Background: Methotrexate is considered as the anchor drug for the treatment of rheumatoid arthritis. However, various adverse effects limit its use leading to frequent discontinuation of treatment. This study aimed to evaluate the common adverse effects of methotrexate in patients with rheumatoid arthritis. Methods: A prospective observational study was conducted at National Center for Rheumatic Diseases from June 2018 to May 2019 among patients with rheumatoid arthritis using methotrexate monotherapy. Laboratory tests like liver function tests, renal function tests, complete blood count, C-reactive protein, erythrocyte sedimentation rate were done at baseline and every 3 months. Data on patients’ comorbidities, disease activity and side effects of drug were collected on every follow- up. Statistical analysis was carried out with the help of SPSS 23.0. Results: Out of 232 patients experiencing at least one adverse effect while on methotrexate monotherapy, 87.5% were female and mean age was 46.9±10.8 years. The mean dose of methotrexate was 16.6 ± 3.9 mg/week with the most frequently used dose of 20mg/week. Among the variety of adverse reaction observed, the most common was transaminitis (75.0%) with approximately 50.0% as isolated liver function abnormality, followed by nausea (19.4%), anorexia (12.9%), leukopenia (12.5%), oral ulcer (8.2%) and psychological intolerance (4.7%). Multiple regression analysis showed significant predictive value of body mass index for transaminitis (p-value 0.007). Conclusions: Asymptomatic liver function test derangement was the most frequent adverse-effect of methotrexate observed, whereas nausea and anorexia were the most common patient reported events. The frequent dose associated with side-effects in Nepalese patients was around 20mg/week. Keywords: Adverse events; methotrexate; Nepal; rheumatoid arthritis

Background. Gout is commonly associated with metabolic syndrome. Strong association between the serum uric acid level and microalbuminuria has also been observed in various studies. Aim. To observe the change in urinary microalbumin after urate-lowering treatment in patients with gout and microalbuminuria. Methodology. A prospective, observational study was conducted at a tertiary-level rheumatic center (NCRD) in Kathmandu, Nepal. Adults diagnosed with gout using the 2015 ACR/EULAR criteria and microalbuminuria were enrolled in the study after obtaining informed consent. Sociodemographic profile and clinical history were recorded at baseline. Serum uric acid levels, spot urinary microalbumin (MAU) excretion, blood sugar, lipid profile, and blood pressure were measured at baseline, 3-month follow-up, and 6-month follow-up. A paired t-test was used to compare the change in mean MAU after treatment. Results. A total of 778 patients diagnosed with gout were screened for microalbuminuria. Among them, 114 (14.6%) had urinary microalbumin levels of >30.0 mg/L during presentation. Mean MAU level among those with microalbuminuria was 132.4±124.6 mg/L. Thirty-five patients had concomitant HTN and were put on ARBs (20 mg of telmisartan). All received 40 mg of febuxostat. In patients with ARBs, MAU reduced significantly after 3 months of treatment with ARBs. Reduction in MAU in those without ARBs was seen after the 6-month follow-up, and the change was statistically significant. Conclusions. There is significant reduction in MAU after the use of urate-lowering drugs in patients with gout.
