Peritoneal Sarcoidosis Mimicking Peritoneal Tuberculosis and Advanced Ovarian Carcinoma. Case Rep Obstet Gynecol 2020; 2020:1905649. [PMID: 32695535 PMCID: PMC7361883 DOI: 10.1155/2020/1905649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Revised: 06/05/2020] [Accepted: 06/18/2020] [Indexed: 11/18/2022] Open
Abstract
Sarcoidosis is an inflammatory disease that affects one or multiple organs, most commonly the lungs and lymph nodes. This disease can present in a variety of ways which often makes diagnosis difficult. A 54-year-old postmenopausal African American female with a history of omental carcinomatosis of unknown origin was referred to the gynecology-oncology service at a local community hospital following a laparoscopic incarcerated hernia repair where multiple abdominal lesions suspicious of ovarian carcinomatosis were visualized. She was brought to the operating room for a diagnostic laparoscopy at which point the intra-abdominal survey revealed white tubercle-like lesions that were consistent with peritoneal tuberculosis. The lesions were excised and sent to pathology. The omentum biopsy was originally reported as adipose tissue showing focal fibrosis, focal mild acute inflammation, few cyst formation, and multiple granulomatous chronic inflammation, with multinucleated giant cells. Periodic acid-Schiff stain and acid fast bacilli stain were negative, and a diagnosis of peritoneal tuberculosis was made. The patient was started on an antituberculosis treatment regimen; however, she was not improving. The pathology slides were reexamined and revealed nonnecrotizing granulomatous inflammation consistent with sarcoidosis. The patient was immediately referred to the department of pulmonology and rheumatology, at which point she was started on corticosteroids and had an improvement in her condition.

Abstract
Sarcoidosis is a chronic granulomatous disease of unknown origin. There are several modalities for diagnosis, staging and therapeutic management of patients with sarcoidosis. Among these, whole-body F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography is found to useful in patients with complex and multisystem forms of sarcoidosis. Other modalities include Gallium scanning, assesment of angiotensin converting enzyme levels in blood, chest radiography, mediastinoscopy etcetera.

Abstract
PURPOSE OF REVIEW Increased familial occurrences as well as different disease modes in different ethnic groups suggest a genetic influence in sarcoidosis. Also, genetic analyses have revealed a number of chromosomal regions and specific genes associated with sarcoidosis. This review brings up some recent discoveries on the genetic contribution to sarcoidosis. RECENT FINDINGS As a more detailed clinical classification of patients is performed, stronger genetic associations between distinct clinical phenotypes and specific gene variants have been revealed. The strong association between human leucocyte antigen DRB10301/DQB10201 and good prognosis in patients with Löfgren's syndrome is one such recent example. Linkage studies have revealed certain chromosomal regions of interest and furthermore pointed out specific genes of interest, for example, a variant of the butyrophilin-like 2 gene. SUMMARY Sarcoidosis is a complex disease which is influenced by a multitude of genes and environmental factors. The strongest genetic associations are found within the human leucocyte antigen region, in which several specific human leucocyte antigen alleles clearly associate with disease risk and phenotype, but additional genes in the same region may turn out to be important as well. Future studies on large, clinically well defined patient cohorts will help to elucidate the genetic impact on sarcoidosis.

Abstract
A single nucleotide polymorphism (SNP) C5507G of the complement receptor 1 (CR1) gene has been associated with genetic susceptibility to sarcoidosis in an Italian population. In order to provide further data on the possible involvement of CR1 gene polymorphisms in sarcoidosis, CR1 SNPs C5507G and A3650G were investigated in Czech (n = 210) and Dutch (n = 116) patients with sarcoidosis with ethnically matched groups of healthy control subjects (Czech, n = 203; Dutch, n = 112). CR1 C5507G and A3650G SNPs were not associated with susceptibility to sarcoidosis or its clinical course. Further, CR1 messenger RNA expression in bronchoalveolar lavage cells investigated by quantitative reverse transcriptase-polymerase chain reaction did not differ between sarcoidosis patients and control subjects and was not associated with the presence of the CR1 5507*G allele.

Abstract
Pleural fibrosis resembles fibrosis in other tissues and can be defined as an excessive deposition of matrix components that results in the destruction of normal pleural tissue architecture and compromised function. Pleural fibrosis may be the consequence of an organised haemorrhagic effusion, tuberculous effusion, empyema or asbestos-related pleurisy and can manifest itself as discrete localised lesions (pleural plaques) or diffuse pleural thickening and fibrosis. Although the pathogenesis is unknown, it is likely that the complex interactions between resident and inflammatory cells, profibrotic mediators and coagulation, and fibrinolytic pathways are integral to pleural remodelling and fibrosis. It is generally considered that the primary target cell for pleural fibrosis is the subpleural fibroblast. However, increasing evidence suggests that mesothelial cells may also play a significant role in the pathogenesis of this condition, both by initiating inflammatory responses and producing matrix components. A greater understanding of the interactions between pleural and inflammatory cells, cytokines and growth factors, and blood derived proteins is required before adequate therapies can be developed to prevent pleural fibrosis from occurring.

Abstract
Five to 25% of patients with systemic sarcoidosis also have CNS involvement. Patients with systemic disease may initially present with neurologic symptoms, and rarely, the sarcoidosis may be isolated to the CNS. A typical imaging feature is thickening and enhancement of the basilar leptomeninges of the brain. Other imaging findings, such as enhancing or nonenhancing parenchymal lesions, dural, and bone lesions may occur in the head and spine. Because there is a high rate of progression and recurrence following treatment, imaging follow-up is recommended in all patients.

Abstract
Sarcoidosis is known to be a systemic granulomatous disorder characterized by a cell-mediated Th1-type inflammatory response. To identify a key genetic factor in the pathogenesis of sarcoidosis, we investigated single nucleotide polymorphisms within 10 candidate genes involved in type 1 immune process ( IFNA17, IFNB, IFNG, IFNGR1, IFNGR2, IL12B, IL12RB1, IL12RB2, ETA-1, and NRAMP1) in an association-based study of 102 Japanese patients with sarcoidosis, 114 with tuberculosis, and 110 control subjects. After correction for multiple testing, an IFNA17 polymorphism (551T-->G) was found to be associated with susceptibility to sarcoidosis (odds ratio 3.27 [95% CI: 1.44-7.46], P=0.004, P(c)=0.04), but not to tuberculosis. We observed no significant associations with the other polymorphisms of the Th1-related genes. We further typed another IFNA polymorphism ( IFNA10 60T-->A) and confirmed two major haplotypes of the IFNA gene, viz., allele 1: IFNA10 [60T]- IFNA17 [551T] and allele 2: IFNA10 [60A]- IFNA17 [551G], in the Japanese population. In healthy subjects, IFNA allele 2, which is over-represented in patients with sarcoidosis, was significantly associated with increased IFN-alpha and IL-12p70 production induced by Sendai virus in vitro. This study suggests that possession of the IFNA allele with higher levels of IFN-alpha significantly increases the risk of sarcoidosis.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic, fibrotic disorder underlain by aberrant wound healing of repeated lung injury. Environmental triggers and genetic background are likely to act as modifiers of the fibrotic response. Erythrocyte complement receptor 1 is a membrane protein mediating the transport of immune complexes to phagocytes. Three gene polymorphisms are related to the erythrocyte surface density of complement receptor 1 molecules, which in turn are related to the rate of immune complexes' clearance. There is evidence of association between sarcoidosis and the complement receptor 1 gene. We wondered whether IPF is associated with the complement receptor 1 gene alleles coding for a reduced molecule/erythrocyte ratio. We studied 74 patients and 166 control subjects. Three polymorphic sites of the gene, A3650G exon 22, HindIII RFLP intron 27, and C5507G exon 33, were analyzed and found to be in linkage disequilibrium. The GG genotype for the C5507G exon 33 polymorphism was significantly more common in patients with IPF than in control subjects (odds ratio = 6.232, 95% confidence interval = 2.198-18.419, p = 0.00023). The significant difference was found in both sexes. These findings agree with speculations on the role of the complement receptor 1 gene in idiopathic pulmonary fibrosis.

Abstract
Pulmonary fibrosis (PF) is caused by a number of inhaled agents, as well as by some drugs and toxic particles. The elaboration of certain peptide growth factors is thought to be key to the development of this disease process. In addition, genetic susceptibility plays a role in the development of PF. For instance, we have previously shown that the 129J strain of mice is resistant, whereas the C57BL/6 strain is highly susceptible, to asbestos-induced fibrosis. To pursue this further, in one mouse model, we crossed the 129J strain to the C57BL/6 strain to produce an F1 generation and subsequently backcrossed the F1 mice to the inbred founders. This backcross to the 129 inbred strain produced reverse similar 25% of the offspring with a phenotype that was protected from the fibrogenic effects of inhaled asbestos fibers. In the second model, both strains of mice were treated intratracheally with an adenovirus vector (AdV), which transduces expression of active transforming growth factor (TGF)-beta(1) in the lungs, producing fibroproliferative lung disease. Compared with C57 mice, a significant number of 129 strain mice exhibited at least a 1-wk delay in the fibroproliferative response to TGF-beta(1) expression at three concentrations of virus. These findings suggest that certain sequences in a gene or a cluster of genes in the 129 mouse strain impart a phenotype in which there is a delay in, or protection from, the development of lung fibrogenesis.
