Introductionand Aim: Etiopathogenesis of Pulmonary tuberculosis(PTB), is well established. Yet, the mechanisms by which a treatment regimen brings about remodelling of the pulmonary tissue during recovery phase is not well understood. The involvement of matrix metalloproteinase in this regard is debated, due to its dual role, either in disseminating the disease due to lung cavitation or reducing the inflammation due to recruitment of macrophages to the lung granulomas. PTB is a disease also driven by undernourishment.This study focuses on the association of nutritional status of PTB patients in restoring healthy lung tissue, monitored by blood levels of albumin, iron and MMP9, during the course of intensive treatment. Materials and Methods: Serum levels of MMP9, iron, Total protein and albumin were estimated in 30 PTB patients who visited the Directly Observed Treatment Short course (DOTS) Centre at Government Wenlock Hospital, Mangalore, Karnataka,India. Twenty controls were enrolled for comparative statistics. Samples were collected at baseline and after two months of DOTS treatment in case of patients.Pre-treatment and post treatment values were compared by paired t test.Student’s ‘t’ test was used for comparing parameters in controls and patients. Correlation between parameters was done by Pearson’s correlation test.   Results: A significant increase was observed in serum iron (P=0.002) and total protein(P=0.01) levels post treatment but there was no significance in the levels of MMP9. Further, serum MMP9 correlatednegatively with body weight, BMI and serum total protein levels, post treatment, which was statistically significant. No other correlations were significant. Conclusion: We conclude that MMP9 neither seems to be a diagnostic marker nor a therapeutic target in the treatment of tuberculosis. Although serum iron appears to be a predictor of improved nutritional status post treatment, it probably may have a role in tissue remodelling independent of MMP-9.

Abstract. In order to assess the possible effects of insulin on serum concentrations of trace metals (iron, copper, zinc) and trace metal binding proteins (ferritin, transferrin, coeruloplasmin), five normal females were studied with the hyperinsulinaemic-euglycaemic clamp technique. A 0.1 U/kg insulin bolus was administered, followed by an insulin infusion at a rate of 10 mU/kg/min for 12–16 h. Insulin levels of 1500–2000 μU/ml (9.21– 12.28 nmol/l) were attained. When iron levels in serum were assayed colorimetrically, there appeared to be a progressive rise in the mean concentration during the course of the insulin infusion. Direct analysis of serum samples by atomic absorption spectrophotometry also showed that the level of non-haeme iron increased 3-fold in the serum of the subject with the lowest concentration of this metal at the start of the study. In contrast with the results for serum iron, the levels of ferritin, total iron binding capacity (transferrin), zinc, copper and coeruloplasmin were not altered in any subject during the insulin infusion or at 24 h following discontinuation of the infusion. Within 4 h of institution of the hyperinsulinaemic clamp significant reductions in serum levels of potassium, phosphorus, cholesterol, total protein and albumin were noted. As the insulin infusion progressed, the urea nitrogen, uric acid and bicarbonate levels fell as well. These observations suggest that supraphysiologic hyperinsulinaemia of 12–16 h duration may alter serum levels of iron, but not serum levels of zinc, copper or trace metal binding proteins in some individuals. The mechanism(s) responsible for the rise in mean serum iron, the reductions in serum total protein and albumin, and for the development of a non-anion gap acidosis remain unclear.

Objectives: To obtain information on the nutritional maintenance effects of Ninjinyoueito (NYT) in elderly patients with chronic wasting disease, a retrospective study was conducted. Methods: we investigated changes in bodyweight and serum levels of total protein and albumin in patients who received NYT for more than 6 months for chronic wasting diseases in our hospital from April 2009 and October 2019. Results: During the study period, 11 patients (median age: 75 years) had NYT for 6 months or more. The median administration period of NYT was 14 months. The bodyweight, serum total protein, and albumin at the time of last observation were not statistically different from those at the time of the start of NYT administration (p=0.1755, p=0.7659, p=0.5498, respectively). Conclusions: Our study suggested the possibility of maintaining nutritional condition by NYT in elderly patients with chronic wasting disease of various etiologies. More evidence will be required to confirm our results. Keywords: body weight; nutritional status; ninjinyoueito; elderly patients; chronic wasting diseases

Lithium therapy, mainly used in curing some psychiatric diseases, is responsible for numerous undesirable side effects. The present study is a contribution to the understanding of the pathophysiological mechanisms underlying lithium toxicity. Male and female mature rats were divided into three batches and fed commercial pellets: one batch was the control and the second and third batches were given 2 g (Li1) and 4 g (Li2) of lithium carbonate/kg of food/day, respectively. After 7, 14, 21 and 28 days, serum levels of free tri-iodothyronine (FT3), thyroxine (FT4), testosterone and estradiol were measured. Attention was also paid to growth rate and a histological examination of testes or vaginal mucosa was carried out. In treated rats, a dose-dependent loss of appetite and a decrease in growth rate were observed, together with symptoms of polydypsia, polyuria and diarrhea. Lithium serum concentrations increased from 0.44 mM (day 7) to 1.34 mM (day 28) in Li1 rats and from 0.66 to 1.45 mM (day 14) in Li2 rats. Li2 treatment induced a high mortality after 14 days, reaching 50-60% in female and male animals. From these data, the LD50 (14 days Li2 chronic treatment) was calculated to be about 0.3 g/day per kilogram of animal, leading to Li serum concentrations of about 1.4 mM. A significant decrease of FT3 and FT4 was observed in treated rats. This effect appeared immediately for the highest dose and was more pronounced for FT3, resulting in an increase of the FT4/FT3 ratio. In males, testosterone decreased and spermatogenesis was stopped. Conversely, in females, estradiol increased in a dose-dependent manner as the animals were blocked in the diestrus phase at day 28. This finding supports a possible antagonistic effect of lithium on the estradiol receptors.

Cysteine, methionine, vitamin A, β-carotene and glutathione (GSH) are known to protect body tissues against oxidative damage and inflammation but their value as protection against liver inflammation in tropical areas has received little attention. Blood levels of these nutrients were measured in Ghanaian volunteers with (Group 2) or without (Group 1) increased lipid peroxidation and signs of liver inflammation, as indicated by blood malonic dialdehyde, serum α1-antitrypsin and triglyceride levels, and the α1-acid glycoprotein: pre-albumin ratio. Serum levels of cysteine and blood glutathione were significantly lower ( P < 0.02) in group 2 than in group 1 volunteers. In contrast, serum levels of methionine, vitamin A and β-carotene were similar in both groups. Deficits in cysteine and glutathione may increase the risk of liver toxicity from oxidants in Ghanaians.

Cyclosporin A (CsA) improves the success rate of transplantation. The CD26/dipeptidylpeptidase IV (DPP IV) system plays a critical role in mobilizing endothelial progenitor cells (EPCs) from bone marrow. This study investigated whether CsA manipulates CD26/DPP IV activity and increases EPC mobilization. C57BL/6 mice were divided into control and CsA-treated groups. Before and after hindlimb ischemia was induced, circulating EPC number and serum levels of different cytokines were measured. Compared with the controls, CsA treatment significantly increased the blood levels of stroma-derived factor-1α and stem cell factor after ischemic stress ( P < 0.001). The CsA group displayed a significant increase in the number of circulating EPCs (sca-1+KDR+ and c-kit+CD31+ EPCs, both P < 0.05). In vivo, CsA caused a significant increase in the numbers of EPCs incorporated into the Matrigel and ischemic limbs ( P < 0.05). In the peripheral blood, CsA significantly decreased CD26+ cell numbers and attenuated the plasma CD26/DPP IV activity ( P < 0.001). Furthermore, short-term CsA treatment significantly improved the perfusion of ischemic limbs and decreased the spontaneous digital amputation rate. In summary, CsA manipulates the mobilization of EPCs into the circulation via the CD26/DPP IV system. Short-term CsA treatment has beneficial effects on angiogenesis of ischemic tissues.

Background:Skeletal muscle, pulmonary and articular involvement in idiopathic inflammatory myopathies (IIM) limit the mobility/self-sufficiency of patients, and can have a negative impact on body composition.Objectives:The aim was to assess body composition and physical activity of IIM patients and healthy controls (HC) and the association with selected inflammatory cytokines/chemokines and laboratory markers of nutrition and lipid metabolism.Methods:54 patients with IIM (45 females; mean age 57.7; disease duration 5.8 years; polymyositis (PM, 22) / dermatomyositis (DM, 25) / necrotizing myopathy (IMNM, 7)) and 54 age-/sex-matched HC (45 females, mean age 57.7) without rheumatic/tumor diseases were included. PM/DM patients fulfilled Bohan/Peter criteria for PM/DM. We assessed body composition (densitometry: iDXA Lunar, bioelectric impedance: BIA2000-M), physical activity (Human Activity Profile, HAP questionnaire), serum levels of 27 cytokines/chemokines (commercial multiplex ELISA kit, Bio-Rad Laboratories) and serum levels of selected parameters of nutrition and lipidogram. Disease activity (MITAX and MYOACT activity score) and muscle involvement (manual muscle testing, MMT-8, and functional index 2, FI2) were evaluated. Data are presented as mean±SD.Results:Compared to HC, patients with IIM had a trend towards significantly increased body fat % (BF%; iDXA: 39.9±7.1 vs. 42.4±7.1 %, p=0.077), but significantly decreased lean body mass (LBM; iDXA: 45.6±8.1 vs. 40.6±7.2 kg, p=0.001; BIA: 52.6±8.8 vs. 48.7±9.0 kg, p=0.023), increased extracellular mass/body cell mass (ECM/BCM) ratio (1.06±0.15 vs. 1.44±0.42, p<0.001), reflecting deteriorated nutritional status and predisposition for physical activity, and significantly lower bone mineral density (BMD: 1.2±0.1 vs. 1.1±0.1 g/cm2, p<0.001). Disease duration negatively correlated with BMD and LBM-BIA. Disease activity (MITAX, MYOACT) positively correlated with LBM (by BIA and DXA), similarly as with basal metabolic rate (BMR), and fat free mass (FFM). CRP was positively associated with BF% (BIA and DXA). Higher BF%-DEXA was associated with worse physical endurance (FI2) and worse ability to perform physical activity (HAP). MMT-8 score negatively correlated with ECM/BCM ratio. Serum levels of several inflammatory cytokines/chemokines (specifically IL-1ra, MCP, IL-10) and markers of nutrition (specifically albumin, C3-, C4-complement, cholinesterase, amylase, insulin and C-peptide, vitamin-D, orosomucoid), and lipid metabolism (specifically triglycerides, high-density lipoprotein, apolipoprotein A and B, atherogenic index of plasma) were significantly associated with alterations of body composition in IIM patients. (p<0.05 for all correlations)Conclusion:Compared to healthy age-/sex-matched individuals we found significant negative changes in body composition of our IIM patients associated with their disease activity and duration, inflammatory status, skeletal muscle involvement, and physical activity. These data could reflect their impaired nutritional status and predispositions for physical exercise, aerobic fitness and performance.Serum levels of certain inflammatory cytokines/chemokines and markers of nutrition and lipid metabolism were associated with alterations of body composition in IIM patients. This might further support the role of systemic inflammation and nutritional status on the negative changes in body composition of IIM patients.Acknowledgments:Supported by AZV NV18-01-00161A, MHCR 023728, SVV 260373 and GAUK 312218Disclosure of Interests:Sabina Oreska: None declared, Maja Špiritović: None declared, Petr Česák: None declared, Ondrej Marecek: None declared, Hana Štorkánová: None declared, Barbora Heřmánková: None declared, Kateřina Kubinova: None declared, Martin Klein: None declared, Lucia Vernerová: None declared, Olga Růžičková: None declared, Karel Pavelka Consultant of: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Speakers bureau: Abbvie, MSD, BMS, Egis, Roche, UCB, Medac, Pfizer, Biogen, Ladislav Šenolt: None declared, Heřman Mann: None declared, Jiří Vencovský: None declared, Michal Tomčík: None declared

Objective: Many plants are consumed as food by humans for growth and survival, but a large number of these plants have not been tested for toxicity potential. Repeated consumption of such plants could lead to accumulation of toxic chemicals in the body and cause health-related problems. Irvingia wombolu kernel is widely consumed by many ethnic groups in Nigeria and some other African countries. The toxicity potentials of Irvingia wombolu kernel extract (IWKE) on the kidney and liver of rats was evaluated in this study. Methods: Three groups of Wistar rats were fed orally with IWKE (50, 100, and 200 mg/kg b.w) daily for 28 days. The fourth group which is the control was treated with distilled water (10 ml/kg b.w) for the same period.  The rats were sacrificed on the 29th day, and blood samples, kidney and liver were harvested for analyses. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, bilirubin, creatinine, and urea were determined. Kidney and liver sections were examined for histopathological changes. Data were subjected to Student’s t-test for statistical analysis. Results: Serum levels of creatinine and urea were not significantly altered in the IWKE-treated rats compared with the control. At 200 mg/kg b.w, the extract significantly increased (p<0.05) serum levels of ALT, AST, total bilirubin, total protein, and albumin compared with the control. Significant distortions were observed in the liver sections of rats treated with 200 mg/kg b.w IWKE compared with control, but the structure of the kidney section of IWKE-treated rats was not significantly different from the control. Conclusion: The results showed that repeated ingestion of Irvingia wombolu kernel at a dose of 200 mg/kg b.w for 28 days induced liver damage, but does not significantly affect renal function.                       Peer Review History: Received: 9 September 2021; Revised: 12 October; Accepted: 27 October, Available online: 15 November 2021 Academic Editor:  Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Background: The aim of this study was to estimate the serum biochemical (glucose, cholesterol, total protein, calcium, phosphorus and magnesium) and hormonal constituents (estrogen and progesterone) in female Manipuri pony mares during the different days of oestrous cycle. Methods: A total of 50 numbers of blood samples were collected from 10 numbers of apparently healthy, non-pregnant on the different days of oestrous cycle i.e. day 0, 4, 8, 14 and 18 by using commercial diagnostic kits. Result: The mean serum levels of glucose, cholesterol and phosphorus were found to be non-significant on the different days of oestrous cycle whereas the mean serum level of total protein and calcium was found significantly different (P less than 0.01). The serum magnesium level differed significantly (P less than 0.05) amongst the different days of oestrous cycle. Both estrogen and progesterone were also found to be significant (P less than 0.01) between the different days of oestrous cycle. The results showed significant influence on serum biochemical and hormonal assay during different days of oestrous cycle in female Manipuri pony.

Background Tuberculosis (TB) infection is highly prevalent in Indonesia. The source of transmission of TB to a child is usually via an adult with sputum smear-positive pulmonary tuberculosis. The Mantoux test is a diagnostic tool for tuberculosis infection. The BCG vaccine has been used for the prevention of TB, but its efficacy is still debated. Objective To assess for an association between Mantoux test results and BCG vaccination in children who had contact with adult pulmonary tuberculosis and to assess for differences in Mantoux test induration with regards to nutritional status, age, type of TB contact, and time duration since BCG vaccination in BCG-vaccinated and BCG-unvaccinated children. Methods A cross-sectional study was conducted in FebruaryMarch 2011 on infants and children (aged 3 months to five years), who had household contact with adult pulmonary TB. We performed tuberculin (Mantoux) skin tests to detect TB infection in the children. Subjects were consisted of two groups: BCG-vaccinated and BCG-unvaccinated. Results Subjects were 100 children (50 BCG-vaccinated and 50 BCG-unvaccinated subjects). Positive Mantoux test results were observed in 9 vaccinated subjects and 33 unvaccinated subjects. The mean diameters of induration in the vaccinated and unvaccinated groups were 7.6 mm and 9.6 mm, respectively (95%CI of difference -4.25 to 0.20; P=0.074). In children who had household contact with sputum smear-positive adult pulmonary TB, BCG vaccination was a protective factor against TB infection, with an odds ratio (OR) of 0.113 (95%CI 0.045 to 0.286; P=0.0001). There were no significant differences in Mantoux test induration associated with nutritional status, age, type of TB contact, and duration since BCG vaccination, between the two groups. Conclusion BCG vaccination has a protective effect on TBexposed children, based on Mantoux test results. However, there are no differences in Mantoux test induration associated with nutritional status, age, type of TB contact, or duration since BCG vaccination, between the BCG-vaccinated and BCGunvaccinated groups.
