Exploring the Clinical Variables among Drug-Dependent HIV-Positive Patients: Implications for Treatment Strategies

This study explored the profile of HIV positive patients seeking treatment at a tertiary care addiction treatment facility. A retrospective study was done to collet detailed information on clinical characteristics: drug use (type, age of initiation, duration), general medical condition and past treatment history. The study included 138 patients with mean (SD) age 30.2 (8.3) years. Opioid dependence with injecting drug use (IDU) was diagnosed in 97% of the patients. The median age of injecting onset was 24.5 years (IQR 20-31 years). The most frequently injected substances were pheniramine (60.1%) and buprenorphine (59.4%). Past treatment seeking was reported by 57% patients and interestingly they were less likely to present any medical condition (2 =69.611, p < 0.001). Variability in the age of onset of drug use indicates the need for broad based approach to prevent IDU and motivation to seek treatment may lead to better health conditions.

Escitalopram Induced Hyponatremia

National and international pharmacovigilance committee reports and case-control studies also implicate paroxetine, fluoxetine, sertraline. However, there have been only few reported cases of hyponatremia associated with escitalopram. The objective of this case report is to highlight a strong association of hyponatremia and SIADH (Syndrome of Inappropriate ADH secretion) in a middle-aged patient receiving escitalopram, a drug less commonly known to cause such side effects. Methods: We report a case of escitalopram induced severe hyponatremia in a middle-aged man where the association of hyponatremia with escitalopram is clearly established. Patient developed hyponatremia on the rechallenge with escitalopram (serum sodium = 94 mEq/L) within two days of initiation of treatment. The patient was free from other medical illnesses and was not taking other medications known to cause hyponatremia (confounders present in previous case reports suggesting an association between escitalopram and SIADH). Results: Our case suggests a strong association of escitalopram use and development of hyponatremia and SIADH in the absence of another drug use and medical comorbidity. Conclusion: Escitalopram, an SSRI is associated with hyponatremia and SIADH even in middle-aged individuals. There is a need for case-control studies especially involving a younger and middle age group. ASEAN Journal of Psychiatry, Vol. 17 (2): July – December 2016: XX XX.
