Objectives:To assess the diagnostic role of CSF C-reactive protein quantitatively in acute meningitisand to evaluate the efficacy of CSF C-reactive protein in differentiating pyogenic meningitis fromnon-pyogenic meningitis.Material and Methods: It is a prospective observational study of total 102children with suspected meningitis allocated into three groups based on initial investigations; group-I Pyogenic meningitis, group-II Non-Pyogenic meningitis and group-III No meningitis (Controlgroup). Quantitative CSF C-reactive protein was detected by the latex agglutination method. Datawere analyzed to establish the diagnostic role of CSF-CRP and to evaluate the efficacy of CSF-CRP indifferentiating pyogenic meningitis from non-pyogenic meningitis.Results: A total of 102 clinicallysuspected meningitis patients were studied. Based on CSF findings, the study population (102cases) was categorized into 3 groups. Group I was pyogenic meningitis consist 53 cases (51.96%).Group II was Non-Pyogenic meningitis consists 27 cases (26.47%). Group III was normal CSFfindings consist 22 (21.56%). 98.1% cases of pyogenic meningitis had elevated CSF-CRP level >1.1μg/ml of CSF. In the case of Non-Pyogenic meningitis, 96.2% were found to have CSF- CRP in therange of 0.05-0.10 μg/ml. The mean value of CSF-CRP in groups I,II and III were 5.57±1.48,0.09±0.042 and 0.01±0.010 respectively. Conclusion: Detection of CSF-CRP provides a newdimension to establish the diagnosis of pyogenic meningitis. It is a rapid, reliable and sensitivediagnostic test. From this study it is concluded that CSF-CRP can be used to differentiate pyogenicfrom non-pyogenic meningitis. Early, accurate and appropriate therapy can ameliorate the morbidityand mortality rates in such cases.

The forearm perfusion technique was used 1) to quantify the muscle metabolism of glucose and gluconeogenic precursors in response to insulin-induced hypoglycemia and 2) to assess the role of catecholamines and glucose concentration, pe se. Insulin (0.5 mU.kg-1.min-1) was infused for 4 h in three groups of healthy volunteers. In group I (n = 6), blood glucose (BG) was maintained at its basal level (4.5 +/- 0.1 mmol/l). In group II (n = 7), BG was allowed to fall to approximately 3 mmol/l. Group III (n = 6) was similar to group II except that propranolol was infused also. In addition, at 240 min, hypoglycemia was locally corrected by intrabrachial glucose infusion while maintaining the systemic milieu unperturbed. In group I, forearm glucose uptake (FGU) increased from 4.7 +/- 1.3 to a mean value of 37.8 +/- 5.0 mumol.l-1.min-1, whereas in group II it remained unchanged (8.3 +/- 2.0 mumol.l-1.min-1). In group III, propranolol partially prevented the suppression of FGU that increased to 21.6 +/- 5.2 mumol.l-1.min-1 (P < 0.05 vs. group II). Local correction of hypoglycemia normalized the FGU response (36.5 +/- 8.0 mumol.l-1.min-1). Muscle release of lactate, but not of alanine, was slightly higher during hypoglycemia (P = not significant). Forearm blood flow remained unchanged in groups I and III, whereas it increased by approximately 40% in group II (P < 0.05). It is concluded that, during mild hypoglycemia 1) extreme insulin resistance develops in the skeletal muscle, mediated by beta-adrenergic stimulation and reduced glucose mass effect and 2) mobilization of gluconeogenic precursors is only weakly activated.

Objectives: The aim was to evaluate and compare pretreatment serum C-reactive protein (CRP) levels in patients with oral premalignancies and malignancies with that in healthy controls. Materials and Methods: The study sample consisted of 90 patients of both genders. The subjects were divided into three groups. Group I comprised 30 healthy controls, while group II included 30 patients with potential oral malignancies including leukoplakia, oral submucous fibrosis (OSMF), and oral lichen planus (OLP), and group III included 30 squamous cell carcinoma (SCC) patients confirmed by histopathological examination. All samples were subjected to CRP analysis. Serum CRP levels were quantitatively determined using the automated immunoturbidimetric method. Results: In group I, CRP levels were ranging from 0.1 to 18.3 mg/l with the mean ± standard deviation (SD) CRP level of 3.88±4.50 mg/l. In group II, CRP levels were ranging from 0.8 to 53.9 mg/l with the mean ± SD CRP level of 5.59±9.86 mg/l. In group III, CRP levels were ranging from 3.3 to 96 mg/l with the mean ± SD CRP level of 31.72±31.01 mg/l. Conclusions: According to the results, prediagnostic concentrations of CRP are associated with subsequent development of oral cancer and suggest that plasma CRP level is a potential marker of increased risk of cancer

In this study, genotoxic effects of repeated sevoflurane anaesthesia were investigated in rabbits with or without antioxidant supplementation. Twenty-one New Zealand male rabbits were included in the study and randomized into three groups as: placebo treated (Group I), vitamin E supplemented (Group II) and selenium supplemented (Group III). Vitamin E and selenium were given intraperitoneally for 15 days before anaesthesia treatment. Anaesthesia was administered using 3% sevoflurane in 4 L/min oxygen for a 3-hour period and continued for 3 days. Blood samples were collected before anaesthesia (Sample 1), after the first, second and third days of sevoflurane administration (Sample 2, Sample 3 and Sample 4 respectively) and the last samples were taken 5 days after the last sevoflurane administration (Sample 5). Genotoxic damage was examined using the comet assay. The degree of damage is assessed by grading the cells into three categories of no migration (NM), low migration (LM) and high migration (HM) depending on the fraction of DNA pulled out into the tail under the influence of the electric field. The number of comets in each sample was calculated (1 × number of comets in category NM + 2 × number of comets in category LM + 3 ×number of comets in category HM) and expressed as the total comet score (TCS), which summarizes the damage frequencies. In Group I, a significant increase in the mean TCSs was observed for Samples 3 and 4 as compared with Sample 1. However, there were no significant differences between Samples 1, 2 and 5. The mean TCS of Sample 4 was significantly higher than Sample 1, 2 and 3 in Group II. Group III demonstrated no significant mean TCSs for any experimental conditions. Statistical differences were also observed between the groups with significant P values. This experimental study points out the presence of DNA damage with repeated sevoflurane anaesthesia and the genoprotective role of antioxidant supplementation on DNA damage in mononuclear leukocytes of rabbits by highly sensitive comet assay.

We have determined the sites of action of endothelin-1 (ET) in the lamb pulmonary circulation. The influence of cyclooxygenase inhibition and baseline vasomotor tone on ET effects was also studied. Lungs of 14 lambs (6-9 wk of age, 12.1 +/- 0.6 kg body wt) were isolated and perfused with blood. Group I lungs (n = 5) were untreated, group II lungs (n = 5) were treated with indomethacin to inhibit cyclooxygenase, and group III lungs (n = 4) were treated with indomethacin and a thromboxane A2 analogue, U-46619, to elevate vasomotor tone. All lungs were perfused with constant flow in zone 3, with left atrial and airway pressures being 8 and 6 cmH2O, respectively. We measured pulmonary arterial pressure and, by the micropuncture servo-null method, pressures in 20- to 50-microns diameter subpleural venules, both before and after each dose of ET was infused (50, 100, 250, and 500 ng/kg). Group I lungs, with high baseline vasomotor tone, exhibited a biphasic response to ET; 50-100 ng/kg of ET dilated both arteries and veins, whereas 500 ng/kg of ET constricted both arteries and veins. In group II lungs with low vasomotor tone, all doses of ET caused constriction of arteries only. In group III lungs (indomethacin treated with elevated vasomotor tone), 50-100 ng/kg of ET caused dilation of arteries and veins, whereas 500 ng/kg of ET induced constriction, this time only in arteries. We conclude that ET has both dilator and constrictor effects in arteries and veins of isolated, perfused lamb lungs. ET-induced arterial and venous dilation is dependent on initial vasomotor tone but not on cyclooxygenase metabolites.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract Background. Approximately 5% of COVID-19 patients suffer near fatal disease. Clinical and radiologic features may predict severe disease albeit with limited specificity and radiation hazard. Laboratory biomarkers are eyed as simple, specific and point of care triage tools to optimize management decisions.This study aimed to study the role of inflammatory markers in prognosticating COVID-19 patients.Methodology. A hospital based retrospective study was conducted on COVID-19 adult inpatients classified into three groups as mild disease-recovered [Group I], severe disease-recovered [Group II] and dead [Group III]. Categorical outcomes were compared using Chi square test. Univariate binary logistic regression analysis was performed to test the association between the explanatory and outcome variables. Unadjusted OR along with 95% CI was calculated. The utility of lab parameters (Ferritin, LDH, D dimer, N/L ratio and PLT/L ratio) in predicting severity of COVID-19 was assessed by Receiver Operative Curve (ROC) analysis. P value < 0.05 was considered statistically significant.Results. The mean age was 49.32 +/- 17.1 years. Among study population, 378 were Group I, 66 Group II, and 56 Group III. Median levels of Ferritin among the 3 groups were 62ng/mL, 388.50 ng/mL and 1199.50 ng/mL. Median value of LDH were 95U/L, 720 and 982.50(p <0.001). D-dimer values of 3 groups were 23.20ng/mL, 104.30 ng/mL and 197.10 ng/mL (p <0.001). CRP done qualitatively was positive in 2 (0.53%), 30 (45.45%) and 53 (94.64%) of patients. The odds of patients suffering severe COVID-19 rose with rising values of ferritin, LDH and D-dimer [unadjusted OR 1.007, 1.004 &1.020]Conclusion. One time measurement of serum ferritin, LDH, D-dimer and CRP is promising to predict outcomes for COVID 19 inpatients. Single qualitative CRP was equally good but more cost effective than quantitative CRP. The most specific combination was NLR, Lymphocyte percentage and D-dimer levels done between 7th – 10th day of symptoms.

Saving Effect

The beneficial effect of low pH during cardiac ischemia on reperfusion injury has often been attributed to its energy-saving effect due to inhibition of contraction. The role of low pH on Ca2+ accumulation and muscle tension was assessed in energy-depleted tissue by changing the pH of the medium from 7.4 to 6.2 at onset of rigor development during metabolic inhibition (MI), i.e., in the energy-depleted phase. Cytosolic free Ca2+ ([Ca2+]i) and intracellular H+ (pHi) were measured in rat trabeculae at 20 degrees C with fura 2 and 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein, respectively, and tension was recorded. The preparations were energy depleted by stimulation at 1 Hz in glucose-free Tyrode solution with 2 mM NaCN. Rigor developed within 20 min, indicating energy depletion. Resting [Ca2+]i was followed during 50 min (group I) or 100 min (group II) of rigor, and recovery was followed for 60 min in glucose-containing Tyrode solution at 0.2-Hz stimulation. Resting [Ca2+]i rose within 50 min (group I) but stabilized in the 50- to 100-min period (group II). All preparations from group I (n = 5) resumed contraction in the recovery period but in group II (n = 10) 70% failed to recover, and [Ca2+]i remained elevated compared with those that recovered. An extracellular pH of 6.2, resulting in similar pHi, from onset of rigor development (group III) led to only a modest rise in [Ca2+]i during the 100-min rigor period, and all preparations resumed contraction after approximately 3 min in normal medium. ATP was very low in all groups at the end of MI but was still significantly lower in group II than in groups I and III. A beneficial energy-sparing effect of low pH during the rigor phase can therefore not be excluded. We conclude that 1) the capacity of trabeculae to recover from MI depends on the time period and magnitude of the [Ca2+]i rise in the energy-depleted phase and 2) low pH in energy-depleted trabeculae protects against Ca overload, improving recovery after normalization of perfusion conditions.

Insufficiency Syndrome

Introduction. Mortality in generalized peritonitis (GP) reaches 30%, and with the development of multiple organ failure, the lethal outcome is observed in 80-90% of cases. Enteral insufficiency syndrome (EIS) plays a leading role in the progression of generalized peritonitis. The aim of the study was to develop a differentiated approach of enteral insufficiency syndrome correction in patients with generalized peritonitis. Material and methods. This research was a retrospective prospective study. The study included 50 patients with GP, who received treatment at the Surgery Department of the Samara Regional Clinical Hospital in the period from 2017 to 2019. Depending on the chosen treatment tactics, the patients were divided into two clinical groups. Group I included 29 patients, admitted in the period from 2017 to 2018, who had received the standard GP treatment. A long-term endogenous intoxication in patients of this group associated with the progressive enteric failure led to the repeated surgeries; at the same time, a high frequency of postoperative complications was preserved. The analysis of the results in patients of Group I necessitated development of the therapeutic and diagnostic algorithm aimed at early diagnostics and timely correction of EIS. Group II included 21 patients with GP, admitted in the period from 2018 to 2019, who was treated using the new algorithm. Results. The objective criteria for the relief of EIS in GP in patients of the study groups were a decrease in the level of serum albumin and C-reactive protein, a significant decrease in the amount and qualitative change in the intestinal discharge via an intestinal tube, a decrease in the recovery time of the functions of the small intestine and start of defecation. On the 6th postoperative day, in patients of Group II there was no significant albumin level reduction in comparison with the 1st day of monitoring (28.310.77 g/l vs 37.334.69 g/l). Whereas in Group I the albumin level was significantly lower (19.30.51 g/l) than the same parameter in Group II, and in comparison with the 1st day of monitoring (19.30.51 g/l vs 39.56.05 g/l; р = 0.00001). On the 6th postoperative day, the C-reactive protein level differed significantly between the groups as well: Group I 104.7613.49 mg/l, Group II - 58.0029.05 mg/l, p = 0.003. The control of GP in patients of the Group I was reached after 4.52.5 repeated abdominal interventions, while in patients of Group II generalized peritonitis was arrested after 2.30.9 surgical interventions (p = 0.000171), which is 1.9 times less. Conclusions. The proposed algorithm of EIS control is based on the individual approach to the treatment of patients with GP. The developed EIS rating scale allows determining not only the degree and dynamics of the pathological process, but also monitoring the effectiveness of treatment options applied in a particular patient.

Background:To accurately stratify patients undergoing PCI, according to their risk of future adverse events, a quest for risk predictors is ongoing worldwide. But only a few powerful and independent predictors of early and late major adverse cardiovascular events have been found. These include traditional risk factors, such as acute coronary instability, diabetes mellitus, reference vessel diameter, and lesion and/or stent length. This study was undertaken to find out the relationship between pre-procedural CRP level with in-hospital (both procedural and before discharge) complications. Materials & methods: This prospective study was carried out in National Institute of Cardiovascular Diseases (NICVD), Dhaka during the period of June,2006 to May,2007. After fulfilling the exclusion criteria, 100 consecutive patients were selected as sample those underwent percutaneous coronary intervention. C-Reactive protein (CRP) was measured in all patients before the procedure. Those having pre-procedural CRP level <.3 mg/dl was labeled as group-I and those with CRP level e”.3 mg/dl was labeled as group-II. In hospital outcomes were compared between two groups after percutaneous coronary intervention. Results: During the procedure, higher rate of complications (10.0% vs 26.0%) were noted in group- II, which was statistically significant. Among many complications abrupt occlusion, threatened (dissection and new thrombus) and residual stenosis were significantly high in group-II. Other complications like coronary spasm, arrhythmia, side branch occlusion, heart failure, shock and no reflow were also high in higher level of CRP level patients but statistically not significant. Inhospital complications were also significantly high (10.0% vs 28.0%) in patients with higher level of CRP ie. Group-II. Among other complications recurrence of ischemia and myocardial infarction developed at significantly higher rate in group-II. Post procedural CK-MB rose significantly (18.0% vs 36.0%) in patients with higher level of CRP (group-II) in comparison to normal level of CRP patients (group-I). When the in-hospital complications were distributed among three tertiles of CRP, it was observed that complications were proportionately high with increasing level of CRP. Conclusions: Many studies, conducted abroad, have suggested that factors like gender, extreme age, diabetes, multi-vessel disease and lesion characteristics adversely influence PCI outcome. But in this study, multivariate regression analysis has shown that elevated level of CRP is even stronger independent predictor of PCI outcome. Keywords: C-Reactive Protein; In hosital outcome; PCI.
