Point-of-care testing in diabetes management

Pubblicato online: 02 May 2019
Pagine: 125 - 135

Astratto

Abstract

The prevalence of diabetes mellitus (DM) has rapidly increased over the last decades, reaching epidemic magnitudes, particularly in lowand middle-income countries. Point-of-care (POC) technology enables decision making near or at the site of patient care. Portable blood glucose meters and HbA1c testing are used by the healthcare provider and millions of patients with diabetes to monitor the safety and effectiveness of the diabetes treatment. However, POC capillary blood glucose and POC HbA1c testing are not recommended for diabetes diagnosis. Rather, they have been used for screening diabetes in lowand middle-income countries to decrease the disease burden.

Comparison of Total Bilirubin Values Measured with ABL 735 Blood Gas Analyzer and Roche Cobas C8000 Chemistry Analyzer in Age-Segregated Pediatric Patients

Pubblicato online: 02 May 2019
Pagine: 137 - 145

Abstract

Aim: Measurement of blood bilirubin levels is a crucial analysis because of the toxic effects of bilirubin on brain tissue, particularly in preterm neonates. The aim of this study was to investigate the consistency of the total bilirubin values obtained by the blood gas analyzer and the autoanalyzer.

Material and Methods: In this study, we used total bilirubin data of 407 pediatric patients from Kocaeli University Medical Faculty Education and Research Hospital Central Laboratory System. Total bilirubin data, provided that it was measured simultaneously, was obtained from ABL 735 blood gas analyzer and Roche Cobas C8000 chemistry analyzer. Pediatric patients (neonates, infant and children under 17 years old) were selected retrospectively by year between 2015-2017.

Results: Under a cut-off value (14.6 mg/dL) ABL 735 blood gas analyzer and Roche COBAS C8000 chemistry analyzer had strong correlation (r = 0.939) for total bilirubin measurements. It was found that 2-15 days old neonates give more scattered total bilirubin data by Bland Altman analysis in two measurements. Statistical analysis performed to compare whole total bilirubin data identity between two measurements: correlation coefficient was found r = 0.949 a statistically significant positive correlation (p < 0.001).

Conclusion: According to our analysis which was supported by previous studies in the literature, we can say that the compatibility between the blood gas analyzer (multi-wave-length spectrophotometric technique) and the chemistry analyzer becomes weaker when the total bilirubin levels exceed 14.6 mg/dL.

Reference interval and upper decission limit for serum uric acid – an evidence-based approach on Romanian population using an a posteriori method

Pubblicato online: 02 May 2019
Pagine: 147 - 158

Astratto

Abstract

Introduction. There is accumulating evidence that high normal serum uric acid (SUA) levels of 6-7 mg/dL are associated with cardiovascular morbidity and metabolic syndrome (MetS), hence the need to redefine its upper limit of normal (ULN). We aimed to derive ULN based on statistics and evidence in a representative sample of the population and to observe its relation to MetS components.

Methods. All SUA measurements form a university rheumatology hospital were extracted between January 5th 2010 and March 21st 2018. SUA levels were measured by a single biochemist a unique type of commercially available kit. Follow-up measurements, patients with diagnoses influencing SUA levels and outlying measurements were excluded. ULNs were studied using least square analysis.

Results. Of the 22503 SUA measurements in the database, only 3318 came from normal individuals: 33.3% men (n=1105), 66.7% women (n = 2213). Least square analysis revealed the following SUA reference intervals (RI): 3.43-6.19 mg/dL for the combined sample; 4.44-7.01 mg/dL for men, 3.28-5.56 mg/dL for women. The values corresponding to the 66th percentile of each group presented lower ULNs: 5.36 mg/dL for all, 6.10 mg/dL for men, 4.90 mg/dL for women. The prevalence of hyperuricemia increased from 13.8% (manufacturer’s gender-specific ULN) to 19.9% (derived ULN). Mean SUA levels significantly increased with the number of MetS components.

Conclusion. We recommend that hyperuricemia should be defined using a statistical approach of ULN selection corresponding to the genderand population-specific 66th percentile of data range.

Effects of Interactions among Gene Polymorphisms of the Renin–Angiotensin-Aldosterone System on Hypertension in Turkish People from Southeast Anatolia

Pubblicato online: 02 May 2019
Pagine: 159 - 168

Abstract

Introduction: Hypertension (HT) is characterized by high blood pressure. The reninangiotensin-aldosterone system (RAAS) plays a crucial role in blood pressure (BP) regulation by maintaining vascular tone and the water-sodium balance. We aimed to investigate whether there is any relation between AGT (M235T), ACE (I/D), and AGTR1 (A1166C) genetic polymorphisms and hypertension among Turkish people from Southeast Anatolia.

Method and Results: A total of 210 individuals, consisting of 102 healthy controls and 108 patients with essential hypertension admitted to the Cardiology Department of the Adıyaman University Research and Application Hospital were included the study. DNA isolation was performed from the blood samples via commercial kit. Genotype determination was determined using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Statistically significant differences were found between the control and patient groups in terms of genotype distribution and allelic frequencies of ACE I/D polymorphisms. Significant differences were found in the frequencies of ICM, DCM, DCT, DAT between the patient and control groups.

Conclusions: In this study, we found a significant association of ACE I/D polymorphism with HT, and we showed that the I allele can increase the risk of HT in Turkish people from Southeast Anatolia. Although we did not find any association between independent AGT M235T and AGT1R A1166C polymorphisms and HT, we observed that the DCM, DCT, and DAT haplotypes of ACE/AGT1R/AGT polymorphisms reduced the risk of hypertension, while the ICM haplotype increased it.

Abstract

The aim of this study was to evaluate the prevalence of the Iodothyronine Deiodinase 2 gene Thr92Ala polymorphism in children from West of Romania with congenital hypothyroidism (CH) and association with TSH levels in response to levothyroxine monotherapy.

Genotyping in 50 children with CH and 52 healthy controls was done using real time PCR.

The results showed that there was no statistical difference between the frequencies of genotypes in patients vs. controls. Patients were treated with L-thyroxine and most had normal values for fT3 and fT4. However, high TSH values were found in 21 patients (42%) after treatment. Among patients with high TSH values, AA genotypes were significantly more prevalent (p = 0.044) than TT and AT genotypes. Our results suggest that for the D2 gene Ala92Thr polymorphism, the AA genotype may be detrimental for achieving euthyroidism in patients with CH and levothyroxine monotherapy, therefore polytherapy could be considered as a better approach in these patients.

Is there any association between Serum anti-HSP27 antibody level and the presence of metabolic syndrome; population based case-control study

Pubblicato online: 02 May 2019
Pagine: 179 - 187

Astratto

Abstract

Background: Heat shock protein 27 (HSP27) is an intracellular chaperone constitutively expressed in many cell types including cardio myocytes and endothelial cells. Circulating levels of HSP27 and anti-HSP27 antibody are higher in patients with CVD. Anti-HSP27 antibody concentrations were also reported to be increased in atherogenesis. We aimed to evaluate serum anti-HSP27 antibody titers in individuals with, or without, MetS in the MASHAD study cohort with large sample size in 6,568 subjects.

Methods: Participants with MetS were identified from MASHAD cohort (n=3358) using the IDF criteria, and the control group were those individuals who did not meet these criteria (n=3210). In-house enzyme-linked immune sorbent assay (ELISA) method was used for measuring Anti-HSP27 antibody levels. The two groups were matched for age, sex and smoking habit.

Results: As expected, there were significant differences in height (p= 0.004), waist and hip circumference, weight, BMI, systolic and diastolic blood pressure, TGs, TC, HDL-C, Hs-CRP, glucose, with the presence of diabetes mellitus, hypertension, hyperlipidemia (p<0.001) between the two groups. Serum HSP27 antibody titers did not show significant difference between the groups with and without metabolic syndrome (p= 0.740).

Conclusion: In conclusion, our results revealed serum anti-HSP27 antibody titers were not statistically different between individuals with and without MetS. However, it is possible that drug treatment may affect antibody titers and confound our findings in this population sample..

Systemic interleukins levels in community-acquired pneumonia and their association with adverse outcomes

Pubblicato online: 02 May 2019
Pagine: 189 - 198

Abstract

Introduction: Community-acquired pneumonia (CAP) is still one of the major causes of morbidity and mortality worldwide. Pro-inflammatory and anti-inflammatory interleukins have been studied to elucidate the role that inflammation plays in its pathogenesis. The aim of this study is to investigate inflammation in CAP, by analyzing in dynamic, serum levels of six interleukins (IL) and their predictive value regarding adverse outcomes.

Materials and methods: Forty adult patients with CAP, admitted in the Teaching Hospital of Infectious Diseases, Cluj-Napoca, Romania from December 2015 to February 2017, were enrolled in this study. Serum levels of pro-inflammatory: IL1β, TNF-α, IL-6, anti-inflammatory: IL-10 and IL-4, along with IL-17A were analyzed in dynamic, on day 1 and day 4.The receiver – operator curves (ROC) were used to analyze the outcome prediction of IL.

Results: Serum levels of IL-1β, IL-6, TNF-α and IL-10 have decreased significantly in dynamic, while IL-4 increases. IL-17A has acted like a pro-inflammatory cytokine. We have found a correlation between IL-6 and IL-10 (r=0.429, p=0.000), IL-6 and IL-17A (r=0.295, p=0.008) and IL-10 and IL-17A (r=0.475, p=0.000). Out of 40 patients, 9 had adverse outcomes, consisting in 9 relapses from which 1 died. IL-6 discriminates alone between adverse and favorable outcomes. With multivariate analysis and multiple regression of all combined IL, we have found that there is a predictive model regarding adverse outcomes.

Conclusion: IL-10 and IL-17A behave like pro-inflammatory cytokines. IL-6 is a predictive marker for adverse outcomes alone. All IL studied together have an impact on adverse outcomes.

Seroprevalence and risk factors for hepatitis E virus infection in the Romanian adult population: a cross-sectional study in a tertiary hospital

Pubblicato online: 02 May 2019
Pagine: 199 - 208

Astratto

Abstract

Background: The primary goal was to estimate the seroprevalence of autochthonous hepatitis E virus (HEV) infection in adult Romanian population. Additionally, we aimed to identify the risk factors associated with the HEV seropositive status.

Methods: Between January 2015 and December 2016, 201 adult patients were tested for antiHEV-IgG. Multivariate logistic regression was used to examine for factors associated with a positive HEV-IgG test. The level of significance was set at α = 0.05.

Results: The final analysis included 175 patients who followed the study protocol. Forty-sex (26.3%) had positive, 121 (69.1%) had negative, and 8 (4.6%) had indeterminate antiHEV-IgG results. Patients with positive anti-HEV-IgG were older [median age: 54.5 years (IQR 43-65)] compared to patients with negative anti-HEV-IgG [median age: 37.5 years (IQR 28-57.5)], p <0.001. A positive HEV-IgG was more common in patients with history of blood transfusions [n=10 (22.7%) versus (vs) n=11 (9.4%), p=0.025], in those with immunosuppressive conditions [n=18 (40.9%) vs n=27 (23.1%), p=0.025] and in patients with positive hepatitis B surface antigen (HBsAg) [n=14 (31.1%) vs n=10 (10.3%), p=0.002].

Conclusions: In conclusion, we found that autochthonous HEV seropositivity is common in our study population, especially in older patients, previous blood transfusions, presence of immunosuppressive conditions, and positive HBsAg.

Abstract

Introduction: Rotavirus infection is a major cause of morbidity and mortality in infants and young children with diarrhea throughout the world.

Material and Methods: In this study, we aimed to determine the detection rate of rotavirus infection in 181 children less than 5 years of age presenting with acute gastroenteritis and admitted to a tertiary care hospital in Ankara, Turkey, from April to November 2012. We documented the epidemiological data by elucidating the prevalent genotypes. Stool specimens were collected, and rotavirus antigen in the samples was detected using ELISA. G and P genotypes were determined by RT-PCR via type specific primers. The nucleotide sequence of the concerned genes was determined by Sanger sequencing and phylogenetic analysis was performed by neighbor-joining method.

Results: Of the 181 samples, 28 (15.5%) were positive for the rotavirus antigen. Twenty-seven samples were positive for G genotypes and 21 were positive for P genotypes. Genotypes G1 (7.1%), G2 (7.1%), G3 (7.1%), G4 (3.6%), G9 (71.5%) and P4 (3.6%), P8 (71.4%) were identified. Genotype G9P[8] (50%) was predominant in the combination of G and P genotypes. Most of the G9 strains of this study formed an independent cluster in Lineage III, except two strains which clustered with an Ethiopian G9 strain of 2012.

Conclusions: It seems that during 2012 season, genotype G9P[8] increased significantly in Ankara due to a new circulating strain of G9.

Results: Serum levels of IL-1β, IL-6, TNF-α and IL-10 have decreased significantly in dynamic, while IL-4 increases. IL-17A has acted like a pro-inflammatory cytokine. We have found a correlation between IL-6 and IL-10 (r=0.429, p=0.000), IL-6 and IL-17A (r=0.295, p=0.008) and IL-10 and IL-17A (r=0.475, p=0.000). Out of 40 patients, 9 had adverse outcomes, consisting in 9 relapses from which 1 died. IL-6 discriminates alone between adverse and favorable outcomes. With multivariate analysis and multiple regression of all combined IL, we have found that there is a predictive model regarding adverse outcomes.

Conclusion: IL-10 and IL-17A behave like pro-inflammatory cytokines. IL-6 is a predictive marker for adverse outcomes alone. All IL studied together have an impact on adverse outcomes.

Abstract

Background: The primary goal was to estimate the seroprevalence of autochthonous hepatitis E virus (HEV) infection in adult Romanian population. Additionally, we aimed to identify the risk factors associated with the HEV seropositive status.

Methods: Between January 2015 and December 2016, 201 adult patients were tested for antiHEV-IgG. Multivariate logistic regression was used to examine for factors associated with a positive HEV-IgG test. The level of significance was set at α = 0.05.

Results: The final analysis included 175 patients who followed the study protocol. Forty-sex (26.3%) had positive, 121 (69.1%) had negative, and 8 (4.6%) had indeterminate antiHEV-IgG results. Patients with positive anti-HEV-IgG were older [median age: 54.5 years (IQR 43-65)] compared to patients with negative anti-HEV-IgG [median age: 37.5 years (IQR 28-57.5)], p <0.001. A positive HEV-IgG was more common in patients with history of blood transfusions [n=10 (22.7%) versus (vs) n=11 (9.4%), p=0.025], in those with immunosuppressive conditions [n=18 (40.9%) vs n=27 (23.1%), p=0.025] and in patients with positive hepatitis B surface antigen (HBsAg) [n=14 (31.1%) vs n=10 (10.3%), p=0.002].

Conclusions: In conclusion, we found that autochthonous HEV seropositivity is common in our study population, especially in older patients, previous blood transfusions, presence of immunosuppressive conditions, and positive HBsAg.

Abstract

Introduction: Rotavirus infection is a major cause of morbidity and mortality in infants and young children with diarrhea throughout the world.

Material and Methods: In this study, we aimed to determine the detection rate of rotavirus infection in 181 children less than 5 years of age presenting with acute gastroenteritis and admitted to a tertiary care hospital in Ankara, Turkey, from April to November 2012. We documented the epidemiological data by elucidating the prevalent genotypes. Stool specimens were collected, and rotavirus antigen in the samples was detected using ELISA. G and P genotypes were determined by RT-PCR via type specific primers. The nucleotide sequence of the concerned genes was determined by Sanger sequencing and phylogenetic analysis was performed by neighbor-joining method.

Results: Of the 181 samples, 28 (15.5%) were positive for the rotavirus antigen. Twenty-seven samples were positive for G genotypes and 21 were positive for P genotypes. Genotypes G1 (7.1%), G2 (7.1%), G3 (7.1%), G4 (3.6%), G9 (71.5%) and P4 (3.6%), P8 (71.4%) were identified. Genotype G9P[8] (50%) was predominant in the combination of G and P genotypes. Most of the G9 strains of this study formed an independent cluster in Lineage III, except two strains which clustered with an Ethiopian G9 strain of 2012.

Conclusions: It seems that during 2012 season, genotype G9P[8] increased significantly in Ankara due to a new circulating strain of G9.
