Abstract

Abstract: Pulmonary TB is still a threat included in top 10 causes of death in the world. Limitation in diagnostic methods is one of the obstacles in improving the detection of pulmonary TB cases. WHO recommend Loop-Mediated Isothermal Amplification (TB-LAMP) with sensitivity, specificity, high efficiency, fast, and simple in terms of molecular method to identify Mycobacterium tuberculosis. This study was aimed to find out whether LAMP-TB could detect M. tuberculosis in the sputum samples. This was a descriptive observational/survey study using a diagnostic test with a cross-sectional design. Samples were patients suspected as pulmonary TB with negative result in sputum smear microscopy at Prof. Dr. R. D. Kandou Hospital Manado during September until October 2017. The results obtained 25 samples of patients suspected pulmonary TB with negative result in sputum smear microscopy. Most of them were at the age of 52-64 years, male (18 people; 72%), and had purulent sputum (14 samples; 56%). Examination by using LAMP-TB obtained 4 samples (16%) stated as positive M. tuberculosis and 21 samples (84%) stated as negative M. tuberculosis. Conclusion: TB-LAMP could detect Mycobacterium tuberculosis in the sputum samples.Keywords: pulmonary TB, M.tuberculosis, TB-LAMP Abstrak: TB Paru saat ini masih menjadi ancaman dan termasuk 10 besar penyebab kematian teratas di dunia.

Abstract

Abstract: Malaria is a very dominant infectious disease in the tropical and subtropical areas which can lead to death of more than a million people every year. Malaria is caused by infection of the protozoan parasite of the genus Plasmodium. Symptoms of malaria are not specific, such as headache, weakness, fatigue, abdominal discomfort, as well as muscle and joint pain, usually followed by fever, chills, sweating, anorexia, vomiting, and worsening malaise. Malaria control requires an integrated approach as follows: prevention (primary vector control) and immediate treatment with effective antimalarial drugs. This study aimed to determine the knowledge of malaria of villagers Tombatu I subdistrict Tombatu Southeast Minahasa District. This was a descriptive study with a cross-sectional design by using questionnaire. The study involved 95 respondents: 46 males (48.4%) and 49 females (51.6%). Ages of the majority were more than 41 years (57.9%), most were high school educated (45.2 %), and most were housewives (46.3%). Resources of malaria were obtained from TV/ Electronic Media (66.7%). Approximately 21% respondents knew that the cause of malaria spreading was Anopheles species and as much as 50.9% knew that mosquitoes bit at night. A total of 34.5% of respondents chose that puddles were breeding places of mosquitoes. A total of 42.2% of respondents knew that chills and fever were the symptoms of malaria. A total of 36.4% of respondents chose that the way of prevention was using mosquito nets. Conclusion: Knowledge about malaria transmission was good but about the species that caused malaria, the biting behavior of mosquitoes spreading malaria, and malaria breeding places was still poor.Keywords: malaria, Anopheles mosquito species, knowledge of malaria.Abstrak: Malaria merupakan penyakit menular yang sangat dominan didaerah tropis dan subtropis yang dapat menyebabkan kematian lebih dari sejuta manusia setiap tahunnya.

Abstract

Abstract: Malaria is classified as one of the infectious diseases that is very dangerous and can cause death. It is caused by parasites that live and thrive in human red blood cells. The disease is not just a problem in developing countries but also in developed countries. As an infectious disease, one of malaria clinical symptoms is fever. Theoretically, it is stated that TNF-α belongs to the cytokines that can cause fever. This was a descriptive study. The body temperatures of patients with malaria fever were measured and the levels of serum TNF-α were examined by using the ELISA method. There were 40 samples obtained by using simple random sampling. The results showed that moderate level of TNF-α (100-500 pg/ml) was found in 36 samples (90%); low level of TNF-α (<100 pg/ml) in 4 samples (10%); meanwhile high level of TNF-α was not found (0%). The data showed that although in most samples the increased body temperatures were associated by the increased TNF-α levels, this condition was not found in all samples Conclusion: In general, the levels of TNF-α increased in patients with malaria fever.Keywords: TNF-α, malaria, fever  Abstrak: Malaria tergolong sebagai salah satu penyakit infeksi yang sangat berbahaya dan dapat menyebabkan kematian. Penyakit ini bukan hanya menjadi masalah di negara berkembang, namun juga di negara-negara maju. Malaria disebabkan oleh parasit yang hidup dan berkembang dalam sel darah merah manusia. Sebagai penyakit infeksi, malaria memiliki gejala-gejala klinis, salah satunya ialah demam. Dikatakan bahwa TNF-α merupakan sejenis sitokin yang menyebabkan terjadinya demam. Penelitian ini bersifat deskriptif dengan sampel sejumlah 40 penderita malaria yang diambil secara simple random sampling. Dalam penelitian ini dilakukan pengukuran suhu tubuh penderita malaria yang disertai demam dan kadar serum TNF-α dengan menggunakan metode ELISA. Hasil penelitian memperlihatkan bahwa kadar TNF-α sedang (100-500 pg/ml) ditemukan pada 36 sampel (90%), kadar rendah (<100 pg/ml) pada 4 sampel (10%), sedangkan kadar tinggi tidak ditemukan (0%). Data yag diperoleh memperlihatkan bahwa walaupun pada sebagian besar kasus peningkatan suhu tubuh disertai dengan peningkatan kadar serum TNF-α, namun kondisi ini tidak berlaku bagi seluruh sampel. Simpulan: Kadar TNF-α umumnya meningkat pada penderita malaria yang mengalami demam.Kata kunci: TNF-α, malaria, demam

Abstract

Abstract: Malaria is still a health problem in the world, especially in undeveloped countries. This disease is caused by protozoa of the genus Plasmodium and has two ways of transmission, naturally (Anopheles spp.) and unnaturally. WHO mentioned that in 2006 there were as many as 200-300 million cases of clinical malaria with 880,000 deaths. In 2012, it was recorded that there were a total of 8,691 malaria cases in North Sulawesi, Indonesia. Therefore, an early diagnostic tool with high sensitivity and specificity is needed. This study aimed to compare the sensitivity and specificity in detection of Plasmodium spp by using thick blood smear method to Polymerase Chain Reaction (PCR). This was a diagnostic test using blood samples of 30 malaria patients at Budi Mulia Hospital and Manembo-nembo Hospital Bitung from September 2013 - January 2014. Thick blood smears were prepared and microcopically tested, then the specimens were scrapped and be further tested by using the PCR. The microscopic test showed 20 positive samples meanwhile the PCR showed 24 positive samples. A diagnostic test using predictive table 2x2 indicated that the PCR had 100% sensitivity in general, 60% specifity, 83.3% positive predictive value, and 100% negative predictive value. Conclusion: Compared to the thick blood smear, the PCR was more accurate in detecting plasmodia in malaria cases with a moderate specificity value and a high sensitivity value.Keywords: thick blood smear, Polymerase Chain Reaction (PCR), sensitivity, specificity  Abstrak: Malaria merupakan salah satu penyakit yang masih menjadi masalah kesehatan di dunia terutama di negara-negara yang belum berkembang. Malaria disebabkan oleh protozoa dari genus Plasmodium dan ditularkan melalui dua cara yaitu alamiah melalui nyamuk Anopheles spp. dan tidak alamiah. WHO melaporkan bahwa pada 2006 terdapat 200-300 juta kasus malaria dengan 880.000 kematian. Di Provinsi Sulawesi Utara, Indonesia, dilaporkan total kasus malaria tahun 2012 sebesar 8.691. Oleh karena itu diperlukan suatu alat diagnostik dini dengan sensitivitas dan spesifisitas yang baik. Penelitian ini bertujuan untuk membandingkan tingkat sensitivitas dan spesifisitas hasil deteksi Plasmodium spp antara cara pemeriksaan mikroskopik tetesan darah tebal dan teknik Polymerase Chain Reaction (PCR). Penelitian ini merupakan uji diagnostik dengan sampel darah dari 30 pasien malaria di RS Budi Mulia dan RS Manembo-nembo Bitung sejak September 2013 - Januari 2014. Setelah disiapkan tetesan darah tebal, dilakukan pemeriksaan mikroskopik. Selanjutnya, spesimen darah dikerok dan diperiksa dengan PCR. Hasil pemeriksaan mikroskopik menunjukkan 20 sampel positif malaria sedangkan pemeriksaan PCR 24 sampel positif malaria. Tes uji diagnostik dengan tabel prediktif 2x2 mendapatkan tingkat sensitivitas PCR secara umum sebesar 100%, spesifisitas 60%, nilai duga positif 83,33%, dan nilai duga negatif 100%. Simpulan: Dibandingkan tetesan darah tebal, pemeriksaan PCR dapat mendeteksi secara lebih akurat adanya plasmodia pada kasus malaria, dengan nilai spesifitas sedang dan nilai sensitivitas tinggi.Kata kunci: tetesan darah tebal, Polymerase Chain Reaction (PCR), sensitivitas, spesifisitas

Abstract

Indonesia is still included in high endemic area of malaria infection. Early detection as well as appropriate and quick treatment is needed to be able to prevent and treat malaria in Indonesia. Laboratory examination using a microscopic method is still used as the gold standard to diagnose malaria cases. However, the morphology similarity of some Plasmodium species and the number of parasites that can be seen under microscopy causes malaria diagnosis become difficult if only relying on microscopy diagnostic method. The purpose of this study is to analyze the sensitivity and specificity of nested PCR compared to microscopic examination in diagnosing malaria cases. A cross-sectional study has been carried out in some areas of Indonesia and the microscopic analysis as well as nest PCR was done in Laboratory of Parasitology and Laboratory of Central Biomedical Faculty of Medicine, Universitas Brawijaya, Malang East Java Indonesia. A total of 149 blood samples from patients with clinical symptoms of malaria had been obtained from Sumatra, Sulawesi and East Java during December 2011 to December 2013. From 149 sample, 81.9% samples were diagnosed malaria positive by microscopy examination, whereas the PCR results showed that 90.6% of samples were positive. Nested PCR sensitivity is 97.5%, and microscopy 88.2%. Nested PCR specificity is 40.7%, whereas microscopy 78.5%. PPV and NPV for nested PCR are 88,2% and 78.5% respectively, and for microscopy are 97.5% and 40.7% respectively. Nested PCR has a higher sensitivity than microscopy in diagnosing malaria and is able to detect mixed infection better than microscopic examination. However, it is statistically less specific than microscopy examination.

Abstract

Abstract: The existence of human blood in mosquito’s bloodmeal is the characteristic of mosquitoes that bite humans (anthrophophilic). Anthropophilic is one of the indicator to determine the vectorial competence to assess effective and efficient vector. The anthropophilic characteristic was measured by detection of human blood using precipitin test. Benzidine test can be used to detection iron porphyrin through oxidation reaction and catalyzed by hemoglobin as peroxidase enzyme. Heme detection of mosquitoe’s bloodmeal using benzidine in Indonesia has not been reported yet. This study was aimed to obtain the effectiveness of benzidine test to detection human blood in antrophophilic mosquito’s bloodmeal. The mosquitoes were collected using human bait and sweeping collection technique at morning (06:00-09:00), afternoon (15:00-18:00), and in the night (20:00-00:00), and then determine by benzidine test. The results showed that from the collected mosquitoes there were 158 female mosquitoes of Aedes spp and Culex spp. The benzidine test showed 155 female mosquitoes showed discoloration on the indicator and 3 female mosquitoes did not. Conclusion: Benzidine test was effective to detection human blood from the mosquito’s bloodmeal to determine anthrophophilic mosquitoes.Keywords: anthropophilic, bloodmeal, benzidine. Abstrak: Adanya darah manusia dalam pakan darah nyamuk merupakan ciri dari nyamuk yang memiliki kesukaan menggigit hospes manusia (antropofilik). Sifat antropofilik nyamuk adalah salah satu indikator dalam penilaian kompetensi vektorial untuk menilai vektor yang efektif dan efisien. Penilaian sifat antropofilik dilakukan melalui penilaian pakan darah dengan uji presipitasi. Tes benzidine adalah salah satu uji yang dapat dilakukan karena efektif dalam mendeteksi porfirin besi (heme) melalui reaksi oksidasi yang dikatalisis oleh heme sebagai enzim peroksidase. Deteksi porfitin besi pada pakan darah nyamuk menggunakan benzidine belum banyak dilaporkan di Indonesia. Tujuan penelitian ini yaitu untuk mengetahui apakah nyamuk yang mengisap darah hospes manusia (antropofilik) dapat dideteksi dengan uji benzidine. Penelitian dilakukan dengan menangkap nyamuk betina menggunakan umpan manusia dan sweeping pada jam puncak menggigit nyamuk yaitu pagi (06:00-09:00), sore (15:00-18:00), dan malam (20:00-00:00) lalu dilakukan tes benzidine. Hasil: Pada penangkapan nyamuk ditemukan 158 ekor nyamuk betina yang terdiri dari genus Aedes spp dan Culex spp. Pada uji presipitasi ditemukan 155 ekor nyamuk mengalami perubahan warna yang bervariasi pada indikator dan 3 ekor nyamuk tidak berubah warna. Simpulan: uji benzidine dapat dilakukan untuk penilaian sumber pakan darah nyamuk dalam menentukan sifat antropofilik nyamuk. Kata kunci: antropofilik, pakan darah, benzidine.
