Recidivas de casos de hanseníase no estado de Mato Grosso

OBJETIVO: Comparar as novas entradas por recidiva de hanseníase em unidades básicas de saúde (UBS) e em unidades especializadas (UE) no estado de Mato Grosso. MÉTODOS: Estudo transversal com base em todos os registros (N = 323) de recidivas de hanseníase do Sistema de Informação de Agravos de Notificação (Sinan) de 2004 a 2006, notificados no estado de Mato Grosso. Os casos diagnosticados foram comparados quanto ao sexo, idade, aspectos clínico-laboratoriais e distribuição geográfica nos municípios. Para a comparação e cálculo das proporções das variáveis utilizou-se o teste qui-quadrado ao nível de significância de 5%. RESULTADOS: Das novas entradas de recidiva, 20% foi confirmado nas UE e 80% em UBS; entretanto, a maioria dos diagnósticos em UBS tinham baciloscopia negativa (÷² =12,34; p = 0,002). O sexo masculino atingiu 71%, com idade média de 43 anos. Não foi observada diferença nos percentuais das entradas entre as unidades de saúde segundo forma clínica, classificação operacional e grau de incapacidade física. Do total de municípios do estado, 64,7% apresentou recidiva, com percentual entre 6% e 20% de todas as entradas. CONCLUSÕES: As novas entradas de casos de recidiva em Mato Grosso são influenciadas pelos diagnósticos feitos em UBS, sugerindo que há deficiência na rede de serviços de saúde em reconhecer casos de recidiva.

Mortalidade por doenças cardiorrespiratórias em idosos no estado de Mato Grosso, 1986 a 2006

OBJETIVO: Descrever a evolução temporal da mortalidade por doenças cardiorrespiratórias em idosos. MÉTODOS: Estudo epidemiológico descritivo com delineamento ecológico de séries temporais realizado no estado do Mato Grosso, de 1986 a 2006. Foram utilizados dados sobre doenças dos aparelhos respiratório e circulatório obtidos do Sistema de Informação sobre Mortalidade do Ministério da Saúde. Modelos de regressão linear simples foram ajustados para avaliar a tendência das taxas específicas de mortalidade por grupos específicos de idade (60 a 69, 70 a 79 e 80 ou mais anos) e sexo. RESULTADOS: Houve aumento na proporção de óbitos por doenças respiratórias e diminuição por doenças cardiovasculares. Na comparação de taxas entre os sexos, as mulheres apresentaram taxas 15% menores para as causas cardiovasculares e taxas similares ao sexo masculino para as causas respiratórias. Foi observada taxa elevada de mortalidade por doenças respiratórias e cardiovasculares, com importante tendência de incremento entre os grupos mais longevos. Em idosos com idade > 80 anos o aumento anual médio na taxa de mortalidade por doenças respiratórias foi de 1,99 óbitos e de 3,43 por doenças do aparelho circulatório. CONCLUSÕES: O estado de Mato Grosso apresenta elevada taxa de mortalidade por doenças respiratórias e cardiovasculares em idosos, com importante tendência de incremento entre os grupos mais longevos.

Infecção pelo vírus da hepatite C em gestantes em Mato Grosso do Sul, 2005-2007

O estudo teve por objetivo estimar a prevalência da infecção e genótipo do vírus da hepatite C (HCV), bem como determinar a subnotificação de casos. O total de 115.386 gestantes atendidas pelo Programa Estadual de Proteção à Gestante de Mato Grosso do Sul foi submetido à coleta de sangue para a detecção de anti-HCV, de 2005 a 2007. A prevalência da infecção pelo HCV foi de 1,07 casos/1.000. As amostras positivas foram submetidas à detecção do HCV-RNA e genotipadas. O genótipo 1 foi encontrado em 73% das amostras, 24,3% pertenciam ao genótipo 3 e 2,7% ao genótipo 2. A subnotificação de casos de hepatite C foi de 35,5%.

Desigualdades sociais e tuberculose: análise segundo raça/cor, Mato Grosso do Sul

OBJETIVO Analisar características sociodemográficas e clínico-epidemiológicas dos casos de tuberculose e fatores associados ao abandono e ao óbito na vigência do tratamento. MÉTODOS Estudo epidemiológico baseado em dados notificados de tuberculose em indígenas e não indígenas, segundo raça/cor, em Mato Grosso do Sul, entre 2001 e 2009. Realizou-se análise descritiva dos casos de acordo com as variáveis sexo, faixa etária, zona de residência, exames empregados para o diagnóstico, forma clínica, tratamento supervisionado e situação de encerramento, segundo raça/cor. Utilizou-se análise univariada e múltipla por meio de regressão logística para identificar preditores de abandono e óbito, e odds ratio como medida de associação. Foi construída série histórica de incidência, segundo raça/cor. RESULTADOS Registraram-se 6.962 casos novos de tuberculose no período, 15,6% entre indígenas. Houve predomínio em homens e adultos (20 a 44 anos) em todos os grupos. A maior parte dos doentes indígenas residia na zona rural (79,8%) e 13,5% dos registros nos indígenas ocorreram em < 10 anos. A incidência média no estado foi 34,5/100.000 habitantes, 209,0; 73,1; 52,7; 23,0 e 22,4 entre indígenas, amarelos, pretos, brancos e pardos, respectivamente. Doentes de 20 a 44 anos (OR = 13,3; IC95% 1,9;96,8), do sexo masculino (OR = 1,6; IC95% 1,1;2,3) e de raça/cor preta (OR = 2,5; IC95% 1,0;6,3) mostraram associação com abandono de tratamento, enquanto doentes > 45 anos (OR = 3,0; IC95% 1,2;7,8) e com a forma mista (OR = 2,3; IC95% 1,1;5,0) apresentaram associação com óbito. Apesar de representarem 3,0% da população, os indígenas foram responsáveis por 15,6% das notificações no período. CONCLUSÕES Houve importantes desigualdades em relação ao adoecimento por tuberculose entre as categorias estudadas. As incidências nos indígenas foram consistentemente maiores, chegando a exceder em mais de seis vezes as médias nacionais. Entre pretos e pardos, piores resultados no tratamento foram observados, pois apresentaram chance de abandono duas vezes maior que os indígenas. O mau desempenho do programa também esteve fortemente associado ao abandono e ao óbito. Acredita-se que, enquanto não se reduzir a pobreza, as desigualdades nos indicadores em saúde permanecerão.

Conjuntivite hemorrágica aguda, em Cuiabá, Mato Grosso, Brasil, 1983

Foi feita investigação de natureza etiológica clínica e laboratorial durante uma epidemia de conjuntivite hemorrágica aguda (CHA), ocorrida em Cuiabá, MT durante os meses de dezembro de 1982 e fevereiro de 1983; atendidos 68 pacientes e colhidos espécimes da conjuntiva, orofaringe e soro. Em 28 pares de soros foram realizados testes de neutralização em tubos de cultura de tecidos para o enterovirus 70 (EV 70) e fixaço do complemento para os adenovirus. Os resultados revelaram conversão sorológica de 89,3% (25 pares de soro) para o EV 70. A Secretaria de Saúde do Estado do Mato Grosso estima que aproximadamente 70% da população tenha sido atingida durante o surto. Não foram observadas evidências de comprometimento neurológico em pacientes de conjuntivite, durante ou logo após o surto.

Study of 30 cases of histoplasmosis observed in the Mato Grosso do Sul State, Brazil

Thirty cases of histoplasmosis observed at the University Hospital of the Federal University of Mato Grosso do Sul (HU-UFMS) from January 1998 to December 2005 are reported. Most (83.3%) of the patients were men, average 33.4 years old, 63.3% of them were born and living in Mato Grosso do Sul and 83.3% presented AIDS as an underlying disease. In almost all cases (96.7%) the disease occurred in its disseminated form and the most frequent clinical manifestations were: fever (83.3%), weight loss (70.0%), cough (63.3%), hepatomegaly and splenomegaly (40.0%), and lymph node enlargement (36.7%). The laboratory diagnosis was obtained in 29 patients by isolation of Histoplasma capsulatum from various clinical specimens cultivated in Sabouraud dextrose and brain heart infusion agar and in 16 patients the fungus was observed by direct microscopy of Giemsa-stained smears. The observed mortality was 40%. This is the first report in the literature of the occurrence of histoplasmosis in Mato Grosso do Sul State.

Natural infection of phlebotomines (Diptera: Psychodidae) in a visceral-leishmaniasis focus in Mato Grosso do Sul, Brazil

The main purpose of this study was to investigate natural infection by Leishmania in phlebotomine females in a visceral-leishmaniasis focus in Antonio João county in Mato Grosso do Sul State, Brazil. Between June and October 2003, the digestive tracts of 81 females captured in Aldeia Campestre, Aldeia Marangatu and Povoado Campestre were dissected. The females were separated by species, location, area and date of capture into 13 groups and kept in ethanol 70%. To identify the Leishmania species using the PCR technique, amplifications of the ribosomal-DNA (rDNA) and mini-exon genes were analyzed. Of the 81 specimens, 77 (95%) were Lutzomyia longipalpis, making this the most common species; only one specimen of each of the species Brumptomyia avellari, Evandromyia cortelezzii, Evandromyia lenti and Nyssomyia whitmani was found. Trypanosomatids were identified in eight of the nine groups of Lutzomyia longipalpis (10.39%) one group from Aldeia Campestre, one from Aldeia Marangatu and six from Povoado Campestre; of the eight groups, one from Aldeia Marangatu and another, with promastigotes forms also confirmed by dissection (1.23%) from Povoado Campestre, were identified by PCR as Leishmania chagasi (2.6%). The other groups gave negative results. These findings indicate that there is a high risk of leishmaniasis transmission in this area.

Distribution of phlebotomine sandflies (Diptera: Psychodidae) of medical importance in Mato Grosso State, Brazil

Intense environmental impacts, causing alterations of the natural habitats of fauna, including those of sandfly disease vectors are observed in Mato Grosso State, Central Brazil. Entomologic survey of phlebotomines was based on light trap and was carried out by entomological nucleus of the FUNASA and SES in the period between 1996 and 2001. Eighty eight species were identified, including the following sandflies with medical importance to leishmaniasis: Lutzomyia amazonensis, L. anduzei, L. antunesi, L. ayrozai, L. carrerai carrerai, L. complexa, L. cruzi, L. flaviscutellata, L. intermedia, L. longipalpis, L. migonei, L. paraensis, L. ubiquitalis, L. whitmani and L. yuilli yuilli. Most sandflies of medical importance occurred in the Amazon forest and savannah. L. longipalpis and L. cruzi had high densities in the savannah region. L. flaviscutellata is predominating in both the Amazon forest and the savannah region. L. whitmani and L. antunesi were sampled in the Amazon forest, savannah and marsh land.

Clinical and epidemiological features of 123 cases of cryptococcosis in Mato Grosso do Sul, Brazil

To identify the clinical and epidemiological profile of cryptococcosis diagnosed at the University Hospital of the Federal University of Mato Grosso do Sul, Brazil, medical records of 123 patients admitted from January 1995 to December 2005 were analyzed. One hundred and four cases (84.5%) had HIV infection, six (4.9%) had other predisposing conditions and 13 (10.6%) were immunocompetent. Male patients predominated (68.3%) and their age ranged from 19 to 69 years (mean: 35.9). Most patients (73.2%) were born and lived lifelong in the state of Mato Grosso do Sul. Involvement of the central nervous system occurred in 103 patients (83.7%) and headache and vomiting were the most frequent symptoms. In 77 cases it was possible to identify the Cryptococcus species: 69 (89.6%) C. neoformans and eight (10.4%) C. gattii. Amphotericin B was the drug of choice for treatment (106/123), followed by fluconazole in 60% of cases. The overall lethality rate was 49.6%, being 51% among the HIV infected patients and 41.2% among the non-HIV infected (p > 0.05). Although cryptococcosis exhibited in our region a similar behavior to that described in the literature, the detection of an important rate of immunocompetent individuals and five C. gattii cryptococcosis in HIV-infected patients is noteworthy.

Candida bloodstream infection: data from a teaching hospital in Mato Grosso do Sul, Brazil

The incidence of Candida bloodstream infection has increased over the past years. In the Center-West region of Brazil, data on candidemia are scarce. This paper reports a retrospective analysis of 96 cases of Candida bloodstream infection at a Brazilian tertiary-care teaching hospital in the state of Mato Grosso do Sul, from January 1998 to December 2006. Demographic, clinical and laboratory data were collected from medical records and from the hospital's laboratory database. Patients' ages ranged from three days to 92 years, with 53 (55.2%) adults and 43 (44.8%) children. Of the latter, 25 (58.1%) were newborns. The risk conditions most often found were: long period of hospitalization, utilization of venous central catheter, and previous use of antibiotics. Fifty-eight (60.4%) patients died during the hospitalization period and eight (13.7%) of them died 30 days after the diagnosis of candidemia. Candida albicans (45.8%) was the most prevalent species, followed by C. parapsilosis (34.4%), C. tropicalis (14.6%) and C. glabrata (5.2%). This is the first report of Candida bloodstream infection in the state of Mato Grosso do Sul and it highlights the importance of considering the possibility of invasive Candida infection in patients exposed to risk factors, particularly among neonates and the elderly.

Fungal agents in different anatomical sites in Public Health Services in Cuiabá, state of Mato Grosso, Brazil

INTRODUCTION: A contribution to the regional epidemiological profile of the most common fungal agents in Public Health Services in Cuiabá, state of Mato Grosso, including university hospitals and polyclinics. METHODS: Clinical specimens (n = 1,496) from 1,078 patients were collected, submitted to direct mycological exam (potash or stick tape method) and cultured in specific mediums. Dermatophytic and non-dermatophytic agents were identified according to micromorphology (Ridell technique). RESULTS: The majority of the 1,496 specimens were skin (n = 985) and nail exams (n = 472). Of the 800 positive cultures, 246 (30.8%) corresponded to dermatophytes and 336 (42%) to yeasts of the genus Candida, 190 (23.7%) to other yeasts, 27 (3.4%) to non-dermatophytic filamentous fungi and one (0.1%) the agent of subcutaneous mycosis. Lesions considered primary occurred in greater numbers (59.5%) than recurrent lesions (37.4%), with a greater concentration of positivity occurring on the arms and legs. CONCLUSIONS: Comorbidities, allergies and diabetes mellitus were conditions associated with greater positivity in direct mycological exams and cultures. Positive culture was considered a definitive diagnosis of fungal infection and confirmed 47.8% of diagnostic hypotheses.

FIRST REPORT ON Cryptococcus neoformans IN PIGEON EXCRETA FROM PUBLIC AND RESIDENTIAL LOCATIONS IN THE METROPOLITAN AREA OF CUIABÁ, STATE OF MATO GROSSO, BRAZIL

SUMMARYCryptococcosis is a severe systemic mycosis caused by two species of Cryptococcus that affect humans and animals: C. neoformans and C. gattii. Cosmopolitan and emergent, the mycosis results from the interaction between a susceptible host and the environment. The occurrence of C. neoformanswas evaluated in 122 samples of dried pigeon excreta collected in 49 locations in the City of Cuiabá, State of Mato Grosso, Brazil, including public squares (n = 5), churches (n = 4), educational institutions (n = 3), health units (n = 8), open areas covered with asbestos (n = 4), residences (n = 23), factory (n = 1) and a prison (n = 1). Samples collected from July to December of 2010 were seeded on Niger seed agar (NSA). Dark brown colonies were identified by urease test, carbon source assimilation tests and canavanine-glycine-bromothymol blue medium. Polymerase chain reaction primer pairs specific for C. neoformans were also used for identification. Cryptococcus neoformans associated to pigeon excreta was isolated from eight (6.6%) samples corresponding to six (12.2%) locations.Cryptococcus neoformans was isolated from urban areas, predominantly in residences, constituting a risk of acquiring the disease by immunocompromised and immunocompetent individuals.

DECREASING PREVALENCE OF THE ACUTE/SUBACUTE CLINICAL FORM OF PARACOCCIDIOIDOMYCOSIS IN MATO GROSSO DO SUL STATE, BRAZIL

With the objective to evaluate the behavior of paracoccidioidomycosis in the last three decades, clinical and epidemiological data of 595 patients admitted to clinical services of the Federal University of Mato Grosso do Sul from 1980 to 2009 were investigated. Gender, age distribution, clinical form, comorbidity with tuberculosis or AIDS, and mortality were compared by decades of clinical admission. It was shown that during the three decades there was a decrease in women percentage, and the same manner occurred a reduction in participants in the age group of 20 to 39 years. Moreover, the acute/subacute forms have been diminished in the period. These fluctuations are closely related and can be simultaneously analyzed. Increased AIDS co-infection prevalence from the first to the second decade was also revealed, coinciding with the appearance of the retroviral epidemic and stabilizing during the third decade. No change in the tuberculosis co-infection rate was observed (overall = 6.9%). It reinforces the importance of this co-morbidity. The overall mortality rate remained steady at 6.7%, not varying significantly from one decade to another. The persistent mortality rate calls attention to the importance of this neglected disease.

SEROLOGICAL MARKERS OF VIRAL, SYPHILITIC AND TOXOPLASMIC INFECTION IN CHILDREN AND TEENAGERS WITH NEPHROTIC SYNDROME: CASE SERIES FROM MATO GROSSO STATE, BRAZIL

Some infections can be the cause of secondary nephrotic syndrome. The aim of this study was to describe the experience of a Renal Disease Reference Clinic from Central Brazil, in which serological markers of some infectious agents are systematically screened in children with nephrotic syndrome. Data were obtained from the assessment of medical files of all children under fifteen years of age, who matched nephrotic syndrome criteria. Subjects were tested for IgG and IgM antibodies against T. gondii and cytomegalovirus; antibodies against Herpes simplex, hepatitis C virus and HIV; and surface antigen (HBsAg) of hepatitis B virus. The VDRL test was also performed. 169 cases were studied. The median age on the first visit was 44 months and 103 (60.9%) patients were male. Anti-CMV IgG and IgM were found in 70.4% and 4.1%, respectively. IgG and IgM against Toxoplasma gondii were present in 32.5% and 5.3%, respectively. Two patients were positive for HBsAg, but none showed markers for HIV, hepatitis C, or Treponema pallidum. IgG and IgM against herpes simplex virus were performed on 54 patients, of which 48.1% and 22.2% were positive. IgM antibodies in some children with clinical signs of recent infection suggest that these diseases may play a role in the genesis of nephrotic syndrome.
