Vancomycin resistance has no influence on outcomes of enterococcal bacteriuria

Background Infections with vancomycin-resistant enterococci (VRE) are a growing concern in hospitals. The impact of vancomycin resistance in enterococcal urinary tract infection is not well-defined. Aim To describe the epidemiology of enterococcal bacteriuria in a hospital and compare the clinical picture and patient outcomes depending on vancomycin resistance. Methods This was a 6-month prospective cohort study of hospital patients who were admitted with or who developed enterococcal bacteriuria in a 1250-bed tertiary care hospital. We examined clinical presentation, diagnostic work-up, management, and outcomes. Findings We included 254 patients with enterococcal bacteriuria; 160 (63%) were female and median age was 65 years (range: 17–96). A total of 116 (46%) bacteriurias were hospital-acquired and 145 (57%) catheter-associated. Most patients presented with asymptomatic bacteriuria (ASB) (119; 47%) or pyelonephritis (64; 25%); 51 (20%) had unclassifiable bacteriuria and 20 (8%) had cystitis. Secondary bloodstream infection was detected in 8 (3%) patients. Seventy of 119 (59%) with ASB received antibiotics (mostly vancomycin). There were 74 (29%) VRE bacteriurias. VRE and vancomycin-susceptible enterococci (VSE) produced similar rates of pyelonephritis [19 (25%) vs 45 (25%); P = 0.2], cystitis, and ASB. Outcomes such as ICU transfer [10 (14%) VRE vs 17 (9%) VSE; P = 0.3], hospital length of stay (6.8 vs 5.0 days; P = 0.08), and mortality [10 (14%) vs 13 (7%); P = 0.1] did not vary with vancomycin susceptibility. Conclusions Vancomycin resistance did not affect the clinical presentation nor did it impact patient outcomes in this cohort of inpatients with enterococcal bacteriuria. Almost half of our cohort had enterococcal ASB; more than 50% of these asymptomatic patients received unnecessary antibiotics. Antimicrobial stewardship efforts should address overtreatment of enterococcal bacteriurias.

Patient characteristics but not virulence factors discriminate between asymptomatic and symptomatic E. coli bacteriuria in the hospital

Background Escherichia coli is a common cause of asymptomatic and symptomatic bacteriuria in hospitalized patients. Asymptomatic bacteriuria (ASB) is frequently treated with antibiotics without a clear indication. Our goal was to determine patient and pathogen factors suggestive of ASB. Methods We conducted a 12-month prospective cohort study of adult inpatients with E. coli bacteriuria seen at a tertiary care hospital in St. Louis, Missouri, USA. Urine cultures were taken at the discretion of treating physicians. Bacterial isolates were tested for 14 putative virulence genes using high-throughput dot-blot hybridization. Results The median age of the 287 study patients was 65 (19–101) years; 78% were female. Seventy percent had community-acquired bacteriuria. One-hundred ten (38.3%) patients had ASB and 177 (61.7%) had symptomatic urinary tract infection (sUTI). Asymptomatic patients were more likely than symptomatic patients to have congestive heart failure (p = 0.03), a history of myocardial infarction (p = 0.01), chronic pulmonary disease (p = 0.045), peripheral vascular disease (p = 0.04), and dementia (p = 0.03). Patients with sUTI were more likely to be neutropenic at the time of bacteriuria (p = 0.046). Chronic pulmonary disease [OR 2.1 (95% CI 1.04, 4.1)] and dementia [OR 2.4 (95% CI 1.02, 5.8)] were independent predictors for asymptomatic bacteriuria. Absence of pyuria was not predictive of ASB. None of the individual virulence genes tested were associated with ASB nor was the total number of genes. Conclusions Asymptomatic E. coli bacteriuria in hospitalized patients was frequent and more common in patients with dementia and chronic pulmonary disease. Bacterial virulence factors could not discriminate symptomatic from asymptomatic bacteriurias. Asymptomatic E. coli bacteriuria cannot be predicted by virulence screening.

CD8+ T cells and NK cells from blister fluid of an EEM/SJS overlap highly express Fas ligand and Granulysin

INTRODUCTION Erythema exsudativum multiforme majus (EEMM) and Stevens-Johnson Syndrome (SJS) are severe cutaneous reaction patterns caused by infections or drug hypersensitivity. The mechanism by which widespread keratinocyte death is mediated by the immune system in EEMM/SJS are still to be elucidated. Here, we characterized the blister cells isolated from a patient with EEMM/SJS overlap and investigated its cause. METHODS Clinical classification of the cutaneous eruption was done according to the consensus definition of severe blistering skin reactions and histological analysis. Common infectious causes of EEMM were investigated using standard clinical techniques. T cell reactivity for potentially causative drugs was assessed by lymphocyte transformation tests (LTT). Lymphocytes isolated from blister fluid were analyzed for their expression of activation markers and cytotoxic molecules using flow cytometry. RESULTS The healthy 58 year-old woman suffered from mild respiratory tract infection and therefore started treatment with the secretolytic drug Ambroxol. One week later, she presented with large palmar and plantar blisters, painful mucosal erosions, and flat atypical target lesions and maculae on the trunc, thus showing the clinical picture of an EEMM/SJS overlap (Fig. 1). This diagnosis was supported by histology, where also eosinophils were found to infiltrate the upper dermis, thus pointing towards a cutaneous adverse drug reaction (cADR). Analysis of blister cells showed that they mainly consisted of CD8+ and CD4+ T cells and a smaller population of NK cells. Both the CD8+ T cells and the NK cells were highly activated and expressed Fas ligand and the cytotoxic molecule granulysin (Fig. 2). In addition, in comparison to NK cells from PBMC, NK cells in blister fluids strongly upregulated the expression of the skin-homing chemokine receptor CCR4 (Fig 4). Surprisingly, the LTT performed on PBMCs in the acute phase was positive for Ambroxol (SI=2.9) whereas a LTT from a healthy but exposed individual did not show unspecific proliferation. Laboratory tests for common infectious causes of EEMM were negative (HSV-1/-2, M. pneumoniae, Parvovirus B19). However, 6 weeks later, specific proliferation to Ambroxol could no longer be observed in the LTT (Fig 4.).

Bicarbonate enhances expression of the endocarditis and biofilm associated pilus locus, ebpR-ebpABC, in Enterococcus faecalis.

BACKGROUND: We previously identified ebpR, encoding a potential member of the AtxA/Mga transcriptional regulator family, and showed that it is important for transcriptional activation of the Enterococcus faecalis endocarditis and biofilm associated pilus operon, ebpABC. Although ebpR is not absolutely essential for ebpABC expression (100-fold reduction), its deletion led to phenotypes similar to those of an ebpABC mutant such as absence of pili at the cell surface and, consequently, reduced biofilm formation. A non-piliated ebpABC mutant has been shown to be attenuated in a rat model of endocarditis and in a murine urinary tract infection model, indicating an important participation of the ebpR-ebpABC locus in virulence. However, there is no report relating to the environmental conditions that affect expression of the ebpR-ebpABC locus. RESULTS: In this study, we examined the effect of CO2/HCO3(-), pH, and the Fsr system on the ebpR-ebpABC locus expression. The presence of 5% CO2/0.1 M HCO3(-) increased ebpR-ebpABC expression, while the Fsr system was confirmed to be a weak repressor of this locus. The mechanism by which the Fsr system repressed the ebpR-ebpABC locus expression appears independent of the effects of CO2(-) bicarbonate. Furthermore, by using an ebpA::lacZ fusion as a reporter, we showed that addition of 0.1 M sodium bicarbonate to TSBG (buffered at pH 7.5), but not the presence of 5% CO2, induced ebpA expression in TSBG broth. In addition, using microarray analysis, we found 73 genes affected by the presence of sodium bicarbonate (abs(fold) > 2, P < 0.05), the majority of which belong to the PTS system and ABC transporter families. Finally, pilus production correlated with ebpA mRNA levels under the conditions tested. CONCLUSIONS: This study reports that the ebp locus expression is enhanced by the presence of bicarbonate with a consequential increase in the number of cells producing pili. Although the molecular basis of the bicarbonate effect remains unclear, the pathway is independent of the Fsr system. In conclusion, E. faecalis joins the growing family of pathogens that regulates virulence gene expression in response to bicarbonate and/or CO2.

Retrospective study of indications for and outcome of perineal urethrostomy in cats

OBJECTIVES: To evaluate indications for and outcome of perineal urethrostomy in cats. METHODS: The medical records of 59 cats that had undergone perineal urethrostomy were evaluated. Short-term follow up information (for a period of four weeks following surgery) was available for all of the cats. Long-term follow up information (for a period of at least four months) was available for 39 cats. RESULTS: Early complications occurred in 25.4 per cent of cats and late complications were observed in 28.2 per cent of cats. The most frequent late complication was recurring bacterial urinary tract Infection. CLINICAL SIGNIFICANCE: Despite frequent complications and recurring signs of lower urinary tract disease, 32.2 per cent of the cats had a disease-free long-term outcome (mean four years, median 3.9 years), and 88.6 per cent of clients interviewed thought that their cats had a good quality of life after surgery.

Pressure Ulcer-Related Pelvic Osteomyelitis: A Neglected Disease?

Background. Decubitus ulcers can become complicated by pelvic osteomyelitis. Little is known about the epidemiology of pressure ulcer-related pelvic osteomyelitis. Methods. We performed a retrospective cohort study of adult patients with pressure ulcer and pelvic osteomyelitis admitted to an academic center from 2006 to 2011. Data on clinical presentation, diagnostic evaluation, and treatment during the index admission were collected. Outcome measures included length of hospital stay and number of readmissions in the subsequent year. Results. Two hundred twenty patients were included: 163 (74%) were para/quadriplegic and 148 (67%) were male (148; 67%). Mean age was 50 (±18) years. Pelvic osteomyelitis was the primary admission diagnosis for 117 (53%). Fifty-six (26%) patients had concurrent febrile urinary tract infection. Wound cultures collected for 113 patients (51%) were notable for methicillin-resistant Staphylococcus aureus (37; 33%), Streptococci (19; 17%), and Pseudomonas spp (20; 18%). Plain films were obtained in 89 (40%) patients, computed tomography scans were obtained for 81 (37%) patients, and magnetic resonance images were obtained for 40 (18%) patients. Most patients received osteomyelitis-directed antibiotics (153; 70%), 134 of 153 (88%) of which were scheduled to receive ≥6 weeks of treatment. Fifty-five (25%) patients underwent surgery during the index admission; 48 (22%) patients received a combined medical-surgical approach. One third of patients had ≥2 readmissions during the subsequent year. Patients treated with a combined approach were less likely to be readmitted than those who received antibiotics alone (0 [range, 0-4] vs 1 [0-7] readmissions; P = .04). Conclusions. This is one of the largest cohort studies of pressure ulcer-related pelvic osteomyelitis to date. Significant variations existed in diagnostic approach. Most patients received antibiotics; those treated with a combined medical-surgical approach had fewer hospital readmissions.

Renal function can be impaired in children with primary hyperoxaluria type 3

BACKGROUND Primary hyperoxaluria type 3 (PH3) is characterized by mutations in the 4-hydroxy-2-oxoglutarate aldolase (HOGA1) gene. PH3 patients are believed to present with a less severe phenotype than those with PH1 and PH2, but the clinical characteristics of PH3 patients have yet to be defined in sufficient detail. The aim of this study was to report our experience with PH3. METHODS Genetic analysis of HOGA1 was performed in patients with a high clinical suspicion of PH after the presence of mutations in the alanine-glyoxylate aminotransferase gene had been ruled out. Clinical, biochemical and genetic data of the seven patients identified with HOGA1 mutations were subsequently retrospectively reviewed. RESULTS Among the seven patients identified with HOGA1 mutations the median onset of clinical symptoms was 1.8 (range 0.4-9.8) years. Five patients initially presented with urolithiasis, and two other patients presented with urinary tract infection. All patients experienced persistent hyperoxaluria. Seven mutations were found in HOGA1, including two previously unreported ones, c.834 + 1G > T and c.3G > A. At last follow-up, two patients had impaired renal function based on estimated glomerular filtration rates (GFRs) of 77 and 83 mL/min per 1.73 m(2), respectively. CONCLUSIONS We found that the GFR was significantly impaired in two of our seven patients with PH3 diagnosed during childhood. This finding is in contrast to the early-impaired renal function in PH1 and PH2 and appears to refute to preliminary reassuring data on renal function in PH3.

Mycoplasma-induced minimally conscious state

Mycoplasma pneumoniae (M. pneumoniae) frequently causes community-acquired respiratory tract infection and often presents as atypical pneumonia. Following airborne infection and a long incubation period, affected patients mostly suffer from mild or even asymptomatic and self-limiting disease. In particular in school-aged children, M. pneumoniae is associated with a wide range of extrapulmonary manifestations including central nervous system (CNS) disease. In contrast to children, severe CNS manifestations are rarely observed in adults. We report a case of a 37 year-old previously healthy immunocompetent adult with fulminant M. pneumoniae-induced progressive encephalomyelitis who was initially able to walk to the emergency department. A few hours later, she required controlled mechanical ventilation for ascending transverse spinal cord syndrome, including complete lower extremity paraplegia. Severe M. pneumoniae-induced encephalomyelitis was postulated, and antimicrobial, anti-inflammatory and immunosuppressive therapy was applied on the intensive care unit. Despite early and targeted therapy using four different immunosuppressive strategies, clinical success was limited. In our patient, locked-in syndrome developed followed by persistent minimally conscious state. The neurological status was unchanged until day 230 of follow-up. Our case underlines that severe M. pneumoniae- related encephalomyelitis must not only be considered in children, but also in adults. Moreover, it can be fulminant and fatal in adults. Our case enhances the debate for an optimal antimicrobial agent with activity beyond the blood-brain barrier. Furthermore, it may underline the difficulty in clinical decision making regarding early antimicrobial treatment in M. pneumoniae disease, which is commonly self-limited.

The association between uterus shape and development of chronic conditions in a retrospective corhort of diethylstilbestrol-exposed women in Minnesota and Texas

Diethylstilbestrol (DES) exposed women are well known to be at increased risk of gynecologic cancers and infertility. Infertility may result from DES associated abnormalities in the shape of women's uteri, yet little research has addressed the effect of uterine abnormalities on risk of infertility and reproductive tract infection. Changes in uterine shape may also influence the risk of autoimmune disease and women's subsequent mental health. A sample of consenting women exposed in utero to hormone who were recruited into the DESAD project, underwent hysterosalpingogram (HSG) from 1978 to 1984. These women also completed a comprehensive health questionnaire in 1994 which included women's self-reports of chronic conditions. HSG data were used to categorize uterine shape abnormalities as arcuate shape, hypoplastic, wide lower segment, and constricted. Women were recruited from two of the four DESAD study sites in Houston (Baylor) and Minnesota (Mayo). All women were DES-exposed. Adjusted relative risk estimates were calculated comparing the range of abnormal uterine shaped to women with normal shaped uteri for each of the four outcomes: infertility, reproductive tract infection, autoimmune disease and depressive symptoms. Only the arcuate shape (n=80) was associated with a higher risk of infertility (relative risk [RR]= 1.53, 95% CI = 1.09, 2.15) as well as reproductive tract infection (RR= 1.74, 95% CI = 1.11, 2.73). In conclusion, DES-associated arcuate shaped uteri appeared to be associated with the higher risk of a reproductive tract infection and infertility while no other abnormal uterine shapes were associated with these two outcomes.^

Health status of Saudi women, the case of Yanbu al-Sinaiya

Detailed data on the health status of Saudi women are lacking. This cross sectional study attempts to provide a comprehensive description of the health status of Saudi females between the ages of 15-45 residing in Yanbu Al-Siniyah. The purpose is to assess women's needs for health services. The health status indicators are chronic tracer conditions, reported symptoms and multidimensional functioning levels. The generic functioning instrument of the Medical Outcome Study was used to estimate physical, social, and role functioning; degree of pain and health perceptions. The information was obtained by interviewing subjects and abstracting facts from their medical records. The results show functioning scores are in the "well health" range for physical, social, role and pain. Crowding and education have an equal or stronger effect of reducing functioning levels than the diagnosed tracer conditions. The highest prevalence conditions having a definite functional impact and diagnosed adequately in primary care are anemia, urinary tract infection, hemorrhoids, rheumatoid arthritis, caries and gingivitis. Reported symptoms strongly reducing function levels in this study are dyspnea, heart pain, incontinence, eye and skin problems, and joint ache. The impact of the reliability and validity of the measures used and other limitations of the results are discussed. Finally, some policy implications and suggestions for future study are presented. ^

Bacteremia and mortality within 30 days of catheter-associated bacteriuria

Background: The distinction between catheter-associated asymptomatic bacteriuria (CAABU) and catheter-associated urinary tract infection (CAUTI) has only recently been widely appreciated. Our aims were to describe the relationship between CAUTI/CAABU and subsequent bacteremia and to investigate whether CAUTI/CAABU and antimicrobial use was associated with either bacteremia or mortality within 30 days. ^ Methods: Our study design was retrospective cohort. Patients with a urinary catheter and a positive urine culture between October 2010 and June 2011 at a large tertiary care facility were included. A multivariable model for analysis was constructed which controlled for age, race, Charlson co-morbidity score, catheter type and duration, category of organism,antimicrobials and classification of the catheter-associated bacteriuria as CAUTI or CAABU. ^ Results: Data from 444 catheter associated urine culture episodes in 308 unique patients were included in the analysis. Overall mortality was 21.1% (61 of 308 patients) within 30 days. Among the 444 urine culture episodes, 402 (90.5%) of these episodes were associated with antibiotic use. 52 (11.7%) of episodes were associated with bacteremia, but only 3 episodes of bacteremia (0.7% of 444 CAB episodes) were caused by an organism from the urinary tract. One of these episodes was CAABU and the other 2 were CAUTI. Bacteremia within 30 days was associated with having CAUTI rather than CAABU and having an indwelling urinary catheter rather than a condom catheter. The variables which were found to be significant for mortality within 30 days were a higher Charlson co-morbidity score and the presence of Candida in the urine culture. Use of antimicrobial agents to treat the bacteriuria was not associated with an increase or decrease in either bacteremia or mortality. ^ Conclusions: Our findings call into question the practice of giving antimicrobial agents to treat bacteriuria in an inpatient population with nearly universal antimicrobial use. A better practice may be targeted treatment of bacteriuria in patients with risk factors predictive of bacteremia and mortality.^

Prescripción de medicamentos en las farmacias : una realidad preocupante

Se presume que la prescripción de medicamentos sin receta médica en las farmacias es una práctica frecuente. El objetivo fue conocer la conducta del personal de las farmacias ante una consulta realizada por estudiantes de medicina entrenados para actuar como pacientes simulados de las siguientes situaciones: 1: Infección respiratoria alta, 2: Diarrea aguda; 3: Disuria, 4: Ulcera genital, 5: Hipertensión arterial, 6: Cefalea aguda, 7: Artralgia de tobillo. Se efectuaron 100 entrevistas y cada una de las situaciones se realizó al menos 12 veces. En solo el 28% de los casos no se indicó tratamiento y las 72 prescripciones fueron realizadas por 38 farmacéuticos y 34 no profesionales. La medicación se consideró inadecuada en 58.3%, iatrogénica en 51.4% y la posología incorrecta en 50%. Los fármacos más indicados fueron antibióticos (23.6%), AINES (20.8%), antidiarreicos (11.8%) y antigripales (9.7%). Las situaciones 7 (100%), 1 (93.3%) y 2 (84.6%) tuvieron la mayor frecuencia de indicación de tratamiento y fue significativa la negativa a medicar en las situaciones 4 (OR, 0.16) y 5 (OR, 0.22) (p<0.05). La prescripción fue incorrecta en el 100% de las situaciones 2 y 4 y iatrogénica en el 100% de las situaciones 2, 4 y 5. En 48 casos se sugirió consulta médica y la situación 5 tuvo 4.27 veces más posibilidades de ser derivada (p= 0.01). Este estudio demuestra que en las farmacias del gran Mendoza es común la venta de medicamentos sin prescripción médica lo que compromete la seguridad y salud de las personas.

Mulheres motoristas de caminhão: realidades, estereótipos e desafios

Introdução A presença de mulheres no transporte rodoviário de cargas tem sido cada vez mais crescente e as repercussões do trabalho na vida das motoristas de caminhão ainda são desconhecidas pela comunidade científica. Objetivo - Caracterizar e analisar o trabalho de mulheres motoristas de caminhão e suas repercussões sobre sua saúde, a partir do relato de homens e mulheres motoristas de caminhão. Metodologia - O estudo com abordagem qualitativa utilizou a técnica do grupo focal, entrevistas individuais e observação não participante. Os grupos focais foram realizados em uma empresa transportadora localizada no estado de São Paulo e as entrevistas individuais em evento realizado na cidade de Itupeva/SP. Em oito encontros, grupos de motoristas de caminhão, discutiram a temática trabalho e saúde conduzida por meio de questões semiabertas. As mesmas questões foram utilizadas para as entrevistas individuais. Os relatos foram gravados, sendo o conteúdo das gravações transcrito e analisado por meio da metodologia Análise de Conteúdo de Bardin. A partir dos dados obtidos, construíram-se as seguintes categorias: A trajetória profissional de motoristas de caminhão; As mulheres no Transporte Rodoviário de Cargas; O trabalho; Um momento inesquecível na profissão e A saúde das mulheres motoristas na estrada. Resultados Tornar-se motorista de caminhão, para a maioria das mulheres, ocorreu por acaso, ou devido à uma necessidade financeira, ou a falta de perspectiva de emprego. Para as mulheres no Transporte Rodoviário de Cargas, o cotidiano de trabalho das profissionais está atravessado por aspectos como: a força física; dúvidas e preconceitos quanto à sua orientação sexual; o desafio em conciliar a vida dentro e fora do caminhão; conflitos na vida conjugal decorrentes da vida profissional; a discriminação sexual e a necessidade do reconhecimento no trabalho, bem como a falta de infraestrutura dedicada às trabalhadoras nas empresas e postos de parada nas rodovias brasileiras. O momento inesquecível nesta profissão, considerado por homens e mulheres, foi a primeira viagem. Os impactos do trabalho sobre a saúde das trabalhadoras recaíram sobre dores lombares e na coluna; problemas relacionados ao sono; necessidade de recorrer ao uso de drogas como anfetaminas e cocaína para manterem-se acordadas durante o trabalho; estresse; infecção urinária e uso ininterrupto de anticoncepcionais. Conclusões - A inserção das mulheres no transporte rodoviário de cargas desafia empresas e a infraestrutura existente nas rodovias do país a acompanharem as transformações sociais no mundo do trabalho, incluindo as demandas de um novo perfil de trabalhadoras. Descritores: trabalho, gênero, saúde, motoristas de caminhão.

Nutrição da gestante portadora de anemia falciforme, complicações maternas e resultados perinatais

O prognóstico da gestação é influenciado pelo estado nutricional materno. Sabe-se que, desde a infância, as pessoas portadoras da doença falciforme apresentam crescimento deficiente. Pouco se conhece sobre a evolução do estado nutricional materno na anemia falciforme. O objetivo foi analisar o estado nutricional de gestantes portadoras de anemia falciforme, avaliando o ganho de peso, o consumo dietético materno e os resultados adversos maternos e perinatais. Métodos: Foram avaliadas 26 gestantes portadoras de anemia falciforme SS e 23 SC, a partir do início do pré-natal especializado até o puerpério. Como grupo controle foram utilizadas 63 gestantes, sem comorbidades. O estado nutricional das gestantes foi avaliado de acordo com índice de massa corporal, pré-gestacional e ao final da gravidez, bem como analisado o ganho de peso materno. O consumo dietético foi analisado utilizando-se questionário de frequência alimentar, em cada trimestre, caracterizando-se o valor energético total e a ingestão de macronutrientes e micronutrientes. As complicações maternas e perinatais foram investigadas. O nível de significância foi 0,05 (alfa=5%). Resultados: O IMC pré-gestacional foi significativamente menor no grupo SS (mediana 20,3 kg/m2) quando comparado com os grupos SC (22,7 kg/m2, p < 0,05) e controle (23,2 kg/m2, p < 0,05). O baixo peso pré-gestacional (IMC < 18,5 kg/m2) foi significativamente mais frequente no grupo SS (15,4%) quando comparado aos grupos SC (4,4%) e controle (1,6%, p=0,009). Ao final da gestação, o grupo SS apresentou menor IMC (mediana 23,1 kg/m2) quando comparado com o grupo SC (26,1 kg/m2, p < 0,05) e controle (28,5 kg/m2, p < 0,05). O ganho ponderal na gestação foi menor no grupo SS (mediana 8,0 kg) quando comparado com o grupo SC (11,9 kg, p < 0,05) e Controle (13,7 kg, p < 0,05). Na análise do consumo dietético no 2º trimestre, constatou-se que os grupos SS e SC apresentaram menor consumo de proteínas (medianas, 73 g/d e 69 g/d) quando comparados aos controles (96 g/d, p < 0,05); e o consumo de cálcio foi menor no grupo SS comparado ao controle (mediana, 410 vs. 748 g/d, p<0,05). No 3º trimestre, houve menor consumo de proteínas pelo grupo SS quando comparado com os controles (mediana, 68 g/d vs. 93 g/d, p < 0,05); o consumo de vitamina A foi menor no grupo SS quando comparado aos controles (mediana, 447 vs. 940 mcg/d, p < 0,05); o consumo de vitamina E foi menor no grupo SS (mediana, 6 mg/d) quando comparado aos grupos SC (10 mg/d) e controle (7 mg/d, p < 0,05). As complicações maternas mais frequentes foram: crise álgica, 58% no grupo SS e 44% no SC (p=NS); infecção urinária, 31% no SS e 17% no SC (p=NS); e infecção pulmonar, 35% no SS e 9% no SC (p=NS). Houve diferença significativa no diagnóstico de sofrimento fetal: SS (36%), SC (14%) e controle (13%, p=0,032). Resultados perinatais adversos foram mais frequentes nos grupos SS e SC quando comparados aos controles. Conclusões: O estado nutricional das gestantes portadoras de doença falciforme SS caracterizou-se pela desnutrição materna, com baixo ganho ponderal na gestação. O consumo dietético de macronutrientes demonstrou ingestão inadequada de proteínas nos 2º e 3º trimestres. As complicações maternas e resultados perinatais adversos foram eventos frequentes nas gestantes portadoras de doença falciforme
