RESUMEN
Progressive multifocal leukoencephalopathy (PML) rarely occurs in patients with systemic lupus erythematosus (SLE). This report presents the case of a patient who developed PML due to SLE-associated multiple factors. A 60-year-old woman diagnosed with SLE undergoing multiple immunosuppressive therapies, including azathioprine, presented with cerebral cortical symptoms, lymphocytopenia, and vitamin B12 deficiency and was subsequently diagnosed with SLE-associated PML. We evaluated the cause and disease activity of PML, focusing on the longitudinal assessment of lymphocytopenia, JC virus (JCV) DNA copy number in the cerebrospinal fluid, and magnetic resonance imaging (MRI) findings. Discontinuing azathioprine and initiating alternative immunosuppressive treatments with intramuscular vitamin B12 injections affected lymphocytopenia and disease management. However, despite recovery from lymphopenia and JCV DNA copy number being low, the large hyperintense and punctate lesions observed on the fluid-attenuated inversion recovery (FLAIR) images exhibited varying behaviors, indicating that the balance between contributing factors for PML may have fluctuated after the initial treatment. Clinicians should be meticulous when assessing the underlying pathology of the multifactorial causes of PML due to SLE. The difference in the transition pattern of these lesions on FLAIR images may be one of the characteristics of MRI findings in PML associated with SLE, reflecting fluctuations in disease activity and the progression stage of PML.
RESUMEN
BACKGROUND: The aim of this study was to assess the impact of immunosuppression management on coronavirus disease 2019 (COVID-19) outcomes. METHODS: We performed a single-center retrospective study in a cohort of 358 lung transplant recipients (LTx) over the period from March 2020 to April 2022. All included symptomatic patients had at least one positive SARS-CoV-2 rt-PCR. We used a composite primary outcome for COVID-19 including increased need for oxygen since the hospital admission, ICU transfer, and in-hospital mortality. We assessed by univariate and multivariate analyses the risk factors for poor outcomes. RESULTS: Overall, we included 91 LTx who contracted COVID-19. The COVID-19 in-hospital mortality rate reached 4.4%. By hierarchical clustering, we found a strong and independent association between the composite poor outcome and the discontinuation of at least one immunosuppressive molecule among tacrolimus, cyclosporine, mycophenolate mofetil, and everolimus. Obesity (OR = 16, 95%CI (1.96; 167), p = 0.01) and chronic renal failure (OR = 4.6, 95%CI (1.4; 18), p = 0.01) were also independently associated with the composite poor outcome. Conversely, full vaccination was protective (OR = 0.23, 95%CI (0.046; 0.89), p = 0.047). CONCLUSION: The administration of immunosuppressive drugs such as tacrolimus, cyclocporine or everolimus can have a protective effect in LTx with COVID-19, probably related to their intrinsic antiviral capacity.

BACKGROUND: Children usually have an asymptomatic or mild course of SARS-CoV-2 infection, studies in immunocompromised patients have shown a different evolution. The aim of this study was to describe the clinical, laboratory, and radiologic manifestations of pediatric solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) patients testing positive for SARS-CoV-2. METHODS: A multicenter retrospective, observational descriptive study was conducted in 3 tertiary hospitals in Madrid (Spain) between March 2020 and December 2022. Consecutive patients aged 0-18 attending the corresponding pediatric emergency departments with a positive result in the real-time polymerase chain reaction test or antigenic test to detect SARS-CoV-2 in the nasopharyngeal sample were included. RESULTS: A total of 31 children were included in the study. Sixteen (51.6%) were patients with HSCT and 15 (48.3) were patients with SOT. The median time from transplantation to COVID-19 was 1.2 years (IQR:0.5-5.1). The SOT cohort included liver (n = 4, 12.9%), kidney (n = 4, 12.9%), heart (n = 3, 9.7%), multivisceral (n = 3, 9.7%), and lung (n = 1, 3.2%). Of the 31 patients, only one was asymptomatic. The most common symptom on presentation was fever (76.7%). Abnormalities were seen on chest X-ray in 8 (66.6%) of the 12 patients. There was no significant difference in clinical manifestations, lymphopenia and radiological findings regardless of the type of transplantation or immunosuppression status. Thirteen patients (41.9%) were hospitalized. There were no patient deaths. CONCLUSIONS: In our study, we found that the clinical course and outcome of SOT and HSCT pediatric patients with COVID-19 were generally favorable.

BACKGROUND: Pneumocystis jirovecii pneumonia (PJP) is a common and troublesome complication of kidney transplantation. In the era of prophylaxis, the peak incidence of PJP after kidney transplantation and specific characteristics of late-onset PJP have always been debated. METHODS: We performed a retrospective study by analysing the data of post-transplantation pneumonia in adult kidney transplantation recipients between March 2014 and December 2021 in The Affiliated First Hospital of University of Science and Technology of China (USTC). A total of 361 patients were included and divided into early-onset PJP, late-onset PJP and non-PJP groups. The characteristics of each group and related risk factors for the late-onset patients were investigated. RESULTS: Some patients developed PJP 9 months later with a second higher occurrence between month 10 and 15 after transplantation. Compared with non-PJP, ABO-incompatible and cytomegalovirus (CMV) viremia were significantly associated with late onset of PJP in multivariate analysis. The use of tacrolimus, CMV viremia, elevated CD8(+) T cell percent and hypoalbuminemia were risk factors for late PJP. Receiver operating characteristic curve analysis demonstrated that a combination of those factors could increase the sensitivity of prediction remarkably, with an area under the curve of 0.82, a sensitivity of 80% and a specificity of 83%. CONCLUSIONS: PJP could occur months after kidney transplantation. ABO-incompatible transplant recipients are at high risk of PJP. In the later stages of transplantation, CMV viremia, T lymphocyte subsets percentage and serum albumin levels should be monitored in patients using tacrolimus.

Dermatologic complications are common following allogeneic hematopoietic stem cell transplantation, but dermatologic complications among pediatric patients undergoing hematopoietic stem cell transplantation for the treatment of sickle cell disease have been poorly characterized. In this case series of 17 patients (<21 years old) with sickle cell disease who underwent hematopoietic stem cell transplantation, 16 (94.1%) experienced one or more dermatologic complications after transplant, with the most common complications including acute or chronic mucocutaneous graft-versus-host disease (GVHD) (34.1% of complications), skin eruptions of unknown origin (15.9% of complications), infections (15.9% of complications), and chemotherapy-related pigmentary changes (11.4% of complications). Patients who developed acute or chronic skin GVHD were significantly older at the time of hematopoietic stem cell transplantation. These findings highlight the need to closely monitor for dermatologic complications in pediatric patients who undergo hematopoietic stem cell transplantation for sickle cell disease and underscore the importance of involving dermatology early on when skin complications occur, although further research with a larger multicenter study could help clarify the risk for dermatologic complications and help identify potential ways to mitigate this risk.

BACKGROUND: Over one-third of multiple sclerosis (MS) patients are post-menopausal women, the primary demographic affected by breast cancer. After breast cancer diagnosis, there is little information about patients' clinical experiences with both diseases. OBJECTIVE: Utilize a case series of MS patients diagnosed with breast cancer to characterize oncologic and MS trajectories, and generate novel insights about clinical considerations using qualitative analysis. METHODS: A single-center retrospective review was performed on medical record data of patients with MS and breast cancer. Thematic analysis was used to characterize experiences with the concurrent diagnoses. RESULTS: For the 43 patients identified, mean age was 56.7 years at cancer diagnosis and MS duration was 16.5 years. Approximately half were treated with MS disease modifying therapy at cancer diagnosis, and half of these subsequently discontinued or changed therapy. Altogether 14% experienced MS relapse(s) during follow-up (with 2 relapses in the first 2 years), with mean annualized relapse rate of 0.03. Cohort Expanded Disability Status Scale (EDSS) scores remained stable during follow-up. Qualitative insights unique to this population were identified regarding immunosuppression use and neurologic symptoms. CONCLUSIONS: MS relapses were infrequent, and there was modest progression during breast cancer treatment. Oncologic outcomes were comparable to non-MS patients with similarly staged cancer.

INTRODUCTION: Noroviral infection can lead to chronic diarrhea in solid organ transplant (SOT) recipients with significant morbidity and mortality. Existing literature has described a wide spectrum of illness and has not come to a consensus on the optimal management of this condition. METHODS: We undertook a retrospective review of all adult SOT recipients between 1/1/2018 and 12/31/2020 who were diagnosed with their first episode of noroviral diarrhea (NVD). Demographic, clinical interventions, and outcomes within 6 months of diagnosis were recorded. Patients' outcomes were classified as either resolved, improved or persistent at 6 months. RESULTS: Seventy-nine SOT recipients were included. Thirty-eight patients (48%) had chronic diarrhea at baseline (CDB). Thirty-two patients (40%) received nitazoxanide, 28 patients (35%) had their immunosuppression adjusted and seven patients (9%) received intravenous immunoglobulin. Diarrhea improved or resolved in 68 patients (85%). Improvement or resolution of diarrhea was observed in 98% of those who did not have history of chronic diarrhea versus 74% in those who did (p = .002). NVD improved in all 12 patients who had mycophenolate discontinued, although this was not statistically significant (p = .131). CONCLUSION: CDB was associated with worse outcomes regardless of intervention. A low threshold to test for NVD in SOT recipients with chronic diarrhea is prudent to prevent delayed diagnosis.

BACKGROUND: The role of protocol liver biopsies (PLB) in the follow-up of pediatric liver transplant recipients remains questionable. This single-center retrospective study aimed to evaluate their clinical impact on the long-term management of pediatric liver transplant recipients. METHODS: We described histopathological lesions and clinical consequences for patient management of PLB performed 1, 5, 10, 15, 20, and 25 years after pediatric liver transplantation (LT). RESULTS: A total of 351 PLB performed on 133 patients between 1992 and 2021 were reviewed. PLB found signs of rejection in 21.7% of cases (76/351), and moderate to severe fibrosis in 26.5% of cases (93/351). Overall, 264 PLB (75.2%) did not cause any changes to patient care. Immunosuppression was enhanced after 63 PLB, including 23 cases of occult rejection. The 1-year PLB triggered significantly more changes, while biopsies at 15, 20, and 25 years produced the lowest rates of subsequent modifications. PLB had a significantly higher probability of inducing therapeutic changes if the patient had abnormal biological or imaging results (odds ratio [OR] 2.82 and 2.06), or a recent history of rejection or bacterial infection (OR 2.22 and 2.03). CONCLUSION: Our results suggest that, although it often does not prompt any treatment changes, PLB could be performed because of its ability to detect silent rejection requiring an increase in immunosuppression. PLB could be carried out 1, 5, and 10 years after LT and then every 10 years in patients with normal biological and imaging results and no recent complications, while other patients could be kept on a 5-year protocol.

BACKGROUND: The organ most commonly invaded in echinococcosis is the liver; the lungs, brain, kidneys, heart, and spleen are rarely invaded, and multi-organ involvement in echinococcosis is even rarer. No studies have reported renal invasion after liver transplantation for hepatic alveolar echinococcosis. CASE PRESENTATION: We report here a case of renal invasion 2 years after allogeneic liver transplantation in a 53-year-old female patient with hepatic alveolar echinococcosis combined with lung metastases. At the time of the first consultation, the lesion had been found to involve the second hepatic hilum combined with lung metastases, but the patient requested conservative treatment, and the lesion was not controlled by taking albendazole for 3 years. After discussion in the treatment group, it was decided to use allogeneic liver transplantation and lung segmental resection for surgical treatment, after which the patient was put on long-term oral immunosuppression. She was hospitalized 2 years later for low back pain and diagnosed with renal alveolar echinococcosis. Due to significant compression and left-sided renal insufficiency, the final option was to remove the diseased kidney. It is worth mentioning that signs of unexplained urinary tract infection were present throughout the course of treatment. CONCLUSION: This study suggests that extra attention should be paid to the presence of cryptogenic lesions in patients with hepatic alveolar echinococcosis who already have definite metastatic lesions. Immunosuppressive drugs after liver transplantation in patients with hepatic echinococcosis may cause occult lesions to develop into active ones. In clinical practice, particular attention should be paid to patients with hepatic alveolar echinococcosis with long-term concomitant signs of unexplained urinary tract infections, which may be a precursor clinical feature of cryptogenic renal alveolar echinococcosis.

BACKGROUND: Except in a few retrospective studies mainly including patients under chemotherapy, information regarding the impact of immunosuppressive therapy on the prognosis of patients admitted to the intensive care unit (ICU) for septic shock is scarce. Accordingly, the PACIFIC study aimed to asses if immunosuppressive therapy is associated with an increased mortality in patients admitted to the ICU for septic shock. METHODS: This was a retrospective epidemiological multicentre study. Eight high enroller centres in septic shock randomised controlled trials (RCTs) participated in the study. Patients in the "exposed" group were selected from the screen failure logs of seven recent RCTs and excluded because of immunosuppressive treatment. The "non-exposed" patients were those included in the placebo arm of the same RCTs. A multivariate logistic regression model was used to estimate the risk of death. RESULTS: Among the 433 patients enrolled, 103 were included in the "exposed" group and 330 in the "non-exposed" group. Reason for immunosuppressive therapy included organ transplantation (n = 45 [44%]) or systemic disease (n = 58 [56%]). ICU mortality rate was 24% in the "exposed" group and 25% in the "non-exposed" group (p = 0.9). Neither in univariate nor in multivariate analysis immunosuppressive therapy was associated with a higher ICU mortality (OR: 0.95; [95% CI 0.56-1.58]: p = 0.86 and 1.13 [95% CI 0.61-2.05]: p = 0.69, respectively) or 3-month mortality (OR: 1.13; [95% CI 0.69-1.82]: p = 0.62 and OR: 1.36 [95% CI 0.78-2.37]: p = 0.28, respectively). CONCLUSIONS: In this study, long-term immunosuppressive therapy excluding chemotherapy was not associated with significantly higher or lower ICU and 3-month mortality in patients admitted to the ICU for septic shock.

Therapy of myasthenia gravis (MG) is increasingly oriented to the patient's antibody status. In addition to symptomatic therapy, steroids, classic long-term immunosuppressive therapies and thymectomy are regularly used. In recent years, new therapeutic approaches have been developed that particularly benefit acetylcholine receptor (AChR) antibody (Abs) positive patients with highly active disease. While the C5 complement inhibitor eculizumab was reserved for treatment-refractory generalized courses of AChR-Abs positive MG, two new drugs, the neonatal Fc receptor inhibitor efgartigimod and the more advanced C5 complement inhibitor ravulizumab, have recently been approved as add-on therapy for AChR-Abs positive generalized MG (gMG). In highly active courses of MG with Abs against the muscle-specific receptor tyrosine kinase (MuSK), the use of rituximab should be considered early in the course of the disease. The efficacy of the new drugs in children and adolescents with juvenile MG (JMG) is currently being tested in clinical trials. The new guideline recommends the use of modern immunomodulators based on a step-by-step approach depending on disease activity. With the German Myasthenia Register (MyaReg), the changing therapeutic landscape and quality of life of patients with myasthenic syndromes can be assessed, thus providing real-world data on the care of MG patients. Despite treatment based on the previous guideline, many MG patients suffer considerable impairment to their quality of life. With the new immunomodulators, there is the possibility of early intensified immunotherapy, which, in contrast to long-term immunosuppressants, can lead to a rapid improvement in the course of the disease.

(1) Introduction: Liver transplantation represents the gold-standard therapy in eligible patients with acute liver failure or end-stage liver disease. The COVID-19 pandemic dramatically affected the transplantation landscape by reducing patients' addressability to specialized healthcare facilities. Since evidence-based acceptance guidelines for non-lung solid organ transplantation from SARS-CoV-2 positive donors are lacking, and the risk of bloodstream-related transmission of the disease is debatable, liver transplantation from SARS-CoV-2 positive donors could be lifesaving, even if long-term interactions are unpredictable. The aim of this case report is to highlight the relevance of performing liver transplantation from SARS-CoV-2 positive donors to negative recipients by emphasizing the perioperative care and short-term outcome. (2) Case presentation: A 20-year-old female patient underwent orthotropic liver transplantation for Child-Pugh C liver cirrhosis secondary to overlap syndrome, from a SARS-CoV-2 positive brain death donor. The patient was not infected nor vaccinated against SARS-CoV-2, and the titer of neutralizing antibodies against the spike protein was negative. The liver transplantation was performed with no significant complications. As immunosuppression therapy, the patient received 20 mg basiliximab (Novartis Farmacéutica S.A., Barcelona, Spain) and 500 mg methylprednisolone (Pfizer Manufacturing Belgium N.V, Puurs, Belgium) intraoperatively. Considering the risk of non-aerogene-related SARS-CoV-2 reactivation syndrome, the patient received remdesivir 200 mg (Gilead Sciences Ireland UC, Carrigtohill County Cork, Ireland) in the neo-hepatic stage, which was continued with 100 mg/day for 5 days. The postoperative immunosuppression therapy consisted of tacrolimus (Astellas Ireland Co., Ltd., Killorglin, County Kerry, Ireland) and mycophenolate mofetil (Roche România S.R.L, Bucharest, Romania) according to the local protocol. Despite the persistent negative PCR results for SARS-CoV-2 in the upper airway tract, the blood titer of neutralizing antibodies turned out positive on postoperative day 7. The patient had a favorable outcome, and she was discharged from the ICU facility seven days later. (3) Conclusions: We illustrated a case of liver transplantation of a SARS-CoV-2 negative recipient, whose donor was SARS-CoV-2 positive, performed in a tertiary, university-affiliated national center of liver surgery, with a good outcome, in order to raise the medical community awareness on the acceptance limits in the case of COVID-19 incompatibility for non-lung solid organs transplantation procedures.

Long-term methotrexate (MTX) treatment is known to cause MTX-associated lymphoproliferative disorder (MTX-LPD). A 58-year-old woman with psoriasis vulgaris and pityriasis rubra pilaris was treated with a combination of MTX and ustekinumab for 4 months when she developed generalized lymphadenopathy. The initial histopathological analysis indicated Hodgkin's lymphoma; however, assessing the patient's clinical history revealed the diagnosis of MTX-LPD. To our knowledge, this is the first case of a MTX-LPD after only 4 months of treatment.

Sarcoidosis and berylliosis (chronic beryllium disease, CBD) are granulomatous diseases and are phenocopies which cannot be differentiated based on the clinical presentation. Whereas for sarcoidosis the eliciting agent is unknown, for berylliosis an exposure to beryllium (mostly as occupational exposure) can be confirmed that therefore induces a sensitization against beryllium. The diagnosis is generally made in patients with a typical clinical presentation, the histological proof of a non-necrotizing granuloma and the exclusion of other diseases causing granulomas. In most cases, granulomas can be detected in the lungs and/or (intrathoracic) lymph nodes. The proof of sensitization to beryllium for the differential diagnosis can be performed with a so-called beryllium lymphocyte proliferation test in peripheral mononuclear blood cells or cells from a bronchoalveolar lavage. The objectives of treatment are avoidance of functional organ impairment and symptom control. Immunosuppressive therapy (initially mostly with corticosteroids) and supportive measures can prove beneficial; however, in many cases clinical observation can be sufficient because of stable disease or spontaneous resolution. In addition, further beryllium exposure must be avoided, which mostly necessitates a change of the workplace.

No agreement had been reached on the treatment of patients with pure red cell aplasia (PRCA) secondary to indolent malignancies. Data was collected from patients with acquired PRCA from May, 2014 to May, 2018 in Peking Union Medical College Hospital. Tumor-associated PRCA and primary PRCA patients were matched at a ratio of 1:2 with compatible baseline characteristics. All patients had been treated with CsA or sirolimus for at least 6 months with the efficacy and adverse events recorded. Twelve tumor-associated PRCA patients (3 thymoma, 8 lymphoproliferative disorders, and 1 smoldering multiple myeloma) with stable underling disease and 24 acquired primary PRCA patients were selected. 83.3% tumor-associated PRCA patients and 100% primary PRCA patients (P = 0.436) responded to immunosuppression therapy (IST) at a median of 2.5 and 3.5 months (P = 0.137), respectively. No different was found in side effects. The ORR at the end of a median of 21.5-month follow-up was 75% and 70.8% (P = 0.795), respectively. No tumor progression was reported except one secondary patient had lymphoma relapse after 2 years of IST and was given chemotherapy again. These results suggested IST had similar effect, safety on patients with tumor-associated, and primary PRCA patients when the tumors were stable.

BACKGROUND: Hypereosinophilic syndrome (HES) is a very rare disease and usually treated with corticosteroids. Gastrointestinal (GI) cytomegalovirus (CMV) infection is also rare but frequent in patients with immunocompromised status. These two related diseases present with similar manifestations, and may result in a life-threatening complication: perforation. However, the treatment strategies differ greatly. Here, we report a case of colon perforation due to cytomegalovirus infection in a patient with idiopathic HES. CASE PRESENTATION: A 41-year-old man with a history of HES was transferred to our hospital due to an acute onset of abdominal pain. During the treatment course of HES, this patient received CMV-DNA test with a result of < 2000 copies/ml. Computed tomography (CT) suggested colon perforation. An emergency surgery was performed immediately. Pathological diagnosis revealed CMV infection and infiltration of eosinophils. This patient received both anti-CMV therapy and immunosuppression therapy. Subsequently, the patient recovered and was discharged 25 days after the operation. CONCLUSION: During the course of HES treatment, CMV infection should be reconsidered if digestive symptoms relapse.

PURPOSE OF REVIEW: This review provides an overview of neuromuscular side effects associated with statin use, their diagnosis, and treatment. RECENT FINDINGS: The discovery of anti-HMGCR antibodies led to a better understanding of clinical aspects of statin-associated anti-HMGCR myopathy and its treatment. Statins are widely prescribed medications with well-established benefits in the treatment of cardiovascular diseases and stroke. Adherence to statins is influenced by development of side effects, especially muscle related. There is wide range of neuromuscular side effects associated with statin therapy. Documented neuromuscular side effects include asymptomatic elevation of muscle enzymes, mild-moderate myalgias and cramps, toxic and immune-mediated severe necrotizing myopathy, and rare cases of rhabdomyolysis. In addition, statins can lead to unmasking or triggering of underlying muscle and neuromuscular junction disorders. This article identifies the risk factors and provides a review of neuromuscular side effects associated with statin use, their diagnosis and treatment.

PURPOSE: To report a patient with thymoma-associated retinopathy presenting as having a good visual prognosis. METHODS: Case report and literature review. CASE REPORT: A 42-year-old female patient was referred to our hospital for complaints of sudden visual-field defects bilaterally. Decimal corrected visual acuity (VA) was 1.5 and 1.2 in the right (RE) and left eyes (LE), respectively. Fundus autofluorescence revealed hyper-autofluorescence from the posterior pole to mid-peripheral retina in both eyes. Full-field electroretinography (ERG) amplitudes were reduced to 20-50% and 30-50% of our controls for the scotopic and photopic conditions, respectively. A systemic examination revealed the presence of thymoma, and the patient underwent thymectomy and immunosuppression therapies. Immunohistochemical analysis using the patient's serum showed immunolabeling on the photoreceptor inner segment and outer plexiform layer in the monkey retina. Two years later, VA remained at 1.5 and 1.2 in RE and LE. ERG amplitudes improved to 30-60% of the controls for the scotopic conditions. However, photopic ERG showed no remarkable change. CONCLUSIONS: To our knowledge, improvement of reduced rod-mediated ERG responses has not been described in seven previously reported patients with thymoma-associated retinopathy. The good visual prognosis of our patient may be associated with well-timed intervention.
