Background: 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®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.Methods: 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.Results: During the study period 128 febrile pregnant women presented at the hospital. Among them, Plasmodium falciparum malaria was detected in 82 (64.1%) and 80 (62.5%) by the Giemsa-stained light microscopy and the Cyscope®fluorescence microscope, respectively. The sensitivity of the Cyscope®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®fluorescence microscope. This is translated in specificity of 89.1% (95% CI: 77.5%-95.9%). The positive and negative predictive value of Cyscope®fluorescence microscope was 94.1% (95% CI: 87.4% -97.8%) and 95.3% (95% CI: 85.4% - 99.2%), respectively.Conclusion: This study has shown that Cyscope®fluorescence microscope is a reliable diagnostic, sensitive and specific in diagnosing P. falciparum malaria among pregnant women in this setting. Further studies are needed to determine effectiveness in diagnosing other Plasmodium species and to compare it with other diagnostic tools e.g. rapid diagnostic tests and PCR. © 2011 Hassan et al; licensee BioMed Central Ltd.

Anaemia is a widespread problem in many parts of the world especially in tropic areas. Among pregnant women, it has negative consequences on maternal and perinatal outcomes. A cross-sectional study was conducted to investigate the prevalence of anaemia, iron, zinc and copper deficiencies among pregnant women in Wad Medani hospital, central Sudan and to examine the relationship of these micronutrients with haemoglobin (Hb) levels. One hundred four (52.5%) out of 200 pregnant women had anaemia (Hb < 11 gm/dl) and 3 (1.5) % had severe anaemia (Hb < 7 gm/dl). Iron deficiency (S-ferritin < 15 μg/l), iron deficiency anaemia (<11 gm/dl and S-ferritin < 15 μg/l) were prevalent in 25 (12.5%) and 13 (6.5%) of these women, respectively. Ninety (45.0%) and eight (4.0%) of these women had zinc (<80 μg/ml) and copper (<80 μg/ml) deficiency, respectively. In 24 (12.0%) of these women, there were ≥2 deficiencies of these elements. S-copper was significantly lower in patients with anaemia. While age, parity, gestational age, ferritin, zinc and copper were not predictors for anaemia, women who practiced pica were at higher risk for anaemia (OR = 3.4, 95% CI = 1.4-7.9, P = 0.004). Gestational age was significantly inversely correlated with haemoglobin (r = 0.161, P = 0.03), S-ferritin (r = 0.285, P = 0.001) and S-zinc (r = 0.166, P = 0.02). Thus, dietary and supplement interventions are required to prevent and control anaemia in this setting. Further research is needed. © 2009 Springer Science+Business Media, LLC.

A retrospective case-control study was conducted to investigate the risk factors for pre-eclampsia - including the protective effect of placenta previa - at Medani Maternity Hospital, Sudan. Medical files of the patients during the period 2003-2010 were reviewed for age, parity, education level, prenatal care, placenta previa, and hemoglobin level. Women with pre-eclampsia were the cases, and women with normal pregnancy were the controls. There were 54,339 singleton deliveries and 1765 women with pre-eclampsia in the hospital, giving the incidence of pre-eclampsia of 3.2%. The risk factors for pre-eclampsia were; women with age >35 years (OR = 1.4, 95% CI: 1.1-1.8), primiparity (OR = 3.3, 95% CI: 2.7-4.0), para >5 (OR = 3.1, 95% CI: 2.4-4.0), and anemia (OR = 3.3, 95% CI: 2.8-3.9). The risk of pre-eclampsia was inversely increased with education level and prenatal care attendance. The prevalence of placenta previa was 0 (0%) and 55 (3.3%), P < 0.001 in pre-eclamptic and control women, respectively. Placenta previa was a significant protective factor of pre-eclampsia (OR = 0.3, 95% CI: 0.1-0.7). Although, the socio-demographic risk factors for pre-eclampsia observed among women at Medani hospital were similar to those found in other settings; placenta previa was associated with decreased incidence of pre-eclampsia. © 2013 Adam, Haggaz, Mirghani and Elhassan.

Introduction: Both malaria and anaemia have adverse effects on maternal and perinatal outcomes. Thus there is an urgent need to investigate the co-epidemiology of malaria and anaemia and their combined impact on maternal and perinatal outcomes in the different regions of Sudan Methodology: Various cross-sectional and case control studies conducted during the years 2003-2010 to investigate the epidemiology of malaria and anaemia and their impact on maternal and perinatal outcomes in different regions of Sudan were compared. Results: While 13.7% of antenatal attendants in New Halfa had peripheral microscopically detected Plasmodium falciparum malaria, placental malaria (using histological examinations) was prevalent in 32.0-40% and 19.5% of parturient women in New Halfa and Gadarif Hospitals, respectively. Malaria was a risk factor for anaemia in New Halfa and for stillbirths in Omdurman Maternity Hospital. Anaemia was present in 52.5%, 62.6% and 80.2% of pregnant women in Medani, New Halfa, and Gadarif Hospitals, respectively. In Gadarif, 57.3% of pregnant women had a folate deficiency, while 1% had a vitamin B12, deficiency. In Medani, zinc and copper deficiencies were detected in 45.0% and 4% of pregnant women, respectively. Anaemia was a risk factor for low birth weight in Al-Fashir, for fetal anaemia in New Halfa, and for stillbirth in Kassala Hospital. Conclusion: More care should be taken to ensure proper nutrition and malaria prevention such as bed nets and intermittent preventive treatments to avoid these diseases and their effects on maternal and perinatal outcomes. © 2011 Adam et al.

Background: Microscopic examination using Giemsa-stained thick blood films remains the reference standard for detection of malaria parasites and it is the only method that is widely and practically available for quantifying malaria parasite density. There are few published data (there was no study during pregnancy) investigating the parasite density (ratio of counted parasites within a given number of microscopic fields against counted white blood cells (WBCs) using actual number of WBCs. Methods. Parasitaemia was estimated using assumed WBCs (8,000), which was compared to parasitaemia calculated based on each woman's WBCs in 98 pregnant women with uncomplicated Plasmodium falciparum malaria at Medani Maternity Hospital, Central Sudan. Results: The geometric mean (SD) of the parasite count was 12,014.6 (9,766.5) and 7,870.8 (19,168.8) ring trophozoites /μl, P <0.001 using the actual and assumed (8,000) WBC count, respectively. The median (range) of the ratio between the two parasitaemias (using assumed/actual WBCs) was 1.5 (0.6-5), i e, parasitaemia calculated assuming WBCs equal to median (range) 1.5 (0.6-5) times higher than parasitaemia calculated using actual WBCs. There were 52 out of 98 patients (53%) with ratio between 0.5 and 1.5. For 21 patients (21%) this ratio was higher than 2, and for five patients (5%) it was higher than 3. Conclusion: The estimated parasite density using actual WBC counts was significantly lower than the parasite density estimated using assumed WBC counts. Therefore, it is recommended to use the patient's actual WBC count in the estimation of the parasite density. © 2014 Haggaz et al.; licensee BioMed Central Ltd.

Background: Pregnant women are more susceptible to severe Plasmodium falciparum malaria, which can lead to poor maternal and fetal outcomes. Few data exist on the epidemiology of severe P. falciparum malaria in pregnant women. A hospital-based study was carried out to assess the pattern of severe P. falciparum malaria among pregnant women at the Kassala and Medani maternity hospitals, which are located in areas of unstable malaria transmission, in eastern and central Sudan, respectively. Pre-tested questionnaires were used to gather socio-demographic, clinical and obstetrical data. Suitable tests were performed for clinical and biochemical investigations. Results: Among 222 pregnant women diagnosed with malaria at the two hospitals, 40 (18.0%) women at mean (SD) gestational age of 29.3 (6.7) weeks fulfilled one or more of the WHO criteria for severe P. falciparum malaria. These were hypoglycaemia (14; 35.5%), severe anaemia (12; 30%), hypotension (10; 25%), jaundice (9; 22.5%), cerebral malaria (6; 15%), repeated convulsions (4; 10%), hyperparasitaemia (4; 10.0%) and more than one manifestation (9; 22.5%). While the mean (SD) presenting temperature was significantly lower for women presenting with hypoglycaemia [38.2(0.6) versus 38.8(0.7) °C, P = 0.04], other clinical and biochemical characteristics were not significantly different among women with different manifestations of severe P. falciparum malaria. Conclusion: Preventive measures for pregnant women such as insecticide-treated bednets and chemoprophylaxis may be beneficial in areas of unstable malaria transmission. Early detection and prompt treatment of severe malaria, especially in pregnant women with hypoglycaemia, are needed. © 2011 Ali et al; licensee BioMed Central Ltd.

Objective: To investigate the accuracy of malaria diagnosis among pregnant women admitted in Medani Maternity Hospital, Central Sudan during June-October 2009 and to investigate the antimalarials prescribed in this setting. Methods: Socio-demographic characteristics and obstetrics history were gathered using pre-tested questionnaires. The finger prick blood samples were collected from pregnant women who admitted as malaria case after an initial microscopic test done by general microscopists for malaria diagnosis. The antimalarial treatment prescribed by treating doctor was inquired for. Results: Only 21 (8.6%) out of 243 pregnant women admitted as malaria case after an initial microscopic test done by general microscopists for malaria were found to have blood film positive. There was no significant difference in the specificity of the microscopy accuracy between those who have been investigated in the private and governmental sector, 15/193 (8.2%) vs. 6/60(10%), (P >0.05). Quinine infusion was the prescribed drug in this setting. Conclusions: There is a very poor specificity of malaria microscopy in pregnant women admitted to Madani Maternity Hospital. Quinine was the drug received. Malaria control programme should interfere urgently to change this situation. © 2010.
