The majority of neurologically symptomatic cerebrospinal fluid HIV-1 escape cases are connected with resistance-associated mutations and potentially explained by low cerebrospinal fluid antiretroviral concentrations. However, there are still significant knowledge gaps regarding the physiopathology and long-term management of neurosymptomatic viral escape. We report a case of Parkinson-like syndrome following cerebrospinal fluid HIV-1 escape in a 40-year-old female patient with an history of persistent low-level plasma viremia under treatment...

The characteristics of adult patients with chronic active Epstein-Barr virus infection (adult-onset CAEBV) are poorly recognized, hindering early diagnosis and an improved prognosis. Adult-onset CAEBV (n = 54) diagnosed between 2005 and 2015 were conducted. Adult-onset was defined as an estimated age of onset ≥15 years. To characterize the clinical features of adult-onset CAEBV, we compared them to those of pediatric-onset (estimated age of onset <15 years) patients (n = 75). We compared the prognosis of adult-onset CAEBV with that for patients with nasal-type (n = 37) and non-nasal-type (n = 45) extranodal NK/T-cell lymphoma (ENKTL)...

Weili Kong, Jian Zhu
Zika virus (ZIKV) is a mosquito-borne flavivirus that was relatively obscure until outbreaks started in 2013. ZIKV is associated with neurological manifestations such as Guillan-Barrè Syndrome in adult and microcephaly in the newborn population. Although the majority of disease mechanisms of ZIKV is unclear, some information was updated with new scientific evidence. Currently, there are no approved drugs or vaccine that can be used for therapy during ZIKV infection. Based on the transmission mechanism of ZIKV, vector control and safe sex seem to be the most effective available preventive measures against ZIKV spread...

BACKGROUND: In many countries, sexually transmitted infections (STIs) are treated syndromically. Thus, patients diagnosed as having genital ulcer disease (GUD) in Zimbabwe receive a combination of antimicrobials to treat syphilis, chancroid, lymphogranuloma venereum (LGV), and genital herpes. Periodic studies are necessary to assess the current etiology of GUD and assure the appropriateness of current treatment guidelines. MATERIALS AND METHODS: We selected 6 geographically diverse clinics in Zimbabwe serving high numbers of STI cases to enroll men and women with STI syndromes, including GUD...

INTRODUCTION: Sexually transmitted infections (STIs) are managed syndromically in most developing countries. In Zimbabwe, men presenting with urethral discharge are treated with a single intramuscular dose of kanamycin or ceftriaxone in combination with a week's course of oral doxycycline. This study was designed to assess the current etiology of urethral discharge and other STIs to inform current syndromic management regimens. METHODS: We conducted a study among 200 men with urethral discharge presenting at 6 regionally diverse STI clinics in Zimbabwe...

Guillain-Barré syndrome is a life-threatening neurological disorder that presents with rapid ascending paralysis and areflexia. Guillain-Barré syndrome is traditionally associated with infections from a gastrointestinal or respiratory tract source. We report the case of a 71-year-old man with melanoma who was treated with ipilimumab as adjuvant immunotherapy and subsequently developed Guillain-Barré syndrome. The diagnosis was made clinically through physical exam findings. He was successfully treated with a combination of intravenous immunoglobulin therapy and corticosteroids...

The ongoing Zika virus (ZIKV) outbreak in Latin America, the Caribbean, and the Pacific Islands has underlined the need for a coordinated research network across the whole region that can respond rapidly to address the current knowledge gaps in Zika and enhance research preparedness beyond Zika. The European Union under its Horizon 2020 Research and Innovation Programme awarded three research consortia to respond to this need. Here we present the ZikaPLAN (Zika Preparedness Latin American Network) consortium...

BACKGROUND: The late effects of treatment for acute lymphoblastic leukemia (ALL) include disordered body composition, especially obesity. Less attention has been focused on the loss of skeletal muscle mass (SMM) and the combined morbidity of sarcopenic obesity. METHODS: A cross-sectional study of body composition was undertaken via dual-energy x-ray absorptiometry in 75 long-term survivors of ALL (more than 10 years after the diagnosis). Measures were obtained of the fat mass (FM), fat-free mass (equivalent to the lean body mass [LBM]), and whole-body bone mineral content...

GABAergic and glutamatergic dysfunction in the dorsolateral prefrontal cortex (DLPFC) are thought to be the core pathophysiological mechanisms of schizophrenia. Recently, we have established a method to index these functions from the DLPFC using the paired transcranial magnetic stimulation (TMS) paradigms of short interval intracortical inhibition (SICI) and facilitation (ICF) combined with electroencephalography (EEG). In this study, we aimed to evaluate neurophysiological indicators related to GABAA and glutamate receptor-mediated functions respectively from the DLPFC in patients with schizophrenia using these paradigms, compared to healthy controls...

The recent outbreak of Zika virus (ZIKV), a re-emerging flavivirus, and its associated neurological disorders, such as Guillain-Barré (GB) syndrome and microcephaly, have generated an urgent need for developing effective ZIKV vaccines and therapeutic agents. Here, we used human endothelial cells and astrocytes, both of which represent key cell types for ZIKV infection, to identify potential inhibitors for ZIKV replication. Because several pathways, including AMP-activated protein kinase (AMPK), protein kinase A (PKA), and mitogen-activated protein kinase (MAPK) signaling pathways, have been reported to play important roles in flavivirus replication, we tested inhibitors or agonists of these pathways for their effects on ZIKV replication...

Fifty years after the discovery of Epstein-Barr virus (EBV), it remains unclear how primary infection with this virus leads to massive CD8 T-cell expansion and acute infectious mononucleosis (AIM) in young adults. AIM can vary greatly in severity, from a mild transient influenza-like illness to a prolonged severe syndrome. We questioned whether expansion of a unique HLA-A2.01-restricted, cross-reactive CD8 T-cell response between influenza virus A-M158 (IAV-M1) and EBV BMLF1280 (EBV-BM) could modulate the immune response to EBV and play a role in determining the severity of AIM in 32 college students...

Guillain-Barré Syndrome (GBS) is an inflammatory polyradiculoneuropathy which is known to produce syndrome of inappropriate Secretion of Antidiuretic Hormone (SIADH). However, the hyponatremia is usually seen after the onset of weakness. Here, we report a case of SIADH that presented with hyponatremic seizures which preceded the onset of GBS by ten days.

Guillain-Barre Syndrome is very rare in parasitic and rickettsial infection. Here we report a case of Plasmodium falciparum and scrub typhus mixed infection, presented with quadriparesis. Clinical, Serological, CSF analysis and Nerve Conduction Studies were consistent with Acute Inflammatory Demyelinating Polyneuropathy (variant of GBS). After administration of antimalarials and antibiotics for the mixed infection, patient gradually improved.

ANX005 is a humanized immunoglobulin G4 recombinant antibody against C1q that inhibits its function as the initiating molecule of the classical complement cascade. The safety and tolerability of ANX005 are currently being evaluated in a phase I trial in healthy volunteers ( www.clinicaltrials.gov Identifier: NCT03010046). Inhibition of C1q can be applied therapeutically in a broad spectrum of diseases, including acute antibody-mediated autoimmune disease, such as Guillain-Barré syndrome (GBS), and in chronic diseases of the central nervous system involving complement-mediated neurodegeneration, such as Alzheimer's disease (AD)...

Microbial infections lead to neurological damages either by direct infection in the nervous tissues or by uncontrolled immune responses (immunopathology). For example, in Zika virus infection, microcephaly can be caused by the former, i.e., direct viral infection in the brain, while Guillain-Barré syndrome (GBS) seems to be antibody-mediated immunopathology. Although a variety of factors affect immunopathology, two essential systems maintaining whole-body homeostasis had long been neglected: 1) the lymphatic system and 2) microbiota...

BACKGROUND: Guillain-Barré Syndrome (GBS) is a severe paralytic neuropathy associated with virus infections such as Zika virus and Chikungunya virus. There were also case reports of dengue fever preceding GBS. With the aim to understand the mechanisms of GBS and dengue outbreaks, this ecological study investigates the relationships between GBS, dengue, meteorological factors in Hong Kong and global climatic factors from January 2000 to June 2016. METHODS: The correlations between GBS, dengue, Multivariate El Niño Southern Oscillation Index (MEI) and local meteorological data were explored by Spearman's Rank correlations and cross-correlations...

Acute chest syndrome (ACS) is a common and serious lung complication in sickle cell disease. A retrospective medical chart review was performed over a 6-year period in all pediatric ACS patients to investigate whether factors during the initial hospitalization were associated with recurrent ACS episodes. There were 386 episodes of ACS: 149 had only 1 episode of ACS, and 76 had >1 episode of ACS; 172 (76.4%) had hemoglobin SS, and 39 (17.3%) had hemoglobin SC. The most common presenting features were fever (83%), pain (70%), and cough (61%), which changed with the number of ACS episodes...

A 62-year-old woman with rheumatoid arthritis and secondary Sjögren's syndrome took methotrexate (MTX) 5 mg three times a week regularly but gradually developed an intermittent fever, oral ulcers and productive cough with mucopurulent sputum for about 2 weeks. Image study found multiple nodular lesions and lymphadenopathies in bilateral lungs. Empirical antibiotics for 1 week failed to alleviate the fever. A transbronchial biopsy in the right fourth bronchus showed infiltration of abnormally enlarged lymphoid cells with a surface marker of CD20, some of which also stained positively in situ with Epstein-Barr virus-encoded small RNA and some CD3(+) cells...
