Management of Helicobacter pylori among medical doctors working in Khartoum, Sudan 2019: a cross-sectional study
Background: Various international guidelines have been developed regarding Helicobacter pylori (H. pylori) management, as it is infecting more than half of the world's population. Sudan's health system lacks guidelines regarding H. pylori management, leading to a discrepancy in practice. Investigating the current approach could be a step forward in the formulation of a national consensus in the management of H. pylori.
Methods: A cross-sectional study was conducted among medical doctors currently working in Khartoum, Sudan. Participants were enrolled from platforms of medical associations through an online questionnaire. The questionnaire was scored out of 25 points, and scoring 13 or above considered a good approach. Data analysis was carried out using Statistical Package for Social Sciences (SPSS).
Results: A total of 358 medical doctors participated in the study. The mean (±SD) score was 12.9(±4.5). Those who were using textbooks, campaigns, symposiums or general medical information to their primary Source of knowledge significantly scored higher. The most selected indication for both diagnosis (76.8%) and treatment (67.6%) was an active peptic ulcer. Stool antigen test (SAT) was the most preferred test (70.7%). The majority of respondents selected triple therapy (82.1%) as a first-line regimen. Only 37.7% confirmed the eradication after four weeks of stopping the treatment. They ensure eradication mainly through SAT (29%).
Conclusion: A suboptimal approach was noted among medical doctors of Khartoum, Sudan, regarding H. pylori management. Efforts should be invested in forming national guidelines and the implementation of continuous medical education programs.

Impact on core values of family medicine from a 2-year Master's programme in Gezira, Sudan: observational study
Background: Training of family physicians should include not only clinical and procedural skills, but also core values as comprehensive care, continuity of care, leadership and patient-centeredness. The Gezira Family Medicine Project (GFMP) is a 2 years Master’s programme in family medicine in Sudan. We assessed the impact of GFMP on the candidates’ adherence to some core values of family medicine. Methods: This is a prospective study with before-after design based on repeated surveys. We used Patient-Practitioner Orientation Scale (PPOS) to assess physicians’ attitude towards patient-centeredness. Practice based data from individual patients’ consultations and self-assessment methods were used to assess physicians’ adherence to core values. Results: At the end of the programme the candidates (N = 110) were significantly more active in community health promotion (p < 0.001), more confident as a team leader (p = 0.008), and showed increased adherence to national guidelines for managing diabetes (p = 0.017) and hypertension (p = 0.003). The responding candidates had more knowledge about patients’ medical history (p < 0.001), family history (p < 0.001) and family situation (p < 0.001). There were more planned follow up consultations (p < 0.001) and more referrals (p = 0.040). In contrast, results from PPOS showed slightly less orientation towards patient-centeredness (p = 0.007). Conclusions: The GFMP Master’s programme induced a positive change in adherence to several core values of family medicine. The candidates became less patient-centered.publishedVersio
Strategic analysis of the obstetric and gynaecological internship in Sudan
Background: The high expectations of the increasingly questioning society lays a great burden on the first line treating doctors in Sudan. This is particularly true in the obstetrics and gynaecology departments. The impact of training of the house-officer in surgical departments was not studied before in Sudan.The aim: To evaluate the gains in knowledge and skills of house-officers in the obstetrics and gynaecology departments as reflected by their activities and their opinions.Methodology: A prospective cohort carried in the period from May 2011 through June 2011. The data was collected from 200 house-officers. Their activities and duties as formulated by their seniors and supervisors and gains in knowledge and skills were noted.Results: All house-officers participated actively in the clinical diagnosis (history, physical examination and relevant investigations) and management of cases of antepartum and postpartum haemorrhages. Of them 186(93%) had duties not more than twice a week. However, 121(60.5%) shared training opportunities in units having seven or less peers. Also, 109(54.5%) had regular seminars and tutorials. In practice, 165(82.5%) performed evacuations, 158(79%) participated in normal deliveries, and 110(55%) were assisted in performing caesarean sections.Conclusion: The overall performance of house-officers in the department of obstetrics and gynaecology in Sudan is good. However, standards of training need to revisited to fill gabs in training if these young doctors are to be dispatched to rural hospital immediately after the internshipperiod.Key words: Internship, preregistration medical graduates duties, house-officers, obstetrics and gynaecology, medical education, and medical responsibility
Self-reported fever, treatment actions and malaria infection prevalence in the northern states of Sudan
BACKGROUND: The epidemiology of fevers and their management in areas of low malaria transmission in Africa is not well understood. The characteristics of fever, its treatment and association with infection prevalence from a national household sample survey in the northern states of Sudan, an area that represents historically low parasite prevalence, are examined in this study. METHODS: In October-November 2009, a cluster sample cross-sectional household malaria indicator survey was undertaken in the 15 northern states of the Sudan. Data on household assets and individual level information on age, sex, whether the individual had a fever in the last 14 days and on the day of survey, actions taken to treat the fever including diagnostic services and drugs used and their sources were collected. Consenting household members were asked to provide a finger-prick blood sample and examined for malaria parasitaemia using a rapid diagnostic test (RDT). All proportions and odds ratios were weighted and adjusted for clustering. RESULTS: Of 26,471 respondents 19% (n = 5,299) reported a history of fever within the last two weeks prior to the survey and 8% had fever on the day of the survey. Only 39% (n = 2,035) of individuals with fever in last two weeks took any action, of which 43% (n = 875) were treated with anti-malarials. About 44% (n = 382) of malaria treatments were done using the nationally recommended first-line therapy artesunate+sulphadoxine-pryrimethamine (AS+SP) and 13% (n = 122) with non-recommended chloroquine or SP. Importantly 33.9% (n = 296) of all malaria treatments included artemether monotherapy, which is internationally banned for the treatment of uncomplicated malaria. About 53% of fevers had some form of parasitological diagnosis before treatment. On the day of survey, 21,988 individuals provided a finger-prick blood sample and only 1.8% were found positive for Plasmodium falciparum. Infection prevalence was higher among individuals who had fever in the last two weeks (OR = 3.4; 95%CI = 2.6 - 4.4, p < 0.001) or reported fever on the day of survey (OR = 6.2; 95%CI = 4.4 - 8.7, p < 0.001) compared to those without a history of fever. CONCLUSION: Across the northern states of the Sudan, the period prevalence of fever is low. The proportion of fevers that are likely to be malaria is very low. Consequently, parasitological diagnosis of all fevers before treatment is an appropriate strategy for malaria case-management. Improved regulation and supervision of health workers is required to increase the use of diagnostics and remove the practice of prescribing artemisinin monotherapy
Artesunate plus sulfadoxine-pyrimethamine for treatment of uncomplicated Plasmodium falciparum malaria in Sudan
BACKGROUND: Early diagnosis and effective treatment with an appropriate drug form the main components of the World Health Organization's strategy to reduce malaria related mortality. The few available drugs might be safeguarded if combined with artesunate. The addition of artesunate to a standard antimalarial treatment substantially reduces treatment failure, recrudescence and gametocyte carriage. METHODS: During late 2004, the efficacy of artesunate (4 mg/kg. day, on days 0–2) plus sulfadoxine-pyrimethamine (25 mg/kg, on day 0) for the treatment of uncomplicated Plasmodium falciparum malaria was investigated in four sentinel areas in Sudan, with different malaria transmission (Damazin, Kassala, Kosti, and Malakal). RESULTS: Two hundreds and sixty-nine patients completed the 28-day follow-up. On day one, 60 (22.3%) patients were febrile and 15 (5.5%) patients were parasitaemic. On day three, all the patients were afebrile and aparasitaemic. While two patients (0.7%, Kassala) showed late Clinical and Parasitological Failures, the rest (99.3%) of the patients demonstrated Adequate Clinical and Parasitological Response. A gametocytaemia were detected during the follow-up in one patient (0.37%, Kassala). Adverse drug effects were detected in 32 (11.9%) patients CONCLUSION: The study showed that AS plus SP is an effective, safe drug in the treatment of uncomplicated P. falciparum malaria in Sudan
Fluorescence microscope (Cyscope®) for malaria diagnosis in pregnant women in Medani Hospital, Sudan
<p>Abstract</p> <p>Background</p> <p>Accuracy of diagnosis is the core for malaria control. Although microscopy is the gold standard in malaria diagnosis, its reliability is largely dependent on user skill. We compared performance of Cyscope<sup>® </sup>fluorescence microscope with the Giemsa stained light microscopy for the diagnosis of malaria among pregnant women at Medani Hospital in Central Sudan. The area is characterized by unstable malaria transmission.</p> <p>Methods</p> <p>Socio-demographic characteristics and obstetrics history were gathered using pre-tested questionnaires. Blood samples were collected from febrile pregnant women who were referred as malaria case following initial diagnosis by general microscopist.</p> <p>Results</p> <p>During the study period 128 febrile pregnant women presented at the hospital. Among them, <it>Plasmodium falciparum </it>malaria was detected in 82 (64.1%) and 80 (62.5%) by the Giemsa-stained light microscopy and the Cyscope<sup>® </sup>fluorescence microscope, respectively. The sensitivity of the Cyscope<sup>® </sup>fluorescence microscope was 97.6% (95% CI: 92.2%-99.6%). Out of 46 which were negative by Giemsa-stained light microscopy, 5 were positive by the Cyscope<sup>® </sup>fluorescence microscope. This is translated in specificity of 89.1% (95% CI: 77.5%-95.9%). The positive and negative predictive value of Cyscope<sup>® </sup>fluorescence microscope was 94.1% (95% CI: 87.4% -97.8%) and 95.3% (95% CI: 85.4% - 99.2%), respectively.</p> <p>Conclusion</p> <p>This study has shown that Cyscope<sup>® </sup>fluorescence microscope is a reliable diagnostic, sensitive and specific in diagnosing <it>P. falciparum </it>malaria among pregnant women in this setting. Further studies are needed to determine effectiveness in diagnosing other <it>Plasmodium </it>species and to compare it with other diagnostic tools e.g. rapid diagnostic tests and PCR.</p

Testing the sensitivity and specificity of the fluorescence microscope (Cyscope®) for malaria diagnosis
<p>Abstract</p> <p>Background</p> <p>Early diagnosis and treatment of malaria are necessary components in the control of malaria. The gold standard light microscopy technique has high sensitivity, but is a relatively time-consuming procedure especially during epidemics and in areas of high endemicity. This study attempted to test the sensitivity and specificity of a new diagnostic tool - the Cyscope<sup>® </sup>fluorescence microscope, which is based on the use of Plasmodium nucleic acid-specific fluorescent dyes to facilitate detection of the parasites even in low parasitaemia conditions due to the contrast with the background.</p> <p>Methods</p> <p>In this study, 293 febrile patients above the age of 18 years attending the malaria treatment centre in Sinnar State (Sudan) were interviewed using a structured questionnaire. Finger-prick blood samples were also collected from the participants to be tested for malaria using the hospital's microscope, the reference laboratory microscope, as well as the Cyscope<sup>® </sup>microscope. The results of the investigations were then used to calculate the sensitivity, specificity, and positive and negative predictive values of the Cyscope<sup>® </sup>microscope in reference to gold standard light microscopy.</p> <p>Results</p> <p>The sensitivity was found to be 98.2% (95% CI: 90.6%-100%); specificity = 98.3% (95% CI: 95.7% - 99.5%); positive predictive value = 93.3% (95% CI: 83.8% - 98.2%); and negative predictive value = 99.6% (95% CI: 97.6% - 100%).</p> <p>Conclusions</p> <p>In conclusion, the Cyscope<sup>® </sup>microscope was found to be sensitive, specific and provide rapid, reliable results in a matter of less than 10 minutes. The Cyscope<sup>® </sup>microscope should be considered as a viable, cheaper and time-saving option for malaria diagnosis, especially in areas where <it>Plasmodium falciparum </it>is the predominant parasite.</p
Feasibility and acceptability of home-based management of malaria strategy adapted to Sudan's conditions using artemisinin-based combination therapy and rapid diagnostic test
<p>Abstract</p> <p>Background</p> <p>Malaria remains a major public health problem especially in sub-Saharan Africa. Despite the efforts exerted to provide effective anti-malarial drugs, still some communities suffer from getting access to these services due to many barriers. This research aimed to assess the feasibility and acceptability of home-based management of malaria (HMM) strategy using artemisinin-based combination therapy (ACT) for treatment and rapid diagnostic test (RDT) for diagnosis.</p> <p>Methods</p> <p>This is a study conducted in 20 villages in Um Adara area, South Kordofan state, Sudan. Two-thirds (66%) of the study community were seeking treatment from heath facilities, which were more than 5 km far from their villages with marked inaccessibility during rainy season. Volunteers (one per village) were trained on using RDTs for diagnosis and artesunate plus sulphadoxine-pyrimethamine for treating malaria patients, as well as referral of severe and non-malaria cases. A system for supply and monitoring was established based on the rural health centre, which acted as a link between the volunteers and the health system. Advocacy for the policy was done through different tools. Volunteers worked on non-monetary incentives but only a consultation fee of One Sudanese Pound (equivalent to US$0.5).</p> <p>Pre- and post-intervention assessment was done using household survey, focus group discussion with the community leaders, structured interview with the volunteers, and records and reports analysis.</p> <p>Results and discussion</p> <p>The overall adherence of volunteers to the project protocol in treating and referring cases was accepted that was only one of the 20 volunteers did not comply with the study guidelines. Although the use of RDTs seemed to have improved the level of accuracy and trust in the diagnosis, 30% of volunteers did not rely on the negative RDT results when treating fever cases. Almost all (94.7%) the volunteers felt that they were satisfied with the spiritual outcome of their new tasks. As well, volunteers have initiated advocacy campaigns supported by their village health committees which were found to have a positive role to play in the project that proved their acceptability of the HMM design. The planned system for supply was found to be effective. The project was found to improve the accessibility to ACTs from 25% to 64.7% and the treatment seeking behaviour from 83.3% to 100% before- and after the HMM implementation respectivly.</p> <p>Conclusion</p> <p>The evaluation of the project identified the feasibility of the planned model in Sudan's condition. Moreover, the communities as well as the volunteers found to be satisfied with and supportive to the system and the outcome. The problem of treating other febrile cases when diagnosis is not malaria and other non-fever cases needs to be addressed as well.</p
Ethical, legal and social aspects of the approach in Sudan
The global malaria situation, especially in Africa, and the problems frequently encountered in chemical control of vectors such as insecticide resistance, emphasize the urgency of research, development and implementation of new vector control technologies that are applicable at regional and local levels. The successful application of the sterile insect technique (SIT) for the control of the New World screwworm Cochliomyia hominivorax and several species of fruit flies has given impetus to the use of this method for suppression or elimination of malaria vectors in some areas of Africa including Northern State of Sudan. The research and development phase of the Northern State feasibility study has been started. Sudanese stakeholders are working side-by-side with the International Atomic Energy Agency in the activities of this important phase. Several ethical, legal and social issues associated with this approach arose during this phase of the project. They need to be seriously considered and handled with care. In this paper, these issues are described, and the current and proposed activities to overcome potential hurdles to ensure success of the project are listed
