Treatment of Kimura disease with intravenous immunoglobulin

Risk of Nephritis and Recurrence in Kimura Disease: A Retrospective Study

Background

Kimura disease (KD) presents a diagnostic challenge to clinicians because of its rarity and atypical symptoms in its early stages, and it is difficult to treat and prone to recurrence or involvement of other organs.

Aims and Objectives

This study aims to investigate the possible relevance of renal involvement and recurrence by analysing the clinical presentations, laboratory results, histopathological features, therapeutic data and follow-up results of KD.

Materials and Methods

A total of 27 patients diagnosed as KD in two hospitals from January 1999 to December 2021 were analysed retrospectively in this study based on the diagnosis of histopathology.

Results

KD mainly affected male more than female (8:1) with the onset age ranging from 3 to 58 years (median 29.8 years). The common initial symptoms included subcutaneous soft tissue or lymph node enlargement, non-specific skin lesions and proteinuria. One patient presented cough and expectoration as the first symptoms. KD patients often had high levels of serum immunoglobulin E (IgE) and basophils, which exhibited a significantly positive correlation with renal involvement and recurrence (p < 0.05). Early mass resection could prevent the development of nephritis and decrease the risk of relapse (p < 0.05).

Conclusion

KD should be noted in patients presenting with intractable and relapsing atopic skin lesions and (or) subcutaneous mass. Patients with high levels of serum IgE and blood basophils may be prone to developing KD-associated nephritis and predict a high risk of recurrence. Early surgical removal of the mass may result in a better prognosis.

Kimura Disease of the Periorbita and Earlobe in a 15-Year-Old Male: A Case Report and Review of the Literature

PURPOSE

The authors describe a case of Kimura disease (KD) affecting the lacrimal gland, the ipsilateral periorbita, and the contralateral earlobe. The authors also review the literature for characteristics and outcomes of KD affecting the periorbita or earlobe.

METHODS

The authors review retrospectively a single chart and abstract data from the English language literature.

RESULTS

A 15-year-old Samoan male presented with a left upper eyelid mass and later the contralateral earlobe and ipsilateral periorbita. Surgical resection was partially effective and normal vision and eye motility were maintained. Histopathology was consistent with KD. Thirty-seven cases of periorbital KD were identified in the literature. The average age of patients with periorbital KD was 31.9 years (standard deviation: 17.8 years), with 81.1% (30/37) of patients being male and 69.4% (25/36) Asian. Over half of periorbital KD patients had lacrimal gland involvement (51.3%; 19/37). Fifteen patients were initially treated with surgery; 3 (20%) had recurrence of the disease. Another 15 patients were initially treated with corticosteroids; 12 (80%) had recurrence of the disease. Ophthalmologic data, when reported, demonstrated that, most patients had no visual (77.8%; 14/18 patients) or motility disturbances (82.4%; 14/17 patients) but most had proptosis 71.4% (10/14). Only 4 cases of earlobe involvement in KD were identified, all in women.

CONCLUSIONS

In the literature, orbital KD was rare but often affected the lacrimal gland and caused proptosis, commonly in young adult Asian males. Vision and extraocular motility were usually normal. Earlobe involvement was very rare. This unique case of KD that affected the orbit and contralateral earlobe corroborates the prior literature that KD is prone to recurrence but may not adversely affect vision or extraocular motility.

Kimura Disease: An Unusual Presentation of Parotid Mass in a Sickle Cell Disease Patient

Kimura disease (KD) is a rare benign chronic inflammatory condition of unknown cause, usually affecting young men of the Asian race. It is frequently associated with nephrotic syndrome. In this report, we present an uncommon case of KD in a 40-year-old Saudi man with sickle cell disease who presented with swelling on the right side of his face. CT scan of the head and neck showed the asymmetrical appearance of both parotid glands: the right side appeared heterogeneously enlarged, with adjacent moderate-to-significant fat stranding. Histologically, hyperplastic changes in lymphoid tissue were observed. The patient underwent superficial parotidectomy and was then followed up till the healing of the surgical site with no complications.

Kimura Disease of the Thigh Treated With Surgical Excision and Dupilumab

ABSTRACT

Kimura disease (KD) is a rare, chronic inflammatory disorder presenting with solitary or multiple masses. Treatment options include surgical excision, corticosteroids, and radiotherapy; however, optimal therapy remains to be established. Moreover, efficacy of a humanized monoclonal antibody, dupilumab (Dupixent), requires to be demonstrated. Here, we present a 36-year-old male patient with an enlarging mass in the left medial thigh and chronic eczema over the abdomen and lower legs. Kimura disease was diagnosed after surgical excision. Postoperative treatment with dupilumab was applied with an initial dose of 600 mg followed by 300 mg every 2 weeks for 8 months. No recurrence of KD was observed in the 1-year follow-up. The eczematous lesions improved greatly. To our knowledge, this is the first report of using dupilumab for treating KD.

Efficacy of add-on therapy with intravenous immunoglobulin in steroid hyporesponsive DRESS syndrome

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare, potentially life-threatening, delayed, drug-induced hypersensitivity reaction. Immediate withdrawal of the culprit drug and administration of systemic corticosteroids is the most widely accepted treatment. However, it is difficult to manage patients with DRESS syndrome who are not responsive to systemic steroids. We studied the efficacy of intravenous immunoglobulins (IVIGs) in patients with DRESS syndrome unresponsive to systemic steroids. We retrospectively reviewed patients with DRESS syndrome who received IVIG in addition to systemic steroids during 2012-2017 and compared the clinical features and course of DRESS syndrome, before and after IVIG treatment. Eighteen DRESS patients (9 men) were included. The most frequent offending drugs were dapsone in five patients, followed by vancomycin in three patients, and carbamazepine in three patients. Rash, fever, lymphadenopathy, atypical lymphocytes, and hepatic involvement were common clinical findings. IVIG treatment was added within a median time of 7 days from the commencement of systemic steroid therapy. After IVIG treatment (total dosage: 1-2 g/kg), the fever resolved within a median time of 1 day (range, 0-3) and liver enzymes improved substantially within a median time of 13 days (range, 0-27). No severe adverse reactions related to IVIG therapy were observed in this study; however, there was one case of mortality. The addition of IVIG in DRESS syndrome in cases refractory to systemic steroid treatment may be helpful in hastening recovery. However, comparative studies using a placebo group are needed.

Eosinophilic chronic rhinosinusitis and concurrent Kimura's disease treated with mepolizumab

Kimura's disease is a rare, benign, chronic inflammatory disorder characterised by its eosinophilic infiltrate. Patients often present with one or more progressively enlarging subcutaneous lymph nodes in the head and neck region or enlarging salivary glands. We describe the case of a 26-year-old man presenting with severe peripheral eosinophilia and upper airway inflammatory symptoms, who later developed cervical lymphadenopathy and formally diagnosed with Kimura's disease. Based on our English-language MEDLINE literature search, to our knowledge this is the first case report describing treatment of Kimura's disease with mepolizumab.

Kimura's disease: effects of age on clinical presentation

BACKGROUND

Kimura's disease (KD) is known to be dominant among young Asian men, but it can also occur in middle- and advanced-aged people. The clinical characteristics of KD, especially by age, are not well known.

AIM

This study was performed to investigate the effects of age on the clinical characteristics of KD.

DESIGN

We conducted a case series study.

METHODS

All case studies of patients diagnosed with KD were collected via a PubMed search of studies published until August 2018. The data were analyzed by age group.

RESULTS

In total, 215 studies were reviewed (238 patients; mean age of 36 years). The male:female ratio was 4:1 overall, 17:1 in patients aged <20 years, 4:1 in patients aged 20-39 years and 2:1 in patients aged ≥40 years (P = 0.01). The percentage of patients with pruritus was 15.4% overall, 3.8% in patients aged <20 years, 15.5% in patients aged 20-39 years and 21.7% in patients aged ≥40 years (P = 0.02). The time to diagnosis was 5.3 years overall, 3.2 years in patients aged <20 years, 4.7 years in patients aged 20-39 years and 7.1 years in patients aged ≥40 years (P < 0.01).

CONCLUSIONS

The proportion of female patients affected the incidence of pruritus, and the time to diagnosis increased as the patients' age increased. There were no significant age-related differences in region/race, complications, multiplicity, laterality, anatomical distribution, maximum size, eosinophil count, immunoglobulin E level, initial treatment, recurrence or outcomes. This may be useful information for the diagnosis of KD.

Kimura disease: No age or ethnicity limit

Kimura disease is a chronic inflammatory disease that mainly manifests as a lump in the cervical region. Although the underlying pathophysiology is not clear yet, the diagnosis can be established based on specific histopathological characteristics. The first case of this disease was described in China, as well as the majority of subsequent cases that were also described in the Far East countries made Kimura disease traditionally a disease of adult patients of Asian descent. This report describes the occurrence of Kimura disease in pediatric non-Asian patient with a similar clinicopathologic presentation.

Comparison of the efficacy of different treatment modalities for Kimura's disease

The objective of this study was to investigate the clinical features of Kimura's disease in the head and neck region and to compare the local recurrence rate between three therapies used for the treatment of this disease. The clinicopathological information of 46 hospitalized patients suffering from Kimura's disease in the head and neck region over a 10-year period was reviewed retrospectively. All lesions were clinically observed in the head and neck region. These 46 patients underwent a total of 58 treatments; nine patients underwent multiple treatments due to local recurrence. Of the 58 treatments, 32 involved surgical excision alone, 24 involved surgical excision and postoperative low-dose radiotherapy (20-40Gy), one was a combination of ultrasound-guided core needle biopsy and radiotherapy, and one was a combination of incisional biopsy and subsequent radiotherapy. During the follow-up period, nine patients suffered 16 local recurrences. The recurrence rate of surgical excision combined with low-dose radiotherapy was much lower than that of surgical excision alone or radiotherapy alone (both P<0.05). It is concluded that Kimura's disease is a benign condition with a good prognosis, and surgical excision combined with postoperative low-dose radiotherapy is associated with the lowest local recurrence rate in the treatment of this disease.

Comparison of Local Recurrence Rate of Three Treatment Modalities for Kimura Disease

Eosinophilic hyperplastic lymphogranuloma, also known as Kimura disease, is a benign and chronic inflammatory condition, predominantly involving the head and neck region. Surgical excision, radiotherapy (RA), surgical resection combined with low-dose postoperative radiotherapy and oral corticosteroids are 4 treatment modalities reported to control this disease effectively. Local recurrence, however, is common and the optimum treatment for Kimura disease is controversial. Thus, the present meta-analysis was performed to identify the treatment modality associated with the lowest local recurrence. Electronic databases (Cochrane Library, Wiley Online Library, PubMed, Chinese National Knowledge Infrastructure, and Wanfang Data) were searched. Data were also obtained from other sources such as related references and communication with the relevant authors. Two reviewers screened the literature according to preselected criteria. All studies involving different treatments for Kimura disease were collected. After data extraction and research quality assessment, the meta-analysis of 22 studies involving 570 patients was conducted using STATA 12.1 software. Meta-analysis revealed that administration of RA or surgical excision alone were inferior in controlling local recurrence compared with surgical resection combined with postoperative RA (risk ratio (RR) = 2.72; 95% confidence interval (CI), 1.47-5.04 and RR = 4.72; 95% CI, 2.53-8.82). Surgical excision alone did not show significant advantage in controlling local recurrence compared with RA alone (RR = 2.13; 95% CI, 0.88-5.17). Surgical resection combined with postoperative RA is superior to either surgery or RA alone in treating Kimura disease. More large scale prospective randomized controlled trials, however, should be conducted to assess the long-term effects and safety issues.

Pulmonary embolism as the initial clinical presentation of Kimura disease: case report and literature review

Pulmonary embolism is clinically critical in that if misdiagnosed or delayed, the mortality is very high. The recognition of its risk factor or underlying disease is important for prevention of recurrence. Kimura disease is a rare, chronic inflammatory disease, which is seldom associated with thrombosis. We reported a 47-year-old male case presenting with pleural pain and dyspnoea and was found to have pulmonary embolism. After successful management of pulmonary embolism, he was noticed to have eosinophilia and lymphadenopathy. Pathologic examination of a resected lymph node has confirmed the diagnosis of Kimura disease. The patient was treated with corticosteroid and cyclosporine A, with a significant improvement of the symptoms and signs of Kimura disease and no recurrence of any thromboembolism. Associated literatures were reviewed to explore the pathogenesis underlying the thrombotic event in Kimura disease cases. It is suggested that hypereosinophilia may play a key role in thrombosis formation. The control of hypereosinophilia may contribute to the prevention of thrombosis and its recurrence in patients with Kimura disease.

Kimura's disease involving the peripheral nerve of the arm in a child: a case report

A 7-year-old Korean boy was referred for a nontender mass in the left arm. He had a 5-year history of a poorly defined painless mass on the medial side of the left elbow. The ultrasonogram of the left arm indicated an ill-defined, lobulating solid mass involving the deep soft tissue layer. The fat-suppressed T2-weighted magnetic resonance image showed a poorly marginated, homogeneous high-signal intensity mass. On further follow-up of 1 year and 6 months, the mass showed no change in size and nature. At surgery, a poorly demarcated inflammatory mass was dissected from a branch of the superficial radial nerve and excised completely. There was no recurrence and any dysfunction, except temporary localized hypoesthesia of the medial aspect of the left arm at the 3.6-year follow-up.
