Predictive value of immature granulocyte in the diagnosis of acute complicated appendicitis.

INTRODUCTION: The goal in appendicitis is early diagnosis and early treatment. Complications develop as treatment is delayed. Therefore, there is a need for fast, low-cost markers that can be diagnosed earlier. The aim of this study is to show the effectiveness of immature granulocyte (IG) level in determining the complication of acute appendicitis. METHOD: In this retrospective cross-sectional study, 99 patients with acute appendicitis and 41 control groups were included in the study. Acute appendicitis patients were divided into two groups as acute simple appendicitis(n = 65) and acute complicated appendicitis(n = 34). In all groups, demographic data, immature granulocyte (IG) count(x103/µL), IG ratio (IG%), white blood cell (WBC), polymorphonuclear leukocytes (PNL), lymphocyte, monocyte, platelet, mean platelet volume (MPV), ferritin levels were recorded. The blood analyses were performed the Mindray BC6800 automated hematology analyzer using standard laboratory protocols. All statistical testing was undertaken using IBM SPSS Statistics for Mac. RESULTS: Compared to the acute simple appendicitis, acute complicated appendicitis patients had significantly higher levels WBC, PNL, monocyte, IG count, and IG% (p = 0.009, p = 0047, p = 0.001, p = 0.018; respectively) while there was no significant difference in ferritin between groups (p = 0.49). In the ROC analysis, AUC value was found for IG count and IG% (0.893 and 0.725, cut-off 0.005 and 0.05; respectively) for acute appendicitis. The negative predictive value of IG for Acute Appendicitis was 85% and was the same as that of WBC. In acute complicated appendicitis, the AUC for IG and IG% was 0.796 (cut-off 0.02) and 0.693 (cut-off 0.2), respectively. Positive Likelihood Ratio (+LR; 2.1) value of IG was found higher than other complete blood count (CBC) tests. CONCLUSION: The IG count is test with fast, more predictive value than another CBC tests, and without cost in the early diagnosis of acute complicated appendicitis. It is strong negative predictive test for Acute Appendicitis disease.

The predictive value of ischemia-modified albumin in the diagnosis of acute appendicitis: A prospective case-control study.

BACKGROUND: Surgical planning is critical for ongoing treatment and prognosis of the disease's course after an appendicitis diag-nosis. Ischemia-modified albumin (IMA) has been used as a biomarker for a variety of ischemia-related disorders in the past. The aim of this study is to determine the IMA level in patients with AA and to evaluate its predictive significance. METHODS: A total of 139 participants were enrolled in the trial. After diagnosis and before surgery, the amount of plasma IMA was tested. Patients diagnosed with appendicitis in Group 1 (n=97) and volunteer surgical patients not diagnosed with appendicitis in Group 2 (n=42) were compared as the final diagnostic criterion. RESULTS: The data of 139 patients with a mean age of 36.15 were evaluated statistically. IMA values were analyzed in both groups. The mean IMA of all patients was 0.74±0.16 AbsU. When the two groups were compared, it was seen that IMA was statistically higher in Group 1 than in the control group. While the area under the curve for IMA was 0.670, the sensitivity for the cutoff value of 0.715 was 68%, the specificity was 62%. CONCLUSION: Our study shows that IMA values provide significant results in predicting acute appendicitis.

Associations Between Bioavailable Vitamin D and Remnant Cholesterol in Patients With Type 2 Diabetes Mellitus.

Introduction In circulation, 99% vitamin D is transported by binding to vitamin D binding protein (VDBP) and albumin. Vitamin D at free form and vitamin D binding to albumin are defined as bioavailable vitamin D. Vitamin D deficiency is associated with atherogenic lipid profile and insulin resistance. Remnant cholesterol is defined as the cholesterol component of triglyceride-rich lipoproteins and contributes to the atherosclerotic burden. The aim of this study was to investigate the association between bioavailable vitamin D and remnant cholesterol in patients with type 2 diabetes mellitus (T2DM). Methods A total of 198 T2DM patients and 208 non-diabetic subjects underwent biochemical measurements of lipid profiles, 25(OH)D, VDBP, CRP and albumin levels. Their demographic characteristics (age, sex) were questioned. Subjects with thyroid, kidney and liver dysfunction and using lipid-lowering therapy were not included in the study. The diagnosis of T2DM was made according to the American Diabetes Association ADA 2016 criteria. Classification of vitamin D levels was done according to the Endocrine Society. Bioavailable vitamin D concentrations were calculated. Results High-density lipoprotein cholesterol (HDL), 25(OH)D, free vitamin D and bioavailable vitamin D levels were significantly lower in diabetic patients than in non-diabetic patients while triglyceride, remnant cholesterol and CRP levels were found to be significantly higher. VDBP was positively correlated with CRP and remnant cholesterol in diabetic patients, but not in non-diabetic patients. Cut-off values were determined from non-diabetics as 3.56 ng/mL for bioavailable vitamin D and 26.56 mg/dL for remnant cholesterol. Logistic regression analysis in the control group showed that the odds ratio for increasing remnant cholesterol above the cut-off value was determined as 2.01 for low bioavailable vitamin D and 1.1 for elevated CRP. However, in T2DM there was no significant relationship. In all subjects, low bioavailable vitamin D increased the remnant cholesterol above the cut-off by 2.18-fold independent of the presence of T2DM. However, there was no significant risk to increase remnant cholesterol, considering a total 25(OH) D deficiency in all groups. Conclusions Low bioavailable vitamin D was found to be a risk factor for elevated remnant cholesterol. This relationship was not detected in patients with T2DM. We believe that the inflammation observed in Diabetes Mellitus may increase the concentrations of VDBP and a decrease in bioavailable vitamin D levels. Therefore, measuring VDBP and calculating the bioavailable vitamin D may provide additional information about the actual vitamin D status.
