- Comparison of body fat content and distribution of familial amyloidotic polyneuropathy patients versus healthy subjectsPublication . Pimenta, Nuno; Santa-Clara, Helena; Tomás, Maria Teresa; Monteiro, Estela; Cabri, Jan; Freire, António; Barroso, Eduardo; Sardinha, Luís; Fernhall, BoThe deposition of amyloid fibers at the peripheral nervous system can induce motor neuropathy in Familial Amiloidotic Polyneuropethy (FAP) patients. This produces progressive reductions in functional capacity. The only treatment for FAP is a liver transplant, followed by aggressive medication that can affect patients' metabolism. To our knowledge, there are no data on body fat distribution or comparison between healthy and FAP subjects, which may be important for clinical assessment and management of this disease. PURPOSE: To analyze body fat content and distribution between FAP patients and healthy subjects. METHODS: Body fat content and distribution were measured through Double Energy X-ray Densitometry (DXA) in two groups. Group 1 consisted of 43 Familial Amyloidotic Polyneuropathy patients (19 males, 32 + 8 Yrs, and 24 females, 37 + 5 yrs), who had liver transplant less than 2 months before. Group 2 consisted of 18 healthy subjects of similar age (8 males, 36 + 7 yrs, and 10 females, 39 + 5 yrs). RESULTS: Healthy subjects showed higher values than FAP patients for: BMI (24,2+2,3kg/m2 vs 22,3+3,8 kg/m2 respectively, p<0,05), % trunk BF (26,21+8,34kg vs 20,78+9,05kg respectively, p<0,05), % visceral BF (24,43+7,97% vs 19,21+9,30% respectively, p<0,05), % abdominal BF (26,63+8,51% vs 20,63+10,35% respectively, p<0,05) abdominal subcutaneous BF (0,533+0,421kg vs 0,353+0,257kg respectively, p=0,05), abdominal BF/BF ratio (0,09+0,02 vs 0,08+0,02 respectively, p<0,05) and abdominal BF/trunk BF ratio (0,19+0,03 vs 0,17+0,03 respectively, p<0,05). CONCLUSIONS: These results showed that FAP patients soon after liver transplantation exhibited a healthier body fat profile compared to controls. However, fat content and distribution varied widely in FAP subjects, suggesting an individualized approach for assessment and intervention rather than general guidelines. Future research is needed to investigate the long term consequences on body fat following liver transplant in this population.

- Peak force in familial amyloidotic polyneuropathyPublication . Tomás, Maria Teresa; Santa-Clara, Helena; Monteiro, Estela; Cabri, Jan; Freire, António; Barroso, EduardoFamilial Amyloidotic Polyneuropathy FAP)- A neurodegenerative disease related with systemic deposition of amyloid fibers mainly at the level of the peripheral nervous system. Clinically, the disease is characterized by an autonomous sensitive-motor neuropathy, beginning nearly always in foot, and subsequently involving the hands. Purpose: Compare the levels of hand grip strength (peak force) in FAP patients with (FAPT) or without (FAPNT) liver transplant and in a healthy group (HG).
- Strength, muscle quality and functional capacity in liver transplanted familial amyloidotic polineuropathy patientsPublication . Tomás, Maria Teresa; Santa-Clara, Helena; Monteiro, Estela; Pimenta, Nuno; Cabri, Jan; Freire, António; Barroso, EduardoLiver transplantation is the unique treatment for several end-stage diseases. Familial Amiloidotic Polineuropathy (FAP) is a neurodegenerative disease related with systemic deposition of amyloidal fiber mainly on peripheral nervous system, clinically translated by an autonomous sensitive-motor neuropathy with severe functional limitations in some cases. The unique treatment for FAP disease is a liver transplant with a very aggressive medication to muscle metabolism and force production. To our knowledge there are no quantitative characterizations of body composition, strength or functional capacity in this population.

Tomás, Maria Teresa; Santa-Clara, Helena; Monteiro, Estela; Pimenta, N.; Cabri, Jan; Freire, António; Barroso, EduardoLiver transplantation is the unique treatment for several end stage diseases. Familial Amiloidotic Polineuropathy (FAP) is a neurodegenerative disease related with systemic deposition of amyloidal fibre mainly on peripheral nervous system, clinically translated by an autonomous sensitive-motor neuropathy with severe functional limitations in some cases. The unique treatment for FAP disease is a liver transplant with a very aggressive medication to muscle metabolism and force production. To our knowledge there are no quantitative characterizations of body composition, strength or functional capacity in this population. The purpose of this study was to compare levels of specific strength (isometric strength adjusted by lean mass or muscle quality) and functional capacity (meters in 6 minutes walk test) between FAP patients after a liver transplant (4.1±2 months after transplant surgery) (FAPT) and a healthy group (HG).
