Views: 371HTML: 36 PDF: 270Background: This report presents the influence of immunosuppression by new rheumatological therapies on hepatitis E virus infection in a 54-year-old male patient with an anti-synthetase syndrome and treatment with methotrexate and rituximab.
Case description: The patient arrived at the Emergency Department with epigastric pain, vomiting and dark urine. Initial examination revealed signs of inflammation and hepatic dysfunction. Subsequent laboratory tests and imaging confirmed acute hepatitis E infection in the context of recent initiation of rituximab therapy. Despite initial suspicion of pancreatitis, subsequent investigations ruled out pancreatic involvement. Treatment with ribavirin, along with supportive measures, led to significant clinical improvement with resolution of jaundice, ascites, and oedema.
Conclusions: This case underscores the importance of considering hepatitis E in patients with autoimmune conditions, especially when initiating immunosuppressive therapies, a situation that is not well described in scientific literature and is increasingly common, necessitating proper recognition. -
Views: 273HTML: 14 PDF: 226Castleman’s disease (CD) and thrombotic thrombocytopenic purpura (TTP) are rare diseases that can affect the general population, especially those with HIV. Owing to their rarity, the association between CD and TTP remains insufficiently understood. In this study, we present a case of a 53-year-old patient with controlled HIV infection who presented with fever, lymphadenopathy, severe anaemia, and thrombocytopenia. After a series of tests, the diagnosis was concurrent human herpesvirus 8 (HHV8)-related multicentric CD (MCD) and TTP. Only four male patients were previously reported having this association, with HHV8 present in four and HIV in three patients, suggesting that coinfection with HHV8 and HIV is a pivotal factor in MCD with TTP occurrence.

Views: 531HTML: 52 PDF: 324Infection caused by Candida auris has rapidly become a global health threat. C. auris created a significant healthcare burden due to various complicating factors, including misidentification by commercial identification methods, potent antifungal resistance, high mortality rates and the possibility of nosocomial outbreaks through direct contact. In Vietnam, there are currently no clinical reports on C. auris infections. Here, we present four clinical cases of C. auris infections in the Department of Pulmonary Medicine of Cho Ray Hospital in southern Vietnam. Through this report, we aim to highlight the attention to the emergence of C. auris in Vietnam. Further research on C. auris infections is warranted, focusing on newly observed clinical characteristics present in all cases in this report, including hypoalbuminaemia and corticosteroid usage. Moreover, one case of resistance to amphotericin B has been identified, possibly due to prior exposure to this antifungal agent.

Views: 453HTML: 65 PDF: 370Background: Primary bone lymphoma (PBL) is a rare form of extra nodal non-Hodgkin’s lymphoma (NHL).
Case description: We describe a 39-year-old-male with no medical history who presented with unilateral facial swelling following a tooth extraction. Initial diagnoses after various presentations over the course of three weeks, based on inflammatory and infectious aetiologies. However, the patient was ultimately diagnosed with diffuse large B-cell lymphoma.
Discussion: Symptoms of PBL are very similar to inflammatory and infectious diseases of the bone, such as osteomyelitis or osteonecrosis. Clinical features of PBL involving the head and neck include persistent jaw pain, tooth mobility secondary to extensive destruction of bone, and in advanced cases, lip numbness and swelling. On examination it may present as an exposed necrotic bone with surrounding soft tissue oedema. Misdiagnosis of these lesions as an infectious or inflammatory aetiology may lead to an unnecessary delay in lymphoma treatment, and subsequently worsen the prognosis if caught at a later stage. Therefore, any concerning lesion, especially in the oral cavity, must be subjected to early histopathological evaluation to differentiate PBL from osteomyelitis and/or osteonecrosis.
Conclusion: This case report highlights the importance of an early histopathological evaluation to prevent delay in the diagnosis of primary bone lymphomas. -
Views: 459HTML: 54 PDF: 273Tuberculosis (TB) is primarily a respiratory infection with huge mortality and morbidity worldwide. Extrapulmonary TB infection is common, affecting lymph nodes, pleura, and abdomen, but the primary biliary presentation without lung involvement is exceedingly rare. We report on a 38-year-old male patient who presented with isolated obstructive jaundice secondary to TB infection. This case highlights the importance of considering TB infection in the differential diagnosis of obstructive jaundice, especially in the endemic area. We also provide a literature review on TB infection, mainly in the biliary tract.

Views: 428HTML: 52 PDF: 288Background: Rhodococcus equi is a Gram-positive microorganism that causes infections, particularly in immunocompromised patients. Treatment duration can be prolonged. While vancomycin is an effective drug in this scenario, its use may lead to renal damage. Studies have shown that continuous vancomycin infusion appears to be a safe strategy in terms of adverse effects compared to bolus administration.
Case description: We present the case of a 71-year-old female liver transplant recipient. After being diagnosed with a mediastinal infection caused by Rhodococcus equi with poor response to initial therapy, she required 12 months of continuous intravenous domiciliary infusion of vancomycin combined with oral levofloxacin and rifampicin. There was no drug-related complication throughout the follow-up.
Conclusions: The use of continuous vancomycin infusion has emerged as a safer, more efficient, and cost-effective alternative to intermittent administration. We want to emphasise the uniqueness of this case, where despite the unprecedented treatment duration, no adverse effects occurred. -
Views: 448HTML: 65 PDF: 351Introduction: Neurosyphilis (NS) refers to a central nervous system infection caused by Treponema pallidum. In recent years, there has been an increasing incidence of syphilis; however, NS is uncommon compared to the era before the discovery of penicillin. Manifestations are usually non-specific, ranging from asymptomatic cases to syphilitic meningitis, meningovascular syphilis, general paresis and tabes dorsalis. Meningovascular syphilis can cause an inflammatory arteritis of cerebral arteries, leading to vascular occlusion and cerebral infarction.
Case description: We report a case of an ischaemic stroke in a patient with several vascular risk factors, presenting with right hemiparesis, hemihypesthesia and dysarthria. Initial computed tomography with angiography of the head and neck was normal; however, magnetic resonance imaging of the brain revealed a thalamic and internal capsule infarct. Serum T. pallidum antibodies were positive, as well as a rapid plasma reagin test. Cerebrospinal fluid analysis confirmed the diagnosis of neurosyphilis, and the patient was treated with ceftriaxone for 14 days due to a penicillin allergy.
Discussion and conclusion: Although there is a high prevalence of stroke in patients with NS, this condition is typically underdiagnosed. Untreated NS carries a higher risk of stroke recurrence compared to other risk factors. Therefore, early diagnosis and treatment are essential. This case highlights the importance of considering NS in stroke victims, even in older patients with several additional vascular risk factors, to prevent recurrence and other complications. -
Views: 365HTML: 114 PDF: 308Cytomegalovirus (CMV) infection is often asymptomatic. However, in certain individuals, it can cause non-specific signs and symptoms that maybe hard to recognise. The condition may therefore be overlooked or misdiagnosed, leading to prolonged illness and serious sequelae. In this case report, we present a rare instance of CMV infection in an HIV-negative patient who had a remote history of splenectomy and was experiencing prolonged fever and markedly elevated white blood cell (WBC) count.

Views: 397HTML: 60 PDF: 288Onychomycosis (OM), a widespread fungus that affects the toenails and/or fingernails, causes a large amount of morbidity and is very frequent in the general population. The best treatment is systemic antifungals. Terbinafine is a potent antifungal drug that works by targeting the keratin and lipids found in fungi. In the United States, the prevalence of this nail ailment ranges from 2% to 14%; it is 5.5% globally. Here, we describe a case of aplastic anaemia linked to oral terbinafine use. Clinicians should be aware of this rare adverse effect and early discontinuation of the treatment is required to prevent significant morbidity and mortality.

Views: 463HTML: 42 PDF: 300Corynebacterium spp. are Gram-positive bacteria, and recent studies have proposed a potential link between granulomatous mastitis and Corynebacterium kroppenstedtii infections, posing a challenge in selecting appropriate antibiotics, particularly in pregnant women. A young pregnant woman presented with a palpable lump in her left breast. Subsequent assessment revealed the presence of necrotising granulomatous mastitis attributed to C. kroppenstedtii. Initially treated with amoxicillin/clavulanate, the patient showed no improvement. Consequently, clindamycin was administered based on culture and sensitivity results, which resulted in a favourable response with no recurrence of symptoms. This report aims to emphasise the efficacy of clindamycin as a treatment option for granulomatous mastitis caused by C. kroppenstedtii.
