Administration of N-acetylcysteine may be effective in diseases caused by oxidative-antioxidative imbalance. We aimed to determine the effect administration for 4 months of N-acetylcysteine (1200 mg daily) on sulfur mustard-induced bronchiolitis obliterans in patients with normal pulmonary function test. In a double-blind clinical trial, 144 patients with bronchiolitis obliterans due to sulfur mustard and bronchiolitis obliterans syndrome class 0, randomly entered to group 1 (n = 72, N-acetylcysteine) and group 2 (n = 72, placebo). The changes in dyspnoea, wake-up dyspnoea, cough and sputum were measured after 4 months using a 'delta value' (i.e. symptom score after 4 months--symptom score before the trial). Spirometric findings were measured at the beginning of the trial, 2 months later and 4 months later. Dyspnoea (delta value: -0.78 (0.61), P < 0.001), wake-up dyspnoea (delta value: -0.57 (0.64), P < 0.001), and cough (delta value: -0.86 (0.63), P < 0.001) improved after 4 months of N-acetylcysteine administration compared to the control group. N-acetylcysteine reduced sputum from 76.9% (n = 40) of cases before the trial to 9.6% (n = 5) of cases after the trial. Spirometric components were significantly improved in N-acetylcysteine group compared to the placebo group: FEV1 (P < 0.0001), FVC (P = 0.014) and FEV1/FVC (P = 0.003). A 4-month trial with 1200 mg oral N-acetylcysteine per day can be used for treating bronchitis, but is also effective in treating bronchiolitis. It also prevents sulfur mustard-induced oxidative stress, and can be used in the treatment of sulfur mustard-induced pulmonary disease.
给予N-乙酰半胱氨酸可能对由氧化-抗氧化失衡引起的疾病有效。我们旨在确定给予4个月的N-乙酰半胱氨酸(每日1200毫克)对肺功能测试正常的患者中硫芥诱导的闭塞性细支气管炎的影响。在一项双盲临床试验中,144例因硫芥导致闭塞性细支气管炎且为0级闭塞性细支气管炎综合征的患者,随机分为第1组(n = 72,N-乙酰半胱氨酸)和第2组(n = 72,安慰剂)。在4个月后使用“差值”(即4个月后的症状评分 - 试验前的症状评分)来测量呼吸困难、晨起呼吸困难、咳嗽和咳痰的变化。在试验开始时、2个月后和4个月后测量肺功能检查结果。与对照组相比,给予N-乙酰半胱氨酸4个月后,呼吸困难(差值:-0.78(0.61),P < 0.001)、晨起呼吸困难(差值:-0.57(0.64),P < 0.001)和咳嗽(差值:-0.86(0.63),P < 0.001)有所改善。N-乙酰半胱氨酸使试验前76.9%(n = 40)的病例咳痰减少至试验后的9.6%(n = 5)。与安慰剂组相比,N-乙酰半胱氨酸组的肺功能检查指标有显著改善:第1秒用力呼气容积(FEV1)(P < 0.0001)、用力肺活量(FVC)(P = 0.014)和FEV1/FVC(P = 0.003)。每日口服1200毫克N-乙酰半胱氨酸进行4个月的试验可用于治疗支气管炎,但对治疗闭塞性细支气管炎也有效。它还可预防硫芥诱导的氧化应激,并可用于治疗硫芥诱导的肺部疾病。
