In order to identify a quick and reliable technique for accurate diagnosis of malaria, study of the efficiency of the tests such as Parahit total (HRPII & aldolase Ag), Advantage mal card (parasite specific LDH), and modified QBC was done in comparison with conventional blood smear microscopy. One hundred patients infected withP. vivaxand 101 infected withP. falciparumwere included in this study. The sensitivity of Parahit total, Advantage mal card, and modified QBC forP. falciparumdetection was 70.3, 95%, and 98%, and specificity was 98%, 98%, and 96%, respectively. The sensitivity of Parahit total, Advantage mal card, and modified QBC forP. vivaxdetection was 73%, 97.0%, and 98%, respectively, and specificity of all the tests was 98%. On day 15, in falciparum arm, Advantage mal card and Parahit total showed 8 (7.92%) and 59 (58.41%) false positives. On day 15, in vivax arm, Parahit total revealed 52% false positives. The study indicated that modified QBC could be only used where appropriate facilities are available. Advantage mal card was a better follow-up tool than Parahit total.

Abstract Introduction: Anemia is a common problem in patients with inflammatory bowel diseases (IBD), and its etiology is usually multifactorial. It can be produced by chronic blood loss, nutritional deficiencies, and drugs such as salazopyrine; however it can also due to auto immune hemolysis, which is a rare complication of IBD. We report a case of coombs positive autoimmune hemolytic anemia associated with ulcerative colitis both diagnosed at the same presentation. Case Report: A 32 year old man with no significant past medical history presented with complaint of dark colored urine, jaundiced skin and fatigue for 4 weeks. He also reported diarrhea mixed intermittently with blood for last few months. Physical exam was consistent with jaundice and anemia (pallor and icterus) with slightly palpable spleen. Initial lab work up showed Hb of 3.8 with normal platelet and WBC count, high reticulocytes count of 7% .LFT showed serum bilirubin of 3.6 (direct 0.4) with normal serum ALT and AST levels .Serum LDH was high (1032 U/l) while serum haptoglobin was low (0.11 mg/dl). Peripheral smear showed anisopoikilocytosis & spherocytosis. (See Figure 1) Further investigations revealed a positive direct Coombs test consistent with diagnosis of autoimmune hemolytic anemia. CT abdomen and pelvis showed mild splenomegaly & non-specific enlarged mesenteric lymph nodes. Colonoscopy revealed ulcerative pancolitis confirmed by histological findings of biopsies taken. Patient received PRBC transfusions and was started on steroids and mesalamine and was discharged on maintenance dose. His symptoms resolved in 4 weeks and Hb remained stable with no evidence of further hemolysis at 4 month follow up .Repeated CT abdomen & pelvis showed resolution of the lymphadenopathy. Figure 1: Peripheral Blood smear showing anisopoikilocytosis & spherocytosis. Figure 1:. Peripheral Blood smear showing anisopoikilocytosis & spherocytosis. Discussion: Autoimmune hemolytic anemia (AIHA) is a rare complication of IBD. The exact underlying pathogenesis of this association remains obscure; however it has been attributed to the production of cross reacting anti erythrocyte antibodies. In AIHA associated with IBD, corticosteroids are considered to be first line therapy and often cause remission of hemolysis along with treatment for IBD Immunomodulators and splenectomy has been used for patients with refractory AIHA. Colectomy done for fulminant colitis has also been reported to induce remission of AIHA. Further studies for long term follow up and pathogenesis of this association are warranted.

Current Review

In the field of malaria diagnosis much effort is put into the development of faster and easier alternatives to the gold standard, blood smear microscopy. Nucleic acid amplification based techniques pose some of the most promising upcoming diagnostic tools due to their potential for high sensitivity, robustness and user-friendliness. In the current review, we will discuss some of the different DNA-based sensor systems under development for the diagnosis of malaria.

Objective To compare the efficacy of quinine-doxycycline to quinine-clindamycin combination, as treatment for uncomplicated falciparum malaria in children.Methods This randomized open labelled controlled trial was conducted from July to August 2007 at Mandailing Natal, Sumatera Utara Province. The subjects were 8 – 18 year old children with positive Plasmodium falciparum from the peripheral blood smear. Simple randomization was performed to determine subject study into two groups of treatment, one group received quinine-clindamycin and the other received quinine-doxycycline treatment. The parasitemia was counted on day 0, 2, 7 and 28. We also observed the adverse effects of the antimalarial combination.Results Two hundred and forty six children who fulfilled the inclusion criteria were divided into two groups. All subjects completed the study. Cure rate achieved 100% from peripheral blood smear examination at the second day observation and showed no recrudescence at day 28th. (P=0.0001). During 28 days follow up, there were 21 (17.6%) patients suffered from headache, 18 (14.6%) vomit and 40 children (32.5%) suffered from tinnitus in quinine-doxycycline combination, compared to quinine-clindamycin combination group only 4 (3.3%) suffered from headache, 1 (0.8%) suffered from tinnitus and there was no vomiting experience in any patient (P < 0.0001).Conclusion Combination of quinine with either clindamycin or doxycycline are effective as an alternative antimalarial treatment. The combination of quinine-clindamycin is well tolerated than the combination of quinine-doxyciline, and this combination may be particular value for young children and pregnant women, as these two groups cannot receive doxycycline.

Malaria is a major disease in Africa and leads to various public health problems. A study was carried out at the Aviation Medical Clinic Laboratory, Murtala Mohammed Airport, Ikeja, Lagos State, Nigeria, in 2014. The work aimed to determine the prevalence of malaria among patients attending the laboratory. Blood samples were therefore collected from 51 patients and subjected to both blood smear microscopy and a rapid immunochromatographic diagnostic test (SD BIOLINE Malaria Ag) for detection of, respectively, malaria parasites and antigens. At the end of the study, 22% of the patients were detected positive by the microscopic examination while 9.8% were tested positive when using SD BIOLINE Malaria Ag. The outcomes of the study show a high prevalence of malaria at the airport. This represents a serious risk factor leading to a high likelihood of spread and occurrence of malaria in other countries including Western countries whereby the disease is nonendemic. It also pointed out that the blood smear microscopy seems to be better than Rapid Diagnosis Test (RDT) for malaria diagnosis.
