Temporal relationship between sarcoidosis and malignancies in a nationwide cohort of 1942 patients.

PURPOSE: To investigate the phenotype of sarcoidosis according to the time when a malignancy is diagnosed (preexisting to the diagnosis of sarcoidosis, concomitant, or sequential) and to identify prognostic factors associated with malignancies in a large cohort of patients with sarcoidosis. METHODS: We searched for malignancies in the SARCOGEAS cohort, a multicenter nationwide database of consecutive patients diagnosed with sarcoidosis according to the ATS/ESC/WASOG criteria. Solid malignancies were classified using the International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) nomenclature, and hematological malignancies using the 2016 WHO classification. We excluded patients with a biopsy-proven diagnosis of sarcoidosis based exclusively on demonstrating granulomas in tissues also involved by malignant cells. RESULTS: Out of 1942 patients with sarcoidosis, 233 (12%) developed 250 malignancies, including solid (n = 173), hematological (n = 57), and both types of malignancies (n = 3). Concerning the time interval between the diagnoses of both conditions, 83 (36%) patients were diagnosed with malignancy at least 1 year before sarcoidosis diagnosis, 22 (9%) had s synchronous diagnosis of both diseases, and 118 (51%) developed malignancies at least 1 year after the diagnosis of sarcoidosis (the remaining cases developed malignancies in different time intervals). The multivariate-adjusted model showed that individuals with sarcoidosis who developed a malignancy had an hazard ratio (HR) of 2.27 [95% confidence interval (CI), 1.62-3.17] for having an asymptomatic clinical phenotype at diagnosis of sarcoidosis and that spleen (presence vs. absence: HR = 2.06; 95% CI, 1.21-3.51) and bone marrow (presence vs. absence: HR = 3.04; 95% CI, 1.77-5.24) involvements were independent predictors for the development of all-type malignancies. No predictive factors were identified when the analysis was restricted to the development of solid malignancies. The analysis limited to the development of hematological malignancies confirmed the presence of involvement in the spleen (HR = 3.73; 95% CI, 1.38-10.06) and bone marrow (presence vs. absence: HR = 8.00; 95% CI, 3.15-20.35) at the time of sarcoidosis diagnosis as predictive factors. CONCLUSION: It is essential to consider the synchronous or metachronous timing of the diagnosis of malignancies in people with sarcoidosis. We found that half of the malignancies were diagnosed after a diagnosis of sarcoidosis, with spleen and bone marrow involvement associated with a four to eight times higher risk of developing hematological malignancies. Key messages What is already known on this topic Malignancies are one of the comorbidities more frequently encountered in people with sarcoidosis What this study adds Malignancies occur in 12% of patients with sarcoidosis Malignancy may precede, coincide with, or follow the diagnosis of sarcoidosis One-third were identified before sarcoidosis, and half were diagnosed after Spleen and bone marrow involvement are risk factors for developing hematological malignancies How this study might affect research, practice or policy Patients with sarcoidosis should be regularly monitored for neoplasms, informed of the increased risk, and educated on early detection. Those with spleen or bone marrow involvement must be closely followed.

Corticosteroids and other immunosuppressants for immune-related adverse events and checkpoint inhibitor effectiveness in melanoma.

BACKGROUND: Recent studies indicate an association between immunosuppression for immune-related adverse events (irAEs) and impaired survival in patients who received immune checkpoint inhibitors. Whether this is related to corticosteroids or second-line immunosuppressants is unknown. In the largest cohort thus far, we assessed the association of immunosuppressant type and dose with survival in melanoma patients with irAEs. METHODS: Patients with advanced melanoma who received immunosuppressants for irAEs induced by first-line anti-PD-1 ± anti-CTLA-4 were included from 18 hospitals worldwide. Associations of cumulative and peak dose corticosteroids and use of second-line immunosuppression with survival from start of immunosuppression were assessed using multivariable Cox proportional hazard regression. RESULTS: Among 606 patients, 404 had anti-PD-1 + anti-CTLA-4-related irAEs and 202 had anti-PD-1-related irAEs. 425 patients (70 %) received corticosteroids only; 181 patients (30 %) additionally received second-line immunosuppressants. Median PFS and OS from starting immunosuppression were 4.5 (95 %CI 3.4-8.1) and 31 (95 %CI 15-not reached) months in patients who received second-line immunosuppressants, and 11 (95 %CI 9.4-14) and 55 (95 %CI 41-not reached) months in patients who did not. High corticosteroid peak dose was associated with worse PFS and OS (HRadj 1.14; 95 %CI 1.01-1.29; HRadj 1.29; 95 %CI 1.12-1.49 for 80vs40mg), while cumulative dose was not. Second-line immunosuppression was associated with worse PFS (HRadj 1.32; 95 %CI 1.02-1.72) and OS (HRadj 1.34; 95 %CI 0.99-1.82) compared with corticosteroids alone. CONCLUSIONS: High corticosteroid peak dose and second-line immunosuppressants to treat irAEs are both associated with impaired survival. While immunosuppression is indispensable for treatment of severe irAEs, clinicians should weigh possible detrimental effects on survival against potential disadvantages of undertreatment.

Enfermedad de Castleman, fisiopatología, avances en el diagnóstico y tratamiento / Castleman's disease, pathophysiology, advances in diagnosis and treatment

La enfermedad de Castleman (EC) engloba a un conjunto heterogéneo de procesos linfoproliferativos que comparten rasgos histológicos bien definidos. Se considera una enfermedad rara o minoritaria u su incidencia no es del todo conocida, aunque se estima en menos de uno por cada 100.000 habitantes. Tiene una distribución bimodal (30-40 años y luego los 60-80 años). Su incidencia es similar en ambos sexos, aunque la variante unicéntrica parece tener ligero predominio en mujeres con proporción 2:1. La EC se clasifica en una forma hialinovascular (siendo esta la más frecuente) y otra plasmocelular, relacionadas con el virus de la inmunodeficiencia humana (VIH) y el virus herpes humano tipo 8 (VHH-8), que junto a otros mecanismos autoinmunitarios desarrollan la hiperproducción de interleucina-6 (IL-6) por parte de los linfocitos B. Existen diferentes líneas de tratamiento, donde destaca el uso de anti IL-6, siendo el siltuximab el más utilizado y catalogado como el fármaco huérfano de esta patología.(AU)

Castleman's disease (CD) encompasses a heterogeneous set of reactive lymphoproliferative processes that share well-defined histologic features. CD is considered a rare or minority disease. The incidence of CD is not fully known, although it is estimated at less than 1 per 100,000 inhabitants. It has a bimodal distribution (30–40 years and then 60–80 years). The incidence is similar in both sexes, although the unicentric variant seems to have a slight predominance in women with a 2:1 ratio. CD is classified into a hyalinovascular form (this being the most frequent) and a plasmocellular form, related to the HIV and VHH-8 viruses, which together with other autoimmune mechanisms develop hyperproduction of interleukin-6 (IL-6) by B lymphocytes. There are different lines of treatment, where the use of anti IL-6 stands out, being siltuximab the most used as orphan drug in this pathology.(AU)

Characterisation of the coexistence between sarcoidosis and Sjögren's syndrome. Analysis of 43 patients.

OBJECTIVES: To characterise the key epidemiological, clinical, immunological, imaging, and pathological features of the coexistence between sarcoidosis and Sjögren's syndrome (SS). METHODS: All centres included in two large multicentre registries (the Sjögren Syndrome Big Data Consortium and the Sarco-GEAS-SEMI Registry) were contacted searching for potential cases of coexistence between SS and sarcoidosis seen in daily practice. Inclusion criteria were the fulfilment of the current classification criteria both for SS (2016 ACR/EULAR) and sarcoidosis (WASOG). The following features were considered for evaluating a coexisting immunopathological scenario between the two diseases: non-caseating granulomas (NCG), focal lymphocytic sialadenitis (FLS) and positive anti-Ro antibodies. RESULTS: We identified 43 patients who fulfilled the inclusion criteria (38 women, with a mean age of 53 years at diagnosis of SS and of 52 years at diagnosis of sarcoidosis). In 28 (65%) cases, sarcoidosis was diagnosed concomitantly with SS, or during the follow-up of patients with an already diagnosed SS, while in the remaining 15 (35%), SS was diagnosed during the follow-up of an already diagnosed sarcoidosis. Patients in whom sarcoidosis was diagnosed first showed a lower mean age (43.88 vs. 55.67 years, p=0.005) and were less frequently women (73% vs. 96%, p=0.04) in comparison with those in whom sarcoidosis was diagnosed concomitantly with SS, or during the follow-up of an already diagnosed SS. We identified the following immunopathological scenarios: a combination of NCG involving extrasalivary tissues and anti-Ro antibodies in 55% of patients, a coexistence of both pathological scenarios (extrasalivary NCG and FLS in MSGB) in 42% (with positive anti-Ro antibodies in two thirds of cases), and NCG involving salivary glands and anti-Ro antibodies in 3% of cases. CONCLUSIONS: We have characterised the largest reported series of patients who fulfilled the current classification criteria for both SS and sarcoidosis. This implies that sarcoidosis (and not just the presence of isolated NCG on salivary gland biopsy) may, like other systemic autoimmune diseases, coexist with SS, and that a sarcoidosis diagnosis does not preclude the development of SS in the future.

Therapy-resistant dermatomyositis with extensive 'lumbar belt' calcinosis.

Calcinosis cutis (CC) is the umbrella term for calcium salt deposition on skin and subcutaneous tissue. We present a unique case of CC associated with anti-Mi2-positive dermatomyositis, having a distinctive distribution of subcutaneous calcifications appearing as a 'lumbar belt'. Treatment of CC remains challenging for clinicians due to a lack of high-quality evidence. Corticosteroids, methotrexate, bisphosphonates, intravenous immunoglobulin replacement, rituximab and sodium thiosulfate failed to halt calcinosis progression in this case. Newer therapies, such as Janus kinase inhibitors, should be considered.

Cutaneous and Ganglion Sarcoidosis Induced by Polycaprolactone Facial Filler: A New Expression of ASIA Syndrome?

Dermal fillers are applied using a minimally invasive technique with a good safety profile. However, they can have side effects. We present the case of a patient who, 2 months after undergoing polycaprolactone (Ellansé®) injections, developed nodular facial and nodal lesions that were compatible with sarcoidosis on histology. This complication has not been previously described for polycaprolactone and could be the expression of an autoimmune syndrome induced by adjuvants. LEARNING POINTS: Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) is a recently devised umbrella term for autoimmune diseases caused by adjuvants.Aesthetic procedures, which are increasingly common, may be a cause of ASIA syndrome.Polycaprolactone is a bioabsorbable polymer with a safe profile but can have adverse events, including systemic sarcoidosis.

Clinical characterization and outcomes of 85 patients with neurosarcoidosis.

To analyze the frequency and clinical phenotype of neurosarcoidosis (NS) in one of the largest nationwide cohorts of patients with sarcoidosis reported from southern Europe. NS was evaluated according to the Diagnostic Criteria for Central Nervous System and Peripheral Nervous System Sarcoidosis recently proposed by Stern et al. Pathologic confirmation of granulomatous disease was used to subclassify NS into definite (confirmation in neurological tissue), probable (confirmation in extraneurological tissue) and possible (no histopathological confirmation of the disease). Of the 1532 patients included in the cohort, 85 (5.5%) fulfilled the Stern criteria for NS (49 women, mean age at diagnosis of NS of 47.6 years, 91% White). These patients developed 103 neurological conditions involving the brain (38%), cranial nerves (36%), the meninges (3%), the spinal cord (10%) and the peripheral nerves (14%); no patient had concomitant central and peripheral nerve involvements. In 59 (69%) patients, neurological involvement preceded or was present at the time of diagnosis of the disease. According to the classification proposed by Stern et al., 11 (13%) were classified as a definite NS, 61 (72%) as a probable NS and the remaining 13 (15%) as a possible NS. In comparison with the systemic phenotype of patients without NS, patients with CNS involvement presented a lower frequency of thoracic involvement (82% vs 93%, q = 0.018), a higher frequency of ocular (27% vs 10%, q < 0.001) and salivary gland (15% vs 4%, q = 0.002) WASOG involvements. In contrast, patients with PNS involvement showed a higher frequency of liver involvement (36% vs 12%, p = 0.02) in comparison with patients without NS. Neurosarcoidosis was identified in 5.5% of patients. CNS involvement prevails significantly over PNS involvement, and both conditions do not overlap in any patient. The systemic phenotype associated to each involvement was clearly differentiated, and can be helpful not only in the early identification of neurological involvement, but also in the systemic evaluation of patients diagnosed with neurosarcoidosis.

Disfunción tiroidea y lipídica asociada a bexaroteno en el linfoma cutáneo de células T / Thyroid and lipidic dysfunction associated with bexarotene in cutaneous T-cell lymphoma

Fundamento y objetivo: El bexaroteno es un rexinoide sintético selectivo del receptor X aprobado para el tratamiento sistémico del linfoma cutáneo de células T. Durante el tratamiento es muy frecuente la aparición de hipotiroidismo e hiperlipidemia mixta grave, siendo ambos efectos adversos reversibles y dependientes de la dosis. La elevación del colesterol LDL y los triglicéridos (hasta unos niveles aumentados que incluso se han asociado a pancreatitis en algunos casos) está ampliamente descrita (al igual que sucede con otros retinoides), siendo el descenso del colesterol HDL menos conocido. Revisamos nuestra experiencia con el uso de bexaroteno. Material y métodos: Se presenta una serie de 3 casos de pacientes tratados con bexaroteno en los que, además de sufrir los efectos adversos bien conocidos, se observó un grave descenso del colesterol HDL. Resultados: Los 3 pacientes estudiados presentaron complicaciones metabólicas en forma de hipotiroidismo central e hiperlipidemia mixta grave, con especial énfasis en el marcado descenso que experimentaron nuestros pacientes (descenso medio > 83%) en las cifras de colesterol HDL. El tratamiento hipolipidemiante y hormonal sustitutivo con levotiroxina dio lugar a una mejoría de los parámetros, sin llegar a alcanzarse los objetivos. Conclusiones: El bexaroteno produce, como efectos secundarios predecibles, una hiperlipidemia mixta grave con descenso marcado de los niveles de colesterol HDL e hipotiroidismo central, los cuales son reversibles y dependientes de la dosis. Se incluye una reflexión sobre los posibles mecanismos etológicos e implicaciones de este fenómeno (AU)

Background and objective: Bexarotene is a synthetic selective X receptor rexinoide approved for the systemic treatment of cutaneous T-cell lymphoma. During treatment is very frequent the occurrence of hypothyroidism and severe mixed hyperlipidemia, both are reversibles and dose-dependent adverse events. Increase of triglycerides and LDL-cholesterol level (up to even higher levels have been associated with pancreatitis in some cases) is widely described (as is the case with other retinoids) but decrease in HDL-cholesterol is poored know. We review our experience with the use of bexarotene. Material and methods: We present a serie of 3 clinical report of patients treated with bexarotene in whose, in addition to these well-known adverse event, a serious lowering of HDL-cholesterol was observed. Results: The 3 patients studied had metabolic complications like central hypothyroidism and severe mixed hyperlipidemia; with special emphasis on the sharp fall (mean decrease > 83%) in the HDL-cholesterol level. Cholesterol lowering medication and substitutive hormonal replacement with levotiroxine resulted in an improvement of the biochimical parameters without reaching the correct goals. Conclusions: Bexarotene produce as predictable side effects severe mixed hyperlipidemia with marked decrease in HDL-cholesterol levels and central hypothyroidism, being the both reversible and dose-dependent. A reflection on the possible aetiological mechanisms and implications of this phenomenon are included (AU)

[Clinical characteristics, cellular and molecular basis of hypertension in elderly]. / Características clínicas, bases celulares y moleculares de la hipertensión arterial del anciano.

The prevalence of arterial hypertensión (AH) increases with ageing, and, on the other hand, it acquires a series of clinical characteristics that differentiates it from AH in young persons or in subjects in average ages of the life. In the present article we will study several cellular or molecular mechanisms, which relate AH and aging. Moreover, we will discuss certain clinical peculiarities of AH in the elderly such as the relation with arterial stiffness and with isolated systolic hypertension. We will finalize proposing objectives of control of blood pressure in the elderly as well as marking strategies to delay, or prevent, the development of this, not always well-known, form of AH.
