A clinical case of the development of the Waterhouse-Friderichsen syndrome after SARS-CoV-2 infection in a patient with secondary AA - adrenal amyloidosis is presented. Description of the case. Patient G.G., 57 years old, was hospitalized for several hours on May 20, 2023 at the Cheboksary Regional Hospital with a diagnosis of severe viral interstitial pneumonia. Secondary AA adrenal amyloidosis. Acute adrenal insufficiency. She was admitted with complaints of an increase in body temperature up to 38.20C. Computed tomography of the chest organs showed signs of bilateral viral interstitial pneumonia (the percentage of lung damage was 74%). The diagnosis of COVID-19 was based on a positive PCR test in nasopharyngeal swabs. Blood pressure - 80 / 40 mm Hg. Art. D - dimer - 786 ng / ml (not higher - 243 ng / ml). Despite treatment, the patient died. At autopsy in the lungs, dystelectasis, hyaline membranes, intraalveolar edema. In the adrenal glands - the deposition of amyloid masses, foci of necrosis of the cortical layer and hemorrhage. Signs of DIC - syndrome. Conclusion. The peculiarity of the case is the development of the Waterhouse-Frideriksen syndrome without signs of sepsis.","PeriodicalId":34156,"journal":{"name":"Klinicheskaia praktika","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135689850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease is characterized by variable muscle weakness of the proximal limbs, mainly the gluteal and femoral muscles, ptosis of the eyelids, diplopia, dysarthria and peripheral paresthesia, and decreased tendon reflexes. The peculiarity of the Lambert-Eaton myasthenic syndrome is manifested in a combination of increased muscle weakness and fatigue with the phenomenon of \"working in\" - an increase in muscle strength against the background of muscle load after a short-term maximum contraction. At the same time, the patient shows normal response of tendon reflexes. Myasthenic Lambert-Eaton syndrome is often associated with small cell lung cancer and very rarely develops with tumors of other localization.
 We observed an 80-year-old patient with complaints of weakness and pain in the hips, shoulders, pelvic region, half-ptosis of the eyelids. For half-ptosis of the eyelids, a differential diagnosis was made with myasthenia gravis. Stimulation electromyography revealed the M-response increment, i.e. the phenomenon of working in, which is typical for this syndrome. The examination revealed papillary thyroid cancer, which later was undergoing surgical treatment.
 This case illustrates Lambert-Eaton's paraneoplastic myasthenic syndrome, a rare tumor form associated with thyroid cancer.
