Sarcoidosis With COVID-19

Several  post-COVID-19  inflammatory  disorders  and  autoimmune  diseases  have  been  discovered [1]  since  global  COVID-19  pandemic  started [2].  Association  between  these  diseases  is  still  to  be  investigated [2].  Common  genes  between  COVID-19  and  sarcoidosis  are  demonstrated  in  Figure 1, 2 [3].  Nevertheless, sarcoidosis  organ  involvement, demographics, and  type  of  sarcoidosis  treatment  at  the  time  of  COVID-19  diagnosis  are  related  to  hospital  admission, non-invasive  ventilation  or  high  flow  oxygenation, intubation [4].   A  retrospective  hospital-based  cohort  study  of  585  French  sarcoidosis  patients  in  2017, demonstrated  an  estimate  of  a  5 %  frequency  of  severe  infections  that  resulting  in  hospital  admission  and  death [5].  A typical HRCT feature in sarcoidosis is the presence of well-defined micronodules scattered along the broncho-vascular bundle, veins, fissures and pleura in a characteristic lymphatic distribution. Occasionally, “ galaxy  sign ”,a  highly  suggestive  of  pulmonary  sarcoidosis (predominance  of  a  mid-to-upper  lung  zones)  may  demonstrates  conglomerate masses that  are surrounded by a multitude of micronodules (Figure  3) [6].

Where VDR dominantly connected to 14 different kinds of drug, protein drug interaction network collected from DrugBank  provides  proper  treatment. Vitamin D and some of its analogous compounds might play significant roles in modulating both COVID-19 and sarcoidosis conditions  is  indicated  by  this  network (Figure  4) [3].

Besides  sarcoidosis  of  lungs, symptomatic  and  accidental  extrapulmonary  sarcoidosis  is  also  found  around  the  world (Figure  5, 6, 7) [7-9]. 

In  conclusion, hub  gene  identification  might  have  significant  roles  in  modulating  sarcoidosis  and  COVID-19  infection.  In  the  literature, cases  with  sarcoid-like  granuloma  have  been  reported  very  few.  Sarcoid-like  immune  response  to  COVID-19  could  be  noncaseating  granulomas  due  to  short  time  from  disease  to  develop  granuloma. 


Figure  1 :  Demonstrating  a Venn diagram of commonly differentially expressed upregulated genes. Common 34 upregulated genes were identified from 2320 upregulated genes of COVID-19 infection and 227 upregulated genes of sarcoidosis [3].

Figure  2 :  Demonstrating  protein-protein interactions (PPIs) network for common upregulated genes from COVID-19 and sarcoidosis. The light green color nodes indicate common upregulated genes. Network consists of 32 nodes and 102 edges [3].

Figure  3  :  Demonstrating  irregularly marginated nodule surrounded by multiple small nodules (“Galaxy sign”, yellow narrow), this is typical of sarcoidosis (a); ground-glass-like increased attenuation resulting from diffuse micronodules randomly distributed (“Miliary sarcoidosis”) (b); enlarged and partially calcified (yellow narrows) bilateral hilar lymph nodes (c); fibrotic sarcoidosis with cystic changes and traction bronchiectases (yellow narrows) predominantly in the perihilar region and upper lobes. Nodular abnormalities are minimal/absent, but the appearance and the location of the fibrosis are very suggestive of the diagnosis of sarcoidosis (d) [6].
