Intravenous drug abusers are a patient population prone to prejudice and treatment bias, and doctors must prevent such discrimination and offer the best treatment possible. According to nursing studies, views about IVDU differ by clinical grade, with senior professionals having a more positive attitude toward IVDU. The kind of therapy given to our IVDU group at follow-up visits was similarly inconsistent. According to Lawson et al., getting the right length of treatment after a hospital stay may be difficult. The authors recommend six weeks of monitored LMWH usage in IVDU as a sensible approach to antithrombotic therapy [108].
Since the 1990s, it has been demonstrated that vascular complications including deep vein thrombosis (DVT) have high morbidity among intravenous drug users (IVDU). A study conducted in Glasgow by McColl et al. showed that 52.8 % of women under 40 years of age with confirmed DVT were IVDU and similar results were obtained by Syed et al. who found this association in 48.8% of patients from a similar sample [7,8]. Although knowledge of the exact mechanism behind this association is still limited, repeated trauma to the vein may be partly responsible along with the intrinsic properties of the injected substances and the acidity of some preparations [6-10]. The use of nonsterile injection equipment may account for a range of infections in IV drug users, including bacterial endocarditis, hepatitis, malaria, and cellulitis or soft tissue infections (Louria et al., 1967).
The most commonly occurring local symptoms were groin pain, swelling, erythema, elevated local temperature, and/or cyanosis or skin necrosis of the affected limb [15]. Because of easier access, the redistribution of stimulant substances’ production increases the risk of their use by IVDU in middle and low-income countries [26,28]. Septic pulmonary emboli can seed from injection-site infections and tricuspid valve endocarditis and usually present with high fever and symptoms suggestive of pulmonary emboli.11 Lung abscesses result typically from aspiration, frequently due to K pneumoniae13 or septic emboli. Although chest X-ray is sufficient to demonstrate the pulmonary infection in most cases, CT can be useful to confirm cavitation and the distribution of infection and to exclude pulmonary embolus. These data exclude individuals who report both IV drug use and homosexual behavior.
However, a 10-minute imaging procedure called magnetic resonance direct thrombus imaging (MRDTI) has been found to be superior to compression ultrasonography and capable of discriminating between acute and chronic thrombosis remnants. Withholding anticoagulation after a negative MRDTI scan resulted in a failure rate of 1.7% (95% CI), which was lower than the 6.5% predefined safety threshold value, proving that MRDTI was a simple, reproducible, and feasible test for diagnosis of recurrent venous thromboembolism [90]. For ruling out suspected DVT in pregnancy, iv drug use ultrasound proves to be an effective diagnostic test, based on a study revealing that a single negative ultrasound scan had a low false-negative rate [91]. In 2020, Kraaijpoel and his team demonstrated that all three imaging techniques, single limited vs. serial limited vs. whole-leg CUS, have equal failure rates. However, the relative failure rate of a single restricted CUS was unclear, making it only suitable for low-risk applications [92]. CUS was also recommended as the preferred diagnostic method in cancer patients by Takada et al. [93].
Shortening the overall length of treatment in IVDU may be helpful, but only if the acute phase is followed strictly and the higher risk of complications and disease recurrence is understood. Addiction treatment clinics that provide supervised thrombosis therapy with LMWH in addition to methadone/buprenorphine administration should be recommended to patients [ ]. There is presently no information on the usage of new oral antithrombotic medicines in IVDU with DVT. DVT therapy is now regulated by general population guidelines, which means that when antithrombotic medication is given to IVDU, all of the risks and restrictions described above must be taken into account [112]. In addition, local DVT treatment guidelines must be established for these individuals [15].
