ABSTRACT
COVID-19 is a treacherous disease, in which infected patients who appear to fare well can deteriorate rapidly, mostly due to respiratory failure. For general practitioners (and other first-line responders), a clinical evaluation at any given time merely provides a snapshot of the patient's condition. Therefore, frequent monitoring is warranted in at-risk patients. However, there is no one-size-fits-all approach for monitoring, treatment and referral decisions. This is particularly the case in patients with advanced age. In this article, through the use of case examples, we aim to provide guidance when facing difficult management decisions in patients with (suspected) COVID-19.

Pulmonary hypertension (PH) is a severe complication of sarcoidosis, with an unknown prevalence. The aetiology is multifactorial, and the exact mechanism of PH in the individual patient is often difficult to establish. The diagnostic work-up and treatment of PH in sarcoidosis is complex, and should therefore be determined by a multidisciplinary expert team in a specialised centre. It is still a major challenge to identify sarcoidosis patients at risk for developing PH. There is no validated algorithm when to refer a patient suspected for PH, and PH analysis itself is difficult. Until present, there is no established therapy for PH in sarcoidosis. Besides optimal treatment for sarcoidosis, case series evaluating new therapeutic options involving PH-targeted therapy are arising for a subgroup of patients. This review summarises the current knowledge regarding the aetiology, diagnosis and possible treatment options for PH in sarcoidosis.
ABSTRACT
Chronic pulmonary thromboembolic disease is an important cause of severe pulmonary hypertension, and as such is associated with significant morbidity and mortality. The prognosis of this condition reflects the degree of associated right ventricular dysfunction, with predictable mortality related to the severity of the underlying pulmonary hypertension. Left untreated, the prognosis is poor. Pulmonary endarterectomy is the treatment of choice to relieve pulmonary artery obstruction in patients with chronic thromboembolic pulmonary hypertension and has been remarkably successful. Advances in surgical techniques along with the introduction of pulmonary hypertension-specific medication provide therapeutic options for the majority of patients afflicted with the disease. However, a substantial number of patients are not candidates for pulmonary endarterectomy due to either distal pulmonary vascular obstruction or significant comorbidities. Therefore, careful selection of surgical candidates in expert centres is paramount. The current review focuses on the diagnostic approach to chronic thromboembolic pulmonary hypertension and the available surgical and medical therapeutic options.
ABSTRACT
Klinefelter syndrome (KS) is a frequent genetic disorder due to one or more supernumerary X chromosomes. KS is associated with an increased risk for venous thromboembolic events like deep venous thrombosis and pulmonary embolism. This paper describes a 37-year-old male patient with KS referred to our tertiary center with chronic thromboembolic pulmonary hypertension, and who was successfully treated by pulmonary endarterectomy.
ABSTRACT
Chronic thromboembolic pulmonary hypertension (CTEPH) is a rapidly progressive and deadly disease, resulting from incomplete resolution of acute pulmonary embolism. Historically, the incidence of CTEPH was significantly underestimated but it may be as high as 3.8% following acute pulmonary embolism. Although the medical management of CTEPH may be supportive, the only curative treatment is pulmonary endarterectomy (PEA). However, a careful screening programme is mandatory to select CTEPH patients who are likely to benefit from PEA. In this review we discuss the pathophysiology, clinical and diagnostic pitfalls, surgical treatment, outcome after surgery, and the potential benefit of medical treatment in inoperable CTEPH patients.
ABSTRACT
GBV-C/Hepatitis G virus (GBV-C/HGV) is a newly discovered viral agent, found widely among healthy blood donors and among individuals at risk of parenterally transmitted infections. GBV-C/HGV is found frequently in coinfection with HCV. A population of 109 HCV positive patients was examined for the presence of GBV-C/HGV RNA and antibodies to E2. Of the 109 patients, 23 (21%) had serum GBV-C/HGV RNA in serum, 39 (36%) had only antibodies to E2 and 8 (7%) were positive for both markers, with an overall prevalence of 64%. Different serologic and virological patterns were observed in GBV-C/HGV exposed patients according to their infection status. Active infection was characterized by positive RT/PCR signal with primers for both the 5'UTR and NS5 genomic regions, viremia levels above 10(4) copies/mL by real time quantitative RT/PCR and absence of detectable anti-E2. In the transition phase between active infection and recovery, GBV-C/HGV RNA was only detectable by RT/PCR using primers from the 5' untranslated region and viremia levels were below 10(4) copies/ml by quantitative PCR, with or without simultaneous presence of anti-E2 antibodies. Resolved infection was characterized by absence of detectable viremia and, in most patients, by the presence of anti-E2.
