The prevalence of myasthenia gravis (MG) in the counties of Hordaland and Sogn & Fjordane on January 1, 1984 was 9.6 per 100,000 inhabitants. Other autoimmune diseases were found in 11 out of 48 MG patients. The occurrence of autoimmune thyroiditis (5 patients, 10.4%) and systemic lupus erythematosus (4 patients, 8.3%) in the MG patients was clearly higher than that reported in the general population. Rheumatoid arthritis was found in 2 patients (4.2%). The autoimmune diseases were mainly recorded among the nonthymectomized MG patients. In addition to those with definite diseases of autoimmune nature, 3 other MG patients had thyroid antibodies and 1 had antinuclear factor without clinical evidence of autoimmune disease. Seven MG patients (14.6%) had unspecific arthralgia during active periods of MG. Two MG patients had ankylosing spondylitis.
1984年1月1日，霍达兰郡和松恩-菲尤拉讷郡重症肌无力（MG）的患病率为每10万居民中有9.6人。48例MG患者中有11例患有其他自身免疫性疾病。MG患者中自身免疫性甲状腺炎（5例，10.4%）和系统性红斑狼疮（4例，8.3%）的发生率明显高于普通人群报告的发生率。2例患者（4.2%）患有类风湿性关节炎。自身免疫性疾病主要记录在未行胸腺切除术的MG患者中。除了那些患有明确自身免疫性疾病的患者外，另外3例MG患者有甲状腺抗体，1例有抗核因子，但无自身免疫性疾病的临床证据。7例MG患者（14.6%）在MG活动期有非特异性关节痛。2例MG患者患有强直性脊柱炎。
