BACKGROUND/AIMS: L-carnitine not only alleviates hyperammonemia and reduces muscle cramps in patients with liver cirrhosis, but also improves anemia in patients with chronic hepatitis and renal dysfunction. This study prospectively evaluated the preventative efficacy of L-carnitine supplementation against hemolytic anemia during antiviral treatment using ribavirin in patients with hepatitis C virus (HCV)-related chronic liver disease. METHODS: A total of 41 patients with chronic hepatitis were consecutively enrolled in this study. Group A (n=22) received sofosbuvir plus ribavirin for 3 months, whereas group B (n=19) was treated with sofosbuvir, ribavirin, and L-carnitine. Hemoglobin concentration changes, the effects of antiviral treatment, and the health status of patients were analyzed using short form-8 questionnaires. RESULTS: A significantly smaller decrease in hemoglobin concentration was observed in group B compared to group A at every time point. Moreover, the prescribed dose intensity of ribavirin in group B was higher than that of group A, resulting in a higher ratio of sustained virological response (SVR) 24 in group B compared with group A. The physical function of patients in group B was also significantly improved compared to group A at the end of antiviral treatment. CONCLUSIONS: L-carnitine supplementation alleviates ribavirin-induced hemolytic anemia in patients with HCV and helps relieve the physical burden of treatment with ribavirin-containing regimens. These advantages significantly increase the likelihood of achieving SVR.

The study analyzes the medication rules of Xin'an Wang's internal medicine for treating stomach cramps by data mining technology,in order to provide reference for clinical medication. Through the summarization of the medical cases of stomach cramps treated by Xin'an Wang's doctors( Wang Ren-zhi,Wang Zhong-qi,Wang Le-tao),statistics was made for the frequency of symptoms,signs,syndromes and drugs in Office 2010. Apriori algorithm in IBM SPSS Modeler 14. 1,and SPSS Statistics 22. 0 were used for association rule analysis and cluster analysis. The results showed that the 310 prescriptions collected involved totally 322 syndromes( including symptoms and signs) and 336 drugs,with the cumulative dose of 4 072 times; the symptoms were correlated to the spleen and stomach,liver and gallbladder,and the heart system; syndrome differentiation was mainly based on liver-Qi invasion of the stomach,diet impairment to the stomach,deficiency of spleen and stomach and cold syndrome; commonly used drugs were Qi regulating drugs,phlegm eliminating drugs and blood circulation promoting and stasis removing drugs; high-frequency drug complex network diagram showed that Pinelliae Rhizoma,Aurantii Fructus,Trichosanthis Fructus,Allii Macrostemonis Bulbus were closely related; the analysis showed 12,20,and 17 two,three,and four association rules; cluster analysis showed 10 pairs of Trichosanthis Fructus-Allii Macrostemonis Bulbus,Pinelliae Rhizoma-Aurantii Fructus,and Aspongopus-Toosendan Fructus drug combinations. According to Xin' an Wang's doctors,stomach cramps are closely related to liver and spleen,Qi stagnation,phlegm and blood stasis are the standard.Xin'an Wang's doctors give the first priority on " deoppilation",focus on soothing the liver and spleen,activating Qi and eliminating phlegm,and promoting blood circulation,and refer to use modified Xiaoxianxiong Decoction and modified Gualou Xiebai Banxia Decoction based on symptoms.

BACKGROUND: Nocturnal muscle cramps are sudden, involuntary, painful muscle contractions that occur in the night and are accompanied by hardening of the muscles. Many symptomatic treatments have been introduced for nocturnal muscle cramps, such as quinine, magnesium, and phenytoin. However, the efficacy and safety of these drugs have not been adequately evaluated. To demonstrate the efficacy and safety of phenytoin treatment for nocturnal muscle cramps, we conducted a retrospective study of 16 patients with nocturnal muscle cramps. METHODS: We reviewed 16 patients (6 men, 10 women) who suffered frequent nocturnal muscle cramps and were treated with phenytoin. The patients' clinical information (age, sex, disease duration, and locations of cramps), treatment dosage, and frequency of cramps were obtained by reviewing their medical records. RESULTS: The patients were aged 63.1+/-14.7 years (mean+/-SD; age range, 30-80 years; median age, 68 years). Twelve and four patients received phenytoin doses of 100 and 200 mg/day, respectively. The median duration of medication was 51 days (range, 14-378 days). Phenytoin treatment was effective in all patients; 13 patients (81.3%) experienced a total remission of their symptoms, and a significant reduction (66.7-85.7%) in the frequency of cramps was found in the remaining 3 patients. No adverse effects were reported by any of the patients. CONCLUSIONS: While this retrospective study was conducted with only a small number of patients, the clinical results suggest that phenytoin is a safe and helpful therapy for the treatment of nocturnal muscle cramps.
