Shaiful Ehsan SM, Iskandar FO, Mohd Ashraf AR

Med J Malaysia, 2019 08;74(4):347-348.
PMID: 31424049

Varicella zoster infection is one of the self-limiting viral infections during childhood and dengue fever is an endemic infection in Malaysia, which commonly occurs in the form of nonspecific febrile illness at the initial stage. It is rare for the two viral infections to occur simultaneously. A case of dengue fever without warning sign in a five-year old girl was reported, with early symptoms of fever and vesicular rashes. She was clinically diagnosed with varicella zoster infection during the first visit. Surprisingly, she remained febrile even on day six of illness despite no new vesicular lesions on her skin. Due to suspicion of another infection, follow-up investigation was done and revealed isolated thrombocytopenia. This finding was confirmed with positive NS1Ag. A case of rare dengue fever concomitant with varicella zoster infection was reported.

Coronavirus Disease 2019 (COVID-19) is an acute respiratory infectious disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection that started in Wuhan, China in December 2019 and has spread rapidly worldwide. It's critical to take extra precautions if a person has chronic illnesses (comorbidities), such as human immunodeficiency (HIV) infection. Concerns about people living with HIV (PLHIV) having a higher risk of serious COVID-19 disease may be based on the assumption that PLHIV are more likely to be immunocompromised. On the other hand, limited information is available in such people about the characteristics of co-infection between SARS-CoV-2 and Human Immunodeficiency Virus (HIV) who are at greater risk than the general population. Our findings, is of a 32 year old patient who came to Emergency Unit of Wangaya Hospital, Medical Faculty, Udayana University in Denpasar, Bali with complaint of fever, dry cough, and shortness of breath since prior 3 days and had also the past history prolonged fever, weight loss more than 10% 4 weeks. Diagnosis of COVID-19 was confirmed by nasopharyngeal swab sample was used for RT-PCR assay and PITC to confirm HIV infection. He had prolonged hospitalized and discharge after 18 days.

Fulltext Molecular detection of leptospirosis and melioidosis co-infection: A case report

Mohd Ali MR, Mohamad Safiee AW, Thangarajah P, Fauzi MH, Muhd Besari A, Ismail N, et al.

J Infect Public Health, 2017 Nov-Dec;10(6):894-896.

Leptospirosis and melioidosis are important tropical infections caused by Leptospira and Burkholdheria pseudomallei, respectively. As both infections share similar clinical manifestations yet require different managements, complementary laboratory tests are crucial for the diagnosis. We describe a case of Leptospira and B. pseudomallei co-infection in a diabetic 40-year-old woman with history of visit to a freshwater camping site in northern Malaysia. To our knowledge, this is the first case of such double-infection, simultaneously demonstrated by molecular approach. This case highlights the possibility of leptospirosis and melioidosis co-infections and their underlying challenges in the rapid and accurate detection of the etiologic microorganism.

2020 will be marked in history for the dreadful implications of the COVID-19 pandemic that shook the world globally. The pandemic has reshaped the normality of life and affected mankind in the aspects of mental and physical health, financial, economy, growth, and development. The focus shift to COVID-19 has indirectly impacted an existing air-borne disease, Tuberculosis. In addition to the decrease in TB diagnosis, the emergence of the TB/COVID-19 syndemic and its serious implications (possible reactivation of latent TB post-COVID-19, aggravation of an existing active TB condition, or escalation of the severity of a COVID-19 during TB-COVID-19 coinfection), serve as primary reasons to equally prioritize TB. On a different note, the valuable lessons learnt for the COVID-19 pandemic provide useful knowledge for enhancing TB diagnostics and therapeutics. In this review, the crucial need to focus on TB amid the COVID-19 pandemic has been discussed. Besides, a general comparison between COVID-19 and TB in the aspects of pathogenesis, diagnostics, symptoms, and treatment options with importance given to antibody therapy were presented. Lastly, the lessons learnt from the COVID-19 pandemic and how it is applicable to enhance the antibody-based immunotherapy for TB have been presented.

Fulltext Clinical predictors of dengue fever co-infected with leptospirosis among patients admitted for dengue fever - a pilot study

Suppiah J, Chan SY, Ng MW, Khaw YS, Ching SM, Mat-Nor LA, et al.

J Biomed Sci, 2017 Jun 28;24(1):40.
PMID: 28659189 DOI: 10.1186/s12929-017-0344-x

BACKGROUND: Dengue and leptospirosis infections are currently two major endemics in Malaysia. Owing to the overlapping clinical symptoms between both the diseases, frequent misdiagnosis and confusion of treatment occurs. As a solution, the present work initiated a pilot study to investigate the incidence related to co-infection of leptospirosis among dengue patients. This enables the identification of more parameters to predict the occurrence of co-infection.
METHOD: Two hundred sixty eight serum specimens collected from patients that were diagnosed for dengue fever were confirmed for dengue virus serotyping by real-time polymerase chain reaction. Clinical, laboratory and demographic data were extracted from the hospital database to identify patients with confirmed leptospirosis infection among the dengue patients. Thus, frequency of co-infection was calculated and association of the dataset with dengue-leptospirosis co-infection was statistically determined.
RESULTS: The frequency of dengue co-infection with leptospirosis was 4.1%. Male has higher preponderance of developing the co-infection and end result of shock as clinical symptom is more likely present among co-infected cases. It is also noteworthy that, DENV 1 is the common dengue serotype among all cases identified as dengue-leptospirosis co-infection in this study.
CONCLUSION: The increasing incidence of leptospirosis among dengue infected patients has posed the need to precisely identify the presence of co-infection for the betterment of treatment without mistakenly ruling out either one of them. Thus, anticipating the possible clinical symptoms and laboratory results of dengue-leptospirosis co-infection is essential.

Fulltext The dangers of accepting a single diagnosis: case report of concurrent Plasmodium knowlesi malaria and dengue infection

Chong SE, Mohamad Zaini RH, Suraiya S, Lee KT, Lim JA

Malar J, 2017 01 03;16(1):2.
PMID: 28049485 DOI: 10.1186/s12936-016-1666-y

BACKGROUND: Dengue and malaria are two common, mosquito-borne infections, which may lead to mortality if not managed properly. Concurrent infections of dengue and malaria are rare due to the different habitats of its vectors and activities of different carrier mosquitoes. The first case reported was in 2005. Since then, several concurrent infections have been reported between the dengue virus (DENV) and the malaria protozoans, Plasmodium falciparum and Plasmodium vivax. Symptoms of each infection may be masked by a simultaneous second infection, resulting in late treatment and severe complications. Plasmodium knowlesi is also a common cause of malaria in Malaysia with one of the highest rates of mortality. This report is one of the earliest in literature of concomitant infection between DENV and P. knowlesi in which a delay in diagnosis had placed a patient in a life-threatening situation.
CASE PRESENTATION: A 59-year old man staying near the Belum-Temengor rainforest at the Malaysia-Thailand border was admitted with fever for 6 days, with respiratory distress. His non-structural protein 1 antigen and Anti-DENV Immunoglobulin M tests were positive. He was treated for severe dengue with compensated shock. Treating the dengue had so distracted the clinicians that a blood film for the malaria parasite was not done. Despite aggressive supportive treatment in the intensive care unit (ICU), the patient had unresolved acidosis as well as multi-organ failure involving respiratory, renal, liver, and haematological systems. It was due to the presentation of shivering in the ICU, that a blood film was done on the second day that revealed the presence of P. knowlesi with a parasite count of 520,000/μL. The patient was subsequently treated with artesunate-doxycycline and made a good recovery after nine days in ICU.
CONCLUSIONS: This case contributes to the body of literature on co-infection between DENV and P. knowlesi and highlights the clinical consequences, which can be severe. Awareness should be raised among health-care workers on the possibility of dengue-malaria co-infection in this region. Further research is required to determine the real incidence and risk of co-infection in order to improve the management of acute febrile illness.

Fulltext A Fatal Case of Candida auris and Candida tropicalis Candidemia in Neutropenic Patient

Mohd Tap R, Lim TC, Kamarudin NA, Ginsapu SJ, Abd Razak MF, Ahmad N, et al.

Mycopathologia, 2018 Jun;183(3):559-564.
PMID: 29383574 DOI: 10.1007/s11046-018-0244-y

We report a fatal case of Candida auris that was involved in mixed candidemia with Candida tropicalis, isolated from the blood of a neutropenic patient. Identification of both isolates was confirmed by amplification and sequencing of internal transcribed spacer and D1/D2 domain of large subunit in rRNA gene. Antifungal susceptibility test by E-test method revealed that C. auris was resistant to amphotericin B, anidulafungin, caspofungin, fluconazole, itraconazole and voriconazole. On the other hand, C. tropicalis was sensitive to all antifungal tested. The use of chromogenic agar as isolation media is vital in detecting mixed candidemia.
