RESUMO

BACKGROUND: Children with repaired cleft lip and palate may present with middle ear effusion and disturbed speech due to velopharyngeal (VP) insufficiency. Furlow Z-palatoplasty with a buccinator myomucosal flap is one of the effective surgical techniques for primary cleft palate repair and lengthening of the palate. PURPOSE OF THE STUDY: This study aimed to evaluate the effect of Furlow Z-palatoplasty with buccal myomucosal flap as a primary cleft palate repair technique on the VP function during speech and the Eustachian tube function. MATERIALS AND METHODS: Forty patients with non-syndromic cleft lip and palate aged 3 to 7 years surgically repaired with Furlow palatoplasty with a buccinator myomucosal flap were assessed. Perceptual speech assessment, nasopharyngoscopic examination, otoscopic examination, and tympanometry were done for all patients to assess the speech and middle ear function. RESULTS: The percentage of mild hypernasality was significant in 22.5% of children with repaired cleft lip and palate, while 77.5% showed no hypernasality. Speech intelligibility was normal in 77.5% and mildly affected in 22.5% of children with repaired cleft palate. Compensatory misarticulations were recorded in 12.5% of children. Nasopharyngoscopic examination revealed adequate VP closure in 75% of children with repaired cleft palate. Twenty-five percent of children with repaired cleft lip and palate had middle ear effusion and required myringotomy with insertion of tympanostomy tubes. CONCLUSION: Primary cleft palate repair with Furlow Z-palatoplasty with buccal myomucosal flap had beneficial effects on speech outcomes. It was associated with a low prevalence of middle ear effusion, and a low number of tympanostomy tubes were needed.

RESUMO

BACKGROUND: Patients with HIV consult traditional healers (THs). These THs can both delay care for people living with HIV (PLHIV) and transmit HIV through poor infection control practices. The main objective of this study was to evaluate knowledge and practices of THs regarding HIV in Bukavu. METHODS: A cross-sectional study using quantitative approach was carried out among 71 THs in Bukavu City. The collected data included the following topics: personal and socio-demographic characteristics, HIV knowledge, and infection control practices. Descriptive statistics, independent-samples T-test or F-test, and multiple linear regression were used to analyze the data with a p-value < 0.05. RESULTS: The THs' mean age was 49.2 ± 11.2 years, and the majority were aged 40 to < 60 years. Males constituted 88.7% of THs with a male-to-female ratio of 7.9. In general, 47.9% of study participants had poor knowledge about HIV/AIDS infection, 45.1% of them had fair knowledge, and only 7.0% had good knowledge. Overall, 43.7% of THs had poor infection control practices, 52.1% of THs had fair practices, and only 4.2% of participants had good practices. Results of multiple linear regression analysis revealed that none of the personal and demographic variables studied were significant predictors of their knowledge about HIV/AIDS (p > 0.05). In terms of practices, two variables were significant predictors of infection control practices: living in Ibanda and receiving training in taking care of HIV/AIDS. CONCLUSION AND RECOMMENDATIONS: The study revealed that THs' knowledge about HIV infection was insufficient and that they had poor infection control practices. Formal standardized training on HIV infection should be organized for all THs so that they can always refer their patients to modern, reliable antiretroviral therapy (ART) clinics and reduce the risk of occupational exposure in their practices. Although PPE's assistance for THs is required in terms of protective measures, the province health authority must also oversee infection control procedures at THs' offices.

RESUMO

Introduction: The most widespread female malignancy is breast cancer (BC), considerable percentage of patients with triple-negative BC (TNBC) experience rapid progression, recurrence, and metastasis. BC has not historically been treated as an immunogenic cancer. Nonetheless, several researchers have started to concentrate on immunotherapy. Aim: The aim of the study is to investigate the immunohistochemical (IHC) expression of programmed death-ligand 1 (PD-L1) by stromal tumor-infiltrating lymphocytes (TILs) and tumor cells (TC) in female (TNBC) and to correlate with pathological features of such tumors, particularly those determine biologic behavior, such as the grade and stage the overall survival. Methodology: This is a retrospective study which includes 49 paraffin-embedded tumor tissue sections which were collected from breast surgery specimens either radical or conservative of female patients with TNBC. The samples were analyzed immunohistochemically for PD-L1 expression. Results: There were statistically significant relations among TC PD-L1 expression and TILs PD-L1 expression as well as relations among TILs PD-L1 expression with histologic grade, stromal TILs, and Ki-67 were statistically significant. Correlations between TC PD-L1 expression and N stage, histologic grade, and anatomic stage were statistically significant. Improved survival was detected within TILs PD-L1-positive cases; however, the correlation between the overall survival and PD-L1 expression in both TCs and stromal TIL was not statistically significant. Conclusion: PD-L1 expressed in tumors with poor prognostic features such as the high grade, advanced T stage, and high Ki-67 index, TILs PD-L1-positive cases experienced improved survival supporting its prognostic significance. However, the correlation with overall survival was not statistically significant.

RESUMO

OBJECTIVES: The main purpose of this study was evaluation of the effectiveness of secondary furlow palatoplasty with buccal myomucosal flap (FPBF) for the treatment of velopharyngeal insufficiency (VPI) in patients with a cleft palate who were treated with two flap palatoplasty (TFP) in their primary palate repair. MATERIAL AND METHODS: Twenty-three medically free children aged 4-8 years with non-syndromic and previously repaired cleft palate via TFP participated in the study. All patients received secondary surgery following the technique of FPBF. Preoperative speech evaluation was done before the secondary repair and 3 months after the surgery using a hypernasal speech scale, speech intelligibility scale, and nasopharyngoscopy. RESULTS: A statistically significant improvement was observed regarding the degree of hypernasality and speech intelligibility while comparing the preoperative scores after the primary surgery to the postoperative scores after the secondary surgery. In addition, a statistically significant improvement was found in the nasopharyngoscopic assessment. CONCLUSIONS: The incorporation of a buccal myomucosal flap with Furlow palatoplasty was successful in improving hypernasality, speech intelligibility, and nasopharyngoscopic scores in patients with cleft palate. TRIAL REGISTRATION: clinicaltrials.gov (NCT05626933). CLINICAL RELEVANCE: This technique might be the surgical technique of choice while treating patients who are suffering from VPI after cleft palate repair.

RESUMO

Given the high prevalence rate of suicidal ideation amongst medical students, medical lecturers and specialists as gatekeepers should be well-trained in suicide prevention. There is a need for validated measures to assess gatekeeper training gains for suicide prevention. The psychometric properties of the Advanced C.A.R.E. Suicide Prevention Gatekeeper Training Questionnaire (AdCARE-Q) were evaluated for a sample of medical lecturers and specialists in Malaysia. A total of 120 participants completed 24 items in the AdCARE-Q. Analysis of variance of perceived knowledge scores was performed. Exploratory factor analysis (EFA) was conducted. Reliability was calculated. The AdCARE-Q was reduced to 15 items that fit into two factors, "self-efficacy" and "declarative knowledge." Overall internal consistency was good with Cronbach's alpha = 0.84. The intraclass correlation coefficient between groups from the psychiatry department and non-psychiatry departments was good at 0.80. The oldest age group and participants from the Psychiatry department scored significantly higher than other groups in perceived knowledge of suicide prevention. This study found that the AdCARE-Q has adequate psychometric properties to assess suicide prevention gatekeeper training gains amongst medical lecturers and specialists. Confirmatory factor analysis is recommended for future studies.

RESUMO

The transcriptomic regulation induced by isotretinoin (13-cis retinoic acid) is still a matter of debate as short-term exposures of immortalized sebocytes with isotretinoin produced conflicting results. Based on translational evidence, it has been hypothesized that oral isotretinoin treatment upregulates the expression of the transcription factor p53. Twenty-five patients suffering from acne vulgaris were treated with isotretinoin (0.6 mg/kg body weight) for 6 weeks. Biopsies from back skin were taken before and after isotretinoin treatment for the determination of p53 expression by immunohistochemical staining, quantification of p53 protein concentration by enzyme-linked immunosorbent assay and TP53 gene expression by quantitative reverse transcription real time PCR. Fifteen socio-demographically cross-matched healthy volunteers served as controls. Isotretinoin treatment significantly increased the nuclear expression of p53 in sebaceous glands of treated patients compared to pre-treatment levels and p53 levels of untreated controls. Furthermore, the p53 protein and gene expression significantly increased in the skin after treatment. The magnitude of p53 expression showed an inverse correlation to acne severity score and body mass index. Under clinical conditions, isotretinoin induced the expression of p53, which controls multiple transcription factors involved in the pathogenesis of acne vulgaris including FoxO1, androgen receptor and critical genes involved in the induction of autophagy and apoptosis. Increased p53-FoxO1 signalling enhanced by systemic isotretinoin treatment explains the underlying transcriptomic changes causing sebum suppression but also the adverse effects associated with systemic isotretinoin therapy.

RESUMO

There is no consistently effective treatment for psoriatic nails. Topical and intralesional modalities have been recently investigated and showed promising efficacy and safety. To compare the efficacy and safety of intralesional injection of 5-fluorouracil (5-FU), methotrexate (MTX), triamcinolone acetonide (TA) versus topical calcipotriol plus urea 20% in the treatment of nail psoriasis. This study included 60 patients with nail psoriasis who were randomly assigned to 4 groups, each containing 15 patients. The first 3 groups received intralesional injection of 0.1 ml of 5-FU (group A), MTX (group B), and TA (group C) into the nail matrix and bed monthly for 3 months. Group D received a topical combination of calcipotriol/urea 20% twice daily for 3 months. Therapeutic response was assessed every month for 3 months using the target nail psoriasis severity index (NAPSI). The mean percentage of improvement was significantly higher in topical calcipotriol/urea combination (57.1 ± 26.4) than intralesional TA (44.2 ± 32.7), intralesional MTX (37.7 ± 14.2), and intralesional 5-FU (29.6 ± 14). Adverse effects were mild and insignificant in the studied groups. Topical calcipotriol/urea combination seems to be more effective and safe than intralesional injections of 5-FU, MTX, and TA.

RESUMO

Patients suffering from stroke may develop different complications including acute kidney injury (AKI). AKI affects mortality among the stroke patients. The association between stroke and AKI despite extensive research has been not completely understood. The study aimed to determine an AKI as an independent poor risk factor of cerebrovascular disease outcome among the stroke patients. Our objectives were to estimate AKI incidence among stroke patients at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, between 2013 and 2017 and assess the major risk factors related to AKI among stroke patients. The research population was sourced from the publicly available KAUH records from 2013 to 2017. The total number of stroke cases was 717 with a mean age of 63.94 ± 15.70 years. As many as 83.5% of cases had no AKI and 16.5% were suffered from AKI among total stroke patients studied. Furthermore, 74.1% of stroke patients were alive compared to 25.9% reported dead. The study concluded that AKI incidence is higher in stroke patients after admission immediately or during hospitalization. As such, the renal function file could be used as an early indicator upon stroke patients' admission to health-care facilities. Prevention and control of AKI seem to be very important among patients with stroke.

RESUMO

Chrysanthemum is one of the most consumed and most valuable cut flowers worldwide. In this study, the effectiveness of three concentrations of either thyme oil (300,400 and 500 mg/l) or clove oil (150,250 and 500 mg/l) as additives in holding the postharvest solutions of chrysanthemum ''Arctic Queen White'' cut flowers were investigated. The experiments were carried out as a completely randomized design in three replicates. Many postharvest characteristics have been evaluated, such as the vase life of cut flowers, diameters of head flowers and stem, dry matter of flowers, total vase water uptake, total loss of water, relative fresh weight. Additionally, the chlorophyll contents, total sugar, and bacterial counts were determined. The results showed that the longest vase life of cut chrysanthemum was 36.50, 33.40 days, and 35.88, 31.33 days by addition of either the thyme oil (500 mg/l) or clove oil (250 mg/l) in holding solution as compared with distilled water (18.09 and 17.22 days) in both seasons. The highest total vase water uptake and relative fresh weight were (225.00, 211.05 g/flower/day) and (79.89, 70.37 %) of cut chrysanthemum treated with 500 mg/l thyme oil in both seasons. Whereas the lowest total water loss in the two seasons was 155.11 and 156.60 g/flower/day was found with 400 mg/l thyme oil. The greatest chlorophyll a, b, carotenoids, and total sugar contents obtained from treated cut chrysanthemum with 500 mg/l thyme oil (6.89, 2.37, 5.99 mg/g, and 0.88 mg/gm D.W, respectively). Furthermore, the treatment of cut flowers with selected oils has significantly decreased the bacterial growth compared to the control. Whereas the minimum bacterial activities were <1 C.F.U/ml with cut chrysanthemum fortified with 500 mg/l thyme and clove oils. Moreover, the superlative treatments with thyme (500 mg/l) and clove (250 mg/l) showed a prime state of xylem vessels comparable with the control.thus, the usage (addition) of thyme and clove oils as a natural preservative in holding solutions instead of chemicals would be of great economic and environmental impact (Values).

RESUMO

OBJECTIVE: Apelin is a proinflammatory adipocyte-derived factor. The aim of this study was to evaluate the role and significance of serum apelin as a new sepsis marker in the identification of full-term and preterm new-born infants with early-onset sepsis. MATERIAL AND METHODS: This was a case-control study. We included 80 neonates. The cases were divided into 2 groups; neonates with early-onset sepsis and control group with neonates non-sepsis. Apelin was quantified by enzyme-linked immunosorbent assay. RESULTS: There was a significant elevation in the mean values of serum apelin in the early-onset sepsis group (1214.7 ± 273.06 pg/mmol) than in the non-septic neonates 116.27 ± 21.96 pg/mmol (P < .0001). Apelin values were correlated to clinical sepsis and hematological scores as well as C-reactive protein. Serum apelin concentration was significantly higher among culturepositive cases than the culture-negative cases (mean ± SD was 1239.52 ± 268.47 and 929.42 ± 136.97 pg/mmol, respectively, P < .0001). Moreover, the apelin level was higher in non-survivor neonates than in the survivors in the early-onset sepsis group. No significant difference was found between preterm and full-term new-born infants with regard to the apelin values. The best cut-off estimate of apelin to diagnose early sepsis was >178.33 pg/mmol. CONCLUSION: Apelin may be useful in the diagnosis and prognostic prediction of neonates with early-onset sepsis.

RESUMO

Direct-acting antivirals (DAAs) are associated with remarkable efficiency and safety profiles; however, their effect on erectile function remains insufficiently studied. This study included 200 male patients with chronic hepatitis C virus (HCV) infection divided into groups A and B and 100 healthy controls. Group A received sofosbuvir (SOF) 400 mg/ledipasvir 90 mg (Harvoni), whereas group B received SOF 400 mg/ daclatasvir 60 mg for 3 months. The Arabic version of the five-item International Index of Erectile Function-5 (IIEF-5) questionnaire was used to assess erectile function before and after completion of therapy and 3 months after. Erectile dysfunction (ED) was present in 74.5% of the patients and 14% of the controls. Immediately after treatment, group B (22.5±2.6) had a significantly higher mean IIEF-5 score than did group A (17.3±3.3) (p<0.001). Three months after treatment, all groups had no significant differences in mean IIEF-5 scores (group A: 23.1±1.9, group B: 23.3±1.9, controls: 23.7±2.3); however, free testosterone (FT) levels were significantly higher compared with pre-treatment. Both treatment regimens were associated with the improvement of erectile function and sex hormonal milieu. SOF/daclatasvir was associated with earlier improvement of erectile function compared with SOF/ledipasvir.

RESUMO

BACKGROUND: Violence against women (VAW) is a major global public health problem with serious consequences. We aimed to estimate the prevalence of VAW aged 18-45 yr in a slum area in Helwan, Cairo, to assess their knowledge and perspective regarding VAW, and to assess their help-seeking practice in response to violence. STUDY DESIGN: Cross-sectional design. METHODS: This community based survey was carried out among 657 women in a slum area in Helwan, Cairo, Egypt in 2018. Data about the women's knowledge about VAW, exposure to different forms of violence and their frequency, women's perspective towards violence, and their healthcare-seeking behavior on exposure to violence were collected using an interviewing questionnaire. RESULTS: The prevalence of exposure to at least one type of intimate partner violence (IPV) was 59.1% with psychological violence ranking 1st followed by physical violence. Most women exposed to IPV reported that they have never asked for healthcare upon exposure to violence. One third had good knowledge. Most had favorable perspective against VAW. CONCLUSION: Most women suffered some kind of violence. They, however, did not seek help most of the time.

RESUMO

Several theories were proposed to explain the pathophysiology of varicocele-related infertility seen in some patients. Our aim was to study the levels of angiotensin II in semen and angiotensin II type 2 receptor expression on spermatozoa in varicocele patients in relation to their fertility status and to evaluate the influence of varicocelectomy on their levels in infertile varicocele patients. Thirty fertile and 30 infertile varicocele patients and 30 healthy controls were subjected to measurement of reproductive hormones, semen analysis, measurement of seminal angiotensin II and evaluation of angiotensin II type 2 receptor expression on spermatozoa. Infertile varicocele patients underwent varicocelectomy and were re-evaluated for the same parameters after the operation. Sperm concentration, morphology, progressive motility, seminal angiotensin II and angiotensin II type 2 receptor expression were significantly lower in infertile varicocele patients compared with the other groups. Post-operative values showed significant increase in the studied parameters compared with the pre-operative values but not to other two groups. A significant positive correlation between angiotensin II type 2 receptor expression and progressive motility was detected in all studied groups. In conclusion, dysregulation of angiotensin II and angiotensin II type 2 receptor in varicocele patients may be involved in varicocele-related infertility.

RESUMO

BACKGROUND: Congenital anomalies (CAs) are structural, functional, or metabolic anomalies that originate during intrauterine life and can interfere with the body functions. In Egypt, the prevalence of CAs is increasing. The study aimed to estimate the frequency, describe the types, and identify the possible risk factors of CAs among infants attending the Pediatric University Hospital, Alexandria, Egypt. METHODS: A retrospective case series and a case-control study were conducted. Patients' records for the years 2010-2015 were reviewed, and a sample of 200 infants (100 cases and 100 controls) was taken from infants presented to Pediatrics, Pediatric Surgery, and Genetics Clinics of the hospital. Data were collected using a record review checklist and a predesigned interviewing questionnaire. RESULTS: The study revealed that congenital anomalies of the digestive system (38.0%), musculoskeletal system (32.9%), and circulatory system (11.0%) were the most common types of CAs. Males were more affected with CAs than females (63% versus 37%). The major risk factors for CAs were old-aged parents, complications during pregnancy, unprescribed medications and excessive vitamin A intake during pregnancy, exposure to chemicals and pesticides during pregnancy, and living near mobile strengthening stations. CONCLUSION: Congenital malformations of the digestive, musculoskeletal, and circulatory systems were the most common types of CAs in the Pediatric Hospital. To prevent CAs, there is a need to restrict the prescription of medications that may have a teratogenic effect.

RESUMO

OBJECTIVE: To investigate the effect of chronic daily administration of different doses of tadalafil on the structure of the seminiferous tubules and on spermatogenesis. MATERIALS AND METHODS: Sixty adult male Wistar rats were included; they were divided into four groups: a control group (group I) and groups II, III, and IV that received daily tadalfil in doses of 0.45, 0.9, and 1.8 mg/kg for 12 weeks (equivalent to human doses of 5, 10, and 20 mg daily), respectively. The epididymis was processed for evaluation of sperm parameters, serum testosterone was measured, Johnsen score for rats was calculated, and testicular histopathological and ultrastructural examinations were performed. RESULTS: Serum testosterone was significantly lower in group IV than in groups I and II. Moreover, posttreatment values in group IV were significantly lower than pretreatment values. A significant decline in sperm motility and morphology was detected in groups III and IV compared to groups I and II. Sperm count was significantly lower in group IV compared to the other groups. Johnsen score was significantly lower in groups III and IV compared to groups I and II and in group IV compared to group III. In addition, histopathological and ultrastructural degenerative changes in rat testes were detected; these changes were dose dependent and increased with increasing the dose of tadalafil. CONCLUSION: Chronic daily oral administration of tadalafil to male albino rats demonstrates a dose-dependent alteration to testicular histology and semen parameters. The influence of these changes on the actual fertility of these animals remains to be determined.

RESUMO

The distribution and monthly abundance of mosquito larvae in released water, drainage canals and sewage water tanks in Ismailia governorate were investigated. The results obtained indicated the presence of five culicine (Culex. pipiens, Cx. pusillus, Cx. perexiguus, Cx. theleri and Ochlerotatus. caspius) and two anopheline (Anopheles. multicolor and An. pharoensis) mosquito species. Significantly higher larval density was recorded in sewage water (n= 5534; 46.08%) as compared with released water (n = 2903; 24.17%) and drainage water (n= 3573; 29.75%). Culex pipiens was the most dominant mosquito species in the three habitats. The effects of environmental parameters including pH, biological and chemical oxygen demands, day time water temperature, plant growth, salinity, total organic matter and concentrations of heavy metals on larval population density were investigated. The positive correlations observed between heavy metals concentrations in the three habitats suggested relative uniformity of the sources of metal pollutants. Culex pipiens larvae demonstrated high tolerance to elevated levels of heavy metals in sewage water and compensatory effects of high nutrient levels generally associated with sewage or domestic waste. High densities of culicine larvae were accompanied by low density of anopheline larvae. This was attributed to water chemistry & competitive interactions.

RESUMO

BACKGROUND: Systemic sclerosis (SSc) is a connective tissue disorder characterized by tissue hypoxia and excessive fibrosis of skin and internal organs. OBJECTIVE: To evaluate the possible role of angiogenesis imbalance in the pathogenesis of SSc. SUBJECTS AND METHODS: Twenty-five SSc patients and 20 age- and sex-matched healthy controls were included. Assay of serum vascular endothelial growth factor (VEGF) and endostatin was done for all patients and controls using enzyme-linked immunosorbent assay. Patients were subjected to modified Rodnan skin score (mRss), pulmonary function tests (PFTS) and skin biopsies for histopathological skin thickness score assessment. RESULTS: There was significant increase in the mean levels of serum VEGF and endostatin in SSc patients compared to controls (t = 4.07, P < 0.001). Mean values of serum endostatin was significantly increased in late compared to early stages of disease (t = 6.65, P < 0.01). A significant positive correlation was found between serum levels of endostatin, mRss and histopathological skin thickness score (r = 0.99, 0.94, respectively, P < 0.01). SSc patients with ischemic manifestations had significantly higher levels of serum endostatin compared to those without ischemic manifestations (t = 6.27, P < 0.001). SSc patients with restricted PFTS had significantly higher levels of serum endostatin compared to those without pulmonary manifestations (t = 4.3, P < 0.001). CONCLUSION: Angiogenic inhibitor (endostatin) is induced and outweighs angiogenic inducer (VEGF) in late stages of SSc. Increased serum endostatin is associated with skin sclerosis severity and pulmonary fibrosis and favors SSc disease progression.

RESUMO

BACKGROUND: Unsafe injection practices are a major public health problem and can lead to the transmission of bloodborne pathogens, including hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). METHODS: The present study was conducted to determine the nature and magnitude of unsafe injection practices in healthcare facilities in Hodeidah governorate, Yemen. The study was conducted in two hospitals and a representative sample of the governorate's health centers. A total of 1600 injections were observed in these facilities. RESULTS: This study revealed several unsafe practices, particularly the recapping of needles after use, which occurred in 61.1% and 36.8% of the observations in the hospitals and the health centers, respectively. CONCLUSION: This study showed that most healthcare workers (HCWs) followed the proper injection protocols but performed some procedures that exposed themselves and the community to the risk of needlestick injuries (NSIs) and bloodborne infections.

RESUMO

Systemic lupus erythematosus (SLE) patients have an increased risk of atherosclerosis. Identification of at-risk patients and the pathogenesis of atherosclerosis in SLE remain elusive. Paraoxonase 1 (PON1) and anti-apolipoprotein A-I antibody (anti-Apo A-I) appear to have a potential role in premature atherosclerosis in SLE. The aim of this work was to study PON1 activity and anti-Apo A-I antibody in SLE female patients and to demonstrate their relations to disease activity as well as disease related damage. Forty SLE female patients and 40 apparently healthy volunteers were included. Anti-Apo A-I antibodies levels and PON1 activity levels were assessed. Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and systemic Lupus International Collaboration Clinics (SLICC)/American College of Rheumatology (ACR) damage index were preformed in all patients. Compared with controls, SLE patients showed significantly lower PON1 activity and significantly higher titers of anti-Apo A-I. Anti-Apo A-I antibody titers correlated inversely with PON1 activity. Elevated titers of anti-Apo A-I antibody and reduced PON activity were related to increased SLEDAI and (SLICC/ACR) damage index scores. We concluded that there is decreased PON1 activity and formation of anti-Apo A-I antibodies in female patients with SLE. SLE-disease activity assessed by SLEDAI and SLE disease related organ damage assessed by SLICC/ACR damage index are negatively correlated with PON1 activity and positively correlated with anti-Apo A-I antibodies. PON1 activity and anti-Apo A-I antibodies might be involved in the pathogenesis of atherosclerosis in SLE patients.

RESUMO

OBJECTIVE: To identify the relation between serum levels of N-terminal pro-brain natriuretic peptide (NT-pro BNP) and severity of systemic sclerosis (SSc). SUBJECT AND METHODS: 25 SSc patients and 25 age- and sex-matched healthy controls were included. Assay of serum NT-pro BNP was done for all patients and controls. Patients were subjected to modified Rodnan skin score (mRss), echocardiography, pulmonary function tests and skin biopsies for histopathological skin thickness score assessment. There was a significant increase in the mean values of serum levels of NT- pro BNP in SSc patients compared to controls (t=11, p<0.001). RESULTS: There was a significant positive correlation between serum levels of NT-pro BNP in SSc patients and mRss, systolic pulmonary artery pressure (sPAP) and histopathological skin thickness score (r=0.93, r=0.92, r=0.92, p<0.001 respectively). There was a significant increase in the mean value of serum levels of NT-pro BNP and sPAP in SSc patients with restrictive pulmonary affection compared to those with normal respiratory function tests (p<0.001). CONCLUSION: NT-pro BNP may be a useful biological marker for assessing the severity of SSc as it has a role in detecting the extent of skin fibrosis, the severity of PAH and the degree of restricted pulmonary involvement in SSc patients.
