Serologic screening and infectious disease consultation (IDC): Indicated in heart, lung, liver (HLL) solid organ transplants (SOT) for measles, mumps, rubella, and varicella.

BACKGROUND: Solid organ transplant (SOT) recipients are a special group of patients who require comprehensive evaluation for preventable infectious diseases before transplantation. The main aim of our study was to investigate the number of heart, lung, and liver (HLL) transplant recipients who were evaluated for their immune status against measles, mumps, rubella (MMR), and varicella (VZV). As a secondary aim, we investigated whether pre-transplant infectious disease consultation (IDC) improves vaccination rates. METHODS: This study was an institution-based retrospective analysis of HLL transplant recipients born in or after 1957 and evaluated at Mayo Clinic, FL Transplant Center between January 1st, 2016 and December 31st, 2017. Data collection was obtained from electronic medical records. The vaccination rates were compared by univariate analysis based on IDC and no ID consultation (NIDC). RESULTS: One hundred and eighty-seven (77%) of a total 242 patients received an IDC pre-transplantation. Varicella IgG levels were screened in all 187 IDC candidates. Among the 187 IDC patients, mumps, measles, and rubella IgG serologies were performed in 9 (5%), 21 (11%), and 51 (27%), respectively. Among all 242 patients, vaccines given included 2 (0.8%) MMR, 10 (4.1%) varicella and 85 (35.12%) Zostavax. Univariate analysis revealed that Zostavax was given to 76 (40.6%) pre-transplant IDC patients and only in 9 (16.7%) NIDC patients (P < .001). CONCLUSIONS: Despite the relatively high IDC rate, patients' screened numbers for MMR IgG levels were low. Results pointed out the need for MMR protocol-driven serologic screening as well as for VZV and IDC prior to transplantation to increase vaccination rates.

Preventative Care in the Patient with Inflammatory Bowel Disease: What Is New?

Patients with inflammatory bowel disease (IBD) do not receive routine preventative care at the same rate as general medical patients. This patient population is at increased risk of vaccine preventable illness such as influenza and pneumococcal pneumonia. This review will discuss health maintenance needs and preventative care issues in patients with IBD.

Case of mumps orchitis after vaccination.

We present a case of mumps orchitis after vaccination. A 35-year-old man visited the emergency unit of our hospital for fever and right testicular pain on 7 January 2012. Two weeks before the visit, he underwent vaccination for mumps. After 7 days of hospitalization, the patient recovered from fever and testicular pain. Scrotal magnetic resonance imaging suggested right orchitis, and an increased level of serum mumps immunoglobulin M and immunoglobulin G indicated an initial infection of mumps virus. The peak value of immunoglobulin G showed 106 enzyme immunoassay unit 5 weeks after vaccination, which was 10-fold higher than the ordinary rise of a vaccinated individual. This fact leads to two possibilities. One is this happened as an adverse event of vaccination, and the other is that he actually had a wild-type infection at the same time as vaccination. There are some reports regarding adverse events of mumps vaccine; however, they might include wild-type infection.

Mumps: not an innocent bystander in solid organ transplantation.

Recently two major outbreaks of mumps have occurred: in the UK more than 56,000 cases were notified between 2004 and 2005, and in the United States, 6,584 cases were reported in 2006. Most patients were young healthy adults, in whom mumps normally has a benign course. Little is known about mumps in the immunocompromised patient. Here, we report a case of a 56-year renal transplant recipient who developed acute irreversible transplant failure due to interstitial nephritis caused by mumps. RNA of the mumps virus was detected in the urine as well as in a renal biopsy. In view of the ongoing presence of the mumps virus in the population, one should be aware of the possible occurrence of this infection in immunocompromised patients.

The origin and spread of a mumps epidemic: United kingdom, 2003-2006.

BACKGROUND: The United Kingdom (UK) underwent a massive epidemic of mumps from 2003 through 2006. The origin and spread was mapped in 350 general practices that used office computers to contribute comprehensive medical information on approximately 3 million patients to the General Practice Research Database (GPRD). METHODS: The continuous 3-month cumulative incidence of mumps (2003-2006) was estimated by dividing the number of diagnosed cases of mumps each 3 months by the population at risk according to age, region, practice, and calendar time. The effect of the measles, mumps, and rubella (MMR) vaccine was estimated by comparing vaccine exposure of those diagnosed with mumps and those who were not. RESULTS: There were 5683 cases of mumps recorded in the Database over the 4-year time period. As the Database represents about 5% of the UK population, we estimate that there were more than 100,000 cases of mumps diagnosed in the UK during these 4 years. The epidemic appears to have started in one practice in Wales in the first 6 months of 2003 and then spread slowly north and east, reaching a peak in 2005. Young adults aged 18-24 years were at the highest risk. There were 3 major MMR vaccination campaigns (1988-1989, 1997, and 2004-2005) that by 2006 provided more than 70% protection against mumps in children younger than 18 years of age. Protection was higher in those who had received 2 doses of the vaccine. CONCLUSION: A comprehensive program of medical information generated by selected general practitioners has provided a sound basis for the real-time recording of the origin, spread, and scope of an infectious disease.

Risk factors for mumps at a university with a large mumps outbreak.

OBJECTIVES: Routine measles-mumps-rubella (MMR) vaccine use has greatly decreased the incidence of mumps in the U.S. However, a resurgence of mumps occurred in 2006. We investigated the large outbreak at a university and assessed risk factors for disease. METHODS: We described the outbreak and conducted a case-control study. We interviewed case students (identified from student health service and health department records) and control students (selected from a randomly ordered administrative list) and assessed their vaccination status. We compared case students with > or = 2 MMR doses and control students with > or = 2 MMR doses in univariate and multivariate analyses. RESULTS: The mean age of the 174 case students was 20.9 years; 65% were women. Ninety-seven case students and 147 control students were enrolled in the study. Two-dose MMR coverage was 99% among case and control students with complete records. Only 33% of case students reported exposure to someone with mumps. Case students were more likely than control students to be aged 18 to 19 years (vs. aged 22 years, adjusted odds ratio [AOR] = 5.55; 95% confidence interval [CI] 2.09, 14.74), to report exposure to mumps (AOR=2.31, 95% CI 1.13, 4.73), and to have worked/volunteered on campus (AOR=2.91, 95% CI 1.33, 6.33). Also, women in dormitories had increased odds of mumps compared with men in dormitories. CONCLUSION: High two-dose MMR coverage was not sufficient to prevent the outbreak. Further study is needed to better understand the effects of dormitory residency and gender on mumps transmission. Clinicians should be vigilant for mumps in young adults presenting with parotitis regardless of immunization history.

Mumps outbreak in Jerusalem affecting mainly male adolescents.

From mid-September 2009 to 7 December 2009, 173 cases of mumps have been reported in the Jerusalem District. Most cases (82.1%) were male adolescents (median age 14.5 years) who are students in religious boarding schools. The majority of them (74%) are appropriately vaccinated for their age; 67% had received two doses of mumps-containing vaccine. An epidemiologic connection has been reported with visitors from New York, some of whom had recently had mumps.

Rubella, rubeola, and mumps in pregnant women: susceptibilities and strategies for testing and vaccinating.

OBJECTIVE: To estimate rubella, rubeola, and mumps (MMR) susceptibilities in pregnant women and determine the percentage not immune to rubeola or mumps, depending on rubella immunity status. A secondary objective was to assess costs of vaccination and testing programs aimed at eliminating these viral susceptibilities to determine an optimal strategy. METHODS: This was an observational study of women presenting for prenatal care. All women had MMR antibody titers measured. Viral susceptibilities were compared by age, gravidity, parity, and recall of vaccine booster. A logistic regression was performed to assess for predictors of MMR immunity. A cost comparison of different screening and vaccination strategies was performed. RESULTS: Overall, 91 (9.4%) women were susceptible to rubella, 161 (16.5%) to rubeola, and 159 (16.3%) to mumps. Three hundred seventeen (32.6%) were susceptible to at least 1 virus, whereas only 17 (1.7%) were susceptible to all 3. Of the women who were immune to rubella, a large percentage were not immune to either rubeola or mumps (n = 226, 25.6%). Only 74.2% of women who knew they had a booster vaccine were immune to all components of the MMR vaccine. Receiving a booster was predictive of immunity to all 3 viruses. A cost analysis demonstrated that broader screening strategies are more comprehensive and more expensive. CONCLUSION: The current screening and vaccine program has left many reproductive-aged women susceptible to rubella, rubeola, and mumps infections. Perhaps a more comprehensive viral screening program is needed to ensure immunity.

Evaluation of the immune status against measles, mumps, and rubella in adult allogeneic hematopoietic stem cell transplantation recipients.

BACKGROUND: Previous studies have shown that most patients lose immunity to measles, mumps, and rubella (MMR) during long-term follow-up after allogeneic hematopoietic stem cell transplantation (HSCT), and immunizations against them have been investigated. However, these previous studies mainly targeted pediatric patients and information in adult patients is still insufficient. METHODS: We evaluated the immunity to MMR in 45 adult allogeneic HSCT patients. None of these patients received vaccination after HSCT. RESULTS: The seropositive rates at six years after allogeneic HSCT were estimated to be less than 44% for measles, less than 10% for mumps, and less than 36% for rubella. Thirteen of the 16 female patients who were 16-39 years old were negative or equivocal for rubella. Patients who developed grade II-IV acute graft-versus-host disease tended to become seronegative for measles and rubella at two years after HSCT, although the difference was not statistically significant. CONCLUSIONS: This study showed that most adult patients lost immunity to MMR after allogeneic HSCT. Although we did not evaluate the safety and efficacy of vaccination in this study, most HSCT guidelines recommend vaccination for HSCT recipients without active chronic graft-versus-host disease or ongoing immunosuppressive therapy at 24 months after HSCT. Immunization against rubella is especially important for female patients of reproductive age. Further studies will be necessary to evaluate the effect of vaccination on the antibody response in adult allogeneic HSCT recipients.

Long-term immunity to measles, mumps and rubella after MMR vaccination among children with bone marrow transplants.

Measles, mumps and rubella (MMR) vaccine-induced long-term immunity was studied in 30 children with bone marrow transplants (BMT). Immunity at baseline for MMR was 13.3, 33.3 and 66.6%, respectively. MMR vaccination failed to induce adequate and persistent responses to measles and mumps; seropositivity at 1 and 12 months for measles was 26.6 and 23.3% and for mumps 46.6 and 36.6%, respectively. In contrast, 27 of 30 children with a BMT were immune to rubella 1 month after immunization and retained protective antibody levels at 12 months. The MMR-induced anamnestic responses to rubella among all responders were associated with the production of high avidity antibodies. We conclude that a single dose of MMR given at 2 years after BMT induces suboptimal and short-lived immune responses to measles and mumps; a second dose should be recommended for paediatric BMT recipients.

An outbreak of mumps among young adults in Vancouver, British Columbia, associated with 'rave' parties.

UNLABELLED: In early 1997 an unexpectedly high number of cases of mumps was reported in Vancouver, British Columbia. METHODS: A case control study was conducted to address four objectives: 1) Describe the outbreak and the population at risk, 2) examine the impact of mumps on this population, 3) identify personal risk factors for infection, and 4) test the hypothesis that social gatherings, 'rave' parties in particular, were a risk factor in this outbreak. RESULTS: Mumps infection was associated with: attending a rave party [OR = 17; 95% CI: 2.7-710], residing in Vancouver [OR = 3.7; 95% CI: 1.4-10], and contact with a person with mumps [OR = 13; 95% CI: 2-552], during the 'exposure' period. Vaccine effectiveness, ascertained by self-reported immunization status, was 80% [95% CI: 29%-96%]. CONCLUSIONS: Attendance at rave parties was associated with mumps infection during this outbreak. Many persons aged 17-40 may remain susceptible to mumps; in BC these persons are eligible for one dose of MMR and should be encouraged to be vaccinated.

[Virological evaluation of mumps meningitis following vaccination against mumps].

1) We report 5 cases of aseptic meningitis following vaccination against mumps. Of the 5 cases, 4 cases were diagnosed as mumps meningitis. 2 cases received monovalent mumps vaccine and the other 2 MMR vaccine. They consisted of 2 boys and 2 girls, aged 2 years and 2 months to 4 years and 5 months. The period between vaccination and symptoms ranged from 15 days to 20 days (mean 18 days). Cerebrospinal fluid of the cases contained 507 to 2688 cells/mm3. Eruption was observed in the 2 cases who received MMR vaccine, while parotid swelling was not seen in any case. 2) In all 4 cases, IgM antibody to mumps virus in the cerebrospinal fluid was detected by the ELISA or EIA methods. Causative organism of the fifth case was obscure. 3) PCR (Polymerase Chain Reaction) tests revealed that mumps virus isolated from 2 cases were of vaccine strain origin. 4) To evaluate the frequency of mumps meningitis following vaccination, it seems important to investigate carefully the number of children who received the vaccine and to exclude the cases of aseptic meningitis caused by other agents. On the other hand, cases of young infants tend to be overlooked because of atypical signs.

[Etiology of epidemic parotitis]. / A parotitis epidemica etiológiája.

Blood samples of 204 acute parotitis patients in a fifteen month period (1991-1992) were systematically examined for IgM, IgA, IgG antibodies of mumps and parainfluenza-virus 1, 2, 3 (PIV) by immunofluorescent test (IFT) and, in special cases several other virological examinations have been done. The etiological role of mumps-virus, parainfluenza-virus 1, 2, 3, one of the other viruses was confirmed in 76.0%, 1.5%, 6.3%, 1.5%, 4.9% of the cases, respectively. The etiology remained unknown in 9.8%. There were clinical symptoms of meningitis or orchitis in some and lymphadenopathy in several of the parainfluenza-virus caused parotitis patients. The authors conclude, that the parainfluenza-viruses are the second most frequent etiological agents of parotitis next to mumps-virus. They found that the Respiratory Syncytial Virus (RSV) also play etiological role in parotitis. This observation should be confirmed in the future by some other kind of virological tool too. The authors call attention to the difficulties and pitfalls of the virological serology in the infections caused by paramyxoviruses (PMV).
