Investigating the Role of FABP4 in Diabetes and Obesity and the Influence of Age and Ethnicity: A Comprehensive Analysis of a Cohort from the KEDP-Study.

Adipocyte P2 (aP2), also known as FABP4, is an adipokine that adipose tissue produces and expresses in macrophages. Its primary role is to facilitate the transportation of fatty acids across cell membranes. Numerous studies have reported associations between FABP4 and the development of metabolic disorders. However, there is limited knowledge regarding FABP4 expression in diabetes and obesity, especially about different age groups, genders, and ethnicities. This study aims to investigate the association between FABP4 levels, diabetes mellitus, and obesity within various ethnic groups. We measured plasma FABP4 concentrations in a cohort of 2083 patients from the KDEP study and gathered anthropometric data. Additionally, we collected and analyzed clinical, biochemical, and glycemic markers using multivariate regression analysis. The average FABP4 concentration was significantly higher in female participants than in males (18.8 ng/mL vs. 14.4 ng/mL, p < 0.001, respectively), and in those over 50 years old compared to those under 50 years of age (19.3 ng/mL vs. 16.2 ng/mL, p < 0.001, respectively). In this study, significant positive associations were found between the plasma level of FABP4 and obesity markers: BMI (r = 0.496, p < 0.001), hip circumference (r = 0.463, p < 0.001), and waist circumference (WC) (r = 0.436, p < 0.001). Similar observations were also seen with glycemic markers, which included HbA1c (r = 0.126, p < 0.001), fasting blood glucose (FBG) (r = 0.184, p < 0.001), fasting insulin (r = 0.326, p < 0.001), and HOMA-IR (r = 0.333, p < 0.001). Importantly, these associations remained significant even after adjusting for age, gender, and ethnicity. Furthermore, FABP4 levels were negatively associated with male gender (ß: -3.85, 95% CI: -4.92, -2.77, p < 0.001), and positively associated with age (ß: 0.14, 95% CI: 0.096, 0.183, p < 0.001), BMI (ß: 0.74, 95% CI: 0.644, 0.836, p < 0.001), and fasting insulin (ß: 0.115, 95% CI: 0.091, 0.138, p < 0.001). In this study, plasma FABP4 levels were significantly higher in diabetic and obese participants, and they were strongly influenced by age, gender, and ethnicity. These findings suggest that FABP4 may serve as a valuable prognostic and diagnostic marker for obesity and diabetes, particularly among female patients, individuals over 50 years old, and specific ethnic groups.

Impact of pharmacological interventions on anthropometric indices in women with polycystic ovary syndrome: A systematic review and meta-analysis of randomized controlled trials.

CONTEXT: Polycystic ovary syndrome (PCOS) is a heterogeneous condition affecting women of reproductive age and is associated with increased body weight. OBJECTIVE: To review the literature on the effect of different pharmacological interventions on the anthropometric indices in women with PCOS. DATA SOURCES: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane library, and the Web of Science in April 2020 with an update in PubMed in March 2021. STUDY SELECTION: The study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA)2020. DATA EXTRACTION: Reviewers extracted data and assessed the risk of bias using the Cochrane risk of bias tool. RESULTS: 80 RCTs were included in the meta-analysis. Metformin vs placebo showed significant reduction in the mean body weight (MD: -3.13 kg; 95% confidence interval [CI]: -5.33 to -0.93, I² = 5%) and the mean body mass index (BMI) (MD: -0.75 kg/m2 ; 95% CI: -1.15 to -0.36, I² = 0%). There was a significant reduction in the mean BMI with orlistat versus placebo (MD: -1.33 kg/m²; 95% CI: -2.16 to -0.66, I² = 0.0%), acarbose versus metformin (MD: -1.26 kg/m²; 95% CI: -2.13 to -0.38, I² = 0%), and metformin versus pioglitazone (MD: -0.91 kg/m²; 95% CI: -1.62 to -0.19, I² = 0%). A significant increase in the mean BMI was also observed in pioglitazone versus placebo (MD: + 2.59 kg/m²; 95% CI: 1.78-3.38, I² = 0%) and in rosiglitazone versus metformin (MD: + 0.80 kg/m²; 95% CI: 0.32-1.27, I² = 3%). There was a significant reduction in the mean waist circumference (WC) with metformin versus placebo (MD: -1.21 cm; 95% CI: -3.71 to 1.29, I² = 0%) while a significant increase in the mean WC with pioglitazone versus placebo (MD: + 5.45 cm; 95% CI: 2.18-8.71, I² = 0%). CONCLUSION: Pharmacological interventions including metformin, sitagliptin, pioglitazone, rosiglitazone orlistat, and acarbose have significant effects on the anthropometric indices in women with PCOS.

Effect of pharmacological interventions on lipid profiles and C-reactive protein in polycystic ovary syndrome: A systematic review and meta-analysis.

CONTEXT: Polycystic ovary syndrome (PCOS) is a heterogeneous condition affecting women of reproductive age. It is associated with dyslipidaemia and elevated plasma C-reactive protein (CRP), which increase the risks of cardiovascular disease (CVD). OBJECTIVE: To review the existing evidence on the effects of different pharmacological interventions on lipid profiles and CRP of women with PCOS. DATA SOURCES: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane Library, and Web of Science in April 2020 and updated the results in March 2021. STUDY SELECTION: The study included randomized controlled trials (RCTs) and follows the 2020 Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). DATA EXTRACTION: Two independent researchers extracted data and assessed for risk of bias using the Cochrane risk of bias tool. Covidence systematic review software were used for blinded screening and study selection. DATA SYNTHESIS: In 29 RCTs, there were significant reductions in triglycerides with atorvastatin versus placebo [mean difference (MD): -0.21 mmol/L; 95% confidence interval (CI): -0.39, -0.03, I2 = 0%, moderate grade evidence]. Significant reductions were seen for low-density lipoprotein cholesterol (LDL-C) with metformin versus placebo [standardized mean difference (SMD): -0.41; 95% CI: -0.85, 0.02, I2 = 59%, low grade evidence]. Significant reductions were also seen for total cholesterol with saxagliptin versus metformin (MD: -0.15 mmol/L; 95% CI: -0.23, -0.08, I2 = 0%, very low grade evidence). Significant reductions in C-reactive protein (CRP) were seen for atorvastatin versus placebo (MD: -1.51 mmol/L; 95% CI: -3.26 to 0.24, I2 = 75%, very low-grade evidence). CONCLUSION: There were significant reductions in the lipid parameters when metformin, atorvastatin, saxagliptin, rosiglitazone and pioglitazone were compared with placebo or other agents. There was also a significant reduction of CRP with atorvastatin.

Impact of pharmacological interventions on insulin resistance in women with polycystic ovary syndrome: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex endocrine condition affecting women of reproductive age. It is characterized by insulin resistance and is a major risk factor for type 2 diabetes mellitus (T2DM). The objective was to review the literature on the effect of different pharmacological interventions on insulin resistance in women with PCOS. DESIGN: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane library and the Web of Science in April 2020 and updated in March 2021. The study follows the 2020 Preferred Reporting Items for Systematic reviews and Meta-ana. Reviwers extracted data and assessed the risk of bias using the Cochrane risk of bias tool. RESULTS: In 58 randomized controlled trials there were significant reductions in the fasting blood glucose (FBG) with metformin versus placebo (standardized mean difference [SMD]: -0.23; 95% confidence interval [CI]: -0.40, -0.06; I² = 0%, low-grade evidence), and acarbose versus metformin (mean difference [MD]: -10.50 mg/dl; 95% CI: -15.76, -5.24; I² = 0%, low-grade evidence). Significant reductions in fasting insulin (FI) with pioglitazone versus placebo (SMD: -0.55; 95% CI: -1.03, -0.07; I² = 37%; p = .02, very-low-grade evidence). A significant reduction in homoeostatic model assessment of insulin resistance (HOMA-IR) was seen with exenatide versus metformin (MD: -0.34; 95% CI: -0.65, -0.03; I² = 0%, low-grade evidence). No effect on homoeostatic model assessment of beta cells (HOMA-B) was observed. CONCLUSIONS: Pharmacological interventions, including metformin, acarbose, pioglitazone and exenatide have significant effects on FBG, FI, HOMA-IR but not on HOMA-B.

The Effect of Thiazolidinediones in Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a complex endocrine condition affecting women of reproductive age. It is characterised by insulin resistance and is a risk for type 2 diabetes mellitus (T2DM). The aim of this study was to review the literature on the effect of pioglitazone and rosiglitazone in women with PCOS. METHODS: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane Library and the Web of Science in April 2020 and updated in March 2023. Studies were deemed eligible if they were randomised controlled trials (RCTs) reporting the effect of pioglitazone and rosiglitazone in PCOS. The study follows the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two reviewers independently extracted data and assessed the risk of bias using the Cochrane risk of bias tool. RESULTS: Out of 814 initially retrieved citations, 24 randomised clinical trials (RCTs) involving 976 participants were deemed eligible. Among women with PCOS, treatment with rosiglitazone compared to metformin resulted in a significant increase in the mean body weight (mean difference (MD) 1.95 kg; 95% CI 0.03-3.87, p = 0.05). Metformin treatment was associated with a reduction in mean body mass index (BMI) compared to pioglitazone (MD 0.85 kg/m2; 95% CI 0.13-1.57, p = 0.02). Both pioglitazone compared to placebo (MD 2.56 kg/m2; 95% CI 1.77-3.34, p < 0.00001) and rosiglitazone compared to metformin (MD 0.74 kg/m2; 95% CI 0.07-1.41, p = 0.03) were associated with a significant increase in BMI. Treatment with pioglitazone compared to placebo showed a significant reduction in triglycerides (MD - 0.20 mmol/L; 95% CI - 0.38 to - 0.03, p = 0.02) and fasting insulin levels (MD - 11.47 mmol/L; 95% CI - 20.20, - 2.27, p = 0.01). Rosiglitazone compared to metformin was marginally significantly associated with a reduction in the luteinising hormone (LH) (MD - 0.62; 95% CI - 1.25-0.00, p = 0.05). CONCLUSION: Both pioglitazone and rosiglitazone were associated with significant increases in body weight and BMI when compared with metformin or placebo. Pioglitazone significantly reduced triglycerides and fasting insulin when compared with placebo while rosiglitazone showed a modest reduction of LH when compared with metformin.

Epidemiological, Clinical, and Histopathological Features of Salivary Gland Tumors among 150 Sudanese Patients: 10 Years' Experience.

Background and Objectives: Salivary gland tumors (SGTs) are serious challenges to pathologists. Herein, we aimed to assess epidemiological and histopathological characteristics of SGTs among Sudanese patients. Materials and Methods: This retrospective descriptive study was undertaken at The pathology department in Khartoum State between 2008 and 2018. Patient records, histopathological reports, and slides were retrieved; and re-examined by two histopathologists. Diagnoses were reclassified according to the 2017 WHO classification of SGTs. Results: Overall, 150 cases of Sudanese patients with SGT were included (90 [60%] males and 60 [40%] females). Among these, 105 were benign (70%) and 45 were malignant (30%). The parotid glands were the most common site for both benign and malignant tumors (77/150; 51%: 59 benign (76.6%) and 18 malignant [23.4%]). The next common site was the submandibular gland (54 [36%]: 38 benign [70.3%] and 16 malignant [29.7%]), followed by minor salivary glands (19 [12.7%]: 8 benign and 11 malignant [57.9%]). Benign gland entities included pleomorphic adenoma (88/105; 83.7%), oncocytoma (5/105; 4.8%), myoepithelioma (4/105; 3.8%), Whartin tumors (3/105; 2.9%), basal cell adenoma (3/105; 2.9%), and sialolipoma (2/105; 1.9%). Malignant gland entities included adenoid cystic carcinoma (12; 26.7%), mucoepidermoid carcinoma (10; 22,2%), acinic cell carcinoma (6; 13.3%), poorly differentiated carcinoma (4; 8.9%), adenocarcinoma NOS (not otherwise specified) (4; 8.9%), basal cell adenocarcinoma (3; 6.7%), carcinoma ex pleomorphic adenoma (3; 6.7%), polymorphous adenocarcinoma (2; 4.4%), salivary duct carcinoma (1; 2.2%), and epithelial-myoepithelial carcinoma (2.2%). Conclusions: SGTs shared several epidemiological and histopathological features, exhibiting high incidence in the parotid and submandibular glands, lower prevalence in minor glands, and greater male predominance.

Vesical ectopic pregnancy due to vesicouterine fistula: A case report with literature review.

This case report describes the presentation, diagnosis, and surgical management of a rare vesical ectopic pregnancy in a 36-year-old woman with a history of multiple cesarean sections. The patient presented with symptoms of suprapubic pain, fever, and amenorrhea. An initial ultrasound indicated retained products of conception, leading to a preliminary diagnosis of septic miscarriage. However, subsequent rescanning revealed an empty uterus and a non-viable fetus within the bladder, connected to the uterine cavity. Cystoscopy confirmed the presence of fetal parts inside the bladder. Finally, a laparotomy was performed and the fetus was removed from the bladder with repair of the underlying uterovesical fistula. An uneventful postoperative period ensued. The literature review revealed only four previously reported cases with similar overall presentations. This case highlights the importance of considering vesical ectopic pregnancies in patients with a history of cesarean sections and unusual symptoms, as prompt surgical intervention is crucial for ensuring successful management of the condition.

Drug-Eluting Stents: Their Preventative/Prophylactic Role Against Gemcitabine Induced Acute Coronary Syndrome.

Acute coronary syndrome (ACS), a subdivision of ischemic cardiac disease, is the sudden occlusion of coronary vessels that results in decreased blood supply to heart muscles and possible infarction. Though some of the etiologies are hypertension, hyperlipidemia, diabetes mellitus, and tobacco; certain types of chemotherapies play a major role. Percutaneous coronary intervention (PCI) has shown lifesaving results via drug-eluting stent (DES) deployment into occluded vessels. In this study, DES utilization among patients receiving chemotherapy will be assessed to observe if it provides any prevention against ACS. Articles were systematically screened in three databases such as PubMed, PubMed Central (PMC), and Medical Literature Analysis and Retrieval System Online (MEDLINE) using keywords and Medical Subject Heading (MeSH) terms for applicable articles. Additionally, a few relevant articles from the Cochrane Library, Molecular Diversity Preservation International (MDPI), and The New England Journal of Medicine were also used. Inclusion/exclusion criteria were applied post article screening via title and abstracts. Quality appraisal check was done using the Scale for the Assessment of Narrative Review Articles (SANRA) checklist, A Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist, Cochrane bias assessment tool, and Joanna Briggs Institute (JBI) checklist. Ten related studies were strictly reviewed. DES did not appear to play a preventable role against ACS during chemotherapy as no study was found assessing DES prophylactically and its efficacy in cancer patients. Future clinical trials on DES prophylactic use might be beneficial to evaluate if ACS adversities of chemotherapy can be prevented. This review is of significant benefit as cardiovascular adversities would not impede chemotherapy efficacy as cardiac adversities would not be part of the equation.

The Relationship Between Caffeine and Caffeinated Drinks in Causing Intracranial Hemorrhage in the Elderly Aspirin-Taking Population: A Systematic Review.

Caffeinated drinks are the most widely consumed beverages globally and their intake has increased in the elderly. Caffeine exhibits dose-dependent adverse effects. Low to moderate doses cause anxiety, restlessness, irritability, and nausea. High doses of 3-5g can affect different physiological systems and lead to detrimental effects like palpitations, hypertension, agitation, seizures, and coma. Low-dose aspirin is the most used anticoagulant in preventing ischemic vascular events. An increased risk of intracranial hemorrhage is associated with low-dose aspirin with an intensified intracerebral hemorrhage risk. The aim of this research is to explore the association between caffeine and aspirin in causing lethal intracranial hemorrhage in the older population. Because of the devastating nature of intracranial hemorrhages and the inconsistent published data on the risk of intracranial hemorrhage in individuals taking both aspirin and caffeine, we conducted a systematic review considering the elderly population. We conducted the study following the reporting guidelines for systematic review and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. Inclusion and exclusion criteria were determined. Data was collected from PubMed, PubMed Central® (PMC), National Library of Medicine (MEDLINE), Google Scholar, Multidisciplinary Digital Publishing Institute (MDPI), and Web of Science by applying keywords and Medical Subject Headings (MeSH) terms individually. Our initial search yielded 155,270 articles, which were scrutinized, and duplicates were removed for accuracy. Of these, a total of 13 research papers were finally extracted using the PRISMA recommendations and applying other inclusion and exclusion criteria. With the help of our systematic review, we could determine that both aspirin and caffeine portrayed a role in causing intracranial hemorrhage independently, but further studies are recommended to evaluate if both could lead to similar adverse effects when taken collectively.

The Effectiveness of Statins as Potential Therapy for Multiple Sclerosis: A Systematic Review of Randomized Controlled trials.

Evidence of the effectiveness of statins, the lipid-lowering agents in retarding the progression of Multiple Sclerosis (MS), a disabling neurological disease with autoimmune etiology, have been highlighted in animal studies and observational studies. The proposed immune-modulatory actions and neuroprotective effects of statins make them a promising treatment option for MS that needs to be explored further. In this systematic review, we aim to investigate the role of different statins as monotherapy or in combination with the established MS medications in improving the clinical and radiological course of MS variants, including optic neuritis, using randomized controlled trials (RCTs). We systematically searched PubMed, PubMed Central (PMC), MEDLINE, Cochrane library, and Scopus databases using regular keywords and medical subject headings terms. Randomized controlled trials of any statin used in any variants of MS, including studies on statins used in optic neuritis published up to April 2021, were included in the review. Data on the effects on the relapse rate, the Expanded Disability Status Scale (EDSS) alterations, and the changes in Magnetic Resonance Imaging (MRI) lesions were collected from the included studies. Seven studies with a total of 831 patients and an average duration of follow-up of six to 36 months were included in our review. Five trials were of statins add-on to interferon therapy in relapsing-remitting multiple sclerosis (RRMS), of which four studies were assessed to be of good quality while the remaining study featured a high risk of bias. One trial of simvastatin monotherapy in Secondary Progressive Multiple Sclerosis (SPMS) was included, which was assessed to be of good methodological quality with low risk of bias and adequate patient number. A trial of simvastatin monotherapy on patients with optic neuritis was included, which was evaluated as a good quality study. Still, it had a low number of participants and a short duration of follow-up. We used the changes in disease relapse rate and EDSS as primary outcome variables and the MRI lesions changes as a secondary outcome variable. Studies in RRMS showed no significant effects on primary and secondary outcomes. The study on SPMS featured a significant improvement in EDSS in simvastatin-treated patients with no effect on relapse rate or MRI changes. Simvastatin use in optic neuritis enhances clinical visual outcomes with no significant effect on MRI changes or the rate of progression to definite MS. In contrast to animal studies and observational studies, randomized controlled trials do not replicate the positive effects of statins used as monotherapy or combined with interferon beta in patients with RRMS and optic neuritis in relapse rate EDSS or MRI changes. However, trials of statins on SPMS showed a promising effect on disability progression (EDSS score), which might support the proposed immune-modulatory and neuroprotective role of statins and serve as a baseline for further RCTs applying statins as monotherapy or combination with other established MS therapies.

Protective Role of Vitamin D Therapy in Diabetes Mellitus Type II.

Diabetes Mellitus type II (DM II) is a worldwide disease with a rapidly growing parallel prevalence and adversities affecting multi-body systems. Hence, it is imperative to treat DM II effectively, maintaining glucose homeostasis to avoid complications such as diabetic nephropathy, peripheral neuropathy, and retinopathy. Vitamin D, among many benefits, has positive outcomes on hemoglobin A1c (HbA1c) control. It aids in insulin secretion and sensitivity. We systematically screened four databases for relevant information; PubMed, Medline, PMC, and Google scholar. Inclusion and exclusion criteria were applied, and quality appraisal was then done using certain checklist tools: Newcastle-Ottawa tool, AMSTAR (A Measurement Tool to Assess Systematic Reviews) checklist, SANRA (Scale for the Assessment of Narrative Review Articles) checklist, and Cochrane bias assessment. Data were collected from 14 articles, of which eight are systematic reviews and meta-analysis, one is a narrative review, five are randomized controlled trials and three are general information about DM II and Vitamin D. In addition, this article evaluates the clinical significance of Vitamin D administration in DM II from a glucose homeostasis perspective, and complications such as nephropathy, neuropathy, and retinopathy. Vitamin D had a clinical positive impact on glucose level, particularly on hemoglobin A1c (HbA1c) reduction, alleviation of diabetic neuropathy and nephropathy symptoms, and hyperglycemia induced-oxidative stress on the retinal cells.

Comparative Pathogenicity of Duck Hepatitis A Virus-1 Isolates in Experimentally Infected Pekin and Muscovy Ducklings.

Duck hepatitis virus (DHV) has always been considered one of the threats endangering duck farming in Egypt since the 1960s. In the current study, suspected DHV samples (n = 30) were obtained from commercial Pekin, Mulard (hybrid), and Muscovy duck farms and backyards in Beheira, Alexandria, Gharbia, Kafr El-Sheikh, and Giza provinces between 2012 and 2017. Diseased 3-21-day-old ducklings showed a clinical history of high mortality rates and nervous signs. Samples were screened by RT-PCR targeting the 5'UTR region and VP1 gene. The PCR-confirmed samples (n = 7) were isolated via allantoic route inoculation onto 9-day-old specific-pathogen-free embryonated chicken eggs. Embryos showed stunting, subcutaneous hemorrhages, and liver necrotic greenish-yellow foci. Duck hepatitis A virus-1 (DHAV-1) isolates were genetically analyzed in comparison to other field and vaccine strains. Phylogenetic analyses of the full-length VP1 gene sequences revealed that the obtained DHAV-1 field isolates clustered into genetic group 4 alongside other Egyptian strains isolated during the same period (95.9-99.72% similarity). Amino acid substitutions in the carboxyl-terminal of VP1 (I180T, G184E, D193N, and M213I) were identified in two strains. Also, deletion mutation at I189 was detected in three DHAV-1 strains. Additionally, the two amino acid residues E205 and N235 were common among the isolated strains and other virulent DHAV-1 strains. Two DHAV-1 isolates originated from Pekin source were selected for conducting the comparative pathogenicity testing based on detected point mutations at C-terminus of VP1. We evaluated the pathogenicity of these isolates by investigating clinical signs, mortality rates, and gross pathological and microscopic lesions. The study revealed that experimentally infected Pekin and Muscovy ducklings showed similar clinical signs including squatting down, lateral recumbency, and spasmodic kicking. Muscovy showed milder pathological changes in the liver compared to Pekin ducklings. Histopathological findings supported the gross pathological lesions detected in both breeds. In conclusion, these data provide updated information on the genetic diversity and pathotyping of Egyptian DHAV-1 strains. To the best of our knowledge, this is the first report of comparative pathogenicity of recent DHAV-1 strains in Pekin and Muscovy ducklings in Egypt and the Middle East region.

The protection afforded to cattle immunized with Theileria annulata infected cell line is enhanced by subunit vaccine candidate TaSP.

Tropical theileriosis constraints the development of the dairy industry in the Sudan and vaccination using live attenuated schizont vaccines is considered a promising measure for its control. The present study was carried out to investigate the ability of recombinant T. annulata surface protein (TaSP) to improve the efficacy of the attenuated Atbara cell line in protecting calves against field challenge. To this end, 23 cross-bred (Friesian × Kenana) calves were divided into four groups. Animals in group 1 (n = 5) were left unvaccinated. Group 2 (n = 6) received the Atbara cell line, animals in group 3 (n = 6) were immunized with three doses of TaSP on days 21, 49 and 77, while animals in group 4 (n = 6) received the cell line vaccine on day 0 and three doses of TaSP in Freund's incomplete adjuvant at days 21, 49 and 77. Twenty-eight days after the last TaSP boost, all groups were challenged by exposing them to natural field tick infestation in a region known to be endemic for tropical theileriosis. No thermal reactions, piroplasms or schizonts were observed in the immunized animals following immunization. Upon challenge, all animals showed a range of symptoms of clinical theileriosis with variable degrees of severity. The application of TaSP alone appeared to have no effect in terms of protection. The efficacy of the cell line alone was lower than the 100% level of protection against mortality observed in the group that received the combined cell line vaccine and TaSP, suggesting a synergistic effect of this combination.

Artesunate plus sulfadoxine-pyrimethamine in the treatment of uncomplicated Plasmodium falciparum malaria during pregnancy in eastern Sudan.

Malaria during pregnancy is associated with serious adverse effects; these could be avoided with effective treatment. Artesunate plus sulfadoxine-pyrimethamine (AS+SP) is a promising antimalarial combination; however, few data are available on its safety during pregnancy. The present study was carried out in New Halfa Hospital, eastern Sudan, between September 2004 and March 2005. Thirty-two pregnant Sudanese women with uncomplicated Plasmodium falciparum malaria were treated with AS+SP at a mean of 29.7 weeks of gestation. The patients were followed-up until delivery and the babies were followed-up until the age of 1 month. The drug was well tolerated, the parasitaemia was cleared and the patients were symptom-free within 2 days. All the patients delivered full-term live babies. One of the babies died on the fourth day; none of the women died and there was no miscarriage, stillbirth, or congenital abnormalities in the newborn babies. Thus, this small descriptive study failed to detect unintended effects of AS+SP during pregnancy.
