Linezolid is one of the most effective drugs for treating multidrug-resistant tuberculosis (MDR TB), but adverse effects remain problematic. We evaluated 57 MDR TB patients who had received > 1 dose of linezolid during 2011–2016. Overall, patients received 600 mg/day of linezolid for a median of 13 months. In 33 (58%) patients, neurologic or ophthalmologic signs developed, and 18 (32%) had confirmed peripheral neuropathy, which for 78% was irreversible at 12 months after the end of TB treatment despite linezolid withdrawal. Among the 19 patients who underwent ophthalmologic evaluation, 14 patients had optic neuropathy that fully reversed for 2. A total of 16 (33%) of 49 patients had a linezolid trough concentration >2 mg/L, and among these, 14 (88%) experienced adverse effects. No significant association was found between trough concentration and neurologic toxicity. These findings suggest the need to closely monitor patients for neurologic signs and discuss optimal duration of linezolid treatment.

This pilot study suggests the efficacy of anakinra in patients with refractory scleritis.

Fluorescein angiography is the gold standard to describe Takayasu retinopathy ischemic signs. Macular abnormalities are uncommon in Takayasu patients as retinopathy signs are mostly located in peripheral retina. This study reveals that most of our patients present an enlargement of the FAZ then highlights the relevance of OCTA to evaluate macular ischemia as a complement to usual retina global study in fluorescein angiography.
