Longitudinal changes in bone mineral density may be associated with long-term survival in patients with cirrhosis: A proof of concept of study.

INTRODUCTION: The impact of longitudinal changes in different body components measured via body composition analysis (BCA) on liver-related outcomes in patients with cirrhosis is poorly understood. We evaluated the prognostic relevance of longitudinal changes in body composition over one year in patients with cirrhosis. METHODS: This was a follow-up study of a randomized controlled trial evaluating changes in bone density measured via dual energy X-ray absorptiometry (DEXA) upon vitamin D supplementation. Patients with available anthropometric indices, fat mass (FM), fat-free mass (FFM), bone-density at lumbar spine (LD) and left femur-neck (FD) (assessed by T score) at two time points one year apart were assessed for outcomes. The prognostic relevance of change in parameters such as ΔFM, ΔFFM, ΔLD and ΔFD over one year was assessed and compared with baseline model for end-stage liver disease (MELD) score. RESULTS: Patients with cirrhosis (n=112) (mean age 41.8±12 years, 58.5% males) were followed up for median duration of 5.7 years interquartile range [IQR 3.5-5.7], with five-year survival rate of 77%. On serial BCA, ΔLD (p=0.029) and ΔFD (p=0.003) emerged as significant predictors of survival, whereas ΔFM (p=0.479), ΔFFM (p=0.245) and ΔBMI (p=0.949) were not. The area under curve of ΔLD and MELD score for predicting survival was 0.636 (0.5-0.773) and 0.664 (0.555-0.773), respectively. ΔFD<0.1 over one year had sensitivity and specificity of 70.4% and 56.5% to predict poor survival. The combination of ΔFD, MELD and ascites predicted five-year survival with an optimism-corrected c-statistic of 0.785. CONCLUSION: Among body composition parameters, changes in bone mineral density correlate best with survival and have prognostic relevance similar to that of ascites and MELD score.

Randomised clinical trial: effect of adding branched chain amino acids to exercise and standard-of-care on muscle mass in cirrhotic patients with sarcopenia.

BACKGROUND: The role of branched-chain amino acids (BCAA) in improving muscle mass in cirrhosis is presently debatable. AIMS: To evaluate the role of BCAA in improving muscle mass in a double-blind randomized placebo-controlled trial in patients with cirrhosis having sarcopenia. METHODS: Consecutive patients with cirrhosis with Child-Pugh score < 10 and sarcopenia were randomized to receive either 12 g/day of BCAA orally or a placebo (1:1) for 6 months in addition to a home-based exercise program (30 min/day), dietary counselling and standard medical therapy. Sarcopenia was defined according to gender-specific axial skeletal muscle index (SMI) cut-offs. The primary endpoint was a change in muscle mass based on CT scan (SMI) after 6 months of supplementation. RESULTS: Sixty patients [mean age 41.6 ± 9.9 years; males (66.6%) of predominantly viral (40%) and alcohol-related (31.7%) cirrhosis] were randomized. Baseline clinical and demographic characters were similar except MELD score (10.2 ± 2.8 vs. 12.2 ± 3.5, p = 0.02) and calorie intake (1838.1 kcal ± 631.5 vs. 2217.5 kcal ± 707.3, p = 0.03), both being higher in the placebo arm. After adjusting for both baseline confounders, baseline SMI and protein intake, the change in SMI at 6 months was similar in both groups [mean adjusted difference (MAD) + 0.84, CI - 2.9; + 1.2, p = 0.42] by intention-to-treat analysis. The secondary outcomes including change in handgrip strength (p = 0.65), 6-m gait speed (p = 0.20), 6-min walk distance (p = 0.39) were similar in both arms. Four patients had minor adverse events in each arm. CONCLUSION: Addition of BCAA to exercise, dietary counselling and standard medical therapy did not improve muscle mass in patients with cirrhosis having sarcopenia. (CTRI/2019/05/019269).

Exploiting endophytic microbes as micro-factories for plant secondary metabolite production.

Plant secondary metabolites have significant potential applications in a wide range of pharmaceutical, food, and cosmetic industries by providing new chemistries and compounds. However, direct isolation of such compounds from plants has resulted in over-harvesting and loss of biodiversity, currently threatening several medicinal plant species to extinction. With the breakthrough report of taxol production by an endophytic fungus of Taxus brevifolia, a new era in natural product research was established. Since then, the ability of endophytic microbes to produce metabolites similar to those produced by their host plants has been discovered. The plant "endosphere" represents a rich and unique biological niche inhabited by organisms capable of producing a range of desired compounds. In addition, plants growing in diverse habitats and adverse environmental conditions represent a valuable reservoir for obtaining rare microbes with potential applications. Despite being an attractive and sustainable approach for obtaining economically important metabolites, the industrial exploitation of microbial endophytes for the production and isolation of plant secondary metabolites remains in its infancy. The present review provides an updated overview of the prospects, challenges, and possible solutions for using microbial endophytes as micro-factories for obtaining commercially important plant metabolites.Key points• Some "plant" metabolites are rather synthesized by the associated endophytes.• Challenges: Attenuation, silencing of BGCs, unculturability, complex cross-talk.• Solutions: Simulation of in planta habitat, advanced characterization methods.

Effect of Vitamin D Supplementation on Vitamin D Level and Bone Mineral Density in Patients With Cirrhosis: A Randomized Clinical Trial.

INTRODUCTION: In patients with cirrhosis, highly prevalent vitamin D deficiency and low bone mineral density (BMD) increase the burden of disease, and role of vitamin D supplementation is not clear. So, our aim was to determine the effect of vitamin D supplementation on vitamin D level and BMD in patients with cirrhosis. METHODS: Patients with cirrhosis (18-60 years) of any etiology were enrolled. We measured serum 25(OH)D, parathyroid hormone, thyroid-stimulating hormone, free T4, bone-specific alkaline phosphatase, insulin-like growth factor (IGF)-1, and health-related quality of life at entry and at 1 year; however, serum calcium was measured at 3-month interval. BMD was measured by dual-energy x-ray absorptiometry at lumbar spine and left hip neck at entry and after 1 year. Statistical analysis was performed according to intention-to-treat analysis. RESULTS: Of 390 screened patients with cirrhosis, 164 participants (82 in each group) were randomized. There was significant increase in 25(OH)D levels in intervention group after 1 year (33.7 [24.3-45.7] ng/mL vs 23.1 [17-28.2] ng/mL; P < 0.001) when compared with placebo. The mean difference in BMD at lumbar spine and left hip neck was not significantly changed after 1 year of intervention with vitamin D between both groups. There was no significant change in both the groups in levels of calcium, thyroid-stimulating hormone, parathyroid hormone, free T4, IGF-1, and bone-specific alkaline phosphatase and quality of life. DISCUSSION: Supplementation with vitamin D for 1 year improves vitamin D levels but did not result in improvement in BMD at lumbar spine and left hip neck in patients with cirrhosis.

A panoramic view on phytochemical, nutritional, and therapeutic attributes of Ziziphus mauritiana Lam.: A comprehensive review.

Ziziphus mauritiana (Rhamnaceae), commonly known as Indian jujube, is a pharmacologically diverse medicinal plant. A plethora of active phytochemical constituents of this plant has been revealed so far, namely, berberine, quercetin, kaempferol, sitosterol, stigmasterol, lanosterol, diosgenin, and so forth. Several studies demonstrated the exploration of pharmacological potential of various parts such as fruits, leaves, and stems of the plant as antioxidant, cytotoxic, antimicrobial, anti-diarrhoeal, antidepressant, immunomodulator, and hepatoprotective. This review gives a unique summary including phytochemistry, nutritional value, and significant pharmacological importance of Z. mauritiana. The literature search was carried out via search engine PubMed, Science Direct, and so on. The data were heterogeneous in terms of leaves, stem, roots, and fruits which were used for different experimental findings, which made the comparison a lengthy task. Study findings suggested that the extracts from this plant may possess numerous types of pharmacological activities. As the search for novel drugs from botanical sources continues, there is need for future investigations to isolate and characterize pharmacologically active agents that confer medicinal properties on Z. mauritiana, as well as to elucidate the structures of these agents by which they exert their healing properties and to scientifically validate the existing traditional practices concerning its health benefits.

Vitamin D Supplementation in Overweight/obese Asian Indian Women with Prediabetes Reduces Glycemic Measures and Truncal Subcutaneous Fat: A 78 Weeks Randomized Placebo-Controlled Trial (PREVENT-WIN Trial).

Vitamin D deficiency may contribute to etiology of type 2 diabetes in Asian Indians. The objectives of this study was to evaluate effect of vitamin D supplementation on glycemic profile and body composition in prediabetic and vitamin D deficient overweight/obese Asian Indian women. In this open-label randomized placebo-controlled trial (78 weeks duration), 121 females (aged 20-60 years) with prediabetes and vitamin D deficiency were randomly allocated in intervention (n, 61) and placebo (n, 60) groups. The primary outcome variables were fasting blood glucose (FBG), 2-h blood glucose post OGTT (2-h BG), hemoglobin A1c (HbA1C), and reversal to normoglycemia. In Intention-to-treat analysis, at the end of intervention, we observed significant decrease in FBG [-5.0 (-12.6-2.4), p = 0.04], 2-h blood glucose post OGTT [-11(-49.3-26.9), p = 0.02], hemoglobin A1c [-0.41 (5.89, 6.55), p = 0.05] and increase in 25(OH) D [7.5 (-6.0-20.9), p = 0.002] levels in intervention as compared to the placebo group. Changes in glycemic category based on FBG were as follows; intervention group: normal FBG, 58.6%; impaired fasting glucose (IFG), 39%; and type 2 diabetes mellitus (T2DM), 2.4%; placebo group: normal FBG, 48.8%; IFG, 46.3%; and T2DM, 4.9%. Changes in category of 2-hour glucose post OGTT after intervention were as follows; intervention group: normal glucose tolerance (NGT) 51.2% and prediabetes, 48.8%; placebo group: NGT, 43.9%; prediabetes, 53.7% and T2DM, 2.4%. After intervention, subscapular skinfold (visit Ist compared to visit IIIrd) and suprailiac skinfold (visit IInd compared to visit IIIrd) were significantly lower in intervention group vs. control group. In conclusion, we observed significant reduction in FBG, 2-hour glucose post OGTT, HbA1c, and truncal subcutaneous fat and reversal to normoglycemia in overweight/obese prediabetic vitamin D deficient Asian Indian women after 78 weeks of vitamin D supplementation.

Antioxidants for Pancreatic Functions in Chronic Pancreatitis: A Double-blind Randomized Placebo-controlled Pilot Study.

BACKGROUND: Antioxidants (AO) supplementation in chronic pancreatitis (CP) has been evaluated for pain. But it is not clear whether AO in CP have an effect on pancreatic functions and other clinical outcomes. We evaluated effect of AO on endocrine function in CP. MATERIALS AND METHODS: Double-blind placebo (PL)-controlled randomized pilot study on 107 patients with CP assigned to receive daily combined AO or PL for 6 months. Primary outcome was: improvement in endocrine function (Homeostasis Model Assessment-Insulin Resistance). Secondary outcome measures were: improvement in C-peptide, Qualitative Insulin Sensitivity Check Index, exocrine pancreatic function (fecal elastase), surrogate markers of fibrosis (platelet-derived growth factor BB, transforming growth factor-ß1, α-smooth muscle actin), quality of life (QOL), pain, nutritional status, markers of oxidative stress (OS), AO status, and inflammation. RESULTS: There was an increase in levels of serum selenium (107.2±26.9 to 109.7±26.9 vs. 104.1±28.6 to 124.0±33.6 µg/L, P=0.022) and serum vitamin E [0.58 (range, 0.27-3.22) to 0.66 (range, 0.34-1.98) vs. 0.63 (range, 0.28-1.73) to 1.09 (range, 0.25-2.91) mg/dL, P=0.001] in the AO than the PL group. However, no significant differences were observed between groups in any of the primary or secondary outcome measures. CONCLUSIONS: Supplementation with AO to patients with CP causes a sustained increase in blood levels of AO; however, it has no addition benefit over PL on endocrine and exocrine functions, markers of fibrosis, OS and inflammation, nutritional status, pain and QOL. Further larger studies with adequate sample size are required.

Lifestyle Intervention Framework for Obese Patients with Non-alcoholic Fatty Liver Disease - a Tool for Health Professionals in Resource Constraint Settings.

Purpose Non-alcoholic fatty liver disease (NAFLD), is recognized as a health care burden worldwide. Lifestyle modification remains the first line of treatment. However, the real challenge is ensuring the patient's adherence to lifestyle modification measures, especially in hospitals with resource-limited settings. Methods We developed a six-month-long, dietitian-led, hospital-based, lifestyle intervention framework for obese NAFLD patients and evaluated its content. Literature review, interviews, and discussions with 10 health experts (general physicians, dietitians/nutritionists, gastroenterologists, and a clinical psychologist) and 45 NAFLD patients (35 in Phase I and 10 in Phase II) in a tertiary hospital of India were carried out. Results The lifestyle intervention framework has unique features, such as an intensive nature to ensure adherence, a comprehensive educational format with clear guidelines, the customization of a prescription as per individual patient requirements, and a holistic approach to inculcate self-monitoring and behavioral change in NAFLD patients. Conclusion Health professionals worldwide can use this lifestyle intervention framework to develop counseling interventions for better adherence among obese NAFLD patients.

Is Transdermal Multivitamin Patch Effective in Gastric Bypass Patients?

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) patients are recommended to take multiple oral vitamin supplements daily. Transdermal multivitamin patches are being advertised as an alternative for use in bariatric patients with no data to support their efficacy. The purpose of this study was to evaluate response to daily transdermal use of multivitamin patch after LRYGB and to compare them with a control group of similar patients who used oral supplements. METHODS: A retrospective review was carried out on patients who had LRYGB at a community hospital from February 2015 to February 2019. Patients who had completed preoperative and annual postoperative bariatric laboratory tests were included. They were divided into patch and pill (control) group. RESULTS: Seventeen patients were included in the patch and 27 in the pill group. Patients in each group used either patch or pills for 12 months and they were 1 year post LRYGB. Fourteen patients (82.35%) in patch group and 11 patients (40.74%) in pill group had at least 1 deficiency at annual postoperative blood work (P = .0116). Vitamin D deficiency was seen in 81% patients in patch group vs 36% in the pill group (P = .0092). Statistically significant lower postoperative serum concentrations of vitamin D, B1, and B12 were seen in the patch group. CONCLUSIONS: Multivitamin patch users are more likely to have vitamin D deficiency and lower serum concentration of various vitamins and minerals. Future large studies are needed on the efficacy of multivitamin patches before they can be recommended to bariatric patient population.

Vitamin D and calcium supplementation, skeletal muscle strength and serum testosterone in young healthy adult males: Randomized control trial.

BACKGROUND: Cholecalciferol and/or calcium supplementation might increase skeletal muscle strength and serum testosterone in young adult males. OBJECTIVE: We performed a randomized control trial assessing the effect of cholecalciferol/calcium on skeletal muscle strength and serum testosterone in vitamin D deficient young males. DESIGN: Two-by-two factorial RCT. SUBJECT AND INTERVENTION: Two-hundred and twenty-eight young males were block-randomized to (i) double-placebo, (ii) calcium/placebo, (iii) cholecalciferol/placebo and (iv) cholecalciferol/calcium. Doses for cholecalciferol were 60 000 IU/wk for 8 weeks followed by 60 000 IU/fortnightly, and doses for elemental calcium were 500 mg/twice daily for 6 months. A total of 180 subjects completed the study protocol. Their  ean age, body mass index and baseline 25(OH)D were 20.2 ± 2.2 years, 23.0 ± 3.6 kg/m2 and 21.5 ± 9.5 nmol/L, respectively. MEASUREMENTS: Handgrip (primary outcome), pinch-grip strength, distance walked in 6 minutes, dyspnoea-score, quality of life by Short Form 36, serum 25(OH)D, 1,25(OH)2 D, iPTH, total testosterone and free androgen index (FAI). RESULTS: After intervention, mean serum 25(OH)D was >75.0 nmol/L in cholecalciferol groups. However, the handgrip strength (29.7 ± 4.4, 29.3 ± 4.6, 30.6 ± 5.0 and 28.8 ± 4.3 kg, P = .28) was comparable in the 4 groups. Subgroups analysis among subjects with baseline serum 25OH)D < 25.0 and <12.0 nmol/L showed similar results. The mean serum testosterone decreased significantly at 6 months; however, delta change was similar in 4 groups. Change in handgrip strength and other outcomes was similar in 4 groups with and without adjustment for delta testosterone and FAI. CONCLUSIONS: Six months of cholecalciferol/calcium supplementation had no significant effect on skeletal muscle strength and serum testosterone in young adult males.

PI3K-mediated proliferation of fibroblasts by Calendula officinalis tincture: implication in wound healing.

Calendula officinalis, a member of the Asteraceae family, is a flowering plant and has been used for its antibacterial, antifungal, antiviral, antiinflammatory, anticancer and wound healing activity. The mode of action of C. officinalis tincture on wound healing is poorly understood. Here, we investigated the role of C. officinalis tincture (CDOT) on cell viability and wound closure. C. officinalis tincture stimulated both proliferation and migration of fibroblasts in a statistically significant manner in a PI3K-dependent pathway. The increase in phosphorylation of FAK (Tyr 397) and Akt (Ser 473) was detected after treatment of CDOT. Inhibition of the PI3K pathway by wortmannin and LY294002 decreased both cell proliferation and cell migration. HPLC-ESI MS revealed the presence of flavonol glycosides as the major compounds of CDOT. Altogether, our results showed that CDOT potentiated wound healing by stimulating proliferation and migration of fibroblast in a PI3K-dependent pathway, and the identified compounds are likely to be responsible for wound healing activity.

Effect of oral glutamine supplementation on gut permeability and endotoxemia in patients with severe acute pancreatitis: a randomized controlled trial.

OBJECTIVE: The aim of this study is to evaluate the effect of oral glutamine (GL) supplementation on gut permeability and endotoxemia (surrogate end point) in patients with severe acute pancreatitis. METHODS: In a randomized controlled trial, patients were randomized to be given placebo or GL for 7 days. The primary outcome measures include the effect on gut permeability (assessed by lactulose/mannitol excretion in urine and endotoxemia assessed by endotoxin core antibodies type IgG and IgM (EndoCab IgG and IgM). The secondary outcome measures include infectious complications, mortality, total hospital/intensive care unit stay, C-reactive protein, and prealbumin levels. RESULTS: Patients were assigned to GL (n = 41) and placebo (n = 39) groups. There was no change in gut permeability after the intervention. However, the EndoCab IgM levels increased significantly (33 [4, 175] to 40 [8, 350] GMU/mL; P = 0.0164) and the C-reactive protein levels decreased significantly (133 [1, 287] to 88 [1, 267] ng/mL; P = 0.0236) in the GL group. No difference was observed in infectious complication, prealbumin value, hospital/intensive care unit stay, and mortality in both groups. CONCLUSIONS: No significant trend was identified for an effect of GL on gut permeability. Decreased inflammation and endotoxemia did not translate into reduced infectious complications in severe acute pancreatitis. However, the study was underpowered to detect the aforementioned difference (trial registration: CTRI/2009/000945).

Effect of antioxidant supplementation on surrogate markers of fibrosis in chronic pancreatitis: a randomized, placebo-controlled trial.

OBJECTIVES: This study aimed to determine the effect of antioxidant (AO) supplementation on surrogate markers of fibrosis in patients with chronic pancreatitis (CP). METHODS: In a randomized, placebo (PL)-controlled trial, patients with CP were randomized to groups that were given PL or AO for 3 months. Outcome measures were change in serum levels of transforming growth factor ß1 and platelet-derived growth factor AA (PDGF-AA) (primary outcome) as well as blood markers of oxidative stress (thiobarbituric acid-reactive substances) and AO status (ferric-reducing ability of plasma) (secondary outcome). Pain relief and analgesic requirement was also recorded. RESULTS: Patients (n = 61; mean [SD] age, 35.2 [10.0]; male patients, 43) were assigned to AO (n = 31) and PL (n = 30) groups. The median (range) percent reduction from baseline to 3 months in levels of PDGF-AA (17.1% [-25.3% to 88.7%] vs 2.8% [-243.1% to 30.2%]; P = 0.001), transforming growth factor ß1 (P = 0.573), and thiobarbituric acid-reactive substances (P = 0.207) as well as percent increment from baseline to 3 months in ferric-reducing ability of plasma (P = 0.003) were higher in the AO group compared with the PL group. Proportion of patients who had both reduced PDGF-AA and reduced pain was greater in AO as compared with PL group (17/31 vs 9/30, P = 0.05) CONCLUSIONS: Reduction in markers of fibrosis (PDGF-AA) translated into clinical outcome (reduction in pain and analgesic requirements) in those supplemented with AOs in CP (trial registration, CTRI/2011/05/001747).

Effect of antioxidant therapy on hospital stay and complications in patients with early acute pancreatitis: a randomised controlled trial.

BACKGROUND: Oxidative stress (OS) in acute pancreatitis (AP) has been pathologically linked with the systemic inflammatory response and antioxidant supplementation may have a clinical benefit. METHODS: In this prospective, randomised open label, controlled pilot study, patients admitted within 72 hours of onset of pain were randomised to receive either placebo (only standard medical treatment; SMT) or antioxidants (vitamin C 500 mg, N-acetyl cysteine 200 mg 8 hourly and antoxyl forte 1 capsule hourly with standard medical treatment; SMT + AO) daily, following informed consent. Patients with co-morbid illness and pregnancy were excluded. Primary efficacy measures were length of hospital stay and complications whilst secondary measures were biochemical markers of oxidative stress (thiobarbituric acid reactive substances [TBARS] and superoxide dismutase [SOD] and total antioxidant capacity [TAC] and vitamin C) at Days 1, 3 and 7. RESULTS: Of 53 patients, 30 patients were randomised to SMT and 23 patients to SMT + AO. The mean duration of hospital stay in the SMT group (10.3 +/- 7 days) was more compared to SMT + AOT (7.2 +/- 5 days), but was not statistically significant (p=0.07), complications were similar in the 2 groups. At Day 7, OS was significantly lower in the SMT + AO group when compared with the SMT group (TBARS, p=0.05; SOD, p=0.03) with a significant increase in FRAP and vitamin C (p=0.01). CONCLUSIONS: Antioxidant supplementation may decrease the length of hospital stay and complication rate in patients with AP, but a larger clinical trial is needed to support this hypothesis. Further, it decreased the OS and improved the antioxidant status in patients with AP.

Dietary counseling versus dietary supplements for malnutrition in chronic pancreatitis: a randomized controlled trial.

BACKGROUND & AIMS: Up to 50% of patients with chronic pancreatitis (CP) are malnourished. There are limited data on the role of dietary intervention in improving the nutritional status of such patients. The aim was to compare the efficacy of medium chain triglyceride (MCT)-enriched commercial dietary supplements with dietary counseling for homemade food in the management of malnutrition in patients with CP. METHODS: In a randomized controlled trial, consecutive undernourished patients with CP (body mass index [BMI] <18.5 kg/m(2)) at a tertiary care hospital were randomized to receive either dietary counseling for regular homemade food or commercial MCT-enriched dietary supplements for a period of 3 months to compensate for the dietary calorie deficit. All patients received standard management for CP including pancreatic enzyme supplements. Primary outcome measure was improvement in BMI. RESULTS: Sixty malnourished patients with CP were randomized to counseling group (n = 29; mean age, 32 +/- 10 years; male, 83%) and supplementation group (n = 31; mean age, 28 +/- 10 years; male, 84%). BMI increased in both the counseling group and supplementation group (17.2 +/- 1.7 vs 18.1 +/- 1.8 kg/m(2), P = .001; 16.7 +/- 1.6 vs 18.2 +/- 1.6 kg/m(2), P = .001). There were similar improvements in triceps skinfold thickness, dietary intake, fecal fat, and pain score during a period of 3 months in both groups. There was, however, no significant difference between the counseling and supplementation groups with regard to any of the outcome measures. CONCLUSIONS: Dietary counseling for a balanced homemade diet is as good as commercial food supplements in improving malnutrition in patients with CP.

Pattern of 25-hydroxy vitamin D response at short (2 month) and long (1 year) interval after 8 weeks of oral supplementation with cholecalciferol in Asian Indians with chronic hypovitaminosis D.

Hypovitaminosis D is common in Asian Indians. Physicians often prescribe 1500 mug (60 000 IU) cholecalciferol per week for 8 weeks for vitamin D deficiency in India. Its efficacy to increase serum 25-hydroxy vitamin D (25(OH)D) over short (2 months) and long (1 year) term is not known. We supplemented a group of twenty-eight apparently healthy Asian Indians detected to have low serum 25(OH)D (mean 13.5 (sd 3.0) nmol/l) on screening during January-March 2005. Serum parathyroid hormone (PTH) level was supranormal in 30 % of them. Oral supplementation included 1500 mug cholecalciferol per week and 1g elemental Ca daily for 8 weeks. Serum 25(OH)D, total Ca, inorganic P and intact (i) PTH were reassessed in twenty-three subjects (twelve females and eleven males) who had follow up at both 8 weeks and 1 year. At 8 weeks the mean 25(OH)D levels increased to 82.4 (sd 20.7) nmol/l and serum PTH normalized in all. Twenty-two of the twenty-three subjects had 25(OH)D levels>49.9 nmol/l. At 1 year, though the mean 25(OH)D level of 24.7 (sd 10.9) nmol/l was significantly higher than the baseline, all subjects were 25(OH)D deficient. Five subjects with supranormal iPTH at baseline showed recurrence of biochemical hyperparathyroidism. Thus, with 8 weeks of cholecalciferol supplementation in Asian Indians with chronic hypovitaminosis D, mean serum 25(OH)D levels would be normalized and serum PTH value would be reduced to half. However, such quick supplementation would not maintain their 25(OH)D levels in the sufficient range for 1 year. For sustained improvement in 25(OH)D levels vitamin D supplementation has to be ongoing after the initial cholecalciferol loading.

Nutrition in the management of hepatic encephalopathy.

Nutritional factors play a major role both in the pathogenesis as well as management of hepatic encephalopathy (HE). Physicians treating patients with chronic liver disease often restrict the intake of dietary protein to prevent a rise in blood ammonia levels. The role of protein restriction in patients with chronic hepatic encephalopathy (CHE) has been questioned recently as the efficacy of protein withdrawal in patients with CHE has never been subjected to a controlled trial. Evidence suggests that protein intake plays only a limited role in precipitating encephalopathy. In fact, measures taken to suppress endogenous protein breakdown are more effective than dietary restrictions in reducing the load of amino acids on the decompensated liver. A protein intake of less than 40 g per day, as has been indicated, contributes to a negative nitrogen balance, which along with increased endogenous protein breakdown, worsens encephalopathy. A positive nitrogen balance may have positive effects on encephalopathy. Rather, depressed plasma branched-chain amino acid (BCAA) levels, implicated in the pathogenesis of HE, also supervene in cirrhosis only when malnutrition is present as well. Therefore, the emphasis in the nutritional management of patients with HE should not be on the reduction of protein intake. Instead, the goal should be to promote synthesis by making available ample amounts of amino acids, while instituting other measures to reverse the ongoing catabolism. Different protein sources have varying effects on HE and efforts should be made to identify the most tolerated protein source to prevent malnutrition and maintain these patients on a long-term basis.
