to six mismatched were found to have a significantly lower 3 and 5-year graft and patient survival (71%; 35%); (80%; 40%) compared to 0 to 1 mismatched group (100%) (p=.030; p=.015). Furthermore we analyzed the association of HLA matching, immunosuppressive therapy and long-term graft survival. We selected CNI mono-therapy group for long-term survival analysis and observed a similar pattern. In mono-therapy group, the group with four to six mismatched were found to have a significantly lower 3 and 5-year graft and patient survival (75%; 30%); (65%; 30%) compared to 0 to 1 mismatched group (100%) (p=.037; p=.001). Conclusion The results showed that graft and patient survival rates were lower compared with results from established centers. Statistically highly significant effect of HLA matching on kidney graft and patient survival rates was found in our analysis. Five years after transplantation the graft survival rate of first adult kidney transplant with 4-6MM was 65-70% lower than that of grafts with 0-1MM. Longitudinal cohort study needed in the future to exhibit an improved transplantation outcome.

Background: However kidney transplantation has being performed in Mongolia since 2006, because of pre-transplant sensitization, ABO incompatibility, hepatitis B and C virus activation many patients are taken kidney transplantation in abroad. The transplantation centers use own immunosuppressive regimens. Objective: Our aim was to assess the immunosuppressive regimens efficacy and toxicity in kidney transplant Mongolian recipients. Methods: We analyzed data from 96 adult kidney transplant recipients who had taken kidney transplantation in different transplant centers from August 2006 through January 2014. There were 3 kinds of regimens Group I Simulect induction with standard triple /FK506/CyA+MMF/AZA+steroid/, Group II Campath-1H induction with CNI monotherapy and Group III Campath-1H induction with standard triple /FK506/CyA+MMF/AZA+steroid/. We retrospectively collected the post-transplant first two years serum creatinine. The study was performed in 2014. The questionnaire was taken and blood samples collected for determination of tacrolimus through level and for other laboratory tests. The primary end point was the first two years serum creatinine, the secondary end points included rejection episodes, blood through level of tacrolimus and some laboratory findings. Results: The post-transplant first two years serum creatinine levels were significantly different in 3 groups. Group III showed similar results compared to Group I. There was not enough data of biopsy proven acute rejection episodes however group II said more rejections occurred. However participants said that rejection occurred in 15 (15.6%) biopsy was done only 3 (3.1%) cases. Blood through level of tacrolimus was significantly different in three groups. Some laboratory findings showed different between three groups. Conclusions A regimen of Campath-1H induction with CNI monotherapy (Group II) may be advantageous for short-term renal function and cost effective but there were more rejection complications and increased creatinine. The regimen of Campath-1H induction 11 with standard triple (Group III) may be advantageous for long-term renal function, allograft survival, but there should consider about infection complications and polycythemia. Simulect induction with standard triple could be best choice but transplantations were performed in experienced centers. The study enrolled few cases and cases which were performed at the beginning of transplant program so many things could influence on the result. The study was compared beginner transplant center with experienced centers. Longitudinal cohort study needed in the future.

Background: De-novo donor and non-donor specific antibodies could be detrimental to the kidney allograft. Kidney transplantation has being performed in Mongolia since 2006. However there is currently no published data available on post-transplant de-novo antibodies and long-term graft survival. Our aim was to determine immunosuppressive drug through level, its combination, de-novo HLA antibodies and its influence on graft survival in different immunosuppressive protocols. Methods: We analyzed data from 56 adult first kidney transplant recipients at our hospital from August 2006 to May 2013. We determined the level of tacrolimus, cyclosporine A, and the presence of pre and post-transplant anti-HLA antibodies. Results: Post-transplant follow up period was 1-8 years. Mean recipient age on transplantation was 33.9±9.1 years. Male 45 (80.4%). Cadaver donor kidney was 5 (8.9%). Mean donor age on transplantation was 39.98±11.13 years. Rejection occurrence was 12(21.4%). Tacrolimus and cyclosporine A through levels were 3-12.8ng/ml and 65- 324ng/ml respectively. Anti-HLA class I antibodies were detected in 17.9% of pretransplantation (n=10) and in 23.2% of post-transplantation (n=13) cases respectively (p=0.607). On the other hand, anti-HLA class II antibodies were detected in 5.4% of pretransplantation (n=3) and in 33.9% of post-transplantation (n=19) cases (p=0,001). We determined anti-HLA class II antibody specificity. Anti-DQ, DR, DP antibodies were 25% ( n=14), 14.3% ( n=8) and 7.1% ( n=4) respectively on all 56 cases. Two (3.6%) patients’ samples were positive on three loci of HLA class II. Six patient samples (10.7%) were positive on two loci. Nine (64.3%) of anti-DQ positive patients have rejected their grafts and begun hemodialysis treatment. All 9 graft rejected recipients were anti-HLA DQ positive and had taken cyclosporine mono-therapy for the first year after transplantation. Conclusion The presence of de-novo anti-HLA class II antibodies, especially de-novo anti-DQ were significantly increased on cyclosporine mono-therapy group following transplantation and negatively affected kidney graft survival. The blood through level of cyclosporine was very variable. The graft survival was better in standard triple regimen. Therefore, it is essential to monitor immunosuppressive drug combinations with drug blood level and anti-DSA antibodies as well as to manage antibody removal therapies such as therapeutic plasma exchange, intravenous immunoglobulin and Rituximab therapy on time. HLA –DQ-DP antigen determination is important for the kidney transplantation.

ABSTRACT. Recurrent aphthous stomatitis, or RAS, is common oral disorder of uncertain etiopathogenesis for which only symptomatic therapy is available. This article reviews the current clinical features of RAS among study patients and the result of therapeutic effects of the herbal preparation Akhizunber. Over the past four years we have treated 61 RAS patients with different clinical forms by herbal preparation Akhizunber or Alumekatin. The distribution of clinical forms RAS RAS among study patients were minor aphthae -75.4%, major aphthae -16.4% and herpetiform ulcers -8.2% respectively. The healing time of treated Akhizunber was in minor aphthae -9.28±4.82 days, major aphthae -14 days and herpetiform ulcers -12 days. Of the total study participants, the patients treated by Akhizunber reported a rapid and complete recovery from RAS during treatment compared with treated patients by Alumekatin. Treatment with herbal preparation Akhizunber can be effective for patients suffering from RAS in any clinic form, regardless of their ulcer number and size.

Introduction: Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. The SOCS1 and SHP2 proteins are negative-feed loop inhibitors of signaling of JAK/STAT and TLRs pathways. Purpose: To determine negative regulator protein activation which is activated through TLR7 ligand/IFN-γ signal transduction in endothelial cells. Methods: We used mouse aortic linear endothelial cell (END-D); protein expressio was detected by western blotting Results: We analyzed a time dependent stimulation effects of negative regulator proteins stimulated by TLR7 ligand/IFN-γ in endothelial cell cultures. Imiquimod of 10 μg/ml treatment of 1 hr was followed by 100 ng/ml IFN-γ stimulation for 1-8hr to analysis of negative regulator SOCS1 and SHP2 protein expression.
In untreated cells, there was low activations of negative regulator SOCS1 and SHP2 proteins. IFN-γ stimulation alone had increased SOCS1 and SHP2 protein expressions, also imiquimod treatment highly elevated SOCS1 and SHP2 expressions. However imiquimod and IFN-γ doubled treatment have decreased activation of negative regulator SOCS1 and SHP2 proteins. These findings suggest SOCS1 and SHP2 proteins are inhibitors in the TLR7 ligand/IFN-γ signaling. Conclusion Negative regulators, SOCS1 and SHP2 strongly suppressed activations of TLR7 ligand/IFN-γ signaling
