Albumin: Creatinine Ratio during long term Diabetes Mellitus in the Assessment of early Nephropathy in Sudanese Population

Background: Diabetic nephropathy is one of the major causes of chronic renal failure. Microalbuminuria (MAU) has been recognized as an independent and reliable predictor for future development of overt proteinuria in diabetic patients.Objectives: This descriptive cross-sectional study was carried during the period of January-April 2012, in Omdurman Teaching Hospital, to determine Microalbuminuria creatinine ratio, in long term Diabetic patients.Materials and Methods: Immunoturbidmetric method was used to asses’ microalbuminuria in 50 cases (50%) and 50 controls (50%). Ordinary chemical method (Jaffe reaction) was used for the determination of creatinine for both the groups.Results: Microalbuminuria in Diabetic patients showed an increase when compared with the control group with P value 0.000. Similarly creatinine also showed an increase in diabetic patients.Conclusion: It was concluded and is in further affirmation of the previous studies that microalbuminuria should be used as an early indicator for Diabetic Nephropathy. Further studies with 24 hour urine sample are recommended for assessment of Microalbuminuria in long term Diabetic patients, provided that the patients are on a normal diet with regular treatment for diabetes.Key words: Microalbuminuria, Creatinine, Diabetes mellitus, Nephropathy

Biochemical Parameters in Relation to Tuberculosis in Sudanese Patients

Background: Malnutrition and wasting are associated with TB and HIV infection. Malnutrition and tuberculosis are both problems of considerable magnitude in most of the underdeveloped regions of the world. Nutritional status is significantly lower in patients with active tuberculosis compared with healthy controls. Both, protein-energy malnutrition and micronutrients deficiencies increase the risk of tuberculosis.Objectives: To investigate the concentration of serum albumin, total protein, glutamate oxalo acetate transaminase (GOT), glutamate pyruvate transaminase (GPT) and zinc in Sudanese tuberculosis patients (TB), attending the Tropical Diseases Teaching Hospital, Khartoum State.Materials and Methods: The study was performed on 60 tuberculosis patients, compared with 40 healthy individual age and sex matched used as control group .The study period was from April to August 2011. Serum albumin, total protein, GOT and GPT levels were determined by using clinical chemistry analyzer while zinc level was analyzed by atomic absorption spectro-photometers.Results: Among TB patients the mean ±SD of plasma albumin, total protein, GOT, GPT and zinc respectively were 3.29±0.91, 7.55±1.59, 21.24±8.33, 9.12±6.34 and 0.47±0.17. The mean ±SD of plasma albumin, total protein, GOT, GPT and zinc for control group respectively were 4.19±0.93, 8.0±0.98, 26.0±9.08, 13.3±8.15, and 0.55±0.14. Statistically significant association was observed in all parameters between the patients and control group (P<0.05).Conclusions: This study concluded that TB patients had significant decreased levels of all parameters; however albumin and GPT were more significant as compared to others.Keywords: Tuberculosis, Total protein, Albumin, Liver enzymes, Zinc

Knowledge, attitudes and practices among people in Saudi Arabia regarding COVID-19: A cross-sectional study

Background: The general population’s compliance with preventive measures and legislation is mainly influenced by their knowledge level, attitude, and practices. This study assessed the knowledge, attitude, and practices of public residents towards corona virus disease-2019 preventive measures in Saudi Arabia. Design and Methods: This is a cross-sectional study; it used a validated cross-sectional online survey that received responses from 13 Saudi administrative regions. Results: There were 1513 participants who completed the study (55% females; 77.7%, university education). Knowledge level, attitude, and practices towards corona virus disease-2019 were 81.3%, 86.6%, and 81.9%, respectively. The knowledge subscales showed that 1496 (98.9%) participants knew the system targeted by the virus, 96.2% and 97.3% knew the causative agent and symptoms, 783 (52.2%) participants knew the transmission modes, and 696 (46.0%) participants knew about the complications. The attitude subscales included 1465 (96.5%) participants who had dealt with an infected person, 1451 (95.9%) participants who isolated in a health facility, 1195 (97.0%) participants who knew about hand washing, and 1387 (91.7%) participants who thought the virus spread through home delivery. The practice subscales included 1505 (99.5%) participants who properly disposed of gloves and tissues and 1347 (89.0%) participants who reported safe practices when coughing or sneezing.Conclusions: This study showed satisfactory knowledge, attitude, and practice towards corona virus disease-2019 in Saudi Arabia. The educational level is a dominant influencing factor for knowledge, attitude, and practice

The UK register of HIV seroconverters: Methods and analytical issues

A Register of HIV-infected persons who have had a negative antibody test within 3 years of their first antibody positive test (seroconverters) is being set up in the UK to monitor the distribution of times from HIV seroconversion to AIDS (the incubation period) and to death. It will also provide a national resource for use by those designing studies in this group of individuals. Clinicians caring for HIV-positive persons in Genito-Urinary Medicine, Infectious Disease and other departments throughout the UK were asked to participate by providing information on eligible subjects. Most laboratories undertaking HIV antibody testing were also contacted and asked to provide the name of the attending clinician for all seroconverters identified through the HIV laboratory reporting systems of the PHLS Communicable Disease Surveillance Centre (CDSC) and the Scottish Centre for Infection and Environmental Health (SCIEH) and for any other seroconverters known to them but not identified by CDSC or SCIEH. Data items sought for the Register include: sex, ethnic group, probable route of HIV transmission, annual CD4 counts, details of therapy and prophylaxis prescribed, AIDS-defining events and vital status. Follow up information is collected annually. Wherever possible, all seroconverters known to a clinic have been identified, whether currently alive or dead, either from clinic records or laboratory reporting or both. The objective is to establish and update a complete register of seroconverters on a long-term basis to provide reliable estimates of the incubation period on which future projections of AIDS cases in the UK can be made

A novel pathogenic mutation of the CYP27B1 gene in a patient with vitamin D-dependent rickets type 1: a case report

BACKGROUND: Rickets can occur due to Vitamin D deficiency or defects in its metabolism. Three rare genetic types of rickets with different alterations of genes have been reported, including: Vitamin D dependent rickets type 1, Vitamin D dependent rickets type 2 or also known as Vitamin D resistant rickets and 25 hydroxylase deficiency rickets. Vitamin D dependent rickets type 1 is inherited in an autosomal recessive pattern, and is caused by mutations in the CYP27B1 gene encoding the 1α-hydroxylase enzyme. We report here a new mutation in CYP27B1, which lead to Vitamin D dependent rickets type 1. CASE PRESENTATION: We report on a 13-month-old Arabic Saudi girl with Vitamin D dependent rickets type 1 presented with multiple fractures and classic features of rickets. A whole exome sequencing identified a novel pathogenic missense mutation (CYP27B1:Homozygous c.1510C > T(p.Q504X)) which results in a protein truncating alteration. Both parents are heterozygous carriers of the mutation. Based on data search in Human Gene Mutation Database, 63 CYP27B1 alterations were reported: only 28.6% are protein truncating (5 nonsense, 13 frameshift insertions/deletions, 0 gross deletions), while 61.9% are non-truncating (38 missense, 1 small in-frame insertions/deletion), and 9.5% are possible protein-truncating (5 splice, 1 regulatory). CONCLUSION: The deleterious effect of this alteration, which was the only mutation detected in the CYP27B1 common gene of Vitamin D dependent rickets type 1 in the proband, and its autosomal recessive inheritance fashion, both support a pathogenic nature of this mutation as the cause of Vitamin D dependent rickets type 1

A Randomized Open-Label Trial of Artesunate- Sulfadoxine-Pyrimethamine with or without Primaquine for Elimination of Sub-Microscopic P. falciparum Parasitaemia and Gametocyte Carriage in Eastern Sudan

In areas of seasonal malaria transmission, treatment of asymptomatic carriers of malaria parasites, whose parasitaemia persists at low densities throughout the dry season, could be a useful strategy for malaria control. We carried out a randomized trial to compare two drug regimens for clearance of parasitaemia in order to identify the optimum regimen for use in mass drug administration in the dry season.A two-arm open-label randomized controlled trial was conducted during the dry season in an area of distinct seasonal malaria in two villages in Gedarif State in eastern Sudan. Participants were asymptomatic adults and children aged over 6 months, with low-density P. falciparum infection detected by PCR. Participants were randomized to receive artesunate/sulfadoxine-pyrimethamine (AS+SP) combination for three days with or without a dose of primaquine (PQ) on the fourth day. Parasitaemia detected by PCR on days 3, 7 and 14 after the start of treatment and gametocytes detected by RT-PCR on days 7 and 14 were then recorded. 104 individuals who had low density parasitaemia at screening were randomized and treated during the dry season. On day 7, 8.3% were positive by PCR in the AS+SP+PQ group and 6.5% in the AS+SP group (risk difference 1.8%, 95%CI -10.3% to +13.8%). At enrolment, 12% (12/100) were carrying gametocytes. This was reduced to 6.4% and 4.4% by day 14 (Risk difference 1.9% (95%CI -9.3% to +13.2%) in AS+SP+PQ and AS+SP groups, respectively.Addition of primaquine to artemisinin combination treatment did not improve elimination of parasitaemia and prevention of gametocyte carriage in carriers with low-density parasitaemia in the dry season.ClinicalTrials.gov NCT00330902

Increased HIV Incidence in Men Who Have Sex with Men Despite High Levels of ART-Induced Viral Suppression: Analysis of an Extensively Documented Epidemic

Background: There is interest in expanding ART to prevent HIV transmission, but in the group with the highest levels of ART use, men-who-have-sex-with-men (MSM), numbers of new infections diagnosed each year have not decreased as ART coverage has increased for reasons which remain unclear. Methods: We analysed data on the HIV-epidemic in MSM in the UK from a range of sources using an individual-based simulation model. Model runs using parameter sets found to result in good model fit were used to infer changes in HIV-incidence and risk behaviour. Results: HIV-incidence has increased (estimated mean incidence 0.30/100 person-years 1990–1997, 0.45/100 py 1998–2010), associated with a modest (26%) rise in condomless sex. We also explored counter-factual scenarios: had ART not been introduced, but the rise in condomless sex had still occurred, then incidence 2006–2010 was 68% higher; a policy of ART initiation in all diagnosed with HIV from 2001 resulted in 32% lower incidence; had levels of HIV testing been higher (68% tested/year instead of 25%) incidence was 25% lower; a combination of higher testing and ART at diagnosis resulted in 62% lower incidence; cessation of all condom use in 2000 resulted in a 424% increase in incidence. In 2010, we estimate that undiagnosed men, the majority in primary infection, accounted for 82% of new infections. Conclusion: A rise in HIV-incidence has occurred in MSM in the UK despite an only modest increase in levels of condomless sex and high coverage of ART. ART has almost certainly exerted a limiting effect on incidence. Much higher rates of HIV testing combined with initiation of ART at diagnosis would be likely to lead to substantial reductions in HIV incidence. Increased condom use should be promoted to avoid the erosion of the benefits of ART and to prevent other serious sexually transmitted infections

Out-of-Wedlock Pregnancy Among Single Mothers in Khartoum, Sudan: Sociodemographic Characteristics, Causes, and Consequences

Background: Out-of-wedlock childbearing is a global phenomenon that has lifelong consequences on the lives of both mothers and their children. The aim of this study is to identify the sociodemographic characteristics, causes, and consequences of outof- wedlock pregnancy among single mothers in Khartoum, Sudan.Methods: This descriptive, cross-sectional study was conducted at the Mygoma Orphanage Center (MOC) and Shamaa Rehabilitation Center (SRC) using convenience sampling among 200 participants. A validated questionnaire with 25 items was used to collect data. The data were entered into Epi-Data Manager and analyzed using the SPSS. Results: The study found that most of the single mothers in Khartoum who gave birth out of wedlock were young and had just completed their university education. Most of them discovered their pregnancy during the second or third trimester, and nearly half of them did not receive any antenatal care. The majority of the children born to these mothers were preterm and had a low birth weight. Additionally, many mothers reported experiencing social stigma and rejection from their families due to their out-of-wedlock pregnancy. The study also highlighted loneliness, stress, and romantic relations as the main causes of out-of-wedlock pregnancy among single mothers in Khartoum, Sudan.Conclusion: The study provides useful insights into the sociodemographic characteristics, causes, and consequences of out-of-wedlock pregnancy among single mothers in Khartoum, Sudan. Social stigma and lack of support were identified as significant barriers to the reintegration of single mothers and their children into society. Future research should focus on investigating the long-term effects of outof- wedlock pregnancy on mothers and their children

Temporal trends of molecular markers associated with artemether- lumefantrine tolerance/resistance in Bagamoyo district, Tanzania

Background: Development and spread of Plasmodium falciparum resistance to artemisinin-based combination therapy (ACT) constitutes a major threat to recent global malaria control achievements. Surveillance of molecular markers could act as an early warning system of ACT-resistance before clinical treatment failures are apparent. The aim of this study was to analyse temporal trends of established genotypes associated with artemether-lumefantrine tolerance/resistance before and after its deployment as first-line treatment for uncomplicated malaria in Tanzania 2006. Methods: Single nucleotide polymorphisms in the P. falciparum multidrug resistance gene 1 (pfmdr1) N86Y, Y184F, D1246Y and P. falciparum chloroquine transporter gene (pfcrt) K76T were analysed from dried blood spots collected during six consecutive studies from children with uncomplicated P. falciparum malaria in Fukayosi village, Bagamoyo District, Tanzania, between 2004-2011. Results: There was a statistically significant yearly increase of pfmdr1 N86, 184F, D1246 and pfcrt K76 between 2006-2011 from 14% to 61% (yearly OR = 1.38 [95% CI 1.25-1.52] p \u3c 0.0001), 14% to 35% (OR = 1.17 [95% CI 1.07-1.30] p = 0.001), 54% to 85% (OR = 1.21 [95% CI 1.03-1.42] p = 0.016) and 49% to 85% (OR = 1.33 [95% CI 1.17-1.51] p \u3c 0.0001), respectively. Unlike for the pfmdr1 SNP, a significant increase of pfcrt K76 was observed already between 2004-2006, from 26% to 49% (OR = 1.68 [95% CI 1.17-2.40] p = 0.005). From 2006 to 2011 the pfmdr1 NFD haplotype increased from 10% to 37% (OR = 1.25 [95% CI 1.12-1.39] p \u3c 0.0001), whereas the YYY haplotype decreased from 31% to 6% (OR = 0.73 [95% CI 0.56-0.98] p = 0.018). All 390 successfully analysed samples had one copy of the pfmdr1 gene. Conclusion: The temporal selection of molecular markers associated with artemether-lumefantrine tolerance/resistance may represent an early warning sign of impaired future drug efficacy. This calls for stringent surveillance of artemether-lumefantrine efficacy in Tanzania and emphasizes the importance of molecular surveillance as a complement to standard in vivo trials. © 2013 Malmberg et al.; licensee BioMed Central Ltd
