RESUMO
Integrase inhibitor is uniquely available as single tablet regimen (STR) in Korea. In this study, the durability until 96 weeks was compared between dolutegravir/abacavir/lamivudine (D/A/L) and elvitegravir/cobicistat/tenofovir/emtricitabine (E/T/E) in treatment naïve human immunodeficiency virus 1 (HIV-1) infected individuals. From 2014 to 2017, 153 and 234 subjects started D/A/L and E/T/E, respectively. During 96 weeks, 73 discontinued initial STR and the reason of discontinuation was typable in 44. The frequency of drug adverse event related discontinuation (AEDC) was higher in D/A/L (13.1% vs. 6.4%, P = 0.023) while most non-AE related discontinuations occurred in E/T/E (8/9), such as drug-drug interaction, meal requirement and virologic failure. AEDC occurred usually within 24 weeks (20/35) and D/A/L to E/T/E AEDC incidence rate ratio was 3.71 (95% confidence interval, 1.36–10.10) in this period. Regarding the durability, D/A/L and E/T/E revealed no significant difference at week 96 (P = 0.138) while durability of D/A/L was worse in the aspect of AEDC (P = 0.013).
RESUMO
Patients with systemic rheumatic diseases (SRD) are vulnerable for coronavirus disease (COVID-19). The Korean College of Rheumatology recognized the urgent need to develop recommendations for rheumatologists and other physicians to manage patients with SRD during the COVID-19 pandemic. The working group was organized and was responsible for selecting key health questions, searching and reviewing the available literature, and formulating statements. The appropriateness of the statements was evaluated by voting panels using the modified Delphi method. Four general principles and thirteen individual recommendations were finalized through expert consensus based on the available evidence. The recommendations included preventive measures against COVID-19, medicinal treatment for stable or active SRD patients without COVID-19, medicinal treatment for SRD patients with COVID-19, and patient evaluation and monitoring. Medicinal treatments were categorized according to the status with respect to both COVID-19 and SRD. These recommendations should serve as a reference for individualized treatment for patients with SRD. As new evidence is emerging, an immediate update will be required.
RESUMO
Background@#Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected pneumonia emerged in Wuhan, China in December 2019. In this retrospective multicenter study, we investigated the clinical course and outcomes of novel coronavirus disease 2019 (COVID-19) from early cases in Republic of Korea. @*Methods@#All of the cases confirmed by real time polymerase chain reaction were enrolled from the 1st to the 28th patient nationwide. Clinical data were collected and analyzed for changes in clinical severity including laboratory, radiological, and virologic dynamics during the progression of illness. @*Results@#The median age was 40 years (range, 20–73 years) and 15 (53.6%) patients were male. The most common symptoms were cough (28.6%) and sore throat (28.6%), followed by fever (25.0%). Diarrhea was not common (10.7%). Two patients had no symptoms. Initial chest X-ray (CXR) showed infiltration in 46.4% of the patients, but computed tomography scan confirmed pneumonia in 88.9% (16/18) of the patients. Six patients (21.4%) required supplemental oxygen therapy, but no one needed mechanical ventilation. Lymphopenia was more common in severe cases. Higher level of C-reactive protein and worsening of chest radiographic score was observed during the 5–7 day period after symptom onset. Viral shedding was high from day 1 of illness, especially from the upper respiratory tract (URT). @*Conclusion@#The prodromal symptoms of COVID-19 were mild and most patients did not have limitations of daily activity. Viral shedding from URT was high from the prodromal phase. Radiological pneumonia was common from the early days of illness, but it was frequently not evident in simple CXR. These findings could be plausible explanations for the easy and rapid spread of SARS-CoV-2 in the community.
RESUMO
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 not yet has established its treatment, but convalescent plasma has been expected to increase survival rates as in the case with other emerging viral infections. We describe two cases of COVID-19 treated with convalescent plasma infusion. Both patients presented severe pneumonia with acute respiratory distress syndrome and showed a favorable outcome after the use of convalescent plasma in addition to systemic corticosteroid. To our knowledge, this is the first report of the use of convalescent plasma therapy for COVID-19 in Korea.
RESUMO
As of February 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak started in China in December 2019 has been spreading in many countries in the world. With the numbers of confirmed cases are increasing, information on the epidemiologic investigation and clinical manifestation have been accumulated. However, data on viral load kinetics in confirmed cases are lacking. Here, we present the viral load kinetics of the first two confirmed patients with mild to moderate illnesses in Korea in whom distinct viral load kinetics are shown. This report suggests that viral load kinetics of SARS-CoV-2 may be different from that of previously reported other coronavirus infections such as SARS-CoV.

The first human immunodeficiency virus (HIV) infection was reported in Korea in 1985. The number of HIV-infected persons domestically increased in the 1990s showing epidemic indigenousization. Since then, the number of new infections gradually increased every year, and recently more than 1,000 newly infected cases were reported per year. A total of 12,522 infected individuals have been reported up to 2015, of which 2,020 died. The male to female ratio was 15.4:1, and 34.2% of them were under 30 years old. The infection route was homosexual and bisexual contact in 60.1% of cases and heterosexual contact in 34.6% of cases. Candidiasis, Pneumocystis pneumonia, tuberculosis were common as a AIDS (acquired immune deficiency syndrome)-defining illness. But with the introduction of antiretroviral therapy in the late 1990s, non-AIDS defining illnesses such as metabolic complications, cardiovascular diseases, bone diseases, and neuropsychiatric disorders such as neurocognitive dysfunction, depression, and anxiety are emerging as new health problems. The management policy switched its focus from regulating and monitoring of HIV-infected persons to ensuring access to treatment and promotion of voluntary HIV testing in high-risk groups. Also as the age of the infected persons increases, a need for various supports such as social rehabilitation, life counseling, and welfare has emerged.

RESUMO
Mixed-species malaria infections are often unrecognized or underestimated. We hereby report the first described case of mixed infection with Plasmodium falciparum and Plasmodium ovale malaria in a returned traveller in Korea. In August 2016, a 25-year-old returned traveller from Cameroon and Democratic Republic of Congo presented with fever. He was diagnosed as P. falciparum malaria and successfully treated with artesunate. And 5 weeks after the completion of treatment, he presented with fever and diagnosed as P. ovale infection. P. ovale infection is a rare cause of malaria and often shows delayed presentation due to its dormant liver stage as hypnozoites. At re-presentation, the immunochromatographic test and microscopic examinations of our patient did not reveal P. ovale, which was only detected via polymerase chain reaction (PCR) assay. This case highlights the importance of considering malaria infection even in persons who have previously received malaria treatment. It also shows the usefulness of PCR testing for diagnosing P. ovale infections, which often present with a low level of parasitaemia.

The present study investigated prevalence of integrase strand transfer inhibitors (INSTI) resistance mutations in HIV-1-infected antiretroviral therapy (ART)-naïve patients in Korea. From 106 plasma samples, amplification and sequencing of integrase genes was performed, and major or minor mutations were calculated by the Stanford HIV drug resistance mutation interpretation algorithm. No major INSTI resistance mutations were found, and 14 minor mutations were detected in 13 (12.3%) patients. The present data support the recommendation that routine testing for INSTI resistance mutations before starting ART is not necessary.

This nationwide, prospective cohort study evaluated pulmonary function and radiological sequelae according to infection severity in 73 survivors from the 2015 Middle East respiratory syndrome (MERS) outbreak in Korea. Patients with severe pneumonia in MERS-coronavirus infection had more impaired pulmonary function than those with no or mild pneumonia at the 1-year follow-up, which was compatible with the radiological sequelae. Severe pneumonia significantly impairs pulmonary function and makes long radiological sequelae in MERS.

During the evolution of human immunodeficiency virus (HIV), transmissions between humans and primates resulted in multiple HIV lineages in humans. This evolution has been rapid, giving rise to a complex classification and allowing for worldwide spread and intermixing of subtypes, which has consequently led to dozens of circulating recombinant forms. In the Republic of Korea, 12,522 cases of HIV infection have been reported between 1985, when AIDS was first identified, and 2015. This review focuses on the evolution of HIV infection worldwide and the molecular epidemiologic characteristics of HIV in Korea.

BACKGROUND: Travel-related risks for infectious diseases vary depending on travel patterns such as purpose, destination, and duration. In this study, we describe the patterns of travel and prescription of vaccines as well as malaria prophylaxis medication (MPM) at a travel clinic in South Korea to identify the gaps to fill for the optimization of pre-travel consultation. MATERIALS AND METHODS: A cohort of travel clinic visitors in 2011 was constructed and early one-third of the visitors of each month were reviewed. During the study period, 10,009 visited the travel clinic and a retrospective chart review was performed for 3,332 cases for analysis of travel patterns and prescriptions. RESULTS: People receiving yellow fever vaccine (YFV) (n = 2,933) were traveling more frequently for business and tourism and less frequently for providing non-medical service or research/education compared to the 399 people who did not receive the YFV. Overall, most people were traveling to Eastern Africa, South America, and Western Africa, while South-Eastern Asia was the most common destination for the non-YFV group. Besides YFV, the typhoid vaccine was the most commonly prescribed (54.2%), while hepatitis A presented the highest coverage (74.7%) considering the natural immunity, prior and current vaccination history. Additionally, 402 (82.5%) individuals received a prescription for MPM among the 487 individuals travelling to areas with high-risk of malaria infection. Age over 55 was independently associated with receiving MPM prescription, while purpose of providing service and travel duration over 10 days were associated with no MPM prescription, despite travelling to high-risk areas. CONCLUSION: Eastern Africa and South America were common travel destinations among the visitors to a travel clinic for YFV, and most of them were travelling for tourism and business. For the individuals who are traveling to areas with high-risk for malaria, more proactive approach might be required in case of younger age travelers, longer duration, and travel purpose of providing service to minimize the risk of malaria infection.

The average life expectancy of human immunodeficiency virus (HIV)-infected patients has improved dramatically following the advent of highly active anti-retroviral therapy. However, this increased life expectancy has led to a greater incidence of non-acquired immune deficiency syndrome related diseases, including cardiovascular diseases and other malignancies. Increased bone fragility is also a significant concern, with the incidence of osteoporosis and osteoporotic fractures 3- and 2-times more likely, respectively, among HIV-infected patients. Bone mineral density screenings for osteoporosis will therefore become more important as the HIV-infected population ages. Here, we describe six cases of osteoporotic fractures in HIV-infected patients in Korea.

Patients with human immunodeficiency virus (HIV) infection have a higher burden of seizures, but few studies have examined seizures in HIV-infected individuals in Korea. A retrospective study was conducted to determine the epidemiology and clinical characteristics of seizures in patients with HIV infection. Among a total of 1,141 patients, 34 (3%) had seizures or epilepsy; 4 of these individuals had epilepsy before HIV infection, and the others showed new-onset seizures. Most patients exhibited moderate (200 to 500, n = 13) or low (below 200, n = 16) CD4 counts. The most common seizure etiology was progressive multifocal leukoencephalopathy (n = 14), followed by other HIV-associated central nervous system (CNS) complications (n = 6). Imaging studies revealed brain lesions in 21 patients. A total of 9 patients experienced only one seizure during the follow-up period, and 25 patients experienced multiple seizures or status epilepticus (n = 2). Multiple seizures were more common in patients with brain etiologies (P = 0.019) or epileptiform discharges on EEG (P = 0.032). Most seizures were controlled without anticonvulsants (n = 12) or with a single anticonvulsant (n = 12). Among patients with HIV infection, seizures are significantly more prevalent than in the general population. Most seizures, with the exception of status epilepticus, have a benign clinical course and few complications.

BACKGROUND: Rabies is an acute fatal viral disease generally transmitted from infected animals to humans through bites. It is distributed worldwide. The number of Korean people traveling to rabies-endemic countries and being bitten by infected animals has been increasing recently. Therefore, we investigated international travelers who received rabies post-exposure prophylaxis (PEP) at the National Medical Center (NMC) and compared the data with those of other clinics. MATERIALS AND METHODS: This study was a retrospective review of 106 patients who visited the International Travel Clinic of the NMC and received rabies PEP between July 2006 and December 2012. During that period, we used the Essen intramuscular regimen protocol. Complete rabies PEP was defined as 5 doses of rabies vaccination with or without rabies immunoglobulin (RIG) administration according to the World Health Organization guidelines. RESULTS: A total 106 cases documented within the period of 6 years were selected, including 10 children younger than 15 years and 96 older than 15 years. The mean age of the patients who received PEP was 33.4 years. Of the patients, 53 were male and another 53 were female. Most of the exposures occurred in Southeast Asia, predominantly from dog bites (71, 66.9%). The lower extremities were the most frequent site of exposure (37, 34.9%). All the patients began receiving rabies vaccination for prophylaxis after exposure, and 51 received rabies vaccination with RIG. Meanwhile, 74 cases (69.8%) initiated rabies vaccination overseas, but only 10 of them received RIG while overseas; the remaining 32 (30.2%) initiated rabies vaccination after returning to Korea. Within 7 days, all the children and 74 adults received their first rabies vaccination. Six adults initiated first rabies vaccination after 1 week. Eleven of the 106 patients stopped PEP before 5 doses, among whom 4 (1 child and 3 adults) discontinued vaccination after confirming that the biting animal remained healthy throughout 10 days of observation. None of the patients had been previously vaccinated against rabies. CONCLUSIONS: Most of the overseas travelers who visited our clinic after being bitten by suspected rabid animals received appropriate rabies PEP. However, the interval between exposure and first rabies vaccination was often delayed. Tourists who plan to travel in rabies enzootic regions need to be aware that prompt initiation of PEP is important to reduce the risk for developing human rabies.

We hereby observe four co-infection cases of pandemic influenza H1N1 and Mycobacterium tuberculosis with various clinical presentations. It may be prudent to consider M. tuberculosis co-infections when patients with pandemic influenza reveal unusual clinical features that do not improve despite appropriate treatments against the influenza, especially in Korea, in the endemic areas of M. tuberculosis.
