Higher body mass index is associated with lower foot health in patients with rheumatoid arthritis: baseline results of the Amsterdam-Foot cohort.

Objective: Obesity is highly prevalent in patients with rheumatoid arthritis (RA), with likely impact on weight-bearing foot joints. We explored the associations between body mass index (BMI) and measures of foot health in patients with RA and foot complaints.Method: We examined patients with RA presenting for their first custom-made therapeutic footwear or foot orthoses. Domains of foot health comprised: foot pain, foot-related activity limitations, forefoot plantar pressure, foot synovitis, and foot deformity. In regression analyses, BMI was the independent variable and foot health domains were the dependent variables.Results: The cohort at baseline comprised 230 patients [mean ± sd age 58 ± 13 years, 80% female, mean ± sd disease duration 10 ± 9 years, and median (interquartile range) BMI 26.7 (23.5-30.1) kg/m2]. Small to modest statistically significant associations were found in the majority of the measures studied between a higher BMI and more foot pain, more foot-related activity limitations, higher in-shoe measured forefoot plantar pressure, and the presence of foot synovitis. No relationships were found between BMI and barefoot measured forefoot plantar pressure or foot deformity.Conclusion: BMI is negatively associated with foot health in patients with RA. Although the clinical relevance of our findings for an individual patient is not immediately obvious, future research should consider BMI as a potential therapeutic target to improve foot health.

[Cholestatic hepatitis ascribed to the use of thiabendazole]. / Cholestatische hepatitis toegeschreven aan het gebruik van tiabendazol.

Two women, aged 27 and 42 years, both born in Surinam and both suffering from heterozygous thalassemia, developed cholestatic hepatitis three and two weeks respectively after the start of a two-day course of thiabendazol for Strongyloides stercoralis infection. Other causes of cholestasis were unlikely in view of the results of blood tests, echography and the endoscopic retrograde cholangiopancreaticography. The symptoms persisted for several months, and the liver function disorders for 7 years and one year, respectively. The incidence of thiabendazole-induced cholestatic hepatitis is unknown, but probably low.

[Liver damage attributed to the use of disulfiram]. / Leverbeschadiging toegeschreven aan het gebruik van disulfiram.

In three alcoholic patients, two men aged 30 and 42, and a woman aged 52, hepatitis was diagnosed after the use of disulfiram. In all cases, there was a close temporal relationship between the occurrence of symptoms and disulfiram intake. Other possible causes were excluded. The 30-year-old man died from liver damage. Biopsy showed massive hepatic necrosis without signs of alcoholic hepatitis. In the other patients, symptoms subsided quickly and liver function returned to normal after discontinuation of disulfiram, but there was no confirmation by biopsy. The possibility of drug-induced hepatitis should always be considered in an alcoholic patient treated with disulfiram.

[Respiratory insufficiency due to pulmonary toxicity of amiodarone]. / Respiratoire insufficiëntie door pulmonale toxiciteit van amiodaron.

A 70-year-old woman suffering from atrial fibrillation was treated with amiodarone, but developed acute respiratory failure necessitating mechanical ventilation for four weeks. Pulmonary function remained restrictively impaired after weaning from the ventilation, due to pulmonary fibrosis. Pulmonary toxicity is a well-known adverse reaction to amiodarone, but it rarely requires mechanical ventilation. The Netherlands Centre for Monitoring of Adverse Reactions to Drugs received II reports of this life-threatening reaction since 1976.
