RESUMO

BACKGROUND: Diabetic nephropathy (DN) is a prevalent and chronic, severe complication of diabetes, representing a serious global health concern. Early detection of DN is essential for initiating timely and effective therapeutic interventions and accurately assessing prognosis. Neutrophil Gelatinase-Associated Lipocalin (NGAL), a low molecular weight protein, has emerged as a potential biomarker for DN due to its association with renal injury and its ability to provide early indications of kidney damage. NGAL levels in both serum and urine are elevated in individuals with renal damage, making it a valuable biomarker for detecting early signs of kidney impairment in the context of diabetes. This study aims to investigate the utility of NGAL as an early biomarker for DN and explore its correlation with various clinical parameters associated with the disease. Understanding the relationship between NGAL levels and clinical parameters such as glycemic control, renal function, blood pressure, and duration of diabetes is crucial for comprehensively evaluating the potential of NGAL as a diagnostic and prognostic tool for DN. Furthermore, assessing the sensitivity and specificity of NGAL in detecting early-stage DN will provide valuable insights into its clinical applicability and reliability. METHODOLOGY: A planned meta-analysis was conducted following PRISMA and MOOSE guidelines. The PubMed database was searched from January 2016 to June 2023 for English-language studies on DN and NGAL. Fifteen eligible studies were included as per the criteria. Data on serum NGAL levels in DN patients and healthy controls were analyzed using Stata 16.0 software. RESULT: The study revealed a significantly higher mean serum NGAL level in DN patients (168.08 ng/ml, 95% CI: 105.50-230.67) compared to healthy controls (75.02 ng/ml, 95% CI: 43.02-107.03), demonstrating NGAL's potential as a biomarker (P=0.01). CONCLUSION: NGAL offers a powerful tool for DN diagnosis, staging, and monitoring, surpassing traditional markers in sensitivity. Challenges include defining universal threshold values and ensuring consistent test performance across diverse clinical settings. The study underscores NGAL's potential in transforming DN diagnosis and management.

RESUMO

Background Bone tumors account for 1% of all cancers and have considerable morbidity and mortality. There is a proposed theory of increased oxidative stress characterized by an increased level of reactive oxygen species (ROS) that disrupts the intracellular reduction-oxidation (redox) balance which has been implicated in various diseases including cancer. The aim of the present study was to measure the levels of oxidant stress and antioxidant mechanism in bone tumors (benign as well as malignant).  Methods The study cohort consisted of 42 subjects: 14 malignant bone tumors, 14 benign bone tumors, and 14 healthy controls. Serum Malondialdehyde (MDA) levels were determined to assess oxidative stress while antioxidant status was evaluated using superoxide dismutase (SOD). Results Patients with malignant bone tumors showed a significant increase in plasma MDA levels (p<0.05) while SOD levels were significantly decreased (p<0.05). No significant difference in oxidative damage was noted between both the sarcomas (p>0.05). Conclusions In conclusion, an increase in oxidative stress and a decrease in antioxidant status are observed in bone tumors. Further studies on the manipulation of redox balance in patients with bone tumors can act as a useful approach in early diagnosis or designing management strategies for bone tumors.

RESUMO

BACKGROUND: Bone tumors are responsible for considerable morbidity and mortality at an early age. Malignant bone tumors are quite aggressive in nature. Thus, an accurate and timely diagnosis is essential for bone tumors. Neutrophil gelatinase associated lipocalin (NGAL) and vitamin D have been found to be associated with cancer and may have potential to act as biomarkers for bone tumors also. METHODS: Serum levels of NGAL and 25-OH vitamin D were estimated in 14 patients with benign and 14 with malignant bone tumors and compared with 14 apparently healthy controls. The data collected was compared among different groups using appropriate statistical analysis. NGAL was estimated by enzyme linked immunosorbent as-say (ELISA) and 25-OH vitamin D by radioimmunoassay (RIA) in the serum samples. RESULTS: Serum NGAL levels were found to be increased significantly and 25-OH vitamin D levels decreased significantly in patients with malignant bone tumors as compared to healthy controls (p < 0.001) while this difference was not statistically significant in patients with benign bone tumors (p = 0.05). The difference in serum levels of NGAL and 25-OH vitamin D in patients with malignant bone tumors was found to be statistically significant as compared to patients with benign bone tumors (p < 0.05). The correlation was not statistically significant between the levels of 25-OH vitamin D and NGAL in group I (r = 0.067, p = 0.819), group II (r = 0.204, p = 0.483), and group III (r = -0.086, p = 0.772). CONCLUSIONS: Serum NGAL and 25-OH vitamin D may be used as important serological biomarkers in patients with bone tumors along with other standard investigative modalities.

RESUMO

INTRODUCTION: Neutrophil gelatinase-associated lipocalin (NGAL) has been reported to be unregulated in many cancers and to suppress tumor suppressor genes like p53 leading to cell proliferation. Studies to report its relationship with carcinoma cervix (Ca Cx) are still scant. MATERIALS AND METHODS: Serum NGAL levels were analyzed in 30 patients of histopathologically proven locally advanced Ca Cx at the time of diagnosis and 3 weeks after standard chemoradiation by enzyme-linked immunosorbent assay. These patients underwent either brachytherapy or supplementary external beam radiotherapy (EBRT) depending on the response of treatment. The results were analyzed statistically by applying Student's paired t-test. RESULTS: No statistically significant difference (P > 0.05) was observed in patients of Ca Cx before and after treatment or when compared stage wise, histopathological grade wise, or response wise. But the levels were found to increase when duration of treatment was ≥8 weeks (P = 0.040) and to decrease significantly when duration of treatment was <8 weeks (P = 0.0052). The NGAL levels also increased significantly after treatment in patients who received EBRT and supplementary radiotherapy (P = 0.019) while the pre- and post-treatment difference in NGAL levels was not statistically significant in patients who received EBRT + intracavitary brachytherapy (P > 0.05). CONCLUSION: As the duration as well as modality of treatment is quite important in Ca Cx, shorter duration associated with better results and lower NGAL levels, NGAL might prove to be a useful biomarker although further studies are needed to support the claim.

RESUMO

BACKGROUND: Menopause and hypothyroidism, both individually, affect the reproductive hormone profile as well as body metabolism which is reflected in the form of a deranged biochemical profile. It will be interesting to observe the effects on both these profiles, when menopause is associated with hypothyroidism. METHODS: This study was conducted on 30 postmenopausal women with newly diagnosed primary hypothyroidism and 30 euthyroid menopausal females as controls. Serum samples of all the subjects were analyzed for complete thyroid profile including total T3 (TT3), total T4 (TT4), free T3 (FT3), free T4 (FT4), thyroid stimulating hormone (TSH), estradiol, progesterone, fasting glucose, renal function tests, liver function tests, and lipid profile. Data of both the groups was compared using Student's t-test. RESULTS: There was no statistically significant difference observed between the fasting glucose levels and renal and liver function tests in both the groups (p > 0.05). Serum triglycerides, total cholesterol, low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) were found to be significantly increased (p < 0.05) while high density lipoprotein cholesterol (HDL-C), estradiol, and progesterone were found to be significantly decreased (p < 0.05) in menopausal hypothyroid women as compared to their euthyroid counterparts. CONCLUSIONS: Thus, an association of both menopause and hypothyroidism may lead to accentuation of effect of each on biochemical and reproductive hormone profile.

RESUMO

BACKGROUND: Mortality due to lung cancer is one of the growing concerns worldwide. Accurate and timely diagnosis is the key to treatment of this disease. Neutrophil gelatinase associated lipocalin (NGAL) and vitamin D have been found to be associated with cancer and may have potential to act as biomarkers for lung cancer. METHODS: Serum levels of NGAL and 25 hydroxy vitamin D (25OH vitamin D) were estimated in 25 patients with lung cancer before (Group I) and 4 weeks after standard treatment (Group II) by chemoradiation. The levels were also analyzed in 25 apparently healthy controls and data was compared among different groups using appropriate statistical analysis. NGAL was estimated by enzyme linked immunosorbent assay (ELISA) and 25OH vitamin D by radioimmunoassay (RIA) in the serum samples. RESULTS: Serum NGAL levels were found to be increased significantly in patients before treatment as compared to healthy controls (p < 0.001) while the levels decreased significantly after treatment (p < 0.01). The levels of vitamin D were found to be decreased in lung cancer patients as compared to healthy controls (p < 0.05) while after treatment the levels of vitamin D were found to be significantly increased (p < 0.001). The correlation was not statistically significant between the levels of vitamin D and NGAL in Group I (r = 0.12, p = 0.57), Group IIa (r = 0.037, p = 0.86), and Group IIb (r = 0.091, p = 0.66). CONCLUSIONS: Serum NGAL and vitamin D bear the potential to act as biomarkers in patients with lung cancer.

RESUMO

INTRODUCTION: Vitamin D has been shown to play a vital role in bone mineral homeostasis by stimulating the intestinal absorption of calcium and phosphate. The critical role of Vitamin D in bone metabolism triggered the need to evaluate the effect of Vitamin D deficiency and hence replacement of the same on osseointegration of dental implants. This prospective study evaluated the crestal bone level in patients having low level of Vitamin D treated with dental implant with or without Vitamin D3 supplements. MATERIALS AND METHODS: A prospective clinical study was conducted on 32 patients based on the inclusion and exclusion criteria. Patients were divided into two groups on the basis of Vitamin D level < 30 ng/ml (Group I: patients receiving Vitamin D3 supplements, i.e., cholecalciferol 1 g sachet 60,000 IU/month) or <30 ng/ml (Group II: not receiving Vitamin D3 supplements). The crestal bone level measurements were made with the help of Digimizer Image Analysis, MedCalc software. RESULTS: All implants showed clinically acceptable crestal bone level at interval of 1 week (baseline), 3 months, and 6 months. There was a statistically nonsignificant difference seen for the values between the groups (P > 0.05) for all other values at various time intervals. However, there was a statistically significant/highly significant difference seen for the values between the groups (P < 0.01, 0.05) for 3 months distal with higher values for Group I as compared to Group II. CONCLUSION: From the study, it can be concluded that cholecalciferol has systemic effects on accelerating bone formation around titanium implant.

RESUMO

AIM: To study sigma metrics and quality goal index ratio (QGI). METHODS: The retrospective study was conducted at the Clinical Biochemistry Laboratory, PGIMS, Rohtak, which recently became a National Accreditation Board for Testing and Calibration of Laboratories accredited lab as per the International Organization for Standardization 15189:2012 and provides service to a > 1700-bed tertiary care hospital. Data of 16 analytes was extracted over a period of one year from January 2017 to December 2017 for calculation of precision, accuracy, sigma metrics, total error, and QGI. RESULTS: The average coefficient of variation ranged from 2.12% (albumin) to 5.42% (creatinine) for level 2 internal quality control and 2% (albumin) to 3.62% (high density lipoprotein-cholesterol) for level 3 internal quality control. Average coefficient of variation of all the parameters was below 5%, reflecting very good precision. The sigma metrics for level 2 indicated that 11 (68.5%) of the 16 parameters fall short of meeting Six Sigma quality performance. Of these, five failed to meet minimum sigma quality performance with metrics less than 3, and another six just met minimal acceptable performance with sigma metrics between 3 and 6. For level 3, the data collected indicated eight (50%) of the parameters did not achieve Six Sigma quality performance, out of which three had metrics less than 3, and five had metrics between 3 and 6. QGI ratio indicated that the main problem was inaccuracy in the case of total cholesterol, aspartate transaminase, and alanine transaminase (QGI > 1.2), imprecision in the case of urea (QGI < 0.8), and both imprecision and inaccuracy for glucose. CONCLUSION: On the basis of sigma metrics and QGI, it may be concluded that the Clinical Biochemistry Laboratory, PGIMS, Rohtak was able to achieve satisfactory results with world class performance for many analytes one year preceding the accreditation by the National Accreditation Board for Testing and Calibration of Laboratories. Aspartate transaminase and alanine transaminase required strict external quality assurance scheme monitoring and modification in quality control procedure as their QGI ratio showed inaccuracy.

RESUMO

AIM: To study the levels of neutrophil gelatinase associated lipocalin (NGAL) in head and neck squamous cell carcinoma (HNSCC). METHODS: This was a non randomized case control study conducted at Department of Biochemistry, in collaboration with Regional Cancer Center over a period of one year. The study population included 50 adult newly diagnosed HNSCC patients reporting in outpatient department at Regional Cancer Center and compared with 50 healthy controls. NGAL was estimated by ELISA technique. Student t test and χ2 test were applied for comparison of means of study groups. Correlations between groups were analyzed using Pearson correlation coefficient (r) formula. RESULTS: Patients with HNSCC exhibited significantly increased levels of NGAL (P < 0.05) as compared to healthy controls (978.88 ± 261.39 ng/mL vs 34.83 ± 7.59 ng/mL). Out of 50, 26 patients (52%) were in stage IV, 21 (42%) in stage III, 1 (2%) patient in stage II and 2 (4%) patients were in stage I. Metastasis was absent in 98% patients and mean NGAL levels were highest in these patients but P value was not significant. Mean NGAL levels were highest in stage IV [1041.54 ± 222.15 ng/mL (stage IV) vs 1040 ± 0.00 ng/mL (stage I); 900 ± 0.00 ng/mL (stage II) and 1031.90 ± 202.55 ng/mL (stage III)] and χ2 test was highly significant (P < 0.001). Thirty-six patients (72%) were having moderately differentiated HNSCC and mean NGAL levels were maximum in patients with well differentiated HNSCC (1164 ± 315.64 ng/mL vs 1013.33 ± 161.19 ng/mL in moderately differentiated and 890 ± 11.55 ng/mL in poorly differentiated) and the results were also highly significant (P < 0.001, χ2 test). CONCLUSION: The present work demonstrates a potential role of NGAL as cancer biomarker and its use in monitoring the HNSCC progression.

RESUMO

Squamous cell cancer is the most common type of malignancy arising from the epithelial cells of the head and neck region. Head and neck squamous cell carcinoma (HNSCC) is one of the predominant causes of cancer related casualties worldwide. Overall prognosis in this disease has improved to some extent with the advancements in therapeutic modalities but detection of primary tumor at its initial stage and prevention of relapse are the major targets to be achieved for further improvement in terms of survival rate of patients. Latest achievements in basic research regarding molecular characterization of the disease has helped in better perception of the molecular mechanisms involved in HNSCC progression and also in recognizing and targeting various molecular biomarkers associated with HNSCC. In the present article, we review the information regarding latest and potential biomarkers for the early detection of HNSCC. A detailed molecular characterization, ultimately, is likely to improve the development of new therapeutic strategies, potentially relevant to diagnosis and prognosis of head and neck cancers. The need for more accurate and timely disease prediction has generated enormous research interests in this field.

RESUMO

OBJECTIVE: Pre-eclampsia is associated with ischemia and increased oxidative stress, which may lead to modification of plasma albumin to ischemia modified albumin (IMA). METHODS: IMA levels were estimated in cord blood of 30 newborns born to pre-eclamptic mothers and compared with 30 normal newborns. IMA was estimated colorimetrically and the results were compared statistically. RESULTS: The levels of IMA were found to be significantly higher (p < 0.001) in newborns born to pre-eclamptic mothers (0.835 ± 0.02 ABSU) as compared to those born to normal mothers (0.325 ± 0.01 ABSU). CONCLUSION: IMA may act as a marker of ischemia and oxidative stress in newborns delivered to pre-eclamptic mothers.

RESUMO

BACKGROUND: Thyroid disorders especially hypothyroidism is associated with increased generation of oxidants. Nitric oxide and ischemia modified albumin are considered markers for oxidative stress. In addition, nitric oxide is involved in regulation of thyroid function and coagulation profile alteration in thyroid disorders may produce ischemia like conditions. METHODS: Nitric oxide and ischemia modified albumin were estimated in fifty patients of newly diagnosed hypothyroidism using standard photocolorimetric techniques. Results were compared with fifty healthy euthyroid controls and subjected to appropriate statistical analysis. RESULTS: Nitric oxide and ischemia modified albumin were found to be significantly raised (p < 0.05) in hypothyroid patients as compared to controls. A positive, but statistically insignificant correlation was observed between nitric oxide and ischemia modified albumin. CONCLUSIONS: Estmation of nitric oxide and ischemia modified albumin in hypothyroidism may help to throw light on its pathogenesis and assessing the severity of the disease, though further research is needed to establish their role as biomarkers in hypothyroidism.

RESUMO

Multiple animal studies, few clinical case reports and one study have observed decreased testosterone production and gynaecomastia as adverse effect of imatinib therapy. We have prospectively studied testosterone, LH and FSH levels at baseline and at 6 months of imatinib treatment in 34 newly diagnosed male BCR-ABL positive CML patients. While none of the patients had gynaecomastia at 6 months, the proportion of patients with low testosterone level increased significantly from 11.8% at baseline to 58.8% (p < 0.001) and those with high LH and FSH increased significantly from 26.4% and 23.5% to 82.4% and 76.4%, respectively (p < 0.001 and p < 0.001). Serum testosterone levels decreased significantly (p = 0.002) and serum LH and FSH levels increased significantly at 6 months of imatinib therapy (p = 0.001 and p = 0.003) in comparison to baseline levels. The findings document the effect of imatinib on testosterone levels in adult CML patients much before than reported earlier.

RESUMO

BACKGROUND: Chronic myelogenous leukemia (CML), a myeoloproliferative disorder, is characterized by the presence of the fusion gene BCR-ABL in hematopoietic cells. Leptin, considered a link between cancer and obesity, has been reported to be actively involved in hemopoiesis and pathophysiology of CML. There are few and conflicting reports about the status of serum leptin levels and recently alteration in leptin has been reported due to imatinib mesylate. METHODS: Leptin and CRP were estimated in 30 (male: 20; female: 10) newly diagnosed and confirmed MBCR- ABL p210 positive CML patients before and after 3 months of therapy by commercial enzyme linked immunosorbent assays. Leptin levels were compared with 30 (male: 20; female: 10) age matched healthy controls accounting for the differences due BMI and gender. RESULTS: Leptin/BMI ratio was significantly raised in both male and female chronic phase patients as compared to controls (p < 0.001, p = 0.048) and accelerated phase patients as compared to controls (males, p < 0.001; females, p < 0.001). The normal gender difference and dependence on BMI was lost in patients. In patients, who failed to achieve hematological baseline, leptin/BMI was higher only in male patients (p = 0.012). Leptin/BMI also correlat- ed with TLC and blast percentage (TLC, R2 = 0.412, p = 0.001; Blast %, R2 = 0.408, p < 0.001). There was no correlation between leptin and CRP levels. Levels decreased significantly after complete hematological remission in both males and females (p = 0.001, p = 0.028). Levels after 3 months of imatinib therapy were significantly higher than controls in all patients not in remission (males, p < 0.001; females, p = 0.018) but only in male patients in re- mission (p = 0.002). CONCLUSIONS: Leptin levels were increased in CML patients. The findings suggest a possible role of leptin in patho- genesis of CML or disease progression independent of inflammatory state or reactionary rise. Imatinib itself may increase leptin levels, and, as leptin plays an active role in the pathophysiology of CML, this conflicting scenario needs further investigation. Alterations in leptin need to be investigated cautiously accounting for confounding and differences due to BMI and gender.

RESUMO

OBJECTIVES: The mainstay of the treatment of head and neck squamous cell carcinoma (HNSCC) is radiotherapy, which acts by producing free radicals. Therefore, this study was planned to observe the effect of radiotherapy on oxidative stress in patients of HNSCC. METHODS: This study was conducted on 50 histopathologically proven cases of HNSCC. The levels of nitric oxide, glutathione-S-transferase, and vitamin C were estimated colorimetrically before and after treatment in patients and in 30 age- and sex-matched healthy controls. The results were compared statistically. RESULTS: The levels of nitric oxide and glutathione-S-transferase were significantly higher in patents as compared to controls and increased significantly after treatment. Vitamin C levels were significantly lower in patients as compared to controls and decreased significantly after treatment. CONCLUSIONS: HNSCC leads to increased oxidative stress and treatment in the form of radiotherapy itself produces an accentuation of this stress.

RESUMO

Nitric oxide (NO) is involved in different stages of malignancies. Increased levels of NO have been reported in different leukemias. Imatinib is the preferred drug for the treatment of chronic myeloid leukemia (CML). Turmeric powder contains curcumin which has anti-leukemic property and also decreases NO synthesis. This study was conducted on fifty patients of CML divided into two groups, group A receiving imatinib alone and group B receiving turmeric powder along with imatinib for six weeks. Nitric oxide levels were estimated in these patients before and after receiving therapy and were analyzed statistically. Nitric oxide levels were found to be significantly decreased in both the groups, but more significantly in group B after receiving the respective treatments. Thus, curcumin acts as an adjuvant to imatinib in decreasing the NO levels and may help in the treatment of CML patients.

RESUMO

BACKGROUND: Placenta accreta is a rare obstetrical condition that mainly occurs in the third trimester leading to life-threatening complications. Hereby, a case of uterine rupture due to placenta accreta occuring in the second trimester is presented. CASE PRESENTATION: A forty-year old patient who conceived after in vitro fertilization treatment (oocyte donation and embryo transfer) presented in emergency department in the nineteen weeks of gestation with acute abdominal pain, heamoperitoneum and fetal death. Emergency laprotomy showed uterine rupture along with placenta accreta for which the patient underwent subtotal hysterectomy. CONCLUSION: Although, an uncommon occurrence, physicians in assisted reproductive techniques (ART) clinics should consider placenta accreta in gravid patients who present with acute abdominal pain and shock, considering the fact that they usually have associated high risk factors for abnormal placentation.

RESUMO

BACKGROUND: Carcinomas are considered to be associated with increased cellular proliferation under antigenic stimulation and inflammation. Therefore, the markers of increased cellular turnover such as adenosine deaminase and uric acid were estimated quantitatively along with markers of inflammation such as C-reactive protein in squamous cell carcinoma of head and neck region. METHODS: The levels of adenosine deaminase, uric acid, and C-reactive protein were estimated in 50 patients of squamous cell carcinoma of head and neck region before starting any treatment and compared with their corresponding levels in 30 healthy age and gender matched controls. The patients were divided into four groups depending on their staging and their results were compared statistically and the coefficient of correlation was calculated using Pearson's formula. RESULTS: The levels of adenosine deaminase, uric acid, and C-reactive protein were found to be significantly higher in patients of head and neck cancers as compared to the levels in controls (p < 0.001). The levels were also observed to rise with staging. A positive correlation was observed between adenosine deaminase and uric acid (r = 0.743, p < 0.001), adenosine deaminase and C-reactive protein (r = 0.648, p < 0.001) and also between C-reactive protein and uric acid (r = 0.712, p < 0.001). CONCLUSIONS: Thus, estimation of adenosine deaminase, uric acid, and C-reactive protein can help in making the diagnosis and assessing the severity of disease in patients of head and neck carcinoma.

RESUMO

BACKGROUND: High levels of glycated hemoglobin (HbA(1c)) have been associated with Coronary Vascular Diseases (CVD) in diabetic patients. Recent studies have reported no association between elevated glycated hemoglobin (HbA(1c)) and incident cardiovascular disease (CVD) among women without diabetes. There are many controversial studies on topics such as "Glycated hemoglobin levels (HbA(1c)) have been associated with cardiovascular diseases (CVD) in the non-diabetic patients". Therefore, we planned this study. METHODS: The present study was conducted on 50 age matched controls and 50 clinically diagnosed non-diabetic CVD patients of either gender. The study included 50 patients with myocardial infarction (MI) admitted to the ICCU ward of J.L.N. Medical College and Hospital, Ajmer (Rajasthan). The following information was recorded from admission sheets of non-diabetic CVD patients of either gender: history of diabetes, hypertension, and cigarette smoking; demographic indices; coronary heart disease and diabetes mellitus treatment; serum cholesterol; serum triglycerides (TG); high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C); fasting and non-fasting blood glucose levels and Glycated haemoglobin levels (HbA(1c)). Glycosylated hemoglobin (HbA(1c)) was measured by latex agglutination inhibition assay. RESULTS AND CONCLUSIONS: The HbA(1c) levels in healthy controls (n = 50) and non-diabetic CVD subjects (n = 50) observed were 4.32 +/- 0.34% and 5.80 +/- 0.20%, respectively. HbA(1c) levels in these subjects were significantly higher than controls (p < 0.001). The HbA(1c) levels in non-diabetic CVD patients are higher in comparison to controls.
