Whole-protein enteral nutrition formula supplementation reduces Escherichia and improves intestinal barrier function in HIV-infected immunological nonresponders.

People living with human immunodeficiency virus (PLWH) have persistent malnutrition, intestinal barrier dysfunction, and gut microbial imbalance. The interplay between gut microbiota and nutrients is involved in the immune reconstitution of PLWH. To evaluate the effects of whole-protein enteral nutrition formula supplementation on T-cell levels, intestinal barrier function, nutritional status, and gut microbiota composition in human immunodeficiency virus (HIV)-infected immunological nonresponders (INRs) who failed to normalize CD4+ T-cell counts, with a number <350 cells/µL, a pilot study was carried out in 13 HIV-infected INRs undergoing antiretroviral therapy who received a 3-month phase supplementation of 200 mL/200 kcal/45 g whole-protein enteral nutrition formula once daily. Our primary endpoint was increased CD4+ T-cell counts. Secondary outcome parameters were changes in intestinal barrier function, nutritional status, and gut microbiota composition. We showed that CD4+ T-cell counts of HIV-infected INRs increased significantly after the 3-month supplementation. Dietary supplementation for 3 months improved the intestinal barrier function and nutritional status of HIV-infected INRs. Furthermore, the enteral nutrition formula significantly decreased the relative abundance of Escherichia at the genus level and increased the alpha diversity of gut microbiota in HIV-infected INRs. The findings demonstrated that the whole-protein enteral nutrition formula aids in reducing Escherichia and improving intestinal barrier function in HIV-infected INRs. This study provides insight into the role of nutrients in the improvement of immune reconstitution in HIV-infected INRs. This study is registered in the Chinese Clinical Trial Registry (Document No. ChiCTR2000037839; http://www.chictr.org.cn/index.aspx).

[Effect of electroacupuncture at antagonistic muscle and agonistic muscle on motor function in patients with upper-extremity spasticity after stroke].

OBJECTIVE: To compare the improvement effect between simultaneous electroacupuncture at antagonistic muscle and agonistic muscle and simple electroacupuncture at antagonistic muscle on spasticity degree, upper-extremity motor function and activity of daily living in patients with upper-extremity spasticity after stroke. METHODS: A total of 60 patients with upper-extremity spasticity after stroke were randomized into a comprehensive group (30 cases, 1 case dropped off) and an antagonistic muscle group (30 cases, 2 cases dropped off). In the antagonistic muscle group, acupuncture was applied at Jianyu (LI 15), Binao (LI 14), Zhouliao (LI 12), Shousanli (LI 10), Waiguan (TE 5) and Houxi (SI 3), electric stimulation was attached to Jianyu (LI 15)-Binao (LI 14), Zhouliao (LI 12)-Shousanli (LI 10) and Waiguan (TE 5)-Houxi (SI 3), with discontinuous wave, 15 Hz in frequency. On the basis of the treatment in the antagonistic muscle group, acupuncture was applied at Tianquan (PC 2), Chize (LU 5), Jianshi (PC 5) and Daling (PC 7) in the comprehensive group, electric stimulation was attached to Tianquan (PC 2)-Chize (LU 5) and Jianshi (PC 5)-Daling (PC 7), with continuous wave, 5 Hz in frequency. The treatment was given once a day, 6 days a week for 4 weeks in the two groups. Before and after treatment, the scores of modified Ashworth scale (MAS), Fugl-Meyer assessment upper extremity scale (FMA-UE) and modified Barthel index (MBI) scale were observed in the two groups. RESULTS: Compared before treatment, the MAS scores of elbow flexors and wrist flexors after treatment were decreased (P<0.05), the scores of FMA-UE and MBI scale after treatment were increased in the two groups (P<0.05). The scores of FMA-UE and MBI scale after treatment in the comprehensive group were higher than those in the antagonistic muscle group (P<0.05). CONCLUSION: Simultaneous electroacupuncture at antagonistic muscle and agonistic muscle and simple electroacupuncture at antagonistic muscle can both improve the spasticity degree in patients with upper-extremity spasticity after stroke, however, the former can better restore motor function and improve activity of daily living.

Pre-Digested Protein Enteral Nutritional Supplementation Enhances Recovery of CD4+ T Cells and Repair of Intestinal Barrier in HIV-Infected Immunological Non-Responders.

AIDS patients with immune non-response are prone to malnutrition, intestinal barrier damage, thus aggravating chronic immune activation and inflammation. However, nutritional interventions targeting malnutrition may be beneficial to restore immune function, improve clinical outcomes, and reduce mortality remains largely unclear. This work aimed to evaluate the efficacy of a nutritional supplement in HIV-infected immune non-responders (INRs). The subjects received oral supplementation of a pre-digested protein nutrition formula for three months. We show that the CD4+ T and CD8+ T cell counts were significantly increased after supplementation of the pre-digested enteral nutritional supplement. Among all pro-inflammatory cytokines in the serum, only IL-1ß level was significantly decreased, while TNF-ß was significantly increased (P < 0.05). The levels of intestinal mucosal damage markers, diamine oxidase (DAO), D-lactic acid (D-lactate), and lipopolysaccharide (LPS), decreased significantly (P < 0.05) after the nutritional intervention. Moreover, at month 3 after the intervention, the body weight, body mass index, albumin, and hemoglobin of all subjects were significantly increased (P < 0.05). The correlation analysis demonstrated a significantly negative correlation of CD4+ T cell count with levels of DAO (r = -0.343, P = 0.004), D-lactate (r = -0.250, P = 0.037), respectively, and a significantly positive correlation of IL-1ß level with levels of DAO (r = 0.445, P < 0.001), D-lactate (r = 0.523, P < 0.001), and LPS (r = 0.622, P < 0.001). We conclude that the pre-digested enteral nutrition supplement is effective for HIV-infected INRs.

Adefovir dipivoxil induced hypophosphatemic osteomalacia in chronic hepatitis B: a comparative study of Chinese and foreign case series.

BACKGROUND: Adefovir dipivoxil (ADV)-induced renal tubular dysfunction and hypophosphatemic osteomalacia (HO) have been given great consideration in the past few years. However, no standard guidance is available due to a lack of powerful evidence from appropriate long-term prospective case-control studies and variations in the definition of renal adverse events. The aim of this study is to clarify clinical features of ADV-related HO in Chinese chronic hepatitis B patients with long-term ADV treatment in Chinese and non-Chinese comparative case series. METHODS: Retrieval of case reports was based on Pubmed, CNKI, Wan Fang and VIP databases using the key words adefovir dipivoxil, hypophosphatemia, osteomalacia and Fanconi syndrome. We divided patients into Chinese (C group) and Foreign (F group) groups according to their nationality. Comparisons involving demographics, clinical manifestations, tests, treatment and prognosis were conducted between the two groups. RESULTS: Of the patients screened, 120 Chinese patients were identified in the C group, and 32 non-Chinese patients were identified in the F group. The average age of the C group was younger than that of the F group (51.89 years ±10.96 years versus 56.47 years ±11.36 years, t = - 2.084, P = 0.039). No significant difference was found in gender (male to female, 3.29:1 versus 3:1, χ 2 = 0.039, P = 0.844). Although there was no significant difference in the duration of ADV therapy before ostalgia onset, the C group tended to develop adverse events earlier, by 2-3 years, while the F group developed adverse events at 4-5 years (Z = - 1.517, P = 0.129). Prognosis was good after adjustment of the ADV dose and supplemental administration of phosphate and calcitriol. Time to resolution of tubular dysfunction was commenced at the first month, and Chinese patients were more prone to recover in the first 3 months than non-Chinese patients (91.3% of patients in the C group versus 56.3% in the F group, Z = - 3.013, P = 0.003). CONCLUSIONS: Sufficient attention is required for middle-aged males before and during exposure to long-term ADV therapy, regardless of nationality. The clinical picture, laboratory and radiograph alterations are important clues for those patients and are usually characterized by polyarthralgia, renal tubular dysfunction and mineralization defects. Implementation of an early renal tubular injury index is recommended for patients with higher risk, which would prevent further renal injury.

[Meta-analysis on acupuncture for treatment of depression in patients of poststroke].

OBJECTIVE: To assess therapeutic effect and the safety of acupuncture for treatment of the depression in patients of poststroke. METHODS: The clinical research documents in recent 10 years of acupuncture for treatment of depression in patients of poststroke were retrieved, the homogeneity test was used and the effect amount was complicated in the clinical randomized controlled trials (RCT) documents which had been adopted in the Meta-analysis, and furthermore the Meta-analysis was used in the Hamilton Depression Scale (HAMD) score of both acupuncture group and medication group after treatment. RESULTS: Seventeen RCT heterogeneity test results which were adopted in the study indicated that chi2 = 21.98, P = 0.14, proved that they had homogeneity, and fixed effect model was adopted to analyse, after combination, OR = 2.54, 95% confidence interval was (1.91, 3.38), according to Z test, Z = 6.41, P < 0.00001, the diamond was in the right side of the vertical line, indicated that there was a significant difference in the therapeutic effect between the acupuncture group and the medication group. The evaluation of the influence of acupuncture on HAMD indicated that there was a significant difference between the acupuncture group and the medication group. CONCLUSION: The therapeutic effect of acupuncture for treatment of the depression in patients of poststroke is superior to other common medicine with safety, but it still needs more large sample RCTs to verify.
