RESUMO
BACKGROUND: Guillian--Barre' Syndrome (GBS) has been shown to be associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. The aim of our study was to study the clinical profile and outcomes of GBS in COVID-19 from the Western region of India, the State of Maharashtra. METHODS: This was a retrospective, multicenter observation study from different hospitals in Maharashtra beginning from March 2020 until November 2020. RESULTS: We report 42 patients with COVID-19 GBS. Mean age was 59 years (range, 24--85 years). 31/42 (73.8%) were men. GBS was the presenting symptom in 14/42 (33%), while six of them remained asymptomatic for COVID-19 despite positive SARS-CoV-2 on nasopharyngeal swab reverse transcriptase polymerase chain reaction. The median interval between COVID-19 and GBS was 14 days (SD + 11), with minimum of 1 and maximum 40 days. Clinical presentation was like that of typical GBS. Electrophysiological studies showed a predominant demyelinating pattern in 25/42 (59.5%). Inflammatory markers were elevated in 35/42 (83.3%) and 38/42 (90.5%) had an Abnormal high-resolution CT (HRCT) chest. 14/42 (33.3%) patients required a ventilator, with nine deaths. Intravenous immunoglobulin was the mainstay of treatment for GBS. Majority had a good outcome and were walking independently or with minimal support at discharge. In subgroup analysis, the postinfectious group had a better outcome than the parainfectious group. CONCLUSION: GBS in COVID-19 occurs as both parainfectious and postinfectious GBS. Parainfectious GBS needs more rigorous monitoring and may benefit from COVID-19 specific treatment. Routine screening for SARS-CoV-2 should be implemented in patients with GBS in view of the ongoing pandemic.
RESUMO
Idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of disorders that cause muscle weakness and also have extramuscular manifestations involving various organ systems; namely the lung, skin, heart, and joints. Previously classified broadly as dermatomyositis (DM) and polymyositis now the spectrum of the disease has evolved into more clinical subtypes. There are now five clinicoserological subtypes recognized worldwide DM, antisynthetase syndrome (AS), overlap myositis (OM), immune mediated necrotizing myopathy (IMNM), and inclusion body myositis. Each of these subtypes has a unique phenotype and specific antibodies associated. With the evolving treatment options from the use of immunosuppressive medications to the use of targeted therapy with biologic agents, and further understanding of the pathogenesis of inflammatory myositis, we may have more effective treatment options. We discuss in this review, various myositis-associated antibodies associated with each clinicoserological subtype of IIM and their role. We also describe the evolving therapies and the evidence for the newer biologic therapies in the treatment of IIMs.
RESUMO
We present a case of cerebral venous sinus thrombosis (CVST) as a rare complication of herpes simplex virus (HSV) encephalitis. A young man with no pertinent medical history was diagnosed with HSV encephalitis. After initial treatment, he showed improvement in symptomatology until day 6 when he acutely developed new neurological deficits. An urgent MRI brain showed changes in left temporal lobe consistent with HSV encephalitis and lack of flow void in superior sagittal sinus. Subsequent magnetic resonance venography confirmed the diagnosis of superior sagittal sinus thrombosis along with thrombosis of bilateral frontoparietal cortical draining veins. Anticoagulation was immediately initiated and oral anticoagulation was continued for 1 year. He made complete recovery subsequently. Our case serves as a reminder for the treating clinicians to consider CVST in patients with HSV encephalitis who develop an unexpected new neurological deficits during early phase of appropriate treatment.
