Drug rash with eosinophilia and systemic symptoms to anti-tuberculosis therapy: A retrospective review of inpatients at an academic medical centre in the United States

This retrospective cohort study analyzes the presentation, diagnosis, and treatment outcomes of patients who developed drug rash with eosinophilia and systemic symptoms (DRESS) to tuberculosis (TB) therapy in a TB non-endemic region. Anti-TB agents represented 7.5% of all antimicrobial-induced DRESS cases, and rifampin was the most commonly implicated agent among drugs used to treat TB.

A pruritic pedunculated pink nodule on the leg

Herein, we present a patient with a lipidized fibrous histiocytoma, an underrecognized variant of dermatofibroma (cutaneous fibrous histiocytoma). Our patient presented with a nodule on the ankle that showed foamy histiocytes and hyalinized collagen bundles on histology. This case highlights a classic presentation and features of lipidized fibrous histiocytoma, raising further awareness of this distinctive variant of dermatofibroma that should be distinguished from xanthoma and xanthogranuloma.

Characteristics of patients with juvenile dermatomyositis from 2001-2021 at a tertiary care center

BACKGROUND

Juvenile dermatomyositis (JDM) is the most common inflammatory myopathy in the pediatric population and can represent a medical emergency. However, many features of JDM remain poorly understood, disease presentation is highly variable, and predictors of disease course have yet to be identified.

METHODS

This retrospective chart review included 47 JDM patients seen at a tertiary care center over a 20-year period. Characteristics such as demographics, clinical signs and symptoms, antibody positivity, dermatopathology features, and treatments were recorded.

RESULTS

All patients had evidence of cutaneous involvement, whereas 88.4% experienced muscle weakness. Constitutional symptoms and dysphagia were commonly present. The most frequent cutaneous findings were Gottron papules, heliotrope rash, and nailfold changes. Anti-TIF1? was the most prevalent myositis-specific autoantibody. Management involved systemic corticosteroids in nearly all cases. Strikingly, the dermatology department was only involved in the care of four in every ten (19/47) patients.

CONCLUSIONS

Prompt recognition of the strikingly reproducible skin findings present in JDM can improve disease outcomes in this population. This study highlights the need for increased education of such pathognomonic findings as well as more multidisciplinary care. In particular, a dermatologist should be involved in the care of patients presenting with muscle weakness and skin changes.

Wells Syndrome-Like Histologic Pattern Caused by a Permanent Tattoo

ABSTRACT

Tattoo reactions have become more common as tattoos gain visibility and popularity worldwide. A variety of inflammatory patterns have been described in association with tattoos- more commonly fibrosing, granulomatous, lichenoid, pseudolymphomatous, and spongiotic patterns. To date, there has been one case report of a Wells syndrome-like inflammatory pattern associated with a temporary Henna tattoo. Here we present the first case of a permanent tattoo with resulting flame figures, histologically resembling Wells syndrome. We believe this uncommon histologic pattern might be of interest for pathologists to be aware of.

ABVD and BEACOPP regimens' effects on fertility in young males with Hodgkin lymphoma

Purpose

Considering the increased cancer patient survivorship, the focus is now on addressing the impacts of treatment on quality of life. In young people, altered reproductive function is a major issue and its effects in young males are largely neglected by novel research. To improve clinician awareness, we systematically reviewed side effects of chemotherapy for Hodgkin lymphoma (HL) in young males.

Methods

The review was prospectively registered (PROSPERO N. CRD42019122868). Three databases (Medline via PUBMED, SCOPUS, and Cochrane Library) were searched for studies featuring males aged 13-51-years who underwent chemotherapy for HL using ABVD (Adriamycin® (doxorubicin), bleomycin, vinblastine, and dacarbazine) or BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) regimens. These chemotherapy regimens were compared against each other using sperm characteristics, FSH, and inhibin B levels to measure fertility levels.

Results

Data were extracted from five studies featuring 1344 patients. 6 months post-ABVD saw marked deterioration in sperm count, further reduced by more cycles (P = 0.05). Patients treated with BEACOPP rather than ABVD were more prone to oligospermia. Receiving fewer cycles of both regimens increased the likelihood of sperm production recovering. Patients treated with 6-8 cycles of BEACOPP did not recover spermiogenesis.

Conclusions

ABVD and BEACOPP regimens significantly reduce fertility function to varying effects depending on treatment duration. ABVD temporarily causes significant reductions in male fertility, whereas BEACOPP’s effects are more permanent. Therefore, clinicians should discuss fertility preservation with male patients receiving infertility-inducing gonadotoxic therapy. Further high-quality studies are required to more adequality describe the risk to fertility by chemotherapy.

SCT for severe autoimmune diseases: consensus guidelines of the European Society for Blood and Marrow Transplantation for immune monitoring and biobanking

Over the past 15 years, SCT has emerged as a promising treatment option for patients with severe autoimmune diseases (ADs). Mechanistic studies recently provided the proof-of-concept that restoration of immunological tolerance can be achieved by haematopoietic SCT in chronic autoimmunity through eradication of the pathologic, immunologic memory and profound reconfiguration of the immune system, that is, immune ‘resetting'. Nevertheless, a number of areas remain unresolved and warrant further investigation to refine our understanding of the underlying mechanisms of action and to optimize clinical SCT protocols. Due to the low number of patients transplanted in each centre, it is essential to adequately collect and analyse biological samples in a larger cohort of patients under standardized conditions. The European society for blood and marrow transplantation Autoimmune Diseases and Immunobiology Working Parties have, therefore, undertaken a joint initiative to develop and implement guidelines for ‘good laboratory practice' in relation to procurement, processing, storage and analysis of biological specimens for immune reconstitution studies in AD patients before, during and after SCT. The aim of this document is to provide practical recommendations for biobanking of samples and laboratory immune monitoring in patients with ADs undergoing SCT, both for routine supportive care purposes and investigational studies.

Autologous stem cell transplantation in severe treatment-resistant Crohn's disease: long-term follow-up of UK patients treated on compassionate basis

BACKGROUND

Although autologous stem cell transplantation (ASCT) may achieve disease control in severe treatment-resistant Crohn's disease (CD), relapse is frequent, and there is little information regarding long-term outcomes in terms of response to subsequent treatments and complications of ASCT.

DESIGN

Retrospective evaluation of UK patients treated on a compassionate basis from three UK tertiary centres.

METHODS

We summarize long-term outcomes of six previously unreported patients with severe treatment-resistant CD treated with ASCT according to international guidelines between 2003 and 2009. Median duration of CD before ASCT was 14 (7-22) years. Following stem cell mobilization, patients were treated with high-dose cyclophosphamide (200 mg/kg) and rabbit anti-thymocyte globulin (7.5 mg/kg) followed by ASCT.

RESULTS

All patients tolerated ASCT with routine toxicities and no treatment-related mortality and are alive at 50-123 months post-ASCT. Clinical and endoscopic remissions of CD were confirmed at 3 months post-ASCT in five patients, although median time to next treatment for inflammatory disease was 10 months (range: 3-16 months). Subsequently, disease control was achieved with previously ineffective and newer treatments, with surgery performed predominantly for pre-existing fibrotic strictures. Two patients became independent of home total parenteral nutrition (TPN). Reported late complications of ASCT included hypothyroidism and ovarian failure.

CONCLUSION

Long-term follow-up supports the safety and feasibility of ASCT as a means of achieving short-term control of severe CD whilst potentially re-sensitizing the disease to medical therapy and reducing requirements for surgery and TPN. Given the inevitability of relapse, pre-emptive salvage and/or maintenance treatments post-ASCT should be the focus of future trials.

Second autologous transplant with cyclosporin/interferon α-induced graft versus host disease for patients who have failed first-line consolidation

The prognosis for patients with non-Hodgkin's lymphoma (NHL) and advanced Hodgkin's disease (HD) who relapse following autologous transplant is poor. We report on a pilot study designed to evaluate the feasibility of using Cyclosporin A and interferon alpha to induce autologous GVHD following a second autologous transplant for relapsed lymphoma. In all, 10 patients entered the study with median age 46.5 years. Diagnosis was NHL (n=7) or Hodgkin's lymphoma (n=3). All had relapsed from a prior autologous transplant. The second transplant was well tolerated by all patients. Histological changes consistent with cutaneous GVHD developed in 30% of patients at a median of 22.5 days from transplant and settled spontaneously in all cases. Five patients have died (four from progressive disease) at a median 7 months from second transplant. Five patients are still alive and in complete remission at a median of 20 months from transplant. Median overall survival for the group is 13.5 months and median relapse-free survival has not been reached at 42 months. This is a well-tolerated regimen for use in this poor-risk group of patients with lymphoma. The overall survival and event-free survival are encouraging, however further studies are necessary.

The use of intravenous intermediate dose melphalan and dexamethasone as induction treatment in the management of de novo multiple myeloma

The variable absorption of melphalan from the gastrointestinal tract results in response rates between 40 and 60%. High dose melphalan increases response rates but at the cost of increased morbidity and mortality. We have investigated intravenous intermediate dose melphalan and dexamethasone in the treatment of patients presenting with de novo multiple myeloma with the object of reducing toxicity while preserving an improved response rate compared to oral melphalan and prednisolone. The results show that this treatment can be delivered safely on an outpatient basis in patients up to the age of 78 yr; 82% of patients achieved an objective response and 30% a complete haematological and clinical remission. Median overall survival for the whole group is 37 months.
