Fjölónæmir berklar á Íslandi: tilfellaröð og yfirlit

Multidrug resistant tuberculosis (MDRTB) is a growing health problem in the world. Treatment outcomes are poorer, duration longer and costs higher. We report three cases of MDR-TB diagnosed in Iceland in a six year period, 2003-8. Case descriptions: The first case was a 23-year-old immigrant with a prior history of latent TB infection treated with isoniazid. He was admitted two years later with peritoneal MDR-TB. He was treated for 18 months and improved. The second case was a 23-year-old immigrant diagnosed with pulmonary MDR-TB after having dropped out of treatment in his country of origin. Clinical and microbiological response was achieved and two years of treatment were planned. The third case involved a 27- year-old asymptomatic woman diagnosed with MDR-TB on contact tracing, because of her brother's MDR-TB. 18 months of treatment were planned. Conclusions: Clustering of cases of MDR-TB in the last six years, accounting for almost 5% of all Icelandic TB cases in the period, suggests that an increase in incidence might be seen in Iceland in coming years. The infection poses a health risk to the patients and the general public as well as a financial burden on the health care system. Emphasis should be put on rapid diagnosis and correct treatment, together with appropriate immigration screening and contact tracing.
