Clinical laboratory and dispersion pattern of COVID-19 in a family cluster in the social-distancing period.

INTRODUCTION: Since the first reports of coronavirus disease 2019 (COVID-19) in December 2019, the disease has spread worldwide. Different social isolation strategies have been adopted to reduce community transmission, but few studies have evaluated the pattern of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection in a family cluster during periods of isolation. We report an outbreak in 24 members of a family cluster during a period of social distancing. METHODOLOGY: We carried out an observational descriptive study of a family cluster infected with SARS-CoV-2 in Pernambuco, Northeast Brazil. Laboratory confirmation included RT-PCR of nasopharyngeal samples or IgM or IgG serology. RESULTS: The attack rates were 75% (19/24) based on laboratory-confirmed cases and 87.5% (21/24) including probable cases. The time of spread was 17 days from the first case. All patients had mild symptoms, requiring no hospitalization, and none of them died. The frequency of symptomatic, laboratory-confirmed patients was higher among adults (94%) than among children (50%); the paediatric age group also had a higher frequency of exposed individuals who remained negative for infection. Ground-glass opacities on chest computed tomography were present in all patients with reported dyspnoea. CONCLUSION: This study highlights a high risk of intrahousehold transmission from an index case, suggesting the need for (I) specific guidelines during periods of social distancing, (II) minimization of external exposures and, above all, (III) adoption of strict quarantine measures for suspected cases and family members to prevent outbreaks from spreading.

Update on the treatment of musculoskeletal manifestations in chikungunya fever: a guideline.

Since the emergence of the chikungunya virus in Brazil in 2014, more than 700,000 cases have been reported throughout the country, corresponding to one-third of all cases reported in the Americas. In addition to its high attack rates, resulting in hundreds of thousands of cases, the disease has high chronicity rates with persistent joint manifestations for more than 3 months, which can spread to more than half of the patients affected in the acute phase. Pain associated with musculoskeletal manifestations, often disabling, has an effect on patients' quality of life at different stages of the disease. Currently, the challenge faced by specialists is identifying the best therapy to be instituted for symptom relief despite the limited number of published intervention studies. In 2016, a multidisciplinary group published pharmacological treatment protocols for pain in patients with chikungunya, which was incorporated into the guidelines for clinical management of the Brazilian Ministry of Health in 2017; in that same year, a consensus was published by the Brazilian Society of Rheumatology about diagnosis and treatment. After 5 years of experience with chikungunya epidemics, in 2019, specialists involved in the protocols of the Brazilian Society of Rheumatology and Brazilian Ministry of Health prepared an update with the main objective of developing flowcharts for the therapeutic approach of musculoskeletal manifestations in adult patients to enable specialists at different levels of healthcare to spread and apply this guideline in a systematic and simplified manner.

The microcephaly epidemic and Zika virus: building knowledge in epidemiology. / Epidemia de microcefalia e vírus Zika: a construção do conhecimento em epidemiologia.

In August 2015, pediatric neurologists at public hospitals in Recife, Pernambuco State, Brazil, observed an increase in the number of disproportional microcephaly cases associated with other congenital anomalies. The fact caused social commotion and mobilization of the academic community and led the Brazilian Ministry of Health to declare a national public health emergency, followed by the declaration of a Public Health Emergency of International Concern by the World Health Organization. The hypothesis for the phenomenon was congenital Zika virus (ZIKV) infection, based on spatial-temporal correlation and the clinical-epidemiological characteristics of the two epidemics. Further evidence accumulated, and within the scope of epidemiologial reasoning fulfilled criteria that gave support to the hypothesis. The plausibility of the hypothesis is based on the neurotropism of ZIKV, demonstrated in animals, affecting neural progenitors in the developing brain, and in humans, due to neurological complications in adults following infection. Isolation of viral RNA and antigens in the amniotic fluid of infected mothers and in brains of newborns and fetuses with microcephaly further demonstrated the consistency of the hypothesis. The criterion of temporality was met by identifying adverse pregnancy outcomes in a cohort of mothers with a history of rash and positive ZIKV serology. Finally, the first case-control study demonstrated a strong association between microcephaly and congenital ZIKV infection. The knowledge built with the epidemiological paradigm was supported by the scientific community, thereby establishing the consensus for a causal relationship between ZIKV and the microcephaly epidemic.

Em agosto de 2015, neuropediatras de hospitais públicos do Recife, Pernambuco, Brasil, observaram um aumento do número de casos de microcefalia desproporcional associado a anomalias cerebrais. Esse fato gerou comoção social, mobilização da comunidade acadêmica e levou o Ministério da Saúde a decretar emergência de saúde pública nacional, seguida pela declaração de emergência de saúde pública de interesse internacional da Organização Mundial da Saúde. A hipótese formulada para o fenômeno foi a infecção congênita pelo vírus Zika (ZIKV), com base na correlação espaço-temporal e nas características clínico-epidemiológicas das duas epidemias. Evidências se acumularam e no âmbito do raciocínio epidemiológico preencheram critérios que deram sustentação à hipótese. Sua plausibilidade está ancorada no neurotropismo do ZIKV demonstrado em animais, atingindo neurônios progenitores do cérebro em desenvolvimento, e em seres humanos devido às complicações neurológicas observadas em adultos após a infecção. O isolamento do RNA e antígenos virais no líquido amniótico de mães infectadas e em cérebros de neonatos e fetos com microcefalia contribuíram para demonstrar a consistência da hipótese. O critério de temporalidade foi contemplado ao se identificar desfechos desfavoráveis em uma coorte de gestantes com exantema e positivas para o ZIKV. Finalmente, o primeiro estudo caso-controle conduzido demonstrou existir uma forte associação entre microcefalia e infecção congênita pelo ZIKV. O conhecimento construído no âmbito do paradigma epidemiológico recebeu a chancela da comunidade científica, construindo o consenso de uma relação causal entre o ZIKV e a epidemia de microcefalia.

HLA-G is expressed in intestinal samples of ulcerative colitis and Crohn's disease patients and HLA-G5 expression is differentially correlated with TNF and IL-10 cytokine expression.

HLA-G is an immunomodulatory molecule that can be produced by epithelial cells. Considering that TNF and IL-10 participate in bowel inflammatory disorders and that both cytokines modulate HLA-G, we evaluated HLA-G, TNF and IL-10 mRNA expression by qPCR and HLA-G protein levels by immunohistochemistry in two intestinal samples exhibiting different degree of inflammation within a patient suffering from Crohn's disease (CD) or ulcerative colitis (UC). Tissue HLA-G5 (P < 0.0001), TNF (P = 0.0004) and IL-10 (P = 0.0169) mRNA expression levels were higher in intestinal areas exhibiting intense inflammation compared to areas of low inflammation, and HLA-G protein levels were not associated with degree of mucosal inflammation. In CD, the expression of TNF was correlated with IL-10 in low inflamed areas, exhibiting a TNF:IL-10 ratio = 3, but in inflamed areas the ratio increased to 9-folds. In UC, the expression of TNF was correlated to IL-10, irrespective of the inflammation grade, with little variation of the TNF:IL-10 ratio in the various inflamed areas. TNF and IL-10 expression was correlated with HLA-G5 expression in mild inflamed areas. Both CD and UC samples exhibited gene and protein expression of HLA-G; and the HLA-G5 expression is differentially correlated with TNF and IL-10 levels depending on the type of the underlying inflammatory bowel disorder.

Alert: Severe cases and deaths associated with Chikungunya in Brazil.

Since the detection of the Chikungunya virus in America in 2013, two million cases of the disease have been notified worldwide. Severe cases and deaths related to Chikungunya have been reported in India and Reunion Island, estimated at 1 death per 1,000 inhabitants. Joint involvement in the acute and chronic phase is the main clinical manifestation associated with Chikungunya. The severity of the infection may be directly attributable to viral action or indirectly, owing to decompensation of preexisting comorbidities. In Brazil, the virus was identified in 2014, and recently, there has been a significant increase in the number of deaths caused by the Chikungunya virus infection, especially in Pernambuco. However, the numbers of fatalities are probably underreported, since for many cases, the diagnosis of Chikungunya infection may not be considered, for deaths by indirect causes. An increase in the mortality rate within months of epidemic occurrence, compared to previous years has also been reported and may be associated with Chikungunya virus infection. An in-depth investigation of reported mortality in Brazil is necessary, to measure the actual impact of the deaths, thereby, allowing the identification of possible causes. This will alert professionals about the risks, and hence, enable creation of protocols that target reducing mortality.

Cardiac tamponade in a patient with severe dengue fever.

A 26-year-old postpartum female presented with symptoms characteristic of dengue fever on the 16th day of puerperium. On the third day of the illness, the patient presented a clinical picture consistent with shock. Tests determined primary infection with dengue virus serotype 2. Cardiac tamponade was confirmed by echocardiography. This rare manifestation is described in a patient without any associated comorbidity.

Increased number of deaths during a chikungunya epidemic in Pernambuco, Brazil.

In early 2016, it was suspected that there were more deaths in Pernambuco than in previous years during an epidemic of chikungunya. This study tested whether there was an increased number of deaths and, if so, whether this increase could be related to a chikungunya epidemic. Indeed, there was an increase of 4235 deaths in 2016 compared to the average of the four previous years, and the highest differences were found during the peak period of the epidemic. It was evident that not all of these deaths could be attributed to complications of chikungunya. However, considering the temporal overlap, some of these deaths may have been caused by the aggravation of pre-existing comorbidities or complications caused directly by chikungunya virus infection.

Encephalitis associated with inappropriate antidiuretic hormone secretion due to chikungunya infection in Recife, State of Pernambuco, Brazil.

The symptoms of chikungunya virus (CHIKV) infection include fever, headache, muscle aches, skin rash, and polyarthralgia, characterized by intense pain, edema, and temporary functional impairment. This is the first report of encephalitis caused by CHIKV infection associated with an atypical presentation of syndrome of inappropriate antidiuretic hormone secretion, evolving to cognitive impairment and apraxia of speech.

Pharmacologic management of pain in patients with Chikungunya: a guideline.

From the arrival of Chikungunya virus in the Americas in 2013 until March 2016, approximately two million cases of the disease have been reported. In Brazil, the virus was identified in 2014 and thousands of people have been affected. The disease has high attack rates, infecting 50% of a population within a few months. Approximately 50% of infected people develop chronic symptoms lasting for months or years. Joint involvement is the main clinical manifestation of Chikungunya. It is characterized by swelling and intense pain that is poorly responsive to analgesics, both in the acute and chronic phase of the disease. This significantly compromises quality of life and may have immeasurable psychosocial and economic repercussions, constituting therefore, a serious public health problem requiring a targeted approach. Physicians are often not familiar with how to approach the management of pain, frequently prescribing limited analgesics, such as dipyrone, in sub-therapeutic doses. In addition, there are few published studies or guidelines on the approach to the treatment of pain in patients with Chikungunya. Some groups of specialists from different fields have thus developed a protocol for the pharmacologic treatment of Chikungunya-associated acute and chronic joint pain; this will be presented in this review.

One year after the Zika virus outbreak in Brazil: from hypotheses to evidence.

Zika virusis an arbovirus of the Flaviviridae family with two major strains, an Asian and an African strain. The main vectors involved in the transmission of Zika virus are the Aedes aegypti and Aedes albopictus mosquitoes. Despite its identification, discovered in 1947 in the Zika forest in Uganda, only isolated and sporadic occurrences of human infection were reported within a largely asymptomatic proportion of individuals. The first reported outbreak occurred in 2007 in the Yap Island, which belongs to the Federated States of Micronesia in the Pacific Ocean, and in French Polynesia, where high attack rates occurred and the first cases of associated Guillain-Barré syndrome were reported. From November 2014 to early 2015, the Northeast states of Brazil reported the first outbreaks of Zika virus infection, with laboratory confirmation of Zika virus circulation in April 2015. In the second quarter of 2015, the association between Zika virus infection and neurological symptoms was confirmed in adults. Moreover, in October 2015 a novel suspicion was raised based on clinical and epidemiological observations: that an association between Zika virus infection and neonatal microcephaly may exist. A year after the first reports on Zika virus in Brazil, many hypotheses and much evidence on the patterns of involvement of the disease and its complications have been produced, both in this country and others; other hypotheses still need to be clarified. This review is a synthesis of a new chapter in the history of medicine; it outlines the main results produced.

Zika in Pernambuco: rewriting the first outbreak.

INTRODUCTION:: A Zika virus epidemic was registered in 2015 in Northeast Brazil. In the State of Pernambuco, thousands of classical cases transpired, and in the following months, neurological disturbances in adults and microcephaly in newborns emerged as complications. After the peak of the epidemic, the official system reported only four cases of Zika virus but over 100,000 cases of dengue virus. The vigilance system was unable to retrospectively estimate cases or to issue an alert to officially notified cases with possible inconsistence concerning specific arbovirosis diagnoses. METHODS:: To evaluate the frequency of different arbovirosis diagnoses based on clinical-epidemiologic criteria, from January to April 2015, we conducted a hospital-based cross-sectional study retrospectively analyzing suspected cases of arbovirosis. RESULTS:: Of 1 , 046 total suspected cases of arbovirus, 895 (86%) were classified as probable Zika virus cases, and 151 (14%) as probable dengue virus cases. The most frequent manifestations in probable Zika virus cases were exanthema (100%), pruritus (50.7%), fever (20.4%) and arthralgia (27.7%). CONCLUSIONS:: In contrast to the official data, during the peak months of the arbovirosis epidemic of 2015, most cases were compatible with Zika virus infections. Hospital-based studies, although retrospective and based on secondary data from clinical files, might provide a better estimate of the number of cases relative to currently available data, if derived from several urgent care units of representative areas of a city or state.This would partially retrospectively correct some inconsistences regarding official notifications.
