By the sixth month of treatment, 29 percent of patients treated with amikacin liposome inhalation suspension had no growth of mycobacteria in their sputum cultures for three consecutive months compared to 9 percent of patients who were not treated with amikacin liposome inhalation suspension.

Intrathecal baclofen administration may not have long-term benefits though, and there are potential serious side effects.Treatments that target the autoimmune response are also used. Intravenous immunoglobin is the best second-line treatment for SPS. It often decreases stiffness and improves quality of life and startle reflex. It is generally safe, but there are possible serious side effects and it is expensive. The European Federation of Neurological Societies suggests it be used when disabled patients do not respond well to diazepam and baclofen. Steroids, rituximab, and plasma exchange have been used to suppress the immune system in SPS patients, but the efficacy of these treatments is unclear. Botulinum toxin has been used to treat SPS, but it does not appear to have long-term benefits and has potential serious side effects. In paraneoplastic cases, tumors must be managed for the condition to be contained. Opiates are sometimes used to treat severe pain, but in some cases they exacerbate symptoms.Hematopoietic stem cell transplantation (HSCT) with high intensity conditioning protocol has been performed in a few cases with severe anti-GAD positive SPS, resulting in clinical remission. In carefully selected cases of severe, treatment refractory SPS, HSCT may be an effective therapeutic option. Prognosis
The progression of SPS depends on whether it is a typical or abnormal form of the condition and the presence of comorbidities. Early recognition and neurological treatment can limit its progression. SPS is generally responsive to treatment, but the condition usually progresses and stabilizes periodically. Even with treatment, quality of life generally declines as stiffness precludes many activities.
