Smit DP, Mathew DK, Khairallah M, Yeh S, Cunningham ET. A Review of Human Ocular RNA Virus Infections Excluding Coronavirus, Human T-Cell Lymphotropic Virus, and Arboviruses. Ocul Immunol Inflamm 2023; 31:1454-1460. [PMID: 37315305 DOI: 10.1080/09273948.2023.2220027] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 05/03/2023] [Accepted: 05/26/2023] [Indexed: 06/16/2023]
Abstract
We provide an updated review of pre-selected RNA viruses causing ocular inflammation in humans. RNA viruses such as coronaviruses and arboviruses are reviewed elsewhere. A Google Scholar search was conducted to identify recent publications on ocular inflammation caused by the RNA viruses specified here. Human RNA viruses target a wide range of ocular tissues from the anterior to the posterior. Influenza, measles and mumps cause anterior segment manifestations including conjunctivitis and keratitis, while retinitis and optic neuritis may be seen posteriorly. Newcastle disease and RSV cause conjunctivitis, whereas HIV causes characteristic anterior uveitis. Cataracts, microphthalmos, and iris abnormalities are common in congenital Rubella, while Rubella virus is associated with Fuchs uveitis syndrome. Newer technologies make it possible to detect more than one pathogen if present simultaneously. RNA viruses may produce significant ocular morbidity, and care should be taken to investigate ocular symptoms during disease outbreaks.

Endocrine Dysfunction in Children with Zika-Related Microcephaly Who Were Born during the 2015 Epidemic in the State of Pernambuco, Brazil. Viruses 2020; 13:v13010001.

Abstract
Congenital viral infections and the occurrence of septo-optic dysplasia, which is a combination of optic nerve hypoplasia, abnormal formation of structures along the midline of the brain, and pituitary hypofunction, support the biological plausibility of endocrine dysfunction in Zika-related microcephaly. In this case series we ascertained the presence and describe endocrine dysfunction in 30 children with severe Zika-related microcephaly from the MERG Pediatric Cohort, referred for endocrinological evaluation between February and August 2019. Of the 30 children, 97% had severe microcephaly. The average age at the endocrinological consultation was 41 months and 53% were female. The most frequently observed endocrine dysfunctions comprised short stature, hypothyroidism, obesity and variants early puberty. These dysfunctions occurred alone 57% or in combination 43%. We found optic nerve hypoplasia (6/21) and corpus callosum hypoplasia (20/21). Seizure crises were reported in 86% of the children. The most common-and clinically important-endocrine dysfunctions were pubertal dysfunctions, thyroid disease, growth impairment, and obesity. These dysfunctions require careful monitoring and signal the need for endocrinological evaluation in children with Zika-related microcephaly, in order to make early diagnoses and implement appropriate treatment when necessary.

Mawson AR, Croft AM. Rubella Virus Infection, the Congenital Rubella Syndrome, and the Link to Autism. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E3543. [PMID: 31546693 PMCID: PMC6801530 DOI: 10.3390/ijerph16193543] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Revised: 09/09/2019] [Accepted: 09/15/2019] [Indexed: 12/16/2022]
Abstract
Rubella is a systemic virus infection that is usually mild. It can, however, cause severe birth defects known as the congenital rubella syndrome (CRS) when infection occurs early in pregnancy. As many as 8%-13% of children with CRS developed autism during the rubella epidemic of the 1960s compared to the background rate of about 1 new case per 5000 children. Rubella infection and CRS are now rare in the U.S. and in Europe due to widespread vaccination. However, autism rates have risen dramatically in recent decades to about 3% of children today, with many cases appearing after a period of normal development ('regressive autism'). Evidence is reviewed here suggesting that the signs and symptoms of rubella may be due to alterations in the hepatic metabolism of vitamin A (retinoids), precipitated by the acute phase of the infection. The infection causes mild liver dysfunction and the spillage of stored vitamin A compounds into the circulation, resulting in an endogenous form of hypervitaminosis A. Given that vitamin A is a known teratogen, it is suggested that rubella infection occurring in the early weeks of pregnancy causes CRS through maternal liver dysfunction and exposure of the developing fetus to excessive vitamin A. On this view, the multiple manifestations of CRS and associated autism represent endogenous forms of hypervitaminosis A. It is further proposed that regressive autism results primarily from post-natal influences of a liver-damaging nature and exposure to excess vitamin A, inducing CRS-like features as a function of vitamin A toxicity, but without the associated dysmorphogenesis. A number of environmental factors are discussed that may plausibly be candidates for this role, and suggestions are offered for testing the model. The model also suggests a number of measures that may be effective both in reducing the risk of fetal CRS in women who acquire rubella in their first trimester and in reversing or minimizing regressive autism among children in whom the diagnosis is suspected or confirmed.

Abstract
In countries and regions with high vaccination coverage, several vaccine-preventable diseases have been resurged in recent years, such as measles, varicella, pertussis and mumps. Some studies have found that the clinical manifestation and epidemiological characteristics of these diseases were different from those in pre-vaccine era. This article reviewed the clinical and epidemiological features of vaccine-preventable diseases before and after wide immunization implementation, focusing on the situation in China, in order to attract the attention of clinicians, raise awareness, strengthen prevention and control, and promote in-depth research for these diseases.
