OBJECTIVE: To investigate the clinical characteristics of overlapping syndromes of low muscle mass in Chinese patients with rheumatoid arthritis (RA) and their impact on physical function. METHODS: Consecutive patients with RA were recruited from September 2019 to April 2024 at Department of Rheumatology and Immunology, Sun Yat-Sen Memorial Hospital. Clinical data including disease acti-vity, physical function and radiographic assessment were collected. All patients also finished measurement of body composition, grip strength, and gait speed, and overlapping syndromes of low muscle mass as well as malnutrition, sarcopenia, sarcopenic obesity, and cachexia were evaluated. The Stanford health assessment questionnaire- disability index (HAQ-DI) was used to evaluate physical function. Logistic regression was used to analyze the related factors of physical dysfunction. RESULTS: A total of 1 016 RA patients were recruited. Their mean age was (52.4±12.5) years, and 82.5% were female. There were 557 cases (54.8%) with overlapping syndromes of low muscle mass and all of them were malnutrition. On this basis, 326 cases (32.1%) exhibited sarcopenia, 124 (12.2%) sarcopenic obesity, and 33 (3.2%) cachexia. There were 584 (57.4%) of RA patients having physical dysfunction, with varying degrees of severity 421 (41.4%) mild, 124 (12.2%) moderate, and 39 (3.8%) severe. Compared with patients without overlapping syndromes of low muscle mass (n=459) or with malnutrition only (n=231), RA patients with both malnutrition and sarcopenia (n=326) had significantly higher core disease activity indicators and higher rate of physical dysfunction (69.6% vs. 42.0% vs. 56.6%). However, compared with patients without overlapping syndromes of low muscle mass, patients with malnutrition only had lower HAQ-DI score (median 0.0 vs. 0.1) and lower rate of physical dysfunction (42.0% vs. 56.6%). Multivariate Logistic regression analysis showed that simultaneously overlapping malnutrition and sarcopenia were associated factors of physical dysfunction (OR=2.021, 95%CI: 1.067-3.828), but malnutrition only was not. CONCLUSION Simultaneously overlapping malnutrition and sarcopenia can deteriorate disease activity and physical dysfunction in RA patients. The screening and evaluation of overlapping syndromes of low muscle mass, especially sarcopenia should be emphasized in patients with RA.

The most common finding related to nonalcoholic steatohepatitis is obesity, but a status of severe malnutrition can also induce the steatohepatitis. The authors report a rare case of steatohepatitis leading to hepatic decompensation caused by malnutrition after pancreaticoduodenectomy. A 68-year-old female patient who had been previously diagnosed with pancreatic cancer and had undergone pancreaticoduodenectomy 5 months previously presented with abdominal distension. Routine CT performed 3 months after the surgery revealed severe fatty liver without evidence of tumor recurrence. After undergoing pancreaticoduodenectomy her food intake had reduced, and as a result she had lost 7 kg of body weight over 2 months. At this admission, CT revealed moderate amounts of ascites without tumor recurrence. Furthermore, her albumin and lipid profile levels were markedly decreased, and she had a flapping tremor and slurred speech suggestive of hepatic encephalopathy. Her liver biopsy findings were consistent with steatohepatitis and disclosed macrovesicular steatosis without definite fibrosis. After careful nutritional control, her symptoms disappeared and her laboratory findings improved.

OBJECTIVETo enhance our understanding of pediatric Crohn's disease and improve diagnostic accuracy and therapeutic efficacy by characterizing the clinical picture and reviewing 10 years' clinical experience in diagnosis and treatment.

METHODSNine cases with active Crohn's disease diagnosed between 1996 and 2005, including 8 males and 1 female, aged 6 - 13 years, were reviewed. Clinical, radiologic, endoscopic and histological data as well as therapeutic results were analized.

RESULTSThe mean interval from the onset of symptoms to the diagnosis was 10 months. The sites of involvement were both the small intestine and colon in 6, small intestine only in 3. Abdominal pain and diarrhea were the two most common gastrointestinal symptoms. The main extraintestinal manifestations were weight loss in 7, hypoalbuminemia in 5, mild anemia in 5, fever in 4 and hypocalcemia in 2. All the patients had undergone colonoscopy, and the findings included ulcerations, segmental lesions, cobblestone appearance, pseudopolyps and perianal abnormalities. Capsule endoscopic examination in one patient demonstrated the segmental distribution with typical longitudinal cleft-like ulcers and cobblestone appearance. Gastrointestinal barium meal X-ray examination was performed in 7 patients, the main findings were segmental strictures and abnormal mucosa. Histological examination of biopsy specimens mainly showed nonspecific chronic inflammation. Non-caseating granulomas were identifiable in 2 cases. Although there were many macroscopic and microscopic features supporting the diagnosis of Crohn's disease, no epithelioid granuloma could be found in surgical specimens of two patients. Treatment was given up by parents of 2 patients after the diagnosis was established. All the other 7 patients were treated with 5-acetylsalicylic acid, antibiotics and nutritional support during the acute phase. Corticosteroids were used in two patients. Long-term remission was achieved and maintained in 3 children, and in one of them medication could be discontinued and had no signs of disease activity at the end of the follow-up.

CONCLUSIONSChildren and adolescents presenting with Crohn's disease commonly have weight loss and nutritional impairment, which may provide clues to the diagnosis. Appropriate formulation and higher dosage of 5-acetylsalicylic acid [30-50 mg/(kg x d)] may be effective in inducing and maintaining remission in pediatric Crohn's disease.

We present here a case of acrodermatitis enteropathica-like eruption associated with essential free fatty acid and protein deficiencies as well as borderline zinc deficiency that occurred after Whipple's operation in a 31-yr-old woman. Her eruptions were improved not by zinc supplements alone, but her condition was improved by total parenteral nutrition including amino acids, albumin, lipid and zinc. Although we could not exactly decide which of the nutrients contributed the most to her manifestations, we inferred that all three elements in concert caused her dermatoses. This case shows that even though the patient's skin manifestations and laboratory results are suggestive of acrodermatitis enteropathica, the physicians should keep in mind the possibility that this disease can be associated with other nutritional deficiencies such as free fatty acid or protein deficiency.
