RESUMO

OBJECTIVE: The aim of this multicenter study in a large childhood-onset systemic lupus erythematosus (cSLE) population was to assess the herpes zoster infection (HZI) prevalence, demographic data, clinical manifestations, laboratory findings, treatment, and outcome. METHODS: A retrospective multicenter cohort study (Brazilian cSLE group) was performed in ten Pediatric Rheumatology services in São Paulo State, Brazil, and included 852 cSLE patients. HZI was defined according to the presence of acute vesicular-bullous lesions on erythematous/edematous base, in a dermatomal distribution. Post-herpetic neuralgia was defined as persistent pain after one month of resolution of lesions in the same dermatome. Patients were divided in two groups for the assessment of current lupus manifestations, laboratory findings, and treatment: patients with HZI (evaluated at the first HZI) and patients without HZI (evaluated at the last visit). RESULTS: The frequency of HZI in cSLE patients was 120/852 (14%). Hospitalization occurred in 73 (61%) and overlap bacterial infection in 16 (13%). Intravenous or oral aciclovir was administered in 113/120 (94%) cSLE patients at HZI diagnosis. None of them had ophthalmic complication or death. Post-herpetic neuralgia occurred in 6/120 (5%). After Holm-Bonferroni correction for multiple comparisons, disease duration (1.58 vs 4.41 years, p < 0.0001) was significantly lower in HZI cSLE patients compared to those without HZI. Nephritis (37% vs 18%, p < 0.0001), lymphopenia (32% vs 17%, p < 0.0001) prednisone (97% vs 77%, p < 0.0001), cyclophosphamide (20% vs 5%, p < 0.0001) and SLE Disease Activity Index 2000 (6.0 (0-35) vs 2 (0-45), p < 0.0001) were significantly higher in the former group. The logistic regression model showed that four independent variables were associated with HZI: disease duration < 1 year (OR 2.893 (CI 1.821-4.597), p < 0.0001), lymphopenia <1500/mm(3) (OR 1.931 (CI 1.183-3.153), p = 0.009), prednisone (OR 6.723 (CI 2.072-21.815), p = 0.002), and cyclophosphamide use (OR 4.060 (CI 2.174-7.583), p < 0.0001). CONCLUSION: HZI is an early viral infection in cSLE with a typical dermatomal distribution. Lymphopenia and immunosuppressive treatment seem to be major factors underlying this complication in spite of a benign course.

RESUMO

The aim of this study was to assess the prevalence of factors associated with oral colonization by Candida spp. in pediatric patients with AIDS. The sample comprised of 117 children. Clinical status, medicines in use, and laboratory findings were obtained from hospital records; sociodemographic data were given by relatives. A dental examination assessed the prevalence of dental caries. The prevalence of oral colonization by Candida was 62%. Only seven children presented clinical manifestation of oral candidosis despite their high viral load index and low-for-age CD4 count. Candida colonization was directly associated with frequent use of antibiotics (prevalence ratio [PR] = 1.44), sulfa drugs (PR = 1.23), alteration in the oral mucosa (PR = 1.55), and untreated dental caries (PR = 1.93). It was inversely associated with the use of antiretroviral therapies (PR = 0.65). Candida albicans was the most frequently detected species (80%); phenotypic tests did not detect C. dubliniensis strains. This study observed a low prevalence of Candida-related oral lesions in these patients, which is compatible with the hypothesis that antiretroviral medicines may have contributed to reducing oral manifestations from Candida infection. The high prevalence of Candida colonization in HIV+/AIDS children with untreated dental caries reinforces the importance of oral health care in interdisciplinary health units that assist these patients.

RESUMO

We assessed the risk factors associated with death in patients hospitalized for juvenile systemic lupus erythematosus (JSLE) and evaluated the autopsy reports. A total of 57,159 hospitalizations occurred in our institution from 1994 to 2003, 169 of them involving 71 patients with JSLE. The most recent hospitalization of these patients was evaluated. Patients were divided into two groups based on mortality during hospitalization: those who survived (N = 53) and those who died (N = 18). The main causes of hospitalization were JSLE activity associated with infection in 52% and isolated JSLE activity in 44%. Univariate analysis showed that a greater risk of death was due to severe sepsis (OR = 17.8, CI = 4.5-70.9), systemic lupus erythematosus disease activity index (SLEDAI) >or=8 (OR = 7.6, CI = 1.1-53.8), general infections (OR = 6.1, CI = 1.5-25), fungal infections (OR = 5.4, CI = 3.2-9), acute renal failure (OR = 5.1, CI = 2.5-10.4), acute thrombocytopenia (OR = 3.9, CI = 1.9-8.4), and bacterial infections (OR = 2.3, CI = 1.2-7.5). Stratified analysis showed that severe sepsis and SLEDAI >or=8 were not confounder variables. In the multivariate analysis, logistic regression showed that the only independent variable in death prediction was severe sepsis (OR = 98, CI = 16.3-586.2). Discordance between clinical diagnosis and autopsy was observed in 6/10 cases. Mortality of hospitalized JSLE patients was associated with severe sepsis. Autopsy was important to determine events not detected or doubtful in dead patients and should always be requested.

RESUMO

OBJECTIVE: The increasing number of women with AIDS in the state of São Paulo has lead to the implementation of a series of measures to reduce mother-to-child HIV transmission. The objective of this study was to evaluate these measures' deficiencies regarding coverage and quality of prenatal care in some HIV reference services in the state of São Paulo. METHODS: All HIV-positive women, aged 18 years or more, who gave birth in 1998 were interviewed when they came for a visit with an infectologist or a pediatrician in three cities (São Paulo, Santos and São José do Rio Preto) of the state of São Paulo. A structured questionnaire was applied. Prenatal care and time of their HIV infection diagnosis (before, during or after pregnancy) were assessed. RESULTS: Of 116 women interviewed, 109/116 (94%) had attended a prenatal care service during pregnancy, 64% had their first visit in the first trimester and 80% had 3 or more visits during pregnancy. The mean age of those who attended a prenatal service was 29.1 years, higher than those who did not attend any service (24.3 years). The HIV-positive status was known by 45%, 38% and 17% of the women before pregnancy, during pregnancy and after delivery, respectively. HIV testing was offered to 82% who did not know their serologic status, and among these, only 56% were informed about the importance of getting tested. The basic health care units (UBS) were less efficient in conveying information to the mothers about their children's infection risk (p=0.037) and their treatment needs (p=0.014). CONCLUSIONS: The main deficiencies identified were lack of HIV testing during pregnancy and inadequate information. Though basic health care units are the most important source of care for this population, its contribution to the understanding of risks and treatment needs was the most unsatisfactory.

RESUMO

Tuberculosis still occupies a remarkable place as a worldwide health problem, chiefly in emerging countries, like Brazil. The central nervous system (CNS) involvement by Mycobacterium tuberculosis is one of the most feared features of disease, because of its high morbidity and mortality. This study aimed to describe some epidemiological, clinical and laboratorial aspects of 52 children in a tertiary pediatric hospital with CNS tuberculosis. At diagnosis, the majority of patients showed low age, compromised nutritional status, previous contact with bacillary individuals, delayed or absent immunization, advanced neurological signs and compatible abnormalities in cerebrospinal fluid (CSF) analysis and in radiological findings. The etiologic agent was identified by staining methods or CSF and other fluids culturing in 40% of patients. In most cases, despite of suggestive clinical, epidemiological and laboratorial picture and feasibility of patients access to health care centres, therapy was started late.

RESUMO

Neurologic damage is usual after central nervous system (CSN) tuberculosis recovery. Treatment is long, difficult and prone to complications. Many factors are enrolled as prognostic determinants. This study aimed to describe the treatment and outcome of 52 children with CNS tuberculosis of a tertiary pediatric hospital. All of them received standard triple drug regimen, and 41 (78.8%) received corticosteroids as adjunctive therapy. Hydrocephalus was common (28 of 41 tested), but only 8 (15.4%) patients underwent ventricular shunt surgery. Hepatotoxicity to anti tuberculosis drugs occurred in 32 (61.5%) cases, but in only 3 (9.4%) drug substitution was necessary. There were 8 (15.4%) deaths and 24 (46.1%) cases developed neurologic damage after therapy. Patients who did not receive steroids during treatment and those with advanced neurological involvement at diagnosis showed a tendency to worse prognosis.

RESUMO

Poliomyelitis associated with live strain vaccine is defined as the paralytic form of the acute anterior poliomyelitis related to the vaccine strain. Since these strains behave similarly to the wild-type virus, we can differentiate, epidemiologically, two types of vaccine-associated poliomyelitis: cases in which the patient was vaccinated and cases in which the patient had had contact with vaccinated individuals. We herein present the case of an unvaccinated child, with a clinical picture of an acute anterior poliomyelitis associated with the live strain vaccine, whose brother received the Sabin vaccine 20 days before the onset of the symptoms. Vaccine strain of the type 3 poliovirus was isolated in fecal culture and a presented mutation in nucleotide 472 (C-->U) in the 5' non-coding region, which is strongly related to the higher strain virulence.

RESUMO

OBJECTIVES: A nutritional evaluation of infants born from HIV seropositive mothers was carried out during their follow up and diagnostic investigation. The energy balance (EB) of infected and noninfected children were compared. METHODS: The energy balance (intake energy, fecal energy, and resting energy expenditure) was prospectively determined by indirect calorimetry, considering 13 infants (6 girls and 7 boys) between 1 and 6 months of age, born from HIV positive mothers. This was made in two opportunities: before and after the diagnosis of the disease. A full nutritional assessment, including clinical examination and anthropometric measures (weight, height and skinfold thickness), was also determined in these two opportunities. After the definite diagnosis, the infants were finally assembled in 2 different groups: infected (5 in 13) and noninfected (8 in 13). The children were monthly submitted to clinical evaluations and orientation, during all the study. RESULTS: By analyzing the anthropometric measures of the two groups, it was observed that the infected group had malnutritional manifestations since the first evaluation. The resting energy expenditure (kcal/kg/dia) of the infected group was higher than that of the noninfected group: 64.5-/+16.8 vs 48.0-/+5.7 (p<0.05) at the first evaluation and 68.0-/+11.7 vs 51.8-/+3.1 (p<0.05) at the second, respectively. CONCLUSION: The higher resting energy expenditure of the children in the infected group might be the cause of the protein energy malnutrition during the asymptomatic phase when the diagnosis was uncertain.
