BACKGROUND AND OBJECTIVESMiddle Eastern respiratory syndrome caused by novel coronavirus (MERS CoV) has been a major public health challenge since it was first described in 2012 in Saudi Arabia. So far, there is no effective treatment for this serious illness, which features a high mortality rate. We report an initial experience of the use of ribavirin and interferon (IFN)-α2b in the management of MERS CoV at a tertiary care hospital.DESIGN AND SETTINGSA case series of 6 patients admitted with a confirmed diagnosis of MERS CoV were treated with ribavirin and IFN-α2b in addition to supportive management. The patients’ demographics, clinical parameters, and outcomes were recorded. Fifty-four close contacts of these patients were screened for MERS CoV.METHODSSix patients with MERS CoV infection were included in this study. Four cases featured symptomatic disease, including pneumonia and respiratory failure, while 2 were asymptomatic close contacts of the MERS CoV patients. The MERS CoV infection was confirmed by reverse transcription–polymerase chain reaction detection of the consensus viral RNA targets upstream of the E gene (UPE) and open reading frame (ORF1b) on a sputum sample. The patients’ demographics, comorbid conditions, time to diagnosis and initiation of treatment, and clinical outcomes were recorded.RESULTSThree out of 6 patients who had comorbid conditions died during the study period, while 3 had successful outcomes. The diagnosis and treatment was delayed by an average of 15 days in those patients who died. Only 2 close contacts out of the 54 screened (3.7%) were positive for MERS CoV.CONCLUSIONTreatment with ribavirin and IFN-α2b may be effective in patients infected with MERS CoV. There appears to be a low infectivity rate among close contacts of MERS CoV patients.
BackgroundChronic thromboembolic pulmonary hypertension (CTEPH) is a rare, progressive vascular disease with poor prognosis if left untreated. This study aims to assess the patient characteristics, treatment approach and clinical and survival outcomes for CTEPH patients enrolled in the Systematic Prospective Follow Up for Better Understanding of Clinical Characteristics of Patients with Pulmonary Hypertension Disease (SAUDIPH) registry.MethodsThis study presents a subanalysis of CTEPH patients enrolled in the SAUDIPH registry. This registry enrolled patients with pulmonary hypertension, established through right heart catheterisation, under clinical management at a specialised tertiary care centre. Patients received standard care during the period of the registry.ResultsAt the time of this analysis, 64 CTEPH patients were enrolled in the registry. Mean age at diagnosis was 39.7 years and there was a female predominance (67.6%). At baseline, most patients were in World Health Organization functional classes III or IV (70.1%). At the last follow-up visit, most patients (63.2%) had undergone endarterectomy, showing significant improvement in disease severity from baseline. Patients who underwent endarterectomy showed numerically higher (p=0.126) probability of survival at 1 year (97.5%) versus those who did not undergo endarterectomy (94.4%).ConclusionPatients were diagnosed at relatively young age, but still showed high disease severity, suggesting delay in diagnosis. Patients who underwent surgical treatment showed substantial improvements in clinical and haemodynamic parameters, while the remaining patients tended to show disease progression. The 96.6% 1-year cumulative probability of survival was high compared to previous studies.

Background and objective This study presents the first results of ‘SAUDIPH’ registry, aiming to assess patient characteristics, treatment approach and clinical and survival outcomes in patients with PAH. Methods The registry enrolled patients with Group 1 and Group 4 PH under clinical management in a specialized tertiary care centre from 2004 to 2018. Changes from baseline to last follow‐up visit were assessed. Results A total of 222 patients were enrolled, and Group 1 PH was the most frequent aetiology (57.7%). Mean age at diagnosis was 32 years. mPAP was 55.0 mm Hg and was higher for Group 1 PH (59.0 mm Hg, P < 0.001). At the last visit, most patients were on specific therapy (83.7%) and 30% shifted from FC III/IV to FC I/II. NT‐proBNP improved by 29.2% in the overall population. The 1‐, 3‐ and 5‐year cumulative probabilities of survival were 95.6% (95% CI: 91.5–99.9%), 89.2% (95% CI: 82.1–96.9%) and 74.6% (95% CI: 59.4–93.7%), respectively. CHD‐PAH demonstrated the best survival among Group 1 PAH with 1‐, 3‐ and 5‐year cumulative probability of 100%, 100%, and 75.0% (95% CI: 42.6–100), respectively. Conclusion PAH was the most frequent aetiology and patients were younger at diagnosis compared to other cohorts. Most patients showed improvement in FC and NT‐proBNP. The estimated 1‐year survival was better than previous studies, possibly reflecting wider use of combination therapy and the high prevalence of CHD‐PAH.
