Association between vitamin B1 intake and hyperuricemia in adults.

Studies investigating the relationship between dietary vitamin B1 intake and risk of Hyperuricemia (HU) are scarce, the present study aimed to examine the association of dietary vitamin B1 intake and HU among adults. This cross-sectional study included 5750 adults whose data derived from National Health and Nutrition Examination Survey (NHANES) from March 2017 to March 2020. The dietary intake of vitamin B1 was assessed using 24-h dietary recall interviews. The characteristics of study participants were grouped into five levels according to the levels of vitamin B1 quintile. Multivariate logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of HU, according to the vitamin B1 intake quintile for male and female separately. The dose-response relationship was determined by the restricted cubic spline (RCS). Smoothed curve fitting was used to assess serum uric acid concentration versus dietary vitamin B1 intake in the study population. The prevalence of hyperuricemia was 18.90% (20.15% and 17.79% for males and females, respectively) in the United States from March 2017 to March 2020. Multiple logistic regression analyses showed that in the male population, the HU ratio (OR) of vitamin B1 intake in Q2 to Q5 compared with the lowest quintile (Q1) was 0.75 (95% CI 0.52, 1.09), 0.70 (95% CI 0.48, 1.02), 0.66 (95% CI 0.44, 0.99) and 0.55 (95% CI 0.34, 0.90). The P for trend was 0.028. In women, the ORs for vitamin B1 intake Q2 to Q5 were 0.87 (95% CI 0.64, 1.19), 0.97 (0.68-1.38), 1.05 (0.69-1.60) and 0.75 (0.42-1.34), respectively. The P for trend was 0.876. The RCS curve revealed a linear relationship between vitamin B1 intake and the risk of hyperuricemia in men (P nonlinear = 0.401). Smoothed curve fitting demonstrated a negative association between vitamin B1 intake and serum uric acid concentration in men, whereas there was no significant association between dietary vitamin B1 intake and the risk of hyperuricemia in women. In the US adult population, dietary vitamin B1 intake was negatively associated with hyperuricemia in males.

Secondary hemophagocytic lymphohistiocytosis induced by cholecystitis: A case report and a review of the literature.

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening disease resulting from excessive activation and non-malignant proliferation of macrophages and T lymphocytes. Whether it can be caused by cholecystitis has not yet been reported in the world. CASE REPORT: A 4-year-old girl was admitted to hospital with cholecystitis. The patient was diagnosed with hemophagocytic lymphohistiocytosis after 3days of admission based on the results of laboratory tests showing hypofibrinogenemia, hypertriglyceridemia, thrombocytopenia, anemia and leukopenia. CONCLUSIONS: From this case experience, if a timely symptomatic treatment is given, the condition of the patient with secondary HLH can be alleviated. This is the first report of cholecystitis-induced hemophagocytic syndrome in the world also.

Stir-fried white pepper can treat diarrhea in infants and children efficiently: a randomized controlled trial.

We evaluated the efficacy and safety of stir-fried white pepper in the treatment of infant and children diarrhea. This was a randomized trial conducted in the pediatric emergency department of the hospital affiliated to Jining Medical College. One hundred seventy four patients were selected from outpatients from 2011 to 2012. Participants were randomly assigned to treatment with stir-fried white pepper (n = 88) or montmorillonite powder (n = 86). The proportions of chronic diarrhea patients (n = 52) showing success of treatment were similar for both groups. There were great differences between the two groups in acute diarrhea (n = 62) and persistent diarrhea (n = 60), and the cure rate of stir-fried white pepper was higher than montmorillonite powder in both groups. The prescription of stir-fried white pepper significantly decreased the frequency of diarrhea in infants and children under 2.5 years with diarrhea compared to treatment with montmorillonite powder, especially for the patients with acute diarrhea or persistent diarrhea.

Acute immune thrombocytopenic purpura as adverse reaction to oral polio vaccine (OPV).

A case of acute immune thrombocytopenic purpura following oral polio vaccine (OPV) is reported. An 82-d-old infant developed purpura at the same day after the second dose of oral polio vaccine. Until the time of hospital admission, the male infant had been in good health and had not received any drugs, and the possible causes of this condition were excluded. His platelet count was 13×10(9)/L. Platelet-associated IgG was elevated, but the amount of megakaryocytes in bone marrow aspirates was within the normal range, suggesting immune mechanism-associated thrombocytopenia. The infant recovered with the proper treatment within 30 d. Attention should be paid to OPV-associated thrombocytopenia, though it seems to be less frequent than after natural infections.

[Correlation of lymphoblastic PPAR-gamma mRNA expression with plasma IL-13 contents in children with acute idiopathic thrombocytopenic purpura].

OBJECTIVE: PPAR-gamma is associated with the differentiation, apoptosis, proliferation and cytokine secretion of immunologic cells. This study investigated peripheral blood lymphoblastic PPAR-gamma mRNA expression and its correlation with plasma IL-13 contents in children with acute idiopathic thrombocytopenic purpura (ITP). METHODS: Fifty-three children with acute ITP who were in line with the standard test between September 2007 and July 2008 were enrolled. Fifty healthy children during the same period were used as the control group. PPAR-gamma mRNA expression in peripheral blood lymphocytes were detected by RT-PCR. Plasma IL-13 contents were detected using ELISA. RESULTS: PPAR-gamma mRNA expression in peripheral blood lymphocytes from acute ITP children were significantly higher than that in the control group (0.78 +/- 0.03 vs 0.52 +/- 0.05; P< 0.05). Plasma IL-13 contents in children with acute ITP were also significantly higher than those in the control group (160.21 +/- 34.26 pg/mL vs 121.42 +/- 12.69 pg/mL; P< 0.05). There was a positive correlation between plasma IL-13 level and lymphoblastic PPAR-gamma mRNA expression in children with ITP (r=0.89, P< 0.05). CONCLUSIONS: PPAR-gamma mRNA expression in peripheral blood lymphocytes increased and were positively correlated with plasma IL-13 contents in children with acute ITP, suggesting that PPAR-gamma and IL-13 might participate in the pathogenesis of acute ITP.
