3 cases of Werner's syndrome were studied on serum lipid metabolism in comparison with clinical manifestation. These 3 cases showed hyperlipemia all with hypertriglycemia and increased level of very low density lipoprotein. The lipoprotein lipase activity was shown after intravenous injection of heparin. These results indicate a possible pathogenic facet of Werner's syndrome from the lipid metabolic point of view.

To assess the risk factors for atherosclerosis in Werner's syndrome (WS), coagulation/fibrinolytic system parameters and lipid levels were investigated in 9 non-smoker patients with WS and compared with normal control values (N). The levels of thrombin antithrombin III complex (p < 0.05), D-dimer (p < 0.05), tissue plasminogen activator (p < 0.005) and PA inhibitor 1 (p < 0.01) were significantly increased, while the level of thrombomodulin (p < 0.005) in the fasting plasma was significantly decreased in the WS cases compared with N. Lipid profiles confirmed that 8 of the 9 patients were of hyperlipidemia type IIb, 7 had hyperinsulinemia and 5 fulfilled the criteria for clinical diabetes mellitus. The hypercoagulable condition suggested the existence of multiple risk factors for atherosclerosis in WS in addition to the previously reported hyperinsulinemia and hyperlipidemia.

Werner syndrome is a rare premature aging syndrome accompanied by severe atherosclerosis. The etiology of atherosclerosis is suspected to be due to its complications, namely diabetes mellitus, hyperinsulinemia and hyperlipidemia. But from an autopsy case we found that some other risk factors may be involved in the mechanism of atherosclerosis in this syndrome. Previously we revealed that the plasminogen activator inhibitor-1 (PAI-1) gene was being overexpressed in skin fibroblasts from a patient with this syndrome. PAI-1 is a potent inhibitor of tissue plasminogen activator and a possible risk factor of atherosclerosis. This led us to assess the plasma concentration of PAI-1. Our working hypothesis was that the PAI-1 gene was upregulated or not fully suppressed in cells responsible for the production of PAI-1 in plasma as well as in fibroblasts. The results show a high concentration of plasma PAI-1. One of the well-known physiological substances that induce the PAI-1 gene is tumor necrosis factor-alpha, which also induces other possible risk factors of atherosclerosis, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1. We found the serum concentrations of ICAM-1 to be elevated in patients with this syndrome. We conclude that high concentrations of PAI-1 and ICAM-1 in blood may be one of the potent causes of severe atherosclerosis in Werner syndrome.

We described a case of Werner's syndrome associated with osteosarcoma. A 37-year-old Japanese man was diagnosed as having Werner's syndrome by the presence of juvenile cataracts, skin sclerosis and hyperpigmentation of the feet, high-pitched voice, characteristic bird-like appearance of the face with beak-shaped nose, thinning of the entire skin and hyperkeratoses on soles, hyperlipemia, hyperuricemia, diabetes melitus, and the mutated responsible gene (WRN). He had a 3-month history of a tumor on his left forearm. Histologically, the tumor included four histological patterns; a malignant fibrous histiocytoma-like, a desmoid-like, a dermatofibrosarcoma protuberans-like, and a chondrosarcoma-like pattern. Tumoral osteoid formation was also found in the tumor. Therefore, the tumor was diagnosed as osteosarcoma.

Werner's syndrome (WS), a representative progeroid syndrome with chromosomal instability caused by the mutation of RecQ type DNA/RNA helicase, manifests skin changes similar to those observed in systemic sclerosis (SSc). In addition, patients with WS show a variety of the signs and symptoms of normal ageing at an early stage of their life; gray hair, alopecia, muscle atrophy, osteoporosis, cataracts, hypogonadism, diabetes mellitus, hyperlipidemia, atherosclerosis, malignancy, brain atrophy, and senile dementia. Although no direct evidence has been presented linking RecQ type DNA/RNA helicase dysfunction with the occurrence of premature ageing symptoms in WS, WS may give us a unique model to analyze the skin changes and the mechanisms of fibrosis in SSc.

A 54-year-old man was found to have hypertension at age 32, and a diagnosis of Werner's Syndrome was made at age 36 when he was examined for hyperlipidemia. Diabetes mellitus was found at age 42. Proteinuria appeared at age 49, and microscopic hematuria was seen at age 50. At age 51, serum creatinin level began to rise and atrophy of bilateral kidneys was observed by abdominal CT. There after, the renal function gradually worsened. At age 53, the serum creatinin level rose to 8.3 mg/dl, and systemic edema as well as loss of appetite appeared, resulting in the initiation of hemodialysis. In Werner's syndrome, though arteriosclerosis arises frequently, case reports with chronic renal failure are extremely rare. To investigate the cause of the renal dysfunction, renal biopsy was performed and the samples were histologically examined, revealing the presence of hypertensive glomerular changes. It is, thus, conceivable that hypertension had played a major role in the progression of renal failure in this case.

Non-alcoholic steatohepatitis (NASH) is characterised by steatosis, liver cell injuries, the presence of a mixed inflammatory lobular infiltrate, and variable degrees of fibrosis. Werner syndrome (WS) is a rare autosomal recessive disease characterised by the premature onset of multiple age-related disorders. Central obesity and insulin resistance are common symptoms of both NASH and WS. Three cases were studied to evaluate the association between WS and NASH. NASH was diagnosed by liver biopsies and imaging studies following the exclusion of alcohol consumption, viral disease or autoimmune liver disease. Liver histology was compatible with NASH in all cases. Liver dysfunction, hyperlipidaemia, insulin resistance and regional increase of intra-abdominal fat even though the body mass indices were all normal or low, were observed. Metabolic disorders due to WS may complicate and cause NASH. Hence, the observed clinical association between WS and NASH suggests that patients with WS should also be screened for NASH.

Werner syndrome (WS) is a rare, adult-onset progeroid syndrome. Classic WS is caused by WRN mutation and partial atypical WS (AWS) is caused by LMNA mutation. A 19-year-old female patient with irregular menstruation and hyperglycemia was admitted. Physical examination revealed characteristic faces of progeria, graying and thinning of the hair scalp, thinner and atrophic skin over the hands and feet, as well as lipoatrophy of the extremities, undeveloped breasts at Tanner stage 3, and short stature. The patient also suffered from severe insulin-resistant diabetes mellitus, hyperlipidemia, fatty liver, and polycystic ovarian morphology. Possible WS was considered and both WRN and LMNA genes were analyzed. A novel missense mutation p.L140Q (c.419T>A) in the LMNA gene was identified and confirmed the diagnosis of AWS. Her father was a carrier of the same mutation. We carried out therapy for lowering blood glucose and lipid and improving insulin resistance, et al. The fasting glucose, postprandial glucose and triglyceride level was improved after treatment for 9 days. Literature review of AWS was performed to identify characteristics of the disease. Diabetes mellitus is one of the clinical manifestations of WS and attention must give to the differential diagnosis. Gene analysis is critical in the diagnosis of WS. According to the literature, classic and atypical WS differ in incidence, pathogenic gene, and clinical manifestations. Characteristic dermatological pathology may be significantly more important for the initial identification of AWS. Early detection, appropriate treatments, and regular follow-up may improve prognosis and survival of WS patients.

Werner syndrome, also called adult progeria, is a heritable autosomal recessive human disorder characterized by the premature onset of numerous age-related diseases including juvenile cataracts, dyslipidemia, diabetes mellitus (DM), osteoporosis, atherosclerosis, and cancer. Werner syndrome is a segmental progeroid syndrome whose presentation resembles accelerated aging. The most common causes of death for WS patients are atherosclerosis and cancer. A 40-year-old female presented with short stature, bird-like facies, canities with alopecia, scleroderma-like skin changes, and non-healing foot ulcers. The patient reported a history of delayed puberty, abortion, hypertriglyceridemia, and juvenile cataracts. A clinical diagnosis of WS was made and subsequently confirmed. We discovered two WRN gene mutations in the patient, Variant 1 was the most common WRN mutation, nonsense mutation (c.1105C>T:p.R369Ter) in exon 9, which caused a premature termination codon (PTC) at position 369. Variant 2 was a frameshift mutation (c.1134delA:p.E379KfsTer5) in exon 9, which caused a PTC at position 383 and has no published reports describing. Patients with WS can show a wide variety of clinical and biological manifestations in endocrine-metabolic systems (DM, thyroid dysfunction, and hyperlipidemia). Doctors must be cognizant of early manifestations of WS and treatment options.
