Chikungunya outbreak in Bangladesh (2017): sociodemographic and clinical characteristics of patients from three hotspots

Background Chikungunya is a severely debilitating disease. Bangladesh witnessed one of the largest outbreaks in 2017. Here, we described the clinical profile of the chikungunya outbreak in Bangladesh and its heterogeneity across three hotspots. Methods This was a descriptive cross-sectional study of 432 individuals interviewed from the outpatient department of three study sites (Dhaka, Chittagong, and Sitakundu Upazilla of Bangladesh) after confirmation by the study physicians. Both laboratory-confirmed cases and probable cases were recruited between July and October 2017. Results Of all, 18% (79) were laboratory confirmed, and 353 82% (335) were probable cases. The male:female ratio was almost equal (1.09:1), and the predominant age group was 18–59 years. The mean age of the presentation was 36.07 ± 13.62 (SD) years. Fever and arthralgia were the most common presentations and were present in > 95% of cases. Other frequent symptoms were fatigue, myalgia, headache, nausea, and vomiting. Approximately half of the patients had arthritis and erythematous rash. Arthritis was predominant in Chittagong city, while maculopapular rash was not observed in Sitakunda city. However, fatigue, nausea, and vomiting are more common among patients in Dhaka city. Significant heterogeneity of clinical manifestations was present across the three hotspots (p < 0.05 for all). Both confirmed and probable cases shared similar characteristics except muscle ache (p = 0.22) and rash (p = 0.37). Conclusion The clinical profile of chikungunya virus-induced disease displays significant location-related heterogeneity in Bangladesh during a large outbreak. Although the causes of such differences are unclear, improved public and medical personnel education on this condition may lead to earlier diagnosis and treatment.

Atypical skin manifestation in severe acute chikungunya infection in a pregnant woman: a case report

Introduction Patients with chikungunya virus infection commonly present with fever, skin rash, and severe joint pain. The vesiculobullous rash is rare in adults but common in infants. In addition, septic shock and acute respiratory distress syndrome are rare complications of atypical and severe acute chikungunya infection. Case presentation We report the presence of an 18-year-old Thai female, at 31 weeks gestation, with fever, maculopapular rash, and polyarthritis. The rash later progressed to a vesiculobullous pattern, and she developed septic shock and acute respiratory distress syndrome. Skin biopsy and blood were positive for chikungunya virus RNA. The patient was intubated with a mechanical ventilator and subsequently fully recovered. Conclusion Atypical skin manifestation and severe acute disease is likely due to immune response attenuation in pregnancy. The possibility of progression to severe or atypical disease in pregnant women suffering chikungunya should always be considered.

Ecthyma gangrenosum in a patient with febrile pancytopenia

Ecthyma gangrenosum (EG) is a cutaneous infection most commonly associated with Pseudomonas bacteremia and usually occurring in immunocompromised patients [1]. The infection progresses sequentially from a maculopapular rash to hemorrhagic bullae, then to necrotic ulcerations with surrounding erythema [2]. Herein, we report a case of ecthyma gangrenosum in an immunologically compromised patient. A 65-year-old female was admitted to the oncohematology department for febrile pancytopenia. Blood work revealed severe thrombocytopenia at 15,000/mm³), an absolute neutrophil count of 180 cells/mm³, and anemia. A sternal bone marrow puncture found 15% of plasma cells. Four days after the admission, the patient had a painful, quickly extending lesion on the abdomen. She described erythema that progressed to pustules, then ulcerations. On general clinical evaluation, the patient was feverish at 40°C. A dermatological examination revealed the presence of a 6 cm purpuric patch on the left flank with a central necrotic eschar (Fig. 1). The diagnosis of ecthyma gangrenosum was reached and the patient was treated with ceftazidime and vancomycin. Unfortunately, having gone into septic shock, the patient died one week later.

A case report of Aceclofenac induced Drug induced Hypersensitivity syndrome

<p>Drug-induced hypersensitivity syndrome (DIHS) is an unusual, potentially life-threatening, multi-organ adverse drug reaction. DIHS usually develops 2-6 weeks after drug initiation. We report a case of 21 years old female with maculopapular rash associated with fever and generalised lymphadenopathy, 15 days after intake of aceclofenac. Treatment with intravenous corticosteroids, antibiotics and fluids along with cessation of the offending drug resulted in successful resolution.</p>

Case Report: Vasculitis Triggered by SIRT in a Patient With Previously Untreated Cholangiocarcinoma

Arising from the biliary tract, cholangiocarcinoma is a rare and aggressive epithelial cancer. According to the primary site, it can be further classified into intrahepatic, perihilar and distal types. Due to the lack of symptoms early in the disease course, most patients are diagnosed at advanced stages. Being not candidates for curative surgical management, these patients are treated with palliative systemic chemotherapy, and their prognosis remains poor. Using radioisotopes like yttrium-90 -labeled microspheres (90Y), radioembolization represents a local approach to treat primary and secondary liver tumors. In the case of intrahepatic cholangiocarcinoma, radioembolization can be used as a primary treatment, as an adjunct to chemotherapy or after failing chemotherapy. An 88-year-old man underwent radioembolization for a previously untreated stage II intrahepatic cholangiocarcinoma. One week later, he presented to our clinic with a non-pruritic maculopapular rash of the lower extremities and abdomen, worsening fatigue and low-grade fever. Laboratory exams, including hepatitis screening, were within normal limits. Showing positive immunofluorescence staining for immunoglobulin M (IgM) and complement 3 (C3) in vessel walls without IgA involvement, the skin biopsy results were compatible with leukocytoclastic vasculitis. Apart from the anticancer intervention, there have been no recent medication changes which could explain this complication. Notably, we did not observe any side effects during or after the perfusion scan with technetium-99m macroaggregated albumin (MAA) performed prior to radioembolization. The symptoms resolved quickly after a short course of colchicine and did not reappear at cholangiocarcinoma progression. In the absence of other evident causes, we conclude that the onset of leukocytoclastic vasculitis in our patient was directly linked to the administration of yttrium-90 -labeled microspheres. Our report therefore demonstrates that this condition can be a rare but manageable complication of 90Y liver radioembolization.

Ring-shaped erythema and herpetic infections in children

Exanthema in children accompanies various diseases. Often, polymorphic elements on the skin occur against the background of infectious diseases. Until the second part of the XXth century, children’s classical infectology described only 6 diseases in children characterized by spotty and maculopapular rash. Now there are more than two dozen exanthemes in children with an “infectious origin”. The article considers 2 clinical cases of a relatively rare annular erythema in patients of 1 year 2 months and 11 months associated with chronic herpetic infections. The article presents photo documents of the dynamics of the skin process and laboratory parameters against the background of antiviral therapy.

Symmetrical Drug-related Intertriginous and Flexural Exanthema (Baboon Syndrome)

Baboon syndrome, also called symmetrical drug-related intertriginous and flexural exanthema (SDRIFE), is an erythematous maculopapular rash that presents in skin folds in a symmetrical pattern. This condition may develop after the patient starts a particular agent. Treatment consists of stopping the associated trigger and medicating with topical or systemic corticosteroids. A 30-year-old man with odynophagia, otalgia and fever was prescribed amoxicillin. He developed erythematous and pruriginous lesions in the cubital fossa and inguinal regions. He attended the emergency department (ED) where he was prescribed penicillin. Lesions continued to progressively worsen with a bilateral symmetrical pattern in the axillary region and later in the nape folds, popliteal regions, and on the perineum and buttocks. The patient presented to the ED for a second time, where he was diagnosed with baboon syndrome and prescribed topical steroids with clear improvement.

Serum sickness reaction to obinutuzumab in a patient with chronic lymphocytic leukaemia

Serum sickness (SS) is a known phenomenon; however, it is commonly missed due to vague symptoms, and is usually confounded by other aetiologies that present similarly. Obinutuzumab is a novel anti-CD20 antibody agent that has been approved for chronic lymphocytic leukaemia (CLL) treatment. At the time of approval, it was not linked to SS; however, this phenomenon has been recognised with other anti-CD20 agents like rituximab. SS remains a rare entity, but it is important to be recognised accurately and quickly in the appropriate circumstances, so that effective treatment with corticosteroids can be initiated to alleviate inflammatory symptoms. Here we present a patient with CLL who developed maculopapular rash, fever and polyarthritis and elevated inflammatory markers consistent with serum sickness triggered by obinutuzumab and was effectively treated with corticosteroids.

ML-10 Tirabrutinib, a second-generation BTK inhibitor in relapsed and refractory primary CNS lymphoma: A single institute study

BACKGROUND: The prognosis of relapsed and refractory (r/r) primary CNS lymphoma (PCNSL) is poor, and the development of new therapeutic agents is desirable. Comprehensive genetic analysis of PCNSL has shown that MYD88 and CD79B are frequently mutated and are oncogenic drivers, suggesting that Bruton’s tyrosine kinase (BTK), which is located downstream of MYD88 and CD79B, may be a reasonable therapeutic target. Tirabrutinib is a second-generation oral BTK inhibitor recently approved in Japan for the treatment of r/r PCNSL. In this study, we evaluated the efficacy and safety of tiraburtinib treatment of r/r PCNSL at Saitama Medical University. MATERIAL AND METHODS: Eighteen patients with r/r PCNSL to HD-MTX-based regimens were treated with 480 mg tiraburtinib daily under fasting conditions until disease progression. RESULTS: The median age was 63.5 years, and the median KPS was 70. Nine patients (50%) achieved a CR, 2 (11%) had a partial response, 3 (17%) had stable disease, and 4 (22%) had progressive disease. After a median follow-up of 17.3 months, the median progression-free survival was 7.9 months, and the median overall survival was 23.6 months. There were four cases of long-term treatment lasting more than one year. Grade 3 or higher adverse events were observed in 1 case of maculopapular rash, 1 case of cardiac failure, 1 case of neutropenia, and 1 case of lymphopenia. CONCLUSION: Tiraburtinib can be administered relatively safely to patients with relapsed or refractory PCNSL, and a certain degree of efficacy can be expected. Which patients can be treated with tiraburtinib over the long term, when can stop tirabrutinib treatment for patients with long-term CR, and the mechanism of tiraburtinib resistance needs to be determined.

Kounis syndrome secondary to nimesulide ingestion: a case report

Background Kounis syndrome, also known as "allergic myocardial infarction," is a rare co-occurrence of acute coronary syndrome (ACS) in the setting of hypersensitivity reaction to any agent. Non-steroidal anti-inflammatory drugs (NSAIDs) like are often implicated in causing allergic reactions. Here, we present a case of anterior wall myocardial infarction (AWMI) occurred following angioedema secondary to intake of Nimesulide, not described earlier in literature. Case presentation A 45-year-old female developed generalized pruritic, erythematous maculopapular rash, facial puffiness, oral ulcers and hoarseness of voice within few hours following consumption of Nimesulide for fever and body-ache. Due to development of hypotension, electrocardiogram (ECG) was done, which revealed ST elevation in V2–V6, with marked elevation of troponin (TnI) and creatine kinase (CK-MB). He had no chest pain or shortness of breath. Echocardiography showed regional wall motion (RWMA) abnormality in left anterior descending artery (LAD) territory with an ejection fraction of 25%. Coronary angiography showed a complete thrombotic cutoff of LAD, for which Tirofiban infusion was started to decrease thrombus burden. Repeat angiography on next day showed 80% lesion in proximal LAD for which she underwent revascularization with a drug-eluting stent. The patient later showed improvement in cardiac function at 8 months of follow-up. Conclusions The occurrence of ACS requiring percutaneous coronary intervention (PCI) in the setting of allergic reactions is rarely reported in the literature. One should be aware of the rare possibility of Kounis syndrome in the setting of hypersensitivity reaction when accompanying features of symptoms suggestive of coronary artery disease co-exists. When indicated, ECG monitoring and cardiac biomarkers in patients with allergic responses help to identify this rare and treatable condition.
