RESUMO

The emergence of new variants of the novel coronavirus SARS-CoV-2 with increased infectivity, superior virulence, high transmissibility, and unmatched immune escape has demonstrated the adaptability and evolutionary fitness of the virus. The subject of relative order of the binding affinity of SARS-CoV-2 variants with the human ACE2 (hACE2) receptor is hotly debated and its resolution has implications for drug design and development. In this work, we have investigated the energetics of the binding of receptor binding domain (RBD) of SARS-CoV-2 variants of concern (VOCs): Beta (B.1.351), Delta (B.1.617.2), Omicron (B.1.1.529), variant of interest (VOI): Kappa (B.1.617.1), and Delta Plus (B.1.617.2.1) variant with the human ACE2 receptor by using the umbrella sampling (US) method. Our work indicates that Delta and Delta Plus variants have greater values of the US binding free energy than Wild-type (WT), whereas Beta, Kappa, and Omicron variants have lower values. Further analysis of hydrogen bonding, salt bridges, non-bonded interaction energy, and contact surface area at the RBD-hACE2 interface establish Delta as the variant with the highest binding affinity among these variants.

RESUMO

Introduction: The global burden of thyroid disorders, especially hypothyroidism, is high and increasing. Prevalence studies of such disorders are limited in Nepal. The aim of this study was to find out the prevalence of hypothyroidism among patients visiting the Department of Biochemistry in the central laboratory of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients visiting the Department of Biochemistry in the central laboratory from 1 August 2020 to 31 July 2021 after taking ethical approval from the Institutional Review Committee (Reference number: UCMS/IRC/054/20). Patients of all age groups and gender were considered. Hypothyroid patients were identified based on the thyroid function parameters. They were further categorized as sub-clinical and overt hypothyroid. A convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 3,010 patients, the prevalence of hypothyroidism was seen in 770 (25.58%) (24.02-27.14, 95% Confidence Interval). Out of total hypothyroid patients, 555 (72.08%) were females. Overt hypothyroidism 519 (67.40%) was the most prevalent hypothyroid disorder, followed by subclinical hypothyroidism 251 (32.60%). Conclusions: The prevalence of hypothyroidism among patients visiting the Department of Biochemistry in the central laboratory of a tertiary care centre was higher than in other studies done in similar settings. Keywords: hypothyroidism; Nepal; thyroid-stimulating hormone.

RESUMO

Introduction: Hypovitaminosis D is a global public health problem affecting approximately one billion people, with a particularly high prevalence in South Asia. Several hospital-based studies from Nepal show a high prevalence of hypovitaminosis D. However, large-scale community-based studies are lacking. The aim of the study was to find out the prevalence of hypovitaminosis D among blood samples of patients presenting to the Department of Biochemistry of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among blood samples of patients presenting to the Department of Biochemistry of a tertiary care centre from 3 November 2022 to 30 April 2023 after obtaining ethical approval from the Institutional Review Committee (Reference number: 136/22). Patients of all age groups and genders who were sent for the evaluation of Vitamin D at the laboratory were included. A convenience sampling technique was used. The point estimate was calculated at a 95% Confidence Interval. Results: Out of 376 patients, hypovitaminosis was seen in 274 (72.87%) (68.38-77.36, 95% Confidence Interval). Vitamin D insufficiency was present in 252 (91.97%) and vitamin D deficiency was present in 22 (8.03%) participants. Conclusions: The prevalence of hypovitaminosis D was found to be higher than other studies done in similar settings. Keywords: prevalence; vitamin D; vitamin D deficiency.

RESUMO

INTRODUCTION: Traumatic dental injury is an injury inflicted on the dentoalveolar system. It has a physical as well as a psychological impact. Despite this concern, epidemiological data regarding its prevalence is insufficient in the literature of Nepal. Hence, this study's objective was to investigate the prevalence of traumatic dental injuries for the patients visiting Universal College of Medical Sciences, Bhairahawa, Nepal, over five years. METHODS: A descriptive cross-sectional study was conducted using records from the medical record section for the patients presenting at the dental emergency outpatient department of the Universal College of Medical Sciences, Bhairahawa, Nepal, between April 2014 and April 2019. Ethical approval was taken from the Institutional Review Committee of the Universal College of Medical Sciences. Patient demographic data, type of traumatic dental injuries, and etiologies were evaluated from the record section. RESULTS: Out of 10,080 patients registered during the study period, 793 patients (7.86%) were due to traumatic dental injury, out of which 628 (79.2%) were male, and 165 (20.8%) were female. The most vulnerable age group was 20-29 years (42.4%). Most frequently, injuries occurred in June (16%). Road traffic accidents (57.8 %) were the most common mode, and complicated crown-root fracture (23.3%) was the most common type of traumatic dental injury. CONCLUSIONS: The frequency of 7.86% of traumatic dental injury indicates that dental traumatology needs special attention for policy planning and professional training.

RESUMO

BACKGROUND: Renal complications of hypertension are associated with high morbidity and mortality. Prediction of such complications at the earliest is of utmost importance. We aimed to assess the prevalence of microalbuminuria in hypertensive patients. METHODS: A total of 130 clinically diagnosed hypertensive patients were enrolled in the study. Biochemical parameters that included serum creatinine, urinary albumin, and urinary creatinine were measured using standard methods. Albumin Creatinine ratio and estimated glomerular filtration rate were calculated. Albumin Creatinine ratio values between 30-300 mg/g were considered as microalbuminuria. Statistical analysis was performed on 120 samples after excluding frank proteinuria. RESULTS: The prevalence of microalbuminuria in hypertensive patients was 19.16%. Mean ranks of systolic blood pressure, pulse pressure, and serum creatinine levels were significantly higher in hypertensive patients with microalbuminuria. Mean estimated glomerular filtration rate was significantly low in hypertensive patients with microalbuminuria. Older age and increased duration as well as severity of hypertension were not associated with a higher prevalence of microalbuminuria. CONCLUSIONS: The prevalence of microalbuminuria was high in hypertensive patients. Serum creatinine and estimated glomerular filtration rate were significantly altered in patients with microalbuminuria. Early screening of microalbuminuria in such patients might help prevent renal complications.

RESUMO

OBJECTIVES: The study was carried out with the aim to find out the frequency of Glucose 6 phosphate dehydrogenase (G6PD) deficiency among the patients attending the hospital and to rationalize the qualitative methemoglobin reduction test in reference to the quantitative spectrophotometric assay. Timely screening of the patients for G6PD with appropriate screening method can play an important role in preventing hemolytic crisis that arises from therapeutic use of oxidative drugs like primaquine. RESULT: The frequency of G6PD deficient cases was 3% by both of the employed tests. The mean ± SD of G6PD activity in the patients under study was 15.34 ± 4.7 IU/g Hb in males and 16.01 ± 3.74 IU/g Hb in females. G6PD activity was positively associated with reticulocyte count (r = 0.289, p value = 0.004) and negatively with mean corpuscular hemoglobin concentration (r = -0.220, p-value = 0.028). The correlation of red blood corpuscular count and G6PD was statistically significant (p-value = 0.048).

RESUMO

BACKGROUND: The present study compares the apical microleakage of three different root-end filling materials in which the retrograde cavity is prepared by two different burs. METHODS: Eighty extracted single rooted maxillary and mandibular premolars were taken. Root canal treatment was completed. Apical 3 mm of all the teeth were resected with diamond disk. The tooth were divided into four groups with two subgroups for each group containing 10 tooth (N = 10) as: Group IA (Negative Control and IB (Positive Control); Group IIA and IIB: Prepared with round carbide bur and round diamond bur respectively, filled with GIC; Group IIIA and IIIB: Prepared with round carbide bur and round diamond bur respectively, filled with MTA; Group IVA and IVB: Prepared with round carbide bur and round diamond bur, filled with Biodentine. After applying two coats of nail varnish leaving apical 3 mm (except for negative control group) all teeth were immersed in 2% methylene blue for 3 days and again in 65% nitric acid for next 3 days for extraction of dye. The obtained solution was then transferred to eppendorf tube and centrifuged in microcentrifuges at 14,000 revolution per minutes (RPM) for 5 min. Optical density or absorbance of the supernatant solution was measured with UV spectrophotometer at 550 nm. RESULTS: The absorbance of the supernatant solution after dye extraction is decreasing in the order of positive control> GIC > MTA > Biodentine> negative control group. The significant difference was observed between GIC and MTA (p = 0.0001) and GIC and Biodentine (p = 0.0001) with two different burs but statistically non-significant difference was observed between MTA and Biodentine with Carbide bur (p = 0.127) and Diamond bur (p = 0.496) respectively. CONCLUSIONS: Within the limitations of the present study, it can be concluded that Biodentine and MTA showed less microleakage as compared to GIC. There is no significant difference between mean microleakage of MTA and Biodentine. However, the mean OD of the Biodentine was least of all evaluated materials. Preparation of the root-end using round carbide bur as well as round diamond burs showed comparable microleakage for all three filling materials.

RESUMO

OBJECTIVES: The study was carried out to optimize the phenotypic method to characterize the sickle cell trait (SCT), sickle cell anemia (SCA), and ß-thalassemia (ß-TT) suspected sample from tharu community of South Western province-5, Nepal. SCT and SCA were further evaluated by genotypic method employing amplification refractory mutation system (ARMS PCR). Moreover, Glucose 6 phosphate dehydrogenase (G6PD) was estimated in those hemoglobinopathy to observe its prevalence. The accurate and reliable method can play an important role in reduction of morbidity and mortality rate. RESULTS: The 100 suspected cases were subjected to phenotypic method adopting cellulose acetate electrophoresis and genotypic method using ARMS PCR which portraits (5%) SCA positive test showing HBS/HBS, (38%) SCT positive trait HBA/HBS and (36%) cases normal HBA/HBA. ß-TT (21%) cases were confirmed by electropherogram. G6PD deficiency was observed in (40%) of SCA, (18.4%) of SCT, (4.8%) of ß-TT and (2.8%) in normal cases. Increased G6PD were developed only in SCT (5.3%) and ß-TT (4.8%). The study highlighted sickle cell disorder (SCD) and ß-TT as the most common hemoglobinopathy coexisting with G6PD deficiency. Though hemoglobinopathy sometime could be protective in malaria but G6PD deficiency can cause massive hemolysis which may exacerbate the condition.

RESUMO

BACKGROUND: Road traffic injuries (RTIs) are a complex phenomenon caused by nonlinear combination and interaction of man, vehicles, road, and environment. AIM: This study aims to find out the outcome and severity of RTI in a district of West Bengal, India. SETTINGS AND DESIGN: A cross-sectional study was conducted among inpatients of Departments of Surgery and Orthopedics of Bankura Sammilani Medical College and Hospital, West Bengal, India. MATERIALS AND METHODS: The study was conducted for 1 year interviewing 295 RTI selected through scheduled sampling. Information pertaining to demographic and correlates of RTI was collected by face to face and over telephone using semi-structured questionnaire. Nine-item Simplified Injury Severity Scale (SISS) was used to assess injury severity. Internal consistency of SISS scale was showed by Cronbach's alpha and association with the correlates was done by Mann-Whitney U-test. STATISTICAL ANALYSIS USED: With SPSS version 22.0, binary logistic regression, and Mann-Whitney U-test. RESULTS AND CONCLUSION: Fatal outcome in terms of death and permanent disability was 34.24% and they had higher marginally significant (P = 0.06), SISS score (45.17 ± 12.59). Participants with absence of protective devices, presence of comorbidities, drunkenness, with accidents over national highways, in-between 6 am and 6 pm, mechanized two-wheelers, and nonreceipt of first aid were found to have significantly high scores compared to their counterpart. SISS, as a proxy measure of severity assessment, could throw a light on it and awareness generation and legislative stringency might be need of the hour for the country.

RESUMO

BACKGROUND: Perceived stress and burnout are by-products of powerless responsibility imposed on resident doctors. Emotional intelligence (EI) works as an adapting and coping tool. OBJECTIVE: The objective of this study is to find out the role of work-related perceived stress on burnout and influence of EI on it. METHODS:: A descriptive cross-sectional study was conducted from February to April 2016 among 63 resident doctors of different departments of Bankura Sammilani Medical College and Hospital. Data were collected through a self-administered questionnaire for background characteristics and work-related variables. Cohen perceived stress scale, Trait EI, and Shirom-Melamed burnout questionnaire were applied for measuring perceived stress, EI, and burnout, respectively. Statistical analysis was done with of SPSS version 22.0, and for mediation analysis, Andrew F. Hyne's SPSS macro was adopted. Nonparametric bootstrapping was done assuming small sample. RESULTS: Out of complete responses, 67%, 22.9%, and 9.8% were from clinical, paraclinical, and preclinical specialties, respectively. Burnout had a significant positive correlation with perceived stress and in negative correlation with EI-well-being and positive correlation with EI-self-control and sociability. Physical fatigue factor of burnout had a significant positive correlation with EI-emotionality. Perceived stress had a negative correlation with EI-well-being. On mediation analysis, assuming EI as a mediator, total, direct, and indirect effects of perceived stress on burnout were significant (<0.05). Mediation was proved to act with percent mediation of 0.07. CONCLUSION: There was definite mitigating effect of EI on burnout by perceived stress among resident doctors. This necessitates more attention by decision-makers toward this burning problem for the sake of care of caregivers.

RESUMO

BACKGROUND: Early childhood education (ECE) is an important service provided by Integrated Child Development Services (ICDS). It is largely responsible for developing school readiness in children. OBJECTIVE: The objective of this study is to assess ECE component of ICDS services through measurement of school readiness and find out other correlates. METHODS: A cross-sectional evaluation study was carried out among Anganwadi centers (AWCs) under Bankura Municipality, West Bengal, India from July to November 2015. AWCs were selected by 30 cluster sampling. From each selected center Anganwadi worker (AWW), 7 randomly selected children of 5 years of age and their caregivers were included in the study. Data were collected by assessment of children, interview of AWWs and caregivers of children, observation of ECE activity and record review using ECE Program Evaluation Package developed by World Bank and predesigned schedule. Mean, standard deviation, proportions were estimated for description and correlation, unpaired t-test, analysis of one-way variance, multivariable linear regression were performed to find out correlates of school readiness using SPSS 22.0 version. RESULTS: Average duration of ECE activity was 66.0 min/day which was far less than the norm. Overall average score of school readiness of 210 children was 14.0 out of 40. Inadequate physical facility, poor classroom performance acted as deterrents for school readiness. Help in the study at home was revealed to be a determinant of school readiness. CONCLUSION: For the preparation of formal schooling of children most important needs of the hour are physical facility of AWCs, supportive supervision of AWWs, and creation of congenial environment at home.

RESUMO

BACKGROUND: Diabetic retinopathy (DR) is one of the leading causes of preventable blindness in low and middle income countries. In Nepal, there are less studies regarding DR and they too are limited around Kathmandu valley. This study was done to assess visual morbidity in patients with DR at a peripheral tertiary eye care center of Nepal. METHODS: This was a prospective, hospital based, cross-sectional study in which all consecutive cases of DR were evaluated. DR was classified according to Early Treatment Diabetic Retinopathy Study Research Group - report no. 10 Table A5-1 (Modified Airlie House Classification). Data entry and analysis was done in an SPSS unit version 20. Wherever applicable, variables were set as 100 eyes. RESULTS: Total number of patients included in this study was 50. Commonest age group was 50-69 yrs. (43/77 yrs.; min/max) comprising 80% of the total population (n = 50) and the predominant population was male (76%). Non proliferative diabetic retinopathy (NPDR) was found in 69%, proliferative diabetic retinopathy (PDR) in 31% and advanced diabetic eye disease (ADED) in 3% (n = 100). CONCLUSIONS: All the stages of DR were present at significant proportions in this study, noteworthy was the percentage of PDR. This study shows an urgency to gather a national data on DR, raise awareness among diabetics and train effective man power at a local level to diagnose DR at an early stage.

RESUMO

OBJECTIVES: The objective of the study was to assess the differences of iodine status as measured by urinary iodine excretion (UIE) between cases of hypothyroidism and healthy controls. MATERIALS AND METHODS: The study was conducted in cases with subclinical hypothyroidism (n = 58) and overt hypothyroidism (n = 41) and compared with age- and sex-matched healthy euthyroid controls (n = 52) attending Universal College of Medical Sciences Teaching Hospital, Bhairahawa, Nepal. Serum free triiodothyronine (fT3), free thyroxine (fT4), and thyroid-stimulating hormone (TSH) were estimated by competitive ELISA and sandwich ELISA, respectively (Diametra, Italy). The urinary iodine concentration (UIC) in urine samples was estimated by ammonium persulfate digestion method recommended by the WHO. RESULTS: A significantly higher median UIC was observed among cases of subclinical hypothyroidism (224.90 µg/l) and overt hypothyroidism (281.0 µg/l) as compared to the controls (189.90 µg/l) (P = 0.0001, P = 0.001). Serum TSH in the cases of subclinical hypothyroid was higher, whereas fT3 was lower as compared to controls (P = 0.028, P = 0.0001), respectively. Similarly, serum TSH in the cases of overt hypothyroid was higher and fT3 and fT4 were lower as compared to controls (P = 0.0001, P = 0.0001, P = 0.015), respectively. There was positive correlation of UIC with TSH (r = 0.269, P = 0.0001), whereas negative correlation was seen with fT3 (r = -0.328, P = 0.0001) and fT4 (r = -0.145, P = 0.076). The test of multiple regression has shown that fT3 (ß = -0.262, P = 0.012) as an independent predictor in association with UIE in cases. CONCLUSION: Excessive iodine intake was found in hypothyroid patients as assessed by UIE concluding that it may trigger the thyroid hypofunction. Cohort studies to generate further evidence should be done to explore potential mechanism of hypothyroidism in excess iodine intake.

RESUMO

PURPOSE: Gallstone is a high-risk factor for gallbladder pre-malignancy or malignancy (GB PM-M) but which substances of gallstones definitely assist to turn out in to GB PM-M, remains unclear. This study aimed to find out the presence of carcinogenic heavy metals in gallstones and to explore the aetiopathogenesis of gallbladder pre-malignancy and malignancy. METHODS: Presence of elements in gallstones was detected by energy dispersive X-ray spectroscopy (EDS) with scanning electron microscopy (SEM) and then level of carcinogenic heavy metals was estimated in gallstones using atomic absorption spectroscopy (AAS). The experiment was carried out in gallstone samples of 46 patients with gallbladder pre-malignant and malignant condition (PM-M group) and 65 sex and age-matched patients with chronic cholecystitis (C-C group). Gallstones were also classified in to three types such as cholesterol stone, mixed stone, and black pigment stone. RESULTS: EDS analysis detected presence of mercury, lead, and cobalt elements in all types of gallstones of both PM-M and C-C groups. AAS analysis revealed significantly higher amount of mercury (p < 0.001), lead (p < 0.0001), cobalt (p < 0.01), and cadmium (p < 0.01) in the gallstones of PM-M than C-C groups. The presence of these heavy metals also varied among stone types of both groups. EDS phase analysis showed 'dense deposits' of these metals in gallstones. CONCLUSIONS: Presence of significantly higher amount of mercury, lead, cobalt, and cadmium in gallstones may play a pivotal role as risk factors in the development of gallbladder malignancy or pre-malignancy. 'Dense deposits' of these metals in the gallstones which is the first observation, may act as crucial doses of carcinogens.

RESUMO

BACKGROUND: Amenorrhea is the absence of menstrual periods. It has multiple social consequences as it may leads to infertility. This case control study was conducted for determining the association of thyroid hormones with hyperprolactinemia in patient with amenorrhea. METHODS: We investigated 50 women with diagnosed cases of secondary amenorrhoea, who attended UCMS hospital, for hormonal evaluations. Fifty two healthy women were taken as the controls. The thyroid dysfunction and serum prolactin level were reviewed in cases and in the controls. RESULTS: Mean serum prolactin level was found to be significantly higher in the cases as compared to the controls. Mean serum fT3 and fT4 level in the hyperprolactinemic cases (mean = 2.67, SD = 1.04 pg/ml) and (mean = 1.38, SD = 0.51 ng/dl respectively) were slightly lower as compared to normoprolactinemic cases (mean = 3.21, SD = 1.86 pg/ml) and (mean = 1.73, SD = 1.37 ng/dl) respectively. Mean TSH of normoprolactinemic and hyperprolactinemic cases were comparable (P = 0.049). There was positive correlation between prolactin, BMI and TSH whereas negative correlation of prolactin was seen with fT3, fT4 and age. In hyperprolactainemic cases, prolactin was found to be negatively correlated with TSH (r = -0.155, P = 0.491) whereas prolactin was positively correlated with TSH (r = 0.296, P = 0.126) in normoprolactainemic cases. CONCLUSIONS: Thus, hyperprolactinemia with thyroid dysfunction may be contributory hormonal factor in patient with amenorrhoea and as such, estimation of prolactin, fT3, fT4 and TSH should be included for diagnostic evaluation of amenorrhea.

RESUMO

BACKGROUND: Diabetes mellitus (DM) is a chronic disease characterized by insulin deficiency or peripheral resistance resulting in hyperglycemia. Poor glycemic control leads to diabetic complications. Hyperuricemia has been reported with increased risk of renal insufficiency. The aim of this study was to evaluate the relationship between serum uric acid concentration, degree of urinary albumin excretion (UAE) and glycated hemoglobin (HbA1c) in Type 2 DM (T2DM) patients. MATERIALS AND METHODS: Serum uric acid concentrations, urine microalbumin, and HbA1c were measured in fifty T2DM patients. We then evaluated relationship between uric acid concentrations, degree of UAE and glycemic control as well as other confounding variables. RESULTS: Serum uric acid concentration correlated positively with UAE (r = 0.323, P < 0.05), age (r = 0.337, P < 0.05), age at onset (r = 0.341, P < 0.05), and duration of DM (r = 0.312, P < 0.05). Multiple regression analysis demonstrated that serum uric acid concentration (ß = 0.293, P < 0.0001), duration of DM (ß = 0.261, P < 0.0001), HbA1c (ß = 0.173, P < 0.005), and systolic blood pressure (ß = 0.268, P < 0.005) were independent determinants of UAE. CONCLUSIONS: Serum uric acid concentration is associated with microalbuminuria and HbA1c in T2DM patients.

RESUMO

BACKGROUND: Bancroftian filariasis is the second most common mosquito-borne disease in India. Government of India adopted mass-drug-administration (MDA) since 2004 for its elimination by 2015 AD. OBJECTIVE: The aim was to assess the coverage, compliance, factors-related to noncompliance to MDA. MATERIALS AND METHODS: A cross-sectional survey of 1 week was conducted within 2 weeks after completion of MDA for 2012 in three villages and two municipal wards of North 24 Parganas district of West Bengal, India selected as clusters by multistage random sampling. Information was collected via interview of inhabitants of the clusters selected by systematic random sampling and drug administrators of the selected clusters along with verifying left over medicines, if any. RESULTS: Both appropriate medicine distribution (83.4%) and 61.28% of people who received drug reported consumption and effective consumption rate (48.01%) fell short of the target. The lowest consumption (38.15%) was noted in one of the rural cluster (villages), followed by municipal wards (43.14%). Consumption was significantly higher among rural residents and Hindu community. Fear of the adverse reaction was the commonest (63.02%) cause of noncompliance. Contrary to the requirement, almost all consumptions were unsupervised by drug administrators. Only 10.71% of the respondents reportedly were paid house to house campaign of forthcoming MDA. About 64% participants had heard about filariasis out of which 71% & 47% mentioned swelling of legs as symptoms and mosquito bite as mode of spread, respectively. About one-third opined mosquito control and MDA each as means of prevention. Approximately, 60% participants had heard about MDA. Information education and communication related to MDA program was conspicuously inadequate in the last round. CONCLUSION: Mass mobilization as in intensive pulse polio immunization with effective monitoring and supervision is the need of the hour for universal coverage of MDA with supervised on the spot consumption of tablets.

RESUMO

A tertiary level hospital-based case control study on frequency of changing presbyopic glasses among primary open angle glaucoma cases was carried out jointly by the departments of community medicine and ophthalmology from 1st July to 31st December, 2008. Each of the case and control groups included 31 persons. Odd's ratio of 4.55 (95% CI = 1.37-15.68) using epi-info version 3.2 showed that among primary open angle glaucoma cases the time of changing spectacles at < or = 2 years was 4.55 times more than that among control group; Pearson's Chi-square test (chi2 = 7.94, df = 1, p = 0.00) was statistically significant; Z-test for proportion = 2.56, p=0.01. So changing spectacles at < or = 2 years among patients would help the paramedical workers/paramedical ophthalmic assistants in the community to refer the patients earlier to ophthalmologists for further investigation and management.

RESUMO

This case-control study followed by a longitudinal cohort study was undertaken to evaluate the level of lipid peroxidation product malondialdehyde (MDA) and nitrite as an indirect measurement of nitric oxide vis-à-vis the levels of antioxidants vitamin C and vitamin E in pulmonary tuberculosis. Fifty-six sputum smear-positive cases of pulmonary tuberculosis based on Ziehl-Neelsen (ZN) staining and 50 healthy controls without any systemic disease were included in this study. Thirty-five cases were longitudinally followed up with standard antituberculosis chemotherapy (ATT) for two months. Serum levels of malondiadehyde (MDA), nitrite, and plasma levels of vitamins C and E were measured. The mean serum MDA level was significantly higher (8.1 +/- 1.61 nmoles/ml) in PTB patients before commencement of ATT as compared to healthy controls (3.45 +/- 1.7 nmoles/ml) (p=0.0001) and decreased significantly after 2 months of ATT (3.84 +/- 1.28 nmoles/ml) (p=0.0001). The mean serum nitrite level (47.19 +/- 18.44 micromol/l) was significantly elevated before ATT compared to healthy controls (32.89 +/- 11.94 micromoles/l) and decreased significantly after 2 months of ATT (27.71 +/- 11.97 micromoles/l) (p=0.0001). The mean plasma levels of vitamins C (0.88 +/- 0.33 mg/dl) and E (0.79 +/- 0.24 mg/dl) in PTB patients before commencement of ATT were lower than healthy controls (1.42 +/- 0.38 mg/dl) and (1.35 +/- 0.35 mg/dl), respectively (p=0.001). There was a significant increase in vitamin C levels after 2 months of ATT (1.19 +/- 0.40 mg/dl) compared to before ATT (0.83 +/- 0.31 mg/dl) (p=0.0001), but no significant change in mean plasma vitamin E level before and after 2 months on ATT was found. Elevated malondialdehyde and nitrite levels with concomitant depressed vitamin C and E levels are indicative of lipid peroxidation and oxidative stress. The decrease in levels of malondialdehyde and nitrite with subsequent increase in vitamin C levels after two months of follow-up indicate a good response to treatment with standard ATT. Hence, the extent of oxidative stress in PTB can be evaluated by analyzing lipid peroxidation product, antioxidant and nitric oxide levels.

RESUMO

Cerebrospinal fluid (CSF) adenosine deaminase (ADA) activity in tubercular meningitis (TBM) patients (n=20), non-tubercular meningitis (NTBM) patients (n=10) and non-tubercular non-meningitis (NTBNM) cases (n=15) were measured by the method based on Berthlot's reaction. The mean CSF ADA activity in TBM (13.62 +/- 8.45 IU/L) was found to be significantly higher as compared to NTBM (6.51 +/- 2.41 IU/ L, p<0.001) and NTBNM (2.35 +/- 1.16 IU/L, p<0.0001) respectively. The sensitivity and specificity of CSF ADA activity was 85.0% and 88.0% respectively at cut-off value of 6.97 IU/L to diagnose tubercular meningitis. The specificity and sensitivity of CSF ADA for TBM was found to be 85.0% and 70.0% as compared to NTBM and 85.0% and 100.0% as compared to NTBNM. We propose that estimation of that ADA activity in CSF of TBM patients, using a cut off value 6.97 IU/L can diagnose differentially tubercular meningitis. Since, most developing countries have the dubious distinction of having higher prevalence and incidence of tubeculosis and lack of well equipped laboratory services for proper diagnosis of tubercular meningitis, measurement of CSF ADA activity can be a better and reliable approach for the rapid diagnosis and management of tubercular meningitis vis a vis other types of meningitis.
