METHODS:Sixteen patients with refractory GERC were given an 8-wk course of baclofen 20 mg three times a day as an add-on therapy to omeprazole. Changes in the cough symptom score, cough threshold to capsaicin, reflux symptom score and possible adverse effects were determined after treatment. The variables of multi-channel intraluminal impedance combined with pH monitoring were compared between responders and non-responders to baclofen. RESULTS:Twelve of 16 patients completed treatment. Cough disappeared or improved in 56.3% (9/16)of patients, including 6 patients with acid refluxinduced cough (66.7%) and 3 patients with non-acid reflux-induced cough (33.3%). With baclofen treatment, the cough symptom score began to decrease at week 2, was clearly decreased at week 6 and reached a minimum at week 8. At the end of therapy, the lowest concentration of capsaicin required for induction of ≥ 2 and ≥ 5 coughs increased from 0.98 (1.46) to 1.95 (6.82) μmol/L (Z = -2.281, P = 0.024) and from 1.95 (7.31) to 7.8 (13.65) μmol/L (Z = -2.433, P = 0.014), respectively, and the reflux symptom score decreased from 8.0 ± 1.6 to 6.8 ± 0.8 (t = 2.454, P = 0.023). The number of acid reflux episodes was significantly lower in responders than in non-responders. The main adverse effects were somnolence, dizziness and fatigue. CONCLUSION:Baclofen is a useful, but suboptimal treatment option for refractory GERC.展开更多

In recent years a significant amount of literature has helped focus on the details of treatment,and more data have accumulated regarding risks and benefits of pharmacologic treatment.In particular,the efficacy of pentoxifylline has become increasingly apparent,and when compared with the risks associated with prednisolone,has brought this drug to the forefront of therapy for severe AH.This review will focus on the clinical and laboratory diagnosis and pharmacologic therapies that should be applied during hospitalization and continued into outpatient management.We conclude that the routine use of glucocorticoids for severe AH poses significant risk with equivocal benefit,and that pentoxifylline is a better,safer and cheaper alternative.While the full details of nutritional support lie beyond the scope of this article,nutrition is a cornerstone of therapy and must be addressed in every patient diagnosed with AH. Finally,while traditional psychosocial techniques play a major role in post-hospitalization care of alcoholics, we hope to make the medical clinician realize his or her role in reducing recidivism rates with early and frequent outpatient visits and with the use of baclofen to reduce alcohol craving.展开更多
