Dear Editor,

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes adverse outcomes in those with prior medical comorbidities such as diabetes mellitus, hypertension, obesity, chronic kidney disease, and in the elderly.[1] Global registries such as the EULAR–COVID-19 database and COVID-19 Global Rheumatology Alliance aim to share outcomes of SARS-CoV-2 infection in rheumatological disorders.[2] However, there is a lack of data from South Asia. Patients with rheumatoid arthritis (RA) have a higher infection risk, due to disease process and drug therapy, more so with biologicals than with conventional disease-modifying anti-rheumatic drugs (DMARDs).[3] We report a case series of patients with RA, hospitalized for SARS-CoV-2 infection.

We retrospectively analyzed 9 hospitalized patients with prior seropositive RA with confirmed SARS-CoV-2 infection (by reverse transcriptase-polymerase chain reaction of naso-pharyngeal swab) between June 11 and September 30, 2020. The severity of RA was assessed using Disease Activity Score 28 at initial hospitalization.[4] SARS-CoV-2 infection was classified as mild (peripheral oxygen saturation > 94%), moderate (90%–94%), and severe (<90%). Patient characteristics including age, gender, clinical features, investigations, treatment, and course in the hospital were obtained.

The mean age was 54.5 ± 10.8 years. [Table 1] describes baseline characteristics, the severity of illness, and the management of individual patients. The mean duration of RA was 14.8 ± 3.6 years. Symptoms on presentation were fever (n = 7), cough (n = 4), shortness of breath (n = 3), sore throat (n = 3), myalgias, fatigue, and vomiting were observed in one each. The mean C-reactive protein was 3.5 ± 4.6 mg/dl, lactate dehydrogenase was 288.6 ± 73.6 U/L, ferritin 103.91 ± 112.04 ng/ml, serum albumin 3.7 ± 0.4 g/dl, d-Dimer 0.86 ± 0.57 mg/L, neutrophil-lymphocyte ratio was 3.3 ± 2.5, absolute lymphocyte count was 1810.8 ± 944.57 cells/cu mm. Four received steroids (methylprednisolone-2, prednisolone-1, and 1-dexamethasone) along with Zinc and Vitamin C supplementation. None received Remdesivir. DMARDs at dose taken by the patient before hospitalization was continued during the hospital stay. However, two patients had discontinued DMARDs before current illness and two were only on hydroxychloroquine as they were in clinical remission. The mean duration of hospital stay was 7.4 ± 2.7 days. Prolonged hospital stay, defined as >10 days, was required for 2 patients on account of hypoxia, none developed thrombosis or organ dysfunction. All were discharged to home.

Our case series shows favorable outcomes despite a high prevalence of additional prior medical illness (8 of 9 had at least one additional illness). Data from Europe suggest that outcomes of COVID are not influenced by preexisting rheumatological diseases.[5] The infection is known to result in the release of interleukins (IL) such as IL-6, IL-1, IL-8, and chemokines which activate macrophages and help their homing to inflammatory areas.[6] This cascade leads to increase in the production of macrophage inflammatory protein 1 alpha, tumor necrosis factor which results in tissue destruction. Activation of T cells, production of effector cytokine, and the influx of neutrophils are features of both synovitis due to RA and lung damage due to SARS-CoV-2 infection and DMARDs target several of these mediators.[6]

A recent meta-analysis observed that hydroxychloroquine/chloroquine does not reduce short-term mortality in patients hospitalized with COVID-19.[7] However, whether long term intake of disease-modifying agents help in downregulation of the cytokine and chemokine surge resulting in benefit in patients with rheumatological disorders is yet to be studied.
