Background: Idiopathic CD4 lymphocytopenia (ICL) is an underdiagnosed immunodeficiency syndrome characterised by persistent low CD4 counts in the absence of HIV and other causes of lymphocytopenia. ICL patients are susceptible to opportunistic infections, with human papillomavirus, cryptococcal, and tuberculosis being the most common infections reported. Nocardiosis is rarely reported in patient with ICL. Case Presentation: We herein discuss a 46-year-old female presented with complaints of weight loss, low grade fever and cough with expectoration from last four months. The patient was diagnosed with pulmonary nocardiosis and aspergillosis co-infection four years back; in addition she also had ICL. Subsequently, the patient was lost in follow-up and readmitted four years later. Bronchoalveolar lavage sample shows the presence of acid-fast bacilli in modified gram stain, which later identified as Nocardia otitidiscaviarum by metagenomic next-generation sequencing. Her CD4 counts were still found low (298 cells/mm3). After an initial improvement with trimethoprim-sulfamethoxazole (TMP-SMX), she was commenced on indefinite secondary prophylaxis. Conclusions: Nocardiosis without usual risk factors should be evaluated for ICL. This case emphasize the importance of periodic follow-up with CD4 count monitoring and secondary prophylaxis therapy to prevent recurrence or the emergence of new infections in ICL. Clinical trial number: Not applicable. [ABSTRACT FROM AUTHOR]

Background: Polypharmacy and inappropriate prescriptions are the most highlighted health issues among geriatric population, as they have multiple comorbidities. The objective of this study was to assess prescriptions using the World Health Organization (WHO) core indicators and Beers Criteria to discover polypharmacy and inappropriate prescriptions. Methods: This was a prospective, cross-sectional study of geriatric patients (65 years and above) who were attending the medicine outpatients clinic of a tertiary care teaching hospital hospital from May to December, 2016. World Health Organization (WHO) indicators and updated Beers Criteria were used to assess the drug utilization pattern and the prevalence of potentially inappropriate medications (PIMs), respectively. Results: The prescriptions of 250 geriatrics patients with a distribution of 57.6% male and 42.4% female were assessed for this study. The total numbers of drugs recorded from the prescriptions were 1635 drugs, with an average of 6.54 drugs per person. According to the Beers Criteria, it was found that nearly 23.05% of the total prescribed drugs were potentially inappropriate. Conclusion: Polypharmacy and use of inappropriate medicines presents a health risk to the geriatric population. Causes could include healthcare practitioner shortage, lack of awareness of PIMs, not understanding drug interaction, and the need for multiple drugs. Prescriber training and retraining is needed.
