New and Revised Topics in 2021
To determine the feasibility of enrolling pregnant women with ZIKV/HIV co-infection, HIV infection alone, ZIKV infection alone, and women without either infection.The central nervous system seems particularly vulnerable to the rubella virus especially if the virus is acquired prior to the first 16 weeks of gestation. Congenital rubella syndrome is described by the CDC as hearing loss, mental retardation, cardiac malformations, and eye defects. The rubella virus can slow cell replication. This causes intrauterine growth retardation and a failure of cell differentiation during fetal organ formation. Tissue damage seems to occur from the inflammatory response to the infection. Myocarditis, pneumonitis, hepatosplenomegaly and vascular stenosis can also be present. As seen with other severe congenital infections, signs and symptoms may continue to develop until 10 or 20 years of age. Late clinical signs of this disease include insulin-dependant diabetes, thyroid abnormalities, hypoadrenalism, hearing loss, and eye damage. 6.

Neonatal risk factors include antenatal, intrapartum stress (perinatal asphyxia), congenital anomalies, male sex, multiple gestations, concurrent neonatal disease processes, Prematurity, immaturity of the immune system, invasive admission procedures, and antimicrobial therapies. Baseline and follow-up medical, medication, substance use and other risk factor history were obtained by interview and medical record abstraction. Medical history included a recent history of symptoms consistent with ZIKV infection in the women, their sexual partners and household members. Fetal ultrasounds (US) were performed (or data abstracted from clinically performed US) in the first, second and third trimesters. Increased risk of severe illness during pregnancy from viral infections has been reported during pandemics of influenza, Ebola, and Lassa fever, even in HIV- uninfected women (32). With regards to the effect of the past ZIKV outbreak on pregnant WLHIV, there was a case report of an immunosuppressed pregnant woman on a combination ART (cART) regimen who presented with a mild disease (33). While the pregnant woman had a rapid and complete recovery, her severely affected fetus died at 20 weeks' gestation (33).
Considering the potential for more severe ZIKV disease in pregnant WLHIV, it is very relevant to examine pregnant women with both ZIKV and HIV infections to assess the consequences of co-infection on both mother and infant health. Varicella is the member of the herpes virus family that commonly causes chicken pox as well as varicella zoster. Most women of childbearing age have been exposed to or have contracted this virus; those that have not should receive the varicella vaccine prior to pregnancy. Symptoms of varicella are usually present 10 to 20 days after exposure and include fever, malaise, and an itchy rash. The maculopapular rash eventually forms vesicles and crusts over. Potential complications include pneumonia, encephalitis, arthritis, and bacterial cellulitis. If the virus is contracted early in pregnancy, the damage is likely to be cutaneous musculoskeletal, neurological and ocular.
Acute toxoplasmosis in a pregnant woman often goes undetected and undiagnosed. Maternal transmission occurs from consumption of poorly cooked meat, or by ingestion of infected cat feces. Risk of transmission is highest in the 3rd trimester. First trimester transmission usually ends in spontaneous abortion. Clinical questioning after the identification of an infected infant often leads to reflection and memories of a period of enlarged lymph nodes and fatigue but no fever. Women often report a mononucleosis-like syndrome that may have a febrile course, with malaise, headache, fatigue, sore throat, and sore muscles. When newborns acquire syphilis from hematogenous spread across the placenta, the effects are on the major organ systems of the fetus, especially the central nervous system. Common presentations of the infected infant are hepatosplenomegaly, jaundice, low birth weight, intrauterine growth retardation, anemia, and osteochondritis.

If the newborn is severely compromised and the oxygen levels continue to be low, regional tissue damage can result. Ischemic or necrotic areas in the lungs, heart, brain or gastrointestinal system provide a receptive environment for colonization and overgrowth of normal bacterial flora. This overgrowth of bacteria is one of the most common sources of neonatal sepsis. Damaged tissue can be repaired only if the infectious process is reversed and adequate tissue perfusion is restored. With introduction of ZIKV, Brazil witnessed an epidemic of microcephaly cases among newborns. According to the most recent Pan American Health Organization (PAHO) report, 14,558 suspected cases of microcephaly and other central nervous system (CNS) malformations were reported in Brazil during 20152017 as compared to an annual average of 163 cases of microcephaly during 20012014 (5). From 2015 to 2017, 27 countries and territories in the Americas (including the U. S. and Puerto Rico) reported confirmed cases of birth defects and other abnormalities associated with ZIKV infection (3).
Early identification of causative agents in the mother may help in the management of the infant. There are many reasons for the increased susceptibility of the newborn to widespread infection. The infants birth weight, chronologic, and gestational age at the onset of sepsis also has an impact on the expected mortality rate. Between 5 and 50 of infants with early-onset sepsis will succumb compared with a mortality rate of 10 to 20 with late-onset sepsis. The rate of sepsis in term infants in 0. 8 cases per 1,000 live births, and the mortality rate is 2. 3. Two or more maternal risk factors escalate the risk to 4 to 5. The studies involving human participants were reviewed and approved by Institutional Ethics Committees and the IRBs at the following institutions in Puerto Rico, mainland US, and Brazil: San Juan Hospital Research Unit, San Juan, Puerto Rico; University of Puerto Rico, San Juan, Puerto Rico; Children's Diagnostic & Treatment Center, Inc. , Ft.
Typical presentation is tachypnea, barrel chest, and an increased oxygen requirement. The infant may have interstitial infiltrations, hepatosplenomegaly, and increased eosinophils. Diagnosis is based on physical examination and conjunctivitis. Leukocytes are removed from blood products through filtration, washing and freezing to reduce the risk of febrile, nonhemolytic transfusion reactions and alloimmunization to HLA antigens. The function and proliferation of donor lymphocytes are inhibited by irradiation, to decrease the risk of post-transfusion graft-versus-host disease (GVHD) in immunocompromised patients. Because of the extremely high mortality of such infants, several ancillary therapies have been tried in addition to the conventionally accepted treatments of assisted ventilation, crystalloid fluid administration, and infusions of bicarbonate, antibiotics and vasopressor agents. The first of these approaches consists of treatment to replace or supply specific immune factors.

While remarkable strides have been made in the treatment of pregnant WLHIV over the last decade, resulting in immune restoration for their own health and the prevention of MTCT, the occurrence of ZIKV infection among pregnant WLHIV raises serious concerns regarding the ability of ART to suppress HIV RNA levels and prevent MTCT of both viruses. There is also a growing number of significant adverse infant outcomes, particularly those related to the CNS, following prenatal ZIKV infection (36), and because HIV is also a neurotropic virus, the ability of a pregnant WLHIV to maintain HIV RNA suppression will be critical for her child's health.
The average adult dose administered is 2 units; pediatric doses are generally calculated as 5 to 15 mL/kg. Human Papilloma Virus (HPV) genital warts or condylomata acuminate can cause laryngeal papillomatosis in the newborn demonstrated by a weak cry or hoarseness if the mother is not treated. The newborn may have stridor or other respiratory symptoms. The presence of these warts during vaginal delivery can be extremely uncomfortable. Intrapartal transmission is possible if the warts are visible. Prenatal treatment is associated with low complications and recurrence rate. The treatment alleviates the need for a cesarean delivery. Examination, treatment and follow-up of sexual partners are important aspects of treatment, because 50 percent of partners are infected. The Journal of the American College of Radiology (JACR), in collaboration with the ACR AC Patient Engagement Subcommittee, has launched Patient Summaries as a new publication category, representing an important, new initiative to have patients (laypersons) summarize AC recommendations for patients.
Harris, PhD); University of Miami Miller School of Medicine, Miami, FL (Gwendolyn Scott, MD; Charles Mitchell, MD; Grace Alvarez, FMD; Anai Cuadra, PhD). We are thankful for the support of Rohan Hazra, M. D. (NICHD); Walla Dempsey, Ph. D. (NIAID) and the Westat professionals Barbara Driver, RN, MS; Fatima Jones, Ph. D. ; Patty Chen, M. S. ; Sarah Ezzi, B. S. ; and John Quarantillo, B. S. Other risk factors known to be associated with neonatal infection are antenatal or intrapartal asphyxia, iatrogenic complications of treatment modalities, and postnatal invasive procedures. A predisposition to develop sepsis has been noted in low birth weight babies, placed on Indomethacin therapy for treatment of patent ductus arteriosus. Stress in any form inhibits the newborns ability to fight infection for several reasons. It increases the metabolic rate, thus requiring more oxygen and energy to support or sustain the bodys vital functions.
Plasma (Fresh or Fresh Frozen) consists of water (91), plasma proteins including essential clotting factors (7), and carbohydrate (2). Each unit is the volume removed from a unit of whole blood (200-250 mL. Plasma helps control bleeding due to blood loss or blood clotting disorders related to liver disease and failure, disseminated intravascular coagulation (DIC), over anticoagulation with warfarin, all congenital or acquired clotting factor deficiencies, and dilutional coagulopathy resulting from massive blood replacement. Storage in liquid state results in the loss of labile clotting factors V and VIII, so that only plasma that has been fresh frozen can be used to treat factor V and VIII deficiencies. The dosage depends on clinical situation and assessment of prothrombin time (PT), partial thromboplastin time (PTT), or a specific factor assays. D (Rh)-negative individuals do not develop anti-D in the absence of specific exposure, but there is a high incidence of antibody development (alloimmunization) after exposure to D. Two common methods of sensitization to these RBC antigens are by transfusion or fetomaternal hemorrhage during pregnancy and delivery.

There is often a bilaterally superficial peeling of the skin on the neonatal palms and soles. Nonimmune hydrops is a very common presentation in congenital syphilis. The symptomatology of perinatal syphilis is similar to that of any other viral infection that spreads hematogenously from the mother to the placenta and on to the developing fetus. A lumbar puncture for CSF analysis and radiographs of the long bones facilitate the definitive diagnosis. Congenital neurosyphilis is always a consideration, and the CSF should be examined for the presence of spirochetes. X-ray changes such as blurring of the epiphyseal borders demonstrate recent fetal infection, and periostitis represents prolonged involvement. It is anticipated the ordering physicians and radiologists will welcome these publications, as the summaries are intended to help patients understand what tests are appropriate for their situation, and are designed to help ordering physicians and radiologists better communicate the reason they are requesting, or performing, a particular imaging test.
The ABO blood group system is clinically the most significant because A and B antigens elicit the strongest immune response. The presence or absence of A and B antigens on the RBC membrane determines the individuals ABO group. The ability to make A or B antigens is inherited. Antibody formation in the absence of specific exposure to antigen is unique to the ABO system. Antibody directed against the missing antigen(s) is produced by the age of 3 months in neonates. Study design, development, and oversight were provided by the HIV ZIP Protocol Team (GS, MM-P, AA, NC, JM, KP, PW, BK, and PG). In addition, support in the following areasstudy development and management, regulatory oversight, data management, laboratory, and technology and logisticswas provided by Westat, Rockville, MD (DM and FW). Additional support for study development was provided by RTI International, Research Triangle Park, NC (JL). All authors contributed to the article and approved the submitted version. A fetus infected with rubella often has cardiac defects and deafness.
Congenital cerebral malformations and dysfunction in fetuses and newborns following the 2013 to 2014 Zika virus epidemic in French Polynesia. Eurosurveillance. (2016). doi: Study visits occurred once per trimester during pregnancy, at delivery and 6 weeks post-partum. At baseline, demographic characteristics were collected including the city of residence, education, occupation (self/partner), household characteristics (e. g. , city/suburb/ rural, number of windows/doors, sanitation methods, presence of animals, smoking and substance use, and environmental exposures such as pesticides). A targeted maternal physical examination was also conducted which included general appearance and an assessment of signs and symptoms of acute ZIKV infection such as fever, rash, arthralgia, myalgia, pruritus, headache, eye pain, conjunctivitis, and lymphadenopathy. No single clinical sign or single abnormal laboratory test is highly associated with sepsis, but combinations of the above signs strongly suggest sepsis or meningitis. Therefore, a prudent physician identifies infants at high risk and provides for extremely close observation of vital signs and overall status of those children in the first 24 hours of life.

Anti-D can complicate future transfusions and pregnancies. For the D (Rh)-negative individual, exposure to D should be avoided by the use of Rh-negative blood products. In the case of Rh-negative mother and Rh-positive fetuses, exposure to D can be treated using Rh immunoglobulins, which will prevent anti-D formation. Freezing: RBCs frozen within 7 days of blood collection remain viable for 7 to 10 years. Removal of the hypertonic freezing preservative (glycerol) before transfusion eliminates all of the plasma and 99 of WBCs. Thawing and deglycerolization of RBCs requires an additional 90 minutes of preparation time and reduces shelf life to 24 hours after this additional manipulation. Freezing is also effective method of storing rare blood types and Autologous RBCs. A mother with a fever or who has been ill prior to delivery can pass the infection on to her infant. If a maternal temperature of 101?F is noted at delivery, a septic work-up is indicated. Maternal cervical or amniotic fluid cultures may be necessary to determine the causative agent of elevated temperature. If maternal illness suggests viral infection, neonatal viral cultures should be drawn.
Therefore, we have undertaken a prospective cohort study to investigate both maternal and child effects of HIV and ZIKV co-infection in pregnant women. Delineation of adverse effects will allow formulation of standard-of-care recommendations to minimize adverse effects but enable continuation of preventive therapy. Currently, it is unclear whether HIV infection increases the susceptibility to ZIKV infection and whether ZIKV infection worsens HIV infection, particularly during pregnancy. Importantly, two potential interactions between ZIKV and HIV infections in pregnant women could adversely influence maternal health and facilitate vertical transmission of both virus imposing deleterious effects on the fetus and infants: (1) the impact of the ZIKV on the immune system of the mother living with HIV, and (2) the dysfunctional effect of ZIKV on the placenta. Packed RBCs consists primarily of RBCs, a small amount of plasma, and about 100 mL anticoagulant/preservative solution in a total volume of about 250 to 300 mL/unit. It helps restore blood volume while preventing fluid overload, improves blood oxygen carrying capacity, and reduces risk of metabolic complications.
To reduce the risk of specific transfusion-related complications, blood products may receive further processing or treatment: Feasibility in enrolling a total of 200 pregnant women within a year, with a target of 150 WLHIV across all sites, 50 HIV-uninfected women sites in the continental United States only, and a minimum of 20 women who are co-infected with HIV and ZIKV will be assessed by monitoring total accrual, accrual by study sites and accrual into the four study groups. If the feasibility phase proves successful, enrollment into Phase II will begin with the goal of enrolling up to 1,800 pregnant women at risk for ZIKV, bringing to total target enrollment to 2,000. There are several known maternal factors associated with neonatal sepsis and infection: low socioeconomic status, malnutrition, no prenatal care, substance abuse, rupture of membranes prior to 37 weeks, substance abuse, presence of urinary tract infection at delivery, peripartum infection, clinical amnionitis, and general bacterial colonization.
Infants can have intrauterine growth retardation, microcephaly, cerebellar and cortical atrophy, cataracts, and chorioretinitis. Viral infection in the last 3 weeks of pregnancy will infect one in four newborns. The severity of newborn disease is determined by the timing of the exposure. Infections are generally severe if contracted within 4 days before delivery and 2 days after delivery. Severe viral respiratory distress with significantly depleted maternal passive antibody transmission puts the infant at an even greater risk for other complications. Microcephaly was not systematically examined and reported following ZIKV infection before the outbreak in the Americas. Besnard et al. retrospectively reported a summary of the 20132014 ZIKV outbreak in French Polynesia (6). They described ten cases of congenital cerebral malformations in fetuses and newborns including eight with major brain lesions and severe microcephaly. Antibody/cell complexes also active the complement cascade, resulting in the release of numerous active substances and RBC lysis. The large antibody/cell complexes also become trapped in capillaries, where they may cause thrombotic complications to vital organs, and in the reticuloendothelial system, where they are removed from circulation by the spleen.
This may mean granulocyte transfusions in infants with neutropenia and total body depletion of neutrophils reflects in absent or decreased bone marrow stores, or infusion of pooled adult hyper immune globin to try to collect specific antibody defenses. One of the initial diagnostic clues to infection can be obtained from a complete blood count. A septic infant may demonstrate Leukopenia, especially neutropenia with a cell count of polymorphonuclear leukocytes less than 5000/mm3, or may have a large number of immature leukocytes, in particular bands, with band leukocyte ratio greater than 0:2. The following are indications of bacterial infection.

Non-ABO RBC antigen-antibody reactions usually do not produce powerful immediate hemolytic reactions, but several do have clinical significance. After A and B, D is the most immunogenic antigen. It is part of the Rhesus system, which includes C, D and E antigens.
Learn more Coagulase-negative staphylococcus has been identified as a major cause of nosocomial infections. Low birth weight, multiple gestation, and prolonged hospitalization are significant factors for nosocomial infection. Yeast infections often occur if previous antibiotic therapy has been given. This infection is also associated with colonization of vascular catheters, assisted ventilation, and necrotizing enterocolitis. Chlamydia is a bacterium that grows between cells. It is one of the most common sexually transmitted diseases. Chlamydia conjunctivitis can present in the newborn with a very watery discharge that may progress to purulent exudates. Application of erythromycin ointment at birth for ocular prophylaxis will successfully treat both Chlamydia and gonococcal conjunctivitis. Pneumonia can occur in newborns that have contracted Chlamydia from their mothers genital tract.
