The Role of Faith-Based Organizations in Improving Vaccination Confidence & Addressing Vaccination Disparities to Help Improve Vaccine Uptake: A Systematic Review.

The COVID-19 pandemic underscored the importance of vaccination to support individual health across the life-course, with vaccination playing a central strategy role in mitigating transmission and disease. This required unprecedented mobilization and coordination across all sectors to meet people where they are, enable equitable access, and build vaccination confidence. A literature search was conducted with combinations of the keywords and variations of vaccination and faith-based organizations (FBOs). Search inclusion criteria were: (1) FBO programs that supported public health emergency efforts, including vaccination efforts as the primary outcome; and (2) articles written in English language. A total of 37 articles met inclusion criteria (n = 26 focused on general public health campaigns, n = 11 focused on vaccination efforts). The findings related to public health campaigns fell into four themes: FBO's ability to (1) tailor public health campaigns; (2) mitigate barriers; (3) establish trust; and (4) disseminate and sustain efforts. The findings related to vaccine uptake efforts fell into three themes: (1) pre-pandemic influenza and HPV vaccination efforts, (2) addressing vaccine disparities in minority communities, and (3) enabling COVID-19 vaccination. This review demonstrated that FBOs have a vital role in both public health campaigns and vaccination initiatives to support high vaccine uptake and confidence.

Advancing maternal and perinatal health in low- and middle-income countries: A multi-country review of policies and programmes.

The Sustainable Development Goals prioritize maternal mortality reduction, with a global average target of < 70 per 100,000 live births by 2030. Current pace of reduction is far short of what is needed to achieve the global target. It is estimated that globally there are 300,000 maternal deaths, 2.4 million newborn deaths and 2 million stillbirths annually. Majority of these deaths occur in low-and-middle-income countries. Global initiatives like, Ending Preventable Maternal Mortality (EPMM) and Every Newborn Action Plan (ENAP), have outlined the broad strategies for maternal and newborn health programmes. A set of coverage targets and ten milestones were launched to support low-and-middle-income countries in accelerating progress in improving maternal, perinatal and newborn health and wellbeing. WHO, UNICEF and UNFPA, undertook a scoping review to understand how country strategies evolved in different contexts over the past two decades to improve maternal survival and wellbeing, and how countries in similar settings could accelerate progress considering the changing epidemiology and demography. Case studies were conducted to inform countries in similar settings and various global initiatives. Six countries were selected based on standard criteria-Cambodia, Democratic Republic of the Congo, Georgia, Guatemala, Pakistan and Sierra Leone representing different stages of the obstetric transition. A conceptual framework, encapsulating the interrelated factors impacting maternal health outcomes, was used to organize data collection and analysis. While all six countries made remarkable progress in improving maternal and perinatal health, the pace of progress and the factors influencing the successes and challenges varied across the countries. The context, opportunities and challenges varied from country to country. Two strategic directions were identified for next steps including the need to implement and evaluate innovative service delivery models using an updated obstetric transition as an organizing framework and expanding our vision to address equity and well-being.

Maternal and newborn health for the urban poor: the need for a new mental model and implementation strategies to accelerate progress.

BACKGROUND: Urbanization challenges the assumptions that have traditionally influenced maternal and newborn health (MNH) programs. This landscaping outlines how current mental models for MNH programs have fallen short for urban slum populations and identifies implications for the global community. We employed a three-pronged approach, including a literature review, key informant interviews with global- and national-level experts, and a case study in Bangladesh. MAIN BODY: Our findings highlight that the current mental model for MNH is inadequate to address the needs of the urban poor. Implementation challenges have arisen from using traditional methods that are not well adapted to traits inherent in slum settings. A re-thinking of implementation strategies will also need to consider a paucity of available routine data, lack of formal coordination between stakeholders and providers, and challenging municipal government structures. Innovative approaches, including with communications, outreach, and technology, will be necessary to move beyond traditional rural-centric approaches to MNH. As populations continue to urbanize, common slum dynamics will challenge conventional strategies for health service delivery. In addition, the COVID-19 pandemic has exposed weaknesses in a system that requires intersectoral collaborations to deliver quality care. CONCLUSION: Programs will need to be iterative and adaptive, reflective of sociodemographic features. Integrating the social determinants of health into evaluations, using participatory human-centered design processes, and innovative public-private partnerships may prove beneficial in slum settings. But a willingness to rethink the roles of all actors within the delivery system overall may be needed most.

Addressing and Inspiring Vaccine Confidence in Black, Indigenous, and People of Color During the Coronavirus Disease 2019 Pandemic.

During the coronavirus disease 2019 (COVID-19) pandemic, we have witnessed profound health inequities suffered by Black, Indigenous, and People of Color (BIPOC). These manifested as differential access to testing early in the pandemic, rates of severe disease and death 2-3 times higher than white Americans, and, now, significantly lower vaccine uptake compared with their share of the population affected by COVID-19. This article explores the impact of these COVID-19 inequities (and the underlying cause, structural racism) on vaccine acceptance in BIPOC populations, ways to establish trustworthiness of healthcare institutions, increase vaccine access for BIPOC communities, and inspire confidence in COVID-19 vaccines.

Joint ESCMID, FEMS, IDSA, ISID and SSI position paper on the fair handling of career breaks among physicians and scientists when assessing eligibility for early-career awards.

BACKGROUND: Though women increasingly make up the majority of medical-school and other science graduates, they remain a minority in academic biomedical settings, where they are less likely to hold leadership positions or be awarded research funding. A major factor is the career breaks that women disproportionately take to see to familial duties. They experience a related, but overlooked, hurdle upon their return: they are often too old to be eligible for 'early-career researcher' grants and 'career-development' awards, which are stepping stones to leadership positions in many institutions and which determine the demographics of their hierarchies for decades to come. Though age limits are imposed to protect young applicants from more experienced seniors, they have an unintended side effect of excluding returning workers, still disproportionately women, from the running. METHODS: In this joint effort by the European Society of Clinical Microbiology and Infectious Diseases, the Federation of European Microbiological Societies, the Infectious Disease Society of America, the International Society for Infectious Diseases and the Swiss Society for Infectious Diseases, we invited all European Congress of Clinical Microbiology and Infectious Diseases-affiliated medical societies and funding bodies to participate in a survey on current 'early-career' application restrictions and measures taken to provide protections for career breaks. RECOMMENDATIONS: The following simple consensus recommendations are geared to funding bodies, academic societies and other organizations for the fair handling of eligibility for early-career awards: 1. Apply a professional, not physiological, age limit to applicants. 2. State clearly in the award announcement that career breaks will be factored into applicants' evaluations such that: • Time absent is time extended: for every full-time equivalent of career break taken, the same full-time equivalent will be extended to the professional age limit. • Opportunity costs will also be taken into account: people who take career breaks risk additional opportunity costs, with work that they did before the career break often being forgotten or poorly documented, particularly in bibliometric accounting. Although there is no standardized metric to measure additional opportunity costs, organizations should (a) keep in mind their existence when judging applicants' submissions, and (b) note clearly in the award announcement that opportunity costs of career breaks are also taken into account. 3. State clearly that further considerations can be undertaken, using more individualized criteria that are specific to the applicant population and the award in question. The working group welcomes feedback so that these recommendations can be improved and updated as needed.

Biochemical synthesis of gold nanoparticles from leaf protein of Nicotiana tabacum L. cv. xanthi and their physiological, developmental, and ROS scavenging responses on tobacco plant under stress conditions.

The stress conditions imposed by the impact of metal and non-metal oxide nanoparticles over plant systems enhances the synthesis of reactive oxygen species (ROS), resulting in oxidative damage at cellular level. The objective of this study was to synthesise the gold nanoparticles (GNps) from the leaves protein of Nicotiana tabacum L. cv. xanthi, its characterisation, and response on plant physiology and ROS scavenging activity on plants after exposure to different stresses. The authors have treated N. tabacum L. cv. xanthi plants with 100, 200, 300, 400, and 500 ppm biochemically synthesised GNps and examined physiological as well as biochemical changes. Results showed that biochemically synthesised GNps exposure significantly increased the seed germination (P < 0.001), root (P < 0.001), shoot growth (P < 0.001), and antioxidant ability (P < 0.05) of plants depending on bioengineered GNPs concentrations. Low concentrations (200-300 ppm) of GNps boosted growth by ∼50% and significantly increase in photosynthetic parameters such as total chlorophyll content (P < 0.05), membrane ion leakage (P < 0.05) as well as malondialdehyde (P < 0.05) content with respect to untreated plants under stress conditions. The high concentration (400-500 ppm) of GNps affected these parameters in a negative manner. The total antioxidant activity was also elevated in the exposed plants in a dose-dependent manner.

Citric acid based durable and sustainable flame retardant treatment for lyocell fabric.

Pyrovatex CP New, is a commonly used organophosphorus based flame retardant (FR) reagent for cellulosic materials. However, it has a drawback of high formaldehyde release when used with methylated melamine (MM) based cross-linker, a known carcinogenous compound. In the present approach, a durable and sustainable flame retarding recipe formulation for lyocell fabrics is developed using citric acid (CA) as a cross-linker. The FR finish was applied by pad-dry-cure process. The treated fabrics were characterized for surface morphology, elemental analysis, TG analysis, char study and FT-IR spectroscopy. Furthermore, flame retardancy, washing durability, formaldehyde release and breaking strength were also assessed, and compared with the conventional MM based FR recipe. The fabric samples treated with 400gL(-1) of FR with either 40 or 80gL(-1) of CA demonstrate flame retardancy even after 10 washing cycles. Furthermore, a 75% reduction in formaldehyde release is achieved. Higher char yield and lower decomposition temperature are found compared to untreated and FR+ MM treated lyocell. Such an improved sustainable recipe formulation can be used for lyocell fabric without any health risk in apparel wear.

RNAi down-regulation of cinnamate-4-hydroxylase increases artemisinin biosynthesis in Artemisia annua.

Cinnamate-4-hydroxylase (C4H) converts trans-cinnamic acid (CA) to p-coumaric acid (COA) in the phenylpropanoid/lignin biosynthesis pathway. Earlier we reported increased expression of AaCYP71AV1 (an important gene of artemisinin biosynthesis pathway) caused by CA treatment in Artemisia annua. Hence, AaC4H gene was identified, cloned, characterized and silenced in A. annua with the assumption that the elevated internal CA due to knock down may increase the artemisinin yield. Accumulation of trans-cinnamic acid in the plant due to AaC4H knockdown was accompanied with the reduction of p-coumaric acid, total phenolics, anthocyanin, cinnamate-4-hydroxylase (C4H) and phenylalanine ammonia lyase (PAL) activities but increase in salicylic acid (SA) and artemisinin. Interestingly, feeding trans-cinnamic acid to the RNAi line increased the level of artemisinin along with benzoic (BA) and SA with no effect on the downstream metabolites p-coumaric acid, coniferylaldehyde and sinapaldehyde, whereas p-coumaric acid feeding increased the content of downstream coniferylaldehyde and sinapaldehyde with no effect on BA, SA, trans-cinnamic acid or artemisinin. SA is reported earlier to be inducing the artemisinin yield. This report demonstrates the link between the phenylpropanoid/lignin pathway with artemisinin pathway through SA, triggered by accumulation of trans-cinnamic acid because of the blockage at C4H.

Equity improvements in maternal and newborn care indicators: results from the Bardiya district of Nepal.

Community-based maternal and newborn care interventions have been shown to improve neonatal survival and other key health indicators. It is important to evaluate whether the improvement in health indicators is accompanied by a parallel increase in the equitable distribution of the intervention activities, and the uptake of healthy newborn care practices. We present an analysis of equity improvements after the implementation of a Community Based Newborn Care Package (CB-NCP) in the Bardiya district of Nepal. The package was implemented alongside other programs that were already in place within the district. We present changes in concentration indices (CIndices) as measures of changes in equity, as well as percentage changes in coverage, between baseline and endline. The CIndices were derived from wealth scores that were based on household assets, and they were compared usingt-tests. We observed statistically significant improvements in equity for facility delivery [CIndex: -0.15 (-0.24, -0.06)], knowledge of at least three newborn danger signs [-0.026(-0.06, -0.003)], breastfeeding within 1 h [-0.05(-0.11, -0.0001)], at least one antenatal visit with a skilled provider [-0.25(-0.04, -0.01)], at least four antenatal visits from any provider [-0.15(-0.19, -0.10)] and birth preparedness [-0.09(-0.12, -0.06)]. The largest increases in practices were observed for facility delivery (50%), immediate drying (34%) and delayed bathing (29%). These results and those of similar studies are evidence that community-based interventions delivered by female community health volunteers can be instrumental in improving equity in levels of facility delivery and other newborn care behaviours. We recommend that equity be evaluated in other similar settings within Nepal in order to determine if similar results are observed.

Leaf Senescence and GABA Shunt.

Leaf senescence is highly regulated and complex developmental process that involves degradation of macromolecules as well as its recycling. Senescence process involves loss of chlorophyll, degradation of proteins, nucleic acid, lipid and mobilization of nutrients through its transport to the growing parts, developing fruits and seeds. Nitrogen is the most important nutrient to be recycled in senescence process. GABA-transaminase (γ-aminobutyric acid) is found to play very important role in nitrogen recycling process through GABA-shunt. Therefore, it is of interest to review the significance of GABA shunt in leaf senescence.

Newborn survival in Bangladesh: a decade of change and future implications.

Remarkable progress over the last decade has put Bangladesh on track for Millennium Development Goal (MDG) 4 for child survival and achieved a 40% decline in maternal mortality. However, since neonatal deaths make up 57% of under-five mortality in the country, increased scale up and equity in programmes for neonatal survival are critical to sustain progress. We examined change for newborn survival from 2000 to 2010 considering mortality, coverage and funding indicators, as well as contextual factors. The national neonatal mortality rate has undergone an annual decline of 4.0% since 2000, reflecting greater progress than both the regional and global averages, but the mortality reduction for children 1-59 months was double this rate, at 8.6%. Examining policy and programme change, and national and donor funding for health, we identified various factors which contributed to an environment favourable to newborn survival. Locally-generated evidence combined with re-packaged global evidence, notably The Lancet Neonatal Series, has played a role, although pathways between research and policies and programme change are often complex. Several high-profile champions have had major influence. Attention for community initiatives and considerable donor funding also appear to have contributed. There have been some increases in coverage of key interventions, such as skilled attendance at birth and postnatal care, however these are low and reach less than one-third of families. Major reductions in total fertility, some change in gross national income and other contextual factors are likely to also have had an influence in mortality reduction. However, other factors such as socio-economic and geographic inequalities, frequent changes in government and pluralistic implementation structures have provided challenges. As coverage of health services increases, a notable gap remains in quality of facility-based care. Future gains for newborn survival in Bangladesh rest upon increased implementation at scale and greater consistency in content and quality of programmes and services.

Newborn survival in Nepal: a decade of change and future implications.

Nepal is on target to meet the Millennium Development Goals for maternal and child health despite high levels of poverty, poor infrastructure, difficult terrain and recent conflict. Each year, nearly 35,000 Nepali children die before their fifth birthday, with almost two-thirds of these deaths occurring in the first month of life, the neonatal period. As part of a multi-country analysis, we examined changes for newborn survival between 2000 and 2010 in terms of mortality, coverage and health system indicators as well as national and donor funding. Over the decade, Nepal's neonatal mortality rate reduced by 3.6% per year, which is faster than the regional average (2.0%) but slower than national annual progress for mortality of children aged 1-59 months (7.7%) and maternal mortality (7.5%). A dramatic reduction in the total fertility rate, improvements in female education and increasing change in skilled birth attendance, as well as increased coverage of community-based child health interventions, are likely to have contributed to these mortality declines. Political commitment and support for newborn survival has been generated through strategic use of global and national data and effective partnerships using primarily a selective newborn-focused approach for advocacy and planning. Nepal was the first low-income country to have a national newborn strategy, influencing similar strategies in other countries. The Community-Based Newborn Care Package is delivered through the nationally available Female Community Health Volunteers and was piloted in 10 of 75 districts, with plans to increase to 35 districts in mid-2013. Innovation and scale up, especially of community-based packages, and public health interventions and commodities appear to move relatively rapidly in Nepal compared with some other countries. Much remains to be done to achieve high rates of effective coverage of community care, and especially to improve the quality of facility-based care given the rapid shift to births in facilities.

Respiratory syncytial virus (RSV) community-acquired pneumonia (CAP) in a hospitalized adult with human immunodeficiency virus (HIV) mimicking influenza A and Pneumocystis (carinii) jiroveci pneumonia (PCP).

BACKGROUND: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infections in young children, the elderly, and immunocompromised hosts, but RSV is a rare cause of community-acquired pneumonia (CAP) in hospitalized adults with human immunodeficiency virus (HIV). In patients with HIV, CAP is most frequently attributable to the usual bacterial respiratory pathogens that cause CAP in immunocompetent hosts, eg, Streptococcuspneumoniae or Hemophilus influenzae. Adults with HIV are also predisposed to intracellular CAP pathogens, ie, Mycoplasmatuberculosis, Salmonella spp., Pneumocystis (carinii) jiroveci (PCP), cytomegalovirus, and Legionella spp. This year, co-circulating in the community during influenza season were strains of human seasonal influenza A (H3N2) and swine influenza A (H1N1). During the influenza season, in adults hospitalized with HIV, the diagnostic possibilities should include influenza-like illnesses, eg, human parainfluenza virus types 3 and 4, human metapneumovirus, and pertussis. CASE REPORT: We present an adult with HIV, hospitalized for an influenza-like illness during influenza season. The differential diagnosis of CAP in this patient included influenza A and PCP. CONCLUSION: We report on an adult patient with HIV with CAP that mimicked influenza and PCP, and was attributable to RSV.

Renal transplant with bronchiolitis obliterans organizing pneumonia (BOOP) attributable to tacrolimus and herpes simplex virus (HSV) pneumonia.

BACKGROUND: Solid organ transplants (SOTs) may be complicated by a wide variety of infectious and noninfectious pulmonary disorders. Transplant patients receive immunosuppressive drugs to prevent rejection, but these drugs also predispose them to infection. Because immunosuppressive therapy impairs T-lymphocyte function, ie, cell-mediated immunity, such therapy, not surprisingly, predisposes patients to intracellular pulmonary pathogens. Community-acquired pneumonia (CAP) in patients with SOT usually involves one of the common typical or atypical bacterial CAP pathogens infecting immunocompetent hosts. The most frequent intracellular CAP pathogens in SOTs during immunosuppressive therapy are viral, eg, cytomegalovirus (CMV), respiratory syncytial virus (RSV), and herpes simplex virus (HSV). In addition, intracellular fungal pathogens are also common in patients with SOTs during immunosuppressive therapy, eg, Pneumocystis (carinii) jiroveci pneumonia (PCP). In addition, a variety of noninfectious disorders are not uncommon in patients with SOTs, including bronchiolitis obliterans organizing pneumonia (BOOP). Bronchiolitis obliterans organizing pneumonia may be associated with a variety of infectious agents, or may be attributable to drugs, including some immunosuppressive agents. METHODS: The clinical approach to CAP in patients with SOTs may be based on the appearance of the chest x-ray (CXR) or chest computed tomography scan, combined with the degree of hypoxemia (ie, the A-a gradient). Patients with SOTs and with a normal or nearly normal CXR and a high degree of hypoxemia (A-a gradient, >35) most often have an early viral pneumonia, eg, CMV or early PCP. If the CXR reveals bilateral patchy interstitial infiltrates and severe hypoxemia, the differential diagnosis is limited to moderate or severe viral pneumonia or PCP. Patients with SOTs and presenting with diffuse infiltrates and mild to moderate hypoxemia (A-a gradient, <35) are usually prone to noninfectious disorders, eg, congestive heart failure, pulmonary embolism, or drug-induced pneumonias. In patients with SOTs and CAP with focal or lobar infiltrates, the distribution of pathogens is the same as in immunocompetent hosts, ie, either a bacterial or atypical CAP pathogen. CASE REPORT AND CONCLUSION: A renal transplant patient developed bilateral patchy interstitial infiltrates with severe hypoxemia during hospitalization. The most likely differential diagnostic possibilities included PCP and BOOP. Bronchoalveolar lavage was performed to rule out PCP, and indicated cytopathic effects diagnostic of HSV pneumonia. Lung biopsy pathology confirmed the diagnosis of BOOP. In reviewing the patient's medications, we surmised that tacrolimus may have caused BOOP. The tacrolimus was discontinued, and the patient received acyclovir for HSV pneumonia.

Bronchoalveolar carcinoma (adenocarcinoma) mimicking recurrent bacterial community-acquired pneumonia (CAP).

Depending on the community-acquired pneumonia (CAP) pathogen, host factors, and immune status, CAPs resolve on chest x-rays at different rates. CAPs that resolve more slowly than expected, or not at all, are termed "slowly or non-resolving CAPs." In contrast, recurrent CAPs may be due to host defense defects (eg, multiple myelomas) or post-obstructive bronchogenic carcinomas. There are a variety of noninfectious disorders that may mimic CAPs on chest x-ray: alveolar hemorrhage, pulmonary drug reactions, radiation pneumonitis, Wegener's granulomatosis, bronchiolitis obliterans organizing pneumonia, bronchogenic carcinomas, and lymphomas. Noninfectious mimics of recurrent CAPs include congestive heart failure, pulmonary emboli, infarctions, sarcoidosis, and systemic lupus erythematosus pneumonitis. We present the case of a middle-aged man who presented with recurrent right middle lobe and right lower lobe CAPs. Diagnostic bronchoscopy showed no bronchial obstruction, but open lung biopsy showed bronchoalveolar carcinoma (well-differentiated adenocarcinoma). Bronchoalveolar carcinomas presenting as post-obstructive or recurrent CAPs are rare because the spread is along tissue planes and not endobronchially. The case described demonstrates a rare cause of bronchogenic carcinoma mimicking recurrent CAP.

Swine influenza (H1N1) pneumonia in hospitalized adults: chest film findings.

In patients with swine influenza (H1N1) pneumonia, the admission chest film is critical to rapidly detect simultaneous bacterial pneumonia due to Staphylococcus aureus or subsequent bacterial pneumonia due to Streptococcus pneumoniae or Haemophilus influenzae by the presence of focal infiltrates. Our objective was to characterize the chest film findings in 25 adults hospitalized with H1N1 pneumonia during the pandemic and detect focal infiltrates indicative of bacterial coinfection, that is, bacterial pneumonia. Chest films were obtained on admission, after 48 hours, and thereafter as indicated throughout hospitalization. Chest film findings were classified as no infiltrates, clear with accentuated bibasilar lung markings, or focal segmental/lobar infiltrates. The presence or absence of pleural effusion and cavitation was also noted. Admitted adults with H1N1 pneumonia had negative chest films or accentuated basilar lung markings. After 48 hours, 13% of patients developed patchy bilateral interstitial infiltrates. No patients had or subsequently developed focal segmental/lobar infiltrates indicative of bacterial community-acquired pneumonia during hospitalization. The most common chest film finding was no infiltrates or an accentuation of bibasilar lung markings in hospitalized adults with H1N1 pneumonia. No patients had focal segmental/lobar infiltrates indicative of superimposed bacterial community-acquired pneumonia.

Severe swine influenza A (H1N1) versus severe human seasonal influenza A (H3N2): clinical comparisons.

At the beginning of the swine influenza (H1N1) pandemic in the spring of 2009, there were still stories of human seasonal influenza A circulating in the New York area. Adult patients admitted with influenza-like illnesses (ILIs) (fever > 102°F, dry cough, and myalgias) presented diagnostic problems. First, clinicians had to differentiate ILIs from influenza, and then differentiate human seasonal influenza A from H1N1 in hospitalized adults with ILIs and negative chest films (no focal segmental/lobar infiltrates). Human seasonal influenza A was diagnosed by rapid influenza diagnostic tests (RIDTs), but H1N1 was often RIDT negative. Reverse transcriptase-polymerase chain reaction for H1N1 was restricted or not available. The Winthrop-University Hospital Infectious Disease Division developed clinical diagnostic criteria (a diagnostic weighted point score system) to rapidly and clinically diagnose H1N1 in patients with negative RIDTs. The point score system was modified and shortened for ease of use, that is, the diagnostic H1N1 triad (any 3 of 4) (ILI, see above) plus thrombocytopenia, relative lymphopenia, elevated serum transaminases, or an elevated creatine phosphokinase. Our clinical experience during the pandemic allowed us to develop the swine diagnostic H1N1 triad. In the process, similarities and differences between human seasonal influenza A and H1N1 were noted. We present 2 illustrative cases of severe influenza, one due to human seasonal influenza A and one due to H1N1, for clinical consideration reflective of our experiences early in the H1N1 pandemic in 2009.

Systemic lupus erythematosus (SLE) pneumonitis mimicking swine influenza pneumonia during the swine influenza (H1N1) pandemic.

BACKGROUND: We present a young woman with a negative medical history who presented with acute systemic lupus erythematosus (SLE) pneumonitis mimicking swine influenza (H1N1) pneumonia. Because this case occurred during the H1N1 pandemic, the initial diagnostic impression was of H1N1 pneumonia. METHODS: Although her clinical and laboratory findings were consistent with the diagnosis of H1N1 pneumonia, e.g., fever, sore throat, dry cough, arthralgias, myalgias, thrombocytopenia, relative lymphopenia, and elevated serum transaminases, some findings suggested an alternate diagnosis, e.g., leukopenia, a highly elevated erythrocyte sedimentation rate, highly elevated serum ferritin levels, elevated antinuclear antibody (ANA) levels, and double-stranded (DS) DNA titers. Her chest x-ray showed an accentuation of basilar lung markings, with a small pleural effusion similar to the chest x-ray findings of early H1N1 pneumonia. Initially, her headaches were thought to be related to central nervous system manifestations of H1N1. RESULTS: After laboratory test results demonstrated elevated ANA and anti-DS DNA titers, she was diagnosed with acute SLE pneumonitis. The take-home lesson for clinicians is that other infectious diseases, e.g., human parainfluenza virus or Legionnaires' disease, can mimic H1N1 pneumonia during an influenza pandemic. Excluding asthma, congestive heart failure, exacerbations of acute bronchitis, chronic obstructive pulmonary disorder, and pulmonary interstitial disease, noninfectious mimics of H1N1 are extremely rare. CONCLUSION: To the best of our knowledge, this is the first reported case of de novo SLE pneumonitis mimicking H1N1 pneumonia during the swine influenza pandemic.
