Prevalence of microalbuminuria and associated factors among HIV - infected ART naïve patients at Mulago hospital: a cross-sectional study in Uganda.

BACKGROUND: HIV infection affects multiple organs and the kidney is a common target making renal disease, one of the recognized complications. Microalbuminuria represents an early, important marker of kidney damage in several populations including HIV-infected antiretroviral therapy (ART) naïve patients. Early detection of microalbuminuria is critical to slowing down progression to chronic kidney disease (CKD) in HIV-infected patients, however, the burden of microalbuminuria in HIV-infected antiretroviral therapy (ART) naïve patients in Uganda is unclear. METHODS: A cross-sectional study was conducted in the Mulago Immune suppression syndrome (ISS) clinic among adult HIV - infected ART naïve outpatients. Data on patient demographics, medical history was collected. Physical examination was performed to assess body mass index (BMI) and hypertension. A single spot morning urine sample from each participant was analysed for microalbuminuria using spectrophotometry and colorimetry. Microalbuminuria was defined by a urine albumin creatinine ratio (UACR) 30-299 mg/g and macroalbuminuria by a UACR > 300 mg/g. To assess the factors associated with microalbuminuria, chi-square, Fisher's exact test, quantile regression and logistic regression were used. RESULTS: A total of 185 adult participants were consecutively enrolled with median age and CD4+ counts of 33(IQR = 28-40) years and 428 (IQR = 145-689) cells/µL respectively. The prevalence of microalbuminuria was 18.9% (95% CI, 14-25%). None of the participants had macroalbuminuria. CD4+ count <350cells/µL was associated with increased risk of microalbuminuria (OR: 0.27, 95% CI: 0.12-0.59), P value = 0.001). Diabetes mellitus, hypertension, smoking, alcohol intake were not found to be significantly associated with microalbuminuria. CONCLUSION: Microalbuminuria was highly prevalent in adult HIV - infected ART naive patients especially those with low CD4+ count. There is need to study the effect of ART on microalbuminuria in adult HIV - infected patients.

Thirty years old lady with nephrotic syndrome: a case of biopsy proven lupus nephritis in Tanzania.

We describe a case of a 30 years old female patient who presented with nephrotic syndrome and impaired renal function diagnosed to have systemic lupus erythematosus (SLE). This is the first biopsy proven lupus nephritis in Tanzania. SLE is common among females and is reported be more common among Africans as compared to other races. This patient presented with nephrotic syndrome, pleural effusion and pericardial effusion which depicts the multisystem effects of SLE. This patient was treated with cyclophosphamide in combination with steroid as induction therapy and attained remission after a month of treatment. Systemic lupus erythematosus should be considered in patients with nephrotic syndrome and these patients should have renal biopsy to determine renal involvement.
