Introduction: Immune reconstitution inflammatory syndrome (IRIS) is paradoxical clinical deterioration experienced
by some HIV-infected patients in response to antiretroviral therapy (ART). There is still limited published data on
IRIS from this region including Malaysia. This study aimed to determine IRIS prevalence, clinical manifestations
and possible predictors among HIV-infected patients in an infectious disease centre in Peninsular Malaysia.
Method: This retrospective study was conducted in Hospital Sungai Buloh involving secondary data of 256
HIV-infected patients who were initiated on ART in the year 2017. Medical record of each patient was reviewed
for up to 12 months following ART initiation to identify IRIS diagnosis which was made by the treating physician.
Relevant clinical and laboratory information were retrieved from hospital electronic database. Results: IRIS has
occurred in 17.6% of patients. Infections by Mycobacterium tuberculosis (53.3%), Pneumocystis jirovecii (11.1%)
and Talaromyces marneffei (6.6%) were the commonest three aetiologies of IRIS. Subacute lupus erythematosus was
the only non-infectious IRIS identified. Baseline HIV viral load, CD4+ T-cell count and haemoglobin level between
IRIS and non-IRIS patients were significantly different. Risk of developing IRIS was increased seven times in patients
with CD4+ T-cell count < 100 cells/µL and four times in patients with HIV RNA viral load > 5.5 log10 copies/ml prior
to ART initiation. Conclusion: Mycobacterium tuberculosis infections were the highest IRIS manifestation. Although
rare, non-infectious IRIS does occur and should be part of the differential diagnosis. Patients with positive predictors
should be appropriately monitored for possible IRIS development once initiated on ART.
Suppurative BCG lymphadenitis can easily be overlooked, as it mimics other diseases such as tuberculous lymphadenitis. A case of a three-month old female infant who received the BCG vaccination at birth presented with isolated left axillary mass at two months of age. She was initially treated as lymph node abscess but was referred to the hospital due to the increasing size of the swelling. Needle aspiration was done and the microbiology analysis came out positive for acid-fast bacilli. She was planned for syrup isoniazid; however, the management team withheld treatment until they were certain of the identity of the bacteria. The bacteria was confirmed by the molecular method to be Mycobacterium bovis BCG strain. The case report highlights the importance of the microbiology investigations for appropriate management in this case.
