Myasthenia gravis steroid therapy

Among 79 patients who underwent thymectomy at the Mayo Clinic between 1982 and 1985, 55 had myasthenia gravis. Forty-one of these underwent resection through a partial sternotomy, and a full sternotomy was performed in the remaining 14 patients. There was no operative mortality and 96% of patients were extubated in recovery room. Only one patient required reintubation. Complications occurred in four patients (7%) and included respiratory failure, atelectasis requiring bronchoscopy, removal of a retained drain, and chylothorax. The mean length of the hospital stay was days but is shorter today.

After oral administration, ciprofloxacin is widely distributed throughout the body. Tissue concentrations often exceed serum concentrations in both men and women, particularly in genital tissue including the prostate. Ciprofloxacin is present in active form in the saliva, nasal and bronchial secretions, mucosa of the sinuses, sputum, skin blister fluid, lymph, peritoneal fluid, bile, and prostatic secretions. Ciprofloxacin has also been detected in lung, skin, fat, muscle, cartilage, and bone. The drug diffuses into the cerebrospinal fluid (CSF); however, CSF concentrations are generally less than 10% of peak serum concentrations. Low levels of the drug have been detected in the aqueous and vitreous humors of the eye.

Acetylcholinesterase inhibitors can provide symptomatic benefit and may not fully remove a person's weakness from MG. [46] While they might not fully remove all symptoms of MG, they still may allow a person the ability to perform normal daily activities. [46] Usually, acetylcholinesterase inhibitors are started at a low dose and increased until the desired result is achieved. If taken 30 minutes before a meal, symptoms will be mild during eating, which is helpful for those who have difficulty swallowing due to their illness. Another medication used for MG, atropine , can reduce the muscarinic side effects of acetylcholinesterase inhibitors. [47] Pyridostigmine is a relatively long-acting drug (when compared to other cholinergic agonists), with a half-life around four hours with relatively few side effects. [48] Generally, it is discontinued in those who are being mechanically ventilated as it is known to increase the amount of salivary secretions. [48] A few high-quality studies have directly compared cholinesterase inhibitors with other treatments (or placebo); their practical benefit may be such that it would be difficult to conduct studies in which they would be withheld from some people. [49] The steroid prednisone might also be used to achieve a better result, but it can lead to the worsening of symptoms for 14 days and takes 6–8 weeks to achieve its maximal effectiveness. [48] Due to the myriad symptoms that steroid treatments can cause, it is not the preferred method of treatment. [48] Other immune suppressing medications may also be used including rituximab . [50]
