ABSTRACT

The anticoagulants of choice for the prevention and treatment of venous thromboembolic disease during pregnancy are unfractionated heparin and low-molecular-weight heparin. Heparin-induced thrombocytopenia (HIT) is introduced as a rare but critical side effect of heparin products raising the thromboembolic event paradoxically. Here, we present a case of HIT in pregnancy with challenging management due to coincidence of lupus anticoagulant (LA) and limited anticoagulant options in the pharmaceutical market of our country of residence. We describe a 6-week pregnant patient with deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE), which developed HIT during antenatal care. Therapeutic anticoagulation was initiated with argatroban, then switched to apixaban due to limited access to argatroban. Another therapeutic challenge was the concurrent incidence of LA. The interdisciplinary care team decided on adding up warfarin and scheduled termination at 12 weeks regarding the hazardous condition of the patient. We also reviewed related case literature to convey a new insight into managing pregnancy-related HIT. HIT is a pro-coagulatory and lethal complication associated with heparin therapy that can be diagnosed by clinical suspicion, the 4T score system, and confirmatory laboratory analyses. Alternative anticoagulation is the cornerstone of the treatment and an interdisciplinary plan will be worthwhile to make the best clinical decision regarding the critical situation and least the thromboembolic events mortality during pregnancy.

ABSTRACT

BACKGROUND: During the ongoing COVID-19 pandemic, immunocompromised patients are at a higher risk of severe infection, since the immune system has an important role in defeating this disease. This study compares the severity of COVID-19 in patients taking methotrexate with the severity of their family members' illness as patients with normal immune system function. METHODS: A total of 35 participants, including 14 patients taking methotrexate and 21 patients with normal immune function, entered this study, and the indicators of COVID-19 severity were compared between these two groups. RESULTS: The case group, who were on methotrexate therapy, had significantly less severe COVID-19 based on their symptoms, including fever (p = 0.000) and cough and dyspnea (p = 0.01) as well as in terms of COVID-19 severity indicators such as pulmonary involvement (p = 0.001), ferritin level (p = 0.001), white blood cell count (p = 0.008) and CRP level (p = 0.006), compared to the control group. There was a significant correlation between taking methotrexate and lower severity in COVID-19 disease. CONCLUSION: The present findings demonstrated that methotrexate does not predispose patients to severe COVID-19; on the contrary, patients taking methotrexate may experience a milder disease, possibly due to their reduced severe inflammatory reactions as a result of inhibited TNFα, lowered IL6, and increased T regulatory cells. According to these findings, methotrexate appears to be a suitable treatment option for patients who need immunosuppressive medications during the COVID-19 pandemic.

ABSTRACT

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is an irreversible pulmonary obstruction. Respiratory exercise training by a feedback-based model besides the routine managements have been considered to perform. RESEARCH DESIGN AND METHODS: Eighty exacerbated COPD patients with informed consent were divided to the control group (n = 40) received the routine approach and the intervention group (n = 40) received a teach-back training method (TBTM) of respiratory exercise including diaphragmatic breathing (DB), pursed-lip breathing (PLB), and effective coughing (EC) plus routine approach. The clinical outcomes were evaluated by measurement of the FEV1/FVC ratio, the Borg scale of dyspnea (BSD), and the 6-minute walking test (6MWT) results at the baseline, just after TBTM, and next 3 months. RESULTS: FEV1/FVC ratio has been indicated the significant improvement followed by TBTM compare to the baseline (p < 0.001). Moreover, the BSD scores in 3-month follow-up after TBTM were significantly lower compared to the baseline (6 ± 1.3 vs. 3.8 ± 0.78, p < 0.001). Although a significant difference was reported in 6MWT distance between two groups after 3-month follow-up (p < 0.001), there was no significant difference immediately after the TBTM (p = 0.992) that suggested a long-term effect of educational intervention on physical activity. CONCLUSION: Significant enhancement in the clinical variables can demonstrate the efficacy of the TBTM program in reducing COPD patients' symptoms.
